and the Affiliates if the Executive has performed services for the Company and the Affiliates for less than 36 months).

purposes of this Agreement, the term “Specified Employee” shall be defined in accordance with Treas. Reg. §1.409A-1(i) and such rules as may be established by the Chief Executive Officer of the Company or his or her delegate from time to time.

10. Noncompetition

During the term of the Executive’s employment and for a period of 12 months following the termination of his employment for any reason other than a Termination Without Cause, the Executive shall not, directly or indirectly, whether as an employee, consultant, partner, principal, agent, distributor, representative, stockholder (except as a less than one percent stockholder of a publicly traded company or a less than five percent stockholder of a privately held company) or otherwise, engage, within the United States, Bermuda, or the Cayman Islands, if such activities involve insurance or reinsurance of United States based entities or risks that are competitive with the financial guaranty insurance business then being conducted by the Company and which, during the period covered by the Executive’s employment, were conducted by the Company, by the Company. For as long as the above described restrictions on competition apply, the Executive shall not hire any employee or former employee of the Company or any present or former affiliate company of the Company nor encourage any employee of the Company to leave the employ of

the Company. This section will not be in effect after the Executive’s termination of employment, subject to the following:

(i) The Company may, at its option, by notice to the Executive provided to the Executive not later than 10 days after the termination of employment, agree to continue to pay the Executive’s base salary for the period that ends at the earlier of (A) the one year anniversary of the Executive’s termination or resignation from employment for any reason or (B) the last date on which amounts could be paid and satisfy the short-term deferral exception to treatment of such payments as Deferred Compensation (as provided in Treas. Reg. §1.409A-1(b)(4)), and the restrictions of this Section shall remain in effect during the period as to which those payments are made. The Company’s election to make the payments under this paragraph (i) shall apply to not less than the entire period set forth in the preceding sentence, except with the consent of the Executive.

(ii) If the Company elects to make payments in accordance with paragraph (i) above, and such period ends earlier than one-year anniversary of the date of termination, then the Company may, by notice to the Executive during the first 15 days of the taxable year following the taxable year in which the Executive’s termination of employment occurs, elect to continue to make such payments for the remainder of the period ending on the one-year anniversary of the termination date, and the restrictions of this Section shall remain in effect during the remainder of such one-year period. The Company’s election to make the payments under this paragraph (ii) shall apply to not less than the entire period set forth in the preceding sentence, except with the consent of the Executive.

11. Confidential Information

The Executive covenants that he shall not, without the prior written consent of the Chief Executive Officer use, or disclose to any person (other than an employee of either of the Company, or other person to whom disclosure is necessary to the performance by the Executive of his duties in the employ of the Company) any confidential or proprietary information about the Company or their business, unless and until such information has become known to the public generally (other than as a result of unauthorized disclosure by the Executive). The foregoing covenants by the Executive shall be without limitation as to time and geographic applications.

12. Remedy for Violation of Noncompetition or Confidential Information Provisions

Without intending to limit the remedies available to the Company for the breach of any of the Executive’s covenants in Sections 10 and 11, the Executive acknowledges and agrees that damages at law are an insufficient remedy for the Company and that, accordingly, the Company shall be entitled to apply for and obtain injunctive relief in any court of competent jurisdiction to restrain the breach or threatened breach, or otherwise specifically enforce, any or all of said covenants. The Parties acknowledge that each of the covenants contained in Sections 10 and 11 is an essential element of this Agreement. If any covenant or term of Section 10 or 11 or any portion thereof of this Section 12, is determined to be invalid or unenforceable in any instance, such determination shall not prevent the reassertion thereof with respect of any other breach or violation. If, in any proceeding, a court (or other tribunal) refuses to enforce the covenants contained in Section 11 or 12 or this Section 12 because such covenants cover too extensive a geographic area or too long a period of time, any such covenant shall be deemed amended to the

extent (but only to the extent) required by law to permit its enforceability hereunder.

Notwithstanding anything contained in this Agreement to the contrary, in the event that the Executive’s employment is terminated without Cause (as defined in Section 9(d)(i)) and the Court determines that the Executive has violated Section 10 or 11 of this Agreement, then the Companies shall be entitled to discontinue any payments or benefits that would otherwise be provided under Section 9(d) and the Executive shall forfeit his rights to the same.

13. Withholding

Anything in this Agreement to the contrary notwithstanding, all payments required to be made by the Company hereunder to the Executive shall be subject to withholding of such amounts relating to taxes as the Company may reasonably determine they are required to withhold pursuant to any applicable law or regulation. In lieu of withholding such amounts, in whole or in part, the Company may, in their sole discretion, accept other provision for payment of taxes as required by law, provided they are satisfied that all requirements of law affecting their responsibilities to withholding such taxes have been satisfied.

14. Arbitration of All Disputes

Subject to the provisions of Section 14, any controversy or claim arising out of or relating to this Agreement or the breach thereof shall be settled by arbitration in the City of New York in accordance with American Arbitration Association’s National Rules for Resolution of Employment Disputes.

15. Entire Agreement

This Agreement as in effect as of the Amendment Effective Date contains the entire agreement between the Parties concerning the subject matter hereof and supercedes all prior agreements, undertakings, discussions, negotiations, and undertakings, whether written or oral, between the Company and the Executive with respect thereto, including, but not limited to, the version of this Agreement entered into as of the Original Effective Date and as in effect immediately prior to the Amendment Effective Date.

16. Assignability; Binding Nature

This Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors, heirs, and assigns. No rights or obligations of the Executive under this Agreement may be assigned or transferred by the Executive, other than his rights to receive salary and bonuses hereunder which may be transferred by will or operation of law subject to the limitations of this Agreement. No rights or obligations of the Company under this Agreement may be assigned or transferred by the Company except that such rights or obligations may be assigned or transferred pursuant to a merger or consolidation in which the Company is not the continuing entity, or the sale or liquidation of all or substantially all of the assets of the Company, provided that that assignee or transferee is the successor to all or substantially all of the assets of the Company and such assignee or transferee assumes the liabilities, obligations, and duties of the Company as contained in this Agreement, either contractually or as a matter of law.

Gross-Up Provisions

(a) Anything in this Agreement to the contrary notwithstanding, except for paragraph (b) below, in the event it shall be determined that the Executive shall become entitled to payments and/or benefits provided by this Agreement or any other amounts in the “nature of compensation” (whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement with the Company or any affiliate, any person whose actions result in a change of ownership or effective control of the Company covered by Section 280G of the Code or any person affiliated with the Company or such person) as a result of such change in ownership or effective control of the Company (a “Payment”) would be subject to the excise tax imposed by Section 4999 of the Code or any interest or penalties are incurred by the Executive with respect to such excise tax (such excise tax, together with any such interest and penalties, are hereinafter collectively referred to as the “Excise Tax”), then the Executive shall be entitled to receive an additional payment (a “Gross-Up Payment”) in an amount such that after payment by the Executive of all taxes (including any interest or penalties imposed with respect to such taxes), including, without limitation, any income taxes (and any interest and penalties imposed with respect thereto) and Excise Tax imposed upon the Gross-Up Payment, the Executive retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payments.

(b) Notwithstanding the provisions of paragraph (a) above, if it shall be determined that the Executive would otherwise be entitled to the Gross-Up Payment, but the value of all Payments do not exceed 310% of the Executive’s “base amount,” within the meaning of Section 280G of the Code, then no Gross-Up Payment shall be made to the Executive and the amounts payable under this Agreement or any other amounts in the “nature of compensation” (whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement with the Company) shall be reduced so that the value of all Payments, in the aggregate, equals the Safe Harbor Amount. The “Safe Harbor Amount” means 2.99 times the Executive’s “base amount,” within the meaning of Section 280G of the Code. The reduction in accordance with this paragraph (b) shall be made in the following order:

(i) First, by reducing the cash amounts of Payments (excluding coverage under a hospitalization plan, major medical plan, dental plan, group-term life insurance plan, accidental death and dismemberment plan (“welfare benefits”) that would not constitute Deferred Compensation (with the Payments subject to such reduction to be determined by the Company), to the extent necessary to decrease the Payments to the Base Amount.

(ii) Next, if after the reduction to zero of the amounts described in paragraph (i) above, the remaining scheduled Payments are greater than the Base Amount, then by reducing the cash amounts of Payments (excluding welfare benefits) that constitute Deferred Compensation, with the reductions to be applied first to the Payments scheduled for the latest distribution date, and then applied to distributions scheduled for progressively earlier distribution dates, to the extent necessary to decrease the Payments to the Base Amount.

As a result of uncertainty in the application of Section 280G of the Code at the time of any initial determination by the Accounting Firm (as described in paragraph (c) below), it is possible that Payments will have been paid or distributed by the Company which should not be so paid or

distributed (“Overpayment”) or that additional Payments which were not paid or distributed by the Company could have been so paid or distributed (“Underpayment”), in each case, consistent with the calculation of the amount due hereunder. In the event that the Accounting Firm determines that an Overpayment has been made, any such Overpayment shall be treated for all purposes as a loan to the Executive which the Executive shall repay to the Company promptly upon receiving notice of such Overpayment together with interest at the applicable federal rate provided for in Section 7872(f)(2) of the Code; provided, however, that no amount shall be payable by the Executive to the Company (or if paid by the Executive to the Company shall be returned to the Executive) if and to the extent such payment would not reduce the amount which is nondeductible under Section 280G of the Code or which is subject to taxation under Section 4999 of the Code. In the event that the Accounting Firm determines that an Underpayment has occurred, any such Underpayment shall be promptly paid by the Company to or for the benefit of the Executive together with interest at the applicable federal rate provided for in Section 7872(f)(2) of the Code.

(c) Subject to the provisions of paragraph (d) below, all determinations required to be made under this Exhibit B, including whether and when a Gross-Up Payment is required and the amount of such Gross-Up Payment, or whether a reduction in Payments is required under paragraph (b) above is required, and the assumptions to be utilized in arriving at such determination, shall be made by a nationally recognized accounting firm (the “Accounting Firm”) which shall provide detailed supporting calculations both to the Company and the Executive within 15 business days of the receipt of notice from the Executive that there has been a Payment, or such earlier time as is requested by the Company. The Accounting Firm shall be jointly selected by the Company and the Executive and shall not, during the two years preceding the date of its selection, have acted in any way on behalf of the Company or its affiliated companies. If the Company and the Executive cannot agree on the firm to serve as the Accounting Firm, then the Company and the Executive shall each select a nationally recognized accounting firm and those two firms shall jointly select a nationally recognized accounting firm to serve as the Accounting Firm. All fees and expenses of the Accounting Firm shall be borne solely by the Company. Any Gross-Up Payment, as determined pursuant to this Exhibit B, shall be paid by the Company to the Executive within five days of the receipt of the Accounting Firm’s determination. If the Accounting Firm determines that no Excise Tax is payable by the Executive, it shall furnish the Executive with a written opinion that failure to report the Excise Tax on the Executive’s applicable federal income tax return would not result in the imposition of a negligence or similar penalty. Any determination by the Accounting Firm shall be binding upon the Company and the Executive. As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments which will not have been made by the Company should have been made (a “Gross-Up Underpayment”), consistent with the calculations required to be made hereunder. In the event that the Company exhausts its remedies pursuant to paragraph (d) below and the Executive thereafter is required to make a payment of any Excise Tax, the Accounting Firm shall determine the amount of the Gross-Up Underpayment that has occurred and any such Gross-Up Underpayment shall be promptly paid by the Company to or for the benefit of the Executive.

(d) The Executive shall notify the Company in writing of any claim by the Internal Revenue Service that, if successful, would require the payment by the Company of a Gross-Up Payment. Such notification shall be given as soon as practicable but no later than ten business days after the Executive is informed in writing of such claim and shall apprise the Company of the nature of such

claim and the date on which such claim is requested to be paid. The Executive shall not pay such claim prior to the expiration of the 30-day period following the date on which he or she gives such notice to the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies the Executive in writing prior to the expiration of such period that it desires to contest such claim, the Executive shall:

(i) give the Company any information reasonably requested by the Company relating to such claim,

(ii) take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to time, including, without limitation, accepting legal representation with respect to such claim by an attorney reasonably selected by the Company,

(iii) cooperate with the Company in good faith in order effectively to contest such claim, and

(iv) permit the Company to participate in any proceedings relating to such claim; provided, however, that the Company shall bear and pay directly all costs and expenses (including additional interest and penalties) incurred in connection with such contest and shall indemnify and hold the Executive harmless, on an after-tax basis, for any Excise Tax or income tax (including interest and penalties with respect thereto) imposed as a result of such representation and payment of costs and expenses.

Without limitation on the foregoing provisions of this paragraph (d), the Company shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forego any and all administrative appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct the Executive to pay the tax claimed and xxx for a refund or contest the claim in any permissible manner, and the Executive agrees to prosecute such contest to a determination before any administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Company shall determine; provided, however, that if the Company directs the Executive to pay such claim and xxx for a refund, the Company shall advance the amount of such payment to the Executive, on an interest-free basis and shall indemnify and hold the Executive harmless, on an after-tax basis, from any Excise Tax or income tax (including interest or penalties with respect thereto) imposed with respect to such advance or with respect to any imputed income with respect to such advance; and further provided the Executive shall not be required by the Company to agree to any extension of the statute of limitations relating to the payment of taxes for the taxable year of the Executive with respect to which such contested amount is claimed to be due unless such extension is limited solely to such contested amount. Furthermore, the Company’s control of the contest shall be limited to issues with respect to which a Gross-Up Payment would be payable hereunder and the Executive shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or any other taxing authority.

(e) If, after the receipt by the Executive of an amount advanced by the Company pursuant to paragraph (d) above, the Executive becomes entitled to receive any refund with respect to such claim, the Executive shall (subject to the Company’s complying with the requirements of paragraph (d) above) promptly pay to the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto). If, after the receipt by the Executive of an amount

advanced by the Company pursuant to paragraph (d) above, a determination is made that the Executive shall not be entitled to any refund with respect to such claim and the Company does not notify the Executive in writing of its intent to contest such denial of refund prior to the expiration of 30 days after such determination, then such advance shall be forgiven and shall not be required to be repaid and the amount of such advance shall offset, to the extent thereof, the amount of Gross-Up Payment required to be paid.

(f) If, pursuant to regulations issued under Section 280G or 4999 of the Code, the Company and the Executive were required to make a preliminary determination of the amount of an excess parachute payment and thereafter a redetermination of the Excise Tax is required under the applicable regulations, the parties shall request the Accounting Firm to make such redetermination. If as a result of such redetermination an additional Gross-Up Payment is required, the amount thereof shall be paid by the Company to the Executive within five days of the receipt of the Accounting Firm’s determination. If the redetermination of the Excise Tax results in a reduction of the Excise Tax, the Executive shall take such steps as the Company may reasonably direct in order to obtain a refund of the excess Excise Tax paid. If the Company determines that any suit or proceeding is necessary or advisable in order to obtain such refund, the provisions of paragraph (d) above relating to the contesting of a claim shall apply to the claim for such refund, including, without limitation, the provisions concerning legal representation, cooperation by the Executive, participation by the Company in the proceedings and indemnification by the Company. Upon receipt of any such refund, the Executive shall promptly pay the amount of such refund to the Company. If the amount of the income taxes otherwise payable by the Executive in respect of the year in which the Executive makes such payment to the Company is reduced as a result of such payment, the Executive shall, no later than the filing of his income tax return in respect of such year, pay the amount of such tax benefit to the Company. In the event there is a subsequent redetermination of the Executive’s income taxes resulting in a reduction of such tax benefit, the Company shall, promptly after receipt of notice of such reduction, pay to the Executive the amount of such reduction. If the Company objects to the calculation or recalculation of the tax benefit, as described in the preceding two sentences, the Accounting Firm shall make the final determination of the appropriate amount. The Executive shall not be obligated to pay to the Company the amount of any further tax benefits that may be realized by him or her as a result of paying to the Company the amount of the initial tax benefit.
