                                       in excess of its accrued unpaid taxes,   makes no additional purchases of

                                       certain tax deductions to be retained
                                       by Christiana, and its fixed

                                       divided by the number of shares of

          The consideration payable in the merger by Weatherford will in essence
come from Christiana's existing assets because the Weatherford share
consideration and the cash consideration will be based on and will not exceed
the Weatherford common stock and cash held by Christiana. As a result,
Weatherford will not be required to pay any consideration for the assets being
acquired by it through the merger other than its agreement to engage in the
merger and bear certain costs of the transaction.
 
   
     PLEASE NOTE THAT THE ENCLOSED MATERIALS RELATE TO A PLAN OF MERGER THAT IS
DIFFERENT FROM THE PLAN THAT WAS APPROVED BY THE STOCKHOLDERS OF CHRISTIANA AND
WEATHERFORD ON AUGUST 17, 1998. THE PRIOR PLAN OF MERGER WAS NEVER COMPLETED
BECAUSE IT COULD NOT BE CLOSED ON A PARTIALLY TAX FREE BASIS. THE NEW PLAN OF
MERGER IS DESIGNED TO ALLOW FOR THE MERGER TO CLOSE ON A PARTIALLY TAX FREE
BASIS. YOU SHOULD READ THESE MATERIALS CAREFULLY TO UNDERSTAND THE REVISED TERMS
OF THE MERGER.

PROPOSED TRANSACTIONS
 
   
     Christiana is pursuing the transaction as a means of separating its
Weatherford shareholdings from its transportation and warehousing business to
provide its shareholders with more value for their holdings. The proposed
transactions are a means by which Christiana can accomplish this with no
corporate or individual tax, except tax on the cash payment that Weatherford
will pay to the Christiana shareholders. Christiana will transfer a one-third
interest in TLC to Weatherford as part of the transaction. The merger and
related transactions will be effected in three parts that will all occur at the
same time:
    
 
   
        - First, C2, a new company formed by Sheldon Lubar, will offer shares of
     its common stock to the Christiana shareholders on a pro rata basis for a
     total consideration of up to $20.8 million. C2 will apply $10.67 million of
     the proceeds of that offering to purchase a two-thirds interest in TLC.
    
 
   
        - Second, Christiana will sell to C2 a two-thirds interest in TLC for
     $10.67 million. As part of this transaction, C2 and TLC will assume all
     historical liabilities of Christiana and indemnify Christiana and
     Weatherford from them.
    
 
   
          - Third, a Weatherford subsidiary will merge into Christiana with its
     only assets being a one-third interest in TLC, its shares of Weatherford
     common stock and cash. The cash held by Christiana will be equal to the
     cash Weatherford will pay to the Christiana shareholders in the merger plus
     an amount equal to Christiana's unassumed liabilities and certain tax
     benefits.
    
 
   
WHAT CHRISTIANA SHAREHOLDERS WILL RECEIVE
    
 
   
  CHRISTIANA SHAREHOLDERS.
    
 
   
     In the merger, Weatherford will pay to the Christiana shareholders a
combination of Weatherford common stock and cash.
    
 
   
  Weatherford Shares
    
 
   
     If you approve the merger, Weatherford will issue shares of its common
stock to Christiana shareholders. We will calculate the number of shares of
Weatherford common stock Weatherford will issue in the merger by dividing the
number of shares of Weatherford common stock held by Christiana at the time of
the merger by the total number of Christiana shares outstanding immediately
prior to the merger. Currently, this would mean that each Christiana shareholder
would receive .85191 of a share of Weatherford common stock for each share of
Christiana common stock it owns. We plan to calculate the final number no later
than 10 days after the special meetings.
    
 
   
     If the market price of Weatherford common stock is between $12.75 and
$18.30 per share at the time of the special meetings, Christiana is required to
purchase up to an additional $5.0 million in Weatherford common stock. These
purchases are intended to assure that the Christiana shareholders do not incur a
tax liability upon receipt of the Weatherford shares. If Christiana purchases
$5.0 million of these shares, Weatherford will issue to Christiana shareholders
between .9281 and .9050 of a share of Weatherford common stock for each share of
Christiana common stock that they own. If the price of Weatherford common stock
falls below $12.75 per share, it is unlikely that we will complete the merger.
On December 22, 1998, the closing sale price of the Weatherford common stock was
$17 1/16.
    
 
   
  Cash Payment.
    
 
   
     Formula for Determining Cash Payment. Weatherford will pay cash to the
Christiana shareholders as follows. Within 30 days following the merger,
Weatherford will calculate the amount of cash held by Christiana as of the date
of the merger and reduce from that amount the liabilities of Christiana as of
the date of the merger and its accrued unpaid taxes. The calculation of the
amount of cash will not give effect to the value of the tax deductions that
Christiana may have realized from the exercise or cancellation of stock
    
 
                                        5
<PAGE>   9
 
   
options. Weatherford will divide this amount by the number of shares of
Christiana common stock outstanding immediately prior to the merger, with the
result being the cash consideration payable per share.
    
 
   
     Per Share Cash Payment Ratio Based on Current Facts. Based on the number of
shares of Christiana common stock currently outstanding, the Christiana
shareholders would receive between $3.50 and $4.00 per share in cash for their
shares in the merger. The actual cash consideration could vary from these
amounts to the extent there are changes in Christiana's cash and liabilities.
    
 
   
     Cash Payment in the Event Christiana Purchases Additional Shares of
Weatherford Common Stock. If the market price of Weatherford common stock is
between $12.75 and $18.30 per share at the time of the special meetings and
Christiana is required to use $5.0 million to purchase additional shares of
Weatherford common stock, Weatherford's cash payment to the Christiana
shareholders could decline by up to $1.00 per share. We will not know until
after the special meetings whether and to what extent this reduction will occur.
    
 
  WEATHERFORD STOCKHOLDERS.
 
     The merger will make no changes to the Weatherford common stock and the
Weatherford stockholders will continue to hold the same number of shares of
Weatherford common stock after the merger as they held before the merger.
 
     The merger will also result in no change in the outstanding number of
shares of Weatherford common stock because the number of Weatherford shares to
be issued in the merger will equal the number of shares of Weatherford common
stock owned by Christiana at the time of the merger.
 
   
WHAT CHRISTIANA SHAREHOLDERS WILL RECEIVE IN THE MERGER FOR THE ASSETS OF
CHRISTIANA
    
 
   
     The following chart sets forth a general allocation of the consideration to
be paid by Weatherford for the assets of Christiana that Weatherford will
acquire in the merger:

(1) The estimate of the cash consideration is based on the balance sheet of
    Christiana as of September 30, 1998 after giving effect to the estimated
    expenses of the merger payable by Christiana and estimated cash flow through
    the anticipated date of closing.
    
 
   
(2) Christiana will sell two-thirds of its interest in TLC to C2 prior to the
    merger.
    
 
   
     Under the terms of the merger agreement, Christiana is required to bear
significant transaction costs, which are estimated to be approximately $2.8
million, including approximately $0.3 million of costs of Weatherford. If the
actual costs to be paid by Christiana are higher than those currently estimated,
the cash consideration to be paid in the merger will be less than currently
estimated. Christiana is not required to pay approximately $1.5 million of the
expenses of Weatherford.

RELATED PARTY TRANSACTIONS
 
   
     TLC Sale.  Christiana's sale of a two-thirds interest in TLC to C2 is an
important aspect of the merger. We structured the merger this way because
Weatherford did not want to obtain a controlling interest in TLC. Christiana
will sell two-thirds of its interest in TLC for $10.67 million. Mr. Sheldon
Lubar, who controls C2, suggested the purchase price. Weatherford considered the
purchase price C2 paid in determining the amount of cash Weatherford would pay
Christiana shareholders.
    
 
   
     Indemnification.  Christiana shareholders should be aware that C2 and TLC
will be obligated to indemnify Weatherford for various matters including, but
not limited to, the following:
    
 
     - Historical liabilities of Christiana and its current and historical
       subsidiaries and predecessors.
 
   
     - Any liability relating to any claim or damage by any shareholder of
       Christiana or Weatherford that relates to the merger, the sale of TLC to
       C2 or any transaction relating to those transactions.
    
 
   
     - Any taxes that may arise if the IRS determines that the merger is a
       taxable transaction.
    
 
   
As a result, C2 and TLC could be subject to significant liabilities. Weatherford
would not enter into the merger without these indemnification requirements.
    
 
   
     TLC Operating Agreement.  The operating agreement will govern the
operations of TLC following the merger. Various actions of TLC will require the
approval of both C2 and Christiana. Christiana also will have the right to sell
its interest in TLC to C2 and TLC for $7.0 million in cash five years after the
closing of the merger as well as the right to participate in various
dispositions by C2 of its interest in TLC.
    
 
   
     C2 and Christiana will each be entitled to Board representation
proportionate to their interests in TLC. Subject to certain exceptions,
Christiana will not be able to sell or transfer its interest in TLC without the
consent of the Board of Managers of TLC. This restriction will survive for a
period of five years. Christiana may transfer its interest in the event of
certain changes of control of C2.
    
 
   
     C2 Offering.  To finance its acquisition of TLC, C2 is offering to the
shareholders of Christiana the right to subscribe for their pro rata share of
the C2 common stock. The C2 offering is intended to allow the Christiana
shareholders to continue to participate and have an ownership interest in TLC.
The Lubar family has committed to purchase enough shares of C2 common stock so
that the net proceeds to C2, after deducting the expenses of the C2 offering,
are at least $10.67 million. This commitment will provide C2 with the ability to
purchase the two-thirds interest in TLC required under the merger agreement.
This joint proxy statement/prospectus is not being provided by Weatherford or C2
as part of the C2 offering.
    
 
   
     The merger agreement, the TLC purchase agreement and the operating
agreement are attached as Appendices A, B and C to this joint proxy
statement/prospectus. We encourage you to read these documents carefully.

RECOMMENDATION TO CHRISTIANA SHAREHOLDERS
 
   
     The Board of Directors of Christiana is of the opinion that the merger is
in the best interests of Christiana and its shareholders and recommends that
they vote "FOR" the merger proposal. There are four principal reasons for this
opinion:
    
 
     - First, the use by Christiana of up to $15.0 million of its cash to
       acquire Weatherford common stock comes at a time when the Weatherford
       common stock is considered by the Christiana Board of Directors to be an
       attractive investment and allows the Christiana shareholders to
       essentially reinvest in a tax free manner the money that might otherwise
       have been distributed to them in the merger.
 
     - Second, Christiana shareholders who will become Weatherford stockholders
       should be able to more easily sell their Weatherford common stock than
       they were able to sell their Christiana common stock, because Weatherford
       common stock has more liquidity in the public market than does Christiana
       common stock.
 
   
     - Third, the merger will allow the Christiana shareholders to receive the
       shares of Weatherford common stock held by Christiana without (1)
       Christiana incurring tax on a disposition of the Weatherford shares held
       by it and (2) the Christiana shareholders incurring tax on their receipt
       of the Weatherford shares.
    
 
   
     - Fourth, the merger will allow for a better valuation of the businesses of
       Christiana by separating Christiana's ownership of Weatherford common
       stock from Christiana's ownership of TLC. The Christiana Board believes
       that this separation should allow for a better valuation of TLC as a
       division of C2 and will benefit the Christiana shareholders to the extent
       they elect to invest in C2.
    
 
RECOMMENDATION TO WEATHERFORD STOCKHOLDERS
 
     The Board of Directors of Weatherford is of the opinion that the merger is
in the best interests of Weatherford and its stockholders and recommends that
they vote "FOR" the merger proposal. There are three principal reasons for this
opinion:
 
   
     - First, the merger will allow Weatherford to acquire a one-third interest
       in TLC for no consideration other than agreeing to be a party to the
       transaction. Weatherford believes that the business of TLC is an
       attractive business for growth and that its investment in TLC should
       increase in value with minimal investment of time and money by
       Weatherford. In addition, at any time after the fifth anniversary of the
       closing of the merger, Weatherford has the right to sell to C2 or TLC its
       one-third interest in TLC for $7.0 million.
    
 
   
     - Second, the merger will result in no dilution to Weatherford because the
       number of its outstanding shares before and after the merger will not
       change. Any income attributable to TLC also will be accretive to
       Weatherford.
    
 
     - Third, the merger will result in a better distribution of the Weatherford
       common stock because the Christiana shareholders will hold shares of
       Weatherford common stock directly rather than through Christiana.
 
OPINION OF WEATHERFORD'S FINANCIAL ADVISOR
 
   
     In deciding to approve the merger, the Weatherford Board received and
considered the opinion dated October 9, 1998 of Morgan Stanley & Co.
Incorporated, its financial advisor, as to the fairness of the consideration to
be paid by Weatherford from a financial point of view as of such date. The
opinion is attached as Appendix D to this joint proxy statement/prospectus. You
should read the opinion in its entirety to understand the assumptions made,
matters considered and limits of the review undertaken by Morgan Stanley in
providing its opinion.

OPINION OF CHRISTIANA'S FINANCIAL ADVISOR
 
   
     In deciding to approve the merger, the Christiana Board received and
considered the opinion of Prudential Securities, its financial advisor, as to
the fairness of the merger consideration to the shareholders of Christiana from
a financial point of view. The opinion is attached as Appendix E to this joint
proxy statement/prospectus. You should read the opinion in its entirety to
understand the assumptions made, matters considered and limits of the review
undertaken by Prudential Securities in providing its opinion.
    
 
INTERESTS OF CHRISTIANA OFFICERS AND DIRECTORS IN THE MERGER
 
     When considering the recommendations of the Christiana Board of Directors,
the Christiana shareholders should be aware that officers and directors of
Christiana have interests and arrangements that may be different from your
interests as shareholders, including the following:
 
     - The executive officers and directors of Christiana will be executive
       officers and directors of C2.
 
     - The Lubar family will commit to purchase shares in the C2 offering and
       will thereby obtain control of C2. If the Christiana shareholders do not
       exercise their right to purchase a pro rata interest in C2, the Lubar
       family's interest in C2 could increase from approximately 52% to 100%.
 
   
     - Each officer and other holder of options to purchase Christiana common
       stock will be entitled to receive cash for their options equal to the
       difference between $40.00 and the option exercise price. This price was
       fixed at the time the merger agreement was initially entered into and is
       substantially greater than the current market price. Christiana's
       officers who hold options to purchase Christiana common stock will in the
       aggregate receive $1,716,000 for their options.
    
 
CONDITIONS TO THE MERGER AND RELATED TRANSACTIONS
 
   
     We will complete the merger and related transactions only if certain
conditions, including the following, are satisfied or waived:
    
 
     - Christiana and Weatherford stockholders approve the merger.
 
   
     - We receive all required material governmental approvals and other
       consents.
    
 
     - Arthur Andersen LLP reconfirms at the closing that the merger will be
       partially tax free.
 
   
     - Christiana completes the sale of its two-thirds interest in TLC to C2.
    
 
   
     - Christiana undergoes no material adverse change, financial or otherwise,
       after the date of the merger agreement.
    
 
   
Each of Weatherford and Christiana may waive various conditions of the merger.
If either party waives any material conditions to closing the merger, we would
provide our stockholders supplemental disclosure of such waiver and a reasonable
opportunity to change their votes.
    
 
TERMINATION OF THE MERGER AGREEMENT
 
   
     We may mutually agree to terminate the merger agreement without completing
the merger. The merger agreement also may be terminated in certain other
circumstances, including the following:
    
 
     - By Weatherford or Christiana if the stockholders of either company do not
       approve the merger.
 
     - By Weatherford or Christiana if the merger is not effected on or before
       January 31, 1999.
 
     - By a non-breaching party in the event of a material breach by the other
       party.
 
     - By Weatherford or Christiana if a court or governmental authority has
       acted to prevent the merger.
 
     - By Weatherford's Board of Directors or Christiana's Board of Directors if
       that Board determines in its good faith judgment that a termination of
       the merger agreement is appropriate in complying with its fiduciary
       duties.
 
                                       10
<PAGE>   14
 
     - By Weatherford or Christiana if the other party withdraws its
       recommendation with respect to the merger in a manner adverse to it or
       resolves to do the same.
 
   
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
    
 
     The merger is conditioned on the receipt of opinions from Arthur Andersen
LLP that, among other things:
 
     - The issuance of the shares of Weatherford common stock to the Christiana
       shareholders will be tax free.
 
     - No gain or loss for U.S. federal income tax purposes will be recognized
       by Weatherford, Sub or Christiana as a result of the merger.
 
     - Weatherford and Christiana are parties to a reorganization under federal
       tax laws.
 
     - No gain or loss will be recognized by the shareholders of Christiana upon
       their receipt of shares of Weatherford common stock in exchange for their
       shares of Christiana common stock.
 
     Arthur Andersen has rendered an opinion as to the above matters for
purposes of this Joint Proxy Statement/Prospectus. This opinion is required to
be redelivered at closing. If the opinion to be delivered by Arthur Andersen is
waived, or if there are modifications to the opinion that would state that the
merger would be taxable in whole or in part to Weatherford, Christiana or the
stockholders of Weatherford or Christiana, we will provide additional disclosure
to our respective stockholders and provide you an opportunity to change your
vote on the merger.
 
     Tax matters are complicated, and the tax consequences of the proposed
transactions to you will depend on the facts of your own situation. You should
consult your own tax advisors for a full understanding of the tax consequences
to you of the merger.
 
APPRAISAL RIGHTS
 
     Under Wisconsin law, Christiana shareholders may dissent from the merger
and demand the "fair value" of their shares in cash. To exercise this right, you
may not vote your shares in favor of the merger and you must take certain other
actions that Wisconsin law requires.
 
     Weatherford stockholders will have no right to an appraisal of the value of
their shares in connection with the merger under Delaware law.
 
COMPARATIVE RIGHTS
 
     Weatherford is a Delaware corporation and Christiana is a Wisconsin
corporation. The laws of those jurisdictions vary. Following the merger,
Christiana shareholders will hold shares in Weatherford and Delaware law will
govern their rights instead of Wisconsin law. There also exist various
differences between Weatherford's certificate of incorporation and bylaws and
Christiana's articles of incorporation and bylaws.

                        WEATHERFORD UNAUDITED PRO FORMA
                     CONDENSED CONSOLIDATED FINANCIAL DATA
 
     The following tables set forth certain summary pro forma condensed
consolidated financial data of Weatherford. The Unaudited Pro Forma Condensed
Consolidated Statements of Income give effect to the proposed merger of
Christiana as if the transaction had occurred on January 1, 1997. Because the
fiscal years of Weatherford and Christiana differ, Christiana's December 31,
1997 historical operating results are based on Christiana's last two fiscal
quarters of its fiscal year ended June 30, 1997, combined with the results for
the six months ended December 31, 1997. The Unaudited Pro Forma Condensed
Consolidated Balance Sheet gives effect to the merger as if this transaction had
occurred on September 30, 1998.
 
     The unaudited pro forma information below is not necessarily indicative of
the results that actually would have been achieved if the transactions had been
consummated as of the dates reflected, or that may be achieved in the future.

(1) On May 27, 1998, Weatherford acquired Weatherford Enterra, Inc., issuing
    additional shares of Weatherford common stock and thereby reducing
    Christiana's ownership percentage in Weatherford to approximately 4%. As a
    result, on May 27, 1998, Christiana changed the manner in which it accounts
    for its investment in Weatherford from the equity method to the cost method.
    Under the cost method, only dividends paid by Weatherford will be reflected
    in future earnings of Christiana.
 
(2) All earnings per share amounts have been restated to reflect the adoption of
    Statement of Accounting Standards No. 128, "Earnings Per Share", effective
    December 15, 1997.

     If the market price of the Weatherford common stock declines below $18.30
per share, Christiana is required to purchase up to $5.0 million of additional
shares of Weatherford common stock. These purchases, if made, would increase the
conversion rate, which will increase the amount of Weatherford common stock and
decrease the cash consideration.

                                  RISK FACTORS
 
   
     An investment in the Weatherford common stock offered by this joint proxy
statement/prospectus involves a high degree of risk. Before you decide to invest
in the Weatherford common stock offered by this joint proxy
statement/prospectus, you should carefully consider the following factors,
together with the information contained or incorporated by reference in this
joint proxy statement/prospectus.
    
 
   
  Unexpected Federal Income Tax Treatment of the Merger May Have Adverse
Consequences on Weatherford
    
 
   
     If the IRS determines that the issuance of the shares of Weatherford common
stock to be issued in the merger is not tax free, the Christiana shareholders
will be taxed based on the value of the shares of Weatherford common stock
received. The merger is conditioned on the receipt of an opinion of Arthur
Andersen LLP that the issuance of the shares of Weatherford common stock to be
issued to the Christiana shareholders will be tax free. While Arthur Andersen
LLP has rendered that opinion for this joint proxy statement/prospectus, that
opinion is not binding on the IRS. TLC and C2 have agreed to indemnify
Weatherford from any adverse tax consequences of the merger not being tax free.
See "Related Party Transactions -- Terms of the TLC Sale -- Indemnification" and
"The Merger -- Terms of the Merger -- Conditions to the Merger".
    
 
   
  Low or Continued Low Prices of Oil and Natural Gas May Adversely Affect Demand
for Weatherford's Products
    
 
   
     Generally, you can expect low oil prices to adversely affect demand
throughout the oil and natural gas industry, including the demand for
Weatherford's products. In this case, you also could expect Weatherford's
revenues and income to be adversely affected.
    
 
     The price of oil and natural gas and the level of oil and natural gas
exploration activity strongly affects the demand for Weatherford's drilling
products, while oil production activity directly affects Weatherford's
production equipment and services.
 
   
     Oil prices have declined significantly in recent months and over the last
year due to a worldwide oversupply and lower than expected demand. The recent
declines in the price of oil have affected Weatherford in various ways.
Weatherford's artificial lift segment has been materially affected by lower oil
prices and their effect on reduced production of heavy oil production that is
heavily dependent on price. Weatherford's drill pipe and drill stem products
have been affected by significant declines in backlog, with demand for 1999
expected to be down between 40% and 60% from 1998. Weatherford's completion and
rental business has experienced declines in line with the general reduction in
industry activity, with the greatest declines occurring in the United States
markets.
    
 
   
     Weatherford's business will continue to be affected by industry conditions,
including those conditions and factors described above under "Uncertainty of
Forward-Looking Statements".
    
 
   
  Disruptions in Foreign Operations Could Adversely Affect Weatherford's Income
    
 
   
     Weatherford's operations in Singapore, Mexico, Brazil, Venezuela, Nigeria,
Algeria and Argentina are subject to various political and economic conditions
existing in such countries that could disrupt operations. Disruptions may occur
in Weatherford's foreign operations and losses may occur that will not be
covered by insurance.
    
 
   
     Weatherford also has drill pipe and other products manufactured for it by
Oil Country Tubular Limited ("OCTL") in India under a long-term exclusive
manufacturing arrangement with OCTL. Although Weatherford has sought to minimize
the risks of this operation through its manufacturing arrangement and insurance,
Weatherford is providing OCTL with a substantial amount of raw materials and
inventory for the products manufactured by it. Weatherford's Indian operations
have been adversely affected by the downturn of the economies in the eastern
hemisphere. Operations in India are subject to various political and economic
    
 
                                       18
<PAGE>   22
 
   
risks as well as financial risks with respect to OCTL. A termination or shutdown
of this operation in light of current market conditions or political factors,
could have an adverse effect on Weatherford's income and results.
    
 
   
  Weatherford's Products and Services Are Subject to Operational Hazards
    
 
   
     Weatherford's products are used for the exploration and production of oil
and natural gas. These operations are subject to hazards inherent in the oil and
gas industry that can cause personal injury or loss of life, damage to or
destruction of property, equipment, the environment and marine life, and
suspension of operations. Such hazards include fires, explosions, craterings,
blowouts and oil spills. Litigation arising from an accident at a location where
Weatherford's products or services are used or provided may result in
Weatherford being named as a defendant in lawsuits asserting potentially large
claims.
    
 
   
  Weatherford's Common Stock Has Fluctuated Historically
    
 
   
     Christiana shareholders may face significant devaluation of the shares of
Weatherford common stock they receive in the merger if the price of Weatherford
common stock declines due to the volatility of the price of common stock of
companies engaged in the oil and gas industry. Historically, and in recent
months in particular, the market price of common stock of companies engaged in
the oil and gas industry has been highly volatile. Likewise, the market price of
Weatherford common stock has varied significantly in the past. News
announcements and changes in oil and natural gas prices, changes in the demand
for oil and natural gas exploration and changes in the supply and demand for oil
and natural gas have all been factors that have affected the price of
Weatherford common stock.

                           FORWARD-LOOKING STATEMENTS
 
   
     This joint proxy statement/prospectus and Weatherford's other filings with
the Commission and public releases contain statements relating to future results
of Weatherford, including certain projections and business trends. Weatherford
believes these statements constitute "forward-looking statements" as defined in
the Private Securities Litigation Reform Act of 1995.
    
 
   
     Certain risks and uncertainties may cause actual results to be materially
different from projected results contained in forward-looking statements in this
joint proxy statement/prospectus. Such risks and uncertainties include, but are
not limited to, the following:
    
 
   
          Changes in Market Conditions Could Affect Projected Results. Any
     unexpected material changes in oil and gas prices or other market trends
     would likely affect the forward-looking information contained or
     incorporated by reference in this joint proxy statement/prospectus.
     Weatherford's
    
 
                                       21
<PAGE>   25
 
   
     estimates as to future results and industry trends make assumptions
     regarding the future prices of oil and gas and their effect on the demand
     and pricing of Weatherford's products and services. Weatherford has made
     the following assumptions:
    
 
   
          - Average prices for oil in 1999 will be within the same general range
     of prices as they were in 1998.
    
 
   
          - Average natural gas prices for 1999 will remain at or near their
     current levels.
    
 
   
          - Client budgets will be down for most of 1999.
    
 
   
          - World demand for oil will be up marginally or flat.
    
 
   
          - Drilling activity will not begin recovering until the third or
     fourth quarter of 1999.
    
 
   
     These assumptions are based on various macro economic factors and actual
     market conditions could vary materially from those assumed.
    
 
   
          Decline in Rig Count Could Affect Demand for Weatherford's Products. A
     material drop in the current worldwide rig count or drilling activity would
     likely affect the demand for Weatherford's products that are related to the
     worldwide rig count. Weatherford's forward-looking statements regarding its
     drilling products, such as drill pipe and other drill stem products, assume
     there will not be any further material declines in the worldwide rig count,
     in particular the foreign rig count.
    
 
   
          Market Conditions Could Affect Timing of Demand for Weatherford's
     Products. The timing of the improved demand for Weatherford's premium
     tubular products will be subject to the market conditions described above.
     Forward-looking statements regarding such products assume customers have
     deferred purchases of new products due to industry conditions and that
     purchases will increase in mid 1999 as inventory levels decline.
    
 
   
          Projected Merger Cost Savings Could Be Less than Weatherford Has
     Projected. The ability of Weatherford to achieve cost savings from the
     recent merger between EVI, Inc. and Weatherford Enterra, Inc. and from
     actions taken to reduce overhead costs will be dependent on market
     conditions becoming more stable. Weatherford's forward-looking statements
     regarding cost savings and their impact on Weatherford assume savings from
     the merger between EVI, Inc. and Weatherford Enterra, Inc. and from actions
     taken to reduce overhead costs in light of current market conditions.
    
 
   
          Benefits of Mergers and Acquisitions May Not Be Fully Realized. The
     full benefits of integrating the operations of EVI, Inc. and Weatherford
     Enterra, Inc., as well as integrating the various acquisitions that
     Weatherford completed over the past years, in particular synergistic
     growth, may not be fully realized until market conditions improve. The
     benefits of these combinations also depend on Weatherford's ability to
     penetrate new and existing markets with the new products and services
     acquired in the transactions. Weatherford currently is integrating such
     operations and acquisitions, which is a time consuming process that creates
     various inefficiencies during implementation. Weatherford has assumed that
     most of its 1997 and 1998 transactions will be substantially integrated by
     mid 1999.
    
 
   
          Weatherford's Success Is Dependent upon Technological
     Advances. Weatherford's ability to succeed in its long-term growth strategy
     is dependent on the technological competitiveness of its product offering.
     A central aspect of Weatherford's growth strategy is to enhance the
     technology of its products and services and to enter new markets and expand
     in existing markets with technologically advanced value-added products.
     Weatherford's forward-looking statements have not assumed any material
     near-term growth from these products.
    
 
   
          Unexpected Year 2000 Problems Could Have an Adverse Financial Impact
     on Weatherford. Weatherford has not fully determined the impact of Year
     2000 on its systems and products, and unexpected problems associated with
     the Year 2000 could arise during the implementation of its Year 2000
     program that could have a material adverse effect on Weatherford's
     business, financial condition
    
 
                                       22
<PAGE>   26
 
   
     and results of operations. Weatherford currently is in the assessment and
     initial implementation phases of its Year 2000 program.
    
 
   
          Economic Downturn in Asia Could Adversely Affect Demand for
     Weatherford's Products and Services. If the economic downturn in Asia were
     to cause the economies in the United States, Europe or South America to
     materially decline, the demand and price for oil and gas and Weatherford's
     products and services would fall and adversely affect the revenues and
     income of Weatherford. Weatherford has assumed that a worldwide recession
     will not occur as a result of the economic downturn in Asia. A material
     decline in the Chinese economy or devaluation of its currency could cause
     further deterioration to the Asian and world economies.
    
 
   
          Worldwide Political Instability Could Adversely Affect Demand for
     Weatherford's Products and Services. Any unexpected material political
     event that would affect the industry or particular oil producing countries
     in which Weatherford operates would change the base assumptions for
     Weatherford's forward-looking statements regarding the industry and
     Weatherford's position in it. Many of the world's oil and gas reserves are
     located in countries or regions that are subject to political instability.
     Weatherford has assumed in its forward-looking statements that there will
     not be any material political event that would affect the demand and
     pricing of oil and natural gas or the ability of Weatherford to provide its
     products and services worldwide.
    
 
   
          Currency Fluctuations Could Have a Material Adverse Financial Impact
     on Weatherford. A material decline in currency rates could affect
     Weatherford's future results as well as affect the carrying values of its
     assets. World currencies have been subject to much volatility.
     Weatherford's forward-looking statements assume no material impact from
     changes in currencies in its markets because Weatherford's operations are
     either dollar based, paid for in local currencies or hedged.
    
 
   
          Changes in Global Trade Policies Could Adversely Impact Weatherford's
     Operations. Changes in global trade policies in Weatherford's markets could
     impact Weatherford's operations in that market. In addition, a removal of
     currently existing anti-dumping duties in the United States with respect to
     foreign drill pipe could adversely affect Weatherford's United States sales
     of drill pipe. Weatherford has assumed that there will be no material
     changes in global trading policies.
    
 
   
          Unexpected Litigation and Legal Disputes Could Have a Material Adverse
     Financial Impact on Weatherford. If Weatherford experiences unexpected
     litigation or unexpected results in its existing litigation having a
     material effect on results, the accuracy of the forward-looking statements
     would be affected. Weatherford's forward-looking statements assume that
     there will be no such unexpected litigation or results.
    
 
   
     Finally, Weatherford's future results will depend upon various other risks
and uncertainties, including, but not limited to, those detailed in
Weatherford's filings with the Commission. For additional information regarding
risks and uncertainties relating to Weatherford and Christiana, see
Weatherford's filings with the Commission under the Securities Exchange Act of
1934, as amended (the "Exchange Act"), and the Securities Act of 1933, as
amended (the "Securities Act"), referenced under "Where You Can Find More
Information".

                     QUESTIONS AND ANSWERS ABOUT THE MERGER
 
   
     The following questions and answers highlight selected information
regarding the merger and related transactions described in this joint proxy
statement/prospectus and may not contain all information that is important to
you as you consider the merits of the merger. For a more complete description of
the terms of the merger and the related transactions, please read this entire
joint proxy statement/prospectus and the documents to which we refer. See also
"Where You Can Find More Information".
    
 
Q:  I THOUGHT THE CHRISTIANA AND WEATHERFORD STOCKHOLDERS HAD ALREADY APPROVED
    THE MERGER. WHY ARE WE VOTING AGAIN?
 
A:  You are right. The Weatherford and Christiana stockholders approved a merger
    between Christiana and a subsidiary of Weatherford pursuant to the prior
    merger agreement. We, however, were unable to complete that merger because
    the merger would not have qualified as a partially tax free reorganization
    for U.S. federal income tax purposes. As a result, we have changed the terms
    of the merger with the objective of allowing the merger to be completed on a
    partially tax free basis.
 
Q:  COULD YOU EXPLAIN WHY THE PREVIOUSLY APPROVED MERGER WOULD NOT HAVE BEEN TAX
    FREE?
 
A:  For the merger to qualify as a partially tax free reorganization for U.S.
    federal income tax purposes, the value of the Weatherford common stock at
    the time of the merger must represent at least 80% of the value of the
    consideration to be paid to the Christiana shareholders. Since the time we
    first entered into the prior merger agreement, the market price of the
    Weatherford common stock has declined by over 50%. This decline resulted in
    the value of the Weatherford common stock being less than 80% of the total
    consideration to be paid in the merger. As a result, the prior merger could
    not have been consummated on a partially tax free basis.
 
Q:  HOW WERE THE TERMS OF THE PRIOR MERGER AGREEMENT CHANGED TO ADDRESS THIS TAX
    ISSUE?
 
   
A:  We are increasing the number of shares of Weatherford common stock to be
    issued in the merger and decreasing the cash component of the merger. To
    make this change, Christiana agreed to spend up to $15.0 million to purchase
    additional shares of Weatherford common stock to the extent necessary to
    allow the merger to qualify as a partially tax free reorganization. In
    exchange, Weatherford agreed to eliminate a $10.0 million five year cash
    hold back.
    
 
Q:  WHAT ARE THE TAX SAVINGS TO BE RECEIVED BY THE CHRISTIANA SHAREHOLDERS?
 
   
A:  If the Weatherford common stock held by Christiana had been sold over the
    last year, the taxes paid by Christiana would have ranged between $4.00 and
    $21.00 per share of Christiana common stock.
    
 
   
Q:  WHY IS CHRISTIANA GIVING WEATHERFORD A ONE-THIRD INTEREST IN TLC FOR WHAT
    APPEARS TO BE NO CONSIDERATION?
    
 
   
A:  The one-third interest in TLC is being provided to Weatherford as
    consideration for entering into the transaction with Christiana. Although
    this interest has a book value in excess of $7.0 million, the Christiana
    Board believes that the benefits of the transaction, in particular the tax
    savings to be realized by the Christiana shareholders in the transaction,
    are greater than the value of the one-third interest in TLC.
    
 
   
Q:  WHY IS WEATHERFORD ACQUIRING A COMPANY ENGAGED IN THE LOGISTICS BUSINESS?
    WHAT SYNERGIES ARE THERE FOR WEATHERFORD IN THIS TRANSACTION?
    
 
   
A:  Weatherford is acquiring Christiana and the one-third interest in Logistic
    because Weatherford believes it to be a good passive investment for
    Weatherford. Weatherford does not intend to take an active management role
    in the day-to-day operations of TLC and expects the value of the TLC
    business to increase. Any increase in value would further benefit the
    Weatherford stockholders.
    
 
                                       24
<PAGE>   28
 
   
Q:  WILL THE OUTSTANDING SHARES OF WEATHERFORD COMMON STOCK CHANGE AS A RESULT
    OF THE MERGER?
    
 
   
A:  No. The number of shares of Weatherford common stock to be issued in the
    merger will equal the number of shares of Weatherford common stock held by
    Christiana.
    
 
   
Q:  WHAT IS THE RELATIONSHIP BETWEEN THE PUBLIC OFFERING BEING MADE BY C2 AND
    THE MERGER?
    
 
   
A:  The public offering by C2 is a separate transaction. It is being made to all
    the shareholders of Christiana to allow them to participate in an investment
    in TLC as part of the transaction. If you as a Christiana shareholder do not
    invest in C2, your only remaining interest in TLC will be through the
    one-third interest held by Weatherford. You will, however, receive cash that
    may be utilized by you as you wish.
    
 
   
Q:  WHY IS THE TWO-THIRDS INTEREST IN TLC BEING SOLD TO C2 AT A PRICE LESS THAN
    BOOK VALUE?
    
 
   
A:  The Christiana Board and Christiana Independent Committee have authorized
    the sale of a two-thirds interest in TLC at a price less than book value for
    the following reasons:
    
 
          - First, the two-thirds interest will be restricted and subject to
     certain rights of Christiana.
 
          - Second, C2 will assume Christiana's historical and contingent
     liabilities as part of the consideration for the purchase.
 
          - Third, C2 will agree to give Christiana a $7.0 million put right for
     its interest.
 
   
          - Fourth, all Christiana shareholders will be entitled to invest in
     TLC through C2 on the same basis.
    
 
Q:  WHAT SHOULD I DO NOW?
 
A:  After reading this document carefully, you should complete and sign your
    proxy card and mail it in the enclosed return envelope as soon as possible,
    so that your shares may be represented at the special meetings. The Board of
    Directors of Christiana recommends that the Christiana shareholders vote for
    adoption of the merger agreement and the merger. The Board of Directors of
    Weatherford recommends that the Weatherford stockholders vote for adoption
    of the merger agreement and the merger.
 
Q:  SHOULD I SEND MY STOCK CERTIFICATES NOW?
 
   
A:  No action needs to be taken by the Weatherford stockholders. Christiana
    shareholders should complete the letter of transmittal that accompanies this
    joint proxy statement/prospectus and return it, along with their Christiana
    stock certificates, to Firstar Bank Milwaukee, N.A. at the address listed in
    the letter of transmittal by no later than 5:00 p.m., central standard time,
    on      --   , 1999. Christiana shareholders who submitted their Christiana
    stock certificates in connection with the first special meeting of
    Christiana shareholders to consider the merger need not take any action
    regarding those certificates but should still complete and return the letter
    of transmittal.
    
 
Q:  IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
    SHARES FOR ME?
 
A:  Your broker will vote your shares only if you provide instructions on how to
    vote. You should follow the directions provided by your broker regarding how
    to instruct your broker to vote your shares.
 
Q:  MAY I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD?
 
   
A:  Yes. You can change your vote by sending in a later-dated, signed proxy card
    to the Secretary of your company before the special meetings or by attending
    your special meeting and voting in person.

<PAGE>   29
 
Q:  WHAT OTHER MATTERS WILL BE VOTED ON AT THE SPECIAL MEETINGS?

    special meetings to solicit additional votes if they have not received the
    required votes by the time of the special meetings. We do not expect to ask
    you to vote on any other matters at the special meetings.

VOTE REQUIRED
 
     Weatherford. Weatherford's Amended and Restated By-laws provide that if a

special meeting, in person or by proxy, then there will be a quorum to transact
business. Under Weatherford's listing agreement with the NYSE, a majority of
Weatherford shares present, in person or by proxy, and entitled to vote must

                                       27
<PAGE>   31
 
     Christiana. Under Wisconsin law, both the holders of 80% of the outstanding
shares of Christiana common stock and two-thirds of the shares of Christiana
common stock other than shares held by the Lubar family must approve and adopt
the merger proposal. This means at least 31.6% of the shares of Christiana
common stock other than shares held by the Lubar family must approve the merger.
 
     At the close of business on the record date, there were 5,149,330 shares of
Christiana common stock outstanding and entitled to vote at the Christiana
special meeting. At the close of business on the record date, the directors and
officers of Christiana and their affiliates held 3,445,932 shares of Christiana
common stock, representing an aggregate of approximately 67% of the outstanding
shares. These directors and officers indicate they will vote their shares to
approve the merger proposal.
 
VOTING AND REVOCATION OF PROXIES
 
     Management will vote all properly executed proxies that are not revoked at
the special meetings in accordance with the instructions contained therein. If
you execute and return a proxy and do not specify otherwise, the shares
represented by your proxy will be voted "FOR" approval and adoption of the
merger proposal in accordance with the recommendation of the Weatherford Board
of Directors and the Christiana Board of Directors, as applicable. If you check
the abstention box on the proxy card or fail to return the proxy card, it has
the same effect as voting against the merger proposal and the proposal relating
to any adjournments of the respective special meeting. You may revoke your proxy
at any time before it is voted at the respective special meeting by executing
and returning a proxy bearing a later date, by filing written notice of such
revocation with the Secretary of Weatherford or Christiana, as appropriate,
stating that you revoke the proxy or by attending the special meeting and voting
in person.
 
     Under NYSE rules, brokers may not submit proxies authorizing a vote on the
merger proposal without specific instructions from beneficial owners. An
abstention will have the effect of a vote against the merger proposal. A broker
nonvote will have the effect of a vote against the merger proposal. Under
Delaware law and Wisconsin law, both abstentions and broker nonvotes contained
on a returned proxy card will be considered present for purposes of determining
the existence of a quorum at the Weatherford special meeting or the Christiana
special meeting.
 
SOLICITATION OF PROXIES
 
     Weatherford retained Georgeson & Company, Inc., to help it solicit proxies
at a cost of $6,500 plus expenses. Christiana retained D.F. King & Co. to help
it solicit proxies at a cost of $7,500 plus expenses. In addition to
solicitation by mail, the directors, officers and employees of Weatherford and
Christiana may solicit proxies from their respective stockholders by personal
interview, telephone, facsimile or otherwise.
 
   
     Christiana will bear the costs incurred in soliciting the proxies from both
the Weatherford and Christiana stockholders. We will both arrange for brokerage
firms and other custodians, nominees and fiduciaries who hold the voting
securities of record to forward the solicitation materials to the beneficial
owners of those securities. We will reimburse such brokers, custodians, nominees
and fiduciaries for the reasonable out-of-pocket expenses they incur in
forwarding these solicitation materials.
    
 
DISSENTERS' RIGHTS
 
     Under Delaware law, the holders of Weatherford common stock who object to
the merger proposal or abstain from voting in favor of the merger proposal will
not have any appraisal rights or right to receive cash for their shares of
Weatherford common stock and Weatherford does not intend to make any such rights
available to its stockholders.
 
     Under the provisions of Wisconsin law, any Christiana shareholder who
dissents from the merger will have a statutory right to demand the "fair value"
of such shareholder's Christiana common stock in cash. To exercise this right,
such shareholder must not vote its shares in favor of the merger and must take
 
                                       28

certain other actions required by the provisions of Subchapter XIII of the
Wisconsin Business Corporation Law. See "The Merger -- Dissenters' Rights".
 
OTHER MATTERS
 
     As of the date of this Joint Proxy Statement/Prospectus, the Weatherford
Board of Directors and the Christiana Board of Directors do not know of any
business to be presented at their respective special meetings other than as
stated in the notices accompanying this Joint Proxy Statement/Prospectus. If any
other matters should properly come before the respective special meetings,
including a proposal to adjourn such special meetings, management intends to
vote the shares represented by the proxies with respect to such matters
according to its judgement as to the merits of such matters.

                         BACKGROUND OF THE TRANSACTION
 
     On June 30, 1995, Weatherford acquired Prideco, Inc. ("Prideco") from
Christiana and other stockholders of Prideco in consideration for the issuance
of approximately 4.5 million shares of Weatherford common stock. As part of this
acquisition, Christiana received 3,897,462 shares of Weatherford common stock
and Sheldon Lubar, Chairman of the Board of Christiana, was appointed to the
Board of Directors of Weatherford. Christiana also was given the right to name a
nominee for election to the Board of Directors of Weatherford as long as
Christiana's interest in Weatherford was equal to at least 8% of the outstanding
shares of Weatherford common stock.
 
   
     In earlier years, Christiana developed commercial and residential
properties, including projects in California, Nevada, Georgia and Texas. In
1987, the Christiana Board of Directors decided that the Company should be
involved in other businesses, because of the opportunity for more favorable
returns. Consequently, Christiana began a program of disposing of its real
estate properties and reinvesting its available cash into other businesses,
including TLC's warehousing and logistics business. As a result of this internal
restructuring, Christiana consisted primarily of two unrelated assets:
    
 
   
     - Its warehousing and logistics business.
    
 
   
     - Its Weatherford shareholdings.
    
 
   
     Christiana's Board of Directors considered it desirable to separate the two
operations in order that Christiana be viewed as either a warehousing and
logistics business or a company involved in the engineered oilfield tools and
equipment business by virtue of its Weatherford shareholdings. Over the past
year, the value of Christiana stock in the market reflected primarily the
underlying asset value of its Weatherford shareholdings and did not adequately
reflect the value of its warehousing and logistics business. The Christiana
Board was aware that a sale of the warehousing and logistics business would
likely result in Christiana becoming a single business holding company and
subjecting Christiana to investment company regulations, which was not an
objective of the Christiana Board. Further, if the shares of Weatherford common
stock were sold or distributed to the Christiana shareholders, significant taxes
would be incurred at the corporate level and further at the shareholder level.
The Christiana Board considered, but rejected, an outright sale of Christiana,
because this would transfer ownership, but not separate the two businesses. The
Board considered, but rejected, a sale of TLC's warehousing and logistics
business, because the result would leave Christiana as a nonoperating holding
company. The Christiana Board also considered, but rejected, a sale of the
Weatherford shareholdings, because of Christiana's view as to the future
potential for increase in the value of the asset and the substantial
corporate-level tax that would result from such a sale. The Christiana Board
ultimately determined that a tax free merger would accomplish many of the
objectives described above.
    
 
   
     In early June 1997, Mr. Lubar informally advised Christiana Board members
that he intended to approach Weatherford to inquire as to Weatherford's interest
in acquiring Christiana. The Christiana Board members informally concurred that
this was appropriate and requested that Mr. Lubar keep them advised and schedule
a formal meeting at an appropriate date to discuss such matter. At this time
there was no intention on the part of Mr. Lubar or any other officer or director
of Christiana or TLC to purchase TLC. Christiana, however, was not certain that
Weatherford would be willing to acquire Christiana with a controlling management
interest in TLC. In considering a possible acquisition of Christiana by
Weatherford, the Christiana Board of Directors took into account that if
Weatherford were not willing to acquire a controlling management interest in
TLC, Christiana would be required to dispose of a controlling interest in TLC
prior to the acquisition. In such case, the Lubar family and members of
Christiana and TLC management were willing to consider purchasing such portion
if that became necessary to complete a merger with Weatherford.
    
 
     On June 19, 1997, Messrs. Sheldon Lubar and Donovan sent a memorandum to
Messrs. Brady, Nicholas and David Lubar describing in more detail the
restructuring of Christiana focusing on providing shareholders with enhanced
value in a tax efficient manner. The valuation of the components of Christiana,
as well as tax liabilities and the basis of Christiana's assets, were
considered. Messrs. Brady, Nicholas,
 
                                       30
<PAGE>   34
 
D. Lubar, S. Lubar and Donovan conferred by telephone on June 20, 1997 and
concurred that a tax free merger with Weatherford was desirable. Messrs. S.
Lubar and Donovan advised the other directors that a meeting was scheduled with
Mr. Bernard Duroc-Danner, President of Weatherford, on June 23, 1997, in
Milwaukee, Wisconsin, and discussed with them the basis upon which a merger with
Weatherford would be most beneficial to Christiana shareholders.
 
   
     In early June 1997, Mr. Lubar approached Mr. Duroc-Danner to inquire as to
Weatherford's interest in acquiring Christiana in a tax free merger. At a
meeting held in Milwaukee on June 23, 1997, at which Messrs. Lubar, Donovan and
Duroc-Danner were present, the parties discussed the possible acquisition.
Messrs. Lubar and Donovan expressed flexibility from Christiana's standpoint as
to the structure of the transaction and the mix of the consideration between
stock and cash that would be received by the Christiana shareholders. Following
that meeting, Weatherford and Christiana directed their legal and tax advisors
to review the possibility of an acquisition of Christiana by Weatherford and any
issues relating thereto.
    
 
     Following a review of issues involved in an acquisition by Weatherford of
Christiana, in July 1997, Mr. Duroc-Danner advised Mr. Lubar of Weatherford's
management's interest in Weatherford pursuing a possible acquisition of
Christiana on appropriate terms, including, specifically, an acquisition that
would not be dilutive to Weatherford's per share earnings or cash flow and that
would not involve Weatherford's full ownership and management of Christiana's
warehousing and logistics business, and that the ownership and management of
Christiana's warehousing and logistics business would be inconsistent with the
operations of Weatherford and Weatherford's focus on the oilfield manufacturing
and service business. Weatherford also advised Christiana that Weatherford would
need to receive confirmation that an acquisition of Christiana by Weatherford
would not adversely affect Weatherford's ability to consummate any future
acquisition that would be accounted for as a pooling of interests, in particular
Weatherford's then pending acquisition of XLS Holding, Inc. ("XL").
 
   
     Following these discussions, Messrs. Duroc-Danner and Lubar agreed that the
most appropriate structure for an acquisition by Weatherford of Christiana would
involve a transaction in which a controlling interest in TLC's business would be
sold to another entity for cash prior to Weatherford's acquisition and the
consideration that would be paid to the Christiana shareholders in the
acquisition would consist solely of a number of shares of Weatherford common
stock equal to the number of shares of Weatherford common stock held by
Christiana and an amount of cash not greater than the amount of cash held by
Christiana in excess of its existing obligations.
    
 
     During discussions with Weatherford, Mr. Lubar routinely advised Christiana
directors regarding such discussions. Informal Christiana Board communications
consisted primarily of individual telephone calls between Mr. Sheldon Lubar and
Messrs. Nicholas F. Brady and Albert O. Nicholas, Christiana directors. Messrs.
Sheldon Lubar, David Lubar, a Christiana director, and William T. Donovan,
Christiana's President and a director, had extensive discussions on a daily
basis during these periods. Mr. Donovan also had telephone conversations with
the other Christiana directors, Messrs. Brady and Nicholas, and with John R.
Patterson and Gary R. Sarner, to discuss progress and solicit input in the
evaluation process and to update the Christiana Board on negotiations with
Weatherford. Although members of the Christiana Board were consulted during this
process, Christiana did not hold any meetings of the Board in person or
telephonic meetings of the Board relating to the merger at this time.
 
   
     During the course of the negotiations, Weatherford imposed additional
requirements in connection with any proposed transaction, including the
following:
    
 
   
     - The entity that would acquire a controlling interest in TLC must be a
       creditworthy entity acceptable to Weatherford, because such an entity
       must assume significant liabilities in connection with Christiana's and
       TLC's present and prior businesses.
    
 
   
     - The acquiring entity must agree to certain operational restraints in
       order to increase the likelihood that such an entity would be able to
       satisfy all assumed liabilities.
    
 
   
     - A substantial holdback be available as security for such assumption of
       liabilities.
    
 
                                       31
<PAGE>   35
 
     The imposition of each of the foregoing decreased the desirability of the
transaction to Christiana. In periodic telephone conversations with Messrs.
Nicholas and Brady and in frequent conversations with Messrs. Patterson and
Sarner, Messrs. Lubar and Donovan advised them of the increasing requirements of
Weatherford. On numerous occasions the directors were asked their opinion of
whether the conditions imposed by Weatherford were decreasing the desirability
of Christiana's completing a proposed transaction. The conclusion reached in the
discussions with the directors was that Messrs. Lubar and Donovan should
continue the negotiations, making as few concessions as possible.
 
     During this interaction with Christiana Board members, Messrs. Lubar and
Donovan gave special attention to the views of Messrs. Nicholas and Brady,
because each owned a significant interest in Christiana, but were not employees.
While neither director was directly involved in negotiations with Weatherford,
they were advised as to the increasing conditions required by Weatherford as the
basis for a contemplated transaction. The views of Messrs. Nicholas and Brady of
the negotiations was important for Christiana, because, without their
concurrence, Messrs. Lubar and Donovan decided that they would not proceed with
a transaction with Weatherford.
 
   
     In conversations with the other Christiana directors, Messrs. Lubar and
Donovan specifically discussed the appropriateness of a payment of $10.67
million to be paid to Christiana for a two-thirds interest in TLC. In
particular, Messrs. Donovan, Sarner and Patterson considered the operations of
TLC and the impact on its liabilities, including the liabilities that it would
have to assume in order to satisfy Weatherford's requirements and the
operational restrictions under which it would have to operate in order to
satisfy Weatherford. Messrs. Lubar and Donovan concluded that it was highly
unlikely that any outside party would be willing to enter into a transaction on
a basis acceptable to Weatherford. For these reasons they concluded that $10.67
million cash for a two-thirds interest in TLC was appropriate. The
appropriateness of the $10.67 million payment by C2 for a two-thirds interest in
TLC and the adequacy and fairness of that payment was discussed and approved by
the full Christiana Board of Directors at its meeting held on November 21, 1997.
    
 
     No alternative acquisition structures were discussed or considered in that
the above form of transaction was the only form of transaction that would meet
the objectives of Weatherford in the transaction. The specific amount of cash
that would be provided to the Christiana shareholders in such a transaction was
not agreed to at that time. Because of Mr. Lubar's interest in both Christiana
and Weatherford, as well as Christiana's ownership interest in Weatherford, Mr.
Duroc-Danner advised Mr. Lubar that he believed that the review of the
transaction and the determination of the consideration to be received should be
approved and considered by a special committee of Weatherford.
 
   
     The Christiana Board of Directors did not consider a sale of all of TLC to
facilitate Weatherford's desire not to acquire a controlling interest in TLC
because:
    
 
   
     - Such a sale could have impacted the ability to effect the merger as a
       partially tax free reorganization.
    
 
   
     - Weatherford required Christiana to have assets other than Weatherford
       common stock at the time of the merger in order to proceed with the
       proposed transactions.
    
 
   
     The Christiana Board also did not consider an auction of the two-thirds
interest in TLC that Weatherford did not wish to acquire because of the
perceived difficulty that would be involved in selling only a portion of the
ownership interest in TLC. In particular, the Christiana Board of Directors
believed that the indemnification requirements, the distribution, operation and
management restrictions and the tag-along and change in control provisions and
Weatherford put rights would materially reduce the desire of a third party to
acquire an interest in TLC and would affect materially the consideration that
would be received. Accordingly, the Christiana Board of Directors concluded that
a sale of a two-thirds interest in TLC to Mr. Lubar or one or more of his
affiliates at a fair price reflecting these restrictions would be in the best
interest of Christiana in that it would allow Christiana to effect the merger
with Weatherford and receive a fair value for the interest in TLC that
Weatherford was not willing to acquire. Mr. Lubar, in his
    
 
                                       32
<PAGE>   36
 
capacity both as a director of Christiana and a potential interested party
through his agreement to assist in the funding of C2, took part in these
discussions with the Christiana Board.
 
   
     To facilitate the consideration of a possible acquisition of Christiana by
Weatherford, Messrs. Lubar and Donovan on behalf of Christiana proposed to
Weatherford that the consideration to be paid by Weatherford in the acquisition
would consist of the following:
    
 
   
     - A number of shares of Weatherford common stock equal to the number of
       shares of Weatherford common stock held by Christiana.
    
 
   
     - An amount of cash equal to the amount of cash of Christiana in excess of
       Christiana's fixed liabilities, including $20.0 million from a cash
       dividend that would be paid by TLC to Christiana prior to the sale of a
       two-thirds interest in TLC and approximately $10.67 million cash to be
       paid to Christiana for such two-thirds interest in TLC.
    
 
   
This proposal also contemplated that, following the acquisition, Christiana's
only assets would consist of the shares of Weatherford common stock then
currently held by Christiana, a one-third interest in TLC following the $20.0
million distribution and cash equal to the amount of cash payable by Weatherford
to the Christiana shareholders in the merger. Mr. Lubar also advised Weatherford
and Christiana that to facilitate the transaction, he and his affiliates would
be willing to acquire the two-thirds interest in TLC at the $10.67 million price
and cause the acquiring entity and TLC to assume certain obligations of
Christiana.
    
 
   
     Mr. Lubar decided that $10.67 million for a two-thirds interest in TLC was
a fair price. This price for a two-thirds interest would correspond to a price
for 100% of the equity interest in TLC of $16.0 million. Christiana's management
and Board determined the $16.0 million equity value principally by employing a
multiple of "operating cash flow" produced by the business of TLC. "Operating
cash flow" was generally considered to be earnings before interest, taxes,
depreciation and amortization. In fiscal 1997, TLC produced $13.1 million in
"operating cash flow". The multiple employed to determine the total enterprise
value was six, which was based on the assessment of Christiana's management and
Board of the various components of TLC's earnings, i.e., transportation, dry
public warehousing, public refrigerated warehousing and international services.
No financial analysts were consulted in determining such price. This produced an
enterprise value for TLC of $78.6 million from which the anticipated level of
debt of $63.0 million was subtracted, giving an equity value of TLC of $15.8
million (rounded up to $16.0 million). Two-thirds of this value is $10.67
million. The consideration as to the appropriate cash flow multiple of six for
purposes of the calculation of the purchase price for a two-thirds interest in
TLC and the anticipated level of debt was determined by Mr. Donovan on behalf of
Christiana and C2 and conveyed to the full Christiana Board of Directors.
Afterward, the Christiana Board of Directors took into account the advice of Mr.
Donovan with respect to such cash flow multiple when it approved the transaction
at the meeting held on November 21, 1997. The Board of Directors of Christiana
concluded that a higher price for TLC would not be warranted for a number of
reasons, including the following:
    
 
   
     - TLC would be required to assume debt of approximately $63.0 million, in
      part to pay a cash dividend of $20.0 million to Christiana.
    
 
   
     - While the proposed sale price of the two-thirds interest in TLC was
      approximately $4.54 million less than its book value as of June 30, 1997,
      the Christiana Board of Directors believed that the liability assumption
      obligations and restrictions imposed by Weatherford supported a sale below
      book value. The Christiana Board of Directors, however, also believed that
      the cost to Christiana for disposing of such interest at that price
      represented a fair discount for the assumption of obligations and
      restrictions imposed by Weatherford. The Christiana Board of Directors
      further believed that any lower amount of consideration that would be
      received by the Christiana shareholders from the proposed sale of the
      two-thirds interest in TLC in the manner contemplated was more than offset
      by the benefits to be realized by the Christiana shareholders in the
      merger and their receipt of Weatherford common stock in a tax free manner.
    
 
                                       33
<PAGE>   37
 
   
     - The purchasing entity and TLC would be required to assume various
      contingent and unquantifiable liabilities, including liabilities related
      to the historical operations of Christiana, TLC and other companies
      formerly owned by Christiana.
    
 
   
     - TLC would be required to restrict its operational activities for the
      benefit of Weatherford and consequently would not have complete freedom in
      connection with its business operations. Such restrictions were expected
      to include prohibitions on any of the following without approval by
      Weatherford: cash distributions, noncash distributions, acquisitions,
      liquidation and compensation. These restrictions were eventually agreed
      upon in the operating agreement to govern TLC following the transaction.
      See "Related Party Transactions -- Terms of the Operating Agreement".
    
 
   
     - No right was available to acquire the remaining one-third interest in
      TLC.
    
 
   
     - It was contemplated that Weatherford would have the ability to put its
      one-third interest to TLC, thereby decreasing the value of TLC.
    
 
   
     Weighing the above factors, the price of $10.67 million for a two-thirds
interest in TLC was the highest price Mr. Lubar thought appropriate.
Furthermore, considering that the purchasing entity would have to be acceptable
to Weatherford, Mr. Lubar felt it highly unlikely that a transaction could be
concluded with any other entity paying the same or higher price for the
two-thirds interest in TLC. Mr. Lubar reached this conclusion because, in order
to conclude a transaction on such a basis, any acquirer would have to meet the
following criteria:
    
 
   
     - Be acceptable to Weatherford from a financial and operational standpoint.
    
 
   
     - Be willing to assume indemnity obligations to Weatherford relating to the
      historical operations of TLC, Christiana and other companies formerly
      owned by Christiana.
    
 
   
     - Be willing to acquire less than a 100% interest in TLC.
    
 
   
     - Be willing to accept a put obligation on the one-third interest retained
      by Christiana.
    
 
   
     - Be willing to accept restricted operational activities.
    
 
   
Mr. Lubar considered the chances of fulfilling the above conditions remote. As a
result, no consideration was given by the Christiana Board of Directors to a
sale of TLC to a bidder other than Weatherford.
    
 
   
     The Christiana Board of Directors also determined that a discount of $4.54
million off the then existing book value for a two-thirds interest in TLC was an
appropriate discount for a sale of a two-thirds interest in TLC to C2 (and Mr.
Lubar through his proposed interest in C2) due to the fact that a two-thirds
interest in TLC would be generally illiquid and the factors considered by Mr.
Lubar described in second through fifth clauses in the prior paragraph. Although
the impact of these factors was not subject to precise quantification, the
Christiana Board of Directors believed that the discount, which was in large
part reflective of the six times cash flow multiple discussed and suggested by
Mr. Donovan as described above, was fair to the Christiana shareholders.
    
 
     In July 1997, Mr. Donovan commenced discussions with investment bankers
regarding potential financial advisory roles. These discussions culminated with
the retention of Prudential Securities on November 24, 1997 as financial advisor
to Christiana.
 
   
     On August 14, 1997, Mr. Lubar advised the Christiana Board of Directors of
the potential for a merger with Weatherford. The Christiana Board determined
that it was not necessary to appoint a special committee at that time, even
though Mr. Lubar was expected to own a significant interest in an entity that
would purchase TLC in connection with the merger. The Christiana Board noted
that the outside directors, Messrs. Nicholas and Brady, were in favor of the
prior merger agreement and that the prior
    
 
                                       34
<PAGE>   38
 
   
merger agreement would not be approved without their concurrence. The views of
Messrs. Nicholas and Brady were especially important for two reasons. First,
unlike the other directors, they were not employed by Christiana or TLC. Second,
each held a significant interest in Christiana (9.9% in the aggregate) and
therefore their interests would be aligned with other shareholders. The
directors decided that it was important for all shareholders to know how each
director voted on this issue. Each director voted in favor of continuing the
negotiations. Because the two unaffiliated directors, Messrs. Nicholas and
Brady, voted in favor of continuing the negotiations, Messrs. Lubar and Donovan
had sufficient authority under applicable Wisconsin law to proceed even though
the "affiliated" directors voted. During this period and until the November 21,
1997 Christiana Board meeting at which the Board of Directors of Christiana
approved the merger, Messrs. Lubar and Donovan kept the Christiana Board advised
of the progress of negotiations, including specifically the outside directors,
Messrs. Nicholas and Brady.
    
 
   
     After having been advised by Weatherford that Weatherford would be
interested in owning only a one-third interest in TLC, Christiana and its Board
of Directors began to consider what entity would own the remaining two-thirds
interest in TLC.
    
 
     On August 21, 1997, at the recommendation of Mr. Duroc-Danner, the Board of
Directors of Weatherford appointed a special committee of the Board of Directors
of Weatherford consisting of Sheldon S. Gordon, a former director of
Weatherford, and Robert A. Rayne (the "Weatherford Special Committee") to review
the Christiana proposal. Following that appointment, the Weatherford Special
Committee directed Fulbright & Jaworski L.L.P., Weatherford's outside counsel
("Fulbright & Jaworski"), to begin negotiations with Christiana of an
acquisition on terms satisfactory to Weatherford.
 
     In early September, Fulbright & Jaworski and Foley & Lardner, outside
counsel to Christiana, began negotiations for the acquisition. In late
September, Weatherford advised Christiana that in light of a number of
transactions that Weatherford was then pursuing, in particular, its proposed
acquisitions of BMW Monarch (Lloydminster) Ltd. and BMW Pump, Inc.
(collectively, "BMW") and Trico Industries, Inc. ("Trico"), Weatherford was not
in a position at that time to devote the time and resources necessary to pursue
the acquisition of Christiana and that further negotiations would need to be
delayed until a later date.
 
   
     On October 1, 1997, Mr. Donovan was approached by another entity inquiring
about a potential interest in TLC. This entity was an entity known to Mr.
Donovan to have recently acquired a majority interest of a company involved in
the public refrigerated warehousing and logistics industry. Mr. Donovan
discussed with representatives of this entity the key elements of the
contemplated transactions with Weatherford. Such potential purchaser indicated
that it was not interested in considering such a transaction, primarily because
of the indemnification provisions, the lack of a right to acquire the minority
interest to be held by Weatherford and the operating restrictions imposed on
TLC.
    
 
     On October 8, 1997, following the execution of definitive agreements for
the acquisitions of Trico and BMW, Mr. Duroc-Danner met in Milwaukee with
Messrs. Lubar and Donovan to discuss the status and expected timing of
Weatherford's review of the Christiana acquisition. Mr. Duroc-Danner
subsequently contacted the members of the Weatherford Special Committee and
suggested a November 11, 1997, meeting to review and discuss the terms and
structure of the proposed transactions. Weatherford and Christiana then directed
their advisors to resume negotiations of documentation.
 
     On November 7, 1997, Weatherford engaged Morgan Stanley to provide
Weatherford with a fairness opinion on the proposed transactions.
 
   
     On November 11, 1997, the Weatherford Special Committee met in London with
Mr. Duroc-Danner, James G. Kiley, Vice President and Chief Financial Officer of
Weatherford, and representatives of Fulbright & Jaworski and Morgan Stanley to
review the status and structure of the proposed transactions. At this meeting,
the Weatherford Special Committee reviewed the outstanding issues with respect
to the proposed transactions and the financial impact to Weatherford thereof as
well as drafts of documents for the proposed transactions. The Weatherford
Special Committee also reviewed various due diligence matters relating to
Christiana and TLC, including the historical businesses of Christiana, various
matters
    
 
                                       35

relating to the prior ownership of real property by Christiana in California,
the status of various lawsuits then pending against Christiana, including a
class action lawsuit involving a prior real estate development in California
that has since been settled, and other customary matters involving the
historical business and operations of Christiana and its subsidiaries.
 
     Following the conclusion of the November 11, 1997 meeting of the
Weatherford Special Committee, the members of the Weatherford Special Committee
contacted Mr. Lubar to discuss proposed changes in the terms of the proposed
transactions. Weatherford and Christiana advisers then continued negotiation of
the terms of the proposed transactions, including the following:
 
   
     - That $10.0 million cash be retained by Christiana to be available to pay
       any unpaid indemnity claims under the TLC purchase agreement.
    
 
   
     - That $10.0 million of the cash consideration proposed by Christiana to be
       paid in the merger be deferred for five years without interest and be
       subject to reduction for any liabilities or unpaid indemnity claims that
       may be paid by Weatherford or Christiana.
    
 
   
     - That Christiana pay all printing and proxy solicitation costs as well as
       Weatherford's filing fees with the Commission and under the HSR Act and
       all costs and expenses for blue sky and state securities law filings.
    
 
   
     - That the value of various tax benefits associated with the exercises and
       termination of options by Christiana prior to the merger be provided to
       Weatherford without offset for other income by Christiana.
    
 
   
     - That Christiana obtain a solvency opinion with respect to the proposed
       transactions.
    
 
   
     - That various protections be incorporated in the operating agreement to
       protect Christiana's minority interest in TLC following the merger.
    
 
   
     - That C2 be responsible for the indemnification of the historical
       liabilities and obligations of Christiana and its current and historical
       subsidiaries and predecessors under the TLC purchase agreement as well as
       be responsible to purchase Christiana's one-third interest in TLC if
       Christiana were to elect to sell its one-third interest in TLC five years
       after the closing.
    
 
   
     The Weatherford Special Committee requested a solvency opinion because of
the various loans that were anticipated to be made to TLC to fund a portion of
the cash dividend to be made by TLC to Christiana as a condition to the merger
and given that the TLC sale involved a transaction among affiliated parties, an
independent third-party solvency opinion would provide support that the TLC sale
would not constitute a fraudulent transfer. Weatherford also conducted various
additional due diligence regarding the litigation described above. Except for
the class action lawsuit, which was subsequently settled, no known material
liabilities or contingencies were identified during the due diligence process.
    
 
     Further negotiations between the representatives of Weatherford and
Christiana with respect to open points under the agreements continued through
the month of November.
 
     On November 21, 1997, the Board of Directors of Christiana met to consider
the proposed transactions. At this meeting, representatives of Foley & Lardner
and Christiana management provided presentations to the full Board of Directors
describing the proposed transactions and the financial, legal and other effects
of the proposed transactions on Christiana. The Board considered the advantages
of the following:
 
   
     - A separation of Christiana's two principal assets, its 3,897,462 shares
       of Weatherford common stock and TLC, including permitting Christiana
       shareholders to make more focused investment decisions based on the
       specific attributes of Weatherford and Christiana, as discussed more
       fully under "Christiana's Reasons For the Transaction".
    
 
     - The fair value Christiana shareholders would receive in the merger in the
       form of the Weatherford share consideration, the cash consideration and
       the $10.0 million contingent cash payment.
 
                                       36
<PAGE>   40
 
     - The tax free nature of the Weatherford share consideration to Christiana
       shareholders.
 
   
     - The right of each Christiana shareholder to purchase his or her pro rata
       interest in C2 and thereby maintain an ownership interest in TLC. The
       Board also determined that a fairness opinion from Prudential Securities,
       based on the terms described at the meeting, would be necessary.
    
 
   
     The Christiana Board also considered the cost to the Christiana
shareholders in connection with the merger, including, specifically, that the
merger would preclude other alternatives in the future, that the $10.0 million
contingent cash payment would not bear interest, that Christiana (which
following the merger will be a wholly owned subsidiary of Weatherford) would
retain a one-third interest in TLC and the cost associated with converting the
TLC business to the business of C2. The Christiana Board further considered that
the proposed transactions would increase the exposure of Christiana shareholders
to fluctuations in the price of Weatherford common stock, as described more
fully in "Christiana's Reasons For the Transaction". The Christiana Board,
nevertheless, considered that the advantages outweighed such disadvantages. In
considering the proposed transactions, the Christiana Board of Directors also
noted that the potential tax benefits that could be realized by Christiana (and
therefore accruing to the benefit of Christiana's shareholders through the
elimination of double taxation) through the merger (versus other alternatives)
ranged from $57.8 million on August 14, 1997, the date of the Christiana Board's
first meeting to consider the potential for a merger with Weatherford, to $72.0
million on November 21, 1997, the date the Christiana Board approved the merger,
and, based on its favorable outlook on Weatherford common stock, the Christiana
Board expected these tax benefits to increase. Except for the quantification of
these tax benefits and its analysis of the potential value of TLC as described
above, the Christiana Board of Directors did not assign values or quantify
further its analysis of the transaction. Following these presentations and
discussions at the November 21, 1997 Board meeting, the Board of Directors of
Christiana unanimously approved the prior merger agreement and related
transactions (including, specifically, the sale of two-thirds of TLC to C2) and
determined that the prior merger agreement and related transactions were in the
best interest of Christiana and fair to the Christiana shareholders, including
the unaffiliated shareholders.
    
 
   
     A special committee of the Christiana Board was not established at the time
of the November 21, 1997 Board meeting because the Christiana Board noted that
the two outside directors, Messrs. Nicholas and Brady, who were present and
voting, approved the prior merger agreement and related transactions and
concluded that the merger pursuant to the prior merger agreement and related
transactions were in the best interest of Christiana. The views of Messrs.
Nicholas and Brady were especially important to Christiana for two reasons.
First, unlike the other directors, they were not employed by Christiana or TLC.
Second, each held significant interest in Christiana (9.9% in the aggregate) and
therefore their interests would be aligned with other shareholders. Because the
two unaffiliated directors, Messrs. Nicholas and Brady, voted in favor of the
merger pursuant to the prior merger agreement and related transactions, Messrs.
Lubar and Donovan had sufficient authority under applicable Wisconsin law to
proceed even though the "affiliated" directors voted. This approval was subject
to the finalization of the documentation relating to the proposed transactions,
the receipt of the opinion of Prudential Securities as to the fairness, from a
financial point of view, of the proposed transactions to the shareholders of
Christiana (the "Prudential Securities Opinion"), satisfaction of other closing
conditions and approval of the final documentation for the merger pursuant to
the prior merger agreement by the President of Christiana.
    
 
   
     The Christiana Board of Directors did not believe that it was necessary to
engage an independent third party to conduct an analysis as to the appropriate
valuation of the two-thirds interest in TLC proposed to be sold to C2 on the
basis that the Board was familiar with the business of TLC and had historical
expertise and knowledge as to financial matters. In addition, the Board of
Directors believed that, by providing the Christiana shareholders with the right
to invest in C2, the need and expense of obtaining a third party independent
valuation of TLC was not in the interest of the Christiana shareholders and
would not have provided any additional meaningful basis for determining the
fairness of the transaction to Christiana.
    
 
   
     To assure the fairness of the proposed sale of TLC to C2 at the price
contemplated by the TLC purchase agreement, Christiana required C2 to offer to
the Christiana shareholders the right to participate
    
 
                                       37
<PAGE>   41
 
   
and invest in C2 on the same terms and conditions as the Lubar family.
Christiana also required Weatherford to agree to procedural terms relating to
the payment of the cash consideration that would allow the Christiana
shareholders to apply the cash consideration payable to them directly toward the
purchase of shares of C2 common stock. The Christiana Board of Directors
believes that this right to participate in the ownership of C2 common stock
provides substantial procedural fairness to the proposed sale of TLC and allows
the Christiana shareholders to continue to participate in the ownership of TLC
if they so desire.
    
 
     On December 1, 1997, the Weatherford Special Committee met to review the
prior merger agreement. At this meeting, representatives of Fulbright & Jaworski
and Morgan Stanley provided to the Weatherford Special Committee an updated
summary of the financial, legal and other effects of the proposed transactions.
The terms of the documentation were also reviewed. Morgan Stanley further
advised the Weatherford Special Committee that it was prepared to deliver its
fairness opinion if the proposed transactions were to be effected on the terms
described at the meeting. A draft of the fairness opinion was provided and
reviewed by the Weatherford Special Committee. After discussion, the Weatherford
Special Committee determined that the proposed transactions were desirable for
Weatherford and that it would recommend to the full Board of Directors of
Weatherford that the prior merger agreement be approved.
 
     Later on December 1, 1997, the Board of Directors of Weatherford met to
consider the prior merger agreement. At this meeting, representatives of
Fulbright & Jaworski and Morgan Stanley provided presentations to the full Board
of Directors describing the proposed transactions and the financial, legal and
other effects of the proposed transactions on Weatherford. The Weatherford
Special Committee also provided a report to the Weatherford Board of Directors
outlining its findings and recommendations. Morgan Stanley further advised the
Weatherford Board of Directors that it was prepared to deliver its opinion as to
the fairness, from a financial point of view, of the consideration to be paid by
Weatherford pursuant to the Prior merger agreement (the "Morgan Stanley
Opinion"), if the proposed transactions were to be effected on the terms
described at the meeting. A draft of that opinion was provided to the Board of
Directors. Following these presentations, the Board of Directors of Weatherford,
with Mr. Lubar abstaining from voting, unanimously approved the merger pursuant
to the prior merger agreement and determined that the merger pursuant to the
prior merger agreement was in the interest of Weatherford. This approval was
subject to the finalization of the documentation relating to the proposed
transactions, the receipt of the Morgan Stanley opinion, satisfaction of certain
other conditions and approval of the final documentation for the proposed
transactions by the Weatherford Special Committee.
 
     From December 1, 1997, through December 12, 1997, the final terms of the
prior merger agreement were negotiated between Weatherford and Christiana.
 
   
     On or about December 11, 1997, C2 was formed for the purpose of acquiring
the two-thirds interest in TLC.
    
 
     On December 12, 1997, the Weatherford Special Committee approved the final
terms of the prior merger agreement and Morgan Stanley delivered its oral
opinion to the Weatherford Special Committee with respect to the prior merger
agreement, which was subsequently confirmed in writing.
 
   
     On December 12, 1997, the President of Christiana approved the final terms
of the prior merger agreement and Prudential Securities advised the President
that it was in a position to deliver its opinion to the effect that the
transaction was fair, from a financial point of view, to the shareholders of
Christiana. For the purposes of the Prudential Securities Opinion, the
transaction is defined as the merger, the TLC sale and the C2 offering.
    
 
   
     On December 15, 1997, we executed the prior merger agreement and TLC
purchase agreement.
    
 
   
     On April 9, 1998, Mr. Duroc-Danner advised Mr. Lubar that Weatherford would
be unable to consummate the merger until mid July 1998 because of an accounting
requirement that would not allow Weatherford to account for the merger of EVI,
Inc., the predecessor of Weatherford, with Weatherford Enterra, Inc. as a
"pooling of interests" if the merger were to close prior to Weatherford's
publication of 30 days of combined results with Weatherford Enterra, Inc. This
delay would have allowed both Christiana and Weatherford to terminate the prior
merger agreement after June 30, 1998. Messrs. Duroc-Danner and
    
 
                                       38
<PAGE>   42
 
   
Lubar agreed that it would be desirable to amend the prior merger agreement to
extend the termination date. In connection with such amendment, Christiana
requested that other modifications be made to the prior merger agreement and the
TLC purchase agreement to provide for the payment of the $10.0 million
contingent cash payment after four years, greater operational flexibility and
certain clarifying changes.
    
 
   
     On April 29, 1998, the Weatherford Special Committee considered the
requests by Christiana and approved an amendment to the prior merger agreement
and the TLC purchase agreement that:
    
 
   
     - Extended the termination date of the prior merger agreement to October
       31, 1998.
    
 
   
     - Allowed for the payment of the $10.0 million contingent cash payment on
       the earlier of:
    
 
   
        - The fifth anniversary of the closing of the merger.
    
 
   
        - The date that Christiana received consideration with a fair market
          value of $20.0 million or more in connection with a sale of its
          one-third interest in TLC.
    
 
   
     The inclusion of the early $10.0 million contingent cash payment provision
was agreed to in order to allow the Christiana shareholders to receive such
funds if Weatherford has received sufficient funds in respect of Christiana's
interest in TLC that is substantially in excess of the $10.0 million cash
required to be retained by Christiana after the merger. The amendment also
clarified certain provisions of the TLC purchase agreement, in particular
Christiana's "participation rights" in the event of a "change of control" of C2.
The principal change was that no "change in control" would be deemed to occur if
the Lubar family retains at least a 25% voting and ownership interest in C2 or
the resulting entity.
    
 
     On May 12, 1998, Mr. Donovan telephoned the Christiana directors to advise
them of the proposed amendment. On May 13, 1998, Mr. Donovan substantively
described in writing the proposed amendment to the Christiana Board of
Directors. Directors approving the amendment were requested to sign and return a
consent action. The directors unanimously approved the amendment, which approval
was effective on May 15, 1998.
 
   
     The amendment to the prior merger agreement and the TLC purchase agreement
was approved by the Weatherford Board of Directors upon the recommendation of
the Weatherford Special Committee by written consent, with Mr. Lubar executing
the consent only to comply with the requirements of Delaware law, but
effectively abstaining from voting. On May 25, 1998, the amendments to the prior
merger agreement and the TLC purchase agreement were executed.
    
 
   
     On or about July 17, 1998, we mailed to our respective stockholders proxy
materials to vote upon the approval of the prior merger agreement. Subsequent to
the mailing of those materials, the market price of the Weatherford common stock
declined below $30 per share, the price at which Christiana shareholders could
receive shares of Weatherford common stock in a tax free manner. The impact of
this decline was that the shares of Weatherford common stock that would have
been issued in the merger could no longer be received by the Christiana
shareholders in a tax free manner. During the first week of August,
representatives of Christiana and Weatherford discussed various possible
amendments to the prior merger agreement that would have allowed the Weatherford
shares to be received in a tax free manner. The alternatives that were discussed
included a purchase of Weatherford common stock by Christiana, a purchase of
Weatherford common stock by Weatherford and a corresponding adjustment to the
cash and stock components of the merger, a dividend or distribution by
Christiana of some or all of its cash to its shareholders and a combination of
the foregoing. In reviewing these alternatives, we determined that these
alternatives would require new approvals by our shareholders and that there was
not sufficient time to obtain these approvals prior to the shareholder meetings
of Weatherford and Christiana that were scheduled to be held on August 17, 1998.
    
 
     On August 7, 1998, the Board of Directors of Weatherford held a special
telephonic meeting to consider possible changes to the prior merger agreement to
allow the Weatherford shares to be received in a tax free manner. After
discussion of these matters and at the request of Christiana, no action was
taken by the Weatherford Board. The Weatherford and Christiana Boards also
determined that it would be in the best interest of their respective companies
to proceed with a vote of their stockholders on the prior
 
                                       39
<PAGE>   43
 
merger agreement and to monitor the market price of the Weatherford common stock
to see if the price of the Weatherford common stock would rise to above $29 per
share so as to allow the merger to be completed on its original terms.
 
     On August 17, 1998, the special meetings of the stockholders of Weatherford
and Christiana were held to consider and act upon the prior merger agreement. At
those meetings, the stockholders of Weatherford and Christiana overwhelmingly
approved the prior merger agreement with approximately 71% and 89% of the total
outstanding shares of Weatherford common stock and Christiana common stock,
respectively, voting in favor of the proposal. The percentage of Christiana
shares that voted in favor of the merger that were not held by the Lubar family
was approximately 98%.
 
   
     Following the approval of the prior merger agreement, we agreed to continue
to monitor the market price of the Weatherford common stock to see whether or
not the price of the Weatherford common stock would rise to above $29 per share
so as to allow the merger to be completed on its original terms.
    
 
   
     Given the overwhelming support of the Christiana shareholders in favor of
the merger, on or about September 11, 1998, Mr. Donovan met with Mr. Lubar to
explore modifications that would permit the transaction to close, but still on a
partially tax free basis. They agreed that any restructuring would have to have
a high degree of certainty that the transaction, as modified, would close. Mr.
Donovan and Mr. Lubar consulted with Christiana's legal counsel and accountants
concerning this matter. The alternatives considered by Messrs. Lubar and Donovan
were primarily focused on a purchase of shares of Weatherford common stock by
Christiana using Christiana's funds. They also considered the following:
    
 
   
     - An alternative that would have had Weatherford purchase its own shares
       prior to the merger with the cost of the purchase to be reduced from the
       cash consideration.
    
 
   
     - An alternative of a special dividend by Christiana.
    
 
   
They did not pursue the first alternative because of Weatherford's statements
that it would not agree to that type of transaction. They did not pursue the
second alternative because the special dividend would have been taxable to a
Christiana shareholder at ordinary income tax rates.
    
 
   
     After giving consideration to the impact on Christiana of not pursuing a
merger with Weatherford, Mr. Donovan determined that the transaction would still
be partially tax free if Christiana used its cash to purchase additional shares
of Weatherford common stock, for which Christiana shareholders would receive
newly issued Weatherford common stock on a one-for-one basis. Mr. Donovan
concluded that, if Christiana made such purchases, Weatherford might be willing
to eliminate the $10.0 million contingent cash component of the original merger
proposal. This would benefit Christiana shareholders because these funds would
no longer be subject to contingent claims and because Christiana shareholders
would have more control over when they were taxed. Cash is taxed when received,
but Weatherford common stock is not taxed until sold, which is in a
shareholder's discretion. Christiana also determined that if a portion of its
cash were to be utilized to purchase shares of Weatherford common stock, the use
of that cash would enhance the likelihood that the merger could be effected on a
partially tax free basis in that the common stock component of the consideration
to be paid in the merger would increase and the cash component would decrease.
Christiana concluded that if it were to acquire Weatherford common stock with
the $10.0 million cash that was to be retained by Weatherford pursuant to the
original merger proposal, then the merger could be consummated even if the
market price of the Weatherford common stock at closing was lower. Christiana
also determined that if it spent an additional $5.0 million to purchase
Weatherford common stock, the price of Weatherford common stock could be even
lower and the merger could still be consummated.
    
 
   
     Mr. Donovan and Mr. Lubar also concluded that the original reasons for the
merger as described in "Christiana's Reasons for the Merger" were still valid,
including, specifically, Christiana's interest in separating the large
Weatherford holdings from TLC and significantly increasing the marketability and
liquidity of the holdings of the Christiana shareholders.
    
 
     On September 17, 1998, Mr. Donovan presented this matter to the Christiana
Board. The Christiana Board considered three courses of action:
 
                                       40
<PAGE>   44
 
   
     - Continue the present course of monitoring Weatherford common stock, then
       close the existing transaction if the Weatherford common stock price rose
       to approximately $30 or higher per share.
    
 
   
     - Request that we mutually terminate the transaction.
    
 
   
     - Restructure the transaction in a way that would increase the assurance
       that the transaction could close at a lower per share Weatherford common
       stock price.
    
 
     Mr. Donovan described the modifications discussed with Mr. Lubar.
Considering that over 89% of the outstanding shares of Christiana common stock
were voted in favor of the merger, the advantages gained by the elimination of
the contingent cash consideration, that the original reasons for the transaction
were still valid and that there was increased assurance that the modified
transaction would close, the Christiana Board agreed that Weatherford should be
contacted regarding an amendment to the existing transaction on the terms
proposed by Messrs. Donovan and Lubar.
 
     On September 24, 1998, the Christiana Board appointed an independent
committee consisting of Messrs. Nicholas and Brady (the "Christiana Independent
Committee"). In approving the prior merger terms, the Christiana Board adopted
internal procedures to assure the procedural fairness of the merger in light of
the interest of Mr. Lubar and his family in the transaction. The Christiana
Board decided to appoint the Christiana Independent Committee to consider the
amended merger agreement because the Christiana Board concluded that the
appointment of the independent committee would more formally reflect the
internal procedures followed by the Christiana Board in approving the prior
terms. In so doing, the Christiana Board empowered the Christiana Independent
Committee with the authority to:
 
     - Review all aspects of the merger including any proposed amendment to the
       prior merger agreement.
 
     - Approve any amendments to the prior merger agreement and recommend such
       amendments to the full Christiana Board.
 
     - Have a telephonic meeting with Prudential Securities regarding the
       opinion of Prudential Securities as to the fairness of the transaction as
       amended.
 
     - Negotiate or oversee the negotiation of any amendments to the prior
       merger agreement.
 
     - Take such further action as necessary to amend the prior merger agreement
       consistent with interests of Christiana and its shareholders.
 
     The Christiana Independent Committee instructed Mr. Donovan to communicate
with Weatherford and then report to the Christiana Independent Committee.
 
     On September 18, 1998, Mr. Donovan contacted Curtis Huff, General Counsel
for Weatherford, regarding Christiana's position. Mr. Huff advised Mr. Donovan
that he would present the Christiana proposal to the Board of Directors of
Weatherford.
 
     On September 19, 1998, members of the Board of Directors of Weatherford
were contacted by management of Weatherford to discuss the general proposal by
Christiana.
 
     Because the composition of the Weatherford Board had changed since its
approval of the prior merger agreement and there remained only one member of the
Weatherford Special Committee (Robert Rayne), it was the consensus of the
Weatherford Board that approval of amendments to the prior merger agreement
should be approved by the full Board of Directors without the participation of
Mr. Lubar. Based on this conclusion, on September 21, 1998, Messrs. Duroc-Danner
and Huff met with Philip Burguieres and Robert Moses, two new independent
directors of Weatherford, to discuss with them in detail the historical terms
and rationale for the merger and the general terms of the new proposal by
Christiana.
 
     On September 22, 1998, the Weatherford Board of Directors met. At that
meeting, the Weatherford Board of Directors was provided a presentation on the
proposed amendments to the prior merger agreement. After discussion and review
of the proposal, the Weatherford Board of Directors, with Mr. Lubar not
participating in the vote, approved the amended merger agreement. The amended
merger agreement provided for the release of the $10.0 million holdback in
consideration for Christiana's
 
                                       41
<PAGE>   45
 
commitment to spend up to $15.0 million cash for the acquisition of Weatherford
common stock if necessary to allow for the merger to be consummated. The
Weatherford Board of Directors also required Christiana to commit to spend $10.0
million of the cash prior to the date of mailing of the Joint Proxy
Statement/Prospectus for such purchases regardless of the market price of the
Weatherford common stock. The Weatherford Board of Directors also conditioned
its approval on the receipt of another fairness opinion from Morgan Stanley to
the effect that the consideration to be paid pursuant to the amended merger
agreement is fair to Weatherford from a financial point of view. In approving
the amended merger agreement, the Weatherford Board gave particular weight to
the desire to obtain certainty for the consummation of the merger and agreed to
the release of the $10.0 million holdback in exchange for the greater certainty
provided by the commitment by Christiana to purchase additional shares of
Weatherford common stock.
 
     Following this meeting, representatives of Weatherford and Christiana
negotiated the final terms of the amended merger agreement.
 
   
     On October 12, 1998, Prudential Securities delivered to Christiana a new
opinion that the transaction was fair to the shareholders of Christiana from a
financial point of view. For the purposes of the Prudential Securities Opinion,
the transaction is defined as the merger, the TLC sale and the C2 offering.
    
 
     The Christiana Independent Committee met twice, on October 9 and 12, 1998,
to consider whether to recommend the amended merger agreement to the Christiana
Board. At the October 12, 1998 meeting, Prudential Securities met telephonically
with the Christiana Independent Committee to discuss in detail the analysis of
Prudential Securities and its opinion regarding the fairness of the transaction
to the Christiana shareholders from a financial point of view, which consisted
of a comparable transactions analysis, a transaction consideration analysis and
a stock trading history analysis, all of which are summarized below under
"Opinions of Financial Advisors -- Prudential Securities Opinion". On October
12, 1998, the Christiana Independent Committee considered such analysis and
opinion, along with the proposed terms of the amended merger agreement. At both
meetings, the Christiana Independent Committee concluded that the amended
transaction was fair from a financial point of view and in the best interests of
Christiana and all of its shareholders, including those shareholders who are
unaffiliated with the Lubar family. As a result on October 12, 1998, the
Christiana Independent Committee recommended the amendment to the full
Christiana Board.
 
   
     On October 12, 1998, the Christiana Board met to review the Christiana
Independent Committee's recommendations. The Board reviewed the proposed text of
the amended merger agreement and considered the opinion of Prudential
Securities. The Board specifically considered that, if Christiana made the
purchases of Weatherford common stock, the possibility existed that the stock
price could nevertheless decrease and, if it decreased below approximately $13
per share, the transaction would still not be able to close because it would be
a taxable transaction. Nevertheless, the Board considered that the proposed
amendment provided significant advantages to Christiana shareholders, namely,
the elimination of the $10.0 million holdback, an increased certainty that the
transaction would close because, without the amendment, the transaction would
not be able to close unless the Weatherford common stock price was $30.00 or
higher, which was deemed unlikely to occur before the October 31, 1998
termination date, and the advantages of being able to defer taxes on a higher
portion of the consideration. The Christiana Board, with Mr. Lubar abstaining
from voting, then approved the transaction.
    
 
     On October 12, 1998, Morgan Stanley delivered to Weatherford a new opinion
that the consideration to be paid by Weatherford pursuant to the merger
agreement was fair from a financial point of view to Weatherford.
 
   
     We executed the amended merger agreement on October 14, 1998.

                   WEATHERFORD'S REASONS FOR THE TRANSACTION
 
     The Board of Directors of Weatherford, with Mr. Lubar abstaining, has
approved the merger proposal and recommends that the stockholders of Weatherford
approve the merger proposal. The Weatherford Board of Directors believes that
the merger is in the interest of Weatherford and its stockholders for the
following reasons:
 
   
     -  The merger will provide Weatherford a one-third interest in TLC with a
        pro forma book value in excess of $7.0 million, and certain tax
        benefits, all without any consideration other than transaction costs and
        the exposure to certain contingent liabilities for which indemnity is
        being provided by C2 and TLC.
    
 
     -  The merger is expected to further improve the liquidity of the
        Weatherford common stock by placing the equivalent number of shares of
        Weatherford common stock that are held by Christiana directly in the
        hands of the Christiana shareholders.
 
   
The Weatherford Board of Directors believes that the transaction is beneficial
to Weatherford because of the favorable financial terms provided to Weatherford
for effecting the transaction. Except for the exposure to certain contingent
liabilities for which indemnity is being provided by C2 and TLC, the Board of
Directors of Weatherford does not believe that there exists any material
negative aspects of the transaction to the stockholders of Weatherford. Such a
transaction would not be available to Weatherford other than pursuant to the
terms of the merger.
    
 
   
     In considering the approval of the merger, the Weatherford Special
Committee and the Board of Directors of Weatherford noted that Weatherford,
through its ownership in Christiana, would be provided with an option to dispose
of Christiana's one-third interest in TLC five years from the date of the merger
for a cash consideration of $7.0 million. The Weatherford Special Committee and
Weatherford Board of Directors also noted that pursuant to the transaction,
Weatherford would be entitled to various tax benefits having a potential value
of up to approximately $600,000. The Weatherford Board of Directors also
specifically took into consideration the impact of the recent amendment to the
merger agreement on Weatherford and its stockholders. In particular, the Board
of Directors noted that the release of the $10.0 million cash holdback that
would have been available for payment of unpaid indemnification claims would no
longer be available to Weatherford. The Board of Directors, however, determined
the potential benefits to Weatherford of receiving a one-third interest in TLC
without providing any consideration other than the agreement to pursue the
transaction with Christiana outweighed the detriments to Weatherford of being
exposed to contingent liabilities for which there would not be a cash holdback.
The Board of Directors of Weatherford also considered the potential value of TLC
in the future and the benefit that a one-third interest in TLC would provide to
Weatherford.
    
 
   
     The Weatherford Special Committee and the Weatherford Board of Directors
also considered a number of other factors in approving the merger. Principal
among these additional factors was the fact that under the terms of the merger
agreement and the TLC purchase agreement, TLC and C2 are required to indemnify
Weatherford and Christiana for all current and historical fixed and contingent
liabilities relating to the businesses of Christiana, TLC and their respective
current and historical subsidiaries and predecessors. In addition, the Board of
Directors of Weatherford considered the fact that Christiana, C2 and Weatherford
would receive an opinion from American Appraisal to the effect that the
transaction would not render Christiana, TLC or C2 insolvent and that the value
of the assets of C2 and TLC would be sufficient to satisfy the liabilities of
Christiana, C2 and TLC after giving effect to the transaction. See "Opinions of
Financial Advisors -- American Appraisal Opinion". The Board of Directors of
Weatherford further considered the fact that another fairness opinion beyond the
date of the amended merger agreement would not be provided in the transaction
and that the other conditions to the closing of the transaction provided
appropriate protection to Weatherford for changes in circumstances between the
date of the opinion and the consummation of merger. The Weatherford Board of
Directors also placed considerable weight and reliance on the opinion of Arthur
Andersen LLP to the effect that the merger would be tax free to Weatherford and
Christiana and on the fact that even if the merger were subsequently found not
to be tax free, the merger would only be considered to be a taxable purchase of
    
 
                                       43
<PAGE>   47
 
   
stock of Christiana from the shareholders of Christiana and therefore would not
trigger any material tax liabilities to Weatherford or Christiana. The Board of
Directors of Weatherford also noted that, under the terms of the TLC purchase
agreement, TLC and C2 will be fully responsible for, and will indemnify
Christiana and Weatherford against, any and all tax liabilities that may arise
in connection with the merger. Finally, the Weatherford Special Committee and
the Weatherford Board of Directors considered the opinion of Morgan Stanley
dated October 9, 1998 that the consideration to be paid by Weatherford pursuant
to the amended merger agreement was fair from a financial point of view to
Weatherford.
    
 
     In approving the amended merger agreement, the Weatherford Board further
took into account the fact that the stockholders of Weatherford had approved the
prior merger agreement and that a substantial portion of the benefits that were
contemplated to be realized by the prior merger agreement would continue to be
realized by the amended merger agreement.
 
   
     Although no specific weight was given to any one of the above described
reasons or factors by the Weatherford Board in approving the merger, the ability
of Weatherford to acquire a one-third interest in TLC without any significant
cost to Weatherford other than transactional costs and with a complete indemnity
from TLC and C2 for prior liabilities of Christiana, TLC and their respective
current and historical subsidiaries and predecessors was considered to be the
most important factor by both the Weatherford Special Committee and the
Weatherford Board of Directors. The foregoing factors were all the material
factors considered by Weatherford's Board of Directors.
    
 
                    CHRISTIANA'S REASONS FOR THE TRANSACTION
 
   
     The Board of Directors of Christiana has approved the merger proposal and
recommends that the shareholders of Christiana approve the merger proposal. The
Christiana Board of Directors believes that the merger is in the interest of
Christiana and its shareholders. Christiana's Board of Directors has had for
some time a strategic interest to separate the company's large Weatherford
shareholdings from its operating business, TLC, in order to achieve a more
representative company valuation today and into the future. The Board has not
been interested in liquidating the Weatherford shareholdings given Christiana's
view as to the future potential for increase in the value of this asset and the
substantial corporate-level tax that would result from such a liquidation.
Various alternative transactions were considered in order to accomplish these
objectives, as described more fully under "Background of the Transaction". In
addition, as described under "Background of the Transaction", Weatherford had
advised Christiana that Weatherford was not interested in pursuing an
acquisition of Christiana if the transaction would be dilutive to Weatherford's
per share earnings or cash flow or would involve Weatherford's full ownership
and management of Christiana's warehousing and logistics business. Accordingly,
the Christiana Board of Directors did not believe an alternative transaction was
feasible. The proposed structure allows Christiana shareholders to exchange
their shares of Christiana common stock for newly issued shares of Weatherford
common stock in a tax efficient manner. Specifically, the Christiana Board noted
that the proposed structure would avoid the substantial corporate-level tax that
would result if Christiana sold the Weatherford shareholdings. This proposed
structure will give maximum flexibility to each Christiana shareholder to
determine whether retention of Weatherford shares is desirable.
    
 
   
     The Christiana Board of Directors also considered the advantages of a
separation of Christiana's two principal assets, its shares of Weatherford
common stock and TLC. These advantages include permitting Christiana
shareholders to make more focused investment decisions based on the specific
attributes of Weatherford and TLC. Specifically, a Christiana shareholder may,
after the merger, elect to:
    
 
   
     -  Retain the Weatherford share consideration and acquire stock in C2,
        thereby owning an interest in Weatherford and a warehousing and
        logistics business.
    
 
     -  Sell the Weatherford share consideration and acquire an interest in C2.
 
     -  Retain the Weatherford share consideration and not acquire an interest
        in C2.
 
                                       44
<PAGE>   48
 
   
     -  Sell the Weatherford share consideration and not acquire an interest in
        C2. Christiana's Board believes that the merger also will enable the
        financial markets to better understand and recognize the merits of TLC
        as a stand-alone entity.
    
 
   
Prior to the merger, investors interested in Christiana's warehousing and
logistics business could only participate in such business by purchasing
Christiana common stock, but a significant value of the Christiana common stock
was based upon its Weatherford shareholdings. After the merger, investors
interested in the logistics and warehousing business can acquire stock in C2,
whose only principal asset immediately after the merger will be its interest in
TLC.
    
 
   
     The Christiana Board concluded that the transaction would permit Christiana
shareholders to receive fair value for Christiana's Weatherford shareholdings.
Specifically, each shareholder would receive a pro rata portion of the
Weatherford shareholdings represented by each share of Christiana common stock.
The Christiana Board also concluded that the transaction would permit Christiana
shareholders to receive fair value for Christiana's ownership of TLC. C2 will
acquire a two-thirds interest in TLC. All Christiana shareholders will have the
same right to acquire his or her pro rata interest in TLC by subscribing for
shares in C2, so that a Christiana shareholder, if deemed desirable, could
continue to own an interest in TLC through C2. The reduction of direct ownership
right in TLC from 100% to 66.66% was fair to the Christiana shareholders in
light of the financial benefit to be realized by the Christiana shareholders in
receiving the Weatherford common stock in a tax free manner. The Christiana
Board believed that the value of the benefit of a tax free exchange more than
outweighed the loss of the one-third interest in TLC. They also noted that the
Christiana shareholders would benefit to a lesser extent in the one-third
interest in TLC through their ownership of Weatherford common stock.
    
 
     The Christiana Board has a long-standing familiarity with Weatherford, its
management and its operations, dating back to its ownership of Prideco, Inc.,
which Christiana sold to Weatherford in 1995. In reviewing the amended merger
agreement, the Christiana Board considered the recent declines in the
Weatherford common stock. In general, the Christiana Board viewed those declines
as being primarily associated with short-term market factors relating to the
pricing in the oil and gas industry. The Christiana Board felt that the stock
market declines in the Weatherford common stock were essentially the same as the
declines that other oilfield service companies were experiencing and were not
reflective of the long-term prospects of the industry in general and Weatherford
in particular. The Christiana Board reviewed various public information and
research reports regarding the industry and Weatherford and representatives of
Christiana met with representatives of Weatherford to discuss Weatherford's view
of the industry and its long-term prospects. Christiana believes that the
performance of Weatherford, which is one of the world's largest oilfield service
and equipment companies, should improve with a recovery in world oil prices.
Weatherford's views were similar to those of Christiana.
 
   
     Based on Christiana's review of the industry and Weatherford's prospects in
the industry, the Christiana Board concluded that an investment in Weatherford
was an attractive investment and a reasonable use of its funds, in particular if
a purchase by it of additional shares would allow for the merger to be
consummated. The Christiana Board did not consider a maximum price at which a
purchase of Weatherford common stock would not be beneficial because it believed
any price within the recent trading ranges would be desirable. The Christiana
Board also noted that the benefits of the tax free merger to Christiana
described below ceased to outweigh the potential cost of the loss of the future
benefit of a one-third interest in TLC at a Weatherford common stock price of
approximately $13.00 per share. As a result, the terms of the amended merger
agreement do not require Christiana to purchase additional shares of Weatherford
common stock at a price less than $13.00 per share.
    
 
     The Christiana Board also considered the substantial corporate-level tax
that would result from a sale of its Weatherford holdings. On August 14, 1997,
the date of the Christiana Board approval of the prior merger agreement,
Christiana's gain on the Weatherford holdings if it had sold such holdings would
have been approximately $165.0 million. A sale of such stock would have incurred
a corporate-level general income tax of approximately $57.8 million. Using the
market price of the Weatherford common stock as of October 12, 1998, the date of
the Christiana Board approval of the amended merger agreement,
 
                                       45
<PAGE>   49
 
Christiana's gain on a sale of its holdings of Weatherford common stock would
have been approximately $49.0 million. A sale of such stock would have incurred
a corporate-level general income tax of approximately $19.3 million. The
Christiana Board also noted that the cash consideration would be determined
based on the amount of cash of Christiana as of the effective time of the
merger, less Christiana's accrued unpaid taxes (without giving effect to the
value of certain tax deductions to be retained by Christiana) and fixed
liabilities not otherwise assumed by C2. In approving the amended merger
agreement, the Christiana Board took into consideration the beneficial and
detrimental aspects of the amendment. As for the beneficial aspects, the
Christiana Board noted that the amended merger agreement released the $10.0
million contingent cash holdback that was contemplated under the prior merger
agreement.
 
     The amended merger agreement also increases the tax free portion of the
consideration to be paid in the merger by increasing the number of shares of
Weatherford common stock to be issued in the merger and decreasing the cash
component to be paid in the merger. The increased tax free nature of the
transaction occurs by switching Weatherford common stock, which may be received
tax free, for a portion of the cash consideration, which will be taxable when
received. From a detrimental side, the Christiana Board noted that the amended
merger agreement would expose the Christiana shareholders to greater volatility
through the receipt of Weatherford common stock and that there would exist the
possibility that there could be a decline in the market price of the Weatherford
common stock from the date on which Christiana purchased the Weatherford common
stock as required by amended merger agreement and the time at which the shares
of Weatherford common stock are issued in the merger. Nevertheless, the
Christiana Board concluded that because of the release of the $10.0 million
holdback and because more of the consideration in the merger would be in the tax
free form of Weatherford common stock, the benefits of the merger more than
outweighed the detriment of the increased volatility associated with the
Weatherford common stock. The Christiana Board further noted that it believed
that the Weatherford common stock represented an attractive investment at its
current prices and that at the current prices it would present an opportunity
for gain in the future. The Christiana Board also noted that any Christiana
shareholder who desired to receive cash in lieu of the Weatherford common stock
would be able to do so merely by selling the shares of Weatherford common stock
received in the merger, following the merger. Finally, the Christiana Board gave
particular weight to the recommendation and approval of the amended merger
agreement by the Christiana Independent Committee.
 
     In approving the amended merger agreement, the Christiana Board took into
account the fact that the amended merger agreement contained a fixed formula for
determining the Weatherford share and cash consideration, but noted that the
stock and conversion ratios could change. The Christiana Board, however, did not
view the absence of a fixed exchange ratio as a detriment because the amended
merger agreement contains a mechanism for fixing the ratio that is solely
dependent on the assets of Christiana. As a result, the Christiana Board
considered the provisions fixing the exchange ratio as favorable to Christiana
in that it assured the Christiana shareholders with the right to realize the
entire benefit of its operations up to and through the closing. In addition,
because a substantial portion of Christiana's assets consist of Weatherford
common stock, the Christiana Board did not believe that changes in the market
price of the Weatherford common stock presented any material uncertainty or risk
to the Christiana shareholders that does not already exist.
 
   
     The Christiana Board also considered the costs to the shareholders in
connection with the merger, including, specifically, that the merger would
preclude other alternatives in the future and that Christiana (which following
the merger will be a wholly owned subsidiary of Weatherford) would retain a
one-third interest in TLC. The Christiana Board also considered potential
disadvantages of the transaction. The transaction would result in the increased
exposure of Christiana shareholders to fluctuations in the price of Weatherford
common stock. While an ownership of Christiana common stock provided balance
between Christiana's holdings in Weatherford and TLC, the merger would result in
Christiana shareholders owning Weatherford common stock directly, thereby
increasing reliance on the performance of Weatherford and on the oil and gas
industry and the level of domestic and international drilling activities
generally. Additionally, as part of and as an inducement to Weatherford to enter
into the merger, Weatherford
    
 
                                       46
<PAGE>   50
 
   
through Christiana would receive a one-third ownership interest in TLC for no
cash consideration. Christiana would have the ability to "put" this interest to
TLC for cash consideration of $7.0 million after five years from the date of the
merger. Christiana shareholders would benefit from this part of the transaction
only indirectly through their ownership of approximately 4.5% of outstanding
Weatherford common stock received in connection with the merger. Otherwise,
Christiana shareholders will receive no direct benefit from this aspect of the
transaction. The Christiana Board nevertheless considered that the advantages
outweighed such disadvantages.
    
 
   
     In considering the approval of the merger pursuant to the amended merger
agreement, the Christiana Board of Directors considered the opinion of
Prudential Securities that the transaction is fair to Christiana shareholders
from a financial point of view. For the purposes of the Prudential Securities
Opinion, the transaction is defined as the merger, the TLC sale and the C2
offering. The Prudential Securities Opinion will not be updated beyond the date
of the amended merger agreement or as of the closing of the transaction. The
Christiana Board believed that receipt of the Prudential Securities Opinion
prior to the execution of the amended merger agreement was sufficient for its
approval of the transaction. The Christiana Board understood that a change in
circumstances between the date of the Prudential Securities Opinion and the
consummation of the transaction could impact the fairness of the transaction,
but the Christiana Board believed that the protections afforded in the amended
merger agreement and its familiarity with Weatherford rendered an update of the
Prudential Securities Opinion unnecessary.
    
 
     The Christiana Board of Directors also placed considerable weight and
reliance on the opinion of Arthur Andersen LLP to the effect that the merger
would be tax free to Weatherford and Christiana.
 
     The Christiana Board of Directors also considered the potential adverse
implications of continuing to be subject to the costly regulatory requirements
relating to Christiana's status as a public company. Total expenses associated
with Christiana being a public company in fiscal 1998 were approximately
$150,000. A Christiana shareholder interested in Weatherford could, after the
merger, hold its interest in Weatherford directly without having to hold its
interest in one public entity, Christiana, which in turn held a significant
interest in another public entity, Weatherford.
 
   
     Although the pro forma book value of TLC was approximately $22.8 million at
December 31, 1997 and $23.4 million at September 30, 1998, the Christiana Board
believes that the sale of a two-thirds interest in TLC to C2 for approximately
$10.67 million is fair to Christiana shareholders, based on the following:
    
 
   
     - Christiana's view as to the value of such interest after giving effect to
      restrictions and obligations applicable to TLC and C2 after the sale and
      on the opinion of Prudential Securities that the transaction (which for
      purposes of the Prudential Securities Opinion is defined as the merger,
      the TLC sale and the C2 offering) was fair from a financial point of view
      to Christiana shareholders.
    
 
   
     - The fact that any Christiana shareholder who wishes to retain an interest
       in TLC may do so by electing to purchase his or her pro rata portion of
       C2 common stock at a price of $4.00 per share, the same price offered to
       all Christiana shareholders including the Lubar family and all directors
       and officers of Christiana.
    
 
     The Christiana Board acknowledged that the value of Weatherford
shareholdings for Christiana was the major determinant in Christiana's share
price in the market. Hence, if Weatherford's share price increased, Christiana's
share price increased too. Accordingly, if Weatherford's share price declined,
Christiana's share price declined as well. Christiana's Board, however, did not
and does not control Weatherford and for this reason decided that it was better
to manage operations that it could control, rather than have the Christiana
stock price dependent upon an entity (Weatherford) that it did not control. The
Christiana Board did not favor selling its shares of Weatherford common stock,
but rather wanted to provide the investment decision directly to the Christiana
shareholders through the merger.
 
     As previously stated, the price to be paid by the purchasing entity,
ultimately determined to be C2, was determined unilaterally by Mr. Lubar in
connection with his negotiations with Weatherford. The Christiana Board believes
this to be procedurally fair for the following reasons. First, Mr. Lubar did not
 
                                       47
<PAGE>   51
 
   
think it appropriate to pay more than $10.67 million for the two-thirds interest
in TLC, because TLC, at the insistence of Weatherford, would be assuming
significant liabilities. TLC, at Weatherford's insistence, would also be
required to restrict its operational activities, in order to assure, to
Weatherford's satisfaction, that TLC would be able to satisfy its obligations.
Finally, the Christiana Board concluded that if a Christiana shareholder
concurred that the price was appropriate, the Christiana shareholder could
continue his indirect ownership in TLC by acquiring stock in C2, along with the
Lubar family. If the Christiana shareholder concluded that the price was too
low, the Christiana shareholder could vote against the merger and elect
dissenters' rights. If the Christiana shareholder concluded that the price for
TLC was too high, the Christiana shareholder could vote in favor of the merger
and not elect to purchase stock in C2.
    
 
   
     The Christiana Board believes it to be fair for C2 to pay $10.67 million
for a two-thirds interest in TLC and C2 to pay Weatherford $7.0 million for its
one-third interest, if Weatherford elects to put its interest in TLC at such
price, because of the difference in the time value of money. The $10.67 million
for the two-thirds interest in TLC will be paid to the Christiana shareholders
at the closing of the merger, whereas Weatherford will not receive its $7.0
million until it exercises its put, which will not be for at least five years.
The Christiana Board determined the $7.0 million put value by allocating $5.34
million to a one-third interest in TLC, which is consistent with selling a
two-thirds interest for $10.67 million, and then increasing such amount by a
modest compound rate of return on such amount of approximately 5 1/2% for five
years, resulting in a put price of $7.0 million.
    
 
   
     The Christiana Board noted that the price of the Christiana common stock
immediately prior to the execution of the amended merger agreement was $16 3/8
and recognized that, depending upon the price of Weatherford common stock at the
closing of the merger relative to the price of the Christiana common stock at
such time, the consideration to be received could be less than the then current
market price of the Christiana common stock. The Board considered whether to
recommend the merger, even though the total consideration could be less than the
current market price of Christiana common stock. Christiana currently estimates
that the Weatherford share consideration will be .85191 of a share of
Weatherford common stock, and the cash consideration will be between $3.50 and
$4.00, for each share of Christiana common stock. If Christiana is required to
make additional purchases of Weatherford common stock of $5.0 million,
Christiana estimates that the cash consideration will be between $2.50 and $3.00
per share of Christiana common stock. The Christiana Board noted the significant
appreciation in the Weatherford common stock at the time it approved the merger
in August 1997 and, based upon its assessment of favorable long-term
appreciation of the Weatherford common stock, felt it advisable that each
Christiana shareholder have the opportunity to decide whether such stock should
be held or sold. As long as Christiana held the Weatherford common stock, the
Christiana shareholders could not individually make such a decision.
Consequently, even though it was possible that the total consideration to be
received by the Christiana shareholders was less than the current price of the
Christiana common stock, the Christiana Board determined that the merger was in
the best interest of all of its shareholders.
    
 
     Christiana recognized that costs would be incurred to establish C2. While
such costs will not be paid by Christiana, they will be paid by C2 from funds
raised in connection with C2's public offering. The costs incurred in connection
with establishing C2 are expected to be as follows: legal fees and expenses
($140,000), accounting and tax services ($75,000), filing fees with the
Commission ($6,140), printing costs, expenses for state securities laws filings
and transfer agent fees and expenses ($36,000), Nasdaq listing fee ($10,000) and
miscellaneous ($8,000).
 
   
     Christiana common stock traded at $40 3/4 immediately prior to the
execution of the prior merger agreement and traded at $16 3/8 immediately prior
to the execution of the amended merger agreement. On the day of the announcement
and execution of the amended merger agreement, the price closed at $17 3/8, but
as of December 22, 1998, it closed at $18 3/8. The Christiana Board does not
consider the decline in its stock price to be relevant for two reasons. First,
the Weatherford common stock held by Christiana is a significant Christiana
asset, so Christiana's stock price is substantially dependent on the Weatherford
common stock price. Second, the Christiana Board believes it important that each
Christiana shareholder make an independent decision to retain or sell the
Weatherford common stock. Such independent decision can only be made if the
Weatherford common stock is distributed to Christiana shareholders.
    
 
                                       48
<PAGE>   52
 
Consequently, even if the total consideration to be received by Christiana
shareholders is less than its price prior to the merger, the Christiana Board
considers the transaction still to be in the best interest of all Christiana
shareholders.
 
   
     The Christiana Board (including Mr. Lubar) and the board of directors and
management of C2 believe the transaction is fair to the unaffiliated
shareholders of Christiana. In arriving at this conclusion, these entities
considered the structure of the transaction and how such structure rendered
immaterial traditional valuation analysis such as current and historical market
prices, net book value, going concern value, liquidation value and discounted
cash flow value. While the Christiana Board took into account its view of the
value of TLC and Christiana in approving the transaction, the Christiana Board
believed that the benefits to be derived from the transaction combined with the
right of the Christiana shareholders to participate in TLC through Weatherford
and C2 rendered in their view the need to perform traditional valuation analyses
immaterial. In this regard, the Christiana Board noted that Christiana had two
principal assets, its holdings in Weatherford common stock and its ownership of
TLC. The transaction essentially results in each Christiana shareholder
receiving his or her pro rata share of Weatherford common stock held by
Christiana on a tax free basis and a right to purchase such Christiana
shareholder's pro rata interest in C2, the entity that will acquire a two-thirds
interest in TLC as part of the transaction. Finally, the cost to Christiana in
allowing Weatherford to receive a one-third interest in TLC in the transaction
was more than offset by the expected economic benefits to be realized by
Christiana in the transaction.
    
 
   
     The Christiana Board also considered the fact that each unaffiliated
shareholder of Christiana will be able to participate in the purchase of TLC
through C2 on the same basis as Mr. Lubar and all other affiliates of
Christiana. The Christiana Board of Directors believes that treating
unaffiliated shareholders of Christiana in a similar way to Mr. Lubar supports
the fairness of the consideration to the unaffiliated shareholders in that it
provides the unaffiliated shareholders with the same rights as any affiliated
shareholder, including family members of Mr. Lubar.
    
 
     In connection with the consideration of the amended merger agreement, the
Christiana Board of Directors appointed a special committee consisting of
Messrs. Nicholas and Brady and authorized the Christiana Independent Committee
to have the power to consider and approve the amended merger agreement. The
Christiana Independent Committee reviewed the terms of the amended merger
agreement and concurred with the various reasons for pursuing the merger as
described above. The Christiana Independent Committee also concluded that the
terms of the merger were in the best interest of Christiana and its shareholders
and recommended approval of the amended merger agreement by the full Christiana
Board. The Christiana Board of Directors, with Mr. Lubar abstaining, approved
the amended merger agreement on October 12, 1998.
 
   
     The merger has been structured to require approval of at least 80% of the
votes entitled to be cast at the Christiana special meeting and two-thirds of
the votes entitled to be cast at the Christiana special meeting other than the
Lubar Shares, which are shares beneficially owned by the Lubar family, both as a
result of a desire by the Christiana Board to assure fairness and as required by
Wisconsin law. Because of this supermajority voting requirement, the Christiana
Board did not believe that a separate vote of a majority of the unaffiliated
shareholders of Christiana would be necessary to insure fairness.
    
 
     Although no specific weight was given to any one of the above-described
reasons or factors by the Christiana Board in approving the merger, the
placement of the Weatherford common stock currently held by Christiana directly
in the hands of the Christiana shareholders, thereby giving each shareholder
maximum flexibility with regard to such shares without any significant cost, was
considered to be the most important factor by the Christiana Board of Directors.
The foregoing factors were all the material factors considered by Christiana's
Board of Directors.

                         OPINIONS OF FINANCIAL ADVISORS
 
MORGAN STANLEY OPINION
 
     In a letter agreement effective November 7, 1997 (the "Engagement Letter"),
Weatherford engaged Morgan Stanley to provide a financial fairness opinion in
connection with the merger. Morgan Stanley was selected by the Weatherford Board
of Directors to provide this financial fairness opinion based on Morgan
Stanley's qualifications, expertise and reputation, as well as Morgan Stanley's
investment banking relationship and familiarity with Weatherford. On December
15, 1997, Morgan Stanley delivered to the Weatherford Board of Directors an
opinion to the effect that, on and as of the date of such opinion, and based on
assumptions made, matters considered and limits of review, as set forth in such
opinion, the consideration to be paid by Weatherford pursuant to the prior
merger agreement was fair from a financial point of view to Weatherford.
Subsequent to the delivery of Morgan Stanley's opinion, however, the prior
merger agreement and certain related documents were further amended.
Consequently, Morgan Stanley delivered to the Weatherford Board of Directors an
updated written opinion dated October 9, 1998 (the "Morgan Stanley Opinion") to
the effect that, on and as of the date of the Morgan Stanley Opinion, and based
upon assumptions made, matters considered and limits of review, as set forth in
such opinion, the consideration to be paid by Weatherford pursuant to the
amended merger agreement was fair from a financial point of view to Weatherford.
 
     The full text of the Morgan Stanley Opinion, dated October 9, 1998, which
sets forth, among other things, assumptions made, procedures followed, matters
considered and limitations on the review undertaken by Morgan Stanley in
rendering its opinion, is attached as Appendix D to this Joint Proxy
Statement/Prospectus and incorporated herein by reference. Weatherford
stockholders are urged to, and should, read the Morgan Stanley Opinion carefully
and in its entirety. The Morgan Stanley Opinion is directed to the Weatherford
Board of Directors, addresses only the fairness of the consideration to be paid
by Weatherford pursuant to the amended merger agreement from a financial point
of view to Weatherford and does not address any other aspect of the merger or
constitute a recommendation to any holder of Weatherford common stock as to how
to vote at the Weatherford special meeting. The following summary of the Morgan
Stanley Opinion is qualified in its entirety by reference to the full text of
the Morgan Stanley Opinion attached as Appendix D to this Joint Proxy
Statement/Prospectus. Morgan Stanley has consented to the use of the Morgan
Stanley Opinion as an appendix to this Joint Proxy Statement/ Prospectus.
 
     In rendering the Morgan Stanley Opinion, Morgan Stanley, among other
things:
 
     - Reviewed certain publicly available financial statements and other
       information of Weatherford and Christiana.
 
   
     - Reviewed certain internal financial statements and other financial and
       operating data concerning Weatherford, Christiana and TLC prepared by the
       managements of Weatherford, Christiana and TLC, respectively.
    
 
   
     - Analyzed certain financial projections concerning Weatherford, Christiana
       and TLC prepared by the managements of Weatherford, Christiana and TLC,
       respectively.
    
 
   
     - Discussed the past and current operations and financial condition and the
       prospects of Weatherford, Christiana and TLC with senior executives of
       Weatherford, Christiana and TLC, respectively.
    
 
     - Analyzed the pro forma impact of the merger on Weatherford's earnings per
       share.
 
     - Reviewed the reported prices and trading activity for the Weatherford
       common stock and Christiana common stock.
 
   
     - Reviewed the amended merger agreement, the TLC purchase agreement and
       certain related documents.
    
 
                                       50
<PAGE>   54
 
     - Reviewed a draft letter dated as of October 7, 1998 substantially similar
       to the letter to be provided to the Boards of Directors of Weatherford
       and Christiana by Arthur Andersen LLP, regarding the tax treatment of the
       merger.
 
     - Discussed and reviewed with Weatherford and Fulbright & Jaworski L.L.P.
       the results of their legal and environmental due diligence.
 
     - Performed such other analyses and considered such other factors as Morgan
       Stanley deemed appropriate.
 
   
     In rendering the Morgan Stanley Opinion, Morgan Stanley assumed and relied
upon, without independent verification, the accuracy and completeness of the
information reviewed by it for the purposes of the Morgan Stanley Opinion. With
respect to the financial projections, Morgan Stanley assumed that they were
reasonably prepared on bases reflecting the best currently available estimates
and judgments of the future financial performances of Weatherford, Christiana
and TLC. Morgan Stanley did not make any independent valuation or appraisal of
the assets or liabilities of Weatherford, Christiana or TLC, except that Morgan
Stanley received the draft letter of Arthur Andersen LLP referred to above and
the verbal report concerning certain legal and environmental due diligence
analyses performed by Weatherford and Fulbright & Jaworski L.L.P. referred to
above, and Morgan Stanley relied, without independent verification, upon such
items for purposes of the Morgan Stanley Opinion. In addition, Morgan Stanley
has assumed the TLC sale will be consummated prior to or simultaneously with the
merger in accordance with the terms set forth in the TLC purchase agreement,
including any terms and conditions relating to indemnification, and that the
merger will be consummated in accordance with the terms set forth in the amended
merger agreement, including that all material conditions to closing have been
satisfied and not waived. Morgan Stanley also has assumed that the merger shall
qualify as a reorganization within the meaning of Section 368(a) of the Code. In
arriving at the Morgan Stanley Opinion, Morgan Stanley was not authorized to
consider, and did not consider, any alternative transaction or transaction
structure. The Morgan Stanley Opinion was necessarily based on economic, market
and other conditions as in effect on, and the information made available to
Morgan Stanley as of, the date thereof.
    
 
     The following is a brief summary of certain analyses performed by Morgan
Stanley in preparation of the Morgan Stanley Opinion:
 
   
     Discounted Cash Flow Analysis. Morgan Stanley analyzed certain financial
projections prepared by the management of TLC for the fiscal years 1999 through
2003 (the "Projections") and performed a discounted cash flow analysis of TLC
based on the Projections. Morgan Stanley discounted the unlevered free cash
flows of TLC at a range of discount rates of 10.0% to 12.0%, representing an
estimated weighted average cost of capital range for TLC, and terminal values
based on a range of multiples of 5 to 7 times estimated 2003 earnings before
interest, taxes, depreciation and amortization ("EBITDA") to arrive at a range
of present values for TLC. Such present values were then adjusted for TLC's
debt, net of cash, all pro forma for the TLC sale as of June 30, 1998, to arrive
at a net asset value. Based on this analysis, Morgan Stanley calculated values
representing one-third of TLC's equity value ranging from approximately $9.4
million to $18.6 million.
    
 
   
     Morgan Stanley also performed certain sensitivity analyses on the
Projections (the "Adjusted Projections"). Specifically, Morgan Stanley assumed
that TLC projected sales revenue from 1999 through 2003, with the exception of
sales revenue related to government contracts, remained the same as actual 1998
sales revenue. Morgan Stanley also assumed that TLC's gross margin from 1999
through 2003 remained the same as actual 1998 gross margin. The Adjusted
Projections assume that TLC would have more long-term debt in 2003 than the
Projections show. Morgan Stanley performed a discounted cash flow analysis of
TLC based on the Adjusted Projections. Morgan Stanley discounted the unlevered
free cash flows of TLC at a range of discount rates of 10.0% to 12.0%,
representing an estimated weighted average cost of capital range for TLC, and
terminal values based on a range of multiples of 5 to 7 times estimated 2003
EBITDA to arrive at a range of present values for TLC. Such present values were
then adjusted for TLC's debt, net of cash, all pro forma for the TLC sale as of
June 30, 1998, to arrive at a net asset value.
    
 
                                       51
<PAGE>   55
 
   
Based on this analysis, Morgan Stanley calculated values representing one-third
of TLC's equity value ranging from approximately $1.2 million to $7.2 million.
    
 
   
     Projected Credit Statistics Analysis. Based on the Projections, Morgan
Stanley calculated financial ratios including EBITDA/Interest, (EBITDA-Capital
Expenditures)/Interest and Total Debt/EBITDA (collectively, the "Ratios") for
every year from 1999 through 2003. Morgan Stanley calculated a range for
EBITDA/Interest of 3.3 times in fiscal 1999 to 7.3 times in fiscal 2003, a range
for (EBITDA-Capital Expenditures)/Interest of 2.4 times in fiscal 1999 to 5.3
times in fiscal 2003 and, a range for Total Debt/ EBITDA of 3.4 times in fiscal
1999 to 1.4 times in fiscal 2003. Morgan Stanley also calculated the Ratios
assuming that TLC borrows an additional $7.0 million in 2003 in order to meet
its obligation pursuant to the purchase obligation of TLC of Christiana's
one-third interest in TLC under the TLC purchase agreement. Based on this
assumption, Morgan Stanley calculated values for EBITDA/Interest of 6.5 times,
(EBITDA-Capital Expenditures)/Interest of 4.8 times and Total Debt/EBITDA of 1.9
times, all in fiscal 2003.
    
 
   
     Based on the Adjusted Projections, Morgan Stanley calculated a range for
EBITDA/Interest of 2.6 times in fiscal 1999 to 3.6 times in fiscal 2003, a range
for (EBITDA-Capital Expenditures)/Interest of 1.7 times in fiscal 1999 to 2.4
times in fiscal 2003 and, a range for Total Debt/EBITDA of 4.3 times in fiscal
1999 to 3.1 times in fiscal 2003. Morgan Stanley also calculated the Ratios
assuming that TLC borrows an additional $7.0 million in 2003 in order to meet
its obligation pursuant to the purchase obligation of TLC of Christiana's
one-third interest in TLC under the TLC purchase agreement. Based on this
assumption, Morgan Stanley calculated values for EBITDA/Interest of 3.3 times,
(EBITDA-Capital Expenditures)/Interest of 2.2 times and Total Debt/EBITDA of 3.8
times, all in fiscal 2003.
    
 
   
     Selected Precedent TLC/Warehousing Acquisitions Analysis. Using publicly
available information, Morgan Stanley reviewed recent precedent transactions
involving companies which provide services comparable to those of TLC such as
refrigerated warehousing, logistic services and transportation. The companies
which were selected for inclusion in Morgan Stanley's analysis provide services
which Morgan Stanley believes are comparable to those provided by TLC.
    
 
   
     Morgan Stanley analyzed the purchase prices and implied transaction
multiples paid in the following publicly announced logistic/warehousing
transactions: the acquisition of Heijden Logistics and France Distribution
System from Mayne Nickless Limited by Hayes plc, the acquisition of Caliber
System, Inc. by Federal Express Corporation, the acquisition of AmeriCold
Corporation and URS Logistics, Inc. by JV -- Vornado Realty Trust and Crescent
Real Estate Equities Company, and the acquisition of Intertrans Corporation by
Fritz Companies, Inc. (collectively, the "Precedent Transactions"). Morgan
Stanley reviewed publicly available financial information including the
aggregate value to latest twelve month ("LTM") EBITDA. Morgan Stanley observed
an aggregate value to LTM EBITDA range of 6.4 to 14.0 times for the Precedent
Transactions.
    
 
     Pro Forma Analysis of the Merger. Morgan Stanley analyzed the pro forma
impact of the merger on Weatherford's earnings per share for the fiscal years
1999 and 2000. Such analysis was based on earnings projections for Weatherford
prepared by the management of Weatherford and on the Projections. Morgan Stanley
noted that the merger would be slightly accretive to Weatherford shareholders in
1999 and in 2000.
 
     In connection with the review of the merger by the Weatherford Board of
Directors, Morgan Stanley performed a variety of financial and comparative
analyses for purposes of the Morgan Stanley Opinion given in connection
herewith. While the foregoing summary describes the analyses and factors
reviewed by Morgan Stanley in connection with the Morgan Stanley Opinion, it
does not purport to be a complete description of all the analyses performed by
Morgan Stanley in arriving at its opinion. The preparation of a fairness opinion
is a complex process and is not necessarily susceptible to partial analysis or
summary description. In arriving at the Morgan Stanley Opinion, Morgan Stanley
considered the results of all of its analyses as a whole and did not attribute
any particular weight to any analysis or factor considered by it. Furthermore,
selecting any portion of its analyses, without considering all analyses, would
create an incomplete view of the process underlying the Morgan Stanley Opinion.
In addition, Morgan Stanley may
 
                                       52
<PAGE>   56
 
   
have given various analyses and factors more or less weight than other analyses
or factors, and may have deemed various assumptions more or less probable than
other assumptions, so that the ranges of valuations resulting from any
particular analysis described above should not be taken to be Morgan Stanley's
view of the actual value of Christiana or TLC. In performing its analyses,
Morgan Stanley made numerous assumptions with respect to industry performance,
general business and economic conditions and other matters, many of which are
beyond the control of Weatherford, Christiana or TLC. Any estimates contained
herein are not necessarily indicative of future results or actual values, which
may be significantly more or less favorable than those suggested by such
estimates. The analyses performed were prepared solely as part of Morgan
Stanley's analysis of the fairness of the consideration to be paid by
Weatherford pursuant to the amended merger agreement from a financial point of
view to Weatherford and were conducted in connection with the delivery of the
Morgan Stanley Opinion. The analyses do not purport to be appraisals or to
reflect the prices at which Christiana or TLC might actually be sold. Morgan
Stanley did not recommend the consideration to be paid by Weatherford or that
any consideration to be paid by Weatherford constituted the only appropriate
consideration for the merger.
    
 
     In addition, Morgan Stanley's opinion to the Weatherford Board of Directors
and the Weatherford Special Committee was one of the many factors taken into
consideration by the Weatherford Board of Directors and the Weatherford Special
Committee in making their determination to recommend approval of the merger.
Consequently, the Morgan Stanley analyses described above should not be viewed
as determinative of the opinion of the Weatherford Board of Directors and the
Weatherford Special Committee with respect to the consideration to be paid in
connection with the merger. The consideration to be paid by Weatherford pursuant
to the amended merger agreement was determined through arm's-length negotiations
between Weatherford and Christiana and was approved by the Weatherford Board of
Directors.
 
     Weatherford engaged Morgan Stanley to provide the Morgan Stanley Opinion
because of its experience and expertise. Morgan Stanley is an internationally
recognized investment banking and advisory firm. Morgan Stanley, as part of its
investment banking business, is regularly engaged in the valuation of businesses
and their securities in connection with mergers and acquisitions, negotiated
underwritings, competitive biddings, secondary distributions of listed and
unlisted securities, private placements and valuations for corporate and other
purposes. In the course of its market-making and other trading activities,
Morgan Stanley may, from time to time, have a long or short position in, and buy
and sell, securities of, Weatherford or Christiana. In the past, Morgan Stanley
and its affiliates have provided financial advisory services to Weatherford and
have received customary fees in connection with these services.
 
     Weatherford has paid Morgan Stanley a fee of $250,000 in connection with
the delivery of the Morgan Stanley Opinion. In addition, Weatherford has agreed
to indemnify Morgan Stanley and its affiliates, their respective directors,
officers, agents and employees and each person, if any, controlling Morgan
Stanley or any of its affiliates against certain liabilities and expenses,
including liabilities under federal securities laws, in connection with Morgan
Stanley's engagement.
 
     Morgan Stanley has provided investment banking services for Weatherford in
the past, including serving as joint lead manager in Weatherford's private
placement of its 5% Convertible Subordinated Preferred Equivalent Debentures due
2027 (the "Debentures"), and may provide such services in the future. In
addition, Prudential Securities has provided investment banking services to
Weatherford in the past, including serving as a co-manager of Weatherford's
private placement of the Debentures, and may provide such services in the
future.
 
PRUDENTIAL SECURITIES OPINION
 
   
     On October 12, 1998, Prudential Securities delivered the Prudential
Securities Opinion to the Christiana Independent Committee and the Christiana
Board to the effect that, as of such date, the transaction was fair, from a
financial point of view, to the shareholders of Christiana. For the purposes of
the Prudential Securities Opinion, the transaction is defined as the merger, the
TLC sale and the C2
    
 
                                       53
<PAGE>   57
 
   
offering. In requesting the Prudential Securities Opinion, the Christiana
Independent Committee and the Christiana Board did not give any special
instructions to Prudential Securities or impose any limitation upon the scope of
the investigation that Prudential Securities deemed necessary to enable it to
deliver its opinion.
    
 
   
     The full text of the Prudential Securities Opinion, which sets forth the
assumptions made, the matters considered and the limitations on the review
undertaken, is set forth as Appendix E to this joint proxy statement/prospectus
and is incorporated herein by reference and should be read in its entirety in
connection with this Joint Proxy Statement/Prospectus. The Prudential Securities
Opinion is directed only to the fairness of the transaction to the shareholders
of Christiana from a financial point of view and does not address any other
terms of the transaction or the Christiana Board of Directors' underlying
business decision to effect the transaction. The Prudential Securities Opinion
was delivered for the information of Christiana's Board and the Christiana
Independent Committee and does not constitute a recommendation to any
shareholder of Christiana as to how such shareholder should vote such
shareholder's shares at the Christiana special meeting. The summary of the
Prudential Securities Opinion set forth in this joint proxy statement/prospectus
is qualified in its entirety by reference to the full text of the Prudential
Securities Opinion attached as Appendix E. Prudential Securities has consented
to the use of the Prudential Securities Opinion as an appendix to this joint
proxy statement/prospectus.
    
 
     In conducting its analysis and arriving at its opinion dated October 12,
1998, Prudential Securities reviewed such information and considered such
financial data and other factors as Prudential Securities deemed relevant under
the circumstances, including, among others, the following:
 
   
     - The Lubar/C2 agreement, the TLC purchase agreement, a draft dated October
       10, 1998 of the amended merger agreement and a draft dated October 10,
       1998 of Amendment No. 2 to the TLC purchase agreement ("Amendment No.
       2").
    
 
     - Certain publicly available historical financial and operating data
       concerning Christiana, including, but not limited to, (a) the Annual
       Report to Shareholders and Annual Report on Form 10-K for the fiscal year
       ended June 30, 1998, and (b) the Joint Proxy Statement/Prospectus for the
       special meeting of Christiana shareholders held on August 17, 1998; and
       certain pro forma financial data prepared by Christiana management.
 
     - Certain publicly available historical financial and operating data for
       Weatherford including, but not limited to, (a) the Annual Report on Form
       10-K for the fiscal year ended December 31, 1997, (b) the Quarterly
       Report on Form 10-Q for the quarter ended June 30, 1998, (c) the Current
       Report on Form 8-K dated March 4, 1998, and (d) the Joint Proxy
       Statement/Prospectus for the special meeting of Weatherford stockholders
       held on August 17, 1998.
 
   
     - Certain information relating to TLC, including historical financial data
       for the fiscal years ended June 30, 1993 through June 30, 1998, provided
       by the management of TLC.
    
 
   
     - Certain information relating to TLC, including financial forecasts for
       the fiscal years ending June 30, 1999 through June 30, 2002, prepared by
       the management of TLC.
    
 
     - The financial terms of certain recent transactions Prudential Securities
       deemed relevant to Prudential Securities' inquiry.
 
     - The historical stock prices and trading volumes of Christiana common
       stock and Weatherford common stock.
 
     - Such other financial studies, analyses and investigations that Prudential
       Securities deemed appropriate.
 
Prudential Securities assumed, with Christiana's consent, that the draft of the
amended merger agreement and the draft of Amendment No. 2 that Prudential
Securities reviewed (both, as referred to above) will
 
                                       54
<PAGE>   58
 
   
conform in all material respects to the definitive form of the amended merger
agreement and Amendment No. 2. Prudential Securities met with the senior
management of Christiana and TLC to discuss:
    
 
     - The prospects for Christiana's business.
 
     - Their estimates of the future financial performance of Christiana.
 
     - The financial impact of the merger on Christiana.
 
   
     - Such other matters that Prudential Securities deemed relevant. Prudential
       Securities also visited selected Christiana and TLC facilities.
    
 
   
     In connection with its review and analysis and in arriving at its opinion,
Prudential Securities assumed and relied upon the accuracy and completeness of
the financial and other information provided to it by Christiana and TLC and did
not undertake any independent verification of such information or any
independent valuation or appraisal of any of the assets or liabilities of
Christiana or TLC. With respect to the financial forecasts provided to
Prudential Securities by Christiana for Christiana and by TLC for TLC,
Prudential Securities assumed that such forecasts (and the assumptions and bases
therefor) were reasonably prepared and represent the respective management's
best currently available estimate as to the future financial performance of
Christiana and TLC. In addition, the Prudential Securities Opinion assumes that:
    
 
   
     - The merger will qualify as a reorganization within the meaning of Section
368(a) of the Code.
    
 
   
     - Neither Christiana nor Sub will recognize any gain or loss for federal
      income tax purposes as a result of the receipt by Weatherford of
      Christiana common stock in exchange for Weatherford common stock in the
      merger.
    
 
   
     - The holders of Christiana common stock will not recognize any gain or
      loss for federal income tax purposes as a result of the receipt of
      Weatherford common stock as partial consideration for their Christiana
      common stock in the merger.
    
 
     Prudential Securities has assumed that such taxes are the only relevant
taxes for purposes of the Prudential Securities Opinion other than taxes that
may be applicable to the cash consideration as set forth in such opinion.
Furthermore, for purposes of the Prudential Securities Opinion, Prudential
Securities has assumed that the shareholders of Christiana at the closing of the
merger would be legally entitled to compel performance by C2 of the Lubar/C2
agreement in accordance with its terms in a legal proceeding brought by such
shareholders and Prudential Securities further assumed that the Lubar/C2
agreement would not be amended or modified. In addition, Prudential Securities
has assumed that all purchases of Weatherford common stock by Christiana will be
executed in open market transactions on a nationally recognized securities
exchange or in such other transactions having terms that are at least as
favorable as would have been obtained in such open market purchases at the time
of such other transactions.
 
     Prudential Securities' engagement by Christiana was limited to reviewing
the financial terms of the transaction, and accordingly, the Prudential
Securities Opinion does not address nor should it be construed to address the
relative merits of the transaction or alternative business strategies that may
be available to Christiana. In addition, the Prudential Securities Opinion does
not in any manner address the prices at which Weatherford common stock or C2
common stock will trade following consummation of the merger or the liquidity of
the market that may exist for the C2 common stock. Further, the Prudential
Securities Opinion is necessarily based on economic, financial and market
conditions as they exist and can only be evaluated as of October 12, 1998. For
purposes of rendering the Prudential Securities Opinion, Prudential Securities
assumed that Christiana will not consummate the transaction under circumstances
where the closing price of Weatherford common stock is less than $13.00 per
share on the closing date of the merger.
 
     In addition, the Prudential Securities Opinion was one of the many factors
taken into consideration by the Christiana Board in making their determination
to recommend approval of the transaction. Consequently, the Prudential
Securities Opinion should not be viewed as determinative of the opinion of
 
                                       55
<PAGE>   59
 
the Christiana Board with respect to the fairness, from a financial point of
view, of the transaction to the shareholders of Christiana. The consideration to
be received by the shareholders of Christiana was determined through
negotiations between Christiana and Weatherford and was approved by the
Christiana Board.
 
   
     In arriving at the Prudential Securities Opinion, Prudential Securities
performed a variety of financial analyses, including those summarized herein.
The summary set forth below does not purport to be a complete description of the
analyses performed. The preparation of a fairness opinion is a complex process
that involves various determinations as to the most appropriate and relevant
methods of financial analyses and the application of these methods to the
particular circumstance and, therefore, such an opinion is not necessarily
susceptible to partial analysis or summary description. Prudential Securities
believes that its analyses must be considered as a whole and that selecting
portions thereof or portions of the factors considered by it, without
considering all analyses and factors, could create an incomplete view of the
evaluation process underlying the Prudential Securities Opinion. Prudential
Securities made numerous assumptions with respect to industry performance,
general business, economic, market and financial conditions and other matters,
many of which are beyond the control of Christiana and Weatherford. Estimates of
the values of businesses and securities do not purport to be appraisals or
necessarily reflect the prices at which businesses or securities may be sold. In
addition, Prudential Securities reviewed the following operating projections for
TLC in connection with Prudential Securities' overall analysis of the
transaction:

     As a matter of policy, Christiana does not publicly disclose internal
management forecasts, projections or estimates of the type furnished to
Prudential Securities in connection with its analysis of the transaction, and
such forecasts, projections and estimates were not prepared with a view towards
public disclosure. These forecasts, projections and estimates were based on
numerous variables and assumptions which are inherently uncertain and which may
not be within the control of management of Christiana, including, without
limitation, general economic, regulatory and competitive conditions.
Accordingly, actual results could vary materially from those set forth in such
forecasts, projections and estimates.
 
     Any estimates contained in Prudential Securities' analyses are not
necessarily indicative of actual values or future results, which may be
significantly more or less favorable than suggested by such analyses.
Additionally, estimates of the values of businesses and securities do not
purport to be appraisals or necessarily reflect the prices at which businesses
or securities may be sold. Accordingly, such analyses and estimates are
inherently subject to substantial uncertainty. Subject to the foregoing, the
following is a summary of the material financial analyses conducted by
Prudential Securities in arriving at the Prudential Securities Opinion.
 
   
     Comparable Transactions Analysis. Prudential Securities analyzed the
consideration paid in several recent merger and acquisition transactions deemed
by Prudential Securities to be reasonably similar to the TLC sale and considered
the ratios of the unlevered purchase price ("UPP") to the acquired entities' LTM
earnings before interest and taxes ("EBIT") and LTM EBITDA, based upon
publicly-available information. The transactions considered (the "Comparable
Transactions") were the combinations of:
    
 
   
     - AmeriCold Corporation with JV-Vornado Realty Trust, Crescent Real Estate
       Equities Company ("JV-Vornado").
    
 
   
     - URS Logistics Inc. with JV-Vornado.
    
 
   
     - Christian Salvensen Inc. with CS Integrated LLC.
    
 
                                       56
<PAGE>   60
 
   
     The Comparable Transactions analysis resulted in a range of ratios of UPP
to LTM EBIT of 17.1x to 11.0x and a range of ratios of UPP to LTM EBITDA of 9.9x
to 6.8x. Applying such ratios for the Comparable Transactions to TLC's LTM EBIT
($7.1 million) and LTM EBITDA ($13.5 million) resulted in a range of implied
unlevered market values of $121.2 million to $78.0 million and $133.2 million to
$91.6 million, respectively, or a combined range of implied unlevered market
value based on the Comparable Transactions of $133.2 million to $78.0 million.
The assumed unlevered market value of TLC used by Prudential Securities was
$68.8 million (based upon estimated debt as of June 30, 1998, of $32.8 million,
estimated additional debt of $20.0 million to be incurred immediately prior to
the closing of the merger, and $16.0 million, the implied aggregated equity
value of TLC, based upon a purchase price of $10.7 million for a two-thirds
interest in TLC). Prudential Securities then adjusted the high, low and mean
implied unlevered market values for TLC's LTM EBIT and LTM EBITDA by calculating
the difference between the average level of the Morgan Stanley REIT Index (the
"Index") on the effective date of the Comparable Transactions (332.78) and the
current level of the Index (271.62) and applying the percentage decrease (18.4%)
to the high, low and mean implied unlevered market values for TLC's LTM EBIT and
LTM EBITDA (the "Adjusted Implied Unlevered Market Value") in order to
compensate for the substantial decrease in the multiples of valuation ascribed
to the sector since the effective dates of the Comparable Transactions. The
Adjusted Implied Unlevered Market Values resulted in a range of $98.9 million to
$63.7 million and $108.7 million to $74.8 million, respectively, or a combined
range of Adjusted Implied Unlevered Market Value based on the Comparable
Transactions of $108.7 million to $63.7 million. Prudential Securities observed
that the assumed $68.8 million unlevered market value of TLC falls within the
combined range of Adjusted Implied Unlevered Market Values based on the
Comparable Transactions, which, when considered in conjunction with the C2
offering, supports the Prudential Securities Opinion.
    
 
   
     None of the acquired entities utilized in the above analysis for
comparative purposes is, of course, identical to TLC. Accordingly, a complete
analysis of the results of the foregoing calculations cannot be limited to a
quantitative review of such results and involves complex considerations and
judgments concerning differences in financial and operating characteristics of
the acquired entities and other factors that could affect the consideration paid
for each of the acquired entities as well as that of TLC.
    
 
   
     Projected financial and other information concerning Christiana, TLC and
Weatherford and the impact of the merger upon the holders of Christiana common
stock are not necessarily indicative of future results. All projected financial
information is subject to numerous contingencies, many of which are beyond the
control of management of Christiana, TLC and Weatherford.
    
 
     Transaction Consideration Analysis. Prudential Securities calculated a
total value of $20.22 per share of Christiana common stock for the total
consideration offered in the transaction, representing a premium to Christiana's
closing price as of October 7, 1998 of 12.3%. Prudential Securities did not
perform any analysis with respect to premium/discount paid in comparable
transactions. The value of the total consideration offered per share of
Christiana common stock was based on:
 
     - 0.76 (based on the shares of Weatherford common stock owned by Christiana
       as of October 7, 1998) of a share of Weatherford common stock (the
       "Current Share Exchange Ratio") having a closing price of $18.75 as of
       October 7, 1998.
 
     - An additional $1.94 in Weatherford common stock based on the purchase by
       Christiana of $10.0 million of Weatherford common stock prior to the date
       the proxy statement is mailed (the "Weatherford Common Stock Purchases").
 
     - An anticipated $4.00 per share cash distribution (or $3.00 per share cash
       distribution assuming consummation of $5.0 million additional purchases
       of Weatherford common stock by Christiana), net of taxes and anticipated
       transaction-related expenses.
 
     - Approximately $1.00 in Weatherford common stock only in the event of $5.0
       million additional purchases of Weatherford common stock by Christiana.
 
                                       57
<PAGE>   61
 
     The Current Share Exchange Ratio of .76 of a share of Weatherford common
stock per share of Christiana common stock and the approximate $4.00 or
approximate $3.00 cash distribution number based on the Weatherford Common Stock
Purchases alone and $5.0 million additional purchases of Weatherford common
stock by Christiana, respectively, utilized by Prudential Securities were based
on financial calculations performed by Christiana as of September 30, 1998 and
provided to Prudential Securities. The Current Share Exchange Ratio was derived
by dividing the amount of shares of Weatherford common stock held by Christiana
at September 30, 1998 (3,897,462) by the total outstanding shares of Christiana
on a fully-diluted basis (5,149,330). Based on material supplied by Christiana
as of September 30, 1998, the anticipated approximate $4.00 or approximate $3.00
cash distribution amount (net of taxes and expenses) was derived by subtracting
estimated cash expenses to be paid on, prior to or following the closing of the
merger ("Estimated Cash Expenses") from the anticipated amount of cash held by
Christiana as of the closing of the merger ("Estimated Aggregate Cash"). The
Estimated Aggregate Cash was based on the following items:
 
     - Cash and accrued interest through closing ($5.9 million).
 
   
     - The dividend from TLC ($20.0 million).
    
 
     - The repayment of a promissory note ($3.3 million).
 
   
     - The proceeds from the sale of a two-thirds interest in TLC ($10.7
       million), which items yielded a total amount of Estimated Aggregate Cash
       of $39.9 million.
    
 
Estimated Cash Expenses consisted of:
 
     - $5.7 million for anticipated taxes due.
 
     - $1.7 million for contractual payments on option agreements.
 
     - $1.3 million for anticipated transactional expenses expected to be paid
       prior to closing that are not reflected in the cash balances as of
       September 30, 1998.
 
     - The Weatherford Common Stock Purchases.
 
   
Total anticipated cash available for distribution equaled approximately $21.0
million or an anticipated distribution of $4.00 per share (or approximately
$3.00 per share assuming $5.0 million of additional purchases of Weatherford
common stock by Christiana) of Christiana common stock on a fully-diluted basis.
    
 
     Stock Trading History. Prudential Securities also analyzed the history of
the volume and trading prices for the Christiana common stock and the
Weatherford common stock. Prudential Securities observed that between October 8,
1997 and October 7, 1998, Christiana common stock had an average daily trading
volume of 3,370 shares, with trading prices in the range of $46.38 and $16.88
per share. Between October 8, 1997 and October 7, 1998, Weatherford common stock
had an average daily trading volume of 850,116 shares, with trading prices in
the range of $73.00 and $15.00 per share. Prudential noted that the receipt of
Weatherford common stock in the merger provides Christiana shareholders with a
security of substantially greater liquidity. Prudential Securities also noted
that, as described above under "-- Transaction Consideration Analysis", based on
the market prices of the Weatherford common stock and the Christiana common
stock and the assumed cash consideration, the implied "total" value to be
received by the holders of the Christiana common stock in the merger as of
October 7, 1998, exceeded the closing price of the Christiana common stock on
that date by 12.3%. The combination of the increased liquidity and market
premium as of October 7, 1998, supports the Prudential Securities Opinion.
 
     Christiana selected Prudential Securities to provide a fairness opinion
because it is a nationally recognized investment banking firm engaged in the
valuation of businesses and their securities in connection with mergers and
acquisitions and for other purposes and has substantial experience in
transactions similar to the merger. The engagement letter with Prudential
Securities provides that Christiana will pay Prudential Securities an advisory
fee equal to (1) $50,000, (2) $150,000 upon delivery of the Prudential
Securities Opinion and (3) $250,000 upon consummation of the transaction. In
addition,
 
                                       58
<PAGE>   62
 
the engagement letter with Prudential Securities provides that Christiana will
reimburse Prudential Securities for its out-of-pocket expenses and will
indemnify Prudential Securities and certain related persons against certain
liabilities, including liabilities under securities laws, arising out of the
transaction or its engagement. In the ordinary course of business, Prudential
Securities may actively trade the shares of Christiana common stock and
Weatherford common stock for its own account and for the accounts of customers
and, accordingly, may at any time hold a long or short position in such
securities.
 
AMERICAN APPRAISAL OPINION
 
   
     In connection with the prior merger agreement, which included as a part
thereof the TLC sale, American Appraisal delivered a written opinion (the
"American Appraisal Opinion") to the Board of Directors of each of Christiana,
Weatherford and C2, dated December 1, 1997, that given certain assumptions and
assuming further that the merger pursuant to the prior merger agreement and the
TLC sale are consummated as proposed, immediately after giving effect to
consummation of the TLC sale:
    
 
   
     - The fair value of the aggregate assets of TLC will exceed its respective
       total liabilities, including, without limitation, subordinated,
       unmatured, unliquidated, disputed and contingent liabilities.
    
 
   
     - The present fair saleable value of the aggregate assets of TLC will be
       greater than its respective probable liabilities on its debts as such
       debts become absolute and mature.
    
 
   
     - TLC will be able to pay its debts and other liabilities, including
       contingent liabilities and other commitments, as they mature.
    
 
   
     - TLC will not have unreasonably small capital for the business in which it
       is engaged, as managements of TLC and Christiana have indicated such
       business is now conducted and proposed to be conducted following the
       consummation of the merger pursuant to the prior merger agreement, the
       TLC sale and certain related transactions.
    
 
   
     The full text of the American Appraisal Opinion, which sets forth the
assumptions made, the matters considered and the limitations on the review
undertaken, is set forth as Appendix G to this joint proxy statement/prospectus
and is incorporated herein by reference and should be read in its entirety in
connection with this joint proxy statement/prospectus. The American Appraisal
Opinion is directed only to the solvency of TLC and does not address any other
terms of the merger, the TLC sale or the underlying business decision of
Christiana's Board of Directors or Weatherford's Board of Directors to effect
the merger. The American Appraisal Opinion does not constitute a recommendation
to any stockholder of Christiana or Weatherford as to how any such stockholder
should vote such stockholder's shares of Christiana or Weatherford, as the case
may be. The summary of the American Appraisal Opinion set forth in the joint
proxy statement/prospectus is qualified in its entirety by reference to the full
text of the American Appraisal Opinion attached as Appendix G. American
Appraisal has consented to the use of the American Appraisal Opinion as an
appendix to this joint proxy statement/prospectus.
    
 
   
     The amended merger agreement provides that, as a condition to closing the
transaction, American Appraisal is required to deliver a similar opinion, dated
as of the closing date of the merger, that relates to the revised terms of the
transaction and that applies to C2 and Christiana in addition to TLC. See "The
Merger -- Terms of the Merger -- Conditions to the Merger".

                           RELATED PARTY TRANSACTIONS
 
   
     The following description of the material terms and conditions to the
consummation of the TLC sale is qualified by, and made subject to, the more
detailed terms and conditions set forth in the TLC purchase agreement and the
operating agreement, which are attached as Appendix B and Appendix C to this
joint proxy statement/prospectus and incorporated herein by reference.
    
 
   
THE TLC SALE AND OPERATING AGREEMENT
    
 
   
     Under the terms of the merger agreement, Christiana is required to a sell a
two-thirds interest in TLC to C2 as a condition to Weatherford's obligations to
consummate the merger. In addition, upon the disposition of the two-thirds
interest in TLC to C2, Christiana and C2 are required to enter into the
operating agreement defining their respective rights and obligations with
respect to TLC following the TLC sale.
    
 
   
TERMS OF THE TLC SALE
    
 
   
     General. Immediately prior to the merger, C2 will purchase two-thirds of
TLC for an aggregate purchase price of $10.67 million. As an inducement to
Weatherford to complete the merger, C2 and TLC agreed to assume the Assumed
Liabilities (as defined below). In addition, at any time after the fifth
anniversary of the merger, Christiana will have the option to sell to C2 or TLC
Christiana's one-third interest in TLC for $7.0 million. If there is a proposed
merger or sale of the stock or assets of C2 or if the Lubar family proposes to
sell its interest in C2 so that they would hold less than a 25% interest in C2
or the resulting entity or if C2 proposes to sell its interest in TLC to an
unrelated third party, Christiana will have the right to participate in such
sale with respect to its interest in TLC for the same equivalent consideration.
For other provisions regarding the transfer of interests in TLC, see "-- Terms
of the Operating Agreement -- Assignment, Transfer and Repurchase of a Member's
Units". The TLC sale will take place immediately prior to the closing of the
merger.
    
 
   
     Concurrently with the transaction, C2 will offer 5,202,664 shares of its
common stock pursuant to the C2 prospectus. Immediately prior to the merger,
Christiana shareholders will have the ability to purchase shares of C2 common
stock in an amount up to their pro rata share of Christiana common stock. The
Lubar family has committed to purchase such number of shares of C2 common stock
as is necessary for the net proceeds to C2 of the C2 offering to equal $10.67
million. This will insure that C2 has sufficient funds to complete the TLC sale.
    
 
   
     "Assumed Liabilities" means any and all liabilities and environmental
liabilities, other than the Retained Liabilities (as defined below), to which
Christiana or C2's interest in TLC is or may become subject, whether directly or
indirectly, including, but not limited to, liabilities that result from, arise
out of or relate to:
    
 
   
     - Any Christiana Company (other than TLC).
    
 
     - The business, operations or assets of Christiana or any Christiana
       Company on or prior to the closing of the merger.
 
   
     - Any taxes to which Christiana or any Christiana Company may be obligated
       for periods ending on or before the closing of the merger, except for
       Christiana taxes expressly retained by Christiana pursuant to the merger
       agreement.
    
 
     - Any obligation, matter, fact, circumstance or action or omission by any
       person in any way relating to or arising from the business, operations or
       assets of Christiana or a Christiana Company that existed on or prior to
       the closing of the merger.
 
     - Any product or service provided by Christiana or any Christiana Company
       prior to the closing of the merger.
 
   
     - The merger, the TLC sale or any related transactions.
    
 
                                       60
<PAGE>   64
 
     - Previously conducted operations of Christiana or any Christiana Company.
 
   
     - C2's interest in TLC.
    
 
     "Retained Liabilities" means, and is limited solely to:
 
     - Accounts payable relating to Christiana that are reflected on the balance
       sheet of Christiana at the closing of the merger.
 
     - Accounts payable reflected on the balance sheet of Christiana at the
       closing of the merger and agreed to by Weatherford prior to the closing
       of the merger.
 
     - The obligations of Christiana that arise after the closing of the merger.
 
     - Tax liability for income of Weatherford attributable to Christiana under
       the equity method of accounting either before or after the closing of the
       merger.
 
   
     Indemnification. TLC and C2 have agreed to indemnify, defend and hold
harmless Christiana, Weatherford and their respective officers, directors,
employees, agents and assigns from and against any and all liabilities or
environmental liabilities, including, without limitation, reasonable fees and
expenses of attorneys, accountants, consultants and experts, that such parties
incur, are subject to a claim for or are subject to, that relate to any of a
number of matters, including the following:
    
 
   
     - Any breach of any covenant or agreement of TLC or C2 contained in the TLC
       purchase agreement or any related agreement.
    
 
     - The acts or omissions of Christiana or any of its current or past
       subsidiaries or affiliated companies (a "Christiana Company") on or

     - The acts or omissions of any Christiana Company, TLC, C2 or TLC's or C2's
       affiliates or the conduct of any business by them on or after the closing
       of the merger.
    
 
   
     - The Assumed Liabilities and including, without limitation, any and all
       liabilities and environmental liabilities other than the Retained
       Liabilities to which Christiana or C2's interest in TLC is or may become
       subject resulting from, arising out of or relating to the following:
    
 
   
        - The business or operations of Christiana or any Christiana Company on
          or prior to the closing of the merger.
    
 
   
        - The merger, the TLC sale or any other transactions contemplated
          thereby.
    
 
   
        - Any taxes to which Christiana or any Christiana Company may be
          obligated for periods ending on or before the closing of the merger
          (except for Christiana taxes expressly retained by Christiana pursuant
          to the merger agreement).
    
 
     - Any taxes as a result of the merger subsequently being determined to be a
       taxable transaction.
 
     - Any and all amounts for which Christiana or Weatherford may be liable on
       account of any insurance-related liabilities arising from claims by their
       affiliates, employees or insurance carriers for indemnity arising from or
       out of claims by or against Christiana or any Christiana Company.
 
   
     - Any liability under the Consolidated Omnibus Budget Reconciliation Act of
       1986 with respect to any employees of Christiana or any Christiana

       its obligations to seek to obtain or obtaining any consent or approval to
       assign, transfer or lease any interest in any asset or instrument,
       contract, lease, permit or related benefit.
 
                                       61
<PAGE>   65
 
     - The on-site or off-site handling, storage, treatment or disposal of any
       waste materials generated by Christiana or any Christiana Company on or
       prior to the closing of the merger or any Christiana Company at any time.

       properties owned, leased or operated by Christiana on or after the
       closing of the merger.
 
     - Any acts or omissions on or prior to the closing of the merger of
       Christiana or any Christiana Company relating to the ownership or
       operation of their business or the properties currently or previously
       owned or operated by them.
 
   
     - Any liability relating to any claim or demand by any stockholder of

       related transactions.
    
 
     - Any liability relating to employee benefit or welfare plans of Christiana
       or any Christiana Company arising out of circumstances occurring on or

TERMS OF THE OPERATING AGREEMENT
 
   
     General. Christiana's and C2's interests in TLC will be governed by the
operating agreement. After giving effect to the TLC sale, C2 and Christiana will
be the only members of TLC, which is a Delaware limited liability company.
Additional members may be admitted to TLC only with the unanimous vote or
written consent of the members.
    
 
   
     Allocations. All items of income, gain, loss or deduction of TLC will be
allocated between the members in proportion to their respective ownership
interests and in compliance with the Treasury Regulations promulgated under the
federal tax laws.
    
 
   
     Distributions. To permit the members to make their required estimated
income tax payments arising from their ownership interests in TLC, TLC will make
mandatory distributions to the members in amounts sufficient to cover the
members' respective tax liabilities. TLC may make additional distributions to
the members in proportion to their respective ownership interests upon the
agreement of C2 and Christiania.
    
 
   
     Management. The management of TLC will be vested in a board of managers
with six managers. The initial board of managers will be comprised of William T.
Donovan, Bernard J. Duroc-Danner, Curtis W. Huff, Sheldon B. Lubar, John R.
Patterson and Gary R. Sarner. Each manager is elected by the vote or written
consent of the members holding at least a majority of the ownership interests in
TLC; provided, however, that Christiana and C2 will each be entitled to elect,
without the consent of the other member, a number of managers that is
proportionate to its respective ownership interest in TLC. The operating
agreement provides that certain significant or extraordinary actions or
transactions may be taken or entered into only with the approval of all members.
    
 
   
     TLC will generally indemnify the managers to the fullest extent permitted
under the Delaware law against any losses incurred by reason of any act or
omission in connection with the business of TLC. The board of managers may
appoint officers of TLC to perform such duties as are set forth in the operating
agreement or as specified by the board of managers. The board of managers may
authorize TLC to pay the officers any reasonable fees for their services.
Neither the members nor the managers are required to devote their full time and
efforts to TLC. TLC will pay C2 an annual management fee of $250,000.
    
 
                                       62
<PAGE>   66
 
   
     Assignment, Transfer and Repurchase of a Member's Units. Generally, neither
Christiana nor C2 may transfer its interest in TLC without the prior written
consent of the board of managers. Notwithstanding the foregoing:
    
 
   
     - C2 may transfer its interest in TLC if it complies with the TLC purchase
       agreement.
    
 
   
     - C2 may pledge and assign its interest in TLC to Christiana and Christiana
       may effect a transfer of C2's interest in TLC pursuant to any action
       taken with respect to any security interest granted to Christiana by C2.
    
 
   
     - Christiana may transfer its interest in TLC if the transferee is an
       affiliate of Christiana or C2 and the transferee agrees to be bound by
       the provisions of the operating agreement.
    
 
   
     - At any time after the fifth anniversary of the date of the operating
       agreement, Christiana has the option to sell to C2 or TLC its one-third
       interest in TLC for $7.0 million.
    
 
   
     - At any time after the fifth anniversary of the date of the operating
       agreement, Christiana may transfer any or all of its interest in TLC to
       any person; provided, however, that C2 shall have a right of first
       refusal to purchase such interest for the same price and at the same
       terms as such interest was offered to the transferee.
    
 
   
     In the event of any attempted involuntary transfer of an interest in TLC,
TLC will have the option to purchase the interest subject to the involuntary
transfer at an amount equal to the book value of such interest. An involuntary
transferee receiving an interest in TLC will not be considered a member of TLC
unless all of the members consent in writing to treat the involuntary transferee
as a member. In addition, if there is a proposed merger, consolidation or share
exchange involving C2 or if the Lubar family proposes to sell their interest in
C2 or if C2 proposes to sell its interest in TLC to an unrelated third party,
Christiana will have the right to participate in such sale with respect to its
interest in TLC for the same equivalent consideration.
    
 
   
     Dissolution and Winding Up. TLC will be dissolved upon:
    
 
   
     - The unanimous vote or written consent of the Members to dissolve TLC.
    
 
   
     - TLC being adjudicated insolvent or bankrupt.
    
 
   
     - An entry of a decree of judicial dissolution relating to TLC.

                                   THE MERGER
 
   
     The detailed terms and conditions to the consummation of the merger are
contained in the merger agreement. The following description of the material
terms and conditions to the consummation of the merger is qualified by, and made
subject to, the more detailed terms and conditions set forth in the merger
agreement which is attached as Appendix A to this joint proxy
statement/prospectus and is incorporated in this joint proxy
statement/prospectus by reference.
    
 
TERMS OF THE MERGER
 
   
     General Description of the Merger. At the closing of the merger, Sub will
merge with Christiana and Christiana will be the surviving corporation. Pursuant
to the merger, each outstanding share of Christiana common stock will be
converted into the right to receive the Weatherford share consideration and the
cash consideration. Each holder of a share of Christiana common stock as of the
closing of the merger will be entitled to receive from Weatherford with respect
to each share of Christiana common stock the Weatherford share consideration and
the cash consideration. Based on the current capitalization of Christiana and
the assets and liabilities of Christiana as of September 30, 1998, and after
giving effect to the estimated expenses of the merger payable by Christiana,
Christiana currently expects that, if Christiana makes no additional purchases
of Weatherford common stock, the Weatherford share consideration and the cash
consideration will be .85191 of a share of Weatherford common stock and between
$3.50 and $4.00 in cash, respectively. The specific number of shares of
Weatherford common stock and the exact amount of cash consideration per share of
Christiana common stock payable in the merger will be determined after the
special meetings and could vary from that which would be payable had the merger
been effective on September 30, 1998. If Christiana uses $5.0 million to make
additional purchases of Weatherford common stock, the cash consideration would
drop by approximately $1.00 per share to an estimated $2.50 to $3.00 per share
of Christiana common stock. In addition, Weatherford will determine the cash
consideration following the closing of the merger based on a 30-day post closing
review by Weatherford of the assets and liabilities of Christiana at the closing
of the merger. Weatherford will distribute the cash consideration to the
Christiana shareholders promptly following the calculation of such amount.
    
 
   
     Christiana will be obligated to spend up to $15.0 million to purchase
additional shares of Weatherford common stock in order for the merger to qualify
as a "tax free" reorganization under the federal tax laws. Of this money,
Christiana committed to spend $10.0 million to purchase additional shares of
Weatherford common stock prior to the mailing of this joint proxy
statement/prospectus. Christiana purchased 489,300 shares of Weatherford common
stock at an average price per share of $20.44. Christiana is required to spend
up to an additional $5.0 million cash to purchase additional shares of
Weatherford common stock within one week following the vote at the Christiana
special meeting if necessary to allow the stock component of the consideration
to be paid in the merger to equal at least 80% of the total consideration to be
paid in the merger. In addition, Christiana may, but is not obligated to, make
additional purchases of Weatherford common stock in excess of $5.0 million. If
the market price of the Weatherford common stock is less than $18.30 per share
following the Christiana special meeting, it is expected that it will be
necessary for Christiana to make additional purchases of Weatherford common
stock.
    
 
   
     For each $1.00 drop in the price of the Weatherford common stock below
$18.30 per share, Christiana will have to effect approximately $900,000 in
additional purchases of Weatherford common stock for the merger to qualify as a
partially tax free reorganization. Because Christiana has committed to a maximum
of $5.0 million of additional purchases of Weatherford common stock, the lowest
price for Weatherford common stock at which the merger will be partially tax
free is approximately $12.75 per share. If the price of Weatherford common stock
declines below approximately $12.75 and does not increase above that level prior
to January 31, 1999, the condition that the merger be a partially tax free
reorganization under the Code would not be satisfied and the merger would not be
completed unless Christiana purchased additional shares of Weatherford common
stock to qualify the merger as a partially tax free reorganization. The
following table shows to what extent additional purchases of Weatherford
    
 
                                       64
<PAGE>   68
 
common stock will be necessary and the effect of such additional purchases on
the Weatherford share consideration and the cash consideration.

     As of the record date, there were 97,264,318 shares of Weatherford common
stock outstanding, including the 4,386,762 shares of Weatherford common stock
held by Christiana. Based upon the number of shares of Christiana common stock
outstanding as of the record date, and after giving effect to the conversion of
the 4,386,762 shares of Weatherford common stock held by Christiana into
treasury shares, the number of shares of Weatherford common stock outstanding
after the merger will be the same as prior to the merger.
    
 
     Closing of the Merger. The merger will become effective when the Articles
of Merger are duly filed with the Department of Financial Institutions of the
State of Wisconsin or at such later time (not to exceed 90 days from the date
the Articles of Merger are filed) as is specified in the Articles of Merger
pursuant to the mutual agreement of Weatherford and Christiana. It is
anticipated that, if the merger proposal is approved at the special meetings and
all other conditions to the merger have been satisfied or waived, the closing of
the merger will occur as soon as practicable after the special meetings.
 
     Manner and Basis of Converting Shares. At the closing of the merger, each
share of Christiana common stock issued and outstanding immediately prior to the
closing of the merger not owned directly or indirectly by Christiana shall be
converted into a right to receive the Weatherford share consideration and the
cash consideration. No fractional shares of Weatherford common stock will be
issued, and, in lieu thereof, all fractional shares of Weatherford common stock
that would otherwise be issuable in the merger will be rounded to the nearest
whole share of Weatherford common stock.
 
   
     A letter of transmittal is provided to Christiana shareholders with this
joint proxy statement/prospectus for use in exchanging Christiana common stock
certificates for Weatherford common stock certificates and the cash
consideration. Christiana shareholders should complete the letter of transmittal
in accordance with its instructions and return it to Firstar Bank Milwaukee,
N.A. on or before 5:00 p.m. Central Standard Time on        --       , 1998.
    
 
     Christiana common stock certificates should be submitted with the letter of
transmittal. If such certificates were submitted in connection with the prior
special meeting, no further action need be taken with respect to such
certificates. Christiana shareholders may receive their certificates back at any
time upon request.
 
   
     As soon as possible after the closing of the merger, but no later than 30
days thereafter (the "Payment Date"), the parties to the merger agreement shall
calculate and agree upon the cash consideration (anticipated to be between $3.50
and $4.00 per share of Christiana common stock, or between $2.50 and $3.00 if
Christiana uses $5.0 million to make additional purchases of Weatherford common
stock, based upon the terms of the merger agreement as described more fully in
this joint proxy statement/prospectus). On the Payment Date, Weatherford will
pay the cash consideration due each Christiana shareholder who completed the
letter of transmittal and submitted his or her Christiana common stock
certificates therewith to Firstar Bank Milwaukee, N.A., Milwaukee, Wisconsin
(the "Escrow Agent"), which shall promptly distribute the cash consideration to
each such Christiana
    
 
                                       65
<PAGE>   69
 
shareholder unless such shareholder has elected in the letter of transmittal to
apply all or a portion of the cash consideration to the purchase of shares of C2
common stock as described in the C2 prospectus, in which case the cash
consideration shall be so applied. The Escrow Agent shall, following
instructions from the Christiana shareholders, either transmit such funds to C2
to purchase shares of C2 common stock or transmit such funds to the Christiana
shareholders.
 
   
     Contemporaneously with this joint proxy statement/prospectus, C2 will
deliver to each Christiana shareholder the C2 prospectus regarding the proposed
issuance of C2 common stock. If the merger is approved, each Christiana
shareholder is entitled to purchase shares of C2 common stock and may use the
cash consideration for such purpose by following the procedures described in the
C2 prospectus. The letter of transmittal provided to Christiana shareholders
with this joint proxy statement/prospectus is the means by which Christiana
shareholders may elect to purchase shares of C2 common stock.
    
 
     The rights of the Christiana shareholders regarding the purchase of C2
common stock and the terms upon which the cash consideration may be used to
purchase such shares are governed by the C2 prospectus. Christiana shareholders
should only rely upon that document with regard to the purchase of those shares.
 
     Until such time as a holder of Christiana common stock surrenders such
shareholder's outstanding stock certificate to the Escrow Agent, together with
an appropriately completed and executed letter of transmittal, such shareholder
will have no rights as a stockholder of Weatherford. Such certificate shall
represent only the right to receive upon surrender thereof the number of shares
of Weatherford common stock and the cash consideration into which the shares of
Christiana common stock theretofore represented by such certificate shall be
converted pursuant to the merger agreement. Unless and until such outstanding
certificates are surrendered, no dividends or other distributions payable to the
holders of Weatherford common stock, as of any time on or after the closing of
the merger, will be paid to the holders of such outstanding certificates. Upon
surrender of the certificate previously representing Christiana common stock,
the holder thereof will receive certificates representing the number of shares
of Weatherford common stock to which such shareholder is entitled, the cash
consideration to which such shareholder is entitled and the amount of any
dividends or other distributions, if any, payable to holders of Weatherford
common stock on or after the closing of the merger with respect to such shares,
without interest thereon. Christiana shareholders who submitted their Christiana
common stock certificates in connection with the prior Christiana special
meeting need not take further action with respect to their stock certificates. A
Christiana shareholder may upon request, receive their certificates back at any
time.

       promissory note dated September 1, 1992 in the principal amount of $3.0
       million together with all accrued interest thereon.
    
 
   
     - Except as set forth in the disclosure schedule to the merger agreement,
       or agreed to in writing by Weatherford prior to the closing, Christiana
       shall cause all of its obligations (1) relating to TLC or any other
       historical business of Christiana or its subsidiaries and (2) under any
       and all agreements relating to the borrowing of funds, including all
       guarantees and other similar arrangements relating thereto, to be fully
       released or otherwise satisfied in a manner acceptable to Weatherford.
    
 
     Pursuant to the merger agreement, Weatherford agreed that, from the date of
the merger agreement until the closing of the merger, unless Christiana
otherwise agrees in writing or as otherwise expressly contemplated by the merger
agreement, it would not take any action that would, or that reasonably could be
expected to, result in any of the representations and warranties set forth in
the merger agreement becoming untrue or any of the conditions to the merger set
forth above not being satisfied.
 
   
     Expenses. Christiana is required to bear significant transaction costs,
which costs and the estimates thereof are as follows: Prudential Securities
Opinion ($450,000), legal fees and expenses ($450,000), accounting and tax
services ($250,000), American Appraisal Opinion ($75,000), lease cancellation
($327,000), Weatherford's filing fees with the Commission ($50,000), filing fees
under the HSR Act ($90,000), reimbursement for certain costs incurred by
Weatherford ($900,000), including all printing and proxy solicitation costs and
expenses for blue sky and state securities law filings, and miscellaneous
($208,000). Weatherford is required to pay its own legal and financial advisory
fees. Such costs are estimated as of the date of this joint proxy
statement/prospectus and may be higher. If higher, the cash consideration
available for distribution may be lower. See "Related Party Transactions".
    
 
     Management Following the Merger. No changes in the directors or officers of
Weatherford will be effected as a result of the merger. As of the closing of the
merger, the directors and officers of Sub will become the directors and officers
of Christiana.
 
     Termination or Amendment of the Merger Agreement. The merger agreement
provides that it may be terminated and the merger and the other transactions
contemplated therein may be abandoned at any time prior to the closing of the
merger, whether prior to or after approval by the stockholders of Weatherford or
the shareholders of Christiana, by mutual written consent of Weatherford and
Christiana.
 
     Weatherford or Christiana may also terminate the merger agreement if:
 
   
     - The merger has not been consummated on or before January 31, 1999,
       provided that the right to terminate the merger agreement under this
       provision is not available to any party whose breach of any
       representation or warranty or failure to fulfill any covenant or
       agreement under the merger agreement is the cause of or resulted in the
       failure of the merger to occur on or before such date.
    
 
     - Any court of competent jurisdiction, or some other governmental body or
       regulatory authority, shall have issued an order, decree or ruling or
       taken any other action restraining, enjoining or otherwise prohibiting
       the merger.
 
     - The shareholders of Christiana do not approve the merger proposal at the
       Christiana special meeting or at any adjournment thereof.
 
     - The stockholders of Weatherford do not approve the merger proposal at the
       Weatherford special meeting or any adjournment thereof.
 
                                       70
<PAGE>   74
 
     - In the exercise of its good faith judgment as to its fiduciary duties to
       its stockholders imposed by law, as advised by outside counsel, the Board
       of Directors of Christiana or Weatherford determines that such
       termination is appropriate in complying with its fiduciary obligations.
 
     Christiana may terminate the merger agreement if:
 
   
     - Weatherford fails to comply in any material respect with any of the
       covenants or agreements contained in the merger agreement to be complied
       with or performed by Weatherford or Sub at or prior to such date of
       termination, provided such breach is not cured within 30 days following
       receipt by Weatherford of written notice from Christiana of such breach
       and is existing at the time of termination of the merger agreement.
    
 
   
     - Any representation or warranty of Weatherford contained in the merger
       agreement shall not have been true in all respects when made, provided
       such breach has not been cured within 30 days following receipt by
       Weatherford of written notice from Christiana of such breach and is
       existing at the time of termination of the merger agreement or on and as
       of the closing of the merger as if made on and as of the closing of the
       merger, except to the extent it relates to a particular date, except for
       such failures to be so true and correct which would not, individually or
       in the aggregate, reasonably be expected to have a Weatherford MAE,
       assuming the effectiveness of the merger.
    
 
     - The Board of Directors of Weatherford withdraws, modifies or changes its
       recommendation of the merger proposal in a manner adverse to Christiana
       or shall have resolved to do any of the foregoing.
 
     Weatherford may terminate the merger agreement if:
 
     - Christiana fails to comply in any material respect with any of the
       covenants or agreements contained in the merger agreement to be complied
       with or performed by it at or prior to such date of termination (provided
       such breach is not cured within 30 days following receipt by Christiana
       of written notice from Weatherford of such breach and is existing at the
       time of termination of the merger agreement).
 
   
     - Any representation or warranty of Christiana contained in the merger
       agreement shall not have been true in all respects when made, provided
       such breach has not been cured within 30 days following receipt by
       Christiana of written notice from Weatherford of such breach and is
       existing at the time of termination of the merger agreement or on and as
       of the closing of the merger as if made on and as of the closing of the
       merger, except to the extent it relates to a particular date, except for
       such failures to be so true and correct which would not, individually or
       in the aggregate, reasonably be expected to have a Christiana MAE,
       assuming the effectiveness of the merger.
    
 
     - The Board of Directors of Christiana withdraws, modifies or changes its
       recommendation of the merger proposal in a manner adverse to Weatherford
       or shall have resolved to do any of the foregoing.
 
GOVERNMENTAL AND REGULATORY APPROVALS
 
   
     Under the provisions of the HSR Act, the merger may not be consummated
until such time as the specified waiting period requirements of the HSR Act have
been satisfied. We have filed notification reports, together with requests for
early termination of the waiting period, with the Department of Justice and the
Federal Trade Commission ("FTC") and the applicable waiting period has expired.
At any time before or after the closing of the merger, the Department of
Justice, the FTC or a private person or entity could seek under the antitrust
laws, among other things, to enjoin the merger or to cause Weatherford to divest
itself, in whole or in part, of Christiana or of other businesses conducted by
Weatherford. Although neither Weatherford nor Christiana knows of any reason
that a challenge to the merger would be made under the antitrust laws, there can
be no assurance that a challenge to the merger will not be made.
    
 
     Weatherford and Christiana are aware of no other governmental or regulatory
approvals required for consummation of the merger, other than compliance with
applicable securities laws of the various states.

ACCOUNTING TREATMENT
 
     The merger will be accounted for as a purchase under generally accepted
accounting principles.
 
NYSE LISTING OF WEATHERFORD COMMON STOCK
 
     Pursuant to the merger agreement, Weatherford is required to use reasonable
efforts to obtain listing on the NYSE of the shares of Weatherford common stock
to be issued in connection with the merger. An application for a listing of such
shares on the NYSE, subject to the approval of the merger by the stockholders of
Weatherford, is expected to be filed and approved prior to the closing of the
merger. Approval of the listing on the NYSE of the shares of Weatherford common
stock to be issued in the merger is a condition to the respective obligations of
Weatherford, Christiana and Sub to consummate the merger.
 
FEDERAL SECURITIES LAW CONSEQUENCES
 
     All shares of Weatherford common stock issued in connection with the merger
will be freely transferable, except that any shares of Weatherford common stock
received by persons who are deemed to be "affiliates" (as that term is defined
under the Securities Act) of Christiana prior to the merger may be resold by
them only in transactions registered under the Securities Act, permitted by the
resale provisions of Rule 145 promulgated under the Securities Act (or Rule 144
if such persons are or become affiliates of Weatherford) or otherwise permitted
under the Securities Act. Persons who may be deemed to be affiliates of
Weatherford generally include individuals or entities that control, are
controlled by or are in common control with such party, and may include certain
officers and directors of such party, as well as principal stockholders of such
party.
 
DISSENTERS' RIGHTS
 
     Under Delaware law, the holders of Weatherford common stock who object to
the merger proposal or abstain from voting in favor of the merger proposal will
not have any appraisal rights or right to receive cash for their shares of
Weatherford common stock, and Weatherford does not intend to make any such
rights available to its stockholders.
 
     The following discussion of dissenters' rights under the Wisconsin Business
Corporation Law (the "WBCL") does not purport to be complete and is qualified in
its entirety by reference to the provisions of Section 180.1301 to 180.1331 of
the WBCL. Christiana undertakes to supply a complete copy of the dissenters'
rights provisions upon written request of its respective shareholders to
Christiana Companies, Inc., William T. Donovan, President and Chief Financial
Officer, 700 North Water Street, Suite 1200, Milwaukee, Wisconsin 53202.
 
     Any holder of Christiana common stock who is entitled to vote at the
Christiana special meeting and who objects to the merger may demand payment of
his or her shares of Christiana common stock. Any such shareholder who elects to
exercise such rights and wishes to do so must do the following:
 
     - Before the vote is taken at the Christiana special meeting regarding
       approval of the merger, deliver to Christiana written notice that
       complies with Section 180.0141 of the WBCL of such shareholder's intent
       to demand payment for such shareholder's shares.
 
     - Not vote such shares in favor of approval of the merger.
 
A shareholder may assert dissenters' rights as to fewer than all the shares
registered in such shareholder's name only if such shareholder dissents with
respect to all shares beneficially owned by any one person and notifies
Christiana in writing of the name and address of each person on whose behalf
such record shareholder asserts dissenters' rights. The rights of a shareholder
asserting dissenters' rights as to fewer than all shares registered in such
shareholder's name are determined as if the shares as to which such shareholder
dissents and such shareholder's other shares were registered in the names of
different shareholders. Similarly, a beneficial owner of Christiana common stock
may assert dissenters' rights as to
 
                                       72
<PAGE>   76
 
shares held on the beneficial owner's behalf only if the beneficial owner
submits to Christiana the record shareholder's written consent to the dissent
not later than the time the beneficial shareholder asserts dissenters' rights
and the beneficial owner does so with respect to all shares of which it is the
beneficial owner or over which it has power to direct the vote. All notices to
Christiana should be sent or delivered to its address at the end of the
immediately preceding paragraph.
 
     Not more than ten days after approval of the merger by Christiana
shareholders, Christiana must send to each person who has satisfied the
foregoing requirements for asserting dissenters' rights a notice that complies
with Section 180.0141 of the WBCL which must, among other things:
 
     - State where the demand for payment must be sent.
 
     - State where and when share certificates must be deposited.
 
     - State the extent to which the transfer of the shares will be restricted
       after the demand for payment is received.
 
   
     - Supply a form for demanding payment that includes the date of the first
       announcement to news media, which date was December 15, 1997, or to
       shareholders of the terms of the proposed merger and requires that the
       shareholder or beneficial shareholder asserting dissenters' rights
       certify whether such shareholder acquired beneficial ownership of its
       shares before that date.
    
 
     - Set a date (which must be at least 30 but not more than 60 days after the
       date the dissenters' notice is delivered) by which Christiana must
       receive a demand for payment.
 
     - Be accompanied by a copy of the dissenters' rights provisions of the
       WBCL.
 
   
     A shareholder or beneficial shareholder who receives a dissenters' notice
and wishes to exercise dissenters' rights must submit a written demand for
payment, must certify whether beneficial ownership was acquired prior to
December 15, 1997, and must deposit the applicable share certificates in
accordance with the terms of the dissenters' notice. A shareholder or beneficial
shareholder who does not demand payment in the foregoing manner will not be
entitled to payment for his or her shares under Sections 180.1301 to 180.1331 of
the WBCL. Upon receipt of an appropriate demand for payment and the share
certificates from a dissenting shareholder who certified that beneficial
ownership was acquired before December 15, 1997, Christiana will pay the
dissenting shareholder, provided such shareholder has complied with Section
180.1323 of the WBCL, Christiana's estimate of the fair value of the dissenting
shareholder's shares plus interest, if any, from the date the merger is
consummated. Upon receipt of such demand for payment and the share certificates
from a dissenting shareholder who did not certify that beneficial ownership was
acquired prior to December 15, 1997, Christiana may choose to withhold payment
required by Section 180.1325 of the WBCL from such dissenting shareholder. If
Christiana elects to withhold payment in the foregoing manner, it must offer to
purchase the dissenting shareholder's shares at a price based upon Christiana's
estimate of the fair value of the dissenting shareholder's shares plus accrued
interest, if any.
    
 
     The payment must be accompanied by all of the following:
 
     - Christiana's latest available financial statements, audited and including
       footnote disclosure, if available, including a balance sheet as of the
       end of a fiscal year ended not more than 16 months before the date of
       payment, an income statement for that year, a statement of changes in
       shareholders' equity for that year and the latest available interim
       financial statements, if any.
 
     - Christiana's estimate of the fair value of shares.
 
     - An explanation of how interest was calculated.
 
     - A statement of the dissenting shareholder's right to demand payment under
       Section 180.1328 of the WBCL if dissatisfied with the payment.
 
     - A copy of Sections 180.1301 to 180.1331 of the WBCL.
 
                                       73
<PAGE>   77
 
   
     Within 30 days after receipt of such payment or offer, the dissenting
shareholder either must accept the payment or offer or must notify Christiana in
writing of the shareholder's estimate of the fair value of the shares plus
accrued interest and demand payment of the shareholder's estimate, less any
payment previously received. In the event Christiana fails to make payment to a
person within 60 days after the date set for demanding payment, such person may
notify Christiana in writing of his or her own estimate of the fair value of his
or her shares (and accrued interest) and demand payment of such shareholder's
estimate. If a dissenting shareholder and Christiana cannot agree as to the fair
value of such dissenter's shares, Christiana must, within 60 days after
receiving the demand for payment, commence a special proceeding in the Circuit
Court of Milwaukee County, Wisconsin to determine the fair value of such shares
and accrued interest. If Christiana fails to commence such a proceeding within
such 60-day time period, Christiana must pay to each dissenting shareholder
whose demand remains unsettled the amount each such dissenting shareholder
demands as fair value.
    
 
     Shareholders contemplating exercising dissenters' rights under Wisconsin
law are urged to read carefully the dissenters' rights provisions of the WBCL.
 
                   MATERIAL FEDERAL INCOME TAX CONSIDERATIONS
 
   
     The following discussion of the material United States Federal income tax
consequences of the merger is based in part on an opinion of Arthur Andersen LLP
dated December 23, 1998, and on the current federal tax laws and regulations and
judicial and administrative interpretations thereof. No rulings have been
requested from the Internal Revenue Service (the "IRS") regarding these matters.
Additionally, the opinion of Arthur Andersen LLP is based on various
representations and assumptions, including representations by Weatherford and
Christiana regarding the reasons for the transaction described in "Weatherford's
Reasons for the Transaction" and "Christiana's Reasons for the Transaction", and
is not binding on the IRS or the courts. The conclusions set forth in the
discussion may change as a result of changes in applicable laws or
interpretations thereof occurring after the date hereof. The discussion does not
address the effects of any state, local or foreign tax laws on the merger.
    
 
     THE OPINION OF ARTHUR ANDERSEN LLP ALSO IS REQUIRED TO BE DELIVERED TO
WEATHERFORD AND CHRISTIANA AS A CONDITION TO THE CLOSING OF THE MERGER.
WEATHERFORD AND CHRISTIANA MAY WAIVE THE RECEIPT OF THE OPINION AS A CONDITION
TO CLOSING. EXCEPT FOR MODIFICATIONS TO THE OPINIONS WHICH WOULD NOT CHANGE THE
CONCLUSIONS OF THE OPINIONS DESCRIBED BELOW OR WHICH WEATHERFORD AND CHRISTIANA
DO NOT BELIEVE WILL MATERIALLY CHANGE THE SUBSTANCE OF SUCH OPINIONS, NO WAIVER
OF THE REQUIRED OPINIONS OF ARTHUR ANDERSEN LLP WILL BE EFFECTED BY WEATHERFORD
OR CHRISTIANA WITHOUT DISCLOSURE TO THEIR STOCKHOLDERS OF THE WAIVER, INCLUDING
THE RISKS THEREOF, AND PROVIDING STOCKHOLDERS WITH AN OPPORTUNITY TO CHANGE
THEIR VOTE ON THE TRANSACTION.
 
   
     The tax treatment of a shareholder may vary depending upon his or her
particular situation, and certain shareholders that have a special status may be
subject to special rules not discussed below. Persons that may be subject to
such special rules include individuals who hold restricted Christiana common
stock, individuals who acquired Christiana common stock as a result of the
exercise of an employee stock option, pursuant to an employee stock purchase
plan or otherwise as compensation, insurance companies, tax-exempt
organizations, financial institutions or broker-dealers, persons who do not hold
Christiana common stock as a capital asset and persons who are neither citizens
nor residents of the United States, or who are foreign corporations, foreign
partnerships or foreign estates or trusts not subject to United States Federal
income tax on income regardless of source.
    
 
     EACH SHAREHOLDER IS URGED TO CONSULT HIS OR HER OWN TAX ADVISOR AS TO THE
PARTICULAR TAX CONSEQUENCES TO HIM OR HER OF THE TRANSACTION, INCLUDING THE
APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS, AND OF CHANGES
IN APPLICABLE TAX LAWS.

FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
 
     In the opinion of Arthur Andersen LLP:
 
     - The merger of Sub will constitute a partially tax free reorganization
       under the federal tax laws and Christiana, Weatherford and Sub will be
       parties to the reorganization.
 
     - Neither Weatherford nor Sub will recognize any gain or loss as a result
       of the merger.
 
     - No gain or loss will be recognized by Christiana on the consummation of
       the merger.
 
     - Except for the cash consideration to be received in the merger, a holder
       of Christiana common stock will not recognize any income, gain or loss as
       a result of the receipt of Weatherford common stock in the merger.
 
     - A holder's tax basis in his or her shares of Weatherford common stock to
       be received in the merger will equal such holder's basis in his or her
       shares of Christiana common stock to be surrendered in exchange therefor
       (as determined immediately following the merger) less the cash
       consideration to be received for the holder's shares of Christiana common
       stock and increased by the gain recognized in the merger by the holder.
 
     - A holder's holding period for his or her shares of Weatherford common
       stock to be received in the merger will include the period for which the
       shares of Christiana common stock were held if the shares were held as
       capital assets at the time of the merger.
 
     - Holders of Christiana common stock will recognize gain for the cash
       consideration to be received in the merger. The gain recognized by the
       holders of Christiana common stock in the merger will be a capital gain
       provided the Christiana common stock to be exchanged is a capital asset
       in the hands of the shareholder and provided it is not essentially
       equivalent to a dividend.
 
BACKUP WITHHOLDING
 
     Under the backup withholding rules, a holder of Weatherford common stock
may be subject to backup withholding at the rate of 31% with respect to
dividends and proceeds of redemption, unless such holder (a) is a corporation or
comes within certain other exempt categories and, when required, demonstrates
this fact or (b) provides a correct taxpayer identification number, certifies as
to no loss of exemption from backup withholding and otherwise complies with
applicable requirements of the backup withholding rules. Any amount withheld
under these rules will be credited against the holder's United States Federal
income tax liability. Weatherford may require holders of Weatherford common
stock to establish an exemption from backup withholding or to make arrangements
satisfactory to Weatherford with respect to the payment of backup withholding. A
holder who does not provide Weatherford with his or her current taxpayer
identification number may be subject to penalties imposed by the IRS.
 
                INTERESTS OF CERTAIN PERSONS IN THE TRANSACTION
 
CHRISTIANA OWNERSHIP
 
   
     Christiana currently owns 4,386,762 shares of Weatherford common stock,
which in the aggregate represents approximately 4.5% of the total outstanding
shares of Weatherford common stock. Sheldon B. Lubar is a member of the Board of
Directors of Weatherford and the Chairman of Christiana. Mr. Lubar in his
capacity as a director of Weatherford did not participate in any business of the
Weatherford Board of Directors relating to the merger or any transactions
related to the merger. As of the date of this joint proxy statement/prospectus,
Mr. Lubar beneficially owns, together with his wife (who owns 433,705 shares)
and as trustee of certain trusts for the benefit of his grandchildren, 968,615
shares of Christiana common stock (18.8% of the outstanding shares of Christiana
common stock) and options to purchase an aggregate of 30,000 shares of
Weatherford common stock. In addition, certain members of Mr. Lubar's immediate
family own shares of Christiana common stock in the following amounts: David J.
    
 
                                       75
<PAGE>   79
 
   
Lubar, his son, 427,403 shares (8.2% of the outstanding shares of Christiana
common stock); Joan P. Lubar, his daughter, 448,551 shares (8.6% of the
outstanding shares of Christiana common stock); Kristine L. Thomson, his
daughter, 430,478 shares (8.3% of the outstanding shares of Christiana common
stock); and Susan Solvang, his daughter, 442,953 shares (8.5% of the outstanding
shares of Christiana common stock). As a result of the transaction and assuming
Christiana makes no additional purchases of Weatherford common stock, Sheldon B.
Lubar, David J. Lubar, Joan P. Lubar, Kristine L. Thomson and Susan Solvang,
will own 825,173, 364,109, 382,125, 366,729 and 377,356 shares of Weatherford
common stock, respectively.
    
 
   
     In addition, other directors and executive officers beneficially own shares
of Christiana common stock in the following amounts: Albert O. Nicholas, a
Christiana director, 310,700 shares (6.0% of the outstanding shares of
Christiana common stock); Nicholas F. Brady, a Christiana director, 200,000
shares (3.8% of the outstanding shares of Christiana common stock); William T.
Donovan, President, Chief Financial Officer and a director of Christiana,
167,532 shares (3.3% of the outstanding shares of Christiana common stock); Gary
R. Sarner, Chairman of TLC, 61,000 shares (less than 1.0% of the outstanding
shares of Christiana common stock); and John R. Patterson, President and Chief
Executive Officer of TLC, 45,000 shares (less than 1.0% of the outstanding
shares of Christiana common stock). The amounts reflected for Messrs. Donovan,
Sarner and Patterson include options to purchase 14,000, 55,000 and 32,500
shares of Christiana common stock, respectively. As a result of the merger and
assuming there are no additional purchases of Weatherford common stock, Messrs.
Nicholas, Brady, Donovan, Sarner and Patterson will own 264,688, 170,382,
142,722, 51,967 and 38,336 shares of Weatherford common stock, respectively.
    
 
   
     Christiana's executive officers and directors, like all other Christiana
shareholders, will be entitled to purchase one share of C2 common stock for each
share of Christiana common stock held immediately prior to the completion of the
merger. In addition, the Lubar family agreed to purchase enough shares of C2
common stock as are necessary for the net proceeds of the C2 offering to equal
$10.67 million to fund C2's purchase of two-thirds of TLC. This will insure that
C2 has sufficient funds to complete the TLC sale, after deducting the expenses
of the C2 offering.
    
 
     Certain executive officers and directors of Christiana will be executive
officers and directors of C2, and, to the extent such officers and directors are
Christiana shareholders, they will have the ability to purchase their pro rata
interest in C2 pursuant to the C2 offering. Assuming all shareholders of
Christiana exercise their ability to purchase their pro rata interest in C2
pursuant to the C2 offering, the Lubar family and the other officers and
directors of C2 would beneficially own approximately 66% of the outstanding
shares of C2 common stock. To the extent Christiana shareholders do not exercise
their ability to purchase their pro rata interest in C2, the beneficial
ownership interest in C2 of the Lubar family and the other directors and
officers of C2 will increase, and such persons could potentially own up to 100%
of C2 common stock.
 
     Under the terms of the merger agreement, all employee stock options of
Christiana are required to be exercised or cancelled prior to the merger. As a
result, the executive officers and other individuals who hold options to
purchase shares of Christiana common stock were given a choice of either of the
following:
 
   
     - Cancel, in whole or in part, their options in exchange for an amount
       equal to the (1) difference between $40.00 and the option exercise price,
       multiplied by (2) the number of shares subject to the cancelled option.
       This price was fixed at the time the merger agreement initially was
       entered into and is substantially greater than the current market price.
       Christiana's cash payments to such persons will be reduced to the extent
       necessary to allow Christiana to deduct the full amount of the payments
       for federal income tax purposes.
    
 
     - Exercise their options prior to the closing of the merger.

(1) On May 27, 1998, Weatherford acquired Weatherford Enterra, Inc., issuing
    additional shares of Weatherford common stock and thereby reducing
    Christiana's ownership percentage in Weatherford to approximately 4%. As a
    result, on May 27, 1998, Christiana changed the manner in which it accounts
    for its investment in Weatherford from the equity method to the cost method.
    Under the cost method, only dividends paid by Weatherford will be reflected
    in future earnings of Christiana.
 
(2) All earnings per share amounts have been restated to reflect the adoption of
    Statement of Accounting Standards No. 128, "Earnings Per Share", effective
    December 15, 1997.
 
(3) Includes $21.4 million and $57.8 million of unrealized holding gains on
    securities available-for-sale as of September 30, 1998 and June 30, 1998,
    respectively, resulting from a change in the method of accounting for
    Christiana's investment in Weatherford.

         NOTES TO PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
GENERAL
 
     These notes describe the assumptions used to prepare the unaudited pro
forma condensed consolidated financial statements. The pro forma adjustments are
based on estimates made by Weatherford's management using information currently
available.
 
PRO FORMA ADJUSTMENTS
 
     The adjustments to the accompanying Unaudited Pro Forma Condensed
Consolidated Balance Sheet are the following:
 
   
(a)  This adjustment reflects the sale of a two-thirds interest in TLC by
     Christiana to C2 for cash of $10.67 million and reflects a $3.0 million
     loss, net of taxes of $1.9 million. The loss results from the sale price
     being less than the $15.6 million carrying value of the two-thirds interest
     in TLC. The sale is in accordance with the merger agreement as (1) TLC is
     required to distribute $23.0 million to Christiana, funded from borrowings
     of TLC to permit Christiana to have sufficient cash to allow Weatherford to
     pay the cash consideration, (2) Christiana is required to sell its
     two-thirds interest in TLC to C2 for $10.67 million and (3) Weatherford is
     required to pay to the Christiana shareholders an amount of cash equal to
     the cash held by Christiana in excess of the amount of accrued unpaid taxes
     (without giving effect to the value of certain tax deductions to be
     retained by Christiana) and fixed liabilities at the closing of the
     transaction to be maintained by Christiana for the benefit of Weatherford.
    
 
   
(b)  This adjustment reflects Christiana's purchase in the open market of $10.0
     million, or 489,300 shares, of Weatherford common stock at an average
     market price of $20.44 per share. Subsequent to this purchase, Christiana's
     investment in Weatherford represents 4,386,762 shares of Weatherford common
     stock; accordingly, 4,386,762 shares of Weatherford common stock will be
     distributed to the Christiana shareholders as a result of the merger.
    
 
   
(c)  This adjustment reflects the receipt by Christiana of $23.0 million from a
     dividend from TLC funded through TLC's borrowings to meet the required
     minimum cash levels required by the merger agreement, and reflects the
     receipt by Christiana of $10.67 million from its sale of the two-thirds
     interest in TLC less $0.4 million of cash held by TLC.
    
 
(d)  This adjustment reflects the pro forma cash payment by Weatherford of $18.9
     million ($3.67 per share) to the holders of Christiana common stock
     pursuant to the merger agreement. The pro forma cash payment by Weatherford
     of $3.67 per share is based on the pro forma data as of September 30, 1998;
     however, Christiana currently estimates that such payment will be between
     $3.50 and $4.00 per share. The cash payment difference of $0.33 per share
     reflects expected cash flow through the anticipated closing and timing
     differences for cash expenditures, including taxes, for the period from
     October 1, 1998, to closing, not reflected in the historical financial
     information of Christiana. Both the pro forma cash payment by Weatherford
     of $3.67 per share and Christiana's estimate of a cash payment between
     $3.50 and $4.00 per share assume Christiana is not required to make
     additional purchases of up to $5.0 million of Weatherford common stock. If
     Christiana makes additional purchases of Weatherford common stock of $5.0
     million, Christiana estimates that the pro forma cash payment would be
     between $2.50 and $3.00 per share.
 
   
(e)  This adjustment reflects the cancellation of Christiana employee stock
     options for $1.7 million in cash. The cancellation of Christiana employee
     stock options generates a tax benefit of $0.6 million and a reduction in
     retained earnings of $1.1 million. Cash in the amount of the tax benefit,
     $0.6 million, is required to be retained by Christiana for the benefit of
     Weatherford.
    
 
(f)  This adjustment records a $3.0 million liability, net of $1.3 million of
     expenses paid as of September 30, 1998, for transaction costs related to
     the transaction.

                          NOTES TO PRO FORMA CONDENSED
                CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
   
(g)  This adjustment eliminates Christiana's investment of $94.3 million in
     4,386,762 shares of Weatherford common stock, related deferred taxes of
     $24.4 million and unrealized gain on securities available-for-sale of $21.4
     million.
    
 
   
(h)  This adjustment reflects the remaining one-third interest in TLC held by
     Christiana. The investment represents a one-third interest in the net book
     value of TLC.
    
 
   
(i)  Prior to the sale of Christiana's two-thirds interest in TLC, the pro forma
     net book value of TLC was $23.4 million at September 30, 1998. After the
     sale of Christiana's two-thirds interest in TLC, the remaining net book
     value of TLC is $7.8 million. Weatherford reflects a reduction of $3.2
     million in the carrying value of Christiana's remaining one-third interest
     in TLC to reflect the negative goodwill resulting from this transaction.
     The negative goodwill is calculated as follows:

(j)  This adjustment reflects the current federal taxes payable of $8.3 million
     resulting from the sale by Christiana of its two-thirds interest in TLC.
     This liability had previously been provided as a deferred tax liability.
    
 
   
(k)  This adjustment reflects the issuance of 4,386,762 shares of Weatherford
     common stock in the transaction at a price of $23.00 per share, or $100.9
     million, the market price of the Weatherford common stock on September 22,
     1998, and the acquisition of 4,386,762 shares of Weatherford common stock
     held by Christiana as a result of the transaction. The shares of
     Weatherford common stock held by Christiana have been classified as
     treasury shares valued at the market price of $23.00 per share, or $100.9
     million, on September 22, 1998.
    
 
(l)  This adjustment eliminates the remaining Christiana common stock of $5.2
     million, capital in excess of par of $12.3 million, retained earnings of
     $58.5 million and treasury stock of $1.2 million.
 
     The adjustments to the accompanying Unaudited Pro Forma Condensed
Consolidated Statements of Income are the following:
 
   
(m)  This adjustment eliminates TLC's historical operating results and reflects
     a one-third equity interest in TLC.
    
 
(n)  This adjustment eliminates Christiana's equity in earnings of Weatherford.
 
(o)  This adjustment records the income tax benefit related to the effect of the
     pro forma adjustments at the statutory rate.
 
(p)  Weatherford's historical shares outstanding and basic weighted average pro
     forma post merger shares outstanding as of December 31, 1997, were
     96,860,622 and 96,051,625, respectively. Weatherford's historical shares
     outstanding and basic weighted average pro forma post merger shares
     outstanding as of September 30, 1998, were 97,458,439 and 96,972,605,
     respectively.

                           DESCRIPTION OF CHRISTIANA
 
BUSINESS
 
   
     General.  Christiana's only operating entity is TLC. Christiana also owns
4,386,762 shares of Weatherford common stock, which represents approximately
4.5% of the outstanding shares of Weatherford common stock. Christiana also
holds, through a wholly owned subsidiary, mortgage notes receivable, derived
from certain condominium sales, which as of September 30, 1998, had an aggregate
principal amount outstanding of $187,000.
    
 
     Christiana was incorporated in 1954 as a Delaware corporation and was
reincorporated in 1992 as a Wisconsin corporation. The principal executive
offices of Christiana are located at 700 North Water Street, Suite 1200,
Milwaukee, Wisconsin 53202, and its telephone number is (414) 291-9000.
 
   
     TLC.  TLC provides refrigerated and dry (non-refrigerated) warehousing,
transportation and distribution services and international freight forwarding
services. TLC's industry is comprised generally of entities that provide
warehousing or trucking and other entities that provide management services for
the distribution and warehousing needs of their customers. TLC believes that its
ability to offer customers "one-stop shopping" through its complement of
warehousing, trucking and the provision of management services for distribution
and warehousing needs provides it with a competitive advantage. Christiana's
services generally combine transportation, warehousing and information services
to manage the distribution channel for a customer's products from the point of
manufacturing to the point of consumption. This combination allows TLC to
capitalize on the growing trend of corporations toward seeking to reduce costs
by outsourcing large components of their logistics function.
    
 
   
     TLC's operations are conducted through a network of 12 distribution
warehouses, comprised of an aggregate of 34 million cubic feet of refrigerated
and frozen storage capacity in six locations and five dry distribution centers
in key markets, primarily in the upper Midwest. TLC's refrigerated warehousing
operations include temperature sensitive storage services, freezing vegetable
processing and packaging services. TLC's transportation and distribution
services include refrigerated and non-refrigerated transportation services, full
service truckload and less-than-truckload. Transportation services are provided
utilizing Christiana-owned equipment as well as through carrier management
service. TLC also provides a full range of international freight management
services, fully computerized inventory management, assembling and repackaging.
    
 
   
     Revenues. TLC's revenue for each of the basic service lines are detailed
below for fiscal years ended June 30, 1998, 1997, and 1996.

     As of September 30, 1998, the pro forma book value of TLC was approximately
$25 million.
    
 
   
     Customers. TLC's services target the consumer goods industries. Nearly 75%
of TLC's revenues come from food manufacturers, food wholesalers and food
retailers.
    
 
   
     While TLC's top 15 customers, all of which participate in the food
industry, account for 60% of revenues, no one customer represents more than 10%
of the business. Beyond the food industry, the balance of TLC's customer base is
spread across a broad base of industries including pharmaceuticals, automotive
suppliers, building supplies and office furniture.

<PAGE>   93
 
   
     Competition. Competition in TLC's industry is very fragmented. Leonard's
Guide, a leading industry publication, lists more than 1,500 companies competing
in the United States marketplace. Among TLC's competitors are companies, such as
Exel, AmeriCold Logistics, Inc. (formerly Americold Corporation), GATX
Logistics, Inc., ProLogis, Inc. or Ryder Integrated Logistics, Inc. that own and
operate warehouses and/or transportation equipment. These companies utilize
their asset base and the expertise with which to operate them to provide
services. Other competitors, such as Hub Group Logistics Services, Menlo
Logistics, and C.H. Robinson Logistics offer transportation and distribution
management expertise and information systems and sub-contract warehousing and
transportation services.
    
 
   
     TLC experiences competition for transportation management services on a
national basis. In its warehousing and transportation business, TLC competes
generally on a regional and local basis. Other than the high capital
requirements of building a refrigerated warehouse facility, there are no
significant barriers to entry into the transportation, warehousing and
management service markets in which TLC operates, permitting a large number of
smaller competitors to enter the various markets.
    
 
   
     In addition, TLC's customers, many of which have substantially greater
resources than TLC, may divert business from TLC's warehousing and
transportation operations by building their own warehouse facilities and/or
operating their own transportation fleet.
    
 
   
     Organization. TLC's operations are headquartered in Zeeland, Michigan, and
TLC also maintains an office in Milwaukee, Wisconsin. TLC is organized into
three main operating units: refrigerated warehousing, dry warehousing and
transportation. Each operating unit is headed up by a group vice
president/general manager. Sales and marketing for TLC are principally performed
at the corporate level, with support from the group vice presidents as well as
local warehouse facility managers.
    
 
   
     Sales and marketing are principally performed at the corporate level, with
support from the group vice presidents and facility managers. The sales
organization is comprised of seven individuals and is divided into the following
teams: refrigerated warehousing team; dry warehousing team; transportation team;
and logistics sales team. Each of these teams has primary responsibility for
selling their specific services. The goal is to develop the sales team to
effectively present the fullest extent of TLC's services suited for each
customer.
    
 
     Marketing and advertising is done centrally for the entire company and uses
a combination of media advertising and direct mail. The marketing organization
also has responsibility for maintaining and gathering information on market
intelligence related to competition, customers and the logistic industry in
general.
 
     Business development supports both sales and operations by providing
logistics engineering capabilities, pricing and costing services, and assists in
the startup of complex logistic projects.
 
   
     The only employees of Christiana are the executive officers described under
"Directors and Executive Officers". TLC had approximately 737 employees as of
September 30, 1998. A breakdown of the employees by functional area is set forth
below:

     Weatherford.  Christiana owned 3,897,462 shares of Weatherford,
representing an approximate 4% ownership interest as of September 30, 1998.
Christiana's holdings in Weatherford resulted from the June 30, 1995 merger of
Prideco, a former majority owned subsidiary of Christiana, with a subsidiary of
Weatherford and a $13.2 million cash investment to purchase additional
Weatherford shares in connection with the Prideco merger transaction. Prior to
December 8, 1998, Christiana purchased an additional 489,300 shares of
Weatherford common stock pursuant to the amended merger agreement.
    
 
PROPERTIES
 
   
     As of September 30, 1998, TLC owned or leased twelve facilities in five
states. Of this total, seven are refrigerated/frozen with the balance being dry
facilities. The refrigerated facilities are operated through seven public
refrigerated warehouses located in Wisconsin (2), Michigan (3), and Illinois
(2). TLC's refrigerated facilities are large single-story buildings constructed
at dock height with full insulation and vapor barrier protection. These
facilities are strategically located and well served by rail and truck.
    
 
     In addition to the refrigerated facilities discussed above, there are five
public non-refrigerated (or dry) warehouse distribution facilities, three of
which are located in Michigan and one in each of Indiana and New Jersey. Zeeland
Distribution Center II, located in Zeeland, Michigan is a company-owned
facility. All other dry facilities are held under lease. Lease terms generally
match the underlying contracts with major customers served at each facility.
These facilities are single-story block or metal construction buildings. All dry
facilities are approved as food grade storage facilities.
 
     The following tables list the twelve facilities by location, size, type,
and if owned or leased.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
  Three months ended September 30, 1998 compared to three months ended September
30, 1997
 
   
     Christiana's consolidated revenues for the three months ended September 30,
1998 were $22,370,000 compared to $23,047,000, reflecting a decline of 2.9% due
primarily to the closure of two dry warehouses offset partially by a 3.8%
revenue gain in refrigerated warehousing services. Volume growth in refrigerated
warehousing services resulted primarily from increased capacity utilization, due
both to new customer relationships and expanded programs with existing customers
at the Rochelle and Milwaukee Logistic Centers. Revenues for the quarter
attributable to transportation services were level with the prior year's period.
    
 
   
     Earnings from operations for the quarter were $1,372,000 compared to
$1,617,000 for the same period last year. Operating earnings contributed by TLC
totaled $1,764,000 in the first quarter compared to $1,987,000 for the same
period last year. The decline in operating earnings was primarily attributable
to increased depreciation, marketing and administrative expenses directed at
developing new value-added service programs.
    
 
     Consolidated net earnings for the quarter were $502,000 or $0.10 per share
compared to $1,485,000 or $0.29 per share for the same period last year.
Included in the prior year's period results were equity earnings of Weatherford
which contributed net earnings of $1,178,000 or $0.23 per share. Since May 27,
1998, Christiana no longer reports its proportionate share of Weatherford's
earnings under the equity method. On a comparable basis, without equity earnings
of Weatherford, Christiana's net earnings increased 64% from $307,000 to
$502,000 quarter to quarter. The improvement in net earnings for the quarter,
adjusted to eliminate Weatherford's contribution, was primarily due to reduced
interest expense and other charges related to litigation settlement and facility
closures which were incurred in the comparable period last year.
 
     Interest income was lower in the quarter compared to the same period last
year due both to lower rates available on short-term U.S. government securities
and lower principal amount of mortgage notes receivable.
 
     Interest expense was lower this period due primarily to reduced borrowings
resulting from $9,699,000 of debt reduction during the last twelve months ended
September 30, 1998.
 
  Net earnings for past three fiscal years.

  Fiscal 1998 compared to Fiscal 1997.
 
   
     Christiana's consolidated revenues for fiscal 1998 were $90,179,000
compared to $84,208,000 reported for fiscal 1997, an increase of $5,971,000 or
7.1%. Revenue growth at TLC was primarily attributable to volume increases in
logistic services which include carrier management services, transportation
management services and transportation operations. During fiscal 1998, revenues
attributable to logistic services increased $6,049,000 or 18.1% over the prior
year due to operation of an expanded fleet and strong demand for transportation
services. Revenue growth in Refrigerated Warehousing services was $1,686,000 or
5.1% in fiscal 1998 due primarily to increased utilization of existing
facilities from both new and existing customer relationships. Revenues from Dry
Warehousing operations in fiscal 1998 declined $3,599,000 or 29.9%, due to the
closure of two facilities at the end of fiscal 1997 consistent with TLC's
strategy to de-emphasize public dry warehousing activities. The balance of the
revenue increase in fiscal 1998 of $1,835,000, is primarily attributable to
expanded volume in distribution services of food products to the State of
Michigan Department of Education under a new five-year contract.
    
 
   
     Gross profit for the year increased $887,000 or 6.7% to $14,122,000. Each
of TLC's service lines with the exception of Dry Warehousing had increased gross
profit due primarily to better utilization of the assets, improved productivity
and strong cost controls. TLC services increased gross profit by $1,009,000 or
38.5%, due to volume growth, higher utilization of revenue producing assets and
an expanded fleet compared to fiscal 1997. Refrigerated Warehousing operations
increased gross profit by $465,000 or 6.0%, through increased capacity
utilization of facilities and strong cost control. Dry Warehousing had a decline
in gross profit of $494,000 or 26% primarily due to reduced revenues in this
area. Distribution services gross profit increased $240,000 or 49%, due to
higher volume attributable to a new five-year contract with Michigan Department
of Education covering an expanded region of service.
    
 
   
     Selling, general and administrative expenses for the year were reduced
$292,000 due primarily to lower corporate related expenses. Selling, general and
administrative expenses at TLC increased $305,000 or 4.3% in fiscal 1998 due to
increased sale and marketing activities designed to grow TLC services.
    
 
     Earnings from operations of $5,758,000 increased $1,179,000 or 25.7%,
compared to $4,579,000 reported for fiscal 1997. The improvements in earnings
from operations is attributable to revenue growth, improved operating margins
and lower corporate overhead expense.
 
   
     Interest expense in fiscal 1998 was $2,691,000, a reduction of $475,000
from the prior year due to strong cash flow from TLC which enabled over
$9,000,000 of debt reduction during fiscal 1998.
    
 
     Net earnings in fiscal 1998 totaled $6,007,000 or $1.17 per share ($1.15
diluted) compared to $6,663,000 or $1.30 per share ($1.29 diluted) in fiscal
1997. The decline in net earnings reported for this period is primarily
attributable to two items: in last year's period, Weatherford sold Mallard Bay
Drilling, realizing a $66,900,000 one time after tax gain which resulted in
Christiana recording an after tax gain of $3,475,000 and in this fiscal year,
Christiana incurred a $589,000 after-tax charge related to the settlement of
litigation. Net earnings in fiscal 1998 include equity in earnings of
Weatherford of $4,786,000 for 11 months ended May 27, 1998 when Christiana
changed the method of accounting for its Weatherford investment to the cost
method.
 
  Fiscal 1997 compared to Fiscal 1996.
 
   
     Christiana's consolidated revenues for fiscal 1997 were $84,208,000
compared to $77,170,000 reported for fiscal 1996, an increase of 9.1%. Revenue
growth was primarily attributable to increased volume in transportation and
refrigerated warehousing services. The most significant improvement was in
transportation revenues which increased 20.6% over the previous year. During
fiscal 1997, TLC secured a large multi-year contract to provide logistic
services to a major frozen food producer. This contract, as well as certain
management changes, enabled Christiana to significantly improve the operating
performance in transportation related logistic services during fiscal 1997.
Refrigerated warehousing services revenues increased 14.7% over last year's
level due primarily to increased utilization of the expanded capacity at the
    
 
                                       95
<PAGE>   99
 
   
Rochelle TLC Center and higher utilization at all the Michigan based
refrigerated facilities during fiscal 1997.
    
 
   
     Revenue growth combined with aggressive cost management resulted in a 1%
increase in gross margin. During fiscal 1997, TLC closed two dry public
warehouses which were leased facilities, Atlanta, Georgia and Sparks, Nevada.
The closure of these facilities resulted from Christiana's inability to secure
longer term value-added logistic services contracts in line with Christiana's
strategic focus on dry warehousing operations. Warehousing and TLC expenses were
negatively impacted by $358,000 of charges related to warehouse closures and
corporate restructuring. Selling, general and administrative expenses increased
$1,125,000 or 14.9% due mainly to increased marketing and sales activities.
Earnings from operations increased $358,000 or 8.5% to $4,579,000 in fiscal 1997
from $4,221,000 in fiscal 1996.
    
 
   
     Loss on disposal of assets of $765,000 was primarily related to a
$1,085,000 charge incurred in the disposal of special freezing equipment in
connection with securing a long term contract for vegetable processing,
freezing, and warehouse services with a major customer of the Beaver Dam TLC
Center. In addition, in fiscal 1997 gains on the sales of real estate totaled
$271,000 which included the final sales of the 366 condominium home project in
San Diego. In fiscal 1996, gains on sales of real estate were $2,818,000.
    
 
   
     Consolidated net earnings for fiscal 1997 were $6,663,000, or $1.30 per
share, up 85% from last year's level of $3,603,000, or $.69 per share. The
principal factors impacting net earnings in fiscal 1997 were the growth in
equity earnings in Weatherford and improved operating performance at TLC.
    
 
   
  Financial Condition, Liquidity and Capital Resources.
    
 
     Cash equivalents and short-term investments totaled $5,286,000 at September
30, 1998 compared to $5,539,000 at June 30, 1998, a decrease of $253,000.
Christiana's working capital at June 30, 1998 was $3,493,000 compared to
$4,257,000 at June 30, 1997.
 
     Operating activities for the fiscal year ended June 30, 1998 provided cash
of $7,944,000 derived primarily from net earnings, depreciation and amortization
partially offset by equity in earnings of Weatherford. Operating activities for
the three month period ended September 30, 1998 provided cash of $1,273,000
attributable primarily to net earnings, depreciation and amortization and
increased accounts payable and accrued liabilities offset by increased accounts
receivable, and inventories.
 
   
     Capital expenditures for the fiscal year ended June 30, 1998 totaled
$2,829,000, the major components of which were: $1,671,000 for machinery and
equipment additions primarily related to warehousing operations; $400,000 for
leasehold improvements at the corporate office; and $163,000 for computer
systems. The remaining expenditures were incurred for equipment and facility
improvements within the dry warehousing and transportation segments. Capital
expenditures for the three month period ended September 30, 1998 of $546,000
were attributable to TLC.
    
 
     Investing activities for the fiscal year ended June 30, 1998 provided cash
of $3,685,000 derived primarily from $4,611,000 of proceeds of short-term
investments and $1,217,000 from payments on mortgage notes receivable partially
offset by the sale of mortgage notes receivable and mortgage prepayments.
Investing activities for the three month period ended September 30, 1998 used
cash of $67,000 primarily from capital expenditures offset by a decrease in
mortgage notes receivable and sale of assets.
 
     Cash used in financing activities for the fiscal year ended June 30, 1998
resulted in the reduction of long term debt by $9,555,000. Net cash used in
financing activities to reduce debt in the three month period ended September
30, 1998 totaled $1,459,000.
 
     Christiana's balance sheet at June 30, 1998, reflects $144,206,000 as its
carrying value for 3,897,462 shares of Weatherford common stock. This represents
the fair market value of Christiana's holding in Weatherford at June 30, 1998.
Weatherford has not paid dividends on Weatherford common stock since 1984 and it
is anticipated, for the foreseeable future, that its earnings will be retained
for the development
 
                                       96
<PAGE>   100
 
of its business. As of September 30, 1998, the fair market value of this
investment decreased from $144.2 million at June 30, 1998 to approximately $84.3
million as a result of market fluctuations.
 
     At September 30, 1998 Christiana had in place a $15 million unsecured line
of credit for general corporate purposes. Borrowings under this line of credit
bear interest on a floating rate of LIBOR plus 125 basis points or prime at
Christiana's option. There were no borrowings under this facility during the
fiscal year ended June 30, 1998 or at September 30, 1998.
 
   
     TLC has available to it a revolving credit facility at a floating rate of
LIBOR plus 175 basis points. This facility will finance TLC's capital needs, the
$20.0 million dividend to Christiana and the repayment of the promissory note to
Christiana in the amount of $3.0 million, plus interest. After the merger it is
anticipated that TLC will have approximately $17.0 million of additional
borrowing capacity under its revolving credit facility.
    
 
     Christiana's current sources of capital include: cash generated from
operations, sale of remaining mortgage portfolio, borrowings under its revolving
credit agreement and line of credit and the use of its marketable Weatherford
shares. Christiana believes that current reserves of cash and short-term
investments, access to existing credit facilities and internally generated cash
from operations are sufficient to finance the projected cash requirements of its
current operations.
 
     Christiana continues to evaluate new acquisitions in areas strategic to
existing operations as well as new lines of business. However, while Christiana
is a party to the merger agreement with Weatherford, Christiana is restricted
from making acquisitions without the approval of Weatherford. Future
acquisitions may be funded through cash flow from operations, liquidation of
mortgage notes receivable, liquidation of Weatherford common stock, borrowings
under its existing line of credit and other facilities, and equity issuance if
desirable.
 
     As of September 30, 1998, Christiana had no material capital commitments.
 
  Year 2000 Disclosure.
 
     During fiscal 1998, Christiana completed a comprehensive assessment of its
Year 2000 problem for both its financial information systems and other
non-financial systems. In the opinion of Christiana management, all hardware and
software that could have a significant Year 2000 problem have been identified
and a remediation plan has been implemented. Year 2000 problems for financial
information systems are being corrected through hardware and software upgrades.
Non-financial systems, primarily telephone and security, will be repaired or
replaced in order to achieve Year 2000 compliance. Based on Christiana's current
projections, all Year 2000 compliant systems, both financial and non-financial,
will be implemented no later than January 1, 1999 to allow for sufficient
testing. As of September 30, 1998, Christiana was approximately 70% complete
with the installation of its Year 2000 compliant upgrades. By the time these
upgrades are completed, Christiana estimates that it will have expended
approximately $950,000 to resolve its Year 2000 problem.
 
   
     Christiana believes that its efforts are sufficient to address its Year
2000 problem. However, there can be no assurance that Christiana will be
successful in its efforts. Any failure to address the Year 2000 problem will
have a material adverse effect on the ability of TLC to provide its
transportation and warehousing services and process vital financial data. This
could result in a material loss of revenues to Christiana in amounts which are
not known at this time. Christiana currently has no contingency plans if its
efforts to address the Year 2000 problem fail. After Christiana has completed
the upgrades described above, contingency plans will be developed.
    
 
   
     TLC has solicited all of its major service providers concerning their
progress in compliance with the Year 2000 problem. TLC has received responses
from such providers and is not aware of the inability of any service provider to
address its Year 2000 problem.

     The entire unpaid principal balance of loans made under the credit
agreement will be due and payable on November 2, 2003.
 
   
     The proceeds of the initial loans under the credit agreement were used to
refinance existing indebtedness of TLC in the amount of approximately $32.0
million. Additional loans will finance the payment of a distribution to
Christiana of $20.0 million cash and the repayment of $3.0 million, plus
interest, under the note to Christiana. The available balance of the facility,
estimated to be $17.0 million after completion of the merger, will be available
for working capital and general corporate purposes, including the issuance of
letters of credit of up to $3.5 million outstanding at any one time.
    
 
   
     The credit agreement is secured by liens or security interests on all or
substantially all of the assets of TLC, other than certain transportation
equipment, and mortgages on its real estate.

     The interest rate on borrowings under the credit agreement after the C2
offering is expected to be, at the option of TLC, LIBOR plus 175 basis points or
the prime rate, less 25 basis points. These rates will vary over the term of the
credit agreement pursuant to a pricing grid based on the ratio of consolidated
funded debt to consolidated EBITDA, all as defined in the credit agreement, in
accordance with the following table:

The credit agreement also contains provisions requiring TLC to reimburse its
lenders for increases in certain taxes, revenue requirements and other costs
incurred by the lenders.
    
 
     Loans made under the credit agreement may be prepaid in whole or in part
without premium or penalty, except for reimbursement of the lenders for any
losses the lenders suffer as a result of repayment of LIBOR-based loan prior to
the last day of that applicable interest period.
 
     Events of default under the credit agreement, include, without limitation,
those relating to:
 
     - Non-payment of interest, principal or fees payable under the credit
       agreement.
 
     - Inaccuracy of representations or warranties in the loan documents.
 
     - Non-performance of covenants.
 
   
     - Cross-default to other material debt of TLC and its subsidiaries.
    
 
     - Bankruptcy or insolvency.
 
     - Judgments in excess of specified amounts.
 
     - Certain ERISA events.
 
     - Impairment of security interests in collateral.
 
     - Invalidity of guarantees.
 
     - Materially inaccurate or false representations or warranties.
 
     - A change in control.
 
   
     As a result of the borrowings under the credit agreement, TLC, as well as
C2 on a pro forma basis, will be highly leveraged. C2's pro forma total funded
debt to total capitalization including minority interest at September 30, 1998
was 62% assuming 5,202,664 shares are sold in the C2 offering. In addition, TLC
may, subject to certain restrictions in its debt agreements, incur further
indebtedness from time to time to finance expansion, either through acquisitions
or capital leases, or for other purposes.
    
 
   
     Due to TLC's substantial indebtedness, a significant portion of its cash
flow from operations will be required for debt service.

<PAGE>   108
 
   
     The extent to which TLC is leveraged could have the following consequences:
    
 
   
     - Impairment of TLC's ability to obtain additional financing in the future
       for working capital, capital expenditures, acquisitions or other
       purposes.
    
 
   
     - Dedication of a substantial portion of TLC's cash flow from operations to
       the payment of debt service requirements (principal and interest) on its
       indebtedness.
    
 
   
     - Vulnerability of TLC to changes in general economic conditions.
    
 
   
     - Limitations on TLC's ability to capitalize on significant business
       opportunities and to respond to competition.

            DESCRIPTION OF WEATHERFORD AND CHRISTIANA CAPITAL STOCK
 
WEATHERFORD
 
   
     Weatherford's authorized capital stock consists of 250,000,000 shares of
Weatherford common stock, par value $1.00 per share, and 3,000,000 shares of
Preferred Stock, par value $1.00 per share. At December 22, 1998, 97,452,892
shares of Weatherford common stock were outstanding, including (1) 49,024 shares
of Weatherford common stock remaining to be exchanged for shares of common stock
of GulfMark International, Inc. ("GulfMark") in connection with Weatherford's
prior acquisition of GulfMark, (2) 3,321 shares of Weatherford common stock
remaining to be exchanged for common shares of Taro Industries Limited ("Taro")
in connection with Weatherford's prior acquisition of Taro and (3) 495,581
shares of Weatherford common stock remaining to be exchanged for shares of
common stock of Weatherford Enterra, Inc. in connection with the merger of
Weatherford and Weatherford Enterra, Inc. In addition, at December 22, 1998,
there were (1) 5,031,250 shares of Weatherford common stock reserved for
issuance upon the conversion of Weatherford's 5% Convertible Subordinated
Preferred Equivalent Debentures due 2027, (2) 5,052,000 shares of Weatherford
common stock reserved for issuance pursuant to the proposed merger and (3)
7,900,000 shares of Weatherford common stock reserved for issuance pursuant to
various benefit plans of Weatherford and its subsidiaries, of which 6,013,252
shares of Weatherford common stock were reserved for issuance upon the exercise
of outstanding options and awards. At December 22, 1998, there were no shares of
Weatherford preferred stock issued or outstanding. The holders of shares of
Weatherford common stock are not liable to further calls or assessments by
Weatherford. The description below is a summary of and is qualified in its
entirety by the provisions of Weatherford's Amended and Restated Certificate of
Incorporation, as amended, as currently in effect.
    
 
     Subject to the rights of the holders of any outstanding shares of
Weatherford preferred stock and those rights provided by law, (1) dividends may
be declared and paid or set apart for payment upon the Weatherford common stock
out of any assets or funds of Weatherford legally available for the payment of
dividends and may be payable in cash, stock or otherwise, (2) the holders of
Weatherford stock have the exclusive right to vote for the election of directors
and, except as provided below, on all other matters requiring stockholder action
generally, with each share being entitled to one vote and (3) upon the voluntary
or involuntary liquidation, dissolution or winding up of Weatherford, the net
assets of Weatherford will be distributed pro rata to the holders of the
Weatherford common stock in accordance with their respective rights and
interests to the exclusion of the holders of any outstanding shares of
Weatherford preferred stock.
 
     Although the holders of the Weatherford common stock are generally entitled
to vote for the approval of amendments to Weatherford's Amended and Restated
Certificate of Incorporation, as amended, the voting rights of the holders of
the Weatherford common stock are limited with respect to certain amendments to
Weatherford's Amended and Restated Certificate of Incorporation, as amended,
that affect only the holders of the Weatherford preferred stock. Specifically,
subject to the rights of any outstanding shares of any series of Weatherford
preferred stock, Weatherford's Amended and Restated Certificate of
Incorporation, as amended, provides that it may be amended from time to time in
any manner that would solely modify or change the relative powers, preferences
and rights and the qualifications or restrictions of any issued shares of any
series of Weatherford preferred stock then outstanding with the only required
vote or consent for approval of such amendment being the affirmative vote or
consent of the holders of a majority of the outstanding shares of the series of
Weatherford preferred stock so affected, provided that the powers, preferences
and rights and the qualifications and limitations or restrictions of such series
after giving effect to such amendment are no greater than the powers,
preferences and rights and qualifications and limitations or restrictions
permitted to be fixed and determined by the Board of Directors with respect to
the establishment of any new series of shares of Weatherford preferred stock
pursuant to the authority vested in the Board of Directors as to such matters.
 
     Holders of the Weatherford common stock do not have any cumulative voting,
redemptive or conversion rights and have no preemptive rights to subscribe for,
purchase or receive any class of shares or securities of Weatherford. Holders of
the Weatherford common stock have no fixed dividend rights.
 
                                       106
<PAGE>   110
 
Dividends may be declared by the Board of Directors at its discretion depending
on various factors, although no dividends are anticipated for the foreseeable
future.
 
     The Weatherford preferred stock may be issued from time to time in one or
more series, with each such series having such powers, preferences and rights
and qualifications and limitations or restrictions as may be fixed by
Weatherford's Board of Directors pursuant to the resolution or resolutions
providing for the issuance of such series.
 
     Under Delaware law, a corporation may include provisions in its certificate
of incorporation that will relieve its directors of monetary liability for
breaches of their fiduciary duty to the corporation, except under certain
circumstances, including a breach of the director's duty of loyalty, acts or
omissions of the director not in good faith or which involve intentional
misconduct or a knowing violation of law, the approval of an improper payment of
a dividend or an improper purchase by Weatherford of stock or any transaction
from which the director derived an improper personal benefit. Weatherford's
Amended and Restated Certificate of Incorporation, as amended, provides that
Weatherford's directors are not liable to Weatherford or its stockholders for
monetary damages for breach of their fiduciary duty, subject to the above
described exceptions specified by Delaware law.
 
     As a Delaware corporation, Weatherford is subject to Section 203 of the
Delaware General Corporation Law (the "DGCL"). In general, Section 203 prevents
an "interested stockholder" (defined generally as a person owning 15% or more of
a corporation's outstanding voting stock) from engaging in a "business
combination" (as defined) with a Delaware corporation for three years following
the time such person became an interested stockholder unless (1) before such
person became an interested stockholder, the board of directors of the
corporation approved the transaction in which the interested stockholder became
an interested stockholder or approved the business combination; (2) upon
consummation of the transaction that resulted in the stockholder becoming an
interested stockholder, the interested stockholder owns at least 85% of the
voting stock of the corporation outstanding at the time the transaction
commenced (excluding stock held by directors who are also officers of the
corporation and by employee stock plans that do not provide employees with the
rights to determine confidentially whether shares held subject to the plan will
be tendered in a tender or exchange offer); or (3) following the transaction in
which such person became an interested stockholder, the business combination is
approved by the board of directors of the corporation and authorized at a
meeting of stockholders by the affirmative vote of the holders of two-thirds of
the outstanding voting stock of the corporation not owned by the interested
stockholder. Under Section 203, the restrictions described above also do not
apply to certain business combinations proposed by an interested stockholder
following the announcement or notification of one of certain extraordinary
transactions involving the corporation and a person who had not been an
interested stockholder during the previous three years or who became an
interested stockholder with the approval of a majority of the corporation's
directors, if such extraordinary transaction is approved or not opposed by a
majority of the directors who were directors prior to any person becoming an
interested stockholder during the previous three years or were recommended for
election or elected to succeed such directors by a majority of such directors.
Weatherford has approved the acquisition by Christiana of the shares of
Weatherford common stock owned by them under Section 203 and Christiana are
therefore not subject to the restrictions under Section 203.
 
     The Registrar and Transfer Agent for the Weatherford common stock is
American Stock Transfer and Trust Company, New York, New York.
 
CHRISTIANA
 
     Authorized Capital Stock. The aggregate number of shares of Christiana
capital stock which Christiana has authority to issue is 13,000,000, consisting
of one class, designated as "Common Stock", with a par value of $1.00 per share
and 1,000,000 shares of a class designated as Preferred Stock, with a par value
of $10.00 per share. As of September 30, 1998 there were 5,149,330 shares of
Christiana common stock issued and outstanding. Based on certain commitments by
officers of Christiana to exercise options and purchase shares of Christiana
common stock, as of the closing of the merger, Christiana
 
                                       107
<PAGE>   111
 
expects that there will be 5,149,330 shares of Christiana common stock issued
and outstanding. There are no shares of preferred stock outstanding and the
Board of Directors of Christiana has not fixed any powers, preferences or rights
with respect to any Preferred Stock.
 
     Dividend and Liquidation Rights. All shares of Christiana common stock will
participate equally with respect to dividends and rank equally upon liquidation
subject to the rights of holders of any prior ranking stock which may be
subsequently authorized and issued. In the event of liquidation, dissolution or
winding up of Christiana, the owners of Christiana common stock are entitled to
receive pro rata the assets and funds of Christiana remaining after satisfaction
of all creditors of Christiana and payment of all amounts to which owners of
prior ranking stock, if any, then outstanding may be entitled.
 
     Voting Rights. Except as hereinafter set forth, every holder of Christiana
common stock has one vote for each share.
 
     No shareholder of Christiana has cumulative voting rights which means that
the holders of shares entitled to exercise more than 50% of the voting power of
shares entitled to vote, represented in person or by proxy at a meeting at which
a quorum (a majority of the shares entitled to vote) is represented, are
entitled to elect all of the directors to be elected. Under Christiana's Bylaws,
each member of the Board of Directors is elected each year at Christiana's
annual meeting.
 
     Certain Statutory Provisions. Section 180.1150 of the WBCL provides that
the voting power of shares of an "issuing public corporation", which includes
Christiana, which are held by any person holding in excess of 20% of the voting
power in the election of directors of the issuing public corporation's shares
shall be limited to 10% of the full voting power of such excess shares. This
statutory voting restriction will not be applicable to shares acquired directly
from Christiana, to shares acquired in a transaction incident to which
shareholders of Christiana vote to restore the full voting power of such shares
(either before or after the acquisition of the shares) and under certain other
circumstances.
 
     Except as may otherwise be provided by law, the requisite affirmative vote
of shareholders for certain significant corporate actions, including a merger or
share exchange with another corporation, sale of all or substantially all of the
corporate property and assets, or voluntary liquidation, is a majority of all
the votes entitled to be cast on the transaction by each voting group of
outstanding shares entitled to vote thereon. Sections 180.1130 through 180.1134
of the WBCL provide generally that, in addition to the vote otherwise required
by law or the articles of incorporation of an "issuing public corporation",
certain business combinations not meeting certain adequacy-of-price standards
specified in the statute must be approved by (1) the holders of at least 80% of
the votes entitled to be cast and (2) two-thirds of the votes entitled to be
cast by the corporation's outstanding voting shares owned by persons other than
a "significant shareholder" who is a party to the transaction or an affiliate or
associate thereof. Section 180.1130 defines "business combination" to include,
subject to certain exceptions, a merger or share exchange of the issuing public
corporation (or any subsidiary thereof) with, or the sale or other disposition
of substantially all assets of the issuing public corporation to, any
significant shareholder or affiliate thereof. "Significant shareholder" is
defined generally to mean a person that is the beneficial owner of 10% or more
of the voting power of the outstanding voting shares of the issuing public
corporation.
 
     Pursuant to the requirements of Sections 180.1130 through 180.1134 of the
WBCL, the Lubar Shares will not be counted for purposes of obtaining the
affirmative vote of two-thirds of the outstanding voting shares of Christiana
common stock required to approve the merger.
 
     Sections 180.1140 through 180.1145 of the WBCL provide that a "resident
domestic corporation", such as Christiana, may not engage in a "business
combination" with an "interested stockholder" (e.g., a person beneficially
owning 10% or more of the aggregate voting power of the stock of such
corporation) within three years after the date (the "stock acquisition date") on
which the interested stockholder acquired his or her 10% or greater interest,
unless the business combination (or the acquisition of the 10% or greater
interest) was approved before the stock acquisition date by the corporation's
board of directors. If the interested stockholder fails to obtain such approval
by the board of directors, then even after such three-year period, a business
combination with the interested stockholder may be consummated only with
 
                                       108
<PAGE>   112
 
the approval of the holders of a majority of the voting stock not beneficially
owned by such interested stockholder, unless the combination satisfies certain
adequacy-of-price standards intended to provide a fair price for shares held by
non-interested shareholders.
 
     The above sections of the WBCL could have the effect, among others, of
discouraging takeover proposals for Christiana or impeding a business
combination between Christiana and a major shareholder of Christiana.
 
     Preemptive Rights. No holder of Christiana common stock has any preemptive
or subscription rights.
 
     Conversion Rights, Redemption Provisions and Sinking Fund
Provisions. Christiana common stock is not convertible, is not redeemable and
has no sinking fund.
 
     Liability to Further Calls or to Assessment. Certain statutory personal
liability may be imposed upon shareholders of Wisconsin corporations, including
Christiana, under Section 180.0622(2)(b) of the WBCL. The substantially
identical predecessor to such statute has been judicially interpreted to mean
that shareholders of a Wisconsin corporation are subject to personal liability,
up to an amount equal to the consideration for which their shares were issued
(instead of the aggregate par value in the case of shares with par value, as the
statute states), for all debts owing to employees of the corporation for
services performed for the corporation, but not exceeding six months service in
any one case. The provisions of this Section of the WBCL are presently
applicable to the shares of capital stock of Christiana.
 
        COMPARATIVE RIGHTS OF STOCKHOLDERS OF WEATHERFORD AND CHRISTIANA
 
     The rights of holders of Christiana common stock are currently governed by
Wisconsin law, Christiana's Articles of Incorporation, as amended, and
Christiana's By-laws, as amended. Upon consummation of the merger, holders of
Christiana common stock will become holders of Weatherford common stock and
their rights as holders of Weatherford common stock will be governed by Delaware
law and Weatherford's Amended and Restated Certificate of Incorporation, as
amended, and Weatherford's Amended and Restated By-laws. Set forth below is a
summary of material differences between the rights of holders of Christiana
common stock and rights of holders of Weatherford common stock.
 
SPECIAL VOTE REQUIRED FOR CERTAIN COMBINATIONS
 
     Section 203 of the DGCL applies to Weatherford. Although Weatherford is
subject to Section 203, the merger with Christiana is not prohibited by Section
203.
 
     Except as may otherwise be provided by law, the WBCL provides that the
requisite affirmative vote of shareholders for certain significant corporate
actions, including a merger or share exchange with another corporation, sale of
all or substantially all of the corporate property and assets, or voluntary
liquidation, is a majority of all the votes entitled to be cast on the
transaction by each voting group of outstanding shares entitled to vote thereon.
Section 180.1131 of the WBCL provides generally that, in addition to the vote
otherwise required by law or the articles of incorporation of an "issuing public
corporation", certain business combinations not meeting certain
adequacy-of-price standards specified in the statute must be approved by (1) the
holders of at least 80% of the votes entitled to be cast and (2) two-thirds of
the votes entitled to be cast by the corporation's outstanding voting shares
owned by persons other than a "significant shareholder" who is a party to the
transaction or an affiliate or associate thereof. Section 180.1130 defines
"business combination" to include, subject to certain exceptions, a merger or
share exchange of the issuing public corporation (or any subsidiary thereof)
with, or the sale or other disposition of substantially all assets of the
issuing public corporation to, any significant shareholder or affiliate thereof.
"Significant shareholder" is defined generally to mean a person that is the
beneficial owner of 10% or more of the voting power of the outstanding voting
shares of the issuing public corporation. Although Christiana believes that
Sections 180.1130 through 180.1134 of the WBCL are not intended to apply to
transactions such as the merger, Christiana will require the shareholder vote
required under Section 180.1131 under the assumption that such Section applies
to the merger.
 
                                       109
<PAGE>   113
 
VOTE REQUIRED FOR CORPORATE TRANSACTIONS AND OTHER MATTERS
 
     Under the DGCL, an amendment to a corporation's certificate of
incorporation requires the affirmative vote of the holders of a majority of the
outstanding stock of the corporation entitled to vote thereon and a majority of
the outstanding stock of each class entitled to vote thereon as a class unless
the corporation's certificate of incorporation provides for a higher percentage.
The DGCL also provides that the holders of a majority of the outstanding stock
of the corporation entitled to vote thereon may approve an agreement of merger
or consolidation or the dissolution of a corporation.
 
     The WBCL generally requires the approval of a majority of the votes
entitled to be cast on the amendment by each voting group with respect to which
the amendment would create dissenters' rights and a majority of votes of every
other voting group entitled to vote on the amendment, unless the articles of
incorporation, bylaws adopted under authority granted in the articles of
incorporation or the WBCL require a greater proportion. The WBCL also provides
generally that holders of a majority of outstanding stock of a corporation
entitled to vote thereon may approve an agreement of merger, consolidation or
the dissolution of a corporation, subject to the statutory provisions described
above under "-- Special Vote Required for Certain Combinations" and "Description
of Weatherford and Christiana Capital Stock -- Christiana".
 
     Article 8 of Weatherford's Amended and Restated Certificate of
Incorporation, as amended, provides that the Amended and Restated Certificate of
Incorporation, as amended, may be amended, altered, changed or repealed as
prescribed by statute. Under the DGCL, such amendment must be approved by a
majority of the outstanding Weatherford common stock. Under Article 4 of
Weatherford's Amended and Restated Certificate of Incorporation, as amended, any
amendment to the Amended and Restated Certificate of Incorporation, as amended,
that affects any series of outstanding preferred stock must be approved by a
majority of the holders of such series. The DGCL does not require a vote of the
Weatherford stockholders for the consummation of the merger.
 
     Christiana's Articles of Incorporation, as amended, are silent as to
amendments to the Articles of Incorporation, as amended, and the vote required
to approve mergers and other material corporate transactions.
 
DISPOSITION OF ASSETS
 
     The DGCL provides that a corporation may sell, lease or exchange all or
substantially all of its property and assets for such consideration as its Board
of Directors deems expedient and in the best interest of the corporation, when
and as authorized by resolution adopted by the holders of a majority of the
outstanding stock of the corporation entitled to vote thereon.
 
     Under the WBCL, a corporation may sell, lease, exchange or otherwise
dispose of all, or substantially all, of its property and assets otherwise than
in the usual and regular course of business on such terms and conditions and for
the consideration determined by the corporation's Board of Directors, upon
adoption of a resolution by the Board of Directors approving the proposed
transaction and approval by the majority of all the votes entitled to be cast on
the transactions by the shareholders of the corporation.
 
POWER TO AMEND BY-LAWS
 
     Under the DGCL, the power to adopt, amend or repeal by-laws of a
corporation is vested in the authority of the stockholders entitled to vote,
unless the corporation's certificate of incorporation confers such power upon
its directors. However, power conferred shall not divest the stockholders of
their power to adopt, amend or repeal the by-laws. Weatherford's Amended and
Restated By-laws permit amendments by its board of directors and require an 80%
vote of stockholders to amend the Amended and Restated By-laws.
 
     Under the WBCL, the power to adopt, amend or repeal by-laws of a
corporation is vested in the authority of the board of directors of the
corporation, unless the articles of incorporation provide otherwise. However,
the corporation's stockholders may adopt, amend or repeal by-laws even though
the board of
 
                                       110
<PAGE>   114
 
directors has this power as well. Christiana's articles of incorporation do not
divest the directors of their power to adopt, amend and repeal by-laws.
 
QUORUM REQUIREMENTS FOR DIRECTORS' MEETINGS
 
     The DGCL provides that a majority of the total number of directors shall
constitute a quorum for the transaction of business, unless the certificate of
incorporation or by-laws require a greater number. Weatherford's Amended and
Restated By-laws provide that a majority of the total number of directors shall
constitute a quorum for the transaction of business.
 
     The WBCL provides that a majority of the total number of directors shall
constitute a quorum for the transaction of business, unless the articles of
incorporation or by-laws provide for a greater or lesser number, provided that a
quorum may not be fewer than one-third of the number of directors. Christiana's
By-laws provide that a quorum of the board of directors consists of any four
directors of the eight member board of directors.
 
REMOVAL OF DIRECTORS
 
     The DGCL and Weatherford's Amended and Restated By-laws provide that
directors may be removed, with or without cause, by the holders of a majority of
the shares then entitled to vote at an election of directors. In addition,
Weatherford's Amended and Restated By-laws provide that directors may be
removed, to the extent permitted by law, for cause by vote of the majority of
the directors then in office. A director may be removed for cause only after
reasonable notice and opportunity to be heard before the body proposing to
remove him. The WBCL provides that directors may be removed with or without
cause, unless the articles of incorporation or by-laws provide that directors
may be removed only for cause. Shareholders may remove a director if the number
of shareholder votes cast to remove the director exceeds the numbers of
shareholder votes cast not to remove such director, unless the articles of
incorporation or by-laws provide for a greater voting requirement. Neither
Christiana's Articles of Incorporation, as amended, nor its By-laws expressly
addresses the removal of directors.
 
DIRECTOR ELECTIONS, QUALIFICATIONS AND NUMBER
 
     The DGCL provides that the number of directors of a Delaware corporation
shall be fixed by, or in the manner provided in, the by-laws, unless the
certificate of incorporation fixes such number, in which case, it can only be
changed by amending the certificate of incorporation. Under the DGCL, a director
need not be a stockholder to be qualified unless so required by the
corporation's certificate of incorporation or by-laws. Weatherford's Amended and
Restated By-laws provide that directors are to be elected by a plurality vote of
the stockholders; provided, however, that any vacancies occurring in the board
may be filled by the remaining directors.
 
     The WBCL provides that the number of directors of a Wisconsin corporation
shall be fixed in accordance with the articles of incorporation or by-laws.
Under the WBCL, a director need not be a stockholder to be qualified unless so
required by the corporation's articles of incorporation or by-laws. Under the
WBCL, unless otherwise provided by the articles of incorporation, directors are
to be elected by a plurality of votes cast by the shares entitled to vote in the
election; provided, however, that a vacancy on the board may be filled by the
shareholders or the board of directors. Christiana's Articles of Incorporation,
as amended, are silent with respect to the qualifications and election of
directors.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors and Shareholders
of Christiana Companies, Inc.:
 
     We have audited the accompanying consolidated balance sheets of Christiana
Companies, Inc. (a Wisconsin corporation) and subsidiary as of June 30, 1998 and
1997, and the related consolidated statements of earnings, shareholders' equity
and cash flows for each of the years in the three year period ended June 30,
1998. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Christiana Companies, Inc. as of June 30, 1998 and 1997, and the results of
their consolidated operations and their cash flows for each of the three years
in the period ended June 30, 1998, in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                       (THREE YEARS ENDED JUNE 30, 1997)
 
A. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
     Description of Business: At June 30, 1998, Christiana is engaged in
providing public refrigerated and dry (non-refrigerated) warehousing and
logistic services; and owning 3,897,462 shares of Weatherford International,
Inc. common stock which represents an approximate 4% ownership interest.
 
     Revenue Recognition: Transportation revenue is recognized when the goods
are delivered to the customer. Warehousing revenue is recognized as services are
provided. Costs and related expenses are recorded as incurred.
 
     Principles of Consolidation: The consolidated financial statements include
the accounts of Christiana Companies, Inc., ("Christiana") and its wholly-owned
subsidiary (together with Christiana referred to as the "Company"). All material
intercompany transactions have been eliminated in consolidation.
 
     Use of Estimates: The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
     Short-Term Investments: Short-term investments consist of U.S. Treasury
securities and commercial paper maturing in less than one year. These
investments are carried at amortized cost, which approximates fair value.
 
     Accounts Receivable: Accounts receivable are presented net of a reserve for
bad debts of $222,000 and $333,000 at June 30, 1998 and 1997, respectively. The
provision for bad debts was $119,000, $227,000 and $123,000 for the years ended
June 30, 1998, 1997 and 1996, respectively.
 
     Inventories: Inventories consist predominately of transportation equipment
repair parts. These items are carried at their lower of FIFO (first-in,
first-out) cost or market value.
 
     Investment in Weatherford International, Inc.: Prior to May 27, 1998, the
Company accounted for its investment in Weatherford under the equity method. As
such, the Company's proportionate share of Weatherford earnings through May 27,
1998, is recorded in the statement of earnings as "Equity in Earnings of
Weatherford International, Inc." On May 27, 1998, Weatherford acquired
Weatherford Enterra, Inc. issuing additional shares of common stock which
reduced the Company's ownership percentage to approximately 4%. As a result of
this reduction in ownership, the Company no longer accounts for this investment
under the equity method; but rather accounts for its investment in Weatherford
using the cost method. Under the cost method, only dividends paid by Weatherford
will be reflected in future earnings of the Company.
 
     The Company has classified its investment in Weatherford as "available-for
sale." Accordingly, the Weatherford shares owned by the Company (3,897,462
shares as of June 30, 1998) are recorded at their fair market value on the
balance sheet. Unrealized gains, net of deferred taxes, in the amount of
$57,799,000, are reflected as an increase to Shareholders' Equity.
 
     Mortgage Notes Receivable: At June 30, 1998, mortgage notes receivable,
derived from condominium sales, totaled $532,000 and accrue interest at rates
ranging from 7.250% to 8.500%.
 
     The principal balance of mortgage notes receivable matures as follows:

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     During the years ended June 30, 1998 and 1997, mortgage notes receivable of
$1,170,000 and $1,882,000, respectively, were sold or prepaid.
 
     Fixed Assets: Fixed assets are carried at cost less accumulated
depreciation, which is computed using both straight-line and accelerated methods
for financial reporting purposes. The cost of major renewals and improvements
are capitalized; repair and maintenance costs are expensed as incurred. A
summary of the cost of fixed assets and the estimated useful lives for financial
reporting purposes is as follows:

</TABLE>
 
     Goodwill: Goodwill is amortized on a straight-line basis over 40 years
($157,000 in 1998, 1997 and 1996). The accumulated amortization at June 30, 1998
and 1997 was $723,000 and $566,000, respectively. The Company continually
evaluates whether events and circumstances have occurred that indicate the
remaining estimated useful life may warrant revision or that the remaining
balance of goodwill may not be recoverable. When factors indicate that goodwill
should be evaluated for possible impairment, the Company uses an estimate of
undiscounted cash flows over the remaining life of the goodwill measuring
whether the goodwill is impaired. If impaired, a loss is recognized for the
amount that the carrying value exceeds the fair value.
 
     Long-Lived Assets: During fiscal 1997, the Company adopted Statement of
Financial Accounting Standards ("SFAS") No. 121, "Accounting for the Impairment
of Long-lived Assets and Assets to be Disposed of." Adoption of this standard
did not have a material impact on the Company's financial position or results of
operations. The Company continually evaluates whether events and circumstances
have occurred that may indicate the remaining estimated useful life may warrant
revision or that the remaining balance of long-lived assets may be not
recoverable. When factors indicate that long-lived assets should be evaluated
for possible impairment, the Company uses an estimate of the undiscounted cash
flows over the remaining life of the long-lived assets measuring whether these
assets are impaired. If impaired, a loss is recognized for the amount that the
carrying value exceeds the fair value.
 
     Other Assets: Other Assets primarily represent deferred charges and cash
surrender value of officer's life insurance.
 
     Income Taxes: Deferred income taxes are provided on the temporary
differences in the carrying values of assets and liabilities for financial
reporting and income tax purposes.
 
     Cash and Cash Equivalents: The Company considers all highly liquid
investments with original maturities of less than ninety days to be cash
equivalents.
 
     Reclassifications: Certain reclassifications have been made in the 1997
statements to conform with 1998 presentation.

B. WEATHERFORD INTERNATIONAL, INC. MERGER AGREEMENT:
 
     On December 12, 1997, the Company entered into an agreement with
Weatherford International, Inc. ("Weatherford") whereby Weatherford will
purchase all of the outstanding shares of the Company. The terms of the merger
provide that each Christiana common share will be converted into (i) .7453
shares of Weatherford International, Inc. common stock, (ii) cash in the
approximate amount of $4.00, depending upon the balance of certain assets and
liabilities at the time of closing and (iii) a contingent cash payment of
approximately $1.92 after 5 years, subject to the incurrence of any indemnity
claims by Weatherford during this period.
 
   
     On August 17, 1998, the shareholders of both Weatherford and Christiana
overwhelmingly approved the Merger agreement and sale of Total Logistic Control
to C2, Inc. However, due to the recent decline in the value of Weatherford's
common stock price, the merger transaction was postponed until the conditions
are met for Christiana's shareholders to not recognize any taxable gain or loss
on their exchange of Christiana shares for Weatherford common stock in the
merger. To meet this requirement, Weatherford's stock price must be
approximately $30.00 per share. As of September 23, 1998, the fair market value
of this investment decreased from $144.2 million at June 30, 1998 to
approximately $97.4 million as a result of market fluctuations.
    
 
     By its terms, the Merger Agreement may be terminated by either party after
October 31, 1998. Currently, both Christiana and Weatherford are monitoring
Weatherford's stock price and will close the merger on or prior to October 31,
1998, if it exceeds $30.00 per share and all other requirements remain
satisfied.
 
     As of June 30, 1998, the Company has deferred approximately $773,000 of
transaction costs related to the merger. If the merger is not completed, these
costs will be charged to earnings during fiscal 1999 at the time of termination.
Total merger related costs that would ultimately be charged to earnings,
including those amounts deferred at June 30, 1998, are estimated at
approximately $1.8 million.

     Pro forma information regarding net income and earnings per share is
required by Statement of Financial Accounting Standards No. 123 and has been
determined as if the Company had accounted for its stock options under the fair
value method as provided therein. The fair value of each option is estimated on
the date of the grant using an option pricing model with the following
weighted-average assumptions used for options issued in fiscal 1997 and 1996,
respectively: risk-free interest rate of 6.5%; expected remaining lives of 5 and
6 years; expected volatility of 25% and 20%; and no expected dividends.
 
     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. Set forth
below is a summary of the Company's net earnings and earnings per share as
reported and pro forma, as if the fair value based method of accounting defined
in SFAS No. 123 had been applied. The pro forma information is not meant to be

              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
 
NOTE 1 -- ACCOUNTING POLICIES
 
     The accompanying unaudited financial statements reflect all adjustments
which are, in the opinion of management, necessary to present fairly the results
for the interim periods presented and should be read in conjunction with the
Company's 1998 Annual Report on Form 10-K.
 
NOTE 2 -- INVESTMENT IN WEATHERFORD INTERNATIONAL, INC.
 
     Prior to May 27, 1998, the Company accounted for its investment in
Weatherford under the equity method. As such, the Company's proportionate share
of Weatherford earnings through May 27, 1998, is recorded in the statement of
earnings as "Equity in Earnings of Weatherford." On May 27, 1998, Weatherford
acquired Weatherford Enterra, Inc. issuing additional shares of common stock
which reduced the Company's ownership percentage to approximately 4%. As a
result of this reduction in ownership, the Company no longer accounts for this
investment under the equity method; but rather accounts for its investment in
Weatherford using the cost method. Under the cost method, only dividends paid by
Weatherford will be reflected in future earnings of the Company.
 
     The Company has classified its investment in Weatherford as
"available-for-sale." Accordingly, the Weatherford shares owned by the Company
(3,897,462 shares as of September 30, 1998) are recorded at their fair market
value on the balance sheet. Unrealized gains, net of deferred taxes, in the
amount of $21,365,000, are reflected as an increase to Shareholders' Equity.
 
NOTE 3 -- WEATHERFORD/CHRISTIANA MERGER
 
     On October 14, 1998, Christiana and Weatherford International, Inc.
announced amended merger terms which were designed both to improve the terms for
Christiana shareholders and to increase substantially the likelihood of
completing the merger on a partially tax free basis. The amended terms eliminate
a $10 million contingent holdback that was previously required and commits
Christiana to purchase at least $10 million of Weatherford common stock, plus up
to an additional $5 million of Weatherford share purchases, if necessary, to
allow for the stock consideration in the merger to be received by the Christiana
shareholders to be on a tax-free basis. The cash component in the merger is
anticipated to be between $3.00 and $4.00 per Christiana share depending on if
any of the additional $5 million Weatherford common share purchases are
completed. Completion of the merger, as amended, is subject to various
conditions, including approvals by Weatherford and Christiana shareholders.
 
NOTE 4 -- COMPREHENSIVE INCOME
 
     Effective July 1, 1998, the Company adopted SFAS No. 130, "Reporting
Comprehensive Income." This statement establishes rules for the reporting of
comprehensive income and its components. The Company's comprehensive income
components consist of net income and unrealized gains on securities available
for sale and are presented in the Consolidated Statement of Shareholders'
Equity. For interim reporting, the Company has chosen to disclose comprehensive
income in the notes to financial statements. The components of comprehensive
income for the three months ended September 30, 1998 and 1997 are as follows:

     THIS AMENDED AND RESTATED AGREEMENT AND PLAN OF MERGER dated as of October
14, 1998 (this "Agreement"), is made and entered into by and among WEATHERFORD
INTERNATIONAL, INC. (formerly known as EVI, Inc.), a Delaware corporation
("Weatherford"), CHRISTIANA ACQUISITION, INC., a Wisconsin corporation and
wholly owned subsidiary of Weatherford ("Sub"), CHRISTIANA COMPANIES, INC., a
Wisconsin corporation ("Christiana"), and C2, INC., a Wisconsin corporation
("C2").
 
   
     WHEREAS, Weatherford, Sub, Christiana and C2 entered into an Agreement and
Plan of Merger, dated as of December 12, 1997, and an Amendment No. 1 to
Agreement and Plan of Merger and Logistic Purchase Agreement dated May 26, 1998;
    
 
     WHEREAS, Weatherford, Sub, Christiana and C2 desire to amend and restate
the Agreement and Plan of Merger to provide for additional amendments set forth
herein;
 
     WHEREAS, subject to and in accordance with the terms and conditions of this
Agreement, the respective Boards of Directors of Weatherford, Sub and
Christiana, and Weatherford as sole stockholder of Sub, have approved the merger
of Sub with and into Christiana (the "Merger"), whereby each issued and
outstanding share of common stock, $1.00 par value, of Christiana ("Christiana

defined in Section 1.7(e));
 
   
     WHEREAS, as a condition to the Merger, Christiana will sell to C2

     WHEREAS, immediately after the Effective Time, Christiana will only hold
the Christiana Assets, as such terms are hereinafter defined in Sections 1.3 and
2.2(o);
 
     WHEREAS, for federal income tax purposes, it is intended that the Merger

(the "Code"); and
 
     WHEREAS, the parties hereto desire to set forth certain representations,
warranties and covenants made by each to the other as an inducement to the

hereby agree as follows:
 
                                   ARTICLE I
 
                                   THE MERGER
 
   
     1.1  THE MERGER. Subject to and in accordance with the terms and conditions
of this Agreement and in accordance with the Wisconsin Business Corporation Law
("WBCL"), at the Effective Time (as defined in Section 1.3), Sub shall be merged
with and into Christiana. As a result of the Merger, the separate corporate
existence of Sub shall cease and Christiana shall continue as the surviving
corporation (sometimes referred to herein as the "Surviving Corporation"), and
all the properties, rights, privileges, powers and franchises of Sub and

     1.2  CLOSING DATE. The closing of the transactions contemplated by this
Agreement (the "Closing") shall take place at the offices of Fulbright &
Jaworski L.L.P., Houston, Texas, as soon as practicable after the satisfaction
or waiver of the conditions set forth in Article VI hereof or at such other time
and place and on such other date as Weatherford and Christiana shall agree;
provided that the closing conditions set forth in Article VI hereof shall have
been satisfied or waived at or prior to such time. The date on which the Closing
occurs is herein referred to as the "Closing Date".
 
     1.3  CONSUMMATION OF THE MERGER. As soon as practicable on the Closing
Date, the parties hereto will cause the Merger to be consummated by filing with
the Department of Financial Institutions of the State of Wisconsin the Articles
of Merger in such form as required by, and executed in accordance with, the
relevant provisions of the WBCL. The "Effective Time" of the Merger, as that
term is used in this Agreement, shall mean such time as the Articles of Merger
are duly filed with the Department of Financial Institutions of the State of
Wisconsin or at such later time (not to exceed seven days from the date the
Articles of Merger are filed) as is specified in the Articles of Merger pursuant
to the mutual agreement of Weatherford and Christiana.
 
     1.4  EFFECTS OF THE MERGER. The Merger shall have the effects set forth in
the applicable provisions of the WBCL. If at any time after the Effective Time
of the Merger, the Surviving Corporation shall consider or be advised that any
further assignments or assurances in law or otherwise are necessary or desirable
to vest, perfect or confirm, of record or otherwise, in the Surviving
Corporation, all rights, title and interests in all real estate and other
property and all privileges, powers and franchises of Christiana and Sub, the
Surviving Corporation and its proper officers and directors, in the name and on
behalf of Christiana and Sub, shall execute and deliver all such proper deeds,
assignments and assurances in law and do all things necessary and proper to
vest, perfect or confirm title to such property or rights in the Surviving
Corporation and otherwise to carry out the purpose of this Agreement, and the
proper officers and directors of the Surviving Corporation are fully authorized
in the name of Christiana or otherwise to take any and all such action.
 
     1.5  ARTICLES OF INCORPORATION; BYLAWS. The Articles of Incorporation of
Christiana, as amended and restated by the amendment set forth in Exhibit B
attached hereto, shall be the Articles of Incorporation of the Surviving
Corporation and thereafter shall continue to be its Articles of Incorporation
until amended as provided therein or under the WBCL. The bylaws of Sub, as in
effect immediately prior to the Effective Time, shall be the bylaws of the
Surviving Corporation and thereafter shall continue to be its bylaws until
amended as provided therein or under the WBCL.
 
     1.6  DIRECTORS AND OFFICERS. The directors of Sub immediately prior to the
Effective Time shall be the directors of the Surviving Corporation at and after
the Effective Time, each to hold office in accordance with the Articles of
Incorporation and bylaws of the Surviving Corporation, and the officers of Sub
immediately prior to the Effective Time shall be the officers of the Surviving
Corporation at and after the Effective Time, in each case until the earlier of
their resignation or removal or their respective successors are duly elected or
appointed and qualified.
 
     1.7  CONVERSION OF SECURITIES. Subject to the terms and conditions of this
Agreement, at the Effective Time, by virtue of the Merger and without any
further action on the part of Weatherford, Christiana, Sub or their
stockholders:
 
          (a) Subject to adjustments pursuant to Section 1.7(e) hereof, each
     share of Christiana Common Stock issued and outstanding immediately prior
     to the Effective Time (the "Christiana Shares") shall be converted into the
     right to receive (i) a fraction of a share of Weatherford Common Stock
     equal to the number of shares of Weatherford Common Stock held by
     Christiana at the Effective Time divided by the number of shares of
     Christiana Common Stock outstanding immediately prior to the Effective Time
     (the "Stock Exchange Ratio") plus (ii) the Cash Consideration Per Share as
     defined in Section 1.7(e); provided, however, that no fractional shares of
     Weatherford Common Stock shall be issued and, in lieu thereof, all
     fractional shares of Weatherford Common Stock that would otherwise be
     issuable in the Merger shall be rounded to the nearest whole share of
     Weatherford Common Stock. Except as set forth in the preceding sentence
     with respect to the Cash Consideration Per Share, no other consideration
     will be paid to the Christiana stockholders.
                                       A-4
<PAGE>   147
 
          (b) Each Christiana Share owned directly or indirectly by Christiana
     as treasury stock and each Christiana Share owned by Sub, Weatherford or
     any direct or indirect wholly-owned subsidiary of Weatherford or of
     Christiana immediately prior to the Effective Time shall be canceled and
     extinguished without any conversion thereof and no payment or other
     consideration shall be made or paid with respect thereto.
 
          (c) Each share of common stock, $1.00 par value, of Sub issued and
     outstanding immediately prior to the Effective Time shall be converted into
     one fully paid and nonassessable share of common stock, $1.00 par value, of
     the Surviving Corporation.
 
          (d) [Intentionally Omitted]
 
          (e) The "Cash Consideration Per Share", shall equal the quotient of
     the Christiana Net Cash divided by 5,149,330. The "Christiana Net Cash"
     shall mean and be equal to all cash on hand of Christiana at the Closing
     minus (ii) an amount of cash necessary to pay the Christiana Liabilities in
     full without giving effect to the use or application of any tax deductions
     relating to the exercise of options or any tax benefits that may be
     realized as a result of amended Tax Returns. The "Cash Consideration Per
     Share" is based on 5,149,330 shares of Christiana Common Stock being issued
     and outstanding immediately prior to the Effective Time. In the event the
     number of shares of Christiana Common Stock outstanding immediately prior
     to the Effective Time is greater or less than 5,149,330, the Cash
     Consideration Per Share shall be adjusted to equal the quotient of the
     Christiana Net Cash divided by the number of shares of Christiana Common
     Stock issued and outstanding immediately prior to the Effective Time.
 
1.8  EXCHANGE OF CERTIFICATES.
 
          (a) Exchange Agent. Prior to the Effective Time of the Merger,
     Weatherford shall select a bank or trust company to act as exchange agent
     (the "Exchange Agent") for the issue of shares of Weatherford Common Stock
     upon surrender of certificates representing Christiana Shares.
 
          (b) Payment of Merger Consideration. Weatherford shall take all steps
     necessary to enable and cause there to be provided to the Exchange Agent on
     a timely basis, as and when needed after the Effective Time of the Merger,
     certificates for the shares of Weatherford Common Stock to be issued upon
     the conversion of the Christiana Shares pursuant to Section 1.7 and the
     cash necessary to be issued for the Cash Consideration Per Share.
 
          (c) Retention of Cash Pending Post Closing Audit. Within 30 days
     following the Effective Date, Weatherford shall (i) complete a post closing
     audit by Weatherford of the Christiana Net Cash and (ii) pay to the
     Exchange Agent on behalf of the holders of the Christiana Shares the Cash
     Consideration Per Share in respect of such Christiana Shares subject to the
     prior presentation of the certificates that immediately prior to the
     Effective Time represented the outstanding Christiana Shares (the
     "Certificates").
 
          (d) [Intentionally Omitted]
 
          (e) Exchange Procedure. As soon as reasonably practical after the
     Effective Time of the Merger, the Exchange Agent shall mail to each holder
     of record of a Certificate or Certificates, other than Weatherford, Sub and
     Christiana and any directly or indirectly wholly owned subsidiary of
     Weatherford, Sub or Christiana, (i) a letter of transmittal (which shall
     specify that delivery shall be effected, and risk of loss and title to the
     Certificates shall pass, only upon delivery of the Certificates to the
     Exchange Agent and shall be in a form and have such other provisions as
     Weatherford and Sub may reasonably specify) and (ii) instructions for use
     in effecting the surrender of the Certificates in exchange for the
     certificates representing the shares of Weatherford Common Stock and the
     Cash Consideration Per Share. Upon surrender of a Certificate for
     cancellation to the Exchange Agent or to such other agent or agents as may
     be appointed by the Surviving Corporation, together with such letter of
     transmittal, duly executed, and such other documents as may reasonably be
     required by the Exchange Agent, the holder of such Certificate shall be
     entitled to receive in exchange therefor a certificate or certificates
     representing the number of whole shares of Weatherford Common Stock into
     which the Christiana Shares theretofore represented by such Certificate
     shall have been converted pursuant to Section 1.7 and the Cash
 
                                       A-5
<PAGE>   148
 
     Consideration Per Share as provided in Section 1.8(c), and the Certificate
     so surrendered shall forthwith be canceled. If the shares of Weatherford
     Common Stock are to be issued to an individual, corporation, limited
     liability company, partnership, governmental authority or any other entity
     (a "Person"), other than the person in whose name the Certificate so
     surrendered is registered, it shall be a condition of exchange that such
     Certificate shall be properly endorsed or otherwise in proper form for
     transfer and that the Person requesting such exchange shall pay any
     transfer or other taxes required by reason of the exchange to a Person
     other than the registered holder of such Certificate or establish to the
     satisfaction of the Surviving Corporation that such tax has been paid or is
     not applicable. Until surrendered as contemplated by this Section 1.8, each
     Certificate shall be deemed at any time after the Effective Time of the
     Merger to represent only the right to receive upon such surrender the
     number of shares of Weatherford Common Stock and the Cash Consideration Per
     Share payable in respect of the Christiana Shares pursuant to Section 1.7.
     The Exchange Agent shall not be entitled to vote or exercise any rights of
     ownership with respect to the shares of Weatherford Common Stock held by it
     from time to time hereunder, except that it shall receive and hold all
     dividends or other distributions paid or distributed with respect thereto
     for the account of Persons entitled thereto. Any unexchanged shares of
     Weatherford Common Stock issuable pursuant to the Merger in respect of the
     Christiana Shares shall be issued in the name of the Exchange Agent pending
     the receipt by the Exchange Agent of Certificates.
 
          (f) Distributions with Respect to Unexchanged Christiana Shares. No
     dividends or other distributions declared or made after the Effective Time
     of the Merger with respect to the shares of Weatherford Common Stock with a
     record date after the Effective Time of the Merger shall be paid to the
     holder of any unsurrendered Certificate with respect to the shares of
     Weatherford Common Stock represented thereby and the Cash Consideration Per
     Share shall not be paid until the holder of record of such Certificate
     shall surrender such Certificate. Subject to the effect of applicable laws,
     following surrender of any such Certificate, there shall be paid to the
     record holder of the Certificates representing the shares of Weatherford
     Common Stock issued in exchange therefor, without interest, (i) the amount
     of dividends or other distributions with a record date after the Effective
     Time of the Merger theretofore paid with respect to such whole shares of
     Weatherford Common Stock, as the case may be, (ii) at the appropriate
     payment date, the amount of dividends or other distributions with a record
     date after the Effective Time of the Merger but prior to surrender and a
     payment date subsequent to surrender payable with respect to such whole
     shares of Weatherford Common Stock and (iii) the Cash Consideration Per
     Share at the appropriate payment date as provided in this Section 1.8.
 
          (g) No Further Ownership Rights in Christiana Shares. All shares of
     Weatherford Common Stock issued upon the surrender of Certificates in
     accordance with the terms of this Article I, together with any dividends
     payable thereon to the extent contemplated by this Section 1.8 and the
     rights to receive the Cash Consideration Per Share as provided herein,
     shall be deemed to have been exchanged and paid in full satisfaction of all
     rights pertaining to the Christiana Shares theretofore represented by such
     Certificates and there shall be no further registration of transfers on the
     stock transfer books of the Surviving Corporation of the Christiana Shares
     that were outstanding immediately prior to the Effective Time of the
     Merger. If, after the Effective Time of the Merger, Certificates are
     presented to the Surviving Corporation for any reason, they shall be
     canceled and exchanged as provided in this Article I.
 
          (h) Escheat. None of Weatherford, Sub, Christiana, the Surviving
     Corporation or their transfer agents shall be liable to a holder of the
     Christiana Shares for any amount properly paid to a public official
     pursuant to applicable property, escheat or similar laws.
 
   
     1.9  TAKING OF NECESSARY ACTION; FURTHER ACTION. The parties hereto shall
take all such reasonable and lawful action as may be necessary or appropriate in
order to effectuate the Merger and the Logistic Sale as promptly as possible.
If, at any time after the Effective Time, any such further action is necessary
or desirable to carry out the purposes of this Agreement or the Logistic Sale,
and to vest the Surviving Corporation with full right, title and possession to
all assets, property, rights, privileges, powers and franchises of Christiana or
Sub as of the Effective Time, such corporations shall direct their respective
officers and directors to take all such lawful and necessary action.

                         REPRESENTATIONS AND WARRANTIES
 
     2.1  REPRESENTATIONS AND WARRANTIES OF WEATHERFORD AND SUB. Weatherford and
Sub hereby jointly and severally represent and warrant to Christiana that:
 
          (a) Organization and Compliance with Law. Weatherford and Sub are
     corporations duly incorporated, validly existing and in good standing under
     the laws of the states of Delaware and Wisconsin, respectively. Each of
     Weatherford and Sub has all requisite corporate power and corporate
     authority to own, lease and operate all of its properties and assets and to
     carry on its business as now being conducted, except where the failure to
     be so organized, existing or in good standing would not have a material
     adverse effect on the financial condition of Weatherford and its
     subsidiaries (the "Weatherford Subsidiaries"), taken as a whole (a
     "Weatherford MAE"). Each of Weatherford and Sub is duly qualified to do
     business, and is in good standing, in each jurisdiction in which the
     property owned, leased or operated by it or the nature of the business
     conducted by it makes such qualification necessary, except in such
     jurisdictions where the failure to be duly qualified would not have a
     Weatherford MAE. Each of Weatherford and Sub is in compliance with all
     applicable laws, judgments, orders, rules and regulations, except where
     such failure would not have a Weatherford MAE. Weatherford has heretofore
     delivered to Christiana true and complete copies of Weatherford's Amended
     and Restated Certificate of Incorporation (the "Weatherford Certificate"),
     and Sub's Articles of Incorporation and their respective bylaws as in
     existence on the date hereof.
 
          (b) Capitalization.
 
             (i) The authorized capital stock of Weatherford consists of
        250,000,000 shares of Weatherford Common Stock, $1.00 par value, and
        3,000,000 shares of preferred stock, $1.00 par value ("Weatherford
        Preferred Stock"). As of July 10, 1998, there were 97,511,967 shares of
        Weatherford Common Stock issued and outstanding. As of July 10, 1998,
        (i) 5,031,250 shares of Weatherford Common Stock were reserved for
        issuance pursuant to the conversion provisions of Weatherford's 5%
        Convertible Subordinated Preferred Equivalent Debentures due 2027, (ii)
        3,900,000 shares of Weatherford Common Stock were reserved for issuance
        pursuant to pending or proposed acquisitions, (iii) 1,577,410 shares of
        Weatherford Common Stock were remaining to be exchanged for shares of
        stock in connection with various completed acquisitions and (iv)
        3,269,376 shares of Weatherford Common Stock were reserved for issuance
        pursuant to Weatherford's employee and director benefit plans and
        arrangements, of which 1,897,704 shares of Weatherford Common Stock were
        reserved for issuance upon exercise of outstanding options. At July 10,
        1998, there were no shares of Weatherford Preferred Stock issued or
        outstanding. No holder of Weatherford Common Stock is entitled to
        preemptive rights under Delaware law or Weatherford's Certificate of
        Incorporation.
 
             (ii) As of the date hereof, the authorized capital stock of Sub
        consists of 1,000 shares of common stock, $1.00 par value, all of which
        are validly issued, fully paid and nonassessable and are owned by
        Weatherford.
 
             (iii) Each share of Weatherford Common Stock to be issued hereunder
        as a result of the Merger will be fully paid and non-assessable upon
        issuance.
 
          (c) Authorization and Validity of Agreement. The execution and
     delivery by Weatherford and Sub of this Agreement and the consummation by
     each of them of the transactions contemplated hereby have been duly
     authorized by all necessary corporate action (subject only, with respect to
     the Merger, to approval of this Agreement by each of their stockholders as
     provided for in Section 5.3). On or prior to the date hereof, the Board of
     Directors of Weatherford or duly authorized committee thereof has
     determined to recommend approval of the Merger to the stockholders of
     Weatherford, and such determination is in effect on the date hereof. This
     Agreement has been duly executed and delivered by Weatherford and Sub and
     is the valid and binding obligation of Weatherford and Sub, enforceable
     against Weatherford and Sub in accordance with its terms.

          (d) No Approvals or Notices Required; No Conflict. Neither the
     execution and delivery of this Agreement nor the performance by Weatherford
     or Sub of its obligations hereunder, nor the consummation of the
     transactions contemplated hereby by Weatherford and Sub, will (i) conflict
     with the Weatherford Certificate or the bylaws of Weatherford or Sub; (ii)

     Weatherford Subsidiaries; (iii) except for (A) requirements of Federal or
     state securities laws, (B) requirements arising out of the
     Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act"), (C)
     requirements of notice filings in such foreign jurisdictions as may be
     applicable, and (D) the filing of Articles of Merger by Sub in accordance
     with the WBCL, require any consent or approval of, or filing with or notice
     to, any public body or authority, domestic or foreign, under any provision
     of law applicable to Weatherford or any of the Weatherford Subsidiaries; or
     (iv) require any consent, approval or notice under, or violate, breach, be
     in conflict with or constitute a default (or an event that, with notice or
     lapse of time or both, would constitute a default) under, or permit the
     termination of any provision of, or result in the creation or imposition of
     any lien, mortgage, pledge, security interest, restriction on transfer,
     option, charge, right of any third Person or any other encumbrance of any
     nature (a "Lien") upon any properties, assets or business of Weatherford or
     any of the Weatherford Subsidiaries under, any note, bond, indenture,
     mortgage, deed of trust, lease, franchise, permit, authorization, license,
     contract, instrument or other agreement or commitment or any order,
     judgment or decree to which Weatherford or any of the Weatherford
     Subsidiaries is a party or by which Weatherford or any of the Weatherford
     Subsidiaries or any of its or their assets or properties is bound or
     encumbered, except (A) those that have already been given, obtained or
     filed and (B) those that, in the aggregate, would not have a Weatherford
     MAE.
 
          (e) Commission Filings; Financial Statements. Weatherford has filed
     all reports and documents required to filed with the Securities and
     Exchange Commission (the "Commission") since December 31, 1995. All
     reports, registration statements and other filings (including all notes,
     exhibits and schedules thereto and documents incorporated by reference
     therein) filed by Weatherford with the Commission since December 31, 1995,
     through the date of this Agreement, together with any amendments thereto,
     are sometimes collectively referred to as the "Weatherford Commission
     Filings". Weatherford has heretofore delivered to, or made accessible to,
     Christiana copies of the Weatherford Commission Filings. As of the
     respective dates of their filing with the Commission, the Weatherford
     Commission Filings complied in all material respects with the applicable
     requirements of the Securities Act of 1934 (the "Securities Act"), the
     Securities Exchange Act of 1934 (the "Exchange Act") and the rules and
     regulations of the Commission thereunder, and did not contain any untrue
     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary to make the statements made therein, in
     light of the circumstances under which they were made, not misleading.
 
          (f) Absence of Certain Charges and Events. Since December 31, 1997,
     except as contemplated by this Agreement or as disclosed in the Weatherford

        established by Weatherford, except where the failure to file, pay or
        provide for would not have a Weatherford MAE.

     state any material fact required to be stated therein or necessary to make
     the statements therein not misleading, and (ii) the Proxy Statement (as

     2.2  REPRESENTATIONS AND WARRANTIES OF CHRISTIANA AND C2. Each of
Christiana and C2 hereby, jointly and severally, represents and warrants to
Weatherford that:

     (or equivalent) power and corporate (or equivalent) authority and all
     necessary governmental authorizations to own, lease and operate all of its
     properties and assets and to carry on its business as now being conducted,
     except where the failure to be so organized, existing or in good standing
     or to have such governmental authority would not (i) have a material
     adverse effect on the financial condition of Christiana or Logistic after
     giving effect to the Logistic Sale or (ii) prevent or adversely affect the
     ability of Christiana and C2 to perform and comply with their respective
     obligations under this Agreement, the Logistic Purchase Agreement or any
     other agreement to be executed and delivered in connection with the
     transactions contemplated hereby or thereby (a "Christiana MAE"). Except as

     Logistic and C2 is duly qualified as a foreign corporation or limited
     liability company to do business, and is in good standing, in each
     jurisdiction in which the property owned, leased or operated by it or the
     nature of the business conducted by it makes such qualification necessary,
     except in such jurisdictions where the failure to be duly qualified does
     not and would not have a Christiana MAE. Each of Christiana, Logistic and
     C2 is in compliance with all applicable laws, judgments, orders, rules and
     regulations, domestic and foreign, except where failure to be in such
     compliance would not have a Christiana MAE. Christiana has heretofore

     Articles of Incorporation (the "Christiana Articles") and bylaws, (ii)
     Logistic's Certificate of Organization and operating agreement and (iii)

        and no holder thereof is entitled to preemptive rights. Christiana is
        not a party to, and is not aware of, any voting agreement, voting trust

             (ii) Christiana owns 100% of the membership interests in Logistic.
        All issued and outstanding membership interests of Logistic are validly
        issued, fully paid and nonassessable and no holder thereof is entitled

        interests of Logistic.
    
 
             (iii) As of the date hereof, there are outstanding options (the

        exercised prior to the Effective Time. As of the Effective Time, there
        will be no options outstanding under the Christiana Option Plan. There
        are not now (other than as set forth in this Section 2.2(b)), and at the
        Effective Time there will not be, any (A) shares of capital stock or
        other equity securities of Christiana issuable pursuant to the exercise
        of Christiana Options or (B) outstanding options, warrants, scrip,
        rights to subscribe for, calls or commitments of any character
        whatsoever relating to, or securities or rights convertible into or
        exchangeable for, shares of any class of capital stock of Christiana, or
        contracts, understandings or arrangements to which Christiana is a
        party, or by which it is or may be bound, to issue additional shares of
        its capital stock or options, warrants, scrip or rights to subscribe
        for, or securities or rights convertible into or exchangeable for, any
        additional shares of its capital stock.
 
             (iv) Section 2.2(b)(iv) of the Christiana Disclosure Letter sets
        forth a list of all corporations, partnerships, limited liability
        companies and other entities of which Christiana owns directly or

          (c) Authorization and Validity of Agreement. Each of Christiana and C2
     has all requisite corporate power and authority to enter into this
     Agreement, the Logistic Purchase Agreement and the other agreements and
     instruments contemplated to be executed and delivered in connection with

     hereunder and thereunder. The execution and delivery by Christiana and C2
     of this Agreement and the Other Agreements to which it is a party and the
     consummation by it of the transactions contemplated hereby and thereby have
     been duly authorized by all necessary corporate action (subject only, with
     respect to the Merger and the Logistic Sale, to approval of this Agreement
     and the Logistic Sale by the Christiana stockholders as provided for in

     Christiana and C2 enforceable against it in accordance with its terms. The
     Other Agreements, when executed and delivered by Christiana and C2, as
     applicable, will constitute valid and binding obligations of Christiana and
     C2, enforceable against them in accordance with their respective terms.
    
 
   
          (d) No Approvals or Notices Required; No Conflict with Instruments to
     which Christiana is a Party. The execution and delivery of this Agreement
     and the Other Agreements do not, and the consummation of the transactions
     contemplated hereby and thereby and compliance with the provisions hereof
     and thereof will not, conflict with, or result in any violation of, or
     default (with or without notice or lapse of time, or both) under, or give
     rise to a right of termination, cancellation or acceleration of or "put"
     right with respect to any obligation or to loss of a material benefit
     under, or result in the creation of any Lien upon any of the properties or
     assets of Christiana, Logistic, C2 or any of their subsidiaries under, any
     provision of (i) the Christiana Articles or bylaws of Christiana, the
     Certificate of Organization or operating agreement of Logistic or the
     Articles of Incorporation or bylaws of C2, or any provision of the
     comparable organizational documents of its subsidiaries, (ii) except as set
     forth in Section 2.2(d) of the Christiana Disclosure Letter, any loan or
     credit agreement, note, bond, mortgage, indenture, lease, guaranty or other
     financial assurance agreement or other agreement, instrument, permit,
     concession, franchise or license applicable to Christiana or its properties
     or assets, (iii) except as set forth in Section 2.2(d) of the Christiana
     Disclosure Letter, any loan or credit agreement, note, bond, mortgage,

     to Logistic or any other Christiana Subsidiary, or their respective
     properties or assets and (iv) subject to governmental filing and other
     matters referred to in the following sentence, any judgment, order, decree,
     statute, law, ordinance, rule or regulation or arbitration award applicable
     to Christiana, Logistic or C2 or any of their subsidiaries or their
     respective properties or assets, other than, in the case of clauses (ii)
     and (iii), any such conflicts, violations, defaults, rights or Liens that
     individually or in the aggregate would not have a Christiana MAE. No
     consent, approval, order or authorization of, or registration, declaration
     or filing with, any court, administrative agency or commission or other
     governmental authority or agency, domestic or foreign, including local
     authorities (a "Governmental Entity"), is required by or with respect to
     Christiana, Logistic or C2 or any of their subsidiaries in connection with
     the execution and delivery of this Agreement by Christiana and C2 or the
     consummation by Christiana of the transactions contemplated hereby, except
     for (i) the filing of a pre-merger notification and report form by
     Christiana under the HSR Act, (ii) the filing with the Commission of (A) a
     proxy or information statement relating to Stockholder Approval (such proxy
     or information statement as amended or supplemented from time to time, the
     "Proxy Statement"), and (B) such reports under Section 13(a) of the
     Exchange Act as may be required in connection with this Agreement and the
     transactions contemplated hereby, (iii) the filing of the Certificate of
     Merger with the Wisconsin Secretary of State with respect to the Merger as
     provided in the WBCL and appropriate documents with the relevant
     authorities of other states in which Christiana is qualified to do business
     and (iv) such other consents, approvals, orders, authorizations,
     registrations, declarations, filings and notices as are set forth in
     Section 2.2(d) of the Christiana Disclosure Letter.
    
 
          (e) Commission Filings; Financial Statements. Christiana has filed all
     reports, registration statements and other filings, together with any
     amendments required to be made with respect thereto, that it has been
     required to file with the Commission. All reports, registration statements
     and other filings (including all notes, exhibits and schedules thereto and
     documents incorporated by reference therein) filed by Christiana with the
     Commission since December 31, 1995, through the date of this Agreement,
                                      A-11
<PAGE>   154
 
     together with any amendments thereto, are sometimes collectively referred
     to as the "Christiana Commission Filings." Christiana has heretofore
     delivered to Weatherford copies of the Christiana Commission Filings. As of
     the respective dates of their filing with the Commission, the Christiana
     Commission Filings complied in all material respects with the Securities
     Act, the Exchange Act and the rules and regulations of the Commission
     thereunder, and did not contain any untrue statement of a material fact or
     omit to state a material fact required to be stated therein or necessary to
     make the statements made therein, in light of the circumstances under which
     they were made, not misleading. To the best knowledge of Christiana, all
     material contracts of Christiana and its subsidiaries have been included in
     the Christiana Commission Filings since the initial registration of its
     stock under the Exchange Act, except for those contracts not required to be
     filed pursuant to the rules and regulations of the Commission.
 
          Each of the consolidated financial statements (including any related
     notes or schedules) included in the Christiana Commission Filings was
     prepared in accordance with generally accepted accounting principles
     applied on a consistent basis (except as may be noted therein or in the
     notes or schedules thereto) and complied with the rules and regulations of
     the Commission. Such consolidated financial statements fairly present the
     consolidated financial position of Christiana as of the dates thereof and
     the results of operations, cash flows and changes in stockholders' equity
     for the periods then ended (subject, in the case of the unaudited interim
     financial statements, to normal year-end audit adjustments on a basis
     comparable with past periods). As of the date hereof, Christiana has no
     liabilities, absolute or contingent, that may reasonably be expected to
     have a Christiana MAE, that are not reflected in the Christiana Commission
     Filings, except (i) those incurred in the ordinary course of business
     consistent with past operations and not relating to the borrowing of money
     and (ii) those set forth in Section 2.2(e) of the Christiana Disclosure
     Letter.
 
   
          (f) Conduct of Business in the Ordinary Course; Absence of Certain
     Changes and Events. Since December 31, 1995, except as contemplated by this
     Agreement, the Logistic Purchase Agreement or as disclosed in the
     Christiana Commission Filings or set forth in Section 2.2(f) of the
     Christiana Disclosure Letter, Christiana and its subsidiaries have
     conducted their respective businesses only in the ordinary and usual course
     in accordance with past practice, and there has not been: (i) a Christiana
     MAE or any other material adverse change in the financial condition,
     results of operations, assets or business of Christiana, taken as a whole;
     (ii) to the knowledge of Christiana, any other condition, event or
     development that reasonably may be expected to result in any such material
     adverse change or a Christiana MAE; (iii) any change by Christiana or
     Logistic in its accounting methods, principles or practices; (iv) any
     revaluation by Christiana or Logistic of any of its assets, including,
     without limitation, writing down the value of inventory or writing off
     notes or accounts receivable other than in the ordinary course of business
     and consistent with past practice; (v) any entry by Christiana or Logistic
     into any commitment or transaction that would be material to Christiana or
     Logistic; (vi) any declaration, setting aside or payment of any dividends
     or distributions in respect of the Christiana Common Stock or any
     redemption, purchase or other acquisition of any of its securities; (vii)
     any damage, destruction or loss (whether or not covered by insurance)
     adversely affecting the properties or business of Christiana or Logistic;
     (viii) any increase in indebtedness of borrowed money other than borrowing
     under existing credit facilities as disclosed in Section 2.2(f) of the
     Christiana Disclosure Letter; (ix) any granting of a security interest or
     Lien on any property or assets of Christiana or Logistic, other than (A)
     Liens for taxes not due and payable and (B) inchoate mechanics',
     warehousemen's and other statutory Liens incurred in the ordinary course of
     business (collectively, "Permitted Liens"); or (x) any increase in or
     establishment of any bonus, insurance, severance, deferred compensation,
     pension, retirement, profit sharing, stock option (including, without
     limitation, the granting of stock options, stock appreciation rights,
     performance awards or restricted stock awards), stock purchase or other
     employee benefit plan or any other increase in the compensation payable or
     to become payable to any directors, officers or key employees of Christiana
     or Logistic or which Christiana or Logistic would be responsible.
    
 
          (g) Litigation. Except as disclosed in the Christiana Commission
     Filings or as set forth in Section 2.2(g) of the Christiana Disclosure
     Letter, there are no claims, actions, suits, investigations,
 
                                      A-12

     inquiries or proceedings, ("Demands"), pending or, to the knowledge of
     Christiana, threatened against or affecting (i) Christiana or Logistic or
     any of their respective properties at law or in equity, or any of their
     employee benefit plans or fiduciaries of such plans, or (ii) C2 or any
     Christiana or C2 subsidiaries or any of their respective properties at law
     or in equity, or any of their respective employee benefit plans or
     fiduciaries of such plans, before or by any federal, state, municipal or
     other governmental agency or authority, or before any arbitration board or
     panel (each a "Governmental Entity"), wherever located (i) that exist today
     or (ii) that would otherwise, if adversely determined, have a Christiana
     MAE. None of Christiana, Logistic or C2 is subject to any judicial,
     governmental or administrative order, writ, judgment, injunction or decree.
    
 
          (h) Employee Benefit Plans.
 
             (i) Section 2.2(h) of the Christiana Disclosure Letter provides a
        description of each of the following which is sponsored, maintained or

        Section 414(b),(c),(m) or (o) of the Code or Section 4001 of ERISA (a
        "Christiana ERISA Affiliate") for the benefit of its employees, or has
        been so sponsored, maintained or contributed to within three years prior
        to the Closing Date.
 
                (A) each "employee benefit plan," as such term is defined in
           Section 3(3) of the Employee Retirement Income Security Act of 1974,
           as amended ("ERISA"), ("Plan"); and
 
   
                (B) each stock option plan, collective bargaining agreement,
           bonus plan or arrangement, incentive award plan or arrangement,
           vacation policy, severance pay plan, policy or agreement, deferred
           compensation agreement or arrangement, executive compensation or
           supplemental income arrangement, consulting agreement, employment
           agreement and each other employee benefit plan, agreement,
           arrangement, program, practice or understanding that is not described
           in Section 2.2(h)(i)(A) to which Christiana or Logistic is a party or
           has any obligation ("Benefit Program or Agreement").
    
 
                True and complete copies of each of the Plans, Benefit Programs
           or Agreements, related trusts, if applicable, and all amendments
           thereto, together with (i) the Forms 5500, 990 and 1041, as
           applicable, for the three most recent fiscal years, (ii) all current
           summary plan descriptions for each such Plan, (iii) the most recent
           Internal Revenue Service determination letters for each such Plan, as
           applicable, and all correspondence with the Internal Revenue Service
           and the Department of Labor relating to such Plans, Benefit Programs
           and Agreements have been furnished to Weatherford.
 
             (ii) Except as otherwise set forth in Section 2.2(h) of the
        Christiana Disclosure Letter,
 
                (A) None of Christiana or any Christiana ERISA Affiliate
           contributes to or has an obligation to contribute to, or has at any
           time contributed to or had an obligation to contribute to, a plan
           subject to Title IV of ERISA, including, without limitation, a multi
           employer plan within the meaning of Section 3(37) of ERISA, nor have
           such companies engaged in any transaction described in Sections 406
           and 407 of ERISA (unless exempt under Section 408) or Section 4975 of
           the Code (unless exempt);
 
                (B) Each Plan and each Benefit Program or Agreement has been
           administered, maintained and operated in all material respects in
           accordance with the terms thereof and in compliance with its
           governing documents and applicable law (including, where applicable,
           ERISA and the Code and timely filing of Form 5500s for each year);
 
                (C) There is no matter pending with respect to any of the Plans
           before any governmental agency, and there are no actions, suits or
           claims pending (other than routine claims for benefits) or, to the
           knowledge of Christiana or C2, threatened against, or with respect
           to, any of the Plans or Benefit Programs or Agreements or its assets;
 
                                      A-13
<PAGE>   156
 
                (D) No act, omission or transaction has occurred which would
           result in imposition on Christiana or any Christiana ERISA Affiliate
           of breach of fiduciary duty liability damages under Section 409 of
           ERISA, a civil penalty assessed pursuant to subsections (c), (i) or
           (l) of Section 502 of ERISA or a tax imposed pursuant to Chapter 43
           of Subtitle D of the Code; and
 
                (E) Except as provided in Section 5.7, the execution and
           delivery of this Agreement and the consummation of the transactions
           contemplated hereby will not require Christiana or any Christiana
           ERISA Affiliate to make a larger contribution to, or pay greater
           benefits under, any Plan, Benefit Program or Agreement than it
           otherwise would or create or give rise to any additional vested
           rights or service credits under any Plan or Benefit Program or
           Agreement or cause the companies to make accelerated payments.
 
             (iii) Except as set forth in Section 2.2(h) of the Christiana
        Disclosure Letter, termination of employment of any employee of
        Christiana immediately after consummation of the transactions
        contemplated by this Agreement would not result in payments under the
        Plans, Benefit Programs or Agreements which, in the aggregate, would
        result in imposition of the sanctions imposed under Sections 280G and
        4999 of the Code.
 
             (iv) Each Plan may be unilaterally amended or terminated in its
        entirety without liability except as to benefits accrued thereunder
        prior to such amendment or termination.
 
   
             (v) Except as set forth in Section 2.2(h) of the Christiana
        Disclosure Letter, none of the employees of Christiana or Logistic are
        subject to union or collective bargaining agreements.
    
 
             (vi) None of Christiana or any of the Christiana ERISA Affiliates
        has agreed or is obligated to provide retiree medical coverage and each
        of such companies has fully complied with all obligations under COBRA
        applicable to it.
 
          (i) Taxes.
 
             (i) Except as set forth in Section 2.2(i) of the Christiana
        Disclosure Letter, all Tax Returns of or relating to any Tax that are
        required to be filed on or before the Closing Date by or with respect to
        Christiana or any Christiana Subsidiary, or any other corporation that
        is or was a member of an affiliated group (within the meaning of Section
        1504(a) of the Code) of corporations of which Christiana was a member
        for any period ending on or prior to the Closing Date, have been or will
        be duly and timely filed, and all Taxes, including interest and
        penalties, due and payable pursuant to such Tax Returns have been or
        will be duly and timely paid or adequately provided for in reserves
        established by Christiana or any such Christiana Subsidiary, except
        where the failure to file, pay or provide for would not have a material
        adverse effect on the financial condition, results of operations, or
        business of Christiana or otherwise result in a Christiana MAE. All
        income Tax Returns of or with respect to Christiana or any Christiana
        Subsidiary have been audited by the applicable Governmental Authority,
        or the applicable statute of limitations has expired, for all periods up
        to and including the tax year ended June 30, 1993. There is no material
        claim against Christiana or any Christiana Subsidiary with respect to
        any Taxes, and no material assessment, deficiency or adjustment has been
        asserted or proposed with respect to any Tax Return of or with respect
        to Christiana or any Christiana Subsidiary that has not been adequately
        provided for in reserves established by Christiana or such Christiana
        Subsidiary. The total amounts set up as liabilities for current and
        deferred Taxes in the consolidated financial statements included in the
        Christiana Commission Filings have been prepared in accordance with
        generally accepted accounting principles and are sufficient to cover the
        payment of all material Taxes, including any penalties or interest
        thereon and whether or not assessed or disputed, that are, or are
        hereafter found to be, or to have been, due with respect to the
        operations of Christiana or any Christiana Subsidiary through the
        periods covered thereby. Christiana has (and as of the Closing Date will
        have) made estimated tax payments for taxable years for which the United
        States consolidated federal income Tax return is not yet due required
        with respect to Taxes. Except as set forth in Section 2.2(i) of the
        Christiana Disclosure Letter, no waiver or extension of any statute of
        limitations as to any federal, state, local or
 
                                      A-14
<PAGE>   157
 
        foreign Tax matter has been given by or requested from Christiana or any
        Christiana Subsidiary. Except for statutory Liens for current Taxes not
        yet due, no Liens for Taxes exist upon the assets of Christiana. Except
        as set forth in paragraph 2.2(i) of the Christiana Disclosure Letter,
        none of Christiana or any Christiana Subsidiary has filed consolidated
        income Tax Returns with any corporation, other than consolidated
        federal, state or foreign income Tax returns by Christiana for any
        taxable period which is not now closed by the applicable statute of
        limitations. Except as set forth in Section 2.2(i) of the Christiana
        Disclosure Letter, none of Christiana or any Christiana Subsidiary has
        any deferred intercompany gain as defined in Treasury Regulations
        Section 1.1502-13.
 
             (ii) As of the Closing Date, to Christiana's knowledge, there is no
        plan or intention by the stockholders of Christiana to sell, exchange or
        otherwise dispose of a number of shares of Weatherford received in the
        Merger that would reduce the Christiana stockholders' ownership of
        Weatherford shares to a number of shares having a value, as of the date
        of the Merger, of less than 50% of the value of all of the formerly
        outstanding Christiana Shares as of the same date. The shares of
        Weatherford Common Stock held by the Christiana stockholders and
        otherwise sold, redeemed or disposed of prior or subsequent to the
        Merger will be considered in making this representation.
 
             (iii) Christiana is not under the jurisdiction of a court in a
        Title 11 or similar case with the meaning of sec.368(a)(3)(A) of the
        Code.
 
             (iv) There is no intercorporate indebtedness existing between
        Christiana and Weatherford that was issued, acquired or will be settled
        at a discount.
 
   
             (v) As of the Closing Date, Christiana shall have fully accrued for
        all Taxes that may be required to be paid as a result of the Logistic
        Sale and the other transactions contemplated hereby. The value of the
        interest in Logistic Common Stock to be sold pursuant to the Logistic
        Sale has been determined pursuant to an outside appraisal and reflects
        an amount equal to or greater than the fair value and fair market value
        of such shares.
    
 
   
          (j) Environmental Matters. Except as set forth in Section 2.2(j) of
     the Christiana Disclosure Letter, (i) the properties, operations and
     activities of Christiana and each of its Subsidiaries complies in all
     material respects with all applicable Environmental Laws; (ii) none of
     Christiana or any of its Christiana Subsidiaries is subject to any
     existing, pending or, to the knowledge of Christiana, threatened action,
     suit, investigation, inquiry or proceeding by or before any governmental
     authority under any Environmental Law; (iii) except where the failure would
     have a Christiana MAE, all notices, permits, licenses, or similar
     authorizations, if any, required to be obtained or filed by Christiana
     under any Environmental Law in connection with any aspect of the business
     of Christiana, Logistic or any Christiana Subsidiary, including without
     limitation those relating to the treatment, storage, disposal or release of
     a hazardous substance or solid waste, have been duly obtained or filed and
     will remain valid and in effect after the Merger and the Logistic Sale, and
     each of Christiana, Logistic and each other Christiana Subsidiary is in
     compliance with the terms and conditions of all such notices, permits,
     licenses and similar authorizations; (iv) Christiana and each of its
     Subsidiaries has satisfied and are currently in compliance with all
     financial responsibility requirements applicable to their operations and
     imposed by any governmental authority under any other Environmental Law,
     and none of such parties has received any notice of noncompliance with any
     such requirements; (v) to Christiana's knowledge, there are no physical or
     environmental conditions existing on any property currently owned or
     previously owned by Christiana or any entity in which it has or had
     ownership interest that could reasonably be expected to give rise to any
     on-site or off-site remedial obligations under any Environmental Laws; and
     (vi) to Christiana's knowledge, since the effective date of the relevant
     requirements of applicable Environmental Laws, all hazardous substances or
     solid wastes generated by Christiana or used in connection with their
     properties or operations have been transported only by carriers authorized
     under Environmental Laws to transport such substances and wastes, and
     disposed of only at treatment, storage, and disposal facilities authorized
     under environmental laws to treat, store or dispose of such substances and
     wastes, and, to the knowledge of Christiana, such carriers and facilities
     have been and are operating in compliance with such
    
 
                                      A-15
<PAGE>   158
 
     authorizations and are not the subject of any existing, pending, or overtly
     threatened action, investigation, or inquiry by any governmental authority
     in connection with any Environmental Laws.
 
          For purposes of this Agreement, the term "Environmental Laws" shall
     mean any and all laws, statutes, ordinances, rules, regulations, orders or
     determinations of any Governmental Authority pertaining to health or the
     environment currently in effect in any and all jurisdictions in which the
     party in question and its subsidiaries own property or conduct business,
     including without limitation, the Clean Air Act, as amended, the
     Comprehensive Environmental, Response, Compensation, and Liability Act of

        relating to the borrowing of funds, including any and all guarantees or
        similar arrangements relating thereto.
    
 
   
          (p) Compliance with Laws. Christiana, Logistic, C2 and each of their
     respective subsidiaries hold all required, necessary or applicable permits,
     licenses, variances, exemptions, orders, franchises and approvals of all
     Governmental Entities, except where the failure to so hold could not
     reasonably be expected to have a Christiana MAE (the "Christiana Permits").
     All applications with respect to such permits, licenses, variances,
     exemptions, orders, franchises and approvals were complete and correct in
     all material respects when made and neither Christiana nor C2 know of any
     reason why any of such permits, licenses, variances, exemptions, orders,
     franchises and approvals would be subject to cancellation. Christiana,
     Logistic, C2 and each of their respective subsidiaries are in compliance
     with the terms of the Christiana Permits except where the failure to so
     comply could not reasonably be expected to have a Christiana MAE. None of
     Christiana, Logistic, C2 or any of their respective subsidiaries has
     violated or failed to comply with any statute, law, ordinance, regulation,
     rule, permit or order of any Federal, state or local government, domestic
     or foreign, or any Governmental Entity, any arbitration award or any
     judgment, decree or order of any court or other Governmental Entity,
     applicable to Christiana, Logistic, C2 or any of their respective
     subsidiaries or their respective business, assets or operations, except for

        outstanding bonds, letters of credit posted or guaranteed by Christiana

             (ii) True and correct copies of all the instruments described in
        Section 2.2(q) of the Christiana Disclosure Letter have been furnished
        or made available to Weatherford. Except as noted in the Christiana
        Disclosure Letter, all such agreements, arrangements or commitments are
        valid and subsisting and each of Christiana, Logistic and their
        respective subsidiaries to the extent each is a party, has duly
        performed its obligations thereunder in all material respects to the
        extent such obligations have accrued, and no breach or default
        thereunder by Christiana, Logistic or their respective subsidiaries or,
        to the knowledge of Christiana, any other party thereto has occurred
        that could impair the ability of Christiana, Logistic or their
        respective subsidiaries to enforce any material rights thereunder. There
        are no material liabilities of any of the parties to any of the
        contracts between Christiana, Logistic or C2 or any of their respective
        subsidiaries and third parties arising from any breach of or default in
        any provision thereof or which would permit the acceleration of any
        obligation of any party thereto or the creation of a Lien upon any asset
        of Christiana, Logistic or any of their respective subsidiaries.
    
 
          (r) Title to Property.
 
   
             (i) At the Effective Time, Christiana will have good and marketable
        title to, or valid leasehold interests in, all its properties and
        assets. Christiana has good and valid title to 3,897,462 shares of
        Weatherford Common Stock, free and clear of all Liens. Christiana has

        material respects with the terms of all leases to which it is a party
        and under which it is in occupancy, and all such leases are in full
        force and effect. Each of Christiana and Logistic enjoys peaceful and
        undisturbed possession under all such leases.
    
 
   
          (s) Insurance Policies. Section 2.2(s) of the Christiana Disclosure
     Letter contains a correct and complete description of all insurance
     policies of Christiana covering Christiana, Logistic and their respective
     subsidiaries, any employees or other agents of Christiana, Logistic and
     their respective subsidiaries or any assets of Christiana and its
     subsidiaries. Each such policy is in full force and effect, is with
     responsible insurance carriers and is substantially equivalent in coverage
     and amount to policies covering companies of the size of Christiana and in
     the business in which Christiana and its subsidiaries is engaged, in light
     of the risk to which such companies and their employees, businesses,
     properties and other assets may be exposed. All retroactive premium
     adjustments under any worker's compensation policy of Christiana or any of
     its Subsidiaries have been recorded in Christiana's financial statements in
     accordance with generally accepted accounting principles and are reflected
     in the financial statements contained in the Commission Filings.
    
 
   
          (t) Loans. Section 2.2(t) of the Christiana Disclosure Letter sets
     forth all existing loans, advances or other extensions of credit (excluding
     accounts receivable arising in the ordinary course of business) by
     Christiana or its subsidiaries to any party other than intercompany loans,
     advances, guaranties or extensions of credit. All items listed in Section
     2.2(t) of the Christiana Disclosure Letter will be repaid in full or
     assumed by C2 prior to the Effective Time of the Merger. All intercompany
     obligations and loans between Christiana and its subsidiaries, including
     C2, will be extinguished prior to the Logistic Sale without any ongoing
     liability to Christiana or C2 with respect thereto, except as set forth
     herein or in the Logistic Purchase Agreement.
    
 
   
          (u) No Fraudulent Transfer. Christiana has not within the last twelve
     months made any transfer or incurred any obligation with actual intent to
     hinder, delay or defraud any entity to which it was or may become indebted
     and it has not transferred any material property without receiving
     reasonably equivalent value for any such transfer obligation. Both
     immediately prior to and immediately after the Logistic Sale and the
     Merger, (i) the fair value of (x) Christiana's assets at the time of the
     Merger and (y) Logistic's and C2's assets after the Logistic Sale and (z)
     the assets of CST Financial, Inc. ("CST") Martinique Holdings, Inc. ("MHI")
     and Christiana Community Builders, Inc. ("CCB") immediately prior to their
     liquidation in each case at a fair valuation exceeds their respective debts
     and liabilities, subordinated,
    
                                      A-18
<PAGE>   161
 
   
     contingent or otherwise, (ii) the present fair saleable value of
     Christiana's, Logistic's, C2's, CST's, MHI's and CCB's property is greater
     than the amount that will be required to pay its probable liability on
     their respective debts and other liabilities, subordinated, contingent or
     otherwise, as such debts and liabilities become absolute and mature, (iii)
     Christiana prior to the Logistic Sale and Logistic, C2 after the Logistic
     Sale and CST, MHI and CCB prior to their liquidation each reasonably expect
     to be able to pay its debts and liabilities, subordinated, contingent or
     otherwise, as such debts and liabilities become absolute and matured, and
     (iv) Christiana before the Logistic Sale and Logistic and C2 after the
     Logistic Sale will not have unreasonably small capital with which to
     conduct the business in which it is engaged as such business is now
     conducted and is proposed to be conducted. For all purposes of clauses of
     (i) through (iv), the amount of contingent liabilities at any time shall be
     computed as the amount that, in light of all the facts and circumstances
     existing at such time, represents the amount that can reasonably be
     expected to become an actual or matured liability.
    
 
          (v) Information Supplied. None of the information supplied or to be
     supplied by Christiana or C2 for inclusion or incorporation by reference in
     (i) the Registration Statement (as defined in Section 5.1) will, at the
     time the Registration Statement is filed with the Commission, and at any
     time it is amended or supplemented or at the time it becomes effective
     under the Securities Act, contain any untrue statement of a material fact
     or omit to state any material fact required to be stated therein or
     necessary to make the statements therein not misleading, and (ii) the Proxy
     Statement will, at the date the Proxy Statement is first mailed to
     Christiana's stockholders and at the time of the Christiana Stockholders
     Meeting, contain any untrue statement of a material fact or omit to state
     any material fact required to be stated therein or necessary in order to
     make the statements therein, in light of the circumstances under which they
     are made, not misleading. The Proxy Statement will comply as to form in all
     material respects with the requirements of the Exchange Act and the rules
     and regulations thereunder. For purposes of this Agreement, the parties
     agree that the statements made and information in the Registration
     Statement and the Proxy Statement relating to the Federal income tax
     consequences of the transactions contemplated hereby shall be deemed to be
     supplied by Christiana and C2 and not by Weatherford or Sub.

     shall cause all of its obligations (i) relating to Logistic or any other
     historical business of Christiana or its Subsidiaries and (ii) under any
     and all agreements relating to the borrowing of funds, including all
     guarantees and other similar arrangements relating thereto, to be fully
     released or otherwise satisfied in a manner acceptable to Weatherford.
    
 
   
     3.2  CASH REQUIREMENTS. Christiana covenants that as of the Effective Time
it shall have cash equal to the sum of (i) $13 million (including $10,666,677 to
be received under the Logistic Purchase Agreement) and (ii) all accrued and
unpaid liabilities and obligations of Christiana. For purposes of this Section
3.2, the unpaid liabilities and obligations of Christiana shall mean the full
undiscounted amount of liabilities for which Christiana shall be responsible,
including any liabilities that will accrue as a result of the Merger, the
Logistic Sale or the transactions contemplated herein, whether or not such
liabilities would be required to be reflected as a liability by generally
accepted accounting principles; provided, however, that such liabilities shall
not include any liabilities for any gain on any Weatherford Common Stock held by
Christiana realized as a result of a sale of such stock by Christiana or a
liquidation or merger of Christiana (other than the Merger) within two years
after the Effective Time, nor any tax liability for income of Weatherford
attributable to Christiana under the equity method of accounting either before
or after the Effective Time (the "Weatherford Related Taxes"). Further, for
purposes of calculating such liabilities, any Taxes (other than the Weatherford
Related Taxes) payable in respect of the Logistic Sale or other transactions
contemplated herein or under the Logistic Purchase Agreement shall be fully
accrued as a liability and any Tax credits, deductions, other Tax benefits of
Christiana shall not be considered or used to offset any such liability. The
provisions of this Section 3.2 shall not affect Logistic's and C2's obligations
under the Logistic Purchase Agreement to assume and indemnify Weatherford as set
forth therein.

     3.3  AFFILIATES' AGREEMENTS. Prior to the Closing Date, Christiana shall

"affiliates" of Christiana for purposes of Rule 145 under the Securities Act
("Affiliates"). Christiana shall deliver or cause to be delivered to Weatherford
an undertaking by each Affiliate in form satisfactory to Weatherford that no
Weatherford Common Stock received or to be received by such Affiliate pursuant

After the Christiana Stockholders Meeting, as defined in Section 5.3, Christiana
shall purchase, in one transaction or a series of transactions, up to an
additional $5 million of Weatherford Common Stock (the "$5 Million Purchase").
Notwithstanding the foregoing, Christiana shall not be required to make any
purchase unless such purchase, when considering the then current price of
Weatherford Common Stock, prior purchases and amounts, if any, remaining under
the $10 Million Purchase and the $5 Million Purchase, will allow the Merger when
completed to qualify as a reorganization within the meaning of Section
368(a)(1)(A) by reason of Section 368(a)(2)(E) of the Code. Christiana may, but
is not required to, waive the foregoing and purchase any other Weatherford
Common Stock. All such purchases shall be made in accordance with applicable
securities laws, including Regulation M and Rule 10b-18 promulgated under the
Exchange Act.

     7.8  GOVERNING LAW. All questions arising out of this Agreement and the
rights and obligations created herein, or its validity, existence,
interpretation, performance or breach shall be governed by the laws of the State
of Delaware, without regard to conflict of laws principles.
 
     7.9  ARBITRATION. Any disputes, claims or controversies connected with,
arising out of, or related to, this Agreement and the rights and obligations
created herein, or the breach, validity, existence or termination hereof, shall
be settled by Arbitration to be conducted in accordance with the Commercial
Rules of Arbitration of the American Arbitration Association, except as such
Commercial Rules may be changed by this Section 7.9. The disputes, claims or
controversies shall be decided by three independent arbitrators (that is,
arbitrators having no substantial economic or other material relationship with
the parties), one to be appointed by Christiana, if prior to the Merger, or C2,
if after the Merger, and one to be appointed by Weatherford within fourteen days
following the submission of the claim to the parties hereto and the third to be
appointed by the two so appointed within five days thereafter. Should either
party refuse or neglect to join in the timely appointment of the arbitrators,
the other party shall be entitled to select both arbitrators. Should the two
arbitrators fail timely to appoint a third arbitrator, either party may apply to
the Chief Judge of the United States District Court for the Southern District of
Texas to make such appointment. The arbitrators shall have ninety days after the
selection of the third arbitrator within which to allow discovery, hear evidence
and issue their decision or award and shall in good faith attempt to comply with
such time limits; provided, however, if two of the three arbitrators believe
additional time is necessary to reach a decision, they may notify the parties
and extend the time to reach a decision in thirty day increments, but in no
event to exceed an additional ninety days. Discovery of evidence shall be
conducted expeditiously by the parties, bearing in mind the parties desire to
limit discovery and to expedite the decision or award of the arbitrators at the
most reasonable cost and expense of the parties. Judgment upon an award rendered
pursuant to such Arbitration may be entered in any court having jurisdiction, or
application may be made to such court for a judicial acceptance of the award,
and an order of enforcement, as the case may be. The place of Arbitration shall
be Houston, Texas. The decision of the arbitrators, or a majority thereof, made
in writing, shall be final and binding upon the parties hereto as to the
questions submitted, and each party shall abide by such decision.
Notwithstanding the provisions of this Section 7.9, neither party shall be
prohibited from seeking injunctive relief pending the completion of any
arbitration. The costs and expenses of the arbitration proceeding, including the
fees of the arbitrators and all costs and expenses, including legal fees and
witness fees, incurred by the prevailing party, shall be borne by the losing
party.
 
     Solely for purposes of injunctive relief, orders in aid of arbitration and
entry of the arbitrators' award:
 
   
          (a) each of the parties hereto irrevocably consents to the
     non-exclusive jurisdiction of, and venue in, any state court located in

     orders in aid of arbitration, or entry of an arbitral award arising out of
     or relating to this Agreement or any of the other agreements contemplated
     hereby and any other court in which a matter that may result in a claim for
     indemnification hereunder by a Weatherford Indemnified Party (as defined in
     the Logistic Purchase Agreement) may be brought with respect to any claim
     for indemnification by a Weatherford Indemnified Party;
    
 
   
          (b) each of the parties hereto waives, to the fullest extent permitted
     by law, any objection that it may now or hereafter have to the laying of
     venue of any suit, action or proceeding seeking injunctive relief, orders
     in aid of arbitration or entry of an arbitral award arising out of or
     relating to this Agreement or any of the other agreements contemplated
     hereby brought in any state court located in Harris County, Texas or any
     federal court sitting in the Southern District of Texas or any other court
     in which a matter that may result in a claim hereunder or for
     indemnification under the Logistic Purchase Agreement by a Weatherford
     Indemnified Party may be brought with respect to any claim for
     indemnification by a

<PAGE>   173
 
     Weatherford Indemnified Party, and further irrevocably waive any claim that
     any such suit, action or proceeding brought in any such court has been
     brought in an inconvenient forum;
 
          (c) each of the parties hereto irrevocably designates, appoints and
     empowers CT Corporation System, Inc. and any successor thereto as its
     designee, appointee and agent to receive, accept and acknowledge for and on
     its behalf, and in respect of its property, service of any and all legal

     relief, orders in aid of arbitration and entry of an arbitral award.

     7.13  CONFIDENTIALITY Agreement. The Confidentiality Agreements entered
into between Weatherford and Christiana on December 10, 1997 (the
"Confidentiality Agreements") are hereby incorporated by reference herein and
made a part hereof.

Other Agreements and the Confidentiality Agreements constitute the entire
agreement and supersede all other prior agreements and understandings, both oral
and written, among the parties or any of them, with respect to the subject
matter hereof and neither this nor any document delivered in connection with
this Agreement confers upon any Person not a party hereto any rights or remedies
hereunder.

     Agreement shall be construed to be an assumption of any obligation or
     responsibility by Weatherford of any Assumed Liabilities and its
     obligations hereunder shall be personal to TLC and C2 to the extent and
     only to the extent Weatherford has agreed to fund the payment of indemnity
     claims by it with the Christiana Retained Cash as expressly provided
     herein. No third party shall be deemed to have any rights against
     Weatherford as result of this Agreement.
 
     (c)  Absolute Indemnity. NONE OF THE WEATHERFORD INDEMNIFIED PARTIES WILL
BE OBLIGATED TO INSTITUTE ANY LEGAL PROCEEDINGS IN CONNECTION WITH THE
COLLECTION OR PURSUIT OF ANY INSURANCE IN ORDER TO EXERCISE AN INDEMNIFICATION
REMEDY UNDER THIS SECTION VI. UNLESS OTHERWISE SPECIFICALLY EXPRESSED, THIS
INDEMNITY OBLIGATION SHALL APPLY WITHOUT REGARD TO WHETHER THE LIABILITY OR
ENVIRONMENTAL LIABILITY WAS CAUSED BY THE ORDINARY OR GROSS NEGLIGENCE OF ANY OF
THE WEATHERFORD INDEMNIFIED PARTIES (WHETHER SUCH NEGLIGENCE BE SOLE, JOINT OR
CONCURRENT OR ACTIVE OR PASSIVE), OR WHETHER THE LIABILITY OR ENVIRONMENTAL
LIABILITY IS BASED ON STRICT LIABILITY, ABSOLUTE LIABILITY OR ARISES AS AN
OBLIGATION OF CONTRIBUTION OR INDEMNITY. EACH OF C2 AND TLC ACKNOWLEDGES THAT IT
IS AWARE OF VARIOUS THEORIES KNOWN AS THE "EXPRESS NEGLIGENCE" DOCTRINE AND
OTHER SIMILAR DOCTRINES AND THEORIES THAT MAY LIMIT INDEMNIFICATION AND AGREES
                                       B-8

AND STIPULATES THAT THE PROVISIONS OF THIS AGREEMENT REFLECT THE EXPRESS INTENT
OF THE PARTIES THAT THE INDEMNIFICATION TO BE PROVIDED BY TLC AND C2 APPLY
NOTWITHSTANDING THE FACT THAT THE LIABILITY OR ENVIRONMENTAL LIABILITY (I) MAY
NOT CURRENTLY BE KNOWN BY IT OR MANIFEST ITSELF IN ANY REGARD, (II) MAY ARISE
UNDER A STATUTE OR THEORY THAT MAY NOT CURRENTLY EXIST OR BE KNOWN TO TLC, (III)
MAY ARISE AS A RESULT OF A NEGLIGENT ACT OR OMISSION BY ANY OF THE WEATHERFORD
INDEMNIFIED PARTIES (WHETHER SUCH CONDUCT BE SOLE, JOINT OR CONCURRENT OR ACTIVE
OR PASSIVE) OR (IV) MAY CONSTITUTE A VIOLATION OF ANY APPLICABLE CIVIL OR
CRIMINAL LAW OR REGULATION.
 
     6.2  Notice of Circumstance. After receipt by a Weatherford Indemnified
Party of notice, or a Weatherford Indemnified Party's actual discovery, of any
action, proceeding, claim, demand or potential claim which could give rise to a
right to indemnification pursuant to any provision of this Agreement (any of
which is individually referred to a as a "Circumstance"), the Weatherford
Indemnified Party shall give TLC and C2 (collectively the "TLC Parties") written
notice describing the Circumstances in reasonable detail; provided, however,
that no delay by a Weatherford Indemnified Party in notifying the TLC Parties
shall relieve the TLC Parties from any Liability or Environmental Liability
hereunder unless (and then solely to the extent) the TLC Parties' position is
actually adversely prejudiced. In the event the TLC Parties notifies the
Weatherford Indemnified Party within 15 days after such notice that the TLC
Parties is assuming the defense thereof, (i) the TLC Parties will defend the
Weatherford Indemnified Parties against the Circumstances with counsel of its
choice, provided such counsel is reasonably satisfactory to Weatherford, (ii)
the Weatherford Indemnified Parties may retain separate co-counsel at its or
their sole cost or expense (except that the TLC Parties will be responsible for
the fees and expenses for the separate co-counsel to the extent Weatherford
concludes reasonably that the counsel the TLC Parties has selected has a
conflict of interest), (iii) the Weatherford Indemnified Parties will not
consent to the entry of any judgment or enter into any settlement with respect
to the Circumstances without the written consent of the TLC Parties, and (iv)
the TLC Parties will not consent to the entry of any judgment with respect to
the Circumstances, or enter into any settlement which (x) requires any payments
by or continuing obligations of a Weatherford Indemnified Party, (y) requires a
Weatherford Indemnified Party to admit any facts or liability that could
reasonably be expected to adversely affect a Weatherford Indemnified Party in
any other matter or (z) does not include a provision whereby the plaintiff or
claimant in the matter released the Weatherford Indemnified Parties from all
Liability with respect thereto, without the written consent of Weatherford. In
the event the TLC Parties does not notify Weatherford within 15 days after
Weatherford has given notice of the Circumstance that the TLC Parties is
assuming the defense thereof, the Weatherford Indemnified Parties may defend
against, or enter into any settlement with respect to, the Circumstance in any
manner the Weatherford Indemnified Parties reasonably may deem appropriate, at
the TLC Parties' sole cost. The foregoing provisions shall be subject to the
provisions of Section 6.1(b).
 
     6.3  Insurance. The TLC Parties shall not be obligated to indemnify the
Weatherford Indemnified Parties for amounts which shall have been covered and
paid by insurance of the Weatherford Indemnified Parties, provided, however,
insurance shall not include deductibles or self-insured retentions.
 
     6.4  Scope of Indemnification. INDEMNIFICATION UNDER THIS SECTION VI SHALL
BE IN ADDITION TO ANY REMEDIES CHRISTIANA, WEATHERFORD OR ANY WEATHERFORD
INDEMNIFIED PARTY MAY HAVE AT LAW OR EQUITY. THERE SHALL BE NO TIME LIMIT AS TO
C2'S OR TLC'S INDEMNIFICATION OBLIGATIONS HEREUNDER.
 
     6.5  Indemnity for Certain Environmental Liabilities. It is the intention
of the parties that the indemnity provided herein with respect to Environmental
Liabilities under CERCLA and corresponding provisions of state law is an
agreement expressly not barred by 42 U.S.C. Section 9607(e)(i) and corresponding
provisions of state law.
 
     6.6  C2 and TLC Covenants. To assure the performance of the obligations of
C2 and TLC under this Agreement, C2 and TLC each hereby covenants and agrees
that it will not, and will cause its subsidiaries to not, merge, convert into
another entity, engage in a share or interest exchange for a majority of its
units or
 
                                       B-9
<PAGE>   185
 
shares, liquidate or transfer, assign or otherwise convey or allocate, directly
or indirectly, in one or more transactions, whether or not related, a majority
of C2's or TLC's assets (determined in good faith by a board or similar managing
body's resolution prior to the transaction on a fair value and consolidated
basis) to any Person unless the acquiring Person expressly assumes the
obligations of C2 or TLC, as the case may be, hereunder, (ii) executes and
delivers to Christiana and Weatherford an agreement agreeing to be bound by each
and every provision of this Agreement as if it were C2 or TLC, as the case may
be,and (iii) has a net worth on a pro forma basis after giving effect to the
acquisition or business combination equal to or greater than that of C2 or TLC,
as the case may be, on a consolidated basis.
 
     7.  Miscellaneous.
 
     7.1  Waiver and Amendment. Any provision of this Agreement may be waived at
any time by the party that is entitled to the benefits thereof. This Agreement
may not be amended or supplemented at any time, except by an instrument in
writing signed on behalf of each party hereto, provided that this Agreement may
be amended only as may be permitted by the laws that govern Weatherford, TLC,
Christiana and C2. The waiver by any party hereto of any condition or of a
breach of another provision of this Agreement shall not operate or be construed
as a waiver of any other condition or subsequent breach. The waiver by any party
hereto of any of the conditions precedent to its obligations under this
Agreement shall not preclude it from seeking redress for breach of this
Agreement other than with respect to the condition so waived.
 
     7.2  Arbitration. Any disputes, claims or controversies connected with,
arising out of, or related to, this Agreement and the rights and obligations
created herein, or the breach, validity, existence or termination hereof, shall
be settled by Arbitration to be conducted in accordance with the Commercial
Rules of Arbitration of the American Arbitration Association, except as such
Commercial Rules may be changed by this Section 7.2. The disputes, claims or
controversies shall be decided by three independent arbitrators (that is,
arbitrators having no substantial economic or other material relationship with
the parties), one to be appointed by TLC and C2 and one to be appointed by
Weatherford within fourteen days following the submission of the claim to the
parties hereto and the third to be appointed by the two so appointed within five
days. Should either party refuse or neglect to join in the timely appointment of
the arbitrators, the other party shall be entitled to select both arbitrators.
Should the two arbitrators fail timely to appoint a third arbitrator, either
party may apply to the Chief Judge of the United States District Court for the
Southern District of Texas to make such appointment. The arbitrators shall have
ninety days after the selection of the third arbitrator within which to allow
discovery, hear evidence and issue their decision or award and shall in good
faith attempt to comply with such time limits; provided, however, if two of the
three arbitrators believe additional time is necessary to reach a decision, they
may notify the parties and extend the time to reach a decision in thirty day
increments, but in no event to exceed an additional ninety days. Discovery of
evidence shall be conducted expeditiously by the Parties, bearing in mind the
parties desire to limit discovery and to expedite the decision or award of the
arbitrators at the most reasonable cost and expense of the parties. Judgment
upon an award rendered pursuant to such Arbitration may be entered in any court
having jurisdiction, or application may be made to such court for a judicial
acceptance of the award, and an order of enforcement, as the case may be. The
place of Arbitration shall be Houston, Texas. The decision of the arbitrators,
or a majority thereof, made in writing, shall be final and binding upon the
parties hereto as to the questions submitted, and each party shall abide by such
decision. Notwithstanding the provisions of this Section 7.2, neither party
shall be prohibited from seeking injunctive relief pending the completion of any
arbitration. The costs and expenses of the arbitration proceeding, including the
fees of the arbitrators and all costs and expenses, including legal fees and
witness fees, incurred by the prevailing party, shall be borne by the losing
party.
 
Solely for purposes of injunctive relief, orders in aid of arbitration and entry
of the arbitrator's award:
 
     (a) each of the parties hereto irrevocably consents to the non-exclusive
jurisdiction of, and venue in, any state court located in Harris County, Texas
or any federal court sitting in the Southern District of Texas in any suit,
action or proceeding seeking injunctive relief, arising out of or relating to
this Agreement or any of the other agreements contemplated hereby and any other
court in which a matter that may result in a claim for
 
                                      B-10
<PAGE>   186
 
indemnification hereunder by a Weatherford Indemnified Party may be brought with
respect to any claim for indemnification by a Weatherford Indemnified Party;
 
     (b) each of the parties hereto waives, to the fullest extent permitted by
law, any objection that it may now or hereafter have to the laying of venue of
any suit, action or proceeding seeking injunctive relief, orders in aid of
arbitration or entry of an arbitration arising out of or relating to this
Agreement or any of the other agreements contemplated hereby brought in any
state court located in Harris County, Texas or any federal court sitting in the
Southern District of Texas or any other court in which a matter that may result
in a claim for indemnification hereunder by a Weatherford Indemnified Party may
be brought with respect to any claim for indemnification by a Weatherford
Indemnified Party, and further irrevocably waive any claim that any such suit,
action or proceeding brought in any such court has been brought in an
inconvenient forum; and
 
     (c) each of the parties hereto irrevocably designates, appoints and
empowers CT Corporation System, Inc. and any successor thereto as its designee,
appointee and agent to receive, accept and acknowledge for and on its behalf,
and in respect of its property, service of any and all legal process, summons,
notices and documents which may be served in any suit, action or proceeding
arising out of or relating to this Agreement or any of the other agreements

     assets.
 
     6.06  Notice. Notice of any special meeting shall be given at least five
business days prior thereto by written notice delivered personally or mailed to

mail, so addressed, with postage thereon prepaid. If notice is given by
telegram, such notice shall be deemed to be delivered when the telegram is
delivered to the telegraph company. Any Manager or Member may waive notice of
any meeting. The attendance of a Manager or Member at a meeting shall constitute
a waiver of notice of such meeting, except where a Manager or Member attends a
meeting for the express purpose of objecting to the transaction of any business
because the meeting is not lawfully called or convened. Neither the business to
be transacted at, nor the purpose of, any regular or special meeting of the
Managers need be specified in the notice or waiver of notice of such meeting.
 
     6.07  Manner of Acting. The act of the majority of the Managers present at
a meeting at which a quorum is present shall be the act of the Board of Managers
("Manager Approval").
 
     6.08  Vacancies. Subject to the provisions of Section 6.01 hereof, any
vacancy occurring in the Board of Managers shall be filled by the affirmative
vote of a majority of the remaining Managers through less than a quorum of the

unexpired term of his predecessor in office.
 
     6.09  Presumption of Assent. A Manager of the Company who is present at a
meeting of the Board of Managers at which action on any corporate matter is
taken shall be presumed to have assented to the action taken unless such
Manager's dissent shall be entered into the minutes of the meeting or unless
such Manager shall file his or her written dissent to such action with the
person acting as the secretary of the meeting before the adjournment thereof or
shall forward such dissent by registered mail to the secretary of the Company
immediately after the adjournment of the meeting. Such right to dissent shall
not apply to a Manager who voted in favor of such action.

     6.11 Action Without Meeting. Any action required or permitted by this
Operating Agreement or by law to be taken at a meeting of the Board of Managers
or by the Members may be taken without a meeting if a written consent or
consents, describing the action so taken, is signed by all of the Managers or
Members, respectively, entitled to vote with respect to the subject matter
thereof and delivered to the Company for inclusion in the Company's records.
 
     6.12  Telephonic Meetings. Except as herein provided and notwithstanding
any place set forth in the notice of the meeting or this Operating Agreement,

or special meetings by, or through the use of, any means of communication by
which (a) all participants may simultaneously hear each other, such as by
conference telephone, or (b) all communication is immediately transmitted to
each participant, and each participant can immediately send messages to all
other participants. If a meeting is conducted by such means, then at the
commencement of such meeting, the presiding person shall inform the
participating Managers and Members that a meeting is taking place at which
official business may be transacted. Any participants in a meeting by such means
shall be deemed present in person at such meeting. Notwithstanding the
foregoing, no action may be taken at any meeting held by such means on any
particular matter, which the presiding person determines, in his or her sole
discretion, to be inappropriate under the circumstances for action at a meeting
held by such means. Such determination shall be made and announced in advance of
such meeting.
 
     6.13  Reliance by Third Parties. Any person dealing with the Company, other
than a Member, may rely on the authority of the Board of Managers and any
officer of the Company in taking any action that is in the name of the Company
without inquiry into the provisions of this Operating Agreement or compliance
therewith. Every instrument purporting to be the action of the Company and
executed by the Board of Managers or any officer of the Company shall be
conclusive evidence in favor of any person relying thereon or claiming
thereunder that, at the time of delivery thereof, this Operating Agreement was
in full force and effect and that the execution and delivery of that instrument
is duly authorized by the Company.
 
     6.14  Filing of Documents. The Board of Managers shall file or cause to be
filed all certificates or documents as may be determined by the Board of
Managers to be necessary or appropriate for the formation, continuation,
qualification, and operation of a limited liability company in the State of
Delaware and any other state in which the Company may elect to do business. To
the extent that the Board of Managers determines the action to be necessary or
appropriate, the Board of Managers shall do all things to maintain the Company
as a limited liability company under the laws of the State of Delaware and any
other state in which the Company may elect to do business.
 
     6.15  Limitation on Liability; Indemnification. No Manager, Member or
officer of the Company shall be liable, responsible, or accountable in damages
or otherwise to the Members or the Company for any act or omission in connection
with the business of the Company if the officer acted (i) in good faith and in a
manner he or she reasonably believed to be within the scope of the authority
granted to him or her by this Operating Agreement and (ii) in the best
interests, or not opposed to the best interests, of the Company; provided that
the Manager or officer shall not be relieved from liability for any claim, issue
or matter as to which the officer shall have been finally adjudicated to have
committed fraud or willful misconduct. Subject to this limitation in the case of
such adjudication of liability, the Company shall indemnify the Managers, to the
fullest extent permitted under the Act, against any losses, judgements,
liabilities, and expenses (including, without limitation, reasonable attorney's
fees) incurred by reason of any act or omission in connection with the business
of the Company.
 
     6.16  Delegation to Members or Representatives of Members. The Board of
Managers may, from time to time, fill the offices of president, vice president,
secretary and treasurer. The Board of Managers may appoint such other officers
and assistant officers as they deem necessary. Unless the Board of Managers
decide otherwise, if the title is one commonly used for officers of a business
corporation, the assignment of such title shall constitute the delegation of the
authority and duties that are normally associated with that office, as set forth
below, subject to any specific delegation of authority and duties made pursuant
to the first sentence of this Section 6.16. Any number of titles may be held by
the same person. Any delegation pursuant to this

          (a) President. The President shall be the principal executive officer
     of the Company and, subject to the direction of the Board of Managers,
     shall in general supervise and control the day-to-day operations of the
     Company. The President shall preside at all meetings of the Board of
     Managers. He or she shall have authority, subject to the terms of this
     Operating Agreement and such rules as may be prescribed by the Board of
     Managers, to appoint such agents and employees of the Company as he or she
     shall deem necessary, to prescribe their powers, duties and compensation,
     and to delegate authority to them. Such agents and employees shall hold
     office at the discretion of the President. He or she shall have authority
     to sign, execute, and acknowledge, on behalf of the Company, all deeds,
     mortgages, bonds, stock certificates, contracts, leases, reports, and all

     provided by the Board of Managers, he or she may authorize any Vice
     President or other officer or agent of the Corporation to sign, execute,
     and acknowledge such documents or instruments in his or her place and
     stead. In general, he or she shall perform all duties incident to the
     office of the President and such other duties as may be prescribed by the
     Board of Managers from time to time.
 
          (b) The Vice President. In the absence of the President or in the
     event of the President's death, inability or refusal to act, or in the
     event for any reason it shall be impracticable for the President to act
     personally, the Vice President (or in the event there be more than one vice
     President, the Vice Presidents in the order designated by the Board of
     Managers, or in the absence of any designation, then in the order of their
     election or appointment) shall perform the duties of the President, and
     when so acting, shall have all the powers of and be subject to all the
     restrictions upon the President. Any Vice President shall perform such
     other duties and have such authority as from time to time may be delegated
     or assigned to him or her by the President or by the Board of Managers. The
     execution of any instrument of the Company by any Vice President shall be
     conclusive evidence, as to third parties, of his or her authority to act in
     the stead of the President.
 
          (c) The Secretary. The Secretary shall (i) keep minutes of the

of their time and efforts as is reasonably necessary to perform their duties and
responsibilities to the Company.

    ASSIGNMENT, TRANSFER AND REPURCHASE OF MEMBER'S UNITS AND DISASSOCIATION
 
     7.01  Assignment and Transfer.
 
          (a) General Restrictions on Transfers. Except as otherwise provided
     herein, a Member may not Transfer any Unit without the prior written
     consent of the Board of Managers. Any Transfer, attempted Transfer, or
     purported Transfer in violation of this Operating Agreement's terms and
     conditions shall be null and void. Notwithstanding the foregoing:
 
             (i) C2, Inc. may transfer its interest in the Company if it
        complies with Section 5.2 of the Purchase Agreement.
 
             (ii) C2, Inc. may pledge and assign its interest to Christiana and
        Christiana may effect a Transfer of C2, Inc.'s Units pursuant to any
        action taken with respect to any security interest granted to it by C2,
        Inc.
 
             (iii) Christiana may transfer its Units to any transferee that is
        an affiliate of Christiana or C2, Inc. if such party agrees in writing
        to be bound by the provisions of this Operating Agreement.
 
             (iv) At any time after the fifth anniversary of the date of this
        Operating Agreement, Christiana shall have the option (but shall not be
        required) to sell to C2, Inc. or the Company at Christiana's option, and
        C2, Inc. and the Company, as applicable, shall be required to purchase,
        all (but not less than all) of Christiana's interests in the Company for
        a price equal to $7.0 million. To exercise this option, Christiana shall
        provide notice in writing to C2, Inc. or the Company, as applicable, of
        such election. The closing of any purchase pursuant to this subsection
        shall occur within 60 days of notice to C2, Inc. or the Company, as
        applicable. The price required to be paid by C2, Inc. or the Company, as
        applicable, pursuant to this subsection shall be paid in cash. The
        rights contained in this subsection shall expire on the date one year
        after the fifth anniversary of the date of this Operating Agreement.
 
             (v) At any time after the fifth anniversary of the date of this
        Operating Agreement, Christiana may transfer any or all of its Units in
        the Company to any person without the prior consent of the Board of
        Managers, provided, however, that in order to effect any such Transfer,
        Christiana must provide C2, Inc. with a copy of the terms of the
        proposed Transfer (the "Transfer Notice"). C2, Inc. shall have a right
        of first refusal to purchase such Units for the same price and on the
        same terms set forth in the Transfer Notice. Such rights shall be
        exercised by C2, Inc. sending an appropriate notice to Christiana within
        60 days after receipt of the Transfer Notice. The closing shall then be
        held 30 days after C2, Inc. sends its notice to Christiana.
 
          (b) Involuntary Transfer.
 
             (i) Notice of Involuntary Transfer. In the event of an Involuntary
        Transfer of a Unit, the Transferor or the Involuntary Transferee shall
        immediately deliver a Notice of Involuntary Transfer to the Company.
        During the 90-day period beginning on the earlier of (i) the date of
        receipt by the Company of the Notice of Involuntary Transfer or (ii) the
        date that the Company provides a notice to the Involuntary Transferee
        and the Members that the Company is aware of the Involuntary Transfer,
        the Company shall have the option to purchase the Units that are subject
        to the Involuntary Transfer. The purchase price shall be an amount equal
        to the book value attributable to those Units, as determined by the
        Company's accountants, calculated as of the last day of the calendar
        quarter immediately preceding the date of the Involuntary Transfer. The
        purchase price shall be payable pursuant to the terms of payment set
        forth in the applicable provisions of Section 7.01(e) below.
        Notwithstanding the foregoing, in the case of a Member that is an
        entity, the option described above in this Section 7.01(b) shall not
        apply with respect to an Involuntary Transfer of Units resulting from a
        merger of such Member into another entity if the proportionate interest
        owned by each person who owns, directly or indirectly, an ownership
        interest in such other entity immediately after the merger is
        substantially the same as the proportionate interest owned, directly or
        indirectly, by such person in the Member immediately before the merger.
 
                                      C-10
<PAGE>   200
 
             (ii) Acceptance of Offer. The Company shall exercise any such
        option by delivering a written notice to the Transferor (if the
        Transferor is still in existence) and the Involuntary Transferee within
        such 90-day period, which notice shall specify a closing date, occurring
        within 30 days after the end of such 90-day period, for the purchase by
        the Company.
 
             (iii) Status of Involuntary Transferee. Regardless of whether the
        Company exercises such option or closes such purchase, the Involuntary
        Transferee shall not be considered to be a Member, for any period of
        time, as a result of the Involuntary Transfer (and the rights of the
        Involuntary Transferee shall be as described in Section 7.01(c)), unless
        all the Nontransferring Members have delivered (within such 90-day
        period) their written consent, which consent may be withheld in the sole
        and absolute discretion of the Nontransferring Members, to treating the
        Involuntary Transferee as a Member.
 
          (c) Effect of Transfers. Until an Involuntary Transferee is considered
     a Member, if ever, pursuant to the applicable provisions of this Article
     VII, the Units transferred to an Involuntary Transferee shall be considered
     in all respects as Units held by the Transferor for purposes of this
     Operating Agreement except for those provisions relating to the economic
     rights associated with such Units, the nonmanagement provisions of which
     will apply to the Involuntary Transferee as though the Involuntary
     Transferee held the Units. Except as otherwise provided in this Operating
     Agreement, any actions that a Member takes or would be entitled to take
     with respect to Units, including, without limitation, votes, consents,
     offers, sales, purchases, options, or other deeds taken pursuant to this
     Operating Agreement, shall be taken by the Member for its Involuntary
     Transferees with respect to the Units held by those Involuntary
     Transferees. This Section 7.01(c) shall constitute an irrevocable and
     absolute proxy and power of attorney granted by each Involuntary Transferee
     to its Transferor to (1) take such actions on behalf of the Involuntary
     Transferee without any further deed than the taking of the action by the
     Member, and (2) sign any document or instrument evidencing such action for
     or on behalf of the Involuntary Transferee relating to the Units held by
     the Involuntary Transferee.
 
          (d) Time and Place of Closing. Except as otherwise agreed by the
     Company, the closing of any Involuntary Transfer (or purchase by the
     Company) pursuant to this Article VII shall occur at the Company's
     principal office on such day as the Company shall select pursuant to the
     provisions of this Article VII. The Company shall notify the Transferor and
     the Involuntary Transferee in writing of the exact date and time of closing
     at least 10 days before the closing date.
 
          (e) Transfer and Payment of Purchase Price. At the closing, the
     Transferor shall deliver the Units that are subject to the Involuntary
     Transfer (or purchase or redemption by the Company) free and clear of any
     liens, security interests, encumbrances, charges, or other restrictions
     (other than those created pursuant to this Operating Agreement), together
     with all such instruments or documents of conveyance as shall be reasonably
     required. If not otherwise provided pursuant to this Section 7.01 and the
     Notice of Involuntary Transfer, or otherwise agreed, the price for any
     Units to be purchased or redeemed by the Company shall be paid by certified
     or bank cashier's check.
 
     7.02  Disassociation. A person ceases to be a Member of the Company upon
the occurrence of, and at the time of, any event of disassociation defined under
the Act.
 
     7.03  Restraining Order. In the event that any Member shall at any time
Transfer or attempt to Transfer its Units in violation of the provisions of this
Operating Agreement and any rights hereby granted, then the other Members and
the Company shall, in addition to all rights and remedies at law and in equity,
be entitled to a decree or order restraining and enjoining such Transfer, and
the offending Member shall not plead in defense thereto that there would be an
adequate remedy at law; it being hereby expressly acknowledged and agreed that
damages at law will be an inadequate remedy for a breach or threatened breach of
the violation of the provisions concerning transfer set forth in this Operating
Agreement.

                           DISSOLUTION AND WINDING UP
 
     8.01  Dissolution. The Company shall be dissolved upon the happening of any
of the following:
 
          (a) By Member Approval to dissolve the Company;
 
          (b) The Company being adjudicated insolvent or bankrupt; or
 
          (c) Entry of a decree of judicial dissolution.
 
     8.02  Winding Up and Liquidation. Upon a dissolution of the Company, the
Members shall by Member Approval select a liquidator (the "Liquidator"). The
Liquidator shall liquidate as much of the Company's assets in its discretion,
and shall do so as promptly as is consistent with obtaining fair value for them,
and shall apply and distribute the assets of the Company in accordance with the
following:
 
          (a) First, to the payment and discharge of all of the Company's debts
     and liabilities to creditors of the Company regardless of whether they are
     Members, including, without limitation, the unpaid principal balance (and
     any interest thereon) of any loan made by a Member; and
 
          (b) Second, to the Members in accordance with their Capital Accounts,
     after giving effect to all contributions, distributions and allocations for
     all periods.
 
     8.03  Compliance With Timing Requirements of Regulations. In the event the
Company is "liquidated" within the meaning of Section 1.704-1(b)(2)(ii)(g) of
the Treasury Regulations, distributions shall be made pursuant to this Article
IX by the end of the fiscal year in which such liquidation occurs, or if later,
within ninety (90) days of such liquidation. Distributions pursuant to the
preceding sentence may be distributed to a trust established for the benefit of
the Members for the purposes of liquidating Company assets, collecting amounts
owed to the Company, and paying any contingent or unforeseen liabilities or
obligations of the Company or of the Members arising out of or in connection
with the Company. The assets of any such trust shall be distributed to the
Members from time to time, in the reasonable discretion of the Members in the
same proportions as the amount distributed to such trust by the Company would
otherwise have been distributed to the Members pursuant to this Operating
Agreement; provided, however, such trust may only be created if the Company has
received an opinion from counsel, which is generally recognized as being capable
and qualified in the area of federal income taxation, that such trust will not
be classified as an association which would be taxed as a corporation for
federal income tax purposes.
 
                                   ARTICLE IX

to the Company if different methods were followed.

          (b) Section 754 Election. In the event of a transfer of all or part of
     the interest of a Member in the Company, at the request of the transferee,
     the Board of Managers may, in its sole discretion, cause the Company to
     elect, pursuant to Code Section 754, or the corresponding provision of
     subsequent law, to adjust the basis of the Company property as provided by

Board of Directors

Gentlemen:
 
     We understand that Weatherford International, Inc., previously known as
EVI, Inc. ("Weatherford"), Christiana Acquisition, Inc., a wholly owned
subsidiary of Weatherford ("Sub"), Christiana Companies, Inc. ("Christiana"),
and C2, Inc., ("C2"), propose to enter into an Amendment, substantially similar
to the draft dated October 7, 1998 (the "Amendment") to the Agreement and Plan
of Merger dated December 12, 1997, as amended (together with the Amendment, the
"Amended Merger Agreement"), which provides, among other things, for the merger
(the "Merger") of Sub with and into Christiana. Pursuant to the Merger,
Christiana will become a wholly owned subsidiary of Weatherford and each issued
and outstanding share of common stock, par value $1.00 per share, of Christiana
(the "Christiana Common Stock"), other than shares held directly or indirectly
by Christiana, will be converted into the right to receive (i) shares of common
stock, par value $1.00 per share, of Weatherford (the "Weatherford Common
Stock") equal to the number of shares of Weatherford Common Stock held by
Christiana at the time of the Merger divided by the number of outstanding shares
of Christiana Common Stock, and (ii) a certain cash amount per share equal to
the amount of cash held by Christiana in excess of its accrued unpaid taxes, the
value of certain tax benefits and fixed liabilities at the time of the Merger
divided by the number of outstanding shares of Christiana Common Stock, all
subject to adjustment as described in the Amended Merger Agreement.
 
   
     We further understand that in a separate but related transaction,
Weatherford, Christiana, C2 and Total Logistic Control, LLC ("Logistic"), have
entered into an Agreement, dated December 12, 1997, as amended (the "Logistic
Agreement" and together with the Amended Merger Agreement, the "Agreements"),
which provides, among other things, as a condition to the Merger, for the sale
by Christiana to C2 of 667 Membership Units (two-thirds of the outstanding
interest) in Logistic for $10,666,667 in cash and the assumption by C2 of
certain Assumed Liabilities (as defined in the Logistic Agreement) (the
"Logistic Sale"). In addition, the Logistic Agreement also provides for the
indemnification by C2 and Logistic of Weatherford and Christiana and certain
other parties in certain circumstances. The terms and conditions of the Merger
and the Logistic Sale are more fully set forth in the Agreements.

     You have asked for our opinion as to whether the consideration to be paid
by Weatherford pursuant to the Amended Merger Agreement is fair from a financial
point of view to Weatherford.
 
     For purposes of the opinion set forth herein, we have:
 
          (i) reviewed certain publicly available financial statements and other
     information of Weatherford and Christiana;
 
   
          (ii) reviewed certain internal financial statements and other
     financial and operating data concerning Weatherford, Christiana and
     Logistic prepared by the managements of Weatherford, Christiana and
     Logistic, respectively;
    
 
   
          (iii) analyzed certain financial projections concerning Weatherford,
     Christiana and Logistic prepared by the managements of Weatherford,
     Christiana and Logistic, respectively;
    
 
   
          (iv) discussed the past and current operations and financial condition
     and the prospects of Weatherford, Christiana and Logistic with senior
     executives of Weatherford, Christiana and Logistic, respectively;
    
 
          (v) analyzed the pro forma impact of the Merger on Weatherford's
     earnings per share;
 
          (vi) reviewed the reported prices and trading activity for Weatherford
     Common Stock and Christiana Common Stock;
 
          (vii) reviewed the Agreements and certain related documents;
 
          (viii) reviewed a draft letter dated as of October 7, 1998
     substantially similar to the letter to be provided to the Boards of
     Directors of Weatherford and Christiana by Arthur Andersen LLP, regarding
     the tax treatment of the Merger;
 
          (ix) discussed and reviewed with Weatherford and Fulbright & Jaworski
     L.L.P. the results of their legal and environmental due diligence; and
 
          (x) performed other such analyses and considered such other factors as
     we have deemed appropriate.
 
   
     We have assumed and relied upon without independent verification the
accuracy and completeness of the information reviewed by us for the purposes of
this opinion. With respect to the financial projections, we have assumed that
they have been reasonably prepared on bases reflecting the best currently
available estimates and judgments of the future financial performances of
Weatherford, Christiana and Logistic. We have not made any independent valuation
or appraisal of the assets or liabilities of Weatherford, Christiana or
Logistic, except, that we have received the draft letter of Arthur Andersen LLP
referred to as item (viii) above and the verbal report concerning certain legal
and environmental due diligence analyses performed by Weatherford and Fulbright
& Jaworski L.L.P. referred to as item (ix) above and we have relied, without
independent verification, upon such items for purposes of this opinion. In
addition, we have assumed the Logistic Sale will be consummated prior to or
simultaneously with the Merger in accordance with the terms set forth in the
Logistic Agreement including any terms and conditions relating to
indemnification and that the Merger will be consummated in accordance with the
terms set forth in the Amended Merger Agreement including that all material
conditions to closing have been satisfied and not waived. We have also assumed
that the Merger shall qualify as a reorganization within the meaning of Section
368(a) of the Internal Revenue Code of 1986, as amended. In arriving at our
opinion, we were not authorized to consider, and did not consider, any
alternative transaction or transaction structure. Our opinion is necessarily
based on economic, market and other conditions as in effect on, and the
information made available to us as of, the date hereof.
    
 
     It is understood that this letter is for the information of the Board of
Directors of Weatherford and may not be used for any other purpose without our
prior written consent, provided however that we consent to the inclusion of our
opinion in any filing made by Weatherford with the Securities and Exchange
Commission in connection with the Merger. In addition, we provide no advice or
opinion as to how holders of Weatherford Common Stock should vote at the
shareholders' meeting held in connection with the Merger.

     We have been engaged solely to provide this opinion to the Board of
Directors of Weatherford in connection with this transaction and have received a
fee for our services. In the past, Morgan Stanley & Co. Incorporated and its
affiliates have provided financial advisory and financing services for
Weatherford and have received fees for the rendering of these services.
 
     Based on and subject to the foregoing, we are of the opinion on the date
hereof that the consideration to be paid by Weatherford pursuant to the Amended
Merger Agreement is fair from a financial point of view to Weatherford.
 
                                     Very truly yours,

Gentlemen:
 
   
     We understand that Christiana Companies, Inc., a Wisconsin corporation (the
"Company" or "CST"), Weatherford International, Inc. (formerly known as EVI,
Inc.), a Delaware corporation ("Weatherford"), Christiana Acquisition Inc., a
Wisconsin corporation and a wholly-owned subsidiary of Weatherford (the
"Acquisition Sub"), and C2, Inc., a Wisconsin corporation ("C2") and a wholly
owned subsidiary of Lubar & Co. Incorporated ("Lubar"), have proposed to enter
into an Amended and Restated Agreement and Plan of Merger (the "Agreement").
Pursuant to the Agreement, the Acquisition Sub shall merge with and into CST
(the "Merger"). In the Merger, each outstanding share of CST common stock, par
value $1.00 per share (the "CST Common Stock"), will be converted into the right
to receive a number of shares of Weatherford common stock, par value $.01 per
share (the "Weatherford Common Stock") equal to the number of shares of
Weatherford Common Stock held by CST at the effective time of the merger (the
"Effective Time") divided by the number of shares of CST Common Stock
outstanding immediately prior to the Effective Time and a cash payment (the
"Cash Payment") determined pursuant to the provisions of section 1.7(e) of the
Agreement. The Agreement is conditioned upon, among other matters, the sale by
CST of two-thirds of its interest in Total Logistic Control, LLC, a Delaware
limited liability company and a wholly-owned subsidiary of CST ("TLC"), to C2
for $10,666,667 in cash (the "Acquisition"), pursuant to an Acquisition
Agreement, dated as of December 12, 1997, as amended on May 26, 1998(as so
amended, the "Acquisition Agreement"). Pursuant to the Agreement, CST is
required to purchase shares of Weatherford Common Stock (the "Weatherford Common
Stock Purchases") (a) prior to the date the Company's proxy statement in
connection with the special stockholders meeting to be convened to consider the
Merger is mailed to the Company's stockholders for an aggregate cost of
$10,000,000 and, (b) after approval by the Company's stockholders of the Merger,
if necessary to qualify the merger as a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended, an additional
number of shares of Weatherford's Common Stock for an aggregate cost of
$5,000,000. In addition, we understand that C2 and Sheldon Lubar, a stockholder
of CST, have entered into an agreement dated December 22, 1997 and as amended on
January 30, 1998 (as so amended, the "C2 Agreement") pursuant to which C2 has
agreed that, at the election of each and any stockholder of CST, such
stockholder may purchase from C2 a number of shares of C2 common stock, par
value $1.00 per share (the "C2 Common Stock"), representing at least the same
proportionate ownership interest in C2 as such stockholder held in CST
immediately prior to the effective time of the Merger at the same price as the
C2 Common Stock will be acquired by Lubar and its affiliates, (the "C2 Optional
Purchase" and together with the Acquisition and the Merger, the "Transaction").
    
 
     You have requested our opinion as to the fairness of the Transaction from a
financial point of view to the stockholders of the Company.

     10, 1998, of the Agreement and a draft dated October 10, 1998 of Amendment
     No. 2 to the Acquisition Agreement ("Amendment No. 2");
 
          (ii) certain publicly-available historical financial and operating
     data concerning the Company, including, but not limited to, (a) the Annual

     ended June 30, 1998, (b) the Joint Proxy Statement for the Special Meeting
     of Shareholders held on August 17, 1998; and certain financial pro-forma
     financial data prepared by CST management;
 
          (iii) certain publicly-available historical financial and operating
     data for Weatherford including, but not limited to, (a) the Annual Report

     for the Special Meeting of Shareholders held on August 17, 1998;
 
          (iv) certain information relating to TLC, including historical
     financial data for the fiscal years ended June 30, 1993 through June 30,
     1998, provided by the management of TLC;

     We have assumed, with your consent, that the draft of the Agreement and the
draft of Amendment No. 2 which we reviewed (both as referred to above) will
conform in all material respects to the definitive forms of the Agreement and
Amendment No. 2.
 
     We have met with members of the senior management of the Company and TLC to
discuss (i) the prospects for the Company's business, (ii) their estimates of
the future financial performance of the Company, (iii) the financial impact of
the Merger on CST and (iv) such other matters that we deemed relevant. We have
also visited selected CST and TLC facilities.
 
     In connection with our review and analysis and in arriving at our opinion,
we have relied upon the accuracy and completeness of the financial and other
information provided to us by the Company and by TLC, and have not undertaken
any independent verification of such information or any independent valuation or
appraisal of any of the assets or liabilities of the Company or TLC. With
respect to the financial forecasts provided to us by the Company for the Company
and by TLC for TLC, we have assumed that such forecasts (and the assumptions and
bases therefor) have been reasonably prepared and represent the respective
management's best currently available estimate as to the future financial
performance of the Company and TLC. Our opinion assumes that: (i) the Merger
will qualify as a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended; (ii) neither CST nor the Acquisition
Sub will recognize any gain or loss for federal income tax purposes as a result
of the receipt by Weatherford of CST Common Stock in exchange for Weatherford
Common Stock in the Merger; and (iii) the holders of CST Common Stock will not
recognize any gain or loss for federal income tax purposes as a result of the
receipt of Weatherford Common Stock as partial consideration for their CST
Common Stock in the Merger. Prudential

Securities has assumed that such taxes are the only relevant taxes for purposes
of the Prudential Securities Opinion other than taxes that may be applicable to
the Cash Consideration as set forth in such opinion.
 
     For purposes of our opinion, we have assumed that the stockholders of CST
at the effective time of the Merger will be legally entitled to compel
performance by C2 of the C2 Agreement in accordance with its terms in a legal
proceeding brought by such stockholders and we have further assumed that the C2
Agreement will not be amended or modified. In addition, we have assumed that all
Weatherford Common Stock Purchases will be executed in open market transactions
on a nationally recognized securities exchange or in such other transactions
having terms that are at least as favorable as would have been obtained in such
open market purchases at the time of such other transactions.
 
     Our engagement by the Company was limited to reviewing the financial terms
of the transactions described herein, and, accordingly, our opinion does not
address, nor should it be construed to address, the relative merits of the
Transaction or alternative business strategies that may be available to the
Company. In addition, this opinion does not in any manner address the prices at
which Weatherford Common Stock or C2 Common Stock will trade following
consummation of the Merger or the liquidity of the market that may exist for the
C2 Common Stock. Further, our opinion is necessarily based on economic,
financial and market conditions as they exist and can only be evaluated as of
the date hereof. For purposes of rendering this opinion, we have assumed that
the Company will not consummate the Transaction under circumstances where the
closing price of Weatherford Common Stock is less than $13.00 per share on the
closing date of the Merger.
 
     As you know, we have been retained by the Company to render this opinion in
connection with the Merger and will receive a fee for such services, the
majority of which fee is contingent upon the consummation of the Merger. In the
ordinary course of business we may actively trade the shares of CST Common Stock
and Weatherford Common Stock for our own account and for the accounts of
customers and, accordingly, may at any time hold a long or short position in
such securities.
 
     This letter and the opinion expressed herein are for the use of the
Independent Committee of the Board of Directors and the Board of Directors of
the Company. This opinion does not constitute a recommendation to the
stockholders of the Company as to how such stockholders should vote in
connection with the Merger or as to any other action such stockholders should
take regarding the Merger. This opinion may not be reproduced, summarized,
excerpted from or otherwise publicly referred to or disclosed in any manner,
without our prior written consent; except that the Company may include this
opinion in its entirety (a) in any proxy statement, or information statement
relating to the Merger sent to the Company's stockholders or (b) in a
registration statement filed under the Securities Act of 1933 with respect to
the C2 Common Stock to be issued pursuant to the C2 Optional Purchase.
 
     Based upon and subject to the foregoing, we are of the opinion that, as of
the date hereof, the Transaction is fair to the stockholders of the Company from
a financial point of view.
 
                                      Very truly yours,

Boards of Directors
Christiana Companies, Inc.
EVI, Inc. and
C2, Inc.
 
   
     This letter is furnished at the request of Christiana Companies, Inc.
("CST") regarding the proposed restructuring (the "Restructuring") of Total
Logistic Control, LLC ("TLC").
    
 
OVERVIEW
 
     We understand that CST currently holds 100% of the member interests of TLC
(the "TLC Member Interest"). Pursuant to the Restructuring, CST intends to sell
two-thirds ( 2/3) of its TLC Member Interest to a new company, C2, Inc. ("C2").
We also understand that as part of the Restructuring, CST has a put exercisable
after five years from the Restructuring (the "Put") to sell its remaining
one-third TLC Member Interests to C2.
 
     As part of the Restructuring, TLC intends to enter into a $65.0 million
revolving line of credit (the "Revolver" or "the Financing") with a group of
banks led by Firstar Bank Milwaukee, N.A. (Firstar Bank Milwaukee, N.A. and the
banks collectively referred to herein as "the Banks"). We understand that the
Financing will be used to refinance (the "Refinancing") existing debt of TLC,
and as part of the Restructuring, TLC will pay a $20.0 million dividend (the
"Dividend") to CST and repay a $3.0 million subordinated note to CST (the
"Subordinated Note"), thereby drawing an additional $23.0 million on the
Revolver over and above the amount needed for the Refinancing.
 
     We understand that there will be a number of other transactions involving
CST as well as CST and EVI, Inc. ("EVI") which are not a part of this Opinion.
 
     The transactions contemplated as a result of the Restructuring, the
Revolver, the Dividend, the Refinancing, the repayment of the Subordinated Note
and the Financing and the payment of related fees and expenses are collectively
referred to as the "Transaction".
 
SOLVENCY TESTS AND DEFINITIONS
 
     In connection with the Transaction, you have requested that we render a
written opinion (the "Opinion") addressed to the Board of Directors of CST and
EVI and C2, as to whether, assuming the Transaction has been consummated
substantially as proposed after, and giving effect to, the consummation of the
Transaction:
 
          (a) The fair value of the aggregate assets of TLC will exceed its
     respective total liabilities (including, without limitation, subordinated,
     unmatured, unliquidated, disputed and contingent liabilities);
 
                                       G-1
<PAGE>   215
 
          (b) The present fair saleable value of the aggregate assets of TLC
     will be greater than its respective probable liabilities on its debts as
     such debts become absolute and matured;
 
          (c) TLC will be able to pay its respective debts and other
     liabilities, including contingent liabilities and other commitments, as
     they mature; and
 
          (d) TLC will not have unreasonably small capital for the business in
     which it is engaged, as managements of TLC and CST have indicated such
     business is now conducted and proposed to be conducted following the
     consummation of the Transaction.
 
     For purposes of the Opinion, the following terms will have meanings set
forth below:
 
          (1) "Fair value" means the amount at which the aggregate assets would
     change hands between a willing buyer and a willing seller, within a
     commercially reasonable period of time, each having reasonable knowledge of
     the relevant facts, neither being under any compulsion to act, with equity
     to both;
 
          (2) "Present fair saleable value" means the amount that may be
     realized if the aggregate assets are sold with reasonable promptness in an
     arm's-length transaction under present conditions in a current market for
     the sale of assets of a comparable business enterprise;
 
          (3) "Contingent liabilities" of TLC means the maximum estimated amount
     of contingent liabilities which contingent liabilities have been identified
     to us by responsible officers and employees of TLC and CST, their
     respective accountants and financial advisors, and such other experts as we
     deemed necessary to consult, and valued by AAA after consultation with
     responsible officers and employees of TLC and CST, and/or such industry,
     economic and other experts as we deemed necessary to consult (the valuation
     of contingent liabilities to be computed in light of all of the facts and
     circumstances existing at the time of such valuation as an amount that can
     reasonably be expected to become an actual or matured liability), which
     contingent liabilities may not meet the criteria for accrual under
     Statement of Financial Accounting Standards No. 5 and therefore may not be
     recorded as liabilities under Generally Accepting Accounting Principles
     ("GAAP");
 
          (4) "Able to pay its debts as they mature" means that assuming the
     Transaction has been consummated as proposed (and taking into consideration
     additional borrowing capacity under TLC's Revolver) during the period
     covered July 1, 1997 through June 30, 2002 covered by the financial
     projections faxed to American Appraisal Associates, Inc. on November 17,
     1997 and prepared by CST and TLC management (the "Financial Projections"),
     TLC will have positive cash flow after paying its scheduled anticipated
     indebtedness; the realization of current assets in the ordinary course of
     business will be sufficient to pay recurring current debt, short-term debt,
     long-term debt service and other contractual obligations, including
     contingent liabilities, as such obligations mature; and the cash flow will
     be sufficient to provide cash necessary to repay TLC's long-term
     indebtedness as such debt matures; and
 
          (5) "Will not have unreasonably small capital with which to conduct
     its business" means that TLC will not lack sufficient capital for the needs
     and anticipated needs for capital of its business, including contingent
     liabilities, as management of TLC and CST have indicated it is, and
     proposed to be, conducted following the consummation of the Transaction.
 
     No representation is made herein as to the sufficiency of the above
definitions for any purpose; such definitions are used solely for setting forth
the scope of our Opinion.
 
VALUATION METHODOLOGY
 
     In rendering our Opinion, we have valued the aggregate assets of TLC, on a
going concern basis, immediately after, and giving effect to the Transaction and
the associated indebtedness incurred or remaining outstanding in connection
therewith. The valuation included the aggregate assets of the business of TLC or
total invested capital as represented by the total net working capital, tangible
plant, property and equipment, and intangible assets of the business enterprise.
We believe that this is a reasonable basis to value TLC.
                                       G-2
<PAGE>   216
 
Nothing has come to our attention that causes us to believe that TLC, after the
Transaction, is not a going concern.
 
     The determination of fair value and present fair saleable value was based
on the generally accepted valuation principles used in the market and discounted
cash flow approaches, described as follows:
 
          Market Approach -- Based on correlation of (a) current stock market
     prices of publicly held companies whose businesses are similar to that of
     TLC and premiums paid over market price by acquirors of total or
     controlling ownership in such businesses; and (b) acquisition prices paid
     for total ownership positions in business whose lines of business are
     similar to that of TLC.
 
          Discounted Cash Flow Approach -- Based on the present value of TLC's
     future debt-free operating cash flow as estimated by the management of TLC
     contained in the Financial Projections. The present value is determined by
     discounting the projected operating cash flow at a rate of return that
     reflects the financial and business risks of TLC.
 
     Our Opinion of fair value and present fair saleable value is subject to the
following conditions:
 
          (i) Any sale of TLC, including the underlying assets thereof, will be
     completed as the sale of an ongoing business entity;
 
          (ii) A "commercially reasonable period" of time means at least twelve
     months for a willing buyer and a willing seller to agree on price and
     terms, plus the time necessary to complete the sale of TLC;
 
          (iii) "Reasonable promptness" means a period of time of nine to twelve
     months for a willing buyer and a willing seller to agree on price and
     terms, plus the time necessary to complete the sale of TLC; and
 
          (iv) In determining the fair value and present fair saleable value of
     the assets of TLC, any taxes or transaction costs which may be owed by TLC
     as a result of the Transaction, other than those specifically identified in
     the Financial Projections were not considered.
 
     While we believe that TLC would be marketable as a separate business
enterprise, we have not been requested to identify, and have not identified,
potential purchasers or to ascertain the actual prices and terms of which TLC
can currently be sold. Furthermore, because the sale of any business enterprise
involves numerous assumptions and uncertainties, not all of which can be
quantified or ascertained prior to engaging in an actual selling effort, we
express no opinion as to whether TLC could actually be sold for amounts we
believe to be equivalent to the fair value and present fair saleable values.
 
FINANCIAL RESULTS AND PROJECTIONS
 
     In connection with the analysis underlying the Opinion, we were provided
historical and projected operating results (the Financial Projections as
previously defined). In addition to this information, we were provided other
operating data and information all of which has been accepted, without
independent verification, as representing a fair statement of historical and
projected results of TLC, in the opinion of the managements of TLC and CST.
However, in the course of our investigation, nothing has led us to believe that
our acceptance and reliance on such operating data and information was
unreasonable.
 
     Although we have not independently verified the accuracy and completeness
of the Financial Projections and forecasts, or any of the assumptions,
estimates, or judgments referred to therein, or the basis therefore, and
although no assurances can be given that such Financial Projections and
forecasts can be realized or that actual results will not vary materially from
those projected, nothing has come to our attention during the course of our
engagement which led us to believe that any information reviewed by us or
presented to us in connection with our rendering of the Opinion is unreasonable
in any material respect or that it was unreasonable for us to utilize and rely
upon the financial projections, financial statements, assumptions, description
of the business and liabilities, estimates and judgments of the management of
TLC and CST, and their respective counsel, accountants and financial advisors.
Our Opinion is necessarily based on business,
 
                                       G-3
<PAGE>   217
 
economic, market and other conditions as they currently exist and as they can be
evaluated by us at the date of this Opinion.
 
CONTINGENT LIABILITIES
 
     In determining the amount that would be required to pay the total
liabilities of TLC as such liabilities become absolute and mature for purposes
of Opinion (b) below, we have applied valuation techniques, including present
value analysis, using appropriate rates over appropriate periods, to the amounts
that will be required from time to time to pay such liabilities and contingent
liabilities as they become absolute and mature based on their scheduled
maturities.
 
     In the course of our investigation of identified contingent liabilities,
the areas brought to our attention by the management of TLC included, but were
not limited to: (i) the adequacy of the corporate safety and insurance program;
(ii) lawsuits or claims filed and or pending against TLC; (iii) environmental
matters; (iv) customer concentration; and (v) liabilities of TLC in connection
with the Agreement and Plan of Merger by and among EVI, Christiana Acquisition
Co., C2 and CST, anticipated to be dated and signed on December 4, 1997 (the
"Merger Agreement"), and the Proposed Agreement among EVI, CST, TLC, and C2
regarding the purchase of TLC Member Interests anticipated to be dated and
signed on December 4, 1997 (the "TLC Acquisition Agreement").
 
     We have determined that reserves for the contingent liabilities have been
made in the pro forma consolidated balance sheet as of September 30, 1997 (the
"Pro Forma Balance Sheet") prepared and furnished to us by the management of
TLC, and provisions for the ongoing expenses related to these issues have been
included with the projection of income and expenses presented in the Financial
Projections, and are considered in our valuation study as ongoing business
operating expenses. We have taken these identified contingent liabilities into
account in rendering our Opinion and have concluded that such liabilities and
ongoing expenses do not require any qualification of our Opinion. Our conclusion
is based on, among other things: (i) our review of various acquisition
transactions, including leveraged transactions and significant debt-financed
recapitalization transactions, involving corporations engaged in businesses
similar to those of TLC; (ii) the opinion of the managements of TLC and CST that
the issues concerning various lawsuits, claims and other identified contingent
liabilities will not have a material adverse effect on the financial position of
TLC; and (iii) our discussions with the managements of TLC and CST, their
accountants, consultants and counsel concerning, and our investigation of, the
various lawsuits, claims and other contingent liabilities identified to us.
 
     We have assumed that as of the effective date of the closing of the
Transaction, the total identified liabilities of TLC will be only those
liabilities set forth in its respective Pro Forma Balance Sheet and incorporated
in the Financial Projections that were prepared by TLC and CST and furnished to
us by the managements of TLC and CST and their financial advisors. In the course
of our investigation, nothing came to our attention which caused us to believe
such assumptions to be unreasonable. The Pro Forma Balance Sheet is the
unaudited Pro Forma Opening Balance Sheet for TLC as of September 30, 1997
reflecting the closing of the Transaction, as reflected in the Financial
Projections and adjusted to give effect to (a) the planned financing of the
Transaction; and (b) the application of the proceeds of the financing and
restated by us to reflect the fair value and present fair saleable value of TLC.
 
     TLC's and CST's management have represented to us, and we have relied on
the representations of the managements of TLC and CST that no adverse changes
have occurred since their preparation which would materially impact the content
of TLC's Pro Forma Balance Sheet and Financial Projections. Nothing has come to
our attention which would lead us to believe our reliance on such
representations to be unreasonable.
 
OPINION CONDITIONS AND ASSUMPTIONS
 
     We have assumed, without independent verification, that the Pro Forma
Balance Sheet and Financial Projections provided to us have been reasonably
prepared and reflect the best currently available estimates, after the
consummation of the Transaction, of the future financial results and conditions
of TLC, and that there has been no material adverse change in the assets,
financial condition, business or prospects of TLC,
                                       G-4
<PAGE>   218
 
since the date of the most recent financial statements made available to us.
Nothing has come to our attention which would lead us to believe that the
foregoing assumption is unreasonable. Further our Opinion is subject to the
following assumptions:
 
          (i) The Transaction is consummated as described herein;
 
          (ii) Pursuant to the terms and conditions of the various financing
     documents, the operating cash flow of TLC will be made available and used
     to satisfy its obligations as they mature;
 
          (iii) Our opinion of TLC's ability to be able to pay its debts and
     other liabilities including contingent liabilities and other commitments,
     as they mature, is limited to the period of time of the Financial
     Projections;
 
          (iv) Any indebtedness of TLC is permitted to be refinanced in
     conformity with common business practice to the extent consistent with
     covenants in the various Financing documents;
 
OPINION DUE DILIGENCE
 
     In connection with our Opinion, we have made such reviews, analyses and
inquiries as we have deemed necessary and appropriate under the circumstances.

     economic conditions, and capital facilities and working capital
     requirements;
 
          (iii) Reviewed audited and unaudited historical financial statements
     of TLC including income statements, balance sheets and cash flow statements
     as provided by management of and their accounting firm:

     generated data with CST and TLC including asset valuations of TLC, if any;

          (xii) Conducted such other studies, analyses and investigations as we
     deemed relevant or necessary for purposes of the Opinion.
 
OPINION
 
     Based on the foregoing, and in reliance thereon, it is our opinion as of
this date that, assuming the Transaction has been consummated as proposed,
immediately after giving effect to, the consummation of the Transaction:
 
          (a) The fair value of the aggregate assets of TLC exceed its
     respective total liabilities (including, without limitation, subordinated,
     unmatured, unliquidated, disputed and contingent liabilities);
 
          (b) The present fair saleable value of the aggregate assets of TLC is
     greater than its respective probable liabilities on its debts as such debts
     become absolute and matured;
 
          (c) TLC is able to pay its respective debts and other liabilities,
     including contingent liabilities and other commitments, as they mature; and

shareholders meeting at which shareholders are to vote on the proposed corporate
action.

shareholder entitled to dissent and obtain payment for his or her shares under

his or her entitlement unless the action is unlawful or fraudulent with respect
to the shareholder, beneficial shareholder or issuer corporation.
 
180.1303  DISSENT BY SHAREHOLDERS AND BENEFICIAL SHAREHOLDERS. (1) A shareholder
may assert dissenters' rights as to fewer than all of the shares registered in
his or her name only if the shareholder dissents with respect to all shares

     the dissent not later than the time that the beneficial shareholder asserts
     dissenters' rights.

shareholders' meeting, the meeting notice shall state that shareholders and
beneficial shareholders are or may be entitled to assert dissenters' rights

sections.
 
     (2) If corporate action creating dissenters' rights under Section 180.1302
is authorized without a vote of shareholders, the corporation shall notify, in

demand payment of the fair value of his or her shares and interest due, if any
of the following applies:
 
          (a) The dissenter believes that the amount paid under Section 180.1325

     shares or that the interest due is incorrectly calculated.
 
          (b) The corporation fails to make payment under Section 180.1325
     within 60 days after the date set under Section 180.1322 for demanding
     payment.
 
          (c) The issuer corporation, having failed to effectuate the corporate
     action, does not return the deposited certificates or release the transfer
     restrictions imposed on uncertificated shares within 60 days after the date
     set under Section 180.1322 for demanding payment.
 
     (2) A dissenter waives his or her right to demand payment under this
section unless the dissenter notifies the corporation of his or her demand under

for his or her shares. The notice shall comply with Section 180.0141.

remains unsettled, the corporation shall bring a special proceeding within 60
days after receiving the payment demand under Section 180.1328 and petition the

<PAGE>   224
 
     (2) The corporation shall bring the special proceeding in the circuit court
for the county where its principal office or, if none in this state, its
registered office is located. If the corporation is a foreign corporation
without a registered office in this state, it shall bring the special proceeding
in the county in this state in which was located the registered office of the
issuer corporation that merged with or whose shares were acquired by the foreign
corporation.
 
     (3) The corporation shall make all dissenters, whether or not residents of
this state, whose demands remain unsettled parties to the special proceeding.
Each party to the special proceeding shall be served with a copy of the petition
as provided in Section 801.14.
 
     (4) The jurisdiction of the court in which the special proceeding is
brought under sub. (2) is plenary and exclusive. The court may appoint one or
more persons as appraisers to receive evidence and recommend decision on the
question of fair value. An appraiser has the power described in the order
appointing him or her or in any amendment to the order. The dissenters are
entitled to the same discovery rights as parties in other civil proceedings.
 
     (5) Each dissenter made a party to the special proceeding is entitled to
judgment for any of the following:
 
          (a) The amount, if any, by which the court finds the fair value of his
     or her shares, plus interest, exceeds the amount paid by the corporation.
 
          (b) The fair value, plus accrued interest, of his or her shares
     acquired on or after the date specified in the dissenter's notice under
     Section 180.1322 (2)(c), for which the corporation elected to withhold
     payment under Section 180.1327.
 
180.1331  COURT COSTS AND COUNSEL FEES. (1) (a) Notwithstanding Sections 814.01

shall determine all costs of the proceeding, including the reasonable
compensation and expenses of appraisers appointed by the court and shall assess
the costs against the corporation, except as provided in par. (b).
 
     (b) Notwithstanding Sections 814.01 and 814.04, the court may assess costs
against all or some of the dissenters, in amounts that the court finds to be
equitable, to the extent that the court finds the dissenters acted arbitrarily,
vexatiously or not in good faith in demanding payment under Section 180.1328.
 
     (2) The parties shall bear their own expenses of the proceeding, except
that, notwithstanding Sections 814.01 to 814.04, the court may also assess the
fees and expenses of counsel and experts for the respective parties, in amounts
that the court finds to be equitable, as follows:
 
          (a) Against the corporation and in favor of any dissenter if the court
     finds that the corporation did not substantially comply with
     Sections 180.1320 to 180.1328.
 
          (b) Against the corporation or against a dissenter, in favor of any
     other party, if the court finds that the party against whom the fees and
     expenses are assessed acted arbitrarily, vexatiously or not in good faith
     with respect to the rights provided by this chapter.
 
     (3) Notwithstanding Sections 814.01 to 814.04, if the court finds that the
services of counsel and experts for any dissenter were of substantial benefit to
other dissenters similarly situated, the court may award to these counsel and
experts reasonable fees to be paid out of the amounts awarded the dissenters who
were benefited.

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF OFFICERS AND DIRECTORS.
 
     Under Delaware law, a corporation may include provisions in its certificate
of incorporation that will relieve its directors of monetary liability for
breaches of their fiduciary duty to the corporation, except under certain
circumstances, including a breach of the director's duty of loyalty, acts or
omissions of the director not in good faith or which involve intentional
misconduct or a knowing violation of law, the approval of an improper payment of
a dividend or an improper purchase by the corporation of stock or any
transaction from which the director derived an improper personal benefit. The
Registrant's Amended and Restated Certificate of Incorporation, as amended,
provides that the Registrant's directors are not liable to the Registrant or its
stockholders for monetary damages for breach of their fiduciary duty, subject to
the described exceptions specified by Delaware law.
 
     Section 145 of the Delaware General Corporation Law grants to the
Registrant the power to indemnify each officer and director of the Registrant
against liabilities and expenses incurred by reason of the fact that he is or
was an officer or director of the Registrant if he acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Registrant and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The Amended and Restated
By-laws of the Registrant provide for indemnification of each officer and
director of the Registrant to the fullest extent permitted by Delaware law.
Messrs. David J. Butters and Robert B. Millard, employees of Lehman Brothers
Inc. ("Lehman"), constitute two of the eight members of the Board of Directors
of the Registrant. Under the restated certificates of incorporation, as amended
to date, of Lehman and its parent, Lehman Brothers Holdings Inc. ("Holdings"),
both Delaware corporations, Messrs. Butters and Millard, in their capacity as
directors of the Registrant, are to be indemnified by Lehman and Holdings to the
fullest extent permitted by Delaware law. Messrs. Butters and Millard are
serving as directors of the Registrant at the request of Lehman and Holdings.
 
     Section 145 of the Delaware General Corporation Law also empowers the
Registrant to purchase and maintain insurance on behalf of any person who is or
was an officer or director of the Registrant against liability asserted against
or incurred by him in any such capacity, whether or not the Registrant would
have the power to indemnify such officer or director against such liability
under the provisions of Section 145. The Registrant has purchased and maintains
a directors' and officers' liability policy for such purposes. Messrs. Butters
and Millard are insured against certain liabilities which they may incur in
their capacity as directors pursuant to insurance maintained by Holdings.
 
   
     Under the terms of the Agreement dated December 12, 1997, as amended, by
and among the Registrant, Christiana Companies, Inc. ("Christiana"), Total
Logistic Control, LLC ("Logistic") and C2, Inc., Logistic and C2 have agreed to
indemnify the directors and officers of the Registrant for any liability
relating to any claim or damage by any stockholder of Christiana or Weatherford

     As permitted by Item 601(b)(4)(iii)(A) of Regulation S-K, the Registrant
has not filed with this Registration Statement certain instruments defining the
rights of holders of long-term debt of the Registrant and its subsidiaries
because the total amount of securities authorized under any of such instruments
does not exceed 10% of the total assets of the Registrant and its subsidiaries
on a consolidated basis. The Registrant agrees to furnish a copy of any such
agreements to the Securities and Exchange Commission upon request.
 
ITEM 22. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in this
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
                                      II-5
<PAGE>   230
 
   
     The undersigned Registrant hereby undertakes:
    
 
   
     (1) To file, during any period in which offers or sales are being made a
post-effective amendment to this registration statement:
    
 
   
     (i) To include any prospectus required by section 10(a)(3) of the
Securities Act of 1933;
    
 
   
     (ii) To reflect in the prospectus any facts or events arising after the
effective date of the registration statement (or the most recent post-effective
amendment thereof) which, individually or in the aggregate, represent a
fundamental change in the information set forth in the registration statement.
Notwithstanding the foregoing, any increase or decrease in volume of securities
offered (if the total dollar value of securities offered would not exceed that
which was registered) and any deviation from the low or high end of the
estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement.
    
 
   
     (iii) To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement.
    
 
   
     (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
    
 
   
     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.
    
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
of 1933 and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.
 
     The undersigned Registrant hereby undertakes that:
 
          (1) Prior to any public reoffering of the securities registered
     hereunder through use of a prospectus which is a part of this registration
     statement, by any person or party who is deemed to be an underwriter within
     the meaning of Rule 145(c), the issuer undertakes that such reoffering
     prospectus will contain the information called for by the applicable
     registration form with respect to reofferings by persons who may be deemed
     underwriters, in addition to the information called for by the other Items
     of the applicable form; and
 
          (2) Every prospectus (a) that is filed pursuant to paragraph (1)
     immediately preceding, or (b) that purports to meet the requirements of
     section 10(a)(3) of the Securities Act, and is used in connection with an
     offering of securities subject to Rule 415, will be filed as a part of an
     amendment to the registration statement and will not be used until such
     amendment is effective, and that, for purposes of determining any liability
     under the Securities Act, each such post-effective amendment shall be
     deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.
 
                                      II-6
<PAGE>   231
 
     The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
     The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

                             PARTICIPATION AGREEMENT


         THIS PARTICIPATION AGREEMENT, dated as of December 8, 1998 (this

                                   ARTICLE II

                         Purchase and Lease of Equipment

         Section 2.1 Fundings; Payment of Purchase Price and Capitalized
Transaction Costs.

         (a) Subject to the terms and conditions hereinafter set forth, and in
reliance on the representations and warranties contained herein or made pursuant
hereto, upon receipt of each Delivery Date Notice during the Interim Period,
each Lessor shall transfer to Administrative Agent on the specified Delivery
Date an amount equal to the product of the aggregate Purchase Price of the
Equipment plus all Capitalized Transaction Costs specified in such Delivery Date
Notice, multiplied by such Lessor's Commitment Percentage (each such transfer
being referred to herein as a "Funding"). In no event shall any Lessor be
required to provide funds under this Participation Agreement in an aggregate
amount exceeding such Lessor's Commitment. In no event shall Lessors be required
to provide funds under the Participation Agreement in an aggregate amount
exceeding the Appraised Value of the Equipment plus all Capitalized Transaction
Costs.

         (b) Remittances pursuant to this Section 2.1 shall be made in
immediately available federal funds by wire transfer to the account of
Administrative Agent set forth below (or as otherwise specified by
Administrative Agent to each Lessor from time to time not less than three
Business Days prior to the date of the requested Funding) and must be received
by Administrative Agent by 2:00 p.m., New York time on the applicable Delivery
Date:

                  Bank:           ABN AMRO Bank N.V.
                                          New York Branch
                                          New York, NY
                  ABA Routing #:          026009580
                  Account #:      ____________________
                  Payee:          ABN AMRO Bank N.V.
                  Reference:      Weatherford Enterra Compression Company, L.P.

         (c) Unless Administrative Agent shall have been notified in writing by
any Lessor prior to any Delivery Date that such Lessor will not make available
the amount which would constitute its Commitment Percentage of the total
Purchase Price of the Equipment plus all Capitalized Transaction Costs specified
in a Delivery Date Notice, Administrative Agent may assume that such Lessor is
making such amount available to Administrative Agent, and Administrative Agent
may, in reliance upon such assumption, take such actions as are provided for in
Section 2.2. If any Lessor (a "Defaulting Lessor") fails to make such amount
available to Administrative Agent by the required time on the Delivery Date
therefor, such Defaulting Lessor shall pay to Administrative Agent, on demand,
such amount with interest thereon at a rate equal to the daily average Federal
Funds Effective Rate for the period until such Defaulting Lessor makes such
amount immediately available to Administrative Agent. A certificate of
Administrative Agent submitted to any Lessor with respect to any amounts owing
under this Section 2.1 shall be conclusive in the absence of manifest error.

If such Defaulting Lessor's share of such Funding is not made available to
Administrative Agent by such Defaulting Lessor within three (3) Business Days of
such Delivery Date, Administrative Agent shall also be entitled to recover such
amount with interest thereon at the Alternate Base Rate plus the Applicable
Margin, on demand, from Lessee, to the extent Administrative Agent has advanced
a corresponding amount of the Funding to purchase Equipment to be leased to
Lessee.

         Section 2.2 Application of Funds; Sale and Lease of Equipment. On each
Delivery Date, upon (a) receipt by Administrative Agent of all amounts to be
paid by the Lessors pursuant to Section 2.1, and (b) satisfaction or waiver of
each of the conditions set forth in Article III, (i) Administrative Agent shall
purchase, for the benefit of the Lessors, the Equipment to be acquired on such
Delivery Date and pay the Capitalized Transaction Costs, as specified in the
relevant Delivery Date Notice delivered pursuant to Section 3.1, (ii) in
consideration therefor, Administrative Agent, on behalf of the Lessors, shall
pay, from the funds made available by the Lessors pursuant to Section 2.1, an
amount equal to the aggregate Purchase Price of the Equipment being so sold and
purchased plus all Capitalized Transaction Costs related thereto in immediately
available federal funds remitted by wire transfer to the account specified by
Lessee in the relevant Delivery Date Notice, and (iii) Administrative Agent, on
behalf of the Lessors, shall lease to Lessee the Equipment so purchased by
Administrative Agent and Lessee shall accept delivery of and lease from
Administrative Agent such Equipment pursuant to the Lease. Each Lessor shall
hold an undivided interest in the Equipment equal to such Lessor's Investment
Percentage.

         Section 2.3 Time and Place of Delivery Dates. Each Delivery Date
Closing shall take place on the Delivery Date set forth in the relevant Delivery
Date Notice, and the Initial Delivery Date Closing shall take place at the

                  (iv) in no event shall the aggregate amount advanced by the
         Lessors exceed the Total Commitment; and

obligations of Lessee to pay Fixed Rent and Variable Rent shall be treated as
payments of principal and interest, respectively. Nevertheless, Lessee
acknowledges and agrees that neither Administrative Agent nor any Lessor has
made any representations or warranties concerning the tax, accounting or legal
characteristics of the Operative Agreements and that Lessee has obtained and
relied upon such tax, accounting and legal advice concerning the Operative
Agreements as it deems appropriate. Except as specifically provided for herein

Permitted Liens, as security for the obligations of Lessee under the Operative
Agreements. Lessee shall not have any right, title or interest in the Equipment

                                    ARTICLE V

                         Representations and Warranties

         Section 5.1 Representations and Warranties of Lessee. As of the
Documentation Date and each Delivery Date, Lessee makes the representations and
warranties set forth in this Section 5.1 to Administrative Agent and each
Lessor:

         (a) Title. Administrative Agent, for the benefit of the Lessors, shall
have good and valid title to each item of Equipment listed on Schedule I to the
applicable Delivery Date Notice, and each such item of Equipment and all of the
other Collateral is free from all Liens except for Permitted Liens.

         (b) Perfection of Security Interests. No filing, recordation or
registration is necessary or advisable in order to perfect the security interest
of Administrative Agent, for the benefit of the Lessors, in the Equipment and
other Collateral referred to in the foregoing subsection (a) other than (i) as
of the applicable Delivery Date, in the case of Equipment located in the United
States, the filing or recording of financing statements under Article 9 of the
applicable UCC in the jurisdictions in the United States contemplated by Section
3.7, provided, that no financing statement filings are required by the foregoing
after the applicable Delivery Date except in the jurisdiction constituting the
Lessee's principal place of business or (ii) in the case of any Sublease, if
requested by the Agent after the occurrence and during the continuance of an
Event of Default, the delivery to Administrative Agent of the chattel paper
original of any Sublease, and upon the actions described

                                       -8-

<PAGE>   14




in the foregoing clauses (i) and (ii) the security interests in the Equipment
and the other Collateral are enforceable, properly perfected, first-priority
Liens, subject only to Permitted Liens.

         (c) Appraisal Data. The information provided by Lessee to the Appraiser
and forming the basis for the conclusions set forth in the Appraisal, taken as a
whole, was true and correct in all material respects and did not omit any
information necessary to make the information provided not materially misleading
as of the time provided.

         (d) Limited Partnership Existence. Lessee is a limited partnership duly
formed validly existing and in good standing under the laws of the State of
Delaware, and Lessee is duly qualified or licensed and in good standing as a
foreign limited partnership authorized to do business in each state where,
because of the nature of its activities or properties, such qualification or
licensing is required, except for such jurisdictions where the failure to be so
qualified or licensed would not have a Material Adverse Effect.

         (e) Limited Partnership Authority. Lessee has all requisite limited
partnership power and authority to execute, deliver, and perform its obligations
under each Operative Agreement to which it is a party.

         (f) Authorization; Non-Contravention. The execution and delivery by
Lessee of the Operative Agreements to which it is or will be a party, and the
performance by Lessee of its obligations under such Operative Agreements, have
been duly authorized by all necessary corporate action (including any necessary
stockholder action) on its part, and do not and will not: (i) violate any
provision of any law, rule or regulation or of any order, writ, judgment,
decree, determination or award, which violation or violations would have,
individually or in the aggregate, a Material Adverse Effect; (ii) violate any
provision of the certificate of limited partnership or limited partnership
agreement of Lessee; (iii) result in a breach of or constitute a default under
any indenture, loan or credit agreement, or any other agreement or instrument to
which Lessee is a party or by which Lessee or its properties may be bound or
affected, which breaches or default would have, individually or in the
aggregate, a Material Adverse Effect; or (iv) result in, or require, the
creation or imposition of any Lien of any nature upon or with respect to any of
the properties now owned or hereafter acquired by Lessee (other than the
security interest contemplated by the Lease); and Lessee is not in default under
or in violation of its certificate of limited partnership or limited partnership
agreement.

         (g) Binding Effect. Each of the Operative Agreements to which Lessee is
or will be a party constitutes the legal, valid and binding obligation of
Lessee, enforceable against Lessee, in accordance with its terms, except as
enforcement may be limited by bankruptcy, insolvency, arrangement,
reorganization, moratorium or other similar laws affecting the enforcement of
creditors' rights generally and by general principles of equity.

         (h) Absence of Litigation, etc. Other than as described in filings made
by the Guarantor with the Securities and Exchange Commission pursuant to the
Exchange Act, as of the

                                       -9-

Documentation Date, there is no litigation (including, without limitation,
derivative actions), arbitration or governmental proceedings pending or, to the
knowledge of Lessee, threatened against Lessee or Guarantor or any stockholder
or equity holder of Lessee in which there is a reasonable possibility of an
adverse decision which would have a Material Adverse Effect.

         (i) Consents, etc. No authorization, consent, approval, license or
formal exemption from, nor any filing, declaration or registration with, any
Authority, is or will be required in connection with the execution and delivery
by Lessee or Guarantor of the Operative Agreements to which it is or will be a
party, the performance by Lessee or Guarantor of its obligations under such
Operative Agreements or the ownership, leasing, operation and maintenance of the
Equipment as contemplated by the Operative Agreements, except as described in
Section 5.1(b).

         (j) Location of Offices. The principal place of business and chief
executive office (as such term is used in Article 9 of the UCC) of Lessee is
located at 5 Post Oak Park, Suite 1760, Houston, Texas 77027.

         (k) ERISA. Relying upon the accuracy of the representations in Section
5.2(a) hereof, the execution and delivery of the Operative Agreements by Lessee
and Guarantor will not involve any prohibited transaction within the meaning of
ERISA or Section 4975 of the Code.

         (l) Taxes. Lessee has filed or caused to be filed all United States
Federal and all other material tax returns that are required to be filed by
Lessee, and has paid or caused to be paid all taxes shown to be due and payable
on such returns or on any assessment received by Lessee, to the extent that such
taxes have become due and payable, except to the extent that taxes due, but
unpaid, are being contested in good faith by Lessee by appropriate action or
proceeding and has established or caused to be established reserves that are
adequate for the payment thereof in accordance with GAAP.

         (m) Compliance with Laws. The Equipment, the properties from which it
is operated and serviced and the current operation thereof and thereon do not
violate any laws, rules, regulations, or orders of any Authorities that are
applicable thereto, including, without limitation, any thereof relating to
matters of occupational safety and health or Environmental Laws, except for such
violations as would not have, individually or in the aggregate, a Material
Adverse Effect.

         (n) Disclosure. Neither this Participation Agreement, nor any offering
materials, nor the other Operative Agreements to which Lessee or Guarantor is or
will be a party nor the other documents and certificates furnished pursuant to
this Participation Agreement to Administrative Agent, Documentation Agent or the
Lessors, in connection with the transactions contemplated by this Participation
Agreement, contains any untrue statement of a material fact or omits to state a
material fact necessary in order to make the statements contained herein and
therein, in the light of the circumstances under which they were made, not
misleading as of the time furnished.

         (o) Impositions. No sales, use, excise, transfer or other tax, fee or
imposition shall result from the manufacture, transfer, lease or delivery of any
Equipment on or before any Delivery Date, except such taxes, fees or impositions

         (p) Certain Equipment Matters. Lessee is in the business of selling,

         (q) Environmental Matters.

                  (1) The Equipment being acquired on such Delivery Date does

notice will be received or is being threatened.

                  (4) No judicial proceeding or governmental or administrative
action is pending or, to the best knowledge of the Lessee, threatened, under any

knowledge, will be named as a party with respect to the Equipment being acquired

Substances at or from the Equipment being acquired on such Delivery Date, or
arising from, or generated by, operation of the Equipment being acquired on such

marks, trade names, copyrights (other than software, that is not embedded in the
Equipment, used by Lessee in connection with accounting for and maintaining the
Equipment) licenses or other intellectual property rights with respect to the
Equipment, or proprietary, patented or patentable modifications or Parts used in
connection with the Equipment, the unavailability of which would have a material
adverse effect on the current Fair Market Value of the Equipment.

         (u) Subjection to Regulation. Neither Administrative Agent,
Documentation Agent nor any Lessor will, solely by reason of entering into the
Operative Agreements or the consummation and performance of the transactions
contemplated thereby (other than upon the exercise of remedies under the Lease)
(i) be required to qualify to do business in any jurisdiction, (ii) become
subject to ongoing regulation by any Authority as a company engaged in the

ongoing regulation of its operations by any Authority (other than any taxing
Authority).

         (v) Use of Proceeds. The use of the proceeds from the transaction
contemplated by the Operative Agreements will not violate or result in any
violation of Section 7 of the Exchange Act or any regulations issued pursuant
thereto, including, without limitation, Regulations T, U and X of the Board.

         (w) Absence of Defaults. No Incipient Default or Event of Default has

GAAP applied on a consistent basis and fairly present the financial condition of
Guarantor and its consolidated Subsidiaries at the dates thereof and the
consolidated results of their operations for the periods covered thereby. There
are no liabilities, contingent or otherwise, known to Lessee or Guarantor, not
disclosed in such financial statements as footnotes that individually, or in the
aggregate, would have a Material Adverse Effect.


                                      -12-

<PAGE>   18




         (aa) Private Offering. Neither Lessee nor Guarantor, nor anyone acting
on behalf of either of them, has taken or will take any action which will
subject the issue and sale of any interest being acquired by Administrative
Agent or the Lessors under the Operative Agreements to the requirements of
Section 5 of the Securities Act, and, assuming the truth and accuracy of the
representations set forth in Section 5.2(b), the issuance, sale and delivery of
such interests under the circumstances contemplated by this Agreement do not
require the registration of such interests under the Securities Act or the
qualification of any of the Operative Agreements under the Trust Indenture Act
of 1939, as amended.

         (bb) Brokers, etc. Neither Guarantor nor Lessee has engaged or
authorized any broker, finder, investment banker or other third party to act on
its behalf, directly or indirectly, as a broker, finder, investment banker,
administrative agent or in any other like capacity in connection with any of the
Operative Agreements or the transactions contemplated thereby. Lessee shall be
responsible for, and shall indemnify, defend and hold Administrative Agent and
each Lessor harmless from and against any and all claims, liabilities or demands
by any Person for broker's, finder's, investment banker's or administrative
agent's fees, commissions or other entitlements with respect to the Operative
Agreements and the transactions contemplated thereby (except to the extent
arising from a breach of Sections 5.2(c) or 5.3(f)).

         (cc) Subsidiaries. Lessee has no Subsidiaries.

         (dd) Year 2000 Matters. The Guarantor has developed a plan to ensure
that the systems of the Guarantor and its Material Subsidiaries, including the
Lessee, are compliant in all material respects with the requirements to process
transactions in the year 2000. The Guarantor and its Material Subsidiaries plan
to achieve year 2000 compliance through a combination of upgrading to new
releases of existing software and replacement of existing software with new
fully compliant systems by mid-1999. The expenses and capital expenditures of
the Guarantor and its Material Subsidiaries associated with achieving year 2000
compliance would not reasonably be expected to have a Material Adverse Effect.
The Guarantor and its Material Subsidiaries are currently gathering information
from their key suppliers, vendors and financial institutions regarding year 2000
compliance.

         (ee) Solvency. Lessee is not insolvent (as defined in Section 101 (29)
of Title 11 of the United States Code) and will not be rendered so insolvent as
a result of the transactions contemplated hereby or referred to herein.

         Section 5.2 Representations and Warranties of Lessors. Each Lessor
hereby represents and warrants severally but not jointly to the other
Participants as set forth in this Section 5.2.

with the assets of an "employee benefit plan" (as defined in Section 3(3) of
ERISA) which is subject to Title I of ERISA, or a "plan" (as defined in Section
4975(e)(1) of the Code).

         (b) Investment. The interest being acquired by such Lessor under the
Operative Agreements is being acquired for its own account, without any view to
the distribution thereof or any interest therein, provided that such Lessor
shall be entitled to assign, transfer or convey its interest in accordance with
Section 11.8.

         (c) Brokers, etc. Such Lessor has not engaged or authorized any broker,
finder, investment banker or other third party to act on its behalf, directly or
indirectly, as a broker, finder, investment banker, administrative agent or in
any other like capacity in connection with any of the Operative Agreements or
the transactions contemplated thereby. Such Lessor shall be responsible for, and
shall indemnify, defend and hold Administrative Agent, each other Lessor and
Lessee harmless from and against any and all claims, liabilities or demands by
any Person for broker's, finder's, investment banker's or administrative agent's
fees, commissions or other entitlements with respect to the Operative Agreements
and the transactions contemplated thereby (except to the extent arising from a
breach of Sections 5.1(cc) or 5.3(f)).

         Section 5.3 Representations and Warranties of Administrative Agent. ABN
AMRO Bank N.V., in its individual capacity as Administrative Agent, hereby
represents and warrants to the other Participants as set forth in this Section
5.2.

         (a) Organization and Authority. Administrative Agent is a corporation
duly organized and validly existing in good standing under the laws of the
Netherlands and has the corporate power and authority to enter into and perform

         (b) Authorization; Binding Effect. The Operative Agreements to which
Administrative Agent is or will be a party have been or will be, on the date
required to be delivered hereby, duly authorized, executed and delivered by
Administrative Agent, and this Participation Agreement is, and such other
Operative Agreements are, or, when so executed and delivered by Administrative
Agent will be, valid, legal and binding agreements of Administrative Agent,
enforceable against Administrative Agent in accordance with their respective
terms, except as enforcement may be limited by bankruptcy, insolvency,
reorganization, arrangement, moratorium or other similar laws affecting the
enforcement of creditors' rights generally and by general principles of equity.

         (c) Non-Contravention. Neither the execution and delivery by
Administrative Agent of the Operative Agreements to which it is or will be a
party, either in its individual capacity, as Administrative Agent, or both, nor
compliance with the terms and provisions thereof, conflicts with, results in a
breach of, constitutes a default under (with or without the giving of notice or
lapse of time or both), or violates any of the terms, conditions or provisions
of: (i) the charter or governing documents of Administrative Agent; (ii) any
bond, debenture, note, mortgage, indenture, agreement, lease or other instrument
to which Administrative Agent, either in its individual capacity, as
Administrative Agent or both, is now a party or by which it or its property,
either in its individual capacity, as Administrative Agent or both, is bound or
affected, where such conflict, breach, default or violation would be reasonably
likely to materially and adversely affect the ability of Administrative Agent,
either in its individual capacity, as Administrative Agent or both, to perform

                                      -14-

of the terms, conditions or provisions of any law, rule, regulation, order,
injunction or decree of any Authority applicable to it in its individual
capacity, as Administrative Agent or both, where such conflict, breach, default
or violation would be reasonably likely to materially and adversely affect the
ability of Administrative Agent, either in its individual capacity, as
Administrative Agent or both, to perform its obligations under any Operative
Agreement to which it is or will be a party.

         (d) Absence of Litigation, etc. There is no litigation, arbitration or
governmental proceedings pending or, to the best knowledge of Administrative
Agent, threatened against it which would be reasonably likely to materially and
adversely affect Administrative Agent's ability to perform its obligations under
the Operative Agreements to which it is party.

         (e) Consents, etc. No authorization, consent, approval, license or
formal exemption from, nor any filing, declaration or registration with, any
Authority, is or will be required in connection with the execution and delivery
by Administrative Agent of the Operative Agreements to which it is party or the
performance by Administrative Agent of its obligations under such Operative
Agreements.

         (f) Brokers, etc. Administrative Agent has not engaged or authorized
any broker, finder, investment banker or other third party to act on its behalf,
directly or indirectly, as a broker, finder, investment banker, administrative
agent or in any other like capacity in connection with any of the Operative
Agreements or the transactions contemplated thereby. Administrative Agent shall
be responsible for, and shall indemnify, defend and hold each Lessor and Lessee
harmless from and against any and all claims, liabilities or demands by any
Person for broker's, finder's, investment banker's or administrative agent's
fees, commissions or other entitlements with respect to the Operative Agreements
and the transactions contemplated thereby (except to the extent arising from a
breach of Sections 5.1(cc) or 5.2(c)).

foreign jurisdiction, except where the failure to be so qualified would not have
a Material Adverse Effect.

statutes, regulations, franchises, and orders of, and all applicable
restrictions imposed by, any Authority, in respect of the conduct of its
business and the ownership of its properties (including, without limitation,
applicable statutes, rules, ordinances, regulations and orders relating to
Environmental Laws), except for such instances of non-compliance which would not
have, individually or in the aggregate, a Material Adverse Effect.

         (c) Punctual Payment. Lessee shall duly and punctually pay or cause to
be paid all Rent and all fees and other amounts from time to time owing
hereunder and under the other Operative Agreements, all in accordance with the

by Administrative Agent in connection with the establishment and perfection of
the security interest of Administrative Agent in the Collateral, to be recorded

                  (ii) As soon as practicable and, in any event, within 60 days

         detail, prepared in accordance with GAAP consistently applied, and
         certified by a senior vice president or the principal financial or
         principal accounting officer of Lessee, but subject, however, to normal
         year-end adjustments and the notes thereto.

         Certificate) signed on behalf of Lessee by a senior vice president.

         (h) Default and Acceleration of Material Debt. Lessee agrees that if an
Incipient Default or an Event of Default shall occur, or if an event or
condition shall occur that results in the acceleration of the maturity of
Indebtedness of Lessee in amounts exceeding twenty five million dollars
($25,000,000), or in the event that such acceleration should occur with respect
to Indebtedness of any Affiliates of Lessee, Lessee shall promptly notify
Administrative Agent thereof.

         (i) ERISA Events. Promptly upon Lessee's becoming aware of the
occurrence of any matter or matters referred to in the following clauses (i),
(ii) and (iii) involving liability that may reasonably be expected to exceed,
individually or in the aggregate, $25,000,000, Lessee shall notify
Administrative Agent and each of the Lessors in writing specifying the nature
thereof, what action Lessee is taking or proposes to take with respect thereto,
and, when known, any action taken by the Internal Revenue Service with respect
thereto: (i) a "Reportable Event" as such term is defined in Section 4043 of
ERISA, (ii) an "Accumulated Funding Deficiency" as such term is defined in
Section 302 of ERISA, or (iii) a "Prohibited Transaction", as such term is
defined in Section 4975 of the Code or described in Section 406 of ERISA, in
connection with any Pension Plan (or any trust created thereunder).

describe the nature of such Incipient Default or Event of Default and the action
Lessee is taking with respect thereto.

<PAGE>   23




         (l) Additional Information. Promptly upon receipt of a written request
from Administrative Agent or any Lessor, Lessee shall deliver to such requesting
party such other data and information as from time to time may be reasonably
requested.

         (m) Reports to Lessors. Lessee shall, concurrently with any notice,
delivery or other communication required to be delivered to Administrative Agent
pursuant to any Operative Agreement, deliver a copy of such notice, delivery or
other communication to each Lessor at such Lessor's current address.

         (n) Payment of Taxes. Lessee and its Subsidiaries shall promptly pay
and discharge all taxes, assessments and governmental charges or levies imposed
upon them or upon their income or profit or upon any property, real, personal or
mixed, belonging to them, provided that neither Lessee nor any Subsidiary shall
be required to pay any such tax, assessment, charge or levy if the same shall
not at the time be due and payable or can be paid thereafter without penalty or
if the validity thereof shall currently be contested in good faith by
appropriate proceedings diligently pursued and if Lessee or such Subsidiary, as
the case may be, shall have set aside on its books reserves deemed by it
adequate with respect to such tax, assessment, charge or levy. Nothing in this
Section shall be deemed to modify or restrict Lessee's obligations under Article
VIII hereof.

         Section 6.2 Negative Covenants of Lessee. Lessee covenants and agrees
with Lessors and Administrative Agent that during the Lease Term, and, if Lessee
has not purchased the Equipment pursuant to the Lease, for 90 days thereafter,
Lessee shall not and shall not permit any of its Subsidiaries to:

                  (a) Liens. Create, incur, assume or permit to exist any Liens
on the Equipment, except for Permitted Liens.

                  (b) Merger, Consolidation or Sale of Assets, Etc. Lessee will
not wind up, liquidate or dissolve its affairs, or effect any merger or
consolidation, and Lessee will not, and will not permit any consolidated
Subsidiary to, sell, lease or otherwise dispose of all or substantially all of
its property or assets (other than sales of inventory in the ordinary course of
business) except that this Section 6.2(b) shall not prohibit any of the
following transactions, or any agreement to effect the same:

                           (i) if, at the time thereof and immediately after
         giving effect thereto, no Event of Default or Default shall have
         occurred and be continuing, the merger of any other Person with and
         into Lessee or a Subsidiary, if, (A) in any transaction involving
         Lessee, Lessee is the surviving Person; (B) in any other transaction, a
         Wholly-Owned Subsidiary is the surviving entity and Lessee and its
         Subsidiaries shall be in compliance, on a pro forma basis after giving
         effect to such transaction, with the covenants contained in this
         Section 6.2 recomputed as of the last day of the most recently ended
         fiscal quarter of Lessee and its Subsidiaries as if such transaction
         had occurred on the first day of each relevant period for testing such
         compliance, and Lessee (with respect to any merger with a Person not a

                                      -18-

<PAGE>   24




         consolidated Subsidiary of Lessee) shall have delivered to the Agents
         an officer's certificate to such effect;

                           (ii) transactions and transfers of assets among or
         between Lessee and/or Wholly-Owned Subsidiaries or among and between
         Wholly-Owned Subsidiaries, in each case, not prohibited by Section
         6.2(f); and

                           (iii) dispositions not otherwise permitted hereunder
         which are made for fair market value; provided that (i) at the time of
         any disposition, no Default or Event of Default shall exist or shall
         result from such disposition, (ii) the aggregate sales price from such
         disposition shall be paid in cash or otherwise on payment terms
         satisfactory to Lessee or such Subsidiary, and (iii) the aggregate book
         value of all assets of Lessee and its Subsidiaries, taken as a whole,
         shall not be reduced at any time to an amount which is less than 80% of
         the aggregate book value of all assets of Lessee and its Subsidiaries,
         taken as a whole, on March 31, 1998, as reflected on Lessee's pro forma
         balance sheet dated March 31, 1998.

                  (c) ERISA. Permit any Plan maintained by it to (i) engage in
any "prohibited transaction" (as defined in Section 4975 of the Code) which
could reasonably be expected to result in material liability for excise taxes or
fiduciary liability under Section 406 of ERISA, (ii) incur any "accumulated
funding deficiency" (as defined in Section 302 of ERISA) whether or not waived,
or (iii) terminate any Plan in a manner that could result in the imposition of a
lien or encumbrance on the assets of Lessee or any of its Subsidiaries pursuant
to Section 4068 of ERISA.

                  (d) Public Utility Holding Company. Directly or indirectly
own, control or hold with power to vote any "voting security" of an "electric
utility company" or a "gas utility company" or of a "holding company" holding
any "voting security" of either the foregoing, as such terms are defined in the
Public Utility Holding Company Act of 1935.

                  (e) Transactions with Affiliates. Lessee will not, and will
not permit any consolidated Subsidiary to, directly or indirectly, conduct any
business or enter into, renew, extend or permit to exist any transaction
(including the purchase, sale, lease or exchange of any assets or the rendering
of any service) or series of related transactions with any Person who is not
either (i) Guarantor or one of Guarantor's consolidated Subsidiaries or (ii)
Weatherford\Al-Rushaid Limited or Weatherford Saudi Arabia Limited, on terms
that are less favorable to Lessee or such consolidated Subsidiary, as the case
may be, than would be available in a comparable arm's length transaction.
Notwithstanding the foregoing, the restrictions set forth in this covenant will
not apply to (i) the payment of reasonable and customary regular fees to
directors of the General Partner of the Lessee who are not employees of Lessee;
(ii) loans and advances to officers, directors and employees of Lessee and the
Subsidiaries for travel, entertainment and moving and other relocation expenses
made in direct furtherance and in the ordinary course of business of Lessee and
the Subsidiaries; (iii) any other transaction with any employee, officer or
director of Lessee or any of the Subsidiaries pursuant to employee benefit or
compensation arrangements entered into in the ordinary course of business and
approved by the General Partner of Lessee or the Board of Directors of such
Subsidiary

                                      -19-

permitted by this Agreement; and (iv) customary underwriting or similar
transactions with an investment banking Affiliate.

         Section 6.3 Covenants of Agents and Lessors. Administrative Agent and
Documentation Agent, each in its individual capacity, and each of the Lessors,
severally covenants and agrees with each of the other parties that: (a) it will
not directly or indirectly create, incur, assume or suffer to exist any Lessor
Liens arising by, through or under it on the Collateral, other than Permitted
Lessor Liens; (b) it will, at its own cost and expense, promptly take such
action in its individual capacity as may be necessary to discharge fully such
Lessor Liens created by it on the Collateral, other than Permitted Lessor Liens;
(c) it will not, except in compliance with the Operative Agreements, sell,
transfer or otherwise dispose of all or any part of the Equipment or the other
Collateral; and (d) it will not claim any depreciation with respect to the
Equipment during the term of the Lease.


                                   ARTICLE VII

                               General Indemnities

         Section 7.1 Indemnity. Whether or not the transactions contemplated
hereby are consummated, to the fullest extent permitted by applicable law,
Lessee waives and releases any claims now or hereafter existing against
Indemnitees on account of, and shall indemnify, reimburse and hold the
Indemnitees harmless on an after-tax basis from, any and all claims by third
parties (including, but not limited to, claims relating to trademark or patent
infringement and claims based upon negligence, strict liability in tort,
violation of laws, including, without limitation, Environmental Laws, statutes,
rules, codes or orders or claims arising out of any loss or damage to any
property or death or injury to any Person), any losses, damages or obligations
owing to third parties, any penalties, liabilities, demands, suits, judgments or
causes of action, and all legal proceedings (either administrative or judicial),
in each case whether or not the Indemnitee is a party thereto, and any costs or
expenses in connection therewith (including costs incurred in connection with
discovery) or in connection with the enforcement of this indemnity (including
reasonable attorneys' fees and expenses, and fees and expenses of internal
counsel, incurred by the Indemnitees), including, in each case, matters based on
or arising from the negligence of Indemnitees (subject to the proviso below),
which may be imposed on, incurred by or asserted against the Indemnitees in any
way relating to or arising in any manner out of:

         (a) the registration, purchase, manufacture, financing, refinancing,
acceptance, rejection, transfer of title, taking or foreclosure of a security
interest in, ownership, delivery, condition, lease, sublease, assignment,
storage, transportation, possession, use, operation, return or other disposition
of any of the Equipment, or any defect in any such Equipment, arising from the
material or any article used therein or from the design, testing or use thereof,
or from any maintenance, service, repair, modification, overhaul or testing of
any such Equipment regardless of when such defect shall be discovered, whether
or not such Equipment is in the possession of Lessee and no matter where it is
located; or

                                      -20-

<PAGE>   26




         (b) this Participation Agreement, any other Operative Agreement or any
document or certificate delivered in connection therewith, the enforcement
hereof or thereof or the consummation of the transactions contemplated hereby or
thereby;

provided that Lessee shall not be obligated to indemnify an Indemnitee for any
such claim, loss, damage, liability, obligation, penalty, demand or suit to the
extent the same results directly from:

                  (i) the willful misconduct or gross negligence of such
         Indemnitee; (provided that the failure of the Administrative Agent to
         prominently display its Texas sales tax permit in its Houston, Texas
         office shall not constitute willful misconduct or gross negligence for
         this purpose);

                  (ii) the creation or existence of a Lessor Lien attributable
         to such Indemnitee;

                  (iii) any claim or liability to the extent it arises solely
         out of events occurring after Lessee's discharge of all its obligations
         under the Lease; or

                  (iv) any Impositions described in Section 8.1 except any
         amount necessary under this Section 7.1 to hold the Indemnitee harmless
         (subject to Section 8.3) from all Impositions required to be paid by
         such Indemnitee with respect to the receipt or accrual of such
         indemnity under the laws of any Authority in the United States;

provided, however, that nothing in the preceding proviso shall be deemed to
exclude or limit any claim that any Indemnitee may have under any Operative
Agreement or applicable laws from Lessee for breach of its representations,
warranties or covenants.

         Section 7.2 Excessive Use Indemnity. In the event that at the end of
the Lease Term: (a) Lessee elects the Sale Option; and (b) after paying to
Administrative Agent any amounts due under Section 11.3 of the Lease,
Administrative Agent does not have sufficient funds to reduce the Lease Balance
to zero, then Lessee shall promptly pay over to Administrative Agent the
shortfall unless Lessee delivers a report from the Appraiser in form and
substance satisfactory to the Required Lessors which establishes that the
decline in value in each item of Equipment which was sold pursuant to the Sale
Option from that amount anticipated for such date in the Appraiser's report
delivered with respect to such Equipment on the applicable Delivery Date was not
due to extraordinary use, failure to maintain or replace, failure to use,
workmanship or method of installation or removal or any other cause or condition
within the power of Lessee to control or effect (each an "Excessive Use").

         Section 7.3 Increased Capital Costs. If any change in, or the adoption,
effectiveness, interpretation, reinterpretation or phase-in of, any law or
regulation, directive, guideline, decision or request (whether or not having the
force of law) of any court, central bank regulator or other Authority ("Change
in Law") affects or would affect the amount of capital required or expected to

                                      -21-

<PAGE>   27




be maintained by any Lessor directly or by its parent company (including,
without limitation, any reserve requirements specified under regulations issued
from time to time by the Board of Governors of the Federal Reserve System and
then applicable to assets or liabilities consisting of and including
"Eurocurrency Liabilities" as defined in Regulation D of such Board of
Governors) on account of the execution, delivery and performance hereof or of
the Lease or the transactions contemplated in the Operative Agreements, and such
Lessor determines (in its sole and absolute discretion) that the rate of return
on it or its parent's capital as a consequence of the Funding made by such
Lessor hereunder to pay its share of the Purchase Price plus Capitalized
Transaction Costs is reduced to a level below that which such Lessor or its
parent could have achieved but for the occurrence of any such circumstances,
then, in any such case, upon written notification from time to time by Lessor to
Lessee, Lessee shall, within five (5) Business Days following receipt of the
statement referred to in the next sentence, pay directly to such Lessor
additional amounts sufficient to compensate Lessor or its parent for such
reduction in rate of return (subject to Section 8.3). A statement of a Lessor as
to any such additional amount or amounts (including calculations thereof in
reasonable detail) shall, in the absence of manifest error, be presumed correct.
In determining such amount, each Lessor shall use any method of averaging or
attribution that it (in its reasonable discretion) shall deem applicable.
 Lessee shall have the right, if it receives from any Lessor any notice referred
to in this Section 7.3, upon three (3) Business Days notice to Administrative
Agent (which shall notify each Lessor), to convert the Interest Rate from the
LIBO Rate to the Alternate Base Rate at the end of the then current Rent Period.
Each Lessor will notify Lessee through the Administrative Agent of any event
occurring after the date of this Agreement which would entitle such Lessor to
compensation pursuant to this section as promptly as practicable after it
obtains knowledge thereof and determines to request such compensation.

         Section 7.4 LIBO Rate Unlawful. If any Lessor shall determine in good
faith (which determination shall, upon notice thereof to Lessee, be conclusive
and binding on Lessee) that a Change in Law makes it unlawful, or the central
bank or other Authority asserts that it is unlawful, for such Lessor to make,
continue or maintain any amount of such Lessor's Funding on a LIBO Rate basis,
the obligations of such Lessor to make, continue or maintain any such Funding
shall, upon such determination, forthwith be suspended until such Lessor shall
notify Lessee that the circumstances causing such suspension no longer exist,
and all Variable Rent allocable to such Lessor, commencing with the Rent Period
in which such notice is given, shall automatically be determined on an Alternate
Base Rate plus the Applicable Margin basis beginning on the next immediately
succeeding Payment Date with respect thereto or sooner, if required by such law
or assertion.

         Section 7.5 Funding Losses. Lessee agrees to reimburse each Lessor for
any loss or expense incurred (including any loss or expense incurred by reason
of the liquidation or reemployment of deposits or other funds acquired by such
Lessor to make, continue or maintain any portion of its Outstanding Investment
as a LIBO Rate financing) as a result of (i) the failure of any Delivery Date
Closing to occur on the Delivery Date specified in the applicable Delivery Date
Notice, (ii) any payment of all or any portion of the Lease Balance for any
reason on a date other than a Payment Date or (iii) any transfer pursuant to
Section 7.6 on a date other than a Payment Date. Each Lessor

                                      -22-

<PAGE>   28




shall promptly notify Lessee in writing of the amount of any claim under this
Section 7.5, the reason or reasons therefor and the additional amount required
fully to compensate such Lessor for such loss or expense. Such written notice
(which shall include calculations in reasonable detail) shall, in the absence of
manifest error, be presumed correct.

         Section 7.6 Actions of Affected Lessors. Each Lessor shall use
reasonable efforts (including reasonable efforts to change the booking office
for this transaction) to avoid or minimize any amounts which might otherwise be
payable pursuant to Section 7.3; provided, however, that such efforts shall not
be deemed by such Lessor, in its sole discretion, to be disadvantageous to it.
In the event that such reasonable efforts are insufficient to avoid or minimize
such amounts that might be payable pursuant to Section 7.3, then such Lessor
(the "Affected Lessor") shall use its reasonable efforts to transfer to any
other Lessor approved by Lessee (which itself is not then an Affected Lessor)
its rights and obligations hereunder; provided, however, that such transfer
shall not be deemed by such Affected Lessor, in its sole discretion, to be
disadvantageous to it (other than the economic disadvantage of ceasing to be a
Lessor). In the event that the Affected Lessor is unable, or otherwise is
unwilling, so to transfer its rights and obligations, Lessee may designate an
alternate financial institution to purchase the Affected Lessor's rights and
obligations hereunder, at the amount of such Lessor's Outstanding Investment
plus accrued Variable Rent, indemnities, and other amounts owing to such Lessor
and, subject to the provisions of Sections 7.5 and 11.8, the Affected Lessor
shall transfer its rights and obligations to such alternate financial
institution and such alternate financial institution shall become a Lessor
hereunder.


                                  ARTICLE VIII

                              General Tax Indemnity

         Section 8.1 General Tax Indemnity. Lessee agrees to pay or reimburse
Indemnitees for, and to indemnify and hold Indemnitees harmless on an after tax
basis from, all Impositions arising at, or relating to, any time prior to or
during the Interim Period or the Base Period or any Renewal Term, if any, or
upon any termination of the Lease or prior to, or upon the return of, the
Equipment to Administrative Agent, and levied or imposed upon Indemnitees or the
Equipment or other Collateral directly or otherwise, by any Federal, state,
provincial or local government or taxing authority in the United States or by
any foreign country or foreign or international taxing authority upon or with
respect to: (a) the Equipment or any other Collateral; (b) the exportation,
importation, manufacture, financing, refinancing, registration, purchase,
ownership, delivery, condition, lease, sublease, assignment, storage,
transportation, possession, use, operation, maintenance, repair, return, sale
(including to Administrative Agent or any Lessee pursuant to the Operative
Agreements), transfer of title or other disposition thereof; (c) the rentals,
receipts, or earnings arising from any of the Equipment; or (d) the Lease, this
Participation Agreement or any payment made thereunder; provided that this
Section 8.1 shall not apply to: (i) Impositions which are based upon or measured
by the Indemnitee's net income, except any such Imposition imposed upon the
Indemnitee by a state or foreign government or taxing authority by reason of the
presence of Equipment or any other

                                      -23-

<PAGE>   29




Collateral therein; (ii) Impositions characterized under local law as franchise,
net worth, or shareholder's capital (excluding, however, any value added,
license, property or similar Impositions and any such Imposition imposed upon an
Indemnitee by a State or foreign government or taxing authority by reason of the
presence of Equipment or any other Collateral therein); and (iii) Impositions
based upon the voluntary transfer, assignment or disposition by Administrative
Agent or any Lessor of any interest in any of the Equipment (other than any
deemed transfer of any interest in any of the Equipment as a result of the
syndication of the transaction contemplated hereby, a transfer of any interest
in any of the Equipment pursuant to the exercise of remedies under the Operative
Agreements, transfers of any interest in any of the Equipment pursuant to the
exercise of the Lessee Purchase Option or Sale Option, a transfer of any
interest in any of the Equipment to Lessee or otherwise pursuant to the Lease);
and (iv) Impositions resulting from the gross negligence, willful misconduct or
fraud of such Indemnitee (provided that the failure of the Administrative Agent
to prominently display its Texas sales tax permit in its Houston, Texas office
shall not constitute willful misconduct or gross negligence for this purpose).
Notwithstanding the foregoing provisions of this Section 8.1, Lessee shall pay
or reimburse, and indemnify and hold harmless, any Lessor which has complied
with Section 8.5, from any deduction or withholding of any United States Federal
income or other tax.

         Section 8.2 Contest. Lessee shall pay on or before the time or times
prescribed by law any Impositions (except any Impositions excluded by Section
8.1); provided, however, that Lessee shall be under no obligation to pay any
such Imposition so long as the payment of such Imposition is not delinquent or
is being contested by a Permitted Contest. If any claim or claims is or are made
against any Indemnitee for any Imposition which is subject to indemnification as
provided in Section 8.1, such Indemnitee shall as soon as practicable notify
Lessee and if, in the reasonable opinion of tax counsel acceptable to the
Indemnitee there exists a reasonable basis to contest such Imposition and if the
provisos of the definition of "Permitted Contest" continue to be satisfied and
so long as no Event of Default exists and no income tax or unindemnified claim
is also involved, and the Lessee admits in writing its duty to indemnify for
such claim, Lessee at its expense may, to the extent permitted by applicable law
to pursue such claim in its own name, contest such imposition, and subsequently
may appeal any adverse determination, in the appropriate administrative and
legal forums. If the above described conditions are satisfied but the claim
involves income tax or an unindemnified claim or must be pursued in the name of
the Indemnitee, and the amount at issue exceeds $25,000, then upon the request
of Lessee to such Indemnitee, the Indemnitee, at Lessee's expense, shall contest
any such Imposition through applicable administrative forums. Lessee shall pay
all expenses incurred by the Indemnitee in contesting any such Imposition
including, without limitation, all reasonable attorneys' and accountants' fees,
including the allocated costs of internal counsel, upon demand by the
Indemnitee. Lessee shall have the right to consult with respect to the conduct
of any proceedings controlled by the Indemnitee and Indemnitee shall consider
such consultations in good faith; provided, however, that such consultation
shall not interfere with the Indemnitee's control of such contest. Lessee shall
in all events be kept informed, to the extent practicable, of material
developments relative to such proceedings. The Indemnitee shall have the right
to participate in the conduct of any proceedings controlled by Lessee and the
Indemnitee shall in all events be kept informed, to the extent practicable, of
material developments relative to such

                                      -24-

<PAGE>   30




proceedings. The Indemnitees agree that a contested claim for which Lessee would
be required to make a reimbursement payment hereunder will not be settled or
compromised without Lessee's prior written consent (which consent shall neither
be unreasonably delayed nor withheld other than in good faith), unless the
provisos of the definition of "Permitted Contest" would not continue to be
satisfied, an Event of Default occurs or the Indemnitee waives its right to
indemnification with respect thereto. The failure of an Indemnitee to timely
contest a claim against it for any Imposition which is subject to
indemnification under Section 8.1 and for which it has an obligation to Lessee
to contest under this Section 8.2 in the manner required by applicable law or
regulations where Lessee has timely requested that such Indemnitee contest such
claim shall relieve Lessee of its obligations to such Indemnitee under Section
8.1 with respect to such claim only to the extent such failure precludes
contest. If applicable law requires the payment of a contested Imposition as a
condition to, or regardless of, its being contested, and Lessee chooses to
contest such Imposition or to direct the Indemnitee to contest such Imposition
in accordance with this Section, then Lessee shall provide the Indemnitee with
the funds to pay such Imposition, such provision of funds to be deemed a
non-interest bearing loan by Lessee to the Indemnitee to be repaid by any
recovery of such Imposition from such contest and any remaining unpaid amount
not recovered to offset Lessee's obligation to indemnify the Indemnitee for such
Imposition. In the event that the Indemnitee receives a refund (or like
adjustment) in respect of any Imposition for which the Indemnitee has been
reimbursed by Lessee, the Indemnitee shall immediately remit the amount of such
refund (or like adjustment) to Lessee, net of all costs and expenses incurred by
such Indemnitee.

         Section 8.3 Gross Up. If an Indemnitee shall not be entitled to an
immediate corresponding and equal deduction with respect to any payment or
Imposition which Lessee is required to pay or reimburse under Article VII,
Section 8.1 or Section 8.2 (each such payment or reimbursement under Article
VII, Section 8.1 or Section 8.2, an "original payment") and which original
payment constitutes income to such Indemnitee, then Lessee shall pay to such
Indemnitee on demand the amount of such original payment on a gross-up basis
such that, after subtracting all Impositions imposed on such Indemnitee with
respect to such original payment by Lessee (including any Impositions otherwise
excluded by Section 8.1 and assuming for this purpose that such Indemnitee was
subject to taxation at the maximum marginal Federal, state and local tax rates
applicable to such Indemnitee for the year in which such income is taxable),
such payments shall be equal to the original payment to be received (net of any
credits, deductions or other tax benefits then actually recognized that arise
from the payment by such Indemnitee of any amount, including taxes, for which
the payment to be received is made).

         Section 8.4 Tax Returns. Except as otherwise provided in the third
sentence below, Lessee shall prepare and file (whether or not it is a legal
obligation of an Indemnitee) all tax returns or reports that may be required
with respect to any Impositions assessed, charged or imposed on the Equipment or
the Lease, including, but not limited to sales and use taxes, property taxes (ad
valorem and real property) and any other tax or charge based upon the ownership,
leasing, subleasing, rental, sale, purchase, possession, use, operation,
delivery, return or other disposition of any of the Equipment or upon the
rentals or the receipts therefrom (excluding, however, any tax based upon the
net income of an Indemnitee). Lessee may notify in writing all applicable
Authorities having

                                      -25-

<PAGE>   31




jurisdiction with respect to personal property taxes that Lessee is the
appropriate party for receiving notices of (or copies of, if such Authority is
required by law to notify Administrative Agent) assessment, appeal and payment
with respect to the Equipment. If an Indemnitee is obligated by law to file any
such reports or returns, then Lessee shall at least 20 days before the same are
due, prepare the same and forward them to the Indemnitee, as appropriate, with
detailed instructions as to how to comply with all applicable filing
requirements, together with funds in the amount of any payment required pursuant
thereto. Indemnitee shall forward to Lessee at its address listed in Section
11.4 copies of all assessment and valuation notices it receives as soon as
practicable; provided that Indemnitee's failure to deliver such notices on a
timely basis shall not relieve Lessee of any obligations hereunder. The
Participants agree that neither they nor any corporation controlled by them, or
under common control with them, directly or indirectly will at any time take any
action or with respect to the filing of any income tax return, including an
amended income tax return, inconsistent with the intention of the parties
expressed in Section 4.1(b) and (d) hereof.

         Section 8.5 Withholding Tax Exemption. Upon the execution of this
Agreement, each Lessor that is not incorporated under the laws of the United
States or a State thereof shall, and with respect to any date on which any
Indemnitee transfers any right, title or interest in the Equipment to a
transferee that is not incorporated under the laws of the United States or a
State thereof, such transferee shall deliver, at least five (5) Business Days
prior to any such transfer, to Lessee and Administrative Agent two duly
completed copies of United States Internal Revenue Service Form 1001 or 4224,
certifying in either case that such Lessor is entitled to receive payments under
this Agreement and the other Operative Agreements without deduction or
withholding of any United States Federal income taxes. Each Lessor which so
delivers a Form 1001 or 4224 further undertakes to deliver to Lessee and
Administrative Agent two additional copies of such form (or a successor form) on
or before the date that such form expires or becomes obsolete or after the
occurrence of any event requiring a change in the most recent forms so delivered
by it, and such amendments thereto or extensions or renewals thereof as may be
reasonably requested by Lessee or Administrative Agent, in each case certifying
that such Lessor is entitled to receive payments under this Agreement and the
other Operative Agreements without deduction or withholding of any United States
Federal income taxes, unless prior to the date on which any such delivery would
otherwise be required any change in treaty, law or regulation or in the
interpretation thereof by the applicable taxing Authority occurring after such
Lessor became a Lessor hereunder has rendered all such forms inapplicable and no
successor forms having substantially the same effect as Forms 1001 and 4224 have
been adopted by the IRS, and such Lessor advises Lessee and Administrative Agent
in writing that, as a result of such change in treaty, law or regulation or
interpretation, it is not capable of receiving payments without any withholding
of United States Federal income tax. In the event that any Indemnitee ceases to
be exempt from withholding of any United States Federal income taxes due to a
change in treaty, law, regulation or in the interpretation thereof by the
applicable taxing Authority, such Indemnitee shall, at the request of Lessee, if
such additional amounts can be reduced or eliminated, by transferring the
Equipment or any other Collateral to any branch or lending office of such
Indemnitee without incurring any adverse regulatory consequences or cost for
which Lessee is not willing on or prior to the transfer to indemnify such
Indemnitee and which does not adversely interfere with the business of such
branch or lending office, effect such transfer.

                                   ARTICLE IX

                              Administrative Agent

         Section 9.1 Appointment of Administrative Agent; Powers and
Authorization to Take Certain Actions.

         (a) Each Lessor irrevocably appoints and authorizes ABN AMRO Bank N.V.
to act as its administrative agent hereunder, with such powers as are
specifically delegated to Administrative Agent by the terms hereof, together
with such other powers as are reasonably incidental thereto. Each Lessor
authorizes and directs Administrative Agent to, and Administrative Agent agrees
for the benefit of the Lessors that it will, on the Documentation Date, the
Initial Delivery Date and each other Delivery Date, accept the documents
described in Article III of this Participation Agreement. Administrative Agent
accepts the agency hereby created applicable to it and agrees to receive all
payments and proceeds pursuant to the Operative Agreements and disburse such
payments or proceeds in accordance with the Operative Agreements. Administrative
Agent shall have no duties or responsibilities except those expressly set forth
in the Lease and this Participation Agreement. Administrative Agent shall not be
responsible to any Lessor (or to any other Person) (i) for any recitals,
statements, representations or warranties of any party contained in the Lease,
this Participation Agreement, or in any certificate or other document referred
to or provided for in, or received by any of them under, the Operative
Agreements, other than the representations and warranties made by Administrative
Agent in Section 5.3, or (ii) for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of the Collateral or the title
thereto (subject to Administrative Agent's obligations under Section 6.3) or of
the Lease or any other document referred to or provided for therein or (iii) for
any failure by Lessee, any Lessor or any other third party (other than
Administrative Agent) to perform any of its obligations under any Operative
Agreement. Administrative Agent may employ agents, trustees or
attorneys-in-fact, may vest any of them with any property, title, right or power
deemed necessary for the purposes of such appointment and shall not be
responsible for the negligence or misconduct of any of them selected by it.
Neither Administrative Agent nor any of its directors, officers, employees or
agents shall be liable or responsible for any action taken or omitted to be
taken by it or them hereunder, or in connection herewith, except for its or
their own gross negligence or willful misconduct.

         (b) Administrative Agent shall not have any duty or obligation to
manage, control, use, operate, store, lease, sell, dispose of or otherwise deal
with any Equipment, any other Collateral or the Lease, or to otherwise take or
refrain from taking any action under, or in connection with, this Agreement, the
Lease or any related document to which Administrative Agent is a party, except
as expressly provided by the terms hereof, and no implied duties of any kind
shall be read into any Operative Agreement against Administrative Agent. The
permissive right of Administrative Agent to take actions enumerated in this
Agreement and the Lease shall never be construed as a duty, unless
Administrative Agent is instructed or directed to exercise, perform or enforce
one or more rights by the Required Lessors (provided that Administrative Agent
has received indemnification reasonably

                                      -27-

<PAGE>   33




satisfactory to it). No provision of the Operative Agreements shall require
Administrative Agent to expend or risk its own funds or otherwise incur any
financial liability in the performance of any of its obligations under the
Operative Agreements, or in the exercise of any of its rights or powers
thereunder. It is understood and agreed that the duties of Administrative Agent
are ministerial in nature.

         (c) Except as specifically provided herein, Administrative Agent is
acting hereunder solely as administrative agent and is not responsible to any
party hereto in its individual capacity, except with respect to any claim
arising from Administrative Agent's gross negligence or willful misconduct
(provided that the failure of the Administrative Agent to prominently display
its Texas sales tax permit in its Houston, Texas office shall not constitute
willful misconduct or gross negligence for this purpose) or any breach of a
representation or covenant made in its individual capacity.

         (d) Administrative Agent may accept deposits from, lend money to and
otherwise deal with Lessee or any of its Affiliates with the same rights as it
would have if it were not the named Administrative Agent hereunder.

         Section 9.2 Reliance. Administrative Agent may rely upon, and shall not
be bound or obligated to make any investigation into the facts or matters stated
in, any certificate, notice or other communication (including any communication
by telephone, telecopy, telex, telegram, e-mail or cable) reasonably believed by
it to be genuine and correct and to have been made, signed or sent by or on
behalf of the proper Person or Persons, and upon advice and statements of legal
counsel, independent accountants and other experts selected by Administrative
Agent (including any expert selected by Administrative Agent to aid
Administrative Agent in any calculations required in connection with its duties
under the Operative Agreements).

         Section 9.3 Action Upon Instructions Generally. Subject to Sections 9.4
and 9.6, upon written instructions of the Required Lessors, Administrative Agent
shall, on behalf of the Lessors, give such notice or direction, exercise such
right, remedy or power hereunder or in respect of any Equipment, and give such
consent or enter into such amendment to any document to which it is a party as
Administrative Agent as may be specified in such instructions. Administrative
Agent shall deliver to each Lessor a copy of each notice, report and certificate
received by Administrative Agent pursuant to the Operative Agreements.
Administrative Agent shall have no obligation to investigate or determine
whether there has been an Event of Default or an Incipient Default.
Administrative Agent shall not be deemed to have notice or knowledge of an Event
of Default or Incipient Default unless a Responsible Officer of Administrative
Agent is notified in writing of such Event of Default or Incipient Default. If
Administrative Agent receives notice of an Event of Default, Administrative
Agent shall give prompt notice thereof, at Lessee's expense, to each Lessor.
Subject to Sections 9.4 and 9.6 and Article X, Administrative Agent shall take
action or refrain from taking action with respect to such Event of Default as
directed by the Required Lessors; provided that, unless and until Administrative
Agent receives such directions, Administrative Agent may refrain from taking any
action, or may act in its discretion, with respect to such Event of Default.
Prior to the date the Lease

                                      -28-

<PAGE>   34




Balance shall have become due and payable by acceleration pursuant to Section
8.2 of the Lease, Required Lessors may deliver written instructions to
Administrative Agent to waive, and Administrative Agent shall waive pursuant
thereto, any Event of Default and its consequences; provided that in the absence
of written instructions from all Lessors, Administrative Agent shall not waive
any (i) Payment Default or (ii) covenant or provision which, under Section 10.1,
cannot be modified or amended without the consent of all Lessors. As to any
matters not expressly provided for by this Agreement, Administrative Agent shall
in all cases be fully protected in acting, or in refraining from acting,
hereunder in accordance with instructions signed by the Required Lessors and
such instructions of the Required Lessors and any action taken or failure to act
pursuant thereto shall be binding on each Lessor.

         Section 9.4 Indemnification. Each Lessor shall reimburse and hold
Administrative Agent harmless, ratably in accordance with its Outstanding
Investment at the time the indemnification is required to be given (but only to
the extent that any such indemnified amounts have not in fact been paid to
Administrative Agent by, or on behalf of, Lessee in accordance with Section
7.1), from any and all claims, losses, damages, obligations, penalties,
liabilities, demands, suits, judgments, or causes of action, and all legal
proceedings, and any reasonable costs or expenses in connection therewith,
including allocated charges, costs and expenses of internal counsel of
Administrative Agent and all other reasonable attorneys' fees and expenses
incurred by Administrative Agent, in any way relating to or arising in any
manner out of (i) any Operative Agreement, the enforcement hereof or thereof or
the consummation of the transactions contemplated thereby, or (ii) instructions
from the Required Lessors (including, without limitation, the costs and expenses
that Lessee is obligated to and does not pay hereunder), provided that no Lessor
shall be liable for any of the foregoing to the extent they arise from (a) the
gross negligence or willful misconduct of Administrative Agent (provided that
the failure of the Administrative Agent to prominently display its Texas sales
tax permit in its Houston, Texas office shall not constitute willful misconduct
or gross negligence for this purpose), (b) the inaccuracy of any representation
or warranty or breach of any covenant given by Administrative Agent in Section
5.3 or Section 6.3 hereof or in the Lease, (c) in the case of Administrative
Agent's handling of funds, the failure to act with the same care as
Administrative Agent uses in handling its own funds or (d) any taxes, fees or
other charges payable by Administrative Agent based on or measured by any fees,
commissions or compensation received by it for acting as Administrative Agent in
connection with the transactions contemplated by the Operative Agreements.

         Section 9.5 Independent Credit Investigation. Each Lessor by entering
into this Agreement agrees that it has, independently and without reliance on
Administrative Agent or any other Lessor and based on such documents and
information as it has deemed appropriate, made its own credit analysis of Lessee
and its own decision to enter into this Agreement and each of the other
Operative Agreements to which it is a party and that it will, independently and
without reliance upon Administrative Agent or any other Lessor, and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own analysis and decisions in taking action under this
Agreement and any related documents to which it is a party. Administrative Agent
shall not be required to keep itself informed as to the performance or
observance by Lessee of any other

                                      -29-

<PAGE>   35




document referred to (directly or indirectly) or provided for herein or to
inspect the properties or books of Lessee. Except for notices or statements
which Administrative Agent is expressly required to give under this Agreement
and for notices, reports and other documents and information expressly required
to be furnished to Administrative Agent alone (and not also to each Lessor, it
being understood that Administrative Agent shall forward copies of same to each
Lessor) hereunder or under any other Operative Agreement, Administrative Agent
shall not have any duty or responsibility to provide any Lessor with copies of
notices or with any credit or other information concerning the affairs,
financial condition or business of Lessee (or any of its affiliates) that may
come into the possession of Administrative Agent or any of its Affiliates.

         Section 9.6 Refusal to Act. Except for notices and actions expressly
required of Administrative Agent hereunder and except for the performance of its
covenants in Section 6.3, Administrative Agent shall in all cases be fully
justified in failing or refusing to act unless (a) it is indemnified to its
reasonable satisfaction by the Lessors against any and all liability and
reasonable expense which may be incurred by it by reason of taking or continuing
to take any such action (provided that such indemnity shall not be required to
extend to liability or expense arising from any matter described in clauses (a)
through (d) of Section 9.4, it being understood that no action taken by
Administrative Agent in accordance with the instructions of the Required Lessors
shall be deemed to constitute any such matter) and (b) it is reasonably
satisfied that such action is not contrary to any Operative Agreement or to any
applicable law.

         Section 9.7 Resignation of Administrative Agent; Appointment of
Successor. Subject to the appointment and acceptance of a successor
Administrative Agent as provided below, Administrative Agent may resign at any
time by giving notice thereof to each Lessor and Lessee. Upon any such
resignation, the Required Lessors at the time of the resignation shall have the
right (with the reasonable, prompt approval of Lessee unless an Event of Default
shall be continuing) to appoint a successor Administrative Agent which shall be
a financial institution having a combined capital and surplus of not less than
$100,000,000. If, within 30 calendar days after the retiring Administrative
Agent's giving of notice of resignation, a successor Administrative Agent is not
so appointed and does not accept such appointment, then the retiring
Administrative Agent may appoint a successor Administrative Agent and transfer
to such successor Administrative Agent all rights and obligations of the
retiring Administrative Agent. Such successor Administrative Agent shall be a
financial institution having combined capital and surplus of not less than
$100,000,000. Upon the acceptance of any appointment as Administrative Agent
hereunder by a successor Administrative Agent, such successor Administrative
Agent shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Administrative Agent and the retiring
Administrative Agent shall be discharged from duties and obligations as
Administrative Agent thereafter arising hereunder and under any related
document. If the retiring Administrative Agent does not appoint a successor, any
Lessor shall be entitled to apply to a court of competent jurisdiction for such
appointment, and such court may thereupon appoint a successor to act until such
time, if any, as a successor shall have been appointed as above provided.


                                      -30-

<PAGE>   36




         Section 9.8 Separate Administrative Agent. The Required Lessors may,
and if they fail to do so at any time when they are so required, Administrative
Agent may, for the purpose of meeting any legal requirements of any jurisdiction
in which any Equipment or Collateral may be located, appoint one or more
individuals or corporations either to act as co-agent jointly with
Administrative Agent or to act as separate administrative agent of all or any
part of the Equipment or Collateral or the Lease, and vest in such individuals
or corporations, in such capacity, such title to the Equipment or Collateral or
the Lease or any part thereof, and such rights or duties as Administrative Agent
may consider necessary or desirable. Administrative Agent shall not be required
to qualify to do business in any jurisdiction where it is not now so qualified.
Administrative Agent shall execute, acknowledge and deliver all such instruments
as may be required by any such co-agent or separate administrative agent more
fully confirming such title, rights or duties to such co-agent or separate
administrative agent. Upon the acceptance in writing of such appointment by any
such co-agent or separate administrative agent, it, she or he shall be vested
with such interest in the Equipment or Collateral and the Lease or any part
thereof, and with such rights and duties, not inconsistent with the provisions
of the Operative Agreements, as shall be specified in the instrument of
appointment, jointly with Administrative Agent (except insofar as local law
makes it necessary for any such co-agent or separate administrative agent to act
alone), subject to all terms of the Operative Agreements. Any co-agent or
separate administrative agent, to the fullest extent permitted by legal
requirements of the relevant jurisdiction, at any time, by an instrument in
writing, shall constitute Administrative Agent its attorney-in-fact and
administrative agent, with full power and authority to do all acts and things
and to exercise all discretion on its behalf and in its name. If any co-agent or
separate administrative agent shall die, become incapable of acting, resign or
be removed, the interest in the Equipment or Collateral and the Lease and all
rights and duties of such co-agent or separate administrative agent shall, so
far as permitted by law, vest in and be exercised by Administrative Agent,
without the appointment of a successor to such co-agent or separate
administrative agent.

         Section 9.9 Termination of Agency. The agency created hereby shall
terminate upon the final disposition by Administrative Agent of all Collateral
at any time subject hereto and the final distribution by Administrative Agent of
all moneys or other property or proceeds received pursuant to the Lease in
accordance with its terms, provided that at such time Lessee shall have complied
fully with all the terms hereof.

         Section 9.10 Compensation of Agency. As compensation for the
performance of Administrative Agent's obligations hereunder, Lessee shall pay to
Administrative Agent, on the Initial Delivery Date and on each anniversary of
the Initial Delivery Date occurring during the Lease Term, a fee (the "Agency
Fee") in the amount referred to in the Fee Letter Agreement.

         Section 9.11 Limitations. It is expressly understood and agreed by and
among the parties hereto that, except as otherwise provided herein or in the
other Operative Agreements: (a) this Participation Agreement and the other
Operative Agreements to which Administrative Agent is a party are executed by
Administrative Agent, not in its individual capacity (except with respect to the
representations and covenants of Administrative Agent in Sections 5.3 and 6.3),
but solely as Administrative Agent under the Operative Agreements in the
exercise of the power and authority

                                      -31-

<PAGE>   37




conferred and vested in it as such Administrative Agent; (b) each and all of the
undertakings and agreements herein made on the part of Administrative Agent are
each and every one of them made and intended not as personal undertakings and
agreements by Administrative Agent, or for the purpose or with the intention of
binding Administrative Agent personally, but are made and intended for the
purpose of binding only the Collateral unless expressly provided otherwise; (c)
actions to be taken by Administrative Agent pursuant to its obligations under
the Operative Agreements may, in certain circumstances, be taken by
Administrative Agent only upon specific authority of the Lessors; (d) nothing
contained in the Operative Agreements shall be construed as creating any
liability on Administrative Agent, individually or personally, or any
incorporator or any past, present or future subscriber to the capital stock of,
or stockholder, officer or director, employee or agent of, Administrative Agent
to perform any covenants either express or implied contained herein, all such
liability, if any, being expressly waived by the other parties hereto and by any
Person claiming by, through or under them; and (e) so far as Administrative
Agent, individually or personally, is concerned, the other parties hereto and
any Person claiming by, through or under them shall look solely to the
Collateral and Lessee for the performance of any obligation under any of the
instruments referred to herein; provided, however, that nothing in this Section
9.11 shall be construed to limit in scope or substance the general corporate
liability of Administrative Agent in respect of its gross negligence or willful
misconduct (provided that the failure of the Administrative Agent to prominently
display its Texas sales tax permit in its Houston, Texas office shall not
constitute willful misconduct or gross negligence for this purpose) or those
representations, warranties and covenants of Administrative Agent in its
individual capacity set forth herein or in any of the other agreements
contemplated hereby.


                                    ARTICLE X

                       Amendments to Operative Agreements

         Section 10.1 Amendments to Operative Agreements With Consent of
Lessors. This Participation Agreement and each of the other Operative Agreements
shall be changed, waived, discharged or terminated with respect to Lessee and
each Lessor upon the ratification in writing of such change, waiver, discharge
or termination by Lessee, Guarantor (as to the Guaranty only) and the Required
Lessors, in which case such change, waiver, discharge or termination shall be
effective as to each Lessor, Guarantor and Lessee; provided no such change,
waiver, discharge or termination shall, without the written ratification of each
Lessor:

                  (i) modify any of the provisions of this Section 10.1 or

         part thereof except as contemplated in the Operative Agreements, or
         deprive any Lessor of the benefit of the security interest in the

Administrative Agent. Without the prior written consent of Administrative Agent,
no amendment of, supplement to, or waiver or modification of, any Operative
Agreement shall adversely affect Administrative Agent's rights or immunities or

proposed by Lessee or Guarantor) withholding of, any future amendments,
supplements, waivers or consents with respect to the Operative Agreements
(including without limitation any legal services rendered in connection with or
arising under Section 6.1 hereof), it being understood that Lessee shall only be
required to pay for one firm of legal counsel to Administrative Agent and
Lessors in respect of any transaction under this clause (a); (b) any Casualty or

and documentation of any restructuring or "workout," whether or not consummated,
of any Operative Agreement; (d) the enforcement of the rights or remedies under
the Operative Agreements; (e) further assurances requested pursuant to Section

Option described in Section 11.3 of the Lease; (g) any transfer by
Administrative Agent or a Lessor of any interest in the Operative Agreements
during the continuance of an Event of Default; and (h) the fees referred to
herein.

         Section 11.6 Counterparts. This Participation Agreement may be executed
in any number of counterparts and by different parties hereto on separate
counterparts, each executed counterpart constituting an original but all
together one agreement.

         Section 11.7 Severability. Whenever possible, each provision of this
Participation Agreement shall be interpreted in such manner as to be effective
and valid under applicable law; but if any provision of this Participation
Agreement shall be prohibited by or invalid under applicable law, such provision
shall be ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this
Participation Agreement.

         Section 11.8 Successors and Assigns; Transfers. This Participation
Agreement shall be binding upon the parties hereto and their respective
successors and assigns, and shall inure to the benefit of the parties hereto and
their respective successors and permitted assigns. Lessee may not assign any of
its rights and obligations under any Operative Agreement except as expressly
provided in the Operative Agreements.

         No Lessor shall assign, convey or otherwise transfer (including
pursuant to a participation) all or any portion of its right, title or interest
in, to or under any of the Operative Agreements, any Collateral and its interest
in the Equipment without the consent of Administrative Agent and, in the absence
of a continuing Event of Default, Lessee, except that without the prior written
consent of Administrative Agent or Lessee (x) any bank or similar financial or
commercial lending institution may pledge its interest in the ordinary course of
its business, provided, that no transfer upon a foreclosure pursuant to such a
pledge may occur unless the other provisions of this Section are complied with,
(y) any Lessor may transfer all or any portion of its interest to (A) any other
existing Lessor or (B) any Affiliate of such transferring Lessor and (z) any
Lessor may transfer any or all of such right, title and interest upon the
satisfaction of each of the following conditions:

         (a) Required Notice and Effective Date. Any Lessor desiring to effect a
transfer of its interest hereunder shall give written notice of each such
proposed transfer to Lessee and

                                      -36-

<PAGE>   42




Administrative Agent at least ten (10) days prior to such proposed transfer,
setting forth the name of such proposed transferee, the percentage or interest
to be retained by such Lessor, if any, and the date on which such transfer is
proposed to become effective. Except in the case of a transfer by a Lessor to
another existing Lessor or by a Lessor to an Affiliate, the transferring Lessor
shall pay to Administrative Agent a transfer fee of $3,000. In the event of a
transfer under this Section 11.8, any expenses incurred by the transferee in
connection with its review of the Operative Agreements and its investigation of
the transactions contemplated thereby shall be borne by such transferee or the
relevant Lessor, as they may determine, but shall not be considered costs and
expenses which Lessee is obligated to pay or reimburse under Section 11.5,
unless such transfer is being made pursuant to Section 7.6. No Lessor shall
effect a transfer of its interests hereunder to any Person not incorporated
under the laws of the United States or a State thereof unless such Person
delivers to the Administrative Agent, for the benefit of the Lessee, upon the
closing of such transfer, Forms 1001 or 4224 (or successor forms), in each case
certifying that such transferee is entitled to receive payments hereunder and
under the other Operative Agreements without deduction or withholding of any
United States Federal income taxes. The Administrative Agent shall transmit such
Forms to the Lessee immediately after such closing.

         (b) Assumption of Obligations. Any transferee pursuant to this Section
11.8 shall have executed and delivered to Administrative Agent a letter
substantially in the form of the Investor's Letter attached hereto as Exhibit F,
and thereupon the obligations of the transferring Lessor under the Operative
Agreements shall be proportionately released and reduced to the extent of such
transfer. Upon any such transfer as above provided, the transferee shall be
deemed to be bound by all obligations (whether or not yet accrued) under, and to
have become a party to, all Operative Agreements to which its transferor was a
party, shall be deemed the pertinent "Lessor" for all purposes of the Operative
Agreements and shall be deemed to have made that portion of the payments
pursuant to the Participation Agreement previously made or deemed to have been
made by the transferor represented by the interest being conveyed; and each
reference herein and in the other Operative Agreements to the pertinent "Lessor"
shall thereafter be deemed a reference to the transferee, to the extent of such
transfer, for all purposes. Upon any such transfer, Administrative Agent shall
deliver to each Lessor and Lessee a new Schedule I to this Participation
Agreement, revised to reflect the relevant information for such new Lessor and
the Commitment of such new Lessor (and the revised Commitment of the transferor
Lessor if it shall not have transferred its entire interest).

         (c) Employee Benefit Plans. No Lessor may make any such assignment,
conveyance or transfer to or in connection with any arrangement or understanding
in any way involving any employee benefit plan (or its related trust), as
defined in Section 3(3) of ERISA, or with the assets of any such plan (or its
related trust), as defined in Section 4975(e)(1) of the Code (other than a
governmental plan, as defined in Section 3(32) of ERISA), with respect to which
Lessee or such Lessor or any of their Affiliates is a party in interest within
the meaning of ERISA or a "disqualified person" within the meaning of the Code.


                                      -37-

<PAGE>   43




         (d) Amount of Commitment. Unless Lessee shall consent otherwise, no
Lessor may make any such assignment, conveyance or transfer if, as a consequence
thereof, the transferor (if such Lessor retains any part of its Commitment) or
transferee Lessor would have a combined Commitment and Outstanding Investment of
less than $5,000,000.

         (e) Representations and Warranties. Notwithstanding anything to the
contrary set forth above, no Lessor may assign, convey or transfer its interest
to any Person, unless such Person shall have delivered to Administrative Agent
and Lessee a certificate confirming the accuracy of the representations and
warranties set forth in Section 5.2 with respect to such Person (other than as
such representation or warranty relates to the execution and delivery of
Operative Agreements).

         Each transferee of a Lessor pursuant to this Section 11.8 shall be
entitled to the benefits of Articles VII and VIII; provided that no such
transferee shall be entitled to receive any greater amount pursuant to such
Sections than the transferor Lessor would have been entitled to receive in
respect of the amount of the Commitment transferred by such transferor Lessor to
such transferee if such transfer had not occurred.

         SECTION 11.9 JURY TRIAL. THE PARTIES WAIVE ANY RIGHT TO A TRIAL BY JURY
IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS UNDER THIS
PARTICIPATION AGREEMENT OR ANY OTHER OPERATIVE AGREEMENT OR UNDER ANY AMENDMENT,
INSTRUMENT, DOCUMENT OR AGREEMENT DELIVERED OR WHICH MAY IN THE FUTURE BE
DELIVERED IN CONNECTION HEREWITH OR THEREWITH OR ARISING FROM ANY RELATIONSHIP
EXISTING IN CONNECTION WITH THIS PARTICIPATION AGREEMENT OR ANY OPERATIVE
AGREEMENT AND AGREE THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A
COURT AND NOT BEFORE A JURY.

         Section 11.10 Captions; Table of Contents. Section captions and the
table of contents used in this Participation Agreement (including the exhibits
and schedules) are for convenience of reference only and shall not affect the
construction of this Participation Agreement.

         Section 11.11 FINAL AGREEMENT. THIS PARTICIPATION AGREEMENT, TOGETHER
WITH THE OTHER OPERATIVE AGREEMENTS, REPRESENT THE ENTIRE FINAL AGREEMENT
BETWEEN THE PARTIES WITH RESPECT TO THE TRANSACTIONS CONTEMPLATED HEREBY AND IN
THE OTHER OPERATIVE AGREEMENTS. THIS PARTICIPATION AGREEMENT CANNOT BE MODIFIED,
SUPPLEMENTED, AMENDED, RESCINDED OR CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES, EXCEPT BY AN
INSTRUMENT IN WRITING SIGNED BY THE PARTIES HERETO. THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN THE PARTIES.

         Section 11.12 No Third-Party Beneficiaries. Nothing in this
Participation Agreement or the other Operative Agreements shall be deemed to
create any right in any Person not a party hereto or

                                      -38-

<PAGE>   44




thereto (other than as set forth in Section 13.8 of the Lease and the permitted
successors and assigns of Lessors, Administrative Agent and Lessee), and such
agreements shall not be construed in any respect to be a contract in whole or in
part for the benefit of any third party except as aforesaid.

         Section 11.13 Further Assurances. Lessee, at its expense, will promptly
and duly execute and deliver all such documents and take such further action as
may be necessary or appropriate in order to effect the intent or purpose of this
Participation Agreement and the other Operative Agreements and to establish and
protect the rights and remedies created or intended to be created in favor of
the Lessors and Administrative Agent for the benefit of the Lessors, including,
without limitation, if requested by Required Lessors at the expense of Lessee,
the recording or filing of any Operative Agreement or any other document in
accordance with the laws of the appropriate jurisdictions.

         Section 11.14 Reproduction of Documents. This Participation Agreement,
all documents constituting Schedules or Exhibits hereto, and all documents
relating hereto received by a party hereto, including, without limitation: (a)
consents, waivers and modifications that may hereafter be executed; (b) the
Bills of Sale and all other documents received by the Lessors or Administrative
Agent in connection with the receipt and/or acquisition of the Equipment; and
(c) financial statements, certificates, and other information previously or
hereafter furnished to Administrative Agent or any Lessor may be reproduced by
the party receiving the same by any photographic, photostatic, microfilm,
micro-card, miniature photographic or other similar process. Each of the
Participants agrees and stipulates that, to the extent permitted by law, any
such reproduction shall be admissible in evidence as the original itself in any
judicial or administrative proceeding (whether or not the original is in
existence and whether or not such reproduction was made by such party in the
regular course of business) and that, to the extent permitted by law, any
enlargement, facsimile, or further reproduction of such reproduction shall
likewise be admissible in evidence.

         Section 11.15 Consideration for Consents to Waivers and Amendments.
Lessee hereby agrees that it will not, and that it will not permit any of its
Affiliates to, offer or give any consideration or benefit of any kind whatsoever
to any Lessor in connection with, in exchange for, or as an inducement to, such
Lessor's consent to any waiver in respect of, any modification or amendment of,
any supplement to, or any other consent or approval under, any Operative
Agreement unless such consideration or benefit is offered ratably to all
Lessors.

         Section 11.16 Submission to Jurisdiction. Any suit by Administrative
Agent or any Lessor to enforce any claim arising out of the Operative Agreements
may be brought in any state or Federal court located in New York, New York
having subject matter jurisdiction, and with respect to any such claim, each
Participant hereby irrevocably: (a) submits to the jurisdiction of such courts;
and (b) consents to the service of process out of said courts by mailing a copy
thereof, by registered mail, postage prepaid, to such Participant at its address
specified in this Participation Agreement, and agrees that such service, to the
fullest extent permitted by law: (i) shall be deemed in every respect effective
service of process upon it in any such suit, action or proceeding; and (ii)
shall be taken and held to be valid personal service upon and personal delivery
to it. Lessee irrevocably waives, to the

                                      -39-

<PAGE>   45




fullest extent permitted by law: (A) any claim, or any objection, that it now or
hereafter may have, that venue is not proper with respect to any such suit,
action or proceeding brought in such a court located in New York, New York
including, without limitation, any claim that any such suit, action or
proceeding brought in such court has been brought in an inconvenient forum; and
(B) any claim that Lessee is not subject to personal jurisdiction or service of
process in such forum. Lessee agrees that any suit to enforce any claim arising
out of the Operative Agreements or any course of conduct or dealing of
Administrative Agent or any Lessor shall be brought and maintained exclusively
in any state or Federal court located in New York, New York. Nothing in this
Section 11.16 shall affect the right of Administrative Agent or any Lessor to
bring any action or proceeding against Lessee or any Equipment or other
Collateral in the courts of any other jurisdiction. Lessee agrees that a final
judgment in any action or proceeding in a state or Federal court within the
United States may be enforced in any other jurisdiction by suit on the judgment
or in any other manner provided by law.

                                   DEFINITIONS


         The following terms (or other terms used or defined in any Operative
Agreement which have meanings substantially similar or equivalent to the
meanings assigned to such terms) shall have the following meanings for all
purposes, and such meanings shall be equally applicable both to the singular and
plural forms of the terms defined. Reference to schedules and exhibits in this
Schedule X shall mean Schedules and Exhibits attached to the Participation
Agreement, except as otherwise indicated. All references to "the Equipment" or
"all of the Equipment" or words of similar import shall be deemed to refer to
all Equipment covered by the Lease Supplements then in effect.

         Accounting Terms; Changes in GAAP. All accounting and financial terms
used herein and not otherwise defined herein and the compliance with each
covenant contained herein which relates to financial matters shall be determined
in accordance with GAAP applied by the Guarantor on a consistent basis, except
to the extent that a deviation therefrom is expressly stated. Should there be a
change in GAAP from that in effect on the Documentation Date, such that the
defined terms set forth in this Schedule X or the covenants set forth in the
Guaranty would then be calculated in a different manner or with different
components or would render the same not meaningful criteria for evaluating the
matters contemplated to be evidenced by such covenants, (a) the Guarantor, the
Lessee and the Lessors agree, within the 60-day period following any such
change, to negotiate in good faith and enter into an amendment to the Operative
Agreements in order to conform the defined terms set forth in this Section X or
the covenants set forth in the Guaranty, or both, in such respects as shall
reasonably be deemed necessary by the Required Lessors so that the criteria for
evaluating the matters contemplated to be evidenced by such covenants are
substantially the same criteria as were effective prior to any such change in
GAAP, and (b) the Guarantor shall be deemed to be in compliance with such
covenants during the 60-day period following any such change, or until the
earlier date of execution of such amendment, if and to the extent that the
Guarantor would have been in compliance therewith under GAAP as in effect
immediately prior to such change.

         Interpretation. (a) In the Operative Agreements, unless a clear
contrary intention appears:

                  (i) the singular number includes the plural number and vice
         versa;

                  (iv) reference to any Person includes such Person's successors

         individually, provided that nothing in this clause (iv) is intended to
         authorize any assignment not otherwise permitted by the Operative
         Agreements;

         Section or such Schedule or Exhibit of the applicable Operative
         Agreement;

         "include") shall mean including, without limiting the generality of any

         in effect from time to time.

                           (b) The Article and Section headings and the Table of
         Contents of any Operative Agreement are for convenience only and shall
         not affect the construction thereof.

                           (c) No provision of any Operative Agreement shall be
         interpreted or construed against any Person solely because that Person
         or its legal representative drafted such provision.

                                   ARTICLE II

                                   Lease Term

         Section 2.1 Interim and Base Periods. Unless earlier terminated, the

and (c) any Renewal Terms, if any, (collectively, the "Lease Term").

be the Initial Delivery Date (the "Lease Commencement Date").

         Section 2.3 Lease Renewal. Lessee may elect to renew this Lease on

of an Appraisal satisfactory to Lessors and upon the consent of all Lessors
(each, a "Renewal Term").

                         Rent; Other Economic Provisions

         Section 3.1 Rent Payments. Lessee shall pay to Administrative Agent,

<PAGE>   7




to Section 6.1. Except to the extent computations of interest are based upon
application of the Alternate Base Rate, all computations of interest pursuant to
the Operative Agreements shall be made on the basis of actual number of days
elapsed in a 360-day year.

         (a) Basic Rent. On each Payment Date during the Base Period, Lessee
shall pay to Administrative Agent, for the benefit of the Lessors, Basic Rent
consisting of the amount of Variable Rent accrued on the Lease Balance during
the Rent Period ended on such Payment Date.

         (b) Renewal Rent. On each Payment Date during any Renewal Term in
effect, if any, Lessee shall pay to Administrative Agent, for the benefit of the
Lessors, Renewal Rent under each Lease Supplement to which Lessee is a party,
consisting of the amount of Fixed Rent, if any, and Variable Rent determined by
Lessors based upon the results of the Appraisal required to be delivered under
Section 11.1(a) in connection with Lessee's exercise of its Renewal Option.

         (c) Selection of Rent Periods. During the Base Period or any Renewal
Term, if any, Lessee shall notify Administrative Agent not less than three
Business Days prior to the expiration of a Rent Period of its selection of one
or more Rent Periods to follow such expiring Rent Period and the amount of the
Lease Balance applicable to each such Rent Period so selected. Each such
notification shall be irrevocable.

         Section 3.2 Place and Manner of Payment. Rent and all other sums due to
Administrative Agent for the benefit of any Lessor hereunder shall be paid in
immediately available funds to Administrative Agent, in accordance with the
Administrative Agent's wire transfer instructions as it may from time to time
specify to Lessee in a notice pursuant to this Lease. All such payments shall be
received by Administrative Agent or such Lessor, as applicable, not later than
12:00 noon, Eastern time, on the date due; funds received after such time shall
for all purposes under the Operative Agreements be deemed to have been received
by Administrative Agent or such Lessor on the next succeeding Business Day. Any
payments received by Administrative Agent not later than 12:00 noon Eastern
time, shall be paid by Administrative Agent to the Lessors in immediately
available funds no later than 1:00 p.m. Eastern time on the same day and any
payments received by Administrative Agent from or on behalf of Lessee after
12:00 noon Eastern time, shall be paid to Lessors as soon after receipt as
practicable, but not later than 1:00 p.m. Eastern time on the next succeeding
Business Day. Lessee shall pay to Administrative Agent, for the benefit of the
Lessors, or to a Lessor in the case of payments to a Lessor, on demand, interest
at the rate per annum which is 2% above the Interest Rate in effect from time to
time on any overdue amount of Rent, or any other payment due under this Lease
and (to the extent permitted by applicable law) interest from the date due (not
taking into account any grace period) until payment is made.

         Section 3.3 Net Lease. This Lease is a net lease and Lessee's
obligation to pay all Rent, indemnities and other amounts payable hereunder
shall be absolute and unconditional under any and all circumstances and, without
limiting the generality of the foregoing, Lessee shall not be entitled to any
abatement or reduction of Rent or any setoff against Rent, indemnity or other
amount, whether arising by reason of any past, present or future claims of any
nature by Lessee against Administrative

                                       -3-

<PAGE>   8




Agent, Documentation Agent, Syndication Agent, Arranger or any Lessor. Except as
otherwise expressly provided herein, this Lease shall not terminate, nor shall
the obligations of Lessee be otherwise affected: (a) by reason of any defect in,
damage to, or loss of possession or use, obsolescence or destruction, of any or
all of the Equipment, however caused; or (b) by the taking or requisitioning of
any or all of the Equipment by condemnation or otherwise; or (c) by the
invalidity or unenforceability or lack of due authorization by Administrative
Agent, any Lessor or Lessee or other infirmity of this Lease; or (d) by lack of
power or authority of Administrative Agent, Documentation Agent, Syndication
Agent, Arranger or any Lessor to enter into this Lease or any other Operative
Agreement; or (e) by the attachment of any Lien of any third party to any item
of Equipment; or (f) by any prohibition or restriction of or interference with
Lessee's use of any or all of the Equipment by any Person; or (g) by the
insolvency of or the commencement by or against Administrative Agent, any Lessor
or Lessee of any bankruptcy, reorganization or similar proceeding; or (h) by any
other cause, whether similar or dissimilar to the foregoing. It is the intention
of the parties that all Rent, indemnities and other amounts payable by Lessee
hereunder shall be payable in all events in the manner and at the times herein
provided unless Lessee's obligations in respect thereof have been terminated or
modified pursuant to the express provisions of this Lease. To the extent
permitted by applicable law, Lessee hereby waives any and all rights which it
may now have or which may at any time be conferred upon it, by statute or
otherwise, to terminate, cancel, quit or surrender this Lease, in whole or in
part, except strictly in accordance with the express terms hereof. Each rental,
indemnity or other payment made by Lessee hereunder or under the other Operative
Agreements, shall be final, and Lessee shall not seek to recover all or any part
of such payment from Lessor for any reason whatsoever. Without affecting
Lessee's obligation to pay Rent, or other amounts payable hereunder or under the
other Operative Agreements, Lessee may seek damages for a breach by
Administrative Agent or any Lessor of its obligations under this Lease or the
Participation Agreement.


                                   ARTICLE IV

                                   Warranties

         Section 4.1 Warranty Disclaimer. LESSEE ACKNOWLEDGES AND AGREES THAT:
(a) EACH ITEM OF EQUIPMENT IS LEASED AS-IS AND WHERE-IS; (b) EACH ITEM OF
EQUIPMENT LEASED BY IT IS OF A SIZE, DESIGN, CAPACITY AND MANUFACTURE SELECTED
BY LESSEE; (c) LESSEE IS SATISFIED THAT THE SAME IS SUITABLE FOR ITS PURPOSES;
(d) LESSOR IS NOT A MANUFACTURER THEREOF OR A DEALER IN PROPERTY OF SUCH KIND;
AND (e) LESSOR HAS NOT MADE NOR SHALL IT BE DEEMED TO HAVE MADE: (i) ANY
REPRESENTATION OR WARRANTY OR COVENANT WITH RESPECT TO THE TITLE,
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, CONDITION, QUALITY,
DESCRIPTION, DURABILITY OR SUITABILITY OF ANY ITEM OF EQUIPMENT IN ANY RESPECT
OR IN CONNECTION WITH OR FOR THE PURPOSES AND USES OF LESSEE; OR (ii) ANY OTHER
REPRESENTATION OR

                                       -4-

<PAGE>   9




WARRANTY WHATSOEVER, EXPRESS OR IMPLIED, WITH RESPECT TO ANY ITEM OF
EQUIPMENT.

         Section 4.2 Quiet Enjoyment. In the absence of an Event of Default that
has occurred and is continuing, neither any Lessor nor the Administrative Agent
nor any Person acting by, through or under any of such Persons, shall take any
actions to interfere with Lessee's quiet enjoyment of the Equipment during the
Lease Term.


                                    ARTICLE V

                         Possession, Assignment, Use and
                            Maintenance of Equipment

         Section 5.1 Restriction on Lessee's Possession and Use. Lessee shall
not nor shall Lessee permit any Sublessee to: (a) use, operate, maintain or
store any item of Equipment or any portion thereof in violation of any
applicable insurance policy or law or regulation of any Authority; (b) except as
permitted by Section 6.1, abandon any item of Equipment; (c) except as permitted
by Section 5.2, sublease or assign, without the prior written consent of
Administrative Agent, any item of Equipment or permit the operation thereof by
anyone other than Lessee; (d) except as set forth in Section 5.2, sell, assign
or transfer any of its rights hereunder or in any item of Equipment, or directly
or indirectly create, incur or suffer to exist any Lien, on any of its rights
hereunder or in any item of Equipment, except for Permitted Liens; and (e) use,
operate, sublease, maintain or store any item of Equipment or any portion
thereof outside of the United States. Lessee will defend the transfer of the
Equipment by the seller thereof to Administrative Agent, for the benefit of the
Lessors or Administrative Agent against the claims or demands of all Persons
(other than Lessor Liens).

         Section 5.2 Subleases. So long as no Event of Default shall have
occurred and be continuing, Lessee may sublease one or more items of Equipment
to any other Person; provided that such items of Equipment (whether one or more)
are maintained in the United States or its territorial waters; and provided
further that any Sublease entered into pursuant to this Section 5.2 shall
satisfy each of the following conditions:

         (a) such Sublease shall be expressly subordinate and subject to this
Lease and the Liens created hereunder;

         (b) such Sublease shall be in writing and shall expressly prohibit any
further assignment, sublease or transfer of any rights or interests in the
Equipment;

         (c) such Sublease shall not contain a purchase option in favor of the
Sublessee or any other provision pursuant to which the Sublessee may obtain
record or beneficial title to the Equipment leased thereunder from Lessee of
such Equipment;


                                       -5-

<PAGE>   10




         (d) such Sublease shall prohibit the Sublessee from making any
alterations or modifications to the Equipment that would violate this Lease;

         (e) such Sublease shall not adversely affect the Lessors' interests and
rights in the Lease or the Equipment;

         (f) such Sublease shall require the Sublessee to maintain the Equipment
in accordance with Section 5.3 and to engage in activities with the Equipment in
a manner consistent with the Equipment's intended purpose and in accordance with
the Equipment's specifications;

         (g) on or before execution and delivery of such Sublease, Lessee shall
execute and deliver to Administrative Agent a security agreement, in a form
approved by Administrative Agent, whereby Lessee grants to Administrative Agent,
for the benefit of the Lessors, a security interest in all of Lessee's rights,
title and interest in, to and under such Sublease, as Collateral for Lessee's
obligations under the Operative Agreements. Upon the occurrence and during the
continuance of an Event of Default, Lessee shall deliver to Administrative Agent
an executed original counterpart of each Sublease upon the execution and
delivery thereof, marked as the sole original execution counterpart for Uniform
Commercial Code purposes, and Lessee shall, at its own cost and expense, do any
further act and execute, acknowledge, deliver, file, register and record any
further documents which Administrative Agent may reasonably request in order to
create, perfect, preserve and protect Administrative Agent's and Lessor's
security interest in such Sublease. Any payments received by Administrative
Agent from any Sublessee pursuant to this Section shall be credited to those
amounts owing by Lessee under the Lease;

         (h) Lessee shall not, without Administrative Agent's prior written
consent, permit or consent to any renewal or extension of a Sublease at any time
when an Event of Default has occurred and is continuing; and

         (i) Upon request by Administrative Agent at the direction of Required
Lessors, Lessee shall provide Administrative Agent with (i) a list of each
Sublease entered into by Lessee, which list shall include a description of the
Equipment to be leased thereunder, and (ii) if an Event of Default has occurred
and is continuing, copies of each Sublease.

The liability of Lessee with respect to this Lease, the Lease Supplements and
each of the other Operative Agreements shall not be altered or affected in any
way by the existence of any Sublease.

         Section 5.3 Maintenance. At all times during the term of this Lease,
Lessee shall at its expense or shall cause each Sublessee to: (a) maintain,
manage and monitor the Equipment in compliance in all material respects with all
applicable requirements of law, and any Authority and in compliance with all
insurance policies; (b) maintain each item of Equipment (or cause such Equipment
to be maintained) in as good operating order, repair and condition in accordance
with customary industry practices with respect to comparable equipment and
consistent with Lessee's maintenance practices with respect to comparable
equipment not covered by this Lease, ordinary

                                       -6-

<PAGE>   11




wear and tear excepted; (c) maintain, manage and monitor the Equipment in
accordance with the terms of all applicable contracts (including, without
limitation, service contracts and insurance contracts) in a manner consistent
with Lessee's customary practices; and (d) conduct all scheduled maintenance of
the Equipment in conformity with Lessee's maintenance procedures then in effect
for similar equipment owned or leased by Lessee, and applicable warranty
guidelines. Lessee shall in any event maintain the Equipment (or cause the
Equipment to be maintained) in at least as good a condition as comparable
equipment owned or leased by Lessee or any of its Affiliates. Lessee will
maintain or cause to be maintained, and shall permit Administrative Agent and
Lessors to inspect, any records, logs and other materials required by any
Authority having jurisdiction to be maintained or filed in respect of any item
of Equipment.

         Section 5.4  Repair, Replacement and Substitution.

         (a) As soon as practicable after a Partial Casualty to any item of
Equipment, Lessee shall repair and rebuild the affected portions of such
Equipment (or cause such affected portions to be repaired and rebuilt) to the
condition required to be maintained by Section 5.3. In the event that any Part
which may from time to time be incorporated or installed in or attached to any
item of Equipment becomes at any time worn out, damaged or permanently rendered
unfit for use for any reason whatsoever (unless such event constitutes a
Casualty, in which event the provisions of Section 6.1 hereof shall apply),
Lessee, at no charge to Administrative Agent or any Lessor, will promptly
replace, or cause to be replaced, such Part with a replacement Part (a
"Replacement Part") in accordance with Lessee's customary practices, but in any
event subject to Section 5.3. In addition, Lessee may, at its own cost and
expense, remove in the ordinary course of maintenance, service, repair, overhaul
or testing, any Part, whether or not worn out, destroyed, seized, confiscated,
damaged beyond repair or permanently rendered unfit for use; provided, that
Lessee will, at its own cost and expense, replace such Part with a Replacement
Part as promptly as is commercially reasonable. All Replacement Parts shall be
free and clear of all Liens (other than Permitted Liens) and shall be in as good
operating condition as, and shall have a value and utility at least equal to,
the Parts replaced, assuming such replaced Parts and the applicable item of
Equipment were in the condition and repair required to be maintained by the
terms of Section 5.3. Any Part at any time removed from any item of Equipment
shall remain the property of Administrative Agent, for the benefit of the
Lessors (subject to this Lease), no matter where located, until such time as
such Part shall be replaced by a Part which has been incorporated or installed
in or attached to such Equipment and which meets the requirements for a
Replacement Part specified above. Immediately upon any Replacement Part becoming
incorporated or installed in or attached to any such Equipment as above
provided, without further act: (i) title to the replaced Part (the "Replaced
Part") shall thereupon vest in Lessee, free and clear of all rights of
Administrative Agent, for the benefit of the Lessors, and shall no longer be
deemed a Part hereunder; (ii) such Replacement Part shall thereupon vest in
Lessors, as provided in Section 12.1 (in the same manner as the underlying
applicable item of Equipment); and (iii) such Replacement Part shall become
subject to this Lease, the security interest created hereunder, and the
applicable Lease Supplement, and shall be deemed part of such Equipment for all
purposes hereof to the same extent as the Parts incorporated or installed in or
attached to such Equipment on the date such Equipment became subject to this
Lease.

                                       -7-

<PAGE>   12




         (b) Upon the satisfaction of the conditions specified in Section
5.4(a), and the Replacement Part becoming subject to this Lease and the security
interest created hereunder, Administrative Agent, on behalf of the Lessors,
shall execute and deliver to Lessee such documents as may be reasonably
necessary to release the Replaced Part from the terms and scope of this Lease
(but without representations or warranties, except that the Replaced Part is
free and clear of all Lessor Liens), in such form as may be reasonably requested
by Lessee and are in form and substance satisfactory to the Required Lessors,
all at the expense of Lessee.

         (c) Provided no Event of Default has occurred or is continuing and if
this Lease shall not have previously terminated, Lessee shall have the option,
as hereinafter provided, to substitute equipment of "like kind" and of at least
equal value and utility ("Substituted Equipment"), for Equipment subject to this
Lease, provided, that (i) the aggregate Purchase Price of Equipment so
substituted over the Lease Term shall not exceed fifteen percent (15%) of the
aggregate Purchase Price of all of the Equipment originally subject to this
Lease without the consent of Administrative Agent and (ii) a new Appraisal for
the Equipment satisfactory to Required Lessors shall be delivered to the
Administrative Agent. On the date of any such substitution, Lessee shall deliver
to Lessor a Lease Supplement identifying such Substituted Equipment and transfer
to Lessor all right, title and interest in and to the Substituted Equipment.
Such Substituted Equipment shall become subject to this Lease and the security
interest created hereunder and Lessee shall execute and deliver such financing
statements and other documents as may be reasonably requested by Lessor to
reflect such security interest. Upon the substitution of Equipment as provided
herein, Lessor shall transfer to Lessee at Lessee's expense all of Lessor's
right, title and interest in and to the original Equipment subject to the
substitution without any representation or warranty.

         Section 5.5  Alterations, Modifications and Additions; Removable Parts.

         (a) Except as provided in Sections 5.3 and 5.4, Lessee shall not
remove, replace or alter any item of Equipment or affix or place any accessory,
equipment or device on any item of Equipment (such actions shall be hereafter
referred to collectively as "Alter") if such removal, replacement, alteration or
addition would materially impair the originally intended function or use or
materially reduce the value or useful life of such Equipment; provided, that
Lessee, at its own expense, will make, or cause to be made, any alteration,
improvement, modification or addition to or in respect of any item of Equipment
that may be necessary, from time to time, to comply in all material respects
with any applicable Law or to comply with any provision of any insurance policy
required to be maintained under Section 7.1 (any Parts being used to comply with
this provision shall be hereafter referred to as "Mandatory Parts"). All Parts
affixed to or installed as a part of any item of Equipment, excluding temporary
replacements, shall thereupon become subject to the security interest under this
Lease. If no Event of Default has occurred and is continuing, Lessee may remove,
at its expense, any Part at any time during the term of this Lease (such Part, a
"Removable Part") without any requirement to replace such Removable Part: (i)
which is in addition to, and not in replacement of or substitution for, any Part
originally incorporated or installed in or attached to any item of Equipment on
the date such item became subject to this Lease or any Part in replacement of or
substitution for any such Part originally incorporated or installed or attached
to such Equipment;

                                       -8-

<PAGE>   13




(ii) which is not a Mandatory Part; and (iii) which can be removed from any item
of Equipment without causing damage to such Equipment or diminishing or
impairing the value, utility or condition which such Equipment would have had at
such time had such addition not occurred; provided, that: (x) such removal will
not materially impair the value, use or useful life which such Equipment would
have had at such time had such Part not been affixed or placed to or on such
Equipment and (y) such Part is not necessary for the continued normal use of
such Equipment. Lessee shall repair all damage to any item of Equipment
resulting from any alteration so that such Equipment shall continue to be fit
for its intended purpose (ordinary wear and tear excepted). Neither
Administrative Agent nor any Lessor shall have any obligation to pay for or to
reimburse Lessee for any alteration required or permitted by this Section 5.5.

         (b) As provided in Section 4.1 of the Participation Agreement and
Section 12.1 of this Lease, all Parts incorporated or installed in or attached
or added to any item of Equipment as the result of alterations, modifications or
additions under this Section 5.5, except Removable Parts, shall, without further
act, vest in Administrative Agent, for the benefit of the Lessors, to secure
Lessee's performance of its obligations under the Operative Agreements, in the
manner provided in clause (ii) of Section 5.4(a) and the other applicable
provisions of Section 5.4 shall apply with respect to such Parts. Upon the
removal by Lessee of any Removable Part as provided herein, such Removable Part
shall no longer be deemed part of the Equipment from which it was removed. Any
Removable Part not removed by Lessee as provided herein prior to the end of the
Lease Term shall become the property of Lessor at such time.

         Section 5.6 Inspection of Collateral. Administrative Agent, the Lessors
and each of their agents and representatives shall have the right during regular
business hours, upon reasonable notice, to inspect any Collateral, including
without limitation any documentation related to the Collateral.


                                   ARTICLE VI

                 Risk of Loss; Replacement; Waiver and Indemnity

         Section 6.1 Casualty. Upon a Casualty, Lessee shall give prompt written
notice thereof (a "Casualty Notice") to Administrative Agent, which notice shall
specify whether Lessee will:

         (a) repay a portion of the Lease Balance equal to the Casualty Amount
together with all Variable Rent accrued on such portion of the Lease Balance to
the date of payment, which repayment shall be made no later than the next
scheduled Payment Date occurring after such Casualty or, if such Casualty occurs
during the last 5 Business Days of a Rent Period, then no later than the second
Payment Date occurring after such Casualty, provided that in any event such
repayment shall be made no later than the last day of the Lease Term (the
"Casualty Settlement Date"); or

         (b) replace the Equipment with respect to which the Casualty has
occurred pursuant to the provisions of Section 5.4 (treating such Equipment, for
these purposes, in the same manner as

                                       -9-

<PAGE>   14

a Part), provided that upon the occurrence and during the continuance of an
Event of Default or an Incipient Default, Lessee shall be obligated, at the
option of the Required Lessors, to make the payments referred to in clause (a)
above and shall not be entitled to exercise any right or election of replacement
as set forth in this clause (b).

         If Lessee has elected, or is required, to pay the Casualty Amount
pursuant to clause (a) above, Lessee shall continue to make all payments of Rent
due under the Lease Supplement until and including the Casualty Settlement Date.
Upon payment of the Casualty Amount in respect of any item of Equipment
suffering a Casualty on such Casualty Settlement Date, the remaining scheduled
payments of Fixed Rent, if any, shall each be reduced by an amount equal to the
product of the scheduled amount of such Fixed Rent prior to the receipt of such
payment by Administrative Agent multiplied by the Allocation Fraction under the
Lease Supplement of the Equipment suffering such Casualty.

         Section 6.2 Casualty Proceeds. All proceeds of any casualty insurance
or condemnation proceeds ("Casualty Proceeds") paid or payable to Lessee or any
Affiliate of Lessee by reason of a Casualty or Partial Casualty to any item of
Equipment shall be deposited into a deposit account established by
Administrative Agent, for the benefit of the Lessors (the "Deposit Account"),
for purposes of funding Lessee's compliance with the applicable provisions of
Section 5.4 or 6.1 with respect to such Casualty or Partial Casualty. The
balance in the Deposit Account shall be invested in overnight cash equivalent
investments. Any Casualty Proceeds paid to Administrative Agent with respect to
any item of Equipment suffering a Casualty or a Partial Casualty shall also be
deposited in the Deposit Account. Any moneys in the Deposit Account and all
proceeds thereof attributable to a Casualty or Partial Casualty shall be
remitted promptly to Lessee upon Lessee's written certification to Lessor that
the proceeds of the Deposit Account have been, or are to be, used to comply with
Section 6.1 or Section 5.4, as applicable. Notwithstanding the foregoing
provisions of this Section 6.2, and provided that no Incipient Default
consisting of an event described in Section 8.1 (a) or (g) and no Event of
Default has occurred and is continuing, if the aggregate amount of Casualty
Proceeds at any one time outstanding is $1,000,000 or less, then Lessee shall
receive such Casualty Proceeds directly, without delivery to Administrative
Agent; provided, that such Casualty Proceeds are applied in accordance with the
requirements of Section 6.1 or Section 5.4, as applicable. Notwithstanding any
Casualty, all of Lessee's obligations under this Lease and the Lease Supplement
(including its obligation to make all payments of Rent as they become due) shall
continue unabated and in full force and effect as provided in this Lease.
Without limiting the foregoing, Lessee's obligations under Section 5.4 shall not
be affected by the amount of any Casualty Proceeds received by Lessee.

                                    Insurance

         Section 7.1 Required Coverages. At its own expense, Lessee will
maintain or cause to be maintained, with financially responsible companies
selected by Lessee and having an A.M. Best rating of "A" or better or otherwise
acceptable to the Required Lessors, insurance with respect to its property and
business against such liabilities, casualties, risks and contingencies and in
such types and amounts as is customary for Guarantor as to similar equipment
owned, located or operated by it, but in the case of property damage, in no
event less than the Lease Balance. Such insurance shall (i) name Administrative
Agent and Lessors as additional insured parties or, in the case of property
insurance, loss payees thereunder as specified above (without any representation
or warranty by, or obligation upon, Administrative Agent or any Lessor) as their
respective interests may appear, (ii) contain the agreement by the insurer that
any loss thereunder shall be payable to Administrative Agent and Lessors
notwithstanding any action, inaction or breach of representation or warranty by
Lessee or any other Person having an interest in any item of Equipment
(including, without limitation, Administrative Agent or any Lessor), (iii)
provide that there shall be no recourse against Administrative Agent or any
Lessor for payment of premiums or other amounts with respect thereto, (iv)
provide that insurer shall give Administrative Agent and each Lessor at least 30
days' prior written notice of cancellation, lapse or reduction of limits, (v) be
primary with respect to any other insurance carried by or available to
Administrative Agent and the Lessors, (vi) provide that the insurer shall waive
any right of subrogation, setoff, counterclaim, or other deduction, whether by
attachment or otherwise, against Administrative Agent or any Lessor, and (vii)
contain a cross-liability clause providing for coverage of Administrative Agent
and each Lessor as if separate policies had been issued to each of them,
provided, however, that such provision shall not increase the total limits of
liability over those specified herein. Lessee will notify Administrative Agent
and Lessors promptly of any policy cancellation, reduction in policy limits,
modification or amendment.

         Section 7.2 Delivery of Insurance Certificates. On or before the
Initial Delivery Date, Lessee shall deliver to Administrative Agent certificates
of insurance satisfactory to Administrative Agent and Lessors evidencing the
existence of all insurance required to be maintained hereunder and setting forth
the respective coverages, limits of liability, carrier, policy number and period
of coverage. Thereafter, throughout the Lease Term, at the time each of Lessee's
insurance policies is renewed (but in no event less frequently than once each
year), Lessee shall deliver to Administrative Agent, for the benefit of Lessors,
certificates of insurance evidencing that all insurance required by Section 7.1
to be maintained by Lessee with respect to the Equipment is in effect within ten
(10) days after renewal.

pursuant to Section 9.3 of the Participation Agreement) exercise in any order
one or more or all of the remedies set forth in this Section 8.2 (it being
understood that no remedy herein conferred is intended to be exclusive of any
other remedy or remedies, but each and every remedy shall be cumulative and
shall be in addition to every other remedy given herein or now or hereafter
existing at law or in equity or by statute):

         (a) Administrative Agent may proceed by appropriate court action or
actions, either at law or in equity, to enforce performance by Lessee of the

                                      -14-

<PAGE>   19




or any other law; (iii) enter upon the premises where any item of Equipment may
be and either remove such Equipment, with any damage to the improvements on such
premises to be borne by Lessee (except to the extent such damage is due to the
willful misconduct or gross negligence of Administrative Agent or its
representatives), or take possession of such Equipment; and (iv) require Lessee
to return the Equipment as provided in Article IX; or

         (c) Administrative Agent may require Lessee immediately to purchase the

accrued unpaid Rent payable on or prior to such Payment Date; (ii) the pro rata
Variable Rent from the most recent Payment Date to the date of such purchase;
and (iii) all other fees and expenses and other amounts then due and payable
pursuant to this Lease and the other Operative Agreements.

         Notwithstanding the foregoing, so long as any Event of Default
described in subsections (a) through (e) and (h) through (m) of Section 8.1
shall have occurred and be continuing, and upon notice by the Administrative
Agent to Lessee that the Administrative Agent seeks to pursue any of the
remedies described in Section 8.2, Lessee may, within one (1) Business Day from

Default described in subsection (f) or (g) of Section 8.1, Lessee shall

in Section 8.2, if any Event of Default shall occur and be continuing, the
Administrative Agent may (at the direction of the Required Lessors pursuant to
Section 9.3 of the Participation Agreement), but is not required to, sell the
Collateral in one or more sales. Administrative Agent, on behalf of Lessors, may
purchase all or any part of the Collateral at such sale. Lessee acknowledges
that sales for cash or on credit to a wholesaler, retailer or user of such
Collateral, at a public or private auction, are all commercially

                                      -15-

reasonable. Any notice required by law of intended disposition by Administrative
Agent shall be deemed reasonable and properly given if given at least 10 days
before such disposition.

         Section 8.4 Proceeds of Sale; Deficiency. All payments received and
amounts held or realized by Administrative Agent at any time when an Event of
Default shall have occurred and be continuing and after, pursuant to Section
8.2, the Lease Balance shall have been accelerated or Lessee is required to
purchase the Equipment, as well as all payments or amounts then held or
thereafter received by Administrative Agent shall be distributed forthwith upon
receipt by the Administrative Agent in the following order of priority:

                  first: (i) so much of such payments or amounts as shall be
         required to reimburse first the Administrative Agent and then any
         Lessor for any tax (other than any income tax payable on interest not
         required to be indemnified by Lessee under Article VIII of the
         Participation Agreement and on fees and other compensation of the
         Administrative Agent), expense or other amount owed to Administrative
         Agent or any Lessor in connection with the collection or distribution
         of such payments or amounts to the extent not previously reimbursed by
         Lessee (including, without limitation, the expenses of any sale, taking
         or other proceeding, expenses in connection with realizing on any of
         the Collateral, reasonable attorneys' fees and expenses (including the
         allocated costs of internal counsel), court costs and any other
         reasonable expenditures incurred or reasonable expenditures or advances
         made by Administrative Agent or any Lessor in the protection, exercise
         or enforcement of any right, power or remedy upon such Event of Default
         whether pursuant to Section 8.2 or otherwise) shall be so applied by
         Administrative Agent first to itself and then to such Lessors; and (ii)
         so much of such payments or amounts as shall be required to pay the
         reasonable fees and compensation of Administrative Agent in connection
         with acting as Administrative Agent not previously paid by Lessee,
         shall be distributed to Administrative Agent;

                  second: so much of such payments or amounts except those
         specified in clause third below, which under the terms of this Lease
         and the other Operative Agreements have accrued, including, without
         limitation, such amounts as shall be required to reimburse the then
         existing or prior Lessors for payments made by them to Administrative
         Agent pursuant to Section 9.4 of the Participation Agreement (to the
         extent not previously reimbursed);

                  third: so much of such payments or amounts remaining as shall
         be required to pay in full, in the following order of application, (a)
         all accrued unpaid Variable Rent (including, to the extent permitted by
         applicable law, interest on interest) and (b) the aggregate unpaid
         Lease Balance, and in case the aggregate amount so to be distributed
         shall be insufficient to pay any of the foregoing in full all as
         aforesaid then, ratably to the Lessors in accordance with their
         respective Commitment Percentages; and

                  fourth: so much of such payments or amounts as shall remain
         shall be distributed to Lessee.

         Section 8.5 Right to Perform Lessee's Agreements. If Lessee fails to
perform any of its agreements contained herein or in any other Operative
Agreement within the time period specified therefor, so long as no Event of
Default has occurred and is continuing, Administrative Agent, upon written
instructions from Required Lessors and receipt by Administrative Agent (and one
or more Lessors) of indemnification satisfactory to it, and, upon 3 Business
Days' prior notice to Lessee, may perform such agreement and the fees and
expenses incurred by Administrative Agent (or one or more Lessors) in connection
with such performance together with interest thereon shall be payable by Lessee
upon demand. Interest on fees and expenses so incurred by Administrative Agent
(or one or more Lessors) shall accrue at the rate provided in Section 3.2 for

                               Return of Equipment

         If Administrative Agent has terminated this Lease pursuant to Section
8.2, and Lessee has not elected to purchase the Equipment pursuant to Section
8.2 or Articles X or XI, Lessee shall (a) maintain (or cause to be maintained)
the Equipment in the condition required by Section 5.3, store the Equipment for
up to one year following such termination without cost to Administrative Agent
or any Lessor and keep all of the Equipment insured in accordance with Article
VII, and (b) upon such termination forthwith package and deliver without cost to
the Administrative Agent or any Lessor exclusive possession of such Equipment to
Administrative Agent, for the benefit of the Lessors, at a location in the
continental United States (excluding Alaska) designated by Administrative Agent,
together with a copy of an inventory list of the Equipment then subject to the
Lease, all then current plans, specifications and operating, maintenance and
repair manuals relating to the Equipment that have been received or prepared by
Lessee, appropriately protected and in the condition required by Section 5.3

Administrative Agent. This Article IX shall survive termination of this Lease.


                                    ARTICLE X

                                Early Termination

         On any scheduled Payment Date after the Lease Commencement Date Lessee
may, at its option, upon at least 30 days' advance written notice from Lessee to
Administrative Agent and the Lessors, purchase all, but not less than all, of
the Equipment subject to all Lease Supplements then in effect for a purchase
price payable in immediately available funds in an amount equal to the Lease

(i) all accrued unpaid Rent payable on or prior to such Payment Date and (ii)
all other fees and expenses and other

                                      -17-

amounts then due and payable pursuant to this Lease and the other Operative
Agreements. Upon the payment in full of such sums by wire transfer of
immediately available funds by Lessee in accordance with the provisions of the
preceding sentence, the obligation of Lessee to pay Rent hereunder shall cease,
the term of this Lease shall end on the date of such payment and Administrative
Agent, on behalf of Lessors, shall execute and deliver to Lessee such documents
as may be reasonably required to release the Equipment from the terms and scope
of this Lease (without representations or warranties, except that the Equipment
is free and clear of Lessor Liens), in such form as may be reasonably requested
by Lessee, all at Lessee's sole cost and expense.


                                   ARTICLE XI

                                Lease Termination

         Section 11.1 Options. Not later than 180 days prior to the last day of
the Base Period or any Renewal Term, if any, Lessee shall, by delivery of
written notice to Administrative Agent, exercise one of the following options:

         (a) elect to renew this Lease with respect to all, but not less than
all, of the Equipment then subject hereto (the "Renewal Option") with respect to
the Base Period or Renewal Term then in effect, with each such Renewal Term
commencing on the last day of the Base Period or Renewal Term then in effect,
with such renewal to be effective only if agreed to by Lessors, for such period
of time and upon such terms and conditions as are mutually acceptable to Lessee
and Lessors, provided, that (i) such option shall be exercised only with respect
to the Base Period or Renewal Term then in effect and (ii) in connection with
the exercise of the Renewal Option Lessee shall provide Lessors with an
Appraisal of all of the Equipment subject to this Lease together with its notice
of exercise, which Appraisal shall set forth the Appraisal Values of the
Equipment as of the commencement of each Renewal Term and as of the end of each
Renewal Term and shall be satisfactory to all Lessors; or

         (b) purchase in immediately available funds in an amount equal to the
Lease Balance all, but not less than all, of the Equipment then subject to this
Lease on the last day of the Base Term or any Renewal Term, on the terms and
conditions set forth in Section 11.2. (the "Lessee Purchase Option"); provided,
that such option shall be exercised only with respect to all Equipment then
subject to this Lease; or

         (c) sell on behalf of the Lessors to a purchaser or purchasers not in
any way affiliated with Lessee all, but not less than all, of the Equipment then
subject to this Lease on the last day of the Base Period or any Renewal Term
then in effect with respect to which such option is exercised, on the terms and

Lessee's election of the Lessee Purchase Option will be irrevocable at the time
made, but if Lessee fails to make a timely election, Lessee will be deemed to
have irrevocably elected the Lessee Purchase Option. In addition, the Sale
Option shall automatically be revoked if there exists an Incipient Default or
Event of Default at anytime after the Sale Option is properly elected and
Administrative Agent shall be entitled to exercise all rights and remedies
provided in Article VIII. Lessee may not elect the Sale Option if there exists
on the date the election is made an Event of Default that is continuing or an
Incipient Default.

         Section 11.2 Lessee Purchase Option. If Lessee elects the Lessee
Purchase Option, then on the Termination Date Lessee shall purchase all (but not
less than all) of the Equipment for an amount equal to the Lease Balance. Lessee
shall also pay to Administrative Agent all accrued unpaid Rent and all other
amounts, if any then due and owing hereunder. Upon the payment in full of such
sums by wire transfer of immediately available funds by Lessee in accordance
with the provisions of the preceding sentence, the obligation of Lessee to pay
Rent hereunder with respect to such Equipment shall cease, the term of this
Lease with respect to such Equipment shall end on the date of such payment and
Administrative Agent, on behalf of Lessors, shall execute and deliver to Lessee
such documents as may be reasonably required to release such Equipment from the
terms and scope of this Lease (without representations or warranties, except
that such Equipment is free and clear of Lessor Liens), in such form as may be
reasonably requested by Lessee, all at Lessee's sole cost and expense.

         Section 11.3 Sale Option. If Lessee elects the Sale Option, then during
the period prior to the Termination Date Lessee, as agent for Administrative
Agent and Lessors and at no expense to Administrative Agent and Lessors, shall
use its commercial best efforts to obtain bids for the purchase of all of the
Equipment in immediately available funds on such Termination Date from
prospective purchasers which are unaffiliated with Lessee and are financially
capable of purchasing the Equipment ("Qualified Purchasers"). Administrative
Agent may also, if it so desires, seek to obtain such bids. All bids received by
Lessee or Administrative Agent, within five Business Days after receipt thereof,
shall be certified to the other in writing setting forth the name and address of
the party submitting each such bid and the amount and terms thereof.

         If any bid is received from a Qualified Purchaser for an amount in
excess of the Lessor Risk Amount or if the Required Lessors agree in their sole
and absolute discretion to accept a bid for less than such Lessor Risk Amount,
then on such Termination Date (i) the Equipment shall be sold on an "as-is,"
"where-is" basis (without recourse to or representation or warranty from
Administrative Agent and Lessors, except that the Equipment is free and clear of
Lessor Liens), to the bidder, which is a Qualified Purchaser, selected by Lessee
after consultation with Administrative Agent (the "Purchaser"), provided,
however, that the Required Lessors may not reject the highest bidder if the next
highest bid is not at least equal to such Lessor Risk Amount; (ii) Lessee shall
make the Equipment available to the Purchaser in the same manner and in the same
condition and otherwise in accordance with this Lease as if delivery were made
to Administrative Agent pursuant to Article IX, (iii) such Purchaser shall pay
the sale proceeds in immediately available funds to Administrative Agent for the
benefit of Lessors, to be distributed as provided in the next paragraph

                                      -19-

of this Section, (iv) Lessee shall pay to Administrative Agent, for the benefit
of Lessors, in immediately available funds (x) all accrued unpaid Rent and all
other amounts, if any then due and owing under this Lease, and (y) an amount
equal to the excess, if any, of (A) the Lease Balance as of the Termination Date
over (B) the sale proceeds (but in no event shall such amount payable by Lessee
under this clause (y) exceed the Lessee Risk Amount), to be distributed as
provided in the next paragraph of this Section, (v) title to such Equipment
shall be transferred to such Purchaser, free and clear of Lessor Liens, and (vi)
Administrative Agent, on behalf of Lessors, shall execute and deliver to
Purchaser such documents as may be reasonably required to release such Equipment
from the terms and scope of this Lease (without representations or warranties,
except that such Equipment is free and clear of Lessor Liens), in such form as
may be reasonably requested by Purchaser.

         Sales proceeds referred to in clause (iii) of the preceding paragraph
and other amounts referred to in clause (iv)(y) of the preceding paragraph shall
be distributed as follows, provided that if ABN AMRO Bank N.V.'s proportionate
share of the Total Commitment increases or decreases from its current Commitment
of fifteen percent (15%), a corresponding adjustment shall be made to the
percentages set forth in clauses (a) and (b) below:

                  (a) all sales proceeds up to the Lessor Risk Amount shall be
         distributed 78.81% to the Lessors (other than ABN AMRO Bank N.V.) (the
         "Other Lessors") on a pro rata basis, and 21.19% to ABN AMRO Bank N.V.;

                  (b) all sales proceeds in excess of the Lessor Risk Amount (up
         to the Lessee Risk Amount) and the amount calculated under clause
         (iv)(y) of the immediately preceding paragraph shall be distributed
         86.05% to the Other Lessors on a pro rata basis, and 13.95% to ABN AMRO
         Bank N.V.; and

                  (c) all sales proceeds remaining after payment of the Lease
         Balance, plus all Rent and other amounts due and payable under this
         Lease and any other Operative Agreement, shall be distributed to
         Lessee.

         If (x) Administrative Agent does not receive any bid in excess of the
aggregate Lessor Risk Amount from a Qualified Purchaser or Administrative Agent
does not accept any bids received for less than the Lessor Risk Amount prior to
the Termination Date, Lessee shall have the option to, or (y) the proposed sale
to the Purchaser is not consummated prior to the Termination Date, Lessee shall
be required to, purchase such Equipment by paying to Administrative Agent within
ten (10) Business Days of the Termination Date, in immediately available funds
in an amount equal to the Lease Balance as of the Termination Date. In the event
Lessee exercises such option or is so required to purchase such Equipment,
Lessee shall also pay to Administrative Agent (i) all accrued unpaid Rent
payable on such Termination Date; (ii) the pro rata Variable Rent from the
Termination Date to the date of such purchase; and (iii) all other fees and
expenses and other amounts then due and payable pursuant to this Lease and the
other Operative Agreements. If Lessee has the option to, but does not so elect
to, purchase all of the Equipment pursuant to the immediately preceding
sentence, Lessee shall pay to Administrative Agent an amount equal to (i) the
Lessee Risk Amount

                                      -20-

plus (ii) the indemnity for Excessive Use set forth in Section 7.2 of the
Participation Agreement; Administrative Agent shall retain title to such
Equipment and Lessee shall return such Equipment to Administrative Agent in
accordance with Article IX.


                                   ARTICLE XII

                          Ownership, Grant of Security
                    Interest to Lessor and Further Assurances

         Section 12.1 Grant of Security Interest. Lessee hereby assigns, grants
and pledges to Administrative Agent, for the benefit of the Lessors, a security
interest in all of Lessee's right, title and interest, whether now or hereafter
existing or acquired, in the Collateral, to secure the payment and performance
of all obligations of Lessee now or hereafter existing under this Lease or any
other Operative Agreement. Lessee shall, at its expense, do any further act and
execute, acknowledge, deliver, file, register and record any further documents
which Administrative Agent or any Lessor may reasonably request in order to
protect its title to and perfected security interest in the Collateral, subject
to no Liens other than Permitted Liens, and Administrative Agent's rights and
benefits under this Lease. Lessee shall promptly and duly execute and deliver to
Administrative Agent such documents and assurances and take such further action
as Administrative Agent or any Lessor may from time to time reasonably request
in order to carry out more effectively the intent and purpose of this Lease and
the other Operative Agreements, to establish and protect the rights and remedies
created or intended to be created in favor of Administrative Agent hereunder and
thereunder, and to establish, perfect and maintain the right, title and interest
of Administrative Agent, for the benefit of the Lessors, in and to the
Collateral, subject to no Lien other than Permitted Liens, or of such financing
statements or fixture filings or other documents with respect hereto as
Administrative Agent or any Lessor may from time to time reasonably request, and
Lessee agrees to execute and deliver promptly such of the foregoing financing
statements and fixture filings or other documents as may require execution by
Lessee. Without limiting the foregoing, on and after the date Lessee elects or
is deemed to have elected the Sale Option, Administrative Agent shall have the
unconditional right to demand the execution and delivery by Lessee of bills of
sale with respect to the Equipment leased by Lessee or such documentation as may
be necessary to cause title to the Equipment to be recorded in the name of
Administrative Agent, for the benefit of the Lessors. To the extent permitted by
applicable laws, Lessee hereby authorizes any such financing statements and
other documents to be filed without the necessity of the signature of Lessee, if
Lessee has failed to sign any such instrument within 10 days after request
therefor by Administrative Agent or any Lessor. Upon Lessee's request,
Administrative Agent shall at such time as all of the obligations of Lessee
under this Lease or any other Operative Agreements have been indefeasibly paid
or performed in full (other than Lessee's contingent obligations, if any, under
Articles VII and VIII of the Participation Agreement), execute and deliver such
bills of sale (without representations or warranties, except as to the absence
of Lessor Liens), termination statements and other appropriate documentation
reasonably requested by Lessee, all at Lessee's expense, to evidence
Administrative Agent's transfer of title to and release of its security interest
in the Collateral. At such time,

                                      -21-

<PAGE>   26




Administrative Agent shall execute and deliver to Lessee such documents as may
be reasonably necessary (without representations or warranties, except that the
Equipment is free and clear of Lessor Liens) to transfer title to and release
Administrative Agent's security interest in the Equipment. Any such sale of the
Equipment to either Lessee or a third party shall be on an AS-IS, WHERE-IS basis
(without representations or warranties, except that the Equipment is free and
clear of Lessor Liens).

         Section 12.2 Retention of Proceeds in the Case of Default. If Lessee
would be entitled to any amount (including any Casualty Proceeds or Partial
Casualty Proceeds) but for the existence of any Event of Default or Incipient
Default, Administrative Agent shall hold such amount as part of the Collateral
and shall be entitled to apply such amounts against any amounts due hereunder;
provided, that Administrative Agent shall distribute such amount or transfer
such Equipment in accordance with the other terms of this Lease if and when no
Event of Default is then continuing or Incipient Default exists.

         Section 12.3 Attorney-in-Fact. Lessee hereby irrevocably appoints
Administrative Agent as Lessee's attorney-in-fact, with full authority in the
place and stead of Lessee and in the name of Lessee or otherwise, from time to
time in Administrative Agent's discretion, upon the occurrence and during the
continuance of an Event of Default, to take any action (including any action
that Lessee is entitled to take) and to execute any instrument which
Administrative Agent or the Required Lessors may deem necessary or advisable to
accomplish the purposes of this Lease (subject to any limitations set forth in
the Operative Agreements), including, without limitation:

         (a) to ask, demand, collect, sue for, recover, compromise, receive and
give acquittance and receipts for money due and to become due under or in
connection with the Collateral;

         (b) to receive, endorse and collect any drafts or other instruments,
documents and chattel paper in connection with the foregoing clause (a);

         (c) to file any claim or take any action or institute any proceedings
which Administrative Agent may deem to be necessary or advisable for the
collection thereof or to enforce compliance with the terms and conditions of any
Collateral; and

         (d) to perform any affirmative obligations of Lessee hereunder.

Lessee hereby acknowledges, consents and agrees that the power of attorney
granted pursuant to this Section 12.3 is irrevocable and coupled with an
interest.

         Section 12.4 Release of Liens. Upon the replacement or substitution of
any item of Equipment or Part or Sublease, or the payment of all amounts
required pursuant to Section 6.1 in connection with a Casualty, in each case in
compliance with the applicable provisions of the Lease, such Equipment or Part
or Sublease shall be released from the security interest created hereunder as
provided in Section 5.4(b) or (c).

         Section 13.1 No Waiver. No delay or omission in the exercise of any
right, power or remedy accruing to Administrative Agent and/or the Lessors upon
any breach or default of Lessee hereunder shall impair any such right, power or
remedy, nor shall it be construed to be a waiver of any such breach or default,
or an acquiescence therein or of or in any similar breach or default thereafter
occurring, nor shall any single or partial exercise of any right, power or
remedy preclude other or further exercise thereof, or the exercise of any other
right, power or remedy, nor shall any waiver of any single breach or default be
deemed a waiver of any other breach or default theretofore or thereafter
occurring. Any waiver, permit, consent or approval of any kind or character on
the part of Administrative Agent or the Lessors of any breach or default under
this Lease must be specifically set forth in writing and must satisfy the
requirements set forth in Article X of the Participation Agreement with respect
to approval by Administrative Agent or the Lessors.

         Section 13.2 Survival of Covenants. All claims pertaining to the
representations, warranties and covenants of Lessee under Articles II, III, IV,

any such termination.

modification, amendment or waiver of this Lease, including any schedules or
exhibits hereto, or any other Operative Agreement to which Administrative Agent
or any Lessor is a party shall be valid unless the same shall have been entered
into in accordance with Article X of the Participation Agreement.

         Section 13.5 Notices. All notices, demands, requests, consents,
approvals and other instruments hereunder shall be in writing and shall be
deemed to have been properly given if given as provided for in Section 11.4 of
the Participation Agreement.

         Section 13.6 Counterparts. This Lease has been executed in several
counterparts. One counterpart has been prominently marked "Administrative
Agent's Copy." Only the counterpart marked "Administrative Agent's Copy" shall
evidence a monetary obligation of or shall be deemed to be an original or to be
chattel paper for purposes of the Uniform Commercial Code, and such copy shall
be held by Administrative Agent.

         Section 13.7 Severability. Whenever possible, each provision of this
Lease shall be interpreted in such manner as to be effective and valid under
applicable law; but if any provision of

                                      -23-

transfer or otherwise dispose of its rights or delegate its obligations under
this Lease to any other Person, except as permitted or required by Section 5.2
hereof or the Participation Agreement. Notwithstanding the foregoing,
Administrative Agent, on behalf of Lessors, acknowledges and agrees that (i)
Lessee intends to transfer its gas compression business after the Initial
Delivery Date to a joint venture entity to be formed with General Electric
Capital Corporation or an Affiliate thereof (the "Transferee") as previously
disclosed to Lessors (the "Business Transfer") and that the Business Transfer
will involve transfer of the Equipment and Lessee's rights and obligations under
the Operative Agreements to the Transferee, and (ii) Administrative Agent and
Lessors intend to permit such a transfer provided that: (A) no Event of Default
has occurred and is continuing or will result therefrom, (B) the Transferee
assumes the obligations of Lessee under the Operative Agreements and makes
representations and warranties to Administrative Agent and Lessors similar to
those made by Lessee in the Operative Agreements pursuant to an instrument
satisfactory to Lessors, (C) the structure of the Business Transfer and the
Transferee will be as has been previously represented to Administrative Agent
and Lessors by Guarantor and (D) Lessee, Transferee and Guarantor, as

Transfer and protect the interests of Administrative Agent and Lessors in the
Collateral and under the Operative Agreements.

                               GUARANTY AGREEMENT

         This GUARANTY AGREEMENT, dated as of December 8, 1998 (as the same may
be amended from time to time, this "Guaranty"), is executed by and between
WEATHERFORD INTERNATIONAL, INC., a Delaware corporation ("Guarantor"), and ABN
AMRO BANK N.V., as Administrative Agent for the Lessors ("Administrative
Agent").

                             Preliminary Statement

         A.      As contemplated by (i) the Participation Agreement, dated as
of the date hereof (as amended, the "Participation Agreement"), among
Weatherford Enterra Compression Company, L.P., a Delaware limited partnership,
as Lessee ("Lessee"), Administrative Agent, Syndication Agent, Arranger, Chase
Bank of Texas, National Association, as Documentation Agent and the Lessors
identified therein and (ii) the Master Lease Intended as Security dated as of
the date hereof (as amended, the "Lease"), between the Administrative Agent, as
an administrative agent for the Lessors, and the Lessee, the Administrative
Agent will lease the Equipment to the Lessee, a limited partnership controlled
by the Guarantor.  All capitalized terms used and not otherwise defined herein
shall have the meanings assigned to such terms in Schedule X to the
Participation Agreement.

         B.      The execution, delivery and performance by the Guarantor of
this Guaranty are conditions precedent to the execution, delivery and
performance by the Agents and the Lessors of the Operative Agreements.

         NOW, THEREFORE, in consideration of the mutual covenants and
agreements set forth herein and intending to be legally bound by this Guaranty,
the Guarantor and the Administrative Agent hereby agree as follows:


                                   ARTICLE I

                              GUARANTY AND PAYMENT

                 SECTION 1.01  Guaranty.  The Guarantor hereby unconditionally
and irrevocably guarantees to and agrees with the Administrative Agent,
Documentation Agent, Syndication Agent, Arranger and the Lessors that:

                 (a)      The Rent and all other amounts payable by the Lessee
under the Operative Agreements, including, without limitation, Lease Balance,
Lessee Risk Amount, Termination Value and any and all indemnification
obligations of the Lessee, will be promptly paid in full when due in accordance
with the provisions thereof; and

                 (b)      The Lessee will perform, comply with and observe (or
cause to be performed, complied with or observed) all obligations, covenants,
terms, conditions, indemnities and undertakings required under the Operative
Agreements, in accordance with the provisions thereof.
<PAGE>   6
                 SECTION 1.02  Guaranty Obligations.  As referenced herein, the
"Guaranteed Obligations" shall mean, collectively, the obligations described in
clauses (a) and (b) of Section 1.01.

Payments of Guaranteed Obligations shall be made (or grossed-up, as applicable)
free and clear of all Impositions in the manner set forth in Article VIII of
the Participation Agreement.

                 SECTION 1.03  Enforcement.  Regardless of whether the
Administrative Agent, Documentation Agent, Syndication Agent, Arranger or any
Lessor is (at any time) precluded or stayed from enforcing or exercising any of
its rights or remedies under the Operative Agreements against the Lessee, such
rights and remedies may be enforced directly against the Guarantor (as a
primary obligation of the Guarantor) without the joinder of, demand on or the
taking of any other Action against the Lessee or any other Person.  Regardless
of whether the Lessee is precluded or stayed from paying or performing (or
otherwise fails to pay or perform) any of the Guaranteed Obligations (upon
demand by the Administrative Agent), the Guarantor shall pay or perform (or
cause to be paid or performed) such Guaranteed Obligations.  Without limiting
the foregoing provisions of this Section 1.03, if enforcement of the rights or
remedies of the Administrative Agent, Documentation Agent, Syndication Agent,
Arranger or any Lessor under the Operative Agreements is dependent upon
delivering notices or taking any other Actions, then Administrative Agent,
Documentation Agent, Syndication Agent, Arranger or such Lessor may deliver
such notices to and take such other Actions with or against the Guarantor (in
lieu of the Lessee) for all purposes under this Guaranty and the other
Operative Agreements.  This Section 1.03 should not be construed to (i) impose
any conditions whatsoever on the obligations of the Guarantor under this
Guaranty or (ii) require the Administrative Agent, Documentation Agent,
Syndication Agent, Arranger or any Lessor to first exercise or exhaust remedies
against the Lessee or any other Person before exercising remedies against the
Guarantor pursuant to this Guaranty.


                                   ARTICLE II

                         REPRESENTATIONS AND WARRANTIES

                 To induce the Agents and the Lessors to enter into the
Participation Agreement and the Lease and to make the Fundings, the Guarantor
represents and warrants to the Lessors and the Agents as of the Documentation
Date and each Delivery Date as follows:

                 SECTION 2.01.  Organization and Qualification.  The Guarantor
and each Material Subsidiary (a) is a corporation or partnership duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation or organization, (b) has the corporate,
partnership or other power and authority to own its Equipment and to carry on
its business as now conducted and (c) is duly qualified as a foreign
corporation to do business and is in good standing in every jurisdiction in
which the failure to be so qualified would have a Material Adverse Effect.  As
of the Documentation Date, the corporations and other entities named in
Schedule 2.01 are all of the Material Subsidiaries of the Guarantor, such
Schedule (x) accurately reflects (i) the direct





                                       2
<PAGE>   7
owner of the Capital Stock of each such Subsidiary and (ii) the percentage of
the issued and outstanding Capital Stock of each such Subsidiary owned by the
Guarantor, and (y) accurately sets forth the jurisdictions of their respective
incorporation or organization and jurisdictions in which they are required to
be qualified as foreign corporations, foreign partnerships or other foreign
entities to do business.

                 SECTION 2.02.  Authorization, Validity, Etc.  The Guarantor
has the corporate power and authority to execute, deliver and perform its
obligations hereunder and under the other Operative Agreements to which it is a
party, and all such action has been duly authorized by all necessary corporate
proceedings on its part.  This Guaranty has been duly and validly executed and
delivered by the Guarantor and constitutes the valid and legally binding
agreement of the Guarantor enforceable against the Guarantor in accordance with
the terms hereof, and the other Operative Agreements to which the Guarantor is
a party, when duly executed and delivered by or on behalf of the Guarantor,
will constitute valid and legally binding obligations of the Guarantor
enforceable in accordance with the respective terms thereof, except, in each
case, (a) as such enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium, fraudulent transfer or other similar laws relating
to or affecting the enforcement of creditors' rights generally, and by general
principles of equity which may limit the right to obtain equitable remedies
(regardless of whether such enforceability is a proceeding in equity or at law)
and (b) as to the enforceability of provisions for indemnification for
violation of applicable securities laws, limitations thereon arising as a
matter of law or public policy.

                 SECTION 2.03.  Governmental Consents, Etc.  No authorization,
consent, approval, license or exemption of or filing or registration with any
Governmental Authority, is necessary for the valid execution, delivery or
performance by the Guarantor of any Operative Agreement to which it is a party,
except those that have been obtained.

                 SECTION 2.04.  Conflicting or Adverse Agreements or
Restrictions.  Neither the execution, delivery and performance by the Guarantor
of the Operative Agreements to which it is a party, nor compliance with the
terms and provisions thereof, nor the extension of the lease facility
contemplated by the Operative Agreements, (a) will breach or violate any
applicable Requirement of Law, (b) will result in any breach or violation of
any of the terms, covenants, conditions or provisions of, or constitute a
default under, or result in the creation or imposition of (or the obligation to
create or impose) any Lien upon any of its Equipment or assets pursuant to the
terms of any indenture, mortgage, deed of trust, agreement or other instrument
to which it or any of its consolidated Subsidiaries is party or by which any
Equipment or asset of it or any of its consolidated Subsidiaries is bound or to
which it is subject, except for breaches, violations and defaults under clauses
(a) and (b) that collectively will not have a Material Adverse Effect or (c)
will violate any provision of the certificate of incorporation or bylaws of the
Guarantor.

                 SECTION 2.05.  Title to Assets.  The Guarantor and each
consolidated Subsidiary has good and indefeasible title to its assets, except
for such defects in title as would not in the





                                       3
<PAGE>   8
aggregate have a Material Adverse Effect.  As of the Documentation Date, the
property of the Guarantor and the Subsidiaries is subject to no Liens, except
Permitted Liens and immaterial Liens.

                 SECTION 2.06.  Litigation.  Except for actions, suits or
proceedings described in the filings made by the Guarantor with the Securities
and Exchange Commission pursuant to the Exchange Act, as of the Documentation
Date and each Delivery Date, there are no actions, suits or proceedings pending
for which service of process has been accomplished or, to the best knowledge of
the Guarantor, threatened with respect to the Guarantor, the Operative
Agreements or any transactions contemplated therein that are reasonably likely
to have (individually or collectively) a Material Adverse Effect.

                 SECTION 2.07.  Information; Financial Statements.  All
information heretofore furnished by the Guarantor to the Agents or any Lessor
in connection with this Guaranty or any other Operative Agreement, as affected
by the disclosures made herein, in the other Operative Agreements and in the
filings made by the Guarantor with the Securities and Exchange Commission
pursuant to the Exchange Act, did not as of the date thereof and will not as of
the date of the Initial Delivery Date, when read together and taken as a whole,
contain any untrue statement of a material fact or omit to state a material
fact necessary in order to make the statements contained therein not misleading
in any material respect.  Since September 30, 1998 there has been no material
adverse change in the financial condition, business or operations of the
Guarantor and the Subsidiaries taken as a whole which could reasonably be
expected to have a Material Adverse Effect.

                 SECTION 2.08.  Investment Company Act.  Neither the Guarantor
nor any of the Subsidiaries is, or is regulated as, an "investment company," as
such term is defined in the Investment Company Act of 1940, as amended.

                 SECTION 2.09.  Public Utility Holding Company Act.  Neither
the Guarantor nor any of the Subsidiaries is a non-exempt "holding company," or
subject to regulation as such, or, to the knowledge of the Guarantor's
officers, an "affiliate" of a "holding company" or a "subsidiary company" of a
"holding company," within the meaning of the Public Utility Holding Company Act
of 1935, as amended.

                 SECTION 2.10.  ERISA.  (a) The Guarantor and each ERISA
Affiliate has maintained and administered each Plan in compliance with all
applicable laws except for such instances of noncompliance as have not resulted
in and would not reasonably be expected to have a Material Adverse Effect.
Neither the Guarantor nor any ERISA Affiliate has incurred any liability
pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of
the Code relating to employee benefit plans (as defined in Section 3 of ERISA),
and no event, transaction or condition has occurred or exists that would
reasonably be expected to result in the incurrence of any such liability by the
Guarantor or any ERISA Affiliate, or in the imposition of any Lien on any of
the rights, properties or assets of the Guarantor or any ERISA Affiliate
pursuant to Title I or IV of ERISA Sections 401(a)(29) or 412 of the Code,
other than such liabilities or Liens as would not in the aggregate reasonably
be expected to have a Material Adverse Effect.





                                       4
<PAGE>   9
                 (b)      No accumulated funding deficiency (as defined in
Section 412 of the Code or Section 302 of ERISA), in excess of $25,000,000,
whether or not waived, exists or is expected to be incurred with respect to any
Plan.

                 (c)      The Guarantor and its ERISA Affiliates have not
incurred withdrawal liabilities (and are not subject to contingent withdrawal
liabilities) under section 4201 or 4204 of ERISA in respect of Multiemployer
Plans that in the aggregate would reasonably be expected to have a Material
Adverse Effect.

                 (d)      All contributions have been timely made to all
employee benefit plans, as defined in Section 3 of ERISA, except for such
failures as would not reasonably be expected to have a Material Adverse Effect.

                 SECTION 2.11.  Tax Returns and Payments.  The Guarantor and
the Material Subsidiaries have caused to be filed all federal income tax
returns and other material tax returns, statements and reports (or obtained
extensions with respect thereto) which are required to be filed and have paid
or deposited or made adequate provision in accordance with GAAP for the payment
of all taxes (including estimated taxes shown on such returns, statements and
reports) which are shown to be due pursuant to such returns, except where the
failure to pay such taxes (collectively for the Guarantor and the Material
Subsidiaries) would not have a Material Adverse Effect.  No material income tax
liability of the Guarantor or the Material Subsidiaries has been asserted by
the Internal Revenue Service of the United States or any other Governmental
Authority for any taxes in excess of those already paid, except for taxes which
are being contested in good faith by appropriate proceedings and for which
adequate reserves in accordance with GAAP have been created on the books of the
Guarantor and the Subsidiaries.

                 SECTION 2.12.  Requirements of Law; Environmental Matters.
(a) The Guarantor and each consolidated Subsidiary is in compliance with all
Requirements of Law, applicable statutes, regulations and orders of, and all
applicable restrictions imposed by, all Governmental Authorities in respect of
the conduct of its business and the ownership of its Equipment, except for such
noncompliances which, in the aggregate for the Guarantor and all such
consolidated Subsidiaries, would not have a Material Adverse Effect.

                 (b)      The Guarantor monitors, in the ordinary course of its
business, the effect of existing Environmental Laws, and each claim asserted
against it or any Subsidiary by any Governmental Authority alleging potential
liability or responsibility for violation of any Environmental Law, on its
business operations and properties.  As a result thereof, the Guarantor has
reasonably concluded that such Environmental Laws and any such claims would
not, in the aggregate, for the Guarantor and its consolidated Subsidiaries have
a Material Adverse Effect.

                 SECTION 2.13.  Purpose of Advances.  (a) All proceeds of the
Advances will be used by Lessee for the purposes set forth in Section 2.2 of
the Participation Agreement.





                                       5
<PAGE>   10
                 (b)      None of the proceeds of the Advances will be used
directly or indirectly for the purpose of buying or carrying any "margin stock"
within the meaning of Regulation G or Regulation U (herein called "margin
stock") or for the purpose of reducing or retiring any indebtedness which was
originally incurred to buy or carry a margin stock, or for any other purpose
which might constitute this transaction a "purpose" credit within the meaning
of Regulation G or Regulation U.  Neither the Guarantor nor any agent acting on
its behalf has taken or will take any action which might cause this Guaranty or
any other Operative Agreement to violate Regulation G, T, U or X, or any other
regulation of the Board or to violate the Exchange Act.  Margin stock did not
on the Documentation Date, and does not constitute more than 25% of the assets
of the Guarantor or Lessee.

                 SECTION 2.14.  Designation of this Guaranty and the Guaranteed
Obligations.  This Guaranty and the Guaranteed Obligations hereunder constitute
"Designated Senior Indebtedness" as such phrase is used in the Debenture
Indenture.

                 SECTION 2.15.  Year 2000 Compliance.  The Guarantor has
developed a plan to ensure that the systems of the Guarantor and its Material
Subsidiaries are compliant in all material respects with the requirements to
process transactions in the year 2000.  The Guarantor and its Material
Subsidiaries plan to achieve year 2000 compliance through a combination of
upgrading to new releases of existing software and replacement of existing
software with new fully compliant systems by mid-1999.  The expenses and
capital expenditures of the Guarantor and its Material Subsidiaries associated
with achieving year 2000 compliance would not reasonably be expected to have a
Material Adverse Effect.  The Guarantor and its Material Subsidiaries are
currently gathering information from their key suppliers, vendors and financial
institutions regarding year 2000 compliance.


                                  ARTICLE III

                             AFFIRMATIVE COVENANTS

proxy statements so mailed and copies of all press releases.

after any Responsible Officer of the Guarantor obtains knowledge of

                          (i)     any event or condition which would reasonably
         be expected to have a Material Adverse Effect; or

                          (ii)    any event or condition which constitutes an
         Incipient Default or an Event of Default; or

                          (iii)   the occurrence of a Change of Control or
         Change of Control Event;

                 (f)      At the time of the delivery of the financial
statements provided for (i) in Sections 3.01(a) and (b), a certificate of a
Responsible Officer of the Guarantor in the form of Exhibit 3.01 to the effect
that no Incipient Default or Event of Default exists or, if any Incipient
Default or Event of Default does exist, specifying the nature and extent
thereof, which certificate shall also set forth calculations required to
establish whether the Guarantor was in compliance with the provisions of
Article VIII as at the end of such fiscal quarter or fiscal year, as the case
may be and (ii) in Section 3.01(b), to the extent there has been any change in
the information previously furnished to the Agents and the Lessors on Schedule
2.01, a revised Schedule 2.01.

                 (g)      Intentionally omitted.

                 (h)      Promptly, and in any event within 30 days after any
Responsible Officer of the Guarantor obtains knowledge thereof, notice:

                          (i)     of the occurrence or expected occurrence of
         any material Reportable Event with respect to any Plan, a failure to
         make any material required contribution to a Plan, any Lien in favor
         of the PBGC or a Plan, or any withdrawal from, or the termination,





                                       7
<PAGE>   12
         reorganization or insolvency (within the meaning of such terms as used
         in ERISA) of any Multiemployer Plan, or

                          (ii)    of the institution of proceedings or the
         taking of any other action by the PBGC or the Guarantor or any ERISA
         Affiliate or any Multiemployer Plan with respect to the withdrawal
         from, or the terminating, reorganization or insolvency (within the
         meaning of such terms as used in ERISA) of, any Plan which
         termination, reorganization or insolvency would reasonably be expected
         to have a Material Adverse Effect, except that no notice shall be
         required with respect to the merger of a defined contribution plan of
         one ERISA Affiliate into a defined contribution plan of another ERISA
         Affiliate.

                 (i)      From time to time and with reasonable promptness,
such other information or documents (financial or otherwise) with respect to
the Guarantor or any Subsidiary as either Agent or any Lessor through the
applicable Agent may reasonably request.

                 SECTION 3.02.  Books, Records and Inspections.  The Guarantor
will permit, or cause to be permitted, any Lessor, upon written notice, to
visit and inspect any of the properties of the Guarantor and the Subsidiaries,
to examine the corporate books and financial records of the Guarantor and the
Subsidiaries and to discuss the affairs, finances and accounts of any such
corporations with a Responsible Officer of the Guarantor and such Subsidiaries,
all at such reasonable times and as often as such Lessor, through the
Administrative Agent, may reasonably request.

                 SECTION 3.03.  Insurance and Maintenance of Properties.  The
Guarantor will maintain or cause to be maintained, with financially sound and
reputable insurers, insurance with respect to its Equipment and business
against such liabilities, casualties, risks and contingencies (including
business interruption insurance) and in such types and amounts as is customary
in the case of Persons engaged in the same or similar businesses and similarly
situated.

                 SECTION 3.04.  Payment of Taxes and other Claims. The
Guarantor will, and will cause each of the Material Subsidiaries to, pay or
discharge or cause to be paid or discharged, before the same shall become
delinquent, all taxes, assessments and governmental charges levied or imposed
upon the Guarantor or such Material Subsidiary or upon the income, profits or
Equipment of the Guarantor or such Material Subsidiary except for (i) such
taxes, assessments as would not, individually or in the aggregate, have a

created thereunder, a written notice signed by a Responsible Officer of the
Guarantor or the applicable ERISA Affiliate specifying the nature thereof, what
action the Guarantor or the applicable ERISA Affiliate is taking or proposes to
take with respect thereto, and, when known, any action taken by the PBGC, the

Guarantor covenants that it shall and shall cause each ERISA Affiliate to
comply, with respect to each Plan and Multiemployer Plan, with all applicable

such disposition, (ii) the aggregate sales price from such disposition shall be
paid in cash or otherwise on payment terms satisfactory to the Guarantor or
Subsidiary, and (iii) the aggregate book value of all assets of the Guarantor

transactions with any Person who is not either (i) a Borrower or one of the
Guarantor's consolidated Subsidiaries or (ii) Weatherford\Al-Rushaid Limited or
Weatherford Saudi Arabia Limited, on terms that are less favorable to the
Guarantor or such consolidated Subsidiary, as the case may be, than would be

foregoing, the restrictions set forth in this covenant will not apply to (i)
the payment of reasonable and customary regular fees to directors of the
Guarantor who are not employees of the Guarantor; (ii) loans and advances to

be adverse to the Lessors.

obligations hereunder) based upon any claim that the Guarantor, or any other
Person, may have against the Lessee or any other Person, and shall remain in

with, hinder or prevent, or in any way adversely affect, the performance by the
Guarantor, the Lessee or any of their Subsidiaries under the Operative
Agreements or any assignments thereof;

                 (l)      any action or inaction or election of remedies by the
Administrative Agent or the Lessor or any other Person, including any failure
by the Administrative Agent or any Lessor or any other Person to protect,
secure, perfect or insure any Lien at any time held by it as security for the
Guaranteed Obligations or for this or any Guaranty Equipment subject thereto;

                 (m)      any release, discharge or rejection of the Lessee or

under any Bankruptcy Law or as a result of any bankruptcy or reorganization
case in which the Guarantor or the Lessee is a debtor);

                 (n)      any other occurrence or circumstance whatsoever,
whether similar or dissimilar to the foregoing and any other circumstances that
might otherwise constitute a legal or equitable defense or discharge of a
guarantor, indemnitor or surety or that might otherwise limit recourse against
the Guarantor;

                 (o)      any change in circumstances, whether or not foreseen
or foreseeable, whether or not imputable to the Guarantor, the Administrative
Agent or any Lessor or any other Person and whether or not such change in
circumstances shall or might in any manner and to any extent vary the risk of
the Guarantor hereunder; or

                 (p)      any other circumstance whatsoever (with or without
notice to or knowledge of the Guarantor, the Lessee or any of their
Subsidiaries) which constitutes, or might be construed to constitute, an
equitable or legal discharge of any of their obligations under the Operative
Agreements, in bankruptcy or in any other instance.

The obligations of the Guarantor set forth in this Agreement constitute the
full recourse obligations of the Guarantor enforceable against it to the full
extent of all its assets and properties, notwithstanding any provisions in any
agreements from time to time relating to the acquisition, financing and
refinancing by the Administrative Agent or Lessors of their interest in the
Equipment which may limit the liability of the Administrative Agent or Lessors
or any other Person pursuant to such agreements.


                                  ARTICLE VII

                                   BANKRUPTCY

                 SECTION 7.01  No Subrogation.  THE GUARANTOR HEREBY WAIVES,
UNTIL SUCH TIME AS, INDEFEASIBLE PAYMENT IN FULL OF THE GUARANTEED OBLIGATIONS
HAS BEEN MADE, ANY AND ALL RIGHTS OF SUBROGATION, INDEMNITY, CONTRIBUTION OR
REIMBURSEMENT, ANY BENEFIT OF, OR RIGHT TO ENFORCE ANY REMEDY THAT THE
ADMINISTRATIVE AGENT OR ANY LESSOR OR OTHER PERSON NOW HAS OR MAY HEREAFTER
HAVE AGAINST THE LESSEE IN RESPECT OF THE GUARANTEED OBLIGATIONS, OR ANY
EQUIPMENT, NOW OR HEREAFTER HELD BY THE ADMINISTRATIVE AGENT OR ANY LESSOR AS
SECURITY FOR THE GUARANTEED OBLIGATIONS AND ANY AND ALL SIMILAR RIGHTS THE
GUARANTOR MAY HAVE AGAINST THE LESSEE UNDER APPLICABLE LAW OR OTHERWISE.  If,
notwithstanding the foregoing, any amount shall be paid to Guarantor on account
of any such subrogation, indemnity, contribution or reimbursement rights at any
time, such amount shall, if paid prior to such indefeasible payment in full of
the Guaranteed Obligations, be held in trust for the benefit of the Lessors and
the Administrative Agent, and shall forthwith be paid to the Administrative
Agent to be credited and applied against the Guaranteed Obligations, whether
matured, unmatured, absolute or contingent, as the Lessors and the
Administrative Agent may see fit in their discretion.

                 SECTION 7.02  Reinstatement.  Notwithstanding anything to the
contrary herein contained, this Agreement, and all obligations of the Guarantor
hereunder, shall continue to be effective or be reinstated, as applicable, if
at any time, payment, or any part thereof, of any or all obligations performed
by the Guarantor, the Lessee or any of their Subsidiaries are rescinded,
invalidated, or otherwise required to be restored or returned by the
Administrative Agent or any Lessor pursuant to any Bankruptcy Law or upon the
insolvency, bankruptcy or reorganization of the Guarantor, the Lessee or any of
their Subsidiaries (or otherwise) all as though such payment or application of
proceeds had not been made.  Without limiting the generality of the foregoing,
if, prior to any such rescission, invalidation, declaration, restoration or
return, this Guaranty or any other Operative Agreement shall have been canceled
or surrendered, this Guaranty and the Guaranteed Obligations shall be
reinstated in full force and effect, and such prior cancellation or surrender
shall not diminish, release, discharge, impair or otherwise affect the
obligations of the Guarantor in respect of the amount of the affected payment
or application of proceeds (or any Lien or collateral securing such
obligation).

                 SECTION 7.03  Non-Discharged Obligations.  Notwithstanding (a)
any modification, discharge or extension of the obligations of the Guarantor
hereunder or the obligations of the Lessee under the Operative Agreements, (b)
any disallowance of all or any portion of the Administrative Agent's or any
Lessor's or other Person's claim for repayment or performance of such
obligations, (c) any use of cash or other collateral pursuant to any Bankruptcy
Law or in any bankruptcy or reorganization case, (d) any agreement or
stipulation as to adequate protection pursuant to any Bankruptcy Law or in any
bankruptcy or reorganization case, (e) any failure by the Administrative Agent
or any Lessor or other Person to file or enforce a claim against the Guarantor
or the Lessee pursuant to any Bankruptcy Law or in any bankruptcy or
reorganization case, or (f) any release, discharge, rejection, amendment,
modification, stay or cure of the Administrative Agent's, the Lessee's,
Guarantor's or any Lessor's or other Person's rights or obligations that may
occur pursuant to any Bankruptcy Law or in any bankruptcy or reorganization
case or proceeding affecting the Guarantor or the Lessee, whether permanent or
temporary, and whether assented to by any Lessor, the Administrative Agent or
any other Person, the Guarantor hereby agrees that the Guarantor shall be
obligated to perform hereunder.

                                 MISCELLANEOUS

                 SECTION 8.01  Notices.  All notices, consents, offers,
directions, approvals, instructions, requests, and other communications given
to any Person pursuant to this Guaranty shall be in writing and be given in the
manner and at the appropriate address set forth in the Participation Agreement
or at such other address as such party shall designate by notice to each of the
other parties to the Operative Agreements.

                 SECTION 8.02  Representations.  The Guarantor represents and
warrants that it is not entitled to immunity from judicial proceedings in a
court of competent jurisdiction located in the United States and agrees that,
should the Administrative Agent or other Person bring any judicial proceedings,
to enforce the liability of the Guarantor under this Guaranty, no immunity from
such proceedings will be claimed by or on behalf of Guarantor or with respect
to the Guarantor's property.  Nothing in this Section 8.02 shall affect the
right of the Administrative Agent or any other Person to serve process in any
manner permitted by Law or to commence legal proceedings, or otherwise proceed
against the Guarantor in any court in which the Guarantor is subject to suit.

                 SECTION 8.03  Non-Exclusive Remedies.  No right or remedy of
the Administrative Agent or any Lessor or other Person under any Operative
Agreement shall be exclusive of any other right, power or remedy, but shall be
cumulative and in addition to any other right, power or remedy thereunder or
now or hereafter existing by Law or in equity and the exercise by the
Administrative

Agent or any Lessor or other Person of any one or more of such rights, powers
or remedies shall not preclude the simultaneous or further exercise of any or
all of such other rights, powers or remedies.  Any failure to insist upon the
strict performance of any provision hereof or to exercise any option, right,
power or remedy contained herein shall not constitute a waiver or
relinquishment thereof for the future.  Receipt by the Administrative Agent or
any Lessor or other Person of any amount payable under any Operative Agreement
with knowledge of a Default or Event of Default shall not constitute a waiver
of such Default or Event of Default, and no waiver by the Administrative Agent
or any Lessor or other Person of any provision of the Operative Agreements
shall be deemed to be made unless made in writing.

                 SECTION 8.04  Amendments and Waivers.  All amendments, waivers,
consents, or approvals arising pursuant to this Guaranty shall be consummated
in accordance with Article X of the Participation Agreement.  No waiver by any
Lessor or the Administrative Agent of any Default or Event of Default shall in
any way be, or be construed to be, a waiver of any further or subsequent
Default or Event of Default.

                 SECTION 8.05  Severability.  If any provision of this Guaranty
or the application thereof to any Person or circumstance shall be invalid or
unenforceable, then the remaining provisions, or the application of such
provision to Persons or circumstances other than those as to which it is
invalid or enforceable, shall continue to be valid and enforceable.

                 SECTION 8.06  Further Assurances.  The Guarantor hereby agrees
to execute and deliver all such instruments and take all such action as the
Lessors may from time to time reasonably request in order to effectuate fully
the purposes of this Guaranty.

                 SECTION 8.07  Governing Law and Submission to Jurisdiction.

                 (a)      THIS GUARANTY SHALL BE GOVERNED BY AND INTERPRETED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE
CONFLICT-OF-LAWS PROVISIONS THEREOF.

                 (b)      ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO ANY
OPERATIVE AGREEMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF
THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, AND, BY
EXECUTION AND DELIVERY OF THIS GUARANTY, THE GUARANTOR HEREBY ACCEPTS FOR
ITSELF AND IN RESPECT OF ITS EQUIPMENT, GENERALLY AND UNCONDITIONALLY, THE
JURISDICTION OF THE AFORESAID COURTS.  THE GUARANTOR HEREBY IRREVOCABLY WAIVES
ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE
GROUNDS OF FORUM NON CONVENIENS.  WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS.
THIS SUBMISSION TO JURISDICTION IS NONEXCLUSIVE AND DOES NOT PRECLUDE THE
ADMINISTRATIVE AGENT OR THE LESSORS FROM OBTAINING JURISDICTION OVER THE
GUARANTOR IN ANY COURT OTHERWISE HAVING JURISDICTION.

IRREVOCABLY AND UNCONDITIONALLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW,
TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO ANY OPERATIVE

Weatherford International, Inc.
5 Post Oak Park, Suite 1760
Houston, Texas  77027-3415

Ladies and Gentlemen:

         We have acted as counsel for Weatherford International, Inc., a
Delaware corporation (the "Company"), in connection with the filing by it of a
Registration Statement on Form S-4 (the "Registration Statement") with the
Securities and Exchange Commission for registration under the Securities Act of
1933, as amended, of up to 5,052,000 shares (the "Shares") of the Company's
common stock, $1.00 par value. The Shares are to be issued in connection with a
proposed merger (the "Merger") of Christiana Acquisition, Inc., a Wisconsin
corporation and wholly owned subsidiary of the Company ("Sub"), with and into
Christiana Companies, Inc., a Wisconsin corporation ("Christiana"), pursuant to
an Amended and Restated Agreement and Plan of Merger dated October 14, 1998 (the
"Merger Agreement"), by and among the Company, Sub, Christiana and C2, Inc., a
Wisconsin corporation.

         In connection with the foregoing, we have examined originals or copies
certified or otherwise identified to our satisfaction of the Registration
Statement, the Merger Agreement, the Amended and Restated Certificate of
Incorporation of the Company, as amended, the Amended and Restated By-laws of
the Company, the corporate proceedings with respect to the Merger and the
proposed issuance of the Shares and such other documents and instruments as we
have deemed necessary or appropriate for the expression of the opinions
contained herein.

         We have assumed the authenticity and completeness of all records,
certificates and other instruments submitted to us as originals, the conformity
to original documents of all records, certificates and other instruments
submitted to us as copies, the authenticity and completeness of the originals of
those records, certificates and other instruments submitted to us as copies and
the correctness of all statements of fact contained in all records, certificates
and other instruments that we have examined.

         Based on the foregoing, and having regard for such legal considerations
as we have deemed relevant, we are of the opinion that the Shares to be issued
by the Company in connection with the Merger have been duly authorized for
issuance and, assuming the Merger is approved by the

stockholders of the Company and the shareholders of Christiana and the Merger is
effected, the Shares, when issued in accordance with the terms and conditions of
the Merger Agreement, will be validly issued, fully paid and nonassessable.

         The foregoing opinion is limited to the federal laws of the United
States of America and the General Corporation Law of the State of Delaware, and
we are expressing no opinion as to the effect of the laws of any other
jurisdiction.

Re:    Merger of Christiana Companies, Inc. and Christiana Acquisition, Inc., a
       newly formed subsidiary of Weatherford International, Inc.

Gentlemen:

You have requested our opinion regarding certain federal income tax
consequences of the acquisition of all of the outstanding shares of Christiana
Companies, Inc. ("Christiana") common stock by Weatherford International, Inc.
("Weatherford") in a transaction in which Christiana Acquisition, Inc. ("Sub"),
a newly formed Wisconsin subsidiary of Weatherford, will be merged ("the
Merger") with and into Christiana, and as a result thereof the holders of
Christiana common stock will receive shares of Weatherford voting common stock
and cash. This opinion is effective as of the day and time of the closing of
the Merger.

In rendering our opinion, we have relied upon the accuracy and completeness of
the facts, assumptions and representations (without regard to any limitation
based on knowledge or belief):

(i)      set forth herein
(ii)     contained in the documents listed on Exhibit A to this opinion, and
(iii)    set forth in the representation letters signed by appropriate
         officers of Christiana, Weatherford and Sub (attached as Exhibit B)
         to be effective as of the day and time of the closing of the Merger.

Christiana, Weatherford and Sub have represented that such facts, assumptions
and representations are true, correct and complete. However, we have not
independently audited or otherwise verified any of these facts, assumptions or
other representations. A misstatement or omission of any fact or a change or
amendment in any of the facts, assumptions or representations we have relied
upon may require a modification of all or a part of this opinion. In addition,
our opinion is based on the facts as represented to us as of the date of this
letter. Any changes in the facts or form of the transactions between the date
of this letter and the actual closing of the transactions may require a
modification of all or part of this opinion. We

have no responsibility to update this opinion for events, transactions, 
circumstances or changes in any of the facts, assumptions or representations 
occurring after this date.

Premise of Opinion

Our opinion is expressed only with respect to what we considered to be the
material federal income tax consequences of the Merger under the conditions
described herein. The opinion expressed herein is based upon our interpretation
of the Internal Revenue Code of 1986, as amended (the "Code"), income tax
regulations thereunder, court decisions, rulings and procedures issued by the
Internal Revenue Service (the "Service") and other authorities that we deemed
relevant, in each case as of the date of this letter. Should there be any
change, including any change having retroactive effect, in any of such
authorities, the opinion expressed herein would necessarily have to be
reevaluated in light of such change. The Service has indicated that regulations
will be issued for certain "inversion" transactions, occurring after September
21, 1994, which depending on the scope and content of those regulations, could
require Christiana and/or its shareholders to recognize gain or income as a
result of the Merger (see Notice 94-93, 1994-2 C.B. 563). We have no
responsibility to update our opinion for changes in applicable law or other
authorities occurring after the effective date of this letter.

We have not considered any non-income tax consequences, or any state, local,
foreign, or other income tax (other than federal income tax) consequences, and
therefore we express no opinion regarding the treatment that would be accorded
the Merger for such purposes. We also express no opinion on non-tax issues,
such as corporate law or securities law matters. The opinion does not address
the tax consequences of the Merger to a Christiana shareholder that has a
special status, including insurance companies; tax-exempt entities; financial
institutions or broker-dealers; foreign corporations; estates and trusts not
subject to U.S. federal income tax on their income regardless of source;
persons who are not citizens or residents of the United States; and persons who
acquired their Christiana common stock as a result of the exercise of an
employee stock option, pursuant to an employee stock purchase plan, or
otherwise as compensation.

Further, our opinion does not address the potential tax ramifications to
Christiana, Weatherford and their affiliates or shareholders of any transaction
other than the Merger.

This opinion is not binding on the Service, and there can be no assurance that
the Service will not take positions contrary to the opinion expressed herein.

Certain Federal Income Tax Consequences of the Merger                   

Our opinion is limited to the federal income tax consequences of the Merger
that we believe are material to Christiana, the Christiana common shareholders,
Sub and Weatherford. In our opinion:

<PAGE>   3
Board of Directors
Page 3
December 23, 1998




1.  The Merger of Sub with and into Christiana, with Christiana being the
    surviving corporation in the Merger, will constitute a reorganization
    pursuant to Code ss.368(a)(1)(A) and Code ss.368(a)(2)(E).

2.  Under Code ss.368(b), Christiana, Weatherford and Sub will be parties to the
    reorganization.

3.  Neither Weatherford nor Sub will recognize any gain or loss as a result of
    the Merger. Code ss.354(a)(1).

4.  No gain or loss will be recognized by Christiana on the consummation of the
    Merger.

5.  The holders of Christiana common stock will recognize no gain or loss as a 
    result of the receipt of Weatherford voting common stock in exchange for
    their Christiana common stock in the Merger pursuant to Code
    ss.354(a)(1). The holders of Christiana common stock will recognize gain
    to the extent of the cash received in exchange for the Christiana common
    stock. Provided that such gain is properly characterized as gain from a
    sale or exchange and not as a dividend, the gain recognized will not
    exceed the gain realized on the transaction. Codess.354(a)(1) and
    Codess.356(a)(1). The gain recognized by the holders of Christiana common
    stock, as determined under Codess.356(a)(1), will be capital gain
    provided the Christiana stock exchanged would constitute a capital asset
    in the hands of the exchanging shareholder and the hypothetical
    redemption of stock is not essentially equivalent to a dividend.
    Codess.302(b)(1) and Commissioner v. Clark, 489 U.S. 726 (1989).

6.  Under Code ss.358(a)(1), the tax basis of the shares of the Weatherford
    voting common stock received by the Christiana shareholders in the Merger
    will be the same as the basis of the shares of Christiana common stock
    surrendered in exchange therefor, decreased by the amount of cash received
    by the holder of Christiana stock, and increased by gain recognized in the
    transaction.

7.  Under Code ss.1223(1), the holding period of the Weatherford voting common
    stock received by each holder of Christiana common stock will include the
    holding period of the Christiana common stock held by such holder,
    provided that such Christiana stock is a capital asset in the hands of
    such holder on the date of the Merger.

This opinion is solely for the benefit of Christiana, the Christiana
shareholders, Sub and Weatherford and is not intended to be relied upon by any
other party. Except to the extent expressly permitted hereby, and without the
prior written consent of this firm, this letter may not be quoted in whole or
in part, or otherwise referred to in any documents or delivered to any person
or entity. Any such authorized other party receiving a copy of this letter must
consult and rely upon the advice of their own counsel, accountant or other
advisor.

TO: FIRSTAR BANK MILWAUKEE, N.A.
 
   
     1. Christiana Common Stock. In accordance with the Amended and Restated
Agreement and Plan of Merger dated as of October 14, 1998 (the "Agreement"),
relating to the merger (the "Merger") of Christiana Acquisition, Inc., a wholly
owned subsidiary of Weatherford with and into Christiana and pursuant to which
each shareholder of Christiana will receive shares of common stock of
Weatherford and cash consideration of between $3.50 and $4.00 per share (the
"Cash Consideration"), the undersigned hereby submits the certificate(s) listed
below representing shares of common stock, $1.00 par value, of Christiana
("Christiana Common Stock"). The enclosed certificate(s) formerly represented
shares of Christiana Common Stock and are to be exchanged for .85191 of one
share of common stock, $1.00 par value, of Weatherford ("Weatherford Common
Stock") and the Cash Consideration (subject to the undersigned's election to
acquire common stock, $0.01 par value, of C2 ("C2 Common Stock") as provided for
below).
    
 
   
     The Agreement provides that if the market price of Weatherford Common Stock
is less than $18.30 per share following the Special Meeting of Christiana
Shareholders, then Christiana will use up to an additional $5.0 million of its
cash to purchase additional shares of Weatherford Common Stock to qualify the
Merger as a partially tax free reorganization (the "Additional Purchases").
    
 
   
     If Christiana purchases additional shares of Weatherford Common Stock, the
Cash Consideration to be paid in the Merger could decline by up to $5.0 million,
or approximately $1.00 per share of Christiana Common Stock (from between $3.50
and $4.00 per share to between $2.50 and $3.00 per share). Weatherford and
Christiana will not know whether this reduction will occur, and if so to what
extent, until after the Special Meeting of Christiana Shareholders.
    
 
     All fractional shares that a holder of Christiana Common Stock would
otherwise be entitled to receive shall be aggregated and if a fractional share
of Weatherford Common Stock results from such aggregation, such fractional share
shall be rounded up or down to the nearest whole share of Weatherford Common
Stock.

     2. C2 Stock. The undersigned hereby makes the following election regarding
the purchase of C2 Stock:
 
   
                   ELECTION TO PURCHASE C2, INC. COMMON STOCK
    
 
   
     I understand (i) that I will receive between approximately $3.50 and $4.00
for each share of Christiana Common Stock that I own immediately prior to the
Merger, unless Christiana makes the Additional Purchases, in which case I will
receive between $2.50 and $3.00 per share of Christiana Common Stock; (ii) that
I am entitled to purchase one share of C2 Common Stock at $4.00 per share for
each share of Christiana Common Stock that I own immediately prior to the
Merger; and (iii) that I may purchase more shares of C2, if they are available.
    
 
   
     I FURTHER UNDERSTAND THAT BECAUSE THE CASH CONSIDERATION MAY BE LESS THAN
$4.00 PER SHARE OF CHRISTIANA COMMON STOCK, MY ELECTION BELOW MAY RESULT IN THE
NEED FOR ADDITIONAL CASH TO EFFECT MY PURCHASE OF C2 COMMON STOCK. IN THE EVENT
THAT ADDITIONAL CASH IS NEEDED, I AUTHORIZE YOU TO SEND ME AN INVOICE FOR THE

RECEIPT.

     3. [ ] I want to use the cash (between approximately $3.50 and $4.00 per

            as many shares of C2 as possible with such cash.
    
 
   
     4. [ ] I only want to purchase           shares of C2 Common Stock using a
            portion of the cash (between approximately $3.50 and $4.00 per
            share, assuming no Additional Purchases) to which I am entitled from
            the sale of my Christiana Common Stock pursuant to the Merger
            Agreement. Please apply the appropriate amount to such purchase and
            send me the balance, if any.
    
 
   
     5. [ ] I only want to purchase the number of shares of C2 Common Stock to

            wish to purchase an additional           shares of C2 (if they are
            available). Accordingly, I am enclosing the amount set forth below
            payable to Firstar Bank Milwaukee, N.A.:
    
 
Number of additional C2 shares I want to buy           times $4.00 per share:

Firstar Bank Milwaukee, N.A. that the undersigned has full power and authority
to assign and transfer the shares of Christiana Common Stock made subject to

PART III  CERTIFICATION

  Under penalties of perjury, I certify that:
 
  1. The number shown on this form is my correct taxpayer identification number
     (or I am waiting for a number to be issued to me), and
 
  2. I am not subject to backup withholding because: (a) I am exempt from backup
     withholding, or (b) I have not been notified by the Internal Revenue
     Service (IRS) that I am subject to backup withholding as a result of a
     failure to report all interest or dividends, or (c) the IRS has notified me
     that I am no longer subject to backup withholding.

  debt, contributions to an individual retirement arrangement (IRA), and
  generally, payments other than interest and dividends, you are not required to
  sign the Certification, but you must provide your correct TIN.

                                  INSTRUCTIONS
 
   
     1. TIME IN WHICH TO ELECT. This form or a facsimile thereof should be
submitted, accompanied by the certificates representing shares of Christiana
Common Stock described on the front hereof (unless the certificates were
previously delivered in connection with the Special Meeting on August 17, 1998
and are still held by Firstar Bank Milwaukee, N.A.), to Firstar Bank Milwaukee,
N.A. at the appropriate address set forth on the front hereof, no later than
5:00 P.M., Central Time, on             , 1999. Holders of Christiana Common
Stock whose Form Letters of Transmittal and certificates are not so delivered
will not be entitled to make an Election to purchase shares of C2 Common Stock,
but will be entitled to receive the consideration provided for Christiana
shareholders in the Merger.
    
 
   
     2. CHANGE OR REVOCATION OF LETTER OF TRANSMITTAL. Any record holder of
Christiana Common Stock may change an Election by delivering a written notice
accompanied by a properly completed, revised Form Letter of Transmittal to
Firstar Bank Milwaukee, N.A. prior to 5:00 P.M., Central Standard Time, on
     --     , 1999. Similarly, an Election may be revoked by delivering a
written notice to Firstar Bank Milwaukee, N.A. prior to such time or by
withdrawing prior to such time the certificates previously deposited with
Firstar Bank Milwaukee, N.A.
    
 
     3. NULLIFICATION OF ELECTION. All Form Letters of Transmittal will be void
and deemed to be of no effect if the Merger is not consummated, and certificates
submitted therewith shall be returned to the persons submitting the same as
promptly as practicable. The undersigned directs Firstar Bank Milwaukee, N.A. to
issue in exchange for the Christiana Common Stock subject hereto the
certificates representing the Weatherford Common Stock and a check for the Cash
Consideration into which such Weatherford Common Stock will be converted in the
Merger in the name(s) of the registered owner(s) of the shares of Christiana
Common Stock subject hereto, unless otherwise indicated under the "Election to
Purchase C2, Inc. Shares" and/or "Special Issuance Instructions" boxes herein.
The undersigned directs Firstar Bank Milwaukee, N.A., unless otherwise indicated
under the "Election to Purchase C2, Inc. Shares" and/or "Special Delivery
Instructions" boxes herein, to mail such certificates and check to the
undersigned at the address shown above.
 
   
     4. RECEIPT OF CHECKS AND WEATHERFORD COMMON STOCK. As soon as possible
after the date of the Merger, but no later than 30 days thereafter (the "Payment
Date"), the parties to the Merger Agreement shall calculate and agree upon the
Cash Consideration (anticipated to be between approximately $3.50 and $4.00 per
share of Christiana Common Stock assuming no Additional Purchases based upon the
terms of the Merger Agreement as described more fully on the cover page of the
Joint Proxy Statement/Prospectus). On the Payment Date, Weatherford will pay the
Cash Consideration due each Christiana Shareholder to Firstar Bank Milwaukee,
N.A. who shall promptly distribute such cash to each Christiana Shareholder;
provided, however, that if the Firstar Bank Milwaukee, N.A. has authorization
from the Christiana Shareholders pursuant to this Form to apply all or a portion
of the Cash Consideration to the purchase of shares of C2 Common Stock, such
cash shall be so applied. Firstar Bank Milwaukee, N.A. shall, following
instructions from the Christiana Shareholders, either transmit such funds to C2
to purchase shares of C2 Common Stock or transmit such funds to the Christiana
Shareholders.
    
 
     THE METHOD OF DELIVERY OF ALL DOCUMENTS IS AT THE OPTION AND RISK OF THE
SHAREHOLDER, BUT IF SENT BY MAIL, REGISTERED MAIL, PROPERLY INSURED, IS
SUGGESTED.
 
     5. INADEQUATE SPACE. If there is insufficient space to list all
certificates being submitted to Firstar Bank Milwaukee, N.A. or to respond to
any other information, please attach a separate sheet hereto.
 
     6. SIGNATURES. The signature (or signatures, in the case of certificates
owned by two or more joint holders) on the Form Letter of Transmittal should
correspond exactly with the name(s) as written on the face of the certificates
unless the shares of Christiana Common Stock described on the Form Letter of
Transmittal have been assigned by the registered holder(s), in which event the
Form Letter of Transmittal should be signed in exactly the same form as the name
of the last transferee endorsed on the certificates or on accompanying stock
powers. In addition, in the event of such assignment, the certificates must be
endorsed or
<PAGE>   7
 
accompanied by appropriate stock powers, signed exactly as the name(s) of the
registered owner(s) appear on the certificate and such signature(s) must be
GUARANTEED as provided in Instruction 8.
 
     IF THE FORM LETTER OF TRANSMITTAL IS SIGNED BY A TRUSTEE, EXECUTOR,
ADMINISTRATOR, GUARDIAN, OFFICER OF A CORPORATION, ATTORNEY-IN-FACT OR IN ANY
OTHER REPRESENTATIVE OR FIDUCIARY CAPACITY, THE PERSON SIGNING MUST GIVE SUCH
PERSON'S FULL TITLE IN SUCH CAPACITY, AND APPROPRIATE EVIDENCE OF AUTHORITY TO
ACT IN SUCH CAPACITY MUST BE FORWARDED WITH THE FORM LETTER OF TRANSMITTAL. FOR
A CORPORATION, APPROPRIATE EVIDENCE OF AUTHORITY OF AN OFFICER WOULD INCLUDE A
CERTIFIED BOARD RESOLUTION.
 
     If shares of Christiana Common Stock are registered in different names on
several certificates, it will be necessary to complete, sign and submit as many
separate Form Letters of Transmittal as there are different registrations of
certificates.
 
     7. CHECKS AND NEW CERTIFICATES IN SAME NAME. If checks or certificates
representing Weatherford Common Stock are to be payable to the order of or
registered in exactly the same name that appears on the certificates
representing shares of Christiana Common Stock being submitted herewith, the
shareholder will not be required to endorse the old certificates or to make
payment of transfer taxes.
 
     8. CHECKS AND NEW CERTIFICATES IN DIFFERENT NAMES. If checks or stock
certificates representing Weatherford Common Stock are to be payable to the
order of or registered in other than exactly the name that appears on the
certificates submitted herewith, the certificates submitted must be endorsed, or
accompanied by appropriate, signed stock powers, and the SIGNATURE GUARANTEED by
a member of a national securities exchange or of the National Association of
Securities Dealers, Inc. ("NASD") or by a commercial bank or trust company in
the United States. Additionally, in such case all requisite stock transfer tax
stamps must be affixed to the certificates submitted.
 
     9. LOST CERTIFICATES. If a holder is not able to locate his certificates
representing shares of Christiana Common Stock, he should contact Christiana for
advice on the procedure to be followed to obtain replacement certificates. Such
holder should note that it may take in excess of two weeks to obtain such
replacement certificates.
 
   
     10. NON-UNITED STATES RESIDENTS. Non-United States residents purchasing
shares of C2 Common Stock must verify by proper execution of the statement made
in the signature box entitled "To Be Executed Only By Non-United States
Residents".
    
 
     11. IMPORTANT TAX INFORMATION. Federal income tax law requires that each
holder of Christiana Common Stock certify to the Exchange Agent such holder's
correct Taxpayer Identification Number ("TIN") and to indicate that the holder
is not subject to backup withholding. If such holder is an individual, the TIN
is his or her social security number. Payments that are made to such holder with
respect to such Cash Consideration are subject to backup withholding if such
holder fails to make such certification on the enclosed Substitute Form W-9.
 
     If backup withholding applies, the Exchange Agent is required to withhold
31% on payments for Christiana Common Stock made to the holder pursuant to the
Merger. Backup withholding is not an additional tax. Rather, the tax liability
of persons subject to backup withholding will be reduced by the amount of tax
withheld. If backup withholding results in an overpayment of taxes, a refund may
be obtained from the Internal Revenue Service. Certain holders (including, among
others, all corporations and certain foreign individuals) are exempt from the
backup withholding and reporting requirements. In order for a holder who is a
foreign individual to qualify as an exempt recipient, such holder must submit a
statement on the appropriate form, signed under penalties of perjury, attesting
to that individual's exempt status. Such statements can be obtained from the
Exchange Agent.
 
     If the holder has not been issued a TIN or intends to apply for a TIN in
the near future, the holder should write "Applied For" in the space for the TIN.
If the Exchange Agent is not provided with a TIN before the effective time of
the Merger, the Exchange Agent will withhold 31% on all payments for any
Christiana Common Stock made to the holder pursuant to the Merger.
 
     12. MISCELLANEOUS. A single check or a single stock certificate will be
issued for all shares subject to each Form Letter of Transmittal unless written
instructions to the contrary are attached hereto.

     All questions with respect to this Form Letter of Transmittal, these
Instructions and the Election (including, without limitation, questions relating
to the timeliness or effectiveness of revocation of any Election and
computations as to proration) will be determined by Firstar Bank Milwaukee, N.A.
in accordance with the terms of the Merger Agreement and C2 Prospectus.
