Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. General The Plan is a defined contribution 401(k) retirement savings plan, adopted January 1, 1993. Employees of PetroCorp Incorporated and Fidelity Gas Systems, Inc., a wholly owned subsidiary, (the Company) become eligible to participate in the Plan after six months of service with the Company. The entry dates are January 1 and July 1 of each year. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). All Plan contributions are invested in separate pooled accounts under an annuity contract with Principal Mutual Life Insurance Company (Principal) or in common stock of the Company. Contributions Participants may contribute to the Plan subject to certain Internal Revenue Code limitations. The Company may match up to 100 percent of each participant's contributions not to exceed six (6) percent of each participant's annual compensation. Additionally, the Company may make discretionary contributions on behalf of the participants. In any event, total contributions by the participant and the Company may not exceed 20 percent of the participant's annual compensation. During 1996 and 1995, each participant could contribute up to 14 percent of his annual compensation with the Company matching up to six (6) percent, except in certain cases subject to Internal Revenue Code limitations. The Plan also allows participants to "rollover" contributions that have been made to other qualified plans. Participant accounts Each participant's account is credited with the participant's contributions, the Company's contributions and a pro rata share of the earnings of each fund in which the participant has invested. The benefit to which a participant is entitled is the benefit that can be provided from the participant's account. Vesting Participants are fully vested at all times in their individual contributions and "rollover" contributions plus actual earnings thereon. Vesting in employer contributions and related earnings is based on the participant's employment commencement date and years of continuous service. Participant's whose employment commencement date occurred before January 1, 1994 are 100% vested. Participant's whose employment commencement date occurred on or after January 1, 1994 are vested as follows: 4 Vesting Service Vesting (whole years) Percentage ------------------ ----------- Less than 1 year 0% 1 year 25% 2 years 50% 3 years 75% 4 or more years 100% In addition, participants also become fully vested in their employer contributions and related earnings upon retirement, at or after age 65, or upon death or total disability of the participant. Investment options Effective January 1, 1994, upon enrollment in the Plan, a participant may direct contributions in any of fourteen investment options as follows: Guaranteed Interest Account - Funds are invested in a guaranteed investment contract (GIC) with Principal. U.S. Stock Account - This is a separate pooled account with Principal in which the funds are invested in various stocks of U.S. companies with the intent to earn higher long-term rates of return. Money Market Account - This is a separate pooled account with Principal in which the funds are invested in high quality commercial paper with average maturities kept under 30 days to ensure current money market rates. Real Estate Account - This is a separate pooled account with Principal in which the funds are invested in equity investments in modern, developed, income-producing warehouses, office buildings and retail centers in major U.S. metropolitan areas. Earnings consist of property value changes and net rental income. Bond & Mortgage Account - This is a separate pooled account with Principal in which the funds are invested in investment grade private placement bonds, commercial mortgages, public corporate bonds and mortgage-backed securities, all generally mature within five to 10 years. International Stock Account - This is a separate pooled account with Principal in which the funds are invested in stocks of non-U.S. companies located primarily in Europe and Southeast Asia. Government Securities Account - This is a separate pooled account with Principal in which the funds are invested primarily in very high quality government mortgage-backed securities. Stock Index Account - This is a separate pooled account with Principal in which the funds are invested in the same stocks and in the same proportions as those stocks included in the Standard & Poor's 500 Stock Index. Value Stock Account - This is a separate pooled account with Principal in which the funds are invested in primarily income-producing common stocks that are under valued in the marketplace according to traditional measures of value. Small Company Stock Account - This is a separate pooled account with Principal in which funds are invested in stocks of smaller, fast-growing companies. 5 Growth Stock Account - This is a separate pooled account with Principal in which funds are invested in stocks of large, established companies whose earnings are expected to grow faster than the average company. Bond Emphasis Balanced Account - This is a separate pooled account with Principal in which funds are invested in many asset classes, but emphasizes fixed income. This account invests 50 to 100 percent of the funds in Principal fixed-income separate pooled accounts, with the remainder in Principal equity separate pooled accounts. Stock Emphasis Balanced Account - This is a separate pooled account with Principal in which funds are invested in many asset classes, but emphasizes equities. This account invests 50 to 100 percent of the funds in Principal equity separate pooled accounts, with the remainder in Principal fixed- income separate pooled accounts. Company Stock - Funds are invested in the common stock of the Company. Payment of benefits Distribution of the participant's entire account balance becomes due and payable upon retirement, at or after age 65, or upon death or total disability of the participant. Such account balances may be distributed either in a lump-sum distribution or in installments, as described in the Plan agreement. Upon termination of employment, a participant may elect to receive a lump-sum distribution equal to the vested balance of the participant's account or continue to participate in the Plan investments. If the vested balance is less than $3,500, payment is made as soon as administratively practicable after termination. Additionally, participants may make hardship withdrawals from their individual contribution accounts at specified times during the Plan year, subject to certain restrictions. Participants' notes receivable Under the terms of the Plan, with certain restrictions, participants may borrow from their accounts a minimum of $1,000 up to a maximum of the lessor of $50,000 or 50 percent of their vested account balances. A loan is secured by the vested balance in the participant's account and bears interest at the prime interest rate plus two (2) percent. During 1996, the interest rates ranged from 10.25 percent to 11.00 percent. During 1995, the interest rates ranged from 9.75 percent to 11.00 percent. NOTE 2 - SUMMARY OF ACCOUNTING POLICIES: Under the Department of Labor Rules and Regulations for Reporting and Disclosure under ERISA, the Plan files Form 5500-C/R which is required for employee benefit plans with fewer than 100 participants. Employee benefit plans with 100 or more participants are required to file Form 5500. Those plans filing Form 5500 are required to prepare audited financial statements as well as all applicable schedules required by Section 2520.103-10 of the Department of Labor's Rules and Regulations for Reporting and Disclosure under ERISA. Such requirements are not mandated for those plans filing Form 5500-C/R. Accordingly, the attached financial statements are unaudited and the above mentioned schedules are not presented. Method of accounting The Plan's financial statements are prepared on the accrual basis of accounting. 6 Investments Plan investments, other than the GIC's, are stated at fair value. The Company stock is valued at its quoted market price. Separate pooled accounts are valued at net asset value representing the value at which units of the account may be purchased or redeemed. The Plan's GIC's are valued at contract value. Contract value represents contributions made under the contract plus interest at the guaranteed rate. Contributions Participant contributions are recorded in the period during which the Company makes payroll deductions from the Plan participants' earnings. Matching Company contributions are recorded in the same period. NOTE 3 - INVESTMENTS: Individual investments representing five (5) percent or more of the Plan's net assets are as follows: December 31, -------------------- 1996 1995 -------------------- INVESTMENTS AT FAIR VALUE AS DETERMINED BY QUOTED MARKET PRICE: Pooled separate accounts: Principal: U.S. Stock Account $204,474 $168,427 International Stock Account 182.693 167,408 Value Stock Account 145,719 122,732 Growth Stock Account 103,898 - Small Company Stock Account 355,374 320,327 Stock Emphasis Balanced Account - 89,242 Company Stock: PetroCorp Incorporated Common Shares $445,651 $324,224 INVESTMENTS AT CONTRACT VALUE: Guaranteed Investment Contracts with Principal $128,516 $111,136 7 The net realized and unrealized appreciation (depreciation) in fair value of investments included in the statements of changes in net assets available for Plan benefits were $317,521 and $125,875 for the years ended December 31, 1996 and 1995, respectively, and consisted of the following: Year ended December 31, -------------------- 1996 1995 -------------------- NET APPRECIATION (DEPRECIATION) IN INVESTMENTS AT FAIR VALUE AS DETERMINED BY QUOTED MARKET PRICE: Pooled separate accounts: Principal: U.S. Stock Account $ 42,124 $ 36,402 Money Market Account 1,251 1,111 Real Estate Account 413 405 Bond & Mortgage Account 2,925 10,592 International Stock Account 41,432 21,596 Government Securities Account 1,970 4,958 Stock Index Account 12,905 10,503 Value Stock Account 22,342 31,105 Small Company Stock Account 57,588 68,373 Growth Stock Account 14,952 14,179 Bond Emphasis Balanced Account 4,921 7,703 Stock Emphasis Balanced Account 14,978 15,005 Company Stock 99,720 (96,057) -------- -------- $317,521 $125,875 ======== ======== NOTE 4 - GUARANTEED INVESTMENT CONTRACTS: The Plan entered into five-year GIC's with Principal in each of the last three years. The GIC's provide for guaranteed returns ranging from 6.10% to 6.99% on contributions invested over the five-year terms of the contracts. The GIC's are included in the financial statements at contract value as reported to the Plan by Principal. NOTE 5 - PLAN TERMINATION: Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become fully vested in their accounts.
