WARRANT NO. W-1                                1,900,000 SHARES OF COMMON STOCK

                               WARRANT CERTIFICATE

                             Newpark Resources, Inc.

         Newpark Resources, Inc. (the "Issuer"), a Delaware corporation, for
value received, hereby certifies that Fletcher International Limited, or
registered assigns, is entitled to purchase from the Issuer 1,900,000 duly
authorized, validly issued, fully paid and nonassessable shares of common stock,
par value $0.01 per share (the "Common Stock") of the Issuer at the purchase
price per share of $10.075, at any time or from time to time prior to 12:01
A.M., New York City time, on June 1, 2007 (or such later date as may be
determined pursuant to the terms hereof) (the "Termination Date"), all subject
to the terms, conditions and adjustments set forth below in this Warrant.


1. Exercise of Warrant. The Warrant represented hereby was issued on June 1,
2000 pursuant to the Agreement between Fletcher International Limited and the
Issuer dated as of May 30, 2000 (the "Main Agreement"), and is subject to the
terms and conditions thereof. Unless otherwise defined herein, capitalized terms
used herein shall have the meanings set forth in the Main Agreement. A copy of
the Main Agreement may be obtained by the registered holder hereof upon written
request to the Issuer.

         1.1 Manner of Exercise. This Warrant may be exercised by the holder
hereof, in whole or in part, from time to time, on any Trading Day, by
facsimile,




<PAGE>   2
mail or overnight courier delivery of a notice in substantially the form
attached to this Warrant (or a reasonable facsimile thereof) duly executed by
such holder (a "Warrant Exercise Notice"). The closing of each exercise shall
take place (i) on the third Trading Day following the date the Warrant Exercise
Notice is delivered, (ii) such later date as the conditions set forth in Section
1.2 have been waived or satisfied or (iii) any other date upon which the
exercising holder and the Issuer mutually agree (the "Warrant Closing Date").

         1.2 Conditions to Closing. It shall be a condition of the exercising
holder's obligation to close that each of the following are satisfied, unless
waived by such holder:

                  (a) (i) The representations and warranties made by the Issuer
         in the Main Agreement shall be true and correct as of the Warrant
         Closing Date, except as otherwise disclosed prior to the date of the
         Warrant Exercise Notice to the registered holders of the Warrant either
         in writing directed to them or in a periodic or current report filed
         with the SEC; (ii) the Issuer shall have complied fully with all of the
         covenants and agreements in the Main Agreement; (iii) all shares to be
         issued upon such exercise are duly listed and admitted to trading on
         each securities exchange, if any, on which the Issuer's Common Stock is
         listed; and (iv) such holder shall have received a certificate of the
         Chief Executive Officer or the Chief Financial Officer of the Issuer
         dated such date and to the effect of clauses (i), (ii) and (iii).

                  (b) On the Warrant Closing Date, the Issuer shall have
         delivered to the holder an opinion of Ervin, Cohen & Jessup LLP (or
         such other counsel reasonably satisfactory to such holder) reasonably
         satisfactory to such holder, dated the date of delivery, confirming in
         substance the matters covered in paragraphs (a), (b), (c), (d), (e) and
         (f) of Section 3 of the Main Agreement, subject to any changes required
         to reflect exceptions referred to in clause (a)(i) above.

                  (c) On the Warrant Closing Date, all shares to be issued upon
         such exercise shall be duly listed and admitted for trading on the New
         York Stock Exchange, if the Issuer's Common Stock is so listed.

The Issuer shall use commercially reasonable efforts to cause each of the
foregoing conditions to be satisfied at the earliest possible date. If such
conditions are not satisfied or waived prior to the third Trading Day following
the date the Warrant Exercise Notice is delivered, then the holder may, at its
sole option, and at any time, withdraw the Warrant Exercise Notice by written
notice to the Issuer regardless of





                                       2
<PAGE>   3
whether such conditions have been satisfied or waived as of the withdrawal date
and, after such withdrawal, shall have no further obligations with respect to
such Warrant Exercise Notice and may submit a Warrant Exercise Notice on any
future date with respect to the shares referenced in the original Warrant
Exercise Notice. Withdrawal of such Warrant Exercise Notice shall be the
exercising holder's sole remedy for the Issuer's failure to cause such
conditions to be satisfied, except to the extent that such failure constitutes a
breach of the provisions of the Main Agreement.

         1.3 When Exercise Effective. Each exercise of this Warrant shall be
deemed to have been effected immediately prior to the close of business on the
Trading Day on which the Warrant Exercise Notice is delivered as provided in
Section 1.1, and at such time the Person or Persons in whose name or names any
certificate or certificates for shares of Common Stock (or Other Securities)
shall be issuable upon such exercise as provided in Section 1.4 shall be deemed
to have become the holder or holders of record thereof. Provided that such
exercise shall not be deemed effective if and as of the date that the holder
delivers written notice of withdrawal to the Issuer as set forth in Section 1.2.

         1.4 Delivery of Warrant and Payment. On the Warrant Closing Date, the
registered holder shall surrender this Warrant Certificate to the Issuer at the
address set forth for notices to the Issuer in Section 19 of the Main Agreement
and shall deliver payment in cash, by wire transfer to the Issuer's account
designated in Section 19 of the Main Agreement of immediately available funds or
by certified or official bank check payable to the order of the Issuer, or in
the manner provided in Section 6(c)(x) or Section 6(c)(y) of the Main Agreement
in the amount obtained by multiplying (a) the number of shares of Common Stock
(without giving effect to any adjustment thereof) designated in such notice by
(b) $10.075, and such holder shall thereupon be entitled to receive the number
of duly authorized, validly issued, fully paid and nonassessable shares of
Common Stock (or Other Securities) determined as provided in Sections 2, 3 and
4.

         1.5 Delivery of Stock Certificates, etc. On the Warrant Closing Date,
the Issuer at its 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 holder may direct,

                  (a) at such address specified by the holder via reputable
         overnight courier, one or more certificates for the number of duly
         authorized, validly issued, fully paid and nonassessable shares of
         Common Stock (or Other Securities) to which such holder shall be
         entitled upon such exercise plus, in





                                       3
<PAGE>   4

         lieu of any fractional share to which such holder would otherwise be
         entitled, cash in an amount equal to the same fraction of the Market
         Price per share on the Trading Day next preceding the date of such
         exercise, and

                  (b) in case such exercise is in part only, at such address
         specified by the holder via reputable overnight courier, a new Warrant
         of like tenor, calling in the aggregate on the face or faces thereof
         for the number of shares of Common Stock equal (without giving effect
         to any adjustment thereof) to the number of such shares called for on
         the face of this Warrant minus the number of such shares designated by
         the holder upon such exercise as provided in Section 1.1.

2. Adjustment of Common Stock Issuable Upon Exercise.

         2.1 General; Warrant Price. The number of shares of Common Stock which
the holder of this Warrant shall be entitled to receive upon each exercise
hereof shall be determined by multiplying the number of shares of Common Stock
which would otherwise (but for the provisions of Section 2, 3 and 4) be issuable
upon such exercise, as designated by the holder hereof pursuant to Section 1.1,
by the fraction of which (a) the numerator is $10.075 and (b) the denominator is
the Warrant Price in effect on the date of such exercise. The "Warrant Price"
shall initially be $10.075 per share, shall be adjusted and readjusted from time
to time as provided in the Main Agreement or in Sections 2, 3 and 4 hereof and,
as so adjusted or readjusted, shall remain in effect until a further adjustment
or readjustment thereof is required by the Main Agreement or by Sections 2, 3
and 4 hereof.

         2.2 Adjustment of Warrant Price.

                  (a) Issuance of Additional Shares of Common Stock. In case the
         Issuer at any time or from time to time after the date hereof shall
         issue or sell Additional Shares of Common Stock (including Additional
         Shares of Common Stock deemed to be issued pursuant to Section 2.3 or
         2.4) without consideration or for a consideration per share less than
         the greater of the Market Price and the Warrant Price in effect
         immediately prior to such issue or sale, then, and in each such case,
         subject to Section 2.8, such Warrant Price shall be reduced,
         concurrently with such issue or sale, to a price (calculated to the
         nearest .001 of a cent) determined by multiplying such Warrant Price by
         a fraction;




                                       4
<PAGE>   5
                           (i) the numerator of which shall be (1) the number of
                  shares of Common Stock outstanding immediately prior to such
                  issue or sale plus (2) the number of shares of Common Stock
                  which the aggregate consideration received by the Issuer for
                  the total number of such Additional Shares of Common Stock so
                  issued or sold would purchase at the greater of such Market
                  Price and such Warrant Price, and

                           (ii) the denominator of which shall be the number of
                  shares of Common Stock outstanding immediately after such
                  issue or sale,

provided that, for the purposes of this Section 2.2(a) (x) immediately after any
Additional Shares of Common Stock are deemed to have been issued pursuant to
Section 2.3 or 2.4, such Additional Shares shall be deemed to be outstanding,
and (y) treasury shares shall not be deemed to be outstanding.

                  (b) Dividends and Distributions. In case the Issuer at any
         time or from time to time after the date hereof shall declare, order,
         pay or make a dividend or other distribution (including, without
         limitation, any distribution of other or additional stock or other
         securities or property or Options by way of dividend or spin-off,
         reclassification, recapitalization or similar corporate rearrangement)
         on the Common Stock, other than a dividend payable in Additional Shares
         of Common Stock, then, subject to Section 2.8, the Warrant Price in
         effect immediately prior to the close of business on the record date
         fixed for the determination of holders of any class of securities
         entitled to receive such dividend or distribution shall be reduced,
         effective as of the close of business on such record date, to a price
         (calculated to the nearest .001 of a cent) determined by multiplying
         such Warrant Price by a fraction

                           (i) the numerator of which shall be the Market Price
                  in effect on the Trading Day immediately prior to such record
                  date or, if the Common Stock trades on an ex-dividend basis,
                  on the date prior to the commencement of ex-dividend trading,
                  less the amount of such dividend or distribution (as
                  determined in good faith by the Board of Directors of the
                  Issuer) applicable to one share of Common Stock, and

                           (ii) the denominator of which shall be such Market
                  Price.

         2.3 Treatment of Options and Convertible Securities. In case the Issuer
at any time or from time to time after the date hereof shall issue, sell, grant
or assume, or shall fix a record date for the determination of holders of any
class of securities entitled to receive, any Options or Convertible Securities,
then, and in each such case, the maximum number of Additional Shares of Common
Stock (as set forth in the instrument relating thereto, without regard to any
provisions contained therein for a subsequent adjustment of such number)
issuable upon the exercise of such Options or, in the case of Convertible
Securities and Options therefor, the conversion or exchange of such Convertible
Securities, shall be deemed to be Additional Shares of Common Stock issued as of
the time of such issue, sale, grant or assumption or, in case such a record date
shall have been fixed, as of the close of business on such record date (or, if
the Common Stock trades on an ex-dividend basis, on the date prior to the
commencement of ex-dividend trading), provided that such Additional Shares of
Common Stock shall not be deemed to have been issued unless the consideration
per share (determined pursuant to Section 2.5) of such shares would be less than
the greater of the Market Price and the Warrant Price in effect on the date of
and immediately prior to such issue, sale, grant or assumption or immediately
prior to the close of business on such record date (or, if the Common Stock
trades on an ex-dividend basis, on the date prior to the commencement of
ex-dividend trading), as the case may be, and provided, further, that in any
such case in which Additional Shares of Common Stock are deemed to be issued

                  (a) no further adjustment of the Warrant Price shall be made
         upon the subsequent issue or sale of Convertible Securities or shares
         of Common Stock upon the exercise of such Options or the conversion or
         exchange of such Convertible Securities, except in the case of any such
         Options or Convertible Securities which contain provisions requiring
         an adjustment, subsequent to the date of the issue or sale thereof, of
         the number of Additional Shares of Common Stock issuable upon the
         exercise of such Options or the conversion or exchange of such
         Convertible Securities for any reason, each such case to be deemed
         hereunder to involve a separate issuance of Additional Shares of
         Common Stock, Options or Convertible Securities, as the case may be;

                  (b) if such Options or Convertible Securities by their terms
         provide, with the passage of time or otherwise, for any change in the
         consideration payable to the Issuer, or decrease in the number of
         Additional Shares of Common Stock issuable, upon the exercise,
         conversion or exchange thereof (by change of rate or otherwise), the
         Warrant Price computed upon the original issue, sale, grant or
         assumption thereof (or upon the occurrence of the record date, or date
         prior to the commencement of ex-dividend trading, as the





                                       6
<PAGE>   7
         case may be, with respect thereto), and any subsequent adjustments
         based thereon, shall, upon any such increase or decrease becoming
         effective, be recomputed to reflect such increase or decrease insofar
         as it affects such Options, or the rights of conversion or exchange
         under such Convertible Securities, which are outstanding at such time;

                  (c) upon the expiration (or purchase by the Issuer and
         cancellation or retirement) of any such Options which shall not have
         been exercised or the expiration of any rights of conversion or
         exchange under any such Convertible Securities which (or purchase by
         the Issuer and cancellation or retirement of any such Convertible
         Securities the rights of conversion or exchange under which) shall not
         have been exercised, the Warrant Price computed upon the original
         issue, sale, grant or assumption thereof (or upon the occurrence of the
         record date, or date prior to the commencement of ex-dividend trading,
         as the case may be, with respect thereto), and any subsequent
         adjustments based thereon, shall, upon such expiration (or such
         cancellation or retirement, as the case may be), be recomputed as if:

                           (i) in the case of Options for Common Stock or
                  Convertible Securities, the only Additional Shares of Common
                  Stock issued or sold were the Additional Shares of Common
                  Stock, if any, actually issued or sold upon the exercise of
                  such Options or the conversion or exchange of such Convertible
                  Securities and the consideration received therefor was the
                  consideration actually received by the Issuer for the issue,
                  sale, grant or assumption of all such Options, whether or not
                  exercised, plus the consideration actually received by the
                  Issuer upon such exercise, or for the issue or sale of all
                  such Convertible Securities which were actually converted or
                  exchanged, plus the additional consideration, if any, actually
                  received by the Issuer upon such conversion or exchange, and

                           (ii) in the case of Options for Convertible
                  Securities, only the Convertible Securities, if any, actually
                  issued or sold upon the exercise of such Options were issued
                  at the time of the issue, sale, grant or assumption of such
                  Options, and the consideration received by the Issuer for the
                  Additional Shares of Common Stock deemed to have then been
                  issued was the consideration actually received by the Issuer
                  for the issue, sale, grant or assumption of all such Options,
                  whether or not exercised, plus the consideration deemed to
                  have been received by the Issuer (pursuant to Section 2.5)
                  upon the issue or sale




                                       7
<PAGE>   8

                  of such Convertible Securities with respect to which such
                  Options were actually exercised;

                  (d) no readjustment pursuant to subdivision (b) or (c) above
         shall have the effect of increasing the Warrant Price by an amount in
         excess of the amount of the adjustment thereof originally made in
         respect of the issue, sale, grant or assumption of such Options or
         Convertible Securities; and

                  (e) in the case of any such Options which expire by their
         terms not more than 30 days after the date of issue, sale, grant or
         assumption thereof, no adjustment of the Warrant Price shall be made
         until the expiration or exercise of all such Options, whereupon such
         adjustment shall be made in the manner provided in subdivision (c)
         above.

         2.4 Treatment of Stock Dividends, Stock Splits, etc. In case the Issuer
at any time or from time to time after the date hereof shall declare or pay any
dividend on the Common Stock payable in Common Stock, or shall effect a
subdivision of the outstanding shares of Common Stock into a greater number of
shares of Common Stock (by reclassification or otherwise than by payment of a
dividend in Common Stock), then, and in each such case, Additional Shares of
Common Stock shall be deemed to have been issued (a) in the case of any such
dividend, immediately after the close of business on the record date for the
determination of holders of any class of securities entitled to receive such
dividend, or (b) in the case of any such subdivision, at the close of business
on the day immediately prior to the day upon which such corporate action becomes
effective.

         2.5 Computation of Consideration. For the purposes of this Section 2,

                  (a) the consideration for the issue or sale of any Additional
         Shares of Common Stock shall, irrespective of the accounting treatment
         of such consideration,

                           (i) insofar as it consists of cash, be computed at
                  the net amount of cash received by the Issuer, without
                  deducting any expenses paid or incurred by the Issuer or any
                  commissions or compensations paid or concessions or discounts
                  allowed to underwriters, dealers or others performing similar
                  services in connection with such issue or sale,

                           (ii) insofar as it consists of property (including
                  securities)




                                       8
<PAGE>   9
                  other than cash, be computed at the fair value thereof at the
                  time of such issue or sale, as determined in good faith by the
                  Board of Directors of the Issuer, and

                           (iii) in case Additional Shares of Common Stock are
                  issued or sold together with other stock or securities or
                  other assets of the Issuer for a consideration which covers
                  both, be the portion of such consideration so received,
                  computed as provided in clauses (i) and (ii) above, allocable
                  to such Additional Shares of Common Stock, all as determined
                  in good faith by the Board of Directors of the Issuer;

                  (b) Additional Shares of Common Stock deemed to have been
         issued pursuant to Section 2.3, relating to Options and Convertible
         Securities, shall be deemed to have been issued for a consideration per
         share determined by dividing

                           (i) the total amount, if any, received and receivable
                  by the Issuer as consideration for the issue, sale, grant or
                  assumption of the Options or Convertible Securities in
                  question, plus the minimum aggregate amount of additional
                  consideration (as set forth in the instruments relating
                  thereto, without regard to any provision contained therein
                  for a subsequent adjustment of such consideration to protect
                  against dilution) payable to the Issuer upon the exercise in
                  full of such Options or the conversion or exchange of such
                  Convertible Securities or, in the case of Options for
                  Convertible Securities, the exercise of such Options for
                  Convertible Securities and the conversion or exchange of such
                  Convertible Securities, in each case computing such
                  consideration as provided in the foregoing subdivision (a),

by

                           (ii) the maximum number of shares of Common Stock (as
                  set forth in the instruments relating thereto, without regard
                  to any provision contained therein for a subsequent adjustment
                  of such number to protect against dilution) issuable upon the
                  exercise of such Options or the conversion or exchange of such
                  Convertible Securities (including the full conversion or
                  exchange of all Options and Convertible Securities underlying
                  such Options and Convertible Securities); and




                                       9
<PAGE>   10

                  (c) Additional Shares of Common Stock deemed to have been
         issued pursuant to Section 2.4, relating to stock dividends, stock
         splits, etc., shall be deemed to have been issued for no consideration.

         2.6 Adjustments for Combinations, etc. In case the outstanding shares
of Common Stock shall be combined or consolidated, by reclassification or
otherwise, into a lesser number of shares of Common Stock, the Warrant Price in
effect immediately prior to such combination or consolidation shall,
concurrently with the effectiveness of such combination or consolidation, be
proportionately increased.

         2.7 Dilution in Case of Other Securities. In case any Other Securities
shall be issued or sold or shall become subject to issue or sale upon the
conversion or exchange of any stock (or Other Securities) of the Issuer (or any
issuer of Other Securities or any other Person referred to in Section 3) or to
subscription, purchase or other acquisition pursuant to any Options issued or
granted by the Issuer (or any such other issuer or Person) for a consideration
such as to dilute, on a basis consistent with the standards established in the
other provisions of this Section 2, the purchase rights granted by this Warrant,
then, and in each such case, the computations, adjustments and readjustments
provided for in this Section 2 with respect to the Warrant Price shall be made
as nearly as possible in the manner so provided and applied to determine the
amount of Other Securities from time to time receivable upon the exercise of the
Warrant, so as to protect the holder or holders of the Warrant against the
effect of such dilution.

         2.8 Minimum Adjustment of Warrant Price. If the amount of any
adjustment of the Warrant Price required pursuant to this Section 2 would be
less than one tenth (1/10) of one percent (1%) of the Warrant Price in effect at
the time such adjustment is otherwise so required to be made, such amount shall
be carried forward and adjustment with respect thereto made at the time of and
together with any subsequent adjustment which, together with such amount and any
other amount or amounts so carried forward, shall aggregate at least one tenth
(1/10) of one percent (1%) of such Warrant Price.

3. Consolidation, Merger, etc.

         3.1 Adjustments for Consolidation, Merger, Sale of Assets,
Reorganization, etc. In case the Issuer after the date hereof (a) is party to
any acquisition of the Issuer by means of merger or other form of corporate
reorganization in which outstanding shares of the Issuer are exchanged for
securities or other consideration issued, or caused to be issued, by the
Acquiring Person or its subsidiary or affiliate, (b) a sale of all or
substantially all of the assets of the Issuer (on a consolidated





                                       10
<PAGE>   11

basis) (c) any other transaction or series of related transactions in which the
power to cast the majority of the eligible votes at a meeting of the Issuer's
stockholders at which directors are elected is transferred to a single entity or
group acting in concert, or (d) shall effect a capital reorganization or
reclassification of the Common Stock or Other Securities (other than a capital
reorganization or reclassification resulting in the issue of Additional Shares
of Common Stock for which adjustment in the Warrant Price is provided in Section
2.2(a) or 2.2(b), then, and in the case of each such transaction, proper
provision shall be made so that, upon the basis and the terms and in the manner
provided in this Warrant, the holder of this Warrant, upon the exercise hereof
at any time after the consummation of such transaction, shall be entitled to
receive (at the aggregate price payable by such holder in effect at the time of
such consummation for all Common Stock or Other Securities issuable upon such
exercise immediately prior to such consummation), in lieu of the Common Stock
or Other Securities issuable upon such exercise prior to such consummation,
either of the following, as shall be elected, in whole or in part, from time to
time, by such holder:

                           (i) the stock and other securities, cash and property
                  to which such holder would have been entitled upon such
                  consummation if such holder had exercised the rights
                  represented by this Warrant immediately prior thereto, subject
                  to adjustments (subsequent to such corporate action) as nearly
                  equivalent as possible to the adjustments provided for in
                  Section 2 and this Section 3;

                           (ii) the number of shares of common stock of the
                  Acquiring Person or its Parent, at the election of the holder
                  (subject to adjustments, subsequent to such corporate action,
                  as nearly equivalent as possible to the adjustments provided
                  for in Section 2 and this Section 3), determined by dividing
                  (A) the amount equal to the product obtained by multiplying
                  (1) the number of shares of Common Stock (or Other Securities)
                  to which the holder of this Warrant would have been entitled
                  had such holder exercised this Warrant immediately prior to
                  such consummation, times (2) the greater of the Acquisition
                  Price and the Warrant Price in effect on the Trading Day
                  immediately preceding the date of such consummation, by (B)
                  the Market Price per share of the common stock of the
                  Acquiring Person or its Parent, as the case may be, on the
                  Trading Day immediately preceding the date of such
                  consummation; or

                           (iii) cash in an amount equal to 33% of the aggregate
                  Warrant Price of the unexercised portion of the Warrant on the
                  Trading





                                       11
<PAGE>   12
                  Day immediately preceding the date of such consummation,
                  provided, however, (A) that the Issuer shall not under any
                  circumstances be obligated to pay cash to any holder, the
                  Issuer's obligation being limited to the obligation to require
                  any Acquiring Person and its Parent to agree to pay such cash
                  as a condition to consummating any of the transactions
                  described in clauses (a) through (d) of this Section 3.1 and
                  (B) the holder shall not be obligated to pay any consideration
                  to exercise the Warrant in order to receive the cash payment
                  specified in this clause (iii).

         3.2 Assumption of Obligations. Notwithstanding anything contained in
the Warrant or in the Main Agreement to the contrary, the Issuer will not effect
any of the transactions described in clauses (a) through (d) of Section 3.1
unless, prior to the consummation thereof, each Person (other than the Issuer)
which may be required to deliver any stock, securities, cash or property upon
the exercise of this Warrant as provided herein shall assume, by written
instrument delivered to, and reasonably satisfactory to, the holder of this
Warrant, (a) the obligations of the Issuer under this Warrant (and if the Issuer
shall survive the consummation of such transaction, such assumption shall be in
addition to, and shall not release the Issuer from, any continuing obligations
of the Issuer under this Warrant), and (b) the obligation to deliver to such
holder such shares of stock, securities, cash or property as, in accordance with
the foregoing provisions of this Section 3, such holder may be entitled to
receive, and such Person shall have similarly delivered to such holder an
opinion of counsel for such Person, which counsel shall be reasonably
satisfactory to such holder, stating that this Warrant shall thereafter continue
in full force and effect and the terms hereof (including, without limitation,
all of the provisions of this Section 3) shall be applicable to the stock,
securities, cash or property which such Person may be required to deliver upon
any exercise of this Warrant or the exercise of any rights pursuant hereto.
Nothing in this Section 3 shall be deemed to authorize the Issuer to enter into
any transaction not otherwise permitted by Section 10 of the Main Agreement.

4. Other Dilutive Events. In case any event shall occur as to which the
provisions of Sections 2 and 3 are not strictly applicable but the failure to
make any adjustment would not fairly protect the purchase rights represented by
this Warrant in accordance with the essential intent and principles of such
Sections, then, in each such case, the Issuer shall appoint a firm of
independent certified public accountants of recognized national standing (which
shall not be the regular auditors of the Issuer), which shall give their opinion
upon the adjustment, if any, on a basis consistent with the essential intent and
principles established in Sections 2 and 3, necessary to preserve, without
dilution, the purchase rights represented by this Warrant. Upon





                                       12
<PAGE>   13

receipt of such opinion, the Issuer will promptly deliver a copy thereof via
facsimile and overnight courier to the holder or holders of this Warrant and
shall make the adjustments described therein.

5. No Dilution or Impairment. The Issuer will not, by amendment of its
certificate of incorporation or through any consolidation, merger,
reorganization, transfer of assets, 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 of this Warrant, but will at all times in good faith assist
in the carrying out of all such terms and in the taking of all such action as
may be necessary or appropriate in order to protect the rights of the holder of
this Warrant against dilution or other impairment. Without limiting the
generality of the foregoing, the Issuer (a) will not permit the par value of any
shares of stock receivable upon the exercise of this Warrant to exceed the
amount payable therefor upon such exercise, (b) will take all such action as may
be necessary or appropriate in order that the Issuer may validly and legally
issue fully paid and nonassessable shares of stock on the exercise of the
Warrants from time to time outstanding, and (c) will not take any action which
results in any adjustment of the Warrant Price if the total number of shares of
Common Stock (or Other Securities) issuable after the action upon the exercise
of all of the Warrants would exceed the total number of shares of Common Stock
(or Other Securities) then authorized by the Issuer's certificate of
incorporation and available for the purpose of issue upon such exercise.

6. Accountants' Report 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 this Warrant, the Issuer at its expense will promptly compute
such adjustment or readjustment in accordance with the terms of this Warrant and
cause independent certified public accountants of recognized national standing
(which may be the regular auditors of the Issuer) selected by the Issuer to
verify such computation (other than any computation of the fair value of
property as determined in good faith by the Board of Directors of the Issuer)
and prepare a report setting forth such adjustment or readjustment and showing
in reasonable detail the method of calculation thereof and the facts upon which
such adjustment or readjustment is based, including a statement of (a) the
consideration received or to be received by the Issuer for any Additional Shares
of Common Stock issued or sold or deemed to have been issued, (b) the number of
shares of Common Stock outstanding or deemed to be outstanding, and (c) the
Warrant Price in effect immediately prior to such issue or sale and as adjusted
and readjusted (if required by Section 2, 3 or 4) on account thereof. The Issuer
will forthwith mail a copy of each such report to each holder of a Warrant and
will, upon the written request at any time of any holder of a Warrant, furnish
to






                                       13
<PAGE>   14

such holder a like report setting forth the Warrant Price at the time in effect
and showing in reasonable detail how it was calculated. The Issuer will also
keep copies of all such reports at its principal office and will cause the same
to be available for inspection at such office during normal business hours by
any holder of a Warrant or any prospective purchaser of a Warrant designated by
the holder thereof.

7. Notices of Corporate Action. In the event of

         7.1 any taking by the Issuer 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 (other than a regular periodic dividend payable in cash
out of earned surplus in an amount not exceeding the amount of the immediately
preceding cash dividend for such period) 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

         7.2 any capital reorganization of the Issuer, any reclassification or
recapitalization of the capital stock of the Issuer or any consolidation or
merger involving the Issuer and any other Person or any transfer of all or
substantially all the assets of the Issuer to any other Person, or

         7.3 any voluntary or involuntary dissolution, liquidation or winding-up
of the Issuer, the Issuer will mail to each holder of a Warrant a notice
specifying (i) the date or expected date on which any such record is to be taken
for the purpose of such dividend, distribution or right, and the amount and
character of such dividend, distribution or right, and (ii) the date or expected
date on which any such reorganization, reclassification, recapitalization,
consolidation, merger, transfer, dissolution, liquidation or winding-up is to
take place and the time, if any such time is to be fixed, as of which the
holders of record of Common Stock (or Other Securities) shall be entitled to
exchange their shares of Common Stock (or Other Securities) for the securities
or other property deliverable upon such reorganization, reclassification,
recapitalization, consolidation, merger, transfer, dissolution, liquidation or
winding-up. Such notice shall be mailed at least 45 days prior to the date
therein specified.

8. Reservation of Shares. For so long as the Warrant represented hereby has not
been exercised in full, the Issuer shall at all times prior to the Termination
Date reserve and keep available, free from pre-emptive rights, out of its
authorized but unissued capital stock, the number of shares set forth in the
Main Agreement. In the event the number of Common Shares issuable exceeds the
authorized number of




                                       14
<PAGE>   15

shares of Common Stock or other securities, the Issuer shall promptly take all
actions necessary to increase the authorized number, including causing its Board
of Directors to call a special meeting of shareholders and recommend such
increase.

9. Transfer and Assignment.

         9.1 By accepting delivery of this Warrant Certificate, the registered
holder hereof covenants and agrees with the Issuer not to exercise the Warrant
or transfer the Warrant or the Common Shares represented hereby except in
compliance with the terms of the Main Agreement and this Warrant Certificate.

         9.2 By accepting delivery of this Warrant Certificate, the registered
holder hereof covenants and agrees with the Issuer that no Warrant may be sold
or assigned, in whole or in part, unless such sale or assignment complies with
applicable federal and state securities laws and until such holder shall
deliver to the Issuer (i) written notice of such transfer and of the name and
address of the transferee and such notice has been received by the Issuer; (ii)
a written agreement of the transferee to comply with the terms of the Main
Agreement and this Warrant Certificate; and (iii) a certificate of the
transferee and an opinion of counsel reasonably satisfactory to the Issuer that
such transfer complies with applicable federal and state securities laws;
provided, however that nothing in this Warrant Certificate shall limit the right
or ability of the holder to engage in hedging transactions with respect to the
Warrant or the underlying Common Shares. If a portion of the Warrant is
transferred, all rights of the registered holder hereunder may be exercised by
the transferee provided that any registered holder of the Warrant may deliver a
Warrant Exercise Notice only with respect to the Common Shares subject to such
holder's portion of the Warrant.

         9.3 The Issuer will pay all documentary stamp taxes (if any)
attributable to the issuance of Common Shares upon the exercise of the Warrant
by the registered holder hereof; provided, however, that the Issuer shall not be
required to pay any tax or taxes which may be payable in respect of any transfer
involved in the registration of the Warrant Certificate or any certificates for
Common Shares in a name other than that of the registered holder of the Warrant
Certificate surrendered upon the exercise of a Warrant, and the Issuer shall not
be required to issue or deliver the Warrant Certificate or certificates for
Common Shares unless or until the person or persons requesting the issuance
thereof shall have paid to the Issuer the amount of such tax or shall have
established to the reasonable satisfaction of the Issuer that such tax has been
paid.




                                       15

10. Lost or Stolen Warrant. In case this Warrant Certificate shall be mutilated,
lost, stolen or destroyed, the Issuer may in its discretion issue in exchange
and substitution for and upon cancellation of the mutilated Warrant Certificate,
or in lieu of and substitution for the Warrant Certificate lost, stolen or
destroyed, a new Warrant Certificate of like tenor, but only upon receipt of
evidence reasonably satisfactory to the Issuer of such loss, theft or
destruction of such Warrant Certificate and indemnity, if requested, reasonably
satisfactory to the Issuer. Applicants for a substitute Warrant Certificate
shall also comply with such other reasonable regulations and pay such other
reasonable charges as the Issuer may prescribe.

11. Warrant Agent. The Issuer (and any corporation into which the Issuer is
merged or any corporation resulting from any consolidation to which the Issuer
is a party) shall serve as warrant agent (the "Warrant Agent") under this
Warrant. The Warrant Agent hereunder shall at all times maintain a register (the
"Warrant Register") of the holders of Warrant. Upon 30 days' notice to the
registered holder hereof, the Issuer may appoint a new Warrant Agent. Such new
Warrant Agent shall be a corporation doing business and in good standing under
the laws of the United States or any state thereof, and having a combined
capital and surplus of not less than $100,000,000. The combined capital and
surplus of any such new Warrant Agent shall be deemed to be the combined capital
and surplus as set forth in the most recent report of its condition published by
such Warrant Agent prior to its appointment; provided that such reports are
published at least annually pursuant to law or to the requirements of a federal
or state supervising or examining authority. After acceptance in writing of
such appointment by the new Warrant Agent, it shall be vested with the same
powers, rights, duties and responsibilities as if it had been originally named
herein as the Warrant Agent, without any further assurance, conveyance, act or
deed; but if for any reason it shall be reasonably necessary or expedient to
execute and deliver any further assurance, conveyance, act or deed, the same
shall be done at the expense of the Issuer and shall be legally and validly
executed and delivered by the Issuer. Any corporation into which any new Warrant
Agent may be merged or any corporation resulting from any consolidation to which
any new Warrant Agent shall be a party or any corporation to which any new
Warrant Agent transfers substantially all of its corporate trust or shareholders
services business shall be a successor Warrant Agent under this Warrant without
any further act; provided that such corporation (i) would be eligible for
appointment as successor to the Warrant Agent under the provisions of this
Section 11 or (ii) is a wholly owned subsidiary of the Warrant Agent. Any such
successor Warrant Agent shall promptly cause notice of its succession as Warrant
Agent to be delivered via reputable overnight courier to the registered holder
hereof at such holder's last address as shown on the Warrant Register.
