It has taken all action necessary to authorize the execution and delivery by it of the VG Funding Sale Agreement and this Agreement, and the VG Funding Sale Agreement and this Agreement have been executed and delivered by one of its officers who is duly authorized to execute and deliver the same on its behalf.

Neither the execution nor the delivery by it of the VG Funding Sale Agreement or this Agreement, nor the consummation by it of the transactions contemplated thereby or hereby nor compliance by it with any of the terms or provisions thereof or hereof will contravene any Federal or Delaware state law, governmental rule or regulation governing the banking or trust powers of the VG Funding Trustee or any judgment or order binding on it, or constitute any default under its charter documents or by-laws or any indenture, mortgage, contract, agreement or instrument to which it is a party or by which any of its properties may be bound.

ARTICLE VIII

Successor VG Funding Trustees

SECTION 8.1 Eligibility Requirements for VG Funding Trustee. The VG Funding Trustee shall at all times be a corporation or banking association being authorized to exercise corporate trust powers and hold legal title to the Interim Trust Loans. In case at any time the VG Funding Trustee shall cease to be eligible in accordance with the provisions of this Section, the VG Funding Trustee shall resign immediately in the manner and with the effect specified in Section 8.2.

SECTION 8.2 Resignation or Removal of VG Funding Trustee. The VG Funding Trustee may at any time resign and be discharged from the trust hereby created by giving written notice thereof to VG Funding. Upon receiving such notice of resignation, VG Funding shall promptly appoint a successor VG Funding Trustee meeting the eligibility requirements of Section 8.1 by written instrument, in duplicate, one copy of which instrument shall be delivered to the resigning VG Funding Trustee and one copy to the successor VG Funding Trustee. If no successor VG Funding Trustee shall have been so appointed and have accepted appointment within 30 days after the giving of such notice of resignation, the resigning VG Funding Trustee may petition any court of competent jurisdiction for the appointment of a successor VG Funding Trustee; provided, however, that such right to appoint or to petition for the appointment of any such successor shall in no event relieve the resigning VG Funding Trustee from any obligations otherwise imposed on it under this Agreement or the VG Funding Sale Agreement until such successor has in fact assumed such appointment.

If at any time the VG Funding Trustee shall cease to be or shall be likely to cease to be eligible in accordance with the provisions of Section 8.1 and shall fail to resign after written request therefor by VG Funding, then VG Funding may remove the VG Funding Trustee. If VG Funding shall remove the VG Funding Trustee under the authority of the immediately preceding sentence, VG Funding shall promptly appoint a successor VG Funding Trustee by written instrument, in duplicate, one copy of which instrument shall be delivered to the outgoing VG Funding Trustee so removed and one copy to the successor VG Funding Trustee together with payment of all fees owed to the outgoing VG Funding Trustee.

Any resignation or removal of the VG Funding Trustee and appointment of a successor VG Funding Trustee pursuant to any of the provisions of this Section shall not become effective until acceptance of appointment by the successor VG Funding Trustee pursuant to Section 8.3 and payment of all fees and expenses owed to the outgoing VG Funding Trustee.

SECTION 8.3 Successor VG Funding Trustee. Any successor VG Funding Trustee appointed pursuant to Section 8.2 shall execute, acknowledge and deliver to VG Funding and to its predecessor VG Funding Trustee an instrument accepting such appointment under this Agreement, and thereupon the resignation or removal of the predecessor VG Funding Trustee shall become effective and such successor VG Funding Trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor under this Agreement, with like effect as if originally named as VG Funding Trustee. The predecessor VG Funding Trustee shall upon payment of its fees and expenses deliver to the successor VG Funding Trustee all documents, statements, moneys and properties held by it under this Agreement and shall assign, if permissible, to the successor VG Funding Trustee any lender identification number obtained from the Department with respect to the Interim Trust Loans; and VG Funding and the predecessor VG Funding Trustee shall execute and deliver such instruments and do such other things as may reasonably be required for fully and certainly vesting and confirming in the successor VG Funding Trustee all such rights, powers, duties and obligations.

No successor VG Funding Trustee shall accept such appointment as provided in this Section unless at the time of such acceptance such successor VG Funding Trustee shall be eligible pursuant to Section 8.1.

SECTION 8.4 Merger or Consolidation of VG Funding Trustee. Any corporation into which the VG Funding Trustee may be merged or converted or with which it may be consolidated, or any corporation or banking association resulting from any merger, conversion or consolidation to which the VG Funding Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the VG Funding Trustee, shall, without the execution or filing of any instrument or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding, be the successor of the VG Funding Trustee hereunder; provided that such corporation or banking association shall be eligible pursuant to Section 8.1.

Prior to the execution of any amendment to this Agreement, the VG Funding Trustee shall be entitled to receive and rely upon an Opinion of Counsel stating that the execution of such amendment is authorized or permitted by this Agreement.

SECTION 9.4 Separate Counterparts. This Agreement may be executed by the parties hereto in separate counterparts, each of which when so executed and delivered shall be an original, but all such counterparts shall together constitute but one and the same instrument.

SECTION 9.5 Successors and Assigns. All covenants and agreements contained herein shall be binding upon and to the benefit of, VG Funding and its successors and the VG Funding Trustee and its successors, all as herein provided.
