    FREEHOLD, N.J.--(BUSINESS WIRE)--Nov. 10, 2006--National Atlantic
Holdings Corporation (Nasdaq: NAHC), a provider of specialized
property-casualty insurance products and related insurance services
based in Freehold, N.J., today announced financial results for the
third quarter and nine months ended September 30, 2006.

    Net income for the three months ended September 30, 2006 was $4.4
million or $0.38 per share (diluted), compared with a net loss of $1.6
million or $0.15 per share (diluted) for the three months ended
September 30, 2005. Net income for the nine months ended September 30,
2006 was $11.4 million or $0.99 per share (diluted), compared with net
income of $4.3 million or $0.47 per share (diluted) for the nine
months ended September 30, 2005.

    Diluted earnings per share for the three months ended September
30, 2006 were based on weighted average common shares (diluted) of
11,500,074 compared with weighted average common shares (diluted) of
11,480,222 for the three months ended September 30, 2005. Diluted
earnings per share for the nine months ended September 30, 2006 were
based on weighted average common shares (diluted) of 11,466,542
compared with weighted average common shares (diluted) 9,108,389 for
the nine months ended September 30, 2005. Book value per share for the
nine months ended September 30, 2006 was $13.32, compared with $12.34
for the year ended December 31, 2005, representing an 8% growth in
book value.

    Total revenues for the three months ended September 30, 2006
decreased by $2.8 million, or 5.9%, to $44.4 million from $47.2
million for the three months ended September 30, 2005. Total revenues
for the nine months ended September 30, 2006 decreased by $12.2
million, or 8.5%, to $130.6 million from $142.8 million for the nine
months ended September 30, 2005.

    "During the third quarter, our Partner Agents added new policies
in virtually all of our lines of business - commercial, homeowners, as
well as private passenger automobile," said James V. Gorman, Chairman
and Chief Executive Officer. "We are pleased with the policy count
growth we are experiencing in all lines of business," he said.

    "The growth in earnings-per-share for the quarter was generated
primarily by core growth in our insurance operations and is a
reflection of our partner agents' marketing efforts, as well as our
completion of the clean-up on books of business acquired through
replacement carrier transactions in prior years," said Frank J.
Prudente, Executive Vice President, Treasurer and Chief Accounting
Officer.

    "We have regained some of our customers lost to direct writers in
prior quarters," Mr. Gorman said. "Although the auto market in New
Jersey remains highly competitive, we feel that the level of
competition has stabilized," he said.

    Premiums

    Direct written premiums for the three months ended September 30,
2006 increased by $3.7 million, or 8.8%, to $45.6 million from $41.9
million in the comparable 2005 period. Direct written premiums for the
nine months ended September 30, 2006 decreased by $29.5 million, or
17.9%, to $135.5 million from $165.0 million in the comparable 2005
period. The increase was primarily due to new business generated by
our Partner Agents, offset by attrition of business acquired as part
of previous replacement carrier transactions.

    Net written premiums for the three months ended September 30, 2006
increased by $1.5 million, or 3.6%, to $43.4 million from $41.9
million in the comparable 2005 period. Net written premiums for the
nine months ended September 30, 2006 decreased by $30.4 million, or
19.2%, to $127.9 million from $158.3 million in the comparable 2005
period.

    Net earned premiums for the three months ended September 30, 2006
decreased by $3.6 million, or 8.3%, to $39.7 million from $43.3
million in the comparable 2005 period. Net earned premiums for the
nine months ended September 30, 2006 decreased by $15.4 million, or

period.
