 You will be eligible to participate in Russell’s long-term incentive program, which
includes the fiscal year 2004-2005 Performance Share Award Program which includes performance shares and time lapse restricted shares. You will receive a grant of 1,500 shares of which 1,200 are performance based and 300 will vest at the end of the

 (d) No Base Rate Advance may be borrowed in a Currency other than Dollars. 
  
 SECTION 2.02 Making the Advances. (a) Each Borrowing shall be made on notice, given not later than 12:00 Noon (New York City time) (or, in the case
of a Borrowing in an Alternate Currency, London time) on the third Business Day next preceding the date of such Borrowing in the case of a Borrowing consisting of Eurocurrency Rate Advances, or 11:30 A.M. (New York City time) on the Business Day of
the proposed Borrowing in the case of a Borrowing consisting of Base Rate Advances, by either Borrower to the Administrative Agent, which shall give to each Lender prompt notice thereof by telecopier. Each such notice of a Borrowing (a

 15 

 
such Borrowing, (ii) Currency and Type of Advances comprising such Borrowing, (iii) aggregate amount of such Borrowing and (iv) in the case of a Borrowing
consisting of Eurocurrency Rate Advances, initial Interest Period for each such Advance. Each Lender shall, before 10:00 A.M. (Local Time) on the date of such Borrowing in the case of a Borrowing consisting of Eurocurrency Rate Advances, or 1:00
P.M. (New York City time) on the date of such Borrowing in the case of a Borrowing consisting of Base Rate Advances, make available for the account of its Applicable Lending Office to the Administrative Agent at the Administrative Agent’s
Account for the relevant Currency, in same day funds, such Lender’s ratable portion of such Borrowing. After the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the

Borrowing consisting of Base Rate Advances, make such funds available to such Borrower at the Administrative Agent’s address referred to in Section 8.02. 
  

(b) Anything in subsection (a) above to the contrary notwithstanding, neither Borrower may select Eurocurrency Rate Advances for any
Borrowing if the obligation of the Lenders to make Eurocurrency Rate Advances shall then be suspended pursuant to Section 2.07 or 2.11. 
  
 (c) In the case of any Borrowing that the related Notice of Borrowing specifies is to be comprised of Eurocurrency Rate Advances, the

applicable conditions set forth in Article III, including any loss (excluding loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Advance
to be made by such Lender as part of such Borrowing when such Advance, as a result of such failure, is not made on such date. 
  
 (d) Unless the Administrative Agent shall have received notice from a Lender prior to the date of any Borrowing that such Lender will not
make available to the Administrative Agent such Lender’s ratable portion of such Borrowing, the Administrative Agent may assume that such Lender has made such portion available to the Administrative Agent on the date of such Borrowing in
accordance with subsection (a) of this Section 2.02 and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower that has requested such Borrowing on such date a corresponding amount. If and to the extent that
such Lender shall not have so made such ratable portion available to the Administrative Agent, such Lender and such Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest
thereon, for each day from the date such amount is made available to such Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of such Borrower, the interest rate applicable at the time to Advances comprising
such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Lender’s Advance as part of such Borrowing
for purposes of this Agreement. 
  

 16

Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its Advance on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other
Lender on the date of any Borrowing.

Advance denominated in such Alternate Currency is made, as the Dollar Equivalent of the principal amount of such Advance denominated in such Alternate Currency outstanding on such day) exceeds 50% of the aggregate amount of Commitments, computed at

amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the Eurocurrency Rate for the then existing Interest Period for such Advance from (ii) the rate obtained by dividing such
Eurocurrency Rate by a percentage equal to 100% minus the Eurocurrency Rate Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest is payable on such Advance. Each Lender shall, as promptly as
practicable after an authorized officer of such Lender having direct and ongoing involvement in the decisions made in respect of this Agreement obtains knowledge of such circumstances and the determination of such Lender to request additional
interest from such Borrower pursuant to this Section 2.06(b), provide notice to the Administrative Agent and such Borrower of the circumstances entitling such Lender to such additional interest, which notice shall (A) specify the amount of any such
additional interest incurred in connection with such Eurocurrency Rate Advance made to such Borrower and/or to be incurred in connection with Eurocurrency Rate Advances made by such Lender from time to time thereafter to such Borrower and (B)
certify that such Lender’s claim for payment of such additional interest is not inconsistent with its treatment of other borrowers that, as a credit matter, are substantially similar to such Borrower and that are subject to comparable
provisions in the loan or other credit documentation to which such borrowers are parties; provided, however, that no Lender shall be entitled to additional interest on any Eurocurrency Rate Advance pursuant to this Section 2.06(b) for
any Interest Period ending more than 120 days prior to the date that notice of such additional interest is first 

  

 18 

 
provided by such Lender to such Borrower. A notice delivered by any Lender to either Borrower pursuant to the terms of this Section 2.06(b) shall be
conclusive and binding, absent manifest error. A Lender that delivers a notice under this Section 2.06(b) shall promptly notify the Administrative Agent and such Borrower if the circumstances that gave rise to such notice no longer exist.

  
 (c) MCR Costs. Each Borrower shall pay
additional interest on the unpaid principal amount of each Eurocurrency Rate Advance denominated in an Alternate Currency made to such Borrower, from the date of such Advance until such principal amount is paid in full, at an interest rate per annum
equal at all times to the MCR Cost (if any) in respect of such Advance, payable on each date on which interest is payable on such Advance. 
  
 SECTION 2.07 Interest Rate Determination. (a) The Administrative Agent shall give prompt notice to each Borrower and the Lenders of the applicable
interest rate determined by the Administrative Agent for purposes of Section 2.06(a). 
  
 (b) If either Borrower shall fail to select the duration of any Interest Period for any Eurocurrency Rate Advances to be made to such
Borrower in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01, such Interest Period shall have a duration of one month. 
  
 (c) On the date on which the aggregate unpaid principal amount of Eurocurrency Rate Advances denominated in
Dollars having the same Interest Period shall be reduced, by payment or prepayment or otherwise, to less than $5,000,000, such Advances shall automatically, on the final day of the then existing Interest Period therefor, Convert into Base Rate
Advances. 
  
 (d) Upon the occurrence and during
the continuance of any Event of Default, (i) each Eurocurrency Rate Advance denominated in Dollars will automatically, on the final day of the then existing Interest Period therefor, Convert into a Base Rate Advance and (ii) the obligation of the
Lenders to Convert Base Rate Advances into Eurocurrency Rate Advances denominated in Dollars shall be suspended. 
  
 SECTION 2.08 Optional Conversion of Advances. Each Borrower may on any Business Day, upon notice given to the Administrative Agent not later than
12:00 A.M. (New York City time) on the third Business Day prior to the date of the proposed Conversion and subject to the provisions of Sections 2.07 and 2.11, Convert all Base Rate Advances made to such Borrower comprising the same Borrowing into
Eurocurrency Rate Advances denominated in Dollars and Convert all Eurocurrency Rate Advances denominated in Dollars made to such Borrower comprising the same Borrowing into Base Rate Advances; provided, however, that (a) any Conversion
of Eurocurrency Rate Advances denominated in Dollars into Base Rate Advances shall be made only on the final day of an Interest Period for such Eurocurrency Rate Advances and (b) no Conversion of any Advances shall result in more separate Interest
Periods with respect to Eurocurrency Rate Advances denominated in Dollars made to such Borrower than permitted under the definition of the term “Interest Period” in Section 1.01; and provided, further, that no Base Rate
Advance may be Converted to a Eurocurrency Rate Advance denominated in Dollars when any Event of Default has occurred and is continuing. Each such 

  

 19 

 
notice of a Conversion shall, within the restrictions specified above, specify (i) the date of such Conversion, (ii) the Advances to be Converted, and (iii)
if such Conversion is into Eurocurrency Rate Advances denominated in Dollars, the duration of the initial Interest Period for each such Advance. Each notice of Conversion shall be irrevocable and binding on the Borrowers. 
  
 SECTION 2.09 Prepayments. (a) Optional. Each Borrower may, in
the case of Eurocurrency Rate Advances upon at least two Business Days’ notice, or, in the case of Base Rate Advances upon same day notice, to the Administrative Agent (which shall promptly notify each Lender) stating the proposed date and
aggregate principal amount of the prepayment, and if such notice is given, such Borrower shall, prepay the outstanding principal amount of the Advances made to such Borrower comprising part of the same Borrowing in whole or ratably in part, together
with accrued interest to the date of such prepayment on the principal amount prepaid; provided, however, that all such partial prepayments shall be in an aggregate minimum amount of $10,000,000 or an integral multiple of $1,000,000 in
excess thereof (or in each case the Alternate Currency Equivalent thereof computed as of the day two Business Days before such prepayment is made). Each prepayment of any Advances made pursuant to this Section 2.09 shall be without premium or
penalty, subject, however, to Section 8.04(c). 
  
 (b) Mandatory. 
  
 (i) If on the
last day of any Interest Period, by reason of fluctuation of exchange rates between Alternate Currencies and the Dollar, (1) the aggregate outstanding principal amount of all Advances (computed as of such day, in the case of Advances denominated in
an Alternate Currency, as the Dollar Equivalent of such Advances) exceeds (2) an amount equal to 105% of the aggregate amount of the Commitments then in effect, the Administrative Agent shall use all reasonable efforts to give prompt written notice
thereof to the Borrowers, specifying the amount to be prepaid by the Borrowers under this clause (i), so that, after giving effect to such prepayment by the Borrowers, the aggregate principal amount of the Advances outstanding to both Borrowers
(determined as aforesaid) does not exceed the aggregate amount of the Commitments and, if the Administrative Agent shall give each of the Borrowers such notice, the Borrowers shall, within five Business Days after receipt by the Borrowers of such
notice, prepay the Advances in an aggregate principal amount equal to the amount set forth in such notice by the Administrative Agent. 
  
 (ii) The determinations of the Administrative Agent under this Section 2.09(b) shall be conclusive and binding on the Borrowers in the
absence of manifest error. 
  
 SECTION 2.10 Increased
Costs. If, due to either (a) the introduction of or any change (other than any change by way of imposition or increase of reserve requirements included in the Eurocurrency Rate Reserve Percentage), after the date hereof in, or any change after
the date hereof in the interpretation of, any law or regulation or (b) the compliance with any guideline or request promulgated after the date hereof from any central bank or other governmental authority (whether or not having the force of law),
there shall be any increase in (i) the cost to any Lender of agreeing to make or making, funding or maintaining Eurocurrency Rate Advances (excluding for purposes of this Section 2.10 any such increased costs resulting from Taxes or Other Taxes or
from changes in the basis or rate of taxation of net income or gross 

  

 20 

 
income by the United States or by the foreign jurisdiction or state under the laws of which such Lender is subject to tax as a result of a present or former
connection between such Lender and such foreign jurisdiction or state) or (ii) the amount of capital required to be maintained by such Lender or any corporation controlling such Lender based on the existence of its Commitment or the Advances
hereunder, then the Borrowers jointly and severally agree from time to time, within five Business Days after receipt by both Borrowers of a written demand by such Lender (with a copy of such demand to the Administrative Agent), to pay to the
Administrative Agent for the account of such Lender additional amounts as shall accrue from and after the date of demand by such Lender to compensate such Lender (or such controlling corporation, as the case may be) for such increased cost or such
increase of capital; provided, however, that before making any such demand, each Lender agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to minimize such additional amounts
and to designate a different Applicable Lending Office if the making of such a designation would avoid the need for, or reduce the amount of, such increased cost or such increase of capital and would not, in the reasonable judgment of such Lender,
be otherwise disadvantageous to such Lender; and provided, further, that the Borrowers shall be required jointly and severally to pay to such Lender only such additional amounts as shall be required to compensate such Lender for such
increased cost or such increase of capital as shall accrue from and after the date of demand by such Lender. In determining such additional amounts, such Lender will act reasonably and in good faith and will use averaging and attribution methods
which are reasonable, provided that such Lender’s determination of compensation owing under this Section 2.10 shall be conclusive and binding, absent manifest error. Each Lender, upon determining that any additional amounts will be
payable pursuant to this Section 2.10, will give prompt written notice thereof to the Borrowers, which notice shall show the basis for the calculation of such additional amounts. Notwithstanding anything herein to the contrary, either Borrower shall
have the right to unilaterally terminate the Commitment of any Lender demanding additional amounts under this Section 2.10 sixty (60) days after providing to such Lender a notice of termination; provided that such termination shall not result
in a reduction in amounts required to be paid pursuant to this Section 2.10. Each of the Borrowers shall, concurrently with such termination, pay or prepay, as the case may be, to such Lender the aggregate amount, if any at such time, of all
Advances and other amounts payable by such Borrower to such Lender under this Agreement. Notwithstanding any provision of this Agreement to the contrary, Section 2.13 shall provide the exclusive remedy to the Lenders in respect of Taxes and Other
Taxes. 
  
 SECTION 2.11 Illegality. Notwithstanding any
other provision of this Agreement, if any Lender shall notify the Administrative Agent that the introduction of or any change after the date hereof in or in the interpretation of any law or regulation makes it unlawful, or any central bank or other
governmental authority asserts after the date hereof that it is unlawful, for any Lender or its Eurocurrency Lending Office to perform its obligations hereunder to make Eurocurrency Rate Advances or to fund or maintain Eurocurrency Rate Advances
hereunder, (i) each Eurocurrency Rate Advance denominated in Dollars will automatically, upon such demand, Convert into a Base Rate Advance and (ii) the obligation of the Lenders to Convert Base Rate Advances into Eurocurrency Rate Advances
denominated in Dollars shall be suspended until the Administrative Agent shall notify the Borrower that has requested such Advance and the Lenders that the circumstances causing such suspension no longer exist; provided, however, that
before making any such demand, each Lender agrees to use reasonable 

  

 21 

 
efforts (consistent with its internal policy and legal and regulatory restrictions) to designate a different Eurocurrency Lending Office if the making of
such a designation would allow such Lender or its Eurocurrency Lending Office to continue to perform its obligations to make Eurocurrency Rate Advances or to continue to fund or maintain Eurocurrency Rate Advances and would not, in the reasonable
judgment of such Lender, be otherwise disadvantageous to such Lender. 
  
 SECTION 2.12 Payments and Computations. 
  
 (a) All payments of principal and of interest on any Advance denominated in Dollars and of all facility fees, agency fees and utilization fees shall be made in Dollars and in immediately available funds. 

 
 (b) All payments of principal and interest on any Advance
denominated in an Alternate Currency shall be made in such Currency and in immediately available funds. 
  
 (c) Each Borrower shall make each payment to be made by it hereunder and under the Notes to the Administrative Agent at the Administrative
Agent’s Account in the Principal Financial Center for the relevant Currency in immediately available funds, not later than 11:00 A.M. Local Time on the day when due and without set-off or counterclaim. The Administrative Agent will promptly
thereafter cause to be distributed like Currency and funds relating to the payment of principal, interest or fees ratably (other than amounts payable pursuant to Section 2.10, 2.13 or 8.04(c)) to the Lenders for the account of their respective
Applicable Lending Offices, and like Currency and funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of
this Agreement. Upon its acceptance of an Assignment and Acceptance and recording of the information contained therein in the Register pursuant to Section 8.07(d), from and after the effective date specified in such Assignment and Acceptance, the
Administrative Agent shall make all payments hereunder and under the Notes in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in
such payments for periods prior to such effective date directly between themselves. 
  
 (d) All computations of interest based on the Base Rate, when the Base Rate is determined by reference to Citibank’s base rate, shall
be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all other computations of interest and of facility fees and utilization fees shall be made by the Administrative Agent on the basis of a year of
360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Administrative Agent of an interest rate
hereunder shall be conclusive and binding, absent manifest error. 
  
 (e) Whenever any payment hereunder or under the Notes shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in
such case be included in the computation of payment of interest, facility fee or utilization fee, as the case may be; provided, however, that, if such extension would cause payment of interest on or principal of Eurocurrency Rate
Advances 

  

 22 

 
to be made in the next succeeding calendar month, such payment shall be made on the next preceding Business Day. 
  
 (f) Unless the Administrative Agent shall have received
notice from either Borrower prior to the date on which any payment is due to the Lenders hereunder that such Borrower will not make such payment in full, the Administrative Agent may assume that such Borrower has made such payment in full to the
Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent such Borrower
shall not have so made such payment in full to the Administrative Agent, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such
amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate. 
  
 SECTION 2.13 Taxes. (a) Any and all payments by each Borrower hereunder or under the Notes shall be made, in accordance with Section 2.12, free and
clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings imposed by the United States or by any political subdivision thereof or therein with respect to such payments, and all
penalties and interest with respect thereto, excluding, in the case of each Lender and the Administrative Agent, taxes imposed on or measured by its net income or net profit, and branch profit taxes, franchise taxes, taxes on doing business
and taxes measured by or imposed upon its capital or net worth, in each case imposed as a result of a present or former connection between the Administrative Agent or such Lender and the jurisdiction imposing such tax or any political subdivision or
taxing authority thereof or therein (other than any such connection arising solely from the Administrative Agent or such Lender having executed, delivered or performed its obligations or received a payment under, or enforced this Agreement or the
Notes) (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect of payments hereunder or under the Notes being hereinafter referred to as “Taxes”). If either Borrower shall be
required by law to deduct any Taxes from or in respect of any sum payable by such Borrower hereunder or under any Note to any Lender or the Administrative Agent, (i) the sum payable shall be increased as may be necessary so that after making all
required deductions (including deductions applicable to additional sums payable under this Section 2.13) such Lender or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions
been made, (ii) such Borrower shall make such deductions and (iii) such Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law. 
  
 (b) In addition, the Borrowers jointly and severally agree
to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from the execution, delivery or registration of this Agreement or the Notes (hereinafter referred to as
“Other Taxes”); provided, however, that the Borrowers shall have no obligation to pay Other Taxes that may arise as a result of a participation referred to in Section 2.14 or 8.07. 
  

 23 

 (c) Each of the Borrowers shall indemnify each Lender and the Administrative Agent for
and hold it harmless against the full amount of Taxes with respect to payments by such Borrower hereunder or under the Notes imposed on or paid by such Lender or the Administrative Agent (as the case may be) and any liability for penalties, interest
and expenses arising therefrom or with respect thereto. The Borrowers shall jointly and severally indemnify each Lender and the Administrative Agent for and hold it harmless against the full amount of Other Taxes imposed on or paid by such Lender or
the Administrative Agent (as the case may be) and any liability for penalties, interest and expenses arising therefrom or with respect thereto. Any indemnification under this Section 2.13(c) shall be made within 30 days from the date such Lender or
the Administrative Agent (as the case may be) makes written demand therefor. 
  
 (d) Each Lender that is not a “United States person” within the meanings specified in Section 7701 of the Code, on or prior to the date of its execution and delivery of this Agreement or on the date of the
Assignment and Acceptance pursuant to which it becomes a Lender, as the case may be, and from time to time thereafter as requested in writing by either Borrower (but only so long as such Lender remains lawfully able to do so), shall provide each of
the Administrative Agent and such Borrower with (i) two accurate and complete original signed copies of Internal Revenue Service Form W-8BEN or W-8ECI, as appropriate, or any successor or other form prescribed by the Internal Revenue Service,
certifying to such Lender’s entitlement to a complete exemption from United States withholding tax with respect to payments to be made under this Agreement or the Notes on account of such Lender being entitled to benefits under an income tax
treaty or such payments being effectively connected with such Lender’s conduct of a United States trade or business or (ii) if the Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code and cannot deliver either
Internal Revenue Service Form W-8BEN or W-8ECI pursuant to clause (i) above, (A) a certificate in form and substance satisfactory to the Administrative Agent and such Borrower stating that such Lender is not a “person” described in Section
871(h)(3) or Section 881(c)(3) of the Code (a “Foreign Lender Certificate”) and (B) two accurate and complete original signed copies of Internal Revenue Service Form W-8BEN (or successor form) certifying to such Lender’s
entitlement to a complete exemption from United States withholding tax with respect to payments to be made under this Agreement and under any Note. In addition, each Lender agrees that from time to time, when a lapse in time or change in
circumstances renders the previous certification obsolete or inaccurate in any material respect, it will deliver to such Borrower and the Administrative Agent two new accurate and complete original signed copies of Internal Revenue Service Form
W-8BEN or W-8ECI, or Form W-8BEN and a Foreign Lender Certificate, as the case may be, and such other forms as may be required in order to confirm or establish the entitlement of such Lender to a continued exemption from United States withholding
tax with respect to payments under this Agreement and any Note or it shall immediately notify such Borrower and the Administrative Agent of its inability to deliver any such form or certificate, in which case such Lender shall not be required to
deliver any such form or certificate pursuant to this Section 2.13(d) for so long as such payments may be made free from United States withholding tax. Notwithstanding the foregoing, no Lender shall be required to deliver any such form or
certificate described in the immediately preceding sentence if a change in treaty, law or regulation has occurred prior to the date on which such delivery would otherwise be required that renders any such form or 

  

 24 

 
certificate inapplicable or would prevent the Lender from duly completing and delivering any such form or certificate with respect to it and such Lender so
advises such Borrower. 
  
 (e) For any period
with respect to which a Lender has failed to provide either Borrower with the appropriate form described in Section 2.13(d), such Lender shall not be entitled to indemnification under Section 2.13(a) or (c) with respect to Taxes or Other Taxes
imposed by the United States by reason of such failure. 
  
 (f) Any Lender claiming additional amounts payable pursuant to this Section 2.13 agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to minimize such additional
amounts and to change the jurisdiction of its Applicable Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable
determination of such Lender, be otherwise disadvantageous to such Lender. 
  
 (g) If a Lender changes its Applicable Lending Office (other than pursuant to subsection (f) above or Section 2.11 or 2.12 or otherwise at the request of either Borrower) and the effect of such change, as of the date
of such change, would be to cause either Borrower to become obligated to pay any additional amounts under this Section 2.13, such Borrower shall not be obligated to pay such additional amounts. 
  
 (h) If either Borrower is required to pay any amounts
pursuant to the provisions of this Section 2.13 to or for the account of any Lender or the Administrative Agent, and if thereafter such Lender or the Administrative Agent, as the case may be, shall receive a refund of any Taxes or Other Taxes paid
by or on behalf of such Lender or the Administrative Agent, as the case may be, that such Lender or the Administrative Agent, as the case may be, reasonably determines to relate solely to the amounts so paid by such Borrower, such Lender or the
Administrative Agent, as the case may be, shall to the extent that it can do so without prejudice to the retention of the amount of such refund, pay to such Borrower within twenty days after the date on which such Lender or the Administrative Agent,
as the case may be, actually receives such refund in an amount which such Lender or the Administrative Agent, as the case may be, determines to be the proportion of the refunded amount as will leave it, after such remittance, in no better or worse
position than it would have been if the Taxes or Other Taxes had not been imposed and the corresponding additional amounts or indemnification payment not been made. Nothing in this Section 2.13(h) shall be construed as requiring any Lender or the
Administrative Agent to conduct its business or to arrange or alter in any respect its tax or financial affairs so that it is entitled to receive such refund. Neither a Lender nor the Administrative Agent shall be obligated to disclose information
regarding its tax affairs or computations to either Borrower in connection with this clause (h). 
  
 SECTION 2.14 Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) on account of the Advances owing to it (other than pursuant to Section 2.10, 2.13 or 8.04(c)) in excess of its ratable share of payments on account of the Advances obtained by all the Lenders, such Lender shall forthwith
purchase from the other Lenders such participations in the Advances owing to them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any
portion of such 

  

 25 

 
excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the
purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such Lender’s ratable share (according to the proportion of (a) the amount of such Lender’s required repayment to (b) the total amount so
recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrowers agree that any Lender so purchasing a participation from another Lender
pursuant to this Section 2.14 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of either Borrower
in the amount of such participation. 
  
 SECTION 2.15 Use of
Proceeds. Each Borrower shall use the proceeds of each Advance for working capital and general corporate or company purposes of such Borrower and its Subsidiaries. 
  
 SECTION 2.16 Increase of Commitments. (a) The Borrowers may, at any time but in any event not more than two times
during any calendar year, make a written request (an “Increase Request”) to the Administrative Agent (who shall forward a copy to each Lender) that the Commitments of the Lenders be increased, in integral multiples of $15,000,000,
by an aggregate amount, together with the aggregate amount by which the Commitments of the Lenders were previously increased pursuant to this Section 2.16, not to exceed $100,000,000 in excess of the aggregate amount of the Commitments as of the
date of this Agreement. Such Increase Request shall include a certification by a senior officer of each Borrower that (i) on and as of the date of the Increase Request and after giving effect to the requested increase in Commitments, Ambac
Financial’s long-term senior unsecured non-credit-enhanced debt ratings by Moody’s and S&P are better than or equal to Aa3 and AA-, respectively, and (ii) no Default has occurred and is continuing and all representations and warranties
contained herein are true and correct in all material respects on and as of the date of the Increase Request, including without limitation the representation and warranty of the Borrowers as to the execution, delivery and performance by them of this
Agreement and the Notes, taking into account such increase, having been duly authorized by all necessary corporate action (it being understood and agreed that any representation or warranty which expressly refers by its terms to a specified date
shall be required to be true and correct in all material respects only as of such date). Any such increase in Commitments shall be effective as of a date (the “Increase Date”) specified in the related Increase Notice that is (i)
prior to the Commitment Termination Date and (ii) at least 10 days after the date of such Increase Notice. Each Increase Notice shall specify the date by which Lenders who wish to increase their Commitments must consent to such increase (the
“Commitment Date”), which date shall be no later than five Business Days prior to the related Increase Date. Each Lender that is willing to increase its Commitment (each an “Increasing Lender”), shall notify the
Administrative Agent on or prior to the Commitment Date of the amount by which it is willing to increase its Commitment, which amount shall not exceed the respective amount specified in the relevant Increase Notice. No Lender shall be obligated to
increase its Commitment pursuant to this Section 2.16 and any such increase shall be in the sole discretion of each Lender. If the Lenders notify the Administrative Agent that they are willing to increase the amount of their respective Commitments
by an aggregate amount that exceeds the amount of the requested increase, the requested increase shall be allocated among the Lenders 

  

 26 

 
willing to participate therein ratably in accordance with the amount by which they offered to increase their respective Commitments on the Commitment Date.

  
 (b) Promptly following each Commitment Date,
the Administrative Agent shall notify the Borrowers as to the amount, if any, by which the Lenders are willing to participate in the requested increase. If the aggregate amount by which the Lenders are willing to increase their Commitments on any
such Commitment Date is less than the requested amount, then any one or more Eligible Transferees designated by the Borrowers that agree to provide Commitments for the shortfall may become party to this Agreement by executing and delivering,
together with the Borrowers, an accession agreement pursuant to which such Eligible Transferee shall become a party to this Agreement and, to the extent provided therein, shall have the rights and obligations of a Lender hereunder; provided
that each such Eligible Transferee shall provide a Commitment in a minimum amount of $10,000,000 or an integral multiple of $1,000,000 in excess thereof. 
  
 (c) On each Increase Date, (i) each Eligible Transferee that accepts an offer to participate in a requested Commitment increase in
accordance with Section 2.16(b) shall become a Lender party to this Agreement as of such Increase Date and the Commitment of each Increasing Lender shall be increased as of such Increase Date by the amount set forth in its notice delivered to the
Administrative Agent in accordance with Section 2.16(a) (or by the amount allocated to such Lender pursuant to the last sentence of Section 2.16(a)) and (ii) if on such date there are Advances outstanding, appropriate adjustments shall be made among
the Lenders to cause the outstanding Advances to be held ratably by all Lenders in accordance with their respective Commitments as of the Increase Date. As soon as practicable after the Increase Date, Notes (to the extent requested by Increasing
Lenders and Eligible Transferees) shall be issued to reflect the respective Commitments of any such Increasing Lenders and Eligible Transferees. 
  
 SECTION 2.17 Right to Replace a Lender. If either Borrower is required to make any additional payment pursuant to Section 2.10 or 2.13 to any
Lender or if any Lender’s obligation to make, or to Convert Advances into, Eurocurrency Rate Advances shall be suspended pursuant to Section 2.11 (in each case, such Lender being an “Affected Person”), the Borrowers may elect,
if such amounts continue to be charged or such suspension is still effective, to replace such Affected Person as a party to this Agreement, provided that no Default shall have occurred and be continuing at the time of such replacement and,
provided, further, that concurrently with such replacement, (i) one or more Eligible Transferees reasonably satisfactory to the Borrowers and the Administrative Agent shall agree, as of such date, to become a Lender for all purposes
under this Agreement and to assume all obligations (including the Commitment) of the Affected Person to be terminated as of such date and to comply with the requirements of Section 8.07 applicable to assignments, (ii) such Affected Person shall have
received payment of all amounts then due and owing to such Affected Person hereunder to and including the date of termination, including without limitation payments due such Affected Person under Section 2.10 and 2.13, and (iii) such Borrower shall
pay to the Administrative Agent an administrative fee in the amount of $3,500 for each such replacement in the event that the replacing Lender in respect thereof is not a Lender at the time of such replacement.

 REPRESENTATIONS AND WARRANTIES

Borrower represents and warrants as follows: 
  
 (a) Each Borrower and each of its Material Subsidiaries (i) is a limited liability company, corporation or partnership, as the case may be, duly formed or organized and existing and in good standing under the laws of the jurisdiction of its
formation or organization, as the case may be, (ii) is duly registered or qualified to do business as a foreign limited liability company, corporation or partnership, as the case may be, in each jurisdiction where the nature of its business requires
such registration or qualification and (iii) holds all requisite governmental licenses, permits and other approvals to own and hold under lease its property and to conduct its business substantially as conducted by it, except where the failure to be
so qualified or hold such licenses, permits and approvals, singly or in the aggregate, could not reasonably be expected to have a Material Adverse Effect. 
  
 (b) The execution, delivery and performance by each Borrower of each Loan Document to which it is party are within such Borrower’s
corporate powers, have been duly authorized by all necessary corporate action, and do not (i) contravene such Borrower’s certificate of incorporation or by-laws; (ii) contravene any contractual restriction, law or governmental regulation or
court decree or order binding on or affecting such Borrower; or (iii) result in, or require the creation or imposition of, any Lien on any of such Borrower’s properties. 
  
 (c) No authorization or approval or other action by, and no notice to or filing with, any governmental
authority or regulatory body or other Person is required for the due execution, delivery or performance by each Borrower of any Loan Document to which such Borrower is a party. Neither Borrower is an “investment company” within the meaning
of the Investment Company Act of 1940, as amended. 
  
 (d) Each Loan Document to which each Borrower is a party constitutes the legal, valid and binding obligation of such Borrower, enforceable against such Borrower in accordance with its terms.

 30 

 
and cash flows for the three months then ended, to year-end audit adjustments, the Consolidated financial condition of Ambac Financial, Ambac Assurance and
their Subsidiaries as at the respective dates thereof and the results of their operations for the respective periods then ended. Since December 31, 2004, there has been no Material Adverse Change. 
  
 (f) There is no pending or, to the knowledge of each
Borrower, threatened litigation, action, proceedings, investigation or labor controversy affecting such Borrower or any Material Subsidiary or any of its respective properties, businesses, assets or revenues which may reasonably be expected to have
a Material Adverse Effect or which purports to affect the legality, validity or enforceability of any Loan Document. 
  
 (g) Each of the Borrowers and its Material Subsidiaries has filed all tax returns and reports required by law to have been filed by it and
has paid all taxes and governmental charges thereby shown to be owing, except any such taxes or charges which are being diligently contested in good faith by appropriate proceedings and for which adequate reserves in accordance with GAAP (or
statutory accounting principles, as appropriate) shall have been set aside on its books and except where the failure to file said returns or reports or to pay such taxes or charges could not reasonably be expected to have a Material Adverse Effect.

has occurred with respect to any Pension Plan sufficient to give rise to a Lien under section 302(f) of ERISA. No condition exists or event or transaction has occurred with respect to any Pension Plan which might result in the incurrence by either
Borrower or any member of the Controlled Group of any material liability, fine or penalty other than a non-defaulted obligation to make a contribution under Section 302 of ERISA. Except as disclosed in Schedule 4.01(h), neither Borrower nor any

collection of the Advances and the Notes), the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining
from acting) upon the instructions of the Required Lenders or all the Lenders if applicable, and such instructions shall be binding upon all Lenders and all holders of the Advances and the Notes; provided, however, that the

Acceptance entered into by the Lender that is the payee of such Note, as assignor, and an Eligible Assignee, as assignee, as provided in Section 8.07; (ii) the Administrative Agent may consult with legal counsel (including counsel for the

furnished pursuant hereto; and (vi) the Administrative Agent shall not incur any liability under or in respect of this Agreement by acting upon any notice, consent, certificate or other instrument or writing (which may be by telecopier) believed by

 SECTION 7.03 Administrative Agent and Affiliates. With respect to its Commitment, the Advances made by it and the Note or Notes issued to it, the Administrative Agent shall have the same rights and powers under this Agreement as any
other Lender and may exercise the same as though it were not the Administrative Agent; and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include the Administrative Agent in its

not acting as the Administrative Agent and without any duty to account therefor to the Lenders. 
  
 SECTION 7.04 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any
Lender or any of the Persons identified on the cover page hereof as “Co-Syndication Agents”, “Sole Lead Arranger” or “Sole Book Runner”, and based on the financial statements referred to in Section 4.01 and such other
documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon any such Person and based on such
documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement. 
  
 SECTION 7.05 Indemnification. The Lenders agree to indemnify the Administrative Agent (to the extent not reimbursed
by the Borrowers), ratably according to the respective principal amounts of the Advances and Notes then held by each of them (or if no Notes are at the time outstanding) ratably according to the respective amounts of their Commitments), from and
against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Administrative Agent
in any way arising out of this Agreement or any action taken or omitted by the Administrative Agent under this Agreement (collectively, the “Indemnified Costs”), provided that no Lender shall be liable for any portion of the
Indemnified Costs resulting from the Administrative Agent’s gross negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon demand for its ratable share of any
out-of-pocket fees and expenses (including counsel fees and expenses) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations,
legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, to the extent that the Administrative Agent is not reimbursed for such fees and expenses by the Borrowers. In the case of any
investigation, litigation or proceeding giving rise to any Indemnified Costs, this Section 7.05 applies whether any such investigation, litigation or proceeding is brought by the Administrative Agent, any Lender or a third party. 
  
 SECTION 7.06 Successor. The Administrative Agent may resign at any
time by giving written notice thereof to the Lenders and the Borrowers and may be removed at any time with or without cause by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right to appoint a
successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Required Lenders, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s giving of notice of
resignation or the Required Lenders’ removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor 

  

 40 

 
Administrative Agent, which shall be a commercial bank organized under the laws of the United States of America or of any State thereof and having a combined
capital and surplus of at least $500,000,000. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the
rights, powers, discretion, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement. After any retiring Administrative Agent’s
resignation or removal hereunder as Administrative Agent, the provisions of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. 
  
 ARTICLE VIII 
  
 MISCELLANEOUS 
  
 SECTION 8.01 Amendments, Etc. No amendment or waiver of any provision of this Agreement or the Notes, nor consent to any departure by either
Borrower therefrom, shall in any event be effective unless the same shall be in writing and signed by the Required Lenders, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which
given; provided, however, that no amendment, waiver or consent shall, unless in writing and signed by all the Lenders, do any of the following: (a) waive any of the conditions specified in Section 3.01, (b) except as provided in
Section 2.16, increase or extend the Commitments of the Lenders or subject the Lenders to any additional obligations, (c) reduce the principal of, or interest on, the Advances or the Notes or any fees payable under Section 2.03, or any other amounts
payable hereunder, (d) postpone any date fixed for any payment of principal of, or interest on, the Advances or the Notes or any fees or other amounts payable hereunder, (e) change the percentage of the Commitments or of the aggregate unpaid
principal amount of the Advances or the Notes, or the number of Lenders, that shall be required for the Lenders or any of them to take any action hereunder or (f) amend this Section 8.01 or the definition of “Required Lenders”; and
provided, further, that no amendment, waiver or consent shall, unless in writing and signed by the Administrative Agent in addition to the Lenders required above to take such action, affect the rights or duties of the Administrative
Agent under this Agreement or any Note. 
  
 SECTION 8.02
Notices, Etc. (a) All notices and other communications provided for hereunder shall be in writing (including telecopier) and mailed, telecopied or delivered, if to either Borrower, at its address at One State Street Plaza, New York, New York,
10004, Attention: Treasurer (with copy to General Counsel at same address); if to any Lender, at its Domestic Lending Office specified opposite its name on Schedule III hereto or at its Domestic Lending Office specified in the Assignment and
Acceptance pursuant to which it became a Lender, as the case may be; and if to the Administrative Agent, at its address at Citibank, N.A., 2 Penns Way, Suite 110, New Castle, Delaware 19720, Attention: Mr. Nick Rozell (fax: 212-994-0961); or, as to
the Borrowers or the Administrative Agent, at such other address as shall be designated by such party in a written notice to the other parties and, as to each other party, at such other address as shall be designated by such party in a written

 41 

 
mailed or telecopied, be effective when deposited in the mails or telecopied, respectively, except that notices and communications to the Administrative
Agent pursuant to Article II, III or VII shall not be effective until received by the Administrative Agent. Delivery by telecopier of an executed counterpart of any amendment or waiver of any provision of this Agreement or the Notes or of any
Exhibit hereto to be executed and delivered hereunder shall be effective as delivery of a manually executed counterpart thereof. 
  
 (b) Each Borrower hereby agrees that it will provide to the Administrative Agent all information, documents and other materials that it is
obligated to furnish to the Administrative Agent pursuant to this Agreement, including, without limitation, all notices, requests, financial statements, financial and other reports, certificates and other information materials, but excluding any
such communication that (i) relates to the payment of any principal or other amount due under this Agreement prior to the scheduled date therefor, (ii) provides notice of any Default under this Agreement or (iii) is required to be delivered to
satisfy any condition precedent to the occurrence of the Closing Date (all such non-excluded communications being referred to herein collectively as “Communications”), by transmitting the Communications in an electronic/soft medium
in a format acceptable to the Administrative Agent to oploanswebadmin@citigroup.com. In addition, each Borrower agrees to continue to provide the Communications to the Administrative Agent in the manner specified in this Agreement but only to the
extent requested by the Administrative Agent. 
  
 (c) Each Borrower further agrees that the Administrative Agent may make the Communications available to the Lenders by posting the Communications on Intralinks or a substantially similar electronic transmission system (the
“Platform”). THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE”. THE AGENT PARTIES (AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE COMMUNICATIONS, OR THE ADEQUACY OF THE PLATFORM AND
EXPRESSLY DISCLAIM LIABILITY FOR ERRORS OR OMISSIONS IN THE COMMUNICATIONS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT LIMITATION, ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF
THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY THE AGENT PARTIES IN CONNECTION WITH THE COMMUNICATIONS OR THE PLATFORM. IN NO EVENT SHALL THE ADMINISTRATIVE AGENT OR ANY OF ITS AFFILIATES OR ANY OF THEIR RESPECTIVE
OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ADVISORS OR REPRESENTATIVES (COLLECTIVELY, THE “AGENT PARTIES”) HAVE ANY LIABILITY TO EITHER BORROWER, ANY LENDER OR ANY OTHER PERSON OR ENTITY FOR DAMAGES OF ANY KIND, INCLUDING, WITHOUT
LIMITATION, DIRECT OR INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOSSES OR EXPENSES (WHETHER IN TORT, CONTRACT OR OTHERWISE) ARISING OUT OF SUCH BORROWER’S OR THE ADMINISTRATIVE AGENT’S TRANSMISSION OF COMMUNICATIONS THROUGH
THE INTERNET, EXCEPT TO THE EXTENT THE LIABILITY OF ANY AGENT PARTY IS FOUND IN A FINAL NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED PRIMARILY FROM SUCH AGENT PARTY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

  

 42 

 (d) The Administrative Agent agrees that the receipt of the Communications by the
Administrative Agent at its e-mail address set forth above shall constitute effective delivery of the Communications to the Administrative Agent for purposes of this Agreement. Each Lender agrees that notice to it (as provided in the next sentence)
specifying that the Communications have been posted to the Platform shall constitute effective delivery of the Communications to such Lender for purposes of the Loan Documents. Each Lender agrees (i) to provide to the Administrative Agent in writing
(including by electronic communication), promptly after the date of this Agreement, an e-mail address to which the foregoing notice may be sent by electronic transmission and (ii) that the foregoing notice may be sent to such e-mail address.

  
 (e) Nothing herein shall prejudice the right
of either Borrower, the Administrative Agent or any Lender to give any notice or other communication pursuant to this Agreement in any other manner specified in this Agreement. 
  
 SECTION 8.03 No Waiver; Remedies. No failure on the part of any Lender or the Administrative Agent to exercise, and
no delay in exercising, any right hereunder or under any Note shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The
remedies herein provided are cumulative and not exclusive of any remedies provided by law. 
  
 SECTION 8.04 Costs and Expenses. (a) The Borrowers jointly and severally agree to pay in Dollars on demand all out-of-pocket costs and expenses of the Administrative Agent in connection with the preparation,
execution, delivery, administration, modification and amendment of this Agreement, the Notes and the other documents to be delivered hereunder, including the reasonable fees and expenses of counsel for the Administrative Agent with respect thereto
and with respect to advising the Administrative Agent as to its rights and responsibilities under this Agreement. The Borrowers further jointly and severally agree to pay in Dollars on demand all out-of-pocket costs and expenses of the
Administrative Agent and the Lenders, if any, in connection with the enforcement of this Agreement, the Notes and the other documents to be delivered hereunder, limited, in the case of counsel fees and expenses, to the reasonable fees and expenses
of one common counsel for the Administrative Agent and the Lenders. 
  
 (b) The Borrowers jointly and severally agree to indemnify and hold harmless the Administrative Agent and each Lender and each of their Affiliates and their officers, directors, employees, agents and advisors (each,
an “Indemnified Party”) from and against any and all claims, damages, losses, liabilities and expenses (including, without limitation, reasonable fees and expenses of counsel) that may be incurred by or asserted or awarded against
any Indemnified Party, in each case arising out of or relating to the Notes, this Agreement, the transactions contemplated hereby or the actual or proposed use of the proceeds of the Advances, whether or not such investigation, litigation or
proceeding is brought by a Borrower, any of its shareholders or creditors, an Indemnified Party or any other Person, or an Indemnified Party is otherwise, a party thereto, except with respect to any Indemnified Party to the extent such claim,
damage, loss, liability or expense results from such Indemnified Party’s gross negligence or willful misconduct as determined in a final non-appealable judgment by a court of competent 

  

 43 

 
jurisdiction. In no event shall any Indemnified Party have any liability for any special, indirect, consequential or punitive damages in connection with any
matter relating hereto. 
  
 (c) If any payment of
principal of, or Conversion of, any Eurocurrency Rate Advance is made by either Borrower to or for the account of a Lender other than on the last day of the Interest Period for such Advance, as a result of a payment or Conversion pursuant to Section
2.07(c), 2.09 or 2.11, prepayment, acceleration of the maturity of the Advances or the Notes pursuant to Section 6.01 or for any other reason, or if such Borrower fails to make a prepayment of any Eurocurrency Rate Advance under Section 2.09 in
accordance with a notice of prepayment given under such Section, such Borrower shall, upon written demand by such Lender (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender any
amounts required to compensate such Lender for any additional losses, costs or expenses that it may reasonably incur as a result of such payment or Conversion or such failure to prepay, including any loss (excluding loss of anticipated profits),
cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Advance. 
  
 (d) Without prejudice to the survival of any other agreement of each Borrower hereunder, the agreements and obligations of each Borrower
contained in Sections 2.10 and 2.13 and this Section 8.04 shall survive the payment in full of principal and interest payable hereunder and under the Notes. 
  
 SECTION 8.05 Right of Set-off. Upon the occurrence and during the continuance of any Default under Section 6.01(f) or any Event of Default and the
making of the request or the granting of the consent specified by Section 6.01 to authorize the Administrative Agent to declare the Advances and Notes due and payable pursuant to the provisions of Section 6.01, or any actual acceleration of the
maturity thereof pursuant to the proviso at the end of Section 6.01, each Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender to or for the credit or the account of either Borrower against any and all of the obligations of such Borrower now or hereafter existing under
this Agreement and the Note held by such Lender, whether or not such Lender shall have made any demand under this Agreement or such Note and although such obligations may be unmatured. Each Lender agrees promptly to notify such Borrower after any
such set-off and application, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Lender under this Section 8.05 are in addition to other rights and remedies
(including other rights of setoff under applicable law or otherwise) which such Lender may have. 
  
 SECTION 8.06 Binding Effect. This Agreement shall become effective when it shall have been executed by the Borrowers and the Administrative Agent
and when the Administrative Agent shall have been notified by each Lender that such Lender has executed it and thereafter shall be binding upon and inure to the benefit of the Borrowers, the Administrative Agent and each Lender and their respective
successors and assigns, except that the Borrowers shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of the Lenders. 
  

 44 

 SECTION 8.07 Assignments and Participations. (a) Each Lender may, if approved by the Borrowers and
the Administrative Agent (which approvals may not be unreasonably withheld or delayed and which approvals of the Borrowers shall not be required if an Event of Default has occurred and is continuing), and, if demanded by the Borrowers in the event
that at any time any Lender shall cease to have the Required Lender Rating, upon at least 5 Business Days’ notice to such Lender and the Administrative Agent, will assign to one or more Persons all or a portion of its rights and obligations
under this Agreement (including, without limitation, all or a portion of its Commitment, the Advances owing to it and the Note held by it); provided, however, that (i) each such assignment shall be of a constant, and not a varying,
percentage of all rights and obligations under this Agreement, (ii) except in the case of an assignment to a Person that, immediately prior to such assignment, was a Lender or an assignment of all of a Lender’s rights and obligations under this
Agreement, the amount of the Commitment of the assigning Lender being assigned pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $10,000,000
or an integral multiple of $1,000,000 in excess thereof, (iii) each such assignment shall be to an Eligible Assignee and (iv) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording
in the Register, an Assignment and Acceptance, together with any Note subject to such assignment and a processing and recordation fee of $3,500. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in
each Assignment and Acceptance, (A) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a
Lender hereunder and (B) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under
this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto). Notwithstanding the
foregoing, each Lender will have the right, upon notice to the Administrative Agent and with the approval of the Borrowers (which approval may not be unreasonably withheld or delayed and which approval shall not be required if an Event of Default
has occurred and is continuing), to assign all or part of its rights and obligations under any Loan Document to any of its Affiliates. 
  
 (b) By executing and delivering an Assignment and Acceptance, the Lender assignor thereunder and the assignee thereunder confirm to and
agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other instrument or document furnished pursuant hereto; (ii)
such assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of either Borrower or the performance or observance by either Borrower of any of its obligations under this Agreement or
any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in Section 4.01 and such other documents and
information as it has deemed appropriate to make its own credit analysis 

  

 45 

 
and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon the Administrative Agent, such
assigning Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee confirms that
it is an Eligible Assignee; (vi) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers and discretion under this Agreement as are delegated to the Administrative Agent
by the terms hereof, together with such powers and discretion as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations that by the terms of this Agreement are
required to be performed by it as a Lender. 
  
 (c) The Administrative Agent shall maintain at its address referred to in Section 8.02 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and
the Commitment of, and principal amount of the Advances owing to, each Lender from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the
Borrowers, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrowers or any Lender
at any reasonable time and from time to time upon reasonable prior notice. 
  
 (d) Upon its receipt of an Assignment and Acceptance executed by an assigning Lender and an assignee representing that it is an Eligible Assignee, together with any Note or Notes subject to such assignment, the
Administrative Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of Exhibit C hereto, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii)
give prompt notice thereof to each Borrower. Within five Business Days after its receipt of such notice, each Borrower, at its own expense, shall execute and deliver to the Administrative Agent in exchange for the surrendered Note a new Note to the
order of such Eligible Assignee in an amount equal to the Commitment assumed by it pursuant to such Assignment and Acceptance and, if the assigning Lender has retained a Commitment hereunder, a new Note to the order of the assigning Lender in an
amount equal to the Commitment retained by it hereunder. Such new Note or Notes shall be in an aggregate principal amount equal to the aggregate principal amount of such surrendered Note or Notes, shall be dated the effective date of such Assignment
and Acceptance and shall otherwise be in substantially the form of Exhibit A hereto. 
  
 (e) Each Lender may sell participations to one or more banks or other entities (other than the Borrowers or any of their Affiliates) in or
to all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment, the Advances owing to it and the Note or Notes held by it); provided, however, that (i) such
Lender’s obligations under this Agreement (including, without limitation, its Commitment to the Borrowers hereunder) shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of
such obligations, (iii) such Lender shall remain the holder of any such Note for all purposes of this Agreement, (iv) the 

  

 46 

 
Borrowers, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s
rights and obligations under this Agreement and (v) no participant under any such participation shall have any right to approve any amendment or waiver of any provision of this Agreement or any Note, or any consent to any departure by either
Borrower therefrom, except to the extent that such amendment, waiver or consent would reduce the principal of, or interest on, the Notes or any fees or other amounts payable hereunder, in each case to the extent subject to such participation, or
postpone any date fixed for any payment of principal of, or interest on, the Notes or any fees or other amounts payable hereunder, in each case to the extent subject to such participation. 
  
 (f) Any Lender may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section 8.07, disclose to the assignee or participant or proposed assignee or participant any information relating to either Borrower furnished to such Lender by or on behalf of
such Borrower; provided that, prior to any such disclosure, the assignee or participant or proposed assignee or participant shall agree to preserve the confidentiality of any Confidential Information relating to such Borrower received by it
from such Lender. 
  
 (g) Notwithstanding any
other provision set forth in this Agreement, any Lender may at any time create a security interest in all or any portion of its rights under this Agreement (including, without limitation, the Advances owing to it and any Note held by it) in favor of
any Federal Reserve Bank in accordance with Regulation A of the Board of Governors of the Federal Reserve System. 
  
 SECTION 8.08 Confidentiality. Neither the Administrative Agent nor any Lender shall disclose any Confidential Information to any other Person
without the consent of the Borrowers, other than (a) to the Administrative Agent’s or such Lender’s Affiliates and their officers, directors, employees, agents and advisors and, as contemplated by Section 8.07(f), to actual or prospective
assignees and participants, and then only on a confidential basis, (b) as required by any law, rule or regulation or judicial process and (c) as requested or required by any state, federal or foreign authority or examiner regulating banks or
banking. 
  
 SECTION 8.09 Governing Law. This Agreement and
the Notes shall be governed by, and construed in accordance with, the law of the State of New York. 
  
 SECTION 8.10 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by telecopier shall
be effective as delivery of a manually executed counterpart of this Agreement. 
  
 SECTION 8.11 WAIVER OF JURY TRIAL. EACH OF THE BORROWERS, THE ADMINISTRATIVE AGENT AND THE LENDERS HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR
COUNTERCLAIM (WHETHER BASED ON 

  

 47 

 
CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY. 
  
 SECTION 8.12 Judgment Currency. This is an international loan
transaction in which the specification of Dollars or an Alternate Currency, as the case may be (the “Specified Currency”), and payment of Dollars in New York City and of an Alternate Currency in the Principal Financial Center for
such Alternate Currency, as the case may be (the “Specified Place”), is of the essence, and the Specified Currency shall be the currency of account in all events relating to Advances denominated in the Specified Currency. The
payment obligations of the Borrowers under this Agreement and the Notes shall not be discharged by an amount paid in another currency or in another place, whether pursuant to a judgment or otherwise, to the extent that the amount so paid on
conversion to the Specified Currency and transfer to the Specified Place under normal banking procedures does not yield the amount of the Specified Currency at the Specified Place due hereunder. If for the purpose of obtaining judgment in any court
it is necessary to convert a sum due hereunder in a Specified Currency into another currency (the “Second Currency”), the rate of exchange which shall be applied shall be that at which in accordance with normal banking procedures
the Administrative Agent could purchase the Specified Currency with the Second Currency on the Business Day next preceding that on which such judgment is rendered. The obligation of each Borrower in respect of any such sum due from it to the
Administrative Agent or any Lender hereunder (an “Entitled Person”) shall, notwithstanding the rate of exchange actually applied in rendering such judgment, be discharged only to the extent that on the Business Day following receipt
by such Entitled Person of any sum adjudged to be due hereunder or under the Notes in the Second Currency such Entitled Person may in accordance with normal banking procedures purchase and transfer to the Specified Place the Specified Currency with
the amount of the Second Currency so adjudged to be due; and each Borrower hereby, as a separate obligation and notwithstanding any such judgment, agrees to indemnify such Entitled Person against, and to pay such Entitled Person on demand in the
Specified Currency, any difference between the sum originally due to such Entitled Person in the Specified Currency and the amount of the Specified Currency so purchased and transferred. 
  
 SECTION 8.13 European Monetary Union. 
  
 (a) Payments by the Administrative Agent Generally. With respect to the payment of any amount
denominated in Euro, the Administrative Agent shall not be liable to any of the Borrowers or any of the Lenders in any way whatsoever for any delay, or the consequences of any delay, in the crediting to any account of any amount required by this
Agreement to be paid by the Administrative Agent if the Administrative Agent shall have taken all relevant steps to achieve, on the date required by this Agreement, the payment of such amount in immediately available, freely transferable, cleared
funds (in Euro) to the account of any Borrower or any Lender in the Principal Financial Center in the Participating Member State which such Borrower or such Lender, as the case may be, shall have specified for such purpose. For the purposes of this
paragraph, “all relevant steps” means all such steps as may be prescribed from time to time by the regulations or operating procedures of such clearing or settlement system as the Administrative Agent may from time to time determine
for the purpose of clearing or settling payments in Euro. 
  

 48 

 (b) Other Consequential Changes. Without prejudice to the respective liabilities
of the Borrowers to the Lenders and the Lenders to the Borrowers under or pursuant to this Agreement, except as expressly provided in this Section, each provision of this Agreement shall be subject to such reasonable changes of construction as the
Administrative Agent may from time to time reasonably specify to be necessary or appropriate to reflect the introduction of or changeover to Euros in Participating Member States. 
  
 SECTION 8.14 Jurisdiction, Etc. Each of the parties hereto hereby irrevocably and unconditionally submits, for itself
and its property, to the nonexclusive jurisdiction of any New York State court or federal court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement or the Notes, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and
determined in any such New York State court or, to the extent permitted by law, in such federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that any party may otherwise have to bring any action or proceeding relating to this Agreement or the Notes in the courts
of any jurisdiction. 
  
 SECTION 8.15 Nature of
Obligations. The obligations of the Borrowers under the Loan Documents are several obligations, and are not joint and several obligations, of the respective Borrowers unless otherwise expressly provided herein. 
  
 SECTION 8.16 USA PATRIOT Act. Each Lender hereby notifies the
Borrowers that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107 56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrowers, which
information includes the names and addresses of the Borrowers and other information that will allow such Lender to identify the Borrowers in accordance with the Act.

 SCHEDULE IV 
 MCR Costs Formulae 
  

	1.	The MCR Cost is an addition to the interest rate to compensate Lenders for the cost of compliance with (a) the requirements of the Bank of England and/or the Financial Services
Authority (or, in either case, any other authority which replaces all or any of its functions) or (b) the requirements of the European Central Bank. 

  

	2.	On the first day of each Interest Period (or as soon as possible thereafter) the Administrative Agent shall calculate, as a percentage rate, a rate (the “Additional Cost
Rate”) for each Lender, in accordance with the paragraphs set out below. The MCR Cost rate will be calculated by the Administrative Agent as a weighted average of the Lenders’ Additional Cost Rates (weighted in proportion to the
percentage participation of each such Lender in the relevant Advance) and will be expressed as a percentage rate per annum. 

  

	3.	The Additional Cost Rate for any Lender lending from an Applicable Lending Office in a Participating Member State will be the percentage notified by that Lender to the
Administrative Agent. This percentage will be certified by that Lender in its notice to the Administrative Agent to be its reasonable determination of the cost (expressed as a percentage of that Lender’s participation in all Loans made from
that Applicable Lending Office) of complying with the minimum reserve requirements of the European Central Bank in respect of Advances made from that Applicable Lending Office. 

  

	4.	The Additional Cost Rate for any Lender lending from an Applicable Lending Office in the United Kingdom will be calculated by the Administrative Agent as follows:

  

	 	(a)	in relation to an Advance denominated in Sterling: 

  

					
	 	  	AB + C(B – D) + E x 0.01	  	 
	 	  	100 – (A + C)	  	per cent. per annum
	 	  	 	  

  

	 	(b)	in relation to an Advance denominated in Euros: 

  

					
	 	  	E x 0.01	  	 
	 	  	300	  	per cent per annum
	 	  	 	  	 

  
 Where: 
  

	 	A	is the percentage of Eligible Liabilities (assuming these to be in excess of any stated minimum) which that Lender is from time to time required to maintain as an interest free cash
ratio deposit with the Bank of England to comply with cash ratio requirements. 

  

	 	B	is the percentage rate of interest (excluding the Applicable Margin and the MCR Cost and, if applicable, the additional amount of interest specified in Section 2.07(c) payable for
the relevant Interest Period on the Advance. 

	 	C	is the percentage (if any) of Eligible Liabilities which that Lender is required from time to time to maintain as interest bearing Special Deposits with the Bank of England.

  

	 	D	is the percentage rate per annum payable by the Bank of England to the Administrative Agent on interest bearing Special Deposits. 

  

	 	E	designed to compensate Lenders for amounts payable under the Fees Rules and is calculated by the Administrative Agent as being the average of the most recent rates of charge
supplied by the Reference Banks to the Agent pursuant to paragraph 7 below and expressed in pounds per £1,000,000; 

  

	5.	For the purposes of this Schedule: 

  

	 	(a)	“Eligible Liabilities” has the meaning given to it from time to time under or pursuant to the Bank of England Act 1998 or (as may be appropriate) by the Bank of
England. 

  

	 	(b)	“Fees Rules” means the rules on periodic fees contained in the FSA Supervision Manual or such other law or regulation as may be in force from time to time in
respect of the payment of fees for the acceptance of deposits. 

  

	 	(c)	“Fee Tariffs” means the fee tariffs specified in the Fees Rules under the activity group A.1 Deposit acceptors (ignoring any minimum fee or zero rated fee required
pursuant to the Fees Rules but taking into account any applicable discount rate). 

  

	 	(d)	“Special Deposits” has the meaning given to it from time to time under or pursuant to the Bank of England Act 1998 or (as may be appropriate) by the Bank of
England. 

  

	 	(e)	“Tariff Base” has the meaning given to it in, and will be calculated in accordance with, the Fees Rules. 

  

	6.	In application of the above formulae, A, B, C and D will be included in the formulae as percentages (i.e. 5 per cent. will be included in the formula as 5 and not as 0.05). A
negative result obtained by subtracting D from B shall be taken as zero. The resulting figures shall be rounded to four decimal places. 

  

	7.	If requested by the Administrative Agent, each Reference Bank shall, as soon as practicable after publication by the Financial Services Authority, supply to the Administrative
Agent, the rate of charge payable by that Reference Bank to the Financial Services Authority pursuant to the Fees Rules in respect of the relevant financial year of the Financial Services Authority (calculated for this purpose by that Reference Bank
as being the average of the Fee Tariffs applicable to that Reference Bank for that financial year) and expressed in pounds per £1,000,000 of the Tariff Base of that Reference Bank. 

	8.	Each Lender shall supply any information required by the Administrative Agent for the purpose of calculating its Additional Cost Rate. In particular, but without limitation, each
Lender shall supply the following information on or prior to the date on which it becomes a Lender: 

  
 (a) the jurisdiction of its Applicable Lending Office; and 
  
 (b) any other information that the Agent may reasonably require for such purpose. 
  
 Each Lender shall promptly notify the Administrative Agent of any change to the information provided by it pursuant to this
paragraph. 
  
 The percentages of each Lender for the purpose of
A and C above and the rates of charge of each Reference Bank for the purpose of E above shall be determined by the Administrative Agent based upon the information supplied to it pursuant to paragraphs 7 and 8 above and on the assumption that, unless
a Lender notifies the Administrative Agent to the contrary, each Lender’s obligations in relation to cash ratio deposits and Special Deposits are the same as those of a typical bank from its jurisdiction of incorporation with an Applicable
Lending Office in the same jurisdiction as its Applicable Lending Office. 
  

	9.	The Administrative Agent shall have no liability to any person if such determination results in an Additional Cost Rate which over or under compensates any Lender and shall be
entitled to assume that the information provided by any Lender or Reference Bank pursuant to paragraphs 3, 7 and 8 above is true and correct in all respects. 

  

	10.	The Administrative Agent shall distribute the additional amounts received as a result of the MCR Cost to the Lenders on the basis of the Additional Cost Rate for each Lender based
on the information provided by each Lender and each Reference Bank pursuant to paragraphs 3, 7 and 8 above. 

  

	11.	Any determination by the Administrative Agent pursuant to this Schedule IV in relation to a formula, the MCR Cost, an Additional Cost Rate or any amount payable to a Lender shall,
in the absence of manifest error, be conclusive and binding on all parties. 

  

	12.	The Agent may from time to time, after consultation with the Borrowers and the Lenders, determine and notify to all parties any amendments which are required to be made to this
Schedule in order to comply with any change in law, regulation or any requirements from time to time imposed by the Bank of England, the Financial Services Authority or the European Central Bank (or, in any case, any other authority which replaces
all or any of its functions) and any such determination shall, in the absence of manifest error, be conclusive and binding on all parties.

 FOR VALUE RECEIVED,
the undersigned, [AMBAC FINANCIAL GROUP, INC./AMBAC ASSURANCE CORPORATION] (the “Borrower”), HEREBY PROMISES TO PAY on the Commitment Termination Date (as defined in the Credit Agreement referred to below) to the order of
                                 (the “Lender”) for the account
of its Applicable Lending Office (as defined in the Credit Agreement referred to below) the aggregate principal amount of the Advances made by the Lender to the Borrower pursuant to the Credit Agreement dated as of
                    , 2005, among the Borrower, the Lender and certain other lenders parties thereto, and Citibank, N.A., as Administrative

 The Borrower promises to pay interest on the unpaid principal

 The date, amount, Type, Currency, interest rate and duration of Interest
Period of each Advance made by the Lender to the Borrowers, and each payment made on account of the principal thereof, shall be recorded by the Lender on its books and, prior to any transfer of this Note, endorsed by the Lender on the schedule
attached hereto or any continuation thereof, provided that the failure of the Lender to make any such recordation (or any error in making any such recordation) or endorsement shall not affect the obligations of the Borrowers to make a payment
when due of any amount owing under the Credit Agreement or hereunder in respect of the Advances made by the Lender. This Promissory Note is one of the Notes referred to in, and is entitled to the benefits of, the Credit Agreement. The Credit
Agreement, among other things, (i) provides for the making of Advances by the Lender to the Borrower from time to time in an aggregate amount not to exceed at any time outstanding the Dollar amount first above mentioned, the indebtedness of the
Borrower resulting from each such Advance being evidenced by this Promissory Note, and (ii) contains provisions for acceleration of the maturity hereof upon the happening of certain stated events and also for prepayments on account of principal
hereof prior to the maturity hereof upon the terms and conditions therein specified.

 Citibank, N.A., as Administrative Agent 
 (as defined below)

  

	Re:	Ambac Financial Group, Inc. 

 $400 Million
Credit Agreement 
  
 Ladies and Gentlemen: 
  
 This opinion is delivered to you pursuant to Section 3.01(c)(vi) of the
Credit Agreement dated as of July 28, 2005 (the “Credit Agreement”), among Ambac Financial Group, Inc., a Delaware corporation (“Ambac Financial”), Ambac Assurance Corporation, a Wisconsin stock insurance
corporation, the Lenders parties thereto and Citibank, N.A., as Administrative Agent for the Lenders (the “Administrative Agent”). Unless otherwise defined herein, terms defined in the Credit Agreement are used herein as therein
defined. 
  
 I am Assistant General Counsel of Ambac Financial and
have acted as counsel to Ambac Financial in connection with the preparation, execution and delivery of the Credit Agreement. In that connection, I have examined: 
  

	 	1.	the Credit Agreement; 

  

	 	2.	the Notes dated the date hereof, executed by Ambac Financial and payable to each of you as Lenders (the “Ambac Financial Notes”); 

  

	 	3.	the Amended and Restated Certificate of Incorporation of Ambac Financial and all amendments thereto (the “Charter”); and 

  

	 	4.	the By-laws of Ambac Financial and all amendments thereto (the “By-laws”). 

  
 I also have examined and am familiar with the originals, or copies certified or otherwise identified to my satisfaction, of
such documents and corporate records of Ambac Financial, certificates of public officials and officers of Ambac Financial and agreements, instruments and other documents, as I have deemed necessary as a basis for the opinions expressed below. As to
questions of fact material to such opinions, I have, when relevant facts were not independently established by me, relied, to the extent I deemed appropriate, upon certificates of Ambac Financial or its officers, or of public officials. In addition,
I have also assumed the genuineness of all signatures, the authenticity of all documents submitted to me as 

  

 E-1 

 
originals and the conformity with originals of all documents submitted to me as copies thereof. I have also assumed the due execution and delivery, pursuant
to due authorization, of the Credit Agreement by each of the Lenders and the Administrative Agent. 
  
 I am qualified to practice law in the State of New York. I do not purport to express any opinion herein as to the laws of any jurisdiction other than the
laws of the State of New York, the General Corporation Law of the State of Delaware and the Federal laws of the United States of America. 
  
 Based upon the foregoing and upon such investigation, as I have deemed necessary, I am of the following opinion: 
  
 (1) Ambac Financial is a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware. Ambac Financial is duly qualified to do business and is in good standing as a foreign corporation in each jurisdiction where the nature of its business requires such
qualification, except where the failure to be so qualified, singly or in the aggregate, would not have a Material Adverse Effect. 
  
 (2) The execution, delivery and performance by Ambac Financial of the Credit Agreement and the Ambac Financial Notes are within Ambac
Financial’s corporate powers, and have been duly authorized by all necessary corporate action on the part of Ambac Financial. 
  
 (3) There is no pending or, to my knowledge, threatened action, suit, investigation, litigation, proceeding or labor controversy affecting
Ambac Financial before any court, governmental agency or arbitrator which (A) purports to affect the legality, validity or enforceability of the Credit Agreement or any of the Ambac Financial Notes or the consummation of the transactions
contemplated thereby or (B) which could be reasonably likely to have a Material Adverse Effect. 
  
 (4) The execution, delivery and performance by Ambac Financial of the Credit Agreement and the Ambac Financial Notes do not (i) violate or
contravene its Charter or By-laws, or any contractual restriction or law applicable to Ambac Financial or any rule or regulation applicable to Ambac Financial or (ii) result in, or require the creation or imposition of, any Lien on any of Ambac
Financial’s properties. 
  
 (5) The
execution, delivery and performance by Ambac Financial of the Credit Agreement and the Ambac Financial Notes do not conflict with or result in a breach of any of the terms or provisions of, or constitute a default under (i) any indenture, loan
agreement, lease, guarantee, mortgage or other agreement or instrument, or (ii) any order, writ, judgment, award, injunction or decree known to me to which Ambac Financial is a party or by which it is bound or to which any of its properties or
assets are subject, except for such conflicts, breaches or defaults, which individually or in the aggregate, would not have any Material Adverse Effect, would not have a material adverse effect on the legality, validity, binding effect or
enforceability of the Credit 

  

 E-2 

 
Agreement or the Ambac Financial Notes, and would not subject the Administrative Agent or any Lender to any liability. 
  
 (6) No authorization, approval or other action by, and no
notice to or filing with, any governmental authority or regulatory body is required for the due execution, delivery and performance by Ambac Financial of the Credit Agreement or any Ambac Financial Note. 
  
 (7) The Credit Agreement and the Ambac Financial Notes have
been duly executed and delivered on behalf of Ambac Financial. 
  
 A copy of this opinion letter may be delivered by each of you to any Eligible Assignee in connection with and at the time of any assignment and delegation by either of you as a Lender to such Eligible Assignee of a portion of your Advances
and Commitment in accordance with the provisions of the Credit Agreement, and such Eligible Assignee may rely on the opinions expressed above with respect to the Credit Agreement as if this opinion letter were addressed and delivered to such
Eligible Assignee on the date hereof.

change of law or fact that may occur after the date of this opinion letter even though such change may affect the legal analysis, a legal conclusion or any other matter set forth in or relating to this opinion letter.

	RE:	Ambac Assurance Corporation 

  
 Ladies and Gentlemen: 
  
 This opinion is delivered to you pursuant to Section 3.01(c)(viii) of the Credit Agreement dated as of July 28, 2005, (the “Credit Agreement”) among Ambac Financial Group, Inc., a Delaware corporation
(“Ambac Financial”), Ambac Assurance Corporation, a Wisconsin stock insurance corporation (“Ambac Assurance”; together with Ambac Financial, the “Borrowers”), the various commercial lending
institutions as are or may become parties thereto (collectively, the “Lenders”), and Citibank, N.A., as Administrative Agent for the Lenders (the “Administrative Agent”). Unless otherwise defined herein, terms to
which meanings are ascribed in the Credit Agreement are used herein with such meanings. 
  
 We have acted as special counsel for Ambac Assurance in connection with the preparation, execution and delivery of the Credit Agreement. 
  
 In that connection, we have examined: 
  

	 	1.	the Credit Agreement; 

  

	 	2.	the Notes dated the date hereof, executed by Ambac Assurance and payable to each of you as Lenders (the “Ambac Assurance Notes”);

	 	5.	the Certificate of Authority issued to Ambac Assurance by the Office of the Commissioner of Insurance for the State of Wisconsin. 

  
 We have examined the originals, or copies certified to our satisfaction, of such other
corporate records of Ambac Assurance, certificates of public officials and of officers of Ambac Assurance and Ambac Financial and agreements, instruments and other documents, as we have deemed 

  

 G-1 

 
necessary as a basis for the opinions expressed below. As to questions of fact material to such opinions, we have, when relevant facts were not independently
established by us, relied, to the extent we deemed appropriate, upon certificates of Ambac Assurance and Ambac Financial or their respective officers, or of public officials. We have assumed the due execution and delivery, pursuant to due
authorization, of the Credit Agreement by the Lenders and the Administrative Agent. We have assumed the due execution and delivery of the Credit Agreement and the Ambac Assurance Notes, the genuineness of all signatures, the authenticity of all
documents submitted to us as originals and the conformity to originals of all documents submitted to us as copies thereof. 
  
 QUALIFICATIONS AND ASSUMPTIONS 
  
 (1) We are qualified to practice law in the State of Wisconsin and the opinions expressed herein relate solely to the laws of the State of Wisconsin and
are limited to the presently existing statutes of the State of Wisconsin and the published decisions of the State of Wisconsin and federal courts. 
  
 (2) We assume that Ambac Financial is a Delaware corporation and wholly owns the outstanding capital stock of Ambac Assurance, which fact has been
certified to us by Ambac Financial. 
  
 (3) The insurance laws of
the State of Wisconsin govern the activities of Ambac Assurance and the agreements, transactions and other activities between Ambac Assurance and its affiliates, including Ambac Financial. The opinions set forth below are limited to the agreements
and other documents specified herein and no opinion is rendered herein regarding any agreements or transactions between Ambac Assurance and its affiliates, including Ambac Financial. 
  
 OPINION 
  
 Based solely upon the foregoing and subject to the qualifications and assumptions stated above, in our opinion: 
  
 (1) Ambac Assurance is a corporation duly organized, validly
existing and in good standing under the laws of the State of Wisconsin. Ambac Assurance is licensed as an insurance company by the Office of the Commissioner of Insurance of the State of Wisconsin. 
  
 (2) The execution, delivery and performance by Ambac
Assurance of the Credit Agreement and the Ambac Assurance Notes: (a) are within Ambac Assurance’s corporate powers and have been duly authorized by all necessary corporate action on the part of Ambac Assurance; and (b) do not violate or
contravene the Charter or Bylaws of Ambac Assurance or any laws or regulations of the State of Wisconsin. 
  
 (3) No authorization, approval or other action by and no notice to or filing with the Office of the Commissioner of Insurance of the State
of Wisconsin or any other Wisconsin governmental authority or regulatory body is required for the due 

  

 G-2 

 
execution, delivery and performance by either Borrower of the Credit Agreement or any Ambac Assurance Note. 
  
 (4) a. The New York governing law clauses of the Credit
Agreement and the Ambac Assurance Notes to which Ambac Assurance is a party are valid under the law of the State of Wisconsin. 
  
 b. Under the law of the State of Wisconsin, the law of the State of New York will be applied to the Loan Documents to which Ambac
Assurance is a party, except to the extent that any term of such documents or any provision of the law of the State of New York applicable to such document violates an important public policy of the State of Wisconsin. We have no reason to believe
that any such term violates an important public policy of the State of Wisconsin. 
  
 (5) Assuming that the Credit Agreement and the Ambac Assurance Notes are legal, valid, binding and enforceable under the law of the State
of New York, the Credit Agreement and the Ambac Assurance Notes constitute the legal, valid and binding obligations of Ambac Assurance, and are enforceable against Ambac Assurance in accordance with their respective terms. 
  
 The opinions set forth above are subject to the following qualifications: 
  
 a. Our opinion in Paragraph 5 is subject to the effect of
any applicable bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or similar law affecting creditors’ rights generally. 
  
 b. Our opinion in Paragraph 5 above is also subject to the
effect of general principles of equity, including (without limitation) concepts of materiality, reasonableness, good faith and fair dealing (regardless of whether considered in proceeding in equity or at law).

 Ambac Financial Group, Inc. and Ambac Assurance Corporation 
  

Ladies and Gentlemen: 
  
 This opinion is furnished to you pursuant to Section 3.01(c)(ix) of the Credit Agreement dated as of July 28, 2005 (the “Credit
Agreement”), among Ambac Financial Group, Inc. and Ambac Assurance Corporation (the “Borrowers”), the Lenders parties thereto, and Citibank, N.A., as Administrative Agent for said Lenders. Terms defined in the Credit
Agreement are used herein as therein defined. 
  
 We have acted as
special New York counsel for the Borrowers in connection with the preparation, execution and delivery of the Credit Agreement. 
  
 In that connection, we have examined: 
  
 (1) The Credit Agreement. 
  
 (2) The documents furnished by each Borrower pursuant to Article III of the Credit Agreement, including the Notes furnished by each
Borrower thereunder on the date hereof (for purposes of this opinion letter, the “Notes”). 
  
 We have also examined the originals, or copies certified to our satisfaction, of such certificates of officers of each Borrower and agreements, instruments and other documents, as we have deemed necessary as a basis
for the opinions expressed below. As to questions of fact material to such opinions, we have, when relevant facts were not independently established by us, relied upon certificates of each Borrower. 
  
 In our examination of the documents, certificates and instruments referred to
above, we have assumed the authenticity of all such documents, certificates and instruments submitted to us as originals, the genuineness of all signatures, the due authority of the parties executing such documents, certificates and instruments, and
the conformity to authentic originals of all such documents, certificates or instruments submitted to us as copies. We have also assumed, without independent investigation, that (a) each Borrower (i) is a corporation duly organized and validly
existing under the laws of the state of its organization and (ii) has full 

  

 H-1 

 
power and authority to enter into and perform its obligations under the Credit Agreement and the Notes, (b) the execution, delivery and performance by each
Borrower of the Credit Agreement and the Notes have been duly authorized by all necessary board, company, member, manager or officer action and do not violate or contravene any law, rule or regulation applicable to either Borrower or any agreement,
instrument or other document binding on or affecting either Borrower or any constituent document of either Borrower, (c) no authorization, approval or other action by, and no notice to or filing with, any governmental authority or regulatory body or
any other Person is required for the due execution, delivery or performance by either Borrower of the Credit Agreement or the Notes, or if any such authorization, approval, action, notice or filing is required therefor, it has been duly obtained or
made and is in full force and effect, (d) the Credit Agreement has been duly executed and delivered, with all necessary power and authority (corporate and otherwise), by each party thereto, other than the Borrowers, and is the legal, valid and
binding obligation of such party, enforceable against such party in accordance with its terms and (e) the Credit Agreement and the Notes have been duly executed and delivered on behalf of each Borrower. 
  
 Based upon the foregoing and upon such investigation as we have deemed
necessary and subject to the qualifications set forth below, we are of the opinion that the Credit Agreement is, and if an Advance were made, each of the Notes evidencing such Advance would be, the legal, valid and binding obligations of each
Borrower, enforceable against each Borrower in accordance with their respective terms. 
  
 Our opinion above is subject to the following qualifications: 
  
 (a) Our opinion is subject to the effect of any applicable bankruptcy, insolvency, reorganization, moratorium or similar law affecting
creditors’ rights generally (including, without limitation, all laws relating to fraudulent transfers). 
  
 (b) Our opinion is also subject to the effect of general principles of equity, including, without limitation, concepts of materiality,
reasonableness, good faith and fair dealing (regardless of whether considered in a proceeding in equity or at law). 
  
 (c) We express no opinion as to the enforceability of the indemnification provisions, or of release or exculpation provisions, set forth
in Section 8.04(b) of the Credit Agreement to the extent enforcement thereof is contrary to public policy regarding the indemnification against or release or exculpation of criminal violations, intentional harm or acts of gross negligence or
recklessness. 
  
 (d) Although the Credit
Agreement provides for obligations of the Borrowers denominated in currencies other than Dollars, we express no opinion as to whether a court would award a judgment in a currency other than Dollars. 
  

 H-2 

 (e) We express no opinion with respect to the enforceability of any indemnity against
loss in converting into a specified currency the proceeds or amount of a court judgment in another currency. 
  
 (f) Our opinion is limited to Generally Applicable Law and we do not express any opinion herein concerning any other law. “Generally
Applicable Law” means the federal law of the United States of America, and the law of the State of New York (including the rules and regulations promulgated thereunder or pursuant thereto), that a New York lawyer exercising customary
professional diligence would reasonably be expected to recognize as being applicable to the Credit Agreement and the Notes. Without limiting the generality of the foregoing definition of Generally Applicable Law, the term “Generally Applicable
Law” does not include any law, rule or regulation (including, without limitation, any insurance law, rule or regulation) that is applicable to either of the Borrowers or to the Credit Agreement or the Notes solely because of the specific assets
or business of any party to the Credit Agreement or the Notes or any of its affiliates. 
  
 A copy of this opinion letter may be delivered by each of you to any Eligible Assignee in connection with and at the time of any assignment and delegation by any of you as a Lender to such Eligible Assignee of a
portion of your Advances and Commitment in accordance with the provisions of the Credit Agreement, and such Eligible Assignee may rely on the opinion expressed above with respect to the Credit Agreement as if this opinion letter were addressed and
delivered to such Eligible Assignee on the date hereof. 
  
 This
opinion letter is rendered to you in connection with the transactions contemplated by the Credit Agreement. This opinion letter may not be relied upon by you or any other Person who is permitted to rely on the opinion expressed herein as specified

second preceding paragraph of any development or circumstance of any kind, including any change of law or fact that may occur after the date of this opinion letter even though such development, circumstance or change may affect the legal analysis, a

parties to such documents are duly organized and validly existing and have the power and authority (corporate or other) to execute, deliver and perform such documents. 
  
 Based upon and subject to the foregoing and subject also to the comments and qualifications set forth below, and having
considered such questions of law as we have deemed necessary as a basis for the opinions expressed below, we are of the opinion that the Credit Agreement constitutes, and each of the Notes, when duly executed and delivered in accordance with the
Credit Agreement will constitute, the legal, valid and binding obligation of each Borrower party thereto, enforceable against each such Borrower in accordance with its terms, except as may be limited by bankruptcy, fraudulent conveyance or transfer,
insolvency, receivership, conservatorship, reorganization, moratorium or other similar laws relating to or affecting the rights of creditors generally, and except as enforceability is subject to the application of general principles of equity
(regardless of whether considered in a proceeding in equity or at law), including, without limitation, (a) the possible unavailability of specific performance, injunctive relief or any other equitable remedy and (b) concepts of materiality,
reasonableness, good faith and fair dealing. 
  
 The foregoing
opinions are subject to the following comments and qualifications: 
  
 (A) The enforceability of provisions in the Credit Agreement to the effect that terms may not be waived or modified except in writing may be limited under certain circumstances. 
  
 (B) The enforceability of Section 8.04(b) of the Credit
Agreement may be limited by (i) laws rendering unenforceable indemnification contrary to Federal or state securities laws and the public policy underlying such laws and (ii) laws limiting the enforceability of provisions exculpating or exempting a
party from, or requiring indemnification of a party for, liability for its own action or inaction, to the extent the action or inaction involves gross negligence, recklessness, willful misconduct or unlawful conduct. 
  
 (C) We express no opinion as to (i) the effect of the laws
of any jurisdiction in which any Lender is located (other than the State of New York) that limit the interest, fees or other charges such Lender may impose, (ii) Section 8.05 of the Credit Agreement or (iii) the first sentence of Section 8.14 of the
Credit Agreement, insofar as such sentence relates to the subject

matter jurisdiction of the United States District Court for the Southern District of New York to adjudicate any controversy related to any of the Loan
Documents. 
  
 (D) We point out with reference to
obligations stated to be payable in a currency other than Dollars that (i) a New York statute provides that a judgment rendered by a court of the State of New York in respect of an obligation denominated in any such other currency would be rendered
in such other currency and would be converted into Dollars at the rate of exchange prevailing on the date of entry of the judgment and (ii) a judgment rendered by a Federal court sitting in the State of New York in respect of an obligation
denominated in any such other currency may be expressed in Dollars, but we express no opinion as to the rate of exchange that would be applied by such Federal court. 
  
 The foregoing opinions are limited to matters involving the Federal laws of the United States and the law of the State of
New York, and we do not express any opinion as to the laws of any other jurisdiction. We express no opinion as to any insurance laws or regulations that are applicable to either Borrower. 
  
 This opinion letter is provided to you by us in our capacity as special New York counsel to the Administrative Agent
pursuant to Section 3.01(c)(xi) of the Credit Agreement and may not be relied upon by any Person for any purpose other than in connection with the transactions contemplated by the Credit Agreement without, in each instance, our prior written
consent. 
  
 Very truly yours,
