                  commencement of such period, for dollar deposits of a
                  comparable amount and period from other banks in the London
                  interbank market (as reasonably determined by Lender), or if
                  Lender shall cease to make such bids, the equivalent bid rate,
                  as reasonably determined by Lender, derived from display page

the Facility Documents as to the application of the proceeds of the loans made
pursuant thereto.

          We call your attention to the fact that each of the Facility Documents
provides that it is to be governed by and construed in accordance with the laws
of the State of New York, and we understand that you are relying on the advice
of your own counsel with respect to all matters involving New York law.  For
purposes of rendering the opinions expressed in paragraph 3 below, we have
assumed that each Facility Document is to be governed by and construed in
accordance with the internal laws of The Commonwealth of Massachusetts.

          The opinions expressed below are limited to matters governed by the
internal laws of The Commonwealth of Massachusetts, the Federal laws of the
United States of America and the Delaware General Corporation Law.  The
following opinions do not purport to cover matters relating to Regulations T, U
or X of the Board of Governors of the Federal Reserve System.

          In connection with this opinion, we have examined executed copies of
the Facility Documents and such other documents, records, agreements and
certificates as we have deemed appropriate.  We have also reviewed such matters
of law as we have considered relevant for the purpose of this opinion.

          Based upon the foregoing, we are of the opinion that:

          1.  Each Borrower is a corporation duly incorporated, validly existing
and in good standing under the laws of the jurisdiction of its incorporation,
has the corporate power and authority to borrow under the Facility Documents and
to execute and deliver and to perform is obligations under, the Facility
Documents.

6

 
          2.  The execution, delivery and performance by each Borrower of the
Facility Documents have been duly authorized by all necessary corporate action
and do not and will not (a) contravene such Borrower's charter or by-laws,  
(b) violate any applicable law, rule or regulation of the United States of
America, The Commonwealth of Massachusetts or the Delaware General Corporation
law, or (c) result in a breach of, constitute a default under, require any
consent under, or result in the acceleration or required prepayment of any
indebtedness pursuant to the terms of, any agreement or instrument to which such
Borrower or any of its Subsidiaries is a party, or by which any of them is bound
or to which any of them is subject, and which has been or is required to be
filed with the Securities and Exchange Commission, or result in the creation or
imposition of any Lien upon any Property of such Borrower pursuant to, the terms
of any such agreement or instrument.

          3.  Each Facility Document is, or when delivered under the Letter
Agreement will be, a legal, valid and binding obligation of each Borrower,
enforceable against such Borrower in accordance with its terms.

          Our opinions that each of the Facility Documents being delivered to
you today constitute the legal, valid and binding obligation of the Borrowers,
enforceable against them in accordance with its terms, are subject to (a)
bankruptcy, insolvency, reorganization, moratorium and other laws of general
application affecting the rights and remedies of creditors and secured parties
and (b) general principles of equity, regardless of whether enforcement is
sought in proceedings in equity or at law.

          We express no opinion with respect to the applicability of Section 548
of the Bankruptcy Code or any other fraudulent conveyance provision.  In
particular, we express no opinion as to whether a subsidiary may guarantee or
otherwise become liable for, or pledge its assets to secure, indebtedness
incurred by its parent or another subsidiary of its parent, except to the extent
such subsidiary may be determined to have received a benefit from the incurrence
of such indebtedness by its parent or such other subsidiary, or as to whether
such benefit may be measured other than by the extent to which the proceeds of
the indebtedness incurred by the parent or such other subsidiary are directly or
indirectly made available to such subsidiary for its corporate purposes.  We
call your attention to the fact that certain cases have held that an obligation
of a corporation incurred to purchase a corporation's stock may under certain
circumstances become subordinate to the claims of general creditors upon the
bankruptcy or insolvency of the corporation.

          The foregoing opinions are subject to the following comments and
qualifications:

          (A)  The enforceability of the Facility Documents may be limited by
laws rendering unenforceable indemnification contrary to Federal or state
securities laws and the public policy underlying such laws.

          (B)  The enforceability of provisions in the Facility Documents to the
effect that terms may not be waived or modified except in writing may be limited
under certain circumstances

          (C) We express no opinion as to (i) the effect of the laws of any
jurisdiction in which the Lender is located that limit the interest, fees or
other charges the Lender may impose and (ii) the second sentence of the section
of the Letter Agreement captioned "Governing Law; Jurisdiction" and the first
sentence of Section 5(e) of the Note, insofar as such sentences relate to the
subject matter jurisdiction of the United States District Court for the Southern
District of New York to adjudicate any controversy related to the Facility
Documents.

7

 
          The foregoing opinion is solely for your benefit and may not be relied
on by any other Person.

                                                   Very truly yours,

trustee or agent on behalf of such holder or holders) to cause, such
Indebtedness to become due, or to be prepaid in full (whether by redemption,
purchase, offer to purchase or otherwise), prior to its stated maturity or to
have the interest rate thereon reset to a level so that securities evidencing
such Indebtedness trade at a level specified in relation to the par value
thereof; (f) Allmerica shall fail to pay when due (after giving effect to any
applicable grace periods) of any amount aggregating $10,000,000 or more on any
of its Rate Hedging Obligations (as defined in the Existing Credit Agreement) or

(with the giving of notice or the lapse of time or both) to permit, termination
or liquidation payment or payments aggregating $10,000,000 or more to become
due; (g) Citizens Acquisition or Allmerica or any of its Insurance Subsidiaries

liability for the obligations under this Note in consideration of the financial
accommodation provided by the Bank under the Letter Agreement and agrees that if
and to the extent that a Borrower shall fail to make any payment due hereunder
as and when due in accordance with the terms hereof, then the other Borrower
will make such payment.  The liability of each Borrower hereunder is absolute

thereby which might constitute a defense available to, or discharge of, a

Agreement.

         (d)  This Note shall be binding on the Borrowers and their successors
and assigns and shall inure to the benefit of the Bank and its successors and
assigns, except that no Borrower may delegate any obligations hereunder without
the prior written consent of the Bank.  This Note may not be assigned by the
Bank except with the prior written consent of the Borrowers, which consent shall
not be unreasonably withheld.

  (e)  Each Borrower consents to the nonexclusive jurisdiction and venue of the
state and federal courts located in the City of New York.  Service of process by
the Bank in connection with any dispute shall be binding on each Borrower if
sent to such Borrower by registered mail at the address specified below.  EACH
OF THE BANK AND EACH BORROWER HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY
LAW, ANY RIGHT IT MAY HAVE TO JURY TRIAL IN ANY LEGAL PROCEEDING DIRECTLY OR
INDIRECTLY ARISING OUT OF OR RELATING TO THIS NOTE OR TRANSACTIONS CONTEMPLATED
HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY).

         (f)  This Note shall be governed by and interpreted and construed in
accordance with the laws of the State of New York, provided that the foregoing
                                                   --------

received or receivable by the Bank hereunder is reduced, or the Bank is required

to compensate it for such payment. Without limiting the effect of the preceding
sentence, such compensation shall include an amount equal to the excess, if any,
of (i) the amount of interest which would have accrued on the principal amount
of such Loan had Borrowers not so paid, for the period from the date of such
payment to the last day of the current interest period therefor over (ii) the
amount of interest which would accrue on such principal amount for such period

of such period, for dollar deposits of a comparable amount and period from other
banks in the London interbank market (as reasonably determined by Lender), or if
Lender shall cease to make such bids, the equivalent bid rate, as reasonably
determined by Lender, derived from display page 3750 (British Bankers
Association - LIBOR) of the Dow Jones Markets (Telerate) Screen (or any
successor or substitute therefor).

trustee or agent on behalf of such holder or holders) to cause, such
Indebtedness to become due, or to be prepaid in full (whether by redemption,

have the interest rate thereon reset to a level so that securities evidencing
such Indebtedness trade at a level specified in relation to the par value
thereof; (f) Allmerica shall fail to pay when due (after giving effect to any
applicable grace periods) of any amount aggregating $10,000,000 or more on any
