F-13 3 REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To the Administrative Committee of the Weatherford Enterra, Inc. 401(k) Savings Plan: We have audited the accompanying statements of net assets available for plan benefits of the Weatherford Enterra, Inc. 401(k) Savings Plan (the Plan) as of December 31, 1997 and 1996, and the related statement of changes in net assets available for plan benefits for the year ended December 31, 1997. These financial statements and supplemental schedules referred to below are the responsibility of the Administrative Committee. Our responsibility is to express an opinion on these financial statements and supplemental schedules 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 the Administrative Committee, 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 financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits of the Plan as of December 31, 1997 and 1996, and the changes in net assets available for plan benefits for the year ended December 31, 1997, in conformity with generally accepted accounting principles. Our audits were made for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules listed in the accompanying index are presented for the purpose of additional analysis and are not a required part of the basic financial statements but are supplementary information required by the Department of Labor Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The Fund Information in the statements of net assets available for plan benefits and the statement of changes in net assets available for plan benefits is presented for purposes of additional analysis rather than to present the net assets available for plan benefits and changes in net assets available for plan benefits of each fund. The supplemental schedules and Fund Information have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated, in all material respects, in relation to the basic financial statements taken as a whole.

F-4 7 WEATHERFORD ENTERRA, INC. 401(k) SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS (1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - BASIS OF ACCOUNTING - The accompanying financial statements of the Weatherford Enterra, Inc. 401(k) Savings Plan (the "Plan") have been prepared on the accrual basis of accounting. 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, liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. ASSET VALUATION - The Plan's investments in Weatherford Enterra, Inc. (the "Company") common stock (the "Common Stock") (see Note 4), mutual funds, collective trusts and money market funds are reported in the accompanying statements of net assets available for plan benefits at their reported market value at the date of such statement. Differences between the market value and the value of the assets at the beginning of the plan year or at the time of purchase, if acquired during the year, are reported as unrealized appreciation (depreciation) of investments. Realized gains or losses on the sale of investments and withdrawals of investments are based on the value of the assets as of the beginning of the year or the time of purchase during the year. Unrealized appreciation (depreciation) of investments and realized gains or losses are recorded in the accompanying statement of changes in net assets available for plan benefits as net appreciation (depreciation) in market value of investments. The Merrill Lynch Retirement Preservation Trust Fund is a common/collective trust fund investing primarily in guaranteed investment contracts and U.S. Government securities. The guaranteed investment contracts are fully benefit responsive and are recorded at contract value, which approximates fair value. Effective yields approximated 6.6% as of December 31, 1997. Contract value is determined based on contributions made under the contract plus interest earned at the contract's rate less funds used to pay investment fees and withdrawals. Withdrawals of assets from the Plan are reported in the statement of changes in net assets available for plan benefits at market value, on a cash basis. EXPENSES - All expenses related to the administration of the Plan may be paid by the Company if it chooses to do so and, if not so paid, will be paid by the trustee of the Plan, using Plan assets. The Merrill Lynch Trust Companies ("Trustee") serves as Trustee. The Trustee receives compensation for its services in amounts agreed upon between the Company and the Trustee. For the year ended December 31, 1997, the administrative expenses and compensation to the Trustee for services were paid or reimbursed to the trust by the Company. (2) PROVISIONS OF THE PLAN - GENERAL - The Plan is maintained for the exclusive benefit of the participants in the Plan and is intended to aid the participants in providing for their retirement. Listed below are the options available for selection by participants as of December 31, 1997 and 1996: F-5 8 Merrill Lynch Global Allocation Fund Class A - a mutual fund that invests in equity, debt and money market securities. Merrill Lynch Equity Index Trust 1 - a collective trust that invests primarily in a portfolio of equity securities. Periodically, the trust will invest in futures contracts, however the goal is to be 100% invested in Standard & Poors 500 equities. Merrill Lynch Corporate Bond Fund Investment Grade Class A - a mutual fund that invests primarily in taxable fixed income securities. Merrill Lynch Capital Fund Class A - a mutual fund that invests primarily in equity securities, corporate bonds and/or money market securities. Davis New York Venture Fund, Inc. - a mutual fund that invests primarily in common stocks and/or convertible securities. Merrill Lynch Retirement Preservation Trust - a collective trust that invests primarily in government investment contracts, obligations of United States governmental securities and money market securities. Merrill Lynch USA Government Reserve Fund - a money market mutual fund that invests in United States treasury bills and notes. The net income of the fund is declared as dividends daily and reinvested at net asset value in additional shares. The fund seeks to maintain a constant $1.00 net asset value per share, although this cannot be assured. In order to maintain a constant net asset value of $1.00 per share, the fund may reduce the number of shares held by its shareholders. An investment in this fund is neither insured nor guaranteed by the U.S. Government. Weatherford Enterra, Inc. Common Stock Fund - a fund that invests in the Company's Common Stock. MERGERS INTO THE PLAN - During 1997, the Total Energy Services Company 401(k) Profit Sharing Plan (Total Plan) was merged into the Plan. As a result of the merger, the net assets of the Total Plan totaling approximately $6,700,000 were transferred to the Plan. In addition, during 1997, the Energy Industries Inc. Profit Sharing/401(k) Plan (EI Plan) and the Enterra Compression Company 401(k) Savings and Retirement Plan (ECC Plan) were merged into the Plan. As a result of the mergers, the net assets of the EI Plan totaling approximately $7,800,000 and the net assets of the ECC Plan totaling approximately $6,600,000 were transferred to the Plan. ADMINISTRATION - The Plan is administered by the administrative committee (the "Committee") consisting of one or more persons appointed from time to time by the Board of Directors of the Company. ELIGIBILITY - All employees are immediately eligible for participation in the Plan, except for employees who are subject to collective bargaining agreements, employees who are nonresident aliens and who receive no U.S. source income from the Company and employees who are members of other retirement plans sponsored by the Company or one of its subsidiaries outside the United States. F-6 9 PARTICIPANT CONTRIBUTIONS - An eligible employee may elect to contribute, by payroll deductions, 1% to 16% of his base earnings to the Plan on a pre-tax basis subject to certain limitations. An employee may also elect to contribute up to 16% of base after-tax earnings subject to certain limitations. The combination of these contributions, however, cannot exceed 16% of base earnings. In addition, participants made rollover contributions, which are included in employee contributions in the statement of changes in net assets available for plan benefits, totaling $572,769 in 1997. The Company acquired the rollover contributions primarily from participants of former employers' businesses. COMPANY CONTRIBUTIONS - The Company contributes an amount equal to 50% of the first 6% of each participant's pre-tax contributions after such participant has completed one year of active service. Pre-tax contributions up to 6% of a participant's compensation are eligible for Company matching contributions. In addition, the Company, solely at the discretion of the Board of Directors, may make discretionary contributions to the Plan. The Company declared a discretionary contribution to the Plan totaling $1,876,512 and $891,844 for 1997 and 1996, respectively. The Company made the 1997 discretionary contribution to the Plan in March 1998 and no forfeitures were utilized. Thus, included in the Company contributions receivable in the statements of net assets available for plan benefits for 1997 is the net contribution of $1,876,512 along with a year-end Company matching contribution receivable of $151,201. The 1996 discretionary contribution included $881,000 of utilized forfeitures to reduce the Company's discretionary contribution made to the Plan in April 1997. Thus, included in the Company contributions receivable in the statements of net assets available for plan benefits is the net contribution of $10,844 along with a Company matching contribution receivable of $111,844. Participants may allocate their contributions to the various available investment funds at their discretion. The Company matching contribution may, at the option of the Company, be made in cash or Company stock. If the match is made in cash, it is allocated to the various investment funds that the participant has elected on a pro rata basis to the participant contributions. The participants in the Plan are allowed to change their allocation and/or transfer all or part of their accumulated balance in a particular fund to another fund at any time. Any earnings on a fund's investments are reinvested in the same fund. Earnings and/or losses are allocated to the participant's accounts based on the number of units/shares held by the participant at the time the earnings and/or losses were achieved. VESTING AND FORFEITURE - Each participant is 100% vested in his participant contribution, the Company's discretionary contributions and related income. A participant's vested interest in the Company matching contributions and related income is determined by his years of vesting service in accordance with the following schedule: YEARS OF VESTING SERVICE VESTED INTEREST --------------- --------------- Less than 1 year 0% 1 year but less than 2 years 20% 2 years but less than 3 years 40% 3 years but less than 4 years 60% 4 years but less than 5 years 80% 5 years or more 100% Nonvested amounts are forfeited upon termination of employment by participants. The forfeited amounts are used to reduce future Company contributions. Unutilized forfeitures were $297,463 and none at December 31, 1997 and 1996, respectively. F-7 10 The Plan provides that any nonvested interests in a participant's accounts shall become fully vested upon the occurrence of a "change of control" of the Company that is not approved, recommended or supported by the Company's Board of Directors. A change of control is defined for purposes of the Plan as either a third person becoming the beneficial owner of 20% or more of the voting securities of the Company or a situation where, as a result of, or in connection with, a cash tender or exchange offer, merger or other business combination, sale of assets or contested election of directors, or any combination of such transactions, where the persons who were directors of the Company before the transaction cease to constitute a majority of the Board of Directors. WITHDRAWALS AND TERMINATION OF EMPLOYMENT - A participant may withdraw the value of his after-tax contributions to the Plan at any time and for any reason during the year, with a minimum withdrawal of $500. The participant's pre-tax contributions and the vested account balances from the Company contributions will be available to the participant upon termination of employment or severe and immediate financial hardship. A participant who has attained age 59 1/2 may withdraw the value of his pre-tax contributions. In the event of normal retirement, total and permanent disability or death while actively employed, the full value of the participant's account balance, including nonvested interests in such accounts, will be distributed to the participant or his beneficiaries. In the event of severe and immediate financial hardship, the entire value or a portion of the value of the participant's account balance may be distributed to the participant, with a minimum withdrawal of $500. Distributions from the Weatherford Enterra, Inc. Common Stock Fund may be in the Company's Common Stock or cash, as elected by the participant. (See Note 4.) LOANS TO PARTICIPANTS - Upon application by any participant of the Plan, subject to such rules as the Committee may establish, the Committee may in its discretion direct the Trustee to make a loan to such participant, not to exceed 50% of the participant's vested balance, and never more than $50,000. Any loan made pursuant to the Plan will bear interest, to be determined quarterly by the Committee, which was prime plus 1% during 1997 and 1996. The Trustee funds a participant's loan by liquidating, on a pro rata basis, the investments of the portions of the assets of the account or accounts from which the participant's loan is to be made. The loan is secured by a pledge of such participant's vested balance. As a condition to authorizing any loan, the Committee requires the participant to authorize the Company to make payroll deductions payable to the Trustee in repayment of such participant's loan plus interest. Any such loan requires level amortization with payments not less frequently than quarterly and must be repaid within five years unless the loan is to be used to acquire the principal residence of the participant, in which case the loan must be repaid within ten years. THE TRUSTEE AND PURCHASES OF INVESTMENTS - The Trustee maintains custody of the Plan's assets and uses participant and Company contributions to make investments in accordance with the Plan agreement. The Common Stock may be purchased on the open market or from the Company by the Trustee at a price equal to the closing price of the Common Stock on the national securities exchange on which the Common Stock is then listed. The market value per share of Common Stock was $43.75 and $30.00 on December 31, 1997 and 1996, respectively. AMENDMENT, SUSPENSION AND TERMINATION - Although the Company has not expressed an intent to do so, it has the right to suspend or terminate any or all provisions of the Plan at any time, except that no such action shall be taken which will, in the Committee's judgment, retroactively affect the rights of participants adversely. F-8 11 (3) FEDERAL INCOME TAX STATUS - The Plan obtained its latest determination letter on April 15, 1998, in which the Internal Revenue Service stated that the Plan, as then designed, was in compliance with the applicable requirements of the Internal Revenue Code. The Plan has been amended since receiving the determination letter. However, the Committee believes that the Plan is currently designed and being operated in compliance with the applicable requirements of the Internal Revenue Code. Therefore, they believe that the Plan was qualified and the related trust was tax exempt as of the financial statement dates. (4) SUBSEQUENT EVENT - On May 27, 1998, EVI, Inc. completed its previously announced merger with the Company. EVI, Inc. is the surviving company and changed its name to EVI Weatherford, Inc. Under the terms of the merger agreement, Weatherford stockholders received 0.95 of a share of EVI common stock for each share of Weatherford Enterra, Inc. common stock held. The Company is currently unable to predict the timing or the ultimate impact that these recent developments will have on the Plan.
