Dear Bob:

This agreement (the
Agreement) sets forth our agreement concerning the terms and conditions of your termination from employment at Ambac Financial Group, Inc. (Ambac or the Company).



|1. | Effective Date of Resignation
|-- | -----------------------------

Your last day of employment with Ambac (the Resignation Date) will be December 31, 2009.



|2. | Employment Period & Payments
|-- | ----------------------------



| | (a) | During the period from the date of this Agreement (Agreement Date or Date of Agreement) through the Resignation Date (the Employment
Period), you will continue to report to Ambacs CEO. You will not be required to report to the office or perform your full-time duties but will be required to provide transition and consulting services to and on behalf of Ambac as
reasonably requested by the CEO or his designee.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | During the Employment Period, you will continue to receive your regular salary at the rate in effect as of June 30, 2009. Such salary will be paid to you in
accordance with Ambacs normal payroll practices and procedures.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Subject to Section 4, you will be paid severance in the amount of $212,000 in consideration of your signing this Agreement. The fee will be paid within ten
business days of the date you execute this Agreement and Waiver and General Release Agreement annexed hereto as Exhibit A on or following the Resignation Date.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3. | Legal and Outplacement Expenses
|-- | -------------------------------

Ambac will pay or reimburse you for up to a total of $25,000 for (i) legal expenses in reviewing this document and (ii) outplacement, career counseling and/or coaching services to be provided to you until the date on which you
secure new employment. You must engage at least the initial provider of such outplacement, career counseling and/or coaching services by March 15, 2010 otherwise you



1



---

forfeit the right to the payment arrangement set forth in clause (ii) of the preceding sentence. The selection of the service providers, dates and scope of services will be as you elect. All
invoices for legal fees and/or outplacement must detail the services provided and must note that the services are for Robert G. Shoback.



|4. | Release Obligations
|-- | -------------------

Ambacs obligations under this Agreement, including its obligation to provide you with the payments set forth in sections 2 and 3, are contingent on the execution, delivery and non-revocation of this Agreement and the Waiver and
General Release Agreement in the form set forth as Exhibit A hereto and, in addition, the execution, delivery and non-revocation, on or as of the Resignation Date, of a second Waiver and General Release Agreement in the form set forth as Exhibit A
hereto in respect of the period from the date you initially sign the Waiver and General Release Agreement through the Resignation Date. In the event the agreement described in the preceding sentence is not executed and delivered, or revoked,
(a) any option and/or restricted stock unit award that has vested from the date hereof through the Resignation Date will be forfeited and (b) you will be required to reimburse Ambac the entire amount of the payments set forth in paragraphs
2 and 3 within ten business days of the revocation date.

Ambac, for and on behalf of itself and the other Released Parties (as
such term is defined in the form of Waiver and General Release Agreement attached hereto as Exhibit A) further hereby waives and releases you and the other Releasors (as such term is also defined in the form of Waiver and General Release Agreement
attached hereto as Exhibit A), from any and all Claims related to any event, condition, circumstance or obligation that occurred, existed or arose on or prior to the date hereof that Ambac is aware of, or should have been aware of, that it or any
other Released Party has, may have or in the future may possess against you or any other such Releasor, arising or accruing on or prior to the date hereof, and Ambac shall, concurrent with your execution and delivery to Ambac on, after or as of the
Resignation Date of the additional Waiver and General Release Agreement, execute and deliver to you a second release in your favor, in a form consistent with and no less favorable to you than the forgoing release set forth in this paragraph,
covering the period between the date Ambac executes this Agreement and the date you execute such second release in favor of Ambac.



|5. | Accrued Obligations
|-- | -------------------

Ambac will timely pay you for any unreimbursed business expenses incurred by you for the period through the Resignation Date in accordance with its normal business expense reimbursement policy, provided, that all of your reimbursable
business expenses are submitted in accordance with Ambacs business expense reimbursement policy. Such reimbursement(s), if any, shall be paid in accordance with Ambacs normal practices and procedures.

---

|6. | Welfare Benefits
|-- | ----------------



| | (a) | Through June 30, 2010, you will continue be eligible to participate in all medical, dental and prescription drug programs available to Ambacs full-time
employees in accordance with the terms of such programs. You will be required to make premium contributions as applicable to all full-time employees with like coverage. If you obtain and commence alternative coverage, you are required to advise
Ambac and terminate the Ambac coverage. During the period through the Resignation Date, you will also continue to receive and participate in all other insurance and employee benefits consistent with past practice.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | Nothing herein contained shall limit any of your rights to elect continuation coverage under Section 4980 (f) of the Internal Revenue Code of 1986, as amended
(relating to COBRA coverage).
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|7. | Retirement Benefits
|-- | -------------------

Through and including the Resignation Date, Company-match and profit-sharing contributions will be credited on your behalf to the Ambac Savings Incentive Plan in accordance with the terms and conditions of such plan at substantially the
same time(s) that the Company funds such contributions for its other employees, regardless of when paid (it being understood that all or a portion of such contributions may be funded on your behalf after the Resignation Date).



|8. | Other Benefits
|-- | --------------

Ambac
will pay you all vested amounts, if any, due but not previously paid to you, pursuant to the terms of any welfare, deferred compensation or other benefit plan as of the Resignation Date, or which by their terms extend to or beyond the Resignation
Date. Notwithstanding the foregoing, any amount due under the Non-Qualified Savings Incentive Plan will be paid to you no sooner than six months and one day from the Resignation Date.

Inasmuch as it is and has been the expressed mutual intention of the parties that your entering into this Agreement shall not affect any or
all of your rights under that certain Amended and Restated Management Retention Agreement, dated as of 2007, between you and Ambac (the Management Retention Agreement), it is agreed that notwithstanding anything to the contrary contained
in this Agreement, in the event that there shall be a Change of Control of Ambac on or prior to the Resignation Date, as such term Change in Control is defined in the Management Retention Agreement, or there shall be a proposed or
pending Change in Control of Ambac reported in any newspaper of general circulation or business publication on or before the Resignation Date, you shall have the right (but not the obligation) to rescind and cancel your Resignation and this
Agreement, together with the related Waiver and General Release Agreement (the form of which is set forth in Exhibit A), as if neither such document had ever been executed (i.e., and such that you shall have no further obligations hereunder or
thereunder), and as if your employment had continued in the ordinary course



3



---

through such date, whereupon the parties hereto shall then promptly cooperate and negotiate, in good faith, a written agreement between them, effective as of such date, such that your employment
with Ambac shall further continue in a manner substantially consistent with past practice and so as to afford you the ability to fully participate in (i.e., and not deprive you from) all of the benefits to which you would otherwise be entitled under
the Management Retention Agreement should the Change in Control be (or have been) consummated. In furtherance of the foregoing, it is understood and agreed that the forfeiture and reimbursement provisions of the first paragraph of Section 4
above would not apply to or with respect to any rescission and/or cancellation by you of this Agreement pursuant to the provisions of this paragraph.

In the event of your death or disability prior to the date any or all payments or benefits under this Agreement shall be paid or become payable to you, all such benefits and payments shall instead be paid
by Ambac to your heirs, executors, administrators, trustees, legal representatives, successors or assigns, as applicable.



|9. | Stock Options and Restricted Stock Units
|-- | ----------------------------------------

As of the date of this Agreement, 43,767 of the Ambac stock options that have been granted to you by the Compensation Committee of Ambac Financial Group, Inc.s Board of Directors are vested. You
will have one year from the Resignation Date or the expiration date of the award, whichever is sooner, to exercise the vested stock options. The terms of the 1997 Equity Plan as Amended and the General Terms and Conditions of the respective stock
option grants shall govern. Any vested options not exercised within the time frame set forth above will be forfeited. All unvested long-term compensation is forfeited.

Restricted stock units that are vested as of the Resignation Date will be settled no sooner than the six month plus one day anniversary of the Resignation Date. The terms of the 1997 Equity Plan as
Amended and the General Terms and Conditions of the respective restricted stock unit grants shall govern. All unvested long-term compensation is forfeited.



|10. | Return of Property
|--- | ------------------

The
parties hereby mutually acknowledge that any Ambac property in your possession and any property made available to you in connection with your employment relationship with Ambac have heretofore been returned by you to Ambac.



|11. | Confidentiality & Competition
|--- | -----------------------------

In consideration for the payments described above, you agree to the following:



| | (a) | Ambac (for purposes of this Section 11, Ambac refers to Ambac and all of its affiliates) is engaged in a highly competitive business and that, in
connection with your employment, you have access to information relating
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | to Ambacs business that provides Ambac with a competitive advantage, that is not generally known by persons not employed by Ambac, and that could not easily be determined or learned by
someone outside Ambac (collectively, Confidential Information). Subject to the foregoing, such Confidential Information may include, but is not limited to, the characteristics and preferences of Ambacs Customers
(as defined below) and accounts, matters relating to information, pricing, fee and commission structures, trading policies and procedures, trade secrets, records, files, memoranda, documents, reports, and other written, printed or recorded materials
and data, regardless of data storage method (collectively Documents) received, created, or used by you during the course of your employment and other methods of doing business, whether or not marketed as confidential or secret. As
used herein, Customer shall mean all clients and actively pursued prospective clients of Ambac with whom or which you actively worked during the period of your employment with Ambac.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | You agree that before and after the Resignation Date, you shall not, directly or indirectly, use or disclose such Confidential Information, except as may be necessary
in the good faith performance of your duties to Ambac. You acknowledge that all Confidential Information will remain the sole property of Ambac and all such documents (if any, that have not yet been returned by you to Ambac) constituting
Confidential Information, other than intellectual knowledge, will be returned by you to Ambac within five business days of the Resignation Date. The terms and conditions of this Section 11(a) and (b) are in addition to and do not supersede
or replace the terms and obligations of Ambacs Code of Business Conduct.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | You further agree that from the Agreement Date through the six-month anniversary of the Resignation Date (i.e., through June 30, 2010), you will not, for any
reason, unless Ambac consents in writing, which consent shall not be unreasonably withheld or delayed, (i) solicit the business of or encourage or assist any other party in competition with Ambac to solicit any such Customer of Ambac in
connection with the municipal bond insurance business, or (ii) assist any party engaged in municipal bond insurance with raising capital for such municipal bond insurance business, or seeking a rating for such municipal bond insurance business
from a Nationally Recognized Statistical Rating Agency, or (iii) hire or seek to hire, whether on your own behalf or on behalf of any other person or entity, any person who is an employee of Ambac at the Resignation Date, or who left the employ
of Ambac within three months prior to such date unless such person was terminated by Ambac.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Paragraph 11(c) and
the associated restrictions contained herein shall supersede and cancel any similar restrictions contained in any and all documents relating to Ambacs stock options and/or restricted stock units, and Ambac hereby waives any objections thereto.

If you breach the terms of this Section 11(c), you forfeit your right to future payments provided for herein from the
date of such breach and, to the extent

any payments have been made, you agree to return all payments made pursuant to this Agreement including, but not limited to, the gross payments provided for in paragraph 2. The return of the
aforementioned payments must be made within ten business days of the breach of this Section 11(c).

In the event that
(A) the Wisconsin Office of the Commissioner of Insurance: (i) appoints a custodian, trustee, agent or receiver for Ambac Assurance Corporation (AAC) or for all or any material portion of its Property or (ii) authorizes
the taking of possession by a custodian, trustee, agent or receiver of AAC (or the taking of possession of all or a substantial portion of AACs property), or (B) Ambac abandons efforts to recapitalize and launch Everspan Financial
Guarantee Corporation, the provisions of this Section 11 will become null and void, except solely for the provisions of the second paragraph of this Section 11(c) which shall remain in full force and effect.

protect the legitimate business interests of Ambac and that Ambac may suffer irreparable harm in the event of any actual or intended violation by you of this paragraph. You, therefore, agree that, in the event of any actual or intended violation by
you of Section 11(b) or 11(c), Ambac shall be entitled to apply for a court order requiring you to cease any such violations in addition to and without prejudice to any other rights or remedies which may be available to Ambac through the legal
system.

| | (f) | You shall not be deemed in breach of the confidentiality obligations set forth in this Section 11 if, compelled by legal process or court order, you are to
participate in any administrative, judicial or criminal investigation, probe, grand jury proceeding or other demand for testimony, information or documentation.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (g) | In the event of any breach of this Section 11, Ambac shall provide you with written notice (to the address set forth on page one of this
Agreement) and you will have ten business days from the date of receipt of said written notice to cure any curable breach. If you fail to cure any such breach or the breach is not curable, Ambac shall be released from any obligation to make any
payment to you or on your behalf and provide any benefits, other than
