Section 2 hereof, 83,682  fully paid and nonassessable shares of the Company's
Common Stock, par value $0.001 per share (the "COMMON STOCK"), at an exercise
price per share (the "EXERCISE PRICE") of  $16.43  (and in no event less than
$0.001). The number of shares of Common Stock purchasable hereunder (the
"WARRANT SHARES") and the Exercise Price are subject to adjustment as provided

warrants, if any, of the Company issued in connection with the Securities

                                       1
<PAGE>

      1.  MANNER OF EXERCISE; ISSUANCE OF CERTIFICATES; PAYMENT FOR SHARES.
          ---------------------------------------------------------------- 
Subject to the provisions hereof, including, without limitation, the limitations
contained in Section 7 hereof, this Warrant may be exercised by the holder
hereof, in whole or in part by the surrender of this Warrant, together with a
completed exercise agreement in the form attached hereto (the "EXERCISE
AGREEMENT"), to the Company during normal business hours on any business day at
the Company's principal executive offices (or such other office or agency of the
Company as it may designate by notice to the holder hereof), and upon (i)
payment to the Company in cash, by certified or official bank check or by wire
transfer for the account of the Company, of the Exercise Price for the Warrant
Shares specified in the Exercise Agreement or (ii) if the resale of the Warrant
Shares by the holder is not then registered pursuant to an effective
registration statement under the Securities Act of 1933, as amended (the
"SECURITIES ACT"), delivery to the Company of a written notice of an election to
effect a Net Issuance (as defined in Section 11(c) below) for the Warrant Shares
specified in the Exercise Agreement. The Warrant Shares so purchased shall be
deemed to be issued to the holder hereof or such holder's designee, as the
record owner of such shares, as of the close of business on the date on which
this Warrant shall have been surrendered, the completed Exercise Agreement shall
have been delivered, and payment shall have been made for such shares as set
forth above. Certificates for the Warrant Shares so purchased, representing the
aggregate number of shares specified in the Exercise Agreement, shall be
delivered to the holder hereof within a reasonable time, not exceeding three (3)
business days, after this Warrant shall have been so exercised. The certificates
so delivered shall be in such denominations as may be requested by the holder
hereof and shall be registered in the name of such holder or such other name as
shall be designated by such holder. If this Warrant shall have been exercised
only in part, then, unless this Warrant has expired, the Company shall, at its
expense, at the time of delivery of such certificates, deliver to the holder a
new Warrant representing the number of shares with respect to which this Warrant
shall not then have been exercised.  In the alternative, the holder hereof may
elect to effect exercises of this Warrant through one or more transactions of a
type commonly referred to as a "cashless exercise" in conformity with the
provisions of Regulation T of the Federal Reserve Board of Governors (each a
"CASHLESS EXERCISE").  To effect a Cashless Exercise of this Warrant, the holder
hereof shall deliver to the Company and to a broker selected by such holder and
acceptable to the Company in its reasonable discretion such holder's completed
Exercise Agreement together with instructions for the Company to deliver to such
broker the Warrant Shares issuable upon such exercise, and the Company shall
take such actions as are necessary and appropriate to facilitate such Cashless
Exercise, including (without limitation) to verify to such broker that it will
deliver, and to deliver, such Warrant Shares promptly to such broker.

      2.  PERIOD OF EXERCISE.  This Warrant is exercisable at any time or from
          ------------------                                                 
time to time on or after the date on which this Warrant is issued and before
5:00 p.m., New York City time on the fifth (5th) anniversary of the date of
issuance (the "EXERCISE PERIOD").

      3.  CERTAIN AGREEMENTS OF THE COMPANY.  The Company hereby covenants and
          ---------------------------------                                  
agrees as follows:

                                       2
<PAGE>

          (a) SHARES TO BE FULLY PAID.  All Warrant Shares will, upon issuance
              -----------------------                                        
in accordance with the terms of this Warrant, be validly issued, fully paid, and
nonassessable and free from all taxes, liens, claims and encumbrances.

          (b) RESERVATION OF SHARES.  During the Exercise Period, the Company
              ---------------------                                         
shall at all times have authorized, and reserved for the purpose of issuance
upon exercise of this Warrant, a sufficient number of shares of Common Stock to
provide for the exercise of this Warrant.

          (c) LISTING.  The Company shall promptly secure the listing of the
              -------                                                      
shares of Common Stock issuable upon exercise of this Warrant upon each national
securities exchange or automated quotation system, if any, upon which shares of
Common Stock are then listed or become listed (subject to official notice of
issuance upon exercise of this Warrant) and shall maintain, so long as any other
shares of Common Stock shall be so listed, such listing of all shares of Common
Stock from time to time issuable upon the exercise of this Warrant; and the
Company shall so list on each national securities exchange or automated
quotation system, as the case may be, and shall maintain such listing of, any
other shares of capital stock of the Company issuable upon the exercise of this
Warrant if and so long as any shares of the same class shall be listed on such
national securities exchange or automated quotation system.

          (d) CERTAIN ACTIONS PROHIBITED.  The Company will not, by amendment of
              --------------------------                                       
its charter or through any reorganization, 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 by it hereunder, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant and in the
taking of all such action as may reasonably be requested by the holder of this
Warrant in order to protect the exercise privilege of the holder of this Warrant
against dilution or other impairment, consistent with the tenor and purpose of
this Warrant. Without limiting the generality of the foregoing, the Company (i)
will not increase the par value of any shares of Common Stock receivable upon
the exercise of this Warrant above the Exercise Price then in effect, and (ii)
will take all such actions as may be necessary or appropriate in order that the
Company may validly and legally issue fully paid and nonassessable shares of
Common Stock upon the exercise of this Warrant.

          (e) SUCCESSORS AND ASSIGNS. This Warrant will be binding upon any
              ----------------------                                      
entity succeeding to the Company by merger, consolidation, or acquisition of all
or substantially all of the Company's assets.

      4.  ANTIDILUTION PROVISIONS.  During the Exercise Period, the Exercise
          -----------------------                                          
Price and the number of Warrant Shares shall be subject to adjustment from time
to time as provided in this Section 4.

     In the event that any adjustment of the Exercise Price as required herein
results in a fraction of a cent, such Exercise Price shall be rounded up to the
nearest cent.

          (a) ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES UPON ISSUANCE OF
              ------------------------------------------------------------------
COMMON STOCK.  Except as otherwise provided in Sections 4(c) and 4(e) hereof, if
- ------------                                                                   
and whenever

                                       3
<PAGE>

on or after the date of the Closing under and as defined in the
Securities Purchase Agreement, the Company issues or sells, or in accordance
with Section 4(b) hereof is deemed to have issued or sold, any shares of Common
Stock for no consideration or for a consideration per share less than the Market
Price (as hereinafter defined) on the date of issuance ("DILUTIVE ISSUANCE"),
then effective immediately upon the Dilutive Issuance, the Exercise Price will
be adjusted in accordance with the following formula:


     E' = E  x        O+P/M
                  -------------
                      CSDO
     where:

     E'    =      the adjusted Exercise Price;
     E     =      the then current Exercise Price;
     M     =      the then current Market Price (as defined in Section 4(1));
     O     =      the number of shares of Common Stock outstanding immediately
                  prior to the Dilutive Issuance;
     P     =      the aggregate consideration, calculated as set forth in
                  Section 4(b) hereof, received by the Company upon such
                  Dilutive Issuance; and
     CSDO  =      the total number of shares of Common Stock Deemed Outstanding
                  (as defined in Section 4(1)) immediately after the Dilutive
                  Issuance.


          (b) EFFECT ON EXERCISE PRICE OF CERTAIN EVENTS.  For purposes of
              ------------------------------------------                 
determining the adjusted Exercise Price under Section 4(a) hereof, the following
will be applicable:

                (i) ISSUANCE OF RIGHTS OR OPTIONS.  If the Company in any manner
                    -----------------------------                              
issues or grants any warrants, rights or options, whether or not immediately
exercisable, to subscribe for or to purchase Common Stock or other securities
exercisable, convertible into or exchangeable for Common Stock ("CONVERTIBLE
SECURITIES") (such warrants, rights and options to purchase Common Stock or
Convertible Securities are hereinafter referred to as "OPTIONS") and the price
per share for which Common Stock is issuable upon the exercise of such Options
is less than the Market Price on the date of issuance ("BELOW MARKET OPTIONS"),
then the maximum total number of shares of Common Stock issuable upon the
exercise of all such Below Market Options (assuming full exercise, conversion or
exchange of Convertible Securities, if applicable) will, as of the date of the
issuance or grant of such Below Market Options, be deemed to be outstanding and
to have been issued and sold by the Company for such price per share.  For
purposes of the preceding sentence, the "price per share for which Common Stock
is issuable upon the exercise of such Below Market Options" is determined by
dividing (i) the total amount, if any, received or receivable by the Company as
consideration for the issuance or granting of all such Below Market Options,
plus the minimum aggregate amount of additional consideration, if any, payable
to the Company upon the exercise of all such Below Market Options, plus, in the
case of Convertible Securities issuable upon the exercise of such Below Market
Options, the minimum aggregate amount of additional consideration payable upon
the exercise, conversion or exchange thereof at the time such Convertible
Securities first become exercisable, convertible or exchangeable, by (ii) the
maximum total number of shares of Common Stock issuable upon the exercise of all
such Below Market Options (assuming full conversion of Convertible Securities,
if applicable). No further adjustment to the Exercise Price will be made upon
the actual issuance of such Common Stock upon the exercise of such Below Market

                                       4
<PAGE>

Options or upon the exercise, conversion or exchange of Convertible Securities
issuable upon exercise of such Below Market Options.

                (ii) ISSUANCE OF CONVERTIBLE SECURITIES.
                     ----------------------------------

                      (A)  If the Company in any manner issues or sells any
Convertible Securities, whether or not immediately convertible (other than where
the same are issuable upon the exercise of Options) and the price per share for
which Common Stock is issuable upon such exercise, conversion or exchange (as
determined pursuant to Section 4(b)(ii)(B) if applicable) is less than the
Market Price on the date of issuance, then the maximum total number of shares of
Common Stock issuable upon the exercise, conversion or exchange of all such
Convertible Securities will, as of the date of the issuance of such Convertible
Securities, be deemed to be outstanding and to have been issued and sold by the
Company for such price per share. For the purposes of the preceding sentence,
the "price per share for which Common Stock is issuable upon such exercise,
conversion or exchange" is determined by dividing (i) the total amount, if any,
received or receivable by the Company as consideration for the issuance or sale
of all such Convertible Securities, plus the minimum aggregate amount of
additional consideration, if any, payable to the Company upon the exercise,
conversion or exchange thereof at the time such Convertible Securities first
become exercisable, convertible or exchangeable, by (ii) the maximum total
number of shares of Common Stock issuable upon the exercise, conversion or
exchange of all such Convertible Securities. No further adjustment to the
Exercise Price will be made upon the actual issuance of such Common Stock upon
exercise, conversion or exchange of such Convertible Securities.

                      (B)  If the Company in any manner issues or sells any
Convertible Securities with a fluctuating conversion or exercise price or
exchange ratio (a "VARIABLE RATE CONVERTIBLE SECURITY"), then the price per
share for which Common Stock is issuable upon such exercise, conversion or
exchange for purposes of the calculation contemplated by Section 4(b)(ii)(A)
shall be deemed to be the lowest price per share which would be applicable
(assuming all holding period and other conditions to any discounts contained in
such Convertible Security have been satisfied) if the Market Price on the date
of issuance of such Convertible Security was 75% of the Market Price on such
date (the "ASSUMED VARIABLE MARKET PRICE"). Further, if the Market Price at any
time or times thereafter is less than or equal to the Assumed Variable Market
Price last used for making any adjustment under this Section 4 with respect to
any Variable Rate Convertible Security, the Exercise Price in effect at such
time shall be readjusted to equal the Exercise Price which would have resulted
if the Assumed Variable Market Price at the time of issuance of the Variable
Rate Convertible Security had been 75% of the Market Price existing at the time
of the adjustment required by this sentence.

                (ii) CHANGE IN OPTION PRICE OR CONVERSION RATE.  If there is a
                     -----------------------------------------               
change at any time in (i) the amount of additional consideration payable to the
Company upon the exercise  of any Options; (ii) the amount of additional
consideration, if any, payable to the Company upon the exercise, conversion or
exchange of any Convertible Securities; or (iii) the rate at which any
Convertible Securities are convertible into or exchangeable for Common Stock
(other than under or by reason of provisions designed to protect against
dilution), the Exercise Price in effect at the time of such change will be
readjusted to the Exercise Price which would have been in effect at such time
had such Options or Convertible Securities still outstanding

                                       5
<PAGE>

provided for such changed additional consideration or changed conversion rate,
as the case may be, at the time initially granted, issued or sold.

                (iv) TREATMENT OF EXPIRED OPTIONS AND UNEXERCISED CONVERTIBLE
                     --------------------------------------------------------
SECURITIES.  If, in any case, the total number of shares of Common Stock
- ----------                                                             
issuable upon exercise of any Option or upon exercise, conversion or exchange of
any Convertible Securities is not, in fact, issued and the rights to exercise
such Option or to exercise, convert or exchange such Convertible Securities
shall have expired or terminated, the Exercise Price then in effect will be
readjusted to the Exercise Price which would have been in effect at the time of
such expiration or termination had such Option or Convertible Securities, to the
extent outstanding immediately prior to such expiration or termination (other
than in respect of the actual number of shares of Common Stock issued upon
exercise or conversion thereof), never been issued.

                (v) CALCULATION OF CONSIDERATION RECEIVED.  If any Common Stock,
                    -------------------------------------                      
Options or Convertible Securities are issued, granted or sold for cash, the
consideration received therefor for purposes of this Warrant will be the amount
received by the Company therefor, before deduction of reasonable commissions,
underwriting discounts or allowances or other reasonable expenses paid or
incurred by the Company in connection with such issuance, grant or sale.  In
case any Common Stock, Options or Convertible Securities are issued or sold for
a consideration part or all of which shall be other than cash, the amount of the
consideration other than cash received by the Company will be the fair market
value of such consideration, except where such consideration consists of
securities, in which case the amount of consideration received by the Company
will be the Market Price thereof as of the date of receipt. In case any Common
Stock, Options or Convertible Securities are issued in connection with any
merger or consolidation in which the Company is the surviving corporation, the
amount of consideration therefor will be deemed to be the fair market value of
such portion of the net assets and business of the non-surviving corporation as
is attributable to such Common Stock, Options or Convertible Securities, as the
case may be.  The fair market value of any consideration other than cash or
securities will be determined: (a) by the Board of Directors of the Company in
cases where the Common Stock, Options or Convertible Securities are issued to
Strategic Partners (as defined below) or to employees, independent contractors
or others who perform services for the Company (provided that such determination
shall be made in good faith and be based upon the assessment by the Board of
Directors of the value of the services provided to the Company); and (b) in all
other cases, in good faith by an investment banker or other appropriate expert
of national reputation selected by the Company and reasonably acceptable to the
holders hereof, with the costs of such appraisal to be borne by the Company.
For purposes of this Warrant, the term "STRATEGIC PARTNER" means a person or
entity with whom the Company has entered, or proposes to enter, into a strategic
relationship involving the sale, marketing, manufacturing, or development of
products of the Company or such other person or entity.

                (vi) EXCEPTIONS TO ADJUSTMENT OF EXERCISE PRICE.  No adjustment
                     ------------------------------------------               
to the Exercise Price will be made (i) upon the exercise of any warrants,
options or convertible securities issued and outstanding on the date of the
Closing as defined in  the Securities Purchase Agreement in accordance with the
terms of such securities as of such date; (ii) upon the grant or exercise of any
stock or options which may hereafter be granted or exercised under any employee
benefit plan of the Company now existing or to be implemented in the future, so
long as the issuance of such stock or options is approved by a majority of the
non-employee members

                                       6
<PAGE>

of the Board of Directors of the Company or a majority of the members of a
committee of non-employee directors established for such purpose; (iii) upon the
exercise of the Warrants; (iv) upon the issuance of any Adjustment Shares as
defined in the Securities Purchase Agreement and issued in accordance with its
terms; or (v) upon the issuance of the Warrant, the Initial Shares, the
Adjustment Shares or the Warrant Shares as defined in the Securities Purchase
Agreement dated as of July 30, 1998 between the Company and Capital Venture
International (the "CVI SECURITIES PURCHASE AGREEMENT") and as issued in
accordance with the terms of such agreement or the Warrant, as applicable.

          (c) SUBDIVISION OR COMBINATION OF COMMON STOCK.  If the Company at any
              ------------------------------------------                       
time after the closing under the Securities Purchase Agreement subdivides (by
any stock split, stock dividend, recapitalization, reorganization,
reclassification or otherwise) its shares of Common Stock into a greater number
of shares, then, after the date of record for effecting such subdivision, the
Exercise Price in effect immediately prior to such subdivision will be
proportionately reduced.  If the Company at any time after the closing under the
Securities Purchase Agreement combines (by reverse stock split,
recapitalization, reorganization, reclassification or otherwise) its shares of
Common Stock into a smaller number of shares, then, after the date of record for
effecting such combination, the Exercise Price in effect immediately prior to
such combination will be proportionately increased.

          (d) ADJUSTMENT IN NUMBER OF SHARES.  Upon each adjustment of the
              ------------------------------                             
Exercise Price pursuant to the provisions of this Section 4, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be adjusted
by multiplying a number equal to the Exercise Price in effect immediately prior
to such adjustment by the number of shares of Common Stock issuable upon
exercise of this Warrant immediately prior to such adjustment and dividing the
product so obtained by the adjusted Exercise Price.

          (e)  CONSOLIDATION, MERGER OR SALE.  In case of any consolidation of
               -----------------------------                                 
the Company with, or merger of the Company into any other entity, or in case of
any sale or conveyance of all or substantially all of the assets of the Company
other than in connection with a plan of complete liquidation of the Company at
any time after the closing under the Securities Purchase Agreement, then as a
condition of such consolidation, merger or sale or conveyance, adequate
provision will be made whereby the holder of this Warrant will have the right,
at its sole option,  to acquire and receive upon exercise of this Warrant in
lieu of the shares of Common Stock immediately theretofore acquirable upon the
exercise of this Warrant, (i) such shares of stock, securities or assets as may
be issued or payable with respect to or in exchange for the number of shares of
Common Stock immediately theretofore acquirable and receivable upon exercise of
this Warrant had such consolidation, merger or sale or conveyance not taken
place, or (ii) the fair value of this Warrant based on an exercise price equal
to the market price of the Common Stock immediately prior to the first public
announcement of such consolidation, merger or sale or conveyance, otherwise
disregarding the existence of such transaction. In any such case, the Company
will make appropriate provision to insure that the provisions of this Section 4
hereof will thereafter be applicable as nearly as may be in relation to any
shares of stock or securities thereafter deliverable  upon the exercise of this
Warrant. The Company will not effect any consolidation, merger or sale or
conveyance unless prior to the consummation thereof, the successor corporation
(if other than the  Company) assumes by written instrument the obligations under
this Section 4 and the obligations to deliver to the holder of this Warrant

                                       7
<PAGE>

such shares of stock, securities or assets as, in accordance with the foregoing
provisions, the holder may be entitled to acquire.

          (f) DISTRIBUTION OF ASSETS.  In case the Company shall declare or make
              ----------------------                                           
any distribution of its assets (or rights to acquire its assets) to holders of
Common Stock as a partial liquidating dividend, by way of return of capital or
otherwise (including any dividend or distribution to the Company's shareholders
of cash or shares (or rights to acquire shares) of capital stock of a
subsidiary) (a "DISTRIBUTION") at any time after the closing under the
Securities Purchase Agreement, then the holder of this Warrant shall be entitled
upon exercise of this Warrant for the purchase of any or all of the shares of
Common Stock subject hereto, to receive the amount of such assets (or rights)
which would have been payable to the holder had such holder been the holder of
such shares of Common Stock on the record date for the determination of
shareholders entitled to such Distribution.

          (g)  NOTICE OF ADJUSTMENT.  Upon the occurrence of any event which
               --------------------                                        
requires any adjustment of the Exercise Price, then, and in each such case, the
Company shall give notice thereof to the holder of this Warrant, which notice
shall state the Exercise Price resulting from such adjustment and the increase
or decrease in the number of Warrant Shares, setting forth in reasonable detail
the method of calculation and the facts upon which such calculation is based.
Such calculation shall be certified by the chief financial officer of the
Company.

          (h) MINIMUM ADJUSTMENT OF EXERCISE PRICE.  No adjustment of the
              ------------------------------------                      
Exercise Price shall be made in an amount of less than 1% of the Exercise Price
in effect at the time such adjustment is otherwise required to be made, but any
such lesser adjustment shall be carried forward and shall be made at the time
and together with the next subsequent adjustment which, together with any
adjustments so carried forward, shall amount to not less than 1% of such
Exercise Price.

          (i) NO FRACTIONAL SHARES.  No fractional shares of Common Stock are to
              --------------------                                             
be issued upon the exercise of this Warrant, but the Company shall pay a cash
adjustment in respect of any fractional share which would otherwise be issuable

          (j) OTHER NOTICES.  In case at any time:
              -------------

                (ii) the Company shall offer for subscription pro rata to the

subscription rights or for determining the holders of Common Stock entitled to

Securities Purchase Agreement, any event occurs of the type contemplated by the
adjustment provisions of this Section 4 but not expressly provided for by such
provisions, the Company will give notice of such event as provided in Section
4(g) hereof, and the Company's Board of Directors will make an appropriate
adjustment in the Exercise Price and the number of shares of Common Stock
acquirable upon exercise of this Warrant so that the rights of the holder shall
be neither enhanced nor diminished by such event.

          (l)  CERTAIN DEFINITIONS.
               -------------------

                (i)  "COMMON STOCK DEEMED OUTSTANDING" shall mean the number

Stock held in the treasury of the Company), plus (x) in the case of any
adjustment required by Section 4(a) resulting from the issuance of any Options,
the maximum total number of shares of Common Stock issuable upon the exercise of
the Options for which the adjustment is required (including any Common Stock
issuable upon the conversion of Convertible Securities issuable upon the
exercise of such Options), and (y) in the case of any adjustment required by
Section 4(a) resulting from the issuance of any Convertible Securities, the
maximum total number of shares of Common Stock issuable upon the exercise,
conversion or exchange of the Convertible Securities for which the adjustment is
required, as of the date of issuance of such Convertible Securities, if any.

                (ii) "MARKET PRICE," as of any date, (i) means the average of
                      ------------

the shares of Common Stock, the average of the last reported bid prices on the
principal trading market for the Common Stock during the same period, or, if
there is no bid price for such period, the last reported sales price for such
period,

or (iii) if market value cannot be calculated as of such date on any of
the foregoing bases, the Market Price shall be the average fair market value as
reasonably determined by an investment banking firm selected by the Company and
reasonably acceptable to the holder, with the costs of the appraisal to be borne
by the Company. The manner of determining the Market Price of the Common Stock
set forth in the foregoing definition shall apply with respect to any other
security in respect of which a determination as to market value must be made
hereunder.  Notwithstanding the other provisions of this Section 4(1)(ii), the
Market Price of shares of Common Stock issued by the Company (x) to any
Strategic Partner shall mean the value for such shares as determined in good
faith by the Company's Board of Directors taking into consideration all the

includes the Common Stock and any additional class of stock of the Company
having no preference as to dividends or distributions on liquidation, provided
that the shares purchasable pursuant to this Warrant shall include only Common
Shares, par value $0.001 per share, in respect of which this Warrant is
exercisable, or shares resulting from any subdivision or combination of such
Common Stock, or in the case of any reorganization, reclassification,
consolidation, merger, or sale of the character referred to in Section 4(e)
hereof, the stock or other securities or property provided for in such Section.

      5.  ISSUE TAX.  The issuance of certificates for Warrant Shares upon the

exercise of this Warrant shall be made without charge to the holder of this
Warrant or such shares for any issuance tax or other costs in respect thereof,
provided that the Company shall not be required to pay any tax which may be

certificate in a name other than the holder of this Warrant.

      6.  NO RIGHTS OR LIABILITIES AS A SHAREHOLDER.  This Warrant shall not
          -----------------------------------------                        
entitle the holder hereof to any voting rights or other rights as a shareholder
of the Company. No provision of this Warrant, in the absence of affirmative
action by the holder hereof to purchase the Warrant Shares, and no mere
enumeration herein of the rights or privileges of the holder hereof, shall give
rise to any liability of such holder for the Exercise Price or as a shareholder
of the Company, whether such liability is asserted by the Company or by
creditors of the Company.

      7.  TRANSFER. EXCHANGE. REDEMPTION AND REPLACEMENT OF WARRANT.
          ---------------------------------------------------------

          (a) RESTRICTION ON TRANSFER.  This Warrant and the rights granted to

the holder hereof are transferable,  in whole or in part, upon surrender of this
Warrant, together with a properly executed assignment in the form attached

below, provided, however, that any transfer or assignment shall be subject to
the conditions set forth in Sections 7(f) and (g) hereof and to the provisions
of Section 2(f) of the Securities Purchase Agreement. Until due presentment for
registration of transfer on the books of the Company, the Company may treat the

                                       10

in accordance with the provisions of that certain Registration Rights Agreement,
dated as of July 30, 1998 by and among the Company and the other signatory
thereto (the "REGISTRATION RIGHTS AGREEMENT").

          (b) WARRANT EXCHANGEABLE FOR DIFFERENT DENOMINATIONS.  This Warrant is
              ------------------------------------------------                 
exchangeable, upon the surrender hereof by the holder hereof at the office or
agency of the Company referred to in Section 7(e) below, for new Warrants of
like tenor of different denominations representing in the aggregate the right to
purchase the number of shares of Common Stock which may be purchased hereunder,
each of such new Warrants to represent the right to purchase such number of
shares as shall be designated by the holder hereof at the time of such
surrender.

          (c)  REPLACEMENT OF WARRANT.  Upon receipt of evidence reasonably
               ----------------------                                     
satisfactory to the Company of the loss, theft, destruction, or mutilation of
this Warrant and, in the case of any  such loss, theft, or destruction, upon
delivery of an indemnity agreement reasonably satisfactory in form and amount to
the Company, or, in the case of any such mutilation, upon surrender and
cancellation of this Warrant, the Company, at its expense, will execute and
deliver, in lieu thereof, a new Warrant of like tenor.

          (d)  CANCELLATION; PAYMENT OF EXPENSES.  Upon the surrender of this
               ---------------------------------                            
Warrant in connection with any transfer, exchange, or replacement as provided in
this Section 7, this Warrant shall be promptly canceled by the Company. The
Company shall pay all taxes (other than securities transfer taxes) and all other
expenses (other than legal or due diligence expenses, if any, incurred by the
Holder or transferees) and charges payable in connection with the preparation,
execution, and delivery of Warrants pursuant to this Section 7.

          (e)  WARRANT REGISTER.  The Company shall maintain, at its principal
               ----------------                                              
executive offices (or such other office or agency of the Company as it may
designate by notice to the holder hereof), a register for this Warrant, in which
the Company shall record the name and address of the person in whose name this
Warrant has been issued, as well as the name and address of each transferee and
each prior owner of this Warrant.

          (f)  EXERCISE OR TRANSFER WITHOUT REGISTRATION.  If, at the time of
               -----------------------------------------                    
the surrender of this Warrant in connection with any exercise, transfer, or
exchange of this Warrant, this Warrant (or, in the case of any exercise, the
Warrant Shares issuable hereunder), shall not be registered under the Securities
Act and under applicable state securities or blue sky laws, the Company may
require, as a condition of allowing such exercise, transfer, or exchange, (i)
that the holder or transferee of this Warrant, as the case may be, furnish to
the Company a written opinion of counsel, which counsel shall be reasonably
acceptable to the Company  (which opinion shall be in form, substance and scope
customary for opinions of counsel in comparable transactions) to the effect that
such exercise, transfer, or exchange may be made without registration under the
Securities Act and under applicable state securities or blue sky laws, (ii) that
the holder or transferee execute and deliver to the Company an investment letter
in form and substance acceptable to the Company and (iii) that the transferee be
an "ACCREDITED INVESTOR"

                                       11
<PAGE>

as defined in Rule 501(a) promulgated under the Securities Act; provided that no
such opinion, letter or status as an "accredited investor" shall be required in
connection with a transfer pursuant to Rule 144 under the Securities Act.

          (g) ADDITIONAL RESTRICTIONS ON EXERCISE OR TRANSFER.  Notwithstanding
              -----------------------------------------------                 
anything contained herein to the contrary, in no event shall the holder hereof
exercise Warrants to the extent  that (a) the number of shares of Common Stock
beneficially owned by such holder and its affiliates (other than shares of
Common Stock which may be deemed beneficially owned through the ownership of the
unexercised portion of the Warrants or the unexercised or unconverted portion of
any other securities (including, without limitation, the Preferred Stock) of the
Company subject to a limitation on conversion or exercise analogous to the
limitation contained herein) and (b) the number of shares of Common Stock
issuable upon exercise of the Warrants (or portion thereof) with respect to
which the determination described herein is being made, would result in
beneficial Ownership by such holder and its affiliates of more than 4.9% of the
outstanding shares of Common Stock. For purposes of the immediately preceding
sentence, beneficial ownership shall be determined in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended, and Regulation 13D-G
thereunder, except as otherwise provided in clause (a) hereof. In addition, no
Subject Holder (as defined below) may sell or otherwise transfer in a private
sale which is not a Permitted Sale (as defined below) during any ninety (90) day
period a portion(s) of the Warrants or any other securities of the Company
subject to limitations on sale or transfer analogous to the limitations
contained herein, which, if exercised for or converted into Common Stock at the
time of the transfer, would represent, in the aggregate (together with any other
shares of Common Stock transferred), beneficial ownership by the transferee(s)
of more than 4.9% of the Common Stock then outstanding. For purposes of this
paragraph, (i) "SUBJECT HOLDER" means any holder of Warrants who, but for the
provisions of the immediately preceding Section and this Section, may be deemed
to beneficially own 5% or more of the outstanding Common Stock of the Company
and (ii) "PERMITTED SALE" means any sale or transfer (x) to the Company or to a
shareholder or a group of shareholders who immediately prior to the sale control
a majority of the Company's voting shares; (y) to an affiliate of such holder;
or (z) in connection with any merger, consolidation, reorganization or sale of
more than 50% of the outstanding Common Stock of the Company. The first holder
of this Warrant, by taking and holding the same, represents to the Company that
such holder is acquiring this Warrant for investment only and not with a view to
the distribution thereof, except pursuant to sales that are exempt from the
registration requirements of the Securities Act and/or sales registered under
the Securities Act.

      8.  REGISTRATION RIGHTS.  The initial holder of this Warrant (and certain
          -------------------                                                 
assignees thereof) is entitled to the benefit of such registration rights in
respect of the Warrant Shares as are set forth in the Registration Rights

may be enforced in other jurisdictions by suit on such judgment or in any other
lawful manner.

          -------------

          (a) AMENDMENTS.  This Warrant and any provision hereof may only be
              ----------

              --------------------                                         
Sections of this Warrant are inserted for purposes of reference only, and shall
not affect the meaning or construction of any of the provisions hereof.

          (c) NET ISSUANCE.  Notwithstanding anything to the contrary contained
              ------------                                                    
in this Warrant, if  this Warrant cannot be exercised through the means of a
Cashless Exercise in a commercially reasonable manner, this Warrant may be
exercised at any time during the Exercise Period, by presentation and surrender
of this Warrant to the Company at its principal executive offices with a written
notice of the holder's intention to effect a net issuance, including a
