Section 2.03 Investments.

(a) The Escrow Agent is authorized and directed to invest or hold, uninvested, in cash, the Escrowed Property as directed in writing by the Company; provided, that Escrowed Property may only be invested in Eligible Escrow Investments. Absent its timely receipt of a written direction from the Company, the Escrow Agent shall have no duty to invest (or otherwise pay interest on) the Escrowed Property.

Any investment earnings and income on the Escrowed Property shall become part of the Escrowed Property, and shall be disbursed in accordance with Section 2.05 of this Escrow Agreement.

(b) The Escrow Agent is hereby authorized and directed to sell or redeem any such investments to make any payments or distributions required under this Escrow Agreement. The Escrow Agent shall have no responsibility or liability for any loss, fee, tax, penalty or other charge which may result from any investment, reinvestment, sale or liquidation of investment made pursuant to this Escrow Agreement. The Escrow Agent is hereby authorized, in making or disposing of any investment permitted by this Escrow Agreement, to deal with itself (in its individual capacity) or with one or more of its affiliates, whether it or any such affiliate is acting as agent of the Escrow Agent or for any third person or dealing as principal for its own account, provided that such dealings are fair, reasonable and in keeping with market practice. The Company acknowledges that the Escrow Agent is not providing investment supervision, recommendations or advice. The Escrow Agent shall be under no duty to afford the Escrowed Property any greater degree of care than it gives its own similar property.

Section 2.04 Income Tax Allocation and Reporting.

(a) The Company agrees that, for tax reporting purposes, all interest and other income from investment of the Escrowed Property shall, as of the end of each calendar year and to the extent required by the Internal Revenue Service, be reported as having been earned by the Company, whether or not such income was disbursed during such calendar year.

(b) Concurrently with the execution and delivery of this Escrow Agreement, the Company shall provide the Escrow Agent with certified tax identification numbers by furnishing

appropriate forms W-9 or W-8 and such other forms and documents that the Escrow Agent may request. The Company understands that if such tax reporting documentation is not provided and certified to the Escrow Agent, the Escrow Agent may be required by the Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder, to withhold a portion of any interest or other income earned on the investment of the Escrowed Property.

(c) To the extent that the Escrow Agent becomes liable for the payment of any taxes in respect of income derived from the investment of the Escrowed Property, the Escrow Agent shall satisfy such liability to the extent possible from the Escrowed Property. The Company shall indemnify, defend and hold the Escrow Agent harmless from and against any tax, late payment, interest, penalty or other cost or expense that may be assessed against the Escrow Agent on or with respect to the Escrowed Property and the investment thereof unless such tax, late payment, interest, penalty or other expense was directly caused by the gross negligence or willful misconduct of the Escrow Agent. The indemnification provided by this Section 2.04(c) is in addition to the indemnification provided in Section 4.02 hereof and shall survive the resignation or removal of the Escrow Agent and the termination of this Escrow Agreement.

Section 2.05 Disbursements. The Escrow Agent is hereby directed to hold and distribute the Escrowed Property in the following manner:

(a) If on or prior to the Merger Deadline the Escrow Agent receives an executed Merger Consummation Notice, the Escrow Agent shall release all of the Escrowed Property to or as directed by the Company (the date of such release, the “Escrow Release Date”).

(b) If (i) the Escrow Agent has not received an executed Merger Consummation Notice on or prior to the Merger Deadline, (ii) URNA notifies the Escrow Agent in writing that (a) URNA has determined that the Merger will not be consummated on or before the Merger Deadline or (b) the Merger Agreement has been terminated or (iii) URNA fails to timely deposit (or cause to be timely deposited) any amounts required by Section 2.02 hereof (provided that any deposit of an Additional Amount shall be considered timely if made within four days of the applicable deposit date as provided in Section 2.02(d) hereof), then the Escrow Agent, without the requirement of notice to or action by the Company, the Trustee or any other Person, shall, within one Business Day, liquidate all Escrowed Property and release the Escrowed Property to the Trustee (the date of any such release is referred to herein as the “Escrow Termination Date”).

(c) If an interest payment date on any of the Notes shall have occurred while Escrowed Property is on deposit in the applicable Escrow Account, then the Escrow Agent shall, on each such interest payment date, liquidate an amount of applicable Escrowed Property sufficient to pay the interest then due on the applicable Notes (as calculated in accordance with the terms of the applicable Indenture) and release such cash amount to the Trustee for payment of such interest on the applicable Notes.

(d) The Escrow Agent is authorized to seek confirmation of any instructions by telephone calls back to each of the Company and the Trustee and the Escrow Agent may conclusively rely upon the confirmations, if consistent, by authorized officers of the Company and Trustee. To ensure the accuracy of the instructions it receives, the Escrow Agent may record call backs. If the Escrow Agent is unable to verify the instruction, or is not satisfied, in its sole

discretion, with the verification it receives, it will not execute the instruction until all issues have been resolved to its satisfaction. The persons and telephone numbers for call backs may be changed only in writing, signed by an authorized officer of the Company and the Trustee, actually received and acknowledged by the Escrow Agent. The Company and the Trustee acknowledge that these security procedures for funds transfers are commercially reasonable.

(e) All disbursements of funds from the Escrowed Property shall be subject to the fees and claims of Escrow Agent pursuant to Sections 4.01 and 4.02 hereof.

Section 2.06 Termination.

This Escrow Agreement shall terminate upon the distribution of all Escrowed Property from the Escrow Accounts in accordance with Section 2.05; provided that the provisions of Sections 2.04(c), 4.01 and 4.02 hereof shall survive such termination.

PROVISIONS CONCERNING THE ESCROW AGENT

Section 4.01 Compensation.

For services rendered hereunder, the Escrow Agent shall be entitled to such compensation as shall be agreed to in writing as set forth on Exhibit C hereto between the Company and the Escrow Agent. Company agrees to pay such compensation and to reimburse the Escrow Agent for the reasonable and documented out-of-pocket expenses (including, without limitation, reasonable and documented attorneys’ fees and expenses subject to the Company’s Outside Counsel Guidelines, a copy of which has been provided to such attorneys) incurred by it in connection with the services rendered by it hereunder. In the event that any fees and expenses owed to the Escrow Agent (or its counsel) are not paid to the Escrow Agent within 90 calendar days following the presentment of an invoice for the payment of such fees and expenses or the demand for such payment, then the Escrow Agent may, without further action or notice, pay such fees from the Escrowed Property and may sell, convey or otherwise dispose of any Escrowed Property for such purpose. The Escrow Agent may withhold from any distribution of the Escrowed Property an amount equal to any invoiced and unpaid fees and expenses to which the Escrow Agent is entitled hereunder; provided that at least 90 calendar days have elapsed since presentment of the invoice. The provisions of this Section shall survive the termination of this Escrow Agreement or the resignation or removal of the Escrow Agent.

Section 4.02 Indemnification.

The Company agrees to indemnify the Escrow Agent for, and to hold it harmless against, any and all loss, liability, damage, claim, cost or expense, including reasonable and documented attorneys’ fees and expenses (including the costs and expenses of defending against any claim of liability, regardless of who asserts such claim), incurred by the Escrow Agent arising out of or in connection with its appointment as Escrow Agent hereunder, except such losses, liabilities, damages, claims, costs or expenses as may result from the gross negligence or willful misconduct of the Escrow Agent. The Escrow Agent shall incur no liability and shall be indemnified and held harmless by the Company for, or in respect of, any actions taken, omitted to be taken or suffered to be taken in good faith by the Escrow Agent in reliance upon any signature, endorsement, assignment, certificate, order, request, notice, instruction or other instrument or document believed to be valid and genuine. The Escrow Agent shall notify the Company, by letter or facsimile transmission, of a claim against the Escrow Agent or of any action commenced against the Escrow Agent, promptly after the Escrow Agent shall have received written notice thereof. The Company shall be entitled to participate at its own expense in the defense of any such claim or other action and, if the Company so elects, the Company shall assume the defense of any suit brought to enforce any such claim. In the event that the Company assumes the defense of any such suit, the Company shall not be liable for the fees and expenses of any additional counsel thereafter retained by the Escrow Agent, so long as the Company shall retain counsel reasonably satisfactory to the Escrow Agent; provided, that the Company shall not be entitled to assume the defense of any such action if the named parties to such action include both the Escrow Agent and the Company and representation of both parties

by the same counsel would, in the written opinion of the Escrow Agent’s counsel, be inappropriate due to actual or potential conflicting interests between the Escrow Agent and the Company. The provisions of this Section shall survive the termination of this Escrow Agreement or the resignation or removal of the Escrow Agent.

Section 4.03 Rights of Escrow Agent.

The Escrow Agent:

(a) shall not be liable for any act or omission by it unless such act or omission constitutes gross negligence or willful misconduct; in no event shall the Escrow Agent be liable to the Company or any third party for special, punitive, indirect or consequential damages, including but not limited to lost profits, irrespective of whether the Escrow Agent has been advised of the likelihood of such loss or damage and regardless of the form of action arising in connection with this Escrow Agreement;

(b) shall have no duties or obligations other than those specifically set forth herein or as may be subsequently agreed to in writing between the Escrow Agent, the Company and the Trustee, and the Escrow Agent shall have no liability under, and no duty to inquire as to, the provisions of any agreement other than this Escrow Agreement;

(g) may perform any duties hereunder either directly or by or through agents and attorneys; provided that the Escrow Agent shall not be responsible for the misconduct or negligence on the part of any such agent or attorney appointed by it with due care hereunder.

Section 4.04 Disagreements.

If, at any time, (a) there shall exist any dispute with respect to the holding or disposition of all or any portion of the Escrowed Property or any other obligations of the Escrow Agent hereunder or (b) the Escrow Agent is in doubt as to the action to be taken hereunder, the Escrow Agent is authorized to retain the Escrowed Property until (i) such dispute or uncertainty shall be resolved to the satisfaction of the Escrow Agent in its sole discretion or (ii) the Escrow Agent files an interpleader action in any court of competent jurisdiction, and upon the filing thereof, the Escrow Agent shall be relieved of all liability as to the Escrowed Property and shall be entitled to recover reasonable and documented attorneys’ fees, expenses and other costs incurred in commencing and maintaining any such interpleader action. The Escrow Agent shall be entitled to act on any resultant settlement agreement or court order without further question, inquiry or consent. The Escrow Agent shall have no liability to the Company or any other person with respect to any suspension of performance or disbursement into court, specifically including any liability or claimed liability that may arise, or be alleged to have arisen, out of or as a result of any delay in the disbursement of the Escrowed Property or any delay in, or with respect to, any other action required or requested of Escrow Agent.

Section 4.05 Attachment of Escrowed Property; Compliance with Legal Orders.

In the event that any Escrowed Property shall be attached, garnished or levied upon by any court order, or the delivery thereof shall be stayed or enjoined by an order of a court, or any order, judgment or decree shall be made or entered by any court order affecting the Escrowed Property, the Escrow Agent is hereby expressly authorized, in its sole discretion, to respond as it deems appropriate or to comply with all writs, orders or decrees so entered or issued, or which it is advised, by written opinion of a legal counsel of its own choosing, is binding upon it. In the event that the Escrow Agent obeys or complies with any such writ, order or decree, it shall not be liable to the Company or to any other person, firm or corporation, should, such compliance notwithstanding, such writ, order or decree be subsequently reversed, modified, annulled, set aside or vacated.

Section 4.06 Resignation.

Escrow Agent may resign and be discharged from the performance of its duties hereunder at any time by giving ten days written notice to the Company and the Trustee specifying the date when such resignation shall take effect.

The Escrow Agent shall transmit all records pertaining to the Escrowed Property and shall pay all Escrowed Property to the successor escrow agent, after making copies of record the Escrow Agent deems advisable and after deduction and payment to the Escrow Agent of all fees and expenses (including court costs and reasonable and documented attorneys’ fees and expenses) payable to, incurred by, or expected to be incurred by the Escrow Agent in connection with the performance of its duties and the exercise of its rights hereunder. Upon delivery of the Escrowed Property to the successor escrow agent or to a court of competent

jurisdiction as provided above, the Escrow Agent shall have no further duties, responsibilities or obligations hereunder.
