4.  Company Obligated Mandatorily Redeemable Preferred Securities (Capital
    Securities)

On January 8, 1997 the Company arranged the sale of $150 million of 8.71%
Capital Securities issued under an Amended and Restated Declaration of Trust
dated January 13, 1997 (The Declaration) by Markel Capital Trust I (the Trust),
a statutory business trust sponsored and wholly-owned by Markel Corporation.
Proceeds from the sale of the Capital Securities were used to purchase
$154,640,000 aggregate principal amount of the Company's 8.71% Junior
Subordinated Deferrable Interest Debentures (the Debentures) due January 1,
2046, issued to the Trust under an indenture dated January 13, 1997 (the
Indenture). The Debentures are the sole assets of the Trust. The Company has the
right to defer interest payments on the Debentures for up to five years. The
Capital Securities and related Debentures are redeemable by the Company on or
after January 1, 2007. Taken together, the Company's obligations under the
Debentures, the Indenture, the Declaration and a guarantee made by the Company
provide, in the aggregate, a full, irrevocable and unconditional guarantee of
payments of distributions and other amounts due on the Capital Securities.

5.  Segment Information Disclosures

In June 1997 the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 131, Disclosures about Segments of an
Enterprise and Related Information. SFAS No. 131 is effective for years
beginning after December 15, 1997. This statement does not need to be applied to
interim financial statements in the initial year of its application. This
standard supersedes SFAS No. 14 and establishes new disclosure requirements
about products and services, geographic areas and major customers on an annual
and quarterly basis. The standard requires companies to disclose qualitative and
quantitative segment data on the basis that is used by management for evaluating
segment performance and deciding how to allocate resources. The Company is
currently evaluating what its meaningful reporting segments will be under SFAS
No. 131.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
        of Operations

Results of Operations
Three Months ended March 31, 1998 compared to Three Months ended March 31, 1997

The Company underwrites specialty insurance products and programs for niche
markets. Significant areas of underwriting include excess and surplus lines,
professional and products liability, specialty programs, specialty personal and
commercial lines, and brokered excess and surplus lines. Property and casualty
insurance for nonstandard and hard-to-place risks is underwritten by the excess
and surplus lines unit. Professional liability coverage is offered to physicians
and health professionals, insurance companies, directors and officers, attorneys
and architects and engineers. Special risk programs provide products liability
insurance for manufacturers and distributors and tailored coverages for other
unique exposures. In addition, employment practices liability coverage is
offered. Specialty program insurance includes coverage for camps, youth and
recreation, child care, health and fitness and agribusiness organizations, as
well as accident and medical insurance for colleges. The Company also
underwrites personal and commercial property and liability coverages for
watercraft, motorcycles, automobiles, mobile homes and dwellings. The brokered
excess and surplus lines unit writes hard-to-place, large general liability,
products liability and property accounts.

Following is a comparison of gross premium volume and earned premiums by
significant underwriting area:

- ------------------------------------------------------------------------------------------------------------------


Gross premium volume for the first quarter in 1998 was $97.4 million compared to
$98.1 million in the same period in the prior year. Aggressive competition in
many of the Company's markets contributed to decreased premium volume. The
Company has maintained its underwriting standards at the expense of premium
growth.

Excess and surplus lines gross premium volume was $25.0 million compared to
$28.6 million in 1997. Increased production in the inland marine program was
more than offset by decreases due to intense competition in the Markel special
property, casualty and property programs.

Premiums from professional/products liability insurance were $30.8 million
compared to $30.6 million a year ago. Growth in the employment practices and
specified professions programs was offset by lower production from other lines,
including financial institutions and directors' and officers' liability
programs.

Gross premiums from specialty program insurance were $18.3 million compared to
$18.5 million in the first quarter of 1997. Increased competition in the youth
and recreation and health and fitness programs contributed to the decrease.

Specialty personal and commercial lines premiums declined to $7.8 million from
$8.2 million in 1997. The division has decreased gross premium volume while it
restructures segments of its book of business.

                                       8



Premiums from Brokered Excess and Surplus Lines totaled $14.6 million in the
first quarter of 1998 compared to $11.1 million in 1997. The increase was due to
higher gross premium volume in the unit's casualty department mitigated by
decreased gross premium volume in the property department.

Other gross premiums totaled $0.9 million compared to $1.1 million in 1997.
Other gross premium volume primarily consisted of facultative reinsurance placed
by the Professional/Products Liability unit.

Currently many of the Company's products are being adversely affected by
increased competition and lower rates in the property and casualty market. The
Company does not intend to relax underwriting standards in order to sustain
premium volume. Further, the volume of premiums written may vary significantly
with the Company's decision to alter its product concentration to maintain or
improve underwriting profitability.

The Company enters into reinsurance agreements in order to reduce its liability
on individual risks and enable it to underwrite policies with higher limits. The
Company's net retention of gross premium volume increased to 79% in the first
quarter of 1998 compared to 77% in the prior year. The increase was primarily
due to a new reinsurance treaty structure in the Specialty Program Insurance
unit and higher retentions in the professional and products liability unit.

Total operating revenues rose to $100.1 million from $98.5 million in the prior
year. First quarter earned premiums were $78.9 million compared to $81.7 million
for the first quarter of 1997. The decrease was due to competitive market
conditions over the past several years which have resulted in a decline in gross
premium growth.

Net investment income increased 5% to $17.6 million in the first quarter from
$16.7 million a year ago. The increase was the result of operating cash flows
during 1997 which added to the Company's investment portfolio.

Realized gains were $3.4 million for the first quarter in 1998 compared to
realized losses of $0.6 million last year. Variability in the timing of realized
and unrealized investment gains or losses is to be expected.

Total operating expenses for the first quarter were $78.1 million compared to
$81.6 million in 1997. The decrease resulted primarily from lower variable
expenses associated with lower earned premiums.

Underwriting profitability is measured by the combined ratio of losses and
expenses to earned premiums. The Company reported a combined ratio of 98% in the
first quarter of 1998 compared to a combined ratio of 99% in 1997. The Company's
loss ratio was 63% compared to 64% in 1997. The 1998 loss ratio decreased due to
continued favorable loss reserve development and the absence of significant
winter weather property losses. The expense ratio was 35% in both periods.

In evaluating its operating performance, the Company focuses on core
underwriting and investing results before consideration of realized gains or
losses from the sales of investments and expenses related to the amortization of
intangible assets. Management believes this is a better indicator of the
Company's operating performance because it reduces the variability in results
associated with realized investment gains or losses and eliminates the impact of
accounting conventions which do not reflect current operating costs. For the
first quarter of 1998, income from core underwriting and investing operations
increased to $11.0 million, or $1.96 per diluted share, from $9.6 million, or
$1.71 per diluted share, in 1997. The increase was due to higher net investment
income supported by underwriting profitability.

The Company's effective tax rate for the first quarter of 1998 was 24% of income
before income taxes compared to 26% in the first quarter of 1997. The decrease
in 1998 was due to a larger portion of the Company's investment portfolio being
allocated to tax-exempt municipal securities.

First quarter 1998 net income rose 46% to $12.8 million from $8.8 million in
1997. The increase is due to increased underwriting profitability and higher
realized gains. Comprehensive income increased sharply to $31.9 million, or
$5.64 per diluted share, compared to comprehensive income of $3.1 million, or
$0.55 per diluted share in 1997. The change was primarily the result of
increased unrealized gains of $3.37 per diluted share in the first quarter of

1998 compared to unrealized losses of $1.01 per diluted share in 1997. Higher
net income in 1998 as compared to the first quarter of 1997 also contributed to
the increase in comprehensive income.

Financial Condition as of March 31, 1998

The Company's insurance operations collect premiums and pay current claims,
reinsurance commissions and operating expenses. Premiums collected and positive
cash flows from the insurance operations are invested primarily in short-term
investments and long-term bonds. Short-term investments held by the Company's
insurance subsidiaries provide liquidity for projected claims, reinsurance costs
and operating expenses.

For the three month period ended March 31, 1998, the Company reported net cash
used by operating activities of $0.1 million, compared to net cash provided by
operating activities of $9.5 million for the same period in 1997. The decrease
was due to various large claims payments and a decline in gross premium volume
in the first quarter of 1998. The Company currently expects positive operating
cash flow throughout the remainder of 1998.

For the three month period ended March 31, 1998, the Company reported net cash
used by investing activities of $0.5 million compared to $153.6 million in 1996.
The difference was primarily due to the Company's investment of the net proceeds
of the $150 million 8.71% Capital Securities offering during the first quarter
of 1997.

At March 31, 1998 the Company's fixed maturity and equity investments comprised
approximately 75% and 21% of total investments, respectively. The Company
expects variability in its realized and unrealized investment gains or losses.

In January 1997 the Company arranged the sale of $150 million of 8.71% Capital
Securities. The proceeds are primarily invested in short-term securities. These
short-term investments are earning lower net investment income than the
associated interest expense on the 8.71% Capital Securities. The Company
continues to evaluate long-term investment options for the proceeds that will
contribute to the Company's goal of 20% annual growth in book value per share.

As of March 31, 1998 and December 31, 1997, the unused balances available under
the Company's revolving credit facility totaled $150 million. In April 1998 the
Company arranged a $250 million, five year, revolving credit facility with a
group of banks which replaced the Company's existing $150 million credit
facility. Funds are available under the facility for general corporate purposes.

Shareholders' equity at March 31, 1998 was $389.1 million compared to $356.8
million at December 31, 1997. Book value per share rose to $70.75 at March 31,
1998 from $65.18 at December 31, 1997.
