                             B. TRANSACTION SUMMARY

TRANSACTION OVERVIEW
________________________________________________________________________________
TRANSACTION SUMMARY

TRANSACTION
   SUMMARY:    In the proposed transaction (the  "Transaction"),  CST will cause
               TLC to increase borrowings from the bank group and upstream $23.4
               million  in cash to CST  ($20  million  as a  dividend  and  $3.4
               million  as  repayment  of  intercompany  debt).  CST  will  then
               purchase $10.0 million of  Weatherford  shares in the open market
               to be distributed to CST Shareholders (the "Mandatory Purchase").
               Under  certain  conditions,  CST may be  obligated to purchase an
               additional  $5.0 million of Weatherford  shares to be distributed
               to CST Shareholders (the "Contingent Purchase").

               CST will then sell  two-thirds  of the interest in TLC to C-2 for
               $10,666,667.  CST will then  merge  with and into a  wholly-owned
               subsidiary  of  Weatherford  in  a  transaction  qualifying  as a
               reorganization  under  Section  368(a)(1)(A)     of the  Internal
               Revenue Code.

CONSIDERATION: Each issued and  outstanding  share of CST common stock (the "CST
               Common  Stock")  will be  converted  into the  right  to  receive
               approximately  .76  shares of Weatherford plus $4.09 in Cash/(1)/
               and  the  pro  rata  number  of  additional   Weatherford  Shares
               distributed in the Mandatory Purchase or (Cont'd)
_______________
(1) The Cash is equal to the sum of (i) $20 million to be received in connection
with a Dividend  payable to CST by TLC,  (ii) $10.7 million to be paid to CST in
connection  with the sale of  two-thirds  of the  interest in TLC to C-2,  Inc.,
(iii) $3.3  million to be received by CST in  connection  with the  repayment of
intercompany debt and (iv) all other cash of CST at the time of closing less the
sum  of (i)  an  amount  of  cash  necessary  to pay  any  CST  liabilities  and
Transaction expenses less the Mandatory Purchase. See "Transaction Consideration
Analysis" p. 36.


TRANSACTION OVERVIEW
________________________________________________________________________________
TRANSACTION SUMMARY

CONSIDERATION
  CONT'D:      approximately .76 shares of  Weatherford plus $3.12 Cash/(1)/ and
               the   pro   rata   number   of   additional   Weatherford  Shares
               distributed   in  the  Mandatory   Purchase  and  the  Contingent
               Purchase.

CONTINGENT PURCHASE
 CIRCUMSTANCE: If at the time of  closing,  the price  per share of  Weatherford
               Stock is between  $19.00 and $14.00,  CST is required to exercise
               such portion of the  Contingent  Purchase  necessary to allow the
               Merger to be  treated as a "tax  free"  reorganization  under the
               Internal   Revenue  Code.  The  minimum  price  under  which  the
               transaction will close is $14.00.

ORIGINAL
  AGREEMENT:   In the Original  Agreement,  $10.0  million was to be left in CST
               according  to the  terms of the  merger,  and net of  liabilities
               which might arise,  $10.0 million was payable to CST shareholders
               five  years  after  the  Transaction   closed.   In  the  current
               agreement,  the $10.0  million will  instead  fund the  Mandatory
               Purchase.  In the Original  Agreement,  there was no Mandatory or
               Contingent Purchase.
_______________
(1) The Cash is equal to the sum of (i) $20 million to be received in connection
with a Dividend  payable to CST by TLC,  (ii) $10.7 million to be paid to CST in
connection  with the sale of  two-thirds  of the  interest in TLC to C-2,  Inc.,
(iii) $3.3  million to be received by CST in  connection  with the  repayment of
intercompany debt and (iv) all other cash of CST at the time of closing less the
sum  of (i)  an  amount  of  cash  necessary  to pay  any  CST  liabilities  and
Transaction  expenses less the Mandatory Purchase less the Contingent  Purchase.
See "Transaction Consideration Analyst" p. 36.


TRANSACTION OVERVIEW
________________________________________________________________________________
TRANSACTION SUMMARY

STOCK/CASH
  ELECTION:    Each CST shareholder will be given the opportunity to participate
               in the two-thirds  sale of TLC to C-2 via an election to purchase
               C-2 stock. With respect to the Cash portion of the Consideration,
               each  CST  shareholder  will be  required  to  make  an  election
               (assuming the  Contingent  Purchase is not  exercised) to receive
               either (i) cash or (ii) cash and C-2 stock prior to the effective
               date of the Transaction.

PUT OPTION:    Weatherford  will  receive from C-2 a put option to sell its one-
               third   ownership  position  in  TLC to C-2 for $7.1 million five
               years from the effective date of the Transaction.

TAX
 CONSEQUENCES: Weatherford  must hold TLC for a minimum of five years  after the
               Transaction (except in accordance with the Participation  Rights)
               in order  to meet the  continued  business  interest  requirement
               pursuant to Section 368 (a) of the Internal Revenue Code of 1986,
               as amended.  The Weatherford  shares will be received tax-free by
               the CST Shareholders, while all proceeds of any cash distribution
               to CST Shareholders  would be subject to capital gains tax to the
               extent the cash and the value of the Weatherford  shares received
               by the CST shareholders exceed the shareholders' basis in CST.

PARTICIPATION
  RIGHTS:      In the event that C-2  proposes a sale of its  interest in TLC to
               an  unrelated  third  party,  Weatherford  will have the right to
               participate in that sale (i.e.  Weatherford has the right to sell
               its interest in TLC at the same time.)

________________________________________________________________________________
RECENT EVENTS

- -              On August 17,  1998 at a special  meeting of CST's  shareholders,
               the merger between CST and  Weatherford  pursuant to an agreement
               dated  December  12,  1997  was  approved.  The  Merger  was  not
               consummated  because  the  decrease  in the price of  Weatherford
               stock from $46.38 on December  12,  1997 (the last  trading  date
               prior to a public  announcement  of the  Merger) to below  $30.00
               prevented   the  Merger  from  being  treated  as  a  "tax  free"
               reorganization  under the Internal  Revenue Code thereby  leaving
               unsatisfied a material condition to the closing of the merger.

- -              On May 27,  1998,  a  merger  between  EVI Inc.  and  Weatherford
               Enterra Inc. was  completed.  The  combined  entity,  Weatherford
               International,  Inc., trades on the New York Stock Exchange under
               the symbol  "WFT."  EVI Inc.  completed its buyout of Weatherford
               Enterra Inc. for $2.77 billion. The transaction was accounted for
               as a pooling of  interests,  whereby  Weatherford  Enterra Inc.'s
               stockholders  received  0.95  shares of newly  issued  shares  of
               Weatherford International, Inc. common stock for each Weatherford
               Enterra common share.

TRANSACTION OVERVIEW
________________________________________________________________________________
RATIONALE

               CST Shareholders will receive  consideration,  which represents a
               12.3%  premium/(1)/  on a per  share  basis to CST  shareholders'
               current per share market value.

               CST  Shareholders  will  receive   Weatherford  Common  Stock  in
               exchange for CST Common Stock on a tax-free basis.

               The Transaction  eliminates  $20.8  million/(2)/ in capital gains
               tax  which  would be  realized  at the CST  corporate  level in a
               liquidation.

               The Transaction  significantly enhances liquidity for current CST
               Shareholders.

               The  Transaction  allows for  meaningful  realization of value in
               CST's TLC subsidiary.

               The  Transaction  allows  current  shareholders  of CST to have a
               direct investment in Weatherford Common Stock.

               The Transaction allows current shareholders of CST to participate
               in the TLC business on the same terms as management.

CST/TLC OVERVIEW

               In addition to the refrigerated  distribution  centers  described
               above,  TLC  operates a national  network of owned and leased dry
               distribution    centers   (non-refrigerated)    which    comprise
               approximately 900,000 square feet of storage capacity.  TLC's dry
               distribution  centers  are  located  in  Zeeland  and  Kalamazoo,
               Michigan;  Munster,  Indiana;  South Brunswick,  New Jersey;  and
               Bayamon, Puerto Rico.

               Competition in integrated logistic services is both on a national
               and local basis with a  predominant  emphasis  on  transportation
               services.  At  present,  there  are no  direct  competitors  that
               provide the same type of warehousing and transportation  services
               as TLC. Each of TLC's individual  business segments,  however, is
               highly   fragmented  with  many  local,   regional  and  national
               competitors  (especially  those  in the  transportation  and  dry
               warehousing industries). TLC's competitive edge is its ability to
               provide  fully  integrated  logistic  services  designed  for its
               customers'  distribution needs and the utilization of its network
               of   strategically-located   refrigerated  and  dry  distribution
               centers.

ALTERNATIVE TRANSACTION
________________________________________________________________________________
TAX LIABILITY COMPARISON
(Dollars in thousands except per share data)

An  alternative  to the proposed  Transaction is the outright sale by CST of its
position  in  Weatherford  Common  Stock for cash.  While  this  alternative  is
recognized as a method in which CST  shareholders  would be able to monetize the
current value of their ownership in Weatherford, significant capital gains taxes
would be incurred at the CST corporate level and significant ordinary income tax
would be incurred at the shareholder level.

In the proposed  Transaction,  the corporate tax liability would be eliminated,
and the tax at the  shareholder  level would be deferred  until the  individual
shareholder liquidated his holding in Weatherford.
