                                    ARTICLE I

                              EXERCISE OF WARRANTS

         1.1 Method of Exercise. The Warrants represented hereby may be
exercised by the holder hereof, in whole or in part, at any time and from time
to time on or after the date hereof until 5:00 p.m., Houston, Texas time, on
January 31, 2006. To exercise the Warrants, the holder hereof shall deliver to
the Company, at the Warrant Office designated in Section hereof, (i) a written
notice in the form of the Subscription Notice attached as an exhibit hereto,
stating therein the election of such holder to exercise the Warrants in the
manner provided in the Subscription Notice; (ii) payment in full of the Exercise
Price (A) in cash or by bank check for all Warrant Shares purchased hereunder,
or (B) through a "cashless" or "net-issue" exercise of each such Warrant
("Cashless Exercise"); the holder shall exchange each Warrant subject to a
Cashless Exercise for that number of Warrant Shares determined by multiplying
the number of Warrant Shares issuable hereunder by a fraction, the numerator of
which shall be the difference between (x) the Market Price and (y) the Exercise
Price for each such Warrant, and the denominator of which shall be the Market
Price; the Subscription Notice shall set forth the calculation upon which the
Cashless Exercise is based, or (C) a combination of (A) and (B) above; and (iii)
this Warrant. The Warrants shall be deemed to be exercised on the date of
receipt by the Company of the Subscription Notice, accompanied by payment for
the Warrant Shares and surrender of this Warrant, as aforesaid, and such date is
referred to herein as the "Exercise Date". Upon such exercise, the Company
shall, as promptly as practicable and in any event within ten (10) business
days, issue and deliver to such holder a certificate or certificates for the
full number of the Warrant Shares purchased by such holder hereunder, and shall,
unless the Warrants have expired, deliver to the holder hereof a new Warrant
representing the number of Warrants, if any, that shall not have been exercised,
in all other respects identical to this Warrant. As permitted by applicable law,
the Person in whose name the certificates for Common Stock are to be issued
shall be deemed to have become a holder of record of such Common Stock on the
Exercise Date and shall be entitled to all of the benefits of such holder on the
Exercise Date, including without limitation, the right to receive dividends and
other distributions for which the record date falls on or after the Exercise
Date and the right to exercise voting rights.

         1.2 Expenses and Taxes. The Company shall pay all expenses and taxes
(including, without limitation, all documentary, stamp, transfer or other
transactional taxes) other than income taxes attributable to the preparation,
issuance or delivery of the Warrants and of the shares of Common Stock issuable
upon exercise of the Warrants.

         1.3 Reservation of Shares. The Company shall reserve at all times so
long as the Warrants remain outstanding, or shall have available in reserve by
February 28, 2001, free from preemptive rights, out of its treasury Common Stock
or its authorized but unissued shares of Common Stock, or both, solely for the
purpose of effecting the exercise of the Warrants, a sufficient number of shares
of Common Stock to provide for the exercise of the Warrants.

<PAGE>

         1.4 Valid Issuance. All shares of Common Stock that may be issued upon
exercise of the Warrants will, upon issuance by the Company, be duly and validly
issued, fully paid and nonassessable and free from all taxes, liens and charges
with respect to the issuance thereof and, without limiting the generality of the
foregoing, the Company shall take no action or fail to take any action which
will cause a contrary result (including, without limitation, any action that
would cause the Exercise Price to be less than the par value, if any, of the
Common Stock).

         1.5 Purchase Agreement. The Warrants represented hereby are part of a
duly authorized issuance and sale of warrants to purchase Common Stock issued
and sold pursuant to that certain Agreement of Purchase and Sale dated as of
January 23, 2001 (the "Agreement"), among the Company and the Holder. The holder
hereof shall be entitled to registration under the Securities Act and any
applicable state securities or blue sky laws to the extent set forth in the
Registration Rights Agreement, as hereafter amended. The terms of the Agreement
are hereby incorporated herein for all purposes and shall be considered a part
of this Warrant as if they had been fully set forth herein. Notwithstanding the
previous sentence, in the event of any conflict between the provisions of the
Agreement and of this Warrant, the provisions of this Warrant shall control.

         1.6 Acknowledgment of Rights. At the time of the exercise of the
Warrants in accordance with the terms hereof and upon the written request of the
holder hereof, the Company will acknowledge in writing its continuing obligation
to afford to such holder any rights (including, without limitation, any right to
registration of the Warrant Shares) to which such holder shall continue to be
entitled after such exercise in accordance with the provisions of this Warrant;
provided, however, that if the holder hereof shall fail to make any such
request, such failure shall not affect the continuing obligation of the Company
to afford to such holder any such rights.

         1.7 No Fractional Shares. The Company shall not be required to issue
fractional shares of Common Stock on the exercise of this Warrant. If more than
one Warrant shall be presented for exercise at the same time by the same holder,
the number of full shares of Common Stock which shall be issuable upon such
exercise shall be computed on the basis of the aggregate number of whole shares
of Common Stock purchasable on exercise of the Warrants so presented. If any
fraction of a share of Common Stock would, except for the provisions of this
Section, be issuable on the exercise of this Warrant, the Company shall pay an
amount in cash calculated by it to be equal to the Market Price of one share of
Common Stock at the time of such exercise multiplied by such fraction computed
to the nearest whole cent.

<PAGE>

                                   ARTICLE II

                                    TRANSFER

         2.1 Warrant Office. The Company shall maintain an office for certain
purposes specified herein (the "Warrant Office"), which office shall initially
be the Company's offices at 3748 Highway #45 North, Columbus, Mississippi 39701
and may subsequently be such other office of the Company or of any transfer
agent of the Common Stock in the continental United States as to which written
notice has previously been given to the holder hereof. The Company shall
maintain, at the Warrant Office, a register for the Warrants in which the
Company shall record the name and address of the Person in whose name this
Warrant has been issued, as well as the name and address of each permitted
assignee of the rights of the registered owner hereof.

         2.2 Ownership of Warrants. The Company may deem and treat the Person in
whose name the Warrants are registered as the holder and owner hereof
(notwithstanding any notations of ownership or writing hereon made by anyone
other than the Company) for all purposes and shall not be affected by any notice
to the contrary until presentation of this Warrant for registration of transfer
as provided in this Article II. Notwithstanding the foregoing, the Warrants
represented hereby, if properly assigned in compliance with this Article II, may
be exercised by an assignee for the purchase of Warrant Shares without having a
new Warrant issued.

         2.3 Restrictions on Transfer of Warrants. The Company agrees to
maintain at the Warrant Office books for the registration and transfer of the
Warrants. Subject to the restrictions on transfer of the Warrants in this
Section, the Company, from time to time, shall register the transfer of the
Warrants in such books upon surrender of this Warrant at the Warrant Office
properly endorsed or accompanied by appropriate instruments of transfer and
written instructions for transfer satisfactory to the Company. Upon any such
transfer and upon payment by the holder or its transferee of any applicable
transfer taxes, new Warrants shall be issued to the transferee and the
transferor (as their respective interests may appear) and the surrendered
Warrants shall be canceled by the Company. The Company shall pay all taxes
(other than securities transfer taxes or income taxes) and all other expenses
and charges payable in connection with the transfer of the Warrants pursuant to
this Section.

            2.3.1 Restrictions in General. The holder of the Warrants agrees
         that it will not transfer the Warrants unless registration of
         such Warrant Shares under the Securities Act and any applicable state
         securities or blue sky laws has become effective or the holder has
         provided to the Company an opinion of counsel acceptable to the Company
         that such registration is not required. Prior to any transfer (other
         than the grant of a security interest) as provided herein, the
         transferor shall provide written notice to the Company and an opinion
         of counsel to the effect that the proposed transfer is exempt from
         registration under all applicable securities laws, all in form and
         substance reasonably satisfactory to the Company. Any lender or lenders
         to which the Holder grants a security interest in the Warrants shall be
         entitled to exercise all remedies to which it is entitled by contract
         or by law, including (without limitation) transferring the Warrants
         into its own name or into the name of any purchaser at any sale
         undertaken in connection with enforcement by such lender of its
         remedies.

<PAGE>

         2.4 Compliance with Securities Laws. Subject to the terms of the
Registration Rights Agreement among the Holder and the Company dated as of
January 23, 2001, as may be amended from time to time (the "Registration Rights
Agreement"), and notwithstanding any other provisions contained in this Warrant
except Section 2.3.1, the holder hereof understands and agrees that the
following restrictions and limitations shall be applicable to all Warrant Shares
and to all resales or other transfers thereof pursuant to the Securities Act:

             2.4.1 The holder hereof agrees that the Warrant Shares shall not be
         sold or otherwise transferred unless the Warrant Shares are registered
         under the Securities Act and applicable state securities or blue sky
         laws or are exempt therefrom.

             2.4.2 A legend in substantially the following form will be placed

             2.4.3 Stop transfer instructions will be imposed with respect to

                                   ARTICLE III

                                  ANTI-DILUTION

         3.1 Anti-Dilution Provisions. The Exercise Price shall be subject to
adjustment from time to time as hereinafter provided. Upon each adjustment of
the Exercise Price, the holder of this Warrant shall thereafter be entitled to
purchase, at the Exercise Price resulting from such adjustment, the number of
shares of Common Stock obtained by multiplying the Exercise Price in effect
immediately prior to such adjustment by the number of shares purchasable
pursuant hereto immediately prior to such adjustment and dividing the product
thereof by the Exercise Price resulting from such adjustment.

         3.2 Adjustment of Exercise Price Upon Issuance of Common Stock.

             3.2.1 (A) If and whenever after the date hereof the Company
         shall issue or sell any Common Stock for no consideration or for a
         consideration per share less than the Exercise Price, then, forthwith
         upon such issue or sale, the Exercise Price shall be reduced (but not
         increased, except as otherwise specifically provided in Section
         hereof), to the lower price per share (calculated to the nearest
         one-ten thousandth of a cent) but in any event not less than $.001 per
         share.

                   (B) Notwithstanding the provisions of this Section, no
         adjustment shall be made in the Exercise Price in the event that the
         Company issues, in one or more transactions, (i) Common Stock or
         convertible securities upon exercise of any options issued to officers,
         directors or employees of the Company pursuant to a stock option plan
         or an employment, severance or consulting agreement as now or hereafter
         in effect, in each case approved by the Board of Directors (provided
         that the aggregate number of shares of Common Stock which may be
         issuable, including options issued prior to the date hereof, under all
         such employee plans and agreements shall at no time exceed the number
         of such shares of Common Stock that are issuable under currently
         effective employee plans and agreements); (ii) Common Stock upon
         exercise of any stock purchase warrant or option (other than the
         options referred to in clause (i) above) or other convertible security
         outstanding on the date hereof; or (iii) Common Stock issued as
         consideration in acquisitions (including warrants, options or
         convertible securities issued as consideration for an acquisition or to
         officers, directors or employees of the acquired entity in conjunction
         therewith). In addition, for purposes of calculating any adjustment of
         the Exercise Price as provided in this Section, all of the shares of
         Common Stock issuable pursuant to any of the foregoing shall be assumed
         to be outstanding prior to the event causing such adjustment to be
         made.

             3.2.2 For purposes of this Section, the following Sections to
         inclusive, shall be applicable:

                   (A) Issuance of Rights or Options. In case at any time after
         the date hereof the Company shall in any manner grant (whether directly
         or by assumption in a merger or otherwise) any rights to subscribe for
         or to purchase, or any options for the purchase of, Common Stock or any
         stock or securities convertible into or exchangeable for Common Stock
         (such convertible or exchangeable stock or securities being herein
         called "Convertible Securities") (other than warrants, options or
         convertible securities issued as consideration for or assumed in
         conjunction with an acquisition or to officers, directors or employees
         of the acquired entity in conjunction therewith), whether or not such
         rights or options or the right to convert or exchange any such
         Convertible Securities are immediately exercisable, and the price per
         share for which shares of Common Stock are issuable upon the exercise
         of such rights or options or upon conversion or exchange of such
         Convertible Securities (determined by dividing (i) the total amount, if
         any, received or receivable by the Company as consideration for the
         granting of such rights or

<PAGE>

         options, plus the minimum aggregate amount of additional consideration,
         if any, payable to the Company upon the exercise of such rights or
         options, or plus, in the case of such rights or options that relate to
         Convertible Securities, the minimum aggregate amount of additional
         consideration, if any, payable upon the issue or sale of such
         Convertible Securities and upon the conversion or exchange thereof, by
         (ii) the total maximum number of shares of Common Stock issuable upon
         the exercise of such rights or options or upon the conversion or
         exchange of all such Convertible Securities issuable upon the exercise
         of such rights or options) shall be less than the Exercise Price in
         effect as of the date of granting such rights or options, then the
         total maximum number of shares of Common Stock issuable upon the
         exercise of such rights or options or upon conversion or exchange of
         all such Convertible Securities issuable upon the exercise of such
         rights or options shall be deemed to be outstanding as of the date of
         the granting of such rights or options and to have been issued for such
         price per share, with the effect on the Exercise Price specified in
         Section hereof. Except as provided in Section hereof, no further
         adjustment of the Exercise Price shall be made upon the actual issuance
         of such Common Stock or of such Convertible Securities upon exercise of
         such rights or options or upon the actual issuance of such Common Stock
         upon conversion or exchange of such Convertible Securities.

                 (B) Change in Option Price or Conversion Rate. Upon the
         happening of any of the following events, namely, if the purchase price
         provided for in any right or option referred to in Section, the
         additional consideration, if any, payable upon the conversion or
         exchange of any Convertible Securities referred to in Section, or the
         rate at which any Convertible Securities referred to in Section, are
         convertible into or exchangeable for Common Stock shall change (other
         than under or by reason of provisions designed to protect against
         dilution), the Exercise Price then in effect hereunder shall forthwith
         be readjusted (increased or decreased, as the case may be) to the
         Exercise Price that would have been in effect at such time had such
         rights, options or Convertible Securities still outstanding provided
         for such changed purchase price, additional consideration or conversion
         rate, as the case may be, at the time initially granted, issued or
         sold. On the expiration of any such option or right referred to in
         Section, or on the termination of any such right to convert or exchange
         any such Convertible Securities referred to in Section, the Exercise
         Price then in effect hereunder shall forthwith be readjusted (increased
         or decreased, as the case may be) to the Exercise Price that would have
         been in effect at the time of such expiration or termination had such
         right, option or Convertible Securities, to the extent outstanding
         immediately prior to such expiration or termination, never been
         granted, issued or sold, and the Common Stock issuable thereunder shall
         no longer be deemed to be outstanding. If the purchase price provided
         for in Section or the rate at which any Convertible Securities referred
         to in Section are convertible is reduced at any time under or by reason
         of provisions with respect thereto designed to protect against
         dilution, then in case of the delivery of Common Stock upon the
         exercise of any such right or option or upon conversion or exchange of
         any such Convertible Securities, the Exercise Price then in effect
         hereunder shall, if not already adjusted, forthwith be adjusted to such
         amount as would have obtained had such right, option or Convertible
         Securities never been issued as to such Common Stock and had
         adjustments been made upon the issuance of the Common Stock delivered
         as aforesaid, but only if as a result of such adjustment the Exercise
         Price then in effect hereunder is thereby reduced.

<PAGE>

                 (C) Consideration for Stock. In case at any time Common Stock
         or Convertible Securities or any rights or options to purchase any such
         Common Stock or Convertible Securities shall be issued or sold for
         cash, the consideration therefor shall be deemed to be the amount
         received by the Company therefor. In case at any time any Common Stock,
         Convertible Securities or any rights or options to purchase any such
         Common Stock or Convertible Securities shall be issued or sold for
         consideration other than cash, the amount of the consideration other
         than cash received by the Company shall be deemed to be the fair value
         of such consideration, as determined reasonably and in good faith by
         the Board of Directors of the Company. In case at any time any Common
         Stock, Convertible Securities or any rights or options to purchase any
         Common Stock or Convertible Securities shall be issued in connection
         with any merger or consolidation in which the Company is the surviving
         corporation, the amount of consideration received therefor shall be
         deemed to be the fair value, as determined reasonably and in good faith
         by the Board of Directors of the Company, of such portion of the assets
         and business of the nonsurviving corporation as such Board of Directors
         may determine to be attributable to such Common Stock, Convertible
         Securities, rights or options as the case may be. In case at any time
         any rights or options to purchase any shares of Common Stock or
         Convertible Securities shall be issued in connection with the issuance
         and sale of other securities of the Company, together consisting of one
         integral transaction in which no consideration is allocated to such
         rights or options by the parties, such rights or options shall be
         deemed to have been issued with consideration.

                 (D) Record Date. In the case the Company shall take a record of
         the holders of its Common Stock for the purpose of entitling them (i)
         to receive a dividend or other distribution payable in Common Stock or
         Convertible Securities, or (ii) to subscribe for or purchase Common
         Stock or Convertible Securities, then such record date shall be deemed
         to be the date of the issuance or sale of the Common Stock or
         Convertible Securities deemed to have been issued or sold as a result
         of the declaration of such dividend or the making of such other
         distribution or the date of the granting of such right of subscription
         or purchase, as the case may be.

                 (E) Treasury Shares. The number of shares of Common Stock
         outstanding at any given time shall not include shares owned directly
         by the Company in treasury, and the disposition of any such shares
         shall be considered an issuance or sale of Common Stock for the purpose
         of this Section.

         3.3 Stock Dividends. In case the Company shall declare a dividend or
make any other distribution upon any shares of the Company, payable in Common
Stock or Convertible Securities, any Common Stock or Convertible Securities, as
the case may be, issuable in payment of such dividend or distribution shall be
deemed to have been issued or sold without consideration.

<PAGE>

         3.4 Stock Splits and Reverse Splits. In the event that the Company
shall at any time subdivide its outstanding shares of Common Stock into a
greater number of shares, the Exercise Price in effect immediately prior to such
subdivision shall be proportionately reduced and the number of Warrant Shares
purchasable pursuant to this Warrant immediately prior to such subdivision shall
be proportionately increased, and conversely, in the event that the outstanding
shares of Common Stock shall at any time be combined into a smaller number of
shares, the Exercise Price in effect immediately prior to such combination shall
be proportionately increased and the number of Warrant Shares purchasable upon
the exercise of this Warrant immediately prior to such combination shall be
proportionately reduced. Except as provided in this Section, no adjustment in
the Exercise Price and no change in the number of Warrant Shares purchasable
shall be made under this Article III as a result of, or by reason of, any such
subdivision or combination.

         3.5 Reorganizations and Asset Sales. If any capital reorganization or
reclassification of the capital stock of the Company, or any consolidation,
merger or share exchange of the Company with another Person, or the sale,
transfer or other disposition of all or substantially all of its assets to
another Person shall be effected in such a way that a holder of Common Stock of
the Company shall be entitled to receive capital stock, securities or assets
with respect to or in exchange for their shares, then the following provisions
shall apply:

             3.5.1 As a condition of such reorganization, reclassification,
         consolidation, merger, share exchange, sale, transfer or other
         disposition (except as otherwise provided below in this Section),
         lawful and adequate provisions shall be made whereby the holder of
         Warrants shall thereafter have the right to purchase and receive upon
         the terms and conditions specified in this Warrant and in lieu of the
         Warrant Shares immediately theretofore receivable upon the exercise of
         the rights represented hereby, such shares of capital stock, securities
         or assets as may be issued or payable with respect to or in exchange
         for a number of outstanding shares of such Common Stock equal to the
         number of Warrant Shares immediately theretofore so receivable had such
         reorganization, reclassification, consolidation, merger, share exchange
         or sale not taken place, and in any such case appropriate provision
         reasonably satisfactory to such holder shall be made with respect to
         the rights and interests of such holder to the end that the provisions
         hereof (including, without limitation, provisions for adjustments of
         the Exercise Price and of the number of Warrant Shares receivable upon
         the exercise) shall thereafter be applicable, as nearly as possible, in
         relation to any shares of capital stock, securities or assets
         thereafter deliverable upon the exercise of Warrants.

             3.5.2 In the event of a merger, share exchange or consolidation of
         the Company with or into another Person as a result of which a number
         of shares of Common Stock or its equivalent of the successor Person
         greater or lesser than the number of shares of Common Stock outstanding
         immediately prior to such merger, share exchange or consolidation are
         issuable to holders of Common Stock, then the Exercise Price in effect
         immediately prior to such merger, share exchange or consolidation shall
         be adjusted in the same manner as though there were a subdivision or
         combination of the outstanding shares of Common Stock.

<PAGE>

             3.5.3 The Company shall not effect any such consolidation, merger,
         share exchange, sale, transfer or other disposition unless prior to or
         simultaneously with the consummation thereof the successor Person (if
         other than the Company) resulting from such consolidation, share
         exchange or merger of the Person purchasing or otherwise acquiring such
         assets shall have assumed by written instrument executed and mailed or
         delivered to the holder hereof at the last address of such holder
         appearing on the books of the Company the obligation to deliver to such
         holder such shares of capital stock, securities or assets as, in
         accordance with the foregoing provisions, such holder may be entitled
         to receive, and all other liabilities and obligations of the Company
         hereunder. Upon written request by the holder hereof, such successor
         Person will issue a new warrant revised to reflect the modifications in
         this Warrant effected pursuant to this Section.

             3.5.4 If a purchase, tender or exchange offer is made to and
         accepted by the holders of 50% or more of the outstanding shares of
         Common Stock, the Company shall not effect any consolidation, merger,
         share exchange or sale, transfer or other disposition of all or
         substantially all of the Company's assets with the Person having made
         such offer or with any affiliate of such Person, unless prior to the
         consummation of such consolidation, merger, share exchange, sale,
         transfer or other disposition the holder hereof shall have been given a
         reasonable opportunity to then elect to receive upon the exercise of
         the Warrants either the capital stock, securities or assets then
         issuable with respect to the Common Stock or the capital stock,
         securities or assets, or the equivalent, issued to previous holders of
         the Common Stock in accordance with such offer.

         3.6 Adjustment for Asset Distribution. If the Company declares a
dividend or other distribution payable to all holders of shares of Common Stock
in evidences of indebtedness of the Company or other assets of the Company
(including, cash (other than regular cash dividends declared by the Board of
Directors), capital stock (other than Common Stock, Convertible Securities or
options or rights thereto) or other property), the Exercise Price in effect
immediately prior to such declaration of such dividend or other distribution
shall be reduced by an amount equal to the amount of such dividend or
distribution payable per share of Common Stock, in the case of a cash dividend
or distribution, or by the fair value of such dividend or distribution per share
of Common Stock (as reasonably determined in good faith by the Board of
Directors of the Company), in the case of any other dividend or distribution.
Such reduction shall be made whenever any such dividend or distribution is made
and shall be effective as of the date as of which a record is taken for the
purpose of such dividend or distribution or, if a record is not taken, the date
as of which holders of record of Common Stock entitled to such dividend or
distribution are determined.

         3.7 De Minimis Adjustments. No adjustment in the number of shares of
Common Stock purchasable hereunder shall be required unless such adjustment
would require an increase or decrease of at least one share of Common Stock
purchasable upon an exercise of each Warrant

<PAGE>

and no adjustment in the Exercise Price shall be required unless such adjustment
would require an increase or decrease of at least $0.01 in the Exercise Price;
provided, however, that any adjustments which by reason of this Section are not
required to be made shall be carried forward and taken into account in any
subsequent adjustment. All calculations shall be made to the nearest full share
or nearest one hundredth of a dollar, as applicable.

         3.8 Notice of Adjustment. Whenever the Exercise Price or the number of
Warrant Shares issuable upon the exercise of the Warrants shall be adjusted as
herein provided, or the rights of the holder hereof shall change by reason of
other events specified herein, the Company shall compute the adjusted Exercise
Price and the adjusted number of Warrant Shares in accordance with the
provisions hereof and shall prepare an Officer's Certificate setting forth the
adjusted Exercise Price and the adjusted number of Warrant Shares issuable upon
the exercise of the Warrants or specifying the other shares of stock, securities
or assets receivable as a result of such change in rights, and showing in
reasonable detail the facts and calculations upon which such adjustments or
other changes are based. The Company shall cause to be mailed to the holder
hereof copies of such Officer's Certificate together with a notice stating that
the Exercise Price and the number of Warrant Shares purchasable upon exercise of
the Warrants have been adjusted and setting forth the adjusted Exercise Price
and the adjusted number of Warrant Shares purchasable upon the exercise of the
Warrants.

         3.9 Notifications to Holders. In case at any time the Company proposes:

             (i) to declare any dividend upon its Common Stock payable in
         capital stock or make any special dividend or other distribution (other
         than cash dividends) to the holders of its Common Stock;

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

             (iii) to effect any capital reorganization, or reclassification of
         the capital stock of the Company, or consolidation, merger or share
         exchange of the Company with another Person, or sale, transfer or other
         disposition of all or substantially all of its assets; or

             (iv) to effect a voluntary or involuntary dissolution, liquidation
         or winding up of the Company,

then, in any one or more of such cases, the Company shall give the holder hereof
(a) at least 10 days' (but not more than 90 days') prior written notice of the
date on which the books of the Company shall close or a record shall be taken
for such dividend, distribution or subscription rights or for determining rights
to vote in respect of such issuance, reorganization, reclassification,
consolidation, merger, share exchange, sale, transfer, disposition, dissolution,
liquidation or winding up, and (b) in the case of any such issuance,
reorganization, reclassification, consolidation, merger, share exchange, sale,
transfer, disposition, dissolution, liquidation or winding up, at least 10 days'
(but not more than 90 days') prior written notice of

<PAGE>

the date when the same shall take place. Such notice in accordance with the
foregoing clause (a) shall also specify, in the case of any such dividend,
distribution or subscription rights, the date on which the holders of Common
Stock shall be entitled thereto, and such notice in accordance with the
foregoing clause (b) shall also specify the date on which the holders of Common
Stock shall be entitled to exchange their Common Stock, as the case may be, for
securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, share exchange, sale, transfer,
disposition, dissolution, liquidation or winding up, as the case may be.

         3.10 Company to Prevent Dilution. If any event or condition occurs as
to which other provisions of this Article III are not strictly applicable or if
strictly applicable would not fairly protect the exercise or purchase rights of
the Warrants evidenced hereby in accordance with the essential intent and
principles of such provisions, or that might materially and adversely affect the
exercise or purchase rights of the holder hereof under any provisions of this
Warrant, then the Company shall make such adjustments in the application of such
provisions, in accordance with such essential intent and principles, so as to
protect such exercise and purchase rights as aforesaid, and any adjustments
necessary with respect to the Exercise Price and the number of Warrant Shares
purchasable hereunder so as to preserve the rights of the holder hereunder. In
no event shall any such adjustment have the effect of increasing the Exercise
Price as otherwise determined pursuant to this Article III except in the event
of a combination of shares of the type contemplated in Section hereof, and then
in no event to an amount greater than the Exercise Price as adjusted pursuant to
Section hereof.

                                   ARTICLE IV

                                  MISCELLANEOUS
