             Report of Independent Registered Public Accounting Firm


To the Administrative Committee of
Great West Casualty Company Profit Sharing Plan:

In our opinion, the accompanying statements of net assets available for benefits
and the  related  statements  of changes in net assets  available  for  benefits
present fairly, in all material respects,  the net assets available for benefits
of Great West Casualty  Company Profit Sharing Plan (the "Plan") at December 31,
2004 and 2003,  and the changes in net assets  available  for  benefits  for the
years then ended in conformity with accounting  principles generally accepted in
the United States of America.  These financial statements are the responsibility
of the Plan's  management.  Our responsibility is to express an opinion on these
financial  statements  based on our  audits.  We  conducted  our audits of these
statements in accordance  with the  standards of the Public  Company  Accounting
Oversight  Board  (United  States).  Those  standards  require  that we plan and
perform the audit to obtain  reasonable  assurance  about  whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements,  assessing the accounting  principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

Our audits  were  conducted  for the  purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental  schedule of assets held
for  investment  purposes at December 31, 2004 is  presented  for the purpose of
additional analysis and is not a required part of the basic financial statements
but is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure  under the Employee  Retirement  Income
Security Act of 1974. This  supplemental  schedule is the  responsibility of the
Plan's management.  The supplemental schedule has been subjected to the auditing
procedures  applied in the audits of the basic financial  statements and, in our
opinion,  is fairly  stated in all  material  respects  in relation to the basic
financial statements taken as a whole.

NOTE 1 - DESCRIPTION OF PLAN

The  following  brief  description  of the Great West  Casualty  Company  Profit
Sharing  Plan  (Plan)  is  provided  for  general  information   purposes  only.
Participants should refer to the Plan agreement for a more complete  description
of the Plan's provisions.

(a) General

The Plan is a defined  contribution  profit-sharing plan sponsored by Great West
Casualty Company (the Company),  covering all eligible  employees of the Company
as well as its affiliates. The Plan is subject to the provisions of the Employee
Retirement Income Security Act of 1974 (ERISA), as amended from time to time.

(b) Contributions and Participant Accounts

Participants  may  contribute  1/2% to 15% of their annual wages to the Plan. In
2004 and 2003, the Company made matching  contributions to the Plan equal to 25%
of the first 6% of the employees' pre-tax contribution amount.  Participants may
elect  to have  their  contributions  invested  in any  one or more of  fourteen
separate  investment  funds.  The  Company  may also  contribute  an  additional
nonmatching  amount  out of its  current  or  accumulated  profits,  if any,  as
determined by the Company.

Each participant's  account is credited with the participant's  contribution and
an allocation of (a) the Company's contributions as described above and (b) Plan
earnings.  Allocations are based on participant account balances as defined. The
benefit to which a  participant  is entitled is the benefit that can be provided
from the participant's account.

(c) Eligibility and Vesting

Under the terms of the Plan, an employee shall become  eligible for inclusion in
the Plan 30 days following the first day he/she completes an hour of service and
upon  reaching  age  21.  An  employee   shall  become   eligible  for  employer
discretionary  contributions  upon reaching age 21 and after completion of 1,000
hours of service in any one Plan year,  beginning with date of hire. Minimum age
for vesting service is 18 years.

All employee and employer  matching  contributions  are immediately 100% vested.
Participants become fully vested in the value of the discretionary contributions
after 6 years of credited service.

NOTE 1 - DESCRIPTION OF PLAN, Continued

(d) Payment of Benefits

On  termination  of  service,  retirement,  or death a  participant  or  his/her
beneficiary  may elect to leave funds in the Plan or receive either a single-sum
payment or purchase of a single  premium  life annuity  contract.  Net assets at
December 31, 2004 and 2003,  include funds totaling  $4,923,285 and  $1,585,785,
respectively,  which  represent  the account  balance of retired and  terminated
participants  who have elected to leave the funds in the Plan upon retirement or
termination.

(e) Forfeitures

All  forfeitures  are  segregated  until the employee  has attained  break(s) in
service totaling five years. At that time forfeitures are allocated  pro-rata to
each participant  account according to their respective  earnings for that year.
There were  unallocated  assets of  $601,651  and  $1,134,307,  respectively  at
December 31, 2004 and 2003, related to these forfeitures.


(f) Loans

Participants may elect to borrow from the Plan based upon specified  conditions.
A participant  may have two outstanding  loans at any time.  Minimum single loan
amount is $1,000.  In no case shall the aggregate amount loaned to a participant
exceed the lesser of the  following:  (a)  $50,000  reduced by the excess of the
highest  outstanding  balance of loans from the Plan  during the one year period
ending on the date before the date of the loan to the participant; or (b) 50% of
the participant's vested interest.  The interest rate on such loans is the prime
rate as declared in the Wall Street  Journal plus 1%.  Principal and interest is
repaid ratably through bi-weekly payroll deductions.

(g) Administrative Expenses

The Company  provides  administrative  support for the Plan and pays for certain
administrative and trustee fees.

The preparation of financial statements in conformity with accounting principles
generally  accepted in the United States of America requires  management to make
estimates  and  assumptions  that  affect  the  reported  amounts  of net assets
available for benefits and  disclosure of contingent  assets and  liabilities at
the date of the financial statements and the changes in net assets available for
benefits  during the reporting  period.  Actual  results could differ from those
estimates.

(c) Risks and Uncertainties

The Plan provides for various  investment  options in any combination of stocks,
bonds, fixed income securities,  mutual funds, and other investment  securities.
Investment  securities  are exposed to various  risks,  such as  interest  rate,
market and credit.  Due to the level of risk associated with certain  investment
securities  and the level of  uncertainty  related  to  changes  in the value of
investment securities, it is possible that changes in risks in the near

term would  materially  affect  participants'  account  balances and the amounts
reported in the statement of net assets available for benefits and the statement
of changes in net assets available for benefits.

(d) Investments

At  December  31, 2003 the Plan had a contract  with  Connecticut  General  Life
Insurance Company (CIGNA). On April 1, 2004 Prudential Financial,  Inc. acquired
CIGNA and formed Prudential Retirement Insurance and Annuity Company (PRIAC). As
of this date,  the  fifteen  pooled  investment  funds  remain the same with the
exception of the fund name changes. The Plan entered into a contract with PRIAC,
where  PRIAC  maintains  contributions  in a  contractholder's  account and such
contributions   are  allocated  to  fifteen  separate  pooled  investment  funds
according to participant  elections.  The accounts are credited with earnings on
the underlying investments and charges for Plan benefits paid and deductions for
investment  expenses,  risk, profit and annual management fees charged by PRIAC.
The pooled  separate  accounts are included in the financial  statements at fair
value.  Realized  investment gains and losses in the separate pooled  investment
funds are recognized in the year of sale.

The  PRIAC  Guaranteed  Long - Term  Account,  which is a  general  account,  is
included  in the  financial  statements  at  contract  value,  (which  represent
contributions  made under the contract,  plus  earnings,  less  withdrawals  and
adminstrative expenses) because they are fully benefit responsive.  For example,
participants  may  ordinarily  direct the  withdrawal  or  transfer  of all or a
portion of their  investment at contract  value.  There are no reserves  against
contract  value for credit risk of the contract  issuer or  otherwise.  The fair
value of the investment  contract at December 31, 2004 and 2003 was  $18,016,308
and $17,662,263,  respectively.  The average yield and crediting  interest rates
were approximately 3.25% and 3.3% for 2004 and 2003, respectively. The crediting
interest  rate is  based  on an  agreed-upon  formula  with  the  issuer  and is
evaluated every six months.  Investment income is recorded on the accrual basis.
Dividends on stocks are  credited to income on the  ex-dividend  date.  Realized
investment gains and losses in the general account are recognized in the year of
sale.

Old  Republic  International  Corporation  (ORI)  common stock is stated at fair
value based on quoted closing market value on the last business day of the year.
The Plan  presents  in the  statements  of changes in net assets  available  for
benefits the net appreciation  (depreciation) in the fair value of the ORI stock
account,  which  consists  of the  realized  gains or losses and the  unrealized
appreciation (depreciation) of this investment.

(e) Benefit Payments

Benefit payments to participants are recorded upon distribution.
