DESCRIPTION OF PLAN The following description of the STB Systems, Inc. 401(k) Savings Plan (the "Plan") provides only general information. Participants should refer to the Plan document for a more complete description of the Plan's provisions. GENERAL The Plan, established in 1991, is a nondiscriminatory defined contribution plan for all employees of the Company who have completed six months of credited service and elect to participate. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). It has been amended to incorporate legislative changes required by the various tax acts enacted since 1984. CONTRIBUTIONS Eligible employees may elect to make contributions to the Plan by means of compensation reductions of up to 15% of their compensation. Employees may allocate their contributions to investment options in 1% increments. The Company matches 25% of each dollar of employee tax deferred contributions up to a maximum of 4% of each employee's annual pay. PARTICIPANTS' ACCOUNTS Participants' accounts are credited with the participants' contributions and an allocation of (a) the Company's contribution and (b) Plan earnings. VESTING OF CONTRIBUTIONS Participants' contributions to the Plan are 100% vested at all times. Employer contributions to the Plan are vested in accordance with a Plan document schedule based on the participant's length of service with the Company. The schedule provides for full vesting after five years of credited service. INVESTMENT OPTIONS Eligible participants have six investment options including a Fixed Income option, a Balanced option, a Growth Stock option, an Aggressive Growth option, an Employer Stock Fund, and a Bond option. Cecil & Co. is the custodian for the Employer Stock Fund and Nationwide Mutual Insurance Company is the custodian for the five remaining plan assets. Southwest Guaranty Trust Company is the trustee of all the Plan assets and Cecil & Co. is the record keeper. On February 14, 1995, participants in the Plan were granted a one-time option to reallocate existing participant investment accounts to purchase STB Systems, Inc. common stock in conjunction with the Company's initial public offering which became effective February 14, 1995. 4 STB SYSTEMS, INC. 401(k) SAVINGS PLAN NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - ------------------------------------------------------------------------------ The assets from a predecessor custodian remain with New England Company as custodian and are included in Plan assets. These assets are a prior fixed income option. No further contributions can be made to this investment option. Participants may change their investment options daily. PAYMENT OF BENEFITS In the event of a participant's termination of employment, retirement, disability, or death, the participant or beneficiary may elect to receive an amount equal to the vested value of their account in either a lump-sum or periodic payments of substantially equal installments at least annually. PARTICIPANT NOTES RECEIVABLE Participants may borrow from their fund accounts a minimum of $1,000 up to a maximum equal to the lesser of $50,000 or 50 percent of their vested account balance. All loans are required to be repaid within five years of the loan unless the loan is to be used for the purchase of a primary residence. The loans are secured by the balance in the participant's account and bear interest at prime plus 1%. Principal and interest are repaid through payroll deductions. Cecil & Co. is the custodian of the Loan Account. FORFEITED ACCOUNTS At December 31, 1996 and 1995, forfeited nonvested accounts totaled $1,346 and $1,869, respectively. These funds were held in a money market account at December 31, 1996 and 1995, and will be used to reduce future employer contributions. EXPENSES OF ADMINISTERING THE PLAN The Company pays expenses incurred in the administration of the Plan. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF ACCOUNTING The financial statements of the Plan are prepared in accordance with generally accepted accounting principles. Assets are stated at market value; unrealized appreciation and depreciation of the assets are reflected in the asset balances. Gains or losses on investments are realized at the time of sale. 5 STB SYSTEMS, INC. 401(k) SAVINGS PLAN NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - ------------------------------------------------------------------------------ FEDERAL INCOME TAXES Management of the Company believes that the Plan is qualified under Section 401(a) of the Internal Revenue Code and therefore believes the trust is exempt from taxation under Section 501(a). The Internal Revenue Service granted a favorable letter of determination to the Plan in October, 1993. Generally, contributions to a qualified plan are deductible by the Company when made, earnings of the trust are tax exempt, and participants are not taxed on their benefits until withdrawn from the Plan. Management of the Company is unaware of any variations in the operations of the Plan from the terms of the Plan document as amended. The Plan has complied with the fidelity bonding requirements of ERISA. VALUATION OF SECURITIES Valuation of securities is based on the last recorded sales price at year-end, as reported by the principal security exchange on which the security is traded. Securities transactions are recorded on a trade-date basis. RECOGNITION OF INTEREST INCOME Interest is recognized on an accrual basis. DETERMINATION OF UNREALIZED GAIN OR LOSS ON INVESTMENTS Unrealized appreciation or depreciation in the fair value of investments held at year-end and gain or loss on sale of investments during the year are determined using the fair value at the beginning of the year or purchase price if acquired during the year. REPORTABLE TRANSACTIONS For the Plan year 1996, the reportable transactions as defined in Item 27d and Part V of Form 5500 are listed in Schedule II. 3. INVESTMENTS Investments are maintained by Nationwide Mutual Insurance Company and Cecil & Co. as custodians, except for certain assets from a predecessor custodian which are held by New England Company. 6 STB SYSTEMS, INC. 401(k) SAVINGS PLAN NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -
