4.  Company Obligated Mandatorily Redeemable Preferred Securities (8.71% 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 8.71% 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
8.71% 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 8.71% Capital Securities.

5.  Comprehensive Income

Other comprehensive income (loss) is composed of net unrealized holding gains
(losses) on securities arising during the period less reclassification
adjustments for gains included in net income. The related tax expense (benefit)
on net unrealized gains (losses) on securities was $(7.7) million and $(17.4)
million for the quarter and six months ended June 30, 1999 and $0.5 million and
$11.9 million for the same periods in 1998. The related tax expense on the
reclassification adjustments for gains included in net income was $0.7 million
and $3.2 million for the quarter and six months ended June 30, 1999,
respectively and $2.2 million and $3.4 million for the same periods in 1998.

6.  Acquisition

On January 15, 1999, the Company acquired Gryphon Holdings, Inc. and its
subsidiaries (Gryphon) as the result of the completion of a public tender offer.
The Company's second quarter and six month results for the period ending June
30, 1999 include Gryphon's results of operations since the date of acquisition.
The acquisition was accounted for using the purchase method of accounting. Total
consideration paid for Gryphon was approximately $145.7 million. The excess of
the purchase price over the fair value of the net tangible and identifiable
intangible assets acquired was recorded as goodwill and is being amortized using
the straight-line method over 20 years. The Company funded the transaction with
available cash of approximately $95.7 million and borrowings of approximately
$50 million. In addition the Company refinanced $55.0 million of Gryphon's
long-term debt.

7.  Segment Reporting Disclosures

The Company has five underwriting units focused on specific niches within the
Excess and Surplus Lines and Specialty Admitted markets. Excess and Surplus
Lines, Professional/Products Liability and Brokered Excess and Surplus Lines
write business in the Excess and Surplus Lines market and for purposes of
segment reporting are aggregated as one operating segment. Specialty Program
Insurance and Specialty Personal and Commercial Lines write business in the
Specialty Admitted market and for purposes of segment reporting are aggregated
as one operating segment. All investing activities are included in the Investing
operating segment.

The Company intends to significantly restructure Gryphon's operations and
expects that Gryphon's premium volume will decrease by 50% or more from
preacquisition levels. The Gryphon programs that the Company

                                       7



7. Segment Reporting Disclosures (continued)

intends to continue will be administered primarily by underwriting units in the
Excess and Surplus Lines operating segment. Gryphon's discontinued programs are
included in Other for purposes of segment reporting.

The Company considers many factors including the nature of the underwriting
units' insurance products, production sources, distribution strategies and
regulatory environment in determining how to aggregate operating segments.

Segment profit or loss for the Excess and Surplus Lines and the Specialty
Admitted operating segments is measured by underwriting profit or loss. Segment
profit for the Investing operating segment is measured by net investment income
and realized gains or losses.

The Company does not allocate assets to the Excess and Surplus Lines or the
Specialty Admitted operating segments for management reporting purposes. The
total investment portfolio is allocated to the Investing operating segment. The
Gryphon acquisition increased the total investment portfolio by approximately
$300 million in the first quarter of 1999. The Company does not allocate capital
expenditures for long-lived assets to any of its operating segments for
management reporting purposes.

====================================================================================================================================



Gross premium volume was $166.4 million for the second quarter and $300.4
million for the six month period in 1999 compared to $120.2 million and $217.5
million, respectively, for the same periods last year. The growth was primarily
the result of the Gryphon acquisition which added $31.5 million and $65.9
million to the Company's gross premium volume in the second quarter and six
month period of 1999. As the Company re-underwrites the Gryphon programs, the
Gryphon business is expected to decline significantly. The Company's core books
of business, excluding the effect of Gryphon, increased 12% in the second
quarter and 8% in the first six months of 1999. The Company has maintained its
underwriting standards at the expense of premium growth.

Excess and Surplus Lines second quarter gross premium volume was $37.0 million
compared to $34.6 million in 1998. For the six month period, gross premium
volume was $63.9 million compared to $59.6 million last year. The growth in both
periods was due to increased production in the casualty and inland marine
programs.

                                       10




Second quarter gross premium volume from Professional/Products Liability was
$35.6 million compared to $32.5 million a year ago. For the six month period,
gross premium volume advanced to $69.1 million from $63.2 million in 1998. For
both the quarter and six month periods, growth in the employment practices
liability and specified professions programs was partially offset by lower
production from other lines, including the medical malpractice program.

Premiums from Brokered Excess and Surplus Lines totaled $19.9 million in the
second quarter of 1999 compared to $17.2 million in 1998. For the six month
period, gross premium volume grew to $35.2 million from $31.9 million last year.
The increase in both periods was primarily due to higher gross premium volume in
the unit's property and excess and umbrella programs.

Gross premium volume for the Gryphon programs that the Company expects to
continue was $19.0 million in the second quarter of 1999 and $36.0 million for
the six month period. For the six month period of 1999, continuing program gross
premium volume consisted of $23.4 million of earthquake exposed California
property business which will become part of the Excess and Surplus Lines unit's
special property program, $6.5 million of professional liability business which
will become part of the Professional/Products Liability unit and $6.1 million of
casualty programs, most of which will be administered by the Brokered Excess and
Surplus Lines underwriting unit.

Specialty Program Insurance premiums declined to $17.5 million for the second
quarter and $34.4 million for the six month period in 1999 from $21.0 million
and $39.3 million, respectively, in 1998. Increased competition in the youth and
recreation program was partially offset by continued growth in the surety
program.

Specialty Personal and Commercial Lines premiums rose to $24.7 million in the
second quarter and $31.0 million in the six month period of 1999 from $14.0
million and $21.8 million, respectively, in 1998. The 1999 increase was
primarily due to the acquisition of a yacht program, including $7.3 million of
unearned premium at the date of acquisition, which added $13.5 million in gross
premium to the second quarter. The yacht program is expected to generate
approximately $15 million of gross premium volume in 1999.

Gross premium volume for the discontinued Gryphon programs was $12.4 million in
the second quarter and $29.9 million for the six month period in 1999. The
Company reviewed all of Gryphon's programs at the time of acquisition and
determined that certain programs were unprofitable and presented little
opportunity to generate future underwriting profits. The Company has
discontinued these programs and is working with the affected agents and brokers
to locate new markets for these risks.

Other gross premiums totaled $0.2 million in the second quarter of 1999 compared
to $0.9 million in the prior year. For the six month period in 1999, other gross
premiums totaled $0.8 million compared to $1.8 million a year ago. 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.

                                       11




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 decreased to 70% in the second
quarter of 1999 and 71% in the six month period compared to 78% for both periods
in the prior year. The decrease was due to low retentions on Gryphon's
California property program.

Total operating revenues for the second quarter of 1999 rose to $132.5 million
from $108.1 million in the prior year. For the six month period, operating
revenues rose to $271.0 million from $208.2 million in 1998.

====================================================================================================================================




Second quarter earned premiums were $108.3 million compared to $84.5 million in
1998. Six month earned premiums were $216.7 million compared to $163.4 million a
year ago. The growth in the second quarter was the result of $17.6 million of
earned premiums for Gryphon and $6.2 million of growth from existing operations.
For the six month period, the growth resulted from $42.2 million of Gryphon
earned premiums and $11.1 million of growth from existing operations.

Second quarter net investment income increased 26% to $21.7 million from $17.2
million in 1998. For the six month period, net investment income rose 28% to
$44.3 million from $34.7 million last year. The increases were the result of the
Gryphon acquisition which added $5.4 million and $10.2 million to net investment
income for the second quarter and six month period in 1999, respectively.

In the second quarter, the Company realized $2.0 million of investment gains
compared to $6.2 million of gains in 1998. For the six month period, realized
investment gains were $9.0 million compared to gains of $9.6 million for the
same period last year. Variability in the timing of realized and unrealized
investment gains and losses is to be expected.

Total operating expenses for the second quarter were $110.3 million compared to
$83.4 million in 1998. Total operating expenses for the six month period were
$223.2 million compared to $161.5 million a year ago. The increases resulted
primarily from the Gryphon acquisition.

Underwriting performance is measured by the combined ratio of losses and
expenses to earned premiums. For the second quarter and six month period, the
Company reported a combined ratio of 101% and 102% compared to a combined ratio
of 98% in both periods in 1998. The underwriting losses in 1999 were the result
of Gryphon's combined ratio of 128% and 124% for the second quarter and six
month period, respectively. Excluding Gryphon, the Company's 1999 combined ratio
was 95% and 96% for the quarter and six month period, respectively.

The second quarter and six month period loss ratio was 63% and 64%,
respectively, compared to 63% for both periods of 1998. For the six month
period, favorable loss development in the Excess & Surplus Lines operating
segment was more than offset by the higher loss ratio on Gryphon's discontinued
lines of business. The second quarter and six month period expense ratio was 38%
compared to 35% for both periods in 1998. The increase was due to Gryphon's
higher expense ratio. The Company is working agressively to reduce Gryphon's
expense ratio by leveraging corporate services and reducing costs to those
necessary to run Gryphon's operations on a smaller scale.

The Company's five underwriting units focus on specific niches within the Excess
and Surplus Lines and Specialty Admitted markets. Excess and Surplus Lines,
Professional/Products Liability and Brokered Excess and Surplus Lines write
business in the Excess and Surplus Lines market and for purposes of segment
reporting are aggregated as one operating segment. The Gryphon programs that the
Company intends to continue will be administered by underwriting units in the
Excess and Surplus Lines operating segment. Specialty Program Insurance and
Specialty Personal and Commercial Lines write business in the Specialty Admitted
market and for purposes of segment reporting are aggregated as one operating
segment.

The combined ratio for the Excess and Surplus Lines segment was 94% in the
second quarter of 1999 and 1998. For the six month period, the Excess and
Surplus Lines combined ratio decreased to 94% from 95% in 1998. The decrease in
the 1999 six month combined ratio was due to continued favorable loss
development, partially offset by higher acquisition costs. The combined ratio
for the Specialty Admitted segment decreased to 104% in the second quarter of
1999 from 108% in 1998. For the six month period, the Specialty Admitted
combined ratio decreased to 105% from 107% in 1998. The decrease in both periods
was the result of lower acquisition costs.

                                       13



Amortization of intangible assets was $1.4 million in the second quarter of 1999
compared to $0.5 million last year. For the six month period, amortization of
intangible assets was $2.6 million compared to $1.0 million in 1998. The
increase in both periods was primarily the result of goodwill from the Gryphon
acquisition which is being amortized over 20 years.

Interest expense was $6.5 million in the second quarter of 1999 compared to $5.1
million in 1998. Interest expense was $12.8 million for the six month period in
1999 compared to $10.2 million last year. In January 1999, the Company borrowed
$105 million under its $250 million revolving credit facility to complete the
acquisition of Gryphon. During July 1999, the Company repaid $20 million of the
$105 million of borrowings used to fund the purchase of Gryphon.

The Company's effective tax rate for the both periods of 1999 and 1998 was 24%
of income before income taxes.

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
second quarter of 1999, income from core underwriting and investing operations
increased to $11.9 million, or $2.10 per diluted share, from $11.3 million, or
$2.01 per diluted share, in 1998. For the six month period, income from core
underwriting and investing operations increased to $23.2 million, or $4.11 per
diluted share, from $22.4 million, or $3.96 per diluted share, in 1998. The
increase was due to higher net investment income, partially offset by
underwriting losses.

Second quarter 1999 net income decreased to $11.9 million from $14.9 million in
1998. For the six month period of 1999, net income was $26.6 million compared to
$27.8 million last year. The decrease was due to underwriting losses and lower
realized gains in 1999, partially offset by higher net investment income.
Comprehensive income for the second quarter of 1999 was a loss of $3.7 million,
or $0.66 per diluted share, compared to comprehensive income of $11.8 million,
or $2.08 per diluted share, in 1998. The decrease was the result of the net
decrease in unrealized gains of $2.76 per diluted share in 1999 compared to the
net decrease in unrealized gains of $0.56 per diluted share in 1998. For the six
month period, comprehensive income was a loss of $11.5 million, or $2.05 per
diluted share, compared to comprehensive income of $43.6 million, or $7.72 per
diluted share, last year. The decrease was the result of the net decrease in
unrealized gains of $6.77 per diluted share in 1999 compared to the net increase
in unrealized gains of $2.80 per diluted share in 1998.

Financial Condition as of June 30, 1999

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. To the extent that operating cash flows are negative
during any period of time, a portion of the Company's investment portfolio may
be liquidated to meet operating needs.

On January 15, 1999, the Company acquired Gryphon Holdings, Inc. and its
subsidiaries as the result of the completion of a public tender offer. The
Company's results for the second quarter and six month period ended June 30,
1999 include Gryphon's results of operations since the date of acquisition. The
acquisition was accounted for using the purchase method of accounting. Total
consideration paid for Gryphon was approximately $145.7 million. The excess of
the purchase price over the fair value of the net tangible and identifiable
intangible assets acquired was recorded as goodwill and is being amortized using
the straight-line method over 20 years. The Company funded the transaction with
available cash of approximately $95.7 million and borrowings of approximately
$50.0 million. In addition the Company refinanced $55.0 million of Gryphon's
long-term debt.

The Company's invested assets increased to $1.7 billion at June 30, 1999 from
$1.5 billion at December 31, 1998. The increase was primarily the result of the
Gryphon acquisition. The Company's unpaid losses and loss adjustment expenses
reserves and paid and unpaid reinsurance recoverables increased to $1.4 billion
and $441.1 million at June 30, 1999 from $933.8 million and $219.5 million,
respectively, at December 31, 1998. The increases were the result of the
purchase of Gryphon and Gryphon's historically higher dependence on reinsurance.

For the six month period ended June 30, 1999, the Company reported net cash used
by operating activities of $2.4 million, compared to net cash provided by
operating activities of $11.0 million for the same period in 1998. The decrease
in 1999 was the result of Gryphon's use of $20.2 million of operating cash for
the first six months of 1999. The Company continues to reunderwrite and
discontinue various Gryphon programs. As a result, Gryphon's operations are
expected to generate negative operating cash flows throughout 1999 which will
partially offset the operating cash flow generated by the Company's core
underwriting units.

For the six month period ended June 30, 1999, the Company reported net cash used
by investing activities of $48.0 million compared to $11.6 million in 1998. The
difference was primarily the result of the Gryphon acquisition.

As of June 30, 1999 and December 31, 1998, the unused balances available under
the Company's $250 million revolving credit facility totaled $145 million and
$250 million, respectively. Funds are available under the facility for general
corporate purposes. During July 1999, the Company repaid $20 million of the $105
million of borrowings used to fund the purchase of Gryphon. In addition the
Company has entered into an agreement to sell an unneeded Gryphon insurance
subsidiary as a shell for approximately $20 million. The transaction is expected
to close during the third quarter of 1999.

Shareholders' equity at June 30, 1999 was $413.9 million compared to $425.3
million at December 31, 1998. Book value per share was $74.02 at June 30, 1999
compared to $77.02 at December 31, 1998. The decrease in the six month period of
1999 was the result of the net decrease in unrealized gains of $38.1 million
partially offset by net income of $26.6 million.

Other Matters

Year 2000

The Year 2000 issue affects virtually all companies and organizations. Many
companies have existing computer applications which use only two digits to
identify a year in the date field. These applications were designed and
developed without considering the impact of the century change. If not corrected
these computer applications may fail or create erroneous results in the year
2000.

The Company's Year 2000 Strategy

The Company has created a Year 2000 team involving associates from all areas of
the organization and has charged them with implementing the Company's Year 2000
project. The team has been in place since September of 1997. The project's scope
includes all information technology (IT), both internally developed and
purchased from third parties, material vendors, producer and customer
relationships, and an assessment of the Company's underwriting exposure as a
result of the insurance products written by the Company's underwriting units. In
addition, the Company is evaluating the Year 2000 exposure to issuers included
as part of its investment portfolio.

The Company has completed all phases of its Year 2000 compliance project for its
material IT systems. The Company has also completed the assessment and
remediation phases for its ancillary IT systems and is currently in the testing
phase. The Company anticipates completion of all testing of its ancillary IT
systems by October 31, 1999.

The Company has been in contact with its material business partners to determine
their state of readiness with regard to the Year 2000 issue and the potential
impact on the Company. The Company has identified the following general
categories of business partners as material to the Company's ability to conduct
its operations: software, hardware and telecommunication providers, banks and
investment brokers, material holdings in the Company's investment portfolio,
insurance producers, reinsurers and reinsurance intermediaries, major insurance
clients and utilities. Where the Company has determined that the relationship
with a business partner is material to its ability to conduct normal operations,
the Company has sent letters to the business partner requesting an update on the
status of the business partner's Year 2000 initiative. Where deemed necessary,
the Company is following up with the business partner to obtain further
information. Based on the assurances of these business partners and the
Company's internal reviews of information provided, the Company has not
currently identified a material business partner that will be non-compliant.
However, there can be no assurances that all material business partners will be
compliant, and such noncompliance could have a material effect on the Company's
financial position and results of operations. The Company expects to complete
its review of material business partners by October 31, 1999.

The Company has conducted a comprehensive review of its underwriting guidelines
and has made the decision to exclude Year 2000 exposures from most insurance
policies. The Company began adding exclusions to policies in early 1998.
Additionally it is the Company's position that Year 2000 exposures are not
fortuitous losses and thus are not covered under insurance policies even without
specific exclusions. For these reasons, the Company believes that its exposure
to Year 2000 claims will not be material. However, as was the case with
environmental exposures, changing social and legal trends may create unintended
coverage for exposures by reinterpreting insurance contracts and exclusions. It
is impossible to predict what, if any, exposure insurance companies may
ultimately have for Year 2000 claims whether coverage for the issue is
specifically excluded or included.

The cost of the Company's Year 2000 project is estimated to be $1.0 million.
Approximately $0.5 million of this amount was incurred as of December 31, 1998.
The remainder of the estimated cost of the project is expected to be incurred
throughout 1999. All costs of the Year 2000 project have been expensed as
incurred.

                                       16




As all of its material IT systems were deemed Year 2000 compliant at December
31, 1998, the Company has not established a contingency plan for noncompliance
of its IT systems. At this time, the Company is not aware of any material
business partners that will not be Year 2000 compliant. If the Company becomes
aware of non-compliant business partners, one option will be to evaluate using
other vendors. In many instances the establishment of a contingency plan is not
possible or is cost prohibitive. In these situations, noncompliance by the
Company or its material business partners could have a material adverse impact
on the Company's financial position and results of operations.

Subsequent to the Company's acquisition of Gryphon in January 1999, the Company
began an assessment of Gryphon's material IT systems for Year 2000 compliance.
The Company has converted Gryphon's continuing business to the Company's Year
2000 compliant systems.

Quantitative and Qualitative Disclosures About Market Risk

Market risk is the risk of economic losses due to adverse changes in the
estimated fair value of a financial instrument as the result of changes in
equity prices, interest rates, foreign exchange rates and commodity prices. The
Company's consolidated balance sheets include assets and liabilities whose
estimated fair values are subject to market risk. The primary market risks to
the Company are equity price risk associated with investments in equity
securities and interest rate risk associated with investments in fixed
maturities. From time to time, equity prices and interest rates fluctuate
causing an effect on the Company's investment portfolio. The Company has no
direct commodity risk, and its exposure to foreign exchange risk is immaterial.

The Company's market risk disclosures at June 30, 1999 have not materially
changed from those identified at December 31, 1998.

"Safe Harbor" Statement

This is a "Safe Harbor" statement under the Private Securities Litigation Reform
Act of 1995. Certain statements contained herein are forward-looking statements
that involve risks and uncertainties. Future actual results may materially
differ from those in these statements because of many factors. For example, the
Company continues to significantly reorganize Gryphon's operations, and the
scope and impact of these changes cannot be fully determined at this time.
Insurance industry price competition has made it more difficult to attract and
retain adequately priced business. Changing legal and social trends can
adversely impact the adequacy of loss reserves. State regulatory actions can
impede the Company's ability to charge adequate rates and efficiently allocate
capital. The frequency and severity of natural catastrophes are highly variable.
Economic conditions and interest rate volatility can have significant impacts on
the market value of fixed maturity and equity investments. The business
community's state of readiness for the Year 2000, the readiness of the Company's
vendors and business partners and the Company's potential underwriting exposure
to Year 2000 claims are difficult to predict with any certainty. Accordingly,
the Company's premium growth, underwriting and investing results have been and
will continue to be potentially materially affected by these factors.
