NOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS

1.       BASIS OF PRESENTATION

         The interim consolidated financial statements, which have been prepared
         in accordance with accounting principles generally accepted in the
         United States of America (GAAP) are unaudited, but reflect all
         adjustments which, in the opinion of management, are necessary to
         provide a fair statement of the results of Selective Insurance Group,
         Inc. and its consolidated subsidiaries for the interim periods
         presented. References herein to "Selective" are to Selective Insurance
         Group, Inc. and its subsidiaries. All such adjustments are of a normal
         recurring nature. The results of operations for any interim period are
         not necessarily indicative of results for a full year. These interim
         consolidated financial statements cover the first quarters ended March
         31, 2004 (First Quarter 2004) and March 31, 2003 (First Quarter 2003).
         This document should be read in conjunction with the consolidated
         financial statements and notes thereto contained in our Annual Report
         on Form 10-K for the year ended December 31, 2003.

2.       RECLASSIFICATIONS

         Certain amounts in the Company's prior year interim consolidated
         financial statements and related footnotes have been reclassified to
         conform to the 2004 presentation. Such reclassification had no effect
         on the Company's net income or stockholders' equity.

3.       ADOPTION OF ACCOUNTING PRONOUNCEMENTS

         In December 2003, the Financial Accounting Standards Board (FASB)
         issued revised FASB Interpretation No. 46, "Consolidation of Variable
         Interest Entities" (FIN 46R), which is a revised interpretation of
         Accounting Research Bulletin No. 51, "Consolidated Financial
         Statements". FIN 46R is required to be applied starting with fiscal
         years beginning after December 15,2003. FIN 46R requires the
         consolidation of a variable interest entity (VIE) by an enterprise if
         that enterprise either absorbs a majority of the VIE's expected losses
         or receives a majority of the VIE's expected residual returns as a
         result of ownership, contractual or other financial interests in the
         VIE. Prior to FIN 46R, entities were generally consolidated by an
         enterprise that had a controlling financial interest through ownership
         of a majority voting interest in the entity.

         FIN 46R defines a VIE as an entity in which equity investors do not
         have the characteristics of a controlling financial interest nor do
         they have sufficient equity at risk for the entity to finance its
         activities without additional subordinated financial support. The
         Company has no interests in VIEs or potential VIEs commonly referred to
         as special-purpose entities and as such, the adoption of this revised
         interpretation on March 31, 2004 has had no effect on the Company's
         results of operations or financial condition.

4.       ACQUISITION OF WHOLLY-OWNED SUBSIDIARY

         On January 1, 2004, the Company purchased a property and casualty
         insurance company, domiciled in Maine, with approximately $5.0 million
         in surplus that was not currently writing any business, for $5.3
         million. The acquisition has been accounted for using the purchase
         method of accounting as prescribed by FASB Statement of Financial
         Accounting Standards No. 141, "Business Combinations." The acquisition
         included assets of approximately $4.9 million in cash and cash
         equivalents, $0.1 million in bonds and $0.3 million of goodwill, which
         is being accounted for in accordance with FASB Statement of Financial
         Accounting Standards No. 142, "Goodwill and Other Intangible Assets."
         There were no liabilities acquired in connection with this acquisition.

5.       CONCENTRATION OF CREDIT RISK

         Financial instruments that could potentially subject the Company to
         concentration of credit risk include accounts receivable associated
         with our human resource administration outsourcing subsidiary, which
         acts as a co-employer with certain clients. As a co-employer, we
         contractually assume substantial employer rights, responsibilities and
         risks of our clients' employees, who are considered co-employees. These
         accounts receivable, which are included in other trade receivables on
         the consolidated balance sheets, consist of service fees to be paid by
         our clients. Under the accrual method, earned but unpaid wages at the
         end of each period related to the Company's worksite employees are
         recognized as an accrued payroll liability as well as an account
         receivable during the period in which wages are earned by the worksite
         employee. Subsequent to the end of each period, such wages are paid and
         the related co-employer service fees are billed. Accrued co-employer
         payroll and related service fees were $16.2 million as of March 31,
         2004 and $15.5 million as of December 31, 2003. Certain states limit a
         co-employer's liability for earned payroll to minimum wage. This would
         reduce the Company's potential liability for accrued co-employer
         payroll. In the event that a client does not pay their related payroll
         and service fees prior to the applicable payroll date, the Company has
         the right to cancel the co-employer contract or at its option, require
         letters of credit or other collateral. The Company has generally not
         required such collateral. As of March 31, 2004 the maximum exposure to
         any one account for earned payroll is approximately $0.6 million. If
         the financial condition of a client were to deteriorate rapidly,
         resulting in nonpayment, the Company's accounts receivable balances
         could grow and the Company could be required to provide for allowances,
         which would decrease net income in the period that such determination
         was made.

                                       6


         The Insurance Operations and HR outsourcing businesses are also subject
         to geographic concentration. Approximately 37% of our net premiums
         written are for insurance policies written in New Jersey while 40% of
         our HR outsourcing co-employer client payroll is within the state of
         Florida. Other east coast states, including Connecticut, Delaware,
         Georgia, Maryland, New York, North Carolina, Pennsylvania, Rhode
         Island, South Carolina, Virginia and several Midwestern states,
         including Illinois, Indiana, Iowa, Kentucky, Michigan, Minnesota,
         Missouri, Ohio and Wisconsin, account for substantially all of our
         other business. Consequently, changes to economic or regulatory
         conditions in these states could adversely affect the Company.

Ceded losses and loss expenses incurred     (5,057)       (665)


         Assumed business increased primarily due to an increase in mandatory
         pool assumptions. Additionally, the increase in ceded losses and loss
         expenses incurred related to our Flood business and was primarily
         attributable to increases in loss reserves associated with Hurricane
         Isabel, which occurred in third quarter 2003. For additional
         information regarding our reinsurance programs refer to Item 8.

7.       STOCK-BASED COMPENSATION

         The FASB Statement of Financial Accounting Standards No. 123,
         "Accounting for Stock-Based Compensation" (FAS 123) establishes
         financial accounting and reporting standards for stock-based
         compensation plans. As permitted by FAS 123, the Company uses the
         accounting method prescribed by Accounting Principles Board Opinion No.
         25 "Accounting for Stock Issued to Employees" (APB 25) to account for
         its stock-based compensation plans. Companies using APB 25 are required
         to make pro forma footnote disclosures of net income and earnings per
         share as if the fair value method of accounting, as defined in FAS 123,
         had been applied.

         The FASB Statement of Financial Accounting Standards No. 148,
         "Accounting for Stock-Based Compensation - Transition and Disclosure"
         (FAS 148) amends FAS 123 to provide alternative methods of transition
         to FAS 123's fair value method of accounting for stock-based
         compensation. The Company has adopted the pro forma footnote
         disclosure-only provisions of FAS 148. Based on the fair value method
         consistent with the provisions of FAS 148, the Company's net income and
         earnings per share would have been reduced to the following pro forma
         amounts indicated below:



                                                                    UNAUDITED,

8.       SENIOR CONVERTIBLE NOTES

         In 2002, the Company issued $305 million aggregate principal amount of
         1.6155% senior convertible notes (Convertible Notes), due September 24,
         2032, at a discount of 61.988% resulting in an effective yield of
         4.25%. The carrying value of these notes was $115.9 million at March
         31, 2004 and December 31, 2003. The Convertible Notes are convertible
         at the option of the holders, if the conditions for conversion are
         satisfied, into 12.9783 shares of the Company's common stock per $1,000
         principal amount of notes surrendered at a conversion price of $29.29.
         The conditions for conversion are satisfied when the price of the
         Company's common stock has maintained a 20% premium to the conversion
         price of $29.29, or $35.15, for 20 of 30 consecutive trading days
         ending on the last trading day of a calendar quarter.

         As of March 31, 2004, the conditions of conversion were met and as such
         the holders may surrender the Convertible Notes for conversion into
         shares of common stock, or cash at the Company's option, on any
         business day during the second quarter 2004. If all such notes were
         converted, the Company would be required to issue 3.9 million shares of
         common stock. In accordance with the FASB Statements of Financial
         Accounting Standards No. 128 "Earnings per share," the 3.9 million
         shares are included in the diluted earnings per share calculation in
         the quarter when the contingency is met as well as the following
         quarter when the bonds are actually convertible. Therefore, the shares
         are included for the three-month period ended March 31, 2004. During
         any period following the period in which such contingency is not met,
         the convertible notes would cease to be convertible until such time as
         the contingency is again satisfied.

         Holders may also surrender Convertible Notes for conversion during any
         period in which the credit rating assigned to the Convertible Notes is

         interest, if any, or such Convertible Notes to the applicable
         redemption date. The holders of the Convertible Notes may require the
         Company to purchase all or a portion of their Convertible Notes on

         may pay the purchase price in cash or shares of Company common stock or
         in a combination of cash and shares of Company common stock.

9.       SEGMENT INFORMATION

         The Company is primarily engaged in writing property and casualty
         insurance. The Company has classified its business into three segments,
         which is at the same level of disaggregation as that reviewed by senior
         management: Insurance Operations (commercial lines underwriting,
         personal lines underwriting), Investments, and Diversified Insurance
         Services. Insurance Operations are evaluated based on GAAP underwriting
         results, Investments are evaluated based on after-tax investment
         returns, and the Diversified Insurance Services are evaluated based on
         several measures including, but not limited to, results of operations
         in accordance with GAAP. The Company does not aggregate any of its
         operating segments.

         The GAAP underwriting results of the Insurance Operations segment are
         determined taking into account net premiums earned, incurred losses and
         loss expenses, policyholders dividends, policy acquisition costs and
         other underwriting income and expenses. Management of the Investments
         segment is separate from the Insurance Operations segment and,
         therefore, has been classified as a separate segment. The operating
         results of the Investments segment takes into account net investment
         income and net realized gains and losses on investments. The
         Diversified Insurance Services segment is managed independently from
         the other segments and, therefore, has been classified separately. The
         Diversified Insurance Services segment consists of managed care, flood
         operations and human resource administration outsourcing (HR
         outsourcing). The segment results are determined taking into account
         the net revenues generated in each of the businesses, less the costs of
         operations.

         Selective and its subsidiaries provide services to each other in the
         normal course of business. These transactions totaled $6.4 million for
         First Quarter 2004, compared with $6.3 million for First Quarter 2003.
         These transactions were eliminated in all interim consolidated
         financial statements.

         In computing the results of each segment, no adjustment is made for
         interest expense, net general corporate expenses or federal income
         taxes. The Company does not maintain separate investment portfolios for
         the segments and, therefore, does not allocate assets to the segments.

         The following summaries present revenues (net investment income and net
         realized gains in the case of the Investments segment) and pre-tax
         income (loss) for the individual segments:

         required.

         On May 21, 2003, a purported class action was brought by several health
         care providers in the Superior Court of New Jersey, Law Division -
         Camden County, against Consumer Health Network Plus, LLC, Alta
         Services, LLC (Alta) and Selective Insurance Company of America, wholly
         owned subsidiaries of Selective, together with ten other unrelated
         defendants. The plaintiffs purport to represent a class of all New
         Jersey health care providers, except hospitals, who had bills for their
         services paid from personal injury protection benefits under New Jersey
         automobile policies and whose payments were reduced pursuant to a
         preferred provider organization discount schedule. The lawsuit alleges
         that the defendants breached participating provider agreements and
         insurance policies and were unjustly enriched. We are vigorously
         defending this action, and the Company and the other defendants filed a
         Motion to Dismiss. A hearing was held on the Motion and the Court
         ordered the plaintiffs to amend their complaint by March 10, 2004. On
         March 10, 2004 the plaintiffs filed an amended complaint, wherein Alta
         was dropped as a defendant. All defendants expect to file a Motion to
         Dismiss the amended complaint on or about May 14, 2004. Since the suit
         remains in its early stages, management cannot at this time provide a
         meaningful estimate or range of estimates of a potential loss, if any.

securities laws, to publicly update or revise any forward-looking statements,
whether as a result of new information, future events or otherwise. We do not
assume responsibility for the accuracy and completeness of the forward-looking
statements. All of the forward-looking statements in this report are qualified
by reference to the factors discussed under "Risk Factors" beginning on page 18
of our Annual Report on Form 10-K for the year ended December 31, 2003. These
risk factors may not be exhaustive. We operate in a continually changing
business environment, and new risk factors emerge from time to time. We cannot
predict such new risk factors, nor can we assess the impact, if any, of such new
risk factors on our businesses or the extent to which any factor or combination
of factors may cause actual results to differ materially from those expressed or
implied in any forward-looking statements in this report. In light of these
risks, uncertainties and assumptions, the forward-looking events discussed in
this report might not occur.

For these statements, we claim the protection of the safe harbor for
forward-looking statements contained in Section 27A of the Securities Act.

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

The Company is primarily engaged in writing property and casualty insurance. The
Company has classified its businesses into three segments: Insurance Operations
(commercial lines underwriting, personal lines underwriting), Investments, and
Diversified Insurance Services (managed care, flood insurance and human resource
administration outsourcing). Insurance Operations are evaluated based on
underwriting results determined in accordance with GAAP; Investments are
evaluated based on after-tax investment returns; and the Diversified Insurance
Services are evaluated based on several measures including, but not limited to,
results of operations determined in accordance with GAAP. For an additional
description of accounting policies, refer to Item 8. "Financial Statements and
Supplementary Data," Note 2 to our consolidated financial statements on pages 50
through 55 of the 10-K section of our Annual Report to Shareholders for the
year-ended December 31, 2003 and the discussion beginning on page 19 of this
report on Form 10-Q. See Note 9 to the March 31, 2004 unaudited interim
consolidated financial statements on pages 9 and 10 of this report on Form 10-Q
for revenues and related income before federal income tax for each individual
segment discussed below.

The following discussion relates to our results of operations, financial
condition, liquidity and capital resources, off-balance sheet arrangements,
contractual obligations and contingent liabilities and commitments and critical
accounting policies for the interim periods indicated. This discussion is
prepared in accordance with accounting principles generally accepted in the
United States of America (GAAP) unless otherwise noted.

RESULTS OF OPERATIONS

The following discussion is a comparison of the first quarter ended March 31,
2004 (First Quarter 2004) to the first quarter ended March 31, 2003 (First
Quarter 2003).

Our net income was $27.5 million, or $0.88 per diluted share, for First Quarter
2004, compared with $8.0 million, or $0.29 per diluted share, for First Quarter
2003. Included in net income are net realized capital gains, after-tax, of $3.5
million for First Quarter 2004, compared with $2.6 million for First Quarter
2003.

Net premiums written increased by approximately $51.9 million, or 16%, to $375.3
million in First Quarter 2004 compared with First Quarter 2003. The main factors
contributing to this overall improvement were: (i) $75.5 million in net new
business written in First Quarter 2004, an increase of 16% compared with $65.1
million in First Quarter 2003, 90% of which was generated in our commercial
lines in First Quarter 2004 compared with 87% in First Quarter 2003; (ii)
commercial lines year-on-year retention improvement of 3 points to 83% in First
Quarter 2004 compared with 80% for First Quarter 2003; and (iii) commercial
lines renewal premium price increases that averaged 10% in First Quarter 2004
compared with 15% in First Quarter 2003. We anticipate these increases will
decelerate in 2004. For further information, see discussion of "Commercial Lines
Results" on the next page.

The loss and loss expense ratio decreased 7.9 points to 66.7% for First Quarter
2004 when compared with First Quarter 2003. The improvements were primarily due
to increased premium rates and underwriting improvements mainly in our
commercial lines business, which comprises 83% of net premium written for the
fiscal year ending March 31, 2004. Additionally, four-plus years of double-digit

                                       12


commercial lines renewal premium price increases, which on a compounded basis
totaled 92%, and reduced weather catastrophe losses of $4.7 million, or 1.5
points for the First Quarter 2004, compared with $11.9 million, or 4.4 points,
in First Quarter 2003 contributed to a more favorable loss and loss expense
ratio.

The underwriting expense ratio decreased 0.6 points to 30.9% for First Quarter
2004 compared with the same period in 2003. Overall productivity, as measured by
fiscal year net premiums written per insurance operations employee, was
approximately $739,000 for the fiscal year ended March 31, 2004, up from
$608,000 for the same period in 2003. Contributing to the overall productivity
are our strategic initiatives which are designed to either reduce costs and/or
increase business, which include: i) streamlined processing for small commercial
lines accounts (One & Done) and ii) a web-based commercial lines automated
system. These technology enhancements enable agents to initiate and self-service
their Selective business. During the quarter, agents managed over 13% of
endorsements through our automated commercial lines system, and our automated
underwriting templates automatically processed 28% of renewals. We are on pace
to process, through our automated systems, 40% of certain commercial lines
transactions by year-end.

The combined ratio decreased 8.8 points to 97.9 in First Quarter 2004 compared
with 106.7 in First Quarter 2003. The reasons for the decrease in the combined
ratio are primarily attributable to the previously discussed decreases in the
loss and loss expense ratio as well as the underwriting expense ratio.

Commercial Lines Underwriting accounted for approximately 83% of our net
premiums written for the fiscal year ended March 31, 2004 compared with 81% for
the same period last year. Net premiums written increased $50.2 million, or 19%,
to $320.0 million for First Quarter 2004 compared with First Quarter 2003. The
main factors contributing to this overall improvement were: (i) $68.3 million in
net new business written for First Quarter 2004, a 20% increase when compared
with $56.8 million in net new business written for First Quarter 2003; (ii)
year-on-year retention improvement of 3 points to 83% in First Quarter 2004
compared with 80% for First Quarter 2003; and (iii) renewal premium price
increases that averaged 10% in First Quarter 2004 compared with 15% in First
Quarter 2003.

Even though our long-term strategy incorporates higher pricing throughout our
Commercial Lines operation, we expect pricing increases to continue to moderate
in 2004. We anticipate earned premiums, excluding exposure, to increase 7.5% and
continue to outpace loss trends, which are expected to rise by 4% for the full
year 2004. Our projected loss trend is based upon an expected 2% increase in
CPI, including medical costs increases of 5 to 7%.

For First Quarter 2004, the Commercial Lines Underwriting loss and loss expense
ratio decreased 10.2 points when compared with the same period in 2003. Weather
related catastrophes accounted for 1.6 points of the loss and loss expense ratio
for First Quarter 2004 compared with 4.8 points in First Quarter 2003. In
addition to more favorable weather experience compared to First Quarter 2003,
our solid performance in these lines reflects our long-term improvement strategy
that incorporates higher pricing, demonstrated by our compounded 92% renewal
premium price increases achieved over the past four years, continued
underwriting enhancements, and heightened loss control efforts, all of which led
to improved financial results.

                                       13


For First Quarter 2004, the Commercial Lines Underwriting combined ratio
decreased 10.4 points to 96.2% from 106.6% for the same period in 2003. The
favorable First Quarter 2004 results were driven by improvements in the
previously discussed loss and loss ratio, which resulted in improvements in
almost every segment of our core commercial lines operation, except for our bond
operation. The bond unit had a $2.0 million reduction of a salvage and
subrogation recoverable related to prior accident years, which increased the
overall Commercial Lines combined ratio by one point.

               COMMERCIAL AUTOMOBILE BUSINESS

Our commercial automobile line of business accounted for 28% of Commercial Lines
Underwriting net premiums earned in First Quarter 2004 and First Quarter 2003.
This line registered a strong quarter, with a statutory loss and loss expense
ratio of 56.4%, down almost six points compared with 62.1% in First Quarter
2003. This line has been favorably impacted by price increases, stricter
underwriting standards, including a changed vehicle mix which reduced the
percentage of extra-heavy vehicles covered, and the removal of certain classes
of business that we determined to be unprofitable.

               WORKERS COMPENSATION BUSINESS

Our workers' compensation line of business, which accounted for 24% of
commercial lines underwriting net premiums earned in First Quarter 2004 and
First Quarter 2003, showed marked improvement when compared with the same period
last year, posting a statutory loss and loss expense ratio of 80.8% for First
Quarter 2004, compared with 84.2% for First Quarter 2003. This improvement is
further supported by the fact that the Company continues to maintain an
underwriting position for the workers' compensation business that focuses on low
to medium hazard business with less than 5% of the business being unsupported by
another commercial line. In addition to focusing on low to medium hazard
business, our underwriting measures also include requiring job site inspections
and increasing the number of highly trained loss control representatives we
employ. This, together with the fact that since 2000 we have increased pricing
by 40% through a combination of rate increases, credit reductions, restricting
dividend plans and shifting business to higher-priced tiers, are the main
reasons why this book of business performed better than First Quarter 2003. Our
underwriting and pricing actions are ongoing, including a targeted 6% price
increase in 2004. A 6.2% price increase in New Jersey, which represents 24% of
our workers' compensation premium written, was effective January 1st.

               GENERAL LIABILITY BUSINESS

Our general liability line of business, which accounted for 28% of Commercial
Lines Underwriting net premiums earned in First Quarter 2004 and in First
Quarter 2003, recorded a statutory loss and loss expense ratio of 58.8%, down
almost five points compared with 63.6% in First Quarter 2003. Our solid
performance in this line reflects our long-term improvement strategy that
incorporates higher pricing, continued underwriting enhancements, and heightened
loss control efforts.

               COMMERCIAL PROPERTY BUSINESS

Our commercial property business, which accounted for 10% of Commercial Lines
Underwriting net premiums earned for First Quarter 2004 and First Quarter 2003,
posted a statutory loss and loss expense ratio of 63.0%, including 9.8 points of
catastrophe losses, compared with a statutory loss and loss expense ratio of
123.3%, including 43.8 points of catastrophe losses, in First Quarter 2003. We
continue to implement ongoing pricing and underwriting actions to improve
results in this line of business, which include: better insurance to value
estimates across our book of business; a shift to risks of better construction
quality and newer buildings; and an overall focus on low-to-medium hazard
property exposures.

Personal Lines Underwriting accounted for approximately 17% of our net premiums
written for the fiscal year ended March 31, 2004 compared with 19% for the same
period last year. Net premiums written increased $1.6 million, or 3%, to $55.3
million for First Quarter 2004 when compared with the same period in 2003. The
combined ratio was 105.5% for First Quarter 2004, including 1.0 point of
catastrophe losses, down 1.9 points from the same period in 2003, which had a
combined ratio of 107.4%, including 3.1 points of catastrophe losses. More than
offsetting the lower catastrophe losses compared with First Quarter 2003, were
unusual fire losses in First Quarter 2004. These unusual fire losses have driven
up severity, increasing the loss and loss expense ratio to 79.0% in First
Quarter 2004 compared with 75.7% in First Quarter 2003. Additionally, the
expense ratio declined as a result of reduced expenses and a change in deferred
acquisition cost amortization estimates, which were revised to better match
acquisition expenses and earned premiums.

               PERSONAL AUTOMOBILE BUSINESS

Our personal automobile results constituted 83% of personal lines underwriting
net premium earned in First Quarter 2004 and First Quarter 2003. The personal
automobile line produced a statutory loss and loss expense ratio of 71.5% for
First Quarter 2004, compared with 74.9% for First Quarter 2003. The improved
results were attributable to our business in New Jersey, which accounted for 73%
of our overall personal automobile net premiums earned for First Quarter 2004
and First Quarter 2003. Continued progress in New Jersey is the result of
significant actions taken over the last four years, including aggressive pricing
initiatives; a redesign of our rating tiers; reduced agency commissions; and an
improving political and regulatory climate. While we are pleased with this
improvement, our efforts to achieve stability in this often volatile book of
business continues. Building on a 5% rate increase effective in March 2004, our
action plans include further tier revisions expected to lower rates for our best
customers and improve our competitive position in this changing marketplace.

In New York, we no longer focus on writing personal lines due to regulatory
challenges and the high cost of the involuntary automobile insurance market that
make it extremely difficult to do business. Our net premiums written in New York
decreased 32%, to $1.2 million in First Quarter 2004 compared with $1.8 million
in First Quarter 2003. New York now accounts for only 3% of our total personal
lines net premiums written. Our statutory loss and loss expense ratio in New
York was 127.5% in First Quarter 2004 compared with 84.5% in First Quarter 2003.

               HOMEOWNERS BUSINESS

Our homeowners line of business, which accounted for 15% of personal lines net
premiums earned for First Quarter 2004, compared with 14% for First Quarter
2003, had a statutory loss and loss expense ratio of 93.1% for First Quarter
2004, of which 7.1 points are attributable to weather-related catastrophes,
compared with 85.8% for First Quarter 2003, which had 20.2 points from
weather-related catastrophes. This line was further impacted by several
non-catastrophe large fire losses, which added 38.1 points to the statutory loss
and loss expense ratio in First Quarter 2004. While the unusual fire losses have
driven up severity, our underlying homeowner's book continued to improve. During
First Quarter 2004, frequency continued its downward trend; premiums continue to
rise; and we implemented ongoing enhancements to the improvement plan initiated
three years ago, including: (i) double-digit rate increases in six states; (ii)
expanding the use of credit history to apply discounts and surcharges for new
and renewal business; (iii) continuing the rollout of higher wind and hail
deductibles in coastal and selected inland territories; and (iv) expanding the
account credit, where appropriate, to encourage agents to write entire accounts.

INVESTMENTS

Although lower interest rates continue to put pressure on investment returns, we
generated an 8% increase in investment income to $29.5 million for First Quarter
2004, up from $27.3 million for First Quarter 2003. The increase reflects an
increased asset base as our investment portfolio reached $2.5 billion at March
31, 2004, compared with $2.2 billion at March 31, 2003. This increase is due to
strong operating cash flows of $281.9 million last year and $55.2 million in
First Quarter 2004 compared with $41.0 million in First Quarter 2003. Also
contributing to the increase were our limited partnership investments. These
investments, which are subject to market fluctuations, added $2.1 million to
investment income for First Quarter 2004, compared with $0.4 million for First
Quarter 2003. Our before-tax portfolio yield was 4.8% in First Quarter 2004
compared with 5.1% in First Quarter 2003.

We continue to maintain a conservative, diversified investment portfolio, with
debt security holdings representing 84% of invested assets. 63% of our debt
securities portfolio is rated "AAA" while the portfolio has an average rating of
"AA," Standard & Poor's second highest credit quality rating. High credit
quality continues to be a cornerstone of our investment strategy, as evidenced
by the fact that 99% of the debt securities are investment grade.

We emphasize liquidity requirements in response to an unpredictable underwriting
environment and the need to minimize the exposure to catastrophic events. To
provide liquidity while maintaining consistent performance, debt securities are
"laddered" so that some issues are always approaching maturity, thereby
providing a source of predictable cash flow. To reduce sensitivity to interest
rate fluctuations, we invest our debt securities portfolio primarily in
intermediate-term securities. The average maturity of the portfolio at March 31,
2004 was 5.3 years compared with 5.5 years at December 31, 2003.

We continue to follow an investment philosophy that has historically proven
successful. The strategy is to purchase debt securities in sectors that we
believe represent the most attractive relative value and maintain a moderate
equity exposure. Managing investment risk by adhering to these strategies is
intended to protect the interests of our stockholders as well as those of our
policyholders and, at the same time, enhance our financial strength and
underwriting capacity.

At March 31, 2004 our investment portfolio included non-investment grade
securities with an amortized cost of $20.5 million, (1% of the portfolio), and a
fair value of $22.4 million. At December 31, 2003, non-investment grade
securities in our investment portfolio represented less than 1% of the
portfolio, with an amortized cost of $25.2 million and a fair value of $27.2
million. The unrealized loss on these securities represented 16% of our total
unrealized loss at March 31, 2004, and 5% at December 31, 2003. The fair value
of these securities was determined by independent pricing services or bid prices
provided by various broker dealers. The Company did not have a material
investment in non-traded securities at March 31, 2004, or at December 31, 2003.

The Company regularly reviews the diversification of the investment portfolio
compared with an investment grade corporate index. At March 31, 2004, 17% of the
market value of our corporate bond and preferred stock portfolios were
represented by investments in banks, only two of which were in an unrealized
loss position, compared with 11% in the benchmark corporate index. The average
Moody's rating for the banking portfolio is "A1" with the lowest rated
securities at "Baa1" and the average Standard and Poor's rating is "A", with the
lowest rated security at "BBB".

The Company regularly reviews its investment portfolio for declines in value,
focusing attention on securities whose market value is less than 85% of their
cost/amortized cost at the time of review. If we believe a decline in the value
of a particular investment is temporary, we record the decline as an unrealized
loss in accumulated other comprehensive income. If we believe the decline is
"other than temporary," we write down the carrying value of the investment and
record a realized loss in our consolidated statements of income. Our assessment
of a decline in value includes our current judgment as to the financial position
and future prospects of the entity that issued the investment security. Broad
changes in the overall market or interest rate environment generally will not
lead to a write-down. If our judgment about an individual security changes in
the future we may ultimately record a realized loss after having originally
concluded that the decline in value was temporary, which could have a material
impact on our net income and financial position of future periods. Factors
considered, but not limited to, in evaluating potential impairment of debt
securities include the following:

         -     Whether the decline appears to be issuer or industry specific;

         -     The degree to which an issuer is current or in arrears in making
               principal and interest payments on the debt securities in
               question;

         -     The issuer's current financial condition and its ability to make
               future scheduled principal and interest payments on a timely
               basis;

         -     Buy/hold/sell recommendations published by outside investment
               advisors and analysts; and

         -     Relevant rating history, analysis and guidance provided by rating
               agencies and analysts.

Factors considered, but not limited to, in evaluating potential impairment of
equity securities include the following:

         -     Whether the decline appears to be issuer or industry specific;

         -     The relationship of market prices per share to book value per
               share at the date of acquisition and date of evaluation;

REALIZED GAINS AND LOSSES

Realized gains and losses are determined on the basis of the cost of specific
investments sold or written-down, and are credited or charged to income.
Realized losses include impairment charges from investment write-downs for other
than temporary declines, if any, in the period such determination is made. There
were no impairment charges recorded during First Quarter 2004 or First Quarter
2003. The Company realized gains and losses from the sale of available-for-sale
debt and equity securities during First Quarter 2004 and First Quarter 2003.

The following table presents the period of time that securities, sold at a loss
during these periods, were continuously in an unrealized loss position prior to
sale:

These securities were sold despite the fact that they were in a loss position.
The decision to sell these securities was due to: (i) heightened credit risk of
the individual security sold, (ii) the need to reduce our exposure to certain
issuers, industries or sectors in light of changing economic conditions, or
(iii) tax planning strategies.

The Diversified Insurance Services generated $24.2 million of net revenue and
$1.5 million of net income in First Quarter 2004 compared with $21.3 million of
revenue and $1.3 million of net income in the First Quarter 2003. The segment
generated a return on net revenue of 6.1% in the First Quarter 2004 and the
First Quarter 2003. Operating cash flow from the segment was $5.3 million in
First Quarter 2004 compared with $0.7 million in First Quarter 2003.

HUMAN RESOURCE ADMINISTRATION OUTSOURCING (HR OUTSOURCING)

HR outsourcing net revenues increased 22% to $13.0 million for First Quarter
2004 compared with $10.7 million last year. Pre-tax income was $0.1 million for
First Quarter 2004, which was flat compared with First Quarter 2003. With
expense reduction and re-underwriting initiatives firmly in place, we are
focusing our efforts on growing this business. At the end of First Quarter 2004,
our worksite lives are up 10% to 20,540 compared with 18,735 at March 31, 2003.

MANAGED CARE

Net revenues decreased 14% to $4.9 million for First Quarter 2004 compared with
$5.6 million for First Quarter 2003. This reduction reflected the loss of
business that occurred primarily as a result of industry consolidation, the
eliminations of unprofitable accounts, and the loss of one large client to a
competitor. Decreased net revenues resulted in a corresponding decrease in
pre-tax profit to $0.5 million for First Quarter 2004 compared with $1.0 million
for First Quarter 2003.

FLOOD INSURANCE

Premium growth of 19% for First Quarter 2004 compared with First Quarter 2003
has been driven by enhanced marketing efforts with the personal lines
underwriting operation that have resulted in new business of $3.9 million for
First Quarter 2004 and First Quarter 2003. This growth increases our total
premium served to $68.3 million compared with $55.3 million a year ago and has
resulted in increased servicing fees of $5.7 million for First Quarter 2004
compared with $4.6 million for First Quarter 2003. The growth has also driven
increases in pre-tax profit to $1.4 million for First Quarter 2004 compared with
$0.8 million for First Quarter 2003.

FEDERAL INCOME TAXES

Total federal income tax expense increased $8.7 million for First Quarter 2004
to $10.0 million, compared with the same period last year. These amounts reflect
an effective tax rate of 27% for the First Quarter 2004, compared with 14% for
the same period last year. The increase was attributable to improved
underwriting results, increased capital gains on investment sales, and higher
levels of taxable investment income. Our effective tax rate differs from the
federal corporate tax rate of 35% primarily as a result of tax-exempt investment
income and the dividends received deduction.

ADOPTION OF ACCOUNTING PRONOUNCEMENT

In December 2003, the Financial Accounting Standards Board (FASB) issued revised
FASB Interpretation No. 46, "Consolidation of Variable Interest Entities" (FIN
46R), which is a revised interpretation of Accounting Research Bulletin No. 51,
"Consolidated Financial Statements". FIN 46R is required to be applied starting
with fiscal years beginning after December 15, 2003. FIN 46R requires the
consolidation of a variable interest entity (VIE) by an enterprise if that
enterprise either absorbs a majority of the VIE's expected losses or receives a
majority of the VIE's expected residual returns as a result of ownership,
contractual or other financial interests in the VIE. Prior to FIN 46R, entities
were generally consolidated by an enterprise that had a controlling financial
interest through ownership of a majority voting interest in the entity.

                                       19


FIN 46R defines a VIE as an entity in which equity investors do not have the
characteristics of a controlling financial interest nor do they have sufficient
equity at risk for the entity to finance its activities without additional
subordinated financial support. The Company has no interests in VIEs or
potential VIEs commonly referred to as special-purpose entities and as such, the
adoption of this revised interpretation on March 31, 2004 has had no effect on
the Company's results of operations or financial condition.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES

Selective Insurance Group, Inc. (Parent) is an insurance holding company whose
principal assets are investments in its subsidiaries. The Parent's primary means
of meeting its liquidity requirements is through dividends from these
subsidiaries. The payment of dividends from the insurance subsidiaries is
governed by state regulatory requirements, and these dividends are generally
payable only from earned surplus as reported in our statutory Annual Statements
as of the preceding December 31. Based upon the 2003 unaudited statutory
financial statements, the Insurance Subsidiaries are permitted to pay the Parent
in 2004 ordinary dividends in the aggregate amount of approximately $64.0
million. There can be no assurance that the Insurance Subsidiaries will be able
to pay dividends to the Parent in the future in an amount sufficient to enable
the Parent to meet its liquidity requirements. For additional information
regarding regulatory limitations on the payment of dividends by the insurance
subsidiaries to the Parent and amounts available for the payment of such
dividends, refer to Item 8. "Financial Statements and Supplementary Data", Note
8 to the consolidated financial statements on page 62 of the 10-K section of our
Annual Report to Shareholders for the year ended December 31, 2003.

The payment of dividends from Diversified Insurance Services subsidiaries are
restricted only by the available operating cash flows of those subsidiaries.
Growth in the Diversified Insurance Services segment has augmented consolidated
cash flows from operations by generating $5.3 million in 2004, compared with
$0.7 million in 2003. The operating cash flows from the Diversified Insurance
Services segment, which are only restricted by ongoing operational needs of
those businesses, resulted in dividends to the Parent of $5.7 million in 2004
and $5.9 million in 2003.

The Parent also generates cash from the sale of its common stock under various
stock plans, the dividend reinvestment program, and from investment income, all
of which approximated $3.9 million and reduced the Parent's cash requirements
for the quarter from $8.4 million to $4.5 million.

The Parent's cash requirements include principal and interest payments on the
senior convertible notes, various notes payable and convertible subordinated
debentures, dividends to stockholders and general operating expenses. The
Company has contractual principal obligations pursuant to various notes payable
of $24.0 million in 2004. As part of our senior convertible note issuance in
2002, the Company established an irrevocable trust in the approximate amount of
$72.0 million. As of March 2004, approximately $47.4 million remains in the
trust to provide funds for the notes with maturities in the next two years. The
2002 convertible note issuance has a contingent conversion feature that permits
the holders of the notes to convert the notes when the price of the Company's
common stock has maintained a 20% premium to the conversion price of $29.29, or
$35.15, for 20 of 30 consecutive trading days ending on the last trading day of
the previous calendar quarter. As this contingency was met as of March 31, 2004,
on any business day in the second quarter of 2004, the holders may surrender
notes for conversion into shares of common stock, or cash at the Company's
option. As a result of this condition being met, 3.9 million shares of common
stock were added to our diluted earnings per share calculation in both First
Quarter 2004 when the contingency was met, and in the following quarter when the
bonds are actually convertible. See Note 8 to the unaudited interim consolidated
financial statements for more information on our senior convertible notes.

Dividends to stockholders are declared and paid at the discretion of the Board
of Directors based upon the Company's operating results, financial condition,
capital requirements, contractual restrictions and other relevant factors. The
Parent has paid regular quarterly cash dividends to its stockholders for 75
consecutive years, including a $0.02 increase per share in the fourth quarter of
2003, to $0.17 per share, and currently plans to continue to pay quarterly cash
dividends. For information regarding restrictions on the Parent's ability to pay
dividends to its stockholders, refer to Item 8. "Financial Statements and
Supplementary Data", Note 7(b) to the consolidated financial statements on page
61 of the 10-K section of our Annual Report to Shareholders for the year ended
December 31, 2003.

On November 4, 2003, the Board of Directors authorized a 2.5 million share stock
repurchase program scheduled to expire on November 30, 2005. This program
replaces the previous stock repurchase program that expired on May 31, 2003. No
shares have been repurchased under the current program.

In addition to the cash requirements of the Parent, our operating obligations
and cash outflows include: claim settlements; commissions; labor costs; premium
taxes; general and administrative expenses; investment purchases; and capital
expenditures. The Insurance Subsidiaries also have additional investment
commitments for their limited partnership investments of up to $38.3 million;
however, there is no certainty that any additional investment will be required.
The Insurance Subsidiaries satisfy their obligations and cash outflows through
premium collections, interest and dividend income and maturities of investments.

Cash provided by operating activities amounted to $55.2 million in First Quarter
2004 and $41.0 million in First Quarter 2003. This increase in 2004 is a result
of: i) a 16% increase in net premiums written and improved underwriting
profitability, driven by rate increases in renewal premiums; and ii) increased
investment income from a larger investment portfolio.

                                       20


Since cash inflow from premiums is received in advance of cash outflow required
to settle claims, we accumulate funds that we invest. At March 31, 2004, we had
$2.5 billion in investments compared with $2.4 billion at December 31, 2003. Our
investment program is structured with staggered maturities so that liquidation
of available-for-sale debt securities should not be necessary in the ordinary
course of business.

Total assets increased 5%, or $169.4 million, at March 31, 2004 from December
31, 2003. Invested assets increased $110.5 million due to net purchases of $74.9
million primarily funded by $55.2 million of operating cash flow and a $34.8
million increase in net unrealized gains on the portfolio. Increased premium
volume drove increases in premium receivables of $51.6 million and deferred
policy acquisition costs of $12.2 million. Reinsurance recoverable on paid
losses and loss expenses increased 43% or $3.3 million. The increase in the
reinsurance recoverable from the December 31, 2003 balance is primarily due to
an increase of $2.3 million for New Jersey Homeowners Quota Share and of $1.2
million due for the New Jersey Unsatisfied Claims Judgment Fund (UCJF). New
Jersey Homeowners Quota Share balance increased due to normal activity for the
first quarter of 2004. UCJF recovery collections in the first quarter of 2004
were somewhat slower than in the prior periods primarily due to the transfer of
the administration of the fund from UCJF to the New Jersey Property Liability
Insurance Guaranty Association.

Total liabilities increased 4%, or $118.8 million, at March 31, 2004 from
December 31, 2003. Loss and loss expense reserves increased $33.2 million as a
result of increased new business written. Increased premium volume is primarily
responsible for the increase in unearned premium reserves of $58.4 million.
Deferred federal income tax liability increased $13.8 million from $12.7 million
at December 31, 2003 to $26.5 million at March 31, 2004 primarily due to the
increase in unrealized gains in the debt and equity portfolios. Commissions
payable decreased $12.5 million at March 31, 2004 from December 31, 2003 which
was mainly attributable to the payment of the 2003 contingent commission in the
first quarter of 2004 offset by increases in commissions payable due to
increased premium volume. Other liabilities increased $25.4 million primarily
due to the increase in securities payable of $21.2 million at March 31, 2004
from December 31, 2003.

Total stockholders' equity increased 7%, or $50.7 million at March 31, 2004
compared to December 31, 2003. Additional paid in capital increased $16.3
million primarily from a $10.5 million increase related to restricted stock
grants, $2.9 million from stock option exercises, $1.3 million from tax
deductions related to stock compensation, $0.9 million from shares sold under
the agent stock purchase program and $0.5 million from shares sold under the
dividend reinvestment plan. Retained earnings increased $22.8 million due to net
income of $27.5 million offset by shareholder dividends of $4.7 million.
After-tax unrealized gains on our investment portfolio accounted for the $22.6
million increase in accumulated other comprehensive income. As an offset to
stockholders' equity, unearned stock compensation and notes receivable from
stock sales increased $9.3 million or 98% compared to December 31, 2003. This is
due to the issuance of the 2004 restricted stock grants in the first quarter.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

We have identified the policies below as critical to our business operations and
the understanding of our results of operations. For a detailed discussion of the
application of these and other accounting policies, see Item 8. "Financial
Statements and Supplementary Data," Note 2 to our consolidated financial
statements on pages 50 through 55 of our Annual Report on Form 10-K for the year
ended December 31, 2003. Note that our preparation of the unaudited interim
consolidated financial statements requires us to make estimates and assumptions
that affect the reported amount of assets and liabilities, disclosure of
contingent assets and liabilities at the date of our financial statements, and
the reported amounts of revenue and expenses during the reporting period. There
can be no assurance that actual results will not differ from those estimates.

RESERVES FOR LOSSES AND LOSS EXPENSES

Significant periods of time can 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 and loss expenses, insurers
establish reserves as balance sheet liabilities representing estimates of
amounts needed to pay reported and unreported net losses and loss expenses. As
of March 31, 2004 and December 31, 2003, the Company had accrued $1.6 billion of
loss and loss expense reserves.

When a claim is reported to an insurance subsidiary, its claims personnel
establish a "case reserve" for the estimated amount of the ultimate payment. The
amount of the reserve is primarily based upon a case-by-case evaluation of the
type of claim involved, the circumstances surrounding each claim and the policy
provisions relating to the type of losses. The estimate reflects the informed
judgment of such personnel based on general insurance reserving practices, as
well as the experience and knowledge of the claims person. Until the claim is
resolved, these estimates are revised as deemed necessary by the responsible
claims personnel based on subsequent developments and periodic reviews of the
cases.

In accordance with industry practice, we maintain, in addition to case reserves,
estimates of reserves for losses and loss expenses incurred but not yet reported
(IBNR). We project our estimate of ultimate losses and loss expenses at each
reporting date. The difference between: (i) projected ultimate loss and loss
expense reserves and (ii) case loss reserves and loss expense reserves thereon
are carried as the IBNR reserve. By using both estimates of reported claims and
IBNR determined using generally accepted actuarial reserving techniques, we
estimate the ultimate net liability for losses and loss expenses. We have
established a range of reasonably possible IBNR losses for non-environmental net
claims of approximately $661.5 million to $818.4 million at December 31, 2003. A
range has not been established at March 31, 2004, because management believes it
would not be meaningful. A low and high reasonable IBNR selection was derived
primarily by considering the range of indications calculated using standard
actuarial

                                       21


techniques. Such techniques assume that past experience, adjusted for the
effects of current developments and anticipated trends, are an appropriate basis
for predicting future events. Our net carried IBNR reserves for
non-environmental claims, including loss expense reserves, were $769.3 million
at March 31, 2004 and $733.7 million at December 31, 2003. The ultimate actual
liability may be higher or lower than reserves established. We do not discount
to present value that portion of our loss and loss expense reserves expected to
be paid in future periods. However, the loss reserves include anticipated
recoveries from salvage and subrogation.

Reserves are reviewed by both internal and independent actuaries for adequacy on
a periodic basis. Beginning in 2003, we began using independent actuaries to
certify the adequacy of our reserves. When reviewing reserves, we analyze
historical data and estimate the impact of various factors such as: (i) per
claim information; (ii) Company and industry historical loss experience; (iii)
legislative enactments, judicial decisions, legal developments in the imposition
of damages, and changes in political attitudes; and (iv) trends in general
economic conditions, including the effects of inflation. This process assumes
that past experience, adjusted for the effects of current developments and
anticipated trends, is an appropriate basis for predicting future events. There
is no precise method, however, for subsequently evaluating the impact of any
specific factor on the adequacy of reserves because the eventual deficiency or
redundancy is affected by many factors.

Included in the loss and loss expense reserves on the consolidated balance
sheets are amounts for environmental claims, both asbestos and non-asbestos.
These claims have arisen primarily under older policies containing exclusions
for environmental liability which certain courts, in interpreting such
exclusions, have determined do not bar such claims. The emergence of these
claims is slow and highly unpredictable. Since 1986, policies issued by the
Insurance Subsidiaries have contained a more expansive exclusion for losses
related to environmental claims. Our asbestos and non-asbestos environmental
claims have arisen primarily from exposures in municipal government, small
commercial risks and homeowners policies.

IBNR reserve estimation for environmental claims is often difficult because, in
addition to other factors, there are significant uncertainties associated with
critical assumptions in the estimation process such as average clean-up costs,
third-party costs, potentially responsible party shares, allocation of damages,
insurer litigation costs, insurer coverage defenses and potential changes to
state and federal statutes. However, management is not aware of any emerging
trends that could result in future reserve adjustments. Moreover, normal
historically-based actuarial approaches are difficult to apply because relevant
history is not available. In addition, while models can be applied, such models
can produce significantly different results with small changes in assumptions.
As a result, management does not calculate a specific environmental loss range,
as it believes it would not be meaningful.

After taking into account all relevant factors, we believe that the reserve for
net losses and loss expenses at March 31, 2004, is adequate to provide for the
ultimate net costs of claims incurred as of that date. Establishment of
appropriate reserves is an inherently uncertain process and there can be no
certainty that currently established reserves will prove adequate in light of
subsequent actual experience.

PREMIUM REVENUE

Net premiums written equal direct premiums written, plus assumed premiums less
ceded premiums. All three components of net premiums written are recognized in
revenue over the period that coverage is provided. The vast majority of our net
premiums written have a coverage period of twelve months. This means we record
1/12 of the net premiums written as earned premium each month, until the full
amount is recognized. When premium rates increase, the effect of those increases
would not immediately affect earned premium. Rather, those increases will be
recognized ratably over the period of coverage. Unearned premiums and prepaid
reinsurance premiums, which are recorded on the consolidated balance sheets,
represent that portion of premiums written that are applicable to the unexpired
terms of policies in force.

DEFERRED POLICY ACQUISITION COSTS

Policy acquisition costs, which include commissions, premium taxes, fees, and
certain other costs of underwriting policies, are deferred and amortized over
the same period in which the related premiums are earned. Deferred policy
acquisition costs are limited to the estimated amounts recoverable after
providing for losses and loss expenses that are expected to be incurred, based
upon historical and current experience. Anticipated investment income is
considered in determining whether a premium deficiency exists. The Company
continually reviews the methods of making such estimates and establishing the
deferred costs, and any adjustments therefrom are made in the accounting period
in which the adjustment arose.

OFF-BALANCE SHEET ARRANGEMENTS, CONTRACTUAL OBLIGATIONS AND CONTINGENT
LIABILITIES AND COMMITMENTS

At March 31, 2004 and 2003, the Company did not have any relationships with
unconsolidated entities or financial partnerships, such as entities often
referred to as structured finance or special purpose entities, which would have
been established for the purpose of facilitating off-balance sheet arrangements
or for other contractually narrow or limited purposes. As such, the Company is
not exposed to any financing, liquidity, market or credit risk that could arise
if the Company had engaged in such relationships.

Our future cash payments associated with contractual obligations pursuant to
operating leases for office space and equipment, senior convertible notes,
convertible subordinated debentures and notes payable have not materially
changed since December 31, 2003. We expect to have the capacity to repay and/or
refinance these obligations as they come due.

                                       22


The senior convertible notes have a contingent conversion feature that allows
conversion of the notes when the stock price has maintained a 20% premium to the
conversion price of $29.29, or $35.15, for 20 of 30 consecutive trading days
ending on the last trading day of such calendar quarter. As this contingency has
been met as of March 31, 2004, on any business day in the second quarter of
2004, the holders may surrender notes for conversion into shares of common
stock, or cash, at the Company's option. As this condition has been met, 3.9
million shares have been added to our diluted earnings per share calculation. We
expect to have the capacity to repay and/or refinance all of these obligations
as they come due.

We currently have available revolving lines of credit amounting to $45.0
million, under which no balances are outstanding as of either March 31, 2004 or
December 31, 2003. We have issued no guarantees on behalf of others and have no
trading activities involving non-exchange traded contracts accounted for at fair
value. We have no material transactions with related parties other than those
disclosed in Item 8. "Financial Statements and Supplementary Data", Note 17 to
our consolidated financial statements on page 73 of the 10-K section of our
Annual Report to Shareholders for the year ended December 31, 2003.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There have been no material changes in the information about market risk set
forth in our Annual Report on Form 10-K for the year-ended December 31, 2003.

ITEM 4. CONTROL AND PROCEDURES

An evaluation was carried out under the supervision and with the participation
of Selective's management, including its Chief Executive Officer and Chief
Financial Officer, of the effectiveness of the disclosure controls and
procedures (as defined in Rules 13a-15(e) of the Exchange Act) as of the end of
the period covered by this report. Based on that evaluation, the Chief Executive
Officer and Chief Financial Officer concluded that the disclosure controls and
procedures were effective as of the end of the period covered by this report.

No change in the Company's internal control over financial reporting (as defined
in Rule 13a-15(f) of the Exchange Act) occurred during the Company's first
fiscal quarter that materially affected, or is reasonably likely to materially
affect, the Company's internal control over financial reporting.

PART II OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS -

         On May 21, 2003, a purported class action was brought by several health
         care providers in the Superior Court of New Jersey, Law Division -
         Camden County, against Consumer Health Network Plus, LLC, Alta
         Services, LLC (Alta) and Selective Insurance Company of America, wholly
         owned subsidiaries of Selective, together with ten other unrelated
         defendants. The plaintiffs purport to represent a class of all New
         Jersey health care providers, except hospitals, who had bills for their
         services paid from personal injury protection benefits under New Jersey
         automobile insurance policies and whose payments were reduced pursuant
         to a preferred provider organization discount schedule. The lawsuit
         alleges that the defendants breached participating provider agreements
         and insurance policies and were unjustly enriched. We are vigorously
         defending this action, and the Company and the other defendants filed a
         Motion to Dismiss. A hearing was held on the Motion and the Court
         ordered the plaintiffs to amend their complaint by March 10, 2004. On
         March 10, 2004 the plaintiffs filed an amended complaint, wherein Alta
         was dropped as a defendant. All defendants expect to file a Motion to
         Dismiss the amended complaint on or about May 14, 2004. Since the suit
         remains in its early stages, management cannot at this time provide a
         meaningful estimate or range of estimates of a potential loss, if any.
