ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

On August 8, 2005, James River Group, Inc. (the "Company") entered into an
Underwriting Agreement (the "Underwriting Agreement") with Keefe, Bruyette &
Woods, Inc., as representative (the "Representative") of the several
underwriters named therein (the "Underwriters"), in connection with the
Company's initial public offering.

The Underwriting Agreement provides for, among other things, the sale by the
Company of an aggregate of 5,110,600 shares of the Company's common stock,
including up to 666,600 shares subject to the Underwriters' 30-day
over-allotment option. The Company made certain representations and warranties
and agreed that it would not offer, sell or register under the Securities Act of
1933 shares of its common stock or securities convertible into or exchangeable
or exercisable for such shares (except for common stock issuable upon the
exercise of options), without the prior written consent of the Representative
for a period of 180 days after August 8, 2005, the date of the final prospectus
related to the offering, with certain exceptions specified in the Underwriting
Agreement. Similarly, the Company's executive officers and directors agreed that
they will not, other than as contemplated by the related prospectus, offer,
sell, contract to sell, pledge or otherwise dispose of shares of the Company's
common stock or securities convertible into or exchangeable or exercisable for
any such shares, or enter into a transaction that would have the same effect, or
enter into any swap, hedge or other arrangement that transfers, in whole or in
part, any of the economic consequences of ownership of the Company's common
stock, without, in each case, the prior written consent of the Representative
for a period of 180 days after August 9, 2005, subject to various exceptions
specified in the Underwriting Agreement and relevant lock-up agreements. The
Company also agreed to indemnify the Underwriters against certain liabilities 
under the Securities Act.

A copy of the Underwriting Agreement is filed as Exhibit 1.1 hereto and is
incorporated by reference herein. The description of the Underwriting Agreement
contained herein is qualified in its entirety by the full text of such exhibit.

ITEM 5.03 AMENDMENTS TO ARTICLES OF INCORPORATION OR BYLAWS; CHANGE IN FISCAL
YEAR.

On August 9, 2005, the Company filed with the Secretary of State of the State of
Delaware the Third Amendment to the Second Amended and Restated Certificate of
Incorporation of the Company (the "Amendment"). The Amendment is immediately
effective. The Amendment increased the Company's authorized capital stock to
105,000,000 shares, (i) 100,000,000 of which is common stock, $.01 par value per
share (the "Common Stock"), and (ii) 5,000,000 of which is preferred stock, $.01
par value per share. In addition, the Amendment effected a 10-for-1 split of the
Company's outstanding Common Stock.
