                            B.   Except for the security interests granted
          hereby, the Pledgor is, and as to Collateral acquired after the date
          hereof the Pledgor shall and will be at the time of acquisition, the
          record and beneficial owner and holder of the Collateral free from any

          encumbrances, liens, charges or other adverse interests by third

                            C.   (i) The Pledgor has full power and lawful
          authority to enter into this Agreement and to pledge the Collateral to
          the Pledgee and to grant to the Pledgee a first and prior security
          interest therein as herein provided, all of which have been duly
          authorized by all necessary corporate action.

                     (ii)   The execution and delivery and the performance
          hereof are not in contravention of any charter, articles of
          incorporation or by-law provision, or of any Instrument or undertaking
          to which the Pledgor is a party or by which the Pledgor or its
          property is bound.

                     (iii)  This Agreement constitutes the valid and legally
          binding obligation of the Pledgor enforceable in accordance with its
          terms.

                     (iv)   The Pledgor will defend the Collateral against all
          claims and demands of all persons at any time claiming the same or any
          interest therein.  Any officer or representative acting for or on

days prior written notice to the Pledgee.

                     (ii)   The preamble hereof states the correct legal name of
          the Pledgor and the Pledgor does not conduct business under any other
          name.  Pledgor shall not change its corporate name, nor do business
          under any name other than its current name, unless the Pledgor has
          delivered to

                                      178
<PAGE>

          the Pledgee written notice of such other names at least 30 days prior
          to the date of first use thereof by the Pledgor.

               (e)   (i)    The Pledgor has not heretofore agreed to or signed
any pledge, charge, financing statement or security agreement which covers any
of the Collateral, and no such pledge, charge, financing statement or security
agreement is now on file in any public office and the Pledgor has not heretofore
filed or inserted any entries or notations in the books or share registry of the
Pledgor or the Pledgor evidencing any pledge of the Collateral (other than such
financing statements, security agreements and share registry notations, if any,
of which both written notice and true and correct copies have heretofore been
given by the Pledgor to the Pledgee).

                     (ii)   As long as any amount remains unpaid on any of the
          Secured Obligations or under any agreement entered into in connection
          with the Secured Obligations, except as expressly permitted by any
          such agreement, (A) the Pledgor will not enter into or execute any
          pledge, charge, security agreement or financing statement covering the
          Collateral, other than those pledges, charges, security agreements and
          financing statements in favor of the Pledgee hereunder, (B) the
          Pledgor shall not file or consent to the filing of any pledge,
          financing statement or statements (or any documents or papers filed as
          such) covering the Collateral, other than financing statements in
          favor of the Pledgee hereunder, unless in any case the prior written
          consent of the Pledgee shall have been obtained, and further (C) the
          Pledgor shall not insert, file or make any notations in the books or
          share registry of the Pledgor evidencing any pledge of the Collateral,
          other than such entries and notations in favor of the Pledgee
          hereunder.

                     (iii)  The Pledgor authorizes the Pledgee to file, in its
          discretion, in jurisdictions where this authorization will be given
          effect, a financing statement, personal property security act filing
          or other instrument for filing required by any jurisdiction applicable
          to the Collateral signed only by the Pledgee covering the Collateral,
          and hereby appoints the Pledgee as the Pledgor's attorney-in-fact to
          sign and file any such financing statements or other instruments
          covering the Collateral.  At the request of the Pledgee, the Pledgor
          will join the Pledgee in executing such Instruments as the Pledgee may
          determine from time to time to be necessary or desirable under
          provisions of any applicable Uniform Commercial Code, Personal
          Property Security Act or other applicable laws in effect where the
          Collateral is located or where the Pledgor conducts business; without
          limiting the generality of the foregoing, the Pledgor agrees to join
          the Pledgee, at the Pledgee's request, in executing one or more
          financing statements or other Instruments in form satisfactory to the
          Pledgee, and the Pledgor will pay the costs of filing or recording the
          same in all public offices at any time and from time to time whenever

                                      179
<PAGE>

          filing or recording of any such financing statement or other
          Instrument is deemed by the Pledgee to be necessary or desirable.

                     XXII.  Rights of the Pledgee and the Pledgor Related to
                     -----  ------------------------------------------------
     Collateral.
     -----------

          The Pledgee may from time to time following the occurrence of an Event
of Default, as defined in the Note or the Purchase Agreement:

                                 A.   Transfer any of the Collateral into the
          name of the Pledgee or its nominee.

                                 B.   Notify parties obligated on any of the
          Collateral to make payment to the Pledgee of any amounts due or to
          become due thereunder.

                                 C.   Subject to compliance with federal and
          state securities laws, enforce collection of any of the Collateral by
          suit or otherwise; surrender, release or exchange all or any part
          thereof, or compromise or extend or renew for any period (whether or
          not longer than the original period) any obligation of any nature of
          any party with respect thereto; and exercise all other rights of the
          Pledgor in any of the Collateral, except as hereinafter provided with
          respect to income from or interest on the Collateral and except that,
          prior to an Event of Default, the Pledgor may exercise its voting and
          consensual rights with respect to any Collateral constituting voting
          securities.

                                 D.   Take possession or control of any proceeds
          of the Collateral.

          Until the occurrence of an Event of Default, the Pledgor shall have
the right to receive all income from or interest on the Collateral, and if the
Pledgee receives any such income or interest prior to the occurrence of an Event
of Default, the Pledgee shall pay the same promptly to the Pledgor, except that
in the case of securities or other property distributed by way of a dividend or
otherwise with respect to the Collateral, such securities or other property
shall be promptly delivered to the Pledgee to be held as Pledged Shares or other
Collateral hereunder.  Upon the occurrence of an Event of Default, the Pledgor
will not demand or receive any income from or interest on the Collateral, and if
the Pledgor receives any such income or interest without any demand by it, the
same shall be held by the Pledgor in trust for the Pledgee in the same medium in
which received, shall not be commingled with any assets of the Pledgor and shall
be delivered to the Pledgee in the form received, properly endorsed to permit
collection, not later than the next business day following the day of its
receipt.  The Pledgee may apply the net cash received from such income or
interest to payment of any of the Secured Obligations, provided that the Pledgee
shall account for and pay over to the Pledgor any such income or interest
remaining after payment in full of the Secured Obligations then outstanding.

                                      180
<PAGE>

          So long as no Event of Default shall have occurred, the Pledgor shall
be entitled to exercise any and all voting and other consensual rights
pertaining to the Collateral or any part thereof for any purpose not
inconsistent with the terms of this Agreement or the Purchase Agreement;
provided, however, that the Pledgor shall not exercise or refrain from
--------  -------
exercising any such right if, in the Pledgee's judgment, such action would have
a material adverse effect on the value of the Collateral or any part thereof;
and, provided, further, that the Pledgor shall give the Pledgee at least five
     --------  -------
days' written notice of the manner in which it intends to exercise, or the
reasons for refraining from exercising, any such rights.

          The Pledgee shall never be under any obligation to collect, attempt to
collect, protect or enforce the Collateral or any security therefor, which the
Pledgor agrees and undertakes to do at the Pledgor's expense, but the Pledgee
may do so in its discretion at any time after the occurrence of an Event of
Default and at such time the Pledgee shall have the right to take any steps by
judicial process or otherwise as it may deem proper to effect the collection of
all or any portion of the Collateral or to protect or to enforce the Collateral
or any security therefor.  All expenses (including, without limitation,
reasonable attorneys' fees and expenses) incurred or paid by the Pledgee in
connection with or incident to any such collection or attempt to collect the
Collateral or actions to protect or enforce the Collateral or any security
therefor shall be borne by the Pledgor or reimbursed by the Pledgor to the
Pledgee upon demand.  The proceeds received by the Pledgee as a result of any
such actions in collecting or enforcing or protecting the Collateral shall be
utilized by the Pledgee in accordance with Section 10 hereof.
                                           ----------

               XXIII.  Further Assurances.
               ------  ------------------

          The Pledgor agrees to take such actions and to execute such stock or
bond powers or other Instruments and such other or different writings as the
Pledgee may reasonably request further to perfect, confirm and assure the
Pledgee's security interest in the Collateral and irrevocably authorizes the
Pledgee, as Pledgor's agent and attorney-in-fact, to assist the Pledgee's
realization thereon upon the occurrence of an Event of Default including,
without limitation, the right to receive, indorse, and collect all instruments
made payable to the Pledgor representing any dividend, interest payment or other
distribution in respect of the Pledged Shares or any part thereof.

               XXIV.   Events of Default.
               -----   -----------------

          The occurrence of an Event of Default under the Note shall constitute
an "Event of Default" hereunder.

               XXV.    Rights and Remedies of the Pledgee Upon Default.
               ----    -----------------------------------------------

          If an Event of Default shall have occurred:

                                 A.   The Pledgee shall have and may, subject to
          compliance with federal and state securities laws, exercise with
          reference to the Collateral and the Secured Obligations any and all of
          the rights and remedies of a secured party under the Uniform
          Commercial Code ("UCC"), and as otherwise granted herein or under any
          other applicable law now or hereafter in effect executed by the
          Pledgor, including, without limitation, the right and power to sell,
          at public or private sale or sales, or otherwise dispose of, or
          otherwise utilize the Collateral and any part or parts thereof in any
          manner authorized or permitted under the UCC after default by a
          debtor, and to apply the proceeds thereof toward payment of any costs
          and expenses and attorneys' fees and expenses thereby incurred by the
          Pledgee and toward payment of the Secured Obligations in such order or
          manner as permitted by law. Specifically and without limiting the
          foregoing, the Pledgee shall have the right to take possession of all
          or any part of the Collateral, any certificate therefor or any
          security therefor and of all books, records, papers and documents of
          the Pledgor or in the Pledgor's possession or control relating to the
          Collateral which are not already in the Pledgee's possession, and for
          such purpose may enter upon any premises upon which any of the
          Collateral or any security therefor or any of said books, records,
          papers and documents are situated and remove the same therefrom
          without any liability for trespass or damages thereby occasioned. To
          the extent permitted by law, the Pledgor expressly waives any notice
          of sale or other disposition of the Collateral and all other rights or
          remedies of the Pledgor or formalities prescribed by law relative to
          sale or disposition of the Collateral or exercise of any other right
          or remedy of the Pledgee existing after default hereunder. The Pledgee
          shall have all other rights and remedies available, whether at law or
          in equity.

                                 B.   Upon notice by the Pledgee to the Pledgor,
          the Pledgee or its nominee or nominees shall have the sole and
          exclusive right to exercise all voting and consensual powers
          pertaining to the Collateral or any part thereof and may exercise such
          powers in such manner as the Pledgee may elect.

                                 C.   All dividends, payments of interest and
          other distributions of every character made upon or in respect of the
          Pledged Shares or any part thereof shall be deemed to be Collateral
          and shall be paid directly to and shall be held by the Pledgee as
          additional Collateral pledged under and subject to this Agreement.

                                      182
<PAGE>

                                 D.   All rights to marshaling of assets of the
          Pledgor, including any such right with respect to the Collateral, are
          hereby waived by the Pledgor.

               XXVI.   Special Provisions for Pledged Shares.
               -----   -------------------------------------

          The Pledgor hereby acknowledges that the sale by the Pledgee of any of
the Pledged Shares pursuant to the terms hereof in compliance with federal and
applicable state or securities laws or the securities laws of any other
applicable jurisdiction exercising valid jurisdiction over the Pledged Shares
(as now in effect or as hereafter amended, or any similar statute hereafter
adopted with similar purpose or effect, the "Securities Laws") may require
strict limitations as to the manner in which the Pledgee or any subsequent
transferee of the Pledged Shares may dispose of such securities.  The Pledgor
understands that in order to protect the Pledgee's interest it may be necessary
to sell the Pledged Shares at a price less than the maximum price attainable if
a sale were delayed or were made in another manner, such as a public offering
requested under the Securities Laws.  The Pledgor has no and waives any
objection to a sale in such a manner.

               XXVII.  Application of Proceeds by the Pledgee.
               ------  --------------------------------------

     1. Exercise.

          (a)  Right to Exercise; Exercise Price. The Holder shall have the
               -----------------  --------------
right to exercise this Warrant at any time and from time to time during the
period beginning on the Issue Date and ending on the Expiration Date as to all

accountant to calculate the Exercise Price and/or the number of Warrant Shares
issuable hereunder and to notify the Company and the Holder of the results in
writing no later than two Business Days following the day on which such

shall be deemed conclusive absent manifest error. The fees of any such
accountant shall be borne by the party whose calculations were most at variance
with those of such accountant.

          (c)  Early Expiration. In the event that following the first
               ----------------

consecutive Trading Days is equal to or greater than twice the Exercise Price
then in effect (an "Expiration Trigger Event"), the Company may deliver to the
                    ------------------------
Holder, within five(5) business days following the occurrence of an Expiration
Trigger Event, a written notice to such effect (a "Expiration Notice") and this
                                                   -----------------

               -----------------------
exercise and, if this Warrant is exercised in part, the Company shall, at the
time that it delivers Warrant Shares to the Holder pursuant to such exercise as
provided herein, issue a new warrant, and deliver to the Holder a certificate
representing such new warrant, with terms identical in all respects to this
Warrant (except that such new warrant shall be exercisable into the number of
shares of Common Stock with respect to which this Warrant shall remain
unexercised); provided, however, that the Holder shall be entitled to exercise
all or any portion of such new warrant at any time following the time at which
this Warrant is exercised, regardless of whether the Company has actually issued
such new warrant or delivered to the Holder a certificate therefor.

     Upon receipt of an Exercise Notice pursuant to paragraph 1 above, the
Company shall, (A) in the case of a Cashless Exercise (as defined below), no

Shares, no later than the close of business on such Delivery Date. Warrant
Shares delivered to the Holder shall contain a restrictive indicating that the
Warrant Shares may not be sold except (i) pursuant to an effective registration
statement under the Securities Act of 1933, as amended, (ii) Rule 144 under the
Securities Act of 1933, as amended, or (iii) pursuant to Rule 144(k) under the
Securities Act of 1933, as amended, or any successor rule or provision.

     3. Failure to Deliver Warrant Shares.

     (a)  Exercise Default. In the event that, as a result of any action or
          ----------------
failure to act on the part of the Company (including without limitation a
failure by the Company to have a sufficient number of shares of Common Stock
authorized and reserved for issuance pursuant to exercise of the Warrants), the
Company does not deliver to a Holder certificates representing the number of
Warrant Shares specified in the applicable Exercise Notice on or before the
Delivery Date therefor and such failure continues for ten (10) Business Days (an
"Exercise Default"), the Company shall pay to the Holder payments ("Exercise
 ----------------                                                   --------
Default Payments") in the amount of (i) (N/365) multiplied by (ii) the aggregate
----------------                                ----------
Exercise Price for the Warrant Shares which are the subject of such Exercise
Default multiplied by (iii) the lower of twenty four percent (24%) and the
        ----------
maximum rate permitted by applicable law, where "N" equals the number of days
elapsed between the original Delivery Date for such Warrant Shares and the date
on which all of such Warrant Shares are issued and delivered to the Holder.
Amounts payable under this subparagraph 3(a) shall be paid to the Holder in
immediately available funds on or before the fifth (5th) Business Day of the
calendar month immediately following the calendar month in which such amount has
accrued.

     (b)  Buy-in. Nothing herein shall limit a Holder's right to pursue actual
          ------
damages for the Company's failure to issue and deliver Warrant Shares in
connection with an exercise on the applicable Delivery Date (including, without
limitation, damages relating to any purchase of shares of Common Stock by the
Holder to make delivery on a sale effected in anticipation of receiving Warrant
Shares upon exercise, such damages to be in an amount equal to (A) the aggregate
amount paid by the Holder for the shares of

                                      192
<PAGE>

Common Stock so purchased minus (B) the aggregate amount of net  proceeds, if
                          -----
any, received by the Holder from the sale of the Warrant Shares issued by the
Company pursuant to such exercise), and the Holder shall have the right to
pursue all remedies available to it at law or in equity (including, without
limitation, a decree of specific performance and/or injunctive relief).

     (c)  Reduction of Exercise Price. In the event that, as a result of any
          ---------------------------
action or failure to act on the part of the Company (including without
limitation a failure by the Company to have a sufficient number of shares of
Common Stock authorized and reserved for issuance pursuant to exercise of the
Warrants), a Holder has not received certificates representing the Warrant
Shares by the tenth (10th) Business Day following an Exercise Default, the
Holder may, upon written notice to the Company, regain on such Business Day the
rights of a Holder of this Warrant, or part thereof, with respect to the Warrant
Shares that are the subject of such Exercise Default, and the Exercise Price for
such Warrant Shares shall be reduced by one percent (1%) for each day beyond
such 10th Business Day in which the Exercise Default continues. In such event,
the Holder shall retain all of the Holder's rights and remedies with respect to
the Company's failure to deliver such Warrant Shares (including without
limitation the right to receive the cash payments specified in subparagraph 3(a)
above).

     (d)  Holder of Record. Each Holder shall, for all purposes, be deemed to
          ----------------
have become the holder of record of Warrant Shares on the Exercise Date of this
Warrant, irrespective of the date of delivery of such Warrant Shares. Nothing in
this Warrant shall be construed as conferring upon the Holder hereof any rights
as a stockholder of the Company prior to the Exercise Date.

     4. Exercise Limitations.

     Notwithstanding anything to the contrary contained herein, this Warrant
shall not be exercisable by the Holder to the extent (but only to the extent)
that, if exercisable by the Holder, the Holder would be the beneficial owner of
more than 4.99%  of the shares of Common Stock. For the purposes of this Section
4, beneficial ownership and all determinations and calculations shall be
determined in accordance with Section 13(d) of the Securities Exchange Act of
1934, as amended, and all applicable rules and regulations thereunder. For
clarification, it is expressly a term of this security that the limitations
contained in this Section 4 shall apply to each successive Holder.  The
restriction contained in this Section 4 may not be altered, amended, deleted or
changed in any manner whatsoever unless the holders of a majority of the
outstanding shares of Common Stock and the Holder hereof approve such
alteration, amendment, deletion or change.

     5. Payment of the Exercise Price.

     The Holder may pay the Exercise Price in either of the following forms or,
at the election of Holder, a combination thereof:

          (a) Cash Exercise: by delivery of immediately available funds.

                                      193
<PAGE>

          (b) Cashless Exercise: by surrender of this Warrant to the Company
together with a notice of cashless exercise, in which event the Company shall
issue to the Holder the number of Warrant Shares determined as follows:

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

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

          Y = the number of Warrant Shares with respect to which this Warrant is
              being exercised.

          A = the average of the Closing Trade Prices (as defined in the
              Securities Purchase Agreement) of the Common Stock for the five
              (5) Trading Days immediately prior to for (but not including) the
              Exercise Price;

          B = the Exercise Price;

provided, however, that the Holder may exercise this Warrant pursuant to a
Cashless Exercise only if, on the Exercise Date, the resale of Warrant Shares is
not covered by an effective registration statement under the Securities Act of
1933, as amended, that is available to the Holder on such date.

     For purposes of Rule 144 under the Securities Act of 1933, as amended, it
is intended, understood and acknowledged that the Warrant Shares issued in a
cashless exercise transaction shall be deemed to have been acquired by the
Holder, and the holding period for the Warrant Shares shall be deemed to have
been commenced, on the Issue Date.

     6. Anti-Dilution Adjustments; Distributions; Other Events.

     The Exercise Price and the number of Warrant Shares issuable hereunder
shall be subject to adjustment from time to time as provided in this Section 6.
In the event that any adjustment of the Exercise Price or number of Warrant
Shares as required herein results in a fraction of a cent or fraction of a
share, as applicable, such exercise Price or number of Warrant Shares shall be
rounded up or down to the nearest cent or share, as applicable.

     (a) Issuance of Other Securities.  If, at any time before the exercise of
         ----------------------------
this Warrant, the Company shall issue any Common Stock, whether upon the
exercise of rights, warrants, securities convertible or exercisable into Common
Stock or otherwise, at a price that is lower than the Exercise Price in effect,
such Exercise Price shall be reduced to such lower price.  Further, if the
Company shall issue any securities which are

                                      194
<PAGE>

convertible into or exchangeable for Common Stock or represent the right to
purchase Common Stock with a fixed conversion or exercise price less than the
Exercise Price then in effect, the Exercise Price shall be reduced to such lower
price. No adjustment to the Exercise Price will be made (i) upon the exercise or
conversion of any warrants, options or convertible securities issued and
outstanding on the date hereof 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, consultant or director
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 majority of non-
employee members 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.

     (b)  Subdivision or Combination of Common Stock. If the Company, at any
          ------------------------------------------
time after the initial issuance of this Warrant, 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 initial issuance of this Warrant, 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 proportionally increased.
In the event of any adjustment to the Exercise Price arising from an event
specified in this paragraph (c), the number of shares of Common Stock into which
this Warrant is exercisable will be proportionately increased or reduced, as the
case may be.

     (c)  Distributions. If the Company or any of its subsidiaries shall at any
          -------------
time distribute to holders of Common Stock (or to a holder, other than the
Company, of the common stock of any such subsidiary) cash, evidences of
indebtedness or other securities or assets (other than cash dividends or
distributions payable out of earned surplus or net profits for the current or
the immediately preceding year) including any dividend or distribution in shares
of capital stock of a subsidiary of the Company (collectively, a "Distribution")
                                                                  ------------
then, in any such case, the Holder of this Warrant shall be entitled to receive,
at the same time as such assets are received by a holder of such stock, an
amount and type of such Distribution as though such Holder were a holder on the
record date therefor of a number of shares of Common Stock into which this
Warrant is exercisable as of such record date (such number of shares to be
determined at the Exercise Price then in effect and without regard to any
limitation on exercise of this Warrant that may exist pursuant to the terms
hereof or otherwise).

     (d)  Additional Shares, Securities or Assets.  In the event that at any
          -----------------  --------------------
time, as a result of an adjustment made pursuant to this Section 6, the Holder
of this Warrant shall, upon exercise of this Warrant, become entitled to receive
securities or assets (other than Common Stock) then, wherever appropriate, all
references herein to shares of Common Stock shall be deemed to refer to and
include such shares and/or other securities or assets; and thereafter the number
of such shares and/or other securities or assets shall be subject

                                      195
<PAGE>

to adjustment from time to time in a manner and upon terms as nearly equivalent
as practicable to the provisions of this Section 6.

     (e)  Special Adjustment and 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, which notice
shall state the Exercise Price resulting from such adjustment and the increase
or decrease in the number of Warrant Shares purchasable at such price upon
exercise, 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.  If the Company takes any actions
(including under or by virtue of this Section 6) which would have a dilutive
effect on the Holder or which would materially and adversely affect the Holder
with respect to its investment in the Warrant, and if the provisions of  this
Section 6, are not strictly applicable to such actions or, if applicable to such
actions, would not operate to equitably protect the Holder against such actions,
then the Company shall promptly upon notice from Holder appoint its independent
certified public accountants to determine as promptly as practicable an
appropriate adjustment to the terms hereof, including without limitation
adjustments to the Exercise Price, or another appropriate action to so equitably
protect such Holder and prevent any such dilution and any such material adverse
effect, as the case may be.  Following such determination, the Company shall
forthwith make the adjustments or take the other actions described therein.

     (f)  Other Notices.  In case at any time:
          -------------

          (i)   the Company shall declare any dividend upon the Common Stock
payable in shares of stock of any class or make any other distribution to the
holders of the Common Stock;

          (ii)  the Company shall offer for subscription pro rata to the holders
of the Common Stock any additional shares of stock of any class or other rights;

          (iii) there shall be any capital reorganization of the Company, or
reclassification of the Common Stock, or consolidation or merger of the Company
with or into, or sale of all or substantially all of its assets to, another
corporation or entity; or

          (iv)  there shall be a voluntary or involuntary dissolution,
liquidation or winding-up of the Company;

then, in each such case, the Company shall give to the Holder (a) notice of the
date on which the books of the Company shall close or a record shall be taken
for determining the holders of Common Stock entitled to receive any such
dividend, distribution, or subscription rights or for determining the holders of
Common Stock entitled to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up and (b) in the case of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation or winding-up, notice of
the date (or, if not then known, a reasonable approximation thereof by the
Company)

                                      196
<PAGE>

when the same shall take place. Such notice shall also specify the date on which
the holders of Common Stock shall be entitled to receive such dividend,
distribution, or subscription rights or to exchange their Common Stock for stock
or other securities or property deliverable upon such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation, or
winding-up, as the case may be. Such notice shall be given at least thirty (30)
days prior to the record date or the date on which the Company's books are
closed in respect thereto, but in no event earlier than public announcement of
such proposed transaction or event. Failure to give any such notice or any
defect therein shall not affect the validity of the proceedings referred to in
clauses (i), (ii), (iii) and (iv) above.

     7. Fractional Interests.

     No fractional shares or scrip representing fractional shares shall be
issuable upon the exercise of this Warrant, but on exercise of this Warrant, the
Holder hereof may purchase only a whole number of shares of Common Stock. If, on
exercise of this Warrant, the Holder hereof would be entitled to a fractional
share of Common Stock or a right to acquire a fractional share of Common Stock,
such fractional share shall be disregarded and the number of shares of Common
Stock issuable upon exercise shall be rounded up or down to the nearest whole
number of shares of Common Stock.

     8. Transfer of this Warrant.

     The Holder may sell, transfer, assign, pledge or otherwise dispose of this
Warrant, in whole or in part, as long as such sale or other disposition is made
pursuant to an effective registration statement or an exemption to the
registration requirements of the Securities Act of 1933, as amended, and
applicable state laws. Upon such transfer or other disposition, the Holder shall
deliver a written notice to Company, substantially in the form of the Transfer
Notice attached hereto as Exhibit B (the "Transfer Notice"), indicating the
                                          ---------------
person or persons to whom this Warrant shall be transferred and, if less than
all of this Warrant is transferred or this Warrant is transferred in parts, the
number of Warrant Shares to be covered by the part of this Warrant to be
transferred to each such person. Within three (3) Business Days of receiving a
Transfer Notice and the original of this Warrant, the Company shall deliver to
the each transferee designated by the Holder a Warrant or Warrants of like tenor
and terms for the appropriate number of Warrant Shares. Notwithstanding the
foregoing, no Holder may knowingly and voluntarily sell this Warrant (or any
portion thereof) to an entity that is a competitor of the Company.

     9. Benefits of this Warrant.

       Nothing in this Warrant shall be construed to confer upon any person
other than the Holder of this Warrant any legal or equitable right, remedy or
claim under this Warrant and this Warrant shall be for the sole and exclusive
benefit of the Holder of this Warrant.

                                      197
<PAGE>

     10. Loss, theft, destruction or mutilation of Warrant.

       Upon receipt by the Company of evidence of the loss, theft, destruction
or mutilation of this Warrant, and (in the case of loss, theft or destruction)
of indemnity or security reasonably satisfactory to the Company, and upon
surrender of this Warrant, if mutilated, the Company shall execute and deliver a
new Warrant of like tenor and date.

     11. Notice or Demands.

       Except as otherwise provided herein, any notice, demand or request
required or permitted to be given pursuant to the terms of this Warrant shall be
in writing and shall be deemed given (i) when delivered personally or by
verifiable facsimile transmission (with an original to follow) on or before 5:00
