Item 1.01  Entry into a Material Definitive Agreement

Upon recommendation of the Compensation  Committee,  the Board of Directors at a
meeting  held  on  March  15,  2005,   voted  to  adjust  the  compensation  for
non-management  directors,  as set forth below. Such changes are to be effective
for the  period  beginning  immediately  following  the 2005  Annual  Meeting of
Shareholders  (scheduled  for May 17,  2005)  until the 2006  Annual  Meeting of
Shareholders.  Directors  who are employees of Allmerica  Financial  Corporation
(the "Company") or its subsidiaries receive no additional compensation for their
services as members of the Board.

Annual Retainer
---------------
For the  period  from the 2004  Annual  Meeting of  Shareholders  until the 2005
Annual Meeting,  directors received an annual retainer  consisting of a grant of
1,500 shares of the Company's Common Stock and a cash payment of $20,245, which,
based on the date of grant of shares of Common Stock,  was intended to equate to
an annual retainer of approximately $73,000.

The annual retainer for 2005 is again intended to approximate $73,000;  however,
it is  intended  that the  retainer  will be paid 50% in shares of Common  Stock
based on the stock price on the date of grant (or as close as practicable to 50%
without the issuance of  fractional  shares) and the balance to be paid in cash.
Such  shares  will  be  granted  pursuant  to the  Non-Employee  Director  Stock
Ownership Plan.

Board Meeting Fees
------------------
Fees for attendance at meetings of the Board of Directors will be increased from
$1,500 to $2,200 per meeting.

Committee Chair Retainers
-------------------------
The annual retainer for chairing each of the Audit  Committee,  the Compensation
Committee and the Nominating and Corporate Governance Committee was changed from
$5,000 for each  committee,  to $10,000 for  chairing  the Audit  Committee  and
$7,500 for chairing each of the  Compensation  Committee and the  Nominating and
Corporate Governance Committee.

Committee Meeting Fees
----------------------
Fees for attendance at meetings of the Audit Committee,  Compensation  Committee
and the Nominating and Corporate  Governance  Committee were changed from $1,000
to $1,500 per meeting.

No change was made to the policy which provides that directors who are unable to
attend,  in person,  meetings of the Board or any  committee of which they are a
member, but who fully participate in any substantive meeting telephonically,  or
directors who participate in scheduled substantive telephone meetings,  are paid
a fee equal to one-half the regular Board or committee fee, as applicable.

Directors may defer receipt of their cash and stock compensation.  Deferred cash
amounts are accrued in a  memorandum  account  that is  credited  with  interest
derived from the  so-called  General  Agreement on Tariffs and Trade (GATT) Rate
(5.12% in 2004; 4.89% in 2005). At the election of each director, cash deferrals
of meeting fees and the retainer may be converted to Common Stock of the Company
at the time of  deferral,  with such stock  issued  pursuant  to the Amended and
Restated Non-Employee Director Stock Ownership Plan.
