Period, and the denominator of which is the aggregate Principal Balance of all Pledged Contracts as of the end of such Accounting Period, or (ii) with respect to the Managed Portfolio Contracts, the percentage equivalent of a fraction, the numerator of which is the aggregate Principal Balance of the Managed Portfolio Contracts which became Charged-Off Contracts during such Accounting Period, minus the aggregate of amounts received by the Servicer during such Accounting Period and applied to any such Managed Portfolio Contract which is a Charged-Off Contract as of the end of such Accounting Period, and the denominator of which is the aggregate Principal Balance of all Managed Portfolio Contracts as of the end of such Accounting Period.

“Delinquency Measurement Ratio” means, as of any Measurement Date, (a) with respect to the Pledged Contracts, the quotient (expressed as a percentage) of (i) the Principal Balance of the Pledged Contracts which are Delinquency Measurement Contracts as of such Measurement Date, divided by (ii) the aggregate Principal Balance of all Pledged Contracts as of such Measurement Date, or (b) with respect to the Managed Portfolio Contracts, the quotient (expressed as a percentage) of (i) the Principal Balance of all of the Managed Portfolio Contracts which are Delinquency Measurement Contracts as of such Measurement Date, divided by (ii) the aggregate Principal Balance of all Managed Portfolio Contracts as of such Measurement Date

“DTCS” means DriveTime Car Sales Company, LLC, an Arizona limited liability company, together with its successors and each wholly-owned subsidiary of DriveTime Car Sales Company, LLC, created for the purpose of originating Contracts.

which the original term to maturity exceeds sixty-eight (68) months exceeds the product of 5.00% and the aggregate Principal Balances of all Eligible Contracts at such time.

2.2 The definition of “Eligible Contract” set forth in Section 1.01 of the Loan and Servicing Agreement is hereby amended by deleting clauses (g), (i) and (uu) thereof and substituting, in lieu thereof, respectively, the following:

(g) which is not (i) a Charged-off Contract, (ii) a Contract for which the Contract Debtor is a party to a proceeding under any Debtor Relief Law which arose after the creation of such Contract (other than as a creditor or claimant), (iii) a Contract for which the Amount Financed was in excess of $30,000, or (iv) a Contract that (A) was previously a Pledged Contract and (B) was previously transferred by the Borrower in connection with a Contract Disposition Transaction and, at the time of such Contract Disposition Transaction, was a Delinquency Measurement Contract; provided that notwithstanding the foregoing, a Contract of the type described in this clause (iv) may become an Eligible Contract if it otherwise satisfies the definition thereof upon the earlier of (x) the date after such Contract Disposition Transaction on which such Contract is not a Delinquency Measurement Contract and the related Contract Debtor has made at least four (4) Scheduled Payments thereunder and (y) the date on which such Contract was not a Delinquency Measurement Contract for three (3) consecutive Accounting Periods;

(i) which (i) has an original term to maturity that is not less than twelve (12) months and does not exceed sixty-two (62) months, or such other period as may be agreed to from time to time by the Borrower and the Program Agent, provided that (x) for Receivables as to which the Contract Debtor is rated “B” the original term to maturity is not less than twelve (12) months and does not exceed sixty-eight (68) months and (y) for Receivables as to which the Contract Debtor is rated “A” the original term to maturity is not less than twelve (12) months and does not exceed seventy-two (72) months, (ii) the Schedule of Payments has equal periodic payments except for payments due during the first 90 days of the term of such Contract, and except for the final payment which may be less than the other equal payments, and the payment obligation is in United States dollars, and (iii) does not cause the weighted average (based on Principal Balances of the applicable Eligible Contracts) original term to maturity of all Eligible Contracts that are Pledged Contracts to exceed sixty-two (62) months; provided that the Pledged Contracts rendered ineligible solely pursuant to the foregoing clause (iii) shall be selected by the Borrower from the Pledged Contracts with the longest original term to maturity and only with Principal Balances required to reduce such weighted average original term to maturity of all Eligible Contracts that are Pledged Contracts to or below sixty-two (62) months; provided that any such ineligible Pledged Contract may be subsequently designated by the Borrower as an “Eligible Contract” if the eligibility of such Pledged Contract would not cause such weighted average original term to maturity of all Pledged Contracts to exceed sixty-two (62) months.

(uu) with respect to which the scheduled payments under the Contract are due at least monthly in level payments through its maturity date sufficient to fully amortize the principal balance of such Contract by its maturity date, assuming timely payment by

Obligors on simple interest Contracts, except that the payment in the first or last month of the life of the Contract may be minimally different from the level payment.
