exchange of this Warrant) shall have received or, on or after the record date
fixed for the determination of eligible stockholders, shall have become entitled
to receive, without payment therefor, other additional securities or other

receivable thereupon, and without payment of any additional consideration
therefor, the amount of such other or additional securities or other property
(other than regular cash dividends) which such holder would hold on the date of
such exercise or exchange had he been the holder of record of such Shares on the
date hereof and had thereafter, during the period from the date hereof to and
including the date of such exercise or exchange, retained such Shares and/or all
other additional securities or other property receivable by him as aforesaid
during such period, giving effect to all adjustments called for during such

or exchange hereof at any time after the consummation of such reclassification
or change, shall be entitled to receive, in lieu of the stock or other
securities and property receivable upon the exercise or exchange hereof prior to
such consummation, the stock or other securities or property to which such
holder would have been entitled upon such consummation if such holder had
exercised or exchanged this Warrant immediately prior thereto, all subject to
further adjustment as provided in this Section 2.

          2.3  Capital Reorganization; Merger or Sale of Assets.  If at any time

transactions (any of which events is herein referred to as a "Reorganization"),
then as a part of such Reorganization, provision shall be made so that the
Holder, upon the exercise or exchange hereof at any time on or after the
consummation of such Reorganization, shall be entitled to receive, in lieu of
the stock or other securities and property receivable upon the exercise or
exchange hereof, the number of shares of stock or other securities or property
of the Company, or of the successor corporation resulting from such
Reorganization, to which such Holder would have been entitled if such Holder had
exercised or exchanged this Warrant immediately prior thereto, all subject to
further adjustment as set forth in this Section 2.  In any such case,
appropriate adjustment shall be made in the application of the provisions of

               -------------------------------------
time to time on or after the date hereof the Company shall subdivide or
otherwise change its outstanding shares of Common Stock into a greater number of
shares, the number of shares receivable upon exercise or exchange of this
Warrant shall thereby be proportionately increased; and, conversely, if at any
time and from time to time on or after the date hereof the outstanding number of
shares of Common Stock shall be combined or otherwise changed into a smaller
number of shares, the number of shares receivable upon exercise or exchange of
this Warrant shall thereby be proportionately decreased.

          2.5  Anti-dilution.  Adjustments shall be made on an equitable basis
               -------------
to the number of shares issuable upon exercise or exchange of this Warrant in
proportion to, and at the same time as, the adjustments to the Series B
Conversion Value pursuant to Section 4(d) of the Second Amended and Restated
Articles of Incorporation of the Company (the "Articles of Incorporation").  The
provisions of this Section 2.5 shall terminate upon the conversion of more than
50% of the issued Series B Preferred Stock under the Articles of Incorporation

equal to the product of such fraction multiplied by the Fair Market Value
(defined below) of one share of Common Stock on the date of exercise or
exchange.

     4.   No Shareholder Rights.  This Warrant as such shall not entitle the
          ---------------------
Holder to any of the rights of a shareholder of the Company until the Holder has
exercised or exchanged this Warrant in accordance with Section 6 or Section 7
hereof.

     5.   Reservation of Stock.  The Company covenants that during the period
          --------------------
this Warrant is exercisable, the Company will reserve a sufficient number of
shares of its authorized and unissued Common Stock or other securities of the
Company from time to time issuable upon the exercise or exchange of this Warrant
to provide for the issuance of Shares or other securities upon the exercise or
exchange of this Warrant.  The Company agrees that its issuance of this Warrant
shall constitute full authority to its officers who are charged with the duty of
executing stock certificates to execute and issue the necessary certificates for
Shares or other securities upon the exercise or exchange of this Warrant.

     6.   Exercise of Warrant.  This Warrant may be exercised, in whole or in
          -------------------
part, by the Holder by the surrender of this Warrant at the principal office of
the Company, accompanied by notice of and payment in full of the purchase price
of the Shares the Holder elects to purchase hereunder.  This Warrant shall be
deemed to have been exercised immediately prior to the close of business on the
date of its surrender for exercise as provided above, and the person entitled to

                                       3
<PAGE>

receive the Shares or other securities and/or property issuable upon such
exercise shall be treated for all purposes as the holder of such Shares or other
securities of record as of the close of business on such date.  As promptly as
practicable, the Company shall issue and deliver to (or, if so requested at the
time of surrender of this Warrant, hold for pick-up at its principal office by)
the person or persons entitled to receive the same a certificate or certificates
for the number of full Shares or other securities issuable upon such exercise,
together with cash in lieu of any fraction of a share as provided above.  The
Shares or other securities issuable upon exercise hereof shall, upon their
issuance, be fully paid and nonassessable and free and clear of all liens,
security interests or other encumbrances.  If this Warrant shall be exercised in
part only, the Company shall, at the time of delivery of the certificate
representing the Shares or other securities in respect of which this Warrant has
been exercised, deliver to the Holder a new Warrant evidencing the right to
purchase the remaining Shares or other securities purchasable under this
Warrant, which new warrant shall, in all other respects, be identical to this
Warrant.  The Company shall pay any and all documentary, stamp or similar issue
or transfer taxes payable in respect of the issue or delivery of the Shares to
the Holder.

     7.   Right to Exchange Warrant for Stock.
          -----------------------------------

          7.1  Right to Exchange.  In addition to and without limiting the
               -----------------
rights of the Holder under the terms of this Warrant, but subject to the
provisions of Section 1.2, the Holder shall be entitled to exchange this Warrant
or any portion hereof for Shares as provided in this Section 7.  Upon exchange
of this Warrant (the "Exchange") with respect to a particular number of Shares
subject to this Warrant (the "Exchange Warrant Shares"), the Company shall
deliver to the Holder (without payment by the Holder of any cash or other
consideration other than shares of Common Stock in the case of clause (i) of the
first sentence of Section 7.2) that number of Shares equal to the quotient
obtained by dividing (x) the value of this Warrant (or the specified portion
hereof) on the Exchange Date (as defined in Section 7.2 hereof), which value
shall be equal to the aggregate Fair Market Value of the Exchange Warrant Shares
issuable upon exchange of this Warrant (or the specified portion hereof) on the
Exchange Date minus, in the case of clause (ii) of the first sentence of Section
7.2, the aggregate Warrant Price of the Exchange Warrant Shares immediately
prior to the exercise of the Exchange by (y) the Fair Market Value of one Share
on the Exchange Date (as herein defined).  No fractional shares shall be
issuable upon the Exchange, and if the number of shares to be issued determined
in accordance with the foregoing formula is other than a whole number, the
Company shall pay to the Holder an amount in cash equal to the Fair Market Value
of the resulting fractional share on the Exchange Date.

          7.2  Method of Exchange.  The Exchange may be accomplished by the
               ------------------
Holder by the surrender of this Warrant at the principal office of the Company
(the date of such surrender, the "Exchange Date") together with a written
statement specifying that the Holder thereby intends to exchange the Warrant for
Common Stock, indicating the number of shares subject to this Warrant that are
being surrendered (referred to in Section 7.1 hereof as the Exchange Warrant
Shares) pursuant to such Exchange and specifying whether the Holder has elected
to (i) pay an exchange price in shares of Common Stock owned by the Holder (in
which case the Holder shall surrender a number of shares having a Fair Market
Value equal to the

                                       4
<PAGE>

aggregate Warrant Price of the Exchanged Warrant Shares) or (ii) not pay any
exchange price. Certificates for the Shares issuable upon an Exchange (or any
other securities deliverable in lieu thereof under Section 2) shall be issued as
of the Exchange Date and shall be delivered to the Holder immediately following
the Exchange Date.

          7.3  Exchange.  This Warrant shall be deemed to have been exchanged
               --------
immediately prior to the close of business on the date of its surrender for
exchange as provided above, and the person entitled to receive the Shares or
other securities and/or property issuable upon such exchange shall be treated
for all purposes as the holder of such Shares or other securities of record as
of the close of business on such date.  As promptly as practicable, the Company
shall issue and deliver to (or, if so requested at the time of surrender of this
Warrant, hold for pick-up at its principal office by) the person or persons
entitled to receive the same a certificate or certificates for the number of
full Shares or other securities issuable upon such exchange, together with cash
in lieu of any fraction of a share as provided above.  The Shares or other
securities issuable upon exchange hereof shall, upon their issuance, be fully
paid and nonassessable and free and clear of all liens, security interests or
other encumbrances.  If this Warrant shall be exchanged in part only, the
Company shall, at the time of delivery of the certificate representing the
Shares or other securities in respect of which this Warrant has been exchanged,
deliver to the Holder a new Warrant evidencing the right to purchase the
remaining Shares or other securities purchasable under this Warrant, which new
warrant shall, in all other respects, be identical to this Warrant.  The Company
shall pay any and all documentary, stamp or similar issue or transfer taxes
payable in respect of the issue or delivery of the Shares to the Holder.

financial plan objectives have been achieved, together with a detailed
description of the facts and calculations upon which such determination was
based, no later than the earliest of (i) the 45th day following the end of

               ------------------------------------------
the Company is entitled pursuant to Section 8.1 to decrease the number of Shares

     9.   Notice of Proposed Transfers.  This Warrant and the Shares may be
          ----------------------------
transferred and assigned by the Holder subject to the restrictions on transfer
set forth in the Amended and Restated Shareholders Agreement dated as of the
date hereof by and among the Company, the Holder and the other parties thereto
(the "Shareholders Agreement").  Each certificate evidencing the securities
transferred as above provided shall bear the appropriate restrictive legends set
forth in the Shareholders Agreement for so long as such legend is required
pursuant to the terms of such Agreement.

     10.  Replacement of Warrants.  Upon receipt by the Company of evidence
          -----------------------
reasonably satisfactory to the Company of the loss, theft, destruction or
mutilation of the Warrant, and in the case of any such loss, theft or
destruction of the Warrant, on delivery of an indemnity agreement or security
satisfactory in form and amount to the Company acting reasonably, and
reimbursement to the Company of all reasonable expenses incidental thereto, and
upon surrender and cancellation of the Warrant if mutilated, the Company will
execute and deliver, in lieu thereof, a new Warrant of like tenor.

     11.  Certain Definitions. As used in this Warrant, the following terms,
          -------------------
have the following meanings:

          11.1 "Daily Price" means (1) if the shares of such Common Stock then
are listed and traded on the New York Stock Exchange, Inc. ("NYSE"), the closing
price on such day as reported on the NYSE Composite Transactions Tape; (2) if
the shares of Common Stock then are not listed and traded on the NYSE, the
closing price on such day as reported by the principal national securities
exchange on which the shares are listed and traded; (3) if the shares of Common
Stock then are not listed and traded on any such securities exchange, the last
reported sale price on such day on the National Market of the National
Association of Securities Dealers, Inc. Automated Quotation System ("NASDAQ");
or (4) if the shares of Common Stock

                                       7
<PAGE>

then are not traded on the NASDAQ National Market, the average of the highest
reported bid and lowest reported asked price on such day as reported by NASDAQ.

          11.2 "Fair Market Value", as of a particular date, means (i) with
respect to one share of Common Stock, if the sum of the Daily Prices of (x) all
of the outstanding shares of Common Stock that have been registered pursuant to
a public offering and (y) all of the outstanding shares of Common Stock that are
not held by affiliates of the Company and that may be sold on such date in an
open market transaction without registration, is at least $250 million as of
such date, the average (weighted by daily trading volume) of the Daily Prices,
if any, per share of Common Stock for the 20 consecutive trading days
immediately prior to such date or (ii) in all other events with respect to the
Common Stock, or with respect to any other property or consideration, the fair
market value of such Common Stock or other property or consideration as
determined by two appraisers, one selected by the Board of Directors of the
Company and one selected by the Holder.  No Director who is a Holder or who is
designated by or affiliated with a Holder shall vote on the selection of the
appraiser chosen by the Company.  In the event the Board of Directors or the
Holder fails to appoint an appraiser within a reasonable period of time, the
appraisal shall be undertaken by the remaining single appraiser.  The Fair
Market Value shall be the fair market value (determined in the manner described
above) arrived at by the appraisers within thirty (30) days following the
appointment of the last appraiser to be appointed.  In the event that the two
appraisers agree in good faith on such fair market value within such a period of
time, such agreed value shall be used for these purposes.  If the appraisers
cannot agree, but their valuations are within 10% of each other, the Fair Market
Value shall be the mean of the two valuations.  If the appraisers cannot agree
and the differences in the valuations are greater than 10%, the appraisers shall
select a third appraiser who will calculate fair market value independently
(provided that such calculations shall not be more than the value calculated by
the appraiser selected by the Holder or less than the value calculated by the
appraiser selected by the Board of Directors) and, except as provided in the
next sentence, the Fair Market Value of the shares shall be the mean of the two
fair market values arrived at by the appraisers who are closest in amount.  If
one appraiser's valuations is the mean of the other two valuations, such mean
valuation shall be the Fair Market Value.  In the event that the two original
appraisers cannot agree upon a third appraiser within ten (10) days following
the end of the thirty (30) day period referred to above, then the third
appraiser, which appraiser shall be a nationally recognized investment banking
firm, shall be appointed by the American Arbitration Association in Washington,
D.C.  The expenses of the appraisers will be borne by the Company.

     12.  Amendment.  Any term of this Warrant may be amended with the written
          ---------
consent of the Company and the Holder.  Any amendment effected in accordance
with this Section 12 shall be binding upon the Holder of this Warrant, each
future holder of such Warrant, and the Company.

     13.  Remedies.  In the event of any default or threatened default by the
          --------
Company in the performance of or observance with any of the terms of this
Warrant, it is agreed that remedies at law are not and will not be adequate for
the Holder and that such terms may be specifically enforced by a decree for the
specific performance of any agreement contained herein or by an injunction
against a violation of any of the terms hereof or otherwise.

          ----------------------
herein, the provisions hereof shall inure to the benefit of, and be binding
upon, the successors, assigns, heirs, executors and administrators of the
parties hereto; provided that the Company may not assign its obligations under
this Warrant.

     15.  Entire Agreement.  This Warrant, along with the Articles of
          ----------------
Incorporation, the Purchase Agreement and the Related Agreements (as defined in
the Purchase Agreement) constitutes the full and entire understanding and
agreement among the parties with regard to the subjects hereof and thereof and
supersedes all prior agreements and understanding among them as to such subject
matter.

     16.  Severability.  Any invalidity, illegality or limitation of the
          ------------
enforceability with respect to any party of any one or more of the provisions of
this Warrant, or any part thereof, whether arising by reason of the law of any
such person's domicile or otherwise, shall in no way affect or impair the
validity, legality or enforceability of the remainder of this Warrant with
respect to such party or the validity, legality or enforceability of this
Agreement with respect to any other party.  In case any provision of this
Agreement shall be invalid, illegal or unenforceable, it shall to the extent
practicable, be modified so as to make it valid, legal and enforceable and to
retain as nearly as practicable the intent of the parties, and the validity,
