                                     PART I
 
ITEM 1.  BUSINESS
 
GENERAL
 
     CMAC Investment Corporation (the "Company") provides, through its wholly
owned subsidiary, Commonwealth Mortgage Assurance Company ("CMAC"), private
mortgage insurance coverage in the United States on residential mortgage loans.
Private mortgage insurance protects mortgage lenders and investors from
default-related losses on residential first mortgage loans made primarily to
home buyers who make down payments of less than 20% of the home's purchase
price. Private mortgage insurance also facilitates the sale of such mortgage
loans in the secondary mortgage market, principally to Freddie Mac and Fannie
Mae. CMAC is restricted, both by state insurance laws and regulations and the
eligibility requirements of Fannie Mae and Freddie Mac, to providing insurance
on residential first mortgage loans only. CMAC currently offers two principal
types of private mortgage insurance coverage, primary and pool. At December 31,
1998, primary insurance represented 92.8% of CMAC's direct risk in force and
pool insurance represented 7.2% of CMAC's direct risk in force. The volume of
pool insurance written has increased significantly in 1997 and 1998, but is
expected to decline in 1999 and beyond due primarily to capital restrictions.
 
     CMAC has been engaged in the mortgage insurance business since 1977. The
Company acquired all of the outstanding common stock of CMAC in October 1992 in
order to facilitate the initial public offering of the Company's common stock.
In the offering, the Company's sole stockholder, Commonwealth Land Title
Insurance Company, then an indirect subsidiary of Reliance Group Holdings, Inc.,
sold all of the shares of common stock of the Company owned by it. As a result
of the offering, which was completed in November 1992, the Company became an
independent public company.
 
  Merger with Amerin
 
     By Agreement and Plan of Merger dated as of November 22, 1998, the Company
and Amerin Corporation agreed on a merger. The anticipated merger calls for
Amerin stockholders to receive 0.5333 shares of the Company's common stock in a
tax-free exchange for each share of Amerin common stock. The Company's
stockholders will continue to own their existing shares after the merger.
Completion of the merger is subject to approval by the stockholders of both
companies. The transaction is expected to close in May 1999 and to be accounted
for on a pooling of interests basis. Following the merger, Frank P. Filipps,
president and chief executive officer of the Company, will be chairman and chief
executive officer. Roy J. Kasmar, president and chief operating officer of
Amerin, will hold the same positions with the Company. Gerald L. Friedman,
chairman and chief executive officer of Amerin, will become chairman emeritus,
and Herbert Wender, chairman of the Company, will become chairman of the
executive committee of the board of directors. The new board will initially be
made up of the Company's board, Roy J. Kasmar and four individuals nominated by
Amerin. Based on the independent results for Amerin and the Company at December
31, 1998, and for the twelve-month period then ended, on a pro forma basis, the
combined company would have been the second largest mortgage insurance company
in the industry, measured by market share, with a combined market share of over
19%. The combined company would have had assets of $1.5 billion, common
stockholders' equity of $932 million and net income of $142 million.
 
  Primary Insurance
 
     Primary insurance provides mortgage default protection on individual loans
at a specified coverage percentage which is applied to the unpaid loan
principal, delinquent interest and certain expenses associated with the default
and subsequent foreclosure (collectively, the "claim amount"). CMAC's obligation
to an insured lender in respect of a claim is determined by applying the
appropriate coverage percentage to the claim amount. CMAC's "risk" on each
insured loan is the loan amount multiplied by the coverage percentage. Most of
CMAC's current business is written with 30% coverage on loans with a
loan-to-value ("LTV") ratio between 90.01% and 95% ("95s") and 25% coverage on
loans with an LTV ratio between 85.01% and 90%
 
                                        1
<PAGE>   3
 
("90s"). As of December 31, 1998, approximately 60% of CMAC's insurance in force
had such "deeper coverage". Deeper coverage refers to a higher percentage of
insurance coverage than previous historical levels on 90s and 95s. Beginning in
1995, both Fannie Mae and Freddie Mac began to require such coverage on 90s and
95s. Prior to 1995, the coverage requirements were 22% on 95s and 17% on 90s. In
January 1999, Fannie Mae announced a new program which allows for lower levels
of required mortgage insurance for certain low down payment loans approved
through its "Desktop Underwriter" automated underwriting system. The insurance
levels are similar to those required prior to 1995. In March 1999, Freddie Mac
announced a similar program for loans approved though its "Loan Prospector"
automated underwriting system. The Company does not believe that these
developments will adversely affect the demand for (or profitability of) mortgage
insurance. For more information on these developments, see "Freddie Mac and
Fannie Mae" on page 17. Under its master policy, CMAC has the option of paying
the entire claim amount and taking title to the mortgaged property, or paying
the coverage percentage in full satisfaction of its obligations under the
insurance written. Recently, CMAC has underwritten most of its primary insurance
by utilizing automated or streamlined underwriting methods.
 
  Pool Insurance
 
     Pool insurance differs from primary insurance in that the exposure on pool
insurance is not limited to a specific coverage percentage on each individual
loan. Because of this feature and the generally lower premium rates associated
with pool insurance, the rating agency capital requirements for the pool product
are more restrictive than the capital requirements for primary insurance. There
is an aggregate exposure limit ("stop loss") on a "pool" of loans which is
generally between 1% and 10% of the initial aggregate loan balance. Modified
pool insurance has a stop loss like pool insurance, but also has exposure limits
on each individual loan. The use of modified pool insurance is much more limited
than traditional pool insurance.
 
     CMAC offers pool insurance on a selected basis to various state housing
finance agencies on the collateral for their bond issues, as a credit
enhancement to mortgage loans included in mortgage-backed securities or in whole
loan sales, and in certain other specific situations. Since 1996, CMAC has
offered significant amounts of pool insurance on mortgage product sold to
Freddie Mac and Fannie Mae by CMAC's primary insurance customers ("GSE Pool").
This GSE Pool insurance has a very low stop loss, generally 1.0% to 1.5%, and
the insured pools contain loans with and without primary insurance. Premium
rates on this business are significantly lower than primary insurance rates and
the expected profitability on this business is lower than that of primary
insurance. The volume of such business increased significantly in 1997 and 1998
due to the strong demand for this product from CMAC's customers and due to the
increased size of the mortgage market. During 1998, CMAC had pool risk written
of $368.4 million relating specifically to GSE Pool business compared to $264.5
million in 1997. It is expected that CMAC will write less pool insurance in
1999. It is CMAC's current intention to reduce its net pool risk in force to no
more than 5% of CMAC's total risk in force. Net pool risk in force at December
31, 1998 represented 7.8% of total risk force. New premiums written for pool
insurance were $11.1 million in 1998, $4.8 million in 1997 and $2.1 million in
1996. The New York Insurance Department has issued a Circular Letter, which is
described more fully on page 16 of this Form 10-K, that could impact the terms
and conditions of future pool insurance transactions.
 
  Structured Transactions
 
     CMAC, from time to time, engages in structured transactions which may
include either primary insurance, pool insurance or some form of combination
thereof. A structured transaction generally involves insuring a large pool of
seasoned loans or issuing a commitment to insure new loan originations under
negotiated terms. Some structured transactions contain a risk-sharing component
under which the insured assumes a first-loss position or shares in losses in
some other manner. The amount of new premiums written in structured transactions
by CMAC were $4.7 million in 1998, $300,000 in 1997 and $400,000 in 1996.
 
  Revenue Sharing Products
 
     CMAC and the industry offer financial products to their customers that are
designed to allow the customer to participate in the risks and rewards of the
mortgage insurance business. One such product is
                                        2
<PAGE>   4
 
captive reinsurance, in which a mortgage lender sets up a mortgage reinsurance
company that assumes part of the risk associated with that lender's insured book
of business. In most cases, the risk assumed by the reinsurance company is an
excess layer of aggregate losses that would be penetrated only in a situation of
adverse loss development. CMAC had four captive reinsurance agreements in place
at December 31, 1998 and expects to enter into several new agreements in 1999.
Premiums ceded to captive reinsurance companies in 1998 were $1.5 million,
representing less than 1% of total premiums written. Another revenue sharing
product is a performance note ("SUPER Note"), which allows a mortgage lender to
invest a portion of capital needed to support its insured mortgage insurance
book and to receive a return on investment that approximates the return that
CMAC achieves on that same book of business. At December 31, 1998, CMAC had $1.9
million of outstanding SUPER Notes. The aggregate amount of captive reinsurance
and SUPER Note business is not expected to have a material impact on CMAC's
balance sheet or financial results in 1999. Clarification of the Letter, which
is described more fully on page 16 of this Form 10-K, could impact the terms and
conditions of future revenue sharing transactions.
 
CUSTOMERS
 
     Mortgage originators such as mortgage bankers, mortgage brokers, commercial
banks and savings institutions are CMAC's principal customers, although mortgage
borrowers generally bear the cost of primary insurance coverage. CMAC does, on a
limited basis, offer lender-paid mortgage insurance whereby mortgage insurance
premiums are charged to the mortgage lender or loan servicer. On the lender-paid
product, the interest rate to the borrower is usually higher to compensate for
the mortgage insurance premium that the lender is paying. In 1998, approximately
2.8% of CMAC's primary insurance was done on a lender-paid basis, however this
percentage could increase in 1999 and beyond if borrowers become less sensitive
to the stated interest rate and instead focus more on total monthly costs.
 
     To obtain primary insurance from CMAC, a mortgage lender must first apply
for and receive a master policy from CMAC. CMAC's approval of a lender as a
master policyholder is based, among other factors, upon an evaluation of the
lender's financial position and its management's demonstrated adherence to sound
loan origination practices. CMAC's quality control function then monitors the
master policyholder.
 
     The number of primary individual policies in force was 491,836 at December
31, 1998, 441,605 at December 31, 1997 and 382,243 at December 31, 1996.
 
     CMAC's top 10 customers were responsible for 40.3% of new primary risk
written in 1998 compared to 28.4% in 1997 and 21.8% in 1996. The largest single
customer of CMAC, (including branches and affiliates of such customer), measured
by risk written, accounted for 14.4% of new primary risk written during 1998
compared to 4.9% in 1997 and 4.0% in 1996. In 1998, the Company's largest single
customer was Norwest Mortgage, Inc.
 
SALES, MARKETING AND COMPETITION
 
  Sales and Marketing
 
     CMAC employs a field sales force of approximately 100 persons, organized
into three divisions, providing local sales representation throughout the United
States. During 1997, CMAC reorganized by reducing the number of divisions from
six to three and introducing the new position of Area Sales Manager in order to
provide more direct supervision of the field sales force. Each of the three
divisions is supervised by a Divisional Sales Manager who is directly
responsible for several Area Sales Managers. The Area Sales Managers are
responsible for managing a small sales force in different areas within the
division. An increase to five regions within this structure is anticipated in
1999. CMAC sales personnel are compensated by salary, commissions on new
insurance written and a production incentive based on the achievement of various
goals. During 1998, these goals were related to volume, market share, change in
market share and business quality as measured by CMAC's mortgage scoring model
and this is generally expected to continue in 1999. In early 1997, CMAC expanded
its effort to serve larger national accounts, which have become a more integral
part of the mortgage insurance market due to consolidation in the mortgage
lending industry. Two dedicated national account positions were created and a
more focused effort to support national accounts was implemented. CMAC
 
                                        3
<PAGE>   5
 
added to this effort in 1998 with two additional dedicated positions and expects
the national account area to be particularly important in 1999 and beyond.
 
  Competition
 
     CMAC and other private mortgage insurers compete directly with various
federal government agencies, principally the Federal Housing Administration
("FHA"). In addition to competition from federal agencies, CMAC and other
private mortgage insurers face competition from state-supported mortgage
insurance funds. The private mortgage insurance industry consists of CMAC and
seven other active mortgage insurance companies. During 1998, CMAC was the fifth
largest private mortgage insurer, measured by market share, and had, according
to industry data, a market share of new primary mortgage insurance written of
11.5%.
 
UNDERWRITING PRACTICES
 
     CMAC considers effective risk management to be critical to its long-term
financial stability. Market analysis, prudent underwriting, the use of automated
risk evaluation models, quality control and customer service are all important
elements of CMAC's risk management process.
 
  Underwriting Personnel
 
     In addition to a centralized National Underwriting department in the home
office, each of CMAC's service divisions has a Divisional Service Manager
responsible for evaluating risk and managing all underwriting field staff in the
region. CMAC employs an underwriting and support staff of approximately 110 who
are located in CMAC's 25 service centers. Additionally, CMAC has two agency
operations in place.
 
  Underwriting Process
 
     CMAC has generally accepted applications for primary insurance (other than
in connection with structured transactions) under three basic programs: the
traditional fully documented program, a limited documentation program and the
delegated underwriting program. Programs that involve less than fully documented
file submissions have become more prevalent in recent years. In order to meet
this demand, in the fourth quarter of 1996, CMAC introduced to the marketplace
the process referred to as "ExpressTrac(sm)". A lender utilizing ExpressTrac can
submit loans to CMAC for insurance with abbreviated levels of documentation
based on the type of loan being submitted for insurance. During 1998, 61% of the
commitments issued for primary insurance were received by CMAC under the
ExpressTrac program. In the ExpressTrac Program, CMAC has agreed to underwrite
certain loans with less documentation by relying upon a scoring model created by
CMAC during 1996 and referred to as "Prophet Score(sm)" (described below). The
ExpressTrac program also allows for a reduction in standard premium rates (4
basis points) for loans having FICO credit scores (described below) of 680 or
greater although there is no assurance that this discount will continue in the
future. During 1998, 54% of the commitments issued by CMAC for primary insurance
qualified for this discounted rate.
 
  Delegated Underwriting
 
     CMAC has a delegated underwriting program with certain customers. CMAC's
delegated underwriting program, which was implemented in 1989, currently
involves only lenders that are approved by CMAC's risk management department.
Delegated underwriting programs allow the lender's underwriters to commit CMAC
to insure loans based on agreed upon underwriting guidelines. CMAC routinely
audits loans submitted under these programs. As of December 31, 1998,
approximately 41% of the primary loans on CMAC's books were originated on a
delegated basis and during 1998, 60% of the primary loans insured by CMAC were
originated on a delegated basis. This compares with 33% of the primary loans on
CMAC's books at December 31, 1997 and 55% of the primary loans originated during
1997.
 
                                        4
<PAGE>   6
 
  Automated Underwriting
 
     In 1994, CMAC installed an automated underwriting system which uses
artificial intelligence technology to assist CMAC's underwriting staff in the
processing of loan files. The system allows the underwriter to eliminate the
rudimentary underwriting steps and to focus on key aspects of the loan file,
with the ultimate goal of increasing underwriting efficiency while maintaining
the same level of risk exposure. During 1995, the system was fully integrated
into the CMAC underwriting process and improved efficiency was realized. In
1996, CMAC further enhanced the automated underwriting system by adding its
Prophet Score model to the automated underwriting system's decision making
process. Direct connections between the CMAC network and Fannie Mae's Desktop
Underwriter and Freddie Mac's Loan Prospector systems were implemented in
January 1998.
 
  Mortgage Scoring Models
 
     During the last few years, the use of scoring mechanisms to predict loan
performance has become prevalent in the marketplace, especially with Fannie Mae
and Freddie Mac's advocacy of the use of credit scores in the mortgage loan
underwriting process. The use of credit scores was pioneered by Fair Isaac and
Company and became popular in the mid-1980s. The FICO model calculates a score
based on a borrower's credit history. This credit score based "scorecard" is
used to predict the future performance of a loan over a one or two year time
horizon. The higher the credit score the lower the likelihood that a borrower
will default on a loan. CMAC's Prophet Score begins with a FICO score then adds
specific additional data regarding the borrower, the loan and the property. CMAC
believes that it is this additional mortgage data that expands the integrity of
CMAC's Prophet Score over the entire life of the loan. In addition to the
Prophet Score, CMAC's housing analysts regularly review major metropolitan areas
to assess the impact that key indicators such as housing permits, employment
trends, and median home sale prices have on local lending. The healthier the
real estate market, the lower the risk. CMAC refers to this score as a GEOScore.
Beginning in October 1996, the Prophet Score and GEOScore appeared on each
insurance commitment that CMAC issued. In 1998, the Prophet and GEOScores were
combined into a more powerful "Composite Prophet Score" that aggregates the
credit and economic factors into one decision tool.
 
  Alternative Products
 
     An increasingly popular form of mortgage lending is in the area of
non-conforming loans. Two subsets of this category in which CMAC has recently
become involved are Alternative A loans and A minus loans. Alternative A
borrowers have an equal or better credit profile than CMAC's typical insured
borrowers, but these loans are underwritten with reduced documentation and
verification of information. CMAC typically charges a higher premium rate for
this business due to the reduced documentation, but does not consider this
business to be significantly more risky than its normal primary business. The A
minus loan programs typically have non-traditional credit standards which are
less stringent than standard credit guidelines. This market was created as an
avenue to homeownership for borrowers who had not properly maintained their
credit profile over time. CMAC receives a significantly higher premium for
insuring this product that is commensurate with the additional default risk and
is often a variable rate based on the Prophet Score. CMAC intends to limit its
participation in the non-conforming market to Alternative A and A minus loans
rather than "B" or "C" (lower credit) loans and to limit the business insured to
specific targeted lenders with proven good results and servicing experience in
this area. Alternative products made up less than 8% of CMAC's primary insurance
written during 1998, and most of this non-conforming product was categorized as
Alternative A business.
 
  Contract Underwriting
 
     CMAC utilizes its underwriting skills to provide an outsource contract
underwriting service to its customers. For a fee, CMAC underwrites fully
documented underwriting files for secondary market compliance, while at the same
time assessing the file for mortgage insurance, if applicable. The automated
underwriting service introduced in the latter part of 1997 has become a major
part of CMAC's contract underwriting service. This service offers customers
access to Fannie Mae's Desktop Underwriter and Freddie Mac's Loan Prospector
automated underwriting systems. Contract underwriting continues to be a popular
                                        5
<PAGE>   7
 
service to our customers. During 1998, loans underwritten via contract
underwriting accounted for 33% of applications, 29% of commitments for insurance
and 24% of insurance certificates issued by CMAC. Record mortgage origination
volume during 1998 resulted in increased costs which were offset somewhat by
higher fees. CMAC gives recourse to its customers on loans it underwrites for
compliance. If the loan does not meet agreed upon guidelines and is not salable
in the secondary market for that reason, CMAC agrees to remedy the situation
either by placing mortgage insurance coverage on the loan or by purchasing the
loan. During 1998, CMAC processed requests for remedies on less than 1% of the
contract loans underwritten and sold a number of loans previously acquired as
part of the remedy process. Providing these remedies means CMAC assumes some
credit risk and interest rate risk if an error is found during the limited
remedy period in our agreements. Rising mortgage interest rates or an economic
downturn may expose CMAC to higher losses. During 1998, the financial impact of
these remedies was insignificant although there is no assurance that such
results will continue in 1999 and beyond.
 
RATINGS
 
     CMAC, along with other active private mortgage insurers, has its
claims-paying ability and financial strength rated by Standard & Poor's ("S&P"),
Moody's Investors Service, Inc. ("Moody's") and Duff & Phelps Credit Rating
Company ("DCR"). These ratings are an indication to a mortgage insurer's
customers of the insurer's present financial strength and its capacity to honor
its future claims payment obligations. Ratings are generally considered critical
to an insurer's ability to compete for new insurance business. Currently, CMAC
is rated "AA" by S&P and DCR, and "Aa3" by Moody's. CMAC has received assurance
from Moody's, S&P and DCR that the merged company will maintain a rating similar
to the current rating upon completion of the merger
 
REINSURANCE
 
     CMAC reinsures all direct insurance in force under an excess of loss
reinsurance program which CMAC considers to be an effective catastrophic
reinsurance coverage. Under this program, the reinsurer is responsible for 100%
of CMAC's covered losses in excess of CMAC's retention. CMAC's annual retention
is determined by a formula which contains variable components. The estimated
1999 retention is approximately $480 million of loss which represents 150% of
expected premiums earned. The reinsurer's aggregate annual limit of liability is
also determined by a formula with variable components and is currently estimated
to be $92.5 million. In addition, for 1999, a limit has been set on the amount
of annual pool insurance losses that can be counted in the reinsurance
recoverable calculation. For 1999, this limit is $90 million. If the reinsurer
decides not to renew the reinsurance arrangement and is not replaced by CMAC,
the reinsurer must provide six years of runoff coverage. There is an overall
aggregate limit of liability applicable to any runoff period equal to four times
the annual limit in effect for the calendar year of such nonrenewal. For 1999,
this aggregate limit is estimated to be $370 million. The excess of loss
reinsurance program also provides restrictions and limitations on the payment of
dividends by CMAC, investments, mergers or acquisitions involving other private
mortgage insurance companies and reinsurance of exposure retained by CMAC.
 
     In addition, CMAC has entered into a variable quota-share ("VQS") treaty
for primary risk in the 1994 to 1997 origination years and a portion of the pool
risk written in 1997. In this treaty, quota-share loss relief is provided at
varying levels ranging from 7.5% to 15.0% based upon the loss ratio on the
reinsured book. The higher CMAC's loss ratio, the greater the potential
reinsurance relief which protects CMAC in adverse loss situations. A ceding
commission is paid by the reinsurer to CMAC and the agreement is noncancelable
for ten years by either party. As of December 31, 1998, the risk in force
covered by the VQS treaty was approximately $6.1 billion, or approximately 53%
of CMAC's primary risk in force and $84 million, or approximately 10% of CMAC's
pool risk in force. It is CMAC's present intention not to reinsure any
additional business pursuant to the VQS treaty for the 1999 origination year,
although the ultimate decision on reinsurance could be impacted by business
volume, capital adequacy and other factors.

DEFAULTS AND CLAIMS
 
  Defaults
 
     The default and claim cycle on loans which have private mortgage insurance
begins with the insurer's receipt from the lender of notification of a default
on an insured loan. The master policy requires lenders to notify CMAC of an
uncured default on a mortgage loan within 75 days (45 days for an uncured
default in the first year of the loan), although many lenders do so earlier. The
incidence of default is affected by a variety of factors, including change in
borrower income, unemployment, divorce and illness, the level of interest rates
and general borrower creditworthiness. Defaults that are not cured result in
claims to CMAC. Borrowers may cure defaults by making all delinquent loan
payments or by selling the property and satisfying all amounts due under the
mortgage.
 
     The following table shows the number of primary and pool loans insured,
related loans in default and the percentage of loans in default (default rate)

     As of December 31, 1998, default rates for CMAC's two largest states
measured by risk in force were 2.6% for California and 3.6% for Florida compared
to 3.6% for California and 3.8% for Florida at December 31, 1997. The relatively
high default rate in Florida is due primarily to the increased "affordable
housing" business done in Florida since 1994 and the relatively high default
development on such business.
 
  Claims
 
     The likelihood that a claim will result from a default and the amount of
such claim depend principally on the borrower's equity at the time of default
and the borrower's (or the lender's) ability to sell the home for an
 
                                        7
<PAGE>   9
 
amount sufficient to satisfy all amounts due under the mortgage, as well as the
effectiveness of loss mitigation efforts. Claims are also affected by local
housing prices, interest rates, unemployment levels and the housing supply.
 
     Claim activity is not evenly spread through the coverage period of a book
of business. Relatively few claims are received during the first two years
following issuance of the policy. This is followed by a period of rising claims
which, based on industry experience, has historically reached its highest level
in the third through fifth years after the year of loan origination. Thereafter,
the number of claims received has historically declined at a gradual rate,
although the rate of decline can be affected by conditions in the economy.
Approximately 58% of CMAC's primary risk in force and almost all of CMAC's pool
risk in force at December 31, 1998 had not yet reached its anticipated highest
claim frequency years. CMAC's cumulative claim incidence on insurance written,
determined four years after policy issuance, was 1.5% for insurance written in
1992, 1.5% for insurance written in 1993, and 2.0% for insurance written in
1994. Certain "affordable housing" loans insured in 1994 and 1995 have
experienced higher than normal early default and claim rates, although these
results are not anticipated to have a material effect on the Company's financial
statements due to the relatively small component of such loans in CMAC's book.
Many of the reasons for these early defaults have been addressed in the
underwriting of such loans since 1996.
 
LOSS MITIGATION
 
     CMAC's loan workout staff consists of 20 employees, including 13 full-time
loan workout specialists who proactively intervene in the default process,
working with borrowers to reduce the frequency and severity of foreclosure
losses. Once a notice of default is received, CMAC scores the default using a
proprietary model that predicts the likelihood that the default will become a
claim. Using this model, the loan workout specialists prioritize cases for
proactive intervention to counsel and assist borrowers. Loss mitigation
techniques include pre-foreclosure sales, extensions of credit to borrowers to
reinstate insured loans, loan modifications and deficiency settlements. CMAC
considers its loss mitigation efforts to be an effective way to reduce claim
payments.
 
HOMEOWNERSHIP COUNSELING
 
     In 1995, CMAC established a Homeownership Counseling Center (the "Center")
to work with borrowers receiving insured loans under Community Homebuyer, 97%
loan-to-value ("97s") or other "affordable housing" programs. CMAC considers
this counseling to be very important to the future success of those particular
borrowers with regard to sustaining their mortgage payments. In addition, the
Center counsels such borrowers early in the default process in an attempt to
help cure the loan and assist the borrower in meeting their mortgage obligation.
 
LOSS RESERVES
 
     CMAC establishes reserves to provide for the estimated costs of settling
claims in respect of loans reported to be in default and loans that are in
default which have not yet been reported to CMAC. Consistent with generally
accepted accounting principles and industry accounting practices, CMAC does not
establish loss reserves for future claims on insured loans which are not
currently in default. In determining the liability for unpaid losses related to
reported outstanding defaults, CMAC establishes loss reserves on a case-by-case
basis. The amount reserved for any particular loan is dependent upon the status
of the loan as reported by the servicer of the insured loan, as well as the
economic condition and estimated foreclosure period in the area in which the
default exists. As the default progresses closer to foreclosure, the amount of
loss reserve for that particular loan will be increased, in stages, to
approximately 100% of CMAC's exposure. CMAC also reserves for defaults that have
occurred but have not been reported using historical information on defaults not
reported on a timely basis by lending institutions. The estimates are
continually reviewed and adjustments are made to the liability as necessary.

ANALYSIS OF PRIMARY RISK IN FORCE
 
     CMAC's business strategy has been to disperse risk as widely as possible.
CMAC analyzes its portfolio in a number of ways to identify any concentrations
or imbalances in risk dispersion. CMAC believes the quality of its insurance
portfolio is affected significantly by:
 
     - the geographic dispersion of the properties securing the insured loans;
 
     - the quality of loan originations;
 
     - the types of loans insured (including LTV ratio, purpose of the loan,
       type of loan instrument and type of underlying property securing the
       loan); and
 
     - the age of the loans insured.
 
  Geographic Dispersion
 
     The following tables reflect the percentage of direct primary risk in force
on CMAC's book of business (by location of property) for the top ten states and
top 15 metropolitan statistical areas ("MSAs") as of December 31, 1998 and 1997:

  Lender and Product Characteristics
 
     While geographic dispersion is an important component of overall risk
dispersion and it has been a strategy of the Company to reduce its exposure in
the top 10 states and top 15 MSAs, the Company believes the quality of the risk
in force should be considered in conjunction with other elements of risk
dispersion, such as product distribution, as well as CMAC's risk management and
underwriting practices.

(1) Includes traditional and modified pool insurance.
 
(2) Refers to loans where payment adjustments are the same as mortgage interest
    rate adjustments.
 
(3) Loans with potential negative amortization will not have increasing
    principal balances unless interest rates increase as contrasted with
    scheduled negative amortization where an increase in loan balance will occur
    even if interest rates do not change.
 
     One of the most important determinants of claim incidence is the relative
amount of borrower's equity in the home, or down payment. The expectation of
claim incidence on 95s is approximately two times the expected claim incidence
on 90s. CMAC believes that the higher premium rates it charges on 95s adequately
reflect the additional risk on these loans. The industry and CMAC have been
insuring 97s since 1995. These loans are expected to have a higher claim
incidence than 95s; however, with proper counseling efforts and by limiting
insurance on these loans to sensible affordable housing programs, it is CMAC's
belief that the claim incidence should not be materially (more than one and
one-half times) worse than on 95s, although this cannot be certain. Early
defaults on 97s as compared to other loans have confirmed CMAC's expectations,
although the eventual performance of these loans cannot yet be accurately
projected. Premium rates on 97s are higher than on 95s to compensate for the
additional risk and the higher expected frequency and severity of claims. The
amount of 97s insured in 1998 and 1997 was between 3% and 4% of the total loans
insured each year and the percentage of primary risk in force on insured 97s
went from 2.6% at the end of 1996 to 3.5% at the end of 1998. The percentage of
97s written in 1999 should approximate the 1998 and 1997 figures.
 
     In recent years, CMAC has increased its insurance on mortgages identified
by its customers as "affordable housing" loans. These loans are typically made
to low- and moderate-income borrowers in conjunction with special programs
developed by state or local housing agencies, Fannie Mae or Freddie Mac. Such
programs usually include 95s and 97s and may require certain underwriting
guidelines to be liberalized in order to achieve their objectives. CMAC's
participation in these programs is dependent upon acceptable borrower
counseling. Early default experience on these programs has been worse than
non-"affordable housing" loans, however CMAC does not believe the ultimate
claims will materially affect its financial results due to the relatively small
amount of such business combined with higher premium rates and risk-sharing
elements.
 
     CMAC's claim frequency on insured ARMs has been higher than on all other
loan types. The Company believes that the risk on ARM loans is greater than on
fixed rate loans due to possible monthly payment increases if interest rates
rise.
 
                                       11

     The Company believes that 15-year mortgages present a lower level of risk
than 30-year mortgages, primarily as a result of the faster amortization and the
more rapid accumulation of borrower equity in the property. Premium rates for
15-year mortgages are lower to reflect the lower risk.
 
     The Company believes that the risk of claim is also affected by the type of
property securing the insured loan. In the Company's opinion, loans on
single-family detached housing are subject to less risk of claim incidence than
loans on other types of properties. Conversely, loans on attached housing types,
particularly condominiums and cooperatives, are generally considered by the
Company to be a higher risk, due to the higher density of such properties and
because a detached unit is the preferred housing type in most areas. CMAC's more
stringent underwriting guidelines on condominiums and cooperatives reflect this
higher expected risk.
 
     The Company believes that the risk of claim on relocation loans and loans
originated by credit unions is extremely low and offers lower premium rates on
such loans to compensate for the lower risk.
 
     The Company believes that loans on non-owner occupied homes purchased for
investment purposes represent a substantially higher risk of claim incidence,
and are subject to greater value declines than loans on either primary or second
homes. CMAC underwrites loans on non-owner occupied homes more stringently, and
sometimes requires that the investor indemnify CMAC directly for any loss
suffered by CMAC.
 
     CMAC also charges a significantly higher premium rate than the rate charged
for insuring loans on owner occupied homes.
 
     The Company believes that higher priced properties experience wider
fluctuations in value than moderately priced residences and that the income of
many people who buy higher priced homes is less stable than that of people with
moderate incomes. Underwriting guidelines for such higher priced properties
reflect this concern.
 
INVESTMENT PORTFOLIO
 
     The Company's income from its investment portfolio is one of the Company's
primary sources of cash flow to support its operations and claim payments.
 
     The Company follows an investment policy which, at a minimum, requires:
 
     - 95% of its investment portfolio to consist of cash equivalents and debt
       securities (including redeemable preferred stocks) which, at the date of
       purchase, were rated investment grade by a nationally recognized rating
       agency (e.g., "BBB" or better by S&P); and
 
     - at least 50% of its investment portfolio (together with cash assets) to
       consist of cash, cash equivalents and debt securities (including
       redeemable preferred stocks) which, at the date of purchase, were rated
       the highest investment grade by a nationally recognized rating agency
       (e.g., "AAA" by S&P).
 
In December 1997, the Company's investment policy was amended to permit
investment in equity securities (which includes convertible debt and convertible
preferred stock). This equity component is not permitted to exceed 20% of the
total investment portfolio and the Company began investing in equity securities
in 1998. The 95% investment-grade requirement was not changed. In addition, all
investments purchased in 1998 were classified as available for sale in contrast
to primarily held to maturity, as was typical during prior years. However, the
portfolio still contains mostly held to maturity investments.
 
     At December 31, 1998, the Company's investment portfolio had a carrying
value of $736.3 million and a market value of $743.7 million, including $18.6
million of short-term investments. At December 31, 1998, the Company's
investment portfolio did not include any real estate or mortgage loans. The
portfolio included 10 privately placed, investment-grade securities with an
aggregate carrying value of $6.4 million. At December 31, 1998, 96.3% of the
Company's investment portfolio (which excludes cash) consisted of cash
equivalents and debt securities (including redeemable preferred stocks) rated
investment grade.

     The Company's investment policies and strategies are subject to change
depending upon regulatory, economic and market conditions and the then existing
or anticipated financial condition and operating requirements, including the tax
position, of the Company.

REGULATION
 
  Direct Regulation
 
     State Regulation
 
     The Company and its insurance subsidiaries are subject to comprehensive,
detailed regulation principally designed for the protection of policyholders,
rather than for the benefit of investors, by the insurance departments in the
various states where the Company and its insurance subsidiaries are licensed to
transact business. Insurance laws vary from state to state, but generally grant
broad supervisory powers to agencies or officials to examine insurance companies
and enforce rules or exercise discretion affecting almost every significant
aspect of the insurance business.
 
     Insurance regulations relate, among other things to:
 
     - the licensing of companies to transact business;
 
     - claims handling;
 
     - reinsurance requirements;
 
     - premium rates and policy forms offered to customers;
 
     - financial statements;
 
     - periodic reporting;
 
     - permissible investments; and
 
     - adherence to financial standards relating to surplus, dividends and other
       criteria of solvency intended to assure the satisfaction of obligations
       to policyholders.
 
                                       14
<PAGE>   16
 
     Mortgage insurers are generally restricted to writing residential mortgage
guaranty insurance business only. This restriction essentially prohibits CMAC
from using its capital resources in support of other types of insurance or
non-insurance business. The non-insurance businesses of the Company, which
consist of mortgage insurance related services, are not generally subject to
regulation under state insurance laws.
 
     Insurance Holding Company Regulation.  All states have enacted legislation
that requires each insurance company in an insurance holding company system to
register with the insurance regulatory authority of its state of domicile and to
furnish to such regulator financial and other information concerning the
operations of companies within the holding company system that may materially
affect the operations, management or financial condition of insurers within the
system.
 
     Because the Company is an insurance holding company and CMAC is a
Pennsylvania insurance company, the Pennsylvania insurance laws regulate, among
other things, certain transactions in the Company's common stock and certain
transactions between CMAC, the company's other insurance subsidiaries and their
parent or affiliates. Specifically, no person may, directly or indirectly, offer
to acquire or acquire "control" of the Company, CMAC or the other insurance
subsidiaries unless such person files a statement and other documents with the
Pennsylvania Commissioner of Insurance and obtains the Commissioner's prior
approval. The Commissioner may hold a public hearing on the matter. "Control" is
presumed to exist if 10% or more of CMAC or another of the Company's insurance
subsidiaries' voting securities is owned or controlled, directly or indirectly,
by a person, although the Pennsylvania Commissioner of Insurance may find that
"control" in fact does or does not exist where a person owns or controls a
lesser amount of securities. In addition, material transactions between CMAC and
the Company's other insurance subsidiaries and their parent or affiliates are
subject to certain conditions, including that they be "fair and reasonable."
These restrictions generally apply to all persons controlling or under common
control with CMAC or the Company's other insurance subsidiaries. Certain
transactions between the Company's insurance subsidiaries and their parent or
affiliates may not be entered into unless the Pennsylvania Commissioner of
Insurance is given 30 days prior notification and does not disapprove the
transaction during such 30-day period.
 
     Dividends.  The insurance laws of Pennsylvania establish a test limiting
the maximum amount of dividends which may be paid without prior approval by the
Pennsylvania Insurance Commissioner. Under such test, CMAC may pay dividends
during any 12-month period in an amount equal to the greater of:
 
     - 10% of the preceding year-end statutory policyholders' surplus; or
 
     - the preceding year's statutory net income.
 
In accordance with such restrictions, $105.3 million would be available for
dividends in 1999. However, an amendment to the Pennsylvania statute, effective
in 1994, requires that dividends and other distributions be paid out of an
insurer's unassigned surplus. Because of the unique nature of the method of
accounting for contingency reserves, CMAC has negative unassigned surplus. Thus,
prior approval by the Pennsylvania Insurance Commissioner is required for CMAC
to pay dividends or make other distributions so long as CMAC has negative
unassigned surplus. The Pennsylvania Insurance Commissioner has approved all
distributions by CMAC since the passage of this amendment, and management has
every expectation that the Insurance Department will continue to approve such
distributions in the future, provided that the financial condition of CMAC does
not materially change. The State of California has a statute requiring mortgage
insurers to pay dividends or make other distributions out of unassigned surplus.
CMAC and the California Department of Insurance have reached an understanding
under which CMAC will be able to pay dividends or make other distributions to
the Company provided that the financial condition of CMAC does not materially
change.
 
     Risk to Capital.  A number of states and Freddie Mac limit a private
mortgage insurer's risk in force to 25 times the total of the insurer's
policyholders' surplus plus the statutory contingency reserve, commonly known as
the "risk-to-capital" requirement. As of December 31, 1998, CMAC's
risk-to-capital ratio was 18.1 to 1, compared to 18.3 to 1 in 1997.
 
                                       15
<PAGE>   17
 
     Reserves.  For statutory reporting, CMAC is annually required to provide
for additions to the contingency reserve in an amount equal to 50% of earned
premiums. Such amounts cannot be withdrawn for a period of 10 years except under
certain circumstances. The contingency reserve, designed to be a reserve against
catastrophic losses, essentially restricts dividends and other distributions by
CMAC. Prior to 1995, CMAC had included the contingency reserve as a component of
policyholders' surplus. The Pennsylvania Insurance Department has determined
that the contingency reserve should be classified as a liability in the
statutory balance sheet rather than as a component of policyholders' surplus. In
response to this determination, commencing in January 1995, CMAC began
classifying the contingency reserve as a liability. At December 31, 1998, CMAC
had policyholders' surplus of $149.3 million and a contingency reserve of $467.9
million.
 
     Premium Rates and Policy Forms.  CMAC's premium rates and policy forms are
subject to regulation in every state in which it is licensed to transact
business in order to protect policyholders against the adverse effects of
excessive, inadequate or unfairly discriminatory rates and to encourage
competition in the insurance marketplace. In most states, premium rates and
policy forms must be filed prior to their use. In some states, such rates and
forms must also be approved prior to use. Changes in premium rates are subject
to justification, generally on the basis of the insurer's loss experience,
expenses and future trend analysis. The general default experience in the
mortgage insurance industry may also be considered.
 
     Reinsurance.  Certain restrictions apply under the laws of several states
to any licensed company ceding business to an unlicensed reinsurer. Under such
laws, if a reinsurer is not admitted or approved in such states, the company
ceding business to the reinsurer cannot take credit in its statutory financial
statements for the risk ceded to such reinsurer absent compliance with certain
reinsurance security requirements. In addition, several states also have special
restrictions on mortgage guaranty insurance. Also, several states limit the
amount of risk a mortgage insurer may retain with respect to coverage on an
insured loan to 25% of the insured's claim amount. Coverage in excess of 25%
(i.e., deep coverage) must be reinsured.
 
     Examination.  The Company's insurance subsidiaries are subject to
examination of their affairs by the insurance departments of each of the states
in which they are licensed to transact business.
 
     New York Circular Letter.  The New York Insurance Department (the
"Department") issued Circular Letter No. 2 dated February 1, 1999 (the "Letter")
which discusses the Department's position concerning various transactions
between mortgage guaranty insurance companies licensed in New York and mortgage
lenders. The Letter confirms that captive reinsurance transactions are
permissible if they "constitute a legitimate transfer of risk" and "are fair and
equitable to the parties." The Department is currently in the process of
developing guidelines for determining which captives are, in fact, permissible.
In addition, the Letter states that "supernotes/performance notes," "dollar
pool" insurance, and "un-captive captives" violate New York law. The Company is
in the process of seeking further guidance with regard to the Letter and
revising its revenue-sharing products as appropriate to ensure compliance with
the Letter's requirements.
 
  Federal Regulation
 
     RESPA.  The origination or refinance of a federally regulated mortgage loan
is a settlement service, and therefore subject to the Real Estate Settlement
Practices Act of 1974, and the regulations promulgated thereunder (collectively,
"RESPA"). In December 1992, regulations were issued which made clear that
mortgage insurance is also a settlement service, and therefore, that mortgage
insurers are subject to the provisions of Section 8(a) of RESPA, which generally
prohibits persons from accepting anything of value for referring real estate
settlement services to any provider of such services. Although many states
prohibit mortgage insurers from giving rebates, RESPA has been interpreted to
cover many non-fee services as well. HUD's interest in pursuing violations of
RESPA has increased awareness of both mortgage insurers and their customers of
the possible sanctions of this law.
 
     HMDA.  Most originators of mortgage loans are required to collect and
report data relating to a mortgage loan applicant's race, nationality, gender,
marital status and census tract to HUD or the Federal Reserve under the Home
Mortgage Disclosure Act of 1975 ("HMDA"). The purpose of HMDA is to detect
possible discrimination in home lending and, through disclosure, to discourage
such discrimination. Mortgage
                                       16
<PAGE>   18
 
insurers are not required pursuant to any law or regulation to report HMDA data,
although under the laws of several states, mortgage insurers are currently
prohibited from discriminating on the basis of certain classifications.
 
     The active mortgage insurers, through their trade association, Mortgage
Insurance Companies of America ("MICA"), entered into an agreement with the
Federal Financial Institutions Examinations Council ("FFIEC") to report the same
data on loans submitted for insurance as is required for most mortgage lenders
under HMDA. The first report of HMDA-type data was collected by MICA from its
members for the fourth quarter of 1993 and reported to the FFIEC in the first
quarter of 1994. Subsequent reports of HMDA-type data for the mortgage insurance
industry were submitted by MICA to the FFIEC in March 1995, 1996 and 1997.
Management is not aware of any pending or expected actions by governmental
agencies in response to the reports submitted by MICA to the FFIEC.
 
     Mortgage Insurance Cancellation.  The Homeowners Protection Act of 1998
(the "Act") was signed into law on July 29, 1998. The legislation imposes
certain cancellation and termination requirements for borrower-paid private
mortgage insurance and requires certain disclosures to borrowers regarding their
rights under the law. Specifically, the Act provides that private mortgage
insurance on most loans originated on or after July 29, 1999 may be canceled at
the request of the borrower once the LTV reaches 80%, provided that certain
conditions are satisfied. Private mortgage insurance must be canceled
automatically once the LTV reaches 78% or, if the loan is not current on that
date, on the date that the loan becomes current. The Act establishes special
rules for the termination of private mortgage insurance in connection with loans
that are "high risk". The Act does not define "high risk" loans but leaves that
determination to Fannie Mae and Freddie Mac for loans up to the conforming loan
limit and to the mortgagee for any other loan. For "high risk" conforming loans,
it appears from the Act that Fannie Mae and Freddie Mac can determine how long
private mortgage insurance must remain in effect. For "high risk" loans above
the conforming loan limit, private mortgage insurance must be terminated on the
date that the LTV is first scheduled to reach 77%. In no case, however, may
private mortgage insurance be required beyond the midpoint of the amortization
period of the loan if the mortgagor is current on the payments required by the
terms of the mortgage. The Company does not believe that the Act will have a
material effect on its financial condition or results of operations.
 
  Other Direct Regulation
 
     Freddie Mac and Fannie Mae
 
     As the most significant purchasers and sellers of conventional mortgage
loans and beneficiaries of private mortgage insurance, Freddie Mac and Fannie
Mae impose requirements on private mortgage insurers in order for such insurers
to be eligible to insure loans sold to such agencies. Freddie Mac's current
eligibility requirements impose limitations on the type of risk insured,
standards for the geographic and customer diversification of risk, procedures
for claims handling, acceptable underwriting practices and financial
requirements which generally mirror state insurance regulatory requirements.
These requirements are subject to change from time to time. Fannie Mae also has
eligibility requirements, although such requirements are not published. CMAC is
an approved mortgage insurer for both Freddie Mac and Fannie Mae.
 
     In 1995, Freddie Mac and Fannie Mae began to require deeper coverage on
certain loans with LTV ratios greater than 85%. The Company believes that this
deeper coverage does not have a material effect on its financial results,
although premiums earned and the provision for losses increased and the
risk-to-capital ratio is higher as a result of the increase in risk.
 
     In 1995, CMAC issued a new Master Policy which applied to all business
written after June 1, 1995. Changes in the terms included a broader scope of
coverage for certain environmental and bankruptcy related claims, and somewhat
more limited rights to reject claim payments, neither of which the Company
believes will have a material adverse effect on CMAC's operations or financial
results. The new Master Policy was approved by Fannie Mae and Freddie Mac, as
well as by all states which require approval of policy forms.
 
     In January 1999, Fannie Mae announced a new program which allows for lower
levels of required mortgage insurance coverage for low down payment 30-year
fixed rate loans approved through its Desktop Underwriter automated underwriting
system. The insurance levels are similar to those required prior to 1995.
 
                                       17
<PAGE>   19
 
In March 1999, Freddie Mac announced a similar program for loans approved
through its Loan Prospector underwriting system. Fannie Mae will replace some of
the coverage with a layer of investor mortgage insurance coverage provided by at
least two mortgage insurers, one of which will be CMAC. Fannie Mae also
announced that it intends to purchase additional insurance for certain eligible
"Flex 97" and investor loans, and CMAC has been selected to provide this
coverage on a pilot basis. The Company does not believe that these developments
will adversely affect the demand for or the profitability of mortgage insurance
in the near future.
 
  Indirect Regulation
 
     The Company and CMAC are also indirectly, but significantly, impacted by
regulations affecting originators and purchasers of mortgage loans, particularly
Freddie Mac and Fannie Mae, and regulations affecting governmental insurers such
as the FHA and VA. Private mortgage insurers, including CMAC, are highly
dependent upon federal housing legislation and other laws and regulations which
affect the demand for private mortgage insurance and the housing market
generally. For example, legislation which increases the number of persons
eligible for FHA or VA mortgages could have a material adverse effect on the
Company's ability to compete with the FHA or VA.
 
     The FHA single family loan limits were raised in the fall of 1998. These
increased loan limits vary by geographic region from $109,032 to $197,620. The
Company does not believe that demand for private mortgage insurance has been or
will be materially adversely affected by this change.
 
     Proposals have been advanced which would allow Fannie Mae and Freddie Mac
additional flexibility in determining the amount and nature of alternative
recourse arrangements or other credit enhancements which they could utilize as
substitutes for private mortgage insurance. The Company cannot predict if or
when any of the foregoing legislation or proposals will be adopted, but if
adopted and depending upon the nature and extent of revisions made, demand for
private mortgage insurance may be adversely affected. There can be no assurance
that other federal laws affecting such institutions and entities will not
change, or that new legislation or regulations will not be adopted. In addition,
Fannie Mae and Freddie Mac have entered into, and may in the future seek to
enter into, alternative recourse arrangements or other credit enhancements based
on their existing legislative authority.
 
     In the fall of 1998, Freddie Mac proposed to Congress an amendment to its
charter that would have permitted it to substitute other forms of loss
protection for private mortgage insurance. Although the proposed amendment was
defeated, Freddie Mac may be actively exploring alternatives to conventional
mortgage insurance. Although it is not clear what, if any, changes or new
products may emerge, there is a possibility that any changes in this regard may
materially affect the mortgage insurance industry.
 
     Recent discussions with the Federal Trade Commission with regard to the
adverse action disclosure provisions of the Fair Credit Reporting Act ("FCRA")
have raised the possibility that CMAC will need to make certain changes to its
loan servicing and tracking procedures in order to give FCRA adverse action
notices directly to borrowers. The Company does not believe that such changes
will have a material effect on its operations.
 
     There can be no assurance that the above-mentioned federal laws and
regulations or other federal laws and regulations affecting lenders, private and
governmental mortgage insurers, or purchasers of insured mortgage loans, will
not be amended, or that new legislation or regulations will not be adopted, in
either case, in a manner which will adversely affect the demand for private
mortgage insurance.
 
YEAR 2000 ISSUE
 
     Starting with the year 2000 ("Y2K"), computerized systems and computer
programs which store the year component of a date as two digits may experience
difficulties and produce unexpected results. Arithmetic calculations involving
dates, Boolean expressions involving dates, and program logic testing for the
occurrence of an event may produce errors.
 
                                       18
<PAGE>   20
 
     In 1997, the Company replaced all strategic and mission critical hardware,
including computers, network and communications devices. Additionally, all
operating systems, network operating systems and layered products were upgraded
to Y2K certified versions.
 
     In 1998, the Company allocated approximately 80% of Information Services
("IS") staff to the Y2K software remediation project. Program modifications were
completed in early September 1998. All programs were then unit and system tested
in a dedicated environment capable of date shifting. Testing was performed by
the Company's IS programmers. Their results were verified and the systems
retested by the Company's IS Quality Control department. All test scripts,
procedures and results were documented. The Company believes that it does not
have material exposure to the Y2K issue with respect to its information systems.
 
     The Company continues to analyze whether others with whom it does business
have Y2K issues. These include lenders and the custodian of the Company's
investment accounts. The Company is currently unable to predict the extent to
which the Y2K issue will affect these persons, or the extent to which the
Company would be vulnerable to their failure to remediate any Y2K issues on a
timely basis. The failure of any one of these persons subject to the Y2K issue
to convert its systems on a timely basis or a conversion that is incompatible
with the Company's systems could have a material adverse effect on the Company's
operations.
 
     Currently, the Company believes its most reasonably likely Y2K worst case
scenario would involve the failure of its business partners' loan origination,
renewal processing or default reporting systems. The Company is an active
participant in the mortgage industry Y2K testing project and has developed
contingency plans to minimize the risks of business disruptions resulting from
business partners' Y2K issues. These include:
 
     - accepting non-Y2K compliant data and using "windowing" logic to process
       dates correctly;
 
     - encouraging customers to order mortgage insurance via the internet using
       the Company's MI Online system;
 
     - accepting paper or fax submissions;
 
     - encouraging customers to effect servicing transactions via the internet
       using the Company's ServiceLink system;
 
     - deferring or delaying renewal billing of policyholders to a mutually
       agreed upon date; and
 
     - suspending automatic cancellation for non-payment.
 
With respect to the Company's non-information technology systems, the Company
has made reasonable efforts to contact providers of products and services
concerning their Y2K readiness. Discussions with suppliers of electronic and
electro-mechanical devices deemed critical to the Company's business operations
are ongoing. Based on this contact and discussions, the Company believes that it
does not have material exposure to the Y2K issue with respect to its
non-information systems.
 
     The Company did not incur any significant incremental expense related to
Y2K issues as of December 31, 1998 and does not expect that its Y2K compliance
program will result in any material costs or have any material impact on its
financial condition or results of operations. The Company has not used any
independent verification and/or validation processes to assure the reliability
of its risk and cost estimates.
 
EMPLOYEES
 
     At December 1998, CMAC had 825 employees, of which approximately one-third
were located at its Philadelphia headquarters facility. CMAC's employees are not
unionized and management considers employee relations to be very good.
 
ITEM 2.  PROPERTIES
 
     The Company leases approximately 59,000 square feet for its corporate
headquarters in Philadelphia under leases which expire in 2003. In addition,
CMAC leases space for its Divisional, Service Center and On-Site offices
throughout the United States comprising approximately 57,000 square feet with
leases expiring
 
                                       19
<PAGE>   21
 
between 1999 and 2001. With respect to all facilities, the Company believes it
will be able to obtain satisfactory lease renewal terms.
 
     The Company believes its existing properties are well utilized and are
suitable and adequate for its present circumstances.
 
     The Company maintains a mini-computer network from its corporate data
center located in its headquarters building to support its data processing
requirements for accounting, claims, marketing, risk management, underwriting
and non-insurance operations. In 1997, the Company centralized all computer
operations. All the service centers are linked to the home office in
Philadelphia via a high speed frame-relay network. The centralized environment
is based on the Business Recovery Server ("BRS") architecture. The BRS consists
of two geographically dispersed, identical data centers. Each data center is
currently running at 30% of capacity. Either data center is capable of
supporting the entire company. The data centers are linked via a fibre-optic
link allowing simultaneous data updates through disk shadowing. Each center is
part of a separate power grid. This redundant configuration provides disaster
tolerance and automatic back-up, resource sharing and fail-over.
 
ITEM 3.  LEGAL PROCEEDINGS
 
     CMAC is involved in certain litigation arising in the normal course of its
business. CMAC is contesting the allegations in each pending action and
believes, based on current knowledge and after consultation with counsel, that
the outcome of such litigation will not have a material adverse effect on the
Company's consolidated financial position and results of operations.
 
ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
     No matter was submitted during the fourth quarter of 1998 to a vote of
holders of the Company's common stock.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
1998 COMPARED TO 1997
 
     Net income for 1998 was $91.1 million, a 20.5% increase compared to $75.0
million for 1997. This improvement was a result of significant growth in
premiums earned, net investment income and other income, partially offset by a
higher provision for losses, policy acquisition costs and other operating
expenses.
 
                                       21
<PAGE>   23
 
     New primary insurance written during 1998 was $21.9 billion, a 59.6%
increase compared to $13.7 billion for 1997. The increase in CMAC's primary new
insurance written was primarily due to a 55.3% increase in primary new insurance
written volume in the private mortgage insurance industry for 1998 as compared
to 1997. In addition, CMAC completed a bulk transaction in the second quarter of
1998, insuring approximately $700 million of seasoned California loans with a
risk profile similar to the Company's regular business. CMAC's market share of
the industry volume increased to 11.5% in 1998, compared to 11.2% for 1997.
Additionally, in 1998, CMAC wrote an increased amount of pool insurance which
represented risk written of $389.4 million as compared to $277.5 million in
1997. Most of this pool insurance volume relates to a group of structured
transactions composed primarily of Fannie Mae- and Freddie Mac-eligible
conforming mortgage loans that are geographically well dispersed throughout the
United States and have lower average loan-to-value ratios than CMAC's primary
business. The performance of this business to date has been better than
anticipated although the business is relatively young and the historical
performance might not be an indication of future performance. Under a pool
insurance transaction, the exposure to CMAC on each individual loan is uncapped;
however, the aggregate stop-loss percentage (typically 1.0% to 1.5% of the
aggregate original loan balance in the Fannie Mae/Freddie Mac transactions) is
the maximum that can be paid out in losses before the insurer's exposure
terminates. The Company expects its pool insurance activity to decline during
1999 as certain outstanding commitments expire and are not renewed. Premium
rates on such pool insurance are significantly lower than on primary insurance
loans due to the low stop-loss levels, which limit the overall risk exposure to
CMAC, and the focus of such product on high quality primary insurance customers.
Both S&P and Moody's have determined that the capital requirements to support
such pool insurance will be significantly more stringent than on primary
insurance due to the low premium rates.
 
     CMAC's volume in 1998 was positively impacted by low interest rates which
affected the entire mortgage industry. The trend toward lower interest rates,
which began in the third quarter of 1997, caused refinancing activity during
1998 to continue at a higher rate than normal and strong housing prices have
caused a large percentage of the refinanced loans to be closed without private
mortgage insurance at an LTV of 80% or below. Therefore, the rate of growth in
the private mortgage industry has not been as high as that of the entire
mortgage market. CMAC's refinancing activity as a percentage of primary new
insurance written was 32.0% for 1998 as compared to 17.0% in 1997. However, for
the fourth quarter of 1998, refinanced loans represented 38.0% of new primary
insurance written as compared to only 24.0% for the third quarter of 1998 as a
result of the slight decline in interest rates during the fourth quarter. The
persistency rate, which is defined as the percentage of policies in force that
are renewed in any given year, was 68.0% for 1998 as compared to 84.2% for 1997.
This large decline was consistent with the increase in the level of refinancing
activity during 1998. The persistency rate for the beginning of 1999 should
continue at a level similar to 1998 although if the current refinance boom
slows, the persistency rate could improve.
 
     CMAC also has recently become involved in insuring non-conforming loans,
specifically Alternative A and A minus loans. Alternative A borrowers have an
equal or better credit profile than CMAC's typical insured borrowers, but these
loans are underwritten with reduced documentation and verification of
information. CMAC typically charges a higher premium rate for this business due
to the reduced documentation, but does not consider this business to be
significantly more risky than its normal primary business. The A minus loan
programs typically have non-traditional credit standards which are less
stringent than standard credit guidelines. To compensate for this additional
risk, CMAC receives a significantly higher premium for insuring this product
that is commensurate with the additional default risk. During 1998, Alternative
A and A minus business accounted for 7.6% of CMAC's new primary insurance
written.
 
     Net premiums earned in 1998 were $282.2 million, an 18.7% increase compared
to $237.7 million for 1997. This increase reflected the insurance in force
growth resulting from strong new insurance volume and the increase in pool
insurance written during 1998, and was partially offset by the decline in
persistency levels. The strong volume led to an increase in direct primary
insurance in force during 1998 of 14.6%, from $46.9 billion at December 31, 1997
to $53.8 billion at December 31, 1998. Direct pool risk in force also grew to
$907.3 million at December 31, 1998 from $593.9 million at the end of 1997, an
increase of 52.8% for the year. CMAC and the industry have entered into
risk-sharing arrangements with various customers that are designed to allow the
customer to participate in the risks and rewards of the mortgage insurance
business. One such
 
                                       22

product is captive reinsurance, in which a mortgage lender sets up a mortgage
reinsurance company that assumes part of the risk associated with that lender's
insured book of business. In most cases, the risk assumed by the reinsurance
company is an excess layer of aggregate losses that would be penetrated only in
a situation of adverse loss development. For 1998, premiums ceded under captive
reinsurance arrangements were $1.5 million or less than 1% of total premiums
earned during 1998 and new primary insurance written under captive reinsurance
arrangements was $2.6 billion, or 12.1% of total new primary insurance written.
CMAC expects to enter into several new agreements in 1999, although the
aggregate amount of captive reinsurance is not expected to have a material
financial impact on CMAC's balance sheet or financial results in 1999.
 
     Net investment income for 1998 was $38.6 million, a 14.1% increase compared
to $33.8 million in 1997. This increase was a result of continued growth in
invested assets primarily due to positive operating cash flows of $132.3 million
during 1998. The Company has continued to invest new operating cash flow in tax-
advantaged securities, primarily municipal bonds, although the Company did
modify its investment policy to allow the purchase of various other asset
classes, including common stock and convertible securities, beginning in the
second quarter of 1998. The Company's intent is to target the common equity
exposure at a maximum of 5% of the investment portfolio's market value while the
convertible securities and mortgage-backed securities exposures are targeted not
to exceed 10% each. During 1998, the Company purchased a total of $26.0 million
of common equities which led to a slight decrease in the growth in investment
income during 1998. Although there will be a short-term decline in investment
income from this change in investment policy, the Company expects no material
long-term impact on total investment returns as a result of this investment
diversification.
 
     The provision for losses was $132.0 million in 1998, an increase of 12.7%
compared to $117.1 million in 1997. This increase reflected the significant
growth and maturation of CMAC"s book of business over the past several years,
which has caused an increase in the number of defaults reported to CMAC, the
continued adverse experience of California loans (despite signs of an improving
trend in California), and the continued poor experience of certain "affordable
housing" program loans insured in 1994 and 1995, especially in Florida. Although
the ultimate performance of the books of business that originated since 1994
cannot yet be determined, it appears that the ultimate loss levels will be
slightly higher than average, partially due to the presence of these "affordable
housing" loans. Claim activity is not evenly spread throughout the coverage
period of a book of business. Relatively few claims are received during the
first two years following issuance of the policy. Historically, claim activity
has reached its highest level in the third through fifth years after the year of
loan origination. Approximately 58% of CMAC's primary risk in force and almost
all of CMAC's pool risk in force at December 31, 1998 had not yet reached its
anticipated highest claim frequency years. CMAC's overall default rate at
December 31, 1998 was 1.68% as compared to 1.82% at December 31, 1997, while the
default rate on the primary business was 2.44% at December 31, 1998 as compared
to 2.32% at December 31, 1997. The number of defaults rose from 12,359 at
December 31, 1997 to 15,525 at December 31, 1998 and the average loss reserve
per default rose from $12,026 at the end of 1997 to $12,965 at December 31,
1998. This increase in average loss reserve per default reflected the Company's
continued implementation of a more conservative reserve calculation for certain
loans in default perceived as having a higher risk of claim incidence. In
addition, an increase in the average loan balance and the coverage percentage on
loans originated beginning in 1995 has necessitated a higher reserve balance on
loans in a default status due to the increased ultimate exposure on these loans.
The default rate in California was 2.6% (including pool) at December 31, 1998 as
compared to 3.6% at December 31, 1997 and claims paid in California during 1998
were $41.8 million, representing approximately 43.1% of total claims as compared
to 57.0% in 1997. California represented 18.3% of primary risk in force at
December 31, 1998 as compared to 18.6% at December 31, 1997. The default rate in
Florida was 3.6% (including pool) at December 31, 1998 as compared to 3.8% at
December 31, 1997 and claims paid in Florida during 1998 were $11.5 million,
representing approximately 11.9% of total claims as compared to only 6.6% in
1997. Florida represented 8.2% of primary risk in force at December 31, 1998 as
compared to 8.3% at December 31, 1997. The "affordable housing" early default
experience is a result of insuring certain loans in which the borrowers'
principal and interest reserves and other credit factors were not as strong as
on prior years' books of business. Certain underwriting changes were implemented
near the end of 1996 to compensate for the factors that contributed to the early
default experience on these "affordable housing" loans; however, it is too early
to determine the impact of such changes. In addition, the Company has
                                       23
<PAGE>   25
 
reported an increased number of defaults on the Alternative A and A minus
business insured beginning in 1997. Although the default rate for this business
is higher than on CMAC's normal books, it is not currently higher than was
expected for this type of business and the higher premium rates charged are
expected to compensate for the increased level of risk. Direct losses paid in
1998 were $83.8 million as compared to direct losses paid during 1997 of $82.1
million, an increase of only 2.1%.
 
     Underwriting and other operating expenses were $75.1 million for 1998, an
increase of 30.3% compared to $57.7 million for 1997. These expenses consisted
of policy acquisition expenses, which relate directly to the acquisition of new
business, and other operating expenses, which primarily represent contract
underwriting expenses, overhead and administrative costs.
 
     Policy acquisition costs were $36.1 million in 1998, an increase of 15.5%
compared to $31.3 million in 1997. This increase reflects the growth in variable
sales- and underwriting-related expenses relating to the Company's continued
growth in new insurance written. The Company has continued development of its
marketing infrastructure needed to support a focus on larger, national mortgage
lenders in order to take advantage of the widespread consolidation occurring in
the mortgage lending industry. Other operating expenses for 1998 were $39.0
million, an increase of 47.8% compared to $26.4 million for 1997. Most of the
increase continued to result from an increase in expenses associated with the
Company's ancillary services, specifically contract underwriting. Contract
underwriting expenses for 1998 included in other operating expenses were $20.7
million as compared to $10.6 million for 1997, an increase of 96.3%. The $10.1
million increase in contract underwriting expenses during 1998 represented 80.9%
of the $12.6 million increase in other operating expenses. Some of these
additional contract underwriting expenses were correspondingly offset by
increases to other income, which rose 112.2% from $5.0 million in 1997 to $10.6
million in 1998. During 1998, loans underwritten via contract underwriting
accounted for 33% of applications, 29% of insurance commitments, and 24% of
certificates issued by CMAC as compared to 29% of applications, 25% of
commitments and 22% of certificates in 1997. In 1999, these percentages are
expected to increase if there is a decrease in refinancing activity. Changing
market conditions have caused the cost of contract underwriting to increase
during 1997 and 1998 due to the high demand for available resources. However, as
further efficiencies are realized in the contract underwriting process due to
the integration with Freddie Mac's Loan Prospector and Fannie Mae's Desktop
Underwriter origination systems, the cost per contract underwriting loan
underwritten could decrease.
 
     The effective tax rate for 1998 was 27.6% as compared to 26.9% for 1997.
Operating income accounted for 68.1% of net income in 1998 as compared to 66.2%
in 1997 thus resulting in the increase in effective tax rate for 1998.
 
1997 COMPARED TO 1996
 
     Net income for 1997 was $75.0 million, a 20.5% increase compared to $62.2
million for 1996. This improvement was a result of significant growth in
premiums earned and net investment income, partially offset by a higher
provision for losses, policy acquisition costs and other operating expenses.
 
     New primary insurance written during 1997 was $13.7 billion, an 11.4%
increase compared to $12.3 billion for 1996. This increase reflected a market
share increase which was primarily due to CMAC's continued focus on large,
national primary insurance customers and continued geographic expansion into
markets previously underrepresented by CMAC such as the Northwest and Midwest.
The increase resulted despite a 4.4% decline in new insurance written volume in
the private mortgage insurance industry in 1997. CMAC's market share of the
industry increased to 11.2% in 1997, compared to 9.6% for 1996 and for the
fourth quarter of 1997, CMAC's market share was 12.1%. Additionally, in 1997,
CMAC wrote an increased amount of pool insurance which represented an addition
to risk of $277.5 million as compared to $108.9 million in 1996. Most of this
pool insurance volume related to a group of structured transactions composed
primarily of Fannie Mae- and Freddie Mac-eligible conforming mortgage loans that
are geographically dispersed throughout the United States and that have lower
average loan-to-value ratios than CMAC's primary business. Under a pool
insurance transaction, the exposure to CMAC on each individual loan is uncapped;
however, the aggregate stop-loss percentage (typically 1.0% to 1.5% in the
Fannie Mae/Freddie
 
                                       24
<PAGE>   26
 
Mac transactions) is the most that can be paid out in losses before the
insurer's exposure terminates. The Company expects its pool insurance activity
to continue at this same level in 1998 due its demand in the marketplace.
Premium rates on such pool insurance are significantly lower than on primary
insurance loans due to the low stop-loss levels, which limit the overall risk
exposure to CMAC, and the focus of such product on high quality primary
insurance customers. Nonetheless, this pool insurance has contributed to the
increase in earned premiums during 1997. Standard & Poor's has recently
determined that the capital requirements to support such pool insurance will be
significantly more stringent than on primary insurance due to the low premium
rates and CMAC has reviewed its capital levels to ensure compliance with these
requirements. The average stop-loss on pool insurance written during 1997 was
1.5%.
 
     Refinanced loans represented 17.0% of new primary insurance written during
1997 as compared to 16.5% in 1996. However, for the fourth quarter of 1997,
refinanced loans represented 21.8% of new primary insurance written as compared
to only 13.4% for the fourth quarter of 1996 as lower interest rates in the
third quarter of 1997 caused refinance activity to increase significantly in the
fourth quarter. The persistency rate was 84.2% for 1997 as compared to 83.9% for
1996. This increase was consistent with the slight decline in the level of
refinancing activity during 1997.
 
     The majority of CMAC's business in 1997 reflected the deeper insurance
coverage required by Fannie Mae and Freddie Mac beginning in 1995. That
coverage, which is 25% on loans written with an LTV between 85.01% and 90% and
30% on loans with LTVs greater than 90%, results in higher premiums and losses
than the older coverages of 17% and 22%, respectively, but should not materially
affect the Company's financial results. Approximately 60% of CMAC's direct
primary insurance in force had such deeper coverage at the end of 1997. Monthly
premium plans, which allow borrowers to pay premiums on a monthly basis rather
than annually in advance, accounted for 93.8% of CMAC's primary new insurance
written in 1997 as compared to 91.6% in 1996. Although this program reapportions
the cash flow from an insured loan over the life of the loan, there should be no
material financial effect from its widespread use. At the end of 1995, the
industry and CMAC introduced a variation of the monthly premium plan in which
the borrower does not need to pay any mortgage insurance premium at closing and
under which some portion of the first month's premium can be deferred or
forgiven. During 1997, business written under this program was approximately 31%
of CMAC's total as compared to 11% in 1996.
 
     Net premiums earned in 1997 were $237.7 million, a 26.5% increase compared
to $187.9 million for 1996. This increase reflected a continuation of high
persistency levels, the insurance in force growth resulting from strong new
insurance volume, increased premium rates on deeper coverages and higher
LTV-insured products during 1997 and the increase in pool insurance written
during 1997. The strong volume and high persistency led to an increase in direct
primary insurance in force during 1997 of 18.9%, from $39.4 billion at December
31, 1996 to $46.9 billion at December 31, 1997. Direct pool risk in force also
grew to $593.9 million at December 31, 1997 from $341.9 million at the end of
1996, an increase of 73.7% for the year. Primary new insurance written on loans
with LTVs greater than 90% represented 42.1% of the total amount written in 1997
as compared to 45.5% in 1996.
 
     Net investment income for 1997 was $33.8 million, a 12.6% increase compared
to $30.0 million in 1996. This increase was a result of continued growth in
invested assets primarily due to positive operating cash flows of $93.5 million,
offset slightly by a small decrease in investment yields. The Company's pre-tax
investment yield declined from 6.2% at December 31, 1996 to 6.0% at December 31,
1997. The Company has continued to invest new operating cash flow in
tax-advantaged securities, primarily municipal bonds.
 
     The provision for losses was $117.1 million in 1997, an increase of 27.5%
compared to $91.9 million in 1996. This increase reflected the significant
growth and maturation of CMAC's book of business over the past several years,
the continued adverse experience of California loans, and the relatively poor
experience of certain "affordable housing" program loans insured starting in
1994. Although the ultimate performance of the books of business that originated
since 1994 cannot yet be determined, it appears that the ultimate loss levels
will be higher than average, due in part to the presence of these "affordable
housing" loans. CMAC's overall default rate at December 31, 1997 was 1.8% as
compared to 2.1% at December 31, 1996. The number of defaults rose from 10,127
at December 31, 1996 to 12,359 at December 31, 1997 and the average loss reserve
 
                                       25
<PAGE>   27
 
per default rose from $10,685 at the end of 1996 to $12,026 at December 31,
1997. This increase in average loss reserve per default reflected the Company's
continued implementation of a more conservative reserve calculation for certain
loans in default perceived as having a higher risk of claim incidence. In
addition, an increase in the coverage percentage on loans originated beginning
in 1995 has necessitated a higher reserve balance on loans in a default status
due to the increased ultimate exposure on these loans. The default rate in
California was 3.6% (including pool) at December 31, 1997 as compared to 4.0% at
December 31, 1996 and claims paid in California during 1997 were $48.2 million,
representing approximately 57.0% of total claims as compared to 61.9% in 1996.
The "affordable housing" early default experience is a result of insuring
certain loans in which the borrowers' principal and interest reserves and other
credit factors were not as strong as on prior years' books of business. Certain
underwriting changes were implemented near the end of 1996 to compensate for the
factors that contributed to the early default experience on these "affordable
housing" loans; however, it is too early to determine the impact of such
changes. The Company believes that many loan servicers have changed the timing
of reporting loans in default, which has continued to result in an incremental
increase in the number of loans in default. This change allows for earlier
intervention with borrowers in default, which might lead to a higher cure rate
for such loans.
 
     Underwriting and other operating expenses were $57.7 million for 1997, an
increase of 19.8% compared to $48.1 million for 1996. These expenses consisted
of policy acquisition expenses, which relate directly to the acquisition of new
business, and other operating expenses, which primarily represent overhead and
administrative costs.
 
     Policy acquisition costs were $31.3 million in 1997, an increase of 16.5%
compared to $26.9 million in 1996. This reflects the increase in sales-and
underwriting-related expenses relating to the Company's continued market share
expansion and the development of the Company's marketing infrastructure needed
to support a focus on larger, national mortgage lenders in order to take
advantage of the widespread consolidation occurring in the mortgage lending
industry. Other operating expenses for 1997 were $26.4 million, an increase of
24.0% compared to $21.3 million for 1996. Much of the increase continued to
result from an expansion of the Company's technology efforts and an increase in
expenses associated with the company's ancillary services, specifically contract
underwriting. Some of these additional contract underwriting expenses were
correspondingly offset by increases to other income, which rose 31.9% from $3.8
million in 1996 to $5.0 million in 1997, although the main purpose of the
contract underwriting effort is to support the sales effort by generating
incremental mortgage insurance business. During 1997, loans underwritten via
contract underwriting accounted for 29% of applications, 25% of insurance
commitments, and 22% of certificates issued by CMAC as compared to 35% of
applications, 21% of commitments and 18% of certificates in 1996. Changing
market conditions caused the cost of contract underwriting to increase during
1997 due to the shortage of available resources.
 
     The effective tax rate for 1997 was 26.9% as compared to 24.6% for 1996.
Operating income was 66.2% of pretax income in 1997 as compared to 62.6% in
1996, thus resulting in the increase in effective tax rate for 1997.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company's sources of funds consist primarily of premiums and investment
income. Funds are applied primarily to the payment of CMAC's claims and
operating expenses. The Company generated positive cash flows from operating
activities in 1998, 1997 and 1996 of $132.3 million, $93.5 million and $84.5
million. The significant increases in operating cash flows reflect the growth in
premiums written and insurance in force that has more than offset any increases
in claims paid and other expenses. Positive cash flows are invested pending
future payments of claims and other expenses; cash flow shortfalls, if any, are
funded primarily through sales of short-term investments and other investment
portfolio securities.
 
     Total investments were $736.3 million at December 31, 1998, including $18.6
million of short-term investments with maturities of 90 days or less and $45.5
million of U.S. Treasury equivalents and government agency securities. At
December 31, 1998, approximately 96.3% of the Company's investments consisted of
money market and investment-grade, readily marketable, fixed-income securities,
concentrated in maturities
 
                                       26
<PAGE>   28
 
of greater than five years. In addition, at December 31, 1998, the Company's
investment portfolio included $27.4 million of equity securities, which includes
convertible debt and convertible preferred stock.
 
     Loss reserves increased from $148.6 million at December 31, 1997 to $201.3
million at December 31, 1998. This increase in loss reserves due to newly
reported defaults, new loans in default that were not reported, and increases to
loss reserves on existing defaults was a result of continued adverse California
and Florida experience as well as the continued growth of the in force insurance
book. In addition, an increase in the average loan balance and the coverage
percentage on loans originated beginning in 1995 has necessitated a higher
reserve balance on loans in a default status due to the increased ultimate
exposure on these loans. CMAC has experienced abnormally high early defaults on
the 1994 and 1995 origination year books of business, which reflected the
increase in "affordable housing" program loans insured in the period. CMAC also
experienced an increase in defaults under the Alternative A and A minus programs
insured starting in late 1997 which is a typical pattern for such business.
Unearned premiums increased slightly from $49.3 million at December 31, 1997 to
$49.4 million at December 31, 1998 due to unearned premium resulting from the
bulk loan transaction insured in 1998 and from certain pool insurance
transactions.
 
     Stockholders' equity plus redeemable preferred stock increased to $563.0
million at December 31, 1998, an increase of 19.8% from $469.9 million at
December 31, 1997. This increase resulted primarily from net income for 1998 of
$91.1 million, a $2.6 million increase (net of tax) in the market value of
securities available for sale and proceeds from the issuance of common stock of
$5.4 million, offset by $6.0 million of dividends.
 
     As protection against a period of adverse loss development, the Company has
entered into a variable quota share reinsurance treaty for the primary books of
business originated in 1994, 1995, 1996 and 1997 as well as some portion of the
pool book of business originated in 1997. As per the terms of the reinsurance
treaties, the Company receives variable quota share loss relief at levels
ranging from 7.5% to 15.0% based upon the loss ratio on the covered book of
business. A ceding commission is paid by the reinsurer to the Company except for
certain circumstances where the loss ratio on the covered book exceeds a stated
level. These treaties remain in force for a period of ten years and are
noncancelable by either party until after ten years have elapsed except under
certain circumstances. Premiums are payable to the reinsurer on a quarterly
basis net of ceding commissions due to the Company and any losses calculated
under the variable quota share coverage are recovered on a quarterly basis. At
the end of the fourth, seventh and tenth years of each treaty, depending on the
extent of losses recovered to date on the calendar year quota share portion of
the treaty, a calculation is made to determine an amount of Underwriting Year
Excess Coverage, if any, due to the Company.
 
     As part of its Year 2000 remediation effort, the Company will upgrade all
desktop and laptop personal computers and vendor software programs that are not
currently Year 2000 compliant (see Year 2000 Issue below) during 1999. The cost
of this upgrade is currently estimated at $814,000. In addition, the Company
plans to implement system and network monitoring software during 1999 at a cost
of approximately $200,000 that will enhance the efficiency of the Company's
operating systems.
 
     The Company believes that CMAC will have sufficient funds to satisfy its
claims payments and operating expenses and to pay dividends to the Company for
at least the next 12 months. The Company also believes that it will be able to
satisfy its long-term (more than 12 months) liquidity needs with cash flow from
CMAC. As a holding company, the Company conducts its principal operations
through CMAC. The company's ability to pay dividends on the $4.125 Preferred
Stock is dependent upon CMAC's ability to pay dividends or make other
distributions to the Company. Based on the company's current intention to pay
quarterly common stock dividends of approximately $0.03 per share, the Company
will require distributions from CMAC of $6.0 million annually to pay the
dividends on the outstanding shares of $4.125 Preferred Stock and common stock.
There are regulatory and contractual limitations on the payment of dividends or
other distributions (See note 7 to the Consolidated Financial Statements.) The
Company does not believe that these restrictions will prevent the payment by
CMAC or the Company of these anticipated dividends or distributions in the
foreseeable future.

YEAR 2000 ISSUE
 
     Many existing computer programs use only two digits to identify a year in
the date field. These programs were designed and developed without considering
the impact of the upcoming change in the century. If not corrected, many
computer applications could fail or create erroneous results by or at the year
2000. The Company has conducted an analysis of its systems and has completed its
Year 2000 project with the result that all of its systems were Year 2000
compliant by the end of 1998. "Year 2000 compliant" means fault-free performance
in the processing of data and date related data (including, but not limited to,
calculating, comparing and sequencing) by all hardware and software products,
individually and in combination. Fault-free performance must include the
manipulation of data when dates are in the 20th or 21st century and must be
transparent to the user.
 
     The Company has completed the necessary program modifications to make them
Year 2000 compliant and all date sensitive files have been appropriately
modified and updated. The Company has built a stand-alone testing environment
that allowed simulation of different year-end scenarios and testing of the Year
2000 programming changes and file modifications was completed in October 1998.
In addition, the Company has undertaken a review of all of its hardware systems
to assess Year 2000 compliance. The Company's servers are currently Year 2000
compliant and any desktop or laptop systems not currently Year 2000 compliant
are scheduled for replacement in 1999.
 
     Although the Company will be Year 2000 compliant, in the event that third
parties with whom the Company transacts business are not Year 2000 compliant,
potential for an adverse effect on the Company's operations may remain. The
Company has taken precautions to minimize this risk by contacting each of its
mission critical business partners to ascertain their Year 2000 compliance
status. Currently, the Company believes its most reasonably likely Year 2000
worst case scenario would involve the failure of its business partners' loan
origination, renewal processing or default reporting systems. The Company is an
active participant in the mortgage industry's Year 2000 testing project and has
developed contingency plans to minimize the risks of business disruptions
resulting from its business partners' Year 2000 issues.
 
     With respect to the Company's non-information technology systems, the
Company has made reasonable efforts to contact providers of products and
services concerning their Year 2000 readiness. Discussions with suppliers of
electronic and electro-mechanical devices deemed critical to the Company's
business operations are ongoing. Based on this contact and discussions, the
Company believes that it does not have material exposure to the Year 2000 issue
with respect to its non-information systems.
 
     The Company did not incur any significant incremental expense related to
Year 2000 issues during 1998 and does not expect that its Year 2000 compliance
program will result in any material costs or have a material impact on its
financial condition or results of operations. The Company has not used any
independent verification and/or validation processes to assure the reliability
of its risk and cost estimates.

a Committee, and a $1,500 fee for each Board of Directors meeting, a $1,500 fee
for each committee meeting attended not in conjunction with a Board of Directors
meeting and a $500 fee for each committee meeting attended in conjunction with a
Board of Directors meeting attended in 1998. In addition, non-employee directors
are reimbursed for their out-of-pocket expenses incurred in connection with a
Board of Directors or Committee meeting. Directors who are employees do not
receive additional compensation for such service. Each non-employee director
automatically receives, at each December Board of Directors meeting, an option
under the Company's stock option plan to acquire 1,200 shares of Common Stock of
the Company at the fair market value of such Common Stock on the date of the
grant. These options become vested and fully exercisable on the first
anniversary of the date of the grant, provided that the optionee is a director
of the Company on such anniversary date. Options are exercisable for ten years
after the date of the grant, provided that the optionee remains a director of
the Company. The exercise price of such options is 100% of the fair market value
of the Common Stock on the date of the grant. In 1997, the Directors of the
Company undertook, with the assistance of an outside consultant, a review of the
Company's policies with respect to director and board compensation.

PENSION PLAN
 
     The Board of Directors of the Company has established the CMAC Investment
Corporation Pension Plan (the "Pension Plan"). The Pension Plan is intended to
be tax-qualified under Section 401(a) of the Internal Revenue Code. All salaried
and hourly employees of the Company are eligible to participate in the Pension
Plan upon the attainment of 20 years of age and one year of eligible service. A
participant is generally fully vested after five years of service subsequent to
age 18.
 
     The amount of the annual normal retirement benefit of a participant is the
sum of (i) 1.1% of his average base salary (up to a statutory maximum equal to
$160,000 in 1998) for the five consecutive calendar years for which such average
is highest ("Average Annual Salary") multiplied by his number of years of
credited service not in excess of 35 years, plus (ii) 0.5% of the participant's
Average Annual Salary in excess of the average of the annual Social Security
taxable wage bases in effect for each of the 35 calendar years ending with the
calendar year in which he attains Social Security retirement age multiplied by
his number of years of credited service not in excess of 35 years, plus (iii)
0.5% of the participant's Average Annual Salary multiplied by his number of
years of credited service in excess of 35 years.
 
     In January 1997, the Board of Directors of the Company established a
nonqualified Supplemental Executive Retirement Plan ("SERP"). This plan is
intended to provide certain executive officers with a supplemental retirement
program to the qualified pension plan. The difference between the SERP and the
qualified pension plan is that the SERP is not subject to the statutory cap on
compensation that may be taken into account for the calculation of benefits
($160,000 in 1998) and the statutory cap on actual benefits ($130,000 in 1998).
The benefit under the SERP is determined using the same formula as that under
the qualified pension plan but is based on total compensation (inclusive of
salary and bonus) up to 150% of average base pay for the three consecutive
calendar years for which such base pay is the highest. Under the terms of the
SERP, the Board of Directors must annually designate which executive officers
are eligible to participate in the SERP.
 
     The following table sets forth the approximate annual pension that a
full-time employee, including an executive officer, may receive under the
Pension Plan, assuming selection of a single life annuity and
 
                                       33

retirement at age 65, based on the indicated assumptions as to Average Annual
Salary and years of credited service. The following table assumes that the
Company was in existence for the entire year of 1992. Benefits shown in the
following table in excess of $130,000 are payable by the Company only to persons
designated by the Board of Directors as participants in the SERP.

STOCK OPTION AND COMPENSATION COMMITTEE REPORT ON COMPENSATION OF EXECUTIVE
OFFICERS OF THE COMPANY
 
     The Stock Option and Compensation Committee (the "Committee") has provided
the following report on executive compensation for the year ended December 31,
1998:
 
COMPENSATION PHILOSOPHY
 
     The Committee believes that the Company's executive compensation program
should be closely related to the services that the executives deliver to the
Company and the value such services bring to the stockholders of the Company.
 
     The Committee believes an executive's compensation should be based, in
part, on the achievement by the Company of certain specified financial
objectives and, in part, on the achievement by the executive of specific,
individual objectives. The Company's financial objectives are recommended by
management and are approved by the Stock Option and Compensation Committee and
further ratified by the full Board of Directors. Achievement of both the
corporate and individual objectives should lead to improved performance and
greater value to the stockholders. The Stock Option and Compensation Committee
hired an outside consultant to review the Company's compensation programs in
light of those provided by similar organizations.
 
EXECUTIVE OFFICERS
 
     The Company's executive compensation program is comprised of three
components: (i) annual base salary; (ii) annual bonus; and (iii) long-term
equity incentives. The variable portions of the executive compensation program
(annual bonus and stock options) are directly tied to the Company's results of
operations. The annual bonus has been designed to recognize shorter-term results
while awards of stock options have been implemented to recognize sustained
corporate growth and profitability. The annual bonus plan is designed to reflect
the achievement of specific individual and corporate goals and objectives
including specific net income and return on equity targets. The amount of the
annual bonus actually awarded to an executive officer is dependent on the
meeting or exceeding of specific targets which are developed at the
 
                                       34
<PAGE>   36
 
beginning of each year by the executive and the Company. Failure to reach the
targeted goals results in lower annual bonus awards and may, in the appropriate
circumstances, result in no award. Since the attainment of the goals and
objectives of the Company leads to increased stockholder returns, the annual
bonus plan creates a direct relationship between executive compensation and the
creation of additional value for the stockholders.
 
COMPENSATION OF THE CHIEF EXECUTIVE OFFICER
 
     Mr. Filipps' annual compensation is fixed by the Committee. The Committee
may grant periodic salary increases, if warranted, after a review of Mr.
Filipps' performance and an assessment of the competitiveness of Mr. Filipps'
current base salary. The award of an annual bonus recognizes Mr. Filipps'
contributions to the Company's overall results. Contributions are measured
against specific goals and objectives which are established by the Committee at
the beginning of each year. The Committee considers the Company's return on
equity, combined ratio, market share, growth in earnings and revenue, reduction
in expenses, increases in profitability, as well as Mr. Filipps' individual
goals and objectives.
 
ANNUAL BASE SALARY
 
     The annual base salary levels for the Company's executive officers are
intended to be competitive with salaries for executive officers in comparable
industries with similar levels of responsibility. The Company believes the
salaries are competitive. Salaries paid to executive officers are fixed by the
Committee. The Committee grants periodic salary increases, if warranted, after a
review of individual performance and an assessment of the competitiveness of the
executive's current salary.
 
ANNUAL BONUS
 
     The award of an annual bonus recognizes the individual contributions of an
executive officer to the Company's overall results of operations. Contributions
are measured against specific goals and objectives established at the beginning
of the year for each executive officer and the Company. Among the factors
considered are the Company's return on equity, combined ratio, market share,
growth in earnings and revenue, reduction in expenses, increases in
productivity, etc. Individual objectives are based on the executive's position
with the Company or an affiliate.
 
     The President and the next three most highly compensated executive officers
of the Company are eligible for bonuses of 100% of their annual base salary.
Subject to the requirements of Section 162(m) of the Internal Revenue Code, as
discussed in detail below, a bonus in excess of 100% may be awarded at the
discretion of the Board of Directors. In addition to the bonus eligibility of
the highly compensated executive officers as indicated above, the remaining
executive officers of the Company have the opportunity to earn annual bonuses
ranging from 50% to 75% of their annual base salary.
 
     The Chairman and the President of the Company review the performance of all
executive officers and make specific recommendations to the Committee regarding
the amount of annual bonus, if any, to be awarded. The amount of the annual
bonus is dependent upon achieving specific goals and objectives.
 
LONG-TERM EQUITY INCENTIVE
 
     The Company's 1992 Stock Option Plan and 1995 Equity Compensation Plan
provide the Company the opportunity to reward the contributions of key
employees, executive officers and others. In 1994, the Company undertook a
review of the compensation practices of corporations similar in size and/or
business to the Company. Based on this review, the President determined that the
use of stock option awards based on salary levels was the best method of
long-term incentive compensation of executive officers, and one that would
ensure that the executive officers hold equity stakes in the Company. The
Company's management modified the existing stock option grant guidelines and
suggested that the Committee adopt these modifications. Based upon the review
and management's recommendations, the Committee approved guidelines that provide
for stock option grants to executive officers (and key employees) upon the
occurrence of one (or more) of the following events: (i) initial employment,
(ii) promotion to a new, higher level position with increased responsibility and
accountability, and/or, (iii) the attainment of specific goals and objectives by
an executive
                                       35
<PAGE>   37
 
officer or key employee and the Company. Pursuant to these guidelines, the
President recommends the number of stock options to be granted to an executive
officer (or key employee) and presents this recommendation to the Committee
along with supporting data for its review and approval. The President may make a
recommendation to the Committee that deviates from the guidelines in appropriate
circumstances.
 
     The Committee reviews the individual performance of Messrs. Wender and
Filipps. Mr. Filipps reviews the performances of the executive officers of the
Company and makes specific recommendations to the Committee regarding
eligibility for and the amount of stock options to be granted to those executive
officers (and key employees) of the Company he feels have made significant
contributions to the Company's results of operations.
 
     The Committee evaluates the performance of the Company during a calendar
year by examining a number of factors including the Company's competitive
position in the mortgage insurance industry, growth in earnings, return on
equity and other specific corporate goals and objectives. The Committee also
examines the recommendations of the Chief Executive Officer. The Committee
grants, subject to approval and ratification by the Board of Directors, stock
options to the Chief Executive Officer and other executive officers and key
employees.
 
     During 1998, the executive officers of the Company as a group were not
granted options to purchase shares.
 
COMPLIANCE WITH INTERNAL REVENUE CODE SECTION 162(m)
 
     Section 162(m) of the Internal Revenue Code, enacted in 1993, generally
disallows a tax deduction to public companies for compensation over $1 million
paid to a corporation's Chief Executive Officer and the four next most highly
compensated executive officers except to the extent that any amount in excess of
such limit is paid pursuant to a plan containing a performance standard or a
stock option plan that meets certain requirements. The amendments for the 1992
Stock Option Plan approved at the 1995 Annual Meeting were designed to bring the
1992 Stock Option Plan into compliance with Section 162(m). The 1995 Equity
Compensation Plan was also drafted to comply with Section 162(m). To the extent
readily determinable and as one of the factors in its consideration of
compensation matters, the Stock Option and Compensation Committee considers the
anticipated tax treatment to the Company and to the executive officers of
various payments and benefits. The Stock Option and Compensation Committee
intends to retain the deductibility of compensation pursuant to Section 162(m),
but reserves the right to provide non-deductible compensation if it determines
that such action is in the best interests of the Company and its stockholders.
 
MEMBERS OF THE STOCK OPTION AND COMPENSATION COMMITTEE FOR 1998 WERE:
 
     Robert W. Richards (Chairman), Claire M. Fagin and Ronald W. Moore. All of
the members of the compensation committee are non-employee directors.
 
PERFORMANCE GRAPH
 
     The Securities and Exchange Commission requires that the Company's total
return to its stockholders be compared to a relevant market index and a similar
industry index for the last five years or such shorter period of time as the
Company has been publicly traded. The Company became a publicly-traded company
on October 30, 1992, when its initial public offering commenced. The following
compares the total return to stockholders of (i) a $100 investment in the
Company's Common Stock, (ii) the Standard and Poor's 500 index, and (iii) a peer
group constructed by the Company for the period December 31, 1993 through
December 31, 1998. The three companies in the peer group, MGIC Investment
Corporation, a publicly-traded mortgage insurance company, Fannie Mae and the
Federal Home Loan Mortgage Corporation ("Freddie Mac") have been selected
because their core businesses involve residential mortgage lending.
 
     Total stockholder return is determined by dividing (i) the sum of the

CHANGE OF CONTROL AGREEMENTS
 
     See "CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS" for a description of
change of control agreements between the Company and its executive officers.
 
ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     Prior to the Company's initial public offering in October 1992 (the
"Offering"), the Company and CMAC were indirect subsidiaries of Reliance Group
Holdings, Inc. ("Reliance"). Mr. Wender, Chairman of the Board of the Company,
was Chairman of the Board and Chief Executive Officer of Commonwealth, an
indirect subsidiary of Reliance at that time.
 
     Concurrently with the Offering, Commonwealth purchased 800,000 shares of
the Company's $4.125 Preferred Stock (the "Preferred Stock") for an aggregate
purchase price of $40.0 million. On February 27, 1998, Commonwealth was acquired
by Land America Financial Group, Inc. and as successor to Commonwealth, now owns
the Preferred Stock. Dividends on the Preferred Stock are payable quarterly and
for the year ended December 31, 1998 totaled $3.3 million. The Preferred Stock
is redeemable at the option of the Company at $54.125 per share beginning August
15, 2002 and declining to $50.00 per share, in ten annual installments of 72,000
shares beginning in 2002 and the remaining 80,000 shares in 2012. In the event
that dividends on the Preferred Stock are in arrears and unpaid in an amount
equal to six quarterly dividends, the size of the Company's Board of Directors
will be increased by two to permit the holders of the Preferred Stock, voting
separately as a class, to elect two directors. The Company may not consummate
any Fundamental Transaction (defined as a merger, consolidation, sale of assets
or similar transaction on which the holders of the Common Stock are entitled to
vote) unless such transaction is approved by two-thirds of the outstanding
shares of the Preferred Stock. In connection with the sale of Preferred Stock,
the Company granted to Commonwealth certain rights to register the Preferred
Stock under the Securities Act of 1933, as amended.
 
     The Company has entered into change of control agreements with each of
Messrs. Filipps, Fischer, MacLeod, Quint, Carroll, Stevens and Yaruss. The
change of control agreements have initial terms of three years and upon
expiration of such period will be automatically extended for successive one-year
terms, unless terminated by either party. The change of control agreements
provide that in the event that, within two years after a "change in control" of
the Company or CMAC, the executive's employment is terminated (i) by the
 
                                       39
<PAGE>   41
 
Company for any reason other than (1) the executive's continued illness, injury
or incapacity for a period of twelve consecutive months or (2) for "cause",
which shall mean misappropriation of funds, habitual insobriety, substance
abuse, conviction of a crime involving moral turpitude, or gross negligence in
the performance of duties, which gross negligence has had a material adverse
effect on the business, operations, assets, properties or financial condition of
the Company and its subsidiaries taken as a whole, or (ii) by the executive in
the event of relocation or certain specified adverse changes in employment
status and compensation, the executive would be entitled to a lump-sum cash
payment equal to 2.0 times (1) the executive's then current annual base
compensation plus (2) the target bonus for the year in which a termination
occurs. Additionally, upon a change of control (as defined in the agreements),
all options not then vested would fully vest, and any restricted stock
previously granted to the executive which has not yet vested or become freely
transferable would become fully vested and freely transferable.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Basis of Presentation
 
     CMAC Investment Corporation (the "Company") was incorporated in December
1991 in order to hold the capital stock of Commonwealth Mortgage Assurance
Company ("CMAC"). In the fourth quarter of 1992, a merger among controlled
subsidiaries of CMAC was completed with the effect that the Company acquired all
of the outstanding stock of CMAC, and CMAC's sole stockholder, Commonwealth Land
Title Insurance Company ("Commonwealth"), then an indirect wholly owned
subsidiary of Reliance Group Holdings, Inc. ("Reliance"), acquired all of the
outstanding capital stock of the Company.
 
     In the fourth quarter of 1992, an initial public offering of the Company's
common stock (the "Offering") was completed. In this Offering, Commonwealth sold
all of the 7,000,000 shares owned by it, and the Company issued and sold
3,950,000 shares. In addition, the Company issued and sold 800,000 shares of
$4.125 Preferred Stock to Commonwealth. Aggregate proceeds to the Company from
the sale of common stock were approximately $67,200,000 and from the sale of
preferred stock were $40,000,000.
 
     CMAC and its subsidiaries provide private mortgage insurance and risk
management services to mortgage lending institutions located throughout the
United States. Consistent with the private mortgage insurance industry, CMAC's
highest state concentration of risk is in California. As of December 31, 1998,
California accounted for 18.3% of CMAC's total direct primary risk in force and
8.5% of CMAC's total direct pool risk in force. In addition, California
accounted for 18.5% of CMAC's direct new insurance written for the year ended
December 31, 1998. Private mortgage insurance protects lenders from
default-related losses on residential first mortgage loans made to home buyers
who make down payments of less than 20 percent of the purchase price and
facilitates the sale of these mortgages in the secondary market.
 
     The consolidated financial statements are prepared in accordance with
generally accepted accounting principles and include the accounts of all
subsidiaries. All material intercompany balances and transactions have been
eliminated in consolidation.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the Company to make estimates and
assumptions that affect the reported amounts of assets and liabilities as of the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
  Proposed Merger
 
     On November 22, 1998, the board of directors of the Company and the board
of directors of Amerin Corporation each approved an Agreement and Plan of Merger
pursuant to which the Company and Amerin will merge. The anticipated merger
calls for Amerin stockholders to receive 0.5333 shares of the Company's common
stock in a tax-free exchange for each share of Amerin common stock that they
own. The Company's stockholders will continue to own their existing shares after
the merger. Completion of the merger is subject to approval by the stockholders
of both companies and, pending this approval, the transaction is expected to
close in May 1999. The merger transaction will be accounted for on a pooling of
interests basis.
 
  Insurance Premiums
 
     Premiums written on an annual and multiyear basis are initially deferred as
unearned premiums and earned over the policy term, and premiums written on a
monthly basis are primarily earned as they are received. Annual premiums are
amortized on a monthly, straight-line basis. Multiyear premiums are amortized
over the terms of the contracts in accordance with the anticipated claim payment
pattern based on historical industry experience. Ceded premiums written are
initially set up as prepaid reinsurance and are amortized in accordance with
direct premiums earned.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Reserve for Losses
 
     The reserve for losses consists of the estimated cost of settling claims on
defaults reported and defaults that have occurred but have not been reported.
Consistent with generally accepted accounting principles and industry accounting
practices, the Company does not establish loss reserves for future claims on
insured loans that are not currently in default. In determining the liability
for unpaid losses related to reported outstanding defaults, the Company
establishes loss reserves on a case-by-case basis. The amount reserved for any
particular loan is dependent upon the status of the loan as reported by the
servicer of the insured loan as well as the economic condition and estimated
foreclosure period in the area in which the default exists. As the default
progresses closer to foreclosure, the amount of loss reserve for that particular
loan is increased, in stages, to approximately 100 percent of the Company's
exposure and that adjustment is included in current operations. The Company also
reserves for defaults that have occurred but have not been reported using
historical information on defaults not reported on a timely basis by lending
institutions. The estimates are continually reviewed and, as adjustments to
these liabilities become necessary, such adjustments are reflected in current
operations.
 
  Deferred Policy Acquisition Costs
 
     Costs associated with the acquisition of mortgage insurance business,
consisting of compensation, premium taxes and other policy issuance and
underwriting expenses, are initially deferred. The costs related to annual and
multiyear policies are amortized on a basis consistent with the recognition of
income while costs related to monthly policies are amortized over a period of
two years.
 
  Income Taxes
 
     Deferred income taxes are provided for the temporary difference between the
financial reporting basis and the tax basis of the Company's assets and
liabilities using enacted tax rates applicable to future years.
 
  Investments
 
     The Company is required to group its investment portfolio in three
categories: held to maturity, available for sale, and trading securities. Debt
securities for which the Company has the positive intent and ability to hold to
maturity are classified as held to maturity and reported at amortized cost. Debt
and equity securities purchased and held principally for the purpose of selling
them in the near term are classified as trading securities and reported at fair
value, with unrealized gains and losses included in earnings. The Company had no
trading securities in its portfolio at December 31, 1998 or 1997. All other
investments are classified as available for sale and are reported at fair value,
with unrealized gains and losses (net of tax) reported in a separate component
of stockholders' equity. Realized gains and losses are determined on a specific
identification method and are included in income.
 
  Fair Values of Financial Instruments
 
     The following methodology was used by the Company in estimating the fair
value disclosures for its financial instruments: fair values for fixed maturity
securities (including redeemable preferred stock) and equity securities are
based on quoted market prices, dealer quotes, and prices obtained from
independent pricing services. The carrying amounts reported on the balance sheet
for cash and short-term investments approximate their fair values.
 
  Accounting for Stock-Based Compensation
 
     The Company accounts for stock-based compensation in accordance with
Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for
Stock-Based Compensation". SFAS 123 requires

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
expanded disclosures of stock-based compensation arrangements with employees and
encourages, but does not require the recognition of compensation expense for the
fair value of stock options and other equity instruments granted as compensation
to employees. The Company has chosen to continue to account for stock-based
compensation using the intrinsic value method prescribed in Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees,"
("APB 25") and related interpretations. Accordingly, compensation cost for stock
options is measured as the excess, if any, of the quoted market price of the
Company's stock at the date of the grant over the amount an employee must pay to
acquire the stock.
 
  Net Income Per Share
 
     In March 1997, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 128, "Earnings Per Share". SFAS 128 requires the Company to disclose
both "basic" earnings per share and "diluted" earnings per share. Basic net
income per share is based on the weighted average number of common shares
outstanding, while diluted net income per share is based on the weighted average
number of common shares outstanding and common share equivalents that would
arise from the exercise of stock options. On October 15, 1996, the Board of
Directors authorized a stock split, payable December 2, 1996, in the form of a
dividend of one additional share of the Company's common stock for each share
owned by stockholders of record on November 7, 1996. The dividend was accounted
for as a two-for-one stock split and the par value of the common stock remained
at $.001 per share. Accordingly, all references to common per-share data have
been adjusted to give effect to the stock split. The calculation of the basic
and diluted net income per share, after giving effect to the stock split, was as
follows (in thousands, except per-share amounts):

  Comprehensive Income
 
     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," which requires an entity to present, as a component of comprehensive
income, the amounts from transactions and other events which are currently
excluded from the statement of income and are recorded directly to stockholders'
equity. The Company adopted SFAS No. 130 in 1998.
 
  Accounting Principles Issued and Not Yet Adopted
 
     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." The statement is effective for fiscal years
beginning after June 15, 1999 and will not be applied retroactively. The
statement establishes accounting and reporting standards for derivative
instruments and hedging activity and requires that all derivatives be measured
at fair value and recognized as either assets or

liabilities in the financial statements. The impact of the statement will depend
on the extent of derivatives and embedded derivatives at the date the statement
is adopted. The Company is currently evaluating the effect this statement might
have on the consolidated financial position or results of operations.
 
     In October 1998, the Accounting Standards Executive Committee of the
American Institute of Certified Public Accountants issued Statement of Position
98-7, "Deposit Accounting; Accounting for Insurance and Reinsurance Contracts
That Do Not Transfer Insurance Risk." This statement provides guidance on how to
apply the deposit method of accounting when it is required for insurance and
reinsurance contracts that do not transfer insurance risk. This statement is
effective for financial statements for fiscal years beginning after June 15,
1999. Management does not believe that the impact of applying this statement
will be material to the consolidated financial position or results of operations
of the Company when adopted.
 
  Reclassifications
 
     Certain items in the 1997 consolidated financial statements have been
reclassified to conform with the presentation in the 1998 consolidated financial
statements. Among the items reclassified is an adjustment relating to the
treatment of tax and loss bonds as more fully disclosed in note 6.

3.  REINSURANCE
 
     CMAC utilizes reinsurance to reduce net risk in force to meet regulatory
risk to capital requirements and to comply with the regulatory maximum policy
coverage percentage limitation of 25 percent. Although the use of reinsurance
does not discharge an insurer from its primary liability to the insured, the
reinsuring company assumes the related liability. Included in other assets are
amounts recoverable from reinsurers pertaining to unpaid claims, claims incurred
but not reported and unearned premiums (prepaid reinsurance). Prepaid
reinsurance premiums were $9,236,000 and $8,077,000 at December 31, 1998 and
1997, respectively.

     The 1998, 1997 and 1996 figures included $26,676,000, $18,847,000 and
$13,659,000 for premiums written and $27,126,000, $18,759,000 and $13,494,000
for premiums earned, respectively, for reinsurance ceded under variable quota
share treaties entered into in 1997, 1996, 1995 and 1994 covering the books of
business originated in those years. The 1998, 1997 and 1996 figures included
$3,614,000, $1,801,000 and $2,398,000 for premiums written and $2,042,000,
$1,211,000 and $1,072,000 for premiums earned, respectively, of reinsurance
ceded under an excess of loss reinsurance program that was entered into in 1992.
 
     Provisional losses recoverable of $32,718,000 and $31,325,000 for 1998 and
1997, respectively, represent amounts due under variable quota share treaties
entered into in 1997, 1996, 1995 and 1994, covering the books of business
originated in those years. The term of each treaty is ten years and is
non-cancelable by either party except under certain conditions. The treaties
also include underwriting year excess coverage in years four, seven and ten of
the treaty.
 
     Under the terms of the contract, the Company cedes premium to the reinsurer
based on 15% of the premiums received by the Company on the covered business.
The Company is entitled to receive a ceding commission ranging from 30% to 32%
of the premium paid under the treaty provided that certain loss ratios are not
exceeded. In return for the payment of premium, the Company receives variable
quota share loss relief at levels ranging from 7.5% to 15.0% based upon the loss
ratio on the covered business.
 
     In addition, the Company is entitled to receive, under the underwriting
year excess coverage, 8% of the ceded premium written under each treaty to the
extent that this amount is greater than the total amount received under the
variable quota share coverage on paid losses.
 
     Premiums are payable to the reinsurer on a quarterly basis net of ceding
commissions due and any losses calculated under the variable quota share
coverage. At the end of the fourth, seventh and tenth years of each treaty,
depending on the extent of losses recovered to date under the variable quota
share provisions of the treaty, the Company may recover amounts due under the
underwriting year excess coverage provisions of the treaty.
 
     The Company accounts for this reinsurance coverage under guidance provided
in EITF 93-6, "Accounting for Multiple-Year Retrospectively Rated Contracts by
Ceding and Assuming Enterprises". Under EITF 93-6, the Company recognizes an
asset for amounts due from the reinsurer based on experience to date under the
contract.

     For the years ended December 31, 1998, 1997 and 1996, the Company paid
$26,676,000, $18,847,000 and $13,659,000, respectively, less ceding commissions
of $9,076,000, $9,317,000 and $6,680,000 and recovered variable quota share
losses under the treaties of $4,600,000, $4,877,000 and $3,121,000,
respectively.
 
4.  UNPAID LOSSES AND LOSS ADJUSTMENT EXPENSES
 
     As described in note 1, the Company establishes reserves to provide for the
estimated costs of settling claims in respect of loans reported to be in default
and loans that are in default which have not yet been reported to the Company.
 
     The default and claim cycle on loans that the Company covers begins with
our receipt from the lender of notification of a default on an insured loan. Our
master policy with each lender requires them to inform the Company of an uncured
default on a mortgage loan within 75 days of the default. The incidence of
default is influenced by a number of factors, including change in borrower
income, unemployment, divorce and illness, the level of interest rates and
general borrower creditworthiness. Defaults that are not cured result in claims
to the Company. Borrowers may cure defaults by making all delinquent loan
payments or by selling the property and satisfying all amounts due under the
mortgage.
 
     Different regions of the country experience different default rates due to
varying economic conditions and each state has different rules regarding the
foreclosure process. These rules can impact the amount of time that it takes for
a default to reach foreclosure, so the Company has developed a reserving
methodology that takes these different time periods into account in calculating
the reserve.
 
     When a specific loan initially defaults, it is uncertain that the default
will result in a claim. It is the Company's experience that a significant
percentage of loans in default end up being cured. Therefore, by increasing the
reserve in stages as the foreclosure progresses, we are approximating the
estimated total loss for that particular claim. At any time during the
foreclosure process, until the lender takes title to the property, the borrower
may cure the default. Therefore, it is appropriate to increase the reserve in
stages as new insight and information is obtained. At the time of title
transfer, the Company has approximately 100% of the estimated total loss
reserved.

     As a result of changes in estimates of insured events in prior years, the
provision for losses and loss adjustment expenses (net of reinsurance recoveries
of $11,180,000, $6,504,000 and $2,913,000 in 1998, 1997 and 1996, respectively)
decreased by $11,518,000 in 1998 due primarily to lower than anticipated claim
payments as compared to the amounts reserved as a result of strong housing
prices, increased by $4,961,000 in 1997 due primarily to higher than anticipated
losses on certain "affordable housing" program loans insured in 1994 and 1995
and higher than anticipated losses in California and decreased by $3,404,000 in
1996 due primarily to lower than anticipated claim payments as compared to the
amounts reserved.
 
5.  REDEEMABLE PREFERRED STOCK
 
     Preferred stock is entitled to cumulative annual dividends of $4.125 per
share, payable quarterly in arrears. The preferred stock is redeemable at the
option of the Company at $54.125 per share on or after August 15, 2002, and
declining to $50.00 per share on or after August 15, 2005 (plus in each case
accumulated and unpaid dividends), or is subject to mandatory redemption at a
redemption price of $50.00 per share plus accumulated and unpaid dividends based
upon specified annual sinking fund requirements from 2002 to 2011.
 
6.  INCOME TAXES
 
     Deferred income taxes at the end of each period are determined by applying
enacted statutory tax rates applicable to the years in which the taxes are
expected to be paid or recovered. Deferred income taxes reflect the net tax
effects of temporary differences between the carrying amounts of assets and
liabilities for financial reporting purposes and the amounts for income tax
purposes. The effect on deferred taxes of a change in the tax rate is recognized
in earnings in the period that includes the enactment date.
 
     Provision for income taxes includes a net deferred tax provision in 1998,
1997 and 1996 of $26,654,000, $21,622,000 and $18,143,000, respectively. Of the
1998, 1997 and 1996 provisions, $25,547,000, $21,916,000

and $18,455,000, respectively, were due to a deduction related to the purchase
of U.S. government non-interest-bearing tax and loss bonds as allowed by federal
tax regulations, with the 1998, 1997 and 1996 purchase deduction offset by
$4,979,000, $4,060,000 and $2,636,000, respectively, of alternative minimum tax
adjustments. Prior to 1998, purchases of these tax and loss bonds were treated
as a reduction of the deferred tax liability. Beginning in 1998, these purchases
have been treated as prepaid federal income taxes and a reclassification has
been made to include this prepaid federal income tax in the balance sheet as an
asset and to reinstate the corresponding deferred tax liability. This change is
being made to more appropriately classify the deduction relating to the tax and
loss bond purchase as a deferred tax liability that will eventually be reversed.
The payment for the tax and loss bonds is essentially a prepayment of federal
income taxes that will become due at a later date. The change had the effect of
increasing both assets and liabilities by $103,700,000 in 1998 and $77,450,000
in 1997. All other amounts arose principally from differences in accounting for
deferred policy acquisition costs and insurance reserve tax adjustments required
as a result of the Tax Reform Act of 1986.
 
     The significant components of the Company's net deferred tax assets and
liabilities are summarized as follows (in thousands):

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
7.  STOCKHOLDERS' EQUITY AND DIVIDEND RESTRICTIONS
 
     The Company is a holding company whose principal source of income is
dividends from CMAC. The ability of CMAC to pay dividends on its common stock is
restricted by certain provisions of the insurance laws of the Commonwealth of
Pennsylvania, its state of domicile. The insurance laws of Pennsylvania
establish a test limiting the maximum amount of dividends that may be paid by an
insurer without prior approval by the Pennsylvania Insurance Commissioner. Under
such test, CMAC may pay dividends during any 12-month period in an amount equal
to the greater of (i) 10 percent of the preceding year-end statutory
policyholders' surplus or (ii) the preceding year's statutory net income. In
accordance with such restrictions, $105,264,000 would be available for dividends
in 1999. However, an amendment to the Pennsylvania statute, effective in 1994,
requires that dividends and other distributions be paid out of an insurer's
unassigned surplus. Because of the unique nature of the method of accounting for
contingency reserves, CMAC has negative unassigned surplus. Thus, prior approval
by the Pennsylvania Insurance Commissioner is required for CMAC to pay dividends
or make other distributions so long as CMAC has negative unassigned surplus. The
Pennsylvania Insurance Commissioner has approved all distributions by CMAC since
the passage of this amendment, and management has every expectation that the
Commissioner of Insurance will continue to approve such distributions in the
future, provided that the financial condition of CMAC does not materially
change.
 
     The State of California has a statute requiring mortgage insurers to pay
dividends or make other distributions out of unassigned surplus. CMAC and the
California Department of Insurance have reached an understanding under which
CMAC will be able to pay dividends or make other distributions to the Company,
provided that the financial condition of CMAC does not materially change.
 
     The Company and CMAC have entered into an agreement, pursuant to which the
Company has agreed to establish and, for as long as any shares of $4.125
Preferred Stock remain outstanding, maintain a reserve account in an amount
equal to three years of dividend payments on the outstanding shares of $4.125
Preferred Stock (currently $9,900,000), and not to pay dividends on the common
stock at any time when the amount in the reserve account is less than three
years of dividend payments on the shares of $4.125 Preferred Stock then
outstanding. This agreement between the Company and CMAC provides that the
holders of the $4.125 Preferred Stock are entitled to enforce the agreement's
provisions as if such holders were signatories to the agreement.
 
     The Company may not pay any dividends on shares of common stock unless the
Company has paid all accrued dividends on, and has complied with all sinking
fund and redemption obligations relating to, its outstanding shares of $4.125
Preferred Stock.
 
     CMAC's current excess of loss reinsurance arrangement prohibits the payment
of any dividend that would have the effect of reducing the total of its
statutory policyholders' surplus plus its contingency reserve below $85,000,000.
As of December 31, 1998, CMAC had statutory policyholders' surplus of
$149,281,000 and a contingency reserve of $467,856,000, for a total of
$617,137,000.
 
     CMAC, domiciled in Pennsylvania, prepares its statutory financial
statements in accordance with the accounting practices prescribed or permitted
by the Commonwealth of Pennsylvania Insurance Department. Prescribed statutory
accounting practices include a variety of publications of the National
Association of Insurance Commissioners ("NAIC") as well as state laws,
regulations and general administrative rules. Permitted statutory accounting
practices encompass all accounting practices not so prescribed.
 
     CMAC's statutory policyholders' surplus at December 31, 1998 and 1997 was
$149,281,000 and $148,087,000, respectively. CMAC's statutory net income for
1998, 1997 and 1996 was $105,264,000, $93,390,000 and $75,344,000, respectively.
The differences between the statutory net income and surplus and

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
the consolidated net income and equity presented on a GAAP basis represent
differences between GAAP and statutory accounting practices for the following
reasons:
 
     Under statutory accounting practices, mortgage guaranty insurance companies
are required to establish each year a contingency reserve equal to 50% of
premiums earned in such year. Such amount must be maintained in the contingency
reserve for 10 years after which time it is released to unassigned surplus.
Prior to 10 years, the contingency reserve may be reduced with regulatory
approval to the extent that losses in any calendar year exceed 35 percent of
earned premiums for such year. Under GAAP, the contingency reserve is not
required.
 
     Under statutory accounting practices, insurance policy acquisition costs
are charged against operations in the year incurred. Under GAAP, these costs are
deferred and amortized as the related premiums are earned.
 
     Statutory financial statements only include a provision for current income
taxes due, and purchases of tax and loss bonds are accounted for as investments.
GAAP financial statements provide for deferred income taxes, and purchases of
tax and loss bonds are recorded as payments of deferred income taxes.
 
     Under statutory accounting practices, fixed maturity investments are valued
at amortized cost. Under GAAP, those investments that CMAC does not have the
ability or intent to hold to maturity are considered to be available for sale
and are recorded at market value, with the unrealized gain or loss recognized,
net of tax, as an increase or decrease to shareholders' equity.
 
     Under statutory accounting practices, certain assets, designated as
non-admitted assets, are charged directly against statutory surplus. Such assets
are reflected on the GAAP financial statements.
 
     In March 1998, the National Association of Insurance Commissioners adopted
the Codification of Statutory Accounting Principles ("Codification"). The
Codification, which is intended to standardize regulatory accounting and
reporting for the insurance industry, is proposed to be effective January 1,
2001. However, statutory accounting principles will continue to be established
by individual state laws and permitted practices. The Commonwealth of
Pennsylvania will require adoption of the Codification for the preparation of
statutory financial statements effective January 1, 2001. The Company has not
finalized the quantification of the effects of Codification on its statutory
financial statements.
 
     In April, 1998, the Company's Board of Directors approved a stockholder
rights plan designed to help ensure that all stockholders receive fair value for
their shares of common stock in the event of any proposed takeover of the
Company and to guard against the use of partial tender offers or other coercive
tactics to gain control of the Company without offering fair value to the
stockholders.
 
8.  RELATED PARTY TRANSACTIONS
 
     In July 1992, the Company and Commonwealth entered into a sublease
agreement for office space, which provided for payments equal to Commonwealth's
cost, including base rent and a pass-through of certain building expenses. In
August 1993, substantially all of this subleased space was leased back to
Commonwealth at a market rental rate. The sublease expired May 31, 1996. The net
amount paid for the subleased space was $95,000 in 1996.
 
     Prior to the Offering, CMAC was included in the consolidated federal tax
return filed by Reliance, and CMAC was a party to a tax-sharing agreement with
Commonwealth. The tax-sharing agreement was terminated upon completion of the
Offering; however, CMAC has reimbursed Reliance for federal income taxes
attributable to CMAC's 1992 operations through the completion of the Offering as
though the tax-sharing agreement were still in effect. CMAC has agreed to
reimburse Reliance for federal income taxes, if any (together with any related
interest or penalties), attributable to CMAC for periods during which CMAC was a
member of Reliance's consolidated group. Reliance has agreed to limit the amount
of such reimbursement, if any, by CMAC to $1,853,000, the amount included in the
federal tax liability account on
                                      F-16

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
the Company's June 30, 1992 balance sheet (plus the amount of the tax benefit,
if any, obtained by the Company from making such reimbursement). In addition,
CMAC has agreed to reimburse Reliance for any future federal income taxes (plus
post-closing date interest) resulting from CMAC's operations while a member of
Reliance's consolidated group if CMAC could be benefited by a related adjustment
to CMAC's federal income taxes in an amount calculated as if CMAC were entitled
to such benefit. Reliance will reimburse CMAC for any future federal income
taxes resulting from CMAC's operations while a member of Reliance's consolidated
group which actually decrease Reliance's consolidated federal income taxes.
 
9.  STOCK-BASED COMPENSATION
 
     In November 1992, the Company's Board of Directors adopted the CMAC
Investment Corporation 1992 Stock Option Plan (the "Stock Option Plan"), which
provides for the granting of nonqualified stock options, either alone or
together with stock appreciation rights. Originally up to 500,000 shares were
subject to stock options. This amount was amended by a vote of the stockholders
to 900,000 in May 1993. These options may be granted to directors, officers, and
key employees of the Company at prices that are not less than 90 percent of fair
market value on the date the options are granted, although all options have been
granted with an exercise price equal to the fair value of the Company's stock at
the date of grant. Accordingly, no compensation expense has been recognized for
the Company's stock-based compensation plans. Each stock option is exercisable
for a period of ten years from the date of the grant and is subject to a vesting
schedule as approved by the Company's Stock Option and Compensation Committee.
In May 1995, the CMAC Investment Corporation Equity Compensation Plan was
instituted by a vote of the stockholders. This plan provides for the granting of
nonqualified stock options, under terms similar to those in the Stock Option
Plan, or other forms of equity-based compensation. The aggregate number of
shares that may be issued under this new plan was 1,100,000, which brought the
total number of shares subject to stock options or other forms of equity-based
compensation to 2,000,000. Effective with the stock split in December 1996, all
share totals within the plans were doubled, bringing the total number of shares
subject to stock options or other forms of equity-based compensation to
4,000,000.

     The Company applies APB 25 in accounting for its stock-based compensation
plans. Had compensation cost for the Company's stock option plans been
determined based upon the fair value at the grant date for awards under these
plans consistent with the methodology prescribed under SFAS 123, the Company's
net income and earnings per share would have been reduced by approximately
$1,879,000 ($0.08 per share), $1,460,000 ($0.06 per share) and $1,026,000 ($0.04
per share) in 1998, 1997 and 1996, respectively. The pro forma effect on net
income for 1998, 1997 and 1996 is not representative of the pro forma effect on
net income in future years, because it does not take into consideration pro
forma compensation expense related to grants made prior to 1995.
 
     The weighted average fair values of the stock options granted during 1997
and 1996 were $22.97 and $18.25, respectively. There were no stock options
granted during 1998. The fair value of each stock option grant is estimated on
the date of grant using the Black-Scholes option pricing model with the
following weighted average assumptions used for grants:

     In July 1997, the Company's Board of Directors adopted the 1997 CMAC
Investment Corporation Employee Stock Purchase Plan (the "ESPP") and shareholder
approval was granted during the Company's 1998 Annual Meeting. A total of
200,000 shares of the Company's authorized but unissued common stock has been
made available under the ESPP. The ESPP allows eligible employees to purchase
shares of the Company's stock at a discount of 15 percent of the
beginning-of-period or end-of-period (each period being the first and second six
calendar months) fair market value of the stock, whichever is lower. Eligibility
under the ESPP is determined based on standard weekly work hours and tenure with
the Company and eligible employees are limited to a maximum contribution of $400
per payroll period toward the purchase of the Company's stock. Under the ESPP,
the Company sold 1,900 shares in 1998. The Company applies APB 25 in accounting
for the ESPP. The pro forma effect on the Company's net income and earnings per
share had compensation cost been determined under SFAS 123 was deemed immaterial
in 1998.
 
10.  BENEFIT PLANS
 
     In 1997, the FASB issued SFAS No. 132, "Employer's Disclosures about
Pensions and Other Postretirement Benefits." This statement, which is effective
for periods beginning after December 15, 1997, modifies previous disclosure
requirements. This statement does not impact the Company's balance sheets,
statements of income or statements of cash flows. The Company adopted SFAS No.
132 in 1998.
 
     The Company maintains a noncontributory defined benefit pension plan
covering substantially all full-time employees that is similar to the pension
plan of Commonwealth that covered all of the Company's employees prior to the
Offering. The new plan did not require an asset transfer, and all eligible
Company employees are entitled to benefits from both plans. The projected
benefit obligation that arose when the new plan was consummated is approximately
$675,000. This obligation is being amortized into pension expense over the
longer of the expected remaining service life of eligible employees or 15 years.
Retirement benefits are a function of the years of service and the level of
compensation. Assets of the plan consist primarily of balanced mutual funds.
 
     The Company also provides a nonqualified deferred compensation plan
covering certain key executives designated by the Board of Directors. Under this
plan, participants are eligible to receive benefits in addition to those paid
under the defined benefit pension plan if their base compensation is in excess
of the current IRS compensation limitation for the defined benefit pension plan.
Retirement benefits under the nonqualified plan are a function of the years of
service and the level of compensation and are reduced by any benefits paid under
the defined benefit plan.
 
     In addition to providing pension benefits, the Company will provide certain

     Assumptions used to determine net pension and net periodic postretirement
benefit costs are as follows:

Weighted average assumptions as of December 31:
  Discount rate..................................  6.75%   7.25%   7.50%   6.75%   7.25%   7.75%
  Expected return on plan assets.................  8.50%   8.50%   8.50%   8.50%   8.50%   8.50%
  Rate of compensation increase..................  4.00%   6.00%   6.00%     --      --      --
</TABLE>
 
     Due to the nature of the postretirement welfare plan, no increase is
assumed in the Company's obligation due to any increases in the per capita cost
of covered health care benefits.
 
     In addition to the defined benefit plan, the nonqualified deferred
compensation plan, and the postretirement benefit plan, the Company also
maintains a Savings Incentive Plan, which covers substantially all full-time
employees and all part-time employees employed for a minimum of 90 consecutive
days. Participants can contribute up to 15 percent of their base earnings as
pre-tax contributions. The Company will match at least 25 percent of the first 5
percent of base earnings contributed in any given year. These matching funds are
subject to certain vesting requirements. The expense to the Company for matching
funds for the years ended December 31, 1998, 1997 and 1996 was $641,000,
$544,000 and $474,000, respectively.
 
11.  COMMITMENTS AND CONTINGENCIES
 
     CMAC is involved in certain litigation arising in the normal course of its
business. CMAC is contesting the allegations in each pending action and
believes, based on current knowledge and consultation with counsel, that the
outcome of such litigation will not have a material adverse effect on the
Company's consolidated financial position or results of operations.
 
     CMAC utilized its underwriting skills to provide an outsource contract
underwriting service to its customers. CMAC often gives recourse to its
customers on loans it underwrites for compliance. If the loan does not meet
agreed upon guidelines and is not salable in the secondary market for that
reason, CMAC agrees to remedy the situation either by placing mortgage insurance
coverage on the loan or by purchasing the loan. During 1998, less than 1 percent
of all loans were subject to these remedies and the costs associated with these
remedies were negligible.
 
     The Company and CMAC shared a $5,000,000 discretionary line of credit to be
used for general corporate purposes. There were no draws against this line of
credit during 1997, and it was revoked in early 1998.
 
     The Company leases office space for use in its underwriting, sales, loan
workout and administrative support operations. Net rental expense in connection
with these leases totaled $2,154,000, $1,990,000 and $1,468,000 in 1998, 1997
and 1996, respectively. The commitment for noncancelable operating leases in
future years is as follows (in thousands):

                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors and Stockholders
CMAC Investment Corporation
Philadelphia, Pennsylvania
 
     We have audited the accompanying consolidated balance sheets of CMAC
Investment Corporation and subsidiaries (the "Company") as of December 31, 1998
and 1997, and the related consolidated statements of income, changes in common
stockholders' equity and comprehensive income and cash flows for each of the
three years in the period ended December 31, 1998. Our audits also included the
financial statement schedules listed in the Index at Item 14. These financial
statements and financial statement schedules are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements and financial statement schedules based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of CMAC Investment Corporation and
subsidiaries at December 31, 1998 and 1997, and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1998 in conformity with generally accepted accounting principles. Also, in
our opinion, such financial statement schedules, when considered in relation to
the basic consolidated financial statements taken as a whole, present fairly in
all material respects the information set forth therein.

                              PARENT COMPANY ONLY
                              SUPPLEMENTARY NOTES
 
NOTE A
 
     The accompanying Parent Company financial statements should be read in
conjunction with the Consolidated Financial Statements and Notes to Consolidated
Financial Statements appearing on pages F-1 through F-22 of the CMAC Investment
Corporation 1998 Form 10-K.
 
NOTE B
 
     CMAC Investment Corporation (the "Company") was incorporated in December,
1991 in order to hold the capital stock of Commonwealth Mortgage Assurance
Company ("CMAC"). In the fourth quarter of 1992, a merger among controlled
subsidiaries of CMAC was consummated with the effect that the Company acquired
all of the outstanding stock of CMAC, and CMAC's sole stockholder, Commonwealth
Land Title Insurance Company ("Commonwealth"), then an indirect wholly owned
subsidiary of Reliance Group Holdings, Inc., acquired all of the outstanding
capital stock of the Company.
 
     In the fourth quarter of 1992, the initial public offering of the Company's
common stock (the "Offering") was consummated. In the Offering, Commonwealth
sold all of the 7,000,000 shares owned by it, and the Company issued and sold
3,950,000 shares. In addition, the Company issued and sold 800,000 shares of
$4.125 Preferred Stock to Commonwealth. Aggregate proceeds to the Company from
the sale of common stock were approximately $67,200,000 and from the sale of
preferred stock were $40,000,000.
 
     The preferred stock, issued in connection with the Offering, is entitled to
cumulative annual dividends of $4.125 per share, payable quarterly in arrears.
The preferred stock is redeemable at the option of the Company at $54.125 per
share on or after August 15, 2002, and declining to $50.00 per share on or after
August 15, 2005 (plus in each case accumulated and unpaid dividends), or is
subject to mandatory redemption at a redemption price of $50.00 per share plus
accumulated and unpaid dividends based upon specified annual sinking fund
requirements from 2002 to 2011.
 
     The Company is a holding company whose principal source of income is
dividends from CMAC. The ability of CMAC to pay dividends on its common stock is
restricted by certain provisions of the insurance laws of the Commonwealth of
Pennsylvania, its state of domicile. The insurance laws of Pennsylvania
establish a test limiting the maximum amount of dividends which may be paid by
an insurer without prior approval by the Pennsylvania Insurance Commissioner.
Under such test, CMAC may pay dividends during any 12-month period in an amount
equal to the greater of (i) 10% of the preceding year-end statutory
policyholders' surplus or (ii) the preceding year's statutory net income. In
accordance with such restrictions, $105,264,000 would be available for dividends
in 1999. However, an amendment to the Pennsylvania statute, effective in 1994,
requires that dividends and other distributions be paid out of an insurer's
unassigned surplus. Because of the unique nature of the method of accounting for
contingency reserves, CMAC has negative unassigned surplus. Thus, prior approval
by the Pennsylvania Insurance Commissioner is required for CMAC to pay dividends
or make other distributions so long as CMAC has negative unassigned surplus. The
Pennsylvania Insurance Commissioner has approved all distributions by CMAC since
the passage of this amendment and management has every expectation that the
Commissioner of Insurance will continue to approve such distributions in the
future, provided that the financial condition of CMAC does not materially
change.
 
     The State of California has a statute requiring mortgage insurers to pay
dividends or make other distributions out of unassigned surplus. CMAC and the
California Department of Insurance have reached an understanding under which
CMAC will be able to pay dividends or make other distributions to the Company
provided that the financial condition of CMAC does not materially change.
 
     In addition, CMAC's current excess of loss reinsurance arrangement
prohibits the payment of any dividend which would have the effect of reducing
the total of its statutory policyholders' surplus plus its
                                       S-5

contingency reserve below $85,000,000. As of December 31, 1998, CMAC had
statutory policyholders' surplus of $149,281,000 and a contingency reserve of
$467,856,000, for a total of $617,137,000.
 
     The Company and CMAC have entered into an agreement pursuant to which the
Company has agreed to establish and, for so long as any shares of $4.125
Preferred Stock remain outstanding, maintain a reserve account in an amount
equal to three years of dividend payments on the outstanding shares of $4.125
Preferred Stock (currently $9.9 million), and not to pay dividends on the common
stock at any time when the amount in the reserve account is less than three
years of dividend payments on the shares of $4.125 Preferred Stock then
outstanding. This agreement between the Company and CMAC provides that the
holders of the $4.125 Preferred Stock are entitled to enforce the agreement's
provisions as if such holders were signatories to the agreement.
 
     The Company may not pay any dividends on shares of common stock unless the
Company has paid all accrued dividends on and has complied with all sinking fund
and redemption obligations relating to its outstanding shares of $4.125
Preferred Stock.
 
NOTE C
 
     On October 15, 1996, the Board of Directors authorized a stock split, paid
on December 2, 1996, in the form of a dividend of one additional share of the
Company's common stock for each share owned by stockholders of record on
November 7, 1996. The dividend was accounted for as a two-for-one stock split
and par value remained at $.001 per share.
 
     Accordingly, all references to common share and per-share data have been
adjusted to give effect to the stock split.
 
NOTE D
 
     On November 22, 1998, the Board of Directors of the Company and the Board
of Directors of Amerin Corporation each approved an Agreement and Plan of Merger
pursuant to which the Company and Amerin will merge. The anticipated merger
calls for Amerin stockholders to receive 0.5333 shares of the Company's common
stock in a tax-free exchange for each share of Amerin common stock that they
own. The Company's stockholders will continue to own their existing shares after
the merger. Completion of the merger is subject to approval by the stockholders
of both companies and, pending this approval, the transaction is expected to
close in May 1999. The merger transaction will be accounted for on a pooling of
interests basis.

                                    AGREEMENT

THIS AGREEMENT made and entered into this 6th day of February, 1998 by and
between CMAC INVESTMENT CORPORATION, a corporation organized and existing under
the laws of the state of Delaware (hereinafter referred to as the "Company") and
SCOTT C. STEVENS (hereinafter referred to as the "Employee").

WHEREAS, the Employee is presently employed by the Company as its VICE PRESIDENT
FOR HUMAN RESOURCES AND ADMINISTRATION; and

WHEREAS, the Board of Directors of the Company (the "Board") recognizes that, as
is the case with many publicly-held corporations, the possibility of a change in
control of the Company exists and that such possibility, and the uncertainty and
questions it may raise among management, may result in the departure or
distraction of key management personnel to the detriment of the Company; and

WHEREAS, the Board has determined that appropriate steps should be taken to
reinforce and encourage the continued attention and dedication of key members of
the Company's management to their assigned duties without distraction in the
face of potentially disturbing circumstances arising from the possibility of a
change in control of the Company; and

WHEREAS, in order to induce the Employee to remain in the employ of the Company,
the Company agrees that the Employee shall receive the compensation set forth in
this Agreement as a cushion against the financial and career impact on the
Employee in the event that Employee's employment with the Company is terminated
subsequent to a "Change of Control" (as that term is defined in Section 1
hereof).

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and
agreements hereinafter set forth and intending to be legally bound hereby, the
parties hereto agree as follows:

1. DEFINITIONS. When used in this Agreement, the following terms shall have the
specific meanings shown in this Section unless the context of any provision of
this Agreement clearly requires otherwise:

     (a) "Affiliate" and "Associate" shall have the respective meanings ascribed
to such terms in Rule 12b-2 of the General Rules and Regulations under the
Securities Exchange Act of 1934, as amended (the "Exchange Act").

     (b) "Beneficial Owner" of any securities shall mean:

          (i) that such Person or any of such Person's Affiliates or Associates,
directly or indirectly, has the right to acquire (whether such right is
exercisable immediately or only after the passage of time) pursuant to any
agreement, arrangement or understanding (whether or not in writing) or upon the
exercise of conversion rights, exchange rights, rights, warrants or options, or
<PAGE>   2
otherwise; provided, however, that a Person shall not be deemed the "Beneficial
Owner" of securities tendered pursuant to a tender or exchange offer made by
such Person or any of such Person's Affiliates or Associates until such tendered
securities are accepted for payment, purchase or exchange;

          (ii) that such Person or any of such Person's Affiliates or
Associates, directly or indirectly, has the right to vote or dispose of or has
"beneficial ownership" of (as determined pursuant to Rule 13d-3 of the General
Rules and Regulations under the Exchange Act), including without limitation,
pursuant to any agreement, arrangement or understanding (whether or not in
writing); provided, however, that a Person shall not be deemed the "Beneficial
Owner" of any security under this subsection (ii) as a result of an oral or
written agreement, arrangement or understanding to vote such security if such
agreement, arrangement or understanding (A) arises solely from a revocable proxy
given in response to a public proxy or consent solicitation made pursuant to, an
in accordance with, the applicable provisions of the General Rules and
Regulations under the Exchange Act, and (B) is not then reportable by such
Person on Schedule 13D under the Exchange Act (or any comparable successor
report); or

          (iii) where voting securities are beneficially owned, directly or
indirectly, by any other Person (or any Affiliate or Associate thereof) with
which such Person (or any of such Person's Affiliates or Associates) has any
agreement, arrangement or understanding (whether or not in writing) for the
purpose of acquiring, holding, voting (except pursuant to a revocable proxy
described in the proviso to subsection (ii) above) or disposing of any voting
securities of the Company;

provided, however, that nothing in this subsection (b) shall cause a Person
engaged in business as an underwriter of securities to be the "Beneficial Owner"
of any securities acquired through such Person's participation in good faith in
a firm commitment underwriting until expiration of forty (40) days after the
date of such acquisition.

     (c) "Change of Control" shall be deemed to have taken place if (i) any
Person (except for the Employee or his family, the Company or any employee
benefit plan of the Company or of any Affiliate, any Person or entity organized,
appointed or established by the Company for or pursuant to the terms of any such
employee benefit plan), together with all Affiliates and Associates of such
Person, shall become the Beneficial Owner in the aggregate of 20% or more of the
shares of the Company then outstanding and entitled to vote for directors
generally, (ii) any Person (except the Employee and his family), together with
all Affiliates and Associates of such Person purchases substantially all of the
assets of the Company, or (iii) during any twenty-four (24) month period,
individuals who at the beginning of such period constituted the Board cease for
any reason to constitute a majority thereof, unless the election, or the
nomination for election by the Company's stockholders, of at least seventy-five
percent (75%) of the directors who were not directors at the beginning of such
period was approved by a vote of at least seventy-five percent (75%) of the
directors in office at the time of such election or nomination who were
directors at the beginning of such period.


                                                                               2
<PAGE>   3
     (d) "Person" shall mean any individual, firm, corporation, partnership or
other entity.

     (e) "Subsidiary" shall have the meaning ascribed to such term in Rule 12b-2
of the General Rules and Regulations under the Exchange Act.

     (f) "Termination Date" shall mean the date of receipt of the Notice of
Termination described in Section 2 hereof or any later date specified therein,
as the case may be.

     (g) "Termination of Employment" shall mean the termination of the
Employee's actual employment relationship with the Company.

     (h) "Termination following a Change of Control" shall mean a Termination of
Employment within two years after a Change of Control either:

          (i) initiated by the Company for any reason other than (a) the
Employee's continuous illness, injury or incapacity for a period of twelve
consecutive months or (b) for "cause", which shall mean misappropriation of
funds, habitual insobriety, substance abuse, conviction of a crime involving
moral turpitude, or gross negligence in the performance of duties, which gross
negligence has had a material adverse effect on the business, operations,
assets, properties or financial condition of the Company and its Subsidiaries
taken as a whole; or

          (ii) initiated by the Employee upon the occurrence of one or more of
the following:

               (A) any failure of the Company to comply with and satisfy any of
the conditions of this Agreement;

               (B) any change resulting in a significant reduction by the
Company of the authority, duties or responsibilities of the Employee;

               (C) any removal by the Company of the Employee from the
employment grade, compensation level or officer positions which the Employee
holds as of the effective date hereof, except in connection with promotions to a
higher office;

               (D) the requirement that the Employee undertake business travel
(or commuting in excess of fifty miles each way) to an extent substantially
greater than is reasonable and customary for the position the Employee holds.

2. NOTICE OF TERMINATION. Any Termination following a Change of Control shall be
communicated by a Notice of Termination to the other party hereto given in
accordance with Section 14 hereof. For purposes of this Agreement, a "Notice of
Termination" means a written notice which (i) indicates the specific termination
provision in this Agreement relied upon, (ii) briefly summarizes the facts and
circumstances deemed to provide a basis for termination of the Employee's
employment under the provision so indicated, and (iii) if the Termination Date
is other than the date of receipt


                                                                               3
<PAGE>   4
of such notice, specifies the Termination Date (which date shall not be more
than fifteen days after the giving of such notice).

3. BENEFITS UPON CHANGE OF CONTROL.

     (a) In the event of a Change of Control (i) any stock options previously
granted to the Employee under any Company stock option or equity compensation
plan which have not yet vested shall become vested, and (ii) any restricted
stock previously granted to the Employee under any Company equity compensation
plan which has not yet vested or become freely transferable shall become vested
and freely transferable.

     (b) In the event of the Employee's Termination following a Change of
Control the Company shall pay to the Employee, within fifteen days after the
Termination Date, an amount in cash equal to 2.0 times (i) the Employee's then
current annual base compensation, plus (ii) the Employee's then current target
bonus eligibility.

     (c) In the event of the Employee's Termination following a Change of
Control, the Employee shall be entitled to continued participation in the
Company's life, disability, accident and health insurance plans for a period not
to exceed thirty-six (36) months following the termination.

4. OTHER PAYMENTS. The payment due under Section 3 hereof shall be in addition
to and not in lieu of any payments or benefits due to the Employee under any
other plan, policy or program of the Company except that no payments shall be
due to the Employee under the Company's then current severance pay plan for
employees, if any.

5. ESTABLISHMENT OF TRUST. The Company has or will establish an irrevocable
trust fund (hereinafter referred to as the "Trust Fund") pursuant to a trust
agreement to hold assets contributed to satisfy its obligations under this
Agreement. Funding of such trust fund shall be subject to the Company's
discretion, as set forth in the trust agreement establishing the Trust Fund.
Notwithstanding the foregoing:

     (a) Upon a Change of Control of the Company, the Chief Financial Officer of
the Company, or his authorized representative (hereinafter referred to
collectively as the "Treasurer"), shall immediately remit to the Trustee of the
Trust Fund as a contribution to the applicable trust established as part of the
Trust Fund for the benefit of the Employee the amount due under this Agreement
and not yet contributed to the Trustee as well as an amount estimated to be
sufficient to pay all fees and expenses that may thereafter become due. The
Trustee shall be under no duty to determine the sufficiency, or to enforce the
making, of such contributions.

     (b) In the event that the Chairman of the Board determines that a Change of
Control of the Company is imminent, the Treasurer shall make the payments to the
Trustee specified in paragraph (i) above. If a Change of Control of the Company
shall not have occurred within ninety (90) days of the contribution made
pursuant to this Section 5 and the Board adopts a resolution to the effect that,
for purposes of this Agreement, a Change of Control of the Company is not
imminent,


                                                                               4
<PAGE>   5
any amounts added to the Trust Fund pursuant to this Section, together with any
earnings thereon, shall be paid by the Trustee to the Company.

6. ENFORCEMENT.

     (a) In the event that the Company shall fail or refuse to make payment of
any amounts due the Employee under Sections 3 and 4 hereof within the respective
time periods provided therein, the Company shall pay to the Employee, in
addition to the payment of any other sums provided in this Agreement, interest,
compounded daily, on any amount remaining unpaid from the date payment is
required under Section 3 and 4, as appropriate, until paid to the Employee, at
the rate from time to time announced by PNC Bank, or its successor, as its
"prime rate" plus 2%, each change in such rate to take effect on the effective
date of the change in such prime rate.

     (b) It is the intent of the parties that the Employee not be required to
incur any expenses associated with the enforcement of his rights under this
Agreement by arbitration, litigation or other legal action because the cost and
expense thereof would substantially detract from the benefits intended to be
extended to the Employee hereunder. Accordingly, the Company shall pay the
Employee on demand the amount necessary to reimburse the Employee in full for
all expenses (including attorney's fees and legal expenses) incurred by the
Employee in enforcing any of the obligations of the Company under this
Agreement.

7. NO MITIGATION. The Employee shall not be required to mitigate the amount of
any payment or benefit provided for in this Agreement by seeking other
employment or otherwise, nor shall the amount of any payment or benefit provided
for herein be reduced by any compensation earned by other employment or
otherwise.

8. NON-EXCLUSIVITY OF RIGHTS. Nothing in this Agreement shall prevent or limit
the Employee's continuing or future participation in or rights under any
benefit, bonus, incentive or other plan or program provided by the Company or
any of its Subsidiaries or Affiliates and for which the Employee may qualify;
provided, however, that with respect to a Termination following a Change of
Control, the Employee hereby waives the Employee's right to receive any payments
under any severance pay plan or similar program applicable to other employees of
the Company, and agrees to accept the payment provided in Section 3(b) above in
lieu of any other severance pay plan or similar program.

9. NO SET-OFF. The Company's obligation to make the payments provided for in
this Agreement and otherwise to perform its obligations hereunder shall not be
affected by any circumstances, including, without limitation, any set-off,
counterclaim, recoupment, defense or other right which the Company may have
against the Employee or others.

10. TAXES. Any payment required under this Agreement shall be subject to all
requirements of law with regard to the withholding of taxes, filing, making of
reports and the like, and the Company shall use its best efforts to satisfy
promptly all such requirements.


                                                                               5
<PAGE>   6
11. ADJUSTMENT FOR TAXES. In the event that either the Company's independent
public accountants or the Internal Revenue Service determine that any payment,
coverage, benefit or benefit acceleration provided to the Employee, whether
specifically provided for in this Agreement or otherwise, is subject to the
excise tax imposed by Section 4999 (or any successor provision) ("Section 4999")
of the Code, the Company, within thirty (30) days thereafter, shall pay to the
Executive, in addition to any other payment, coverage or benefit due and owing
hereunder, an amount determined by multiplying the rate of excise tax then
imposed by Section 4999 by the amount of the "excess parachute payment" received
by the Executive (determined without regard to any payments made to the
Executive pursuant to this paragraph) and dividing the product so obtained by
the amount obtained by subtracting the aggregate local, estate and Federal
income tax rate applicable to the receipt by the Employee of the "excess
parachute payment" (taking into account the deductibility for Federal income tax
purposes of the payment of state and local income taxes thereon) from the amount
obtained by subtracting from 1.00 the rate of excise tax then imposed by Section
4999 of the Code, it being the Company's intention that the Employee's net after
tax position be identical to that which would have obtained had Sections 280G
and 4999 not been a part of the Code.

12. TERM OF AGREEMENT. The term of this Agreement shall be for 3 years from the
date hereof and shall be automatically renewed for successive one-year periods
unless the Company notifies the Employee in writing that this Agreement will not
be renewed at least sixty (60) days prior to the end of the current term;
provided, however, that (i) after a Change of Control during the term of this
Agreement, this Agreement shall remain in effect until all of the obligations of
the parties hereunder are satisfied or have expired, and (ii) this Agreement
shall terminate if, prior to a Change of Control, the employment of the Employee
with the Company or any of its Subsidiaries, as the case may be, shall terminate
for any reason, or if the Employee shall cease to be an Employee.

13. SUCCESSOR COMPANY. The Company shall require any successor or successors
(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business and/or assets of the Company, by
agreement in form and substance satisfactory to the Employee, to acknowledge
expressly that this Agreement is binding upon and enforceable against the
Company in accordance with the terms hereof, and to become jointly and severally
obligated with the Company to perform this Agreement in the same manner and to
the same extent that the Company would be required to perform if no such
succession or successions had taken place. Failure of the Company to obtain such
agreement prior to the effectiveness of any such succession shall be a breach of
this Agreement. As used in this Agreement, the Company shall mean the Company as
hereinbefore defined and any successor or successors to its business and/or
assets, jointly and severally.

14. NOTICE. All notices and other communications required or permitted hereunder
or necessary or convenient herewith shall be in writing and shall be delivered
personally or mailed by registered or certified mail, return receipt requested,
or by overnight express courier service, as follows:

If to the Company, to:


                                                                               6

may be, shall designate by notice to the other party hereto in the manner
specified in this Section 14; provided, however, that if no such notice is given

Company or to any successor pursuant to Section 13 hereof shall be deemed
sufficient for the purposes hereof. Any such notice shall be deemed delivered
and effective when received in the case of personal delivery; five days after
deposit, postage prepaid, with the U.S. Postal Service in the case of registered
or certified mail; or on the next business day in the case of an overnight
express courier service.

15. GOVERNING LAW. This Agreement shall be governed by and construed by and

entire understanding between the parties hereto with respect to the subject
matter hereof and cannot be changed, modified, extended or terminated except
upon written amendment executed by the Employee and approved by the Board and
executed on the Company's behalf by a duly authorized officer. The provisions of
this Agreement may provide for payments to the Employee under certain
compensation or bonus plans under circumstances where such plans would not
provide for the payment thereof. It is the specific intention of the parties
that the provisions of this Agreement shall supersede any provisions to the
contrary in such plans, and such plans shall be deemed to have been amended to
correspond with this Agreement without further action by the Company or the
Board.

     (b) Nothing in this Agreement shall be construed as giving the Employee any
right to be retained in the employ of the Company.

     (c) All of the terms and provisions of this Agreement shall be binding upon
and inure to the benefit of and be enforceable by the respective heirs,
representatives, successors and assigns of the parties hereto, except that the
duties and responsibilities of the Employee and the Company hereunder shall not
be assignable in whole or in part by the Company.


                                                                               7

17. SEVERABILITY. If any provision of this Agreement or application thereof to
anyone or under any circumstances shall be determined to be invalid or
unenforceable, such invalidity or unenforceability shall not affect any other
provisions or applications of this Agreement which can be given effect without
the invalid or unenforceable provision or application.

18. REMEDIES CUMULATIVE; NO WAIVER. No right conferred upon the Employee by this
Agreement is intended to be exclusive of any other right or remedy, and each and
every such right or remedy shall be cumulative and shall be in addition to any
other right or remedy given hereunder or now or hereafter existing at law or in
equity. No delay or omission by the Employee in exercising any right, remedy or
power hereunder or existing at law or in equity shall be construed as a waiver
thereof, including, without limitation, any delay by the Employee in delivering
a Notice of Termination pursuant to Section 2 hereof after an event has occurred
which would, if the Employee had resigned, have constituted a Termination
following a Change of Control pursuant to this Agreement.

19. MISCELLANEOUS. All section headings are for convenience only. This Agreement
may be executed in several counterparts, each of which is an original. It shall
not be necessary in making proof of this Agreement or any counterpart hereof to
produce or account for any of the other counterparts.

IN WITNESS WHEREOF, the undersigned, intending to be legally bound, have
executed this Agreement as of the date first above written.

                           CMAC INVESTMENT CORPORATION
                            EQUITY COMPENSATION PLAN
                           (AMENDED AND RESTATED AS OF
                                 April 13, 1999)

            The purpose of the Equity Compensation Plan (the "Plan") of CMAC
Investment Corporation (the "Company") is to promote the interests of the
Company by providing incentives to (i) designated officers and other employees
of the Company or an Affiliate (as defined herein), and (ii) non-employee
members of the Board of Directors of the Company (the "Board"), to encourage
them to acquire a proprietary interest, or to increase their proprietary
interest, in the Company. The Company believes that the Plan will cause
participants to contribute materially to the growth of the Company, thereby
benefitting the Company's stockholders. For purposes of the Plan, the term
"Affiliate" shall mean a person that directly, or indirectly through one or more
intermediaries, controls, or is controlled by, the Company; and the terms
"Parent Corporation" and "Subsidiary Corporation" shall have the meanings set
forth in subsections (e) and (f) of Section 424 of the Internal Revenue Code of
1986, as amended (the "Code").

1.    Administration

      The Plan shall be administered and interpreted by a committee of the Board
(the "Committee"); provided, however, that grant decisions made hereunder shall
be made by at least two persons, each of whom may be (i) "outside directors" as
defined under Section 162(m) of the Internal Revenue Code, and (ii)
"non-employee directors" as defined under Rule 16b-3 of the Securities Exchange
Act of 1934. The Board may appoint a subcommittee for this purpose, in which
case references herein to the "Committee": shall mean the subcommittee as
appropriate. The Committee shall have the sole authority to determine (i) who is
eligible to receive Grants (as defined in Section 2 below) under the Plan, (ii)
the type, size and terms of each Grant under the Plan (subject to Section 4
below), (iii) the time when each Grant will be made and the duration of any
exercise or restriction period; (iv) any restrictions on resale applicable to
the shares to be issued or transferred pursuant to the Grant; and (v) any other
matters arising under the Plan. The Committee may, in its discretion or in
accordance with a directive from the Board, waive any provisions of any Grant,
provided such waiver is not inconsistent with the terms of this Plan as then in
effect. The Committee may, if it so desires, base any of the foregoing
determinations upon the recommendations of management of the Company. A majority
of the Committee shall constitute a quorum thereof, and the actions of a
majority of the Committee at a meeting at which a quorum is present, or actions
unanimously approved in writing by all members of the Committee, shall be
actions of the Committee. The Committee shall have full power and authority to
administer and interpret the Plan and to adopt or amend such rules, regulations,
agreements and instruments as it may deem appropriate for the proper
administration of the Plan. The Committee's interpretations of the Plan and all
determinations made by the Committee pursuant to the powers vested in it
hereunder shall be conclusive and binding on all persons having any interests in
the Plan or in any Grants under the Plan. No person acting under this
<PAGE>   2
subsection shall be held liable for any action or determination made with
respect to the Plan or any Grant under the Plan, except for the willful
misconduct or gross negligence of such person.

            Incentives under the Plan shall consist of Incentive Stock Options
(as defined in Section 5(b) below), Nonqualified Stock Options (as defined in
Section 5(b) below), Restricted Stock Grants (as defined in Section 6 below),
SARs (as defined in Section 7 below), and Phantom Stock (as defined in Section 8
below) (hereinafter collectively referred to as "Grants"). All Grants shall be
subject to the terms and conditions set forth herein and to such other terms and
conditions of any nature as the Committee deems appropriate and specifies in
writing to the participant (the "Grant Letter"), as long as they are not
inconsistent with the Plan. The Committee shall approve the form and provisions
of each Grant Letter. Grants under any section of the Plan need not be uniform
as among the participants receiving the same type of Grant, and Grants under two
or more sections of the Plan may be combined in one Grant Letter.

3.    Shares Subject to the Plan

            (a) The aggregate number of shares of the Common Stock, par value
$0.001 ("Common Stock"), of the Company that may be issued or transferred under
the Plan is 2,200,000, subject to adjustment pursuant to Section 3(b) below. The
maximum number of shares of Common Stock for which any Grantee may be granted
options (and related stock appreciation rights) under the Plan is limited to
75,000 for any calendar year, subject to adjustment pursuant to Section 3(b)
below. The shares may be authorized but unissued shares or reacquired shares. If
and to the extent that options or SARs granted under the Plan terminate, expire
or are canceled without having been exercised (including shares canceled as part
of an exchange of Grants), or if any shares of restricted stock or Phantom Stock
are forfeited, the shares subject to such Grant shall again be available for
subsequent Grants under the Plan.

            (b) If any change is made to the Common Stock (whether by reason of
merger, consolidation, reorganization, recapitalization, stock dividend, stock
split, combination of shares, or exchange of shares or any other change in
capital structure made without receipt of consideration), then unless such event
or change results in the termination of all outstanding Grants under the Plan,
the Committee shall preserve the value of the outstanding Grants by adjusting
the maximum number and class of shares issuable under the Plan to reflect the
effect of such event or change in the Company's capital structure, and by making
appropriate adjustments to the number and class of shares, the exercise price of
each outstanding option and otherwise, except that any fractional shares
resulting from such adjustments shall be eliminated by rounding any portion of a
share equal to .500 or greater up, and any portion of a share equal to less than
 .500 down, in each case to the nearest whole number.

4.    Eligibility for Participation

            Officers and other employees of the Company or an Affiliate, and
non-employee members of the Board shall be eligible to participate in the Plan
(hereinafter referred to individually as an "Eligible Participant" and
collectively as "Eligible Participants"). Only Eligible Participants who are
officers or other employees of the Company or a Parent Corporation or Subsidiary
Corporation shall be eligible to receive Incentive Stock Options. All Eligible
Participants shall be eligible to receive Nonqualified Stock Options, Restricted
Stock Grants, SARs and Phantom Stock. The Committee shall select from among the
Eligible Participants those who will receive Grants (the "Grantees") and shall
determine the number of shares of Common Stock subject to each Grant. The
Committee may, if it so desires, base any such selections or determinations upon
the recommendations of management of the Company. Nothing contained in the Plan
shall be construed to limit in any manner whatsoever the right of the Company to
grant rights or options to acquire Common Stock or awards of Common Stock
otherwise than pursuant to the Plan.

5.    Stock Options

            (a) Number of Shares. The Committee, in its sole discretion, shall
determine the number of shares of Common Stock that will be subject to each
option.

            (b) Type of Option and Option Price.

                  (1) The Committee may grant options qualifying as incentive
      stock options within the meaning of Section 422 of the Code ("Incentive
      Stock Options") and other stock options ("Nonqualified Stock Options"), in
      accordance with the terms and conditions set forth herein, or may grant
      any combination of Incentive Stock Options and Nonqualified Stock Options
      (hereinafter referred to collectively as "Stock Options"). The option
      price per share of an Incentive Stock Option shall be the fair market
      value (as defined herein) of a share of Common Stock on the date of grant.
      The option price per share of a Nonqualified Stock Option shall be
      determined by the Committee, but shall not be less than 90% of the fair
      market value (as defined herein) of a share of Common Stock on the date of
      grant. If the Grantee of an Incentive Stock Option is the owner of Common
      Stock (as determined under section 424(d) of the Code) who possesses more
      than 10% of the total combined voting power of all classes of stock of the
      Company or a Parent Corporation or Subsidiary Corporation, the option
      price per share in the case of an Incentive Stock Option shall not be less
      than 110% of the fair market value of a share of Common Stock on the date
      of grant.

                  (2) For all valuation purposes under the Plan, the fair market
      value of a share of Common Stock shall be the closing price at which the
      Common Stock shall have been sold regular way on the New York Stock
      Exchange on the date as of which such value is being determined or, if no
      sales occurred on such day, then on the next preceding


                                       -3-
<PAGE>   4
      day on which there were such sales, or, if at any time the Common Stock
      shall not be listed on the New York Stock Exchange, the fair market value
      as determined by the Committee on the basis of available prices for such
      Common Stock or in such manner as may be authorized by applicable
      regulations under the Code.

            (c) Exercise Period. The Committee shall determine the option
exercise period of each Stock Option. The exercise period shall not exceed ten
years from the date of grant. However, if the Grantee of an Incentive Stock
Option is the owner of Common Stock (as determined under Section 424(d) of the
Code) who possesses more than 10% of the total combined voting power of all
classes of stock of the Company or a Parent Corporation or Subsidiary
Corporation, the exercise period shall not exceed five years. Notwithstanding
any determinations by the Committee regarding the exercise period of any Stock
Option, all outstanding Stock Options shall become immediately exercisable upon
a Change of Control of the Company (as defined in Section 9 below).

            (d) Vesting of Options and Restrictions on Shares. The vesting
period for Stock Options shall commence on the date of grant and shall end on
the date or dates, determined by the Committee, that shall be specified in the
Grant Letter; provided, however, that unless otherwise specified in the Grant
Letter, each Stock Option shall vest and become exercisable in cumulative
installments to the extent of 25% of the number of shares originally covered
thereby on and after the second, third, fourth and fifth anniversaries of the
grant of the Stock Option, if the Grantee is an employee of the Company or a
Parent Corporation or Subsidiary Corporation (or an Affiliate, in the case of a
Nonqualified Stock Option), or a non-employee member of the Board in the case of
a Nonqualified Stock Option, on such anniversary. The Committee may impose upon
the shares of Common Stock issuable upon the exercise of a Stock Option such
restrictions as it deems appropriate and specifies in the Grant Letter. During
any period in which such restrictions apply, the provisions of Section 6(d)
below shall be applicable to such shares, and the Committee, in such
circumstances as it deems equitable, may determine that all such restrictions
shall lapse. Notwithstanding any other provision of the Plan, all outstanding
Stock Options shall become immediately exercisable upon the earliest to occur of
the following, if at such time the Grantee is an employee of the Company or a
Parent Corporation or Subsidiary Corporation (or an Affiliate, in the case of a
Nonqualified Stock Option), or a non-employee member of the Board in the case of
a Nonqualified Stock Option: (i) the Grantee's normal retirement date, (ii) five
years from the date of the Grant, (iii) the Grantee's death or Disability, or
(iv) the occurrence of a Change of Control of the Company (as defined in Section
9 below). For purposes of this Plan, "Disability" shall mean a physical or
mental impairment of sufficient severity that the Grantee is both eligible for
and in receipt of benefits under the long-term disability program maintained by
the Company.

            (e) Manner of Exercise. A Grantee may exercise a Stock Option by
delivering a duly completed notice of exercise to the Secretary of the Company.
No shares of Common Stock shall be issued on the exercise of a Stock Option
unless paid for in full at the time of purchase. Payment for shares of Common
Stock purchased upon the exercise of a Stock


                                       -4-
<PAGE>   5
Option shall be made in cash or, with the consent of the Committee, in whole or
in part in such shares of Common Stock held for at least six months valued at
the then fair market value thereof. Stock certificates for the shares of Common
Stock so paid will be issued and delivered to the person entitled thereto only
at the Company's office in Philadelphia, PA. No person shall have any rights as
a stockholder with respect to any share of Common Stock covered by a Stock
Option unless and until such person shall have become the holder of record of
such share, and, except as otherwise permitted in Section 3(b) hereof, no
adjustment shall be made for dividends (ordinary or extraordinary, whether in
cash, securities or other property or distributions or other rights) in respect
of such share for which the record date is prior to the date on which such
person shall have become the holder of record thereof.

            (f) Termination of Employment, Disability or Death.

                  (1) If a Grantee ceases to be an Eligible Participant for any
      reason (other than, in the case of an individual, the death of such
      individual) any Stock Option which is otherwise exercisable by the Grantee
      shall terminate unless exercised within three months after the date on
      which the Grantee ceases to be an Eligible Participant (or within such
      other period of time, which may be longer or shorter than three months, as
      may be specified in the Grant Letter), but in any event no later than the
      date of expiration of the option exercise period, except that in the case
      of an individual Grantee who is disabled within the meaning of Section
      22(e)(3) of the Code, such period shall be one year rather than three
      months (except as otherwise provided in the Grant Letter).

                  (2) In the event of the death of an individual Grantee while
      he or she is an Eligible Participant or within not more than three months
      after the date on which the Grantee ceases to be an Eligible Participant
      (or within such other period of time, which may be longer or shorter than
      three months, as may be specified in the Grant Letter), any Stock Option
      which was otherwise exercisable by the Grantee at the date of death may be
      exercised by the Grantee's personal representative at any time prior to
      the expiration of one year from the date of death, but in any event no
      later than the date of expiration of the option exercise period.

            (g) Limits on Incentive Stock Options. Each Grant of an Incentive
Stock Option shall provide that:

                  (1) the Stock Option is not transferable by the Grantee,
      except, in the case of an individual Grantee, by will or the laws of
      descent and distribution;

                  (2) the Stock Option is exercisable only by the Grantee,
      except as otherwise provided herein or in the Grant Letter in the event of
      the death of an individual Grantee; and


                                       -5-
<PAGE>   6
                  (3) the aggregate fair market value of the Common Stock on the
      date of the Grant with respect to which Incentive Stock Options are
      exercisable for the first time by a Grantee during any calendar year under
      the Plan and under any other stock option plan of the Company shall not
      exceed $100,000.

            (h) Exchange Act Limitation. Unless the Grantee could otherwise
transfer Common Stock issued pursuant to the Stock Option without incurring
liability under Section 16(b) of the Exchange Act, at least six months must
elapse from the date of acquisition of the Stock Option until the date of
disposition of the Common Stock issued upon exercise thereof.

            (i) Replacement Options. If a Stock Option granted pursuant to the
Plan may be exercised by a Grantee by means of a stock-for-stock swap method of
exercise as provided in 5(e) above, then the Committee may, in its sole
discretion, authorize the Grantee to automatically receive a replacement Stock
Option pursuant to this part of the Plan. This replacement option shall cover a
number of shares determined by the Committee. The per share exercise price of
the replacement option shall equal the then current fair market value of a share
of Stock, and shall have a term extending to the expiration date of the original
Stock Option. The Committee shall have the right, in its sole discretion and at
any time, to discontinue the automatic grant of replacement options if it
determines the continuance of such grants to no longer be in the best interest
of the Company.

6.    Restricted Stock Grants

            The Committee may issue shares of Common Stock to an Eligible
Participant pursuant to an incentive or long range compensation plan, program or
contract approved by the Committee (a "Restricted Stock Grant"). The following
provisions are applicable to Restricted Stock Grants:

            (a) General Requirements. Shares of Common Stock issued pursuant to
Restricted Stock Grants will be issued for or in consideration for cash or
services rendered having a value, as determined by the Board, at least equal to
the par value thereof. All conditions and restrictions imposed under each
Restricted Stock Grant, and the period of years during which the Restricted
Stock Grant will remain subject to such restrictions, shall be set forth in the
Grant Letter and designated therein as the "Restriction Period." All
restrictions imposed under any Restricted Stock Grant shall lapse on such date
or dates as the Committee may approve until the restrictions have lapsed as to
100% of the shares, except that upon a Change of Control of the Company, all
restrictions on the transfer of the shares which have not been forfeited prior
to such date shall immediately lapse and all such shares shall become fully
vested. In addition, the Committee, in circumstances that it deems equitable,
may determine as to any or all Restricted Stock Grants, that all the
restrictions shall lapse, notwithstanding any Restriction Period.

            (b) Number of Shares. The Committee, in its sole discretion, shall
determine the number of shares of Common Stock that will be granted in each
Restricted Stock Grant.


                                       -6-
<PAGE>   7
            (c) Requirement of Relationship with Company. If the Grantee's
relationship with the Company (as an employee or non-employee member of the
Board, as the case may be) terminates during the period designated in the Grant
Letter as the Restriction Period, the Restricted Stock Grant shall terminate as
to all shares covered by the Grant as to which restrictions on transfer have not
lapsed, and such shares shall be immediately returned to the Company. The
Committee may, in its sole discretion, provide for complete or partial
exceptions to the provisions of this Section 6(c).

            (d) Restrictions on Transfer and Legend on Stock Certificate. During
the Restriction Period, a Grantee may not sell, assign, transfer, pledge or
otherwise dispose of the shares of Common Stock to which such Restriction Period
applies except to a Successor Grantee pursuant to Section 8 below. Each
certificate representing a share of Common Stock issued or transferred under a
Restricted Stock Grant shall contain a legend giving appropriate notice of the
restrictions in the Grant. The Grantee shall be entitled to have the legend
removed from the stock certificate or certificates representing any such shares
as to which all restrictions have lapsed.

            (e) Shareholder Rights. Except as provided in this Section 6, the
Grantee shall have, with respect to shares of Common Stock issued pursuant to a
Restricted Stock Grant, all of the rights of a shareholder, including the right
to vote the shares and the right to receive any cash dividends.

7.    Stock Appreciation Rights

            (a) General Provisions. Stock Appreciation Rights ("SARs") may be
granted in conjunction with all or part of any Stock Option granted under the
Plan. In the case of a Nonqualified Stock Option, such rights may be granted
either at or after the time of grant of such Stock Option. In the case of an
Incentive Stock Option, such rights may be granted only at the time of grant of
such Stock Option. The exercise price of each SAR shall be equal to (i) the
exercise price or option price of the related Stock Option or (ii) the fair
market value of a share of Common Stock as of the date of grant of such Stock
Appreciation Right, but only in such circumstances where the SAR is granted
subsequent to the date of grant of the related Stock Option and an exercise
price established in accordance with clause (i) above would result in the
disallowance of the Company's expense deduction pursuant to Section 162(m) of
the Code.

            (b) Number of SARs. The number of SARs granted to a Grantee which
shall be exercisable during any given period of time shall not exceed the number
of shares of Common Stock which the Grantee may purchase upon the exercise of
the related Stock Option during such period. Upon the exercise of a Stock
Option, the SARs relating to the Common Stock covered by the Stock Option shall
terminate. Upon the exercise of any SARs, the related Stock Option shall
terminate to the extent of an equal number of shares of Common Stock.


                                       -7-
<PAGE>   8
            (c) Settlement Amount. Upon a Grantee's exercise of some or all of
the Grantee's SARs, the Grantee shall receive in settlement of such SARs an
amount equal to the stock appreciation (as defined herein) for the number of
SARs exercised, payable in cash, Common Stock or a combination thereof. The
"stock appreciation" for an SAR is the difference between the option price
specified for the related Stock Option (or the exercise price otherwise
determined under (a), above) and the fair market value of the underlying Common
Stock on the date of exercise of the SAR.

            (d) Settlement Election. Upon the exercise of any SARs, the Grantee
shall have the right to elect the portions of the settlement amount that the
Grantee desires to receive in cash and shares of Common Stock, respectively. For
purposes of calculating the number of shares of Common Stock to be received upon
settlement, shares of Common Stock shall be valued at their fair market value on
the date of exercise of the SARs. Notwithstanding the foregoing, the Committee
shall have the right (i) to disapprove a Grantee's election to receive such
settlement in whole or in part in cash, and to require that shares of Common
Stock be delivered in lieu of cash or (ii) to require that settlement be made in
cash if the Company does not or may not in the future have sufficient shares
authorized for issuance. If shares of Common Stock are to be received upon
exercise of an SAR, cash shall be delivered in lieu of any fractional share.

            (e) Exercise. An SAR is exercisable only during the period when the
Stock Option to which it is related is also exercisable.

8.    Phantom Stock

      (a) General Provisions. The Committee may grant Phantom Stock in such
amounts as it deems appropriate. Phantom Stock shall give the Grantee the right
to receive shares of Common Stock on a conversion date specified by the
Committee. The Committee may establish conditions on the conversion of Phantom
Stock and restrictions on vesting, if any, as it deems appropriate. The period
of years during which a Phantom Stock Grant will be subject to any vesting
restrictions shall be set forth in the Grant Letter and designated as the
"Restriction Period". All vesting restrictions imposed under a Phantom Stock
Grant shall lapse on such date or dates as the Committee may approve, except
that upon a Change of Control of the Company, all restrictions shall immediately
lapse and the Phantom Stock shall become full vested. In addition, the
Committee, in circumstances that it deems equitable, may determine as to any or
all Phantom Stock Grants that the Grants shall not be subject to vesting
restrictions, or that the restrictions shall lapse notwithstanding any
Restriction Period. Each share of Phantom Stock shall be granted at full value
with no exercise price.

      (b) Number of Shares of Phantom Stock; Accounts. The Committee, in its
sole discretion, shall determine the number of shares that will be granted
pursuant to each Phantom Stock Grant. The Company shall credit to a bookkeeping
account established on its records all shares of Phantom Stock credited to a
Grantee.


                                       -8-
<PAGE>   9
      (c) Requirement of Relationship with Company. Except as provided in the
Grant Letter, if the Grantee's relationship with the Company (as an employee or
non-employee member of the Board, as the case may be) terminates during any
period designated in the Grant Letter as the Restriction Period, the Phantom
Stock Grant shall terminate as to all shares covered by the Grant as to which
vesting restrictions have not lapsed, and such shares shall be forfeited. The
Committee may, in its sole discretion, provide for complete or partial
exceptions to the provisions of this Section 8(c).

      (d) Dividend Equivalents. The Company shall credit dividend equivalents on
Phantom Stock as and when dividends are payable on Common Stock. Dividend
equivalents shall be converted to additional shares of Phantom Stock on the
dividend payment date and credited to the Grantee's accounts.

      (e) Conversion. On the date specified in the Grant Letter as the
conversion date for the Grantee's Phantom Stock, the Grantee shall receive in
settlement of such Phantom Stock a number of shares of common Stock equal to the
Phantom Stock then credited to the Grantee's account. Payment shall be made in
whole shares of Common Stock, with fractional shares paid in cash.

      (f) No Rights as a Shareholder. A Grantee shall not have any rights as a
stockholder with respect to any Phantom Stock, and Grantees shall be unsecured
creditors of the Company with respect to Phantom Stock Grants.

9.    Transferability of Options and Grants

      (a) Restrictions on Transferability. Only a Grantee (or, in the case of an
individual Grantee, his or her authorized legal representative) may exercise
rights under a Grant except as otherwise stated herein and in Section 9(b)
below. No individual Grantee may transfer those rights except by will or by the
laws of descent and distribution or, in the case of a Nonqualified Stock Option,
if permitted by the Committee in its sole discretion, pursuant to a qualified
domestic relations order as defined under the Code or Title I of ERISA or the
rules thereunder or pursuant to Section 9(b) below. Upon the death of an
individual Grantee, the personal representative or other person entitled to
succeed to the rights of the Grantee ("Successor Grantee") may exercise such
rights. A Successor Grantee shall furnish proof satisfactory to the Company of
such person's right to receive the Grant under the Grantee's will or under the
applicable laws of descent and distribution.

            (b) Nonqualified Stock Options. Notwithstanding the foregoing, the
      Committee may provide that a Grantee may transfer Nonqualified Stock
      Options to family members, one or more trusts for the benefit of family
      members, or one or more partnerships of which family members are the only
      partners, according to such terms as the Committee may determine; provided
      that the Grantee receives no consideration for the transfer of an


                                       -9-
<PAGE>   10
      Option and the transferred Option shall continue to be subject to the same
      terms and conditions as were applicable to the Option immediately before
      the transfer.

10.   Change of Control of the Company

            As used herein, a "Change of Control" shall be deemed to have taken
place if (i) any Person (except for the employee or his family, the Company or
any employee benefit plan of the Company or of any Affiliate, or any Person or
entity organized, appointed or established by the Company for or pursuant to the
terms of any such employee benefit plan), together with all Affiliates and
Associates of such Person shall become the Beneficial Owner in the aggregate of
20% or more of the shares of the Company then outstanding and entitled to vote
for directors generally, (ii) any Person (except the employee and his family),
together with all Affiliates and Associates of such Person, purchases
substantially all of the assets of the Company, or (iii) during any twenty-four
(24) month period, individuals who at the beginning of such period constituted
the Board cease for any reason to constitute a majority thereof, unless the
election, or the nomination for election by the Company's stockholders, of at
least seventy-five percent (75%) of the directors who were not directors at the
beginning of such period was approved by a vote of at least seventy-five percent
(75%) of the directors in office at the time of such election or nomination who
were directors at the beginning of such period. For purposes of this definition,
"Affiliate" and "Associate" shall have the respective meanings ascribed to such
terms in Rule 12b-2 of the General Rules and Regulations under the Exchange Act;
"Person" shall mean any individual, firm, corporation, partnership or other
entity; and "Beneficial Owner" shall mean:

            (i) that such Person or any of such Person's Affiliates or
      Associates, directly or indirectly, has the right to acquire (whether such
      right is exercisable immediately or only after the passage of time)
      pursuant to any agreement, arrangement or understanding (whether or not in
      writing) or upon the exercise of conversion rights, exchange rights,
      rights, warrants or options, or otherwise; provided, however, that a
      Person shall not be deemed the "Beneficial Owner" of securities tendered
      pursuant to a tender or exchange offer made by such Person or any of such
      Person's Affiliates or Associates until such tendered securities are
      accepted for payment, purchase or exchange;

            (ii) that such Person or any of such Person's Affiliates or
      Associates, directly or indirectly, has the right to vote or dispose of or
      has "beneficial ownership" of (as determined pursuant to Rule 13d-3 of the
      General Rules and Regulations under the Exchange Act), including without
      limitation, pursuant to any agreement, arrangement or understanding
      (whether or not in writing); provided, however, that a Person shall not be
      deemed the "Beneficial Owner" of any security under this subsection (ii)
      as a result of an oral or written agreement, arrangement or understanding
      to vote such security if such agreement, arrangement or understanding (A)
      arises solely from a revocable proxy given in response to a public proxy
      or consent solicitation made pursuant to, and in accordance with, the
      applicable provisions of the General Rules and Regulations under the
      Exchange


                                      -10-
<PAGE>   11
      Act, and (B) is not then reportable by such Person on Schedule 13D under
      the Exchange Act (or any comparable successor report); or

            (iii) where voting securities are beneficially owned, directly or
      indirectly, by any other Person (or any Affiliate or Associate thereof)
      with which such Person (or any of such Person's Affiliates or Associates)
      has any agreement, arrangement or understanding (whether or not in
      writing) for the purpose of acquiring, holding, voting (except pursuant to
      a revocable proxy described in the proviso to subsection (ii) above) or
      disposing of any voting securities of the Company;

      provided, however, that nothing in this definition shall cause a Person
      engaged in business as an underwriter of securities to be the "Beneficial
      Owner" of any securities acquired through such Person's participation in
      good faith in a firm commitment underwriting until expiration of forty
      (40) days after the date of such acquisition.

11.   Dissolution, Liquidation or Winding Up

            If the Company is to be dissolved or liquidated, then, at least ten
days prior to the effective date of such event, the Company shall give each
Grantee with any outstanding Grants written notice of such event. Each such
Grantee shall thereupon have the right to exercise in full any installments of
such Grants not previously exercised (whether or not the right to exercise such
installments has accrued pursuant to such Grants), within ten days after such
written notice is sent by the Company. Any installments of such Grants not so
exercised shall thereafter lapse and be of no further force or effect.

12.   Shareholder Approval

      The Plan is subject to and no Options shall be exercisable hereunder until
after approval of the Plan by holders of a majority of the shares of the stock
of the Company present or represented by a proxy in a separate vote at a duly
held meeting of the stockholders of the Company within twelve months after the
date of the adoption of the Plan by the Board.


13.   Amendment and Termination of the Plan

            (a) Amendment. The Board may amend or terminate the Plan at any
time, subject to the following limitations:

                  (1) the approval by the stockholders of the Company and
      approval by the Compensation Committee shall be required in respect of any
      amendment that (A) materially increases the benefits accruing to Eligible
      Participants under the Plan, (B) increases the aggregate number of shares
      of Common Stock that may be issued or transferred under the Plan (other
      than by operation of Section 3(b) above), (C) increases

<PAGE>   12
      the maximum number of shares of Common Stock for which any Grantee may be
      granted options under the Plan, (D) materially modifies the requirements
      as to eligibility for participation in the Plan, or (E) modifies the
      provisions for determining the fair market value of a share of Common
      Stock; and

                  (2) the Board shall not amend the Plan if such amendment would
      cause the Plan, any Grant or the exercise of any right under the Plan to
      fail to comply with the requirements of Rule 16b-3 under the Exchange Act,
      or if such amendment would cause the Plan or the Grant or exercise of an
      Incentive Stock Option to fail to comply with the requirements of Section
      422 of the Code including, without limitation, a reduction of the option
      price set forth in Section 5(b) above or an extension of the period during
      which an Incentive Stock Option may be exercised as set forth in Section
      5(c) above.

            (b) Termination of Plan. The Plan shall terminate on the tenth
anniversary of its effective date (as set forth in Section 19 below) unless
earlier terminated by the Board or unless extended by the Board with the
approval of the stockholders.

            (c) Termination and Amendment of Outstanding Grants. A termination
or amendment of the Plan that occurs after a Grant is made shall not result in
the termination or amendment of the Grant unless the Grantee consents or unless
the Committee acts under Section 21(b) below. The termination of the Plan shall
not impair the power and authority of the Committee with respect to an
outstanding Grant. Whether or not the Plan has terminated, an outstanding Grant
may be terminated or amended under Section 21(b) below or may be amended by
agreement of the Company and the Grantee which is consistent with the Plan.

14.   Funding of the Plan

            The Plan shall be unfunded. The Company shall not be required to
establish any special or separate fund or to make any other segregation of
assets to assure the payment of any Grants under the Plan. In no event shall
interest be paid or accrued on any Grant, including unpaid installments of
Grants.

15.   Rights of Eligible Participants

            Nothing in the Plan shall entitle any Eligible Participant or other
person to any claim or right to any Grant under the Plan. Neither the Plan nor
any action taken hereunder shall be construed as giving any Eligible Participant
or Grantee any rights to be retained by the Company in any capacity, whether as
an employee, non-employee member of the Board, independent contractor,
consultant or otherwise.

16.   Withholding of Taxes

            The Company shall have the right to deduct from all Grants paid in
cash any federal, state or local taxes required by law to be withheld with
respect to such Grants paid in cash. In the case of Grants paid in Common Stock,
the Company shall have the right to require the Grantee to pay to the Company
the amount of any taxes which the Company is required to withhold in respect of
such Grants or to take whatever action it deems necessary to protect the
interests of the Company in respect of such tax liabilities, including, without
limitation, withholding a portion of the shares of Common Stock otherwise
deliverable pursuant to the Plan. The Company's obligation to issue or transfer
shares of Common Stock upon the exercise of a Stock Option, SAR, or Phantom
Stock Grant or the acceptance of a Restricted Stock Grant shall be conditioned
upon the Grantee's compliance with the requirements of this section to the
satisfaction of the Committee.

17.   Agreements with Grantees

            Each Grant made under the Plan shall be evidenced by a Grant Letter
containing such terms and conditions as the Committee shall approve.

18.   Requirements for Issuance of Shares

            No Common Stock shall be issued or transferred under the Plan unless
and until all applicable legal requirements have been complied with to the
satisfaction of the Committee. The Committee shall have the right to condition
any Stock Option, Restricted Stock Grant, SAR or Phantom Stock Grant on the
Grantee's undertaking in writing to comply with such restrictions on any
subsequent disposition of the shares of Common Stock issued or transferred
thereunder as the Committee shall deem necessary or advisable as a result of any
applicable law, regulation or official interpretation thereof, and certificates
representing such shares may be legended to reflect any such restrictions.

19.   Headings

            The section headings of the Plan are for reference only. In the
event of a conflict between a section heading and the content of a section of
the Plan, the content of the section shall control.


                                      -13-

20.   Effective Dates

            (a) Effective Date of the Plan. The Plan shall be effective as of
January 1, 1995, subject to the approval of the Company's stockholders within 12
months after such effective date.

            (b) Effectiveness of Section 16 Provisions. The provisions of the
Plan that refer to, or are applicable to persons subject to, Section 16 of the
Exchange Act shall be effective, if at all, upon the registration of the Common
Stock under the Exchange Act, and shall remain in effect thereafter for so long
as the Common Stock is registered under the Exchange Act.

21.   Miscellaneous

            (a) Substitute Grants. The Committee may make a Grant to an
employee, a non-employee director, or an independent contractor or consultant of
another corporation, if such person shall become an Eligible Participant by
reason of a corporate merger, consolidation, acquisition of stock or property,
reorganization or liquidation involving the Company or an Affiliate and such
other corporation. Any such Grant shall be made in substitution for a stock
option or restricted stock grant granted by the other corporation ("Substituted
Stock Incentives"), but the terms and conditions of the substitute Grant may
vary from the terms and conditions required by the Plan and from those of the
Substituted Stock Incentives. The Committee shall prescribe the provisions of
the substitute Grants.

            (b) Compliance with Law. The Plan, the exercise of Grants and the
obligations of the Company to issue or transfer shares of Common Stock under
Grants shall be subject to all applicable laws and required approvals by any
governmental or regulatory agencies. With respect to persons subject to Section
16 of the Exchange Act, it is the intent of the Company that the Plan and all
transactions under the Plan shall comply with all applicable conditions of Rule
16b-3 or any successor provisions under the Exchange Act. The Committee may
revoke any Grant if it is contrary to law or modify any Grant to bring it into
compliance with any valid and mandatory government regulations. The Committee
may also adopt rules regarding the withholding of taxes on payments to Grantees.
The Committee may, in its sole discretion, agree to limit its authority under
this section.
