                  SECTION 1. Representations and Warranties.
                             ------------------------------

                  (a) Each of the Trust and the Company represents and warrants
to each Initial Purchaser as of the date hereof and as of the Closing Time
referred to in Section 2(b) hereof, and agrees with each Initial Purchaser as
follows:

                  (i)   The Offerors have not, directly or indirectly, solicited
         any offer to buy or offered to sell, and will not, directly or
         indirectly, solicit any offer to buy or offer to sell, in the United
         States or to any United States citizen or resident, any security which
         is or would be integrated with the sale of the Series A Capital
         Securities in a manner that would require the Series A Capital
         Securities to be registered under the 1933 Act.

                  (ii)  Each of the Preliminary Offering Memorandum and the
         Final Offering Memorandum as of their respective dates does not, and in
         the case of the Final Offering Memorandum as of the Closing Time will
         not, include an untrue statement of a material fact or omit to state a
         material fact necessary in order to make the statements therein, in the
         light of the circumstances under which they were made, not misleading;
         provided that this representation, warranty and agreement shall not
         apply to statements or omissions made in reliance upon and in
         conformity with information furnished to the Offerors by or on behalf
         of any Initial Purchaser through Merrill Lynch expressly for use in the
         Offering Memorandums.

                  (iii) Each of the Capital Securities, the Capital Securities
         Guarantees and the Junior Subordinated Debentures satisfy the
         eligibility requirements of Rule 144A(d)(3) under the 1933 Act.

 
                                       5

                  (iv)  The documents incorporated or deemed to be incorporated
         by reference in the Offering Memorandums at the time they were or
         hereafter are filed with the Commission complied and will comply in all
         material respects with the requirements of the 1934 Act and the rules
         and regulations of the Commission thereunder (the "1934 Act
         Regulations"), and, when read together with the other information in
         the Offering Memorandums, at the date of each respective Offering
         Memorandum and, in the case of the Final Offering Memorandum, at the
         Closing Time, do not and will not include an untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein, in the light of
         the circumstances under which they were made, not misleading.

                  (v)   Price Waterhouse LLP, who are reporting upon the audited
         consolidated financial statements and supporting schedules 1 through 6
         of the Company's Annual Report on Form 10-K for the fiscal year ended
         December 31, 1995 included or incorporated by reference in the Offering
         Memorandums, are independent public accountants as required by the 1933
         Act and the 1933 Act Regulations.

                  (vi)  The consolidated financial statements, together with the
         related schedules and notes thereto included in the Offering
         Memorandums, present fairly in all material respects the financial
         position of the Company and its subsidiaries at the dates indicated and
         the consolidated statement of income, shareholders' equity and cash
         flows of the Company and its subsidiaries for the periods specified;
         said consolidated financial statements have been prepared in conformity
         with generally accepted accounting principles ("GAAP") applied on a
         consistent basis throughout the periods involved except as noted
         therein. The supporting schedules, if any, included in the Offering
         Memorandums present fairly the information required to be stated
         therein. The selected financial data included in the Offering
         Memorandums present fairly the information shown therein and have been
         compiled on a basis consistent with that of the consolidated audited
         financial statements included in the Offering Memorandums except as
         noted therein. The pro forma financial statements and other pro forma
         financial information included in the Offering Memorandums present
         fairly the information shown therein, have been prepared in accordance
         with the Commission's rules and guidelines with respect to pro forma
         financial statements, have been properly compiled on the pro forma
         bases described therein, and, in the opinion of the Company, the
         assumptions used in the preparation thereof are reasonable and the
         adjustments used therein are appropriate to give effect to the proposed
         transactions referred to therein.

                  (vii) The statutory consolidated financial statements of the
         Company and its subsidiaries, from which certain ratios and other
         statistical data contained in the Offering Memorandums have been
         derived, have for each relevant period been 

 
                                       6

         prepared in accordance with accounting practices prescribed or
         permitted by the National Association of Insurance Commissioners and
         the insurance division of the Commonwealth of Massachusetts, and such
         accounting practices have been applied on a consistent basis throughout
         the periods involved, except as disclosed therein.

                  (viii) Since the respective dates as of which information is
         given in the Offering Memorandum, except as otherwise described or
         stated therein, (A) there has been no material adverse change in the
         condition, financial or otherwise, or in the earnings, business affairs
         or business prospects of the Trust or the Company and its subsidiaries
         considered as one enterprise, whether or not arising in the ordinary
         course of business, (B) there have been no transactions entered into by
         the Trust or the Company or any of its subsidiaries, other than those
         in the ordinary course of business, which are material with respect to
         the Trust or the Company and its subsidiaries considered as one
         enterprise, and (C) except for regular quarterly dividends, there has
         been no dividend of any kind declared, paid or made by the Company on
         any class of its capital stock.

                  (ix)   The Company is a corporation organized, validly
         existing and in good standing under the laws of the State of Delaware,
         with corporate power and authority under such laws to own, lease and

         duly qualified to transact business as a foreign corporation and is in
         good standing in each other jurisdiction in which it owns or leases
         property of a nature, or transacts business of a type, that would make
         such qualification necessary, except to the extent that the failure to
         so qualify or be in good standing would not have a material adverse
         effect on the Company and its subsidiaries, considered as one
         enterprise.

         jurisdiction of its incorporation with corporate power and authority
         under such laws to own, lease and operate its properties and conduct
         its business; and each Subsidiary is duly qualified to transact
         business as a foreign corporation and is in good standing in each other
         jurisdiction in which it owns or leases property of a nature, or
         transacts business of a type, that would make such qualification
         necessary, except to the extent that the failure to so qualify or be in
         good standing would not have a material adverse effect on the Company
         and its subsidiaries, considered as one enterprise. All of the
         outstanding shares of capital stock of each Subsidiary have been duly
         authorized and validly issued and are fully paid and non-assessable.
         Except for Allmerica P&C and Citizens, which are owned 40.5% and 17.5%,

         perform its obligations under such of the Operative Documents to which
         it is a party and the Series A Capital Securities; the Trust is duly
         qualified to transact business as a foreign corporation and is in good
         standing in each jurisdiction in which such qualification is necessary,
         except to the extent that the failure to so qualify or be in good
         standing would not have a material adverse effect on the Trust; the
         Trust is not a party to or otherwise bound by any agreement other than
         those described in the Offering Memorandum; the Trust is and will under

         pursuant to generally accepted accounting principles.

                  (xiv)  The Declaration has been duly authorized by the Company

         the due authorization, execution and delivery of the Declaration by the
         Delaware Trustee and the Property Trustee (as defined in the
         Declaration)) will, at the Closing Time, be a valid and binding

         conveyance, moratorium or similar laws affecting creditors' rights
         generally and except as enforcement thereof is subject to general

         Memorandums.

         undivided beneficial interests in the assets of the Trust, will be
         entitled to the benefits of the Declaration and will conform in all
         material respects to the description thereof in the Offering
         Memorandums; the issuance of the Series A Capital Securities is not

         conveyance, moratorium or similar laws affecting creditors' rights
         generally and except as enforcement thereof is subject to general

         other subsidiaries is or, after giving effect to the consummation of
         the transactions contemplated herein, will 

 
                                       11



         be, and neither the Company nor the Trust nor any of the Company's
         other subsidiaries is directly or indirectly controlled by, or acting
         on behalf of any person which is, an "investment company" within the
         meaning of the Investment Company Act of 1940, as amended.

                  (xxiv) None of the Company, any Subsidiary or the Trust is in
         default in the performance or observance of any obligation, agreement,
         covenant or condition contained in any contract, indenture, mortgage,
         loan agreement, note, lease or other agreement or instrument to which
         it is a party or by which it may be bound or to which any of its
         properties may be subject, except for such defaults that would not have
         a material adverse effect on the condition (financial or otherwise),
         earnings, business affairs or business prospects of the Company and its
         subsidiaries, considered as one enterprise. The execution and delivery

         or Trust Certificate, and do not and will not conflict with, or result
         in a breach of any of the terms or provisions of, or constitute a
         default under, or result in the creation or imposition of any lien,
         charge or encumbrance upon any property or assets of the Company, the
         Trust or any Subsidiary under (A) any contract, indenture, mortgage,
         loan agreement, note, lease or other agreement or instrument to which
         the Company, the Trust or any Subsidiary is a party or by which it may
         be bound or to which any of its properties may be subject (except for
         such conflicts, breaches or defaults or liens, charges or encumbrances
         that would not have a material adverse effect on the condition
         (financial or otherwise), earnings, business affairs or business
         prospects of the Company and its subsidiaries, considered as one
         enterprise, or of the Trust) or (B) any existing applicable law, rule,
         regulation, judgment, order or decree of any government, governmental
         instrumentality or court, domestic or foreign, having jurisdiction over
         the Company, the Trust or any Subsidiary or any of their respective
         properties.

                  (xxv)  Neither the issuance and sale of the Capital Securities
         by the Trust to the Initial Purchasers or the issuance and sale of the
         Common Securities by the Trust to the Company, the extension of the
         Series A Guarantee by the Company, the issuance and sale of the
         Subordinated Debentures by the Company to the Trust, the execution,
         delivery or performance of this Agreement, the Declaration, the
         Indenture and the Series A Guarantee by the Offerors, nor the
         consummation by the Offerors with their respective obligations
         hereunder and thereunder requires any consent, approval, authorization
         or other order of or registration or filing with, any court, regulatory
         body (including any insurance regulatory body), administrative agency
         or other governmental 

 
                                       12


         body, agency or official (except such as may be required under the 1933
         Act, the 1934 Act and the Trust Indenture Act and compliance with the
         securities, Blue Sky laws and state insurance laws of various
         jurisdictions), except where the failure to obtain such consent,
         approval, authorization or other order or make such registration or
         filing would not have a material adverse effect on the condition
         (financial or otherwise), earnings, business affairs and business
         prospects of the Company and its subsidiaries considered as one
         enterprise.

                  (xxvi) To the best knowledge of the company, no labor problem
         exists with its employees or with employees of the Subsidiaries or the
         Trust, or is imminent that could adversely affect the Trust, or the
         Company and its subsidiaries, considered as one enterprise.

                  (xxvii) Except as disclosed in the Offering Memorandum, there
         is no action, suit or proceeding before or by any government,
         governmental instrumentality or court, domestic or foreign, now pending
         or, to the knowledge of the Company, threatened against or affecting
         the Trust, the Company, or any of its Subsidiaries that is required to
         be disclosed in the Offering Memorandums or that could have a material
         adverse change in the condition (financial or otherwise), earnings,
         business affairs or business prospects of the Trust, and the Company
         and its subsidiaries, considered as one enterprise, or that could
         materially and adversely affect the properties or assets thereof or the
         consummation of any Operative Documents or the performance by the
         Company of its obligations hereunder and thereunder; the aggregate of
         all pending legal or governmental proceedings to which the Trust, or
         the Company or any Subsidiary is a party or which affect any of their
         respective properties or assets, including ordinary routine litigation
         incidental to the business of the Trust, or the Company or any
         Subsidiary, would not reasonably be expected to have a material adverse
         effect on the condition (financial or otherwise), earnings, business
         affairs or business prospects of the Trust, or the Company and its
         subsidiaries, considered as one enterprise.

                  (xxviii) The Trust, the Company and each of the Subsidiaries
         each has good and marketable title to all properties and assets
         described in the Offering Memorandums as owned by it, free and clear of
         all liens, charges, encumbrances or restrictions, except such as (A)
         are described in the Offering Memorandums or (B) are not materially
         significant in relation to the business of the Trust, the Company and
         its subsidiaries, considered as one enterprise; all of the leases and
         subleases material to the business of the Trust, the Company and its
         subsidiaries, considered as one enterprise, and under which the Trust,
         the Company or any Subsidiary holds properties, are described in the
         Offering Memorandums, are in full force and effect; and neither the
         Trust, the Company nor any Subsidiary has any notice of any material
         claim of any sort that has been asserted by anyone adverse to the
         rights of the Trust, the Company or any 

 
                                       13


         Subsidiary under any of the leases or subleases mentioned above, or
         affecting or questioning the rights of such corporation to the
         continued possession of the leased or subleased premises under any such
         lease or sublease.

                  (xxix) The Trust, the Company and its Subsidiaries each owns,
         possesses or has obtained all material governmental licenses, permits,
         certificates, consents, orders, approvals and other authorizations
         necessary to own or lease, as the case may be, and to operate its
         properties and to carry on its business as presently conducted, and
         neither the Trust, the Company nor any of its Subsidiaries has received
         any notice of proceedings relating to revocation or modification of any
         such licenses, permits, certificates, consents, orders, approvals or
         authorization.

                  (xxx) Each of the Subsidiaries which is engaged in the
         insurance business, (the "Insurance Subsidiaries"), is duly licensed or
         authorized to conduct its insurance business under the insurance laws
         of each jurisdiction in which it conducts such business so as to
         require such licensing or authorization, except where the failure to be
         so licensed or authorized would not, individually or in the aggregate,
         have a material adverse effect on the condition (financial or
         otherwise), earnings, business affairs or business prospects of the
         Trust, the Company and its subsidiaries, considered as one enterprise;
         all such licenses or authorizations are in full force and effect and
         neither the Trust, the Company nor any Insurance Subsidiary has
         received any notice of any event, inquiry, investigation or proceeding
         that would reasonably be expected to result in the suspension,
         revocation or limitation of any such licenses or authorizations or
         otherwise impose any limitation on the conduct of the business of the
         Trust, the Company or any Insurance Subsidiary, except any such
         suspension, revocation or limitation which would not, individually or
         in the aggregate, have a material adverse effect on the condition
         (financial or otherwise), earnings, business affairs or business
         prospects of the Trust, the Company and its subsidiaries, considered as
         one enterprise, and to the best of the Trust's, the Company's and the
         Insurance Subsidiaries' knowledge, there is no sustainable basis for
         any such suspension, revocation or limitation; each of the Insurance
         Subsidiaries is in compliance with, and conducts its businesses in
         conformity with, all applicable insurance laws and regulations, except
         where the failure to so comply or conform would not have a material
         adverse effect on the condition (financial or otherwise), earnings,
         business affairs or business prospects of the Company and its
         subsidiaries, considered as one enterprise; and the Company has
         disclosed to you all pending significant examinations, and all
         significant examinations which have been completed and filed since
         October 1995, by any governmental authority having jurisdiction to
         regulate the insurance operations of any Insurance Subsidiary.

                  (xxxi) The Trust, the Company and the Subsidiaries each owns
         or possesses, or can acquire on reasonable terms, adequate patents,
         patent licenses, trademarks, 

 
                                       14


         service marks and trade names necessary to carry on its business as
         presently conducted, and neither the Trust, the Company nor any
         Subsidiary has received any notice of infringement of or conflict with
         asserted rights of others with respect to any patents, patent licenses,
         trademarks, service marks or trade names that in the aggregate, if the
         subject of an unfavorable decision, ruling or finding, could materially
         adversely affect the condition (financial or otherwise), earnings,
         business affairs or business prospects of the Trust, the Company and
         its subsidiaries, considered as one enterprise.

                  (xxxii) To the best of the Company's knowledge, except as
         disclosed in the Offering Memorandums, no change in any insurance laws
         or regulations of Massachusetts, Michigan, New Hampshire or Delaware is
         pending or has been introduced which could reasonably be expected to be
         adopted and, if adopted, could reasonably be expected to have,
         individually or in the aggregate with all such changes, a material
         adverse effect upon the condition (financial or otherwise), earnings,
         business affairs or business prospects of the Company and its
         subsidiaries, considered as one enterprise.

 
                                       15



         SECTION 2.  Sale and Delivery to Initial Purchasers; Closing.
                     ------------------------------------------------

              (a)     On the basis of the representations and warranties herein
contained and subject to the terms and conditions herein set forth, the Trust
agrees to sell to each Initial Purchaser and each Initial Purchaser agrees to
purchase from the Trust, at a price of $1,000 per Series A Capital Security, the
number of Series A Capital Securities set forth in Schedule A opposite the name
of such Initial Purchaser, plus any additional Series A Capital Securities which
such Initial Purchaser may become obligated to purchase pursuant to the
provisions of Section 11 hereof.

              (b)     Deliveries of certificates for the respective accounts of
the Initial Purchasers for the Series A Capital Securities shall be made at the
office of Merrill Lynch in New York, and payment of the purchase price for the
Series A Capital Securities shall be made by Merrill Lynch on behalf of the
several Initial Purchasers, to the Trust by wire transfer of immediately
available funds contemporaneous with closing at such place as shall be agreed
upon by Merrill Lynch and the Offerors, at 10:00 A.M. on February 3, 1997
(unless postponed in accordance with the provisions of Section 11), or such
other time not later than ten business days after such date as shall be agreed
upon by Merrill Lynch and the Offerors (such time and date of payment and
delivery being herein called the "Closing Time").

         Certificates for the Series A Capital Securities shall be in such
denominations and registered in such names as the Initial Purchasers may request
in writing at least one business day before the Closing Time. It is understood
that each Initial Purchaser has authorized Merrill Lynch, for its account, to
accept delivery of, receipt for, and make payment of the purchase price for, the
Series A Capital Securities which it has agreed to purchase. Merrill Lynch,
individually and not as representative of the Initial Purchasers, may (but shall
not be obligated to) make payment of the purchase price for the Series A Capital
Securities, to be purchased by any Initial Purchaser whose funds have not been
received by the Closing Time, but such payment shall not relieve such Initial
Purchaser from its obligations hereunder. The certificates representing the
Series A Capital Securities which are not resold to institutional "accredited
investors" shall be registered in the name of Cede & Co. pursuant to the DTC
Agreement and shall be made available for examination and packaging by the
Initial Purchasers in The City of New York not later than 10:00 A.M. on the last
business day prior to the Closing Time.

         (c)  As compensation to the Initial Purchasers for their commitment
hereunder and in view of the fact that the proceeds of the sale of the Series A
Capital Securities will be used to purchase Series A Junior Subordinated
Debentures of the Company, the Company hereby agrees to pay at the Closing Time
to Merrill Lynch in immediately available funds, for the accounts of the several
Initial Purchasers, $10 per Series A Capital Security to be delivered by the
Trust hereunder at the Closing Time.

 
                                       16


         (d)  Each Initial Purchaser represents and warrants to, and agrees
with, the Company that it is a Qualified Institutional Buyer (as defined in
Section 6(a)(i)) and an Institutional Accredited Investor (as defined in Section
6(a)(i)).

         SECTION 3.  Covenants of the Offerors.
                     -------------------------

         The Offerors covenant with each Initial Purchaser as follows:

         (a)  The Offerors, as promptly as possible, will furnish to each
Initial Purchaser, without charge, such number of copies of the Final Offering
Memorandum and any amendments and supplements thereto and documents incorporated
by reference therein as such Initial Purchaser may reasonably request.

         (b)  The Offerors will immediately notify each Initial Purchaser, and
confirm such notice in writing, of (x) any filing made by the Offerors of
information relating to the offering of the Series A Capital Securities to the
Initial Purchasers with any securities exchange or any other regulatory body in
the United States or any other jurisdiction, and (y) prior to the completion of
the placement of the Series A Capital Securities by the Initial Purchasers as
evidenced by a notice in writing from the Initial Purchasers to the Offerors,
any material changes in or affecting the earnings, business affairs or business
prospects of the Trust, or the Company and its subsidiaries considered as one
enterprise, which (i) make any statement in the Offering Memorandums false or
misleading or (ii) are not disclosed in the Offering Memorandums. In such event
or if during such time any event shall occur as a result of which it is
necessary, in the reasonable opinion of the Company, its counsel or counsel for
the Initial Purchasers, to amend or supplement Final Offering Memorandum in
order that the Final Offering Memorandum not include any untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements therein not misleading in the light of the circumstances then
existing, the Company will forthwith amend or supplement the Final Offering
Memorandum by preparing and furnishing to each Initial Purchaser an amendment or
amendments of, or a supplement or supplements to, the Final Offering Memorandum
(in form and substance satisfactory in the reasonable opinion of counsel for the
Initial Purchasers) so that, as so amended or supplemented, the Final Offering
Memorandum will not include an untrue statement of a material fact or omit to
state a material fact necessary in order to make the statements therein, in the
light of the circumstances existing at the time it is delivered to a Subsequent
Purchaser, not misleading.

         (c)  The Offerors will advise each Initial Purchaser promptly
of any proposal to amend or supplement the Offering Memorandums and will not
effect such amendment or supplement without the consent of the Initial

 
                                       17

Purchasers, which consent shall not be unreasonably withheld. Neither the
consent of the Initial Purchasers, nor the Initial Purchasers' delivery of any
such amendment or supplement, shall constitute a waiver of any of the conditions
set forth in Section 5 hereof.

         (d)  The Offerors shall take all reasonable action necessary to enable
Standard & Poor's Ratings Services, a division of McGraw Hill, Inc. ("S&P"), and
Moody's Investors Service, Inc. ("Moody's") to provide their respective credit
ratings of the Capital Securities.

         (e)  The Offerors will cooperate with the Initial Purchaser and use
reasonable efforts to permit the Series A Capital Securities to be eligible for
clearance and settlement through the facilities of DTC.

         (f)  The Trust will use the net proceeds received by it from the sale
of the Series A Capital Securities; and the Company will use the proceeds
received by it from the sale of the Series A Junior Subordinated Debentures, in
the manners specified in the Offering Memorandums under "Use of Proceeds".

         (g)  Prior to 30 days after the date hereof, neither the Trust nor the
Company will, without the prior written consent of Merrill Lynch, directly or
indirectly, issue, sell, offer or agree to sell, grant any option for the sale
of, or otherwise dispose of, Capital Securities, any security convertible into
exchangeable or exercisable for Capital Securities or the Junior Subordinated
Debentures or any debt securities substantially similar (including provisions
with respect to the deferral of interest) to the Junior Subordinated Debentures
or any equity security substantially similar to the Capital Securities (except
for the Securities issued pursuant to this Agreement); provided, however, that
the foregoing restrictions shall not apply to any disposal of the Junior
Subordinated Debentures following any liquidation of the Trust.

         SECTION 4.  Payment of Expenses.
                     -------------------

         (a)  Expenses. The Company will pay all expenses incident to the
performance of its obligations under this Agreement, including (i) the
preparation, printing and any filing of the Offering Memorandums (including
financial statements and any schedules or exhibits and any document incorporated
therein by reference) and of each amendment or supplement thereto, (ii) the
preparation, printing and delivery to the Initial Purchasers of this Agreement,
the Operative Documents and such other documents as may be required in
connection with the offering, purchase, sale and delivery of the Securities,
(iii) the preparation, issuance and delivery of the certificates for the Series
A Capital Securities, the Series A Capital Securities Guarantee and the Series A
Junior Subordinated Debentures to the Initial Purchasers, (iv) the fees and
disbursements of the Company's counsel, accountants and other advisors, (v)
rating agency fees, and (vi) the fees and expenses of any trustee appointed

 
                                       18

under any of the Operative Documents, including the fees and disbursements of
counsel for such trustees in connection with the Operative Documents.

         (b)  Termination of Agreement. If this Agreement is terminated by the
Initial Purchasers in accordance with the provisions of Section 5 or Section
10(a)(i) hereof, the Company shall reimburse the Initial Purchasers for all of
their out-of-pocket expenses, including the reasonable fees and disbursements of
Shearman & Sterling, counsel for the Initial Purchasers.

         SECTION 5.  Conditions of Initial Purchasers' Obligations.
                     ---------------------------------------------

         The obligations of the Initial Purchasers hereunder are subject to the
accuracy of the representations and warranties of the Offerors contained in
Section 1 hereof or in certificates of any Trustee of the Trust, officer of the
Company or any of its subsidiaries delivered pursuant to the provisions hereof,
to the performance by the Offerors of their obligations hereunder, and to the
following further conditions:

         (a)  Opinion of Outside Counsel for Offerors. At the Closing Time, the
Initial Purchasers shall have received the favorable opinion, dated as of the
Closing Time, of Ropes & Gray, counsel for the Company, in form and substance
reasonably satisfactory to counsel for the Initial Purchasers. Such counsel may
also state that, insofar as such opinion involves factual matters, they have
relied, to the extent they deem proper, upon certificates of Trustees of the
Trust, officers of the company and its subsidiaries and certificates of public
officials; provided that such certificates have been delivered to the Initial
           --------
Purchasers.

         (b)  Opinion of Special Delaware Counsel for Offerors. At the Closing
Time, the Initial Purchasers shall have received the favorable opinion, dated as
of the Closing Time, of Richards, Layton & Finger, special Delaware counsel to
the Offerors, in form and substance reasonably satisfactory to counsel for the
Initial Purchasers. Such counsel may also state that, insofar as such opinion
involves factual matters, they have relied, to the extent they deem proper, upon
certificates of Trustees of the Trust, officers of the company and its
subsidiaries and certificates of public officials; provided that such
                                                   --------  
certificates have been delivered to the Initial Purchasers.

         (c)  Opinion of Counsel for The Chase Manhattan Bank. At the Closing
Time, the Initial Purchasers shall have received the favorable opinion, dated as
of the Closing Time, of Seward & Kissel, counsel to The Chase Manhattan Bank, as
Property Trustee under the Declaration, as Guarantee Trustee under the Series A
Guarantee Agreement, and as Debenture Trustee under the Indenture in form and
substance reasonably satisfactory to counsel for the Initial Purchasers.

 
                                       19

         (d)  Opinion of Special Tax Counsel for the Offerors. At the Closing
Time, the Initial Purchasers shall have received an opinion, dated as of the
Closing Time, of Latham & Watkins, special tax counsel to the Offerors, that (i)
the Junior Subordinated Debentures will be classified for United States federal
income tax purposes as indebtedness of the Company, (ii) the Trust will be
classified for United States federal income tax purposes as a grantor trust and
not as an association taxable as a corporation and (iii) although the discussion
set forth in the Offering Memorandums under the heading "Certain Federal Income
Tax Consequences" does not purport to discuss all possible United States federal
income tax consequences of the purchase, ownership and disposition of the Series
A Capital Securities, such discussion constitutes, in all material respects, a
fair and accurate summary of the United States federal income tax consequences
of the purchase, ownership and disposition of the Series A Capital Securities
under current law. Such opinion may be conditioned on, among other things, the
initial and continuing accuracy of the facts, financial and other information,
covenants and representations set forth in certificates of officers of the
Company and other documents deemed necessary for such opinion.

         (e)  Opinion of Counsel for Initial Purchasers. At the Closing Time,
the Initial Purchasers shall have received the favorable opinion, dated as of
the Closing Time, of Shearman & Sterling, counsel for the Initial Purchasers,
with respect to the incorporation and legal existence of the Company, the Series
A Capital Securities, the Indenture, the Series A Guarantee Agreement, this
Agreement, the Registration Rights Agreement, the Offering Memorandums and other
related matters as the Initial Purchasers may require. Such counsel may also
state that, insofar as such opinion involves factual matters, they have relied,
to the extent they deem proper, upon certificates of Trustees of the Trust,
officers of the Company and its subsidiaries and certificates of public
officials; provided that such certificates have been delivered to the Initial
Purchasers.

         (f)  Certificates. At the Closing Time there shall not have been, since
the date hereof or since the respective dates as of which information is given
in the Offering Memorandums, any material adverse change, or any development or
event involving a prospective material adverse change, in the condition,
financial or otherwise, or in the earnings, business affairs or business
prospects of the Trust, or the Company and its subsidiaries considered as one
enterprise, whether or not arising in the ordinary course of business, except
that the announcement of or execution of an agreement relating to the terms and
conditions of the Acquisition (as defined in the Offering Memorandums) will not
be considered a material adverse change for purposes of this subsection (f), and
the Initial Purchasers shall have received a certificate of the President or
Chief Executive Officer, and the Treasurer, Chief Financial Officer or Vice-
President of the Company, and a certificate of an Administrative Trustee of the
Trust, dated as of the Closing Time, to the effect that except as disclosed in
the Offering Memorandums, (i) there has been no such material adverse change or
development or event, (ii) the representations and warranties in Section 1
hereof were true  

 
                                       20

and correct with the same force and effect as though expressly made at and as of
the Closing Time, and (iii) the Offerors have complied with all agreements and
satisfied all conditions on their part to be performed or satisfied at or prior
to the Closing Time.

         (g)  Accountant's Comfort Letter. At the time of the execution of this
Agreement, the Initial Purchasers shall have received from Price Waterhouse LLP
a letter dated such date, in form and substance satisfactory to the Initial
Purchasers, containing statements and information of the type ordinarily
included in accountants' "comfort letters" to Initial Purchasers with respect to
the financial statements and certain financial information contained in the
Offering Memorandums.

         (h)  Bring-down Comfort Letter. At the Closing Time, the Initial
Purchasers shall have received from Price Waterhouse LLP a letter, dated as of
the Closing Time, to the effect that they reaffirm the statements made in the
letter furnished pursuant to subsection (h) of this Section, except that the
specified date referred to shall be a date not more than three business days
prior to the Closing Time.

         (i)  Maintenance of Rating. Notwithstanding the satisfaction of any
other condition set forth in this Section 5, at the Closing Time, the Capital
Securities shall be rated at least "a2" by Moody's Investor's Service, Inc. and
BBB+ by Standard & Poor's Ratings Services, and the Trust shall have delivered
to the Initial Purchasers a letter dated the Closing Time, from each such rating
agency, or other evidence satisfactory to the Initial Purchasers, confirming
that the Series A Capital Securities have such ratings; and between the date of
this Agreement and the Closing Time, there shall not have occurred a downgrading
in the rating assigned to the Series A Capital Securities or any of the
Company's other debt securities by any nationally recognized statistical rating
organization, and no such organization shall have publicly announced that it has
under surveillance or review, with possible negative implications, its rating of
any Capital Securities or any of the Company's other debt securities.

         (j)  Additional Documents. At the Closing Time, counsel for the Initial
Purchasers shall have been furnished with the Registration Rights Agreement,
executed by the Company and the Trust, and such documents and opinions as they
may reasonably require for the purpose of enabling them to pass upon the
issuance and sale of the Series A Capital Securities as herein contemplated, or
in order to evidence the accuracy of any of the representations and warranties
of the Offerors, or the fulfillment of any of the conditions, herein contained;
and all proceedings taken by the Offerors in connection with the issuance and
sale of the Series A Capital Securities as herein contemplated shall be
reasonably satisfactory in form and substance to the Initial Purchasers and
counsel for the Initial Purchasers.

 
                                      21

          (k) Termination of Agreement. If any condition specified in this
Section shall not have been fulfilled when and as required to be fulfilled, this
Agreement may be terminated by the Initial Purchasers by notice to the Offerors
at any time at or prior to the Closing Time, and such termination shall be
without liability of any party to any other party except as Provided in Section
4 and except that Sections 7 and 9 shall survive any such termination and remain
in full force and effect.

          SECTION 6. Subsequent Offers and Sales of the Series A Capital
                     ---------------------------------------------------
Securities.
- ----------

          (a) Offer and Sale Procedures.  Each of the Initial Purchasers and the
Offerors hereby establish and agree to observe the following procedures in
connection with the offer and sale of the Series A Securities:

          (i)    Offers and Sales Only to Institutional Accredited Investors,
                 -----------------------------------------------------------
     Qualified Institutional Buyers and Non-U.S. Persons. Offers and sales of
     ---------------------------------------------------
     the Capital Securities will be made only by the Initial Purchasers or
     affiliates thereof qualified to do so in the jurisdictions in which such
     offers or sales are made. Each such offer or sale shall only be made (A) to
     persons whom the offeror or seller reasonably believes to be qualified
     institutional buyers (as defined in Rule 144A under the 1933 Act)
     ("Qualified Institutional Buyers"), or (B) to a limited number of other
     institutional accredited investors (as such term is defined in Rule
     501(a)(1), (2), (3) or (7) of Regulation D) that the Initial Purchasers
     reasonably believe to be and, with respect to sales and deliveries, that
     are accredited investors ("Institutional Accredited Investors"), or (C) 
     non-U-S, persons outside the United States to whom the Initial Purchasers
     reasonably believe offers and sales of the Series A Capital Securities may
     be made in reliance upon Regulation S under the 1933 Act.

          (ii)   No General Solicitation. The Series A Capital Securities
                 -----------------------
     will be offered by approaching prospective Subsequent Purchasers on an
     individual basis. No general solicitation or general advertising (within
     the meaning of Rule 502(c) under the 1933 Act) will be used in the United
     States in connection with the offering of the Capital Securities.

          (iii)  Purchases by Non-Bank Fiduciaries. In the case of a non-bank
                 ---------------------------------
     Subsequent Purchaser of a Series A Capital Security acting as a fiduciary
     for one or more third parties, in connection with an offer and sale to such
     purchaser pursuant to clause (a) above, each third party shall, in the
     judgment of the applicable Initial Purchaser, be an Institutional
     Accredited Investor or a Qualified Institutional Buyer or a non-U.S. person
     outside the United States.

 
                                      22

          (iv)   Subsequent Purchaser Notification. Each Initial Purchaser will
                 ---------------------------------
     take reasonable steps to inform, and cause each of its U.S. affiliates to
     take reasonable steps to inform, persons acquiring Series A Capital
     Securities from such Initial Purchaser or affiliate, as the case may be, in
     the United States that the Series A Capital Securities (A) have not been
     and will not be registered under the 1933 Act, (B) are being sold to them
     without registration under the 1933 Act in reliance on Rule 144A or in
     accordance with another exemption from registration under the 1933 Act, as
     the case may be, and (C) may not be offered, sold or otherwise transferred
     except (1) to the Company, (2) outside the United States in accordance with
     Regulation S, or (3) inside the United States in accordance with (x) Rule
     144A to a person whom the seller reasonably believes is a Qualified
     Institutional Buyer that is purchasing such Securities for its own account
     or for the account of a Qualified Institutional Buyer to whom notice is
     given that the offer, sale or transfer is being made in reliance on Rule
     144A or (y) an exemption from registration under the 1933 Act (including
     the exemption provided by Rule 144), if available.

          (v)    Minimum Amount. No sale of the Series A Capital Securities to
                 --------------
     any one Subsequent Purchaser will be in blocks of less than U.S.$100,000
     liquidation amount.

          (vi)   Restrictions on Transfer. The transfer restrictions and the
                 ------------------------
     other provisions of the Declaration, including the legend required thereby,
     shall apply to the Series A Capital Securities except as otherwise agreed
     by the Offerors and the Initial Purchasers. Following the sale of the
     Series A Capital Securities by the Initial Purchasers to Subsequent
     Purchasers pursuant to the terms hereof, the Initial Purchasers shall not
     be liable or responsible to the Offerors for any losses, damages or
     liabilities suffered or incurred by the Offerors, including any losses,
     damages or liabilities under the 1933 Act, arising from or relating to any
     resale or transfer of any Capital Security.

          (vii)  Delivery of Offering Memorandum. Each Initial Purchaser will
                 -------------------------------
     deliver to each purchaser of the Series A Capital Securities from such
     Initial Purchaser, in connection with its original distribution of the
     Series A Capital Securities, a copy of the Final Offering Memorandum, as
     amended and supplemented at the date of such delivery.

          (b)    Covenants of the Offerors. Each of the Offerors, jointly and
severally, covenants with each Initial Purchaser as follows:

          (i)    Due Diligence. In connection with the original distribution of
                 -------------
     the Series A Capital Securities, the Offerors agree that, prior to any
     offer or sale of the 

 
                                      23

     Series A Capital Securities by the Initial Purchasers, the Initial
     Purchasers and counsel for the Initial Purchasers shall have the right to
     make reasonable inquiries into the business of the Trust, the Company and
     its subsidiaries. The Offerors also agree to provide answers to each
     prospective Subsequent Purchaser of Series A Capital Securities who so
     requests concerning the Trust, Company and its subsidiaries (to the extent
     that such information is available or can be acquired and made available to
     each prospective Subsequent Purchaser without unreasonable effort or
     expense and to the extent the provision thereof is not prohibited by
     applicable law or contractual restriction) and the terms and conditions of
     the offering of the Securities, as provided in the Offering Memorandums.

          (ii)   Integration. The Offerors agree that they will not and will
                 -----------
     cause their affiliates not to make any offer or sale of securities of the
     Offerors of any class if, as a result of the doctrine of "integration"
     referred to in Rule 502 under the 1933 Act, such offer or sale would render
     invalid (for the purpose of (i) the sale of the Series A Capital Securities
     by the Trust to the Initial Purchasers, (ii) the resale of the Series A
     Capital Securities by the Initial Purchasers to Subsequent Purchasers or
     (iii) the resale of the Series A Capital Securities by such Subsequent
     Purchasers to others) the exemption from the registration requirements of
     the 1933 Act provided by Section 4(2) thereof or by Rule 144A or by
     Regulation S thereunder or otherwise,
 
          (iii)  Rule 144A Information. The Company agrees that, in order to
                 ---------------------
     render the Series A Capital Securities eligible for resale pursuant to Rule
     144A under the 1933 Act, while any of the Series A Capital Securities
     remain outstanding, the Company will make available, upon request, to any
     holder of Series A Capital Securities or prospective purchasers of Series A
     Capital Securities the information specified in Rule 144A(d)(4), unless
     such information is furnished to the Commission pursuant to Section 13 or
     15(d) of the 1934 Act (such information, whether made available to holders
     or prospective purchasers or furnished to the Commission, is herein
     referred to as "Additional Information").

          (iv)   Restriction on Repurchases. Until the expiration of three years
                 --------------------------
     (or such shorter period as may hereafter be referred to in Rule 144(k) (or
     similar successor rule)) after the original issuance of the Series A
     Capital Securities, the Offerors will not, and will cause their affiliates
     not to, purchase or agree to purchase or otherwise acquire any Series A
     Capital Securities which are "restricted securities" (as such term is
     defined under Rule 144(a)(3) under the 1933 Act), whether as beneficial
     owner, or otherwise unless, immediately upon any such purchase, the
     Offerors or any affiliate shall submit such Series A Capital Securities to

 
                                      24

     the Trustee for cancellation; provided, that any affiliate which is an
                                   --------
     insurance company need not deliver such securities to the Trustee for
     cancellation for so long as such affiliate continues to hold such Series A
     Capital Securities for its own account.

          (c)    Resale Pursuant to Rule 903 of Regulation S or Rule 144A. Each
Initial Purchaser understands that the Series A Capital Securities have not been
and will not be registered under the 1933 Act and may not be offered or sold
within the United States or to, or for the account or benefit of, U.S. persons
except in accordance with Regulation S under the 1933 Act or pursuant to an
exemption from the registration requirements of the 1933 Act. Each Initial
Purchaser represents and agrees, that, except as permitted below, it has offered
and sold Series A Capital Securities and will offer and sell Series A Capital
Securities (i) as part of their distribution at any time and (ii) otherwise
until forty days after the later of the date upon which the offering of the
Series A Capital Securities commences and the Closing Time, only in accordance
with Rule 903 of Regulation S or Rule 144A under the 1933 Act or to
Institutional Accredited Investors. Accordingly, neither the Initial Purchasers
and their affiliates nor any persons acting on their behalf have engaged or will
engage in any directed selling efforts with respect to Series A Capital
Securities, and the Initial Purchasers, their affiliates and any person acting
on their behalf have complied and will comply with the offering restriction
requirements of Regulation S. Each Initial Purchaser agrees that, at or prior to
confirmation of a sale of Series A Capital Securities (other than a sale of
Series A Capital Securities pursuant to Rule 144A or to Institutional Accredited
Investors), it will have sent to each distributor, dealer or person receiving a
selling concession, fee or other remuneration that purchases Securities from it
or through it during the restricted period a confirmation or notice to
substantially the following effect:

                  "The Securities covered hereby have not been registered under
                  the United States Securities Act of 1933 (the "Securities
                  Act") and may not be offered or sold within the United States
                  or to or for the account or benefit of U.S. persons (i) as
                  part of their distribution at any time and (ii) otherwise
                  until forty days after the later of the date upon which the
                  offering of the Securities commenced and the date of closing,
                  except in either case in accordance with Regulation S or Rule
                  144A under the Securities Act. Terms used above have the
                  meaning given to them by Regulation S."

Terms used in the above paragraph have the meanings given to them by 
Regulation S.

Each Initial Purchaser severally represents and agrees that it has not entered
and will not enter into any contractual arrangements with respect to the
distribution of the Series A Capital Securities, except with its affiliates that
are Qualified Institutional Buyers or with the prior written consent of the
Offerors.


 
                                      25

          (d)    Compliance with United Kingdom Law. Each Initial Purchaser
represents and agrees that (i) it has not offered or sold and, prior to the
expiry of the period of six months from the date hereof, will not offer or sell
any Series A Capital Securities to persons in the United Kingdom except to
persons whose ordinary activities involve them in acquiring, holding, managing
or disposing of investments (as principal or agent) for the purposes of their
businesses or otherwise in circumstances which have not resulted and will not
result in an offer to the public in the United Kingdom within the meaning of the
Public Offers of Securities Regulations 1995; (ii) it has only issued or passed
on and will only issue or pass on in the United Kingdom any document received by
it in connection with the issue of the Series A Capital Securities to a person
who is of a kind described in Article 11(3) of the Financial Services Act 1986
(Investment Advertisements) (Exemptions) Order 1995 or is a person to whom such
document may otherwise lawfully be issued or passed on; and (iii) it has
complied and will comply with all applicable provisions of the Financial
Services Act 1986 with respect to anything done by it in relation to any Series
A Capital Securities in, from or otherwise involving the United Kingdom.

          (e)    Compliance with Other Laws. Each Initial Purchaser acknowledges
that no action has been taken to permit a public offering of the Series A
Capital Securities in any jurisdiction outside of the United States where action
would be required for such purpose. Each Initial Purchaser agrees that it will
not offer or sell any Series A Capital Securities in any jurisdiction outside of
the United States except under circumstances that will result in compliance with
all applicable laws thereof.

          SECTION 7.  Indemnification.
                      --------------- 

          (a)    The Offerors agree to jointly and severally indemnify and
hold harmless each Initial Purchaser and each person, if any, who controls any
Initial Purchaser within the meaning of Section 15 of the 1933 Act as follows:

          (i)    against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of an untrue statement or alleged
     untrue statement of a material fact contained in the Offering Memorandums,
     or the omission or alleged omission therefrom of a material fact required
     to be stated therein or necessary to make the statements therein, in the
     light of the circumstances under which they were made, not misleading;

          (ii)   against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue 

 
                                      26

     statement or omission, or any such alleged untrue statement or omission, if
     such settlement is effected with the written consent of the Offerors; and

          (iii)  against any and all expense whatsoever, as incurred (including
     fees and disbursements of counsel chosen by you), reasonably incurred in
     investigating, preparing or defending against any litigation, or
     investigation or proceeding by any governmental agency or body, commenced
     or threatened, or any claim whatsoever based upon any such untrue statement
     or omission, or any such alleged untrue statement or omission, to the
     extent that any such expense is not paid under subparagraph (i) or (ii)
     above;

provided, however, that this indemnity agreement does not apply to any loss,
- --------  -------
liability, claim, damage or expense to the extent arising out of an untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Offerors by any
Initial Purchaser through Merrill Lynch expressly for use in the Offering
Memorandums; and provided, further that the foregoing indemnity agreement with
                 --------  -------
respect to any untrue statement contained in or any omission from a preliminary
Offering Memorandum shall not inure to the benefit of any Initial Purchaser (or
any person who controls such Initial Purchaser within the meaning of Section 15
of the 1933 Act) from whom the person asserting any such loss, liability, claim,
damage or expense purchased any of the Series A Securities that are the subject
thereof if such person was not sent or given a copy of the Final Offering
Memorandum in the quantities requested by such Initial Purchaser and the loss,
claim, damage or liability of such Initial Purchaser results from an untrue
statement contained in or the omission from such preliminary Offering Memorandum
which was corrected in the Final Offering Memorandum.

          (b)    Each Initial Purchaser severally agrees to indemnify and hold
harmless the Company, its directors and officers, the Trust, the Administrative
Trustees and each person, if any, who controls the Company or the Trust within
the meaning of Section 15 of the 1933 Act, against any and all loss, liability,
claim, damage and expense described in the indemnity agreement in Section 7(a),
as incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Offering Memorandums in reliance
upon and in conformity with written information furnished to the Company or the
Trust by such Initial Purchaser through Merrill Lynch expressly for use in the
Offering Memorandums.

          (c)    Each indemnified party shall give prompt notice to each
indemnifying party of any action commenced against it in respect of which
indemnity may be sought hereunder, but failure to so notify an indemnifying
party shall not relieve it from any liability which it may have otherwise than
on account of this indemnity agreement. An indemnifying party may participate at
its own expense in the defense of such action. In no event shall the

 
                                      27

indemnifying party or parties be liable for the fees and expenses of more than
one counsel for all indemnified parties in connection with any one action or
separate but similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances.

          SECTION 8.  Contribution.
                      ------------
          In order to provide for just and equitable contribution in
circumstances under which the indemnity provided for in Section 7 is for any
reason held to be unenforceable by the indemnified parties although applicable
in accordance with its terms, the Offerors and the Initial Purchasers shall
contribute to the aggregate losses, liabilities, claims, damages and expenses of
the nature contemplated by such indemnity incurred by the Company, the Trust and
one or more of the Initial Purchasers, as incurred, in such proportions that (a)
the Initial Purchasers are responsible for that portion represented by the
percentage that the total commission for the Initial Purchasers appearing on the
cover page of the Final Offering Memorandum bears to the aggregate offering
price to investors of the Series A Capital Securities appearing thereon and (b)
the Offerors are responsible for the balance; provided, however, that no person
                                              --------  -------
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the 1933 Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this Section, each
person, if any, who controls an Initial Purchaser within the meaning of Section

          SECTION 10.  Termination of Agreement.
                       ------------------------
          (a)  Termination; General. The Initial Purchasers may terminate this
Agreement, by notice to the Offerors, at any time at or prior to the Closing
Time (i) if there has occurred any material adverse change in the financial
markets in the United Sates or any outbreak of hostilities or escalation thereof
or other calamity or crisis the effect of which on 

 
                                      28

the financial markets of the United States is such as to make it, in your
judgment, impracticable to market the Series A Capital Securities or to enforce
contracts for the sale of the Series A Capital Securities, or (ii) if trading in
any securities of the Company has been suspended by the Commission or the New
York Stock Exchange, or if trading generally on either the American Stock
Exchange or the New York Stock Exchange or in the over-the-counter market has
been suspended, or minimum or maximum prices for trading have been fixed, or
maximum ranges for prices for securities have been required, by any of such
exchange or by order of the Commission or any other governmental authority or
(iii) if a banking moratorium has been declared by either federal, New York,
Massachusetts or Delaware authorities, or (iv) if there has been, since the date
hereof or since the respective dates as of which information is given in the
Offering Memorandums, any material adverse change in the condition, financial or
otherwise, or in the earnings, business affairs or business prospects of the
Trust or the Company and its subsidiaries considered as one enterprise, whether
or not arising in the ordinary course of business, except that the announcement
of or execution of an agreement relating to the terms and conditions of the
Acquisition (as defined in the Offering Memorandum) will not be considered a
material adverse change for purposes of this clause (iv).

          (b)    Liabilities. If this Agreement is terminated pursuant to this
Section, such termination shall be without liability of any party to any other
party except as provided in Section 4 hereof, and provided further that Sections
1, 7 and 8 shall survive such termination and remain in full force and effect.

          SECTION 11.  Default by One or More of the Initial Purchasers.
                       ------------------------------------------------

          If one or more of the Initial Purchasers shall fail at the Closing
Time to purchase Securities which it or they are obligated to purchase under
this Agreement (the "Defaulted Securities"), the Initial Purchasers shall have
the right, within 24 hours thereafter, to make arrangements for one or more of
the non-defaulting Initial Purchasers, or any other Initial Purchasers, to
purchase all, but not less than all, of the Defaulted Securities in such amounts
as may be agreed upon and upon the terms herein set forth; if, however, the
Initial Purchasers shall not have completed such arrangements within such 24-
hour period, then this Agreement shall terminate without liability on the part
of any non-defaulting Initial Purchaser.

          No action taken pursuant to this Section shall relieve any defaulting
Initial Purchaser from liability in respect of its default.

          In the event of any such default which does not result in a
termination of this Agreement, either the Initial Purchasers or the Company
shall have the right to postpone the Closing Time until no later than February
5, 1997 in order to effect any required changes in the Offering Memorandums or
in any other documents or arrangements. As used herein, the 

 
                                      29

term "Initial Purchaser" includes any person substituted for an Initial
Purchaser under this Section 11.
