Dear Bob:

You and First  Allmerica  Financial  Life Insurance  Company (the "Company")have
mutually  agreed  to  terminate  your employment  relationship  pursuant to  the
terms and conditions set forth below.  This letter agreement  contains a release
and waiver of any potential claim arising out of your employment relationship or
the termination of your employment  relationship (the "Separation  Agreement" or
"Agreement"). It is important that you read and understand the following terms:

1.   Resignation:  You have resigned as President and Chief Executive Officer of
     the Allmerica Property & Casualty  Companies,  Inc. and any other titles or
     officer/director  positions  that  you  used  or held  in  subsidiaries  or
     affiliates of the Company as of September 18, 2003.

2.   Continued  Employment  for  Limited  Time;  Additional  Services:  You will
     continue  as an employee  of the  Company to provide  consultative  advice,
     support,  transition  assistance  and other  services  to the Company for a
     period  of sixty  (60)  days  following  your  resignation,  namely,  until
     November 17, 2003. Such employment may continue  thereafter (but in no case
     beyond  December  31,  2003) if  requested  at the sole  discretion  of the
     President  of  Allmerica  Financial  Corporation,   namely,   Frederick  H.
     Eppinger, and if agreeable by you. Your services pursuant to this Agreement
     shall  be as an  employee  and not as an  officer  of  Allmerica  Financial
     Corporation or any of its  subsidiaries or affiliates.  The actual services
     to be  provided by you shall be  determined  by Mr.  Eppinger  from time to
     time. During the period of time for which you are providing  services,  you
     shall be paid at your current  salary rate and be entitled to your existing
     fringe benefits.

3.   Severance  Compensation:  Pursuant to the terms of an Employment  Agreement
     dated  November  1,  2002  between  the  Company  and you (the  "Employment
     Agreement"),  you are  entitled  to receive a  severance  benefit  equal to
     $600,000.  This  benefit will be paid to you upon the  termination  of your
     employment  pursuant to this Agreement.  This



     Agreement  shall  supercede  theEmployment   Agreement,   which  is  hereby
     terminated and you shall have no further rights thereunder.

4.   2003 Incentive  Compensation:  You will receive a 2003 Short Term Incentive
     Compensation award in the amount of $227,800, payable to you as of December
     31,  2003,  conditioned  on  applying  such award to the loan as  described
     below.  The  Company,  as of the date the award is  payable  to you,  shall
     credit the net amount  (the amount  remaining  after  deducting  applicable
     Federal and State  income and other taxes) to any amounts then unpaid under
     the Credit Line Promissory Note dated February 5, 2001 from AMGRO,  Inc. to
     you and your spouse,  Mary Frances  Restrepo  (the "Credit Line  Promissory
     Note"),  with any amount in excess of the outstanding  balance and interest
     accrued  thereunder to be payable to you. You acknowledge that AMGRO,  Inc.
     may apply this payment against  principal or interest,  or a combination of
     both as it, in its sole discretion, determines.

5.   COBRA Benefit: Once your employment  relationship has ended (i.e. when your
     services are no longer  required  pursuant to the  provisions  of Section 2
     above) the Company  agrees to pay on your behalf the  premiums due pursuant
     to the terms of your COBRA  election for your  existing  medical and dental
     benefits.  This benefit will continue until the earlier of your  commencing
     new employment and being eligible to receive  medical and dental  benefits,
     your being eligible to obtain fringe benefits on a group basis from another
     source or eighteen (18) months from the date your COBRA benefits  commence.
     For purposes of this  section it shall be  construed  that you are eligible
     for  medical  and  dental  benefits  if,  as  a  partner,  joint  venturer,
     independent  contractor  or any other  status,  you are eligible to receive
     medical and dental benefits at a group rate.

6.   Vacation Entitlement:  The Company will also pay you for any accrued unused
     vacation  time that you are entitled to as of the date your  employment  is
     terminated.  Signing this  Agreement is not required for you to receive the
     payments described in this paragraph.

7.   Outplacement:  The Company will make available to you so-called  "Executive
     Outplacement  Assistance"  for a period of twelve  (12)  months,  beginning
     immediately, at a mutually acceptable outplacement firm.

8.   Stock Plan: All of your unvested  options,  unvested  restricted  stock and
     unexercised  vested  options  under  the  Allmerica  Financial  Corporation
     Long-Term Stock Incentive Plan (the "Stock Plan") will be cancelled and you
     shall have no rights with respect thereto and such options and shares shall
     revert to the Stock Plan upon the  termination of your  employment.  To the
     extent anything herein is inconsistent  with the Stock Plan, the provisions
     of the Stock Plan shall govern.

9.   General Cooperation:  After termination of your employment, you agree to be
     generally  available to respond to questions and/or inquiries,  and provide
     other  information  concerning  matters  that were within the ambit of your
     responsibility  during  your  employment  with the  Company  and  generally
     cooperate  with  respect  to  matters  relating  to  the  Company.   It  is
     anticipated  that most matters can be addressed  through phone calls



     and/or emails.  Certain matters,  however, may require meetings at mutually
     acceptable times and places.

10.  Non-Solicitation:  You  agree  for a  period  of two  years  following  the
     termination of your  employment with the Company that you will not directly
     or  indirectly  solicit  any client or  policyholder  of the Company or its
     affiliates  or  assist  any other  person  or  entity to do so or  solicit,
     recruit or hire or assist or encourage a third party to solicit, recruit or
     hire the services of any current  employee,  agent or broker of the Company
     or its affiliates.

11.  Proprietary  Information:  You  acknowledge  that  your  position  with the
     Company has been one of high trust and confidence and that in the course of
     your  services  to the  Company  you have had  access to and  contact  with
     Proprietary  Information.  You agree not to disclose to others,  or use for
     your benefit or the benefit of others,  any  Proprietary  Information.  For
     purposes  of  this   Agreement,   'Proprietary   Information"   shall  mean

     information,  budgetary/price/cost  information,  agent, broker, reinsurer,
     employee or insured  lists or  confidential  information  involving  policy
     forms, litigation or claim matters, including potential claim matters.

12.  Remedies:  You acknowledge that any breach of the provisions of Sections 10
     and 11 of this Agreement shall result in serious and irreparable  injury to
     the Company  and/or its  subsidiaries  or affiliates  for which the Company
     cannot be  adequately  compensated  by monetary  damage  alone.  You agree,
     therefore,  that in addition  to any other  remedy  which it may have,  the
     Company shall be entitled to specific  performance of Sections 10 and 11 of
     this Agreement by you and to seek both  temporary and permanent  injunctive
