NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

“Repurchases of Aged Receivables and EPS Receivables; Retransfers of Incipient Written-Off Receivables. In the event that the Funding Purchaser, pursuant to Section 5.1 of the Receivables Purchase Agreement, repurchases from the Purchaser Aged Receivables or EPS Receivables, then without further action on the part of T-Mobile PCS Holdings or the Funding Purchaser, each such Aged Receivable or EPS Receivable shall be immediately thereafter automatically repurchased by T-Mobile PCS Holdings (a) in the case of Aged Receivables (which are not EPS Receivables) at a repurchase price equal to the original Purchase Price for such Receivable (an amount equal to (i) the Outstanding Balance of such Purchased Receivable on the date of repurchase minus (ii) the Discount with respect to such Purchased Receivable) and (b) in the case of EPS Receivables at a repurchase price equal to (i) the EPS Fair Value Percentage of (ii) the Outstanding Balance of such Purchased Receivable on the date of repurchase. Such repurchase prices shall be paid by T-Mobile PCS Holdings in cash to the Funding Purchaser. In the event that the Funding Purchaser, pursuant to Section 5.1(a) of the Receivables Purchase Agreement, repurchases from the Purchaser Receivables that immediately prior to such repurchase will become Written-Off Receivables (each such Receivable, an “Incipient Written-Off Receivable”), then without further action on the part of

T-Mobile PCS Holdings or the Funding Purchaser, each such Incipient Written-Off Receivable shall be immediately thereafter automatically retransferred to T-Mobile PCS Holdings. All such repurchases and retransfers shall be made without recourse to, and without warranty of any kind by, the Funding Purchaser, and all representations and warranties are hereby expressly disclaimed.”

IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be executed by their respective officers thereunto duly authorized as of the date written above.

ACKNOWLEDGED AND ACCEPTED:
