                                    ARTICLE I

                              EXERCISE OF WARRANTS

       I.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 23,
2003. 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.

       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.

       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).


                                       3




       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

                                       4





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 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.

              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  December  31,  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


                                       5




              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.

              (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


                                       6





       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

                                       7




       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.

                     (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

                                       8





       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.

       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


                                       9




       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

                                       10




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.

       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


                                       11





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.

                                   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.

                                       12





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

on  the  books  of  the  Company  maintained  at  the  Warrant  Office  for  the
registration  of 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

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.

       IV.8  Exchange,  Loss,  Destruction,  etc.  of Warrant.  Upon  receipt of
evidence  satisfactory  to  the  Company  of  the  loss,  theft,  mutilation  or
destruction  of  this  Warrant,  and in the  case of any  such  loss,  theft  or

form and amount as shall be reasonably  satisfactory  to the Company,  or in the
event of such  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.
