ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

(a)  On February 10, 2006, Credit Acceptance Corporation (the "Company")
     executed Amendment No. 5, dated February 10, 2006, to the Loan and Security
     Agreement dated as of September 30, 2003, among the Company, CAC Warehouse
     Funding Corporation II, Wachovia Bank, National Association, Variable
     Funding Capital Corporation, Wachovia Capital Markets, LLC, and Systems &
     Services Technologies, Inc., as amended (the "Warehouse Facility"). The
     amendment extends the maturity date of the Warehouse Facility from February
     15, 2006 until February 9, 2007 and makes various other changes to adjust
     the determination of asset values and otherwise conform the terminology
     used in the Warehouse Facility to the Company's current method of
     accounting to keep the parties' rights constant. In addition, the amendment
     extends the date on which a refinancing of amounts due under the Warehouse
     Facility must occur and otherwise modifies the related provision so that a
     refinancing of a portion of amounts outstanding under the Warehouse
     Facility will be required within 90 days of February 10, 2006 and within
     360 days of the most recent refinancing occurring after February 10, 2006.
     The amendment is attached as Exhibit 4(f)(66) to this Form 8-K and
     incorporated herein by reference.


(b)  On February 7, 2006, the Company executed the Fourth Amended and Restated
     Credit Agreement (the "Revised Credit Agreement"), between the Company, the
     Lenders which are parties thereto from time to time (each a "Bank" and
     collectively, the "Banks"), Comerica Bank as Administrative Agent for the
     Banks, and Banc of America Securities LLC as Sole Lead Arranger and Sole
     Book Manager . The Revised Credit Agreement extends the maturity date from
     June 9, 2006 to June 20, 2008 and makes various other changes to conform
     the terminology used in the Revised Credit Agreement to the Company's
     current business and method of accounting. In addition, the Revised Credit
     Agreement increased the Borrowing Base rates from 65% of the Company's
     dealer loans receivable and purchased contract balances to 75% of such
     balances. The Revised Credit Agreement also eased the minimum tangible net
     worth and maximum debt to net worth ratio requirements and eased the
     restriction on the Company's ability to repurchase shares of its common
     stock. The Revised Credit Agreement is attached as Exhibit 4(f)(67) to this
     Form 8-K and incorporated herein by reference.



(c)  In connection with the execution of the Revised Credit Agreement, the
     Company also executed the Third Amended and Restated Security Agreement,
     dated February 7, 2006, between the Company, certain subsidiaries of the
     Company and Comerica Bank, as agent for the Banks (the "Revised Security
     Agreement"). The Revised Security Agreement makes various changes to
     conform the terminology used in the Revised Security Agreement to the
     Revised Credit Agreement but does not contain any material changes to the
     security granted by the Company and its subsidiaries. The Revised Security
     Agreement is attached as Exhibit 4(f)(68) to this Form 8-K and incorporated
     herein by reference.
