On the date that is eleven (11) Business Days after receipt by the Escrow Agent of the Holdco 280G Payment Notice, unless the Escrow Agent has received an objection notice from the Stockholders’ Representative in accordance with the preceding sentence, the Escrow Agent shall pay (x) Holdco from the 280G Escrow Fund the Holdco 280G Payment Amount, and (y) to the extent any amounts remain in the 280G Escrow Account after the making of the Holdco 280G Payment Amount, the Rights Agent from the 280G Escrow Fund the entire amount remaining in the 280G Escrow Account including all interest, dividends or profit on or proceeds or other income earned thereon.

If the Stockholders’ Representative shall object to the calculation of the First CVR Payment Amount or any elements of such First CVR Payment Amount set forth in the First CVR Payment Notice (x) on account of mathematical error, (y) on account of a failure to include any Vowel Tax Refunds or the applicable portion of Vowel Shared Tax Offset Amounts received by Vowel or its Subsidiaries after the Effective Time and on or before the First CVR Payment Event Date, or (z) on the grounds that any Recoupment Amount included in the First CVR Payment Notice either has been paid or no notice for such Recoupment Amount has been delivered under this Section 3, or on any other grounds that would be permissible under Sections 3.1, 3.2, 3.3 or 3.4, as applicable, then the Stockholders’ Representative shall deliver a reasonably detailed written notice of such objection (the “First CVR Objection Notice”) to the Escrow Agent and Holdco within twenty (20) Business Days after the First CVR Payment Notice was received by it in accordance with the terms of this Section 3.6(a) and Section 13 of this Agreement, which notice must set forth a calculation of the additional amount that it reasonably believes should be paid to the Rights Agent (the “First CVR Disputed Amount”); provided, however, if the Stockholders’ Representative shall fail to timely deliver the First CVR Objection Notice in accordance with this sentence (which notice must include such detail as is required by this paragraph), it shall have thereupon irrevocably waived any right to object to such First CVR Payment Notice. If any portion of the First CVR Disputed Amount is determined to be payable as a result of the dispute resolution procedure in Section 3.7 of this Agreement, then such amount shall be paid to the Rights Agent within five (5) Business Days after resolution of the dispute, unless the Stockholders Representative (in its sole and absolute discretion) has previously elected by written notice to the Escrow Agent to defer such payment until the Second CVR Payment Event Date. Notwithstanding anything to contrary set forth in this Section 3.6(a), to the extent that Holdco fails to deliver the First CVR Payment Notice by the 10^th Business Day after the First CVR Payment Event Date, then the Stockholders’ Representative shall have the right at any time after such 10^th Business Day, but not the obligation, to deliver such First CVR Payment Notice, whereupon Holdco shall have the right to deliver the First CVR

Objection Notice within twenty (20) Business Days after the First CVR Payment Notice was received by it in accordance with the terms of this Section 3.6(a) and Section 13 of this Agreement. The First CVR Payment Notice will include the name of the bank to which such payments shall be made, account name at the bank, account number at the bank to which such payments shall be made, ABA routing number of the bank and any further credit instructions for payment to the account. The Escrow Agent will deduct payments first from principal and second on interest on any payments made from the CVR Escrow Fund.

               (b) Second CVR Payment. Within ten (10) Business Days after the Second CVR Payment Event Date, Holdco shall give written notice to the Escrow Agent and the Stockholders’ Representative calculating in reasonable detail the Second CVR Payment Amount (the “Second CVR Payment Notice”, and together with each Agreed Contingency Payment Notice, each Documented Cost Payment Notice, the 280G Payment Notice, the Holdco 280G Payment Notice, the WC Payment Notice, each Expense Notice and the First CVR Payment Notice, the “Payment Notices”, and each a “Payment Notice”). On or prior to the second Business Day after receipt of the Second CVR Payment Notice, the Escrow Agent shall pay the Rights Agent from the CVR Escrow Account the Second CVR Payment Amount shown in the Second CVR Payment Notice, plus all interest, dividends or profit on or proceeds or other income earned thereon. If the Stockholders’ Representative shall object to the calculation of the Second CVR Payment Amount set forth in the Second CVR Payment Notice (x) on account of mathematical error, (y) on account of a failure to include any Vowel Tax Refunds or the applicable portion of Vowel Shared Tax Offset Amounts received by Vowel or its Subsidiaries after the Effective Time and on or before the Second CVR Payment Event Date, or (z) on the grounds that any Recoupment Amount included in the Second CVR Payment Notice either has been paid or no notice for such Recoupment Amount has been delivered under this Section 3, or on any other grounds that would be permissible under Sections 3.1, 3.2, 3.3 or 3.4, as applicable, then the Stockholders’ Representative shall deliver a reasonably detailed written notice of such objection (the “Second CVR Objection Notice”, and together with each AC Objection Notice, each DC Objection Notice, the WC Objection Notice and the First CVR Objection Notice, the “Objection Notices”, and each an “Objection Notice”) to the Escrow Agent and Holdco within twenty (20) Business Days after the Second CVR Payment Notice was received by it in accordance with the terms of this Section 3.6(b) and Section 13 of this Agreement, which notice must set forth a calculation of the additional amount that it reasonably believes should be paid to the Rights Agent (the “Second CVR Disputed Amount”); provided, however, if the Stockholders’ Representative shall fail to timely deliver the Second CVR Objection Notice in accordance with this sentence (which notice must include such detail as is required by this paragraph), it shall have thereupon irrevocably waived any right to object to such Second CVR Payment Notice. If any portion of the Second CVR Disputed Amount is determined to be payable as a result of the dispute resolution procedure in Section 3.7 of this Agreement, then such amount shall be paid to the Rights Agent within five (5) Business Days after resolution of the dispute. Notwithstanding anything to contrary set forth in this Section 3.6(b), to the extent that Holdco fails to deliver the Second CVR Payment Notice by the 10^th Business Day after the Second CVR Payment

Event Date, then the Stockholders’ Representative shall have the right at any time after such 10^th Business Day, but not the obligation, to deliver such Second CVR Payment Notice, whereupon Holdco shall have the right to deliver the Second CVR Objection Notice within twenty (20) Business Days after the Second CVR Payment Notice was received by it in accordance with the terms of this Section 3.6(b) and Section 13 of this Agreement. The Second CVR Payment Notice will include the name of the bank to which such payments shall be made, account name at the bank, account number at the bank to which such payments shall be made, ABA routing number of the bank and any further credit instructions for payment to the account. The Escrow Agent will deduct payments first from principal and second on interest on any payments made from the CVR Escrow Fund.

               (c) Subsequent CVR Payment. If any funds remain in the CVR Escrow Account after the payments, if any, made from the CVR Escrow Fund pursuant to Section 3.6(b), then, to the extent such funds are subject to an Objection Notice, they shall remain in the CVR Escrow Account until such Objection Notice(s) is/are resolved in accordance with Section 3.7 of this Agreement. Upon resolution of the last such Objection Notice(s) in accordance with this Agreement, all such funds then remaining in the CVR Escrow Account shall promptly be paid either to the Rights Agent for further payment pursuant to the CVR Agreement in accordance with such resolution (if any, the “Subsequent CVR Payment Amount”) or to Holdco, as the case may be. Any payment notice given in connection with directing any such further payment will include the name of each bank to which such payments shall be made, account name at such bank, account number at the bank to which such payments shall be made, ABA routing number of such bank and any further credit instructions for payment to such account.

               (d) Treatment of Excess Employee Payment Fund. Holdco and the Stockholders’ Representative hereby acknowledge and agree that the Excess Employee Payment Fund has been included in the calculation of the First CVR Payment Amount and the Second CVR Payment Amount solely for purposes of convenience and shall not be deemed as part of the CVR Escrow Fund. If, at any time or from time to time after the date hereof and prior to the full distribution of the Excess Employee Payment Fund, the Stockholders’ Representative (in its sole and absolute discretion) desires to direct all or any portion of the Excess Employee Payment Fund to the Rights Agent for payment to the holders of the CVRs, Holdco shall promptly execute a joint direction letter to the Escrow Agent with respect to such payment and shall not have any right to object to such payment.

               3.7 Resolutions of Disputes.

               (a) If the Stockholders’ Representative (or Holdco pursuant to Section 3.6, as the case may be) shall have timely delivered an Objection Notice in accordance with the terms of this Agreement, then Holdco and the Stockholders’ Representative shall attempt to resolve the dispute subject to such Objection Notice as promptly as possible. If Holdco and the Stockholders’ Representative resolve such dispute, they shall deliver to the Escrow Agent a joint written notice (a “Settlement

Notice”) to that effect signed by a duly authorized representative of each of Holdco and the Stockholders’ Representative. Such Settlement Notice shall direct the Escrow Agent to pay from the CVR Escrow Fund to Holdco, the CVR Agent or retain the amount in the CVR Escrow Account, if any, agreed to by both Holdco and the Stockholders’ Representative in settlement of such dispute. If Holdco and the Stockholders’ Representative fail to resolve such dispute within thirty (30) calendar days after receipt by Holdco (or the Stockholders’ Representative pursuant to Section 3.6, as the case may be) of the Objection Notice corresponding to such dispute, either party may at any time thereafter commence an arbitration in order to finally resolve such dispute.

               (b) If Holdco or the Stockholders’ Representative commences arbitration pursuant to Section 3.7(a), such dispute shall be resolved by arbitration administered by the American Arbitration Association under its Commercial Arbitration Rules, and judgment on the Award (as defined below) rendered by the arbitrators may be entered in any court having jurisdiction thereof. The number of arbitrators shall be three. The arbitrators must be independent of each party, meaning that neither they nor their current or past firm may have represented any party within the five (5) years preceding their appointment. The arbitrators shall be lawyers or retired judges. Within fifteen (15) days after the commencement of arbitration, each of Holdco and the Stockholders’ Representative shall select one person to act as arbitrator, and the two selected shall select a third arbitrator within fifteen (15) days of their appointment. If the arbitrators selected by Holdco and the Stockholders’ Representative are unable or fail to agree upon the third arbitrator, the third arbitrator shall be selected by the American Arbitration Association.

               (c) The arbitrators shall only have the power to construe this Agreement, the applicable provisions of the Merger Agreement, the applicable provisions of the CVR Agreement and applicable Law, solely for the purpose of determining whether and to whom payments are due in accordance with this Agreement. The place of the arbitration shall be New York, New York. The arbitrators shall: (a) commence the arbitration proceedings within ten (10) calendar days after the three arbitrators have been appointed, and conduct any hearings as they shall reasonably determine, (b) require such oral and written submissions as they reasonably determine; and (c) order a party to produce business records or other documentation reasonably related to the given dispute that are within such party’s possession and control as they reasonably determine. The arbitrators must issue their written opinion within ninety (90) days of the commencement of the arbitration proceeding (the “Award”), which Award shall specifically direct the Escrow Agent as to the payment of the amount in dispute, and contain an assessment of the fees and costs of such arbitration (consisting of the arbitrators’ reasonable fees and expenses, any amounts payable to the American Arbitration Association, and each party’s reasonable documented out-of-pocket attorneys fees and expenses incurred in connection with such arbitration) against the losing party.

               (d) Except as may be required by Law, neither a party nor an arbitrator may disclose the existence, content or results of any arbitration hereunder without the prior written consent of Holdco and the Stockholders’ Representative, except that either party may deliver a copy of the Award to the Escrow Agent. If the Award

assesses fees and expenses against Holdco in accordance with Section 3.7(c), then Holdco shall promptly pay an amount equal to such fees and expenses to the Escrow Agent for deposit into the CVR Escrow Account and such amount shall be added to the amount then payable from the CVR Escrow Fund to the Rights Agent for distribution under the CVR Agreement. If the Award assesses fees and expenses against the Stockholders’ Representative in accordance with Section 3.7(c), then the Escrow Agent shall promptly pay to Holdco from the CVR Escrow Fund, such fees and expenses. Except as provided in the immediately preceding sentence, upon receipt of the Award, the Escrow Agent shall promptly distribute funds from or retain funds in, as the case may be, the CVR Escrow Fund in accordance with the Award, including all interest, dividends or profit on or proceeds or other income earned thereon, less any fees and expenses paid pursuant to the immediately preceding sentence.

               3.8 Certain Tax Matters.

               (a) The parties hereto hereby acknowledge and agree that, for tax reporting with respect to federal, state and local taxes based on income, Holdco will be treated as the owner of each Escrow Fund and will report all income, gain, loss, credit or deduction, if any, that is earned on, or derived from or attributable to, any investment made from each such Escrow Fund as its income, gain, loss, credit or deduction, in the taxable year or years in which such income tax item is properly includible and pay any taxes attributable thereto, and as of the end of each calendar year and, to the extent required by the U.S. Internal Revenue Service (the “IRS”), such income shall be reported as having been earned by Holdco whether or not such income was disbursed during such calendar year. Holdco will provide the Escrow Agent with an IRS Form W-9 concurrently with its execution and delivery of this Agreement to comply with the Escrow Agent’s legal compliance obligations. The parties hereto understand that if such tax reporting documentation is not provided and certified to the Escrow Agent, the Escrow Agent may be required by the Code and the rules and regulations of the IRS promulgated thereunder, to withhold a portion of any interest or other income earned on the investment of the Escrow Funds.

               (b) Holdco shall be responsible for paying taxes (including any penalties and interest thereon) on all interest and other income earned on any Escrow Fund pursuant to this Agreement and for filing all necessary tax returns with respect to such income. None of Vowel, the Stockholders’ Representative, the holders of the CVRs (collectively, the “Holders”) or the Escrow Agent shall have any obligation to file or prepare any tax returns or prepare any other reports for any taxing authorities concerning matters covered by this Agreement with respect to income earned on any Escrow Fund. The Escrow Agent shall have no responsibility to provide tax forms relating to taxable transactions for claimants or closing payees.

               (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 any portion of the funds in an Escrow Fund, the Escrow Agent shall satisfy such liability to the extent possible from such Escrow Fund. The parties hereto hereby agree, severally and not jointly, to 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 Escrow Funds 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 3.8(c) is in addition to the indemnification provided in Section 5.3 and shall survive the resignation or removal of the Escrow Agent and the termination of this Agreement.

               (d) The Escrow Agent shall not be considered the payor with respect to payments made on Holdco’s, the Stockholders’ Representative’s, the Holders’ or Surratt’s behalf and pursuant to any Payment Notices, notice of an Award or similar disbursement or payment instructions. The Escrow Agent shall not be considered the payor with respect to payments made on Holdco’s, the Stockholders’ Representative’s, the Holders’ or Surratt’s behalf to non-resident aliens and, accordingly, is not the “withholding agent” for purposes of the payments as that term is defined under the rules and regulations of the IRS. The Escrow Agent has no direct knowledge of the recipients of the payments and is not in a position to characterize the nature of the payments made to recipients for tax purposes.

          4. Termination of Agreement. This Agreement shall become effective on the date hereof and its term (the “Term”) shall continue until and terminate upon the full distribution of all Escrow Funds pursuant to Section 3 hereof.

          5. Escrow Agent; Fees; Miscellaneous Matters Concerning Escrow Agent.

               5.1 The Escrow Agent shall be entitled to an administration fee of $2,500 and reimbursement of its reasonable customary and documented out-of-pocket expenses including, but not by way of limitation, the reasonable fees and costs of attorneys or agents which it may find necessary to engage in the performance of its duties hereunder, all to be paid one half by Holdco and one half from CVR Escrow Fund, and the Escrow Agent shall have, and is hereby granted, a prior lien upon any property, cash, or assets of the Escrow Funds, as the case may be, with respect to its unpaid fees and nonreimbursed expenses, superior to the interests of any other persons or entities. Except as expressly provided in the immediately preceding sentence, the Escrow Agent does not have any interest in the Escrow Funds deposited hereunder but is serving as escrow holder only and having only possession thereof.

               5.2 The Escrow Agent agrees to hold and safeguard the Escrow Funds and to perform its duties in accordance with the terms and provisions of this Agreement. Holdco, the Stockholders’ Representative and Surratt agree that the Escrow Agent does not assume any responsibility for the failure of Holdco, the Stockholders’ Representative or Surratt to perform any of their respective obligations in accordance with this Agreement, the Merger Agreement or any other agreement. The acceptance by the Escrow Agent of its responsibilities hereunder is subject to the following terms and conditions, which the parties hereto agree shall govern and control with respect to the Escrow Agent’s rights, duties, liabilities and immunities:

               (a) The Escrow Agent shall be protected in acting upon any written notice, consent, receipt or other paper or document furnished to it, not only as to its due execution and validity and effectiveness of its provisions but also as to the truth and accuracy of any information therein contained, which the Escrow Agent believes to be genuine and what it purports to be. Should it be necessary for the Escrow Agent to act upon any instructions, directions, documents or instruments issued or signed by or on behalf of any corporation, fiduciary, or individual acting on behalf of another party hereto, which the Escrow Agent in believes to be genuine, it shall not be necessary for the Escrow Agent to inquire into such corporation’s, fiduciary’s or individual’s authority. The Escrow Agent is also relieved from the necessity of satisfying itself as to the authority of the persons executing this Agreement in a representative capacity.

               (b) The Escrow Agent shall not be liable for any error of judgment or for any act done or step taken or omitted, or for any mistake of fact or law, or for anything which it may do or refrain from doing in connection herewith, except for its own gross negligence, recklessness or willful misconduct.

               (c) The Escrow Agent may consult with, and obtain advice from, legal counsel in the event of any question as to any of the provisions hereof or the duties hereunder, and it shall incur no liability and shall be deemed to be acting in accordance with the opinion and instructions of such counsel. The reasonable costs of such counsel’s services shall be paid to the Escrow Agent in accordance with Section 5.1 above and clause (f) of this Section 5.2. The Escrow Agent may perform any and all of its duties through its agents, representatives, attorneys, custodians, and/or nominees.

               (d) The Escrow Agent shall have no duties except those which are expressly set forth herein, and it shall not be bound by the Merger Agreement, the CVR Agreement or any agreement of the other parties hereto (whether or not it has any knowledge thereof) or by any notice of a claim, or demand with respect thereto, or any waiver, modification, amendment, termination or rescission of this Agreement, until received and acknowledged by an officer in its Shareowner Services department in writing. The Escrow Agent shall have only those duties as are expressly provided herein, which shall be deemed purely ministerial in nature, and shall under no circumstance be deemed a fiduciary for any of the parties to this Agreement. The Escrow Agent shall neither be responsible for, nor chargeable with, knowledge of the terms and conditions of any other agreement, instrument or document between the other parties hereto, in connection herewith, including without limitation the Merger Agreement or the CVR Agreement. This Agreement sets forth all matters pertinent to the escrow contemplated hereunder, and no additional obligations of the Escrow Agent shall be inferred from the terms of this Agreement or any other agreement. IN NO EVENT SHALL THE ESCROW AGENT BE LIABLE, DIRECTLY OR INDIRECTLY, FOR ANY (i) DAMAGES OR EXPENSES ARISING OUT OF THE SERVICES PROVIDED HEREUNDER, OTHER THAN DAMAGES WHICH RESULT FROM THE ESCROW AGENT’S FAILURE TO ACT IN ACCORDANCE WITH THE STANDARDS SET FORTH IN THIS AGREEMENT, OR (ii) SPECIAL, INDIRECT OR

CONSEQUENTIAL LOSSES OR DAMAGES, EVEN IF THE ESCROW AGENT HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSSES OR DAMAGES.

               (e) In the event that any Escrow Account 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 property deposited under this Agreement, or any part thereof, the Escrow Agent is hereby expressly authorized, in its sole discretion, to obey and comply with all writs, orders or decrees so entered or issued, which it is advised by legal counsel of its own choosing is binding upon it, and in the event that the Escrow Agent obeys or complies with any such writ, order, judgment or decree it shall not be liable to any of the parties hereto or to any other Person by reason of such compliance notwithstanding such writ, order, judgment or decree be subsequently reversed, modified, annulled, set aside or vacated.

               (f) If the Escrow Agent becomes involved in litigation on account of this Agreement, it shall have the right to retain counsel and shall be entitled to reimbursement for all reasonable documented costs and expenses related thereto as provided in Sections 6.1 and 6.3(c) hereof; provided, however, that the Escrow Agent shall not be entitled to any such reimbursement to the extent such litigation ultimately determines that the Escrow Agent acted with gross negligence or willful misconduct.

               (g) In the event that conflicting demands are made upon the Escrow Agent for any situation not addressed or addressed in this Agreement, the Escrow Agent may withhold performance of the terms of this Agreement until such time as said conflicting demands shall have been withdrawn or the rights of the respective parties shall have been settled by court adjudication, arbitration, joint order or otherwise.

               (h) Any corporation or association into which the Escrow Agent may be converted or merged, or with which it may be consolidated, or to which it may sell or transfer its corporate trust business and assets as a whole or substantially as a whole, or any corporation or association resulting from any such conversion, sale, merger, consolidation or transfer to which it is a party, so long as such successor has capital and surplus of at least $5,000,000,000, shall be and become the successor Escrow Agent hereunder and vested with all of the title to the whole property or trust estate and all of the trusts, powers, immunities, privileges, protections and all other matters as was its predecessor, without the execution or filing of any instrument or any further act, deed or conveyance on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

               (i) The Escrow Agent shall not be liable for any action taken or not taken by it in accordance with the direction or consent of the parties or their respective agents, representatives, successors, or assigns. The Escrow Agent shall not be liable for acting or refraining from acting upon any notice, request, consent, direction, requisition, certificate, order, affidavit, letter, or other paper or document believed by it to be genuine and correct and to have been signed or sent by the proper person or persons, without further inquiry into the person’s or persons’ authority. Concurrently with the

execution of this Agreement, the parties hereto shall deliver to the Escrow Agent authorized signers’ forms in the form of Exhibits B-1, B-2 and B-3 to this Agreement.

               (j) The permissive rights of the Escrow Agent to do things enumerated in this Agreement shall not be construed as duties.

               (k) No provision of this Agreement shall require the Escrow Agent to risk or advance its own funds or otherwise incur any financial liability or potential financial liability in the performance of its duties or the exercise of its rights under this Agreement.

               (l) This Agreement is subject to the parties of this Agreement passing all necessary background, compliance and other required or best practice internal and/or mandated compliance measures. The Escrow Agent reserves the right to terminate this Agreement if findings in a compliance related background check or other source determine a reasonable cause eliminating opportunity to continue relation and Escrow Agreement.

               5.3 Holdco, Vowel, the Stockholders’ Representative (solely to the extent of the CVR Escrow Fund and the Excess Employee Payment Fund) and Surratt (solely to the extent of the 280G Escrow Fund) hereby agree, severally and not jointly, to indemnify the Escrow Agent for and to hold it harmless against any loss, liability or expense incurred without gross negligence, recklessness, willful misconduct on the part of the Escrow Agent arising out of or in connection with its performance under this Agreement. The obligations of Holdco, the Stockholders’ Representative and Surratt set forth in this Section 5.3 shall survive the termination or assignment of this Agreement and the resignation or removal of the Escrow Agent.

               5.4 Any tax returns required to be prepared and filed will be prepared and filed by the party which is reported to have received such income with the IRS in all years income is earned, whether or not income is received or distributed in any particular tax year (which party, in accordance with Section 3.8, shall be Holdco), and the Escrow Agent shall have no responsibility for the preparation and/or filing of any tax return with respect to any income earned by the Escrow Funds. Any taxes payable on income earned from the investment of the Escrow Funds shall be paid by the party which is reported to have received such income, whether or not the income was distributed by the Escrow Agent during any particular year (which party, in accordance with Section 3.8, shall be Holdco). The Escrow Agent shall have no obligation to pay any taxes or estimated taxes. After the Escrow Funds and the income earned thereon have been distributed by the Escrow Agent, Holdco, the Stockholders’ Representative and Surratt agree to cooperate and to file any amended reports which may be necessary in order to correct any filings with the IRS which reported income as having been earned by a party which did not actually receive such income.

               5.5 Notwithstanding any provision herein to the contrary, the parties agree that the Escrow Agent may interplead, should any controversy arise involving the parties hereto or any of them or any other Person with respect to this

Agreement or the Escrow Funds, or should a substitute escrow agent fail to be designated as provided herein, or if the Escrow Agent should be in doubt as to what action to take, the Escrow Agent shall have the right, but not the obligation, either to (a) withhold delivery of the applicable Escrow Funds until the controversy is resolved, the conflicting demands are withdrawn or its doubt is resolved or (b) institute a petition for interpleader in any court of competent jurisdiction to determine the rights of the parties hereto. In the event the Escrow Agent is a party to any dispute, the Escrow Agent shall have the additional right to refer such controversy to binding arbitration. Should a petition for interpleader be instituted, or should the Escrow Agent be threatened with litigation or become involved in litigation or binding arbitration in any manner whatsoever in connection with this Agreement or any of the Escrow Funds, Holdco, Vowel and the Stockholders’ Representative (solely to the extent of the CVR Escrow Funds and the Excess Employee Payment Fund) each hereby agree to reimburse the Escrow Agent for one-half (¹/2) of its reasonable attorneys’ fees and any and all other expenses, losses, costs and damages incurred by the Escrow Agent in connection with or resulting from such threatened or actual litigation or arbitration prior to any disbursement hereunder any adverse claim or demand in the courts of the State of New York and the United States District Court located in New York County, New York and the parties agree to the jurisdiction of said Courts over their persons as well as the Escrow Funds.

               5.6 The Escrow Agent agrees that Holdco, Vowel, the Stockholders’ Representative and, to the extent the 280G Escrow Fund has been established and funds remain in the 280G Escrow Account to which Surratt is entitled, Surratt, may, by mutual written agreement executed by all of them (including Surratt in the case of the 280G Escrow Account) at any time, remove the Escrow Agent as escrow agent hereunder, and substitute another bank or trust company therefor, in which event, upon receipt of written notice thereof, payment of any accrued but unpaid fees due the Escrow Agent, and reimbursement of the Escrow Agent’s other fees and expenses, in accordance herewith, the Escrow Agent shall account for and deliver to such substituted escrow agent the entire Escrow Funds, and the Escrow Agent shall thereafter be discharged from all duties hereunder, except for its gross negligence or willful misconduct.

          6. Entire Agreement. This Agreement, the Merger Agreement and the CVR Agreement constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and undertakings, whether written or oral, with respect to the subject matter hereof. Except for the Released Parties pursuant to Section 3.3 of this Agreement, there are no express, implied or intended third party beneficiaries of this Agreement. For the avoidance of doubt, none of the Holders or the Rights Agent shall be a beneficiary of this Agreement.

          7. Amendment; Waiver. This Agreement may not be amended or modified except by an instrument in writing signed by the Stockholders’ Representative, Holdco and the Escrow Agent. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof.

          8. Governing Law. This Agreement shall be governed by the laws of the State of New York without regard for choice of law or conflicts of law principles thereof. Each party hereby (a) irrevocably and unconditionally submits to the exclusive jurisdiction of the courts of the State of New York and of the United States of America, in each case located in the State of New York with respect to all actions and proceedings arising out of or relating to this Agreement or the transaction contemplated hereby, (b) agrees that all claims with respect to any such action or proceeding shall be heard and determined in such New York State or federal court and agrees not to commence an action or proceeding relating to this Agreement or the transactions contemplated hereby except in such courts, (c) irrevocably and unconditionally waives any objection to the laying of venue of any action or proceeding arising out of this Agreement or the transactions contemplated hereby and irrevocably and unconditionally waives the defense of an inconvenient forum, (d) consents to service of process upon it by mailing or delivering such service to the address set forth in Section 13 hereof, and (e) agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

          9. Assignment. Subject to the provisions of Section 5.2(h), this Agreement shall not be assigned without the express written consent of the Stockholders’ Representative and Holdco (which consent may be granted or withheld in the sole discretion of the Stockholders’ Representative and Holdco); provided that Holdco shall be entitled to assign this Agreement to the same extent it is entitled to assign the Merger Agreement and the Stockholders Representative shall be entitled to assign this Agreement to any successor in accordance with Article VIII of the Merger Agreement. Notwithstanding the foregoing, no assignment of the interest of any of the parties hereto shall be binding upon the Escrow Agent unless and until reasonable written evidence of such assignment shall be delivered to the Escrow Agent.

          10. Counterparts. This Agreement may be executed in one or more counterparts, and by the parties hereto in separate counterparts, each of which, when executed, shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement. The exchange of copies of this Agreement and of signature pages by facsimile transmission or by electronic transmission of portable document format (PDF) files or tagged image file format (TIF) files shall constitute effective execution and delivery of this Agreement and may be used in lieu of the originally executed Agreement for all purposes. Signatures of the parties transmitted by facsimile or by electronic transmission of portable document format (PDF) files or tagged image file format (TIF) files shall be deemed to be their original signatures for all purposes.

          12. Severability. To the extent any provision of this Agreement is prohibited by or invalid under the applicable law of any jurisdiction, such provision shall

be ineffective only to the extent of such prohibition or invalidity and only in such jurisdiction, without prohibiting or invalidating such provision in any other jurisdiction or the remaining provisions of this Agreement in any jurisdiction.
