AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED UNAUDITED FINANCIAL STATEMENTS

(1)  BASIS OF PRESENTATION

     Ambac Financial Group, Inc., (the "Company") headquartered in New York
City, is a holding company that provides through its affiliates financial
guarantee insurance and financial management services to clients in both the
public and private sectors in the U.S. and abroad. The Company's principal
operating subsidiary, Ambac Assurance Corporation ("Ambac Assurance"), a leading
insurer of municipal and structured finance obligations, has been assigned
triple-A claims-paying ability ratings, the highest ratings available from
Moody's Investors Service, Inc., Standard & Poor's Ratings Group, Fitch
Investors Service, L.P. and Nippon Investors Service, Inc. Through its Financial
Management Services Division, the Company provides investment agreements,
interest rate swaps, investment advisory and cash management services, and
electronic commerce solutions, principally to states, municipalities and their
authorities, school districts, and hospitals and health organizations.

     The Company's consolidated unaudited interim financial statements have
been prepared on the basis of generally accepted accounting principles ("GAAP")
and, in the opinion of management, reflect all adjustments, consisting only of
normal recurring adjustments, necessary for a fair presentation of the Company's
financial condition, results of operations and cash flows for the periods
presented. The preparation of financial statements in conformity with GAAP
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosures of contingent assets and
liabilities at the date of the financial statements and the reported revenues
and expenses during the reporting period. Actual results could differ from those
estimates. The results of operations for the three months and nine months ended
September  30, 1997 may not be indicative of the results that may be expected
for the full year ending December 31, 1997. These consolidated financial
statements and notes should be read in conjunction with the financial statements
and notes included in the audited consolidated financial statements of Ambac
Financial Group, Inc. and its subsidiaries contained in  (i) the Company's
Annual Report on Form 10-K for the year ended December 31, 1996, which was filed
with the Securities and Exchange Commission (the "Commission") on March 31,
1997, (ii) the Company's Quarterly Report on Form 10-Q for the quarterly period

NOTES TO CONSOLIDATED UNAUDITED FINANCIAL STATEMENTS (CONTINUED)

(2)  FUTURE IMPACT OF NEW ACCOUNTING STANDARD

     In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128 ("SFAS 128"), entitled "Earnings Per
Share." SFAS 128 will replace the presentations of primary and fully diluted
earnings per share under current accounting standards with "basic earnings per
share" and "diluted earnings per share," respectively. Basic earnings per share
excludes dilution and is computed by dividing income available to common
shareholders by the weighted average number of common shares outstanding during
the period, whereas primary earnings per share includes the impact of assumed
conversion of common stock equivalents. Diluted earnings per share under SFAS
128 is generally similar to fully diluted earnings per share. For calendar year
enterprises, SFAS 128 must be adopted commencing with year end 1997 financial
statements, and will then apply retroactively to both annual and interim
periods, requiring the restatement of previously presented earnings per share
data. Earlier application of SFAS 128 is not permitted. Based on preliminary
calculations, the Company does not believe that earnings per share computed
under SFAS 128 would be materially different from the earnings per share data
presented herein.


ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF
        FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following paragraphs describe the consolidated results of operations of
Ambac Financial Group, Inc. and its subsidiaries (sometimes collectively
referred to as the "Company") for the three and nine month periods ended
September 30, 1997 and 1996, and its financial condition as of September 30,
1997 and December 31, 1996. These results are presented for the Company's two
business segments: Financial Guarantee Insurance and Financial Management
Services.

RESULTS OF OPERATIONS
THREE MONTHS ENDED SEPTEMBER 30, 1997 VERSUS THREE MONTHS ENDED
SEPTEMBER 30, 1996

     CONSOLIDATED NET INCOME

     The Company's net income for the three months ended September 30, 1997 was
$60.8 million or $0.87 per common share, an increase of 38% from $43.8 million
or $0.63 per common share in the three months ended September 30, 1996. This
increase in net income was attributable to higher operating income in both
business segments.

     FINANCIAL GUARANTEE INSURANCE

     Operating Income. Through its principal operating subsidiary, Ambac

Assurance, the Company insures municipal and structured finance obligations.
Operating income for the three months ended September 30, 1997 was $79.7
million, an increase of 41% from $56.6 million in the three months ended
September 30, 1996. This increase was primarily due to realized gains from sales
of securities for the period, increased premiums earned from the underlying book
of business, and higher net investment income, partially offset by lower
premiums earned from refundings, calls and other accelerations and higher
underwriting and operating expenses.

     Gross Par Written. Ambac Assurance insured $9.3 billion in par value bonds

during the three months ended September 30, 1997, an increase of 12% from $8.3
billion in the three months ended September 30, 1996. Par value written for the
third quarter of 1997 was comprised of $5.9 billion from municipal bond
insurance and $3.4 billion from structured finance insurance, compared to $6.7
billion and $1.6 billion, respectively, in the third quarter of 1996. According
to estimates based on industry sources, the total volume of new issues of
municipal bonds increased 59% from $35.5 billion during the three months ended
September 30, 1996 to $56.3 billion in the three months ended September 30,
1997. During the three months ended September 30, 1997, the insured portion of
the new issue municipal bond market decreased slightly to approximately 51% from
approximately 52% for the three months ended September 30, 1996. (Market size
amounts and insured percentage figures used in this paragraph were determined on
a sale date basis, in conformity with industry practices; all other amounts and
percentage figures in this discussion were determined on a closing date basis.)

September 30, 1997 were $52.4 million, a decrease of 22% from $67.6 million in
the three months ended September 30, 1996. The following table sets forth the
amounts of gross premiums written by type and percent of total:

1997 were $6.5 million, compared to $9.8 million in the third quarter of 1996.
The 34% decrease in ceded premiums written is primarily due to the non-renewal
of the automatic treaty reinsurance for domestic business effective January 1,
1997, partially offset by higher ceded premiums for international business.
Ambac Assurance uses facultative reinsurance agreements to reduce its risk and
manage its insurance portfolio. Ceded premiums written were 12% and 15% of

September 30, 1997 were $45.9 million, a decrease of 21% from the $57.8 million
in the three months ended September 30, 1996. This decrease reflects lower gross
premiums written, offset by lower premiums ceded to reinsurers in the three
months ended September 30, 1997 compared with the corresponding prior period.

     Net Premiums Earned. Net premiums earned during the three months ended
     -------------------                                                   
September 30, 1997 were $35.7 million, an increase of 6% from $33.7 million in
the three months ended September 30, 1996. The increase was primarily the result
of increased premiums earned from the underlying book of business during the
period, partially offset by a decline in premiums earned from refundings, calls
and other accelerations for the three months ended September 30, 1997. Net
premiums earned for the three months ended September 30, 1997 included $3.5
million (which had a net income per common share effect of $0.03) from
refundings, calls and other accelerations of previously insured issues. Net
premiums earned in the three months ended September 30, 1996 included $7.1
million (which had a net income per common share effect of $0.06) from
refundings, calls and other accelerations. Refunding levels vary depending upon
a number of conditions, primarily the relationship between current interest
rates and interest rates on outstanding debt. Excluding the effect of
accelerated earnings from refundings, calls and other accelerations, net
premiums earned for the three months ended September 30, 1997 were $32.2
million, an increase of 21% from $26.7 million in the three months ended
September 30, 1996.

     Net Investment Income. Net investment income for the three months ended
     ---------------------                                                  
September 30, 1997 was $40.1 million, an increase of 9% from $36.9 million in
the three months ended September 30, 1996. The increase was primarily
attributable to the growth of the investment portfolio. Ambac Assurance's
investments in tax-exempt securities amounted to 79% of the total market value
of its portfolio as of September 30, 1997, versus 76% at September 30, 1996. The
average pre-tax yield-to-maturity on the investment portfolio was 6.35% and
6.47% as of September 30, 1997 and 1996, respectively.

     Net Realized Gains (Losses). Net realized gains were $13.9 million for the
     ---------------------------                                               
three months ended September 30, 1997, compared to $5.4 million in net realized
losses for the comparative prior period in 1996.

     Losses and Loss Adjustment Expenses. Losses and loss adjustment expenses
     -----------------------------------                                     
for the three months ended September 30, 1997 were $0.7 million, versus $1.3
million in the three months ended September 30, 1996. Losses and loss adjustment
expenses are generally based upon estimates of the ultimate aggregate losses
inherent in the obligations insured. No salvage was recognized for the three
month periods ended September 30, 1997 and 1996, respectively.

     Underwriting and Operating Expenses. Underwriting and operating expenses
     -----------------------------------                                     
for the third quarter of 1997 were $10.2 million, an increase of 19% from $8.6
million in the third quarter of 1996, primarily as a result of higher gross
underwriting expenses. Underwriting and operating expenses consist of gross
underwriting and operating expenses, less the deferral to future periods of
expenses and reinsurance commissions related to the acquisition of new insurance
contracts, plus the amortization of previously deferred expenses and reinsurance

commissions. During the three month period ended September 30, 1997, gross
underwriting and operating expenses were $14.3 million, an increase of 12% from
$12.8 million in the three months ended September 30, 1996, primarily due to
higher rating agency fees and advertising, partially offset by lower premium
taxes. Underwriting and operating expenses deferred were $7.5 million and $7.3
million for the three months ended September 30, 1997 and 1996, respectively.
The amortization of previously deferred expenses and reinsurance commissions
was $3.4 million and $3.2 million for the three months ended September 30, 1997
and 1996, respectively.


     FINANCIAL MANAGEMENT SERVICES

     Operating Income. Through its Financial Management Services subsidiaries,
     ----------------                                                         
the Company provides investment agreements, interest rate swaps, investment
advisory and cash management services, and electronic commerce solutions,
principally to states, municipalities and their authorities, school districts,
and hospitals and health organizations. Operating income for the three months
ended September 30, 1997 was $4.4 million, up from $1.0 million in the three
months ended September 30, 1996. Revenues for the third quarter of 1997 were
$10.1 million (includes $1.1 million in realized gains), up from $4.0 million in
the third quarter of 1996. The increase was primarily due to the inclusion of
investment advisory and cash management services revenues of Cadre Financial
Services, Inc. ("Cadre"), the assets and name of which the Company acquired on
December 31, 1996, as well as higher revenues on interest rate swaps and
investment agreements. Expenses for the third quarter of 1997 were $5.7 million,
up from $3.1 million in the third quarter of 1996. These increased expenses
resulted primarily from the consolidation of Cadre and the Company's electronic
commerce solutions affiliate, Ambac Connect, Inc., into the Financial Management
Services segment.

the three months ended September 30, 1997 was $5.4 million, up 4% from $5.2
million for the three months ended September 30, 1996, primarily due to lower
net payments received under an interest rate swap related to the Company's
debentures. Other income (deductions), net, includes investment income and
operating expenses of the holding company. Other income (deductions), net, was
$1.0 million for the three months ended September 30, 1997, down from $2.4
million in the comparative prior period.

     Income Taxes. Income taxes for the three months ended September 30, 1997

were at an effective rate of 23.7%, versus 19.9% in the three months ended
September 30, 1996. This increase was primarily due to realized gains in the
three months ended September 30, 1997.

CONDITION AND RESULTS OF OPERATIONS (CONTINUED)


     SUPPLEMENTAL ANALYTICAL FINANCIAL DATA

     Management, equity analysts and investors consider the following four
measures important in analyzing the financial results, and measuring the
intrinsic value of the Company: core earnings; operating earnings; adjusted
gross premiums written; and adjusted book value. However, none of these measures
are promulgated in accordance with GAAP and should not be considered as
substitutes for net income, gross premiums written and book value. The
definitions of core earnings, operating earnings, adjusted gross premiums
written and adjusted book value described below may differ from the definitions
used by other public holding companies of financial guarantee insurers.

     Core Earnings. Core earnings for the three months ended September 30, 1997
     -------------                                                             
were $49.5 million , an increase of 14% from $43.3 million for the three months
ended September 30, 1996. The increase in core earnings was primarily the result
of continued growth in net premiums earned from the underlying book of business
and higher net investment income from insurance operations, as well as higher
operating income from the Financial Management Services segment. The Company
defines core earnings as consolidated net income, less the effect of net
realized gains and losses, net insurance premiums earned from refundings and
calls and certain non-recurring items.

     Operating Earnings. Operating earnings for the third quarter of 1997 were
     ------------------                                                       
$51.5 million, an increase of 9% from $47.3 million in the third quarter of
1996. The Company defines operating earnings as consolidated net income, less
the effect of net realized gains and losses and certain non-recurring items.

          The following table reconciles net income computed in accordance with
GAAP to operating earnings and core earnings for the three months ended
September 30, 1997 and 1996:

written in the period. While most premiums are collected up-front at policy
issuance, a growing portion of premiums are collected on an installment basis.

9% to $34.21 at September 30, 1997 compared to $31.25 at December 31, 1996.  The
Company derives ABV by beginning with stockholders' equity (book value) and
adding or subtracting the after-tax value of: the net unearned premium reserve;
deferred acquisition costs; the present value of estimated net future
installment premiums; and the unrealized gain or loss on investment agreement
liabilities. These adjustments will not be realized until future periods and may
differ materially from the amounts used in determining ABV.

RESULTS OF OPERATIONS
NINE MONTHS ENDED SEPTEMBER 30, 1997 VERSUS NINE MONTHS ENDED SEPTEMBER 30, 1996

     CONSOLIDATED NET INCOME

     The Company's net income for the nine months ended September 30, 1997 was
$164.1 million or $2.35 per common share, a decrease of 27% from $224.3 million
or $3.21 per common share in the nine months ended September 30, 1996. The
decrease in net income from the prior period was primarily the result of a net
realized gain of $155.6 million (which had a net income per common share effect
of $1.44) from the Company's sale of its former affiliate, HCIA Inc. Excluding
the effect of this one-time gain, net income increased 33% over the nine months
ended September 30, 1996. This increase in net income was attributable to higher
operating income in the insurance segment, partially offset by lower operating
income in the Financial Management Services segment.


     FINANCIAL GUARANTEE INSURANCE

     Operating Income. Operating income for the nine months ended September 30,
     ----------------                                                          
1997 was $218.3 million, an increase of 39% from $157.0 million in the nine
months ended September 30, 1996 This increase was primarily due to realized
gains from sales of securities for the period, increased premiums earned from
the underlying book of business and higher net investment income, partially
offset by lower premiums earned from refundings, calls, and other accelerations.

     Gross Par Written. Ambac Assurance insured $27.8 billion in par value bonds
     -----------------                                                          
during the nine months ended  September 30, 1997, an increase of 17% from $23.8
billion in the nine months ended September 30, 1996. Par value written for the
first nine months of 1997 was comprised of $18.4 billion from municipal bond
insurance and $9.4 billion from structured finance insurance, compared to $18.4
billion and $5.4 billion, respectively, in the first nine months of 1996.
According to estimates based on industry sources, the total volume of new issues
of municipal bonds increased 18% from $126.8 billion during the nine months
ended September 30, 1996 to $149.9 billion in the nine months ended September
30, 1997. During the nine months ended September 30, 1997, the insured portion
of the new issue municipal bond market increased to approximately 52% from
approximately 49% for the nine months ended September 30, 1996, reflecting
increased demand for insured bonds.  (Market size amounts and insured percentage
figures used in this paragraph were determined on a sale date basis, in
conformity with industry practices; all other amounts and percentage figures in
this discussion were determined on a closing date basis.)

1997 were $19.1 million, compared to $29.3 million in the first nine months of
1996. The 35% decrease in ceded premiums written is primarily due to the non-
renewal in 1997 of the automatic treaty reinsurance for domestic business,
partially offset by higher ceded premiums for international business. Ambac
Assurance uses facultative reinsurance agreements to reduce its risk and manage
its insurance portfolio. Ceded premiums written were 11% and 17% of gross
premiums written for the nine month periods ended September 30, 1997 and 1996,
respectively.

September 30, 1997 were $158.8 million, an increase of 8% from the $146.8

period.

September 30, 1997 were $109.1 million, an increase of 7% from $101.6 million in
the nine months ended September 30, 1996. The increase was primarily the result
of increased premiums earned from the underlying book of business during the
nine months ended September 30, 1997, partially offset by lower premiums earned
from refundings, calls and other accelerations during the period. Net premiums
earned for the nine months ended September 30, 1997 included $16.9 million
(which had a net income per common share effect of $0.14) from refundings, calls

other accelerations of previously insured issues. Net premiums earned in the
nine months ended September 30, 1996 included $25.2 million (which had a net
income per common share effect of $0.20) from refundings, calls and other
accelerations. Excluding the effect of accelerated earnings from refundings,
calls and other accelerations, net premiums earned for the nine months ended
September 30, 1997 were $92.2 million, an increase of 21% from $76.4 million in
the nine months ended September 30, 1996.

     Net Investment Income. Net investment income for the nine months ended
     ---------------------                                                 
September 30, 1997 was $117.8 million, an increase of 10% from $107.2 million in
the nine months ended September 30, 1996. The increase was primarily
attributable to the growth of the investment portfolio. Ambac Assurance's
investments in tax-exempt securities amounted to 79% of the total market value
of its portfolio as of September 30, 1997, versus 76% at September 30, 1996. The
average pre-tax yield-to-maturity on the investment portfolio was 6.35% and
6.47% as of September 30, 1997 and 1996, respectively.

     Net Realized Gains (Losses). Net realized gains were $18.2 million for the
     ---------------------------                                               
nine months ended September 30, 1997, compared to $25.1 million in net realized
losses for the comparative prior period in 1996. The net realized losses in the
nine months ended September 30, 1996 partially offset the net realized gain on
the sale of HCIA Inc.

     Losses and Loss Adjustment Expenses. Losses and loss adjustment expenses
     -----------------------------------                                     
for the nine months ended September 30, 1997 were $2.1 million, versus $3.8
million in the nine months ended September 30, 1996. Losses and loss adjustment
expenses are generally based upon estimates of the ultimate aggregate losses
inherent in the obligations insured. Losses and loss adjustment expenses,
exclusive of salvage recognized, were $2.2 million and $3.9 million for the nine
months ended September 30, 1997 and 1996, respectively. Salvage recognized
amounted to $0.1 million for both nine month periods ended September 30, 1997
and 1996.

     Underwriting and Operating Expenses. Underwriting and operating expenses
     -----------------------------------                                     
for the first nine months of 1997 were $29.0 million, an increase of 5% from
$27.7 million in the first nine months of 1996, primarily due to higher rating
agency fees and expenses relating to Ambac Insurance UK Limited (which began
operations during the first quarter of 1997), partially offset by lower ceding
commission expenses in the nine months ended September 30, 1997. During the nine
month period ended September 30, 1997, gross underwriting and operating expenses
were $42.3 million, an increase of 4% from $40.6 million in the nine months
ended September 30, 1996. Underwriting and operating expenses deferred were
$23.4 million and $22.9 million for the nine months ended September 30, 1997 and
1996, respectively. Reinsurance commissions which relate to the current period
were none and $0.6 million for the nine months ended September 30, 1997 and
1996, respectively. The amortization of previously deferred expenses and
reinsurance commissions was $10.1 million and $9.5 million for the three months
ended September 30, 1997 and 1996, respectively.

net income per common share effect of $0.03) in the current period for the
consolidation of the Company's Westport,

Connecticut office into the Company's corporate headquarters in New York City.
Revenues for the first nine months of 1997 were $23.6 million (includes $1.1
million in net realized gains), up from $16.1 million in the first nine months
of 1996. The increase was primarily due to the inclusion of revenues of Cadre,
partially offset by lower revenues on interest rate swaps. Expenses for the
first nine months of 1997, excluding the restructuring charge, were $16.7
million, compared to $7.5 million in the first nine months of 1996. These
increased expenses resulted primarily from the consolidation of Cadre and Ambac
Connect into the Financial Management Services segment.

the nine months ended September 30, 1997 was $15.9 million, up slightly from
$15.7 million for the nine months ended September 30, 1996. Other income
(deductions), net, includes investment income and operating expenses of the
holding company. Other income (deductions), net, increased slightly from $3.3
million for the nine months ended September 30, 1996 to $3.4 million for the
nine months ended September 30, 1997.

     Income Taxes. Income taxes for the nine months ended September 30, 1997

were at an effective rate of 21.8%, compared to 27.5% in the nine months ended
September 30, 1996. The higher effective tax rate in the nine months ended
September 30, 1996 reflected the realized gain from the sale of HCIA.


     SUPPLEMENTAL ANALYTICAL FINANCIAL DATA

     Management, equity analysts and investors consider the following four
measures important in analyzing the financial results, and measuring the
intrinsic value of the Company: core earnings; operating earnings; adjusted
gross premiums written; and adjusted book value. However, none of these measures
are promulgated in accordance with GAAP and should not be considered as
substitutes for net income, gross premiums written and book value. The
definitions of core earnings, operating earnings, adjusted gross premiums
written and adjusted book value described below may differ from the definitions
used by other public holding companies of financial guarantee insurers.

     Core Earnings. Core earnings for the nine months ended September 30, 1997
     -------------                                                            
were $144.0 million , an increase of 15% from $125.7 million for the nine months
ended September 30, 1996. The increase in core earnings was primarily the result
of continued growth in net premiums earned from the underlying book of business
and higher net investment income from insurance operations, partially offset by
lower operating income from the Financial Management Services segment. The
Company defines core earnings as consolidated net income, less the effect of net
realized gains and losses, net insurance premiums earned from refundings and
calls and certain non-recurring items.

     Operating Earnings. Operating earnings for the nine months ended September
     ------------------                                                        
30, 1997 were $153.6 million, an increase of 10% from $140.0 million in the nine
months ended September 30, 1996. The Company defines operating earnings as
consolidated net income, less the effect of net realized gains and losses and
certain non-recurring items.

     The weighted average number of shares outstanding during the nine month

respectively .

     Adjusted Gross Premiums Written. Adjusted gross premiums written were
     -------------------------------                                      
$216.7 million in the first nine months of 1997, an increase of 5% from $205.8
million in the first nine months of 1996. The Company defines adjusted gross
premiums written as up-front premiums written plus the present value of
estimated future installment premiums written in the period. While most premiums
are collected up-front at policy issuance, a growing portion of premiums are
collected on an installment basis. The net present value of estimated future
installment premiums written in the nine months ended September 30, 1997 was
$65.5 million, an increase of 41% from $46.3 million in the nine months ended
September 30, 1996. The aggregate net present value of estimated future
installment premiums was $187.5 million and $157.7 million as of September 30,
1997 and December 31, 1996, respectively.

September 30, 1997 compared to $31.25 at December 31, 1996. The Company derives
ABV by beginning with stockholders' equity (book value) and adding or
subtracting the after-tax value of: the net unearned premium reserve; deferred
acquisition costs; the present value of estimated net future installment
premiums; and the unrealized gain or loss on investment agreement liabilities.
These adjustments will not be realized until future periods and may differ
materially from the amounts used in determining ABV.

     LIQUIDITY AND CAPITAL RESOURCES

     Liquidity for the Holding Company. The Company's liquidity, both on a
     ----------------------------------                                   
short-term basis (for the next twelve months) and a long-term basis (beyond the
next twelve months), is largely dependent upon Ambac Assurance's ability to pay
dividends or make payments to the Company and external financings.

     Pursuant to Wisconsin insurance laws, Ambac Assurance may declare
dividends, provided that, after giving effect to the distribution, it would not
violate certain statutory equity, solvency and asset tests. During the nine
months ended September 30, 1997, Ambac Assurance paid dividends of $33.0 million
on its common stock to the Company.

     The Company's principal uses of liquidity are for the payment of its
operating expenses, interest on its debt, dividends on its shares of Common
Stock and capital investments in its subsidiaries. Given the amount of dividends
that the Company expects to receive from Ambac Assurance during 1997 and the
income it expects to receive from its investment portfolio, the Company believes
it will have sufficient liquidity to satisfy its liquidity needs over the next
twelve months, including the payment of dividends on the Common Stock in
accordance with its current dividend policy. Beyond the next twelve months,
Ambac Assurance's ability to declare and pay dividends to the Company may be
influenced by a variety of factors, including adverse market changes, insurance
regulatory changes and changes in general economic conditions. Consequently,
although the Company believes that it will continue to have sufficient liquidity
to meet its debt service and other obligations over the long term, no assurance
can be given that Ambac Assurance will be permitted to dividend amounts
sufficient to pay all of the Company's operating expenses, debt service
obligations and cash dividends on its Common Stock.

     Liquidity for Insurance Operations.  Ambac Assurance's principal uses of
     -----------------------------------                                     
liquidity are for  the payment of operating expenses, reinsurance premiums,
income taxes and dividends to the Company. The Company believes that Ambac
Assurance's operating liquidity needs can be funded exclusively from its
operating cash flow. The principal sources of Ambac Assurance's liquidity are
gross premiums written, scheduled investment maturities and net investment
income. The majority of premiums for Ambac Assurance's Financial Guarantee
Insurance policies are payable in full at the outset of the term of the policy,
even though premiums are earned over the life of such policies for financial
accounting purposes.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

     Liquidity for Financial Management Services Operations. The principal uses
     -------------------------------------------------------                   
of liquidity by the Company's Financial Management Services subsidiaries are the
payment of investment agreement obligations pursuant to defined terms, net
obligations under interest rate swaps, operating expenses and income taxes. The
Company believes that the operating liquidity needs for Financial Management
Services can be funded primarily from its operating cash flow. The principal
sources of this segments liquidity are proceeds from issuance of investment
agreements, net investment income, maturities of securities from its investment
portfolio which are invested with the objective of matching the duration of its
obligations under the investment agreements, net receipts from interest rate
swaps and related hedges and fees for investment management services. The
Company's investment objectives with respect to investment agreements are to
achieve the highest after-tax total return, subject to a minimum average quality
rating of Aa/AA on invested assets, and to maintain cash flow matching of
invested assets to funded liabilities to minimize interest rate and liquidity
exposure. The Company maintains a portion of its Financial Management Services
assets in short-term investments and repurchase agreements in order to meet
unexpected liquidity needs.

     Credit Facilities. The Company and Ambac Assurance have a joint revolving
     ------------------                                                       
credit facility with two major international banks, as co-agents, for $100.0
million, which expires in July 1998. This facility is available for general
corporate purposes, including the payment of claims. As of September 30, 1997
and 1996, no amounts were outstanding under this credit facility.

     Ambac Assurance has an agreement with a group of Aaa/AAA-rated
international banks for a $350.0 million credit facility, expiring in December
2003.  This facility is a seven-year stand-by irrevocable limited recourse line-
of-credit, which will provide liquidity to Ambac Assurance in the event that
claims from municipal obligations exceed specified levels. Repayment of any
amounts drawn under the line will be limited primarily to the amount of any
recoveries of losses related to policy obligations. As of September 30, 1997 and
1996, no amounts were outstanding under this line.

     Stock Repurchase Program. During the nine months ended September 30, 1997,
     -------------------------                                                 
the Company acquired approximately 949,000 shares under its existing stock
repurchase program. Since inception of the Stock Repurchase Program, the Company
has acquired approximately 3,072,000 shares. Under the Stock Repurchase Program
established by the Board of Directors, the Company is authorized to repurchase
up to 6,000,000 shares of the Common Stock.

     Balance Sheet. As of September 30, 1997, the fair value of the Company's
     --------------                                                          
consolidated investment portfolio was $6.13 billion, an increase of 18% from
$5.20 billion at December 31, 1996. This was primarily due to the growth of
operations in both business segments.

     Cash Flows. Net cash provided by operating activities was $258.9 million
     -----------                                                             
and $145.1 million during the nine months ended September 30, 1997 and 1996,
respectively. These cash flows were primarily provided from insurance
operations.

     Net cash provided by financing activities was $533.0 million and $431.4
million during the nine months ended September 30, 1997 and 1996, respectively.
This activity included $554.9 million and $455.2 million, respectively, in
investment agreements issued (net of draws paid).

     The total cash provided by operating and financing activities was $791.9
million and $576.5 million during the nine months ended September 30, 1997 and
1996, respectively. From these totals, $799.5 million and $575.4 million was
used in investing activities during the nine months ended September 30, 1997 and
1996, respectively, principally for purchases of bonds, offset by proceeds from

     Off-Balance Sheet Risk.   In the normal course of business, the Company
     -----------------------                                                
uses interest rate contracts for hedging purposes as part of its overall
interest rate risk management. In addition, one of the subsidiaries in the
Financial Management Services segment is a dealer of interest rate swaps
primarily to states, municipalities and municipal authorities. This subsidiary
manages its interest rate swap business with the goal of being market neutral to
changes in taxable interest rates, while retaining "basis risk," the
relationship between changes in floating tax-exempt and floating taxable
interest rates. In the ordinary course of business, the Company manages a
variety of other risks principally credit, market, liquidity, operational, and
legal. These risks are identified, measured, and monitored through a variety of
control mechanisms, which are in place at different levels throughout the
organization.
 
     Material Commitments. The Company has made no commitments for material
     ---------------------                                                 
capital expenditures within the next twelve months. However, management
continually evaluates opportunities to expand the Company's businesses through
internal development of new products as well as acquisitions. (See "Part II
Other Information, Item 5." for Ambac Assurance's proposed acquisition of
Construction Loan Insurance Corporation.)

PART II - OTHER INFORMATION

     Items 1, 2, 3 and 4 are omitted either because they are inapplicable or
because the answer to such question is negative.

ITEM 5 - OTHER INFORMATION

     On November 12, 1997, Ambac Assurance announced that the Company and the
shareholders of Construction Loan Insurance Corporation ("CLIC") had approved
their previously announced plans to merge. The merger, which Ambac Assurance
expects to close by December 31, 1997, remains subject to certain contingencies
including satisfaction of applicable federal and state regulatory requirements.
Ambac Assurance will pay $106 million in cash for all of the outstanding shares
of stock of CLIC and will also retire $18.4 million of CLIC's debt obligations.
Based on unaudited financial statements as of September 30, 1997, CLIC had a
book value of $160.8 million. Assuming the merger is consummated as anticipated,
the purchase is expected to have a positive effect on the earnings of the
Company in the range of approximately $0.07 to $0.09 per share in 1998,
depending upon several factors, including, interest rates and general economic
conditions. CLIC is a private, for-profit financial guaranty company that,
through its wholly-owned insurance subsidiary, Connie Lee Insurance Company
("Connie Lee"), guarantees bonds primarily issued for college and hospital
infrastructure projects. While Ambac Assurance does not expect Connie Lee to
write new business, it will make sure that Connie Lee bonds retain their triple-
A ratings.

preferences and rights and the qualifications, limitations or restrictions
thereof of the shares of each class as Preferred Stock are as follows:

     (a) The Preferred Stock may be issued from time to time in one or more

  other special rights and qualifications, limitations or restrictions thereof
  as are stated and expressed herein or in the resolution or resolutions
  providing for the issuance of such series, adopted by the Board of Directors

  Directors of the Corporation provides that any series of Preferred Stock shall
  be given voting powers, such series shall not be entitled to vote separately
  as a single class other than as expressly required by law and for the election
  of one or more additional directors of the Corporation in the case of dividend
  arrearages or other specified events and such series of Preferred Stock shall
  not be granted the right to cast in excess of one vote per share of Preferred
  Stock.

     (b) Authority is hereby expressly granted to the Board of Directors,
  subject to the provisions of this Article IV and to the limitations prescribed
  by law, to authorize the issuance of one or more series of Preferred Stock and
  with respect to each such series to fix by resolution or resolutions providing

  the shares of such series and the designations, preferences and relative,
  participating, optional or other special rights and the qualifications,
  limitations or restrictions thereof. The authority of the Board of Directors

     SECTION 4.3.  SERIES A JUNIOR PARTICIPATING PREFERRED STOCK.  Pursuant to
the authority vested in the Board of Directors in accordance with Section 4.2
hereof, the Board of Director has authorized the creation of a series of
Preferred Stock with the designation and amount thereof and the voting powers,
preferences and relative, participating, optional and other special rights of
the shares of such series, and the qualifications, limitations or restrictions
thereof as follows:

     (a) DESIGNATION AND AMOUNT.  The shares of such series shall be designated
  as "SERIES A JUNIOR PARTICIPATING PREFERRED STOCK" and the number of shares
  constituting such series shall be 500,000.

     (b) DIVIDENDS AND DISTRIBUTIONS.

       (i) Subject to the prior and superior rights of the holders of any shares
     of any series of Preferred Stock ranking prior and superior to the shares
     of Series A Junior Participating Preferred Stock with respect to dividends,
     the holders of shares of Series A Junior Participating Preferred Stock
     shall be entitled to receive, when, as and if declared by the Board of
     Directors out of funds legally available for the purpose, quarterly
     dividends payable in cash on the fifteenth day of March, June, September
     and December in each year (each such date being referred to herein as a
     "QUARTERLY DIVIDEND PAYMENT DATE"), commencing on the first Quarterly
     Dividend Payment Date after the first issuance of a share or fraction of a
     share of Series A Junior Participating Preferred Stock, in an amount per
     share (rounded to the nearest cent) equal to the greater of (a) $1.00 or
     (b) subject to the provision for adjustment hereinafter set forth, 100
     times the aggregate per share amount of all cash dividends, and 100 times
     the aggregate per share amount (payable in kind) of all non-cash dividends
     or other distributions other than a dividend payable in shares of Common
     Stock or a subdivision of the outstanding shares of Common Stock (by
     reclassification or otherwise), declared on the Common Stock since the
     immediately preceding Quarterly Dividend Payment Date, or, with respect to
     the first Quarterly Dividend Payment Date, since the first issuance of any
     share or fraction of a share of Series A Junior Participating Preferred
     Stock. In the event the Corporation shall at any time after January 31,
     1996 (the "RIGHTS DECLARATION DATE") (i) declare any dividend on Common
     Stock payable in shares of Common Stock, (ii) subdivide the outstanding
     Common Stock, or (iii) combine the outstanding Common Stock into a smaller
     number of shares, then in each such case the amount to which holders of
     shares of Series A Junior Participating Preferred Stock were entitled
     immediately prior to such event under clause (b) of the preceding sentence
     shall be adjusted by multiplying such amount by a fraction the numerator of
     which is the number of shares of Common Stock outstanding immediately after
     such event and the denominator of which is the number of shares of Common
     Stock that were outstanding immediately prior to such event.

       (ii) The Corporation shall declare a dividend or distribution on the
     Series A Junior Participating Preferred Stock as provided in subparagraph
     (b)(i) above immediately after it declares a dividend or distribution on
     the Common Stock (other than a dividend payable in shares of Common Stock);
     provided that, in the event no dividend or distribution shall have been
     declared on the Common Stock during the period between any Quarterly
     Dividend Payment Date and the next subsequent Quarterly Dividend Payment
     Date, a dividend of $1.00 per share on the Series A Junior Participating
     Preferred Stock shall nevertheless be payable on such subsequent Quarterly
     Dividend Payment Date.

       (iii) Dividends shall begin to accrue and be cumulative on outstanding
     shares of Series A Junior Participating Preferred Stock from the Quarterly
     Dividend Payment Date next preceding the date of issue of such shares of
     Series A Junior Participating Preferred Stock, unless the date of issue of
     such shares is prior to the record date for the first Quarterly Dividend
     Payment Date, in which case dividends on such shares shall begin to accrue
     from the date of issue of such shares, or unless the date of issue is a
     Quarterly Dividend Payment Date or is a date after the 

                                       3
<PAGE>
 
     record date for the determination of holders of shares of Series A Junior
     Participating Preferred Stock entitled to receive a quarterly dividend and
     before such Quarterly Dividend Payment Date, in either of which events such
     dividends shall begin to accrue and be cumulative from such Quarterly
     Dividend Payment Date. Accrued but unpaid dividends shall not bear
     interest. Dividends paid on the shares of Series A Junior Participating
     Preferred Stock in an amount less than the total amount of such dividends
     at the time accrued and payable on such shares shall be allocated pro rata
     on a share-by-share basis among all such shares at the time outstanding.
     The Board of Directors may fix a record date for the determination of
     holders of shares of Series A Junior Participating Preferred Stock entitled
     to receive payment of a dividend or distribution declared thereon, which
     record date shall be no more than 30 days prior to the date fixed for the
     payment thereof.


     (c) VOTING RIGHTS.  The holders of shares of Series A Junior Participating
  Preferred Stock shall have the following voting rights:

       (i) Each share of Series A Junior Participating Preferred Stock shall
     entitle the holder thereof to one vote on all matters submitted to a vote
     of the stockholders of the Corporation.

       (ii) Except as otherwise provided herein or by law, the holders of shares
     of Series A Junior Participating Preferred Stock and the holders of shares
     of Common Stock shall vote together as one class on all matters submitted
     to a vote of stockholders of the Corporation.

       (iii) (A) If at any time dividends on any Series A Junior Participating
     Preferred Stock shall be in arrears in an amount equal to six (6) quarterly
     dividends thereon, the occurrence of such contingency shall mark the
     beginning of a period (herein called a "DEFAULT PERIOD") which shall extend
     until such time when all accrued and unpaid dividends for all previous
     quarterly dividend periods and for the current quarterly dividend period on
     all shares of Series A Junior Participating Preferred Stock then
     outstanding shall have been declared and paid or set apart for payment.
     During each default period, all holders of Preferred Stock (including
     holders of the Series A Junior Participating Preferred Stock) with
     dividends in arrears in an amount equal to six (6) quarterly dividends
     thereon, voting as a class, irrespective of series, shall have the right to
     elect two (2) Directors.

          (B) During any default period, such voting right of the holders of
       Series A Junior Participating Preferred Stock may be exercised initially
       at a special meeting called pursuant to subparagraph (C) of this
       subsection (c)(iii) or at any annual meeting of stockholders, and
       thereafter at annual meetings of stockholders, provided that such voting
       right shall not be exercised unless the holders of ten percent (10%) in
       number of shares of Preferred Stock outstanding shall be present in
       person or by proxy. The absence of a quorum of the holders of Common
       Stock shall not affect the exercise by the holders of Preferred Stock of
       such voting right. At any meeting at which the holders of Preferred Stock
       shall exercise such voting right initially during an existing default
       period, they shall have the right, voting as a class, to elect Directors
       to fill such vacancies, if any, in the Board of Directors as may then
       exist up to two (2) Directors or, if such right is exercised at an annual
       meeting, to elect two (2) Directors. If the number which may be so
       elected at any special meeting does not amount to the required number,
       the holders of the Preferred Stock shall have the right to make such
       increase in the number of Directors as shall be necessary to permit the
       election by them of the required number. After the holders of the
       Preferred Stock shall have exercised their right to elect Directors in
       any default period and during the continuance of such period, the number
       of Directors shall not be increased or decreased except by vote of the
       holders of Preferred Stock as herein provided or pursuant to the rights
       of any equity securities ranking senior to or pari passu with the Series
       A Junior Participating Preferred Stock.

                                       4
<PAGE>
 
          (C) Unless the holders of Preferred Stock shall, during an existing
       default period, have previously exercised their right to elect Directors,
       the Board of Directors may order, or any stockholder or stockholders
       owning in the aggregate not less than ten percent (10%) of the total
       number of shares of Preferred Stock outstanding, irrespective of series,
       may request, the calling of special meeting of the holders of Preferred
       Stock, which meeting shall thereupon be called by the President, a Vice-
       President or the Secretary of the Corporation. Notice of such meeting and
       of any annual meeting at which holders of Preferred Stock are entitled to
       vote pursuant to this subparagraph (c)(iii)(C) shall be given to each
       holder of record of Preferred Stock by mailing a copy of such notice to
       him at his last address as the same appears on the books of the
       Corporation. Such meeting shall be called for a time not earlier than 20
       days and not later than 60 days after such order or request or in default
       of the calling of such meeting within 60 days after such order or
       request, such meeting may be called on similar notice by any stockholder
       or stockholders owning in the aggregate not less than ten percent (10%)
       of the total number of shares of Preferred Stock outstanding.
       Notwithstanding the provisions of this subparagraph (c)(iii)(C) no such
       special meeting shall be called during the period within 60 days
       immediately preceding the date fixed for the next annual meeting of the
       stockholders.

          (D) In any default period, the holders of Common Stock, and other
       classes of stock of the Corporation if applicable, shall continue to be
       entitled to elect the whole number of Directors until the holders of
       Preferred Stock shall have exercised their right to elect two (2)
       Directors voting as a class, after the exercise of which right (x) the
       Directors so elected by the holders of Preferred Stock shall continue in
       office until their successors shall have been elected by such holders or
       until the expiration of the default period, and (y) any vacancy in the
       Board of Directors may (except as provided in subparagraph (iii)(B) of
       this subsection (c)) be filled by vote of a majority of the remaining
       Directors theretofore elected by the holders of the class of stock which
       elected the Director whose office shall have become vacant. References in
       this paragraph (iii) to Directors elected by the holders of a particular
       class of stock shall include Directors elected by such Directors to fill
       vacancies as provided in clause (y) of the foregoing sentence.

          (E) Immediately upon the expiration of a default period, (x) the right
       of the holders of Preferred Stock as a class to elect Directors shall
       cease, (y) the term of any Directors elected by the holders of Preferred
       Stock as a class shall terminate, and (z) the number of Directors shall
       be such number as may be provided for in the Certificate of Incorporation
       or By-laws irrespective of any increase made pursuant to the provisions
       of subparagraph (iii)(B) of this subsection (c) (such number being
       subject, however, to change thereafter in any manner provided by law or
       in the Certificate of Incorporation or By-laws). Any vacancies in the
       Board of Directors effected by the provisions of clauses (y) and (z) in
       the preceding sentence may be filled by a majority of the remaining
       Directors.

          (iv) Except as set forth herein, holders of Series A Junior
     Participating Preferred Stock shall have no special voting rights and their
     consent shall not be required (except to the extent they are entitled to
     vote with holders of Common Stock as set forth herein) for taking any
     corporate action.

     (d) CERTAIN RESTRICTIONS.

       (i) Whenever quarterly dividends or other dividends or distributions
     payable on the Series A Junior Participating Preferred Stock as provided in
     subsection (b) are in arrears, thereafter and until all accrued and unpaid
     dividends and distributions, whether or not declared, on shares of 

                                       5
<PAGE>
 
     Series A Junior Participating Preferred Stock outstanding shall have been
     paid in full, the Corporation shall not

          (A) declare or pay dividends on, make any other distributions on, or
       redeem or purchase or otherwise acquire for consideration any shares of
       stock ranking junior (either as to dividends or upon liquidation,
       dissolution or winding up) to the Series A Junior Participating Preferred
       Stock;

          (B) declare or pay dividends on or make any other distributions on any
       shares of stock ranking on a parity (either as to dividends or upon
       liquidation, dissolution or winding up) with the Series A Junior
       Participating Preferred Stock, except dividends paid ratably on the
       Series A Junior Participating Preferred Stock and all such parity stock
       on which dividends are payable or in arrears in proportion to the total
       amounts to which the holders of all such shares are then entitled;

          (C) redeem or purchase or otherwise acquire for consideration shares
       of any stock ranking on a parity (either as to dividends or upon
       liquidation, dissolution or winding up) with the Series A Junior
       Participating Preferred Stock, provided that the Corporation may at any
       time redeem, purchase or otherwise acquire shares of any such parity
       stock in exchange for shares of any stock of the Corporation ranking
       junior (either as to dividends or upon dissolution, liquidation or
       winding up) to the Series A Junior Participating Preferred Stock; or

          (D) purchase or otherwise acquire for consideration any shares of
       Series A Junior Participating Preferred Stock, or any shares of stock
       ranking on a parity with the Series A Junior Participating Preferred
       Stock, except in accordance with a purchase offer made in writing or by
       publication (as determined by the Board of Directors) to all holders of
       such shares upon such terms as the Board of Directors, after
       consideration of the respective annual dividend rates and other relative
       rights and preferences of the respective series and classes, shall
       determine in good faith will result in fair and equitable treatment among
       the respective series or classes.

       (ii) The Corporation shall not permit any subsidiary of the Corporation
     to purchase or otherwise acquire for consideration any shares of stock of
     the Corporation unless the Corporation could, under paragraph (i) of this
     subsection (d), purchase or otherwise acquire such shares at such time and
     in such manner.

     (e) REACQUIRED SHARES.  Any shares of Series A Junior Participating
  Preferred Stock purchased or otherwise acquired by the Corporation in any
  manner whatsoever shall be retired and canceled promptly after the acquisition
  thereof. All such shares shall upon their cancellation become authorized but
  unissued shares of Preferred Stock and may be reissued as part of a new series
  of Preferred Stock to be created by resolution or resolutions of the Board of
  Directors, subject to the conditions and restrictions on issuance set forth
  herein.

     (f) LIQUIDATION, DISSOLUTION OR WINDING UP.

       (i) Upon any liquidation (voluntary or otherwise), dissolution or winding
     up of the Corporation, no distribution shall be made to the holders of
     shares of stock ranking junior (either as to dividends or upon liquidation,
     dissolution or winding up) to the Series A Junior Participating Preferred
     Stock unless, prior thereto, the holders of shares of Series A Junior
     Participating Preferred Stock shall have received $100 per share, plus an
     amount equal to accrued and unpaid dividends and distributions thereon,
     whether or not declared, to the date of such payment (the "SERIES A
     LIQUIDATION PREFERENCE"). Following the payment of the full 

                                       6
<PAGE>
 
     amount of the Series A Liquidation Preference, no additional distributions
     shall be made to the holders of shares of Series A Junior Participating
     Preferred Stock unless, prior thereto, the holders of shares of Common
     Stock shall have received an amount per share (the "COMMON ADJUSTMENT")
     equal to the quotient obtained by dividing (i) the Series A Liquidation
     Preference by (ii) 100 (as appropriately adjusted as set forth in paragraph
     (iii) below to reflect such events as stock splits, stock dividends and
     recapitalizations with respect to the Common Stock) (such number in clause
     (ii), the "ADJUSTMENT NUMBER"). Following the payment of the full amount
     of the Series A Liquidation Preference and the Common Adjustment in respect
     of all outstanding shares of Series A Junior Participating Preferred Stock
     and Common Stock, respectively, holders of Series A Junior Participating
     Preferred Stock and holders of shares of Common Stock shall receive their
     ratable and proportionate share of the remaining assets to be distributed
     in the ratio of the Adjustment Number to 1 with respect to such Series A
     Junior Participating Preferred Stock and Common Stock, on a per share
     basis, respectively.

       (ii) In the event, however, that there are not sufficient assets
     available to permit payment in full of the Series A Liquidation Preference
     and the liquidation preferences of all other series of preferred stock, if
     any, which rank on a parity with the Series A Junior Participating
     Preferred Stock, then such remaining assets shall be distributed ratably to
     the holders of such parity shares in proportion to their respective
     liquidation preferences. In the event, however, that there are not
     sufficient assets available to permit payment in full of the Common
     Adjustment, then such remaining assets shall be distributed ratably to the
     holders of Common Stock.

       (iii) In the event the Corporation shall at any time after the Rights
     Declaration Date (i) declare any dividend on Common Stock payable in shares
     of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii)
     combine the outstanding Common Stock into a smaller number of shares, then
     in each such case the Adjustment Number in effect immediately prior to such
     event shall be adjusted by multiplying such Adjustment Number by a fraction
     the numerator of which is the number of shares of Common Stock outstanding
     immediately after such event and the denominator of which is the number of
     shares of Common Stock that were outstanding immediately prior to such
     event.

     (g) CONSOLIDATION, MERGER, ETC.  In case the Corporation shall enter into
  any consolidation, merger, combination or other transaction in which the
  shares of Common Stock are exchanged for or changed into other stock or
  securities, cash and/or any other property, then in any such case the shares
  of Series A Junior Participating Preferred Stock shall at the same time be
  similarly exchanged or changed in an amount per share (subject to the
  provision for adjustment hereinafter set forth) equal to 100 times the
  aggregate amount of stock, securities, cash and/or any other property (payable
  in kind), as the case may be, into which or for which each share of Common
  Stock is changed or exchanged. In the event the Corporation shall at any time
  after the Rights Declaration Date (i) declare any dividend on Common Stock
  payable in shares of Common Stock, (ii) subdivide the outstanding Common
  Stock, or (iii) combine the outstanding Common Stock into a smaller number of
  shares, then in each such case the amount set forth in the preceding sentence
  with respect to the exchange or change of shares of Series A Junior
  Participating Preferred Stock shall be adjusted by multiplying such amount by
  a fraction the numerator of which is the number of shares of Common Stock
  outstanding immediately after such event and the denominator of which is the
  number of shares of Common Stock that were outstanding immediately prior to
  such event.

     (h) NO REDEMPTION.  The shares of Series A Junior Participating Preferred
  Stock shall not be redeemable.

     (i) RANKING.  The Series A Junior Participating Preferred Stock shall rank
 junior to all other series of the Corporation's Preferred Stock as to the
 payment of dividends and the distribution of assets, unless the terms of such
 series shall provide otherwise.

                                       7
<PAGE>
 
     (j) AMENDMENT.  The Certificate of Incorporation of the Corporation shall
  not be further amended in any manner which would materially alter or change
  the powers, preferences or special rights of the Series A Junior Participating
  Preferred Stock so as to affect them adversely without the affirmative vote of
  the holders of a majority or more of the outstanding shares of Series A Junior
  Participating Preferred Stock, voting separately as a class.

     (k) FRACTIONAL SHARES.  Series A Junior Participating Preferred Stock may
  be issued in fractions of a share which shall entitle the holder, in
  proportion to such holder's fractional shares, to exercise voting rights,
  receive dividends, participate in distributions and to have the benefit of all
  other rights of holders of Series A Junior Participating Preferred Stock.

  SECTION 4.4. COMMON STOCK.  Except as otherwise provided by this Certificate
of Incorporation or as otherwise from time to time provided by law, the holders
of Common Stock shall be entitled to one vote per share on all matters to be
voted on by the stockholders of the Corporation.

  SECTION 4.5.  SUBSTANTIAL STOCKHOLDER.

     (a) So long as any Person other than the Corporation or a Subsidiary
 thereof is (without giving effect to this Section 4.5(a)) the beneficial owner
 of capital stock representing 10% or more of the votes entitled to be cast by
 the holders of all outstanding shares of capital stock (a "SUBSTANTIAL
 STOCKHOLDER"), the record holders of the shares of capital stock beneficially
 owned by such Substantial Stockholder shall have limited voting rights on all
 matters, as follows: with respect to the shares of capital stock that would
 entitle such record holders in the aggregate to cast less than 10% of the votes
 entitled to be cast by the holders of all Outstanding shares of capital stock,
 such record holders shall be entitled to cast the vote per share specified in
 this Certificate of Incorporation; and with respect to the shares of capital
 stock that would otherwise entitle such record holders in the aggregate to cast
 10% or more of the votes entitled to be cast by the holders of all outstanding
 shares of capital stock, such record holders shall not be entitled to cast any
 votes for such shares, so that such record holders shall be entitled to cast
 with respect to all shares of capital stock held by such record holders in the
 aggregate only such number of votes that would equal (after giving effect to
 this Section 4.5(a)) one vote less than 10% of the votes entitled to be cast by
 all holders of outstanding shares of capital stock; provided, however, that the
 restriction on voting contained in this Section 4.5(a) shall not apply to any
 capital stock beneficially owned by any Substantial Stockholder whose
 acquisition or ownership of capital stock representing 10% or more of the votes
 entitled to be cast by the holders of all Outstanding shares of capital stock
 has been approved by the Wisconsin Insurance Commissioner. The aggregate voting
 power of such record holders, so limited, for all shares of capital stock
 beneficially owned by the Substantial Stockholder shall be allocated
 proportionately among such record holders as follows: for each such record
 holder, this allocation shall be accomplished by multiplying the aggregate
 voting power (after giving effect to the provisions of this Section 4.5(a)) of
 the Outstanding shares of capital stock beneficially owned by the Substantial
 Stockholder by a fraction the numerator of which is the number of votes that
 the shares of capital stock owned of record by such record holder would have
 entitled such record holder to cast were no effect given to this Section
 4.5(a), and the denominator of which is the total number of votes which all
 shares of capital stock beneficially owned by the Substantial Stockholder would
 have entitled their record holders to cast were no effect given to this Section
 4.5(a).

     (b) The Board of Directors by majority vote shall have the power and duty
 to determine for the purposes of this Article IV, on the basis of information
 known to them after reasonable inquiry, (i) whether a Person is a Substantial
 Stockholder, (ii) the number of shares of capital stock beneficially owned by
 any Person, (iii) whether a Person is an Affiliate or Associate of another,
 (iv) the Persons who may be deemed to be the record holders of shares
 beneficially owned by a Substantial Stockholder 

                                       8
<PAGE>
 
 and (v) such other matters with respect to which a determination is required
 under this Article IV. Any such determination made in good faith shall be
 binding and conclusive on all parties.

     (c) The Board of Directors shall have the right to demand that any Person
 who is reasonably believed to be a Substantial Stockholder (or to hold of
 record shares of capital stock beneficially owned by a Substantial Stockholder)
 supply the Corporation with complete information as to (i) the record holder or
 holders of all shares beneficially owned by such Person, (ii) the number of
 shares of capital stock beneficially owned by such Person and held of record by
 each such record holder, and (iii) any other factual matter relating to the
 applicability or effect of this Article IV, as may reasonably be requested of
 such Person, and such Person shall furnish such information within ten days
 after the receipt of such demand.

     (d) Nothing contained in this Article IV shall be construed to relieve any
  Substantial Stockholder from any fiduciary obligation imposed by law.

  SECTION 4.6.  QUORUM.  Except as otherwise provided in this Certificate of
Incorporation, the presence in person or by proxy of the holders of record of
shares of capital stock entitling the holders thereof to cast a majority of the
votes (after giving effect, if required, to the provisions of Section 4.5(a))
entitled to be cast by the holders of all Outstanding shares of capital stock
entitled to vote shall constitute a quorum at all meetings of the stockholders.

  SECTION 4.7.  MAJORITY VOTE.  If any class or series of the Corporation's
capital stock shall be entitled to more or less than one vote for any share, on
any matter for which such class or series is entitled to vote with one or more
other classes or series, together as one class, every reference in this
Certificate of Incorporation, the By-laws and in any relevant provision of law
to a majority or other proportion of stock shall refer to such majority or other
proportion of the votes of such stock.

  SECTION 4.8.  NO PREEMPTIVE RIGHTS.  Except as otherwise provided by this
Certificate of Incorporation or as otherwise from time to time provided by law,
no holder of shares of any class or series of capital stock of the Corporation
or of any security or obligation convertible into, or of any warrant, option or
right to subscribe for, purchase or otherwise acquire, shares of any class or
series of capital stock of the Corporation, whether now or hereafter authorized,
shall, as such holder, have any preemptive right to subscribe for, purchase or
otherwise acquire shares of any class or series of capital stock of the
Corporation or any security or obligation convertible into, or any warrant,
option or right to subscribe for, purchase or otherwise acquire, shares of any
class or series of capital stock of the Corporation, whether now or hereafter
authorized.

                                  Definitions
                                        
  As used in this Certificate of Incorporation, the following terms shall have
the following meanings:

  "AFFILIATE", with respect to any Person, means any other Person directly or
indirectly controlling, controlled by or under common control with, such Person.
For purposes of this definition, "CONTROL" (including, with correlative
meanings, the terms "CONTROLLING," "CONTROLLED BY" or "UNDER COMMON CONTROL
WITH"), as used with respect to any Person, shall mean the possession, directly
or indirectly, of the power to direct or cause the direction of the management
and policies of such Person, whether through the ownership of voting securities,
by contract, by common management or otherwise. A Person having a contract or
arrangement giving that Person control is deemed to be in control despite any
limitations placed by law on the validity of the contract or arrangement. A
corporation is deemed to be under 

                                       9
<PAGE>
 
common control with any corporation, regardless of ownership, if substantially
the same group of persons manage the two corporations.

  "ASSOCIATE", used to indicate a relationship with a specified Person, shall
mean (i) any Person (other than the Corporation or a Subsidiary) of which such
specified Person is an officer or partner or is, directly or indirectly, the
beneficial owner of 10% or more of the voting securities of such Person, (ii)
any trust or other estate in which such specified Person has a substantial
beneficial interest or as to which such specified Person serves as trustee or in
a similar fiduciary capacity, (iii) any relative or such spouse of such
specified Person or any relative of such spouse who has the same home as such
specified Person or who is a director or officer of the Corporation or any
Subsidiary, and (iv) any Person who is a director or officer of such specified
Person or any of its parents or subsidiaries (other than the Corporation or a
Subsidiary).

  A Person shall be deemed a "BENEFICIAL OWNER" of any shares of capital stock
of the Corporation (a) which such Person or any of its Affiliates or Associates
beneficially owns, directly or indirectly; (b) which such Person or any of its
Affiliates or Associates has, directly or indirectly, the right to vote pursuant
to any agreement, contract, arrangement or understanding, or (c) which are
beneficially owned, directly or indirectly, by any other Person with which such
Person or any of its Affiliates or Associates has any contract, agreement,
arrangement or understanding for the purpose of holding or voting of any capital
stock of the Corporation.

  "OUTSTANDING", when used in reference to shares of stock, shall mean issued
shares, excluding shares held in treasury.

  "PERSON" shall mean any individual, firm, corporation or other entity and
shall include any group comprised of any Person and any other Person with whom
such Person or any Affiliate or Associate of such Person has any agreement,
contract, arrangement or understanding, directly or indirectly, for the purpose
of acquiring, holding, voting or disposing of any shares of capital stock of the
Corporation.

  "SUBSIDIARY" shall mean any corporation of which a majority of any class of
equity securities is beneficially owned, directly or indirectly, by the
Corporation.

  "SUBSTANTIAL STOCKHOLDER" shall be defined as in Section 4.5 of this
Certificate of Incorporation.


                                   ARTICLE VI
                                        
                                   DIRECTORS
                                        
  Section 6.1.  WRITTEN BALLOT.  Elections of directors of the Corporation need
not be by written ballot, except and to the extent provided in the By-laws of
the Corporation.

  SECTION 6.2.  NO LIABILITY.  To the fullest extent permitted by the General
Corporation Law as it now exists and as it may hereafter be amended, no director
of the Corporation shall be personally liable to the Corporation or its
stockholders for monetary damages for any breach of fiduciary duty as a
director.

                                  ARTICLE VII
                                        
               INDEMNIFICATION OF DIRECTORS, OFFICERS AND OTHERS

  SECTION 7.1.  INDEMNIFICATION.  (a) The Corporation shall indemnify any person
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of the

                                       10
<PAGE>
 
Corporation) by reason of the fact that he is or was a director, officer,
employee or agent of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against expenses
(including attorneys fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with such action, suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in, or not opposed to, the best interests of the Corporation, and, with
respect to any criminal action or proceeding, had no reasonable cause to believe
his conduct was unlawful. The termination of any action, suit or proceeding by
judgment, order, settlement, conviction, or upon a false plea of nolo contendere
or its equivalent, shall not, of itself, create a presumption that the person
seeking indemnification did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

     (b) The Corporation shall indemnify any person who was or is a party or is
  threatened to be made a party to any threatened, pending or completed action
  or suit by or in the right of the Corporation to procure a judgment in its
  favor by reason of the fact that he is or was a director, officer, employee or
  agent of the Corporation, or is or was serving at the request of the
  Corporation as a director, officer, employee or agent of another corporation,
  partnership, joint venture, trust or other enterprise against expenses
  (including attorneys' fees) actually and reasonably incurred by him in
  connection with the defense or settlement of such action or suit if he acted
  in good faith and in a manner he reasonably believed to be in or not opposed
  to the best interests of the Corporation and except that no indemnification
  shall be made in respect of any claim, issue or matter as to which such person
  shall have been adjudged to be liable to the Corporation unless and only to
  the extent that the Court of Chancery of the State of Delaware or the court in
  which such action or suit was brought shall determine upon application that,
  despite the adjudication of liability but in view of all the circumstances of
  the case, such person is fairly and reasonably entitled to indemnity for such
  expenses which the Court of Chancery or such other court shall deem proper.

     (c) To the extent that a director, officer, employee or agent of the
  Corporation has been successful on the merits or otherwise in defense of any
  action, suit or proceeding referred to in Sections 7.1(a) and (b) or in
  defense of any claim, issue or matter therein, he shall be indemnified against
  expenses (including attorneys' fees) actually and reasonably incurred by him
  in connection therewith.

     (d) Any indemnification under Sections 7.1(a) and (b) (unless ordered by a
  court) shall be made by the Corporation only as authorized in the specific
  case upon a determination that indemnification of the director, officer,
  employee or agent is proper in the circumstances because he has met the
  applicable standard of conduct set forth in such Sections 7.1(a) and (b). Such
  determination shall be made (i) by the Board of Directors of the Corporation
  by a majority vote of a quorum consisting of directors who were not parties to
  such action, suit or proceeding, or (ii) if such a quorum is not obtainable,
  or, even if obtainable, a quorum of disinterested directors so directs, by
  independent legal counsel in a written opinion, or (iii) by the stockholders
  of the Corporation.

     (e) Expenses incurred by a director or officer of the Corporation in
  defending a civil or criminal action, suit or proceeding may be paid by the
  Corporation in advance of the final disposition of such action, suit or
  proceeding upon receipt of an undertaking by or on behalf of such director or
  officer to repay such amount if it shall ultimately be determined that he is
  not entitled to be indemnified by the Corporation authorized in this Article
  VII. Such expenses incurred by other employees and agents may be so paid upon
  such terms and conditions, if any, as the Board of Directors of the
  Corporation deems appropriate.

     (f) The indemnification and advancement of expenses provided by, or granted
  pursuant to, the other sections of this Article VII shall not be deemed
  exclusive of any other rights to which those seeking indemnification or
  advancement of expenses may be entitled under any law, by-law, 

                                       11
<PAGE>
 
  agreement, vote of stockholders or disinterested directors or otherwise, both
  as to action in an official capacity and as to action in another capacity
  while holding such office.

     (g) The Corporation may purchase and maintain insurance on behalf of any
  person who is or was a director, officer, employee or agent of the
  Corporation, or is or was serving at the request of the Corporation as a
  director, officer, employee or agent of another corporation, partnership,
  joint venture, trust or other enterprise against any liability asserted
  against him and incurred by him in any such capacity, or arising out of his
  status as such, whether or not the Corporation would have the power to
  indemnify him against such liability under the provisions of Section 145 of
  the General Corporation Law.

     (h) For purposes of this Article VII, references to "THE CORPORATION" shall
  include, in addition to the resulting corporation, any constituent corporation
  (including any constituent of a constituent) absorbed in a consolidation or
  merger which, if its separate existence had continued, would have had power
  and authority to indemnify its directors, officers, employees or agents so
  that any person who is or was a director, officer, employee or agent of such
  constituent corporation, or is or was serving at the request of such
  constituent corporation as a director, officer, employee or agent of another
  corporation, partnership, joint venture, trust or other enterprise, shall
  stand in the same position under the provisions of this Article VII with
  respect to the resulting or surviving corporation as he would have with
  respect to such constituent corporation if its separate existence had
  continued.

     (i) For purposes of this Article VII, references to "OTHER ENTERPRISES"
  shall include employee benefit plans; references to "fines" shall include any
  excise taxes assessed on a person with respect to an employee benefit plan;
  and references to "SERVING AT THE REQUEST OF THE CORPORATION" shall include
  any service as a director, officer, employee or agent of the Corporation which
  imposes duties on, or involves service by, such director, officer, employee or
  agent with respect to any employee benefit plan, its participants or
  beneficiaries; and a person who acted in good faith and in a manner he
  reasonably believed to be in the interest of the participants and
  beneficiaries of an employee benefit plan shall be deemed to have acted in a
  manner "NOT OPPOSED TO THE BEST INTERESTS OF THE CORPORATION" as referred to
  in this Article VII.

     (j) The indemnification and advancement of expenses provided by, or granted
  pursuant to, this Article VII shall, unless otherwise provided when authorized
  or ratified, continue as to a person who has ceased to be a director, officer,
  employee or agent and shall inure to the benefit of the heirs, executors and
  administrators of such a person.


                                  ARTICLE VIII
                                        
                                    BY-LAWS

     The directors of the Corporation shall have the power to adopt, amend or
repeal the By-laws of the Corporation.

                                   ARTICLE IX
                                        
                                 REORGANIZATION

     Whenever a compromise or arrangement is proposed between this Corporation
and its creditors or any class of them and/or between this Corporation and its
stockholders or any class of them, any court of equitable jurisdiction within

3.  ADMINISTRATION OF THE PLAN

  (a)  POWER AND AUTHORITY OF THE COMMITTEE.  The Plan shall be administered by
the Committee, which shall have full power and authority, subject to the express
provisions hereof:

    (i) to select Participants from the Eligible Individuals;

    (ii) to make Awards in accordance with the Plan;

    (iii) to determine the number of shares of Common Stock subject to each
  Award or the cash amount payable in connection with an Award;

    (iv) to determine the terms and conditions of each Award, including, without
  limitation, those related to vesting, forfeiture, payment and exercisability,
  and the effect, if any, of a Participant's termination of employment with the
  Company, and including the authority to amend the terms and conditions of an
  Award after the granting thereof to a Participant in a manner that is not,
  without the consent of the Participant, prejudicial to the rights of such
  Participant in such Award;

    (v) to specify and approve the provisions of the Award Agreements delivered
  to Participants in connection with their Awards;

    (vi) to construe and interpret any Award Agreement delivered under the Plan;

    (vii) to prescribe, amend and rescind rules and procedures relating to the
  Plan;

    (viii) to vary the terms of Awards to take account of tax, securities law
  and other regulatory requirements of foreign jurisdictions;

    (ix) subject to the provisions of the Plan and subject to such additional
  limitations and restrictions as the Committee may impose, to delegate to one
  or more officers of the Company some or all of its authority under the Plan;

    (x) to employ such legal counsel, independent auditors and consultants as it
  deems desirable for the administration of the Plan and to rely upon any
  opinion or computation received therefrom; and

    (xi) to make all other determinations and to formulate such procedures as
  may be necessary or advisable for the administration of the Plan.

  (b)  PLAN CONSTRUCTION AND INTERPRETATION.  The Committee shall have full
power and authority, subject to the express provisions hereof, to construe and
interpret the Plan.

  (c)  DETERMINATIONS OF COMMITTEE FINAL AND BINDING.  All determinations by the
Committee in carrying out and administering the Plan and in construing and
interpreting the Plan shall be final, binding and conclusive for all purposes
and upon all persons interested herein.

  (d)  DELEGATION OF AUTHORITY.  The Committee may, but need not, from time to
time delegate some or all of its authority under the Plan to an Administrator
consisting of one or more members of the Committee or of one or more officers of
the Company; provided, however, that the Committee may not delegate its
authority (i) to make Awards to Eligible Individuals who are officers of the
Company who are 

                                       3
<PAGE>
 
delegated authority by the Committee hereunder, or (ii) under Sections 3(b) and
16 of the Plan. Any delegation hereunder shall be subject to the restrictions
and limits that the Committee specifies at the time of such delegation or
thereafter. Nothing in the Plan shall be construed as obligating the Committee
to delegate authority to an Administrator, and the Committee may at any time
rescind the authority delegated to an Administrator appointed hereunder or
appoint a new Administrator. At all times, the Administrator appointed under
this Section 3(d) shall serve in such capacity at the pleasure of the Committee.
Any action undertaken by the Administrator in accordance with the Committee's
delegation of authority shall have the same force and effect as if undertaken
directly by the Committee, and any reference in the Plan to the Committee shall,
to the extent consistent with the terms and limitations of such delegation, be
deemed to include a reference to the Administrator.

  (e)  LIABILITY OF COMMITTEE.  No member of the Committee shall be liable for
any action nor determination made in good faith, and the members of the
Committee shall be entitled to indemnification and reimbursement in the manner
provided in Ambac's Certificate of Incorporation as it may be amended from time
to time. In the performance of its responsibilities with respect to the Plan,
the Committee shall be entitled to rely upon information and advice furnished by
the Company's officers, the Company's accountants, the Company's counsel and any
other party the Committee deems necessary, and no member of the Committee shall
be liable for any action taken or not taken in reliance upon any such advice.

  (f)  ACTION BY THE BOARD.  Anything in the Plan to the contrary
notwithstanding, any authority or responsibility which, under the terms of the
Plan, may be exercised by the Committee may alternatively be exercised by the
Board.

4.  EFFECTIVE DATE AND TERM

  The Plan shall become effective upon its adoption by the Board subject to its
approval by the stockholders of Ambac. Prior to such stockholder approval, the
Committee may grant Awards conditioned on stockholder approval. If such
stockholder approval is not obtained at or before the first annual meeting of
stockholders to occur after the adoption of the Plan by the Board (including any
adjournment or adjournments thereof), the Plan and any Awards made thereunder
shall terminate ab initio and be of no further force and effect. In no event
shall any Awards be made under the Plan after the seventh anniversary of the
date of stockholder approval.

5.  SHARES OF COMMON STOCK SUBJECT TO THE PLAN

  (a)  GENERAL.  Subject to adjustment as provided in Section 15(b) hereof, the
number of shares of Common Stock that may be issued pursuant to Awards under the
Plan (the "SECTION 5 LIMIT") shall not exceed, in the aggregate:

     (I) 2,750,000 shares; plus

    (II) the number of shares of Common Stock that remain available for issuance
  under the Predecessor Plan as of the date this Plan is approved by the
  stockholders of the Company (increased by any shares of Common Stock subject
  to any award (or portion thereof) outstanding under the Predecessor Plan on
  such date which lapses, expires or is otherwise terminated without the
  issuance of such shares or is settled by the delivery of consideration other
  than shares).

Shares issued under this Plan may be either authorized but unissued shares,
treasury shares or any combination thereof.

  (b)  RULES APPLICABLE TO DETERMINING SHARES AVAILABLE FOR ISSUANCE.  For
purposes of determining the number of shares of Common Stock that remain
available for issuance, the following shares shall be added back to the Section
5 Limit and again be available for Awards:

                                       4
<PAGE>
 
    (x) The number of shares tendered to pay the exercise price of a Stock
  Option or other Award; and

    (y) The number of shares withheld from any Award to satisfy a Participant's
  tax withholding obligations or, if applicable, to pay the exercise price of a
  Stock Option or other Award.

In addition, any shares underlying Substitute Awards shall not be counted
against the Section 5 Limit and shall not be subject to Section 5(c) below.

  (c)  SPECIAL LIMITS.  Anything to the contrary in Section 5(a) above
notwithstanding, but subject to Section 15(b) below, the following special
limits shall apply to shares of Common Stock available for Awards under the
Plan:

    (i) The maximum number of shares that may be issued in the form of Stock
  Awards, or issued upon settlement of Restricted Stock Units or Other Awards,
  shall equal 800,000 shares, of which no more than a number of shares equal to
  10% of the Section 5 Limit shall be in the form of Other Awards, provided,
  however, that any such Stock Awards, Restricted Stock Units or Other Awards
  that are issued in lieu of cash compensation that otherwise would be paid to a
  Participant, or in satisfaction of any other obligation owed by the Company to
  a Participant, shall not be counted against such limitation; and

    (ii) The maximum number of shares of Common Stock that may be subject to
  Stock Options or Stock Appreciation Rights granted to any Eligible Individual
  in any fiscal year of the Company shall equal 200,000 shares plus any shares
  which were available under this Section 5(c)(ii) for Awards of Stock Options
  or Stock Appreciation Rights to such Eligible individual in any prior fiscal
  year but which were not covered by such Awards.

  (d)  NO FURTHER AWARDS UNDER PREDECESSOR PLAN.  From and after the date this
Plan is approved by the stockholders of the Company, no further awards shall be
made under the Predecessor Plan.

6.  ELIGIBLE INDIVIDUALS

  Awards may be granted by the Committee to individuals ("ELIGIBLE INDIVIDUALS")
who are officers or other key employees of the Company. Members of the Committee
will not be eligible to receive Awards under the Plan. An individual's status as
an Administrator will not affect his or her eligibility to participate in the
Plan.

7.  AWARDS IN GENERAL

  (a)  TYPES OF AWARD AND AWARD AGREEMENT.  Awards under the Plan may consist of
Stock Options, Stock Appreciation Rights, Stock Awards, Restricted Stock Units,
Performance Units or Other Awards. Any Award described in Sections 8 through 13
of the Plan may be granted singly or in combination or tandem with any other
Award, as the Committee may determine. Awards may be made in combination with,
in replacement of, or as alternatives to grants of rights under any other
employee compensation plan of the Company, including the plan of any acquired
entity, or may be granted in satisfaction of the Company's obligations under any
such plan.

  (b)  TERMS SET FORTH IN AWARD AGREEMENT.  The terms and provisions of an Award
shall be set forth in a written Award Agreement approved by the Committee and
delivered or made available to the Participant as soon as practicable following
the date of the award. The vesting, exercisability, payment and other
restrictions applicable to an Award (which may include, without limitation,
restrictions on transferability or provision for mandatory resale to the
Company) shall be determined by the Committee and set forth in the applicable
Award Agreement. Notwithstanding the foregoing, the Committee may 

                                       5
<PAGE>
 
accelerate (i) the vesting or payment of any Award, (ii) the lapse of
restrictions on any Award or (iii) the date on which any Stock Option, Stock
Appreciation Right or other Award first becomes exercisable.

  (c)  TERMINATION OF EMPLOYMENT AND CHANGE IN CONTROL.  The Committee shall
also have full authority to determine and specify in the applicable Award
Agreement the effect, if any, that a Participant's termination of employment for
any reason will have on the vesting, exercisability, payment or lapse of
restrictions applicable to an Award. The date of a Participant's termination of
employment for any reason shall be determined in the sole discretion of the
Committee. Similarly, the Committee shall have full authority to determine the
effect, if any, of a change in control of Ambac on the vesting, exercisability,
payment or lapse of restrictions applicable to an Award, which effect may be
specified in the applicable Award Agreement or determined at a subsequent time.

  (d)  DIVIDENDS AND DIVIDEND EQUIVALENTS.  The Committee may provide
Participants with the right to receive dividends or payments equivalent to
dividends or interest with respect to an outstanding Awards, which payments can
either be paid currently or deemed to have been reinvested in shares of Common
Stock, and can be made in Common Stock, cash or a combination thereof, as the
Committee shall determine.

8.  STOCK OPTIONS

  (a)  TERMS OF STOCK OPTIONS GENERALLY.  A Stock Option shall entitle the
Participant to whom the Stock Option was granted to purchase a specified number
of shares of Common Stock during a specified period at a price that is
determined in accordance with Section 8(b) below. Stock Options may be either
Nonqualified Stock Options or Incentive Stock Options. The Committee will fix
the vesting and exercisability conditions applicable to a Stock Option, provided
that no Stock Option shall vest sooner than one year from the date of grant
(subject to early vesting, if so provided by the Committee, upon death,
disability, termination of employment or a change in control of the Company),
but provided, further, that such minimum vesting period shall not apply to any
Restoration Option.

  (b)  EXERCISE PRICE.  The exercise price per share of Common Stock purchasable
under a Stock Option shall be fixed by the Committee at the time of grant or,
alternatively, shall be determined by a method specified by the Committee at the
time of grant; provided, however, that the exercise price per share shall be no
less than 100% of the Fair Market Value per share on the date of grant (or it
the exercise price is not fixed on the date of grant, then on such date as the
exercise price is fixed); and provided further, that, except as provided in
Section 15(b) below, the exercise price per share of Common Stock applicable to
a Stock Option may not be adjusted or amended, including by means of amendment,
cancellation or the replacement of such Stock Option with a subsequently awarded
Stock Option. Notwithstanding the foregoing, the exercise price per share of a
Stock Option that is a Substitute Award may be less than the Fair Market Value
per share on the date of award, provided that the excess of:

    (i) the aggregate Fair Market Value (as of the date such Substitute Award is
  granted) of the shares of Common Stock subject to the Substitute Award, over

   (ii) the aggregate exercise price thereof,

  does not exceed the excess of:

  (iii) the aggregate fair market value (as of the time immediately preceding
  the transaction giving rise to the Substitute Award, such fair market value to
  be determined by the Committee) of the shares of the predecessor entity that
  were subject to the award assumed or substituted for by the Company, over

   (iv) the aggregate exercise price of such shares.

                                       6
<PAGE>
 
  (c)  OPTION TERM.  The term of each Stock Option shall be fixed by the
Committee and shall not exceed ten years from the date of grant.

  (d)  METHOD OF EXERCISE.  Subject to the provisions of the applicable Award
Agreement, the exercise price of a Stock Option may be paid in cash or
previously owned shares or a combination thereof and, if the applicable Award
Agreement so provides, in whole or in part through the withholding of shares
subject to the Stock Option with a value equal to the exercise price. In
accordance with the rules and procedures established by the Committee for this
purpose, the Stock Option may also be exercised through a "cashless exercise"
procedure approved by the Committee involving a broker or dealer approved by the
Committee, that affords Participants the opportunity to sell immediately some or
all of the shares underlying the exercised portion of the Stock Option in order
to generate sufficient cash to pay the Stock Option exercise price and/or to
satisfy withholding tax obligations related to the Stock Option.

9.  STOCK APPRECIATION RIGHTS

  (a)  GENERAL.  A Stock Appreciation Right shall entitle a Participant to
receive, upon satisfaction of the conditions to the payment specified in the
applicable Award Agreement, an amount equal to the excess, if any, of the Fair
Market Value on the exercise date of the number of shares of Common Stock for
which the Stock Appreciation Right is exercised, over the exercise price for
such Stock Appreciation Right specified in the applicable Award Agreement. The
exercise price per share of Common Stock covered by a Stock Appreciation Right
shall be fixed by the Committee at the time of grant or, alternatively, shall be
determined by a method specified by the Committee at the time of grant;
provided, however, that, except as provided in Section 9(b) below, the exercise
price per share shall be no less than 100% of the Fair Market Value per share on
the date of grant (or if the exercise price is not fixed on the date of grant,
then on such date as the exercise price is fixed); and provided further, that,
except as provided in Section 15(b) below, the exercise price per share of
Common Stock subject to a Stock Appreciation Right may not be adjusted or
amended, including by means of amendment, cancellation or the replacement of
such Stock Appreciation Right with a subsequently awarded Stock Appreciation
Right. Notwithstanding the foregoing, the exercise price per share of a Stock
Appreciation Right that is a Substitute Award may be less than the Fair Market
Value per share on the date of award, provided, that such exercise price is not
less than the minimum exercise price that would be permitted for an equivalent
Stock Option as determined in accordance with Section 8(b) above. At the sole
discretion of the Committee, payments to a Participant upon exercise of a Stock
Appreciation Right may be made in cash, in shares of Common Stock having an
aggregate Fair Market Value as of the date of exercise equal to such amount, or
in a combination of cash and shares having an aggregate value as of the date of
exercise equal to such amount.

  (b)  STOCK APPRECIATION RIGHTS IN TANDEM WITH STOCK OPTIONS.  A Stock
Appreciation Right may be granted alone or in addition to other Awards, or in
tandem with a Stock Option. A Stock Appreciation Right granted in tandem with a
Stock Option may be granted either at the same time as such Stock Option or
subsequent thereto. If granted in tandem with a Stock Option, a Stock
Appreciation Right shall cover the same number of shares of Common Stock as
covered by the Stock Option (or such lesser number of shares as the Committee
may determine) and shall be exercisable only at such time or times and to the
extent the related Stock Option shall be exercisable, and shall have the same
term and exercise price as the related Stock Option (which, in the case of a
Stock Appreciation Right granted after the grant of the related Stock Option,
may be less than the Fair Market Value per share on the date of grant of the
tandem Stock Appreciation Right).  Upon exercise of a Stock Appreciation Right
granted in tandem with a Stock Option, the related Stock Option shall be
canceled automatically to the extent of the number of shares covered by such
exercise; conversely, if the related Stock Option is exercised as to some or all
of the shares covered by the tandem grant, the tandem Stock Appreciation Right
shall be canceled automatically to the extent of the number of shares covered by
the Stock Option exercise.

10.  STOCK AWARDS

                                       7
<PAGE>
 
  (a)  GENERAL.  A Stock Award shall consist of one or more shares of Common
Stock granted to a Participant for no consideration other than the provision of
services (or, if required by applicable law in the reasonable judgment of the
Company, for payment of the par value of such shares). Stock Awards shall be
subject to such restrictions (if any) on transfer or other incidents of
ownership for such periods of time, and shall be subject to such conditions of
vesting, as the Committee may determine and as shall be set forth in the
applicable Award Agreement.

  (b)  DISTRIBUTIONS.  Any shares of Common Stock or other securities of the
Company received by a Participant to whom a Stock Award has been granted as a
result of a stock distribution to holders of Common Stock or as a stock dividend
on Common Stock shall be subject to the same terms, conditions and restrictions
as such Stock Award.

11.  RESTRICTED STOCK UNITS

  An Award of Restricted Stock Units shall consist of a grant of units, each of
which represents the right of the Participant to receive one share of Common
Stock, subject to the terms and conditions established by the Committee in
connection with the Award and set forth in the applicable Award Agreement. Upon
satisfaction of the conditions to vesting and payment specified in the
applicable Award Agreement, Restricted Stock Units will be payable, at the
discretion of the Committee, in Common Stock, in cash equal to the Fair Market
Value of the shares subject to such Restricted Stock Units, or in a combination
of Common Stock and cash.  Restricted Stock Units that are granted in respect to
individual or corporate performance shall vest no sooner than one year from the
date of grant, and Restricted Stock Units that are granted in connection with
hiring or retention arrangements between the Company and a Participant shall
vest no sooner than three years from the date of grant (subject, in either case,
to early vesting, if so provided by the Committee, upon death, disability,
termination of employment or a change in control of the Company).

12.  PERFORMANCE UNITS

  Performance units may be granted as fixed or variable share- or dollar-
denominated units subject to such conditions of vesting and time of payment as
the Committee may determine and as shall be set forth in the applicable Award
Agreement relating to such Performance Units. Performance Units may be paid in
Common Stock, cash or a combination of Common Stock and cash, as the Committee
may determine.

13.  OTHER AWARDS

  The Committee shall have the authority to specify the terms and provisions of
other forms of equity-based or equity-related Awards not described above which
the Committee determines to be consistent with the purpose of the Plan and the
interests of the Company, which Awards may provide for cash payments based in
whole or in part on the value or future value of Common Stock, for the
acquisition or future acquisition of Common Stock, or any combination thereof.
Other Awards shall also include cash payments (including the cash payment of
dividend equivalents) under the Plan which may be based on one or more criteria
determined by the Committee which are unrelated to the value of Common Stock and
which may be granted in tandem with, or independent of, other Awards under the
Plan.

14.  CERTAIN RESTRICTIONS

  (a)  TRANSFERS.  Unless the Committee determines otherwise, no Award shall be
transferable other than by will or by the laws of descent and distribution or
pursuant to a domestic relations order; provided, however, that the Committee
may, in its discretion and subject to such terms and conditions as it shall
specify, permit the transfer of an Award for no consideration to a Participant's
family members or to one or more trusts or partnerships established in whole or
in part for the benefit of one or more of such family members (collectively,
"PERMITTED TRANSFEREES"). Any Award transferred to a Permitted Transferee shall
be further transferable only by will or the laws of descent and distribution or,
for no consideration, to 

                                       8
<PAGE>
 
another Permitted Transferee of the Participant. The Committee may in its
discretion permit transfers of Awards other than those contemplated by this
Section.

  (b)  EXERCISE.  During the lifetime of the Participant, a Stock Option, Stock
Appreciation Right or similar-type Other Award shall be exercisable only by the
Participant or by a Permitted Transferee to whom such Stock Option, Stock
Appreciation Right or Other Award has been transferred in accordance with
Section 14(a).

15.  RECAPITALIZATION OR REORGANIZATION

  (a)  AUTHORITY OF THE COMPANY AND STOCKHOLDERS.  The existence of the Plan,
the Award Agreements and the Awards granted hereunder shall not affect or
restrict in any way the right or power of the Company or the stockholders of the
Company to make or authorize any adjustment, recapitalization, reorganization or
other change in the Company's capital structure or its business, any merger or
consolidation of the Company, any issue of stock or of options, warrants or
rights to purchase stock or of bonds, debentures, preferred or prior preference
stocks whose rights are superior to or affect the Common Stock or the rights
thereof or which are convertible into or exchangeable for Common Stock, or the
dissolution or liquidation of the Company, or any sale or transfer of all or any
part of its assets or business, or any other corporate act or proceeding,
whether of a similar character or otherwise.

  (b)  CHANGE IN CAPITALIZATION.  Notwithstanding any provision of the Plan or
any Award Agreement, the number and kind of shares authorized for issuance under
Section 5(a) above, including the maximum number of shares available under the
special limits provided for in Section 5(c) above, may be equitably adjusted in
the sole discretion of the Committee in the event of a stock split, stock
dividend, recapitalization, reorganization, merger, consolidation, extraordinary
dividend, split-up, spin-off, combination, exchange of shares, warrants or
rights offering to purchase Common Stock at a price substantially below Fair
Market Value or other similar corporate event affecting the Common Stock in
order to preserve, but not increase, the benefits or potential benefits intended
to be made available under the Plan. In addition, upon the occurrence of any of
the foregoing events, the number of outstanding Awards and the number and kind
of shares subject to any outstanding Award and the purchase price per share, if
any, under any outstanding Award may be equitably adjusted (including by payment
of cash to a Participant) in the sole discretion of the Committee in order to
preserve the benefits or potential benefits intended to be made available to
Participants granted Awards. Such adjustments shall be made by the Committee,
whose determination as to what adjustments shall be made, and the extent
thereof, shall be final. Unless otherwise determined by the Committee, such
adjusted Awards shall be subject to the same vesting schedule and restrictions
to which the underlying Award is subject.

16.  AMENDMENTS

  The Board or Committee may at any time and from time to time alter, amend,
suspend or amend the Plan in whole or in part; provided, however, that any
amendment which under the requirements of any applicable law or stock exchange
rule must be approved by the stockholders of the Company shall not be effective
unless and until such stockholder approval has been obtained in compliance with
such law or rule; and provided further, that, except as contemplated by Section
15(b) above, the Board or Committee may not, without the approval of the
Company's stockholders, increase the maximum number of shares issuable under the
Plan or reduce the exercise price of a Stock Option or Stock Appreciation Right.
No termination or amendment of the Plan may, without the consent of the
Participant to whom an Award has been granted, adversely affect the rights of
such Participant under such Award. Notwithstanding any provision herein to the
contrary, the Board or Committee shall have broad authority to amend the Plan or
any Award under the Plan to take into account changes in applicable tax laws,
securities laws, accounting rules and other applicable state and federal laws.

17.  MISCELLANEOUS

                                       9
<PAGE>
 
  (a)  TAX WITHHOLDING.  The Company may require any individual entitled to
receive a payment in respect of an Award to remit to the Company, prior to such
payment, an amount sufficient to satisfy any Federal, state or local tax
withholding requirements. The Company shall also have the right to deduct from
all cash payments made pursuant to or in connection with any Award any Federal,
state or local taxes required to be withheld with respect to such payments. In
the case of an Award payable in shares of Common Stock, the Company may permit
such individual to satisfy, in whole or in part, such obligation to remit taxes
by directing the Company to withhold shares of Common Stock that would otherwise
be received by such individual, pursuant to such rules as the Committee may
establish from time to time.

  (b)  NO RIGHT TO GRANTS OR EMPLOYMENT.  No Eligible Individual or Participant
shall have any claim or right to receive grants of Awards under the Plan.
Nothing in the Plan or in any Award or Award Agreement shall confer upon any
employee of the Company any right to continued employment with the Company or
interfere in any way with the right of the Company to terminate the employment
of any of its employees at any time, with or without cause.

  (c)  OTHER COMPENSATION.  Nothing in this Plan shall preclude or limit the
ability of the Company to pay any compensation to a Participant under the
Company's other compensation and benefit plans and programs.

  (d)  OTHER EMPLOYEE BENEFIT PLANS.  Payments received by a Participant under
any Award made pursuant to the Plan shall not be included in, nor have any
effect on, the determination of benefits under any other employee benefit plan
or similar arrangement provided by the Company, unless otherwise specifically
provided for under the terms of such plan or arrangement or by the Committee.

  (e)  UNFUNDED PLAN.  The Plan is intended to constitute an unfunded plan for
incentive compensation. Prior to the payment or settlement of any Award, nothing
contained herein shall give any Participant any rights that are greater than
those of a general creditor of the Company. In its sole discretion, the
Committee may authorize the creation of trusts or other arrangements to meet the
obligations created under the Plan to deliver Common Stock or payments in lieu
thereof with respect to awards hereunder.

  (f)  SECURITIES LAW RESTRICTIONS.  The Committee may require each Eligible
Individual purchasing or acquiring shares of Common Stock pursuant to a Stock
Option or other Award under the Plan to represent to and agree with the Company
in writing that such Eligible Individual is acquiring the shares for investment
and not with a view to the distribution thereof. All certificates for shares of
Common Stock delivered under the Plan shall be subject to such stock-transfer
orders and other restrictions as the Committee may deem advisable under the
rules, regulations, and other requirements of the Securities and Exchange
Commission, any exchange upon which the Common Stock is then listed, and any
applicable federal or state securities law, and the Committee may cause a legend
or legends to be put on any such certificates to make appropriate reference to
such restrictions. No shares of Common Stock shall be issued hereunder unless
the Company shall have determined that such issuance is in compliance with, or
pursuant to an exemption from, all applicable federal and state securities laws.

  (g)  COMPLIANCE WITH RULE 16B-3.  Notwithstanding anything contained in the
Plan or in any Award Agreement to the contrary, if the consummation of any
transaction under the Plan would result in the possible imposition of liability
on a Participant pursuant to Section 16(b) of the Exchange Act, the Committee
shall have the right, in its sole discretion, but shall not be obligated, to
defer such transaction or the effectiveness of such action to the extent
necessary to avoid such liability, but in no event for a period longer than six
months.

  (h)  AWARD AGREEMENT.  In the event of any conflict or inconsistency between
the Plan and any Award Agreement, the Plan shall govern, and the Award Agreement
shall be interpreted to minimize or eliminate any such conflict or
inconsistency.

  (i)  EXPENSES.  The costs and expenses of administering the Plan shall be
borne by the Company.

                                       10
<PAGE>
 
  (j)  APPLICATION OF FUNDS.  The proceeds received from the Company from the
sale of Common Stock or other securities pursuant to Awards will be used for
general corporate purposes.

  (k)  APPLICABLE LAW.  Except as to matters of federal law, the Plan and all
actions taken thereunder shall be governed by and construed in accordance with
the laws of the State of Delaware without giving effect to conflicts of law
principles.

</TABLE>



(1)  As of September 30, 1997, approximately 4,319,000 stock options, restricted
     shares and restricted stock units had been granted and were outstanding.
     Based upon various exercise prices, the total consideration for the options
     and restricted stock units will be approximately $93.8 million. The
     dilution would be the equivalent of approximately 2,019,000 shares, using
     the treasury stock method, based upon an average value of $40.764 per
     share.

(2)  In accordance with Accounting Principles Board Opinion No. 15, any
     reduction of less than 3% need not be considered as dilution. Accordingly,
     the consolidated statements of operations on page 4 of this report reflect
     net income per common share of $0.87 and $2.35 for the three and nine
     months ended September 30, 1997.

                  CONSOLIDATED UNAUDITED FINANCIAL STATEMENTS
                AS OF SEPTEMBER 30, 1997 AND DECEMBER 31, 1996

AMBAC ASSURANCE CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED UNAUDITED FINANCIAL STATEMENTS


     (1)  BASIS OF PRESENTATION

     Ambac Assurance Corporation ("Ambac Assurance") is a leading insurer of
municipal and structured finance obligations and has been assigned triple-A
claims-paying ability ratings, the highest ratings available from Moody's
Investors Service, Inc., Standard & Poor's Ratings Group, Fitch Investors
Service, L.P., and Nippon Investors Services, Inc. Financial guarantee insurance
underwritten by Ambac Assurance guarantees payment when due of the principal of
and interest on the obligation insured. In the case of a default on the insured
obligation, payments under the insurance policy may not be accelerated by the
policyholder without Ambac Assurance's consent. As of September 30, 1997, Ambac
Assurance's net insurance in force (principal and interest) was $249.4 billion.
Ambac Assurance is a wholly-owned subsidiary of Ambac Financial Group, Inc.,
which is a holding company that provides through its affiliates financial
guarantee insurance and financial services to clients in both the public and
private sectors.

     American Municipal Bond Holding Company ("AMBH"), a wholly-owned subsidiary
of Ambac Assurance, is a holding company for certain real estate interests.

     During the first quarter of 1997, Ambac Assurance established a new
subsidiary in the United Kingdom, AMBAC Insurance UK Limited ("AMBAC UK"), which
was authorized to conduct certain classes of general insurance business in the
United Kingdom. As of February 4, 1997, AMBAC UK is the primary vehicle for the
issuance of financial guarantee insurance policies in the United Kingdom and
Europe.

     Ambac Assurance, as the sole limited partner, owns 90% of the total
partnership interests of Ambac Financial Services, Limited Partnership ("AFS"),
a limited partnership which provides interest rate swaps primarily to states,
municipalities and municipal authorities. The sole general partner of AFS, Ambac
Financial Services Holdings, Inc., a wholly-owned subsidiary Ambac Financial
Group, Inc., owns a general partnership interest representing 10% of the total
partnership interest in AFS.

          Ambac Assurance's consolidated unaudited interim financial statements
have been prepared on the basis of generally accepted accounting principles
("GAAP") and, in the opinion of management, reflect all adjustments, consisting
only of normal recurring adjustments, necessary for a fair presentation of the
Company's financial condition, results of operations and cash flows for the
periods presented. The preparation of financial statements in conformity with
GAAP requires management to make estimates and assumptions that affect the
reported amounts of assets and liabilities and disclosures of contingent assets
and liabilities at the date of the financial statements and the reported
revenues and expenses during the reporting period. Actual results could differ
from those estimates. The results of operations for the nine months ended
September 30, 1997 may not be indicative of the results that may be expected for
the full year ending December 31, 1997. These financial statements and notes
should be read in conjunction with the financial statements and notes included
in the audited consolidated financial statements of Ambac Assurance Corporation
and its subsidiaries as of December 31, 1996 and 1995, and for each of the years
in the three-year period ended December 31, 1996.
