This Agreement and the transmittal of the electronic listing of the Receivables in the manner described herein shall constitute T-Mobile PCS’s authentication of a record describing the Receivables and the Related Rights so conveyed for purposes of applicable law, including Article 9 of the Relevant UCC in the applicable jurisdictions and law and regulations relating to electronic signatures.

(b)The sales, transfers, assignments, set-overs and conveyances described above shall be made in consideration of the Purchaser’s payment, in respect of each such Purchased Assets, of a purchase price (the “RSCA Purchase Price”) therefor in an amount equal to the Outstanding Balance of each Receivable as of the Purchase Date or any other amount that is mutually agreed upon by T-Mobile PCS and the Purchaser as of the Purchase Date; provided that such RSCA Purchase Price shall be at least equal to the fair market value thereof.

(c)The RSCA Purchase Price for Purchased Assets purchased by the Purchaser from T-Mobile PCS shall be paid by the Purchaser on each Purchase Date as follows:

(i)to the extent available for such purpose, in cash held by the Purchaser;

(ii)the Deferred Payment Amount; and

(d)The foregoing assignments, transfers, set-overs, and conveyances do not constitute and are not intended to result in a creation or an assumption by the Purchaser of any obligation of T-Mobile PCS or the applicable Originator in connection with the Purchased Assets being so assigned or conveyed, or any agreement or instrument relating thereto, including, without limitation, (i) any obligation to any Obligor and (ii) any taxes, fees, or other charges imposed by any Governmental Authority.

(e)The parties hereto intend and agree that any conveyance hereunder of T-Mobile PCS’s right, title, and interest in and to any Purchased Assets is, and is intended to be, an absolute conveyance and transfer of ownership of such Purchased Assets, conveying good title and ownership, not a transfer to secure a loan or other payment obligation or any transfer subject to any right of redemption, and that such Purchased Assets shall not be part of T-Mobile PCS’s estate in the event of the filing of a bankruptcy petition or other action by or against any such Person under any Insolvency Law. In the event, however, that, notwithstanding such intent and agreement, any conveyance hereunder shall be determined by a court of competent jurisdiction not to be a conveyance of ownership, T-Mobile PCS hereby grants and assigns to the Purchaser a perfected first priority security interest in (i) such Purchased Assets and (ii) all income from and proceeds of the foregoing, and this Agreement shall constitute a security agreement under applicable law, securing the obligations of T-Mobile PCS to the Purchaser hereunder, including the obligation to transfer absolute ownership of such Purchased Assets. If such conveyance is deemed to be the mere granting of a security interest to secure an obligation, the Purchaser may, to secure the Purchaser’s obligations under the Master Receivables Purchase Agreement (to the extent that the transfer of Transferred Assets thereunder is deemed to be a mere granting of security interest to secure an obligation), repledge and reassign (i) all or a portion of the Purchased Assets thereunder pledged to the Purchaser and not released or reconveyed from the security interest of this Agreement at the time of such pledge and assignment and (ii) all income from and proceeds of the foregoing. Such repledge and reassignment may be made by the Purchaser with or without a repledge and reassignment by T-Mobile PCS under this Agreement, and without further notice to or acknowledgment from T-Mobile PCS or any other Person.

(f)To the extent that T-Mobile PCS retains any interest in the Purchased Assets, T-Mobile PCS hereby grants to the Administrative Agent (for the benefit of the Owners) a security interest in all of T-Mobile PCS’s right, title and interest, whether now owned or hereafter acquired, in, to and under the Purchased Assets, to secure the performance of all of the obligations of T-Mobile PCS hereunder and under the Master Receivables Purchase Agreement. With respect to such security interest and such collateral, the Administrative Agent shall have all of the rights that it has under the Master Receivables Purchase Agreement. The Administrative Agent shall also have all of the rights of a secured creditor under the Relevant UCC.

(g)T-Mobile PCS shall:

(i)on or prior to (x) the Amendment and Restatement Closing Date, with respect to the Receivables being sold, contributed or otherwise conveyed on such date, indicate in its books and records and on the appropriate computer files that such Receivables and the related other Purchased Assets have been sold, contributed or otherwise conveyed to the Administrative Agent (for the benefit of the Owners) in accordance with the Master Receivables Purchase Agreement and (y) each Addition Date, with respect to the additional Receivables being sold, contributed or otherwise conveyed on such date, indicate in its books and records and on the appropriate computer files that such additional Receivables and the related other Purchased Assets have been sold, contributed or otherwise conveyed to the Purchaser in accordance with this Agreement;

(ii)on or prior to the Amendment and Restatement Closing Date and on each Determination Date thereafter, cause the Servicer to deliver to the Purchaser the updated Receivables Schedule; and

(iii)on each Funding Date following the Amendment and Restatement Closing Date, cause the Servicer to deliver to the Purchaser the Bringdown Receivables File.

(h)Each Receivables Schedule and Bringdown Receivables File delivered to the Purchaser by T-Mobile PCS or the Servicer on its behalf shall be deemed to be “signed” for purposes of the Relevant UCC and an authenticated security agreement for purposes of Sections 9-102 and 9-103 of the Relevant UCC.

(i)T-Mobile PCS represents, warrants and agrees that transmission of each Bringdown Receivables File and each Receivables Schedule consisting of, including or accompanied by an electronic file (which may be a PDF or the insertion of the relevant language and names in a Word, Excel or other electronic document) and transmitted either (a) from a Designated Email Address or (b) by a Servicing Officer through a virtual data room (including but not limited to Intralinks) acceptable to the Administrative Agent, shall be evidence of its present intent to adopt or accept such record as the authentication of a security agreement for purposes of Sections 9-102 and 9-203 of any Relevant UCC.

Section 2.03Conditions Relating to Sales of Receivables. (a) T-Mobile PCS shall not sell, transfer, assign or otherwise convey Receivables to the Purchaser unless on the applicable Purchase Date the following conditions are satisfied with respect to the Receivables to be sold, transferred, assigned and otherwise conveyed on such date:

(ii)T-Mobile PCS shall have filed on or prior to the applicable Purchase Date, as required by Section 4.01, the financing statement(s), naming T-Mobile PCS, as seller, and the Purchaser, as purchaser, with respect to the Purchased Assets, in such a manner and in such jurisdictions as are necessary to perfect the transfer of T-Mobile PCS’s interest in the Purchased Assets to the Purchaser;

Notwithstanding any cessation of the sale to the Purchaser of additional Receivables, Receivables sold to the Purchaser prior to the occurrence of such Insolvency Event, and Collections in respect of such Receivables, shall continue to be a part of the Purchased Assets and shall be allocated and distributed to the Purchaser in accordance with the terms of this Agreement and the Master Receivables Purchase Agreement. Upon the occurrence of an

Insolvency Event, T-Mobile PCS shall promptly give notice of such Insolvency Event to the Servicer and the Administrative Agent.

(b)If any change in T-Mobile PCS’s name, type of organization or organizational jurisdiction or other action would make any financing or continuation statement or notice of ownership interest or lien filed in connection with any Related Document seriously misleading within the meaning of applicable provisions of the Relevant UCC or any title statute, or would otherwise impair the perfection of any lien contemplated hereunder or under any other Related Document, T-Mobile PCS, no later than thirty (30) days after the effective date of such change, shall file such amendments as may be required to preserve and protect the Purchaser’s interests herein and in the Purchased Assets and the Collections associated therewith.

Notwithstanding anything to the contrary stated herein, T-Mobile PCS and the Purchaser hereby agree that, except as otherwise required by applicable law, the conveyance of the Purchased Assets made hereunder

shall be treated as a loan by the Purchaser to T-Mobile PCS of the proceeds of such conveyance for U.S. federal income tax purposes and state or local income tax and transactional tax purposes.

In the event that the Purchaser, pursuant to Section 2.12 of the Master Receivables Purchase Agreement, repurchases Ineligible Receivables and other Purchased Assets from the Administrative Agent (on behalf of the Owners), such Ineligible Receivables and other Purchased Assets shall immediately thereafter be repurchased by T-Mobile PCS from the Purchaser, automatically, and without further action by the Purchaser or T-Mobile PCS, on the same date, for the same amount and on the same terms of the corresponding repurchases by the Purchaser to take place under Section 2.12 of the Master Receivables Purchase Agreement. All of the retransfers of Ineligible Receivables contemplated by this Section 5.01 shall occur without recourse to, and without warranty of any kind deemed to have been made by, the Purchaser, and all representations and warranties are hereby expressly disclaimed.

In the event that the Administrative Agent (on behalf of the Owners), pursuant to Section 2.13 of the Master Receivables Purchase Agreement, retransfers Imminent Written-Off Receivables to the Purchaser, then such Imminent Written-Off Receivables shall immediately thereafter be retransferred by the Purchaser to T-Mobile PCS, automatically, and without any further action by the Purchaser or T-Mobile PCS.

For the avoidance of doubt, such limit described in the immediately preceding sentence shall not apply to transfers from the Administrative Agent to the Purchaser pursuant to Section 2.13 of the Master Receivables Purchase Agreement.

Section 5.03[Reserved].
