ALLMERICA FINANCIAL CORPORATION ANNOUNCES
                      IMPLEMENTATION OF GUARANTEED MINIMUM
                          DEATH BENEFIT HEDGING PROGRAM
                          -----------------------------

                 RECEIVES APPROVAL FOR $25 MILLION DIVIDEND FROM
                            LIFE INSURANCE SUBSIDIARY


WORCESTER, Mass., December 4, 2003 - Allmerica Financial Corporation (NYSE: AFC)
today  announced  the  implementation  of a  hedging  program  for its  in-force
variable annuity policies with Guaranteed Minimum Death Benefit (GMDB) features.
The  company  also  noted  that its lead life  insurance  subsidiary,  Allmerica
Financial Life Insurance and Annuity Company, will pay a dividend of $25 million
to the company.

The  purpose  of the GMDB  hedging  program is to provide  the  company  with an
economic hedge against  increased GMDB claims which could arise from declines in
the equity  market below current  levels.  The program is designed to reduce the
volatility in statutory  capital levels from the effects of future equity market
movements,  but it does not hedge or reduce  the cost to the  company  from GMDB
costs at current levels.

The  program  utilizes a dynamic  hedging  approach  involving  exchange  traded
futures contracts.  Under the program,  hedge contracts are expected to generate
cash to fund  increases  in GMDB claims  resulting  from  declines in the equity
market.  Additionally,  the  program is designed  so that the  economic  benefit
resulting from a rising equity market is retained by the company.

The  dividend,  which  approximates  the  company's  after-tax  obligations  for
interest on its senior debentures and Capital Securities in 2004,  combined with
existing  cash,  is sufficient to fund holding  company  obligations  throughout
2004. Accordingly,  the company does not expect to take any dividends out of its
property and casualty  companies next year. The company will use these funds for
general business purposes, principally debt service.

"Over the past year our significant capital enhancement actions have established
a strong  statutory  capital position and solid risk based capital ratios in our
life insurance  subsidiaries,"  said Frederick H. Eppinger,  Jr.,  president and
chief  executive  officer of Allmerica.  Eppinger  added,  "Our new GMDB hedging
program represents  another  significant step in our on-going efforts to protect
and maximize the embedded value of our life insurance subsidiaries."

Eppinger also noted,  "The  availability  of a dividend from the company's  life
insurance   subsidiary   underscores   the   strength  of  the  life   insurance
subsidiaries."

company's  new  hedging  program  on  December  5 at  8:30  a.m.  Eastern  Time.

the  anticipated  impact  and  cost  of  the  GMDB  hedging  program  constitute
forward-looking  statements which will depend on, among other things, the future
performance  and  volatility  of the  equity  markets,  the  extent to which the
performance of the various  hedging  instruments  correlates with the investment
performance of the underlying annuity sub-accounts,  the continued  availability
of equity index futures and redemption  and mortality  patterns in the company's
annuity contracts.
