Separation Agreement dated November 1, 2017 between the Company and James Michener

This letter agreement (the “Agreement”) will confirm our understanding regarding your retirement from Assured Guaranty Ltd. (the “Company”).

In discussions with the Company, you and the Company have agreed that you will resign as General Counsel and as an executive officer of the Company and its Affiliates (as defined in Section 3.5 of this Agreement), effective as of December 31, 2017 (the “Resignation Date”). Subject to the terms of this Agreement, during the period beginning on January 1, 2018 and ending on December 31, 2018 (the “Retirement Date” and the period between January 1, 2018 and the Retirement Date referred to as the “Transition Period”), you shall remain employed by the Company as a non-executive officer with a title of Senior Advisor to the Chief Executive Officer of the Company. The effective date of your separation from all positions and employment with the Company and its Affiliates will be the Retirement Date or, if earlier, the date your termination occurs for any other reason (the date of your termination referred to as the “Separation Date”). As a result of your retirement and in recognition of your years of exceptional service to the Company and in order to incentivize you to remain with the Company through the Retirement Date, the Company has approved certain rights to continued eligibility for future cash and equity grants and to accelerated and continued vesting of unvested equity awards held by you as of the Retirement Date that were granted pursuant to the Assured Guaranty Ltd. 2004 Long-Term Incentive Plan, as amended (the “LTIP”) all as detailed below in Section 2. The offer to you set forth in this Agreement shall remain outstanding during the period described in the release of claims attached hereto as Exhibit A (the “First Release”), provided that the Company may, in its sole discretion, by written notice to you, extend this date. The release of claims attached hereto as Exhibit B (the “Second Release”) should be signed and returned to the Company on or after your Separation Date such that the Second Release becomes effective within the sixty-day period following your Separation Date; provided, however, that the Second Release must be signed by someone with applicable authority to sign on your behalf in the event of your death or Permanent Disability. You shall be considered to be Permanently Disabled if you become entitled to long-term disability benefits pursuant to any applicable long-term disability plan maintained by the Company or an Affiliate or, if no such long-term disability plan is maintained, if you would be treated as “disabled” in accordance with the provisions of Treas. Reg. §1.409A-3(i)(4).

You shall be entitled to compensation, benefits, payments, and distributions from the Company and its Affiliates in accordance with this Section 2.

2.1.    Amounts Prior to Retirement Date.

(a)    Base Salary. Your annual base salary through the Separation Date shall remain at no less than $625,000.

(b)    2017 Cash Incentive Payment. In February 2017, the Compensation Committee of the Company’s Board of Directors (the “Compensation Committee”) assigned an individual target cash incentive amount related to your 2017 performance (the “2017 Cash Incentive Payment”) of 2.00x your annual base salary. Consistent with past practice and subject to your continued employment through the payment date, which will be no later than March 15, 2018, your actual 2017 Cash Incentive Payment will be determined by the Compensation Committee, consistent with other executive officers and based on your actual 2017 performance; provided, however, if you incur a termination of employment due to death or Permanent Disability prior to the payment date, you shall remain eligible to receive the 2017 Cash Incentive Payment based on your actual performance through the date of such termination as determined by the Compensation Committee. If you incur a termination for any reason other than due to death or Permanent Disability prior to the payment date of the 2017 Cash Incentive Payment, you shall forfeit your right to the 2017 Cash Incentive Payment.

(c)    2017 Equity Award. To the extent you are granted an award of long-term incentive compensation (the “2017 Equity Award”) by the Compensation Committee relating to your 2017 performance, such award will be in the form of Restricted Stock Units pursuant to a grant agreement substantially in the form attached hereto as Exhibit C, and will be awarded no later than March 15, 2018; provided, however, in the event that you incur a termination of employment due to death or Permanent Disability prior to the date of grant, you shall be entitled to a cash payment on the date such grant would have otherwise been made in a value equal to what would have been the target nominal value of such Restricted Stock Units. Consistent with past practice and subject to your continued employment through the date of grant, the nominal value of the 2017 Equity Award will be determined by the Compensation Committee, consistent with other executive officers and based on your actual 2017 performance; provided, however, if you incur a termination of employment due to death or Permanent Disability prior to the date of grant, you shall remain eligible to receive the 2017 Equity Award (in cash as noted above) based on your actual performance through the date of such termination as determined by the Compensation Committee. If you incur a termination for any reason other than due to death or Permanent Disability prior to the date of grant of the 2017 Equity Award, you shall forfeit your right to the 2017 Equity Award.

(d)    Executive Severance Plan. For the avoidance of doubt, you shall remain eligible for severance payments pursuant to the Assured Guaranty Ltd. Executive Severance Plan (the “Severance Plan”) in the event you incur a Qualifying Termination (as defined in the Severance Plan) prior to the Retirement Date subject to all applicable terms of the Severance Plan.

(e)    Employee Benefits. Prior to your Separation Date, you shall remain eligible for the employee benefits plans maintained by the Company and its Affiliates subject to the terms of such plans.

(f)    Within thirty days of the Separation Date or such earlier date as required by applicable law, the Company shall pay you (i) the amount of all earned and previously unpaid salary for the period ending on your Separation Date, based upon your then-current annual base salary, and (ii) an amount that is in settlement of any and all vacation days that you have accrued but did not use, and to which you are entitled from the Company. You will not accrue or be entitled to any vacation after your Separation Date.

2.2.    Amounts On or After the Retirement Date. Subject to you remaining employed until the Retirement Date (except as provided below), your signing and not revoking the First and Second Release, and your continued compliance with the terms of Section 3 below, the Company shall pay you the following (collectively referred to herein as the “Separation Payments”); provided, however, that, if the Second Release does not become effective on or before the sixtieth day after your Retirement Date or you violate the terms of Section 3 below, you shall forfeit your right to receive the Separation Payments:

(a)    2018 Cash Incentive Payment. Subject to your continued employment in 2018, in February 2019, the Compensation Committee will grant you a cash incentive award related to your 2018 performance (the “2018 Cash Incentive Payment”) with a target amount of 2.00x your annual base salary. Consistent with past practice and subject to your continued employment through the Retirement Date, your actual 2018 Cash Incentive Payment, which will be paid no later than March 15, 2019, will be determined by the Compensation Committee, consistent with other executive officers and based on your actual 2018 performance; provided, however, if you incur a termination of employment due to death or Permanent Disability during 2018 prior to the Retirement Date, you shall remain eligible to receive the 2018 Cash Incentive Payment based on your actual performance during 2018 through the date of such termination as determined by the Compensation Committee. If you incur a termination for any reason other than due to death or Permanent Disability prior to the Retirement Date, you shall forfeit your right to the 2018 Cash Incentive Payment. In addition, subject to the terms of this paragraph, you shall be entitled to an additional payment on the date that the 2018 Cash Incentive Payment, if any, is made to you in an amount equal to the 2018 Cash Incentive Payment multiplied by twelve percent (12%).

(b)    2018 Equity Award. To the extent you are determined to have earned an award of long-term incentive compensation (the “2018 Equity Award”) by the Compensation Committee relating to your 2018 performance, you shall be entitled to cash payments with a total value equal to what would have been the target nominal value of any Restricted Stock Units that would have otherwise been granted to you, and you will be paid such total cash value in two equal installments with fifty percent (50%) paid on December 1, 2019 and the remaining fifty percent (50%) paid on December 1, 2020. Consistent with past practice and subject to your continued employment through the Retirement Date, the nominal value of the 2018 Equity Award will be determined by the Compensation Committee, consistent with other executive officers and based on your actual 2018 performance; provided, however, if you incur a termination of employment due to death or Permanent Disability during 2018 prior to the Retirement Date, you shall remain eligible to receive the 2018 Equity Award (in cash as noted above) based on your actual performance through the date of such termination as

determined by the Compensation Committee. If you incur a termination for any reason other than due to death or Permanent Disability prior to the Retirement Date, you shall forfeit your right to the 2018 Equity Award.

2.3.    Performance Retention Plan. For the 2014 through 2017 tranche of your 2014 performance retention plan (“PRP”) award granted to you previously pursuant to the LTIP as detailed in the terms of Exhibit D, you shall remain eligible to receive the payment during the Transition Period subject to the applicable terms of the LTIP and any applicable grant agreement with such payment to be made no later than March 15, 2018. All other amounts with respect to any other tranches of previously granted PRP awards have already been paid to you.

2.4.    Restricted Stock Units. For restricted stock unit (“RSU”) awards granted to you pursuant to the LTIP that remain unvested as of the date of this Agreement as detailed in the terms of Exhibit D, you shall remain eligible to receive a distribution of shares and payment of any dividend equivalents for any vesting date prior to your Retirement Date subject to the applicable terms of the LTIP and any applicable grant agreement. Subject to you remaining employed until the Retirement Date, your signing and not revoking the First and Second Release, and your continued compliance with the terms of Section 3 below and the applicable terms of the LTIP and any applicable grant agreement, your termination shall treated as a retirement for purposes of such grants and you shall become vested subject to the terms of the award agreement and receive an accelerated distribution of shares and payment of any dividend equivalents pursuant to the RSU awards granted pursuant to the LTIP as detailed in the terms of Exhibit D (“RSU Distributions”); provided, however, that, if the Second Release does not become effective on or before the sixtieth day after your Retirement Date or you violate the terms of Section 3 below or the applicable terms of the LTIP or any applicable grant agreement, you shall forfeit your right to receive the RSU Distributions; provided, further, however, that if you incur a termination prior to the Retirement Date for any reason, your right to vesting or distribution with respect to such termination shall be determined in accordance with the terms of the applicable grant agreement.

2.5.    Performance Stock Units. For performance stock unit (“PSU”) awards granted previously pursuant to the LTIP that remain unvested as of the date of this Agreement as detailed in the terms of Exhibit D, you shall remain eligible to receive a distribution of shares for any vesting date prior to your Retirement Date subject to the applicable terms of the LTIP and any applicable grant agreement. Subject to you remaining employed until the Retirement Date, your signing and not revoking the First and Second Release, and your continued compliance with the terms of Section 3 below, and the applicable terms of the LTIP and any applicable grant agreement, you shall be treated as if you remained employed after the Retirement Date through the applicable vesting date for purposes of the PSU awards granted to you pursuant to the LTIP as detailed in the terms of Exhibit D with the amounts of the applicable distributions determined by the Compensation Committee based on the achievement of the performance goals as of the last day of the applicable performance period subject to the terms of the award agreement (“PSU Distributions”); provided, however, that, if the Second Release does not become effective on or before the sixtieth day after your Retirement Date or you violate the terms of Section 3 below or the applicable terms of the LTIP or any applicable grant agreement, you shall forfeit your right to receive the PSU Distributions; provided, further, however, that if you incur a termination prior to the Retirement Date for any reason, your right to vesting or distribution with respect to such termination shall be determined in accordance with the terms of the applicable grant agreement.

2.6.    COBRA Coverage. On and after your Separation Date, your entitlement to continue medical coverage under the benefit plans of the Company will be determined in accordance with any retiree medical provisions of the plans and with the provisions of section 4980B of the Internal Revenue Code of 1986, as amended (the “Code”), and section 601 of the Employee Retirement Income Security Act of 1974, as amended (which continuation coverage is sometimes referred to as “COBRA coverage”).

You will be entitled to benefits under the Company’s qualified retirement plan and according to the terms of such plan, and you will be entitled to a distribution of your accrued benefits in the AG US Group Services Inc.

The foregoing covenants by you shall be without limitation as to time and geographic applications. Nothing in this Section 3.4 or this Agreement prohibits you from reporting possible violations of applicable law or regulation to any governmental agency or entity or making other disclosures that are protected under the whistleblower provisions of any applicable law or regulation.

Further, the Parties agree that nothing in this Agreement shall be construed to interfere with the ability of any federal, state or local government agency to investigate any such charge or complaint, or your ability to communicate voluntarily with any such agency. However, by signing this Agreement, you understand that you are waiving your right to receive individual relief based on claims asserted in any such charge or complaint, except where such a waiver is prohibited. You understand that your release of claims as contained in this Agreement does not extend to any rights you may have under any laws governing the filing of claims for COBRA, unemployment, disability insurance and/or workers’ compensation benefits.

The Company or its Affiliates will reimburse you for your reasonable costs incurred, upon proper and timely submission of receipts with respect thereto, in accordance with the Company’s or its Affiliates’ then-current policy, practices or procedures. You agree that, in the event you are subpoenaed by any person or entity (including, but not limited to, any government agency) to provide documents or give testimony (in a deposition, court proceeding or otherwise) or are requested by a governmental or regulatory body to provide an interview, which in any way relates to your employment by the Company or any of its Affiliates, you will give prompt notice of such request to General Counsel, AG US Group Services Inc., 1633 Broadway, New York, NY 10019 ***@***) (or his or her successor or designee) and, unless otherwise required by law, will make no disclosure or production until the Company or its Affiliates have had a reasonable opportunity to contest the right of the requesting person or entity to such disclosure or production.

3.8.    Effect of Covenants. Nothing in this Section 3 shall be construed to adversely affect the rights that the Company would possess in the absence of the provisions of such Section.

As part of this Agreement, and in consideration of the additional payments provided to you in accordance with this Agreement, you are required to execute the First Release, in the form set forth as Exhibit A of this Agreement, and the Second Release, in the form set forth as Exhibit B of this Agreement, which are attached to and form a part of this Agreement. This Agreement (including all Exhibits to this Agreement), and the commitments and obligations of all parties hereunder: (a) shall become final and binding immediately following the expiration of your right to revoke the execution of the Second Release in accordance with paragraph 2(d) of the release; (b) shall not become final and binding until the expiration of such right to revoke; and (c) shall not become final and binding if you revoke such execution.

5.1.    Amendment. This Agreement may be amended or canceled only by mutual agreement of the parties in writing, without the consent of any other person. So long as you live, no person, other than the parties hereto, shall have any rights under or interest in this Agreement or the subject matter hereof. It is the intention of the parties that the payments and benefits to which you could become entitled under this Agreement not be subject to accelerated recognition of income or imposition of additional tax under Code Section 409A, and the Agreement shall be construed in a manner that is consistent with this intent.

5.2.    Waiver of Breach. The waiver by either you or the Company (or its Affiliates) of a breach of any provision of this Agreement shall not operate as or be deemed a waiver of any subsequent breach by either you or the Company. Continuation of benefits hereunder by the Company following a breach by you of any provision of this Agreement shall not preclude the Company from thereafter exercising any right that it may otherwise independently have to terminate said benefits based upon the same violation.

5.3.    Effect of Breach. You acknowledge that the Company would be irreparably injured by your violation of Section 3, and you agree that the Company and its Affiliates, in addition to any other remedies available to them for such breach or threatened breach, shall be entitled to a preliminary injunction, temporary restraining order, or other equivalent relief, restraining you from any actual or threatened breach of Section 3. If a bond is required to be posted in order for the Company to secure an injunction or other equitable remedy, the parties agree that said bond need not be more than a nominal sum. You acknowledge that each of the covenants contained in Section 3 are an essential part of this Agreement and a condition to the Company’s agreement to provide the payments and benefits described in Section 2. If any covenant or term of Sections 3 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 Sections 3 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. You also agree that, if you ever challenge the validity of this Agreement, the First Release or the Second Release or if you breach the terms of this Agreement, the First Release or the Second Release or the terms of any applicable grant agreement pursuant to the LTIP, you will forfeit your right to any unpaid payments pursuant to this Agreement and, if paid prior to such breach, you agree to repay the Separation Payments to the Company together with an amount equal to any gain received as a result of the RSU Distributions and the PSU Distributions.

5.4.    Severability. The invalidity or unenforceability of any provision of this Agreement will not affect the validity or enforceability of any other provision of this Agreement, and this Agreement will be construed as if such invalid or unenforceable provision were omitted (but only to the extent that such provision cannot be appropriately reformed or modified); provided, however, that if one or more provisions of the First and Second Release are invalid or unenforceable, the Company may, in its sole discretion, elect to have the entire Agreement treated as invalid and unenforceable.

5.5.    Other Agreements. Except as otherwise specifically provided in this Agreement, this instrument constitutes the entire agreement between you and the Company and supersedes all prior agreements and understandings, written or oral, including, without limitation, the Employment Agreement and any other agreements that may have been made by and between you and the Company or its predecessors or Affiliates; provided, however, that for the avoidance of doubt, as noted in Section 3 of this Agreement, you agree that you remain bound by all applicable terms of the LTIP and all award agreements for awards previously granted to you pursuant to the LTIP.

5.6.    Governing Law. This Agreement shall be construed in accordance with the laws of the State of New York without regard to the conflict of law provisions of any state.

5.7.    Costs. The parties shall each bear their own costs, attorneys’ fees and other fees incurred in connection with this Agreement and the First and Second Release. 

5.8.    Exhibits, Other Documents. Except as otherwise expressly provided in this Agreement, or except where the context clearly requires otherwise, all references in this Agreement to “the Agreement” or “this Agreement” shall be deemed to include references to each of the Exhibits to this Agreement. To the extent that the terms of this Agreement (including the Exhibits to this Agreement) provide that your rights or obligations set forth in this Agreement (including the Exhibits to this Agreement) are to be determined

under, or are to be subject to, the terms of any other plan or other document, this Agreement (including the Exhibits to this Agreement) shall be deemed to incorporate by reference such plan or other document.

5.9.    Counterparts. This Agreement may be executed in more than one counterpart, but all of which together will constitute one and the same agreement.

If you accept the terms of this Agreement, please indicate your acceptance by signing and returning a copy of this Agreement to the undersigned, along with a signed copy of Exhibit A (First Release) and a signed copy of Exhibit B (Second Release) within the time period specified on or after your Separation Date.
