SIGNIFICANT DEVELOPMENT

UNDERWRITERS INDEMNITY HOLDING COMPANY MERGER

     On January 29, 1999, the Company acquired Underwriters Indemnity 
Holdings, Inc., ("UIH") located in Houston, Texas. The Company paid $40.7 
million in cash in exchange for all outstanding shares of UIH subject to 
post-closing contingencies. Included in the transaction were both of UIH's 
operating insurance subsidiaries, Underwriters Indemnity Company of Texas 
("UIC") and Planet Indemnity Company of Colorado ("PIC"). UIC and PIC 
specialize in the marketing and underwriting of surety products for oil, gas, 
mining and other energy-related exposures. Both UIC and PIC are rated "A-" 
(Excellent) by A.M. Best.

(b)  Financial Information about Industry Segments

     Selected information about industry segments is included herein as Item 
8.

(c)  Narrative Description of Business

                               RLI INSURANCE GROUP

     RLI Insurance Group is composed primarily of two main insurance 
companies. RLI Insurance Company, the principal subsidiary, writes multiple 
lines of insurance on an admitted basis in all 50 states, the District of 
Columbia and Puerto Rico. Mt. Hawley Insurance Company, a subsidiary of RLI 
Insurance Company, writes multiple lines of insurance on an admitted basis in 
Kansas and surplus lines insurance in the remaining 49 states, the District 
of Columbia, Puerto Rico, the Virgin Islands and Guam. Other companies in the 
RLI Insurance Group include: Replacement Lens Inc., RLI Insurance Agency, 
Ltd., RLI Insurance Ltd., Underwriters Indemnity Company and Planet Indemnity 
Company.

     Since 1977, when the Company first began underwriting specialty property 
and casualty coverages for commercial risks, highly cyclical market 
conditions and a number of other factors have influenced the Company's growth 
and underwriting profits. The Company, as a "niche" company rather than an 
"all lines" company, seeks to develop expertise and large homogeneous books 
of business in areas generally overlooked by traditional markets.

     In response to the soft market conditions of the early 1980's, which 
were characterized by severe rate competition and excess underwriting 
capacity, the Company limited its writings in specialty property and casualty 
lines and terminated certain lines and sources of production.

                                       2


     Significant rate increases resulted when the insurance market hardened 
in late 1984. The Company responded by expanding its premium volume in 
targeted lines. Since 1987, the industry has experienced generally soft 
market conditions featuring intensified competition for admitted and surplus 
lines insurers, resulting in rate decreases. The Company has continually 
monitored its rates and controlled its costs in an effort to maximize profits 
during this entrenched soft market condition. As a result of catastrophic 
losses, such as Hurricane Andrew and the Northridge Earthquake, property 
rates hardened in California, Florida and the wind belt, but remained soft in 
other areas of the country. In 1994 and 1995, rates hardened and premium 
growth was achieved in the commercial property book of business. Otherwise, 
rates for property and casualty lines have declined over time. To maintain 
profitability, underwriters have tightened selection criteria, broadened 
their focus to other market segments and given up business where rates 
dropped too low.

     The Company initially wrote specialty property and casualty insurance 
through independent underwriting agents. The Company opened its first branch 
office in 1984, and began to shift from independent underwriting agents to 
wholly-owned branch offices which market to wholesale producers. The Company 
also markets certain products to retail producers from its Specialty 
Marketing Division located at the Home Office in Peoria, Illinois. The 
Company produces business under agreements with underwriting general agents. 
Additional underwriting agents are being accepted under the auspices of 
Company product vice presidents. The majority of the specialty property and 
casualty business is marketed through the Specialty Markets and Surety 
divisions and branch offices located in Los Angeles, California; San Diego, 
California; San Francisco, California; Glastonbury, Connecticut; Atlanta, 
Georgia; Alpharetta, Georgia; Honolulu, Hawaii; Chicago, Illinois; Overland 
Park, Kansas; Boston, Massachusetts; St. Paul, Minnesota; New York City, New 
York; Dallas, Texas; Houston, Texas and Seattle, Washington.

     The following table provides for the year ended December 31, 1998 the 
geographic distribution of the Company's risks insured as represented by 
direct premiums earned for all product lines. For the year ended December 31, 
1998, no other state accounted for more than 2% of total direct premiums 
earned for all product lines.

     The Company presently underwrites selected property and casualty 
insurance primarily in the following lines:

                                       3


A.   PROPERTY SEGMENT

     1. COMMERCIAL PROPERTY. The Company's commercial property coverage 
consists primarily of excess and surplus lines and specialty insurance such 
as fire and difference in conditions which includes earthquake, flood and 
collapse coverages. The Company writes coverage for a wide range of 
commercial and industrial classes such as office buildings, apartments, 
condominiums, certain industrial and mercantile structures, and buildings 
under construction. The Company also writes boiler and machinery and ocean 
marine insurance under the same management as commercial property. The 
Alpharetta, Boston, Chicago, Dallas, Houston, Los Angeles, and, San Francisco 
branch offices are responsible for underwriting this coverage. In 1998, 1997, 
and 1996, net earned premiums totaled $42,281,000, $48,799,000, and 
$47,822,000, or 25%, 29%, and 31% respectively, of the Company's consolidated 
revenues.

     2. HOMEOWNERS/RESIDENTIAL PROPERTY. In 1997, the Company assumed a 
highly profitable book of homeowners and dwelling fire business for Hawaii 
homeowners from the Hawaii Property Insurance Association. In the aftermath 
of Hurricane Iniki in 1992, this business was available at reasonable rates 
and terms. Net earned premiums totaled $9,689,000 and $13,229,000 or 6% and 
8% of the Company's consolidated revenues for 1998 and 1997, respectively.

B.   SURETY SEGMENT

     3. SURETY. In 1993, the Company began writing surety business. This 
product line is underwritten from the Home Office in Peoria and through the 
Dallas, Houston and Seattle branch offices. The initial target market of the 
Surety Division was a wide range of commercial surety bonds written primarily 
through the independent agency system. In 1996, the Company expanded their 
product offering to include contract bonds for small size contractors. Net 
earned premiums totaled $18,307,000, $11,491,000, and $4,407,000, or 11%, 8%, 
and 3% of the Company's consolidated revenues for 1998, 1997, and 1996, 
respectively.

     The acquisition of Underwriter's Indemnity Holdings, Inc., and its 
operating insurance subsidiaries provide an ideal situation for our surety 
line to grow in new directions. The facility is a leader in the oil and gas 
field and will begin generating premium income in 1999.

C.   CASUALTY SEGMENT

     4. GENERAL LIABILITY. The Company writes general liability coverages 
through its Los Angeles, Glastonbury, Chicago, Alpharetta, and Dallas branch 
offices. The Company's general liability business consists primarily of 
coverage for third party liability of commercial insureds including 
manufacturers, contractors, apartments and mercantile risks. Net earned 
premiums totaled $23,726,000, $26,332,000, and $34,834,000, or 14%, 16%, and 
22% of the Company's consolidated revenues for the years 1998, 1997, and 
1996, respectively.

     5. COMMERCIAL AND PERSONAL UMBRELLA LIABILITY. The Company's commercial 
umbrella coverage is produced through its Overland Park, St. Paul, 
Alpharetta, Glastonbury, and Dallas branch offices, and through an 
underwriting general agency in San Francisco. The coverage is principally 
written in excess of primary liability insurance provided by other carriers 
and, to a small degree, in excess of primary liability written by the 
Company. The expansion into California and the introduction of internet based 
production of smaller premium light hazard businesses contributed to 
significant premium growth in 1998. The personal umbrella coverage, which is 
produced through the Specialty Markets Division, is written in excess of the 
homeowners and automobile liability coverage provided by other carriers. Net 
earned premiums totaled $29,086,000, $22,566,000, and $21,282,000, or 17%, 
12%, and 14% of the Company's consolidated revenues for the years 1998, 1997, 
and 1996, respectively.

     6. DIRECTORS' AND OFFICERS' LIABILITY/MISCELLANEOUS PROFESSIONAL 
LIABILITY. The Company produces Directors' and Officers' Liability through 
underwriting facilities in San Diego, Los Angeles, and New York City. The 
Company also offers Miscellaneous Professional Liability for a variety of low 
to moderate classes of risks. D&O is a relatively small component of the 
overall P&C market, which has been subject to severe competition. 
Underwriters have relinquished market share rather than accept inadequate 
pricing. Net earned premiums totaled $3,054,000, $4,430,000, and $5,000,000, 
or 2%, 3%, and 3%, of the Company's consolidated revenues for the years 1998, 
1997, and 1996, respectively. 

                                       4


     7. EMPLOYER'S EXCESS INDEMNITY. Since 1993, the Company has written 
Employer's Excess Indemnity coverage for businesses which have opted out of 
the Workers' Compensation plan in the state of Texas. The coverage is similar 
to accident and health, in that it indemnifies the employer for expenses 
resulting from a work related injury or disease, excess of a self-insured 
retention (SIR). The SIR can range from $50,000 to $500,000. The product is 
underwritten out of the Overland Park branch office. A return to excessive 
competition for Texas workers' compensation business has reduced the market 
for this product since 1996. Net earned premiums totaled $1,722,000, 
$5,130,000, and $6,566,000, or 1%, 3%, and 4%, of the Company's consolidated 
revenues for 1998, 1997, and 1996, respectively.

     8. TRANSPORTATION. In 1997, the Company opened a transportation 
insurance facility in Atlanta to offer automobile liability and physical 
damage insurance to local, intermediate and long haul truckers, public 
transportation risks and equipment dealers. Incidental, related insurance 
coverages are also offered, including general liability, commercial umbrella 
and excess liability, and motor truck cargo. The facility is staffed by 
highly experienced transportation underwriters who produce business through 
independent agents and brokers nationwide. Net earned premiums totaled 
$3,806,000 or 2% of the Company's consolidated revenues for 1998.

     9. OTHER. Smaller programs offered by the Company include: excess 
medical, in-home business, personal automobile (Hawaii only), ocean marine 
and occupational accident. Net earned premiums from these lines totaled 
$10,653,000, $9,907,000, and $10,744,000, or 6%, 5%, and 7% of the Company's 
consolidated revenues for the years, 1998, 1997, and 1996, respectively.

COMPETITION

     The Company's specialty property and casualty insurance subsidiaries are 
part of an extremely competitive industry which is cyclical and historically 
characterized by periods of high premium rates and shortages of underwriting 
capacity followed by periods of severe competition and excess underwriting 
capacity. Within the United States alone, approximately 3,500 companies, both 
stock and mutual, actively market property and casualty products. The 
combination of products, service, pricing and other methods of competition 
vary from line to line. The Company's principal methods of meeting this 
competition are innovative products, marketing structure and quality service 
to the agents and policyholders at a fair price. The Company competes 
favorably in part because of its sound financial base and reputation, as well 
as its broad geographic penetration into all 50 states, the District of 
Columbia, Puerto Rico, the Virgin Islands, and Guam. In the property and 
casualty area, the Company has acquired experienced underwriting specialists 
in its branch and Home offices. In 1987, the insurance industry, in general, 
entered into a "soft" or highly competitive period during which insurance 
rates generally decreased. The specialty property and casualty market 
continues to be soft with some rate increases experienced in the property 
lines in California, Florida and the wind belt from 1993 through 1995. Since 
1996, competition reasserted itself and the Company reduced rates somewhat. 
The Company has, however, continued to maintain its underwriting and 
marketing standards by not seeking market share at the expense of earnings. 
New products and new programs are offered where the opportunity exists to 
provide needed insurance coverage with exceptional service on a profitable 
basis.

RATINGS

     During 1992, the A.M. Best rating for RLI Insurance Company, the 
principal subsidiary of the Company, was upgraded to "A" (Excellent). During 
1993, Mt. Hawley Insurance Company's (an indirect subsidiary of the Company) 
A.M. Best rating was upgraded to "A" (Excellent). During 1998, A.M. Best 
reaffirmed "A" ratings for both RLI Insurance Company and Mt. Hawley 
Insurance Company.

     During 1997, the Company for the first time applied for and received a 
claims-paying rating from Standard & Poor's. As a result, rating of "A" 
(Good) was received for the combined insurance operation. In 1998, the "A" 
rating was reaffirmed, with the addition of a "Positive Future Outlook". The 
addition of the positive outlook to the rating indicates that Standard & 
Poor's anticipates that there is a good chance that RLI's rating could 
increase within the next year. 

                                       5


     A.M. Best ratings for the industry range from "A++" (Superior) to "F" 
(In Liquidation) with some companies not being rated. Standard & Poor's 
ratings for the industry range from "AAA" (Superior) to "CC" (Default 
Expected). Publications of both A.M. Best and Standard & Poor's indicate that 
"A" ratings are assigned to those companies that, in their opinion, have 
achieved excellent overall performance when compared to the standards 
established by these firms and have a strong ability to meet their 
obligations to policyholders over a long period of time. In evaluating a 
company's financial and operating performance, both firms reviews the 
company's profitability, leverage and liquidity as well as the company's 
spread of risk, the quality and appropriateness of its reinsurance, the 
quality and diversification of its assets, the adequacy of its policy and 
loss reserves, the adequacy of its surplus, its capital structure and the 
experience and objectives of its management. These ratings are based on 
factors relevant to policyholders, agents, insurance brokers and 
intermediaries and are not directed to the protection of investors.

As of December 31, 1998, the Company had no public debt outstanding, 
therefore, no debt rating existed.

REINSURANCE

     The Company reinsures a significant portion of its property and casualty 
insurance exposure, paying to the reinsurer a portion of the premiums 
received on such policies. Earned premiums ceded to non-affiliated reinsurers 
totaled $135,269,000, $138,198,000, and $140,928,000 in 1998, 1997, and 1996, 
respectively. Insurance is ceded principally to reduce net liability on 
individual risks and to protect against catastrophic losses. Although 
reinsurance does not legally discharge an insurer from its primary liability 
for the full amount of the policies, it does make the assuming reinsurer 
liable to the insurer to the extent of the insurance ceded.

     The Company attempts to purchase reinsurance from a limited number of 
financially strong reinsurers. Retention levels are adjusted each year to 
maintain a balance between the growth in surplus and the cost of reinsurance. 
At December 31, 1998, the Company had prepaid reinsurance premiums and 
reinsurance recoverables on paid and unpaid losses and settlement expenses 
with American Re-Insurance Company (rated A++ "superior" by A.M. Best 
Company) that amounted to 80,365,000. All other reinsurance balances 
recoverable, when considered by individual reinsurer, are less than 10% of 
shareholders' equity.

     The following table sets forth the largest reinsurers in terms of 
amounts recoverable before reinsurance payables from such reinsurers as of 
December 31, 1998. Also shown are the amounts of written premium ceded by the 
Company to such reinsurers during 1998.

     As of December 31, 1998, the Company held $9,448,000 in irrevocable letters
of credit, $7,575,000 under trust agreements and $1,313,508 in cash to
collateralize a portion of the total amount recoverable.

                                       6


     Since 1992, the Company has purchased non-proportional contracts. This 
allows the Company to retain a larger percentage of the premium and a larger 
portion of the initial loss risk. Under non-proportional reinsurance, the 
ceding company retains losses on a risk up to a specified amount and the 
reinsurers assume any losses above that amount. Since 1989, through its 
various reinsurance programs, the Company has generally limited its maximum 
retained exposure on any one risk to $1,000,000. The Company seeks to limit 
its net aggregate exposure to a single catastrophic event to less than 10% of 
shareholders' equity by purchasing various types of reinsurance.

     In 1998, the Company's underwriting was supported by up to $220,000,000 
in traditional reinsurance protection. In 1999, the Company has enhanced this 
protection by adding an additional $30,000,000 in catastrophe reinsurance 
protection at improved terms and conditions. Using computer-assisted 
techniques, the Company quantifies and monitors its exposure to earthquake 
risk, the most significant catastrophe exposure to the Company. Detail is 
captured for each location covered for earthquake risk and the Probable 
Maximum Loss (PML) for each risk is determined. The PML calculation for each 
risk includes all faults to which the risk is exposed. Richter scale 
magnitudes used in the PML calculations are determined and applied separately 
for each fault. The Company uses the greater of the magnitude of an 
earthquake which only occurs every 100 years or 6.5 on the Richter scale in 
its PML calculations. Several widely accepted methods are used to estimate 
the magnitude of the 100 year event for each fault. Underwriting decisions 
are based on the PML as determined by the system, which calculates PML's on 
over 200 faults. Portfolio runs are made regularly to determine the Company's 
overall exposure on each fault from all risks covered. Total exposure after 
facultative reinsurance is managed by the Company to fall within the limits 
covered by the Company's chosen net retention, working layer treaty 
reinsurance and catastrophe reinsurance.

     In 1998, the Company continued its innovative catastrophe reinsurance 
and loss financing program with Centre Reinsurance (Centre Re). The program, 
called Catastrophe Equity Puts (CatEPuts)-SM-, augments the Company's 
traditional reinsurance by integrating its loss financing needs with a 
pre-negotiated sale of securities linked to exchange-traded shares. CatEPuts 
allows the Company to put up to $50.0 million of its convertible preferred 
shares to Centre Re at a pre-negotiated rate in the event of a catastrophic 
loss provided the loss does not reduce GAAP equity to less than $55.0 
million. CatEPuts is intended to be a three-year program and is designed to 
enable the Company to continue operating after a loss of such magnitude that 
its reinsurance capacity is exhausted. If the Company exercises its option to 
put preferred shares to Centre Re, then Centre Re, in turn, has the option to 
reinsure certain business written by the Company on a prospective basis.

FACTORS AFFECTING SPECIALTY PROPERTY AND CASUALTY PROFITABILITY

     The profitability of the specialty property and casualty insurance 
business is generally subject to many factors, including rate competition, 
the severity and frequency of claims, natural disasters, state regulation of 
premium rates, default of reinsurers, interest rates, general business 
conditions, regulatory measures and court decisions that define and expand 
the extent of coverage and the amount of compensation due for injuries or 
losses. One of the distinguishing features of the property and casualty 
insurance business is that its product must be priced before the ultimate 
claims costs can be known. In addition, underwriting profitability has tended 
to fluctuate over cycles of several years' duration. Insurers generally had 
profitable underwriting results in the late 1970's, substantial underwriting 
losses in the early 1980's and somewhat smaller underwriting losses in 1986 
and 1987. During the years 1988 through 1992, underwriting losses increased 
due to increased rate competition and the frequency and severity of 
catastrophic losses, although pre-tax operating income remained profitable 
due to investment income gains. Since 1993, the industry experienced 
improvement in underwriting losses, particularly in years with fewer 
catastrophe losses. The trends experienced during the late 1980s, however, 
have continued, and companies continue to post underwriting losses but remain 
profitable through investment income gains. As well, ongoing rate cuts are of 
concern to financial analysts. For 1998, the industry's statutory combined 
ratio is estimated to be 104.5. The Company believes that certain other 
factors affect its ability to underwrite specialty lines successfully, 
including:

                                       7


     SPECIALIZED UNDERWRITING EXPERTISE. The Company employs experienced 
professionals in its branch offices. Each office restricts its production and 
underwriting of business to certain classes of insurance reflecting the 
particular areas of expertise of its key underwriters. In accepting risks, 
all independent and affiliated underwriters are required to comply with risk 
parameters, retention limits and rates prescribed by the Company's home 
office underwriting group, which reviews submissions and periodically audits 
and monitors underwriting files and reports on losses over $100,000. 
Compensation of senior underwriters is substantially dependent on the 
profitability of the business for which they are responsible. The loss of any 
of these professionals could have an adverse effect on the Company's 
underwriting abilities and earnings in these lines.

     The Company's Underwriting Policy limits extension of binding authority 
to independent agents. The Company's product distribution falls into distinct 
categories, with binding authority following the categorization.

     BROKER BUSINESS. The largest volume of broker generated premium is 
Commercial Property, General Liability, Commercial Umbrella and Commercial 
Automobile. This business is produced through wholesale brokers who are not 
affiliated with the Company. Only a Company underwriter has the authority to 
bind the Company on such risks.

     INDEPENDENT AGENT BUSINESS. The Surety Division offers its business 
through a variety of independent agents. Additionally, the Specialty Markets 
Division writes program business, such as Personal Umbrella and the In-Home 
Business Policy, through independent agents. Homeowners Dwelling Fire and 
Personal Auto are produced through independent agents in Hawaii. Each of 
these programs involves detailed eligibility criteria which are incorporated 
into strict underwriting guidelines. The programs involve prequalification of 
each risk using the "smart" system accessible by the independent agent. The 
independent agent cannot bind the risk unless they receive approval through 
the Company's "smart" system.

     UNDERWRITING AGENTS. The Surety Division has authorized two underwriting 
general agencies to underwrite contract surety business on behalf of RLI, 
primarily in the East and Southeast. An underwriting agency in San Francisco 
is authorized to underwrite commercial umbrella business in select Western 
states. An underwriting agency in New York is authorized to underwrite and 
handle claims for low limit deductible buy-backs on program business, 
primarily in the East. Other underwriting agencies have been designated to 
underwrite programs involving ocean marine insurance, property and liability 
insurance for apartment risks, farm insurance, miscellaneous professional 
insurance and commercial automobile.

     These underwriting general agencies receive some compensation through 
contingent profit commission. Otherwise, producers of business who are not 
Company employees are generally compensated on the basis of direct 
commissions with no provision for any contingent profit commission. There are 
a few volume incentives for producers handling association business, with the 
increased commission involved being tied to the program's underwriting 
profit. This represents less than 5% of the business.

     RETENTION LIMITS. The Company limits its net retention of single and 
aggregate risks through the purchase of reinsurance. See "Business -- 
Specialty Property and Casualty Insurance Segment -- Reinsurance." The amount 
of reinsurance available fluctuates according to market conditions. 
Reinsurance arrangements are subject to annual renewal. Any significant 
reduction in the availability of reinsurance or increase in the cost of 
reinsurance could adversely affect the Company's ability to insure specialty 
property and casualty risks at current levels or to add to the amount thereof.

     CLAIMS ADJUSTMENT ABILITY. The Company has a professional claims 
management team with proven experience in all areas of multi-line claims 
work. This team supervises and administers all claims and directs all outside 
legal and adjustment specialists. Whether a claim is being handled by the 
Company's claim specialist or has been assigned to a local attorney or 
adjuster, detailed attention is given to each claim to minimize loss expenses 
while providing for loss payments in a fair and equitable manner.

                                       8


     EXPENSE CONTROL. Management continues to review all areas of the 
Company's operations to streamline the organization, emphasizing quality and 
customer service, while minimizing expenses. These strategies will help to 
contain the growth of future costs. Maintaining and improving underwriting 
and other key organizational systems continues to be paramount as a means of 
supporting the Company's orderly growth in anticipation of a market rebound, 
as it is the Company's philosophy to retain its talented insurance 
professionals and to build infrastructure in spite of the soft market. Other 
insurance operating expenses as a percent of gross written premiums for the 
years 1998, 1997, and 1996, were 6%, 7%, and 6%, respectively.

     ENVIRONMENTAL EXPOSURES. The Company is subject to environmental claims 
and exposures through its commercial umbrella, general liability, and 
discontinued assumed reinsurance lines of business. Within these lines, the 
Company's environmental exposures include environmental site cleanup, 
asbestos removal, and mass tort liability. The majority of the exposure is in 
the excess layers of the Company's commercial umbrella and assumed 
reinsurance books of business.

     The following table represents inception-to-date paid and unpaid 
environmental exposure data (including incurred but not reported losses) for 
the periods ended 1998, 1997, and 1996:

     Although the Company's environmental exposure is limited as a result of 
entering the liability lines after the industry had already recognized it as 
a problem, Management cannot determine the Company's precise ultimate 
liability with any reasonable degree of certainty. This ultimate liability is 
difficult to assess due to evolving legislation on such issues as joint and 
several liability, retroactive liability, and standards of cleanup. 
Additionally, the Company participates primarily in the excess layers, making 
it even more difficult to assess the ultimate impact.

LOSSES AND SETTLEMENT EXPENSES

     Many years may elapse between the occurrence of an insured loss, the 
reporting of the loss to the insurer and the insurer's payment of that loss. 
To recognize liabilities for unpaid losses, insurers establish reserves, 
which are balance sheet liabilities. The reserves represent estimates of 
future amounts needed to pay claims and related expenses with respect to 
insured events which have occurred.

                                       9


     When a claim is reported, the claims department establishes a "case 
reserve" for the estimated amount of the ultimate payment. The estimate 
reflects the informed judgment of professional claims personnel, based on the 
Company's reserving practices and the experience and knowledge of such 
personnel regarding the nature and value of the specific type of claim. 
Estimates for losses incurred but not yet reported are determined on the 
basis of statistical information, including the Company's past experience. 
The Company does not use discounting (recognition of the time value of money) 
in reporting its estimated reserves for losses and settlement expenses.

     The reserves are closely monitored and reviewed by management, with 
changes reflected as a component of earnings in the current accounting 
period. For lines of business without sufficiently large numbers of policies 
or that have not accumulated sufficient development statistics, industry 
average development patterns are used. To the extent that the industry 
average development experience improves or deteriorates, the Company adjusts 
prior accident years' reserves for the change in development patterns. 
Additionally, there may be future adjustments to reserves should the 
Company's actual experience prove to be better or worse than industry 
averages.

     As part of the reserving process, historical data is reviewed and 
consideration is given to the anticipated impact of various factors such as 
legal developments and economic conditions, including the effects of 
inflation. The reserving process provides implicit recognition of the impact 
of inflation and other factors affecting claims payments by taking into 
account changes in historic payment patterns and perceived probable trends. 
Changes in reserves from the prior years' estimates are calculated based on 
experience as of the end of each succeeding year (loss and settlement expense 
development). The estimate is increased or decreased as more information 
becomes known about the frequency and severity of losses for individual 
years. A redundancy means the original estimate was higher than the current 
estimate; a deficiency means that the current estimate is higher than the 
original estimate.

     Due to the inherent uncertainty in estimating reserves for losses and 
settlement expenses, there can be no assurance that the ultimate liability 
will not exceed amounts reserved, with a resulting adverse effect on the 
Company. Based on the current assumptions used in calculating reserves, 
Management believes the Company's overall reserve levels at December 31, 1998 
are adequate to meet its future obligations.

        Explanation of significant components of reserve development by calendar
        year are as follows:

1996    During 1996, the Company experienced approximately $1,463,000 of
        favorable development on loss reserves. This development resulted from
        approximately $1,519,000 of favorable development in the property lines
        of business. Various property claims closed during the year were settled
        below recorded reserves. The remaining $56,000 of adverse development
        relates to the net effect of changes made to casualty loss reserves.
        This development is a result of reserve strengthening of $3,557,000 made
        in the General Liability and Miscellaneous Professional business on
        accident years 1987 through 1995. This increase was offset by favorable
        development and reserve decreases of $3,501,000 in the Umbrella and
        Excess Employer's Indemnity programs on accident years 1986 and 1993
        through 1995.

1997    During 1997, the Company experienced approximately $520,000 of favorable
        development on loss reserves. The development results from loss reserve
        adjustments in various lines of business. Reserve strengthening was
        necessary on the Property line of business due to development on the
        Lender's Single Interest program. As a result, an increase of $1,465,000
        was made to IBNR reserves. This increase, however, was offset by
        $1,985,000 of favorable development on the Company's other casualty,
        in-home business, and surety bonding programs.

1998    During 1998, the Company experienced $3,402,000 of favorable development
        on loss reserves. This development was the net result from several
        reserve adjustments amongst various programs. Reserve strengthening of
        $2,600,000 to the surety line of business in the third quarter was
        offset by favorable development in primarily the personal umbrella
        product. Favorable development of approximately $3,000,000 on a
        deductible buy-back program resulted in a reclass between loss reserves
        and contingent commissions. This reclass was warranted by favorable loss
        development and had no impact to earnings.

        The table on the following page presents the development under generally
        accepted accounting principles of the Company's balance sheet reserves
        for 1989 through 1998. The top line of the table shows the reserves at
        the balance sheet date for each of the indicated periods. This
        represents the estimated amount of losses and settlement expenses
        arising in all prior years that are unpaid at the balance sheet date,
        including losses that had been incurred but not yet reported to the
        Company. The lower portion of the table shows the re-estimated amount of
        the previously recorded reserves based on experience as of the end of
        each succeeding year. The estimate changes as more information becomes
        known about the frequency and severity of claims for individual periods.

OPERATING RATIO

PREMIUMS TO SURPLUS RATIO

       The following table shows, for the periods indicated, the Company's 
insurance subsidiaries' statutory ratios of net premiums written to 
policyholders' surplus. While there is no statutory requirement applicable to 
the Company which establishes a permissible net premiums written to surplus 
ratio, guidelines established by the National Association of Insurance 
Commissioners provide that this ratio should generally be no greater than 3 
to 1.

combined ratio, which is the sum of (a) the ratio of incurred losses and
settlement expenses to net premiums earned (loss ratio) and (b) the ratio of
policy acquisition costs and other operating expenses to net premiums earned
(expense ratio).

     The Company also calculates the statutory combined ratio, which is not
indicative of GAAP underwriting profits due to accounting for multiple-year
retrospectively-rated reinsurance contracts and policy acquisition costs
differently for statutory accounting purposes compared to GAAP. The statutory
combined ratio is the sum of (a) the ratio of statutory loss and settlement
expenses incurred to statutory net premiums earned (loss ratio) and (b) the
ratio of statutory policy acquisition costs and other underwriting expenses to
statutory net premiums written.

                                   INVESTMENTS

     The investment portfolios of the Company are managed by an Investment
Committee of the Board of Directors. The Company follows an investment policy
that is reviewed quarterly and revised periodically.

     The investment portfolio serves primarily as the funding source for loss
reserves and secondly as a source of income and appreciation. For these reasons,
RLI's primary investment criteria are quality and liquidity, followed by yield
and potential for appreciation. Investments of the highest quality and
marketability are critical for preserving the Company's claims paying ability.
Virtually all of RLI's fixed income investments are U.S. Government or AA-rated
or better taxable and tax- exempt securities. Common stock investments are
limited to securities listed on national exchanges and by the Securities
Valuation Office of the National Association of Insurance Commissioners.

     During 1998, operating cash flows were used to acquire fixed income
instruments composed primarily of intermediate-term municipal and U.S.
Government and Agency securities. Additionally, a smaller portion of funds was
allocated to the equity portfolio and an investment grade convertible debenture
portfolio designed to provide diversification and yield enhancement to the
portfolio.

     RLI's mix of fixed income securities continues to be biased toward U.S.
Government and Agency securities due to their high liquidity and almost
risk-free nature. The mix of tax-exempt and taxable instruments within the
portfolios is decided at the time of purchase on the basis of available
after-tax returns and overall taxability of all invested assets. Almost all
securities reviewed for purchase are either high grade municipal or U.S.
Government or Agency, debt instruments. As part of its investment philosophy,
the Company attempts to avoid exposure to default risk by holding, almost
exclusively, instruments ranked in the top two grades of investment security
quality by Standard & Poor's and Moody's (i.e. AAA and AA). As of December 31,
1998, 96% of the fixed income portfolio was rated AA or better. Interest rate
risk is limited by restricting and managing acceptable call provisions among new
security purchases.

                                       15


     The municipal bond component of the fixed maturity portfolio increased
$28.2 million, to $172.1 million; and comprised 52.3% of the Company's total
fixed maturity portfolio, up 9.2% from year- end 1997. The taxable U.S.
Government and Agency portion of the fixed income portfolio declined by $34.3
million to $143.7 million, or 43.7% of the total versus 53.3% at year end 1997.
Investment grade corporate securities totaled $4.2 million compared to $5.0
million at year- end 1997, while convertible debenture securities totaled $8.9
million, an increase over last year's $6.5 million.

     The Company follows a program of matching assets to anticipated liabilities
to ensure its ability to hold securities until maturity. The Company's long-term
accounts payable and other liabilities are added to the estimate of its unpaid
losses and settlement expenses, broken out by line of business. These
anticipated liabilities are then factored against ultimate payout patterns and
the resulting payout streams are fully funded with the purchase of fixed-income
securities of like maturity. Management believes that both liquidity and
interest rate risk can best be minimized by such asset/liability matching.

     Aggregate maturities for the fixed maturity securities are as follows:

     At December 31, 1998, the Company's equity securities were valued at $296.5
million, an increase of $45.1 million from the $251.4 million held at the end of
1997. During 1998, net common equity investments totaling $8.6 million were
purchased and pretax unrealized appreciation of common equity securities totaled
$36.0 million. Equity securities represented 43.8% of cash and invested assets
at the end of 1998, an increase from the 41.6% at year-end 1997. As of the
year-end, total equity investments held at the operating companies represented
88.2% of the combined statutory surplus of the insurance subsidiaries.

     Combined cash and short-term investments totaling $51.9 million at year-end
1998 represented 7.7% of cash and invested assets versus 3.1% last year. The
Company's short-term investments consist of U.S. Government and Agency backed
money market funds and the highest rated commercial paper.

     Under generally accepted accounting principles, equity and fixed income
securities are carried at fair market value, except that a company that can
demonstrate its ability to hold fixed income securities until their originally
scheduled maturity is permitted to carry such securities at amortized cost. RLI
Corp. has chosen to carry most of its fixed income securities at amortized cost
as it believes it has constructed its fixed income portfolios to match expected
liability payouts and thus has the ability and intention to hold such securities
until their originally scheduled maturity dates. Consequently, fluctuations in
the market value of most bonds are not reflected in the financial statements and
do not affect shareholders' equity.

    The Company's investment results are summarized in the following table:

                                   REGULATION

          STATE REGULATION

     As an insurance holding company, RLI Corp., as well as its insurance
subsidiaries, are subject to regulation by the states in which the insurance
subsidiaries are domiciled or transact business. Holding company registration in
each insurer's state of domicile requires reporting to the state regulatory
authority the financial, operations and management data of the insurers within
the holding company system. All transactions within a holding company system
affecting insurers must be fair, and the insurer's policyholder surplus
following any transaction must be both reasonable in relation to its outstanding
liabilities and adequate for its needs. Notice to regulators is required prior
to the consummation of certain transactions affecting insurance subsidiaries of
the holding company system.

     Other regulations limit the amount of dividends and other distributions the
subsidiaries can pay without prior approval of the insurance department in the
states in which they are physically and/or commercially domiciled, and impose
restrictions on the amount and type of investments they may have. Regulations
designed to ensure financial solvency of insurers and to require fair and
adequate treatment and service for policyholders are enforced by filing,
reporting and examination requirements. Market oversight is conducted by
monitoring trade practices, approving policy forms, licensing of agents and
brokers, and requiring fair and equitable premiums and commission rates.
Financial solvency is monitored by minimum reserve and capital requirements,
periodic reporting procedures (annually, quarterly, or more frequently if
necessary), and periodic examinations.

                                       17


     The quarterly and annual financial reports to the states utilize accounting
principles which are different than the generally accepted accounting principles
that show the business as a going concern. The statutory accounting principles
used by regulators, in keeping with the intent to assure policyholder
protection, are generally based on a liquidation concept. The National
Association of Insurance Commissioners (NAIC) has recently developed a codified
version of these statutory accounting principles, and its deployment in the
states in the near future will foster more consistency among the states for
accounting guidelines and reporting.

     State regulatory authorities have relatively broad discretion with respect
to granting, renewing and revoking brokers' and agents' licenses to transact
business in the state. The manner of operating in particular states may vary
according to the licensing requirements of the particular state, which may,
among other things, require a firm to operate in the state through a
corporation. In a few states, licenses are issued only to individual residents
and locally-owned business entities. In such cases, the Company has arrangements
with residents or business entities licensed to act in the state.

     COMMERCIAL LINES DEREGULATION -- The NAIC and several state legislatures
have taken up the issue of commercial lines deregulation in an attempt to
streamline specific areas of insurance regulation. A growing contingent in the
regulatory community has acknowledged that some regulatory procedures and
practices may be cumbersome and inappropriate for commercial buyers of
insurance. Specifically, the large, sophisticated, multi-state or multi-national
businesses that employ their own teams of risk managers to evaluate, reduce and
finance their loss exposures are less likely to need the form and rate
protections that regulators provide consumers and small to medium business
endeavors. And, while these large businesses may receive some benefit from the
state financial regulation of licensed insurers, it has long been acknowledged
that they do not need the protections addressed by the barriers to the surplus
lines market and other nontraditional markets. Indisputably, deregulation of the
licensed market will have an impact on the surplus lines insurance carriers,
which have been free from form and rate requirements.

     USE OF CREDIT REPORTS IN UNDERWRITING -- Gains in access to electronic
commerce, and the means to gather information more rapidly, have spurred
regulators to take a second look at the use of consumer credit reports in
underwriting and rate making. In some states, regulators charged with protecting
insurance consumers from unfair trade practices, are concerned that some
consumers' risks may be underwritten based solely on their credit standing, and
have sought to strengthen their laws and regulations to address this. This trend
comes on the heels of Congress' re-tooling of the Fair Credit Reporting Act in
1997, which specifically addresses this issue, and permits the use of consumer
credit reports in underwriting. The issue of federal preemption of state action
in this arena has not been judicially addressed.

     LEGISLATION AT FEDERAL LEVEL

     Although the federal government generally does not directly regulate the
insurance business, federal initiatives often have an impact on the business in
a variety of ways. Current and proposed federal measures which may significantly
affect the insurance business include federal preemption of state auto liability
laws, tax reform measures, and Year 2000 legislation. The Company is also
monitoring the following federal proposals:

     NATURAL DISASTER ACT--Recent natural disasters including Hurricane Georges,
continue to fuel concern regarding the best way to provide affordable insurance
coverage for such events. Congress has yet to pass legislation, but proposals to
set up a system for excess federal reinsurance to provide relief to the industry
continue to be discussed. Two Initiatives, "The Natural Disaster Protection and
Insurance Act of 1997" (H.R. 230), and "The Homeowners Insurance Availability
Act of 1997" (H.R. 219), have been the primary tools for discussion and debate.
The Company will continue to monitor the progress of this issue.

                                       18


     FINANCIAL SERVICES MODERNIZATION -- Both judicial decisions and action by
the Office of the Comptroller of the Currency (OCC) have combined to grant
national banks more authority to enter non-banking business, including
insurance. The Barnett Bank decision, which permits the Comptroller of the
Currency to preempt any state law which "significantly interferes" with a bank's
ability to sell insurance products, has spawned the "Financial Services
Competition Act of 1997" (H.R. 10), (also known as "Financial Services
Modernization Legislation"). This Act, designed to shrink the powers of the OCC,
has been the subject of various revisions that would result in both positive and
negative effects on the insurance industry. The bill also contains a provision
that would create a National Association of Registered Agents and Brokers, which
would permit insurance producers to obtain a national license, rather than a
number of state licenses. Obviously, this legislation could have an important
impact on many aspects of the insurance industry; the Company continues to
monitor its progress.

     NATIONAL ASSOCIATION OF INSURANCE COMMISSIONERS

     The National Association of Insurance Commissioners (NAIC) facilitates the
regulation of multi-state companies through uniform reporting requirements,
standardized procedures for financial examinations, and uniform regulatory
procedures embodied in model acts and regulations. Current developments address
the reporting and regulation of the adequacy of capital and surplus.

     The NAIC has developed Property-Casualty Risk-Based Capital (RBC) standards
that relate an insurer's reported statutory surplus to the risks inherent in its
overall operations. The RBC formula uses the statutory annual statement to
calculate the minimum indicated capital level to support asset (investment and
credit) risk and underwriting (loss reserves, premiums written, and unearned
premium) risk. The NAIC model law calls for various levels of regulatory action
based on the magnitude of an indicated RBC capital deficiency, if any. The
Company continues to monitor its subsidiaries' internal capital requirements and
the NAIC's RBC developments. The Company has determined that its subsidiaries'
capital levels are well in excess of the minimum capital requirements for all
RBC action levels. Management believes that its capital levels are sufficient to
support the level of risk inherent in its operations.

                              CORPORATE COMPLIANCE

     The Company has developed a Code of Conduct and Compliance Manual which
provides employees with guidance on complying with a variety of federal and
state laws.

                         AGENCY LICENSES AND TRADEMARKS

     Replacement Lens Inc. or its designated employees, must be licensed to act
as resident or non-resident producers by regulatory authorities in the states in
which it operates.

     RLI Insurance Company obtained service mark registration of the letters
"RLI" in 1998 in the U.S. Patent and Trademark Office. Such registration
protects the mark nationwide from deceptively similar use by the Company's
competitors. The duration of this registration is ten years unless renewed.

                                    CLIENTELE

     No significant part of the Company's or its subsidiaries' business is
dependent upon a single client or upon a very few clients, the loss of any one
of which would have a material adverse effect on the Company.

                                    EMPLOYEES

     The Company employs a total of 405 associates. Of the 405 total associates,
47 are part-time and 358 are full-time.

(d)  Financial Information about Foreign and Domestic Operations and Export
     Sales.

     For purposes of this discussion, foreign operations are not considered
material to the Company's overall operations.

Item 2.  PROPERTIES

     The Company owns a two-story, 80,000 square foot building in Peoria,
Illinois, which serves as the Corporate Headquarters for RLI Corp., RLI
Insurance Company and Mt. Hawley Insurance Company. Two RLI Insurance Company
Branch Offices also lease office space in this building.

     Located on the same 15.0 acre campus is a 12,800 square foot building.
Nearly 9,800 square feet of this building are used as warehouse storage for
records and equipment. The remaining 3,000 square feet are used as office space.

     Additionally, the Company owns two other buildings located near the 
headquarter building. One, a 19,000 square foot building, is leased to Maui 
Jim, Inc. and is used as their headquarters. The other, a 20,000 square foot 
building, was purchased in December of 1996. Currently used for warehousing 
and record storage, this building will provide space for future office 
expansion.

     All other operations of RLI Corp. lease the office space which they need in
various locations throughout the country.

Item 3.  LEGAL PROCEEDINGS

     The Company is involved in certain legal proceedings and disputes
considered by management to be ordinary and incidental to the business or which
have no foundation in fact. Management believes that valid defenses exist as to
all such litigation and disputes, and is of the opinion that these will not have
a material effect on the Company's consolidated financial statements.

Item 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     No matters were submitted by the Company to a vote of security holders
during the fourth quarter of the fiscal year covered by this report.
