Other words and phrases used in this Agreement are defined pursuant to Section 23, elsewhere in this Agreement or the Plan.

2. Performance-Based Restricted Stock Unit Award. This Agreement specifies the terms of the Performance-Based Restricted Stock Unit Award granted to the Participant. Each Covered Unit represents the right to receive up to two and one-half shares of Stock on the Delivery Date, subject to the terms of this Agreement and the Plan.

3. Performance Percentage. As of the Performance Determination Date, the Performance Percentage shall be determined in accordance with the table below based on the Company’s Relative Total Shareholder Return during the Performance Period. If the Relative Total Shareholder Return in the Performance Period is between percentiles listed on the table below, the Performance Percentage shall be determined using straight line interpolation between the percentiles listed on the table below. For example, if the Relative Total Shareholder Return determined for the Performance Period is the 40th Percentile, the Performance Percentage shall be 75%.

Notwithstanding the foregoing, if, during the Performance Period, the Company’s Total Shareholder Return is a negative number, in no event shall the Performance Percentage be greater than 100%.

Notwithstanding anything herein to the contrary, the Performance Percentage shall be determined by the Committee and certified by the Committee in writing before any shares of Stock are delivered on or after the Delivery Date (or, if earlier, a 457A Delivery Date as defined in Exhibit A); provided, however, that such determination and delivery of shares of Stock shall be made within the period commencing on the Delivery Date (or, if earlier, a 457A Delivery Date) and ending on the later to occur of: (i) the end of the calendar year in which the such date occurs and (ii) the fifteenth day of the third month following such date.

4. Restricted Period. Subject to Section 5 below, with respect to all Covered Units, the “Restricted Period” for the Covered Units shall begin on the Grant Date and end on the earlier to occur of (i) the third anniversary of the Grant Date; or (ii) a Vesting Change in Control. The Committee, in its sole discretion, may accelerate the end of the Restricted Period.

5. Termination of Employment. Except as otherwise provided in this Section 5, if the Participant’s Date of Termination occurs for any reason prior to the last day of the Restricted Period, all Covered Units shall be immediately forfeited.

(a)Death or Disability. If the Participant’s Date of Termination occurs due to the Participant’s death or Disability prior to the last day of the Restricted Period, the Restricted Period shall immediately lapse upon such Date of Termination.

(b)Retirement. If the Participant’s Date of Termination occurs due to a Retirement prior to the last day of the Restricted Period, then, only for purposes of this Section 5, the Participant shall be treated as if his Date of Termination had not occurred prior to the last

day of the Restricted Period, subject to the Participant not engaging in any Competitive Activity or any Post-Retirement Activity prior to the last day of the Restricted Period and subject to the Participant signing and not revoking a general release and waiver of all claims against the Company as required by Section 7.1 of the Severance Plan. If such release is not effective within the 60-day period required by Section 7.1 of the Severance Plan or in the event that the Participant engages in a Competitive Activity or a Post-Retirement Activity prior to the last day of the Restricted Period, the Participant shall immediately forfeit all of the Covered Units.

(c)Qualifying Termination Before a Change in Control. If the Participant’s Date of Termination occurs due to a Qualifying Termination prior to the last day of the Restricted Period and prior to the date of a Change in Control, then, only for purposes of this Section 5 (and not for purposes of determining the Pro-Rata Fraction), the Participant shall be treated as if his Date of Termination had not occurred prior to the last day of the Restricted Period, subject to the Participant not engaging in any Competitive Activity prior to the last day of the Restricted Period and subject to the Participant signing and not revoking a general release and waiver of all claims against the Company as required by Section 7.1 of the Severance Plan. If such release is not effective within the 60-day period required by Section 7.1 of the Severance Plan or in the event that the Participant engages in a Competitive Activity prior to the last day of the Restricted Period, the Participant shall immediately forfeit all of the Covered Units.

(d)Qualifying Termination On or After a Change in Control. If the Participant’s Date of Termination occurs due to a Qualifying Termination prior to the last day of the Restricted Period but on or after the date of a Change in Control that is not a Vesting Change in Control, then, only for purposes of this Section 5 (and not for purposes of determining the Pro-Rata Fraction), the Participant shall be treated as if his Date of Termination had not occurred prior to the last day of the Restricted Period subject to the Participant signing and not revoking a general release and waiver of all claims against the Company as required by Section 7.1 of the Severance Plan. If such release is not effective within the 60-day period required by Section 7.1 of the Severance Plan, the Participant shall immediately forfeit all of the Covered Units.

6. Delivery Date. On the Delivery Date, the Participant shall receive a number of shares of Stock in settlement of his or her Performance-Based Restricted Stock Unit Award. The number of shares of Stock that a Participant shall receive on the Delivery Date shall be determined by multiplying (i) the number of Covered Units (which have not previously been forfeited or cancelled) by (ii) the Performance Percentage determined pursuant to Section 3 above (with such percentage converted to a number by dividing such percentage by 100); provided, however, that (A) if the Participant’s Date of Termination occurred prior to the Delivery Date and prior to a Change in Control due to (x) death, (y) Disability or (z) a Qualifying Termination, then the product of clauses (i) and (ii) shall additionally be multiplied by the Pro-Rata Fraction or (B) if the Participant’s Date of Termination occurred prior to the Delivery Date due to Retirement, then the product of clauses (i) and (ii) shall additionally be multiplied by the Retirement Percentage (with such percentage converted to a number by dividing such percentage

by 100). Shares of Stock received by a Participant pursuant to this Section 6 shall be free of restrictions otherwise imposed by this Agreement and the Plan; provided, however, that the shares of Stock shall remain subject to the terms of this Agreement expressly applicable after such Delivery Date (including, without limitation, Section 13). As of the Delivery Date and settlement of the Performance-Based Restricted Stock Unit Award pursuant to this Section 6, all Covered Units (which have not previously been forfeited or cancelled) shall be cancelled.

7. Change in Control. In the event of a Change in Control, the Company, or the entity that is the surviving entity or successor to the Company following such transaction, may elect to (a) to continue this Performance-Based Restricted Stock Unit Award subject to the terms of this Agreement and the Plan and subject to such adjustments, if any, by the Committee as permitted by Section 5.2(f) of the Plan; or (b), if the Change in Control also satisfies the definition of “change in control event” as set forth in Treas. Reg. 1.409A-3(i)(5), to terminate this Performance-Based Restricted Stock Unit Award and distribute shares of Stock consistent with Treas. Reg. 1.409A-3(j)(4)(ix)(B). In the event that the Company or its successor chooses to terminate this award and make a distribution of shares of Stock as provided in clause (b) of the previous sentence (in which case the Change in Control is a Vesting Change in Control), the payment amount attributable to dividends as described in and determined pursuant to Section 11 shall be determined as if the date of the Vesting Change in Control were the Delivery Date and the number of shares of Stock to be delivered pursuant to Section 6 shall be calculated as if the date of such Vesting Change in Control were the Delivery Date and the shares of Stock received by a Participant pursuant to this Section 7 shall be free of restrictions otherwise imposed by this Agreement and the Plan; provided, however, that the shares of Stock shall remain subject to the terms of this Agreement expressly applicable after the Delivery Date (including, without limitation, Section 13).

8. Section 457A of the Code. If the Covered Units would otherwise constitute nonqualified deferred compensation subject to Code section 457A and the date on which the Covered Units are no longer treated as subject to a substantial risk of forfeiture for purposes of Code section 457A occurs prior to the Delivery Date or a Vesting Change in Control, the terms of Exhibit A shall apply.

9. Withholding. All deliveries and distributions of shares of Stock or vesting of Restricted Shares (granted pursuant to Exhibit A) under this Agreement are subject to withholding of all applicable taxes. At the election of the Participant, and subject to such rules and limitations as may be established by the Committee from time to time, such withholding obligations may be satisfied through the surrender of shares of Stock which the Participant already owns, or to which the Participant is otherwise entitled under the Plan; provided, however, that such shares of Stock may be used to satisfy not more than the maximum individual tax rate for the Participant in applicable jurisdiction for such Participant (based on the applicable rates of the relevant tax authorities (for example, federal, state, and local), including the Participant’s share of payroll or similar taxes, as provided in tax law, regulations, or the authority’s administrative practices, not to exceed the highest statutory rate in that jurisdiction, even if that rate exceeds the highest rate that may be applicable to the specific Participant).

10. Transferability. Except as otherwise provided by the Committee, the Performance-Based Restricted Stock Unit Award (and Covered Units or Restricted Shares subject to this award) may not be sold, assigned, transferred, pledged, or otherwise encumbered.

11. Dividends. To the extent that the Covered Units have not otherwise been forfeited or cancelled prior to the Delivery Date, the Participant will be paid a cash payment on the Delivery Date equal to the number of shares of Stock delivered pursuant to Section 6 multiplied by the total amount of dividend payments made in relation to one share of Stock with respect to record dates occurring during the period between the Grant Date and the Delivery Date.

12. Voting. The Participant shall not be a shareholder of record with respect to the Covered Units and shall have no voting rights with respect to the Covered Units during the Restricted Period or prior to the delivery of shares of Stock pursuant to Section 6 or 7. The Participant shall be a shareholder of record with respect to Restricted Shares granted to the Participant pursuant to Exhibit A.

13. Cancellation and Rescission of Restricted Stock Unit Award.

(a)The Committee may cancel, rescind, suspend, withhold, or otherwise limit or restrict the Performance-Based Restricted Stock Unit Award at any time if the Participant engages in any Competitive Activity or if the Participant engages in any conduct that constitutes Cause or, in the case of a Participant whose Date of Termination has occurred due to Retirement, if the Participant engages in any Post-Retirement Activity.

(b)Immediately prior to the Delivery Date (or, if earlier, a 457A Delivery Date) and prior to the transfer of the shares of Stock to the Participant, the Participant shall certify, to the extent required by the Committee, in a manner acceptable to the Committee, that the Participant is not engaging and has not engaged in any Competitive Activity and, in the case of a Participant whose Date of Termination has occurred due to Retirement, that the Participant is not engaging and has not engaged in any Post-Retirement Activity. In the event a Participant has engaged in any Competitive Activity or, if applicable, any Post-Retirement Activity, prior to or during the twelve months after the later to occur of the Delivery Date or the last day of the Restricted Period with respect to any Covered Units (the “Restrictive Covenant Period”), the right to delivery of shares of Stock with respect to such Covered Units (including the delivery or vesting of any Restricted Shares) may be rescinded by the Committee within two years of the end of the Restricted Covenant Period. In the event of any such rescission, the Participant shall pay to the Company the amount of any gain realized as a result of the prior delivery of shares of Stock applicable to the rescinded Covered Units, in such manner and on such terms and conditions as may be required by the Company, and the Company shall be entitled to set-off against the amount of any such gain any amount owed to the Participant by the Company and/or Subsidiary.

14. Recoupment and Plan Provisions Govern.

(a)Notwithstanding anything in this Agreement to the contrary, the Participant’s rights with respect to the Performance-Based Restricted Stock Unit Award shall be subject to the Assured Guaranty Ltd. Executive Officer Recoupment Policy as amended and restated on November 3, 2015, and as further amended from time to time.

(b)Notwithstanding anything in this Agreement to the contrary, but subject to subparagraph (a) of this Section 14 above, this Agreement shall be subject to the terms of the Plan, a copy of which may be obtained by the Participant from the office of the Secretary of the Company; and this Agreement is subject to all interpretations, amendments, rules and regulations promulgated by the Committee from time to time pursuant to the Plan.

15. Heirs and Successors. Subject to Section 7, this Agreement shall be binding upon, and inure to the benefit of, the Company and its successors and assigns, and upon any person acquiring, whether by merger, consolidation, purchase of assets, or otherwise, all or substantially all of the Company’s assets and business. If any benefits deliverable to the Participant under this Agreement have not been delivered at the time of the Participant’s death, such benefits shall be delivered to the Designated Beneficiary, in accordance with the provisions of this Agreement and the Plan. The “Designated Beneficiary” shall be the beneficiary or beneficiaries designated by the Participant in a writing filed with the Committee in such form and at such time as the Committee shall require. If a deceased Participant fails to designate a beneficiary, or if the Designated Beneficiary does not survive the Participant, any rights that would have been exercisable by the Participant and any benefits distributable to the Participant shall be distributed to the legal representative of the estate of the Participant. If a deceased Participant designates a beneficiary and the Designated Beneficiary survives the Participant but dies before the complete distribution of benefits to the Designated Beneficiary under this Agreement, then any benefits distributable to the Designated Beneficiary shall be distributed to the legal representative of the estate of the Designated Beneficiary.

16. Administration. The authority to manage and control the operation and administration of this Agreement shall be vested in the Committee, and the Committee shall have all powers with respect to this Agreement as it has with respect to the Plan. Any interpretation of this Agreement by the Committee and any decision made by it with respect to this Agreement is final and binding on all persons. The Committee shall have the authority to obtain such information from the Participant (including tax return information) as it determines may be necessary to confirm that the Participant is in compliance with the requirements applicable to Competitive Activity, and if the Participant fails to provide such information, the Committee may, in its discretion, conclude that the Participant is not in compliance with such requirements.

18. Not an Employment Contract. The Performance-Based Restricted Stock Unit Award will not confer on the Participant any right with respect to continuance of employment or other service with the Company or any Subsidiary, nor will it interfere in any way with any right the Company or any Subsidiary would otherwise have to terminate or modify the terms of such Participant’s employment or other service at any time.

_________________________

Assured Guaranty Ltd.

I hereby agree to all the terms, restrictions and conditions set forth in the Agreement:

    If the Covered Units constitute nonqualified deferred compensation subject to Code section 457A and the date on which the Covered Units are no longer treated as subject to a substantial risk of forfeiture for purposes of Code section 457A (“457A Delivery Date”) occurs prior to the Delivery Date or a Vesting Change in Control, then, in addition to the terms of the Agreement and the Plan, the terms of this Exhibit A shall apply.

    A-1. 457A Delivery Date Prior to a Change in Control. In the event that the Section 457A Delivery Date occurs prior to the date of a Change in Control, the terms of this Section A-1 shall apply.

        (a) Transfer of Vested Shares. If the Section 457A Deliver Date occurs on or after the beginning of the Performance Period, on the 457A Delivery Date, the Participant shall receive a number shares of Stock determined by multiplying (i) the number of Covered Units (which have not previously been forfeited) by (ii) the Performance Percentage determined pursuant to Section 3 as if the Performance Period ended on the later to occur of the 457A Delivery Date and December 1, 2021 (with such percentage converted to a number by dividing such percentage by 100); provided, however, that (A) if the Participant’s Date of Termination occurred on or prior to the 457A Delivery Date due to death, Disability, or a Qualifying Termination, then the product of clauses (i) and (ii) shall additionally be multiplied by the Pro-Rata Fraction or (B) if the Participant’s Date of Termination occurred on or prior to the 457A Delivery Date due to Retirement, then the product of clauses (i) and (ii) shall additionally be multiplied by the Retirement Percentage (with such percentage converted to a number by dividing such percentage by 100). Shares of stock received by a Participant pursuant to this Section A-1 shall be free of restrictions otherwise imposed by this Agreement and the Plan; provided, however, that the shares of Stock shall remain subject to the terms of this Agreement expressly applicable after such Delivery Date (including, without limitation, Section 13); provided, further, however, that the Participant agrees that such shares of Stock cannot be sold or transferred by the Participant at any time prior to the Delivery Date.

        (b) Transfer of Restricted Shares. On the 457A Delivery Date, the Participant shall also receive distribution of shares of Stock that remain subject to the restrictions otherwise imposed by the Plan and this Agreement (including, without limitation, the forfeiture provisions of this Section A-2, the transfer restrictions of Section 9 and the restrictive covenants of Section 13) (such shares of Stock subject to forfeiture and transfer restrictions referred to as the “Restricted Shares”). The number of Restricted Shares to be distributed on the Section 457A Delivery Date shall be determined by multiplying (i) the number of Covered Units (which have not previously been forfeited or cancelled) by (ii) the percentage determined by subtracting the Performance Percentage used for paragraph (a) of Section A-1 above from 200% (with such percentage converted to a number by dividing such percentage by 100); provided, however, that (A) if the Participant’s Date of Termination occurred on or prior to the 457A Delivery Date due to death, Disability, or a Qualifying Termination, then the product of clauses (i) and (ii) shall additionally be multiplied by the Pro-Rata Fraction or (B) if the Participant’s Date of

Termination occurred on or prior to the 457A Delivery Date due to Retirement, then the product of clauses (i) and (ii) shall additionally be multiplied by the Retirement Percentage (with such percentage converted to a number by dividing such percentage by 100). Upon the Performance Determination Date, the number of Restricted Shares which become vested and nonforfeitable and free of all restrictions otherwise imposed by this Agreement (except that the shares of Stock shall remain subject to the terms of this Agreement expressly applicable after the Delivery Date, including, without limitation, Section 13) shall be determined by multiplying (i) the number of Covered Units as used in calculation described in the previous sentence by (ii) the percentage determined by subtracting the Performance Percentage used for paragraph (a) of Section A-1 above from the Performance Percentage determined as of the end of the Performance Period pursuant to Section 3 (as determined by the Committee in writing) (with such percentage converted to a number by dividing such percentage by 100) by (iii), if used in the calculation in the previous sentence, the Pro-Rata Fraction or the Retirement Percentage. Restricted Shares which do not become vested shares of Stock pursuant to the previous sentence shall be forfeited as of the Performance Determination Date. Notwithstanding anything herein to the contrary, if the Participant’s Date of Termination occurred on or prior to the 457A Delivery Date due to a Qualifying Termination, the Restricted Shares shall be immediately forfeited if (i) prior to the last day of the Performance Period, the Participant engages in a Competitive Activity or (ii) the Participant fails to sign and not revoke a general release and waiver of all claims against the Company such that the release is effective within the 60-day period as required by Section 7.1 of the Severance Plan. Notwithstanding anything herein to the contrary, if the Participant’s Date of Termination occurred on or prior to the 457A Delivery Date due to a Retirement, the Restricted Shares shall be immediately forfeited if (i) prior to the last day of the Performance Period, the Participant engages in a Competitive Activity or a Post-Retirement Activity or (ii) the Participant fails to sign and not revoke a general release and waiver of all claims against the Company such that the release is effective within the 60-day period as required by Section 7.1 of the Severance Plan.

    A-2. 457A Delivery Date On or After a Change in Control. In the event that the Section 457A Delivery Date occurs on or after the date of a Change in Control that is not a Vesting Change in Control, the terms of this Section A-2 shall apply. On the 457A Delivery Date, the Participant shall receive a number shares of Stock determined by multiplying (i) the number of Covered Units (which have not previously been forfeited or cancelled) by (ii) the Performance Percentage determined pursuant to Section 3 (with such percentage converted to a number by dividing such percentage by 100); provided, however, that if the Participant’s Date of Termination occurred on or prior to the 457A Delivery Date due to Retirement, then the product of clauses (i) and (ii) shall additionally be multiplied by the Retirement Percentage (with such percentage converted to a number by dividing such percentage by 100). Shares of Stock received by a Participant pursuant to this Section A-2 shall be free of restrictions otherwise imposed by this Agreement and the Plan; provided, however, that the shares of Stock shall remain subject to the terms of this Agreement expressly applicable after such Delivery Date (including, without limitation, Section 13); provided, further, however, that the Participant agrees that such shares of Stock cannot be sold or transferred by the Participant at any time prior to the Delivery Date.

    A-3. Cancellation of Covered Units. As of the 457A Delivery Date, all Covered Units (which have not previously been forfeited or cancelled) shall be cancelled.

    A-4. Dividends. To the extent that the Covered Units have not otherwise been forfeited or cancelled prior to the 457A Delivery Date, the Participant will be paid a cash payment on the 457A Delivery Date equal to the number of shares of Stock delivered pursuant to Sections A-1 and A-2 above, multiplied by the total amount of dividend payments made in relation to one share of Stock with respect to record dates occurring during the period between the Grant Date and the 457A Delivery Date. To the extent that Restricted Shares granted pursuant to this Exhibit A have not otherwise been forfeited or cancelled after the 457A Delivery Date, dividends paid with respect to such Restricted Shares with respect to record dates occurring on or after the 457A Delivery Date of such Restricted Shares shall be used to purchase additional Restricted Shares subject to the same vesting conditions as the original Restricted Shares to which such dividends relate.
