REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Administrative Committee First Cash 401(k) Profit Sharing Plan Arlington, Texas We have audited the accompanying statements of net assets available for benefits of the First Cash 401(k) Profit Sharing Plan (the "Plan") as of December 31, 2005 and 2004, and the related statement of changes in net assets available for benefits for the year ended December 31, 2005. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the auditing standards of the Public Company Accounting Oversight Board (United States). 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 consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan's internal control over financial reporting. Accordingly, we express no such opinion. 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 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 benefits of the First Cash 401(k) Profit Sharing Plan as of December 31, 2005 and 2004, and the related statement of changes in its net assets available for benefits for the year ended December 31, 2005, in conformity with United States generally accepted accounting principles. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets held for investment purposes at December 31, 2005, is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole. /S/ HEIN & ASSOCIATES LLP Dallas, Texas May 18, 2006

FIRST CASH 401(k) PROFIT SHARING PLAN NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2005 AND 2004 1. DESCRIPTION OF PLAN ------------------- The following description of the First Cash 401(k) Profit Sharing Plan (the "Plan") provides only general information. For a more complete description of the Plan's provisions, participants should refer to the Plan agreement. General ------- The Plan is a salary deferral plan covering substantially all U.S.-based employees of First Cash Financial Services, Inc. (the "Company" or the "Employer") who have completed one year of service with the Company. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). The trustee of the Plan is Frontier Trust Company, FSB. Contributions ------------- Each year, participants may contribute to the Plan an amount up to 15% of their annual compensation. Each participant's annual contribution shall not exceed the maximum amount allowed for deferral for U.S. federal income taxes, which was generally $14,000 for 2005. The amount of a participant's annual compensation that may be taken into account for purposes of determining the Company's matching contribution for any purpose under the Plan shall not exceed an amount prescribed annually by the IRS. The Company contributes to the Plan a matching amount equal to 50% of the first 3% of the participant's annual compensation that is contributed to the Plan. In addition, a special discretionary contribution as determined by the Company may be contributed, pro rata, based upon each participating employee's compensation to the total compensation of all participating employees. No such contribution was made in 2005. If a participant makes a contribution during any year in an amount which exceeds the maximum amount allowed under IRS rules pertaining to highly compensated employees, the contribution is refunded and the matching Company contribution on such additional participant contribution may be forfeited by the participant and applied to reduce the employer's matching contribution to the Plan for the following year. Management believes that the Plan is in compliance with the funding requirements of ERISA. Participant Accounts -------------------- Each participant's account is credited with the participant's contribution, allocations of the Company's matching contributions and Profit Sharing contributions, if applicable. Forfeitures of the non- vested portion of terminated participants' accounts may be applied first to payment of plan administrative expenses and any remaining forfeitures will be used to reduce future Company contributions to the Plan. The various participant allocations are based on a percentage of the participant's elective deferral or compensation in relation to total compensation of participants, as defined in the Plan agreement. Vesting ------- Participants are immediately vested in their contributions (including rollovers) plus actual earnings thereon. Vesting in the remainder of their accounts is generally based on years of continuous service with the Company, which is determined as a twelve consecutive month period ending on each anniversary of a participant's date of hire. A participant is 100% vested after six years of credited service. A participant is also 100% vested upon reaching retirement age or if employment is terminated by reason of total and permanent disability or death. Investment Options ------------------ Upon enrollment into the Plan, a participant may direct his or her employee contributions in any increment to the Company's common stock or any of the mutual fund investment options offered by Frontier Trust Company, the custodian of the Plan. Participants may change the allocation of their existing funds and future contributions at any time. Payment of Benefits ------------------- Participants whose employment terminates for any reason (except death) are generally entitled to receive the vested portion of their account in the form of a lump sum or installment distribution payable in cash. During 2005, the Plan was amended to lower the mandatory cashout level for terminated participants from $5,000 to $1,000. Certain participants may be eligible to receive benefits in the form of annuity payments. There were no benefits payable to participants at December 31, 2005 or at December 31, 2004. Participant Loans ----------------- A participant may apply to the plan administrator for a loan under the Plan. All loans made by the trustees shall be subject to the terms and conditions set forth in the Plan Document and Trust Agreement. Participants may borrow up to one-half of the participant's vested account balance or $50,000, whichever is less. The loans will bear a reasonable rate of interest based upon prevailing commercial rates for loans of similar types. Repayments of the loan balance, plus interest, are made bi-weekly through after-tax payroll deductions, not to exceed five years, unless the loan was obtained to acquire a home, then over a reasonable period of time as determined by the trustee. A participant may have up to two loans outstanding at any one time. Participant loans are collateralized by the respective participant accounts. Forfeitures ----------- Participants who terminate employment prior to being fully vested in the Company's matching contributions forfeit non-vested amounts. At December 31, 2005, there was approximately $51,000 of forfeited non-vested accounts. Forfeitures of Company matching contributions are used to reduce future Company contributions to the Plan. In 2005, Company matching contributions were reduced by approximately $56,000 from forfeited, non-vested accounts. Forfeitures of discretionary Company contributions are reallocated among all remaining participants. Administrative Fees ------------------- The Company has paid, at its discretion, the administrative expenses of the Plan. Administrative expenses incurred in 2005 were approximately $40,000. Tax Status ---------- The Internal Revenue Service ("IRS") has determined and informed the Company by a letter dated November 27, 2001, that the Plan is designed in accordance with applicable sections of the Internal Revenue Code. 2. SUMMARY OF ACCOUNTING POLICIES ------------------------------ Basis of Accounting ------------------- The financial statements and supplemental schedules are prepared on the accrual basis of accounting. Valuation of Investments ------------------------ Shares of registered investment companies are valued at quoted market prices which represent the net asset value of shares held by the Plan at year-end. Equity securities are valued at fair value using quoted market prices. Participant loans and investments in money market funds are stated at cost, which approximates fair value. Reinvested income, accrued interest and dividends are reflected as additions to the cost basis of the investments. Investment transactions are recorded on a trade-date basis. Payment of Benefits ------------------- Benefits are recorded when paid. Benefits due to participants who have elected to withdraw from the Plan but have not been paid, are deducted from net assets available for benefits. Amounts allocated to withdrawing participants at December 31, 2005 were immaterial. Use of Estimates ---------------- The preparation of financial statements in conformity with United States generally accepted accounting principles as applied to defined contribution employee benefit plans requires the Plan's management to make estimates and assumptions that affect the amounts reported in these financial statements and accompanying notes. Actual results could differ from those estimates. 3. INVESTMENTS ----------- Investments, at fair value, consisted of the following as of December 31: 2005 2004 --------- --------- Mutual Funds: Merrill Lynch Fundamental Growth Fund Class A $ 346,385 $ 294,372 Merrill Lynch Basic Value Fund Class A 317,464 297,086 Merrill Lynch Global Allocation Fund Class A 382,219 (a) 417,714 Merrill Lynch FD Core Bond Class A 209,688 175,611 Oppenheimer Small Cap Value Fund Class A 207,043 29,686 Davis New York Venture Fund Class A 369,927 320,011 --------- --------- 1,832,726 1,534,480 Money Market Fund: Merrill Lynch Retirement Preservation Trust (a) 1,405,087 (a) 1,289,646 First Cash Financial Services, Inc. common stock (a) 4,227,480 (a) 4,031,237 Participant loans (a) 532,054 (a) 577,352 --------- --------- $7,997,347 $7,432,715 ========= ========= (a) Represents 5% or more of the Plan's net assets.

PLAN TERMINATION ---------------- Although it has not expressed any intent to do so, the Company has the right under the Plan agreement to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants become 100% vested in their accounts.
