  Net Income of $10.8 Million or $0.67 Per Diluted Share Before $0.04 Per Share
                 of Costs Associated With Announced Transaction

      CHAPEL HILL, N.C., Nov. 5 /PRNewswire-FirstCall/ -- James River Group,
Inc. (Nasdaq: JRVR) today announced financial results for the third quarter
ended September 30, 2007. The Company previously announced that it entered into
a definitive merger agreement under which a Bermuda-based holding company and
member of the D. E. Shaw group, a global investment management firm, would
acquire the Company. In connection with the proposed merger, during the third
quarter, the Company incurred $1.0 million in pre-tax costs ($619,000 after-tax
or $0.04 per diluted share) for legal, accounting and investment banking
services. On a year-to-date basis, the Company incurred $3.0 million in pre-tax
costs ($1.9 million after-tax or $0.12 per diluted share). See "Reconciliation
of Non-GAAP Measures" for a reconciliation of results presented herein as
adjusted to reflect these non-recurring costs to their comparable GAAP results.

      Highlights for the third quarter include:
      *     Net income in 2007 of $10.2 million, or $0.63 per diluted share
            ($10.8 million, or $0.67 per diluted share excluding the costs
            associated with the transaction with the D. E. Shaw group), compared
            to net income of $9.3 million, or $0.58 per diluted share in the
            third quarter of 2006;
      *     An annualized return on average stockholders' equity of 17.5%;
      *     A combined ratio of 85.0% (83.6% prior to the aforementioned
            transaction costs) compared to 83.2% for the third quarter of the
            prior year; and
      *     An underwriting profit of $10.0 million ($11.0 million prior to the
            transaction costs) compared to $9.7 million in the third quarter of
            the prior year.

      Highlights for the year-to-date, nine-month period ended September 30,
2007, include:
      *     Net income in 2007 of $29.5 million, or $1.82 per diluted share
            ($31.4 million, or $1.94 per diluted share prior to the transaction
            costs), compared to net income of $24.6 million, or $1.54 per
            diluted share for the same period in 2006;
      *     An annualized return on average stockholders' equity of 17.3%;
      *     A combined ratio of 85.0% (83.4% prior to the transaction costs)
            compared to 83.9% for the same period in 2006; and
      *     An underwriting profit of $28.5 million ($31.4 million prior to
            transaction costs) compared to $25.5 million for the same period in
            2006.



      Reported earnings per diluted share for the third quarter of 2007 were
$0.63 compared to $0.58 for the same period in 2006. Adjusted diluted earnings
per share absent the $1.0 million of transaction costs were $0.67 for the third
quarter of 2007 -- an increase of $0.09, or 15.5% over the same period in the
prior year. Diluted shares outstanding were 16.2 million for the three months
ended September 30, 2007 and exceeded those for the quarter ended September 30,
2006 of 16.0 million. Results for the quarter ended September 30, 2007 include
net after-tax favorable reserve development on prior accident years of direct
business written by the Company of $2.0 million. In the prior year, the
favorable reserve development on direct business written was $1.7 million
after-tax.

      Reported earnings per diluted share for the nine months ended September
30, 2007 were $1.82 compared to $1.54 for the same period in 2006. Adjusted
diluted earnings per share absent the $3.0 million of transaction costs were
$1.94 for the nine months ended September 30, 2007 -- an increase of $0.40, or
26.0% over the same period in the prior year. Diluted shares outstanding were
16.2 million for the nine months ended September 30, 2007 and exceeded those of
the same period of the prior year of 16.0 million. Results for the nine months
ended September 30, 2007 include net after-tax favorable reserve development on
prior accident years of direct business written by the Company of $5.8 million.
In the prior year, the favorable reserve development on direct business written
was $4.5 million after-tax.

      The Excess and Surplus Insurance segment's combined ratio was 78.6% and
77.6% for the quarter ended September 30, 2007 and 2006, respectively, and 79.5%
and 78.1% for the nine-month period ended September 30, 2007 and 2006,
respectively. Net after-tax favorable reserve development on prior accident
years on direct business written by this segment was $2.3 million and $1.7
million for the quarter ended September 30, 2007 and 2006, respectively. This
amount was $5.8 million and $4.4 million after-tax for the nine months ended
September 30, 2007 and 2006, respectively.

      The Workers' Compensation Insurance segment's combined ratio was 95.4% for
the third quarter of 2007. The combined ratio for the nine months ended
September 30, 2007 of 91.1% was significantly lower than the prior year's
combined ratio of 99.8% due to both lower losses and management of underwriting
and other expenses. Net after-tax reserve development on prior accident years of
direct business written by this segment included adverse development of $318,000
for the quarter ended September 30, 2007 and adverse development of $66,000 for
the same period in the prior year. For the nine months ended September 30, 2007
and 2006, net after-tax reserve development on prior accident years of direct
business written by this segment included adverse development of $48,000 and
favorable development of $91,000 respectively.

      The Company's net investment income for the quarter ended September 30,
2007 was $6.3 million, an increase from the $5.2 million for the quarter ended
September 30, 2006. For the nine months ended September 30, 2007, net investment
income was $18.0 million, an increase from the $13.7 million reported for the
same period in the prior year. At September 30, 2007, the Company held $4.3
million in par value of securitizations of alternative-A and sub-prime
mortgages, all of which are rated "AAA" by the established ratings agencies.

      J. Adam Abram, President and Chief Executive Officer, commented, "We are
pleased with our results despite increased competition which resulted in
pressure on pricing and premium volume. Annualized return on equity remains
attractive and our book value has increased to $15.78 per share."

      Mr. Abram added, "Our acquisition by a member of the D. E. Shaw group
continues on its expected course and is expected to close in early December. We
are pleased that we have such well-capitalized and committed partners as we go
forward."



      In light of the proposed transaction with a member of the D. E. Shaw
group, the Company is no longer providing guidance. On October 2, 2007, the
Company filed a definitive proxy statement with the Securities and Exchange
Commission containing information about the proposed transaction.

    RECONCILIATION OF NON-GAAP MEASURES

    The following table reconciles the underwriting profit by individual
    insurance segment and of the whole Company to consolidated income before
    taxes. We believe that these measures are useful to investors in evaluating
    the performance of our Company and its insurance segments because our
    objective is to consistently earn underwriting profits. We evaluate the
    performance of our insurance segments and allocate resources based primarily
    on underwriting profit of insurance segments. Our definition of underwriting
    profit of insurance segments and underwriting profit may not be comparable
    to that of other companies.

    Management believes that the presentation of underwriting profit, income
    statement, earnings per share amounts and combined ratio information both
    before and after the effects of the transaction costs incurred to date
    relating to the proposed transaction allow for better comparisons to prior
    periods. Management considers results both before and after the effects of
    the transaction costs in assessing performance. Management does not
    anticipate that additional costs for legal, accounting and investment
    banking services for such a transaction will be incurred in subsequent
    fiscal years. Assuming all conditions are met, the Company expects the
    transaction to close in early December.
