Mr. Frederick Eppinger


Dear Fred:

     On behalf of the Board of Directors of  Allmerica,  I am pleased to confirm
our offer that you become Allmerica's  President and Chief Executive Officer. We
believe  that the Company has great  promise and that you are ideally  suited to
take full  advantage of that promise and we are delighted to welcome you back to
Central Massachusetts.

     I have been  authorized to propose a  compensation  package which we expect
you will  find to be both  fair and  attractive.  This  has  been  developed  in
consideration not only of your needs and expectations, but also in consideration
of compensation paid to other chief executive officers of competitive and larger
companies.

     We propose that you join the Company under the following arrangements:

     1.   Base Compensation. Seven Hundred Fifty Thousand Dollars ($750,000) per
          year, subject to adjustment effective April 1, 2004.

     2.   Performance  Bonus.  Targeted at one hundred  twenty percent (120%) of
          Base  Compensation,  based on meeting all performance goals, and up to
          two hundred forty percent (240%) of Base Compensation based on meeting
          all stretch goals,  subject in each case to the terms of the Company's
          Incentive Compensation Plan.

          With respect to the 2003  calendar  year,  you will be  guaranteed  an
          incentive   compensation   bonus  of  Four  Hundred  Thousand  Dollars
          ($400,000),  provided you are employed  with  Allmerica on the date in
          March 2004 when incentive compensation bonuses are regularly paid.


          While we have not refined target bonus  considerations,  they would be
          based on factors  such as  profitability,  combined  ratios,  ratings,
          development of a strategic business plan, plan execution, stock price,
          constituency  relationships,   management  team  building,   community
          relations, and the like.

     3.   Long-term  Incentive.  We would grant Three Hundred Thousand (300,000)
          Allmerica  non-qualified  stock options in  accordance  with our Stock
          Incentive  Plan,  with a strike price to be  determined  on the day of
          your first day of  employment.  Our  options  vest at a rate of 25% on
          each of the first two  anniversaries  of your employment date with the
          balance vesting on the third anniversary thereof. You will be eligible
          for  consideration of an additional grant at or about the time of your
          first anniversary of employment.

     4.   Clubs.  We would pay for your annual  membership  fee in the Worcester
          Club.

     5.   Severance.  In the event of a Change in Control of the Company causing
          termination  of your  employment,  the Company  would make a severance
          payment  to you in the  amount  of two times the sum of your then Base
          Compensation and target bonus. In the event of the termination of your
          employment by the Company  without  Cause,  independent of a Change in
          Control,  the  Company  would  pay  severance  equal  to (a)  if  such
          termination  occurs  within  the first  eighteen  (18)  months of your
          employment date, two times the sum of your then Base  Compensation and
          target  bonus,  and  (b)  if  such  termination  occurs  at  any  time
          thereafter,  one  times the sum of your  then  Base  Compensation  and
          target bonus.  In each event,  these  payments would be subject to you
          providing a general release and confidentiality,  non-solicitation and
          non-competition arrangements as described on the Attached.

     6.   Relocation.  The Company would pay for reasonable  costs of relocation
          for you and your family,  including temporary  accommodations for you,
          pending your family's relocation.  We encourage this relocation within
          six months, and encourage you to relocate to the City of Worcester.

     7.   Sign-on  Bonus and Stock  Purchase  Match.  The Company  would pay you
          Three  Hundred  Thousand  Dollars  ($300,000) on the first day of your
          employment  as a  sign-on  bonus;  provided,  however,  if you are not
          actively  employed  by the  Company for any reason on January 2, 2004,
          that you pay back  one-half  of such sum within  five (5) days of your
          termination date.

          In addition, to the extent you purchase shares of stock in the Company
          at any time beginning on your  employment  date and ending thirty (30)
          days thereafter,  we will match such shares, on a one-to-one basis, up
          to an  additional  expenditure  on our  part of Two  Hundred  Thousand
          Dollars ($200,000).


     8.   Other.  Our current plan is to announce your appointment on August 19,
          2003,  effective  September  8,  2003,  which  would  be  your  actual
          employment  date.  This offer and your election as President and Chief
          Executive  Officer is subject to approval  by the Board of  Directors,
          which I would  solicit prior to the  announcement  date. We would also
          plan to elect you as a director of the  Company,  effective  with your
          becoming  President and Chief  Executive  Officer.  We understand that
          there are no impediments such as  non-solicitation  or non-competition
          arrangements  which  would  impede  your  ability  to  carry  out your
          contemplated responsibilities at Allmerica.

     I look forward to working with you.

     My best wishes.

                                Very truly yours,

                               /s/Michael P. Angelini

embodied in writing or other  tangible  form. All originals and copies of any of
the foregoing,  however and whenever produced, shall be the sole property of the
Company. Upon the termination of your employment in any manner or for any reason
whatsoever, you shall promptly surrender to the Company all copies of any of the
foregoing,  together  with  any  documents,  materials,  data,  information  and
equipment  belonging  to or  relating  to the  Company's  business  and in  your
possession,  custody or control,  and you shall not thereafter retain or deliver
to any other person any of the foregoing or any summary or memorandum thereof.

unless  acting  with  the  Company's   express  written  consent,   directly  or
indirectly, during the term of your employment and for a period of two (2) years
thereafter,  in any  way,  hire,  solicit,  entice  away or  interfere  with the
Company's  contractual  relationships  with;  any customer,  vendor or supplier,

competitive  with those  offered by the Company;  or (b) except on behalf of and
for the  benefit of the  Company,  directly or  indirectly  and on behalf of any
other person or entity,  engage in  negotiations  with,  offer to sell  products

payments  previously  made.  These  remedies shall be in addition to, and not in
limitation  of,  any other  rights or  remedies  to which  Company  is or may be
entitled.  If any  part of any term or  provision  of this  Attachment  or Offer
Letter shall be held or deemed to be invalid,  inoperative or  unenforceable  to
any extent by a court of competent  jurisdiction,  such circumstance shall in no
way affect any other term or provision of this  Attachment  or the Offer Letter,
the  application  of such term or provision in any other  circumstances,  or the
validity or  enforceability  of this  Attachment or the Offer Letter;  provided,
however,  where practicable to bring effect to the provisions hereof, such court
shall modify the terms and  provisions  of this Offer Letter and  Attachment  to
make them  effective  to the maximum  extent  permitted  by law.  The  validity,
constructions and effect of the Offer Letter (including this Attachment) and any
actions taken under or relating  thereto shall be determined in accordance  with
the laws of the  Commonwealth of  Massachusetts  (without regard to conflicts of

actions relating to this Offer,  your employment or the Offer Letter  (including
this  Attachment),  venue  shall be  exclusively  had in state or federal  court
