Item 2.03.  Creation of a Direct Financial Obligation or an Obligation under
            an Off-Balance Sheet Arrangement of a Registrant

On September 27, 2004 the Registrant amended its Credit Agreement dated as
of November 6, 2003 with a syndicate of five banks.  The amendment extended
the term of the Company's unsecured $150 million revolving credit facility
(the Credit Facility) for one year, to mature in November 2007.  The
amendment also revised the pricing schedule for the Credit Facility and
restated certain covenants effective with the issuance of the Company's 6
percent Subordinated Debentures due 2014.  These Subordinated Debentures are
expected to be issued October 26, 2004.  Following the amendment, borrowings
under the Credit Facility bear interest, at the Company's option, at (i)
LIBOR plus a variable premium or (ii) the greater of Prime or the Federal
Funds rate plus .50 percent.  LIBOR advances may be based upon the one, two,
three, or six-month LIBOR.  The variable premium over LIBOR is based on
certain financial ratios, and can range from 37.5 to 67.5 basis points.
Additionally, a facility fee is payable quarterly on the total commitment
and varies from 12.5 to 20.0 basis points based upon the Company's
capitalization ratio.  Availability of funds under the Credit Facility is
reduced by the amount of certain outstanding letters of credit.

Borrowings under the Agreement require the Company, among other things, to
maintain certain minimum levels of net worth and meet certain minimum
financial ratios.

A copy of the amendment is attached as Exhibit 4.1.
