                Navigators Reports Record Third Quarter Results

     NEW YORK--(BUSINESS WIRE)--Oct. 30, 2006--The Navigators Group, Inc.
(NASDAQ:NAVG) reported record net income of $18,333,000 or $1.09 per share for
the 2006 third quarter compared to a net loss of $12,725,000 or $0.99 per share
for the 2005 third quarter. The 2006 third quarter results include a net
realized capital loss of $.01 per share and the 2005 third quarter results
include a net realized capital gain of $.02 per share. The 2005 third quarter
net loss includes $23,889,000 or $1.87 per share for after-tax net losses from
Hurricanes Katrina and Rita.

     Gross written premium and net written premium for the 2006 third quarter
were $221,667,000 and $119,037,000, respectively, increases of 18% and 57% from
the comparable 2005 period. Such 2006 third quarter increases were 21% and 31%,
respectively, when the effects of reinsurance reinstatement premiums for
hurricane losses are excluded from the 2005 gross and net written premium
amounts.

     Net income for the nine month period ended September 30, 2006 was
$51,956,000 or $3.09 per share compared to $8,254,000 or $0.64 per share for the
nine month period ended September 30, 2005. The results for the nine months
ended September 30, 2006 included a net realized capital loss of $.03 per share
and the results for the nine months ended September 30, 2005 included a net
realized capital gain of $.05 per share.

     Gross written premium and net written premium for the nine month period
ended September 30, 2006 were $737,816,000 and $391,711,000, respectively,
increases of 24% and 37% from the comparable 2005 periods.

     The combined loss and expense ratios for the 2006 third quarter and nine
month period were 87.4% and 87.9%, respectively, compared to 139.8% and 106.7%
for the comparable 2005 periods. The combined loss and expense ratios for the
2006 third quarter and nine month period were favorably impacted by 5.1 and 3.8
loss ratio points, respectively, by redundancies of prior year loss reserves.
Net paid loss ratios for the 2006 third quarter and nine month period were 35.9%
and 34.6%, respectively, compared to 39.1% and 39.3% for the comparable 2005
periods. The combined loss and expense ratios for the 2005 third quarter and
nine month period were increased by an aggregate 47.2 and 14.9 loss and expense
ratio points, respectively, for the net losses from Hurricanes Katrina and Rita.

     Stan Galanski, Navigators' Chief Executive Officer, commented, "We continue
to generate excellent underwriting results, reflecting what we believe to be a
well underwritten and properly priced book of business. Loss emergence patterns
continue to be favorable, particularly in Specialty and Professional Liability
business. Despite some softening in these two areas, we view the underwriting
environment as favorable. Our strong growth comes from the continued development
of several initiatives launched over the past two years."

     Galanski continued, "Market conditions in the marine business remain
favorable. With the lack of hurricane activity during the quarter, we hope that
marine and energy underwriters will recall the significant rate deficiencies in
pricing catastrophe exposures for energy risks made evident by last year's
storms, and will maintain the discipline required to profitably underwrite this
challenging niche."

     Net investment income for the 2006 third quarter and nine month period was
$14,691,000 and $41,244,000, respectively, both increases of 60% from the
comparable 2005 periods. The pre-tax investment yields for the 2006 third
quarter and nine month period were 4.5% and 4.4%, respectively, compared to 3.8%
for the comparable 2005 periods.

     Consolidated cash flow from operations for the 2006 third quarter and nine
month period ended September 30, 2006 was $76,043,000 and $92,715,000,
respectively, compared to $52,041,000 and $167,947,000 for the comparable 2005
periods. The 2006 nine month cash flow from operations was reduced by gross loss
payments of approximately $114,500,000 for 2005 hurricane losses and $19,900,000
for settled asbestos claims of which $67,200,000 and $10,689,000, respectively,
are due to be collected from reinsurers in subsequent accounting periods.

     Stockholders' equity was $527,515,000 or $31.59 per share at September 30,
2006 compared to $470,238,000 or $28.30 per share at December 31, 2005.
Statutory surplus of Navigators Insurance Company was $500,760,000 at September
30, 2006.

(1) Effective in 2006, the Company classifies its business into two
 underwriting segments, Insurance Companies and Lloyd's Operations,
 and a Corporate segment. Segment data for each of the two
 underwriting operations include allocations of revenues and expenses
 of Navigators Agencies and Holding Company expenses and related
 income tax amounts previously reported separately. Segment data for
 2005 and prior periods have been restated to reflect this change in
 segment reporting.
(2) Certain amounts included in gross written premium, commission
 expense and other income relate to inter-segment transactions,
 accordingly the sum for each segment does not agree to the totals
 shown in the table above.

(1) Effective in 2006, the Company classifies its business into two
 underwriting segments, Insurance Companies and Lloyd's Operations,
 and a Corporate segment. Segment data for each of the two
 underwriting operations include allocations of revenues and expenses
 of Navigators Agencies and Holding Company expenses and related
 income tax amounts previously reported separately. Segment data for
 2005 and prior periods have been restated to reflect this change in
 segment reporting.
(2) Certain amounts included in gross written premium, commission
 expense and other income relate to inter-segment transactions,
 accordingly the sum for each segment does not agree to the totals
 shown in the table above.
(3) The other operating expense ratio is adjusted to include
 commission and other income/(expense).
