                                    ARTICLE I

                              EXERCISE OF WARRANTS

     I.1 Method of Exercise.

        (A) Subject to Section 1.1 (B), 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
October 10, 2002. To exercise the  Warrants,  the holder hereof shall deliver to
the  Company,  at the Warrant  Office  designated  in Section 2.1 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.

        (B) In the event that the Market  Price for the  Company's  Common Stock
exceeds  $_____  per share for  twenty  (20)  consecutive  trading  days and the
trading volume in the Company's Common Stock during each of such twenty days was
at least __________  shares per day, the Company shall have the right to require
exercise of the  Warrant.  If the Holder has not  exercised  the  Warrants on or
before the thirtieth  calendar day after the twentieth  consecutive  trading day
referenced in the preceding  sentence,  the Company shall be entitled to redeem,
effective on the thirty-first day after the twentieth  consecutive  trading day,
all of the  Warrants  which have not been  exercised  at such date at a price of
$_____ per Warrant.

     I.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.

     I.3  Reservation of Shares.  The Company shall reserve at all times so long
as the Warrants  remain  outstanding,  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.


                                       3


     I.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).

     I.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 the
date hereof (the  "Agreement"),  between 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.

     I.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.

     I.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 1.7, 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.


                                   ARTICLE II

                                    TRANSFER

     II.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.

     II.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.

     II.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 2.3, 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 cancelled 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.


                                       4


        II.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.
Notwithstanding  the preceding  sentence,  however,  St. James Capital Partners,
L.P.,  as the  initial  Holder of the  Warrants,  may  transfer  Warrants to its
partners of record on September 30, 1997 at any time and may at any time grant a
security  interest  in the  Warrants  to its  lender  or  lenders.  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.  The
partners of St. James Capital  Partners,  L.P. shall not be entitled to transfer
Warrants  prior to completion of a registered  public  offering of the Company's
Common Stock.

     II.4  Compliance  with  Securities  Laws.  Subject  to  the  terms  of  the
Registration  Rights  Agreement  between the Holder and the Company  dated as of
June 5, 1997, as amended or modified (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:

        II.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.

        II.4.2 A legend in  substantially  the following  form will be placed on
the certificate(s) evidencing the Warrant Shares:

                           "THE SECURITIES  REPRESENTED BY THIS CERTIFICATE HAVE
                  NOT BEEN  REGISTERED  UNDER  THE  SECURITIES  ACT OF 1933,  AS
                  AMENDED  (THE  "SECURITIES  ACT"),  OR  ANY  OTHER  APPLICABLE
                  SECURITIES LAW AND, ACCORDINGLY, THE SECURITIES REPRESENTED BY
                  THIS  CERTIFICATE  MAY NOT BE RESOLD,  PLEDGED,  OR  OTHERWISE
                  TRANSFERRED,  EXCEPT  PURSUANT  TO AN  EFFECTIVE  REGISTRATION
                  STATEMENT UNDER, OR IN A TRANSACTION  EXEMPT FROM REGISTRATION
                  UNDER,  THE  SECURITIES  ACT AND IN ACCORDANCE  WITH ANY OTHER
                  APPLICABLE SECURITIES LAWS."

        II.4.3 Stop  transfer  instructions  will be imposed with respect to the
Warrant Shares so as to restrict  resale or other transfer  thereof,  subject to
this Section 2.4.

                                   ARTICLE III

                                  ANTI-DILUTION

     III.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.

     III.2 Adjustment of Exercise Price Upon Issuance of Common Stock.

        III.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 3.2.2(C) hereof),  to the price (calculated to
the nearest one-ten  thousandth of a cent)  determined by dividing (x) an amount
equal  to the  sum of (i)  the  aggregate  number  of  shares  of  Common  Stock
outstanding  immediately prior to such issue or sale multiplied by then existing
Exercise  Price plus (ii) the  consideration  received by the Company  upon such
issue or sale by (y) the aggregate number of shares of Common Stock  outstanding
immediately after such issue or sale.


                                       5


              (B)  Notwithstanding  the  provisions  of  this  Section  3.2,  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 the Warrants or any
other warrant issued pursuant to the terms of the Agreement or otherwise  issued
to the Holder; (iii) 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;  (iv) Common Stock upon
conversion  of  the  Note;  or (v)  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
3.2, 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.

        III.2.2  For  purposes  of this  Section  3.2,  the  following  Sections
3.2.2(A) to 3.2.2(E) 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 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 3.2.1 hereof. Except as provided
     in Section 3.2.2 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  3.2.2,   the  additional
     consideration,  if any,  payable  upon the  conversion  or  exchange of any
     Convertible  Securities  referred to in Section 3.2.2, or the rate at which
     any Convertible  Securities  referred to in Section 3.2.2,  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  3.2.2,  or on the  termination of any such right to
     convert or exchange any such Convertible  Securities referred to in Section
     3.2.2,  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 3.2.2 or the rate at which any Convertible  Securities  referred to
     in Section 3.2.2 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.


                                       6


          (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 3.2.

     III.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.

     III.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 3.4, 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.


                                       7


     III.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:

        III.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 3.5),  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.

        III.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.

        III.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.

        III.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.

     III.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.

     III.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 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  3.7 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.


                                       8


     III.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.

     III.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 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.

     III.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 3.4 hereof,  and
then in no event  to an  amount  greater  than the  Exercise  Price as  adjusted
pursuant to Section 3.4 hereof.


                                       9


                                   ARTICLE IV

                                  MISCELLANEOUS

     IV.1 Entire Agreement. This Warrant, together with the Agreement,  contains
the entire  agreement  between the holder hereof and the Company with respect to
the Warrant Shares purchasable upon exercise hereof and the related transactions
and supersedes all prior arrangements or understandings with respect thereto.

     IV.2  Governing  Law.  This warrant  shall be governed by and  construed in
accordance with the laws of the State of Delaware.

     IV.3 Waiver and  Amendment.  Any term or  provision  of this Warrant may be
waived at any time by the party which is entitled  to the  benefits  thereof and
any term or provision of this Warrant may be amended or supplemented at any time
by agreement of the holder hereof and the Company, except that any waiver of any
term or condition, or any amendment or supplementation, of this Warrant shall be
in  writing.  A waiver of any breach or  failure to enforce  any of the terms or
conditions of this Warrant shall not in any way effect, limit or waive a party's
rights hereunder at any time to enforce strict compliance  thereafter with every
term or condition of this Warrant.

     IV.4  Illegality.  In the  event  that  any one or  more of the  provisions
contained  in this  Warrant  shall  be  determined  to be  invalid,  illegal  or
unenforceable  in any  respect  for  any  reason,  the  validity,  legality  and
enforceability  of any such  provision  in any other  respect and the  remaining
provisions  of this Warrant shall not, at the election of the party for whom the
benefit of the provision exists, be in any way impaired.

     IV.5  Copy of  Warrant.  A copy of this  Warrant  shall be filed  among the

this Warrant or at any more recent address of which the holder hereof shall have
notified  the  Company in  writing.  Any notice or other  document  required  or
permitted to be given or  delivered  to the  Company,  other than such notice or
documents required to be delivered to the Warrant Office, shall be delivered at,
or sent by certified or  registered  mail to, the offices of the Company at 3748
Highway #45 North, Columbus,  Mississippi 39701 or such other address within the
continental United States of America as shall have been furnished by the Company
to the holder of this Warrant.

     IV.7  Limitation  of  Liability;  Not  Stockholders.  No  provision of this
Warrant  shall be construed as  conferring  upon the holder  hereof the right to
vote,  consent,  receive  dividends  or receive  notices  (other  than as herein
expressly  provided) in respect of meetings of stockholders  for the election of
directors of the Company or any other matter  whatsoever as a stockholder of the
Company. No provision hereof, in the absence of affirmative action by the holder
hereof to purchase shares of Common Stock, and no mere enumeration herein of the
rights or privileges of the holder  hereof,  shall give rise to any liability of
such  holder  for the  purchase  price of any  shares  of  Common  Stock or as a
stockholder of the Company, whether such liability is asserted by the Company or
by creditors of the Company.


                                       10

satisfactory  to the Company of the loss,  theft,  mutilation or  destruction of
this  Warrant,  and in the case of any such  loss,  theft  or  destruction  upon
delivery of a bond of indemnity  or such other  security in such form and amount

mutilation  upon surrender and  cancellation  of this Warrant,  the Company will
make and  deliver a new  warrant of like  tenor,  in lieu of such lost,  stolen,
destroyed or mutilated Warrant.  Any warrant issued under the provisions of this
Section 4.8 in lieu of any Warrant alleged to be lost,  destroyed or stolen,  or
in lieu of any  mutilated  Warrant,  shall  constitute  an original  contractual
obligation on the part of the Company.  This Warrant shall be promptly  canceled
by the Company  upon the  surrender  hereof in  connection  with any exchange or
replacement.  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  preparation,  execution  and  delivery  of  warrants  pursuant to this
Section 4.8.

     IV.9  Registration  Rights.  The Warrant  Shares  shall be entitled to such
registration  rights  under  the  Securities  Act  and  under  applicable  state
securities laws as are specified in the  Registration  Rights  Agreement and the
Agreement.

     IV.10  Headings.  The Article and Section and other headings herein are for
convenience  only and are not a part of this  Warrant  and shall not  affect the
interpretation thereof.
