Capital  Stock as result  of a  business  combinations  whereby  Atlas  acquired
various  companies in which the Filing  Persons held  interests.  Such interests
were acquired by each Filing Person with his personal funds.

ITEM 4.     PURPOSE OF TRANSACTION.

     (a)  Prior to April 24,  1998 and the  consummation  of the Share  Exchange
Agreements  described below, (i) Mr. Rigby was the beneficial owner of 1,880,550
shares, or approximately  41%, of the issued and outstanding Atlas Common Stock,
and the  beneficial  owner of  7,616,000  shares,  or 100%,  of the  issued  and
outstanding Atlas Preferred Stock, (ii) Mr. Silverstein was the beneficial owner
of 250,700 shares,  or  approximately  5.5% of the issued and outstanding  Atlas
Common Stock,  and (iii) Mr. Thomas was the beneficial  owner of 250,000 shares,
or approximately 5.5%, of the issued and outstanding Atlas Common Stock.

     Each  Filing  Person   entered  into  a  Share   Exchange   Agreement  with
WasteMasters,  Inc., a Maryland corporation ("WasteMasters"),  dated as of April
23, 1998. The transactions  were closed on April 23, 1998 with final delivery of
stock  certificates  of  WasteMasters  on  April  24,  1998.  WasteMasters  is a
publicly-held  waste management company with an address at 1230 Peachtree Street
N.E.,  Suite  2545,  Atlanta,  Georgia  30309.  Pursuant to the terms of a Share
Exchange   Agreement   dated  as  of  April  23,  1998  between  Mr.  Rigby  and
WasteMasters,  attached  hereto as Exhibit 99.1, Mr. Rigby  exchanged  1,880,550
shares of Atlas Common Stock for 200,000  shares of  WasteMasters  common stock,
$.01 par value ("WasteMasters  Common Stock").  Pursuant to the terms of a Share
Exchange  Agreement  dated as of April 23,  1998  between  Mr.  Silverstein  and
WasteMasters, attached hereto as Exhibit 99.3, Mr. Silverstein exchanged 250,700
shares of Atlas Common Stock for 71,333  shares of  WasteMasters  Common  Stock.
Pursuant to the terms of a Share Exchange Agreement dated April 23, 1998 between
Mr.  Thomas and  WasteMasters,  attached  hereto as  Exhibit  99.4,  Mr.  Thomas
exchanged 250,000 shares of Atlas Common Stock for 71,258 shares of WasteMasters
Common Stock. The parties to the respective Share Exchange Agreements assigned a
value of $3.00 per share to the WasteMasters  Common Stock for purposes of these
transactions, a premium above the then current trading price for publicly traded
stock of  WasteMasters.  The closing price of WasteMasters  Common Stock (NASDAQ
SmallCap) on April 23, 1998 was $2.16.

     Pursuant to the terms of a Share Exchange  Agreement,  dated April 24, 1998
between Mr. Rigby and Waste  Ventures  Corporation,  attached  hereto as Exhibit
99.2,  Mr.  Rigby  exchanged  7,616,000  shares  of Atlas  Preferred  Stock  for
1,385,334  shares of  WasteMasters  Common  Stock,  a two year  Warrant  for the
purchase  of  500,000  shares of  WasteMasters  Common  Stock at $5.00 per share
(Exhibit  99.5) and a two year  Warrant for the  purchase  of 500,000  shares of
WasteMasters Common Stock at $15.00 per share (Exhibit 99.6). Mr. Rigby believes
that Waste Ventures Corporation is not an affiliate of WasteMasters.

     The WasteMasters  Common Stock issued to the Filing Persons pursuant to the
Share Exchange Agreements is not registered under the Securities Act of 1933, as
amended (the "Securities  Act"),  and may not be transferred,  sold or otherwise
disposed of by any Filing  Person except  pursuant to an effective  registration
statement  under the  Securities  Act,  or an  exemption  from the  registration
requirements of the Securities Act.

     The purpose of the transaction  was for  WasteMasters to acquire control of
Atlas.  As a result of the  closing of these  transactions,  the Filing  Persons
transferred  to  WasteMasters  approximately  51% of the issued and  outstanding
shares of voting common stock of Atlas.  The Preferred Stock of Atlas trasferred
by Mr. Rigby was non-voting stock.

     Under the terms of his Share Exchange Agreements, Mr. Rigby has agreed that
he will not,  without the consent of WasteMasters,  transfer,  sell or otherwise
dispose of any shares of  WasteMasters  Common  Stock  issued to him  thereunder
until after the expiration of twelve (12) months following the date of the Share
Exchange Agreements;  and thereafter Mr. Rigby has agreed to sell no more than a
specified  maximum number of shares of WasteMasters  Common Stock per month. Any
public sales by Mr. Rigby must also comply with Rule 144  promulgated  under the
Securities  Act of 1933,  as amended.  In the event that Mr. Rigby wants to sell
more than the specified  maximum amount per month,  WasteMasters or its designee
shall  have a right of first  refusal  to  purchase  the  number  of  shares  of
WasteMasters  Common Stock in excess of such maximum  amount at a discount of 6%
of the bid price on the date such right of first refusal is extended.

     Sub-items (b)-(j) are not applicable.

ITEM 5.     INTEREST IN SECURITIES OF ATLAS.

     (a)-(b)  Following the disposition by the Filing Persons of their shares of
Atlas Common Stock and Atlas  Preferred  Stock,  respectively,  to  WasteMasters
under the terms of the Share Exchange  Agreements each Filing Person has sole or
shared  power to vote or direct the vote of no shares of Atlas  Common  Stock or
any other equity security  issued by Atlas,  and sole or shared power to dispose
or direct the disposition of no shares of Atlas Common Stock or any other equity
security issued by Atlas.

     (c)  Except  as  set  forth  in  Item 4 with  respect  to the  transactions
consummated under the Share Exchange Agreements, no transactions in Atlas Common
Stock were effected by the Filing Persons during the past sixty days.

     (d) Not applicable.

     (e) Each of the Filing Persons  ceased to be the  beneficial  owner of more
than 5% of the issued and outstanding Atlas Common Stock on April 24, 1998.


ITEM 6.     CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH 
            RESPECT TO SECURITIES OF ATLAS.

     Other than as set forth in response to Items 3, 4 and 5 above, there are no
contracts,  arrangements,  understandings or relationships  (legal or otherwise)
among the persons  named in Item 2 above or between  such  persons and any other
person with respect to the  securities  of Atlas,  including but not limited to,
transfer or voting of any of the securities, finder's fees, joint ventures, loan
or option  arrangements,  puts or calls,  guarantees  or profits,  divisions  of
profits or loss, or the giving or withholding of proxies.

     Section 1.5 TRANSFER RESTRICTIONS; LEGEND.

     (a) The shares of WasteMasters Common Stock to be issued to the Stockholder
pursuant to Section 1.3 hereof will not be registered  under the  Securities Act
of 1933, as amended (the  "Securities  Act"), on the Closing Date and may not be
transferred, sold or otherwise disposed of by any Stockholder except pursuant to
an effective  registration  statement  under the Securities Act or in accordance
with an exemption from the  registration  requirements  of the  Securities  Act.
Except as otherwise agreed between the  WasteMasters  and the  Stockholder,  the
Stockholder  agrees that it will not transfer,  sell or otherwise dispose of any
of the shares of WasteMasters Common Stock received or reduce its interest in or

of twelve (12) months  following the Closing;  and  thereafter  the  Stockholder
agrees to sell no more than 10,000 shares of WasteMasters Common Stock per month
and all in accordance with SEC Rule 144. In the event that  Stockholder  desires
to sell more than the specified  lock-up  maximums of 10,000 per month, it shall
grant a first right of refusal to  WasteMasters  or its  designee who shall have
the right, but not the obligation to purchase such shares of WasteMasters Common
Stock in excess of such  maximums  at a  discount  of 6% of the bid price on the
date such right is extended.  After receipt of written  notice from  Stockholder
that he  desires  to sell more than the  specified  monthly  lock-up  maximum of
10,000  shares,  WasteMasters  or its designee  shall have two (2) business days
after  receipt of such  notice to  exercise  such first  right of  refusal.  The
Stockholder may sell the excess shares not purchased by WasteMasters  during the
next 20 business days.

     (b) Each  certificate  representing  shares of  WasteMasters  Common  Stock
issued by  WasteMasters  and delivered by  WasteMasters  to the  Stockholder  in
accordance with Section 1.3 shall bear the following legend:

THE SECURITIES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933 (THE "ACT") AND ARE  "RESTRICTED  SECURITIES" AS THAT
TERM IS DEFINED IN RULE 144 UNDER THE ACT, AND MAY NOT BE SOLD,  TRANSFERRED  OR
OTHERWISE DISPOSED OF BY THE HOLDER EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
STATEMENT  FILED UNDER THE ACT, AS AMENDED,  AND IN COMPLIANCE  WITH  APPLICABLE
SECURITIES  LAWS OF ANY STATE  WITH  RESPECT  THERETO OR IN  ACCORDANCE  WITH AN
OPINION OF  COUNSEL IN FORM AND  SUBSTANCE  SATISFACTORY  TO THE ISSUER  THAT AN
EXEMPTION  FROM  SUCH  REGISTRATION  IS  AVAILABLE  AND  ALSO  MAY NOT BE  SOLD,
TRANSFERRED OR OTHERWISE  DISPOSED OF BY THE HOLDER WITHOUT  COMPLIANCE WITH THE
APPLICABLE SECURITIES AND EXCHANGE COMMISSION RULES AND REGULATIONS.

WasteMasters agrees to remove such legend (or any relevant portion thereof),  by
prompt delivery of substitute  certificates upon the request of the holder if at
such time such legend (or portion  thereof) is no longer  required  for purposes
of, or applicable pursuant to, the prior provisions of this Section 1.5.

exchange of shares of Company  Common Stock in accordance  with the terms hereof
shall  be  deemed  to have  been  issued  in  full  satisfaction  of all  rights
pertaining to such shares of Company Common Stock.

     Upon the terms and  subject  to the  conditions  of this  Agreement,  Waste

validly issued,  fully paid and  nonassessable  Rule 144 restricted common stock

share in exchange  for shares of Company  Preferred  Stock  conveyed,  assigned,
transferred  and  delivered to Waste  Ventures by such  Stockholder  pursuant to

combination,  exchange of shares or similar transaction, the Preferred Stock Per
Share  Consideration  shall be  correspondingly  adjusted to reflect  such stock
dividend, subdivision,  reclassification,  recapitalization, split, combination,

preceding  sentence  shall be  construed  as  providing  the  holders of Company
Preferred Stock any preemptive or antidilutive rights.

     Section 1.5 TRANSFER RESTRICTIONS; LEGEND.

     (a) The shares of WasteMasters Common Stock to be issued to the Stockholder
pursuant to Section 1.3 hereof will not be registered  under the  Securities Act
of 1933, as amended (the  "Securities  Act"), on the Closing Date and may not be
transferred, sold or otherwise disposed of by any Stockholder except pursuant to
an effective  registration  statement  under the Securities Act or in accordance
with an exemption from the  registration  requirements  of the  Securities  Act.
Except  as  otherwise  agreed  between  WasteMasters  and the  Stockholder,  the
Stockholder  agrees that it will not transfer,  sell or otherwise dispose of any
of the shares of WasteMasters Common Stock received or reduce its interest in or
relating to such shares of WasteMasters  Common Stock until after the expiration
of twelve (12) months  following the Closing;  and  thereafter  the  Stockholder
agrees to sell no more than 40,000 shares of WasteMasters Common Stock per month
and all in accordance with SEC Rule 144. In the event that  Stockholder  desires
to sell more than the specified  lock-up  maximums of 40,000 per month, it shall
grant a first right of refusal to Waste  Ventures or its designee who shall have
the right, but not the obligation to purchase such shares of WasteMasters Common
Stock in excess of such  maximums  at a  discount  of 6% of the bid price on the
date such right is extended.  After receipt of written  notice from  Stockholder
that he  desires  to sell more than the  specified  monthly  lock-up  maximum of
40,000  shares,  Waste Ventures or its designee shall have two (2) business days
after  receipt of such  notice to  exercise  such first  right of  refusal.  The
Stockholder  may sell the excess shares not purchased by Waste  Ventures  during
the next 20 business days.

     (b) Each  certificate  representing  shares of  WasteMasters  Common  Stock
issued by  WasteMasters  and delivered by Waste  Ventures to the  Stockholder in
accordance with Section 1.3 shall bear the following legend:

     THE SECURITIES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT BEEN  REGISTERED
UNDER THE SECURITIES ACT OF 1933 (THE "ACT") AND ARE "RESTRICTED  SECURITIES" AS
THAT TERM IS DEFINED IN RULE 144 UNDER THE ACT, AND MAY NOT BE SOLD, TRANSFERRED
OR  OTHERWISE  DISPOSED  OF BY  THE  HOLDER  EXCEPT  PURSUANT  TO  AN  EFFECTIVE
REGISTRATION  STATEMENT FILED UNDER THE ACT, AS AMENDED,  AND IN COMPLIANCE WITH
APPLICABLE  SECURITIES  LAWS OF ANY STATE WITH RESPECT  THERETO OR IN ACCORDANCE
WITH AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER THAT
AN  EXEMPTION  FROM SUCH  REGISTRATION  IS  AVAILABLE  AND ALSO MAY NOT BE SOLD,
TRANSFERRED OR OTHERWISE  DISPOSED OF BY THE HOLDER WITHOUT  COMPLIANCE WITH THE
APPLICABLE SECURITIES AND EXCHANGE COMMISSION RULES AND REGULATIONS.

Waste  Ventures  agrees to cause  WasteMasters  to remove  such  legend  (or any
relevant portion  thereof),  by prompt delivery of substitute  certificates upon
the request of the holder if at such time such legend (or portion thereof) is no
longer required for purposes of, or applicable pursuant to, the prior provisions
of this Section 1.5.

WASTEMASTERS,  INC., a Maryland  corporation (the "COMPANY") hereby grants to T.
ALEC RIGBY, an individual (hereinafter the "Holder"), a Warrant to purchase FIVE
HUNDRED THOUSAND (500,000)  restricted shares (the "Shares") of the common stock
of the  Company  (the  "Common  Stock") at the  purchase  price of Five  Dollars
($5.00) per Share (the  "Exercise  Price")  (the  number of Shares and  Exercise
Price being subject to adjustment,  as hereinafter  provided) upon the terms and
conditions herein set forth.

     1. EXERCISE OF WARRANT.

          (a) Subject to  subsection  (b) of this Section 1, this Warrant may be
exercised upon presentation and surrender of this Warrant Certificate,  with the
attached Purchase Form (Exhibit A) duly executed, at the principal office of the
Company,  at 10254 Miller Road,  Dallas,  Texas 75238, or at such other place as
the Company may  designate  by notice to the Holder,  together  with a certified
bank or cashier's check payable to the order of WasteMasters, Inc. in the amount
of the Exercise Price times the number of Shares being  purchased.  This Warrant
may be exercised in whole or in part.  In case of exercise  hereof in part only,
the Company,  upon  surrender  hereof,  will deliver to the Holder a new Warrant
Certificate of like tenor  entitling the Holder to purchase the number of Shares
as to which this Warrant has not been exercised.

          (b) This Warrant to purchase the  "unregistered,"  "restricted" common
stock of the Company may be  exercised  in whole or in part at any time prior to
5:00 o'clock p.m., Dallas, Texas time on April 23, 2000.

     2. PURCHASED AND UNDERLYING SHARES.

          (a) Upon  surrender  of this  Warrant  Certificate  and payment of the
Exercise  Price as aforesaid,  the Company shall issue and cause to be delivered
with all reasonable  dispatch to the Holder,  a certificate or certificates  for
the number of full shares of Common Stock  comprising the  applicable  number of
Shares so purchased upon the exercise of this Warrant (the "Purchased  Shares"),
together  with  cash,  as  provided  in  Section 9  hereof,  in  respect  of any
fractional  Shares otherwise  issuable upon such surrender.  Such certificate or
certificates  shall be deemed to have been issued,  and any person named therein
shall be deemed to have become a holder of record of such Shares, as of the date
of surrender of this Warrant and payment of the Exercise  Price,  as  aforesaid,
notwithstanding  that  the  certificates  representing  such  Shares  shall  not
actually have been  delivered or that the transfer shall not have been reflected
on the stock transfer books of the Company.

          (b) The  Company  shall at all  times  keep  reserved  so long as this
Warrant remains outstanding,  out of its authorized shares of Common Stock, such
number of Shares as shall  continue to be subject to purchase under this Warrant
(the  "Underlying  Shares").  Every transfer agent for the Common Stock issuable
upon the exercise of this Warrant shall be  irrevocably  authorized and directed
at all times to reserve such number of  authorized  Shares as shall be requisite
for such purpose.

     3. RIGHTS AND OBLIGATIONS OF WARRANT HOLDER.

          (a) The  Holder  of this  Warrant  shall  not,  by virtue  hereof,  be
entitled  to any rights of a  shareholder  in the  Company,  either at law or in
equity.  The rights of the Holder of this Warrant are limited to those expressed
herein and the Holder of this Warrant, by its acceptance hereof, consents to and
agrees  to be bound by and to comply  with all the  provisions  of this  Warrant
Certificate, including, without limitation, all the obligations imposed upon the
Holder by Section 5 hereof.

          (b) The Holder of this Warrant, as such, shall not be entitled to vote
or receive  dividends or to be deemed the holder of Shares for any purpose,  nor
shall anything contained in this Warrant  Certificate,  as such, confer upon the
Holder any of the rights of a  shareholder  of the  Company  including,  but not
limited  to, any right to vote,  give or  withhold  consent to any action by the
Company, whether upon any recapitalization,  issue of stock, reclassification of
stock, consolidation,  merger, share exchange,  conveyance or otherwise, receive
notice of  meetings  or other  action  affecting  shareholders  (except  for the
notices provided for herein), receive dividends, receive subscription rights, or
any other  right until this  Warrant  shall have been  exercised  and the Holder
shall have become the record holder of the Shares, as provided herein.

     4. PURCHASED  SHARES.  The Company  covenants and agrees that all Purchased
Shares to be delivered upon proper exercise of this Warrant shall be recorded on
the books of the Company in the name of the Holder and shall be duly and validly
authorized  and  issued,  fully  paid  and  non-assessable,  and  free  from all
preemptive  rights,  taxes  (other  than  transfer  taxes),  liens,  charges and
security interests created by the Company with respect to the issuance thereof.

     5. DISPOSITION OF WARRANTS OR SHARES.

          (a) The Holder of this Warrant and/or any transferee  hereof or of the
Purchased  Shares by its acceptance  hereof or thereof,  hereby  understands and
agrees that neither this Warrant nor the Purchased  Shares have been  registered
under either the 1933 Act or applicable state securities laws (the "State Acts")
and shall not be sold, pledged,  hypothecated,  donated or otherwise transferred
(whether or not for consideration)  except upon the issuance to the Company of a
favorable  opinion of counsel or  submission  to the Company of such evidence as
may be reasonably  satisfactory to counsel to the Company, in each such case, to
the effect that any such transfer  shall not be in violation of the 1933 Act and
the State Acts. It shall be a condition to the transfer of this Warrant that any
transferee  hereof deliver to the Company its written agreement to accept and be
bound  by all of the  representations,  terms  and  conditions  of this  Warrant
Certificate.  This  Warrant  shall not be  assignable  except  upon the  express
written consent of the Company.

          (b) The stock  certificates  of the  Company  that will  evidence  the
Purchased Shares may be imprinted with a conspicuous legend in substantially the
following form:

THE SECURITIES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933 (THE "ACT") AND ARE  "RESTRICTED  SECURITIES" AS THAT
TERM IS DEFINED IN RULE 144 UNDER THE ACT, AND MAY NOT BE SOLD,  TRANSFERRED  OR
OTHERWISE DISPOSED OF BY THE HOLDER EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
STATEMENT  FILED UNDER THE ACT, AS AMENDED,  AND IN COMPLIANCE  WITH  APPLICABLE
SECURITIES  LAWS OF ANY STATE  WITH  RESPECT  THERETO OR IN  ACCORDANCE  WITH AN
OPINION OF  COUNSEL IN FORM AND  SUBSTANCE  SATISFACTORY  TO THE ISSUER  THAT AN
EXEMPTION  FROM  SUCH  REGISTRATION  IS  AVAILABLE  AND  ALSO  MAY NOT BE  SOLD,
TRANSFERRED OR OTHERWISE  DISPOSED OF BY THE HOLDER WITHOUT  COMPLIANCE WITH THE
APPLICABLE SECURITIES AND EXCHANGE COMMISSION RULES AND REGULATIONS.

            The Company has not agreed to register any of the  Purchased  Shares
for  distribution in accordance with the provisions of the 1933 Act or the State
Acts. Except as otherwise set forth herein, the Company has not agreed to comply
with any exemption  from  registration  under the 1933 Act or the State Acts for
the resale of such Shares.  Hence, it is the understanding of the Holder that by
virtue of the  provisions of certain rules  respecting  "restricted  securities"
promulgated by the U.S. Securities and Exchange  Commission,  all or part of the
Purchased  Shares  may be  required  to be held  indefinitely,  unless and until
registered  under the 1933 Act and the State Acts,  or unless an exemption  from
such registration is available (in which case the Holder may still be limited as
to the number of such Shares that may be sold).

     6. REPRESENTATIONS.

          (a) RISK FACTORS.  The Holder  understands and  acknowledges  that (i)
this Warrant and the Purchased Shares are  unregistered,  restricted  securities
and  are not  readily  marketable,  (ii)  the  Company  has  not  operated  on a
profitable  basis for several  years and that there can be no assurance  that it
will operate  profitably in the future,  and (iii) there is a significant degree
of risk in  investing in the Shares.  The Holder  agrees that he must be able to
bear the economic risk of the loss of the entire  investment in the Shares if he
exercises this Warrant.

          (b) KNOWLEDGE AND EXPERIENCE;  FINANCIAL CAPABILITY AND NET WORTH. The
Holder has (i) such knowledge and  experience in financial and business  matters
that he is capable of evaluating  the merits and risks of the  investment in the
Shares, (ii) had such risks explained to the Holder and has determined that such
investment is suitable for the Holder in view of his financial circumstances and
available  investment  opportunities,  (iii)  sufficient net worth and income to
bear the economic risk of investment in the Purchased  Shares,  and (iv) no need
for liquidity of the  investment  and no reason to anticipate  any change in the
Holder's financial  circumstances  which may cause or require any sale, transfer
or other distribution of the Purchased Shares.

          (c) AVAILABLE  INFORMATION.  The Holder  acknowledges that the Company
has provided him with access to such Company records and  information  regarding
historical and proposed  operations as the Holder has requested and has answered
all of the Holder's inquiries in full.

          (d)  FURTHER  INFORMATION.  The  Holder  agrees  that it  shall be his
responsibility to request such information with respect to the Company as he and
his advisors deem  appropriate to evaluate the risks and merits of investment in
the Purchased Shares at the time that the Holder exercises this Warrant.

     7. ADJUSTMENTS.  The number of Shares purchasable upon the exercise of this
Warrant,  and the Exercise  Price,  shall be subject to adjustment  from time to
time upon the occurrence of any of the events enumerated below at any time prior
to the exercise of this Warrant in full.

          (a)  In  case  the  Company  shall:  (i)  pay a  dividend,  or  make a
distribution  on the Common Stock, in shares of Common Stock or any other of its
capital  stock,  (ii)  subdivide its  outstanding  shares of Common Stock into a
greater number of shares of Common Stock,  (iii) combine its outstanding  shares
of its capital stock into a smaller  number of shares of Common  Stock,  or (iv)
issue, by  reclassification of its shares of Common Stock, any shares of capital
stock  (including any  reclassification  in connection with a  consolidation  or
merger in which the Company is the continuing corporation), the amount of Shares
purchasable upon the exercise of this Warrant immediately prior thereto shall be
adjusted so that the Holder shall be entitled to receive  upon  exercise of this
Warrant that number of Shares (or other capital stock of the Company)  which the
Holder  would  have  owned or would  have been  entitled  to  receive  after the
happening of such event had the Holder exercised this Warrant  immediately prior
to the record date, in the case of any such dividend,  or the effective date, in
the case of any such subdivision, combination or reclassification. An adjustment
made pursuant to this  subsection  (a) shall be made whenever any of such events
shall occur, but shall become effective  retroactively after such record date or
such  effective  date,  as the case may be, as to any  portion  of this  Warrant
exercised  between such record date or effective  date and the date of happening
of any such event.

          (b) If the Company shall issue, by reorganization or  reclassification
of its Common Stock (including any such  reorganization or  reclassification  in
connection  with  a  consolidation   or  merger  of  the  Company  with  another
corporation, provided the Company is the surviving corporation) other securities
or  property  of the  Company,  the Holder  shall  thereafter  have the right to
receive upon  exercise of this Warrant the kind and number of shares of stock or
other  securities or property  which he would have been entitled to receive upon
the happening of any such reorganization or  reclassification,  had this Warrant
been  exercised  immediately  prior  thereto;  and,  in  any  case,  appropriate
adjustment (as determined by the Board of Directors in good faith) shall be made
in the application of the provisions herein set forth with respect to rights and
interests  thereafter of the Holder,  to the end that the  provisions  set forth
herein shall  thereafter  be  applicable,  as near as reasonably  practical,  in
relation to any shares of stock or other securities or other property thereafter
deliverable  upon the exercise of this Warrant.  Any adjustment made pursuant to
this subparagraph (b) shall become effective retroactively to the effective date
of such reorganization or reclassification.

          (c) If the Company  shall issue,  sell,  grant or distribute to all or
substantially  all holders of shares of Common Stock evidences of  indebtedness,
any other  securities of the Company  (including,  without  limitation,  rights,
Warrants,  warrants or  convertible  or  exchangeable  securities  entitling the
holders thereof to subscribe for,  purchase,  or convert or exchange  securities
into,  shares of Common Stock,  whether or not  immediately  exercisable) or any
property or other assets (other than cash), and if such issuance, sale, grant or
distribution does not otherwise  constitute an event requiring  adjustment under
this  Section 7 (any such  nonexcluded  event  being  herein  called a  "Special
Dividend"),  then,  effective upon the record date of the Special Dividend,  the
Holder  shall be entitled to receive,  upon  exercise of this  Warrant  (and the
payment of the  consideration,  if any,  payable to the Company for such Special
Dividend  under the terms of its issuance,  sale,  grant or  distribution),  the
Special  Dividend  which the Holder would have been  entitled to receive if this
Warrant had been exercised  immediately  prior to the record date of the Special
Dividend.

          (d) In case the Company  shall make a  distribution  to all holders of
the  Common  Stock  of  stock  of a  subsidiary  of the  Company  or  securities
convertible into or exercisable for such stock, then in lieu of an adjustment in
the Exercise Price or the number of Shares  purchasable upon the exercise of the
Warrant,  the Holder,  upon the  exercise of this Warrant at any time after such
distribution,  shall be entitled to receive from the Company, such subsidiary or
both, as the Company  shall  determine,  the stock or other  securities to which
such Holder would have been entitled if such Holder had  exercised  this Warrant
immediately prior thereto, all subject to further adjustment as provided in this
Section 7, and the Company shall  reserve,  for the life of this  Warrant,  such
securities of such subsidiary.

          (e) If there shall be any consolidation or merger to which the Company
is a party,  other than a  consolidation  or a merger in which the  Company is a
continuing  corporation and which does not result in any reclassification of, or
change (other than a change in respect of which an adjustment is required  under
any other provision of this Section 7 or a change in par value) in,  outstanding
shares of Common Stock, or any sale or conveyance of the property of the Company
as an entirety or  substantially  as an entirety  (any such event being called a
"Capital  Reorganization"),  then,  effective  upon the  effective  date of such
Capital  Reorganization,  the  Holder  shall  have the right to  purchase,  upon
exercise  of this  Warrant,  the kind and  amount  of  shares of stock and other
securities  and property  (including  cash) which the Holder would have owned or
have been entitled to receive after such Capital  Reorganization if this Warrant
had been exercised  immediately prior to such Capital  Reorganization  (assuming
the Holder failed to exercise his rights of election,  if any, as to the kind or
amount of  securities,  cash or other  property  receivable  upon  such  Capital
Reorganization).  As a condition to effecting  any Capital  Reorganization,  the
Company or the  successor  or surviving  corporation,  as the case may be, shall
execute  and  deliver to the Holder and to the  Company an  agreement  as to the
Holder's  rights in accordance  with this Section 7,  providing  for  subsequent
adjustments  as  nearly  equivalent  as may be  practicable  to the  adjustments
provided  for in this  Section  7. The  provisions  of this  subparagraph  shall
similarly apply to successive Capital Reorganizations.

          (f)  After  any  adjustment  of the  number or kind of shares or other
securities or property  issuable  upon exercise of this Warrant  pursuant to the
provisions  of this Section,  the Exercise  Price shall also be adjusted so that
the aggregate  Exercise Price  thereafter  payable upon exercise of this Warrant
shall be equal to the  aggregate  Exercise  Price which would have been  payable
upon exercise of this Warrant immediately prior to such adjustment.

          (g) No  adjustment  shall be  required  unless such  adjustment  would
require an increase  or  decrease of at least one percent  (1%) in the number of
the Underlying Shares;  provided,  however, that any adjustments which by reason
of this  subsection  are not  required  to be made shall be carried  forward and
taken into account in any subsequent  adjustment.  All  calculations  under this
Section 7 shall be made to the nearest one-hundredth of a Share.

          (h) Whenever the number of Shares purchasable hereunder is adjusted as
herein  provided,  the  Company  shall  cause  to be  mailed  to the  Holder  in
accordance  with the  provisions  of this  Section a notice (i) stating that the
number of Shares  purchasable  upon exercise of this Warrant has been  adjusted,
(ii) setting forth the adjusted number of Underlying Shares, (iii) setting forth
the  adjusted  Exercise  Price,  and  (iv)  showing  in  reasonable  detail  the
computations  and the  facts,  including  the amount of  consideration,  if any,
received  or  deemed to have been  received  by the  Company,  upon  which  such
adjustments are based.  Such notice shall be conclusive as to the correctness of
the adjustment of the Underlying Shares and Exercise Price unless objected to by
the Holder  within 30 days  following the receipt of such notice by such Holder.
If the  Holder  objects  to the  adjustment  as  set  forth  in  such  notice  a
representative  of the  Company  shall  meet with the  Holder  at such  mutually
convenient time or times as shall be mutually acceptable to the parties in order
to agree as to the correct adjustment.  If the Company and the Holder are unable
to agree as to the correctness of the adjustment,  the matter shall be submitted
to a mutually acceptable firm of independent certified public accountants, whose
determination as to the correct  adjustment shall be conclusive and binding upon
the Company and the Holder.

          (i) The Company shall cause written notice of any Special  Dividend to
be mailed to the Holder at the earliest practicable time (and, in any event, not
less than 10 days  before the date fixed as a record date or the date of closing
the transfer books for the  determination of the  shareholders  entitled to such
Special Dividend.)

     8. LIQUIDATION OR DISSOLUTION. In case the Company dissolves or liquidates,
the Company shall make appropriate provision so that the securities or property,
as the case may be,  which would be received by the Holder upon the  exercise of
this  Warrant  at the  time  immediately  prior  to the  effective  date of such
dissolution or liquidation, will be available to the Holder from the liquidating
trust;  provided that the Holder shall make the  determination  as to whether to
exercise this Warrant  within six months of the effective date of dissolution or
liquidation,  at which time this Warrant shall be  terminated  and of no further
force  or  effect  and  the  Holder's   rights  under  this  Warrant   shall  be
automatically terminated.

     9.  FRACTIONAL  SHARES.  No  fraction  of a Share  shall be  required to be
delivered  upon the  exercise  of this  Warrant or any  portion  hereof.  If any
fractional  interest in a Share shall be  deliverable  upon the exercise of this
Warrant,  the Company  shall make an  adjustment  therefor in cash equal to such
fraction  multiplied  by the Current  Market Price of the Shares on the business
day next  preceding  the day of  exercise.  For  purposes of this  Warrant,  the
"Current Market Price" per share of Common Stock at any date shall be (i) if the
shares of Common Stock are listed on any national securities exchange, the daily
closing price on the date of  determination;  (ii) if the shares of Common Stock
are not listed on any national securities exchange but are quoted or reported on
the National Association of Securities Dealers, Inc., Automated Quotation System
("NASDAQ"), the last quoted price or, if not quoted, the average of the high bid
and low asked price as reported by NASDAQ,  as the case may be; and (iii) if the
shares of Common Stock are neither  listed on any national  securities  exchange
nor quoted or reported on NASDAQ, the closing bid price in the  over-the-counter
market as furnished by any NASDAQ member firm that is selected from time to time
by the Company.

     10. NO IMPAIRMENT.  The Company shall not by any action including,  without
limitation,   amending  its   certificate  of   incorporation   or  through  any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities  or any other  voluntary  action,  avoid or seek to avoid the
observance or performance  of any of the terms of this Warrant,  but will at all
times in good  faith  assist in the  carrying  out of all such  terms and in the
taking of all such  actions as may be necessary  or  appropriate  to protect the
rights of the Holder against impairment.  Without limiting the generality of the
foregoing,  the  Company  will (a) not  increase  the par value of any shares of
Common  Stock  receivable  upon the  exercise of this  Warrant  above the amount
payable  therefor upon such exercise  immediately  prior to such increase in par
value,  and (b) take all such action as may be necessary or appropriate in order
that the Company may  validly  and  legally  issue fully paid and  nonassessable
shares of Common Stock upon the exercise of this Warrant.

     11. REMEDIES. The Company stipulates that the remedies at law of the Holder
in the  event  of any  default  or  threatened  default  by the  Company  in the
performance  of or compliance  with any of the terms of this Warrant are not and
will not be adequate and that,  without  limiting any other remedy  available at
law,  such  terms may be  specifically  enforced  by a decree  for the  specific
performance  of any agreement  contained  herein or by an  injunction  against a
violation of any of the terms hereof.  The rights and remedies of the Holder are
cumulative  and not  exclusive of any rights or remedies  which the Holder might
otherwise have.

     12.  LOSS OR  DESTRUCTION.  Upon  receipt of evidence  satisfactory  to the
Company  of  the  loss,  theft,   mutilation  or  destruction  of  this  Warrant
Certificate,  the Company shall,  upon its receipt of an indemnity  agreement or
bond reasonably satisfactory in form, substance and amount to the Company or, in
the case of any such mutilation, upon surrender and cancellation of this Warrant
Certificate,  the Company at its expense will execute and deliver to the Holder,
in lieu thereof, a new Warrant Certificate of like tenor.

     13.  SURVIVAL.  The various rights and  obligations of the Holder hereof as
set forth herein shall  survive the exercise of this Warrant at any time or from
time to time and the surrender of this Warrant Certificate.

     14.  NOTICES.  Whenever any notice,  payment of any purchase price or other
communication (any such notice, payment or other communication, a "Delivery") is
required to be given or delivered  under the terms of this Warrant,  it shall be
in writing and  delivered by hand  delivery or Federal  Express or registered or
certified United States mail, postage prepaid and return receipt requested,  and
will be deemed to have been given or delivered on the date such notice, purchase
price or other communication is so delivered. Any Delivery to the Company, shall
be addressed to 10254 Miller Road, Dallas, Texas 75238, or to such other address
as the Company may hereafter designate to the Holder in writing; any Delivery to
the Holder  shall be  addressed  to such  address  as the  Holder may  hereafter
designate to the Company in writing.

     15.  CHANGE;  WAIVER.  Neither  this  Warrant  nor any term  hereof  may be
changed,  waived,  discharged or terminated orally, but only by an instrument in
writing  signed by the party against which  enforcement  of the change,  waiver,
discharge  or  termination  is  sought.  No  failure  or delay of the  Holder in
exercising any power or right hereunder  shall operate as a waiver thereof,  nor
shall  any  single  or  partial  exercise  of any such  right or  power,  or any
abandonment  or  discontinuance  of steps  to  enforce  such a right  or  power,
preclude  any other or further  exercise  thereof or the  exercise  of any other
right or power.

     16.  COVENANTS TO BIND  SUCCESSOR  AND  ASSIGNS.  The terms of this Warrant
shall bind the successors and permitted assigns of the Holder and the Company.

     17.  SEVERABILITY.  In case any one or more of the provisions  contained in
this Warrant  shall be invalid,  illegal or  unenforceable  in any respect,  the
validity,  legality or  enforceability  of the  remaining  provisions  contained
herein shall not in any way be affected or impaired  thereby.  The parties shall
endeavor  in  good  faith  negotiations  to  replace  the  invalid,  illegal  or
unenforceable  provisions  with valid  provisions  the economic  effect of which
comes as close as  possible  to that of the  invalid,  illegal or  unenforceable
provisions.

                       Dallas, Texas Time, April 23, 2000


WASTEMASTERS,  INC., a Maryland  corporation (the "COMPANY") hereby grants to T.
ALEC RIGBY, an individual (hereinafter the "Holder"), a Warrant to purchase FIVE
HUNDRED THOUSAND (500,000)  restricted shares (the "Shares") of the common stock
of the Company (the "Common  Stock") at the  purchase  price of Fifteen  Dollars
($15.00)  per Share (the  "Exercise  Price")  (the number of Shares and Exercise
Price being subject to adjustment,  as hereinafter  provided) upon the terms and
conditions herein set forth.

     1. EXERCISE OF WARRANT.

          (a) Subject to  subsection  (b) of this Section 1, this Warrant may be
exercised upon presentation and surrender of this Warrant Certificate,  with the
attached Purchase Form (Exhibit A) duly executed, at the principal office of the
Company,  at 10254 Miller Road,  Dallas,  Texas 75238, or at such other place as
the Company may  designate  by notice to the Holder,  together  with a certified
bank or cashier's check payable to the order of WasteMasters, Inc. in the amount
of the Exercise Price times the number of Shares being  purchased.  This Warrant
may be exercised in whole or in part.  In case of exercise  hereof in part only,
the Company,  upon  surrender  hereof,  will deliver to the Holder a new Warrant
Certificate of like tenor  entitling the Holder to purchase the number of Shares
as to which this Warrant has not been exercised.

          (b) This Warrant to purchase the  "unregistered,"  "restricted" common
stock of the Company may be  exercised  in whole or in part at any time prior to
5:00 o'clock p.m., Dallas, Texas time on April 23, 2000.

     2. PURCHASED AND UNDERLYING SHARES.

          (a) Upon  surrender  of this  Warrant  Certificate  and payment of the
Exercise  Price as aforesaid,  the Company shall issue and cause to be delivered
with all reasonable  dispatch to the Holder,  a certificate or certificates  for
the number of full shares of Common Stock  comprising the  applicable  number of
Shares so purchased upon the exercise of this Warrant (the "Purchased  Shares"),
together  with  cash,  as  provided  in  Section 9  hereof,  in  respect  of any
fractional  Shares otherwise  issuable upon such surrender.  Such certificate or
certificates  shall be deemed to have been issued,  and any person named therein
shall be deemed to have become a holder of record of such Shares, as of the date
of surrender of this Warrant and payment of the Exercise  Price,  as  aforesaid,
notwithstanding  that  the  certificates  representing  such  Shares  shall  not
actually have been  delivered or that the transfer shall not have been reflected
on the stock transfer books of the Company.

          (b) The  Company  shall at all  times  keep  reserved  so long as this
Warrant remains outstanding,  out of its authorized shares of Common Stock, such
number of Shares as shall  continue to be subject to purchase under this Warrant
(the  "Underlying  Shares").  Every transfer agent for the Common Stock issuable
upon the exercise of this Warrant shall be  irrevocably  authorized and directed
at all times to reserve such number of  authorized  Shares as shall be requisite
for such purpose.

     3. RIGHTS AND OBLIGATIONS OF WARRANT HOLDER.

          (a) The  Holder  of this  Warrant  shall  not,  by virtue  hereof,  be
entitled  to any rights of a  shareholder  in the  Company,  either at law or in
equity.  The rights of the Holder of this Warrant are limited to those expressed
herein and the Holder of this Warrant, by its acceptance hereof, consents to and
agrees  to be bound by and to comply  with all the  provisions  of this  Warrant
Certificate, including, without limitation, all the obligations imposed upon the
Holder by Section 5 hereof.

          (b) The Holder of this Warrant, as such, shall not be entitled to vote
or receive  dividends or to be deemed the holder of Shares for any purpose,  nor
shall anything contained in this Warrant  Certificate,  as such, confer upon the
Holder any of the rights of a  shareholder  of the  Company  including,  but not
limited  to, any right to vote,  give or  withhold  consent to any action by the
Company, whether upon any recapitalization,  issue of stock, reclassification of
stock, consolidation,  merger, share exchange,  conveyance or otherwise, receive
notice of  meetings  or other  action  affecting  shareholders  (except  for the
notices provided for herein), receive dividends, receive subscription rights, or
any other  right until this  Warrant  shall have been  exercised  and the Holder
shall have become the record holder of the Shares, as provided herein.

     4. PURCHASED  SHARES.  The Company  covenants and agrees that all Purchased
Shares to be delivered upon proper exercise of this Warrant shall be recorded on
the books of the Company in the name of the Holder and shall be duly and validly
authorized  and  issued,  fully  paid  and  non-assessable,  and  free  from all
preemptive  rights,  taxes  (other  than  transfer  taxes),  liens,  charges and
security interests created by the Company with respect to the issuance thereof.

     5. DISPOSITION OF WARRANTS OR SHARES.

          (a) The Holder of this Warrant and/or any transferee  hereof or of the
Purchased  Shares by its acceptance  hereof or thereof,  hereby  understands and
agrees that neither this Warrant nor the Purchased  Shares have been  registered
under either the 1933 Act or applicable state securities laws (the "State Acts")
and shall not be sold, pledged,  hypothecated,  donated or otherwise transferred
(whether or not for consideration)  except upon the issuance to the Company of a
favorable  opinion of counsel or  submission  to the Company of such evidence as
may be reasonably  satisfactory to counsel to the Company, in each such case, to
the effect that any such transfer  shall not be in violation of the 1933 Act and
the State Acts. It shall be a condition to the transfer of this Warrant that any
transferee  hereof deliver to the Company its written agreement to accept and be
bound  by all of the  representations,  terms  and  conditions  of this  Warrant
Certificate.  This  Warrant  shall not be  assignable  except  upon the  express
written consent of the Company.

          (b) The stock  certificates  of the  Company  that will  evidence  the
Purchased Shares may be imprinted with a conspicuous legend in substantially the
following form:

THE SECURITIES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933 (THE "ACT") AND ARE  "RESTRICTED  SECURITIES" AS THAT
TERM IS DEFINED IN RULE 144 UNDER THE ACT, AND MAY NOT BE SOLD,  TRANSFERRED  OR
OTHERWISE DISPOSED OF BY THE HOLDER EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
STATEMENT  FILED UNDER THE ACT, AS AMENDED,  AND IN COMPLIANCE  WITH  APPLICABLE
SECURITIES  LAWS OF ANY STATE  WITH  RESPECT  THERETO OR IN  ACCORDANCE  WITH AN
OPINION OF  COUNSEL IN FORM AND  SUBSTANCE  SATISFACTORY  TO THE ISSUER  THAT AN
EXEMPTION  FROM  SUCH  REGISTRATION  IS  AVAILABLE  AND  ALSO  MAY NOT BE  SOLD,
TRANSFERRED OR OTHERWISE  DISPOSED OF BY THE HOLDER WITHOUT  COMPLIANCE WITH THE
APPLICABLE SECURITIES AND EXCHANGE COMMISSION RULES AND REGULATIONS.

     The  Company  has not agreed to register  any of the  Purchased  Shares for
distribution  in  accordance  with the  provisions  of the 1933 Act or the State
Acts. Except as otherwise set forth herein, the Company has not agreed to comply
with any exemption  from  registration  under the 1933 Act or the State Acts for
the resale of such Shares.  Hence, it is the understanding of the Holder that by
virtue of the  provisions of certain rules  respecting  "restricted  securities"
promulgated by the U.S. Securities and Exchange  Commission,  all or part of the
Purchased  Shares  may be  required  to be held  indefinitely,  unless and until
registered  under the 1933 Act and the State Acts,  or unless an exemption  from
such registration is available (in which case the Holder may still be limited as
to the number of such Shares that may be sold).

     6. REPRESENTATIONS.

          (a) RISK FACTORS.  The Holder  understands and  acknowledges  that (i)
this Warrant and the Purchased Shares are  unregistered,  restricted  securities
and  are not  readily  marketable,  (ii)  the  Company  has  not  operated  on a
profitable  basis for several  years and that there can be no assurance  that it
will operate  profitably in the future,  and (iii) there is a significant degree
of risk in  investing in the Shares.  The Holder  agrees that he must be able to
bear the economic risk of the loss of the entire  investment in the Shares if he
exercises this Warrant.

          (b) KNOWLEDGE AND EXPERIENCE;  FINANCIAL CAPABILITY AND NET WORTH. The
Holder has (i) such knowledge and  experience in financial and business  matters
that he is capable of evaluating  the merits and risks of the  investment in the
Shares, (ii) had such risks explained to the Holder and has determined that such
investment is suitable for the Holder in view of his financial circumstances and
available  investment  opportunities,  (iii)  sufficient net worth and income to
bear the economic risk of investment in the Purchased  Shares,  and (iv) no need
for liquidity of the  investment  and no reason to anticipate  any change in the
Holder's financial  circumstances  which may cause or require any sale, transfer
or other distribution of the Purchased Shares.

          (c) AVAILABLE  INFORMATION.  The Holder  acknowledges that the Company
has provided him with access to such Company records and  information  regarding
historical and proposed  operations as the Holder has requested and has answered
all of the Holder's inquiries in full.

          (d)  FURTHER  INFORMATION.  The  Holder  agrees  that it  shall be his
responsibility to request such information with respect to the Company as he and
his advisors deem  appropriate to evaluate the risks and merits of investment in
the Purchased Shares at the time that the Holder exercises this Warrant.

     7. ADJUSTMENTS.  The number of Shares purchasable upon the exercise of this
Warrant,  and the Exercise  Price,  shall be subject to adjustment  from time to
time upon the occurrence of any of the events enumerated below at any time prior
to the exercise of this Warrant in full.

          (a)  In  case  the  Company  shall:  (i)  pay a  dividend,  or  make a
distribution  on the Common Stock, in shares of Common Stock or any other of its
capital  stock,  (ii)  subdivide its  outstanding  shares of Common Stock into a
greater number of shares of Common Stock,  (iii) combine its outstanding  shares
of its capital stock into a smaller  number of shares of Common  Stock,  or (iv)
issue, by  reclassification of its shares of Common Stock, any shares of capital
stock  (including any  reclassification  in connection with a  consolidation  or
merger in which the Company is the continuing corporation), the amount of Shares
purchasable upon the exercise of this Warrant immediately prior thereto shall be
adjusted so that the Holder shall be entitled to receive  upon  exercise of this
Warrant that number of Shares (or other capital stock of the Company)  which the
Holder  would  have  owned or would  have been  entitled  to  receive  after the
happening of such event had the Holder exercised this Warrant  immediately prior
to the record date, in the case of any such dividend,  or the effective date, in
the case of any such subdivision, combination or reclassification. An adjustment
made pursuant to this  subsection  (a) shall be made whenever any of such events
shall occur, but shall become effective  retroactively after such record date or
such  effective  date,  as the case may be, as to any  portion  of this  Warrant
exercised  between such record date or effective  date and the date of happening
of any such event.

          (b) If the Company shall issue, by reorganization or  reclassification
of its Common Stock (including any such  reorganization or  reclassification  in
connection  with  a  consolidation   or  merger  of  the  Company  with  another
corporation, provided the Company is the surviving corporation) other securities
or  property  of the  Company,  the Holder  shall  thereafter  have the right to
receive upon  exercise of this Warrant the kind and number of shares of stock or
other  securities or property  which he would have been entitled to receive upon
the happening of any such reorganization or  reclassification,  had this Warrant
been  exercised  immediately  prior  thereto;  and,  in  any  case,  appropriate
adjustment (as determined by the Board of Directors in good faith) shall be made
in the application of the provisions herein set forth with respect to rights and
interests  thereafter of the Holder,  to the end that the  provisions  set forth
herein shall  thereafter  be  applicable,  as near as reasonably  practical,  in
relation to any shares of stock or other securities or other property thereafter
deliverable  upon the exercise of this Warrant.  Any adjustment made pursuant to
this subparagraph (b) shall become effective retroactively to the effective date
of such reorganization or reclassification.

          (c) If the Company  shall issue,  sell,  grant or distribute to all or
substantially  all holders of shares of Common Stock evidences of  indebtedness,
any other  securities of the Company  (including,  without  limitation,  rights,
Warrants,  warrants or  convertible  or  exchangeable  securities  entitling the
holders thereof to subscribe for,  purchase,  or convert or exchange  securities
into,  shares of Common Stock,  whether or not  immediately  exercisable) or any
property or other assets (other than cash), and if such issuance, sale, grant or
distribution does not otherwise  constitute an event requiring  adjustment under
this  Section 7 (any such  nonexcluded  event  being  herein  called a  "Special
Dividend"),  then,  effective upon the record date of the Special Dividend,  the
Holder  shall be entitled to receive,  upon  exercise of this  Warrant  (and the
payment of the  consideration,  if any,  payable to the Company for such Special
Dividend  under the terms of its issuance,  sale,  grant or  distribution),  the
Special  Dividend  which the Holder would have been  entitled to receive if this
Warrant had been exercised  immediately  prior to the record date of the Special
Dividend.

          (d) In case the Company  shall make a  distribution  to all holders of
the  Common  Stock  of  stock  of a  subsidiary  of the  Company  or  securities
convertible into or exercisable for such stock, then in lieu of an adjustment in
the Exercise Price or the number of Shares  purchasable upon the exercise of the
Warrant,  the Holder,  upon the  exercise of this Warrant at any time after such
distribution,  shall be entitled to receive from the Company, such subsidiary or
both, as the Company  shall  determine,  the stock or other  securities to which
such Holder would have been entitled if such Holder had  exercised  this Warrant
immediately prior thereto, all subject to further adjustment as provided in this
Section 7, and the Company shall  reserve,  for the life of this  Warrant,  such
securities of such subsidiary.

          (e) If there shall be any consolidation or merger to which the Company
is a party,  other than a  consolidation  or a merger in which the  Company is a
continuing  corporation and which does not result in any reclassification of, or
change (other than a change in respect of which an adjustment is required  under
any other provision of this Section 7 or a change in par value) in,  outstanding
shares of Common Stock, or any sale or conveyance of the property of the Company
as an entirety or  substantially  as an entirety  (any such event being called a
"Capital  Reorganization"),  then,  effective  upon the  effective  date of such
Capital  Reorganization,  the  Holder  shall  have the right to  purchase,  upon
exercise  of this  Warrant,  the kind and  amount  of  shares of stock and other
securities  and property  (including  cash) which the Holder would have owned or
have been entitled to receive after such Capital  Reorganization if this Warrant
had been exercised  immediately prior to such Capital  Reorganization  (assuming
the Holder failed to exercise his rights of election,  if any, as to the kind or
amount of  securities,  cash or other  property  receivable  upon  such  Capital
Reorganization).  As a condition to effecting  any Capital  Reorganization,  the
Company or the  successor  or surviving  corporation,  as the case may be, shall
execute  and  deliver to the Holder and to the  Company an  agreement  as to the
Holder's  rights in accordance  with this Section 7,  providing  for  subsequent
adjustments  as  nearly  equivalent  as may be  practicable  to the  adjustments
provided  for in this  Section  7. The  provisions  of this  subparagraph  shall
similarly apply to successive Capital Reorganizations.

          (f)  After  any  adjustment  of the  number or kind of shares or other
securities or property  issuable  upon exercise of this Warrant  pursuant to the
provisions  of this Section,  the Exercise  Price shall also be adjusted so that
the aggregate  Exercise Price  thereafter  payable upon exercise of this Warrant
shall be equal to the  aggregate  Exercise  Price which would have been  payable
upon exercise of this Warrant immediately prior to such adjustment.

          (g) No  adjustment  shall be  required  unless such  adjustment  would
require an increase  or  decrease of at least one percent  (1%) in the number of
the Underlying Shares;  provided,  however, that any adjustments which by reason
of this  subsection  are not  required  to be made shall be carried  forward and
taken into account in any subsequent  adjustment.  All  calculations  under this
Section 7 shall be made to the nearest one-hundredth of a Share.

          (h) Whenever the number of Shares purchasable hereunder is adjusted as
herein  provided,  the  Company  shall  cause  to be  mailed  to the  Holder  in
accordance  with the  provisions  of this  Section a notice (i) stating that the
number of Shares  purchasable  upon exercise of this Warrant has been  adjusted,
(ii) setting forth the adjusted number of Underlying Shares, (iii) setting forth
the  adjusted  Exercise  Price,  and  (iv)  showing  in  reasonable  detail  the
computations  and the  facts,  including  the amount of  consideration,  if any,
received  or  deemed to have been  received  by the  Company,  upon  which  such
adjustments are based.  Such notice shall be conclusive as to the correctness of
the adjustment of the Underlying Shares and Exercise Price unless objected to by
the Holder  within 30 days  following the receipt of such notice by such Holder.
If the  Holder  objects  to the  adjustment  as  set  forth  in  such  notice  a
representative  of the  Company  shall  meet with the  Holder  at such  mutually
convenient time or times as shall be mutually acceptable to the parties in order
to agree as to the correct adjustment.  If the Company and the Holder are unable
to agree as to the correctness of the adjustment,  the matter shall be submitted
to a mutually acceptable firm of independent certified public accountants, whose
determination as to the correct  adjustment shall be conclusive and binding upon
the Company and the Holder.

          (i) The Company shall cause written notice of any Special  Dividend to
be mailed to the Holder at the earliest practicable time (and, in any event, not
less than 10 days  before the date fixed as a record date or the date of closing
the transfer books for the  determination of the  shareholders  entitled to such
Special Dividend.)

     8. LIQUIDATION OR DISSOLUTION. In case the Company dissolves or liquidates,
the Company shall make appropriate provision so that the securities or property,
as the case may be,  which would be received by the Holder upon the  exercise of
this  Warrant  at the  time  immediately  prior  to the  effective  date of such
dissolution or liquidation, will be available to the Holder from the liquidating
trust;  provided that the Holder shall make the  determination  as to whether to
exercise this Warrant  within six months of the effective date of dissolution or
liquidation,  at which time this Warrant shall be  terminated  and of no further
force  or  effect  and  the  Holder's   rights  under  this  Warrant   shall  be
automatically terminated.

     9.  FRACTIONAL  SHARES.  No  fraction  of a Share  shall be  required to be
delivered  upon the  exercise  of this  Warrant or any  portion  hereof.  If any
fractional  interest in a Share shall be  deliverable  upon the exercise of this
Warrant,  the Company  shall make an  adjustment  therefor in cash equal to such
fraction  multiplied  by the Current  Market Price of the Shares on the business
day next  preceding  the day of  exercise.  For  purposes of this  Warrant,  the
"Current Market Price" per share of Common Stock at any date shall be (i) if the
shares of Common Stock are listed on any national securities exchange, the daily
closing price on the date of  determination;  (ii) if the shares of Common Stock
are not listed on any national securities exchange but are quoted or reported on
the National Association of Securities Dealers, Inc., Automated Quotation System
("NASDAQ"), the last quoted price or, if not quoted, the average of the high bid
and low asked price as reported by NASDAQ,  as the case may be; and (iii) if the
shares of Common Stock are neither  listed on any national  securities  exchange
nor quoted or reported on NASDAQ, the closing bid price in the  over-the-counter
market as furnished by any NASDAQ member firm that is selected from time to time
by the Company.

     10. NO IMPAIRMENT.  The Company shall not by any action including,  without
limitation,   amending  its   certificate  of   incorporation   or  through  any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities  or any other  voluntary  action,  avoid or seek to avoid the
observance or performance  of any of the terms of this Warrant,  but will at all
times in good  faith  assist in the  carrying  out of all such  terms and in the
taking of all such  actions as may be necessary  or  appropriate  to protect the
rights of the Holder against impairment.  Without limiting the generality of the
foregoing,  the  Company  will (a) not  increase  the par value of any shares of
Common  Stock  receivable  upon the  exercise of this  Warrant  above the amount
payable  therefor upon such exercise  immediately  prior to such increase in par
value,  and (b) take all such action as may be necessary or appropriate in order
that the Company may  validly  and  legally  issue fully paid and  nonassessable
shares of Common Stock upon the exercise of this Warrant.

     11. REMEDIES. The Company stipulates that the remedies at law of the Holder
in the  event  of any  default  or  threatened  default  by the  Company  in the
performance  of or compliance  with any of the terms of this Warrant are not and
will not be adequate and that,  without  limiting any other remedy  available at
law,  such  terms may be  specifically  enforced  by a decree  for the  specific
performance  of any agreement  contained  herein or by an  injunction  against a
violation of any of the terms hereof.  The rights and remedies of the Holder are
cumulative  and not  exclusive of any rights or remedies  which the Holder might
otherwise have.

     12.  LOSS OR  DESTRUCTION.  Upon  receipt of evidence  satisfactory  to the
Company  of  the  loss,  theft,   mutilation  or  destruction  of  this  Warrant
Certificate,  the Company shall,  upon its receipt of an indemnity  agreement or
bond reasonably satisfactory in form, substance and amount to the Company or, in
the case of any such mutilation, upon surrender and cancellation of this Warrant
Certificate,  the Company at its expense will execute and deliver to the Holder,
in lieu thereof, a new Warrant Certificate of like tenor.

     13.  SURVIVAL.  The various rights and  obligations of the Holder hereof as
set forth herein shall  survive the exercise of this Warrant at any time or from
time to time and the surrender of this Warrant Certificate.

     14.  NOTICES.  Whenever any notice,  payment of any purchase price or other
communication (any such notice, payment or other communication, a "Delivery") is
required to be given or delivered  under the terms of this Warrant,  it shall be
in writing and  delivered by hand  delivery or Federal  Express or registered or
certified United States mail, postage prepaid and return receipt requested,  and
will be deemed to have been given or delivered on the date such notice, purchase
price or other communication is so delivered. Any Delivery to the Company, shall
be addressed to 10254 Miller Road, Dallas, Texas 75238, or to such other address
as the Company may hereafter designate to the Holder in writing; any Delivery to
the Holder  shall be  addressed  to such  address  as the  Holder may  hereafter
designate to the Company in writing.

     15.  CHANGE;  WAIVER.  Neither  this  Warrant  nor any term  hereof  may be
changed,  waived,  discharged or terminated orally, but only by an instrument in
writing  signed by the party against which  enforcement  of the change,  waiver,
discharge  or  termination  is  sought.  No  failure  or delay of the  Holder in
exercising any power or right hereunder  shall operate as a waiver thereof,  nor
shall  any  single  or  partial  exercise  of any such  right or  power,  or any
abandonment  or  discontinuance  of steps  to  enforce  such a right  or  power,
preclude  any other or further  exercise  thereof or the  exercise  of any other
right or power.

     16.  COVENANTS TO BIND  SUCCESSOR  AND  ASSIGNS.  The terms of this Warrant
shall bind the successors and permitted assigns of the Holder and the Company.

     17.  SEVERABILITY.  In case any one or more of the provisions  contained in
this Warrant  shall be invalid,  illegal or  unenforceable  in any respect,  the
validity,  legality or  enforceability  of the  remaining  provisions  contained
herein shall not in any way be affected or impaired  thereby.  The parties shall
endeavor  in  good  faith  negotiations  to  replace  the  invalid,  illegal  or
unenforceable  provisions  with valid  provisions  the economic  effect of which
comes as close as  possible  to that of the  invalid,  illegal or  unenforceable
provisions.
