(“AGUS”) (the Parent, AGUS, the Company, BCM and their Affiliates collectively referred to as the “Assured Guaranty Group”) are expressly intended to be third party beneficiaries of this Agreement. Reference is made herein to that certain Employment Agreement, dated August 7, 2019 by and between you, the Company and BCM (the “Employment Agreement”). Capitalized terms used but not defined herein shall have the meaning ascribed to such terms in the Employment Agreement.

SECTION 1

RESIGNATION AND TRANSITION

In discussions with the Company, you and the Company have agreed that you will resign as Chief Investment Officer and Head of Asset Management of the Assured Guaranty Group and from all other director or officer positions you hold and from all board and management committees on which you serve in the Assured Guaranty Group, including as an executive officer of Parent and as Chief Executive Officer and Chief Investment Officer of BCM, BlueMountain CLO Management LLC and BlueMountain GP Holdings, LLC (collectively, the “BlueMountain Operating Companies”), effective as of August 6,2020. Subject to the terms of this Agreement, during the period beginning immediately following your resignation and ending on the earlier of (i) October 31, 2020 and (ii) the termination of your employment with the Company in accordance with the terms of this Agreement (such earlier date, the “Separation Date” and such period, 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 and Chief Investment Officer of the BlueMountain Operating Companies (the “BCM CEO”). In such capacity you shall report to the BCM CEO and shall have such duties and responsibilities as may be assigned to you in the reasonable discretion of the BCM CEO, including ensuring an orderly transition of such duties and responsibilities; provided that such duties and responsibilities are not inconsistent with your role as Senior Advisor. Upon the conclusion of the Transition Period you will be deemed to resign, effective as of the Separation Date, from all positions, titles, duties and authorities with the Assured Guaranty Group that you may hold at such time. Notwithstanding the foregoing, the Company may elect to place you on garden leave for all or any part of the Transition Period (such period, the “Garden Leave Period”). During the Garden Leave Period, the other provisions of this Agreement shall continue to have full force and effect and you shall continue to receive the salary and benefits set forth in Section 2.1 of this Agreement and shall continue to carry out any duties for or on behalf of the Assured Guaranty Group as the Company may reasonably request; provided that you shall not be entitled to access any premises of the Assured Guaranty Group without the prior written consent

of the Company. You acknowledge and agree that, for the duration of the Transition Period, you will continue to comply with Section 2(b) of the Employment Agreement. Under no circumstances shall the Company terminate your employment other than for Cause and under no circumstances shall you have any rights to resign from the Company for Good Reason or otherwise (other than due to your Disability). You and the Company expressly acknowledge and agree that the six (6) month notice period required pursuant to Section 6(a) of the Employment Agreement shall be shortened such that it will end on October 31, 2020. Notwithstanding anything herein to the contrary, during and after the Transition Period, you shall continue to serve on the board of directors and/or board of managers of any BlueMountain Funds on which you currently serve unless the Company otherwise requests you resign from any such position, which you shall do upon such direction, provided that following the Transition Period you receive the same compensation and benefits for such non-employee director service as is provided to any similarly situated non-employee director serving on such board..

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 the Separation Date such that the Second Release becomes effective within the sixty-day period following the Separation Date.

SECTION 2

PAYMENTS AND CONSIDERATION

You shall be entitled to compensation, benefits, and consideration from the Company in accordance with this Section 2.

2.1. Amounts Prior to Separation Date.

2.2. Co-Investment and Forfeiture Amount.

(a)Other than as expressly modified herein, you expressly acknowledge and agree that the co-investment obligations set forth in Section 5 of the Employment Agreement (and the rights of the Company relating thereto) will remain in full force and effect until the end of the Co-Investment Required Period. The Company agrees to provide you with updated information, including the specific detailed investment and other information necessary to calculate the Required Investment Amount, on a monthly basis following the date hereof until the expiration of the Co-Investment Required Period, including the specific investments in each fund that give rise to the co-investment obligation. For purposes of determining the Required Investment Amount, separately managed accounts and single-investor investment vehicles shall be excluded from the calculation.

(b)In full satisfaction of your obligation pursuant to Section 5(a)(vi) of the Employment Agreement to transfer to AGUS interests held by you in BlueMountain Funds with a total net asset value equal to the Forfeiture Amount, you shall instead transfer to Parent, on December 31, 2020 or, if unable to do so, as soon as reasonably practicable thereafter, shares of Parent Common Stock held by you with a value equal to the Forfeiture Amount, with the price per share of such Parent Common Stock determined based on the VWAP of Parent Common Stock for the first ten (10) NYSE trading days in the month of December 2020 (such period, the “VWAP Period”). In satisfying your obligations pursuant to the foregoing sentence, you shall (i) first deliver shares of Parent Common Stock held by you, and (ii) to the extent the Forfeiture Amount exceeds the value of the Parent Common Stock held by you and transferred to the Company in accordance with the foregoing clause (i), you shall pay to the Company an amount in cash equal to the excess of the Forfeiture Amount over the value of the Parent Common Stock so transferred (as measured in accordance with this Section 2.2(b)).

The Parties hereby amend the Lock-Up Agreement to reflect the reduction in Parent Common Stock subject to the Lock-Up Agreement as a result of the foregoing and shall negotiate in good faith a revised schedule for the release from the lock-up of the remaining Parent Common Stock, if any, subject to the Lock-Up Agreement. As of the date hereof, the Parties agree that an aggregate of 477,995 shares of Parent Common Stock are subject to the Lock-Up Agreement.

(c)Notwithstanding the foregoing, effective as of the date hereof, (i) the maximum Required Investment Amount shall be reduced from one hundred fifty million dollars ($150,000,000) to one hundred million dollars ($100,000,000) and (ii) the Forfeiture Amount shall be reduced to twelve million dollars ($12,000,000); provided, that in the event you (x) do not sign either the First Release or the Second Release, or revoke your acceptance of the First Release or the Second Release, as applicable, (y) breach this Agreement or Sections 7 or 10 of the Employment Agreement or materially breach Sections 8 or 9 of the Employment Agreement, as determined in accordance with Section 5.3 of this Agreement or (z) do not remain employed until October 31, 2020 (unless your employment ends earlier on account of your death or Disability), then the maximum Required Investment Amount shall immediately be increased from one hundred million dollars ($100,000,000) to one hundred fifty million dollars ($150,000,000).

The Company agrees that if you are made a party or are threatened to be made a party to any action, suit or proceeding, whether civil, criminal, administrative or investigative (a “Proceeding”), by reason of the fact that you are or were a director, officer or trustee of any member of the Assured Guaranty Group or any predecessor of any such member (including, without limitation, the BlueMountain Operating Companies) or are or were serving at the request of any member of the Assured Guaranty Group or any predecessor of any such member (including,

Subject to a customary undertaking to repay such advances as set forth herein, Parent shall advance (or, if Parent shall fail to advance, the Company and/or its Affiliates (other than Parent) shall advance) you all reasonable expenses related to the defense of any such Proceeding. Notwithstanding anything to the contrary in this Section 2.3, no indemnification may be made to you or on your behalf hereunder if a final judgment or other final adjudication adverse to you establishes that your acts or omissions involved fraud, gross negligence, intentional misconduct or a knowing violation of law and in such event you shall be required to immediately repay to Parent the gross amount of any expenses advanced to you in connection with this Section 2.3. The rights and obligations set forth herein shall be in addition to, and not in lieu of, any other rights and obligations you may be entitled to under any other agreements or policies, including without limitation, Parent’s or the Company’s and/or its Affiliates (other than Parent) by-laws and organizational and operating agreements.

SECTION 5

MISCELLANEOUS

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 (including the members of the Assured Guaranty Group as third-party beneficiaries), shall have any rights under or interest in this Agreement or the subject matter hereof. For avoidance of doubt, in the event of your death or Disability, your estate or personal representative, as applicable, shall succeed to any rights under or interest in this Agreement that you may have.

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 (or its Affiliates). Continuation of benefits hereunder by you or the Company (or its Affiliates) following a breach by you or the Company or its Affiliates, as applicable, of any provision of this Agreement shall not preclude you or the Company (or its Affiliates), as applicable, from thereafter exercising any right that you or it may otherwise independently have to terminate said benefits based upon the same violation.

5.3. Effect of Breach. The Company and you acknowledge that the Company or you, as applicable, would be irreparably injured by the Company’s or your violation of Section 3 of this Agreement, and the Company and you agree that the Company and its Affiliates or you, as applicable, in addition to any other remedies available to them or you for such breach or threatened breach, shall be entitled to a preliminary injunction, temporary restraining order, or other equivalent relief, restraining the Company and its Affiliates or you from any actual or threatened breach of Section 3 of this Agreement. If a bond is required to be posted in order for the Company or you to secure an injunction or other equitable remedy, the parties agree that said bond need not be more than a nominal sum. The Company and you acknowledge that each of the covenants contained in Section 3 of this Agreement are an essential part of this Agreement and a condition to the Company’s and your agreement to provide the payments and benefits described in Section 2 of this Agreement. If

-9-

any covenant or term of Section 3 of this Agreement 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 3 of this Agreement 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. For purposes of the foregoing, in order for a party to this Agreement or the Employment Agreement to be in breach of this Agreement or Sections 7 or 10 of the Employment Agreement or in material breach of Sections 8 or 9 of the Employment Agreement, in each case, the non-breaching party must first notify the alleged breaching party in writing, specifying the event alleged to constitute such breach or material breach, as applicable, within ninety (90) days after the non-breaching party first becomes aware of the occurrence of the event the non-breaching party believes constitutes a breach or material breach. The alleged breaching party will then have a period of thirty (30) days after the receipt of such notice in which to cure any acts constituting such breach or material breach (the “Cure Period”), except for a breach or material breach which, by its nature, cannot reasonably be expected to be cured. If the non-breaching party is required to provide notice and the breach or material breach is cured (to the extent it can reasonably be expected to be cured) within this period, the alleged breaching party will be deemed to be in compliance with this Agreement or Sections 7, 8, 9 or 10 of the Employment Agreement, as applicable. The remedies under this Agreement are without prejudice to the rights of the parties hereto to seek any other remedy to which it or you may be entitled at law or in equity.

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).

5.5. Other Agreements. Except for those provisions set forth in the Employment Agreement that survive the termination thereof as or as otherwise specifically provided in this Agreement, this instrument constitutes the entire agreement between you and the Company and its Affiliates 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, the Company, BCM, and you agree that each remains bound by the Lock-Up Agreement and Sections 5, 7, 8, 9, 10, 12, 21, 23, 24 and 25 of the Employment Agreement (in each case, as modified in this Agreement), to the extent applicable; provided, however, Section 12 of the Employment Agreement is hereby modified to provide that any notice to you shall either be (i) personally delivered, sent by reputable overnight courier service, or mailed by first class mail, return receipt requested, and (ii) delivered via e-mail, at the last known home and e-mail addresses the Company has on file for you or such home or e-mail addresses which you provide the Company in writing following the date of this Agreement:

5.6. Governing Law. Sections 18, 19 and 20 of the Employment Agreement are hereby incorporated by reference and made a part of this Agreement as if set forth directly herein; provided, however, that notwithstanding anything in Section 18 of the Employment Agreement to the contrary, the choice of law, for purposes of this Agreement and the Employment Agreement, shall be the internal laws of the State of New York rather than the State of Illinois.

5.7. Agreement Part of Settlement Discussions/No Admission of Liability. The Company and you represent and warrant that any payments or benefits provided to the Company or you, as applicable, under the terms of this Agreement do not constitute an admission by any member of Assured Guaranty Group or you that it or you has violated any law or legal obligation with respect to any aspect of your employment or separation therefrom. If you, the Company, Parent, AGUS or BCM does not accept this Agreement, you or the Company (or its Affiliates), as applicable, acknowledge and agree that the delivery of this Agreement is in contemplation of the settlement of any potential claims you may have against any member of the Assured Guaranty Group or any member of the Assured Guaranty Group may have against you, and will not be admissible for any purpose against any member of the Assured Guaranty Group or against you, and that any payments or benefits contemplated in this Agreement do not constitute an admission by any member of the Assured Guaranty Group or you that it has or you have, as applicable, violated any law or legal obligation with respect to any aspect of your employment or separation therefrom.

5.8 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.

(the “Company”), Assured Guaranty Ltd. (“Parent”) and Assured Guaranty US Holdings Inc. (“AGUS”) (the Parent, AGUS, the Company, BCM and their Affiliates collectively referred to as the “Assured Guaranty Group”).

2.General Release and Waiver of Claims by Executive. In exchange for the Company Releasors’ waiver and release of claims against the Executive Releasees and other good and valuable consideration as provided in the Agreement, Executive, on behalf of himself and the other Executive Releasors, knowingly and voluntarily releases and forever discharges the Company, BCM, Parent, AGUS and the other Company Releasees from any and all Claims which Executive now has or claims, or might hereafter have or claim (or the other Executive Releasors may have, to the extent that it is derived from a Claim which Executive may have), against the Company Releasees based upon or arising out of any matter or thing whatsoever, occurring or arising on or before the date of this Mutual Release and Waiver, including, but not limited to, Claims that arise out of or relate to Executive’s employment by the Company and its Affiliates as defined in the Agreement and/or Executive’s termination or resignation therefrom (“Potential Executive Claims”). However, nothing in this Mutual Release and Waiver shall constitute a release of any Claims of Executive (or other Executive Releasors) for a breach by the Company, Parent, AGUS, and/or BCM of the Agreement; or claims that arise in connection with the Purchase Agreement; or purport to release any Claims which may not lawfully be released. Notwithstanding the foregoing, by executing this Release, Executive hereby confirms that, based upon due inquiry, as of the date hereof, Executive is not aware of any claims against the Company Releasors (as defined below), that are not released by this Section 2, including any claims that arise in connection with the Purchase Agreement. The Company Releasees shall be third-party beneficiaries of this Section 2.

3.Release and Waiver of Claims by Company, BCM, Parent and AGUS. In exchange for Executive’s waiver and release of claims against the Company Releasees and other good and valuable consideration as provided in the Agreement, the Company, BCM, Parent and AGUS, individually and on behalf of their respective Affiliates, (collectively, the “Company Releasors”) knowingly and voluntarily release and forever discharge the Executive Releasees from any and all past and present claims, rights, dues, sums of money, accounts, complaints, judgments, executions, suits, controversies, actions, causes of action, cross-claims, counter-claims, demands, debts, compensatory damages, liquidated damages, punitive or exemplary damages, other damages, claims for costs and attorneys’ fees, or liabilities of any nature whatsoever in law and in equity, which the Company Releasors may have or may hereafter have based upon or arising out of any matter or thing whatsoever, whether known or unknown, occurring or arising on or before the date of this Mutual Release and Waiver, including, but not

limited to, claims which relate to Executive’s employment with any member of the Assured Guaranty Group following the Closing Date and/or Executive’s termination or resignation therefrom (the “Potential Company Claims”); provided, that nothing in this Mutual Release and Waiver shall constitute a release of any claims of the Company Releasors for a breach by the Executive of the Agreement; or claims that arise in connection with the Purchase Agreement; or purport to release any claims which may not lawfully be released. Notwithstanding the foregoing, by executing this Release, each of the Company, Parent, AGUS, and BCM hereby confirm that, based upon due inquiry of the named executive officers of Parent, as of the date hereof, neither the Company, Parent, AGUS, nor BCM is aware of any claims against Executive Releasees not released by this Section 3, including any claims that arise in connection with the Purchase Agreement.

The Assured Guaranty Group and Executive acknowledge that this Agreement does not limit either Party’s right, where applicable, to file or participate in any charge of discrimination or other investigative proceeding of any federal, state or local governmental agency. To the extent permitted by law, if any government agency or court assumes jurisdiction of any charge, complaint, or cause of action covered by this Agreement, each member of the Assured Guaranty Group and Executive will not seek and will not accept any personal, equitable or monetary relief in connection with such investigation, civil action, suit or legal proceeding.
