ITEM 4. DESCRIPTION OF SECURITIES. Not applicable. ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL. Not applicable. ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS. MICHIGAN BUSINESS CORPORATION ACT. The Company is organized under the Michigan Business Corporation Act (the "MBCA") which, in general, empowers Michigan corporations to indemnify a person who was or is a party or is threatened to be made a party to an action, suit or proceeding, whether civil, criminal, administrative or investigative and whether formal or informal, other than an action by or in the right of the corporation, by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, partner, trustee, employee or agent of another enterprise, against expenses, including attorneys' fees, judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred in connection therewith if the person acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation or its shareholders and, with respect to a criminal action or proceeding, if the person had no reasonable cause to believe his or her conduct was unlawful. The MBCA also empowers Michigan corporations to provide similar indemnity to such a person for expenses, including attorneys' fees, and amounts paid in settlement actually and reasonably incurred by the person in connection with actions or suits by or in the right of the corporation if the person acted in good faith and in a manner the person

reasonably believed to be in or not opposed to the interests of the corporation or its shareholders, except in cases where the person has been found liable to the corporation and the court has not determined that the person is fairly and reasonably entitled to indemnification in view of all relevant circumstances. If a person is successful in defending against a derivative action or third-party action, the MBCA requires that a Michigan corporation indemnify the person against expenses incurred in the action. The MBCA also permits a Michigan corporation to purchase and maintain on behalf of such a person insurance against liabilities incurred in such capacities. The MBCA further permits Michigan corporations to include a provision in their articles of incorporation eliminating or limiting the personal liability of directors to the corporation or its shareholders for money damages for a breach of their fiduciary duty other than for any of the following: (i) the amount of a financial benefit received by a director to which he or she is not entitled; (ii) intentional infliction of harm on the corporation or the shareholders; (iii) a violation of Section 551 of the MBCA; or (iv) an intentional criminal act. If such a provision is included in the corporation's articles of incorporation, the corporation may indemnify its directors without a determination that the applicable standard of conduct has been met, except where (i) the director received a financial benefit to which he or she is not entitled; (ii) intentionally inflicted harm on the corporation or the shareholders; (iii) violated Section 551 of the MBCA; or (iv) intentionally committed a criminal act. ARTICLES OF INCORPORATION. As permitted by the MBCA, the Company's Articles of Incorporation limit the liability of directors to the Company and its shareholders for monetary damages to the extent provided by law. As a result, shareholders of the Company may be unable to recover monetary damages against directors for actions taken by them which constitute negligence or gross negligence or which are in violation of their fiduciary duties, although it may be possible to obtain injunctive or other equitable relief with respect to such actions. The Articles of Incorporation also obligate the Company to indemnify directors and officers to the fullest extent permitted by law. If a claim for indemnity is not paid in full by the Company within thirty days after a written claim has been received, the director or officer may bring suit against the Company to recover the unpaid amount of the claim and, if successful, is also entitled to be paid the expense of prosecuting the claim. In any action brought by the indemnitee to enforce a right under the indemnification provisions in the Articles of Incorporation or by the Company to recover payments by the Company of advances, the burden of proof shall be on the Company. BYLAWS. Similarly, the Company's Bylaws require the Company to indemnify its directors and officers to the fullest extent permitted by law. Such indemnification will be provided if such persons acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the Company or its shareholders, or in respect to a criminal proceeding, had no reasonable cause to believe such conduct was unlawful. The Company's Bylaws also provide that the Company may provide insurance on behalf of any person who is or was a director or officer of the Company, or was at the request of the Company serving as a director, officer, employee or agent of another entity, with respect to any liability incurred or asserted by or against them as a result of their status with the Company or such other entity. The Company has obtained such insurance. ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED. Not applicable.

UNDERTAKINGS. (1) The undersigned registrant hereby undertakes to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any facts or events arising after the effective date of this registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement; (iii) to include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement; provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this registration statement. (2) The undersigned registrant hereby undertakes that, for the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) The undersigned registrant hereby undertakes to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (4) The undersigned registrant hereby undertakes that, for the purpose of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (5) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

EXHIBIT 5 INTERNAL REVENUE SERVICE DEPARTMENT OF THE TREASURY Washington, DC 20224 Plan Description: Prototype Standardized Profit sharing Plan with COD FFN: 50211690701-006 Case: 200104616 EIN: 36-4041298 BPD: 01 Plan: 006 Letter Serial No: K208222a CHICAGO TRUST CO Contact Person: Ms. Arrington 50-00197 171 NORTH CLARK STREET Telephone Number: (202) 283-8811 CHICAGO, IL 60601 In Reference to: T:EP:RA:ICU Date: 08/30/2001 Dear Applicant: In our opinion, the form of the plan identified above is acceptable under section 401 of the Internal Revenue Code for use by employers for the benefit of their employees. This opinion relates only to the acceptability of the form of the plan under the Internal Revenue Code. It is not an opinion of the effect of other Federal or local statutes. You must furnish a copy of this letter to each employer who adopts this plan. You are also required to send a copy of the approved form of the plan, any approved amendments and related documents to Employee Plans Determinations in Cincinnati at the address specified in section 9.11 of Rev. Proc. 2000-20, 2000-6 I.R.S. 553. This letter considers the changes in qualifications requirements made by the Uruguay Round Agreements Act (GATT), Pub. L. 103-465, the Small Business Job Protection Act of 1996, Pub. L. 104-188 the Uniformed Services Employment and Reemployment Rights Act of 1994, Pub. L. 103-353, the Taxpayer Relief Act of 1997, Pub. L. 105-34, the Internal Revenue Service Restructuring and Reform Act of 1998, Pub. L. 105-206 and the Community Renewal Tax Relief Act of 2000, Pub. L. 106-554. These laws are referred to collectively as GUST. Our opinion on the acceptability of the form of the plan is not a ruling determination as to whether an employer's plan qualifies under Code section 401(a). However, an employer that adopts this plan may rely on this letter with respect to the qualification of its plan under Code section 401(a), except as provided below, provided the eligibility requirements and contribution or benefit provisions are not more favorable for highly compensated employees than for other employees. The terms of the plan must be followed in operation. Except as stated below, Employee Plans Determinations will not issue a determination letter with respect to this plan. Our opinion does not apply for purposes of Code section 401(a)(10)(B) and section 401(a)(16) if an employer ever maintained another qualified plan for one or more employees who are covered by this plan, other than a specified paired plan within the meaning of section 4.13 of Rev. Proc. 2000-20, 2000-6 I.R.B. 553. For this purpose, the employer will not be considered to have maintained another plan merely because the employer has maintained another defined contribution plan(s), provided such other plan(s) has been terminated prior to the effective date of this plan and no annual additions have been credited to the account of any participant under such other plan(s) as of any date within the limitation year of this plan. Likewise, if this plan is first effective on or after the effective date of the repeal of Code section 425(a), the employer will not be considered to have maintained another plan merely because the employer has maintained a defined benefit plan(s), provided the defined benefit plan(s) has been terminated prior to the effective date of this plan. Our opinion also does not apply for purposes of Code section 401(a)(16) if, after December 31, 1985, the employer maintains a welfare benefit fund defined in Code section 419(e), which provides postretirement medical benefits allocated to separate accounts for key employees as defined in Code section 419A(d)(3). An employer that adopts this plan may not rely on this opinion letter with respect to: (1) whether any amendment or series of amendments to the plan satisfies the nondiscrimination requirements of section 1.401(a)(4)-5(a) of the regulations, except with respect to plan amendments granting past service that meet the safe harbor described in section 1.401(a)(4)-5(a) (5) and are not part of a pattern of amendments that significantly discriminates in favor of highly compensated employees: or (2) whether the plan satisfies the effective availability requirement of section 1.401(a)(4)-4(c) of the regulations with respect to any benefit, right or feature.

CHICAGO TRUST CO PPN: 50211690701-006 Page 2 An employer that adopts this plan as an amendment to a plan other than a standardized plan may not rely on this opinion letter with respect to whether a benefit, right or other feature that is prospectively eliminated satisfies the current availability requirements of section 1.401(a)-4 of the regulations. An employer that elects to continue to apply the pre-GUST family aggregation rules in years beginning after December 31, 1996, or the combined plan limit of section 415(e) in years beginning after December 31, 1999, will not be able to rely on the opinion letter without a determination letter. The employer may request a determination (1) as to whether the plan, considered with all related qualified plans and, if appropriate, welfare benefit funds, satisfies the requirements of Code section 401(a)(16) as to limitations on benefits and contributions in Code section 415 and the requirements of Code section 401(a)(10)(B) as to the top-heavy plan requirements in Code section 416; (2) regarding the nondiscriminatory effect of grants of past service; (3) with respect to whether a prospectively eliminated benefit, right or feature satisfies the current availability requirements; and (4) with respect to the continued application of the pre-GUST family aggregation rules in years beginning after December 31, 1996, or the combined plan limit of section 415(e) in years beginning after December 31, 1999. The employer may request a determination letter by filing an application with Employee Plans Determinations on Form 5307, Application for Determination for Adopters of Master or Prototype or Volume Submitter Plans. If you, the master or prototype sponsor, have any questions concerning the IRS processing of this case, please call the above telephone number. This number is only for use of the sponsor. Individual participants and/or adopting employers with questions concerning the plan should contact the master or prototype sponsor.

These services are described in its separate Administrative Services Agreement with the Employer. ABN AMRO does not undertake as part of its services to review the entire Plan or its underlying documentation, except to the extent necessary in order to place the current terms of the Employer's Plan onto the form of the Master Retirement Plan, based on information provided by the Employer or its outside advisors. Whether or not ABN AMRO notes a potential defect the Employer's Plan, it does not assume responsibility for correcting any defect in the Plan. While ABN AMRO will notify the Employer to the extent required by IRS procedures, it does not have the ability nor does it undertake to evaluate such a defect at the level and detail needed to determine if the Employer should make a request or take other action under IRS procedures (currently known as EPCRS). Only the Employer, the Plan Sponsor, or their legal representatives are permitted to take action under EPCRS. The Employer should consider, with the advice of counsel or another qualified plan advisor, what action may be appropriate, either under EPCRS or otherwise, to deal with any potential Plan defect or other feature that the Employer knows or has notice of with respect to its Plan document or operation, in order to ensure the Plan's qualification under applicable laws. The Employer (or any Participating Employer) understands that the adoption of the Plan under the form of the Master Retirement Plan, of which this Appendix C is hereby made a part, has significant legal and tax consequences, and that it has consulted with its attorney prior to signing the Adoption Agreement. ABN AMRO assumes no responsibility or liability for the Employer's decision to so adopt or not adopt the Plan. The Employer further acknowledges that failure to amend and restate its Plan for the laws together known as GUST by the required deadline established by the IRS, will cause the Plan to be disqualified, and that the Employer is responsible for timely providing ABN AMRO with all information necessary to complete the Master Retirement Plan as described above. By signing the accompanying Adoption Agreement, and thus placing its Plan on the form of Master Retirement Plan (or by signing a Participation Agreement as a Participating Employer in the Plan), the Employer acknowledges, accepts and agrees to this Appendix C as presented above.

ARTICLE X MODIFICATION OF TOP-HEAVY RULES 10.1 Effective date. This Article shall apply for purposes of determining whether the plan is a top-heavy plan under Section 416(g) of the Code for plan years beginning after December 31, 2001, and whether the plan satisfies the minimum benefits requirements of Section 416(c) of the Code for such years. This Article amends the top-heavy provisions of the plan. 10.2 Determination of top-heavy status. 10.2.1 Key employee. Key employee means any employee or former employee (including any deceased employee) who at any time during the plan year that includes the determination date was an officer of the employer having annual compensation greater than $130,000 (as adjusted under Section 416(i)(1) of the Code for plan years beginning after December 31, 2002), a 5-percent owner of the employer, or a 1-percent owner of the employer having annual compensation of more than $150,000. For this purpose, annual compensation means compensation within the meaning of Section 415(c)(3) of the Code. The determination of who is a key employee will be made in accordance with Section 416(i)(1) of the Code and the applicable regulations and other guidance of general applicability issued thereunder. 10.2.2 Determination of present values and amounts. This Section 10.2.2 shall apply for purposes of determining the present values of accrued benefits and the amounts of account balances of employees as of the determination date. a. Distributions during year ending on the determination date. The present values of accrued benefits and the amounts of account balances of an employee as of the determination date shall be increased by the distributions made with respect to the employee under the plan and any plan aggregated with the plan under Section 416(g)(2) of the Code during the 1-year period ending on the determination date. The preceding sentence shall also apply to distributions under a terminated plan which, had it not been terminated, would have been aggregated with the plan under Section 416(g)(2)(A)(i) of the Code. In the case of a distribution made for a reason other than separation from service, death, or disability, this provision shall be applied by substituting "5-year period" for "1-year period." b. Employees not performing services during year ending on the determination date. The accrued benefits and accounts of any individual who has not performed services for the employer during the 1-year period ending on the determination date shall not be taken into account. 10.3 Minimum benefits. 10.3.1 Matching contributions. Employer matching contributions shall be taken into account for purposes of satisfying the minimum contribution requirements of Section 416(c)(2) of the Code and the plan. The preceding sentence shall apply with respect to matching contributions under the plan or, if the plan provides that the minimum contribution requirement shall be met in another plan, such other plan. Employer matching contributions that are used to satisfy the minimum contribution requirements shall be treated as matching contributions for purposes of the actual contribution percentage test and other requirements of Section 401(m) of the Code. 10.3.2 Contributions under other plans. The employer may provide, in an addendum to this amendment, that the minimum benefit requirement shall be met in another plan (including another plan that consists solely of a cash or deferred arrangement which meets the requirements of Section 401(k)(12) of the Code and matching contributions with respect to which the requirements of Section 401(m)(11) of the Code are met). The addendum should include the name of the other plan, the minimum benefit that will be provided under such other plan, and the employees who will receive the minimum benefit under such other plan.

The definition of eligible retirement plan shall also apply in the case of a distribution to a surviving spouse, or to a spouse or former spouse who is the alternate payee under a qualified domestic (C) Copyright 2001 ABN AMRO Trust Services Company 11/02 4

EGTRRA - SPONSOR CREDIT ACCEPTANCE CORPORATION 401(k) PROFIT SHARING PLAN AND TRUST relation order, as defined in Section 414(p) of the Code. 11.3 Modification of definition of eligible rollover distribution to exclude hardship distributions. For purposes of the direct rollover provisions of the plan, any amount that is distributed on account of hardship shall not be an eligible rollover distribution and the distributee may not elect to have any portion of such a distribution paid directly to an eligible retirement plan. 11.4 Modification of definition of eligible rollover distribution to include after-tax employee contributions. For purposes of the direct rollover provisions in the plan, a portion of a distribution shall not fail to be an eligible rollover distribution merely because the portion consists of after-tax employee contributions which are not includible in gross income. However, such portion may be transferred only to an individual retirement account or annuity described in Section 408(a) or (b) of the Code, or to a qualified defined contribution plan described in Section 401(a) or 403(a) of the Code that agrees to separately account for amounts so transferred, including separately accounting for the portion of such distribution which is includible in gross income and the portion of such distribution which is not so includible. ARTICLE XII ROLLOVERS FROM OTHER PLANS Rollovers from other plans. The employer, operationally and on a nondiscriminatory basis, may limit the source of rollover contributions that may be accepted by this plan. ARTICLE XIII REPEAL OF MULTIPLE USE TEST Repeal of Multiple Use Test. The multiple use test described in Treasury Regulation Section 1.401(m)-2 and the plan shall not apply for plan years beginning after December 31, 2001.

If this is a SIMPLE 401(k) plan, then except to the extent permitted under Article VI of this amendment and Section 414(v) of the Code, if applicable, the maximum salary reduction contribution that can be made to this plan is the amount determined under Section 408(p)(2)(A)(ii) of the Code for the calendar year. ARTICLE XV SAFE HARBOR PLAN PROVISIONS Modification of Top-Heavy Rules. The top-heavy requirements of Section 416 of the Code and the plan shall not apply in any year beginning after December 31, 2001, in which the plan consists solely of a cash or deferred arrangement which meets the requirements of Section 401(k)(12) of the Code and matching contributions with respect to which the requirements of Section 401(m)(11) of the Code are met. ARTICLE XVI DISTRIBUTION UPON SEVERANCE OF EMPLOYMENT 16.1 Effective date. This Article shall apply for distributions and transactions made after December 31, 2001, regardless of when the severance of employment occurred. 16.2 New distributable event. A participant's elective deferrals, qualified nonelective contributions, qualified matching contributions, and earnings attributable to these contributions shall be distributed on account of the participant's severance from employment. However, such a distribution shall be subject to the other provisions of the plan regarding distributions, other than provisions that require a separation from service before such amounts may be distributed.

EXHIBIT 99.2 CREDIT ACCEPTANCE CORPORATION 401(k) PLAN AND TRUST ADMINISTRATIVE RULES FOR INVESTMENTS IN EMPLOYER STOCK Credit Acceptance Corporation (the "Plan Sponsor") interprets the term "Employer Stock" as used in the Credit Acceptance Corporation 401(k) Plan to include its common stock as long as such stock is registered under Section 12 of the Securities Exchange Act of 1934 and publicly traded. Participants in the Credit Acceptance Corporation 401(k) Plan and Trust (the "Plan") may receive matching contributions in Employer Stock and may direct the investment of contributions made to their Plan accounts in Employer Stock. Set forth below are the administrative rules for investments in Employer Stock under the Plan. I. SECURITIES TRANSACTIONS (a) EMPLOYER STOCK FUND. The Employer Stock Fund is an investment fund, the assets of which shall be invested primarily in Employer Stock, and a portion of the assets of the Employer Stock Fund shall be invested in cash or cash equivalents (which may include a money market fund that is managed by a subsidiary or affiliate of the Trustee). The Employer Stock Fund shall be divided into units, each representing a proportionate share of Employer Stock and cash (or cash equivalents) held within the Employer Stock Fund. The Trustee shall cause to be maintained an Employer Stock Fund account for each participant. Participants who have directed that assets held in their Plan account be invested in the Employer Stock Fund (or who have received an Employer matching contribution that has been invested in the Employer Stock Fund) shall be allocated units in the Employer Stock Fund, representing the value of each such participant's interest in the Employer Stock Fund. As promptly as practicable after the close of each quarter of a calendar year, the Trustee shall cause a statement to be mailed or delivered to each participant setting forth the participant's account balance as of the close of such quarter. (b) VALUATION OF EMPLOYER STOCK FUND. On each "Valuation Date" (as defined in the Plan), the Trustee shall value the total assets held within the Employer Stock Fund, including the value of the Employer Stock and cash (or cash equivalent) portion of the Employer Stock Fund with accrued but not yet payable dividends or earnings) at their fair market value. The fair market value of the Employer Stock Fund shall be determined by using the closing price of Employer Stock on the Nasdaq Stock Market ("NSM") on the most recent trading day, as reported in The Wall Street Journal, which shall be the price utilized in the valuation of the Employer Stock Fund for all purposes. A "trading day" shall mean any day on which the Trustee is open for business and is able to transact trades involving Employer Stock as a Plan investment. The close of a trading day shall be the time of the close of the New York Stock Exchange. In the event that the Trustee is incapable of processing trades involving Employer Stock for any reason whatsoever, or in the event trading in Employer Stock is suspended for any reason whatsoever, the close of the trading day shall be the last time at which transactions involving Employer Stock may be processed on any such day. The

Trustee shall determine a per unit value ("NAV") by dividing the total value of the Employer Stock Fund by the total number of units held by Plan participants. The Trustee shall use the NAV in processing Plan transactions, including but not limited to Employer Stock Fund transfers, participant loans and distributions. The Trustee may follow directions from the Plan Administrator to deviate from the purchase and sales procedures set forth herein, provided that such direction is made in writing by the Plan Administrator. (c) PROCESSING TRANSACTIONS. To process participant-directed transactions involving the Employer Stock Fund (whether involving purchases, sales, or a combination of both) that are received by the Trustee, the Trustee will take the following steps: (i) The Trustee shall aggregate all participant-directed transactions for any trading day resulting in a purchase of units of the Employer Stock Fund and shall aggregate all participant-directed transactions for such trading day resulting in a sale of or divestment of units of the Employer Stock Fund, and then shall net together the aggregated purchases and sales for such trading day to arrive at a net purchase or sale of units of the Fund. (ii) If a net sale of units is required after all the aggregated purchases and sales for a trading day have been netted, the Trustee shall determine the total value of the net sale, using the NAV determined as set forth above, and shall withdraw from the Employer Stock Fund sufficient cash or cash equivalents to reflect the total value of the net sale. The cash withdrawn shall then be applied for such purposes as may be required to complete the transactions for that trading day. In the event there is insufficient cash or cash equivalents in the Employer Stock Fund to process the net sale, the Trustee shall utilize all available cash or cash equivalents held in the Employer Stock Fund to transact a portion of the net sale. In using the cash or cash equivalents for offsetting transactions, the Trustee shall apply the cash proportionately across the transactions that would have been effected on such trading day but for the insufficient cash and cash equivalents. Any transactions that cannot occur as a result of insufficient cash or cash equivalents to provide liquidity shall be suspended until such time as the Trustee may sell shares of Employer Stock. When the sales of Employer Stock have settled, the Trustee shall proceed to process those suspended transactions, at the then current NAV (and market prices). (iii) If a net purchase of units is required after all the aggregated purchases and sales for a trading day have been netted, the Trustee shall deposit in the Employer Stock Fund such cash as represents the total value of the net purchase, and shall account for the deposited cash in ascertaining the Employer Stock Fund NAV as of the close of the next trading day. (iv) The Trustee shall generally execute market transactions as soon as practicable after the effective date of the participant direction. The Trustee shall use reasonable efforts to obtain the most favorable price. If the Trustee is unable to make sufficient market purchases on the effective date of the participant-directed transaction or within one trading day thereafter, the unused funds shall be temporarily invested in the Trustee's fixed income investment option until Employer Stock can be so purchased. The Trustee shall use its best efforts to effectuate trades involving Employer Stock in a manner consistent with its obligations under ERISA. Subject to compliance

with its obligations under ERISA, in processing transactions involving Employer Stock, the Trustee shall have sole discretion with respect to the broker or market maker through which the purchase or sale shall occur and whether to execute the purchase or sale in a single or multiple transactions. (v) Notwithstanding the steps described above, the Plan Sponsor may instruct the Trustee to take other actions. However, the Trustee shall only follow those instructions which are proper and consistent with the Trustee's standard operating procedures, and proper and consistent with ERISA and any other applicable laws. (vi) If Employer Stock is acquired from, or sold to, a "party-in-interest" as defined in ERISA section 3(14), no commission may be paid. (d) CASH POSITION. The Trustee shall monitor the amount of cash contained within the Employer Stock Fund and provide information to the Plan Sponsor. The Plan Sponsor shall determine the amount of cash that is necessary to provide sufficient liquidity for the Trustee to process Plan transactions. In order to accomplish this, the Trustee shall review and report the proportion of cash to Employer Stock held within the Employer Stock Fund no less frequently than once each month. In the event the cash portion of the Fund is not deemed to provide adequate liquidity, the Trustee shall sell sufficient shares of Employer Stock as are necessary to bring the cash portion of the Fund to an acceptable level. Purchases and sales shall be made in accordance with the instructions in paragraph (c) above. Notwithstanding the actions described in this subsection, as a Plan Fiduciary, the Plan Sponsor shall annually review the cash position of the Employer Stock Fund to confirm its appropriateness based on Plan transactions and activities. II. RIGHTS, WARRANTS, OR OPTIONS Stock rights (including warrants and options) issued with respect to Employer Stock held in the Plan shall be sold by the Trustee on behalf of participants and the proceeds shall be invested in the Employer Stock Fund. III. REINVESTMENT OF DIVIDENDS Cash dividends to be paid to the Employer Stock Fund shall be accrued within the Employer Stock Fund on the Ex-Date based on the holdings as of that date. On the Ex-Date the Employer Stock Fund's valuation shall reflect all dividends paid. IV. EXTRAORDINARY TRANSACTION CONSIDERATION (a) IN GENERAL. In the event that the Plan Sponsor is involved in any merger, consolidation, reorganization, tender offer or other transaction in which shareholders of the Plan Sponsor are entitled to elect the form of consideration to be received for their shares or whether to accept a tender offer, each Plan participant shall be entitled to make such election with respect to all shares (vested and unvested) allocated to his or her account. The election shall be in accordance with the procedures described below.

(b) VOTING AND TENDER OFFERS. Notwithstanding any other provision of the Plan or Trust Agreement, the provisions of this Section shall govern the voting and tendering of Employer Stock. The Employer, after consultation with the Trustee and the Stock Transfer Agent, shall provide and pay for all printing, mailing, tabulation and other costs associated with the voting and tendering of Employer Stock. To the extent that any action is required of the Trustee pursuant to the terms of this Section, the Trustee may delegate such action to be performed by its designated agent. (c) VOTING RIGHTS. (i) Each Plan participant (or, in the event of a participant's death, the participant's beneficiary) shall have the right to direct the Trustee as to the manner in which shares of Employer Stock held in the participant's account (vested and unvested) are to be voted (or not voted) on each matter brought before an annual or special meeting of the Plan Sponsor's shareholders. The issuer of Employer Stock shall notify the Trustee and the Credit Acceptance Corporation Stock Transfer Agent (the "Stock Transfer Agent") at the same time as it notifies NSM of the record date for the upcoming meeting . The Stock Transfer Agent shall cause a copy of all proxy solicitation materials to be sent to Plan participants and the Trustee. If requested by the Trustee, the Stock Transfer Agent shall certify to the Trustee that the aforementioned materials represent the same information that is being distributed to non-participant shareholders of Employer Stock. The Stock Transfer Agent shall prepare a voting instruction form and shall provide a copy of all proxy solicitation materials to be sent to each participant with the foregoing voting instruction form to be returned to the Stock Transfer Agent or its designee. The form shall show the number of full and fractional shares of Employer Stock credited to the participant's Accounts held in the Stock Fund. (ii) The shares representing a participant's interest in the Employer Stock Fund shall be the number of shares (including, to the extent practicable, fractional shares), which bears the same ratio to the total number of shares held in the Employer Stock Fund as the dollar amount of such participant's interest in the Employer Stock Fund bears to the total value of the Employer Stock Fund, determined as of the most recent date for which a valuation has been established on or before the record date. (iii) Upon timely receipt of the election form, the Stock Transfer Agent shall forward the information from the executed election form to the Trustee, and the Trustee shall vote such shares in the manner directed, unless required otherwise by ERISA. Except as otherwise required by law, the instructions received by the Stock Transfer Agent and the Trustee concerning any individual participant shall be held by the Stock Transfer Agent and the Trustee in strict confidence, which shall not be divulged or released to any person, including officers or employees of the Plan Sponsor or any Affiliate. To the extent permitted by law, the Trustee shall vote all shares of Employer Stock for which it has not received instructions (including any shares representing a participant's interest in the Employer Stock Fund for which no instructions are received), in the same proportion as shares for which instructions are received.

(d) TENDER OFFERS. (i) Each Plan participant (or, in the event of a participant's death, the participant's beneficiary) shall have the right to direct the Trustee as to the manner in which shares of Employer Stock held in the participant's account (vested and unvested) are to be tendered (or not tendered) in the event of a tender offer. The Plan Administrator shall timely notify the Stock Transfer Agent and the Trustee in advance of the intended tender date and shall cause a copy of all materials to be sent to the Trustee. The Stock Transfer Agent shall certify to the Trustee that the aforementioned materials represent the same information that is to be distributed to non-participant shareholders of Employer Stock. Based on these materials and after consultation with the Plan Administrator, the Stock Transfer Agent shall prepare a tender instruction form and shall provide a copy of all tender materials to be sent to each Plan participant, together with the foregoing tender instruction form, to be returned to the Stock Transfer Agent, who shall forward the information to the Trustee or its designee. The tender instruction form shall show the number of full and fractional shares of Employer Stock that reflect the participant's interest in the Employer Stock Fund. (ii) The shares representing a participant's interest in the Employer Stock Fund shall be the number of shares (including, to the extent practicable, fractional shares), which bears the same ratio to the total number of shares held in the Employer Stock Fund as the dollar amount of such participant's interest in the Employer Stock Fund bears to the total value of the Employer Stock Fund, determined as of the most recent date for which a valuation has been established on or before the record date. Upon timely receipt of the executed election form information from the Stock Transfer Agent, the Trustee shall tender or not tender such shares in the matter directed, unless required otherwise by ERISA. Except as otherwise required by law, the instructions received by the Stock Transfer Agent and the Trustee concerning any individual participant shall be held by the Stock Transfer Agent and the Trustee in strict confidence and shall not be divulged or released to any person, including officers or employees of the Plan Sponsor or any Affiliate. To the extent permitted by law, the Trustee shall tender or not tender all shares of Employer Stock for which it has not received instructions (including any shares representing a participant's interest in the Employer Stock Fund for which no instructions are received), in the same proportion as shares for which instructions are received. V. SECURITIES LAW REPORTS The Plan Administrator shall be responsible for filing all Plan reports required under Federal or state securities laws with respect to the Trust's ownership of Employer Stock, including, without limitation, any reports required under Section 13 or 16 of the Securities Exchange Act of 1934, and shall immediately notify the Trustee in writing of any requirement to stop purchases or sales of Employer Stock pending the filing of any report.
