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 TRANSACTION OVERVIEW ________________________________________________________________________________ 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.

RATIONALE 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. ______________ (1) See "Transaction Consideration Analysis," pg. 35.

CST/TLC OVERVIEW COMPANY OVERVIEWS ________________________________________________________________________________ CST/TLC OVERVIEW CST, headquartered in Milwaukee, Wisconsin, is primarily engaged in providing public refrigerated and non-refrigerated warehousing and logistic services. CST's principal businesses/assets include 3,897,462 shares of Weatherford Common Stock and TLC. TLC provides full service public and contract warehousing, as well as logistic services in all ranges of refrigerated and ambient temperatures. TLC also provides a full range of international freight management services, fully computerized inventory management, repackaging and just-in-time production supply services. TLC's customers are primarily national, regional and local firms engaged in food processing, consumer product manufacturing, wholesale distribution and retailing. TLC's refrigerated distribution centers are located in Rochelle, Illinois; Beaver Dam, Wisconsin; Wauwatosa, Wisconsin; Holland, Michigan; and Kalamazoo, Michigan. COMPANY OVERVIEWS ________________________________________________________________________________ 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 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.
