General Release and Covenant Not to Sue

1.General Release of Claims. In consideration for the payments and benefits paid to you under that certain Agreement, signed by you
and Syncora Holdings Ltd. (the Company), dated October 30, 2008 (the Agreement), you hereby
release and forever discharge the Company and any and all of its affiliates, predecessors, successors, assigns, and their respective officers, directors, administrators and employees (the Released
Parties) of and from all actions, claims, liabilities, demands and causes of action, known or unknown, fixed or contingent, in law or equity, included but not limited to those arising under the Civil Rights
Act of 1964, the Reconstruction Era Civil Rights Act, the Age Discrimination in Employment Act of 1967 (ADEA), the Consultant Retirement Income Security Act of 1974, The Americans with Disabilities Act, The Family and Medical Leave Act
of 1993, The New York State Human Rights Law Section 196 ET SEQ., the New York City Administrative Code, as amended, and any and all other federal, state, and local laws, rules and regulations prohibiting, without limitation, discrimination in
employment, tortuous or wrongful discharge, breach of an express or implied contract, breach of a covenant of good faith and fair dealing, negligent or intentional infliction of emotional distress, defamation, misrepresentation or fraud, which you
ever had, now have or hereafter can, shall or may have for, upon or by reason of any matter, cause or thing, up to and including the day on which you sign this Agreement (the Claims); provided, however, that you are not waiving (a) any rights under the Agreement, (b) any right to claim benefits under employee benefit plans (including welfare benefit, retirement and (except as set forth in the Agreement)
equity-related plans), (c) any right of indemnification (including indemnification, legal defense and related rights under the Companys certificate of incorporation, by-laws or other such organic documents), or (d) any rights under directors
and officers liability insurance policies.

2.Effect of General Release; Limitations on General Release. You understand that by signing this General Release you are prevented
from filing, commencing or maintaining any action, complaint, or proceeding with regard to any of the claims released hereby. However, nothing in the General Release of Claims above precludes you from filing a charge with an administrative agency or
from participating in an agency investigation. You are, however, waiving your right to recover money in connection with any such charge or investigation. You are also waiving your right to recover money in connection with a charge filed by any other
individual or by the Equal Employment Opportunity Commission or any other federal or state agency.

3.Covenant Not to Sue. In addition to waiving and releasing the claims and rights covered by the General Release of Claims, you
promise not to sue the Company or any other Released Party in any forum on any claim which is covered by (i.e., released under) the General Release of Claims. This covenant by you not to sue is different from the General Release of Claims, which
will provide the Company a defense in the event

---



you violate the General Release. If you violate this Covenant Not to Sue by suing a Released Party, you may be liable to that party for monetary damages. More specifically, if you sue a Released Party in violation of this Covenant
Not to Sue, you will be required to either: (1) pay that Released Partys attorneys fees and other costs incurred as a result of having to defend against your suit; or (2) alternatively, at the Released Partys option, return to the
Company all of the severance pay provided to you under Section 8 of the Employment Agreement and under the Agreement, except for one-hundred dollars ($100.00) . In the event of such violation, the Company will also be excused from providing you
any remaining severance payments under Section 8 of the Employment Agreement and under the Agreement. However, nothing in this Covenant Not to Sue or in any other part of this Agreement prevents you from challenging the validity of this Agreement
under the ADEA.

4.Knowing and Voluntary Decision to Sign. You further agree that no statements, representations, promises, threats or suggestions
have been made by the Company or its representatives, officers, or employees to influence you to sign this General Release except such statements as are expressly set forth herein. You have signed this General Release upon reaching the considered
conclusion that it is best for you, and of your own free will, relying entirely upon your own judgment, and the judgment of such lawyers and other personal advisors who you have chosen to consult. You further acknowledge that you are under no
disability or impairment, which affects your decision to sign this General Release.

5.Time to Consider the Agreement. You have actually read this General Release, and have had adequate time of at least 21 days to
consider its terms and effect, and to ask any questions that you may have of the legal or other personal advisors of your own choosing. You may revoke this General Release during the seven day period following its execution by providing written
notice of such revocation to the Company.

6.Subsequent Facts. No fact, evidence, event or transaction currently unknown to you but which may hereafter become known to you
shall affect in any way or manner the final and unconditional nature of this General Release.
