Maximum Ownership Percentage as a result of a reduction in the number of
Voting Securities outstanding (including, without limitation, as a result of
a purchase of Common Stock by the Company) (such excess, the "BUY-BACK
EXCESS"), then the Shareholder shall, or shall cause the Shareholder Group
to, consistent with the provisions of this Agreement, promptly (in any event,
prior to the earliest to occur of (x) the record date for the next annual or
special meeting of shareholders of the Company, (y) the record date for the
taking of any action of shareholders of the Company by written consent or (z)
the purchase of any additional Voting Securities by any member of the
Shareholder Group) take all action necessary to reduce the amount of Voting
Securities Beneficially Owned by the Shareholder Group by the amount of such
Buy-Back Excess in the following manner and order:

                     (i)   First, for purposes of clauses (ii) and (iii)
        below, the Buy Back Excess shall be reduced by the amount, if any,
        of Voting Securities received by the PepsiCo Group as an Aggregate
        Contingent Payment (as defined in the Merger Agreement), to the
        extent such Aggregate Contingent Payment has not been previously
        used to reduce the Buy-Back Excess pursuant to this Section.

                     (ii)  Second, by Transferring to a Person other than the
        Significant Shareholders the pro rata amount (based on the relative
        amounts of Voting Securities purchased by each of the Shareholder
        Group and the PepsiCo Group since August 18, 2000) of Voting
        Securities, if any, purchased by the Shareholder Group since August
        18, 2000;

                   (iii) Third, by Transferring to a Person other than the
        Significant Shareholders the pro rata amount of any remaining
        Buy-Back Excess (based on the relative Total Ownership Percentages,
        after giving effect to (i) and (ii) above,

                                      -8-

<PAGE>

          of the Shareholder Group and the PepsiCo Group immediately prior to
          the time when the Combined Maximum Ownership Percentage was exceeded).

                     (iv) Fourth, notwithstanding the foregoing, the maximum
          number of Voting Securities that the Shareholder Group shall be
          required to Transfer pursuant to (ii) and (iii) above shall not
          exceed the amount that would be required to be Transferred if the
          PepsiCo Group made its corresponding pro rata Transfers consistent
          with (ii) and (iii) above.

          (c)  If at any time the Shareholders become aware that the
Significant Shareholders' Total Ownership Percentage exceeds the Combined
Maximum Ownership Percentage, other than as a result of a reduction in the
total number of Voting Securities (which situation shall be governed by
paragraph (b) above) or as permitted pursuant to the terms of this Agreement,
then the Shareholders shall, or shall cause the Shareholder Group to,
consistent with the provisions of this Agreement, promptly (in any event,
prior to the earliest to occur of (i) the record date for the next annual or
special meeting of shareholders of the Company, (ii) the record date for the
taking of any action of shareholders of the Company by written consent or
(iii) the purchase of any additional Voting Securities by any member of the
Shareholder Group) take all action necessary to reduce the amount of Voting
Securities Beneficially Owned by the Shareholder Group such that the
Significant Shareholders' Total Ownership Percentage is not greater than the
Combined Maximum Ownership Percentage; PROVIDED that if the Shareholder
becomes aware that the Significant Shareholders' Total Ownership Percentage
exceeds the Combined Maximum Ownership Percentage due to an acquisition by a
member of the PepsiCo Group of Voting Securities or the addition to the
PepsiCo Group of a new Affiliate that Beneficially Owns Voting Securities,
the Shareholder shall promptly inform the Company of such fact but shall not
be required to reduce the amount of Voting Securities Beneficially Owned by
the Shareholder Group due to such event so long as the Shareholder Group is
in compliance with the other provisions of this Agreement.

         (d)   During the term of this Agreement, if the Company purchases
shares of Common Stock from the public, whether by tender offer, open market
purchase or otherwise (a "REPURCHASE"), the Company shall contemporaneously
with the Repurchase offer to purchase from the Shareholder Group, on the same
terms and conditions, including price, as in the Repurchase, a percentage of
those shares of Common Stock Beneficially Owned by the Shareholder Group
equal to the percentage of shares of Common Stock to be Repurchased from the
Beneficial Owners of shares of Common Stock other than the Shareholder Group
(the "BUY-BACK OFFER"). The Company shall provide notice to the Shareholders
of its intention to engage in a Repurchase and of the mechanism by which the
Repurchase shall occur not less than thirty (30) days in advance of the date
on which the Repurchase is to be consummated, and the Shareholders shall
provide notice to the Company within ten (10) days of receipt of such notice
of whether the Shareholder Group intends to accept the Buy-Back Offer.

         Section 3.3. TOP-UP RIGHTS. During the term of this Agreement, if
the Shareholder Group's Total Ownership Percentage is below the Maximum
Ownership Percentage and the Significant Shareholders' Total Ownership
Percentage is below the Combined Maximum Ownership Percentage, the
Shareholder Group may at its option purchase Voting Securities from time to
time in the open market or otherwise in an amount not in excess of the amount
that would

                                     -9-

<PAGE>

cause either (x) the Shareholder Group's Total Ownership Percentage to exceed
the Maximum Ownership Percentage or (y) the Significant Shareholders' Total
Ownership Percentage to exceed the Combined Maximum Ownership Percentage.

         Section 3.4. CHARTER AND BY-LAWS. During the term of this Agreement
the Company shall not, and the Shareholder Group shall not, and shall not
facilitate any effort to, amend, alter or repeal, or propose the amendment,
alteration or repeal of, any provision of the Charter or the By-Laws in any
manner which is inconsistent with the terms of this Agreement. If at any time
during the term of this Agreement the provisions of this Agreement shall
conflict with the provisions of the Charter or the By-Laws, the parties shall
use all reasonable efforts, consistent with their fiduciary responsibilities,
to cause the provisions of the Charter and the By-Laws to be brought into
conformity with the provisions of this Agreement.

         Section 3.5. RIGHTS AGREEMENT. During the term of this Agreement,
the Company hereby agrees not to (i) amend any provision of the Rights
Agreement in any manner which is inconsistent with the terms of this
Agreement or the Merger Agreement and which adversely affects the rights of
the Shareholder Group under the terms of this Agreement or (ii) adopt any new
rights agreement which is inconsistent with the terms of this Agreement or
the Merger Agreement and which adversely affects the rights of the
Shareholder Group under the terms of this Agreement.

         Section 3.6. NO AGREEMENTS. During the term of this Agreement,
except as specifically contemplated in Section 3.7, no member of the
Shareholder Group shall, directly or indirectly, enter into any agreement or
other understanding with any member of the PepsiCo Group with respect to the
holding, voting, acquisition or disposition of Voting Securities.

         Section 3.7. DAKOTA HOLDINGS. Notwithstanding the provisions of
Section 3.6, members of the Shareholder Group (whether existing or newly
formed) and members of the PepsiCo Group may be parties to the Amended and
Restated Limited Liability Company Agreement of Dakota Holdings, attached as
Annex A to this Agreement (the "DAKOTA HOLDINGS AGREEMENT"), and to hold
interests in Dakota Holdings pursuant to the Dakota Holdings Agreement,
PROVIDED that (i) the Dakota Holdings Agreement expressly provides that (x)
the members of the Shareholder Group who are parties to the Dakota Holdings
Agreement have sole power with respect to the voting of that percentage of
the Voting Securities owned by Dakota Holdings equal to the Class A
Percentage Interest (as defined in the Dakota Holdings Agreement) (the "CLASS
A PERCENTAGE") of the Shareholder Group members and with respect to the
voting of such Voting Securities members of the PepsiCo Group shall have no
power, influence or discretion, and (y) the members of the PepsiCo Group who
are parties to the Dakota Holdings Agreement ultimately have sole power with
respect to the voting of their Class A Percentage of the Voting Securities
owned by Dakota Holdings and with respect to the voting of such Voting
Securities members of the Shareholder Group shall have no power, influence or
discretion which is not subject to the ultimate power of the PepsiCo Group to
direct the voting; and (ii) Dakota Holdings shall not take any action to
acquire, directly or indirectly, Beneficial Ownership of any additional
Voting Securities (excluding any Voting Securities acquired pursuant to
transactions contemplated by the Merger Agreement (including any Contingent
Payment Acquisitions) and excluding Voting Securities acquired through stock
dividends on then-owned Voting Securities and excluding the acquisition of
Voting Securities pursuant to the

                                    -10-

right of Pohlad Companies to acquire Common Stock with a value of $25 million
from the PepsiCo Group, in connection with the Merger). So long as the
proviso in the preceding sentence is complied with, for purposes of
calculating the Shareholder Group's Total Ownership Percentage, those Voting
Securities over which a member of the PepsiCo Group has the sole powers
described in clause (y) of clause (i) in the proviso in the preceding
sentence shall not be considered Beneficially Owned by the Shareholder Group
and a transfer of interests in Dakota Holdings from a member of the
Shareholder Group to a member of the PepsiCo Group shall be permitted with
the consent of the Affiliated Transaction Committee (or, if such Committee
shall not be in existence, by a committee of the Board composed entirely of
Independent Directors), which consent shall not be unreasonably withheld.

         Section 3.8. SPECIAL MEETINGS REQUESTED BY THE SHAREHOLDER;
NOMINATIONS. In the event that during the term of this Agreement the
Shareholder Group requests a special meeting of the stockholders of the
Company in accordance with the By-Laws, or the Shareholder Group nominates an
alternative slate of directors to the slate proposed by the Board at any
annual meeting of stockholders of the Company in accordance with the By-Laws,
the Company hereby agrees that the Company shall not, without the
Shareholders' consent, from the date of receipt of such request for a special
meeting or the date of receipt of such nomination, as the case may be, until
the adjournment of the requested special meeting or the annual meeting, as
the case may be, (i) take any action effecting a material change in its
capital structure, (ii) declare or pay a dividend (other than any regular
quarterly dividend), (iii) materially increase the compensation of any
executive officer or (iv) take any material action not in the ordinary course
of business; PROVIDED that this provision shall not restrict the ability of
the Company to comply with commitments entered into prior to the date of such
request.

         Section 3.9. OPTIONS. The Company shall not grant to any member of
the Shareholder Group any options to purchase Common Stock unless such grant
is approved by the Affiliated Transaction Committee (or, if such Committee
shall not be in existence, by a committee of the Board composed entirely of
Independent Directors).

                              ARTICLE IV

         Section 5.2. TERMINATION. This Agreement shall terminate upon
written agreement of the Company (which shall require the approval of the
Affiliated Transaction Committee (or, if such Committee shall not be in
existence, by a committee of the Board composed entirely of Independent
Directors)) and the Shareholders at any time to terminate this Agreement,
which termination shall occur at a time to be fixed in such mutual agreement.

                              ARTICLE VI

                             MISCELLANEOUS

         Section 6.1. INJUNCTIVE RELIEF. Each party hereto acknowledges that
it would be impossible to determine the amount of damages that would result
from any breach of any of the provisions of this Agreement and that the
remedy at law for any breach, or threatened breach, of any of such provisions
would likely be inadequate and, accordingly, agrees that each other party
shall, in addition to any other rights or remedies which it may have, be
entitled to seek such equitable and injunctive relief as may be available
from any court of competent jurisdiction to compel specific performance of,
or restrain any party from violating, any of such provisions. In connection
with any action or proceeding for injunctive relief, each party hereto hereby
waives the claim or defense that a remedy at law alone is adequate and
agrees, to the maximum extent permitted by law, to have each provision of
this Agreement specifically enforced against him or it, without the necessity
of posting bond or other security against him or it, and consents to the
entry of injunctive relief against him or it enjoining or restraining any
breach or threatened breach of such provisions of this Agreement.

        Section 6.2. SUCCESSORS AND ASSIGNS. This Agreement shall be binding
upon, shall inure to the benefit of and shall be enforceable by the Company
and by the Shareholders and their respective successors and permitted
assigns, and no such term or provision is for the benefit of, or intended to
create any obligations to, any other Person.

         Section 6.3. AMENDMENTS; WAIVER. (a) This Agreement may be amended
only by an agreement in writing executed by the parties hereto. Any approval
of an amendment of this Agreement upon the part of the Company shall require
the approval of the Affiliated Transaction Committee (or, if such Committee
shall not be in existence, by a committee of the Board composed entirely of
Independent Directors) at a duly convened meeting thereof.

         (b)  Either party may waive in whole or in part any benefit or right
provided to it under this Agreement, such waiver being effective only if
contained in a writing executed by the waiving party. No failure by any party
to insist upon the strict performance of any covenant, duty, agreement or
condition of this Agreement or to exercise any right or remedy consequent
upon breach thereof shall constitute a waiver of any such breach or of any
other covenant, duty, agreement or condition, nor shall any delay or omission
of either party to exercise any right hereunder in any manner impair the
exercise of any such right accruing to it thereafter. Any waiver of any
benefit or right provided to the Company under this Agreement shall require
the approval of a majority of the Board and approval of the Affiliated
Transaction Committee (or, if such Committee shall not be in existence, by a
committee of the Board composed entirely of Independent Directors) at a duly
convened meeting thereof.

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

        Where  X  =   the number of shares of Stock to be issued to the
                      Holder

               Y  =   the number of shares of Stock purchasable under the
                      Warrant or, if only a portion of the Warrant is being
                      exercised, the portion of the Warrant being canceled (at
                      the date of such calculation)

               A  =   the fair market value of one share of Stock (at the
                      date of such calculation)

               B  =   Exercise Price (as adjusted to the date of such
                      calculation)

                                       2
<PAGE>

For purposes of the above calculation, Fair Market Value (the "Fair Market
Value") of one share of Stock shall be the average closing price of one share of
Stock on any exchange or inter-dealer quotation system on which the Stock is
then traded for the five trading day period prior to the date o which the
Company receives the Holder's Notice of Exercise.  If the Stock is not then
traded on an exchange or inter-dealer quotation system, the Fair Market Value
shall be determined by the Company's Board of Directors in good faith.  If the
Holder does not agree with the Board's determination of Fair Market Value of the
Stock (the "Board Determination"), the Holder shall have the right within 10
days of his or its receipt of the Board Determination, to cause the Board of
Directors to select an investment banking firm (the "Arbiter") to determine the
Fair Market Value and the Board of Directors shall deliver written notice of
such selection to the Holder and the Company.  The Arbiter shall determine the
Fair Market Value of Stock and deliver its opinion to the Holder and the
Company.  The terms of engagement of the Arbiter shall require the Arbiter to
deliver such written opinion to the Holder and the Company within 45 days
following submission of such value determination to the Arbiter.  The Arbiter's
determination of Fair Market Value shall be binding.  The cost of the Arbiter
shall be borne by the Company if the Arbiter's determination of Fair Market
Value is greater than the Board Determination, and by the Holder if it is equal
to or less than the Board Determination.

     4.  NO FRACTIONAL SHARES OR SCRIP.  No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant.  In lieu of any fractional share to which the Holder would otherwise be
entitled, the Company shall make a cash payment equal to the Exercise Price
multiplied by such fraction.

     5.  REPLACEMENT OF WARRANT.  On receipt of evidence reasonably satisfactory
to the Company of the loss, theft, destruction or mutilation of this Warrant
and, in the case of loss, theft or destruction, on delivery of an indemnity
agreement reasonably satisfactory in form and substance to the Company or, in
the case of mutilation, on surrender and cancellation of this Warrant, the
Company at its expense shall execute and deliver, in lieu of this Warrant, a new
warrant of like tenor and amount.

     6.  RIGHTS OF SHAREHOLDERS.  The Holder shall not be entitled to vote or
receive dividends or be deemed the holder of Stock or any other securities of
the Company that may at any time be issuable on the exercise hereof for any
purpose, nor shall anything contained herein be construed to confer upon the
Holder, as such, any of the rights of a shareholder of the Company or any right
to vote for the election of directors or upon any matter submitted to
shareholders at any meeting thereof, or to give or withhold consent to any
corporate action (whether upon any recapitalization, issuance of stock,
reclassification of stock, change of par value, or change of stock to no par
value, consolidation, merger, conveyance, or otherwise) or to receive notice of
meetings, or to receive dividends or subscription rights or otherwise until this
Warrant shall have been exercised as provided herein.

     7.  TRANSFER OF WARRANT.

          7.1  Warrant Register.  The Company shall maintain a register (the
"Warrant Register") containing the names and addresses of the Holder or Holders.
Any Holder of this Warrant or any portion thereof may change his address as
shown on the Warrant Register by written notice to the Company requesting such
change. Any notice or written communication required or permitted to be given
to the Holder may be delivered or given by mail to such Holder as shown on the
Warrant Register and at the address shown on the Warrant Register.  Until this
Warrant is transferred on the Warrant Register of the Company, the Company may
treat the Holder as shown on the Warrant Register as the absolute owner of this
Warrant for all purposes, notwithstanding any notice to the contrary.

          7.2  Warrant Agent. The Company may, by written notice to the Holder,
appoint an agent for the purpose of maintaining the Warrant Register referred to
in Section 7.1 above, issuing the Stock or other securities then issuable upon
the exercise of this Warrant, exchanging this Warrant, replacing this Warrant or
any or all of the foregoing.  Thereafter, any such registration, issuance,
exchange, or replacement, as the case may be, shall be made at the office of
such agent.

          7.3  Transferability and Nonnegotiability of Warrant. This Warrant
(and the shares of Stock issuable upon the exercise thereof may not be
transferred or assigned in whole or in part without compliance with all
applicable federal and state securities laws by the transferor and the
transferee (including the delivery of investment representation letters and
legal opinions reasonably satisfactory to the Company, if such are requested
by the Company).

          7.4  Exchange Of Warrant Upon A Transfer. On surrender of this Warrant
for exchange, properly endorsed on the Assignment Form and subject to the
provisions of this Warrant with respect to compliance with the 1933 Act, the
Company at its expense shall issue to or on the order of the Holder a new
warrant or warrants of like tenor, in the name of the Holder or as the Holder
(on payment by the Holder of any applicable transfer taxes) may direct, for the
number of shares issuable upon exercise hereof.

          7.5  Compliance with Securities Laws and Restrictions on Transfer. The
Holder of this Warrant, by acceptance hereof, acknowledges that this Warrant and
the shares of Stock to be issued upon exercise hereof are being acquired solely
for the Holder's own account and not as a nominee for any other party, and for
investment and not with a view to a distribution or resale, and that the Holder
shall not offer, sell or otherwise dispose of this Warrant or any such shares of
Stock except under circumstances that will not result in a violation of the 1933
Act or any state securities laws.  Upon exercise of this Warrant the Holder
shall, if requested by the Company, confirm in writing, in a form satisfactory
to the Company, that the shares of Stock so purchased are being acquired solely
for the Holder's own account and not as a nominee for any other party, for
investment, and not with a view toward distribution or resale.

     8.  RESERVATION OF STOCK.  The Company covenants that during the term that
this Warrant is exercisable, the Company shall reserve from its authorized and
unissued Stock a sufficient number of shares to provide for the issuance of
Stock upon the exercise of this Warrant (collectively, the "Reserved Shares").
The Company further covenants that all Reserved Shares that may be issued upon
the exercise of rights represented by this Warrant and payment of the Exercise
Price, all as set forth herein, will be free from all taxes, liens and charges
in respect of the issue thereof (other than taxes in respect of any transfer
occurring contemporaneously or otherwise specified herein).  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 of Stock upon the
exercise of this Warrant.

     9.  RIGHT OF REDEMPTION.  At any time following the issuance of this
Warrant, if the closing price of the Stock on the Nasdaq SmallCap Market (or any
other exchange or inter-dealer quotation system on which the Stock is then
traded) exceeds $10.40 per share for a period of 20 consecutive trading days,
the Company may provide the Holder(s) with written notice of its intent to
redeem this Warrant on a date that is at least 30 days from the notice of intent
to redeem.  On such date, the Company shall redeem this Warrant for an aggregate
redemption price of $___________.  The Holder(s) from whom this Warrant is
redeemed, on the date of redemption, shall deliver this Warrant to the Company
during regular business hours, at the principal office of the Company.  On such
date, the Company shall issue and deliver to such Holder(s) a check in respect
of the aggregate redemption price for this Warrant.  Notwithstanding the
foregoing, however, the Holder(s), at its sole option, may choose to exercise
this Warrant at any time during the 30 day notice period required to be given by
the Company.

     10.  AMENDMENTS; WAIVERS.  Any term of this Warrant may be amended or
waived with the written consent of the Company and such number of Holders as
represent not less than fifty-one percent (51%) of the shares of Stock issuable
upon exercise of this Warrant.  Any amendments or waivers effected in accordance
with this Section 10 shall be binding upon each Holder, each future Holder, and
the Company; provided, however, that no special consideration or inducement may
be given to any Holder in connection with such consent that is not given ratably
to all Holders, and that such amendment or waiver must apply to all Holders
equally and ratably in accordance with the number of shares of Stock issuable
upon their respective exercises of portions of this Warrant.  No waivers of, or
exceptions to, any term, condition or provision of this Warrant, in any one or
more instances, shall be deemed to be, or construed as, a further or continuing
waiver of any such term, condition or provision. Except as provided in Section
12 hereof, no amendment or waiver shall (i) impose on the Warrantholder any
burden, constraint or restriction not otherwise existing at the time the Warrant
is issued, (ii) increase the exercise price of the Warrant, (iii) decrease the
exercise period, (iv) decrease the number of shares of Stock the Warrantholder
is eligible to receive upon exercise, or (v) materially change the terms of the
Warrant, without the consent of the Warrantholder.

     11.  GENERAL.

          11.1  Governing Law.  This Warrant shall be governed by and construed
according to the laws of the Commonwealth of Virginia, without reference to the
choice of law principles of any jurisdiction.

          11.2  Delays or Omissions. No delay or omission to exercise any right,
power, or remedy accruing to either party upon any breach or default under this
Warrant, shall be deemed a waiver of any other breach or default theretofore or
thereafter occurring.  Any waiver, permit, consent, or approval of any kind or
character on the part of either party of any breach or default under this
Warrant, or any waiver on the part of either party of any provisions or
conditions of this Warrant, must be in writing and shall be effective only to
the extent specifically set forth in such writing.  All remedies, either under
this Warrant or by law or otherwise afforded to either of the parties, shall be
cumulative and not alternative.

          11.3  References. Unless the context otherwise requires, any reference
to a "Section" refers to a section of this Warrant.

          11.4  Captions.  Captions of sections have been added only for
convenience and shall not be deemed to be a part of this Warrant.

     12.   ADJUSTMENTS.  The number of shares purchasable hereunder is subject
to adjustment from time to time as follows:

          12.1  Split-Ups, Split-Downs, Stock Dividends.  If the Company should
at any time or from time to time engage in a stock split, stock split-down or
stock dividend with respect to the Stock, the number of shares of Stock issuable
pursuant to this Warrant and the Exercise Price shall be rateably and equitably
adjusted, as determined by the Company's Board of Directors in its reasonable
discretion, provided that any adjustment shall be no less favorable than any
adjustment under the Company's Stock Incentive Plan.

          12.2  Reorganization, Merger or Sale of Assets.  If at any time while
this Warrant, or any portion thereof, is outstanding and unexpired there shall
be (i) a reorganization (other than a combination, reclassification, exchange or
subdivision of shares otherwise provided for herein), (ii) a merger or
consolidation of the Company with or into another corporation in which the
Company is not the surviving entity, or a reverse triangular merger in which the
Company is the surviving entity but the shares of the Company's capital stock
outstanding immediately prior to the merger are converted by virtue of the
merger into other property, whether in the form of securities, cash or
otherwise, or (iii) a sale or transfer of the Company's properties and assets
as, or substantially as, an entirety to any other person, then, as a part of
such reorganization, merger, consolidation, sale or transfer, lawful provision
shall be made so that the Holder(s) shall thereafter be entitled to receive upon
payment of the Exercise Price then in effect, the number of shares of stock or

                                        6
<PAGE>

other securities or property of the successor corporation resulting from such
reorganization, merger, consolidation, sale or transfer that a holder of the
shares deliverable upon exercise of this Warrant would have been entitled to
receive in such reorganization, consolidation, merger, sale of transfer if this
Warrant had been exercised immediately before such reorganization, merger,
consolidation, sale or transfer, all subject to further apply to successive
reorganizations, consolidations, mergers, sales and transfers and to the stock
or securities of any other corporation that are at the time receivable upon the
exercise of this Warrant.  If the per-share consideration payable to the Holder
hereof for shares in connection with any such transaction is in a form other
than cash or marketable securities, then the value of such consideration shall
be determined in good faith by the Company's Board of Directors.  In all events,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interests of the Holder after the transaction, to
the end that the provisions of this Warrant shall be applicable after that
event, as near as reasonably may be, in relation to any shares or other property
deliverable after that event upon exercise of this Warrant.

          12.3  Reclassification.  If the Company, at any time while this
Warrant, or any portion thereof, remains outstanding and unexpired, by
reclassification of securities or otherwise, shall change any of the securities
as to which purchase rights under this Warrant exist into the same or a
different number of securities of any other class or classes, this Warrant shall
thereafter represent the right to acquire such number and kind of securities as
would have been issuable as the result of such change with respect to the
securities that were subject to the purchase rights under this Warrant
immediately prior to such reclassification or other change and the Exercise
Price therefor shall be appropriately adjusted, all subject to further
adjustment as provided in this Section 12.

          12.4  No Impairment.  The Company will not, by any voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed hereunder by the Company, but will at all times in good
faith assist in the carrying out of all the provisions of this Section 12 and
in the taking of all such action as may be necessary or appropriate in order to
protect the rights of the Holders of this Warrant against impairment.
