THE  HANOVER  INSURANCE  GROUP,  INC.  ANNOUNCES  THE CLOSING OF THE SALE OF ITS
RUN-OFF VARIABLE LIFE INSURANCE AND VARIABLE ANNUITY BUSINESS
- --------------------------------------------------------------------------------

WORCESTER,  Mass.,  December 30, 2005 - The Hanover Insurance Group, Inc. (NYSE:
THG) announced  that it has closed the previously  announced sale of its run-off
variable  life  insurance  and variable  annuity  business to The Goldman  Sachs
Group,  Inc.  today.  In  conjunction  with this  closing,  The Hanover also has
received approval from the Massachusetts Division of Insurance for a dividend of
$40 million from its retained life  business,  First  Allmerica  Financial  Life
Insurance Company (FAFLIC).


"I am  pleased  we  have  closed  the  previously  announced  life  transaction,
monetizing  the  value  of our life  business  and  enabling  us to focus on our
property and casualty business," said Frederick H. Eppinger, president and chief
executive  officer of The Hanover  Insurance  Group,  Inc. "The sale provides us
with  greater  financial  flexibility  and  funding  for  our  share  repurchase
program."


Total proceeds are expected to be $347 million,  based on an estimated  purchase
price calculated as of November 30, 2005. Total proceeds include the $40 million
dividend  from FAFLIC and $17 million  additional  cash  available  from certain
non-insurance  subsidiaries.  Also included is $26 million of expected  proceeds
from the related Allmerica  Investment Trust (AIT) fund  reorganization and sale
of the AIT funds' investment  advisory  company,  which is scheduled to close on
January 6, 2006. Approximately $34 million of the total proceeds will be paid to
The Hanover over a three-year period beginning in 2006.


The final purchase price will be determined as of the December 30, 2005 closing;
accordingly,  the total  expected  proceeds of $347  million will be modified to
reflect  adjustments as of that date. The impact of this final adjustment is not
expected to be material.


The  transaction  is expected to result in a net after-tax loss on the sale that
is projected to be approximately  $457 million in 2005,  primarily as the result
of the write-down of non-cash  deferred  acquisition cost assets.  The after-tax
net loss  will also be  modified  to  reflect  the  December  30,  2005  closing
adjustments.


Additionally, as previously disclosed, the transaction will also result in a net
after  tax  loss  that is  projected  to be $16  million  in  2006,  related  to
transition services expenses and severance costs.


As previously announced, the company's Board of Directors has authorized a share
repurchase  program  of up to $200  million  funded  from  the  proceeds  of the
transaction. This program is currently expected to be substantially completed in
the first half of 2006.

Forward-Looking Statements

Certain statements in this release,  including  statements  estimating the total
proceeds,  the  expected  closing date for the AIT fund  reorganization  and the
expected completion date for the share repurchase  program,  are forward-looking
statements,  as that term is defined in the Private Securities Litigation Reform
Act of 1995.  There  are  certain  factors  that  could  cause  actual  results,
including the total  proceeds  from the  transaction  and the  completion of the
repurchase  program,  to differ  materially from those anticipated by this press
release.  These include:  (1) the successful and timely  consummation of the AIT
fund  reorganization and the sale of the AIT funds' investment  advisory company
(2) the uncertainties as to the gross proceeds to be received by THG,  including
the uncertainty as to the effects of the various purchase price adjustments, (3)
the  uncertainties  of the  successful  and timely  execution of the  repurchase
program  and the  continuation  thereof  in the event of  unanticipated  events,
market conditions or other  opportunities or needs for the deployment of capital
(4) the  uncertainties  of the  purchase  price hedge to  effectively  hedge the
purchase  price  as  currently   estimated  and  at  a  cost   consistent   with
expectations;  (5) the impact of  policyholder  surrenders on the purchase price
adjustment,  which are not  hedged;  (6) the impact of  contingent  liabilities,
including  litigation and regulatory matters,  assumed by the holding company in
connection with the transaction;  and (7) the statutory results of operations of
the Life Companies segment until close,  which will impact the statutory surplus
of AFLIAC and consequently the ultimate purchase price.

Forward-looking statements are not guarantees of future performance,  and actual
results could well differ materially.  Investors should consider these and other
risks and  uncertainties  in our  business  that may affect  future  performance
(including  Life  Companies  operations)  and  that  are  discussed  in  readily
