                    AMENDED AND RESTATED WARRANT CERTIFICATE

                           CHAMPION ENTERPRISES, INC.

                  Champion Enterprises, Inc. (the "Issuer"), a Michigan
corporation, for value received, hereby certifies that Fletcher International,
Ltd., or registered assigns, is entitled to purchase from the Issuer the
Issuable Number of duly authorized, validly issued, fully paid and
non-assessable shares (subject to the net exercise provisions and the
adjustments contained in this Amended and Restated Warrant (the "Warrant") and
in the Agreement between Fletcher International, Ltd. and the Issuer dated as of
March 29, 2002 (the "Main Agreement")) of common stock, par value one dollar
($1.00) per share (the "Common Stock") of the Issuer on a net exercise basis as
set forth in Section 1.1(a) at any time or from time to time prior to 6:30 p.m.,
New York City time, on April 2, 2009 (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.

                  This Warrant amends and restates that certain warrant that was
issued on April 2, 2002 (the "Issuance Date") pursuant to the Main Agreement, is
subject to the terms and conditions thereof and the holder of this Warrant (the
"Holder") is subject to certain restrictions set forth in the Main Agreement and
shall be entitled to certain rights and privileges set forth in the Main
Agreement. This Warrant is the Warrant referred to as the "Warrant" in the Main
Agreement. Capitalized terms used but not otherwise defined herein shall have
the meanings ascribed to them 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.       Exercise of Warrant.

         1.1      Manner of Exercise. This Warrant may be exercised by the
Holder hereof, in whole or in part, but not for less than 250,000 shares of
Common Stock appearing on the face of this Warrant at a time (or such lesser
number of shares which may then constitute the maximum number purchasable), at
any time and from time to time, on any Business Day, by facsimile, 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 second (2nd) Business Day following, and excluding, the date the Warrant
Exercise Notice is delivered (the "Warrant Notice Date"), (ii) at the option of
the Holder, 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 (each, a "Warrant Closing Date") unless the Holder
shall have withdrawn the Warrant Exercise Notice prior to the closing of such
exercise on such Warrant Closing Date by written notice to the Issuer regardless
of whether such conditions have been waived or satisfied.

                  (a)      This Warrant may be exercised on a net exercise basis
         only. The number of shares of Common Stock that the Issuer shall issue
         shall be computed as of the date of the Warrant Exercise Notice using
         the following formula:

                                             X = (N*Y/B)*(A-B)/A

                                    Where:

                                    X = the number of shares to be issued to the
                                    Holder hereof;

                                    N = the number of shares on the face of this
                                    Warrant, not to exceed in the aggregate the
                                    Issuable Number, for which this Warrant is
                                    being exercised as specified in the Warrant
                                    Exercise Notice;

                                    Y = the Stock Purchase Price;

                                    A = the Daily Market Price of one share of
                                    the Common Stock issuable at the date of
                                    such calculation; and

                                    B = the Warrant Price (as defined below) (as
                                    adjusted to the date of such calculation).

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

                  (a)      (1) the representations and warranties made by the
         Issuer in the Main Agreement shall be true and correct as of such
         Warrant Closing Date, except those representations and warranties that
         address matters only as of a particular date, which shall be true and
         correct as of such date; (2) the Issuer shall have complied fully with
         all of the covenants and agreements in the Main Agreement; (3) all
         shares to be issued upon such exercise shall be registered under the
         Securities Act in accordance with the terms of the Main Agreement,
         shall be freely tradable Registered Common Stock and shall be duly
         listed and admitted to trading on the New York Stock Exchange, American
         Stock Exchange or Nasdaq National Market System in accordance with the
         terms of the Main Agreement (unless, with respect to clause (3) only,
         the Holder expressly consents in writing to the issuance of
         unregistered Common Stock for a portion or all of the shares to be
         issued upon such exercise; in such case, the Issuer shall use its best
         efforts to cause to be satisfied this condition in clause (3) for the
         balance of shares to be issued upon such exercise); and 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 (1), (2) and (3).

                  (b)      On such Warrant Closing Date, the Issuer shall have
         delivered to the Holder an opinion of Dykema Gossett PLLC (or such
         other counsel reasonably

                                       2

                                                                    Exhibit 4.21

         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), (f), and subsection (i) of (g)
         of Section 4 of the Main Agreement and to the effect that the offer and
         sale of such Registered Common Stock (as defined below) to such Holder
         do not require registration under the Securities Act.

                  (c)      The issuance of Common Stock shall not cause the
         Issuer to exceed the Maximum Number (as defined in the Main Agreement).

                  (d)      As of such Warrant Closing Date, the Issuer shall
         have delivered to the Holder all Restatement Notices required to be
         delivered following a Restatement, and no Restatement shall have
         occurred on or after the date on which the Warrant Exercise Notice is
         delivered.

The Issuer shall use its best efforts to cause each of the foregoing conditions
to be satisfied at the earliest possible date. If the condition set forth above
in paragraph (a)(3) of this Section 1.2 is not satisfied, (x) Holder shall be
entitled to all remedies available at law or in equity in respect of the
Issuer's failure to issue all of the Registered Common Stock required to be
issued pursuant to this Section 1, and (y) the Issuer, upon the written demand,
from time to time, of Holder, shall issue unregistered Common Stock for a
portion or all of the shares of Common Stock to be issued as set forth in such
written demand and shall use its best efforts to cause such condition to be
satisfied. In such cases, upon satisfaction of the condition set forth in the
above paragraph (a)(3), the Issuer shall deliver written notice to such Holder
of such satisfaction. If such condition is not satisfied or waived prior to the
second (2nd) Business Day following, and excluding, the date the Warrant
Exercise Notice is delivered, then (x) the Holder may, at its sole option, and
at any time, withdraw the Warrant Exercise Notice by written notice to the
Issuer regardless of whether such condition has 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; provided, however, that if Holder shall
not have withdrawn a Warrant Exercise Notice by written notice delivered by the
corresponding Warrant Closing Date, then the Issuer shall place in escrow by 5
p.m., New York City time, on such Warrant Closing Date an amount of cash equal
to one hundred four percent (104%) of the product of (x) the number of shares of
Registered Common Stock due under this Section 1 multiplied by (y) the Daily
Market Price calculated as of such Warrant Notice Date. If such condition is not
satisfied within sixty (60) calendar days after and including such Warrant
Closing Date, the Issuer shall cause the escrow agent to deliver such cash to
Holder in lieu of the Issuer 's obligations to issue stock upon such exercise of
the Warrant; provided, however, that the Holder shall not be obligated to pay
any consideration to exercise the Warrant in order to receive the cash payment
specified immediately above; provided, further, however, that this Warrant shall
be deemed exercised with respect to such number of shares of Registered Common
Stock as was the subject of such Warrant Exercise Notice and due to be issued
under this Section 1.

         1.3      When Exercise Effective. Each exercise of this Warrant shall
be deemed to have been effected immediately prior to 6:30 p.m. (time in effect
in New York City on such date) on the Business 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, however, that such exercise shall not be
deemed effective if at or prior to 6:30 p.m. (time in effect in New York City on
such date) on the Warrant Closing Date the Holder delivers written notice of
withdrawal to the Issuer as set forth in Section 1.2.

         1.4      Delivery of Warrant. 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 20 of the Main Agreement
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 Section 1.1 hereof.

         1.5      Delivery of Stock Certificates, etc. On a Warrant Closing
Date, the Issuer at its expense (including the payment by it of any applicable
issue taxes) shall cause to be issued in the name of and delivered to the Holder
hereof or as such Holder may direct,

                  (a)      via facsimile and at such address specified by the
         Holder via a reputable overnight courier, a delivery notice in the form
         of Exhibit 2 hereto and 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 lieu of any fractional share to
         which such Holder would otherwise be entitled, cash in an amount equal
         to the same fraction of the Daily Market Price per share on the
         Business 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 in the Warrant Exercise Notice upon such
         exercise as provided in Section 1.1.

2.       Adjustment of Common Stock Issuable Upon Exercise.

         2.1      General; Warrant Price. The "Warrant Price" shall initially
equal the Stock Purchase Price described in Section 12.21. The Warrant Price
shall thereafter be adjusted and readjusted from time to time as provided 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
Sections 2, 3 and 4 hereof. Additionally, the Warrant Price shall increase by
seventy-five cents ($0.75) on each anniversary of the date of the Main Agreement
and each such increase shall be adjusted and readjusted as if such increase had
occurred on the date of the Main Agreement and had subsequently been adjusted
and readjusted as provided in 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

                                       4

                                                                    Exhibit 4.21

         pursuant to Section 2.3 or 2.4) without consideration or for a
         consideration per share less than 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;

                           (i)      the numerator of which shall be (1) the
                  number of shares of Common Stock outstanding immediately prior
                  to such issue or sale (on a fully-diluted basis calculated
                  using the treasury method in accordance with generally
                  accepted accounting principles) plus (2) the number of shares
                  of Common Stock which the aggregate consideration received or
                  to be received by the Issuer for the total number of such
                  Additional Shares of Common Stock so issued or sold would
                  purchase at 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 (on a fully-diluted basis calculated using the
                  treasury method in accordance with generally accepted
                  accounting principles),

                  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 of Common Stock 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, provision shall be made
         so that the Holder shall receive upon exercise hereof in addition to
         the number of shares of Common Stock receivable thereupon, the kind and
         amount of securities, cash or other property which the Holder would
         have been entitled to receive had the Holder held the Gross Number of
         shares of Common Stock with respect to such exercise on the date of
         such dividend record date and had the Holder thereafter, during the
         period from the date of such dividend to and including the date of
         exercise, retained such securities, cash or other property receivable
         by the Holder as aforesaid during such period, giving application to
         all adjustments called for during such period under this Warrant.

         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 (other than Options or Convertible Securities that constitute
Excluded 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, in
the case of Options or Convertible Securities with terms described in Section
2.3(b), the date of any change, increase or decrease described in Section
2.3(b)) (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 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;

                  (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 increase 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 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
         purchase by the Issuer and 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 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 amount of cash received by the Issuer plus any expenses
                  paid or incurred by the Issuer or any commissions or
                  compensations paid or discounts or concessions 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) other than cash, be computed at the
                  fair value thereof at the time of such issue or sale, as
                  determined in good faith by an independent appraisal firm of
                  recognized national standing appointed by 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, as determined in
                  good faith by an independent appraisal firm of recognized
                  national standing appointed by 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

                                       8

<PAGE>

                                                                    Exhibit 4.21

                  conversion or exchange of all Options and Convertible
                  Securities underlying such Options and Convertible
                  Securities); and

                  (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.       Business Combinations.

         3.1      Adjustment upon Business Combination. In case the Issuer after
the date of the Main Agreement is party to (i) 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 Parent, Subsidiary or
affiliate, (ii) a sale of all or substantially all of the assets of the Issuer
(on a consolidated basis) in a single transaction or series of related
transactions, (iii) any other transaction or series of related transactions by
the Issuer in which the power to cast the majority of the eligible votes at a
meeting of the Issuer's shareholders at which directors are elected is
transferred to a single entity or group acting in concert, or (iv) a capital
reorganization or reclassification of the Common Stock or Other Securities
(other than a reorganization or reclassification in which the Common Stock or
Other Securities are not converted into or exchanged for cash or other property,
and, immediately after consummation of such transaction,

                                       9
<PAGE>

                                                                    Exhibit 4.21

the shareholders of the Issuer immediately prior to such transaction own the
Common Stock, Other Securities or other voting stock of the Issuer in
substantially the same proportions relative to each other as such shareholders
owned immediately prior to such transaction), then, and in the case of each such
transaction (each of which is referred to herein as "Business Combination"),
proper provision shall be made so that, upon the basis and the terms and in the
manner provided herein, the Holder, upon exercise of all or any part of this
Warrant at any time after the consummation of such Business Combination, shall
be entitled to receive upon such exercise, in lieu of the cash, property, Common
Stock or Other Securities issuable upon such exercise prior to such
consummation, any of the following, as shall be elected, in whole or in part, at
least five (5) Business Days before such consummation (or, if the Holder fails
to so elect, the Holder shall be deemed to have elected (B) below), by the
Holder:

                  (A)      the Common Stock and Other Securities, cash and
         property to which the Holder would have been entitled upon such
         consummation if the Holder had held the Gross Number of shares of
         Common Stock (or Other Securities) immediately prior thereto, adjusted
         as nearly as possible to give effect to the net exercise provisions of
         Section 1.1(a); or

                  (B)      cash in an amount equal to the price of a European
         option determined pursuant to the Black-Scholes formula as computed
         using the Bloomberg Professional Service for the Gross Number of shares
         of Common Stock (or Other Securities) with respect to exercise of the
         portion of the Warrant for which this clause (B) is elected, using the
         following variables: (i) the "current price" shall be the closing price
         per share for the Common Stock (or Other Securities) as reported by the
         Bloomberg Professional Service for the primary exchange or quotation
         system on which such Common Stock (or Other Securities) traded on the
         Business Day immediately before the date such Business Combination was
         consummated; (ii) the "strike price" shall be the Warrant Price as of
         the Business Day immediately before the date such Business Combination
         was consummated; (iii) the "interest rate" shall be the yield to
         maturity for a U.S. Treasury security with a time to maturity
         equivalent to the time between the Business Day immediately before the
         date such Business Combination was consummated and the Termination
         Date; (iv) "volatility" shall be equal to seventy-five percent (75%) of
         the number reported by the Bloomberg Professional Service for the
         260-Business-Day period as of the date that is five (5) Business Days
         before and excluding the date such Business Combination was announced
         (but in no event shall the "volatility" be greater than seventy-five
         percent (75%)); (v) the "expiration date" shall be the Termination
         Date; (vi) "trading date" shall be the Business Day immediately before
         the date such Business Combination was consummated; and (vii) "dividend
         yield" shall be zero percent (0%). The Holder shall not be obligated to
         pay any consideration (including, but not limited to, the Stock
         Purchase Price) in order to receive the consideration specified in this
         clause (B);

         provided, that if the Acquiring Person or its Parent, as the case may
         be, shall combine, subdivide or reclassify its common stock, or shall
         declare any dividend payable in shares of its common stock, or shall
         take any other action of a similar nature affecting such shares, the
         calculations above shall be adjusted to the extent appropriate to
         reflect such

                                       10

<PAGE>

                                                                    Exhibit 4.21

         event, including appropriate adjustments to account for any such event
         that occurs during any of the measurement periods set forth above.

         3.2      Assumption of Obligations. Notwithstanding anything contained
herein or in the Main Agreement to the contrary, the Issuer will not effect any
Business Combination unless the requirements of Section 11 of the Main Agreement
have been met and unless, prior to the consummation thereof, each Person (other
than the Issuer) that may be required to deliver any stock, securities, cash or
property upon exercise of this Warrant as provided herein shall assume, by
written instrument delivered to, and reasonably satisfactory to, the Holder, (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 the
Holder such shares of stock, securities, cash or property as, in accordance with
the foregoing provisions of this Section 3, the Holder may be entitled to
receive, and such Person shall have similarly delivered to the Holder an opinion
of counsel for such Person, which counsel shall be reasonably satisfactory to
the Holder, stating that the rights of the Holder under 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 of the rights
pursuant hereto.

4.       Other Dilutive Events, Restatements.

                  (a)      In case any event shall occur as to which the
         provisions of Sections 2 and 3 are not strictly applicable (including,
         without limitation, the repurchase by the Issuer of Options or
         Convertible Securities) 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 notify the Holder of such
         event and, upon demand by the Holder, 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 the value of the purchase
         rights represented by this Warrant. Such opinion shall include the
         basis for the calculations and conclusions contained therein in
         reasonable detail. Upon 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. Upon written request by Holder, Issuer shall provide
         Holder with reasonable access to such information as may be necessary
         to evaluate the calculations and conclusions contained in such opinion.
         Within twenty (20) Business Days of receiving all such information
         Holder may dispute the conclusions of such opinion by providing a
         written notice of dispute to Issuer, which notice shall include the
         basis for the calculations and conclusions contained therein in
         reasonable detail. If Issuer and Holder are unable to agree to the
         appropriate calculation of such adjustment within ten (10) Business
         Days of such notice from Holder, then an independent
         nationally-recognized firm of certified public accountants selected by
         Holder and reasonably acceptable to Issuer shall be

                                       11

<PAGE>

                                                                    Exhibit 4.21

         appointed to resolve the dispute, and such accountants' decision shall
         be final and binding upon the Issuer and the Holder. The costs of such
         firm of certified public accountants shall be borne by Issuer.

                  (b)      In the event of a Restatement the Warrant Price shall
         equal the corresponding Restatement Purchase Price, if the Restatement
         Purchase Price is lower than the Warrant Price in effect on the date
         ninety (90) calendar days after and excluding such Restatement Date.
         "Restatement Purchase Price" means one hundred and fifty percent (150%)
         of the Average Market Price calculated on the date ninety (90) calendar
         days after and excluding the related Restatement Date. The Issuer shall
         deliver a Restatement Notice to the Holder no later than two (2) days
         after and excluding each Restatement Date.

5.       No 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
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 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 but not limited to 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 such Holder a
copy of the most recent report setting forth the Warrant Price in effect as of
the date such report is delivered and showing in reasonable detail how it was
calculated. The Issuer will also keep

                                       12

<PAGE>

                                                                    Exhibit 4.21

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 :

                  (a)      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

                  (b)      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

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

the Issuer will mail to the Holder 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
delivered to Holder at least ten (10) Business Days prior to the date therein
specified, but in no event later than the date notice is delivered to any holder
of Common Stock.

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 required to
permit the full exercise of this Warrant (assuming it were exercised in the
manner provided for in Section 1.1(a) hereof). In the event the number of Common
Shares (or other securities) issuable hereunder exceeds the authorized number of
shares of Common Stock (or other securities), the Issuer shall, as soon as is
reasonably possible and in all events within eight (8) Business Days, take all
actions necessary to increase the authorized number, including causing its Board
of Directors to call a special meeting of shareholders, recommend such increase
and not withdraw such recommendation.

9.       Transfer and Assignment.

         9.1      By accepting delivery of this Warrant Certificate, the

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

(ii) a written agreement of the transferee to comply with the terms of this
Warrant Certificate and, solely insofar as it relates to this Warrant, the Main
Agreement; and (iii) a certificate of the Holder or the transferee that such

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.

10.      Lost or Stolen Warrant. In case this Warrant Certificate shall be
mutilated, lost, stolen or destroyed, the Issuer shall issue in exchange and
substitution for and upon cancellation of the mutilated Warrant Certificate, 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 customary indemnity reasonably
satisfactory to the Issuer.

11.      Warrant Agent. The Issuer (and any corporation into which the Issuer is

Warrant Agent shall be a corporation doing business and in good standing under

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

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

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
