Contributions are made by employees and matched by The Houston Exploration Company (the "Company" or "Houston Exploration"). The following description of the Plan provides only general information of Plan provisions during the years ended December 31, 2003 and 2002. Participants should refer to the Plan document for a more complete description of the Plan's provisions. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). Participation in the Plan is voluntary. All employees of the Company become eligible to participate in the Plan upon reaching 21 years of age and completing one month of service. Plan entry dates are the first of each calendar quarter or January 1st, April 1st, July 1st, and October 1st. Participants may elect to reduce their gross compensation by any percentage amount between 1% and 12.5% and have this amount deposited into the Plan as pre-tax contributions. In accordance with Internal Revenue Service ("IRS") guidelines, employee contributions were limited to $12,000 and $11,000, respectively, for the years ended December 31, 2003 and 2002. Beginning in 2002, the limit on elective deferrals by employees increases by $1,000 each year until the limit reaches $15,000 in 2006. After 2006, the limit will be subject to cost-of-living increases. In addition, also beginning in 2002, Plan participants who are age 50 or over at the end of the calendar year are permitted to make a catch-up contribution. The catch-up contribution for was $2,000 for 2003 and $1,000 for 2002. The catch-up contribution increases by $1,000 each year until it reaches $5,000 in 2006. The catch-up contribution cannot exceed the lesser of the catch-up contribution limit or the excess of the participant's compensation over the elective deferrals that are not catch-up contributions. The Company may, at its discretion, make certain matching contributions based on employee contributions. During 2003 and 2002, the Company elected to match 100% of employee contributions up to a maximum of 12.5%. In order for the Plan to satisfy various nondiscrimination tests required under applicable Federal regulations, certain employees designated as highly compensated employees under Internal Revenue Code may be limited, from time to time, in the amount they may contribute to the Plan. For any Plan participant, total annual contributions (the sum of employee plus employer contributions) may not exceed the lesser of $40,000 or 100% participant compensation for both 2003 and 2002. Participants are fully vested in their contributions at the time the contributions are made. Participants commence vesting in the Company's contributions and any earnings thereon, upon completion of one year of service at the rate of 20% per year and become fully vested upon completion of their fifth year of service. Death or disability of a participating employee results in immediate full vesting of Company matching contributions. If employment is terminated for reasons other than death or disability unvested participant account balances are forfeited back to the Plan. Forfeitures of employer's matching contributions can be used by the Plan to reduce future employer contributions. Forfeitures totaled $7,671 and $13,825, respectively during 2003 and 2002, none of which were used to reduce the Company's match. Funds are available for withdrawal or distribution from the Plan at retirement (defined by the Plan as age 65), death, disability, hardship (as defined by the IRS) or termination of employment with the Company. Distributions prior to age 59 1/2 may be subject to an early withdrawal penalty imposed by the IRS of 10% in addition to Federal withholding tax required on the distributed funds. Participants are permitted to rollover 401(k) money from previous employer plans and employees leaving the Company have the option to rollover Plan money into an Individual Retirement Account ("IRA"). Participant loans are permitted in accordance with the loan provisions in the Plan document. A participant may borrow up to 50% of their vested account balance not to exceed a maximum of $50,000. The minimum loan amount is $1,000. The interest rate charged on participant loans is commensurate with the prevailing interest rate charged on similar commercial loans. Loans are repaid through payroll deductions. Upon termination of employment, the participant may either repay any outstanding loan balance in full or incur a tax liability on the unpaid balance. 5 It is the intention of the Company that the Plan will continue, although the Plan may be amended or discontinued at any time subject to the provisions of ERISA. In the event the Plan is terminated, Plan assets and income will be distributed (after payment of Plan expenses) exclusively to active and retired participants. Plan assets are invested in an unallocated group annuity contract with ING Life Insurance and Annuity Company ("ILIAC"). ILIAC uses two investment vehicles for Plan funds: o an allocated annuity contract which is referred to as a "General or Fixed Account"; and o a "Separate Variable Annuity Account D" which is a pooled separate account established under Connecticut State Insurance law. Funds held in the General Account earn interest at market rates and funds held in the Separate Variable Annuity Account D are invested in various mutual funds. ILIAC is the principal insurance company in the ING Financial Services ("ING") group of companies controlled by the ING Group ("ING"). Various mutual funds, both third party funds and funds owned and controlled by ING, together with Houston Exploration common stock, are available as investment options for Plan contributions. ING purchases shares of the various mutual funds or common stock and depending on the investment vehicle selected, ING will fund the investment acquisition through ILIAC's general account or through ILIAC's pooled separate account D. Plan participants individually direct the investment of both their contributions and their share of the Company's matching contributions. See Note 7 -- Investments, for discussion of realized and unrealized gains and losses on Plan assets. NOTE 2 -- PLAN SPONSOR, ADMINISTRATOR AND TRUSTEE Houston Exploration is the Plan Sponsor and Administrator. Houston Exploration contracts with a third party, a "Third Party Administrator", to provide various accounting and record keeping services for the Plan. ING serves as the Plan custodian as the Plan's assets are invested in ILIAC's allocated annuity contract and its variable annuity separate account D. ING National Trust is the Plan's trustee and is the Plan's third party administrator providing all accounting and record keeping services for the Plan. ING Investment Services, LLC is the Plan's broker to provide brokerage services. With the exception of brokerage fees, which are built into the unit cost of a fund, all expenses of administering the Plan are paid by Houston Exploration. See Note 8 - Subsequent Events for discussion of change in trustee and third party administrator on January 1, 2004 pursuant to the January 1, 2004 adoption of a new plan agreement. NOTE 3 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Accounting. The accounting records of the Plan are maintained on a cash basis. The financial statements of the Plan are prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States. Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States may require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual amounts could differ from those estimates. Investment Valuation. Investments in the mutual funds are reported at fair market value as determined by the unit value reported by ING. Participant loans are stated at fair value. Investments in Houston Exploration common stock are valued at a quoted market price. Any other assets are reported at cost, which in the opinion of management approximates fair value. NOTE 4 -- FEDERAL INCOME TAXES The IRS issued a determination letter, dated November 7, 2001, stating that the Plan, as designed, meets the requirements of Section 401 (a) of the Internal Revenue Code and was exempt from taxation. The Plan Administrator believes the Plan continues to operate in accordance with IRS regulations and therefore continues to be tax-exempt. 6 NOTE 5 -- RELATED PARTIES During 2003 and 2002, the Plan had a total of 20 investment options that included the follow o 10 funds controlled by ING Financial Services; o nine third party mutual funds; and o the common stock of Houston Exploration, the Plan Sponsor and Administrator. NOTE 6 -- OTHER INFORMATION Prohibited Transactions. As required by ERISA Section 2510.3-102, the Houston Exploration is required to segregate employee contributions to the Plan from its general assets as soon as practicable, but in no event more than 15 business days following the end of the month in which amounts are withheld from wages. Due to the change in Plan administrator from ING to MFS during the fourth quarter of 2003 (see Note 8 - Subsequent Events), contributions from the November 30, 2003 payroll were not able to be transferred to and accepted by the new Third Party Plan Administrator (MFS) until December 30, 2003, which exceeded the 15 business day limitation by 7 business days. Total contributions and loan repayments for the November 30, 2003 pay period were $60,160, of which $28,780 represented employee contributions, $27,681 represented the Company's matching contributions and $3,699 represented loan repayments. Contributions for this pay period are considered a prohibited transaction. The Company made an interest payment of $2,587 to compensate the Plan for lost investment earnings relating to this prohibited transaction. There were no prohibited transactions during 2002. The Plan had no lease commitments or leases in default and no loans or fixed income obligations in default, as defined by ERISA Section 2520.103(b)(3)(E) for the years ended December 31, 2003 and 2002. NOTE 7 -- INVESTMENTS The fair market value of individual investments that represent 5% or more of the Plan's total net assets as of December 31, 2003 and 2002: DECEMBER 31, 2003 2002 ----------------------------------- ING non-interest bearing cash (see Note 8) $ 9,983,704 $ - ING Fixed Account - 2,568,689 Fidelity VIP Growth Portfolio - 1,222,752 ING Growth and Income VP - 668,070 Fidelity VIP Equity-Income Portfolio - 634,868 ING Money Market VP - 406,501 -------------- -------------- Total comprising 5% or more of total Plan assets 9,983,704 5,500,880 All other Plan assets as a group 421,064 1,796,292 --------------- --------------- Total Plan assets $ 10,404,768 $ 7,297,172 =============== =============== For the year ended December 31, 2003, the Plan's investments (including investments bought, sold, as well as held during the year) appreciated in fair value by $1,601,384. For the year ended December 31, 2002, the Plan's investments (including investments bought, sold, as well as held during the year) depreciated in fair value by $1,160,663. There are no dividends or realized and unrealized gains with respect to separate account units of participation. Dividends and realized and unrealized gains and losses for the underlying funds are factored into the value of the separate account funds. The value of the separate account unit of participation is determined by dividing the total value of the separate account by the total number of units of participation held by the plans invested in the separate account. The value of the separate account includes the dividends earned and any realized or unrealized gains or losses associated with the underlying investments. the table below provides the change in fair value during the respective year for each of the Plan's investment vehicles. The net appreciation or (depreciation) in fair value includes both realized and unrealized gains. 7 Year Ended December 31, 2003 2002 ---------------------------------- Change in Value during Period (1) General Account: ING Fixed Account $ 228,507 $ 111,601 (2) Pooled Separate Accounts: ING Growth and Income VP 164,087 (259,592) ING Money Market VP 1,186 3,200 ING Bond VP 14,041 9,885 ING Balanced Fund 55,190 (13,941) ING Ascent 1,280 (530) ING Crossroads 2,891 (71) ING Index Plus Large Cap VP 43,419 (19,610) ING Value Opportunity VP 47,423 (29,870) ING Index Plus Mid Cap VP 61,704 (11,545) JP Morgan Fleming International Portfolio 30,119 (43,708) ING Salomon Brothers Aggressive Growth Portfolio 80,050 (148,334) MFS Capital Opportunities 15,118 (9,840) Fidelity VIP Overseas Portfolio 45,088 (22,271) Fidelity VIP Equity-Income Portfolio 242,002 (128,878) Fidelity VIP Growth Portfolio 426,973 (522,667) Janus Aspen Growth 23,077 (15,577) Janus Aspen Aggressive Growth 48,405 (21,153) Janus Aspen Worldwide Growth 36,288 (27,391) Houston Exploration common stock 34,536 (10,371) ------------ ----------- Net appreciation (depreciation) in Plan assets $ 1,601,384 $(1,160,663) ============ ============ ---------- (1) General Account investment vehicle is the ING Fixed Account and is made available through an annuity contract issued by ILIAC.

NOTE 8 -- SUBSEQUENT EVENTS Effective January 1, 2004, Houston Exploration adopted a new Plan agreement with MFS Retirement Services, Inc., a division of Massachusetts Financial Services ("MFS").

In conjunction with the adoption of the new Plan agreement with MFS, the Company entered into a new trustee agreement with MFS Heritage Trust Company and a new Third Party Administrator agreement with MFS Corporate Plan Services. At December 31, 2003, all Plan assets held at ING were converted to cash in preparation for the transfer to MFS on January 2, 2004. Participant fund balances were "mapped" from ING funds to new MFS funds and investments in Houston Exploration common stock were liquidated and reallocated among various other Plan investment options prior to transfer. Plan assets transferred from ING to MFS on January 2, 2004 totaled $10,294,715 that included $9,983,704 in cash and $311,011 in participant loans.
