offering  price (or its equivalent (based on the applicable exchange rate at the

    During the first quarter of 1996,  UNUM America and First UNUM entered  into
an  agreement  for  the sale  of  their respective  group  tax-sheltered annuity
("TSA") businesses  to The  Lincoln National  Life Insurance  Company  ("Lincoln
Life"),  a part of Lincoln National Corporation, and to a new New York insurance
subsidiary of Lincoln Life. The sale, which is subject to regulatory  approvals,
involves  approximately 1,700 group contractholders  and assets under management
of  approximately  $3   billion.  The  agreement   initially  contemplates   the
reinsurance of these contracts under an indemnity reinsurance arrangement. These
contracts   will  then  be  reinsured  pursuant  to  an  assumption  reinsurance
arrangement upon consent  of the  TSA contractholders  and/or participants.  The
purchase  price (ceding commission)  at closing is  expected to be approximately
$70 million. It is anticipated  that it will take  several months to obtain  the
necessary approvals and otherwise close the sale. There is no guarantee that the
sale will close.
 
    On February 7, 1996, UNUM announced plans to merge Commercial Life Insurance
Company  into UNUM  America to accelerate  growth of its  special risk business,
increase its  commitment  to  the  association group  business  and  to  improve
operating  and capital efficiencies. The merger  is expected to become effective
on December 31, 1996, subject to regulatory approvals.
 
    On December 29, 1993,  UNUM filed suit in  the United States District  Court
for  the District  of Maine, seeking  a federal  income tax refund.  The suit is
based on a claim for a deduction in certain prior tax years, for $652 million in
cash and  stock  distributed  to  policyholders  in  connection  with  the  1986
conversion  of Union Mutual Life Insurance Company  to a stock company. UNUM has
fully paid, and provided  for in prior years'  financial statements, the tax  at
issue  in  this litigation.  On  May 23,  1996,  the District  Court  issued its
decision that the  distribution in  question was not  a deductible  expenditure.
UNUM  believes its claims are meritorious, and expects to appeal the decision to
the Court  of Appeals  for the  First Circuit.  The ultimate  recovery, if  any,
cannot be determined at this time.

    UNUM's  investment portfolio is concentrated in investment grade bonds. UNUM
evaluates total expected return after  consideration of associated expenses  and
losses,  within  criteria  established  for  each  product  line.  Product  line
investment strategies are developed to complement business risks by meeting  the
liquidity  and solvency requirements of each product. UNUM purchases assets with
maturities, expected cash  flows and prepayment  conditions that are  consistent
with these strategies. The
 
                                       4
<PAGE>
nature  and quality of the types of investments comply with policies established
by  management,  which  are  more  stringent  overall  than  the  statutes   and
regulations  imposed by the jurisdictions in which UNUM's insurance subsidiaries
are licensed.  UNUM's investments  are reported  in the  consolidated  financial
statements  at  net realizable  value or  net of  any applicable  allowances for
probable losses.
 
    During the second  quarter of 1995,  UNUM sold virtually  all of the  common
stock   portfolio  of   its  United   States  subsidiaries,   primarily  due  to
consideration of statutory  capital requirements associated  with investment  in
common  stocks and to increase future investment income. UNUM has reinvested the
proceeds from the  sale of the  common stock portfolio  primarily in  investment
grade  fixed  income  assets.  Dependent on  capital  considerations  and market
conditions, UNUM may invest in equity securities in the future.
 
    In November 1995, the  FASB issued "A Guide  to Implementation of  Statement
115  on Accounting for Certain Investments in Debt and Equity Securities," which
provided  a  one-time  opportunity  to  reassess  the  appropriateness  of   the
classifications  of securities  described in  FAS 115,  and to  reclassify fixed
maturities from the held to maturity category without calling into question  the
intent  to hold other debt securities to maturity in the future. On December 31,
1995, UNUM reassessed  its fixed maturity  portfolio and, as  allowed under  the
implementation guidance, reclassified fixed maturities with an amortized cost of
$6,082.8  million and a related  net unrealized gain of  $393.0 million from the
held to maturity category to available for sale.
 
    At December 31, 1995, the  fixed maturity portfolio included $139.4  million
of  below investment  grade bonds  (below "Baa")  recorded at  fair value, which
represented 1.5%  of  the  fixed  maturity  portfolio,  and  had  an  associated
amortized  cost of $133.8 million.  At December 31, 1994,  the carrying value of
below investment grade bonds included in the fixed maturity portfolio was $193.8
million, which represented  2.5% of  the fixed  maturity portfolio,  and had  an
associated  market value  of $193.4  million. The  percentage of  mortgage loans
delinquent 60 days or more on a contract delinquency basis was 0.2% and 1.8%  at
December 31, 1995, and 1994, respectively.

(a)  Net investment income  is comprised of investment  income (net of expenses)
    and net realized investment gains.
(b) Earnings  per share  before  cumulative effects  of accounting  changes  was
    $3.96.  Effective January 1, 1993,  the Company adopted Financial Accounting
    Standard No. 106, "Employers'  Accounting for Postretirement Benefits  Other
    than  Pensions," which decreased  net income by $32.1  million, or $0.40 per
    share, and Financial  Accounting Standard  No. 109,  "Accounting for  Income
    Taxes," which increased net income by $20.0 million, or $0.25 per share.
(c)  For purposes of computing the ratio  of earnings to fixed charges, earnings
    as adjusted consist of income from continuing operations before income taxes
    plus fixed  charges.  Fixed charges  consist  of interest  expense  and  the
    estimated interest portion of rent expense.

                                USE OF PROCEEDS
 
    Except  as set forth in a Prospectus  Supplement, the Company intends to use
the net proceeds from the sale of the Securities for general corporate purposes,
including working  capital, capital  expenditures, investment  in  subsidiaries,
refinancing   of  debt,  possible  future  business  acquisitions  and  for  the
repurchase of its Common Stock. The Company does not have any present plans, and
is not engaged in  any negotiations, for  the use of any  such proceeds, or  the
issuance  of  Common  Stock, in  any  future  acquisition. Any  proposal  to use
proceeds from any offering of Securities in connection with an acquisition  will
be disclosed in the Prospectus Supplement relating to such offering.
 
                         DESCRIPTION OF DEBT SECURITIES
 
    The following description sets forth certain general terms and provisions of
the  Debt  Securities  to  which  any  Prospectus  Supplement  may  relate.  The
particular terms of the Debt Securities offered by any Prospectus Supplement and
the extent, if any, to which such  general provisions may not apply to the  Debt
Securities so offered will be described in the Prospectus Supplement relating to
such Debt Securities.
 
    The  Senior Debt Securities are to be issued under an Indenture, dated as of
September 15,  1990  (the "Senior  Indenture"),  between UNUM  Corporation  (for
purposes   of  this   "Description  of   Debt  Securities,"   exclusive  of  its
subsidiaries, the "Company") and The Chase Manhattan Bank, N.A., as trustee. The
Subordinated Debt Securities are to be  issued under a separate Indenture  dated
as  of May 1, 1995 (the "Subordinated Indenture") between the Company and Mellon
Bank, N.A., as trustee. The Senior Indenture and the Subordinated Indenture  are
sometimes  referred to  collectively as the  "Indentures." Copies  of the Senior
Indenture and the Subordinated Indenture are filed or incorporated by  reference
as  exhibits to the Registration  Statement of which this  Prospectus is a part.
The Chase Manhattan Bank, N.A. and Mellon Bank, N.A. are hereinafter referred to
as the "Trustee." The  following summaries of certain  provisions of the  Senior
Debt  Securities, the  Subordinated Debt  Securities and  the Indentures  do not
purport to be complete and are subject  to, and are qualified in their  entirety
by reference to, all the provisions of the Indentures applicable to a particular
series  of Debt Securities, including the  definitions therein of certain terms.
Wherever particular Sections, Articles  or defined terms  of the Indentures  are
referred to, such Sections, Articles or defined terms are incorporated herein by
reference.  Article and  Section references  used herein  are references  to the
applicable Indenture. Except  as otherwise  indicated, the terms  of the  Senior
Indenture  and the Subordinated  Indenture are identical.  Capitalized terms not
otherwise defined herein shall have the meaning given in the Indentures.
 
GENERAL
 
    The  Indentures  do  not  limit  the  aggregate  principal  amount  of  Debt
Securities  which may be issued thereunder and each Indenture provides that Debt
Securities may be issued thereunder from time to time in one or more series. The
Debt Securities will be unsecured. Unless otherwise specified in the  Prospectus
Supplement,  the  Senior  Debt  Securities when  issued  will  be unsubordinated
obligations of the  Company and  will rank equally  and ratably  with all  other
unsecured  and unsubordinated indebtedness of the Company. The Subordinated Debt
Securities when issued  will be subordinated  in right of  payment to the  prior
payment in full of all Senior Indebtedness (as defined below) of the Company, as
described  under  "Subordination of  Subordinated  Debt Securities"  and  in the
Prospectus Supplement applicable to an offering of Subordinated Debt Securities.
Since the Company is a holding company, the right of the Company, and hence  the
right of creditors of the Company (including the Holders of Debt Securities), to
participate  in  any  distribution of  the  assets  of any  subsidiary  upon its
liquidation or reorganization or otherwise  is necessarily subject to the  prior
claims  of creditors of the subsidiary, except  to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized.
 
    Reference is made to  the Prospectus Supplement  relating to the  particular
Debt Securities offered thereby (the "Offered Debt Securities") which sets forth
whether the Offered Debt Securities shall be
 
                                       8
<PAGE>
Senior  Debt Securities or Subordinated Debt  Securities, and further sets forth
the following terms, where applicable, of  the Offered Debt Securities: (1)  the
title of the Offered Debt Securities; (2) any limit on their aggregate principal
amount;  (3) whether they  are to be  issuable in temporary  or permanent global
form; (4) the  price(s) (expressed as  a percentage of  the aggregate  principal
amount thereof) at which they will be issued; (5) the date(s) on which they will
mature;  (6) the rate(s) (which  may be fixed, floating  or adjustable) at which
they will bear  interest, if any,  and the  date from which  such interest  will
accrue;  (7) the dates  on which such  interest will be  payable and the Regular
Record Dates for  such Interest  Payment Dates;  (8) any  mandatory or  optional
sinking fund or analogous provisions; (9) any index or formula used to determine
the  amount of payments of principal of  and premium, if any, and interest; (10)
the date, if any, after which and  the price(s) at which the Company may  redeem
them  at  its  option;  (11) the  currency  or  currencies  (including composite
currencies) of payment of principal of and premium, if any, and interest thereon
if other  than U.S.  dollars  (the "Specified  Currency");  (12) the  terms  and
conditions,  if  any, pursuant  to which  the  Subordinated Debt  Securities are
convertible into  or  exchangeable  for  Common Stock  or  other  securities  or
property  of the Company;  (13) the Person  to whom any  interest on the Offered
Debt Securities will be  payable, if other  than the Person  in whose name  such
Offered  Debt Securities  are registered  on any  Regular Record  Date; (14) the
place or places where principal of (and  premium, if any) and interest, if  any,
on  Offered Debt Securities will be payable; (15) if other than denominations of
$1,000 and any integral multiple thereof, the denominations in which the Offered
Debt Securities will be issuable; (16) any event or events of default applicable
with respect to the Offered Debt Securities in addition to those provided in the
applicable Indenture;  (17) any  other  covenant or  warranty included  for  the
benefit  of the  Offered Debt  Securities in  addition to  (and not inconsistent
with) those  included  in the  applicable  Indenture  for the  benefit  of  Debt
Securities  of all series,  or any other  covenant or warranty  included for the
benefit of  the Offered  Debt Securities  in lieu  of any  covenant or  warranty
included  in the Indentures for the benefit  of Debt Securities of all series or
any provision that any covenant or warranty included in the applicable Indenture
for the benefit of Debt Securities of all series shall not be for the benefit of
the Offered Debt Securities, or any combination of such covenants, warranties or
provisions; and (18) any other terms. (Section 301) Debt Securities may also  be
issued  under the Indentures upon the  exercise of Warrants. See "Description of
Warrants."
 
    The Indentures do not contain any provisions that afford Holders of the Debt
Securities protection in the event of a highly leveraged or similar  transaction
involving the Company.
 
    Offered  Debt Securities  may be issued  at a substantial  discount to their
principal amount  (the "Original  Issue  Discount Securities").  Certain  United
States  Federal income tax and other considerations applicable to Original Issue
Discount Securities,  and to  Offered Debt  Securities that  are denominated  in
other  than  U.S.  dollars,  will  be  described  in  the  applicable Prospectus
Supplement.
 
    The Indentures provide  the Company  with the  ability, in  addition to  the
ability to issue Offered Debt Securities with terms different from those of Debt
Securities  previously issued, to "reopen" a previous  issue of a series of Debt
Securities and issue additional Offered Debt Securities of such series. (Section
301)
 
DENOMINATIONS, REGISTRATION AND TRANSFER
 
    Unless otherwise  provided  in  an  applicable  Prospectus  Supplement  with
respect  to  a  series  of  Offered  Debt  Securities,  Offered  Debt Securities
denominated in U.S. dollars  will be issued only  in denominations of $1,000  or
any  integral  multiple  thereof  without  coupons.  The  Prospectus  Supplement
relating to a  series of  Offered Debt Securities  denominated in  a foreign  or
composite currency will specify the denominations thereof. (Section 302) Offered
Debt  Securities  of any  series  will be  exchangeable  for other  Offered Debt
Securities of the same series containing identical terms and provisions and of a
like aggregate principal amount and containing identical terms and provisions of
different authorized denominations. (Section 305) Offered Debt Securities may be
issuable under the Indentures  in temporary or  permanent global form.  (Section
202) See "Global Securities."
 
                                       9
<PAGE>
    Unless  otherwise  indicated  in an  applicable  Prospectus  Supplement, the
principal office of the Trustee  in The City of New  York will be designated  as
the  Company's Paying  Agent for payments  with respect to  Debt Securities. Any
other Paying Agents in the United States initially designated by the Company for
the Offered Debt Securities will be named in the related Prospectus  Supplement.
The  Company may at any  time designate additional Paying  Agents or rescind the
designation of any Paying Agents or approve a change in the office through which
any Paying Agent acts, except  that the Company will  be required to maintain  a
Paying  Agent in each Place  of Payment for such series.  All monies paid by the
Company to a Paying Agent for the  payment of principal of and premium, if  any,
and interest, if any, on any Debt Security which remains unclaimed at the end of
two  years after such principal,  premium or interest shall  have become due and
payable will be  repaid to  the Company,  and the  Holder of  such Offered  Debt
Security  will thereafter look only to the Company for payment thereof. (Section
1003)
 
GLOBAL SECURITIES
 
    If any Offered Debt Securities are issuable in temporary or permanent global
form, the applicable Prospectus Supplement  will describe the circumstances,  if
any,  under which  beneficial owners of  interests in any  such permanent global
Debt Security may exchange such interests for definitive Offered Debt Securities
of such series and of like tenor and principal amount in any authorized form and
denomination. Principal of and  any premium and interest  on a permanent  global
Debt  Security  will  be  payable  in the  manner  described  in  the applicable
Prospectus Supplement.
 
CERTAIN COVENANTS IN THE INDENTURES
 
    LIMITATIONS ON SALES OF RESTRICTED SUBSIDIARIES' CAPITAL STOCK.  The Company
will not sell, transfer or otherwise dispose of any shares of capital stock of a
Restricted Subsidiary  (other  than directors'  qualifying  shares or  sales  to
Restricted  Subsidiaries), and it  will not permit  any Restricted Subsidiary to
sell, transfer or otherwise dispose of any shares of capital stock of any  other
Restricted  Subsidiary (other than for directors'  qualifying shares or sales or
other transfers to the Company or to a Restricted Subsidiary), unless the entire
capital stock of such Restricted Subsidiary at the time owned by the Company and
its Restricted  Subsidiaries  shall  be disposed  of  at  the same  time  for  a
consideration consisting of cash or other property, which, in the opinion of the
Board  of Directors of the Company, is at least equal to the fair value thereof.
(Section 1006)
 
    For purposes of the Indentures,  "Restricted Subsidiary" means each of  UNUM
Life  Insurance  Company  of America,  First  UNUM Life  Insurance  Company, and
Colonial Companies, Inc., as well as any successor to all or a principal part of
the business of any such subsidiary, any subsidiary which owns or holds  capital
stock  of any such subsidiary and any other subsidiary which the Company's Board
of Directors designates as a Restricted Subsidiary. (Section 101) The Restricted
Subsidiaries accounted for approximately 90% of the consolidated revenues of the
Company during 1995  and approximately  91% of  the consolidated  assets of  the
Company at December 31, 1995.
 
LIMITATIONS ON LIENS ON RESTRICTED SUBSIDIARIES' CAPITAL STOCK.
 
    The  Company will not, and  it will not permit  any Restricted Subsidiary at
any time directly or  indirectly to, create, assume,  incur, or permit to  exist
any  indebtedness secured by a pledge, lien, or other encumbrance on the capital
stock of any  Restricted Subsidiary without  making effective provision  whereby
the  Debt Securities then outstanding (and, if  the Company so elects, any other
indebtedness ranking on a parity with the Debt Securities) shall be equally  and
ratably   secured  with  such  secured  indebtedness   so  long  as  such  other
indebtedness shall be secured. (Section 1007)
 
CONVERSION RIGHTS
 
    The  terms  on  which  Subordinated  Debt  Securities  of  any  series   are
convertible  into  or  exchangeable  for Common  Stock  or  other  securities or
property of the Company will be set forth in the Prospectus Supplement  relating
thereto.  Such  terms  shall  include provisions  as  to  whether  conversion or
exchange is mandatory,  at the  option of  the Holder or  at the  option of  the
Company, and may include provisions
 
                                       10
<PAGE>
pursuant  to which the number  of shares of Common  Stock or other securities of
the Company to be received by the Holders of Subordinated Debt Securities  would
be  calculated according to the market price of Common Stock or other securities
of the Company as of a time stated in the Prospectus Supplement. The  conversion
price of any Subordinated Debt Securities of any series that is convertible into
Common  Stock of  the Company  may be  adjusted for  any stock  dividends, stock
splits, reclassification, combinations or similar transactions, as set forth  in
the applicable Prospectus Supplement. (Article Fourteen).
 
SUBORDINATION OF SUBORDINATED DEBT SECURITIES
 
    Unless  otherwise  indicated  in the  Prospectus  Supplement,  the following
provisions will apply to the Subordinated Debt Securities.
 
    The Subordinated  Debt Securities  will,  to the  extent  set forth  in  the
Subordinated  Indenture, be subordinate in right of payment to the prior payment
in full of all Senior Indebtedness.  Upon any payment or distribution of  assets
to  creditors  upon any  liquidation,  dissolution, winding  up, reorganization,
assignment  for  the  benefit  of  creditors,  marshalling  of  assets  or   any
bankruptcy,  insolvency, debt restructuring or similar proceedings in connection
with any insolvency  or bankruptcy  proceeding of  the Company,  the Holders  of
Senior  Indebtedness  will  first be  entitled  to  receive payment  in  full of
principal of  (and  premium,  if any)  and  interest,  if any,  on  such  Senior
Indebtedness  before the  Holders of  the Subordinated  Debt Securities  will be
entitled to receive or retain  any payment in respect  of the principal of  (and
premium,  if  any) or  interest, if  any, on  the Subordinated  Debt Securities.
(Section 1302)
 
    By reason of such subordination, in the event of liquidation or  insolvency,
creditors  of  the Company  may recover  less, ratably,  than Holders  of Senior
Indebtedness and may recover more, ratably, than the Holders of the Subordinated
Debt Securities.
 
    In the event of  the acceleration of the  maturity of any Subordinated  Debt
Securities,  the Holders of  all Senior Indebtedness outstanding  at the time of
such acceleration  will first  be entitled  to receive  payment in  full of  all
amounts  due thereon before the Holders of the Subordinated Debt Securities will
be entitled to receive any payment upon the principal of (or premium, if any) or
interest, if any, on the Subordinated Debt Securities. (Section 1303)
 
    No payments on  account of principal  (or premium, if  any) or interest,  if
any,  in respect of the Subordinated Debt  Securities may be made if there shall
have occurred and be continuing a default in any payment with respect to  Senior
Indebtedness,  or an  event of default  with respect to  any Senior Indebtedness
resulting in  the acceleration  of  the maturity  thereof,  or if  any  judicial
proceeding shall be pending with respect to any such default. (Section 1304) For
purposes  of the subordination provisions, the payment, issuance and delivery of
cash,  property  or  securities  (other  than  stock  and  certain  subordinated
securities  of the Company) upon conversion of a Subordinated Debt Security will
be deemed to constitute payment on account of the principal of such Subordinated
Debt Security.
 
    The Subordinated  Indenture does  not limit  or prohibit  the incurrence  of
additional Senior Indebtedness, which may include indebtedness that is senior to
the  Subordinated Debt Securities,  but subordinate to  other obligations of the
Company. The Senior  Debt Securities  constitute Senior  Indebtedness under  the
Subordinated Indenture.
 
    "Senior  Indebtedness"  is  defined  to  include  all  amounts  due  on  and
obligations in connection with any of the following, whether outstanding at  the
date  of  execution  of the  Subordinated  Indenture or  thereafter  incurred or
created:
 
    (a)  indebtedness,  obligations   and  other   liabilities  (contingent   or
otherwise) of the Company for money borrowed, or evidenced by bonds, debentures,
notes or similar instruments;
 
                                       11
<PAGE>
    (b)   reimbursement  obligations   and  other   liabilities  (contingent  or
otherwise)  of  the  Company  with  respect  to  letters  of  credit,   bankers'
acceptances  issued for the account  of the Company or  with respect to interest
rate protection agreements or currency exchange or purchase agreements;
 
    (c) obligations  and liabilities  (contingent or  otherwise) in  respect  of
leases  by the  Company as lessee  which, in conformity  with generally accepted
accounting principles, are accounted for as capitalized lease obligations on the
balance sheet of the Company;
 
    (d) all direct or indirect guarantees  or similar agreements in respect  of,
and  obligations  or  liabilities  (contingent  or  otherwise)  to  purchase  or
otherwise acquire or otherwise to assure a creditor against loss of the  Company
in  respect  of,  indebtedness,  obligations or  liabilities  of  another Person
described in clauses (a) through (c);
 
    (e) any indebtedness  described in clauses  (a) through (d)  secured by  any
mortgage,  pledge, lien or other encumbrance existing on property which is owned
or held by the Company, regardless  of whether the indebtedness secured  thereby
shall have been assumed by the Company; and
 
    (f)  any  and  all deferrals,  renewals,  extensions and  refundings  of, or
amendments, modifications  or supplements  to, any  indebtedness, obligation  or
liability  of the kind described in clauses  (a) through (e); unless in any case
in  the  instrument  creating  or  evidencing  such  indebtedness,   obligation,
liability,  guaranty, assumption, deferral, renewal,  extension or refunding, it
is provided that such indebtedness, obligation, liability, guaranty, assumption,
deferral, renewal, extension  or refunding involved  is not senior  in right  of
payment  to the Subordinated  Debt Securities or that  such indebtedness is PARI
PASSU with or junior to the Subordinated Debt Securities. (Section 101)
 
    The Prospectus  Supplement  may further  describe  the provisions,  if  any,
applicable  to  the  subordination  of the  Subordinated  Debt  Securities  of a
particular series.
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
    The Company,  without  the  consent  of  any  Holders  of  Outstanding  Debt
Securities,  may consolidate or  merge with or  into any Person,  or transfer or
lease its assets substantially as an entirety  to any Person, or may acquire  or
lease  the assets of any Person, provided that: (a) the successor formed by such
consolidation or into which  the Company is merged  or which acquires or  leases
the  assets of the Company  substantially as an entirety  is organized under the
laws of any United States jurisdiction and assumes the Company's obligations  on
the  Debt Securities and under the applicable Indenture; (b) after giving effect
to the transaction, no  Event of Default  (and no event  which, after notice  or
lapse of time or both, would become an Event of Default) shall have happened and
be continuing; and (c) certain other conditions are met. (Article Eight)
 
EVENTS OF DEFAULT
 
    Under  the Indentures, the following will  be Events of Default with respect
to Debt  Securities of  a particular  series: (a)  the Company  defaults in  the
payment of interest on any Debt Security of that series when due and payable and
the  Default continues for a period of 30  days; (b) the Company defaults in the
payment of any principal of  and premium, if any, on  any Debt Security of  that
series when due and payable at maturity, upon redemption or otherwise, or in the
deposit  of any sinking fund payment when due by the terms of a Debt Security of
that series; (c) the Company  fails to comply with or  perform any of its  other
agreements, covenants or warranties in the Debt Securities of that series or the
Indenture in respect of Debt Securities of that series and the Default continues
for  60 days after written  notice as provided in  the applicable Indenture; (d)
there shall be a default by the  Company or any Restricted Subsidiary under  any
(i)  debt for money borrowed (including Debt Securities of any series other than
that series), (ii) mortgage, indenture or other instrument under which there may
be issued or may  be secured or evidenced  any indebtedness for money  borrowed,
(iii)  guarantee of payment for money borrowed  or (iv) debt evidenced by bonds,
debentures, notes or other similar instruments (excluding trade accounts payable
or accrued liabilities arising  in the normal course  of business which are  not
overdue by more
 
                                       12
<PAGE>
than  90 days or which are being contested in good faith) and such default shall
result in such indebtedness becoming due prior to its stated maturity; PROVIDED,
HOWEVER, a default shall exist under this  clause (d) only if all such  defaults
relate  to  such indebtedness  or such  guarantees  with an  aggregate principal
amount in excess of $5,000,000, the acceleration of which has not been rescinded
or annulled within 10  days after written notice  as provided in the  applicable
Indenture; (e) certain events of bankruptcy, insolvency or reorganization of the
Company  or  any  Restricted Subsidiary;  and  (f)  any other  Event  of Default
provided with  respect to  Debt Securities  of that  series. (Section  501)  The
applicable  Trustee or the  Holders of at  least 25% in  principal amount of the
Outstanding Debt Securities  of that series  (each series acting  as a  separate
class)  may declare all unpaid principal of and accrued interest (or such lesser
amount as may be provided for in the Debt Securities of that series) on all then
Outstanding Debt Securities of that series to be due and payable immediately  if
an  Event  of  Default  (other than  one  in  (e) above)  with  respect  to Debt
Securities of  such  series  shall  occur  and be  continuing  at  the  time  of
declaration. If an Event of Default as specified in (e) above occurs, all unpaid
principal  and accrued interest (or such lesser amount as may be provided for in
the Debt Securities of that series)  shall IPSO FACTO become and be  immediately
due  and payable without any other declaration or act on the part of the Trustee
or any Holder. (Section 502)
 
    At any time after a declaration  of acceleration has been made with  respect
to  Debt Securities of any series, the Holders of a majority in principal amount
of the Outstanding Debt Securities of that series may rescind any declaration of
acceleration with  respect  to  the  Debt Securities  of  that  series  and  its
consequences,  (a) if  the rescission  would not  conflict with  any judgment or
decree; (b) if all existing Events  of Defaults with respect to Debt  Securities
of  that series  have been  cured or waived  except non-payment  of principal or
interest on Debt Securities of that series that has become due solely because of
the acceleration; and (c) to the extent that payment of such interest is lawful,
interest upon overdue interest at the rate or rates prescribed therefore in such
Debt Securities has been paid. (Section  502) Any Event of Default with  respect
to  Debt Securities of any series may be  waived by the Holders of a majority in
principal amount of the Outstanding Debt Securities of that series, except in  a
case  of failure to pay principal or premium, if any, or interest on, or deposit
of any sinking fund payment  with respect to, any  Debt Security of that  series
for  which payment or deposit had not been  subsequently made or in respect of a
covenant or provision which cannot be modified or amended without the consent of
the Holder of each Outstanding Debt  Security of such series affected.  (Section
504)
 
    If any event which is, or after notice or lapse of time or both would become
an  Event of Default (a "Default") occurs with respect to Debt Securities of any
series and it  is known to  the applicable  Trustee, the Trustee  shall mail  to
Holders  of Debt Securities  of that series  a notice of  Default within 90 days
after it occurs unless  such Default shall have  been cured or waived,  PROVIDED
that  except in  the case of  a Default  in the payment  of the  principal of or
premium, if any,  or interest  on, any  Debt Security of  any series  or in  the
making  of any sinking fund  payment payable with respect  to Debt Securities of
any series, the Trustee may withhold the notice  if and so long as the board  of
directors,  the  executive  committee  or  a  trust  committee  of  directors or
Responsible Officers of the  Trustee in good  faith determines that  withholding
the  notice is in the interests of Holders of Debt Securities of that series and
PROVIDED, FURTHER, that in the case of any Default of the character specified in
clause (c) under  "Events of  Default" with respect  to Debt  Securities of  any
series,  no notice to  Holders shall be given  until at least  30 days after the
occurrence thereof. (Section 602)
 
    Reference is made  to the Prospectus  Supplement relating to  any series  of
Debt  Securities which are Original Issue Discount Securities for the particular
provisions relating  to the  principal amount  of such  Original Issue  Discount
Securities  due upon the occurrence of any Event of Default and the continuation
thereof.
 
    The Holders  of a  majority  in principal  amount  of the  Outstanding  Debt
Securities  of a series may direct the  time, method and place of conducting any
proceeding for any remedy  available to the Trustee  or exercising any trust  or
power  conferred on the Trustee with respect  to Debt Securities of such series,
 
                                       13
<PAGE>
PROVIDED that the Trustee may refuse to follow any directions that conflict with
any law or the Indenture, are unduly prejudicial to the rights of other  Holders
of  that series,  or would involve  the Trustee in  personal liability. (Section
505)
 
    In case an Event of Default shall occur and be continuing, the Trustee shall
exercise such of its  rights and powers under  the applicable Indenture and  use
the  same degree of care  and skill in their exercise  as a prudent person would
exercise or  use under  the circumstances  in the  conduct of  his own  affairs.
(Section  601)  Before  proceeding to  exercise  any  right or  power  under the
applicable Indenture  at the  direction of  such Holders,  the Trustee  will  be
entitled  to receive from such Holders  security or indemnity satisfactory to it
against the costs,  expenses and liabilities  which might be  incurred by it  in
complying with any such direction. (Section 603)
 
MODIFICATION AND WAIVER
 
    With  certain exceptions, modification or amendment of the Indentures or the
rights of Holders of the  Debt Securities of any series  may be effected by  the
Company  and the Trustee with the consent of  the Holders of at least 66 2/3% in
principal amount  of the  Outstanding Debt  Securities of  each series  affected
thereby,  PROVIDED  that  no such  modification  or amendment  may,  without the
written consent  of  the  Holder  of each  Outstanding  Debt  Security  affected
thereby,  (a) change the Stated Maturity of the principal of, or any installment
of principal of,  or interest on,  any Debt Security;  (b) reduce the  principal
amount of, or the interest on, any Debt Security or any premium payable upon the
redemption  thereof  or reduce  the  amount of  principal  of an  Original Issue
Discount Security which could be declared due and payable upon an  acceleration;
(c) change the Place of Payment or coin or currency of any payment of principal,
any  premium or interest on any Debt Security; (d) impair the right to institute
suit for the enforcement of any payment on or with respect to any Debt Security;
(e) reduce the percentage in principal amount of the Outstanding Debt Securities
of any  series,  the  consent  of  whose Holders  is  required  to  approve  any
supplemental  indenture,  to waive  compliance  with certain  provisions  of the
applicable Indenture or certain defaults  thereunder and their consequences,  or
to  reduce quorum or voting requirements  applicable to meetings of Holders; (f)
in the  case of  Subordinated Debt  Securities, adversely  change the  right  to
convert  or exchange, including decreasing the conversion rate or increasing the
conversion price of such  Subordinated Debt Securities; (g)  in the case of  the
Subordinated  Indenture, modify the subordination provisions in a manner adverse
to the Holders of any Subordinated Debt Securities; or (h) modify the  foregoing
requirements  in (a) through (g) above, requiring  the consent of each Holder of
each Outstanding  Debt Security  affected  thereby, or  the percentage  of  such
Holders  required to waive past defaults, or the percentage of such Holders that
may rescind an acceleration, except to increase any such percentage, and  except
to  provide that other provisions of the Indentures cannot be modified or waived
without the consent  of the Holder  of each Outstanding  Debt Security  affected
thereby.  (Section 902) Except  with respect to  certain fundamental provisions,
the Holders  of at  least a  majority in  principal amount  of Outstanding  Debt
Securities  of any series may, with respect  to such series, waive past defaults
under the Indentures and waive compliance by the Company with certain provisions
of the Indentures. (Section 513)
 
SATISFACTION AND DISCHARGE OF INDENTURES
 
    The Indentures generally provide that  the Company may terminate certain  of
its obligations under the Debt Securities of any series and under the Indentures
(with  respect to  such series) if  (i) all  the Debt Securities  of such series
previously authenticated and  delivered (other  than lost,  destroyed or  stolen
Debt  Securities that have been replaced or  paid or for whose payment money has
been deposited in trust) have been delivered to the Trustee for cancellation and
the Company  has  paid  all  sums  payable by  it  thereunder,  (ii)  such  Debt
Securities  of such series have matured or will mature within one year or all of
them are  to  be  called  for redemption  within  one  year  under  arrangements
satisfactory  to the Trustee for giving the notice of redemption and the Company
irrevocably deposits  with  the Trustee  money  or U.S.  Government  Obligations
sufficient to pay principal of, premium, if any, and interest on the Outstanding
Debt  Securities of such series that are  due or will become due upon redemption
or maturity, as the case
 
                                       14
<PAGE>
may be,  and to  pay all  other  sums payable  by it  thereunder or  (iii)  upon
compliance  with certain conditions specified in  the Indentures, 123 days after
the Company  makes the  deposit with  the Trustee  of money  or U.S.  Government
Obligations  specified  in  clause  (ii).  In such  case,  Holders  of  the Debt
Securities must look to the deposited money for payment. (Section 401)
 
    The Indentures further  provide that if  the Company has  made the  election
provided  by  clause (iii)  above, it  may elect  either (a)  to defease  and be
discharged from any and all obligations  with respect to the Debt Securities  of
such  series, except for the obligations to register the transfer or exchange of
such Debt  Securities, to  replace temporary  or mutilated,  destroyed, lost  or
stolen  Debt Securities, to maintain an office  or agency in respect of the Debt
Securities, and to hold moneys for payment in trust ("legal defeasance") or  (b)
to  be released from its obligations with respect to the Debt Securities of such
series under the covenant  default (except with respect  to the covenant to  pay
principal  and  interest)  and cross-acceleration  provisions  under  "Events of
Default" and  from the  restrictions described  under certain  covenants in  the
Indentures,  including "Limitations on Sales of Restricted Subsidiaries' Capital
Stock" and "Limitations  on Liens  on Restricted  Subsidiaries' Capital  Stock,"
and, in the case of Subordinated Debt Securities, the provisions described under
"Subordination  of Subordinated  Debt Securities" ("covenant  defeasance"). As a
condition to legal defeasance or  covenant defeasance, the Company must  deliver
to  the Trustee an  opinion of counsel  (as specified in  the Indentures) to the
effect that the Holders of the Debt Securities of such series will not recognize
income, gain or loss for United States  Federal income tax purposes as a  result
of  such legal defeasance or  covenant defeasance and will  be subject to United
States Federal income tax  on the same  amounts, in the same  manner and at  the
same  times as  would have been  the case  if such legal  defeasance or covenant
defeasance had not occurred. In the case of legal defeasance under clause (a) or
covenant defeasance under  clause (b) above,  a ruling of  the Internal  Revenue
Service may be delivered in lieu of such opinion. (Section 401)
 
    Under  current United States Federal income  tax law, legal defeasance would
likely be treated as a taxable exchange of such Debt Securities for interests in
the defeasance trust. As  a consequence, a Holder  would recognize gain or  loss
equal  to the difference between the Holder's tax basis for such Debt Securities
and the value of the Holder's  interest in the defeasance trust, and  thereafter
would be required to include in income its share of the income, gain and loss of
the  defeasance trust. Under current Federal income tax law, covenant defeasance
would likely  not be  treated as  a taxable  exchange of  such Debt  Securities.
Purchasers  of  such  Debt Securities  should  consult their  tax  advisors with
respect to the more particular tax consequences to them of such legal defeasance
and covenant defeasance, including the applicability and effect of United States
Federal income and other tax law.
 
    The Company may  exercise its legal  defeasance option with  respect to  the
Debt  Securities  of  such series,  notwithstanding  its prior  exercise  of its
covenant defeasance  option.  If  the Company  exercises  its  legal  defeasance
option,  payment of such  Debt Securities may  not be accelerated  because of an
Event of  Default. If  the  Company exercises  its covenant  defeasance  option,
payment  of such Debt Securities may not  be accelerated because of the covenant
default (except with respect to the covenant to pay principal and interest)  and
cross-acceleration provisions or certain of the covenants, including those noted
under  clause (b) above. However, if such  an acceleration were to occur because
of other defaults, the  realizable value at the  acceleration date of the  money
and  U.S. Government Obligations in the defeasance  trust could be less than the
principal and interest then  due on such Debt  Securities, because the  required
deposit  in the defeasance trust is based  upon scheduled cash flows rather than
market value, which will vary depending  upon interest rates and other  factors.
(Section 401)
 
    The term "U.S. Government Obligations" is defined to mean direct obligations
of  the United  States for  the payment of  which its  full faith  and credit is
pledged, or obligations of a person controlled or supervised by and acting as an
agency or  instrumentality of  the United  States and  the payment  of which  is
unconditionally  guaranteed as a full faith  and credit obligation by the United
States which, in either case,  are not callable or  redeemable at the option  of
the issuer thereof, and shall also include a depositary receipt issued by a bank
(as  defined  in  Section  3(a)(2)  of the  Securities  Act)  as  custodian with
 
                                       15
<PAGE>
respect to  any  such U.S.  Government  Obligations  or a  specific  payment  of
principal  of or interest on  any such U.S. Government  Obligations held by such
custodian for the  account of the  holder of such  depositary receipt,  PROVIDED
that  (except as required by  law) such custodian is  not authorized to make any
deduction from the amount payable to the holder of such depositary receipt  from
any  amount  received  by  the  custodian  in  respect  of  the  U.S. Government
Obligations or the  specific payment  of principal of  or interest  on the  U.S.
Government Obligations evidenced by such depositary receipt. (Section 101)

                         DESCRIPTION OF PREFERRED STOCK
 
    The following description sets forth certain general terms and provisions of
the Preferred Stock to which any Prospectus Supplement may relate. Certain other
terms  of  a particular  series  of Preferred  Stock  will be  described  in the
Prospectus Supplement relating to that series. If so indicated in the Prospectus
Supplement, the terms of  any such series  may differ from  the terms set  forth
below.  The description of  certain provisions of the  Preferred Stock set forth
below and in any Prospectus  Supplement does not purport  to be complete and  is
subject  to  and  qualified  in  its  entirety  by  reference  to  the Company's
Certificate of Incorporation and the certificate of designation relating to each
such series  of Preferred  Stock, which  will be  filed with  the Commission  in
connection with the offering of such series of Preferred Stock.
 
GENERAL
 
    Under  the Company's Certificate of Incorporation, the Board of Directors is
authorized to fix and determine the  terms, limitations and relative rights  and
preferences  of any class of preferred stock, including, without limitation, any
voting rights thereof, to divide and issue any of the classes of preferred stock
in series, and to fix  and determine the variations  among series to the  extent
permitted  by  law.  The  Company  has  authorized  1,000,000  shares  of Junior
Participating Preferred Stock for issuance upon
 
                                       16
<PAGE>
exercise of certain preferred share  purchase rights associated with each  share
of   outstanding  Common  Stock  as  provided   in  the  Rights  Agreement.  See
"Description of Common Stock--Share Purchase Rights Plan,--Description of Junior
Participating Preferred Stock."
 
    The Preferred Stock  shall have  the dividend,  liquidation, redemption  and
voting  rights  set  forth below  unless  otherwise provided  in  the Prospectus
Supplement relating to a particular series of Preferred Stock. Reference is made
to the Prospectus Supplement relating to a particular series of Preferred  Stock
offered thereby for specific terms including: (1) the designation and the number
of  shares offered; (2) the amount of  liquidation preference per share; (3) the
price at which such Preferred  Stock will be issued;  (4) the dividend rate  (or
method  of calculation), the  dates on which dividends  will be payable, whether
such dividends will be cumulative or noncumulative and, if cumulative, the dates
from which dividends will  commence to cumulate; (5)  any redemption or  sinking
fund  provisions; (6) any conversion or  exchange rights; and (7) any additional
voting, dividend,  liquidation,  redemption,  sinking  fund  and  other  rights,
preferences, privileges, limitations and restrictions.
 
    The Preferred Stock offered hereby will be issued in one or more series. The
holders  of  Preferred  Stock will  have  no  preemptive rights.  Any  shares of
Preferred Stock  sold  hereunder  will  be fully  paid  and  nonassessable  upon
issuance  against full payment of the  purchase price therefor. Unless otherwise
specified in  the  Prospectus Supplement  relating  to a  particular  series  of
Preferred  Stock, each  series of Preferred  Stock will  rank on a  parity as to
dividends and  liquidation rights  in all  respects with  each other  series  of
Preferred Stock (other than the Junior Participating Preferred Stock).
 
DIVIDEND RIGHTS
 
    Holders  of the Preferred Stock of each  series will be entitled to receive,
when, as and if declared by the Board of Directors of the Company, out of  funds
legally  available therefor, cash dividends  at such rates and  on such dates as
are set forth in the Prospectus Supplement relating to such series of  Preferred
Stock.  Different series of the Preferred Stock  may be entitled to dividends at
different rates or based upon different methods of determination. Such rate  may
be  fixed or variable or both. Each such dividend will be payable to the holders
of record as they appear on the stock books of the Company on such record  dates
as  will be fixed by the Board of  Directors of the Company or a duly authorized
committee thereof.  Dividends  on any  series  of  the Preferred  Stock  may  be
cumulative  or noncumulative, as provided  in the Prospectus Supplement relating
thereto.
 
RIGHTS UPON LIQUIDATION
 
    In the event  of any  voluntary or involuntary  liquidation, dissolution  or
winding up of the Company, the holders of each series of Preferred Stock will be
entitled  to receive out of assets of  the Company available for distribution to
stockholders, before any  distribution of assets  is made to  holders of  Common
Stock or any other class of stock ranking junior to such series of the Preferred
Stock upon liquidation, liquidating distributions in the amount set forth in the
Prospectus  Supplement relating to such series of Preferred Stock plus an amount
equal to accrued and unpaid dividends for the then current dividend period  and,
if  such series of the  Preferred Stock is cumulative,  for all dividend periods
prior thereto, all  as set forth  in the Prospectus  Supplement with respect  to
such shares.
 
REDEMPTION
 
    The  terms, if any,  on which shares of  a series of  Preferred Stock may be
subject to optional or mandatory  redemption, in whole or  in part, will be  set
forth in the Prospectus Supplement relating to such series.
 
CONVERSION
 
    The  terms, if  any, on which  shares of  any series of  Preferred Stock are
convertible into Common  Stock will be  set forth in  the Prospectus  Supplement
relating thereto. Such terms may include provisions
 
                                       17
<PAGE>
for  conversion, either mandatory, at the option of the holder, or at the option
of the  Company, in  which case  the  number of  shares of  Common Stock  to  be
received  by the holders of Preferred Stock would be calculated as of a time and
in the manner stated in the Prospectus Supplement.
 
TRANSFER AGENT AND REGISTRAR
 
    The transfer  agent,  registrar  and dividend  disbursement  agent  for  the
Preferred  Stock will be designated in the applicable Prospectus Supplement. The
registrar for shares of Preferred Stock will send notices to shareholders of any
meetings at  which  holders of  the  Preferred Stock  have  the right  to  elect
directors of the Company or to vote on any other matter.
 
VOTING RIGHTS
 
    The  holders  of Preferred  Stock of  a  series offered  hereby will  not be
entitled to vote except  as indicated in the  Prospectus Supplement relating  to
such series of Preferred Stock or as required by applicable law.
 
                          DESCRIPTION OF COMMON STOCK
 
GENERAL
 
    Subject  to  the  rights of  the  holders  of any  shares  of  the Company's
Preferred Stock which may  at the time be  outstanding, holders of Common  Stock
are  entitled to  such dividends as  the Board  of Directors may  declare out of
funds legally  available therefor.  The  holders of  Common Stock  will  possess
exclusive  voting  rights in  the Company,  except  to the  extent the  Board of
Directors specifies voting  power with  respect to any  Preferred Stock  issued.
Except  as hereinafter  described, holders of  Common Stock are  entitled to one
vote for each share  of Common Stock,  but will not have  any right to  cumulate
votes  in the election of directors. In the event of liquidation, dissolution or
winding up of the Company, the holders of Common Stock are entitled to  receive,
after  payment of all of the Company's debts  and liabilities and of all sums to
which holders of any  Preferred Stock may be  entitled, the distribution of  any
remaining  assets  of the  Company.  Holders of  the  Common Stock  will  not be
entitled to preemptive rights  with respect to any  shares which may be  issued.
Any  shares of Common Stock sold hereunder will be fully paid and non-assessable
upon issuance against full payment of the purchase price therefor. First Chicago
Trust Company of New York is the transfer agent for the Common Stock. The Common
Stock is listed on the  New York Stock Exchange  and the Pacific Stock  Exchange
under the symbol "UNM."
 
CERTAIN PROVISIONS
 
    The  provisions of  the Company's  Certificate of  Incorporation and By-Laws
which are summarized below may be deemed to have an anti-takeover effect and may
delay, defer or prevent  a tender offer or  takeover attempt that a  stockholder
might  consider in  such stockholder's  best interest,  including those attempts
that might result  in a premium  over the market  price for the  shares held  by
stockholders.
 
    CLASSIFIED BOARD.  The Board of Directors is divided into three classes that
are  elected for staggered  three-year terms. A  director may be  removed by the
stockholders, but  only for  cause, and  only  by the  affirmative vote  of  the
holders,  voting as a single class, of 80%  or more of the total number of votes
entitled to be cast by all holders  of the voting stock which shall include  all
capital  stock  of  the Company  which  by its  terms  may vote  on  all matters
submitted to stockholders of the Company generally.
 
    ISSUANCE OF PREFERRED STOCK.  Pursuant to the Certificate of  Incorporation,
the  Board  of Directors  by  resolution may  establish  one or  more  series of
Preferred Stock  having  such number  of  shares, designation,  relative  voting
rights,   dividend  rates,   liquidation  and  other   rights,  preferences  and
limitations as  may be  fixed by  the  Board of  Directors without  any  further
stockholder  approval. Such  rights, preferences, privileges  and limitations as
may be  established  could have  the  effect  of impeding  or  discouraging  the
acquisition of control of the Company.
 
                                       18
<PAGE>
    BUSINESS  COMBINATIONS.  In  addition, the Certificate  of Incorporation and
By-Laws of the Company contain  supermajority voting provisions relating to  the
approval  of business  combinations with  certain stockholders.  Pursuant to the
Company's Certificate  of Incorporation,  any Business  Combination (as  defined
therein,  which term  includes a  merger, sale of  all or  substantially all its
assets, the  adoption  of  a  plan  of  liquidation  and  similar  extraordinary
corporate  transactions)  with  (i)  any person  (other  than  the  Company, its
subsidiaries, certain employee benefit plans of the Company and the trustees  of
such  plans) who is the beneficial owner of 10% or more of the UNUM Voting Stock
(as defined below)  or (ii)  any person  who is  an Affiliate  or Associate  (as
defined  in Rule  12b-2 of  the Exchange  Act) of  the Company  and who  was the
beneficial owner of 10% or more of the UNUM Voting Stock at any time in the  two
years  prior  to the  date in  question  (each such  person, a  "UNUM Interested
Stockholder") must  be approved  by a  supermajority vote,  unless the  Business
Combination  has  been approved  by the  vote  of a  majority of  the Continuing
Directors (as defined below) of the  Company's Board of Directors. "UNUM  Voting
Stock" means all capital stock of the Company which by its terms may vote on all
matters   submitted  to  stockholders  of  the  Company  generally.  "Continuing
Director" means any Board of  Directors member who while  serving as a Board  of
Directors  member is not an Affiliate or Associate or representative of the UNUM
Interested Stockholder and who was a  Board of Directors member before the  UNUM
Interested Stockholder became such and includes certain successors to such Board
of   Directors  members.  The  required   supermajority  vote  consists  of  the
affirmative vote of the  holders of (i)  80% or more of  the UNUM Voting  Stock,
voting together as a single class, and (ii) at least a majority of the shares of
UNUM  Voting Stock not held by  the UNUM Interested Stockholder, voting together
as a single class.
 
    AMENDMENTS TO THE CERTIFICATE  OF INCORPORATION.   Under the Certificate  of
Incorporation,  the  amendment  of,  repeal  of  or  adoption  of  any provision
inconsistent  with  certain  provisions  of  the  Certificate  of  Incorporation
relating  to (i) the election of the  Board of Directors, its powers and related
matters requires the  affirmative vote of  the holders  of at least  80% of  the
outstanding  UNUM  Voting Stock,  voting together  as a  single class,  and (ii)
Business Combinations with UNUM Interested  Stockholders and the required  votes
for amendments of the Certificate of Incorporation requires the affirmative vote
of  the holders specified  in clause (i)  above and the  affirmative vote of the
holders of at least a majority of the outstanding UNUM Voting Stock which is not
beneficially owned  by any  UNUM Interested  Stockholder, voting  together as  a
single  class. The above  supermajority voting requirements do  not apply to any
amendment, repeal  or adoption  recommended by  the Board  of Directors  of  the
Company  if a majority of  the Board of Directors of  the Company then in office
consists of persons who would be eligible to serve as Continuing Directors.
 
    AMENDMENTS TO THE BY-LAWS.   The Certificate of Incorporation provides  that
the  By-Laws may be amended  by the affirmative vote  of a majority of directors
present at a meeting of the Board of  Directors at which a quorum is present  or
by  the affirmative vote of the holders of  at least 80% of all outstanding UNUM
Voting Stock, voting together as a single class.
 
    STOCKHOLDER PROPOSAL PROCEDURES.   The By-Laws  require any stockholder  who
wants  to present a proposal for action by the stockholders at an annual meeting
to deliver a written  notice to the  Secretary of the Company.  To be timely,  a
stockholder's  notice  must be  delivered  to, or  mailed  and received  at, the
principal executive offices of the Company, not less than 60 days nor more  than
90  days prior  to the  date of the  annual meeting,  unless less  than 75 days'
notice or prior public disclosure of the date of such meeting has been given  or
made  to the stockholders, in which case a stockholder's notice must be received
no later than the close of business on  the 15th day following the day on  which
such notice was mailed or such disclosure was made.
 
SHARE PURCHASE RIGHTS PLAN
 
    On  March  13,  1992,  the  Board of  Directors  of  the  Company  adopted a
stockholder rights plan  and declared a  dividend distribution of  one right  (a
"Right") for each outstanding share of Common Stock to
 
                                       19
<PAGE>
stockholders  of record at the  close of business on  March 23, 1992. Each Right
entitles the registered holder to purchase from the Company a unit consisting of
one one-hundredth of a share (a "Unit") of Junior Participating Preferred Stock,
at a  purchase price  of $150  per Unit,  subject to  adjustment (the  "Purchase
Price"). The terms of the Junior Participating Preferred Stock are such that one
Unit is essentially equivalent to one share of Common Stock. The description and
terms  of the Rights are set forth in  a Rights Agreement, dated as of March 13,
1992 and  amended as  of June  19, 1996  (as amended,  the "Rights  Agreement"),
between the Company and First Chicago Trust Company of New York, as rights agent
(the "Rights Agent").
 
    Initially,   the  Rights  are  attached  to  all  outstanding  Common  Stock
certificates,  and   no  separate   certificates  evidencing   Rights   ("Rights
Certificates")  are distributed. The Rights will  separate from the Common Stock
and a "Distribution  Date" will  occur upon  the earlier  of (i)  ten (10)  days
following  a  public  announcement  that  a person  or  group  of  affiliated or
associated persons (an "Acquiring Person")  has acquired, or obtained the  right
to  acquire, beneficial ownership  of 10% or  more of the  outstanding shares of
Common Stock, except for persons or a group of affiliated or associated  persons
who  become the  beneficial owner of  10% or  more of the  outstanding shares of
Common Stock solely as a result of a reduction in the number of shares of Common
Stock outstanding  due to  a repurchase  of shares  by the  Company unless  such
person or group thereafter acquires additional shares representing 1% or more of
the  outstanding Common  Stock (the "Stock  Acquisition Date") or  (ii) ten (10)
business days  (or  such  later date  as  may  be determined  by  the  Board  of
Directors)  following the announcement of a  tender offer or exchange offer that
would result  in a  person or  group beneficially  owning 10%  or more  of  such
outstanding  shares of Common Stock.  However, if the Board  of Directors of the
Company determines that any  person who would otherwise  be an Acquiring  Person
has  become such  inadvertently, then such  person will not  become an Acquiring
Person if certain conditions are satisfied, including divestiture by such person
of beneficial ownership of the shares of Common Stock that would have  otherwise
caused such person to become an Acquiring Person.
 
    Until  the Distribution Date, (i) the Rights will be evidenced by the Common
Stock certificates and will be transferred with and only with such Common  Stock
certificates,  (ii) new  Common Stock certificates  issued after  March 23, 1992
contain a notation incorporating  the Rights Agreement  by reference, and  (iii)
the surrender for transfer of any certificates for Common Stock outstanding will
also  constitute the  transfer of  the Rights  associated with  the Common Stock
represented by  such certificates.  The  Rights are  not exercisable  until  the
Distribution  Date and will expire  at the close of  business on March 13, 2002,
unless earlier  redeemed by  the  Company as  described below  (the  "Expiration
Date").
 
    In  the event that (i) a Person becomes an Acquiring Person (except pursuant
to an offer for all outstanding shares of Common Stock which at least a majority
of the members of the Board of Directors who are not officers of the Company and
who are not representatives, nominees, affiliates or associates of an  Acquiring
Person  determine  to be  fair to  and otherwise  in the  best interests  of the
Company and its stockholders  (a "Fair Offer")) or  (ii) an Acquiring Person  or
any  of its affiliates or associates shall  merge into or otherwise combine with
the Company in a transaction in  which the Company is the surviving  corporation
and  the Common Stock remains outstanding and  unchanged, each holder of a Right
will thereafter have the right to  receive, upon exercise, Common Stock (or,  in
certain  circumstances, cash, property  or other securities of  the Company or a
reduction in the Purchase Price) having a value equal to two times the  exercise
price  of  the  Right.  Notwithstanding  any  of  the  foregoing,  following the
occurrence of any of  the events set  forth in this  paragraph, all Rights  that
are,  or (under certain  circumstances specified in  the Rights Agreement) were,
beneficially owned by  an Acquiring Person  or an associate  or affiliate of  an
Acquiring  Person will  be null  and void.  However, Rights  are not exercisable
following the occurrence of any of the events set forth in this paragraph  until
such  time as the  Rights are no longer  redeemable by the  Company as set forth
below.
 
    In the event that, at any time following the Stock Acquisition Date, (i) the
Company is acquired  in a merger  or other business  combination transaction  in
which the Company is not the surviving corporation
 
                                       20
<PAGE>
(other  than a  merger described  in the preceding  paragraph or  a merger which
follows, and is at  the same price  as, a Fair  Offer), or (ii)  50% or more  of
UNUM's  assets or earning power  is sold or transferred,  each holder of a Right
(except Rights which previously  have become null and  void as set forth  above)
shall  thereafter have the right to receive,  upon exercise, common stock of the
acquiring company having a value  equal to two times  the exercise price of  the
Right. The events set forth in this paragraph and in the preceding paragraph are
referred to as the "Triggering Events."
 
    At  any time after there is an Acquiring Person and prior to the acquisition
by such Acquiring Person  of 50% or  more of the  outstanding Common Stock,  the
Board  of Directors  may exchange  the Rights  (other than  Rights owned  by the
Acquiring Person which have become  null and void), in whole  or in part, at  an
exchange  ratio of one share of Common Stock or one Unit of Junior Participating
Preferred Stock (or a share or unit of another series of the Company's preferred
stock having equivalent rights, preferences  and privileges) per Right  (subject
to adjustment).
 
    At  any time until ten  (10) days following the  Stock Acquisition Date, the
Company may redeem the Rights in whole, but not in part, at a price of $.01  per
Right  (the "Redemption Price"), which is payable in cash, Common Stock or other
consideration deemed appropriate by the Board of Directors. Immediately upon the
action of the Board of Directors  ordering redemption of the Rights, the  Rights
will  terminate and the only  right of the holders of  Rights will be to receive
the Redemption Price.
 
    The Purchase Price payable, and the number of shares of Junior Participating
Preferred Stock or other securities or  property issuable, upon exercise of  the
Rights are subject to adjustment from time to time to prevent dilution.
 
    Until a Right is exercised, the holder thereof, as such, will have no rights
as  a stockholder  of the Company,  including, without limitation,  the right to
vote  or   to  receive   dividends.  Stockholders   may,  depending   upon   the
circumstances,  recognize taxable  income in  the event  that the  Rights become
exercisable for Common Stock (or other consideration) or for common stock of the
acquiring company as set forth above.
 
    The Rights  have  certain  anti-takeover  effects.  The  Rights  will  cause
substantial  dilution to a person or group  that attempts to acquire the Company
in a manner which causes  the Rights to become  exercisable unless the offer  is
conditioned  on  substantially all  the  Rights being  acquired.  This potential
dilution may have the effect of delaying, deferring or discouraging attempts  to
acquire  control of the Company which are not approved by the Company's Board of
Directors. However, the  Rights should not  interfere with any  merger or  other
business combination approved by the Company's Board of Directors.
 
DESCRIPTION OF JUNIOR PARTICIPATING PREFERRED STOCK
 
    GENERAL.    In connection  with the  Rights  Agreement, 1,000,000  shares of
Junior Participating  Preferred  Stock have  been  reserved and  authorized  for
issuance  by  the  Board  of  Directors of  the  Company.  No  shares  of Junior
Participating Preferred Stock are outstanding as of the date of this Prospectus.
The following  statements with  respect to  the Junior  Participating  Preferred
Stock  do not purport to be complete  and are subject to the detailed provisions
of the Certificate of Incorporation and the certificate of designation  relating
to  the Junior Participating Preferred Stock (the "Certificate of Designation"),
which are  filed  as  exhibits  to the  Registration  Statement  of  which  this
Prospectus is a part.
 
    RANKING.   The Junior Participating Preferred Stock shall rank junior to all
other series of the Company's Preferred Stock as to the payment of dividends and
the distribution of assets,  unless the terms of  any such series shall  provide
otherwise.
 
    DIVIDENDS  AND DISTRIBUTIONS.   Subject to the prior  and superior rights of
the holders of any  shares of any  series of Preferred  Stock ranking prior  and
superior  to the shares of Junior  Participating Preferred Stock with respect to
dividends, the holders of shares  of Junior Participating Preferred Stock  shall
be  entitled to receive, when, as and if  declared by the Board of Directors out
of funds legally available for
 
                                       21
<PAGE>
that purpose, quarterly dividends payable in  cash on the 19th day of  February,
May,  August and November in each year  (each such date being referred to herein
as "Quarterly Dividend Payment Date") commencing on the first Quarterly Dividend
Payment Date after  the first  issuance of  a share or  fraction of  a share  of
Junior  Participating Preferred  Stock, in an  amount per share  (rounded to the
nearest cent) equal to the  greater of (a) $5.00  or (b) (subject to  adjustment
upon  certain dilutive events) 100  times the aggregate per  share amount of all
cash dividends, and 100 times the  aggregate per share amount (payable in  kind)
of  all non-cash dividends or other  distributions other than a dividend payable
in shares of Common Stock or a  subdivision of the outstanding shares of  Common
Stock  (by reclassification or  otherwise), declared on  the Common Stock, since
the immediately preceding Quarterly Dividend  Payment Date, or, with respect  to
the first Quarterly Dividend Payment Date, since the first issuance of any share
or fraction of a share of Junior Participating Preferred Stock.
 
    The  Company  shall  declare  a  dividend  or  distribution  on  the  Junior
Participating Preferred  Stock  immediately  after it  declares  a  dividend  or
distribution  on the Common  Stock (other than  a dividend payable  in shares of
Common Stock); provided  that, in the  event no dividend  or distribution  shall
have  been declared on the Common Stock  during the period between any Quarterly
Dividend Payment Date and the next subsequent Quarterly Dividend Payment Date, a
dividend of $5.00 per  share on the Junior  Participating Preferred Stock  shall
nevertheless be payable on such subsequent Quarterly Dividend Payment Date.
 
    VOTING  RIGHTS.   The holders  of shares  of Junior  Participating Preferred
Stock shall have  the following voting  rights: (a) subject  to adjustment  upon
certain  dilutive  events, each  share of  Junior Participating  Preferred Stock
shall entitle the holder thereof to 100 votes on all matters submitted to a vote
of the stockholders  of the  Company; (b) except  as otherwise  provided by  the
Certificate  of  Designation  or  by  law,  the  holders  of  shares  of  Junior
Participating Preferred Stock and  the holders of shares  of Common Stock  shall
vote together as one class on all matters submitted to a vote of stockholders of
the  Company;  and (c)  if at  any  time dividends  on any  Junior Participating
Preferred Stock shall  be in arrears  in an  amount equal to  six (6)  quarterly
dividends  thereon, the occurrence of such  contingency shall mark the beginning
of a period  (herein called a  "default period") which  shall extend until  such
time  when all accrued and unpaid  dividends for all previous quarterly dividend
periods and for the  current quarterly dividend period  on all shares of  Junior
Participating Preferred Stock then outstanding shall have been declared and paid
or  set apart for payment. During each  default period, all holders of Preferred
Stock (including  holders  of the  Junior  Participating Preferred  Stock)  with
dividends  in arrears in an amount equal to six (6) quarterly dividends thereon,
voting as a class, irrespective of series, shall have the right to elect two (2)
Directors, until the expiration of a default period.
 
    LIQUIDATION, DISSOLUTION OR WINDING UP.  Upon any liquidation (voluntary  or
otherwise),  dissolution or winding up of  the Company, no distribution shall be
made to the holders of shares of stock ranking junior (either as to dividends or
upon liquidation,  dissolution  or  winding  up)  to  the  Junior  Participating
Preferred  Stock  unless,  prior  thereto,  the  holders  of  shares  of  Junior
Participating Preferred Stock shall have received $250 per share, plus an amount
equal to accrued and unpaid dividends and distributions thereon, whether or  not
declared,  to the date of such  payment (the "Series A Liquidation Preference").
Following the payment of the full amount of the Series A Liquidation Preference,
no additional distributions  shall be made  to the holders  of shares of  Junior
Participating  Preferred Stock unless,  prior thereto, the  holders of shares of
Common Stock shall have received an  amount per share (the "Common  Adjustment")
equal  to  the  quotient  obtained  by dividing  (i)  the  Series  A Liquidation
Preference by (ii)  100 (as  appropriately adjusted  to reflect  such events  as
stock  splits, stock dividends and recapitalizations  with respect to the Common
Stock) (such number in  clause (ii) immediately above  being referred to as  the
"Adjustment  Number"). Following the payment of the  full amount of the Series A
Liquidation Preference and the Common  Adjustment in respect of all  outstanding
shares  of Junior Participating Preferred  Stock and Common Stock, respectively,
holders of Junior Participating Preferred Stock and
 
                                       22
<PAGE>
holders of shares of Common Stock shall receive their ratable and  proportionate
share  of the remaining assets to be  distributed in the ratio of the Adjustment
Number to one (1) with  respect to such Preferred Stock  and Common Stock, on  a
per share basis, respectively.
 
    In  the event,  however, that there  are not sufficient  assets available to
permit  payment  in  full  of  the  Series  A  Liquidation  Preference  and  the
liquidation  preferences of all  other series of preferred  stock, if any, which
rank on  a parity  with  the Junior  Participating  Preferred Stock,  then  such
remaining  assets shall  be distributed  ratably to  the holders  of such parity
shares in proportion to their respective liquidation preferences. In the  event,
however,  that there  are not sufficient  assets available to  permit payment in
full of the Common Adjustment, then  such remaining assets shall be  distributed
ratably to the holders of Common Stock.
 
    CONSOLIDATION,  MERGER,  ETC.   In  case the  Company  shall enter  into any
consolidation, merger, combination or other  transaction in which the shares  of
Common  Stock are exchanged for or changed  into other stock or securities, cash
and/or any  other  property,  then  in  any such  case,  the  shares  of  Junior
Participating  Preferred Stock shall at the  same time be similarly exchanged or
changed in an  amount per  share (subject  to adjustment  upon certain  dilutive
events)  equal  to 100  times the  aggregate amount  of stock,  securities, cash
and/or any other property (payable in kind),  as the case may be, into which  or
for which each share of Common Stock is changed or exchanged.
 
    REDEMPTION.   The outstanding shares of Junior Participating Preferred Stock
may be redeemed at  the option of the  Board of Directors in  whole, but not  in
part,  at any time, or from time to time, at a cash price per share equal to 105
percent of (i)  the product of  the Adjustment Number  times the Average  Market
Value  (as such term is hereinafter defined)  of the Common Stock, plus (ii) all
dividends which on the redemption date have accrued on the shares to be redeemed
and have not been paid, or declared and a sum sufficient for the payment thereof
set apart, without interest.  The "Average Market Value"  is the average of  the
closing  sale prices  of the Common  Stock during the  30-day period immediately
preceding the date before the redemption date on the Composite Tape for New York
Stock Exchange Listed Stocks, or, if such  stock is not quoted on the  Composite
Tape,  on the New York Stock  Exchange, or, if such stock  is not listed on such
Exchange, on the  principal United States  securities exchange registered  under
the Exchange Act, on which such stock is listed, or, if such stock is not listed
on  any such exchange, the average of the  closing sale prices with respect to a
share of  Common Stock  during such  30-day period,  as quoted  on the  National
Association  of  Securities Dealers,  Inc.  Automated Quotations  System  or any
system then in use,  or, if no  such quotations are  available, the fair  market
value of the Common Stock as determined by the Board of Directors in good faith.
 
                            DESCRIPTION OF WARRANTS
 
    The  Company  may  issue  Warrants,  including  Warrants  to  purchase  Debt
Securities, Preferred Stock, Common  Stock or other  securities of the  Company.
Warrants may be issued independently or together with any such securities of the
Company  and may be attached to or separate from such securities of the Company.
The Warrants  are  to  be  issued under  warrant  agreements  (each  a  "Warrant
Agreement")  to be entered into between the Company and a bank or trust company,
as warrant  agent (the  "Warrant  Agent"), all  as shall  be  set forth  in  the
Prospectus Supplement relating to Warrants being offered pursuant thereto.
 
WARRANTS
 
    The  applicable Prospectus  Supplement will  describe the  terms of Warrants
offered thereby, the Warrant Agreement relating to such Warrants and the warrant
certificates representing such Warrants, including the following: (1) the  title
of  such Warrants; (2) the securities of the Company for which such Warrants are
exercisable; (3) the aggregate number of such Warrants; (4) the price or  prices
at which such Warrants will be issued; (5) the currency or currencies, including
composite  currencies or currency units, in which the price of such Warrants may
be   payable;    (6)    the    procedures    and    conditions    relating    to
 
                                       23
<PAGE>
the  exercise of  such Warrants;  (7) the designation  and terms  of any related
securities of the Company with which such Warrants are issued, and the number of
such Warrants issued with each such security; (8) the date, if any, on and after
which such Warrants and the related securities of the Company will be separately

commence,  and the date  on which such  right shall expire;  (10) the maximum or
minimum number of  such Warrants  which may  be exercised  at any  time; (11)  a
discussion  of material United States Federal income tax considerations, if any;
(12) any other  terms of  such Warrants  and terms,  procedures and  limitations
relating  to the exercise of such Warrants; and (13) the terms of the securities
of the Company purchasable upon exercise of such Warrants.
 
    Warrant certificates  will  be exchanged  for  new warrant  certificates  of
different  denominations, and Warrants  may be exercised  at the corporate trust
office of the  Warrant Agent  or any other  office indicated  in the  Prospectus
Supplement.  Prior  to  the  exercise of  their  Warrants,  holders  of Warrants
exercisable for Debt Securities will  not have any of  the rights of holders  of
the  Debt Securities purchasable upon such exercise  and will not be entitled to
payments of principal  (or premium, if  any) or  interest, if any,  on the  Debt
Securities  purchasable  upon  such exercise.  Prior  to the  exercise  of their
Warrants for shares of Preferred Stock or Common Stock, holders of such Warrants
will not have  any rights  of holders  of the  Preferred Stock  or Common  Stock
purchasable upon such exercise and will not be entitled to dividend payments, if
any,  or voting rights of  the Preferred Stock or  Common Stock purchasable upon
such exercise.
 
EXERCISE OF WARRANTS
 
    Each Warrant will entitle the holder  of Warrants to purchase for cash  such
principal  amount or such number  of securities of the  Company at such exercise
price as shall in each case be set forth in, or be determinable as set forth in,
the Prospectus Supplement relating  to the Warrants  offered thereby. After  the
close of business on the expiration date, unexercised Warrants will become void.
 
    Warrants may be exercised as set forth in the Prospectus Supplement relating
to  the  Warrants  offered thereby.  Upon  receipt  of payment  and  the warrant
certificate properly completed and duly  executed at the corporate trust  office
of the Warrant Agent or any other office indicated in the Prospectus Supplement,
the  Company will,  as soon as  practicable, forward  the securities purchasable
upon such exercise. If less than all of the Warrants represented by such warrant
certificate are exercised,  a new  warrant certificate  will be  issued for  the
remaining Warrants.
 
                             FOREIGN CURRENCY RISKS
 
GENERAL
 
    EXCHANGE  RATES AND  EXCHANGE CONTROLS.   An  investment in  Debt Securities
denominated in other than  U.S. dollars entails significant  risks that are  not
associated  with a similar investment in a security denominated in U.S. dollars.
Such risks include, without limitation,  the possibility of significant  changes
in  rates of exchange between the U.S. dollar and the various foreign currencies
or composite currencies, and the  possibility of the imposition or  modification
of  foreign exchange  controls by either  the U.S. or  foreign governments. Such
risks generally depend on economic and  political events over which the  Company
has  no control. In recent years, rates  of exchange between the U.S. dollar and
certain foreign currencies have been highly volatile, and such volatility may be
expected to continue in the future. Fluctuations in any particular exchange rate
that have  occurred in  the past  are not  necessarily indicative,  however,  of
fluctuations  in the rate that  may occur during the  term of any Debt Security.
Depreciation of the Specified Currency other than U.S. dollars against the  U.S.
dollar  would result in a decrease in  the effective yield of such Debt Security
below its coupon rate, and  in certain circumstances could  result in a loss  to
the investor on a U.S. dollar basis.
 
    Governments  have imposed  from time  to time and  may in  the future impose
exchange controls that could affect exchange  rates as well as the  availability
of a specified foreign currency at a Debt Security's
 
                                       24
<PAGE>
maturity. Even if there are no actual exchange controls, it is possible that the
Specified  Currency for any  particular Debt Security would  not be available at
such Debt Security's maturity. In that  event, the Company will repay such  Debt
Security at maturity in U.S. dollars on the basis of the most recently available
Exchange Rate.
 
    This  Prospectus does not  describe all the  risks of an  investment in Debt
Securities denominated in other than U.S. dollars. Prospective investors  should
consult  their own financial and  legal advisors as to  the risks entailed by an
investment in  Debt Securities  denominated  in other  than U.S.  dollars.  Debt
Securities  denominated  in  other  than U.S.  dollars  are  not  an appropriate
investment  for  investors  who  are  unsophisticated  about  foreign   currency
transactions.
 
    Currently,  there are limited facilities in the United States for conversion
of U.S. dollars into certain foreign currencies, and vice versa.
 
    Unless otherwise  specified in  the Prospectus  Supplement, Debt  Securities
denominated  in other than U.S.  dollars or European currency  units will not be
sold in, or to residents of, the country issuing the Specified Currency in which
particular Debt Securities are  denominated. The information  set forth in  this
Prospectus   is  directed  to  prospective  purchasers  who  are  United  States
residents, and the  Company disclaims any  responsibility to advise  prospective
purchasers who are residents of countries other than the United States as to any
matters  that  may  affect the  purchase,  holding,  or receipt  of  payments of
principal of and interest  on the Debt Securities.  Such persons should  consult
their own financial and legal advisors with regard to such matters.
 
    GOVERNING  LAW AND JUDGMENTS.   The Debt Securities will  be governed by and
construed in  accordance with  the laws  of the  State of  New York.  Under  the
Judiciary  Law of the State of  New York, a judgment in  an action based upon an
obligation denominated in a currency other than U.S. dollars will be rendered in
the foreign  currency  of the  underlying  obligation and  converted  into  U.S.
dollars  at the  rate of  exchange prevailing on  the date  of the  entry of the
judgment or decree.
 
EXCHANGE RATE AND CONTROLS FOR SPECIFIED CURRENCIES
 
    For any Debt Security denominated in other than U.S. dollars, the Prospectus
Supplement relating to such Debt Securities will contain information  concerning
exchange rates. The information concerning exchange rates will be furnished as a
matter  of information only and should not be regarded as indicative of the rate
of or trends in future fluctuations in currency exchange rates.
 
                              PLAN OF DISTRIBUTION
 
    The Company may  sell Securities to  or through underwriters,  and also  may
sell Securities directly to other purchasers or through agents.
 
    The  distribution of the Securities may be effected from time to time in one
or more transactions at  a fixed price  or prices, which may  be changed, or  at
market  prices  prevailing  at the  time  of  sale, at  prices  related  to such
prevailing market prices or at negotiated prices.
 
    In  connection  with  the  sale  of  Securities,  underwriters  may  receive
compensation  from the Company  or from purchasers of  Securities, for whom they
may act  as agents,  in  the form  of  discounts, concessions,  or  commissions.
Underwriters  may sell  Securities to or  through dealers, and  such dealers may
receive compensation in the form of discounts, concessions, or commissions  from
the underwriters and/or commissions from the purchasers for whom they may act as
agents.  Underwriters, dealers, and agents  that participate in the distribution
of Securities may be deemed to be underwriters, and any discounts or commissions
they receive from the Company, and any  profit on the resale of Securities  they
realize  may be deemed  to be underwriting discounts  and commissions, under the
Securities Act. Any such underwriter or  agent will be identified, and any  such
compensation  received from  the Company  will be  described, in  the Prospectus
Supplement.
 
                                       25
<PAGE>
    Each series of Securities  will be a new  issue with no established  trading
market,  other  than the  Common Stock  which is  listed on  the New  York Stock
Exchange and the  Pacific Stock Exchange.  Any Common Stock  sold pursuant to  a
Prospectus  Supplement will  be listed  on such  exchanges, subject  to official
notice of issuance. The Company may elect to list any series of Debt Securities,
Preferred Stock or Warrants on an exchange, but is not obligated to do so. It is
possible that  one  or more  underwriters  may make  a  market in  a  series  of
Securities,  but will not be  obligated to do so  and may discontinue any market
making at any time without  notice. Therefore, no assurance  can be given as  to
the liquidity of the trading market for the Securities.
 
    Under  agreements  the Company  may enter  into, underwriters,  dealers, and
agents who  participate in  the  distribution of  Securities maybe  entitled  to
indemnification   by   the  Company   against  certain   liabilities,  including
liabilities under the Securities Act.
 
    Underwriters, dealers and agents may engage in transactions with, or perform
services for,  or  be  customers of,  the  Company  in the  ordinary  course  of
business.
 
    If  so indicated  in the Prospectus  Supplement, the  Company will authorize
underwriters or other persons acting as  the Company's agents to solicit  offers
by  certain institutions  to purchase  Securities from  the Company  pursuant to
contracts providing for payment and delivery on a future date. Institutions with
which such contracts may be made include commercial and savings banks, insurance
companies, pension  funds,  investment  companies,  educational  and  charitable
institutions  and others, but in all cases such institutions must be approved by

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Article  Thirteenth of  the Company's Certificate  of Incorporation provides
for the elimination of personal monetary liabilities of directors of the Company
for breaches of certain of their  fiduciary duties to the full extent  permitted
by  Section 102(b)(7)  of the General  Corporation Law of  Delaware (the "GCL").
Section 102(b)(7)  of  the GCL  enables  a  corporation in  its  certificate  of
incorporation  to eliminate  or limit the  personal liability of  members of its
board of directors to the corporation  or its stockholders for monetary  damages
for  violations of a director's fiduciary duty  of care. Such a provision has no
effect on  the availability  of equitable  remedies, such  as an  injunction  or
rescission,  for breach  of fiduciary duty.  In addition, no  such provision may
eliminate or  limit  the liability  of  a director  for  breaching his  duty  of
loyalty,  failing to  act in good  faith, engaging in  intentional misconduct or
knowingly violating the law, paying an unlawful dividend or approving an illegal
stock repurchase, or obtaining an improper personal benefit.
 
    Article VIII of the  Company's By-Laws provides  that directors and  certain
other personnel of the Company shall be indemnified against expenses and certain
other  liabilities arising  out of legal  actions brought  or threatened against
them  for  their  conduct  on  behalf   of  the  Company,  subject  to   certain
qualifications  and provided that each such person  acted in good faith and in a
manner that such person reasonably believed was in the Company's best  interest.
The  Company has entered into indemnification  agreements with each director and
certain officers of the Company and  one of its subsidiaries providing that  (a)
the  Company agrees to comply  in all respects with  each and every provision of
Article VIII of  the By-Laws  in effect  on the date  of the  agreement, (b)  no
amendment  to Article VIII or the agreement will eliminate, reduce or affect any
such directors' or  officers' rights under  Article VIII or  the agreement  with
respect  to indemnification,  and (c)  no legal action  shall be  brought and no
cause of action shall  be asserted by  or on behalf of  the Company against  the
indemnified  party after the expiration of two years from the date of accrual of
such cause of action.
 
    The Company  maintains directors,  and officers,  liability insurance  which
insures  against liabilities that directors or officers of the Company may incur
in such capacities.

ITEM 17.  UNDERTAKINGS.
 
    The Company hereby undertakes:
 
    (1)  To file, during any  period in which offers or  sales are being made, a
post-effective amendment to this Registration Statement:
 
        (i)   To include  any prospectus  required by  Section 10(a)(3)  of  the
    Securities Act of 1933;
 
        (ii)  To reflect in the prospectus any facts or events arising after the
    effective  date  of   the  registration  statement   (or  the  most   recent
    post-effective  amendment thereof) which, individually  or in the aggregate,
    represent  a  fundamental  change  in  the  information  set  forth  in  the
    registration  statement.  Notwithstanding  the  foregoing,  any  increase or
    decrease in  volume of  securities offered  (if the  total dollar  value  of
    securities  offered  would not  exceed that  which  was registered)  and any
    deviation from the low or high  end of the estimated maximum offering  range
    may  be  reflected  in the  form  of  prospectus filed  with  the Commission
    pursuant to Rule  424(b) if,  in the aggregate,  the changes  in volume  and
    price  represent no more than a 20% change in the maximum aggregate offering
    price set  forth in  the  "Calculation of  Registration  Fee" table  in  the
    effective registration statement;
 
                                      II-2
<PAGE>
        (iii)  To include any  material information with respect  to the plan of
    distribution not previously disclosed in  the Registration Statement or  any
    material change to such information in the Registration Statement;
 
PROVIDED,  HOWEVER,  that paragraphs  (1)(i)  and (1)(ii)  do  not apply  if the
Registration Statement  is  on Form  S-3  and  the information  required  to  be
included  in  a post-effective  amendment by  those  paragraphs is  contained in
periodic reports  filed with  or  furnished to  the  Commission by  the  Company
pursuant  to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the Registration Statement.
 
    (2) That, for the purpose of determining any liability under the  Securities
Act  of 1933,  each such post-effective  amendment shall  be deemed to  be a new
registration statement  relating  to the  securities  offered therein,  and  the
offering  of such securities at that time shall be deemed to be the initial BONA
FIDE offering thereof.
 
    (3) To remove from registration by  means of a post-effective amendment  any
of the Securities being registered which remain unsold at the termination of the
offering.
 
    The  Company  hereby  undertakes  that,  for  purposes  of  determining  any
liability under the Securities Act of 1933, each filing of the Company's  annual
report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934
that is incorporated by reference in this Registration Statement shall be deemed
to  be a new registration statement relating  to the securities therein, and the
offering of such securities at that time shall be deemed to be the initial  BONA
FIDE offering thereof.
 
    Insofar  as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to  directors, officers and controlling persons of  the
Company  pursuant to the provisions referred to  an Item 15 of this Registration
Statement, or otherwise, the Company has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act  and is, therefore, unenforceable.  In the event that  a
claim  for indemnification against  such liabilities (other  than the payment by
the Company of expenses incurred or  paid by a director, officer or  controlling
person  of  the  Company  in  the successful  defense  of  any  action,  suit or
proceeding) is  asserted by  such  director, officer  or controlling  person  in
connection with the Securities being registered, the Company will, unless in the
opinion  of its  counsel the matter  has been settled  by controlling precedent,
submit to  a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

                             UNDERWRITING AGREEMENT

                                                                    July  , 1996

GOLDMAN, SACHS & CO.
85 BROAD STREET
NEW YORK, NEW YORK 10004


Dear Sirs:

     From time to time UNUM Corporation, a Delaware corporation (the "Company"),
proposes to enter into one or more Pricing Agreements (each a "Pricing
Agreement") in the form of Annex I hereto, with such additions and deletions as
the parties thereto may determine, and, subject to the terms and conditions
stated herein and therein, to issue and sell to the firms named in Schedule I to
the applicable Pricing Agreement (such firms constituting the "Underwriters"
with respect to such Pricing Agreement and the securities specified therein)
certain [shares] of its [debt securities] [[common] [preferred] stock]
[warrants] (the "Securities") specified in Schedule II to such Pricing Agreement
(with respect to such Pricing Agreement, the "Firm Securities" and together with
any Optional Securities, as defined below, the "Designated Securities"), less
the [principal amount] [number] of Designated Securities covered by Delayed
Delivery Contracts, if any, as provided in Section 3 hereof and as may be
specified in Schedule II to such Pricing Agreement (with respect to such Pricing
Agreement, any Designated Securities to be covered by Delayed Delivery Contracts
being herein sometimes referred to as "Contract Securities" and the Designated
Securities to be purchased by the Underwriters (after giving effect to the
deduction, if any, for Contract Securities) being herein sometimes referred to
as "Underwriters' Securities").

     The terms and rights of any particular issuance of Designated Securities
shall be as specified in the Pricing Agreement relating thereto [IF DEBT
SECURITIES--and in or pursuant to the indenture (the "Indenture") identified in
such Pricing Agreement] [IF PREFERRED STOCK--and in or pursuant to the
resolution or resolutions of the board of directors of the Company or a

<PAGE>

identified in such Pricing Agreement] [IF WARRANTS--and in or pursuant to the
Warrant Agreement identified in such Pricing Agreement].

     1.   Particular sales of Designated Securities may be made from time to
time to the Underwriters of such Securities, for whom the firms designated as
representatives of the Underwriters of such Securities in the Pricing Agreement
relating thereto will act as representatives (the "Representatives"). The term
"Representatives" also refers to a single firm acting as sole representative of
the Underwriters and to Underwriters who act without any firm being designated
as their representative. This Underwriting Agreement shall not be construed as
an obligation of the Company to sell any of the Securities or as an obligation
of any of the Underwriters to purchase the Securities. The obligation of the
Company to issue and sell any of the Securities and the obligation of any of the
Underwriters to purchase any of the Securities shall be evidenced by the Pricing
Agreement with respect to the Designated Securities specified therein. Each
Pricing Agreement with respect to Designated Securities shall be substantially
in the form attached hereto as Annex I and shall specify the names of the
Underwriters of such Designated Securities, the names of the Representatives, if
any, of such Underwriters, the [INSERT IF DEBT SECURITIES--principal amount of]
[INSERT IF COMMON OR PREFERRED STOCK--aggregate number of] Firm Securities and
the [INSERT IF DEBT SECURITIES--principal amount of] [INSERT IF COMMON OR
PREFERRED STOCK--maximum number of] Optional Securities, if any, to be purchased
by each Underwriter and the commission, if any, payable to the Underwriter with
respect thereto, whether any of such Designated Securities shall be covered by
Delayed Delivery Contracts (as defined in Section 3 hereof), the purchase price
to the Underwriters of such Designated Securities, the nature of the funds to be
delivered by the Underwriters [and][ , ] the initial public offering price or
the manner of determining such price, if any [IF DEBT SECURITIES, INSERT--,
including, interest rates, if any, maturity, whether such Securities will be
convertible at the option of the holder thereof into [shares of the Company's
Common Stock, par value $.10 per share (the "Common Stock")] [INSERT DESCRIPTION
OF OTHER SECURITIES INTO WHICH CONVERTIBLE], any conversion rates or price(s),
whether warrants shall be attached to such Debt Securities, any redemption
provisions and any sinking fund requirements] [IF PREFERRED STOCK, INSERT--,
annual dividend rates, sinking fund provisions, if any, whether such Securities
will be convertible at the option of the holder thereof into shares of the
Company's Common Stock]. A Pricing Agreement shall be in the form of an executed
writing (which may be in counterparts, and may be evidenced by an exchange of
telegraphic communications or any other rapid transmission device designed to
produce a written record of communications transmitted). The obligations of the
Underwriters under this Agreement and each Pricing Agreement shall be several
and not joint.

Underwriters that:

          (a)  Two registration statements on Form S-3 (No. 33-69132 and No.
     333-       ), including a prospectus for use in connection with the
     Designated Securities pursuant to Rule 429 under the Securities Act of
     1933, as amended (the "Act"), in respect of the Securities [and any [shares
     of Common Stock] [INSERT OTHER SECURITIES INTO WHICH CONVERTIBLE OR ARE
     EXCHANGEABLE FOR] issuable upon conversion or exercise of or exchange of
     the Securities] have been filed with the Securities and Exchange Commission
     (the "Commission"); such registration statements and any post-effective
     amendment thereto, each in the form heretofore delivered or to be delivered
     to the Representatives for each of the other Underwriters and, excluding
     exhibits to such registration statements, but including all documents
     incorporated by reference in the prospectuses contained therein, have been
     declared effective by the Commission in such form; other than a
     registration statement, if any, increasing the size of the offering (a
     "Rule 462(b) Registration Statement"), filed pursuant to Rule 462(b) under
     the Act, which became effective upon filing, no other document with respect
     to such registration statements or document incorporated by reference
     therein has heretofore been filed or transmitted for filing with the
     Commission; such prospectus included for use in connection with the
     Securities pursuant to Rule 429 under the Act meets the requirements of the
     Act and the rules and regulations thereunder for use of such prospectus in
     connection with the Securities; and no stop order suspending the

     threatened by the Commission. Any preliminary prospectus included in either
     of such registration statements or filed with the Commission pursuant to
     Rule 424(a) of the rules and regulations of the Commission under the Act,
     is hereinafter called a "Preliminary Prospectus;" the various parts of such
     registration statements and the Rule 462(b) Registration Statement, if any,
     including all exhibits thereto and the documents incorporated by reference
     in the prospectuses contained in such registration statements and the Rule
     462(b) Registration Statement, if any, at the time such part of such
     registration statements or such part of the Rule 462(b) Registration
     Statement, if any, became or hereafter becomes effective but excluding Form
     T-1, each as amended at the time such part of the registration statements
     or such part of the Rule 462(b) Registration Statement, if any, became
     effective and at the time each incorporated document was filed with the
     Commission is hereinafter called the "Registration Statement;" the
     prospectus relating to the Securities, in the form in which it has most
     recently been filed, or transmitted for filing, with the Commission on or
     prior to the date of this Agreement, is


                                        3

     hereinafter called the "Prospectus;" any reference herein to any
     Preliminary Prospectus or the Prospectus shall be deemed to refer to and
     include the documents incorporated by reference therein pursuant to the

     Prospectus or Prospectus, as the case may be; any reference to any
     amendment or supplement to any Preliminary Prospectus or the Prospectus
     shall be deemed to refer to and include any documents filed after the date
     of such Preliminary Prospectus or Prospectus, as the case may be, under the
     Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
     incorporated by reference in such Preliminary Prospectus or Prospectus, as
     the case may be; any reference to any amendment to the Registration
     Statement shall be deemed to refer to and include any annual report of the
     Company filed pursuant to Section 13(a) or 15(d) of the Exchange Act after
     the effective date of the Registration Statement that is incorporated by
     reference in the Registration Statement; and any reference to the

     pursuant to Rule 424(b) under the Act in accordance with Section 5(a)
     hereof, including any documents incorporated by reference therein as of the
     date of such filing);

          (b)  The documents incorporated by reference in the Prospectus, when
     they became effective or were filed with the Commission, as the case may
     be, conformed in all material respects to the requirements of the Act or
     the Exchange Act, as applicable, and the rules and regulations of the
     Commission thereunder, and none of such documents contained an untrue
     statement of a material fact or omitted to state a material fact required
     to be stated therein or necessary to make the statements therein not
     misleading; and any further documents so filed and incorporated by
     reference in the Prospectus or any further amendment or supplement thereto,

     be stated therein or necessary to make the statements therein (i) in the
     case of the Registration Statement, not misleading and (ii) in the case of

     proceedings are threatened or contemplated by governmental authorities or
     threatened by others;

          (j)  Coopers & Lybrand L.L.P., who have audited certain financial

     3.   Upon the execution of the Pricing Agreement applicable to any
Designated Securities and authorization by the Representatives of the release of
such Firm Securities, the several Underwriters propose to offer such Firm
Securities for sale upon the terms and conditions set forth in the Prospectus as
amended or supplemented.

     The Company may specify in the Pricing Agreement applicable to any
Designated Securities that the Company thereby grants to the Underwriters the
right (an "Over-allotment Option") to purchase at their election up to [INSERT
IF DEBT SECURITIES--the aggregate principal amount of] [INSERT IF COMMON OR
PREFERRED STOCK OR WARRANTS--the number of], Optional Securities set forth in
such Pricing Agreement, at the terms set forth in the paragraph above, for the
sole purpose of covering over-allotments in the sale of the Firm Securities. Any
such election to purchase Optional Securities may be exercised only by written
notice from the Representatives to the Company, given within a period specified
in the Pricing Agreement, setting forth [INSERT IF DEBT SECURITIES--the
aggregate principal amount of] [INSERT IF COMMON OR PREFERRED STOCK OR WARRANTS-
- -the aggregate number of], Optional Securities to be

purchased and the date on which such Optional Securities are to be delivered, as
determined by the Representatives but in no event earlier than the First Time of
Delivery (as defined in Section 4 hereof) or, unless the Representatives and the
Company otherwise agree in writing, earlier than or later than the respective
number of business days after the date of such notice set forth in such Pricing
Agreement.

     The [INSERT IF DEBT SECURITIES--aggregate principal amount of] [INSERT IF
COMMON OR PREFERRED STOCK OR WARRANTS--number of] Optional Securities to be
added to the number of Firm Securities to be purchased by each Underwriter as
set forth in Schedule I to the Pricing Agreement applicable to such Designated
Securities shall be, in each case, [INSERT IF DEBT SECURITIES--the aggregate
principal amount of] [INSERT IF COMMON OR PREFERRED STOCK OR WARRANTS--the
number of] Optional Securities which the Company has been advised by the
Representatives have been attributed to such Underwriter, provided that, if the
Company has not been so advised, [INSERT IF DEBT SECURITIES--the aggregate
principal amount of] [INSERT IF COMMON OR PREFERRED STOCK OR WARRANTS--the
number of] Optional Securities to be so added shall be, in each case, that
proportion of Optional Securities which [INSERT IF DEBT SECURITIES--the
aggregate principal amount of] [INSERT IF COMMON OR PREFERRED STOCK OR WARRANTS-
- -the number of] Firm Securities to be purchased by such Underwriter under such
Pricing Agreement bears to the aggregate [INSERT IF DEBT SECURITIES--aggregate
principal amount of] [INSERT IF COMMON OR PREFERRED STOCK OR WARRANTS--number
of] of Firm Securities [(rounded as the Representatives may determine to the
nearest 100 shares)]. The total [INSERT IF DEBT SECURITIES--aggregate principal
amount of] [INSERT IF COMMON OR PREFERRED STOCK OR WARRANTS--number of]
Designated Securities to be purchased by all the Underwriters pursuant to such
Pricing Agreement shall be the aggregate [INSERT IF DEBT SECURITIES--aggregate
principal amount of] [INSERT IF COMMON OR PREFERRED STOCK OR WARRANTS--number
of] Firm Securities set forth in Schedule I to such Pricing Agreement plus the
aggregate number of the Optional Securities which the Underwriters elect to
purchase.

     The Company may specify in Schedule II to the Pricing Agreement applicable
to any Designated Securities that the Underwriters are authorized to solicit
offers to purchase Designated Securities from the Company pursuant to delayed
delivery contracts (herein called "Delayed Delivery Contracts"), substantially
in the form of Annex III attached hereto but with such changes therein as the
Representatives and the Company may authorize or approve. If so specified, the
Underwriters will endeavor to make such arrangements, and as compensation
therefor the Company will pay to the Representatives, for the accounts of the
Underwriters, at the Time of Delivery (as defined in Section 4 hereof), such
commission, if any, as may be set forth in such Pricing Agreement. Delayed
Delivery Contracts, if any, are to be with investors of the types described in
the Prospectus and subject to other conditions therein


                                       11

set forth. The Underwriters will not have any responsibility with respect to the
validity or performance of any Delayed Delivery Contracts.

     The [INSERT IF DEBT SECURITIES--aggregate principal amount][INSERT IF
COMMON OR PREFERRED STOCK OR WARRANTS--number] of Contract Securities to be
deducted from the [INSERT IF DEBT SECURITIES--aggregate principal amount]
[INSERT IF COMMON OR PREFERRED STOCK OR WARRANTS--number] of Designated
Securities to be purchased by each Underwriter as set forth in Schedule I to the
Pricing Agreement applicable to such Designated Securities shall be, in each
case, the [INSERT IF DEBT SECURITIES--aggregate principal amount] [INSERT IF
COMMON OR PREFERRED STOCK OR WARRANTS--number] of Contract Securities which the
Company has been advised by the Representatives have been attributed to such
Underwriter, provided that, if the Company has not been so advised, the amount
of Contract Securities to be so deducted shall be, in each case, that proportion
of Contract Securities which the [INSERT IF DEBT SECURITIES--aggregate principal
amount] [INSERT IF COMMON OR PREFERRED STOCK OR WARRANTS--number] of Designated
Securities to be purchased by such Underwriter under such Pricing Agreement
bears to the total [INSERT IF DEBT SECURITIES--aggregate principal amount]
[INSERT IF COMMON OR PREFERRED STOCK OR WARRANTS--number] of the Designated
Securities (rounded as the Representatives may determine). The total [INSERT IF
DEBT SECURITIES--aggregate principal amount] [INSERT IF COMMON OR PREFERRED
STOCK OR WARRANTS--number] of Underwriters' Securities to be purchased by all
the Underwriters pursuant to such Pricing Agreement shall be the total [INSERT
IF DEBT SECURITIES--aggregate principal amount] [INSERT IF COMMON OR PREFERRED
STOCK OR WARRANTS--number] of Designated Securities set forth in Schedule I to
such Pricing Agreement less the [INSERT IF DEBT SECURITIES--principal amount]
[INSERT IF COMMON OR PREFERRED STOCK OR WARRANTS--number] of the Contract
Securities. The Company will deliver to the Representatives not later than 3:30
p.m., New York City time, on the third business day preceding the Time of

[INSERT IF COMMON OR PREFERRED STOCK OR WARRANTS--number] of Contract
Securities.

such time and date, if not the First Time of Delivery, herein called the "Second
Time of Delivery." Each such time and date for delivery is herein called a "Time

Wednesday, Thursday, and Friday which is not a day on which banking institutions
in New York are generally authorized or obligated by law or executive order to

     Concurrently with the delivery of and payment for the Underwriters'

     any proceeding for any such purpose, or of any request by the Commission
     for the amending or supplementing of the Registration Statement or
     Prospectus or for additional information; and, in the event of the issuance
     of any such stop order or of any such order preventing or suspending the
     use of any prospectus relating to the Securities or suspending any such
     qualification, to use promptly its best efforts to obtain its withdrawal;

          (b)  Promptly from time to time to take such action as the

     any event shall have occurred as a result of which the Prospectus as then
     amended or supplemented would include an untrue statement of a material
     fact or omit to state any material fact necessary in order to make the
     statements therein, in the light of the circumstances under which they were
     made

     Coopers & Lybrand L.L.P. shall have furnished to the Representatives a
     letter, dated the effective date of the Registration Statement or the date
     of the most recent report filed with the Commission containing financial
     statements and incorporated by reference in the Registration Statement, if
     the date of such report is later than such effective date, and a letter
     dated such Time of Delivery, respectively, to the effect set forth in Annex
     II hereto, and with respect to such letter dated such Time of Delivery, as
     to such other matters as the Representatives may reasonably request and in
     form and substance satisfactory to the Representatives;

          (f)  (i) Neither the Company nor any of its subsidiaries shall have
     sustained since the date of the latest audited financial statements
     included or incorporated by reference in the Prospectus as amended or
     supplemented any loss or interference with its business from fire,
     explosion, flood or other calamity, whether or not covered by insurance, or
     from any labor dispute or court or government action, order or decree,
     otherwise than as set forth or contemplated in the Prospectus as amended or
     supplemented, and (ii) since the respective dates as of which information
     is given or incorporated by reference in the Prospectus as amended or
     supplemented there shall not have been any material change in the capital
     stock or long-term debt of the Company or any of its subsidiaries or any
     change, or any development involving a prospective change, in or affecting
     the general affairs, management, financial position, stockholders' equity
     or results of operations of the Company and its subsidiaries considered as
     a whole, otherwise than as set forth or contemplated in the Prospectus as
     amended or supplemented, the effect of which, in any such case described in
     Clause (i) or (ii), is in the judgment of the Representatives so material
     and adverse as to make it impracticable or inadvisable to proceed with the
     public offering or the delivery of the Underwriters' Securities on the
     terms and in the manner contemplated in the Prospectus as amended or
     supplemented;

          (g)  On or after the date of the Pricing Agreement relating to the
     Designated Securities (i) no downgrading shall have occurred in the rating
     accorded the Company's debt securities or preferred stock by any
     "nationally recognized statistical rating organization," as that term is
     defined by the Commission for purposes of Rule 436(g)(2) under the Act and
     (ii) no such organization shall have publicly announced that it has under
     surveillance or review, with possible negative implications, its


                                       30
<PAGE>

     rating of any of the Company's debt securities or preferred stock;

          (h)  On or after the date of the Pricing Agreement relating to the
     Designated Securities there shall not have occurred any of the following:
     (i) a suspension or material limitation in trading in securities generally
     on the New York Stock Exchange; (ii) a general moratorium on commercial
     banking activities in New York declared by either Federal or New York state
     authorities; or (iii) the outbreak or material escalation of hostilities
     involving the United States or the declaration by the United States of a
     national emergency or war, if the effect of any such event specified in
     this Clause (iii) in the judgment of the Representatives makes it
     impracticable or inadvisable to proceed with the public offering or the
     delivery of the Firm Securities or the Optional Securities, or both, on the
     terms and in the manner contemplated by the Prospectus as amended or
     supplemented; and

          (i)  The Company shall have furnished or caused to be furnished to the
     Representatives at each Time of Delivery for the Designated Securities a
     certificate or certificates of officers of the Company satisfactory to the
     Representatives as to the accuracy of the representations and warranties of
     the Company herein at and as of each Time of Delivery, as to the
     performance by the Company of all of its obligations hereunder to be
     performed at or prior to each Time of Delivery, as to the matters set forth
     in subsections (a) and (e) of this Section and as to such other matters as
     the Representatives may reasonably request.

     8.   (a) The Company will indemnify and hold harmless each Underwriter
against any losses, claims, damages or liabilities, joint or several, to which
such Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus as amended or
supplemented and any other prospectus relating to the Securities, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein (i) in the case of the
Registration Statement, not misleading and (ii) in the case of the Prospectus,
in the light of the circumstances under which they were made, not misleading,
and will reimburse each Underwriter for any legal or other expenses reasonably
incurred by such Underwriter in connection with investigating or defending any
such action or claim as such expenses are incurred; provided, however, that the
Company shall not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon an


                                       31
<PAGE>

untrue statement or alleged untrue statement or omission or alleged omission
made in any Preliminary Prospectus, any preliminary prospectus supplement, the
Registration Statement, the Prospectus as amended or supplemented and any other
prospectus relating to the Securities, or any such amendment or supplement in
reliance upon and in conformity with written information furnished to the
Company by any Underwriter of Designated Securities through the Representatives
expressly for use in the Prospectus as amended or supplemented relating to such
Securities; and provided, further, that the Company shall not be liable to any
Underwriter under the indemnity agreement in this subsection (a) with respect to
any Preliminary Prospectus to the extent that any such loss, claim, damage or
liability of such Underwriter results from the fact such Underwriter sold
Securities to a person to whom there was not sent or given, at or prior to the
written confirmation of such sale, a copy of the Prospectus (excluding documents
incorporated by reference) or of the Prospectus as then amended or supplemented
(excluding documents incorporated by reference) in any case where such delivery
is required by the Act if the Company has previously furnished copies thereof to
such Underwriter and the loss, claim, damage or liability of such Underwriter
results from an untrue statement or omission of a material fact contained in the
Preliminary Prospectus which was corrected in the Prospectus (or the Prospectus
as amended or supplemented).

     (b)  Each Underwriter will indemnify and hold harmless the Company against
any losses, claims, damages or liabilities to which the Company may become
subject, under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, any preliminary prospectus supplement, the Registration
Statement, the Prospectus as amended or supplemented and any other prospectus
relating to the Securities, or any amendment or supplement thereto, or arise out
of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein (i) in the case of the Registration Statement, not misleading and (ii)
in the case of any Prospectus, in the light of the circumstances under which
they were made, not misleading, in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was made in any Preliminary Prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus as amended or
supplemented and any other prospectus relating to the Securities, or any such
amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by such Underwriter through the
Representatives expressly for use therein; and will reimburse the Company for
any legal or other expenses reasonably incurred by the Company in connection
with investigating or defending any such action or claim as such expenses are
incurred.


                                       32

     (c)  Promptly after receipt by an indemnified party under subsection (a) or
(b) above of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under such subsection, notify the indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party shall
not relieve it from any liability which it may have to any indemnified party
otherwise than under such subsection. In case any such action shall be brought
against any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party (who shall not, except with the
consent of the indemnified party, be counsel to the indemnifying party), and,
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party under such subsection for any legal expenses of
other counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable
costs of investigation.

     (d)  If the indemnification provided for in this Section 8 is unavailable
to or insufficient to hold harmless an indemnified party under subsection (a) or
(b) above in respect of any losses, claims, damages or liabilities (or actions
in respect thereof) referred to therein, then each indemnifying party shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities (or actions in respect thereof)
in such proportion as is appropriate to reflect the relative benefits received
by the Company on the one hand and the Underwriters of the Designated Securities
on the other from the offering of the Designated Securities to which such loss,
claim, damage or liability (or action in respect thereof) relates. If, however,
the allocation provided by the immediately preceding sentence is not permitted
by applicable law or if the indemnified party failed to give the notice required
under subsection (c) above, then each indemnifying party shall contribute to
such amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company on the one hand and the Underwriters of the Designated
Securities on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities (or actions in respect
thereof), as well as any other relevant equitable considerations. The relative
benefits received by the Company on the one hand and such Underwriters on the
other shall be deemed to be in the same proportion as the total net proceeds
from such offering (before deducting expenses) received by the Company bear to
the total underwriting discounts and commissions received by such Underwriters.
The relative fault shall be determined by reference to, among other things,
whether


                                       33
<PAGE>

the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company on the one hand or such Underwriters on the other and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Company and the Underwriters agree that
it would not be just and equitable if contribution pursuant to this subsection
(d) were determined by pro rata allocation (even if the Underwriters were
treated as one entity for such purpose) or by any other method of allocation
which does not take account of the equitable considerations referred to above in
this subsection (d). The amount paid or payable by an indemnified party as a
result of the losses, claims, damages or liabilities (or actions in respect
thereof) referred to above in this subsection (d) shall be deemed to include any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this subsection (d), no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the applicable Designated Securities underwritten by it and
distributed to the public were offered to the public exceeds the amount of any
damages which such Underwriter has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The obligations of the Underwriters
of Designated Securities in this subsection (d) to contribute are several in
proportion to their respective underwriting obligations with respect to such
Securities and not joint.

     (e)  The obligations of the Company under this Section 8 shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each person, if any, who controls any
Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section 8 shall be in addition to any liability which
the respective Underwriters may otherwise have and shall extend, upon the same
terms and conditions, to each officer and director of the Company and to each
person, if any, who controls the Company within the meaning of the Act.

     9.   (a) If any Underwriter shall default in its obligation to purchase the
Firm Securities or Optional Securities which it has agreed to purchase under the
Pricing Agreement relating to such Firm Securities or Optional Securities, the
Representatives may in their discretion arrange for themselves or another party
or other parties to purchase such Underwriters' Securities on the terms
contained herein. If within thirty-six hours after such default by any
Underwriter the Representatives do not arrange for the purchase of such Firm
Securities or Optional Securities, then the Company


                                       34
<PAGE>

shall be entitled to a further period of thirty-six hours within which to
procure another party or other parties satisfactory to the Representatives to
purchase such Firm Securities or Optional Securities on such terms. In the event
that, within the respective prescribed period, the Representatives notify the
Company that they have so arranged for the purchase of such Firm Securities or
Optional Securities, or the Company notifies the Representatives that it has so
arranged for the purchase of such Firm Securities or Optional Securities, the
Representatives or the Company shall have the right to postpone the Time of
Delivery for such Firm Securities or Optional Securities for a period of not
more than seven days, in order to effect whatever changes may thereby be made
necessary in the Registration Statement or the Prospectus as amended or
supplemented, or in any other documents or arrangements, and the Company agrees
to file promptly any amendments or supplements to the Registration Statement or
the Prospectus which in the opinion of the Representatives may thereby be made
necessary. The term "Underwriter" as used in this Agreement shall include any
person substituted under this Section with like effect as if such person had
originally been a party to the Pricing Agreement with respect to such Designated
Securities.

     (b)  If, after giving effect to any arrangements for the purchase of the
Firm Securities or Optional Securities, as the case may be, of a defaulting
Underwriter or Underwriters by the Representatives and the Company as provided
in subsection (a) above, the aggregate [number] [principal amount] of such Firm
Securities or Optional Securities, as the case may be, which remains unpurchased
does not exceed one-eleventh of the aggregate [principal amount] of the Firm
Securities or Optional Securities, as the case may be, then the Company shall
have the right to require each non-defaulting Underwriter to purchase the
[number] [principal amount] of Firm Securities or Optional Securities, as the
case may be, which such Underwriter agreed to purchase under the Pricing
Agreement relating to such Designated Securities and, in addition, to require
each non-defaulting Underwriter to purchase its pro rata share (based on the
[number] [principal amount] of Firm Securities or Optional Securities, as the
case may be, which such Underwriter agreed to purchase under such Pricing
Agreement) of the Firm Securities or Optional Securities, as the case may be, of
such defaulting Underwriter or Underwriters for which such arrangements have not
been made; but nothing herein shall relieve a defaulting Underwriter from
liability for its default.

     (c)  If, after giving effect to any arrangements for the purchase of the
Firm Securities or Optional Securities, as the case may be, of a defaulting
Underwriter or Underwriters by the Representatives and the Company as provided
in subsection (a) above, the aggregate [number] [principal amount] of Firm
Securities or Optional Securities, as the case may be, which remains unpurchased
exceeds one-eleventh of the aggregate [number] [principal amount] of the Firm
Securities or Optional Securities,


                                       35
<PAGE>

as the case may be, as referred to in subsection (b) above, or if the Company
shall not exercise the right described in subsection (b) above to require
non-defaulting Underwriters to purchase Firm Securities or Optional Securities,
as the case may be, of a defaulting Underwriter or Underwriters, then the
Pricing Agreement relating to such Designated Securities shall thereupon
terminate, without liability on the part of any non-defaulting Underwriter or
the Company, except for the expenses to be borne by the Company and the
Underwriters as provided in Section 6 hereof and the indemnity and contribution
agreements in Section 8 hereof; but nothing herein shall relieve a defaulting
Underwriter from liability for its default.

     10.  The respective indemnities, agreements, representations, warranties
and other statements of the Company and the several Underwriters, as set forth
in this Agreement or made by or on behalf of them, respectively, pursuant to
this Agreement, shall remain in full force and effect, regardless of any
investigation (or any statement as to the results thereof) made by or on behalf
of any Underwriter or any controlling person of any Underwriter, or the Company,
or any officer or director or controlling person of the Company, and shall
survive delivery of and payment for the Securities.

     11.  If any Pricing Agreement or Over-allotment Option shall be terminated
pursuant to Section 9 hereof, the Company shall not then be under any liability
to any Underwriter with respect to the Firm Securities or Optional Securities
covered by such Pricing Agreement except as provided in Section 6 and Section 8
hereof; but, if for any other reason Designated Securities are not delivered by
or on behalf of the Company as provided herein, the Company will reimburse the
Underwriters through the Representatives for all out-of-pocket expenses approved
in writing by the Representatives, including fees and disbursements of counsel,
reasonably incurred by the Underwriters in making preparations for the purchase,
sale and delivery of such Designated Securities, but the Company shall then be
under no further liability to any Underwriter with respect to such Designated
Securities except as provided in Section 6 and Section 8 hereof.

     12.  In all dealings hereunder, the Representatives of the Underwriters of
Designated Securities shall act on behalf of each of such Underwriters, and the
parties hereto shall be entitled to act and rely upon any statement, request,
notice or agreement on behalf of any Underwriter made or given by such
Representatives jointly or by such of the Representatives, if any, as may be
designated for such purpose in the Pricing Agreement.

     All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to the address of the Representatives as set forth in the
Pricing Agreement; and if to


                                       36
<PAGE>

the Company shall be delivered or sent by mail, telex or facsimile transmission
to the address of the Company set forth in the Registration Statement;
Attention: Secretary; provided, however, that any notice to an Underwriter
pursuant to Section 8(c) hereof shall be delivered or sent by mail, telex or
facsimile transmission to such Underwriter at its address set forth in its
Underwriters' Questionnaire, or telex constituting such Questionnaire, which
address will be supplied to the Company by the Representatives upon request. Any
such statements, requests, notices or agreements shall take effect upon receipt
thereof.

     13.  This Agreement and each Pricing Agreement shall be binding upon, and
inure solely to the benefit of, the Underwriters, the Company and, to the extent
provided in Section 8 and Section 10 hereof, the officers and directors of the
Company and each person who controls the Company or any Underwriter, and their
respective heirs, executors, administrators, successors and assigns, and no
other person shall acquire or have any right under or by virtue of this
Agreement or any such Pricing Agreement. No purchaser of any of the Securities

CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

     16.  This Agreement and each Pricing Agreement may be executed by any one

     Pursuant to Section 7(e) of the Underwriting Agreement, the accountants
shall furnish letters to the Underwriters to the effect that:

          (i)  They are independent certified public accountants with respect to
     the Company and its subsidiaries within the meaning of the Act and the
     applicable published rules and regulations thereunder;

         (ii)  In their opinion, the financial statements and any supplementary
     financial information and schedules audited (and, if applicable,
     prospective financial statements and/or pro forma financial information
     examined) by them and included or incorporated by reference in the
     Registration Statement or the Prospectus comply as to form in all material
     respects with the applicable accounting requirements of the Act or the
     Exchange Act, as applicable, and the related published rules and
     regulations thereunder; and, if applicable, they have made a review in
     accordance with standards established by the American Institute of
     Certified Public Accountants of the consolidated interim financial
     statements, selected financial data, pro forma financial information,
     prospective financial statements and/or condensed financial statements
     derived from audited financial statements of the Company for the periods
     specified in such letter, as indicated in their reports thereon, copies of
     which have been furnished to the representatives of the Underwriters (the
     "Representatives");

        (iii)  The unaudited selected financial information with respect to the
     consolidated results of operations and financial position of the Company
     for the five most recent fiscal years included in the Prospectus and
     included or incorporated by reference in Item 6 of the Company's Annual
     Report on Form 10-K for the most recent fiscal year agrees with the
     corresponding amounts (after restatement where applicable) in the audited
     consolidated financial statements for five such fiscal years which were
     included or incorporated by reference in the Company's Annual Reports on
     Form 10-K for such fiscal years;

         (iv)  On the basis of limited procedures, not constituting an audit in
     accordance with generally accepted auditing standards, consisting of a
     reading of the unaudited financial statements and other information
     referred to below, a reading of the latest available interim financial
     statements of the Company and its subsidiaries, inspection of the minute
     books of the Company and its subsidiaries since the date of the latest
     audited financial statements included or incorporated by reference in the
     Prospectus, inquiries of officials of the Company and its subsidiaries
     responsible for financial and accounting matters and such other inquiries
     and procedures as may be specified in
<PAGE>

     such letter, nothing came to their attention that caused them to believe
     that:

               (A) the unaudited condensed consolidated statements of income,
          consolidated balance sheets and consolidated statements of cash flows
          included or incorporated by reference in the Company's Quarterly
          Reports on Form 10-Q incorporated by reference in the Prospectus do
          not comply as to form in all material respects with the applicable
          accounting requirements of the Exchange Act as it applies to Form 10-Q
          and the related published rules and regulations thereunder or are not
          in conformity with generally accepted accounting principles applied on
          a basis substantially consistent with the basis for the audited
          consolidated statements of income, consolidated balance sheets and
          consolidated statements of cash flows included or incorporated by
          reference in the Company's Annual Report on Form 10-K for the most
          recent fiscal year;

               (B) any other unaudited income statement data and balance sheet
          items included in the Prospectus do not agree with the corresponding
          items in the unaudited consolidated financial statements from which
          such data and items were derived, and any such unaudited data and
          items were not determined on a basis substantially consistent with the
          basis for the corresponding amounts in the audited consolidated
          financial statements included or incorporated by reference in the
          Company's Annual Report on Form 10-K for the most recent fiscal year;

               (C) the unaudited financial statements which were not included in
          the Prospectus but from which were derived the unaudited condensed
          financial statements referred to in clause (A) above and any unaudited
          income statement data and balance sheet items included in the
          Prospectus and referred to in Clause (B) above were not determined on
          a basis substantially consistent with the basis for the audited
          financial statements included or incorporated by reference in the
          Company's Annual Report on Form 10-K for the most recent fiscal year;

               (D) any unaudited pro forma consolidated condensed financial
          statements included or incorporated by reference in the Prospectus do
          not comply as to form in all material respects with the applicable
          accounting requirements of the Act and the published rules and
          regulations thereunder or the pro forma adjustments have not been
          properly applied to the historical amounts in the compilation of those
          statements;

               (E) as of a specified date not more than five days prior to the
          date of such letter, there have been any changes in


                                        2
<PAGE>

          the consolidated capital stock (other than issuances of capital stock
          upon exercise of options and stock appreciation rights, upon earn-outs
          of performance shares and upon conversions of convertible securities,
          in each case which were outstanding on the date of the latest balance
          sheet included or incorporated by reference in the Prospectus) or any
          increase in the consolidated long-term debt of the Company and its
          subsidiaries, or any decreases in consolidated net assets or other
          items specified by the Representatives, or any increases in any items
          specified by the Representatives, in each case as compared with
          amounts shown in the latest balance sheet included or incorporated by
          reference in the Prospectus, except in each case for changes,
          increases or decreases which the Prospectus discloses have occurred or
          may occur or which are described in such letter; and

               (F) for the period from the date of the latest financial
          statements included or incorporated by reference in the Prospectus to
          the specified date referred to in Clause (E) above there were any
          decreases in consolidated net revenues or any material decrease in
          operating profit or any material decrease in the total or per share
          amounts of consolidated net income or other items specified by the
          Representatives, or any increases in any items specified by the
          Representatives, in each case as compared with the comparable period
          of the preceding year and with any other period of corresponding
          length specified by the Representatives, except in each case for
          increases or decreases which the Prospectus discloses have occurred or
          may occur or which are described in such letter; and

          (v)  In addition to the audit referred to in their report(s) included
     or incorporated by reference in the Prospectus and the limited procedures,
     inspection of minute books, inquiries and other procedures referred to in
     paragraphs (iii) and (iv) above, they have carried out certain specified
     procedures, not constituting an audit in accordance with generally accepted
     auditing standards, with respect to certain amounts, percentages and
     financial information specified by the Representatives which are derived
     from the general accounting records of the Company and its subsidiaries,
     which appear in the Prospectus (excluding documents incorporated by
     reference), or in Part II of, or in exhibits and schedules to, the
     Registration Statement specified by the Representatives or in documents
     incorporated by reference in the Prospectus specified by the
     Representatives, and have compared certain of such amounts, percentages and
     financial information with the accounting records of the Company and its
     subsidiaries and have found them to be in agreement.

     All references in this Annex II to the Prospectus shall be deemed to refer
to the Prospectus (including the documents


                                        3

                          ]

Dear Sirs:

          UNUM Corporation, a Delaware corporation (the "Company"), proposes to
issue and sell from time to time its Medium-Term Notes, Series C (the
"Securities") at an aggregate initial public offering price of up to
$250,000,000 and agrees with each of you (individually, an "Agent", and
collectively, the "Agents") as set forth in this Agreement.

          Subject to the terms and conditions stated herein and to the
reservation by the Company of the right to sell Securities directly on its own
behalf, the Company hereby (i) appoints each Agent as an agent of the Company
for the purpose of soliciting and receiving offers to purchase Securities from
the Company pursuant to Section 2(a) hereof and (ii) agrees that, except as
otherwise contemplated herein, whenever it determines to sell Securities
directly to any Agent as principal, it will enter into a separate agreement
(each a "Terms Agreement") which may be either (i) a written agreement,
substantially in the form of Annex I hereto, or (ii) an oral agreement between
such Agent and the Company confirmed in writing by such Agent to the Company,
relating to such sale in accordance with Section 2(b) hereof.

          The Securities will be issued under the Indenture, dated as of
September 15, 1990 (the "Indenture"), between the Company and The Chase
Manhattan Bank (National Association), as Trustee (the "Trustee").  The
Securities
<PAGE>

shall have the maturity ranges, interest rates, if any, redemption provisions
and other terms set forth in the Prospectus referred to below as it may be
amended or supplemented from time to time.  The Securities will be issued, and
the terms and rights of holders thereof established, from time to time by the
Company in accordance with the Indenture.

          1.  The Company represents and warrants to, and agrees with, each
Agent that:

          (a)  Two registration statements (File Nos. 33-69132 and 333- _____),
including a prospectus for use in connection with the Securities pursuant to
Rule 429 under the Securities Act of 1933, as amended (the "Act"), in respect of
$500,000,000 aggregate amount of securities of the Company, including the
Securities, have been filed with the Securities and Exchange Commission (the
"Commission"); such registration statements and any post-effective amendment
thereto, each in the form heretofore delivered or to be delivered to such Agent,
excluding exhibits to such registration statements, but including all documents
incorporated by reference therein have been declared effective by the Commission
in such form; no other document with respect to such registration statements
(other than a document incorporated by reference therein) has heretofore been
filed or transmitted for filing with the Commission; such prospectus included
for use in connection with the Securities pursuant to Rule 429 under the Act and
the rules and regulations thereunder for use of such prospectus in connection
with the Securities; and no stop order suspending the effectiveness of either of
such registration statements has been issued and no proceeding for that purpose
has been instituted or threatened by the Commission (any preliminary prospectus
included in either of such registration statements or filed with the Commission
pursuant to Rule 424(a) of the rules and regulations of the Commission under the
Act, being hereinafter called a "Preliminary Prospectus"; the various parts of
such registration statements, including all exhibits thereto and the documents
incorporated by reference in the prospectuses contained in such registration
statements at the time such part of such registration statements became
effective but excluding Form T-1, each such part as amended at the time such
part became effective, being hereinafter collectively called the "Registration
Statement"; the prospectus (including the prospectus supplement) relating to the
Securities, in the form in which it has most recently been filed, or transmitted
for filing, with the Commission on or prior to the date of this Agreement being
hereinafter called the "Prospectus"; any reference herein to any Preliminary
Prospectus or the


                                       -2-
<PAGE>

Prospectus shall be deemed to refer to and include the documents incorporated by
reference therein pursuant to the applicable form under the Act, as of the date
of such Preliminary Prospectus or Prospectus, as the case may be; any reference
to any amendment or supplement to any Preliminary Prospectus or the Prospectus,
including any supplement to the Prospectus that sets forth only the terms of the
particular issue of the Securities (a "Pricing Supplement"), shall be deemed to
refer to and include any documents filed after the date of such Preliminary
Prospectus or Prospectus, as the case may be, under the Securities Exchange Act
of 1934, as amended (the "Exchange Act"), and incorporated by reference in such
Preliminary Prospectus or the Prospectus, as the case may be; any reference to
any amendment to the Registration Statement shall be deemed to include any
report of the Company filed pursuant to the Exchange Act after the effective
date of the Registration Statement that is incorporated by reference in the
Registration Statement; and any reference to the Prospectus as amended or
supplemented shall be deemed to refer to and include the Prospectus as amended
or supplemented (including by the applicable Pricing Supplement filed in
accordance with Section 4(a) hereof) in relation to Securities sold pursuant to
this Agreement, in the form in which it is filed with the Commission pursuant to
Rule 424(b) under the Act and in accordance with Section 4(a) hereof, including
any documents incorporated by reference therein as of the date of such filing);

          (b)  The documents incorporated by reference in the Prospectus, when

thereunder, and none of such documents contained an untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein not misleading; and any further
documents so filed and incorporated by reference in the Prospectus, or any
further amendment or supplement thereto, when such documents become effective or
are filed with the Commission, as the case may be, will conform in all material
respects to the requirements of the Act or the Exchange Act, as applicable, and
the rules and regulations of the Commission thereunder and will not contain 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 not misleading;
PROVIDED, HOWEVER, that this representation and warranty shall not apply to any
statements or omissions made in reliance upon and in conformity with information
furnished in writing to the Company by any Agent expressly for use in the
Prospectus as


                                       -3-

amended or supplemented to relate to a particular issuance of Securities;

Prospectus as amended or supplemented to relate to such issuance of Securities;

          (h)  The issue and sale of the Securities, the compliance by the
Company with all of the provisions of the Securities, the Indenture, this
Agreement and any Terms Agreement, and the consummation of the transactions
herein and therein contemplated will not (i) conflict with or result in a breach
of any of the terms or provisions of, or constitute a default under, any
indenture, mortgage, deed of trust, loan agreement or other agreement or
instrument to which the Company is a party or by which the Company is bound or

severally and not jointly agrees, as agent of the Company, to use its reasonable
efforts to solicit and receive offers to purchase the Securities from the
Company upon the terms and conditions set forth in the Prospectus as amended or
supplemented from time to time.  So long as the provisions of this Agreement
relating to the solicitation of offers to purchase Securities from the Company
shall not have been terminated pursuant to Section 10 with respect to any Agent,
the Company shall not, without the consent of such Agent, solicit or accept
offers to purchase, or sell, any debt securities with a maturity at the time of
original issuance of nine months to 30 years except pursuant to this Agreement
or any Terms Agreement or except pursuant to a private placement not
constituting a public offering under the Act or except in connection with a firm
commitment underwriting pursuant to an underwriting agreement that does not
provide for a continuous offering of medium-term debt securities.  However, (i)
the Company reserves the right to sell, and may solicit and accept offers to
purchase, Securities directly on its own behalf, and, in the case of any such
sale not resulting from a solicitation made by any Agent, no commission will be
payable with respect to such sale; and (ii) the Company shall have the right at
any time to request the Agents to execute, prior to the date 15 business days
after such request, an amendment to this Agreement to provide for another person
as an Agent hereunder on substantially the same terms as the Agents hereunder on
the date of such request, and each Agent shall have the right either to execute
such amendment or to terminate the provisions of this Agreement relating to the
solicitation of offers to purchase Securities from the Company pursuant to
Section 10 with respect to such Agent.  These provisions shall not limit
Section 4(f) hereof or any similar provision included in any Terms Agreement.

          Procedural details relating to the issue and delivery of Securities,
the solicitation of offers to purchase Securities and the payment in each case
therefor shall be as set forth in the Administrative Procedure attached hereto
as Annex II as it may be amended from time to time by written agreement between
the Agents and the Company (the "Administrative Procedure").  The provisions of
the Administrative Procedure shall apply to all transactions


                                       -7-
<PAGE>

contemplated hereunder other than those made pursuant to a Terms Agreement.
Each Agent and the Company agree to perform the respective duties and
obligations specifically provided to be performed by each of them in the
Administrative Procedure.  The Company will furnish to the Trustee a copy of the
Administrative Procedure as from time to time in effect.

          The Company reserves the right, in its sole discretion, to instruct
the Agents to suspend at any time, for any period of time or permanently, the
solicitation of offers to purchase the Securities.  As soon as practicable, but
in any event not later than one business day in New York City, after receipt of
notice from the Company, the Agents will suspend solicitation of offers to
purchase Securities from the Company until such time as the Company has advised
the Agents that such solicitation may be resumed.

          The Company agrees to pay each Agent a commission, at the time of
settlement of any sale of a Security by the Company as a result of a
solicitation made by such Agent, in an amount equal to the following applicable
percentage of the principal amount of such Security sold:

                                                                 Commission

in accordance with the terms of this Agreement and (unless the Company and such
Agent shall otherwise agree) a Terms Agreement which will provide for the sale
of such Securities to, and the purchase thereof by, such Agent.  A Terms
Agreement may also specify certain provisions relating to the reoffering of such
Securities by

such Agent.  The commitment of any Agent to purchase Securities as principal,
whether pursuant to any Terms Agreement or otherwise, shall be deemed to have
been made on the basis of the representations and warranties of the Company
herein contained and shall be subject to the terms and conditions herein set
forth.  Each Terms Agreement shall specify the principal amount of Securities to
be purchased by any Agent pursuant thereto, the price to be paid to the Company
for such Securities, any provisions relating to rights of, and default by,
underwriters acting together with such Agent in the reoffering of the Securities
and the time and date and place of delivery of and payment for such Securities.
Such Terms Agreement shall also specify any requirements for opinions of

hereof.

          For each sale of Securities to an Agent as principal that is not made
pursuant to a Terms Agreement, the procedural details relating to the issue and
delivery of such Securities and payment therefor shall be as set forth in the
Administrative Procedure.  For each such sale of Securities to an Agent as
principal that is not made pursuant to a Terms Agreement, the Company agrees to
pay such Agent a commission (or grant an equivalent discount) as provided in
Section 2(a) hereof and in accordance with the schedule set forth therein.

          Each time and date of delivery of and payment for Securities to be
purchased by an Agent as principal, whether set forth in a Terms Agreement or in
accordance with the Administrative Procedure, is referred to herein as a "Time
of Delivery".

          (c)  Each Agent agrees, with respect to any Security denominated in a
currency other than U.S. dollars, as agent, directly or indirectly, not to
solicit offers to purchase, and as principal under any Terms Agreement or
otherwise, directly or indirectly, not to offer, sell or deliver, such Security
in, or to residents of, the country issuing such currency, except as permitted
by applicable law.

          3.  The documents required to be delivered pursuant to Section 6
hereof on the Commencement Date (as defined below) shall be delivered to the
Agents at the offices of Sullivan & Cromwell, 125 Broad Street, New York, New
York, at 11:00 a.m., New York City time, on the date of this Agreement, which
date and time of such delivery may be postponed by agreement between the Agents
and the Company but in no event shall be later than the day prior to the date on
which solicitation of offers to purchase Securities


                                       -9-

is commenced or on which any Terms Agreement is executed (such time and date
being referred to herein as the "Commencement Date").

          4.  The Company covenants and agrees with each Agent:

          (a)  (i)  To make no amendment or supplement to the Registration
Statement or the Prospectus (A) prior to  the Commencement Date which shall be
disapproved by any Agent promptly after reasonable notice thereof or (B) except
in the case of any document incorporated by reference in the Prospectus
subsequent to the date of any Terms Agreement or other agreement by an Agent to
purchase Securities as principal and required to be filed under the Exchange
Act, after the date of such Terms Agreement or such other agreement and prior to
the related Time of Delivery which shall be disapproved by any Agent party to
such Terms Agreement or so purchasing as principal promptly after reasonable
notice thereof; (ii) to prepare, with respect to any Securities to be sold
through or to such Agent pursuant to this Agreement, a Pricing Supplement with
respect to such Securities in a form previously approved by such Agent and to
file such Pricing Supplement pursuant to Rule 424(b) under the Act not later
than the close of business of the Commission on the fifth business day (or such
other day as Rule 424 shall require) after the date on which such Pricing
Supplement is first used; (iii) to make no amendment or supplement to the
Registration Statement or Prospectus, other than any Pricing Supplement or a
supplement relating solely to an offering of debt securities other than the
Securities or any document filed under the Act or Exchange Act which is
incorporated by reference into the Prospectus, at any time prior to having
afforded each Agent a reasonable opportunity to review and comment on it;
(iv) to file promptly all reports and any definitive proxy or information
statements required to be filed by the Company with the Commission pursuant to
Section 13(a), 13(c), 14 or 15(d) of the Exchange Act for so long as the
delivery of a prospectus is required in connection with the offering or sale of
the Securities, and during such same period to advise such Agent, promptly after
the Company receives notice thereof, of the time when any amendment to the
Registration Statement has been filed or has become effective or any supplement
to the Prospectus or any amended Prospectus, other than a supplement relating
solely to an offering of debt securities other than the Securities and other
than any Pricing Supplement that relates to Securities not purchased through or
by such Agents, has been filed with, or mailed for filing to, the Commission, of
the issuance by the Commission of any stop order or of any order preventing or
suspending the use


                                      -10-
<PAGE>

of any prospectus relating to the Securities, of the suspension of the
qualification of the Securities for offering or sale in any jurisdiction, of the
initiation or threatening of any proceeding for any such purpose, or of any
request by the Commission for the amendment or supplement of the Registration
Statement or Prospectus or for additional information; and (v) in the event of
the issuance of any such stop order or of any such order preventing or
suspending the use of any prospectus relating to the Securities or suspending
any such qualification, to use promptly its best efforts to obtain its
withdrawal;

          (b)  Promptly from time to time to take such action as such Agent
reasonably may request to qualify the Securities for offering and sale under the
securities laws of such United States jurisdictions as such Agent may request
and to comply with such laws so as to permit the continuance of sales and
dealings therein for as long as may be necessary to complete the distribution or
sale of the Securities; PROVIDED, HOWEVER, that in connection therewith the
Company shall not be required to qualify as a foreign corporation or to file a
general consent to service of process in any jurisdiction;

          (c)  To furnish such Agent with copies of the Registration Statement
and each amendment thereto, with copies of the Prospectus as each time amended
or supplemented, other than any Pricing Supplement (except as provided in the
Administrative Procedure) or a prospectus supplement relating solely to an
offering of debt securities other than the Securities, in the form in which it
is filed with the Commission pursuant to Rule 424 under the Act, and with copies
of the documents incorporated by reference therein, all in such quantities as
such Agent may reasonably request from time to time; and, if the delivery of a
prospectus is required at any time in connection with the offering or sale of
the Securities (including Securities purchased from the Company by such Agent as
principal) and if at such time any event shall have occurred as a result of
which the Prospectus as then amended or supplemented would include an untrue
statement of a material fact or omit to state any material fact necessary in
order to make the statements therein, in the light of the circumstances under
which they were made when such Prospectus is delivered, not misleading, or, if
for any other reason it shall be necessary during such same period to amend or
supplement the Prospectus or to file under the Exchange Act any document
incorporated by reference in the Prospectus in order to comply with the Act, the
Exchange Act or the Trust Indenture Act, to notify such Agent and request such
Agent, in its capacity as agent of the Company, to suspend solicitation of


                                      -11-
<PAGE>

offers to purchase Securities from the Company (and, if so notified, such Agent
shall cease such solicitations as soon as practicable, but in any event not
later than one business day later); and if the Company shall decide to amend or
supplement the Registration Statement or the Prospectus as then amended or
supplemented, to so advise such Agent promptly by telephone (with confirmation
in writing) and to prepare and cause to be filed promptly with the Commission an
amendment or supplement to the Registration Statement or the Prospectus as then
amended or supplemented that will correct such statement or omission or effect
such compliance; PROVIDED, HOWEVER, that if during such same period such Agent
continues to own Securities purchased from the Company by such Agent as
principal or such Agent is otherwise required to deliver a prospectus in respect
of transactions in the Securities, the Company shall promptly prepare and file
with the Commission such an amendment or supplement;

          (d)  To make generally available to its security holders as soon as
practicable, but in any event not later than eighteen months after (i) the
effective date of the Registration Statement (as defined in Rule 158(c)),
(ii) the effective date of each post-effective amendment to the Registration
Statement, and (iii) the date of each filing by the Company with the Commission
of an Annual Report on Form 10-K that is incorporated by reference in the
Registration Statement, an earning statement of the Company and its subsidiaries
(which need not be audited) complying with Section 11(a) of the Act and the
rules and regulations of the Commission thereunder (including, at the option of
the Company, Rule 158);

          (e)  So long as any Securities are outstanding, to furnish to each
Agent copies of all reports or other communications (financial or other)
furnished to stockholders, and deliver to such Agent (i) as soon as they are
available, copies of any reports and financial statements furnished to or filed
with the Commission or any national securities exchange on which any class of
securities of the Company is listed; and (ii) such additional information
concerning the business and financial condition of the Company as such Agent may
from time to time reasonably request (such financial statements to be on a
consolidated basis to the extent the accounts of the Company and its
subsidiaries are consolidated in reports furnished to its stockholders generally
or to the Commission);

          (f)  That, from the date of any Terms Agreement with such Agent or
other agreement by such Agent to purchase Securities as principal, if required
by such Terms Agreement


                                      -12-
<PAGE>

or other agreement, and continuing to and including the earlier of (i) the
termination of the trading restrictions for the Securities purchased thereunder,
as notified to the Company by such Agent and (ii) the related Time of Delivery,
the Company will not, without the prior written consent of such Agent, offer,
sell, contract to sell or otherwise dispose of any debt securities of the
Company which both mature more than 9 months after such Time of Delivery and are
substantially similar to the Securities, other than debt securities which the
Company has previously contracted to sell and with respect to which the Company
has advised such Agent in or in connection with such Terms Agreement or other
agreement or of which such Agent has actual knowledge thereof;

          (g)  That each acceptance by the Company of an offer to purchase
Securities hereunder (including any purchase by such Agent as principal not
pursuant to a Terms Agreement), and each execution and delivery by the Company
of a Terms Agreement with such Agent, shall be deemed to be an affirmation to
such Agent that the representations and warranties of the Company contained in
or made pursuant to this Agreement are true and correct as of the date of such
acceptance or of such Terms Agreement, as the case may be, as though made at and
as of such date, and an undertaking that such representations and warranties
will be true and correct as of the settlement date for the Securities relating
to such acceptance or as of the Time of Delivery relating to such sale, as the
case may be, as though made at and as of such date (except that such
representations and warranties shall be deemed to relate to the Registration
Statement and the Prospectus as amended and supplemented relating to such
Securities);

          (h)  That on April 15 (or if such day is not a business day, the next
succeeding business day) of every year this Agreement is in effect, beginning on
April 15, 1997, or as otherwise reasonably requested by the Agents, and each
time the Company sells Securities to such Agent as principal pursuant to a Terms
Agreement and such Terms Agreement specifies the delivery of an opinion or
opinions by Sullivan & Cromwell, counsel to the Agents, as a condition to the
purchase of Securities pursuant to such Terms Agreement, the Company shall
furnish to such counsel such papers and information as they may reasonably
request to enable them to furnish to such Agent the opinion or opinions referred
to in Section 6(b) hereof;

          (i)  That each time the Registration Statement or the Prospectus shall
be amended or supplemented (other than by a Pricing Supplement or a supplement
relating solely to


                                      -13-
<PAGE>

an offering of debt securities other than the Securities), each time a document
filed under the Act or the Exchange Act is incorporated by reference into the
Prospectus (other than a current report on Form 8-K unless reasonably requested
by the Agents) and each time the Company sells Securities to such Agent as
principal pursuant to a Terms Agreement and such Terms Agreement specifies the
delivery of an opinion under this Section 4(i) as a condition to the purchase of
Securities pursuant to such Terms Agreement, the Company shall furnish or cause
to be furnished forthwith to such Agent written opinions of Kevin J. Tierney,
Senior Vice President, Secretary and General Counsel of the Company, or other
counsel for the Company satisfactory to such Agent, dated the date of such
amendment, supplement or incorporation or the Time of Delivery relating to such
sale, as the case may be, in form satisfactory to such Agent, to the effect that
such Agent may rely on such opinion of such counsel referred to in Section 6(c)
hereof which were last furnished to such Agent to the same extent as though it
were dated the date of such letter authorizing reliance (except that the
statements in such last opinions shall be deemed to relate to the Registration
Statement and the Prospectus as amended and supplemented to such date) or, in
lieu of such opinions, opinions of the same tenor as the opinions of such
counsel referred to in Section 6(c) hereof but modified to relate to the
Registration Statement and the Prospectus as amended and supplemented to such
date;

          (j)  That on April 15 (or if such day is not a business day, the next
succeeding business day) of every year this Agreement is in effect, beginning on
April 15, 1997, or as otherwise reasonably requested by the Agents, and each
time the Company sells Securities to such Agent as principal pursuant to a Terms
Agreement and such Terms Agreement specifies the delivery of an opinion under
this Section 4(j) as a condition to the purchase of Securities pursuant to such
Terms Agreement, the Company shall furnish or cause to be furnished forthwith to
such Agent written opinions of Skadden, Arps, Slate, Meagher & Flom, special
counsel for the Company, or other counsel for the Company satisfactory to such
Agent, in form satisfactory to such Agent, to the effect that such Agent may
rely on such opinion of such counsel referred to in Section 6(d) hereof which
were last furnished to such Agent to the same extent as though it were dated the
date of such letter authorizing reliance (except that the statements in such
last opinions shall be deemed to relate to the Registration Statement and the
Prospectus as amended and supplemented to such date) or, in lieu of such
opinions, opinions of the same tenor as the opinions of such counsel referred to
in Section 6(d) hereof


                                      -14-

amended and supplemented to such date;

          (k)  That each time the Registration Statement or the Prospectus shall
be amended or supplemented (other than a supplement relating solely to an
offering of debt securities other than the Securities) and each time that a
document filed under the Act or the Exchange Act is incorporated by reference
into the Prospectus (other than a Current Report on Form 8-K unless reasonably
requested by the Agents), in either case to set forth financial information
included in or derived from the Company's consolidated financial statements or
accounting records, and each time the Company sells Securities to such Agent as
principal pursuant to a Terms Agreement and such Terms Agreement specifies the
delivery of a letter under this Section 4(k) as a condition to the purchase of
Securities pursuant to such Terms Agreement, the Company shall cause the
independent certified public accountants who have audited the financial
statements of the Company and its subsidiaries included or incorporated by
reference in the Registration Statement to furnish such Agent a letter, dated
the date of such amendment, supplement or incorporation or the Time of Delivery
relating to such sale, as the case may be, in form satisfactory to such Agent,
of the same tenor as the letter referred to in Section 6(e) hereof but modified
to relate to the Registration Statement and the Prospectus as amended or
supplemented to the date of such letter, with such changes as may be necessary
to reflect changes in the financial statements and other information derived
from the accounting records of the Company, to the extent such financial
statements and other information are available as of a date not more than five
business days prior to the date of such letter; PROVIDED, HOWEVER, that, with
respect to any financial information or other matter, such letter may reconfirm
as true and correct at such date as though made at and as of such date, rather
than repeat, statements with respect to such financial information or other
matter made in the letter referred to in Section 6(e) hereof which was last
furnished to such Agent; and

          (l)  That each time the Registration Statement or the Prospectus shall

same tenor as the certificates referred to in said Section 6(h) but modified to
relate to the Registration Statement and the Prospectus as amended and
supplemented to such date.

          5.  The Company covenants and agrees with each Agent that the Company
will pay or cause to be paid the following:  (i) the fees, disbursements and

               (i)  The Company has been duly incorporated and is validly
          existing as a corporation in good standing under the laws of the

             (iii)  The Company is qualified to do business, and is in good
          standing, as a foreign corporation under the laws of each jurisdiction
          in which the business conducted by it requires such qualification or,
          if not so qualified and in good standing in any such jurisdiction,
          such failure to be so qualified and in good standing, as of the date
          of this opinion, will not result in liabilities material to the
          business of the Company;

              (iv)  Each subsidiary of the Company has been duly organized, and
          is subsisting and in good standing as a corporation under the laws of

          set forth in the Prospectus, there are no legal or governmental
          proceedings pending to which the Company or any of its subsidiaries is
          a party or of which any property of the Company or any of its
          subsidiaries is the subject which, if determined adversely to the
          Company or any of its subsidiaries, would individually or in the
          aggregate have a material adverse effect on the consolidated financial
          position, stockholders' equity or results of operations of the Company
          and its subsidiaries; and, to the best of such counsel's knowledge, no
          such proceedings are threatened or contemplated by governmental
          authorities or threatened by others;

              (vi)  This Agreement and any applicable Terms Agreement have been
          duly authorized, executed and delivered by the Company;

          obligations of the Company entitled to the benefits provided by the
          Indenture, except to the extent that the enforcement thereof may be
          limited by (1) bankruptcy, insolvency, reorganization, moratorium or
          other similar laws now or hereafter in effect relating to creditors'
          rights generally and (2) general principles of equity (regardless of
          whether enforcement is considered in a proceeding at law or equity);
          and the Indenture conforms and the Securities will conform to the
          descriptions thereof in the Prospectus as amended or supplemented;

            (viii)  The Indenture has been duly authorized, executed and
          delivered by the parties thereto and constitutes a valid and legally
          binding instrument, enforceable in accordance with its terms, except
          to the extent that the enforcement thereof may be limited by (1)
          bankruptcy, insolvency, reorganization, moratorium or other similar
          laws now or thereafter in effect relating to creditors' rights
          generally and (2) general principles of equity (regardless of whether
          enforcement is considered in a proceeding at law or equity); and the

          of the transactions herein and therein contemplated will not conflict
          with or result in a breach or violation of any of the terms or
          provisions of, or constitute a default under, any indenture, mortgage,
          deed of trust, loan agreement or other agreement or instrument known
          to such counsel to which the Company is a party or by which the
          Company is bound or to which any of the property or assets of the
          Company is subject, nor will such actions result in any violation of
          the provisions of the Certificate of Incorporation or By-Laws of the
          Company or any statute or any order, rule or regulation known to such
          counsel of any court or governmental agency or body having
          jurisdiction over the Company or any of its properties;


                                      -20-
<PAGE>

               (x)  No consent, approval, authorization, order, registration or
          qualification of or with any court or governmental agency or body is
          required for the solicitation of offers to purchase Securities, the
          issue and sale of the Securities or the consummation by the Company of
          the other transactions contemplated by this Agreement, any applicable
          Terms Agreement or the Indenture, except such as have been obtained
          under the Act and the Trust Indenture Act and such consents,
          approvals, authorizations, registrations or qualifications as may be
          required under state securities, insurance or Blue Sky laws in
          connection with the solicitation by the Agents of offers to purchase
          Securities from the Company and with purchases of Securities by an
          Agent as principal, as the case may be, in each case in the manner
          contemplated hereby;

              (xi)  The documents incorporated by reference in the Prospectus as
          amended or supplemented (other than the financial statements and
          related schedules therein, as to which such counsel need express no
          opinion), when they became effective or were filed with the
          Commission, as the case may be, complied as to form in all material
          respects with the requirements of the Act or the Exchange Act, as
          applicable, and the rules and regulations of the Commission
          thereunder; and he has no reason to believe that any of such
          documents, when they became effective or were so filed, as the case
          may be, contained, in the case of a registration statement which
          became effective under the Act, an untrue statement of a material fact
          or omitted to state a material fact required to be stated therein or
          necessary to make the statements therein not misleading, or, in the
          case of other documents which were filed under the Act or the Exchange
          Act with the Commission, an untrue statement of a material fact or
          omitted to state a material fact necessary in order to make the
          statements therein, in the light of the circumstances under which they
          were made when such documents were so filed, not misleading; and

             (xii)  The Registration Statement and the Prospectus as amended and
          supplemented and any further amendments and supplements thereto made
          by the Company prior to the date of such opinion (other than the
          financial statements and related schedules therein, as to which such
          counsel need


                                      -21-

          express no opinion) comply as to form in all material respects with
          the requirements of the Act and the Trust Indenture Act and the rules
          and regulations thereunder.

          In addition, such counsel shall state that he has no reason to believe
that, as of its effective date, the Registration Statement or any further
amendment thereto made by the Company prior to the date of such opinion (other
than the financial statements and related schedules therein, as to which such
counsel need express no opinion) contained an untrue statement of a material
fact or omitted to state a material fact required to be stated therein or
necessary to make the statements therein not misleading or that, as of its date,
the Prospectus as amended or supplemented or any further amendment or supplement
thereto made by the Company prior to the date of such opinion (other than the
financial statements and related schedules therein, as to which such counsel
need express no opinion) contained an untrue statement of a material fact or
omitted to state a material fact necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading or
that, as of the date of such opinion, either the Registration Statement or the
Prospectus as amended or supplemented or any amendment or supplement thereto
made by the Company prior to the date of such opinion (other than the financial
statements and related schedules therein, as to which such counsel need express
no opinion) contains an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances in which they were made, not
misleading; and he shall state that he does not know of any amendment to the
Registration Statement required to be filed or any contracts or other documents
of a character required to be filed as an exhibit to the Registration Statement
or required to be incorporated by reference into the Prospectus as amended or
supplemented or required to be described in the Registration Statement or the
Prospectus as amended or supplemented which are not filed or incorporated by
reference or described as required;

          (d)  Skadden, Arps, Slate, Meagher & Flom, special counsel for the
Company, or other counsel satisfactory to such Agent shall have furnished to
such Agent their written opinions, dated the Commencement Date and each
applicable date referred to in Section 4(j) hereof that is on or prior to such
Solicitation Time or Time of Delivery, as the case may be, in form and substance
satisfactory to such Agent, to the effect that:


                                      -22-
<PAGE>

          (i)  The Indenture has been duly executed authorized and delivered by
the Company and is a valid and binding agreement, enforceable against the
Company in accordance with its terms, except to the extent that enforcement
thereof may be limited by (1) bankruptcy, insolvency, reorganization, fraudulent
transfer, moratorium or other similar laws now or hereafter in effect relating
to or affecting creditors' rights generally, (2) general principles of equity
(regardless of whether enforceability is considered in a proceeding at law or in
equity), (3) requirements that a claim with respect to any Securities
denominated other than in United States dollars (or a judgment denominated other
than in United States dollars in respect of such claim) be converted into United
States dollars at a rate of exchange prevailing on a date determined pursuant to
applicable law and (4) governmental authority to limit, delay or prohibit the
making of payments in foreign currencies or composite currencies or currency
units; and

          (ii)  The Securities, when executed and authenticated in accordance
with the terms of the Indenture, and issued, sold and delivered by the Company
pursuant to this Agreement against payment of the consideration set forth in
this Agreement, will be valid and binding obligations of the Company entitled to
the benefits of the Indenture and enforceable against the Company in accordance
with their terms, except to the extent that enforcement thereof may be limited
by (1) bankruptcy, insolvency, reorganization, fraudulent transfer, moratorium
or similar laws now or hereafter in effect relating to or affecting creditors'
rights generally, (2) general principles of equity (regardless of whether
enforceability is considered in a proceeding at law or in equity),
(3) requirements that a claim with respect to any Securities denominated other
than in United States dollars (or a judgment denominated in other than United
States dollars in respect of such claim) be converted into United States dollars
at a rate of exchange prevailing on a date determined pursuant to applicable law
and (4) governmental authority to limit, delay or prohibit the making of
payments in foreign currencies or composite currencies or currency units;

          (e)  (i) Not later than 10:00 a.m., New York City time, on the
Commencement Date and on each applicable date referred to in Section 4(k) hereof
that is on or prior to such Solicitation Time or Time of Delivery, as the case
may be, the independent certified public accountants who have audited the
financial statements of the Company and its subsidiaries included or
incorporated by reference in the Registration Statement shall have furnished to
such Agent a


                                      -23-
<PAGE>

letter, dated the Commencement Date or such applicable date, as the case may be,
in form and substance satisfactory to such Agent, to the effect set forth in
Annex III hereto;

          (f)  (i)  Neither the Company nor any of its subsidiaries shall have
sustained since the date of the latest audited financial statements included or
incorporated by reference in the Prospectus as amended or supplemented any loss
or interference with its business from fire, explosion, flood or other calamity,
whether or not covered by insurance, or from any labor dispute or court or
governmental action, order or decree, otherwise than as set forth or
contemplated in the Prospectus as amended or supplemented and (ii) since the
respective dates as of which information is given or incorporated by reference
in the Prospectus as amended or supplemented there shall not have been any
change in the capital stock or long-term debt of the Company or any of its
subsidiaries or any change, or any development involving a prospective change,
in or affecting the general affairs, management, financial position,
stockholders' equity or results of operations of the Company and its
subsidiaries, otherwise than as set forth or contemplated in the Prospectus as
amended or supplemented, the effect of which, in any such case described in
clause (i) or (ii), is in the judgment of such Agent so material and adverse as
to make it impracticable or inadvisable to proceed with the solicitation by such
Agent of offers to purchase Securities from the Company or the purchase by such
Agent of Securities from the Company as principal, as the case may be, on the
terms and in the manner contemplated in the Prospectus as amended or
supplemented;

          (g)  There shall not have occurred any of the following:  (i) a
suspension or material limitation in trading in securities generally on the New
York Stock Exchange; (ii) a general moratorium on commercial banking activities
in New York declared by either Federal or New York State authorities; (iii) the
outbreak or material escalation of hostilities involving the United States or
the declaration by the United States of a national emergency or war, if the
effect of any such event specified in this clause (iii) in the judgment of such
Agent makes it impracticable or inadvisable to proceed with the solicitation of
offers to purchase Securities or the purchase of Securities from the Company as
principal, pursuant to the applicable Terms Agreement or otherwise, as the case
may be, on the terms and in the manner contemplated in the Prospectus as amended
or supplemented; (iv) any downgrading in the rating accorded the Company's debt
securities by any "nationally recognized statistical rating organization", as
that term is defined by the Commission for purposes of Rule 436(g)(2)


                                      -24-
<PAGE>

under the Act; or (v) any such "nationally recognized statistical rating
organization" shall have publicly announced that it has under surveillance or
review, with possible negative implications, its rating of any of the Company's
debt securities; and

          (h)  The Company shall have furnished or caused to be furnished to
such Agent certificates of officers of the Company dated the Commencement Date
and each applicable date referred to in Section 4(l) hereof that is on or prior
to such Solicitation Time or Time of Delivery, as the case may be, in such form
and executed by such officers of the Company as shall be satisfactory to such
Agent, as to the accuracy of the representations and warranties of the Company
herein at and as of the Commencement Date or such applicable date, as the case
may be, as to the performance by the Company of all of its obligations hereunder
to be performed at or prior to the Commencement Date or such applicable date, as
the case may be, as to the matters set forth in subsections (a) and (f) of this
Section 6, and as to such other matters as such Agent may reasonably request.

          7.  (a)  The Company will indemnify and hold harmless each Agent
against any losses, claims, damages or liabilities, joint or several, to which
such Agent may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement, the Prospectus, the Prospectus as amended or supplemented or any
other prospectus relating to the Securities, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, and will reimburse such Agent for any
legal or other expenses reasonably incurred by it in connection with
investigating or defending any such action or claim as such expenses are
incurred; PROVIDED, HOWEVER, that the Company shall not be liable in any such
case to the extent that any such loss, claim, damage or liability arises out of
or is based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in any Preliminary Prospectus, the Registration Statement,
the Prospectus, the Prospectus as amended or supplemented or any other
prospectus relating to the Securities, or any such amendment or supplement, in
reliance upon and in conformity with written information furnished to the
Company by such Agent expressly for use therein; and PROVIDED FURTHER, that the
Company shall not be liable to such Agent under the indemnity


                                      -25-
<PAGE>

agreement in this subsection (a) with respect to any Preliminary Prospectus to
the extent that any such loss, claim, damage or liability of such Agent results
from the fact such Agent sold Securities to a person to whom there was not sent
or given, at or prior to the written confirmation of such sale, a copy of the
Prospectus (excluding documents incorporated by reference) or of the Prospectus
as then amended or supplemented (excluding documents incorporated by reference)
in any case where such delivery is required by the Act if the Company has
previously furnished copies thereof to such Agent and the loss, claim, damage or
liability of such Agent results from an untrue statement or omission of a
material fact contained in the Preliminary Prospectus which was corrected in the
Prospectus (or the Prospectus as amended or supplemented).

          (b)  Each Agent will indemnify and hold harmless the Company against
any losses, claims, damages or liabilities to which the Company may become
subject, under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, the Registration Statement, the Prospectus, the
Prospectus as amended or supplemented or any other prospectus relating to the
Securities, or any amendment or supplement thereto, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
in each case to the extent, but only to the extent, that such untrue statement
or alleged untrue statement or omission or alleged omission was made in any
Preliminary Prospectus, the Registration Statement, the Prospectus, the
Prospectus as amended or supplemented or any other prospectus relating to the
Securities, or any such amendment or supplement, in reliance upon and in
conformity with written information furnished to the Company by such Agent
expressly for use therein; and will reimburse the Company for any legal or other
expenses reasonably incurred by the Company in connection with investigating or
defending any such action or claim as such expenses are incurred.

          (c)  Promptly after receipt by an indemnified party under subsection
(a) or (b) above of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified


                                      -26-
<PAGE>

party otherwise than under such subsection.  In case any such action shall be
brought against any indemnified party and it shall notify the indemnifying party
of the commencement thereof, the indemnifying party shall be entitled to
participate therein and, to the extent that it shall wish, jointly with any
other indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party (who shall not, except with the
consent of the indemnified party, be counsel to the indemnifying party), and,
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party under such subsection for any legal expenses of
other counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable
costs of investigation.

          (d)  If the indemnification provided for in this Section 7 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and each Agent on the
other from the offering of the Securities to which such loss, claim, damage or
liability (or action in respect thereof) relates.  If, however, the allocation
provided by the immediately preceding sentence is not permitted by applicable
law or if the indemnified party failed to give the notice required under
subsection (c) above, then each indemnifying party shall contribute to such
amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company on the one hand and each Agent on the other in connection
with the statements or omissions which resulted in such losses, claims, damages
or liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations.  The relative benefits received by the Company on the
one hand and each Agent on the other shall be deemed to be in the same
proportion as the total net proceeds from the sale of such Securities (before
deducting expenses) received by the Company bear to the total commissions or
discounts received by such Agent in respect thereof.  The relative fault shall
be determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission


                                      -27-
<PAGE>

or alleged omission to state a material fact relates to information supplied by
the Company on the one hand or by any Agent on the other and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.  The Company and each Agent agree that it
would not be just and equitable if contribution pursuant to this subsection (d)
were determined by per capita allocation (even if all Agents were treated as one
entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to above in this
subsection (d).  The amount paid or payable by an indemnified party as a result
of the losses, claims, damages or liabilities (or actions in respect thereof)
referred to above in this subsection (d) shall be deemed to include any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this subsection (d), an Agent shall not be required to contribute
any amount in excess of the amount by which the total public offering price at
which the Securities purchased by or through it were sold exceeds the amount of
any damages which such Agent has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission.  No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.  The obligations of each of the
Agents under this subsection (d) to contribute are several in proportion to
their respective purchases made by or through it to which such loss, claim,
damage or liability (or action in respect thereof) relates and are not joint.

          (e)  The obligations of the Company under this Section 7 shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each person, if any, who controls any
Agent within the meaning of the Act; and the obligations of each Agent under
this Section 7 shall be in addition to any liability which such Agent may
otherwise have and shall extend, upon the same terms and conditions, to each
officer and director of the Company and to each person, if any, who controls the
Company within the meaning of the Act.

          8.  Each Agent, in soliciting offers to purchase Securities from the
Company and in performing the other obligations of such Agent hereunder (other
than in respect of any purchase by an Agent as principal, pursuant to a Terms
Agreement or otherwise) is acting solely as agent for the Company and not as
principal.  Each Agent will make


                                      -28-
<PAGE>

reasonable efforts to assist the Company in obtaining performance by each
purchaser whose offer to purchase Securities from the Company was solicited by
such Agent and has been accepted by the Company, but such Agent shall not have
any liability to the Company in the event such purchase is not consummated for
any reason.  If the Company shall default on its obligation to deliver
Securities to a purchaser whose offer it has accepted, the Company shall
(i) hold each Agent harmless against any loss, claim or damage arising from or
as a result of such default by the Company and (ii) notwithstanding such
default, pay to the Agent that solicited such offer any commission to which it
would be entitled in connection with such sale.

          9.  The respective indemnities, agreements, representations,
warranties and other statements by any Agent and the Company set forth in or
made pursuant to this Agreement shall remain in full force and effect regardless
of any investigation (or any statement as to the results thereof) made by or on
behalf of any Agent or any controlling person of any Agent, or the Company, or
any officer or director or any controlling person of the Company, and shall
survive each delivery of and payment for any of the Securities.

         10.  The provisions of this Agreement relating to the solicitation of
offers to purchase Securities from the Company may be suspended or terminated at
any time by the Company as to any Agent or by any Agent as to such Agent upon
the giving of written notice of such suspension or termination to such Agent or
the Company, as the case may be.  In the event of any such termination or
suspension, no party will have any liability, duty or obligation to any other
party hereto, except that (x) this Agreement shall remain in full force and
effect with respect to any Agent as to which such suspension or termination has
not occurred, (y) this Agreement shall remain in full force and effect with
respect to the rights and obligations of any party which have previously accrued
or which relate to Securities which are already issued, agreed to be issued or
the subject of a pending offer at the time of such suspension or termination and
(z) in any event, this Agreement shall remain in full force and effect insofar
as the fourth paragraph of Section 2(a), Section 4(d), Section 4(e), Section 5,
Section 7, Section 8 and Section 9 hereof are concerned.

         11.  Except as otherwise specifically provided herein or in the
Administrative Procedure, all statements, requests, notices and advices
hereunder shall be in writing, or by telephone if promptly confirmed in writing,
and if to Goldman, Sachs & Co. shall be sufficient in all respects


                                      -29-

when delivered or sent by facsimile transmission or registered mail to 85 Broad

Attention:  Registration Department; if to Morgan Stanley & Co., Incorporated

New York, Attention:  Manager Credit Department; and if to the Company shall be
sufficient in all respects when delivered or sent by facsimile transmission or
registered mail to it at its address set forth in the Prospectus.

         12.  This Agreement and any Terms Agreement shall be binding upon, and
inure solely to the benefit of, each Agent and the Company, and to the extent
provided in Section 7, Section 8 and Section 9 hereof, the officers and
directors of the Company and any person who controls any Agent or the Company,
and their respective personal representatives, successors and assigns, and no
other person shall acquire or have any right under or by virtue of this
Agreement or any Terms Agreement.  No purchaser of any of the Securities through
or from any Agent hereunder shall be deemed a successor or assign by reason of
such purchase.

         13.  Time shall be of the essence in this Agreement and any Terms
Agreement.  As used herein, the term "business day" shall mean any day when the
office of the Commission in Washington, D.C. is open for business.

         14.  THIS AGREEMENT AND ANY TERMS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK.

         15.  This Agreement and any Terms Agreement may be executed by any one
or more of the parties hereto and thereto in any number of counterparts, each of
which shall be deemed to be an original, but all of such respective counterparts
shall together constitute one and the same instrument.

         16.  This Agreement may be amended or supplemented if, but only if,
such amendment or supplement is in writing and is signed by the Company and each
Agent; PROVIDED that the Company may from time to time, on 15 days prior written
notice to the Agents but without the consent of any Agent, amend this Agreement
to add as a party hereto one or more additional firms registered under the
Exchange Act, whereupon each such firm shall become an Agent hereunder on


                                      -30-
<PAGE>

substantially the same terms and conditions as the other Agents that are parties
hereto.  Each Agent shall sign any amendment or supplement giving effect to the
addition of any such firm as an Agent under this Agreement or shall terminate
the provisions of this Agreement relating to the solicitation of offers to
purchase Securities from the Company pursuant to Section 10 with respect to such
Agent.

[Goldman, Sachs & Co.
85 Broad Street
New York, New York 10004]

[Morgan Stanley & Co. Incorporated
1251 Avenue of the Americas
New York, New York 10020]

Dear Sirs:

          UNUM Corporation (the "Company") proposes, subject to
the terms and conditions stated herein and in the Distribution
Agreement, dated July __, 1996 (the "Distribution Agreement"),
between the Company on the one hand and Goldman, Sachs & Co. and
Morgan Stanley & Co. Incorporated (the "Agents"), on the other,
to issue and sell to [Goldman, Sachs & Co.] [Morgan Stanley & Co.
Incorporated] the securities specified in the Schedule hereto
(the "Purchased Securities").  Each of the provisions of the
Distribution Agreement not specifically related to the
solicitation by the Agents, as agents of the Company, of offers
to purchase Securities is incorporated herein by reference in its
entirety, and shall be deemed to be part of this Terms Agreement
to the same extent as if such provision had been set forth in
full herein.  Nothing contained herein or in the Distribution
Agreement shall make any party hereto an agent of the Company or
make such party subject to the provisions therein relating to the
solicitation of offers to purchase securities from the Company,
solely by virtue of its execution of this Terms Agreement.  Each
of the representations and warranties set forth therein shall be

                                UNUM Corporation

                            ADMINISTRATIVE PROCEDURE

          This Administrative Procedure relates to the Securities defined in the
Distribution Agreement, dated July __, 1996 (the "Distribution Agreement"),
between UNUM Corporation (the "Company") and Goldman, Sachs & Co. and Morgan
Stanley & Co. Incorporated (together, the "Agents"), to which this
Administrative Procedure is attached as Annex II.  Defined terms used herein and
not defined herein shall have the meanings given such terms in the Distribution
Agreement, the Prospectus as amended or supplemented or the Indenture.

          The procedures to be followed with respect to the settlement of sales
of Securities directly by the Company to purchasers solicited by an Agent, as
agent, are set forth below.  Part I describes procedures of general
applicability with respect to such Securities.  Part II below describes
procedures specifically and exclusively applicable (any procedure in Part I
below to the contrary notwithstanding) to such Securities which are either
Global Certificates or Book-Entry Securities (each as defined below).  The terms
and settlement details related to a purchase of Securities by an Agent, as
principal, from the Company will be set forth in a Terms Agreement pursuant to
the Distribution Agreement, unless the Company and such Agent otherwise agree as
provided in Section 2(b) of the Distribution Agreement, in which case the
procedures to be followed in respect of the settlement of such sale will be as
set forth below.  An Agent, in relation to a purchase of a Security by a
purchaser solicited by such Agent, is referred to herein as the "Selling Agent"
and, in relation to a purchase of a Security by such Agent as principal other
than pursuant to a Terms Agreement, as the "Purchasing Agent".

          The Company will advise each Agent in writing of those persons with
whom such Agent is to communicate regarding offers to purchase Securities and
the related settlement details.

          Unless otherwise specified in the applicable Pricing Supplement, each
Security will be issued only in fully registered form and will be initially
represented by either a permanent global certificate (a "Global Certificate")
delivered to the Trustee, as agent for The Depository Trust Company (the
"Depository") or a certificate (a "Definitive Certificate") delivered to a
person designated by an Agent.  Each security which is represented by a Global
Certificate is referred to herein as a "Book-Entry Security" (it being
understood that only such Global Certificate -- and not any such Book-Entry
Security represented thereby -- constitutes a "Security" under the Indenture).


<PAGE>

          Pursuant to Sections 301 and 1002 of the Indenture, the Company has
appointed The Chase Manhattan Bank (National Association) as Paying Agent (the
"Paying Agent") and as Calculation Agent (the "Calculation Agent") for the
Securities.  In addition, the Company has appointed The Chase Manhattan Bank
(National Association) as its agent (the "Issuing Agent") in connection with
certain procedures to be followed with respect to the settlement of sales of
Securities, as set forth herein.

     PART I:   PROCEDURES OF APPLICABILITY TO BOTH CERTIFICATED
               SECURITIES AND BOOK-ENTRY SECURITIES

POSTING RATES BY THE COMPANY:

          The Company and the Agents will discuss from time to time the rates of
interest per annum to be borne by and the maturity of Securities that may be
sold as a result of the solicitation of offers by an Agent.  The Company may
establish a fixed set of interest rates and maturities for an offering period
("posting").  If the Company decides to change already posted rates, it will
promptly advise the Agents to suspend solicitation of offers until the new
posted rates have been established with the Agents.

ACCEPTANCE OF OFFERS BY THE COMPANY:

          Each Agent will promptly advise the Company by telephone or other
appropriate means of all reasonable offers to purchase Securities, other than
those rejected by such Agent.  Each Agent may, in its discretion reasonably
exercised, reject any offer received by it in whole or in part.  Each Agent also
may make offers to the Company to purchase Securities as a Purchasing Agent.
The Company will have the sole right to accept offers to purchase Securities and
may reject any such offer in whole or in part.

          The Company will promptly notify the Selling Agent or Purchasing
Agent, as the case may be, of its acceptance or rejection of an offer to
purchase Securities.  If the Company accepts an offer to purchase Securities, it
will confirm such acceptance in writing to the Selling Agent or Purchasing
Agent, as the case may be, and the Trustee.

TO THE COMPANY BY SELLING AGENT:

          After the acceptance of an offer by the Company, the Selling Agent or
Purchasing Agent, as the case may be, will communicate the following details of
the terms of such offer (the "Sale Information") to the Company by telephone

such Pricing Supplement to the Selling Agent or Purchasing Agent, as the case

DELIVERY OF CONFIRMATION AND
PROSPECTUS TO PURCHASER BY SELLING AGENT:

          The Selling Agent will deliver to the purchaser of a Security a
written confirmation of the sale and delivery and payment instructions.  In
addition, the Selling Agent will deliver to such purchaser or its agent the
Prospectus as amended or supplemented (including the Pricing Supplement) in
relation to such Security prior to or together with the earlier of the delivery
to such purchaser or its agent of (a) the confirmation of sale (including, in
the case of a Book-Entry Security, the confirmation through the Depository's
Institutional Delivery System) or (b) the Security.

DATE OF SETTLEMENT:

          All offers solicited by a Selling Agent or made by a Purchasing Agent
and accepted by the Company will be settled on a date (the "Settlement Date")
which is the third business day after the date of acceptance of such offer,
unless the Company and the purchaser agree to settlement (a) on any other
business day after the acceptance of such offer or (b) with respect to an offer
accepted by the Company prior to 10:00 a.m., New York City time, on the date of

instruction will be given by the Company prior to 2:00 p.m., New York City time,

Securities evidenced by a Definitive Certificate, the Settlement Date is the
date of acceptance by the Company of the offer to purchase such Securities in
which case such instruction will be given by the Company by 11:00 a.m., New York
City time.  The Trustee will authenticate and deliver to the Issuing Agent each
Security in accordance with the Company's instructions.


                                      II-5
<PAGE>


PREPARATION AND DELIVERY OF SECURITIES
BY ISSUING AGENT AND RECEIPT OF PAYMENT THEREFOR:

          The Issuing Agent will prepare each Security and appropriate receipts
that will serve as the documentary control of the transaction.

          In the case of a sale of Securities to a purchaser solicited by an
Agent, the Issuing Agent will, by 2:15 p.m., New York City time, on the
Settlement Date, deliver the Securities to the Selling Agent for the benefit of
the purchaser of such Securities against delivery by the Selling Agent of a
receipt therefor.  On the Settlement Date the Selling Agent will deliver payment
for such Securities in immediately available funds to the Company in an amount
equal to the issue price of the Securities less the Selling Agent's commission;
provided that the Selling Agent reserves the right to withhold payment for which
it has not received funds from the purchaser.  The Company shall not use any
proceeds advanced by a Selling Agent to purchase securities or carry any
securities in violation of Regulations G, T, U or X of the Federal Reserve Board
or otherwise in violation of law.

          In the case of a sale of Securities to a Purchasing Agent, the Issuing
Agent will, by 2:15 p.m., New York City time, on the Settlement Date, deliver
the Securities to the Purchasing Agent against delivery by the Purchasing Agent
of a receipt therefor.  On the Settlement Date the Purchasing Agent will deliver
payment for such Securities in immediately available funds to the Company in an
amount equal to the issue price of the Securities less the Purchasing Agent's
discount.

FAILURE OF PURCHASER TO PAY SELLING AGENT:

          If a purchaser (other than a Purchasing Agent) fails to make payment
to the Selling Agent for a Security or the Selling Agent fails to make payment
to the Company, the Selling Agent will promptly notify the Trustee and the
Company thereof by telephone (confirmed in writing) or by facsimile transmission
or other acceptable written means.  The Selling Agent will immediately return
the Security to the Issuing Agent.  Immediately upon receipt of such Security by
the Issuing Agent, the Company will return to the Selling Agent an amount equal
to the amount previously paid to the Company in respect of such Security.  The
Company will reimburse the Selling Agent on an equitable basis for its loss of
the use of funds during the period when they were credited to the account of the
Company.

          The Issuing Agent will cancel the Security in respect of which the
failure occurred, make appropriate entries in its records and, unless otherwise
instructed by the Company, destroy the Security.

     PART II:  PROCEDURES APPLICABLE TO BOOK-ENTRY
               SECURITIES AND GLOBAL CERTIFICATES

          In connection with the qualification of Book-Entry Securities for
eligibility in the book-entry system maintained by the Depository, the Trustee
and the Paying Agent will perform the custodial, document control and
administrative functions described below, in accordance with their respective
obligations under a Letter of Representations from the Company and the Trustee
to the Depository, dated July __, 1996, and a Medium-Term Note Certificate
Agreement, dated March 10, 1989, between The Chase Manhattan Bank (National
Association) and the Depository (the "Certificate Agreement"), and the
obligations of the Trustee as a participant in the Depository, including the
Depository's Same-Day Funds Settlement System ("SDFS").  It is understood that
the ownership interests of purchasers of Book-Entry Securities will be credited
to the book-entry accounts of one or more participants in the Depository (each a
"Participant") in accordance with the Depository's customary practices and
reflected in the records of such Participants or one or more indirect
Participants in the Depository designated by such purchasers in accordance with
the arrangements between such purchasers and such Participants and indirect
participants.  As used in this Part II, the term "Business Day" means each
Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which
banking institutions in The City of New York are authorized or obligated by law
or executive order to close.

Issuance:                All Fixed Rate Securities which are Book-Entry
                         Securities and have the same Original Issue Date,
                         redemption provisions, Interest Payment Dates, interest
                         rate, interest payment periods and Stated Maturity
                         (collectively, the "Fixed Rate Terms") will be
                         represented initially by a single Global Certificate in
                         fully registered form without coupons; all Floating
                         Rate Securities which are Book-Entry Securities and
                         have the same Original Issue Date, redemption
                         provisions, Interest Payment Dates, interest payment
                         periods, Interest Rate Basis, Initial Interest Rate,
                         Index Maturity, Spread or Spread Multiplier, if any,
                         Minimum Interest Rate, if any, Maximum Interest Rate,
                         if any, and Stated Maturity (collectively, the
                         "Floating Rate Terms") will be represented initially by
                         a single Global Certificate in fully registered form
                         without coupons; and all Zero Coupon

<PAGE>


                         Securities which are Book-Entry Securities and have the
                         same Original Issue Date, redemption provisions, Yield
                         to Maturity, Specified Currency and Stated Maturity
                         (collectively, the "Zero Coupon Terms") will be
                         represented initially by a single Global Certificate in
                         fully registered form without coupons.

Identification:          The Company has arranged with the CUSIP Service Bureau
                         of Standard & Poor's Corporation (the "CUSIP Service
                         Bureau") for the reservation of approximately 900 CUSIP
                         numbers which have been reserved for future assignment
                         and relating to Book-Entry Securities, and the Company
                         has delivered to the Issuing Agent and the Depository
                         such list of such CUSIP numbers.  The Company will
                         assign CUSIP numbers to Global Certificates
                         representing Book-Entry Securities as described below
                         under Settlement Procedure C.  The Depository will
                         notify the CUSIP Service Bureau periodically of the
                         CUSIP numbers that the Company has assigned to Global
                         Certificates representing Book-Entry Securities.  The
                         Trustee will notify the Company at any time when fewer
                         than 100 of the reserved CUSIP numbers remain
                         unassigned to Global Certificates representing Book-
                         Entry Securities, and, if it deems necessary, the
                         Company will reserve additional CUSIP numbers for
                         assignment to Global Certificates representing
                         Book-Entry Securities.  Upon obtaining such additional
                         CUSIP numbers, the Company will deliver a list of such
                         additional numbers to the Issuing Agent and the
                         Depository.  Book-Entry Securities having an aggregate
                         principal amount in excess of $200,000,000 and
                         otherwise required to be represented by the same Global
                         Certificate will instead be represented by two or more
                         Global Certificates which shall all be assigned the
                         same CUSIP number.

Registration:            Each Global Certificate will be registered in the name
                         of Cede & Co., as

                         maintained by the Trustee under the Indenture.  On the

                         Day.

                         effected in accordance with arrangements in effect
                         between Participants (and in certain cases, one or more
                         indirect participants in the Depository) and the
                         beneficial transferors and beneficial transferees of
                         such Book-Entry Security, and the interests of
                         Participants therein will be reflected as appropriate
                         by book entries made by the Depository.

Exchanges:               The Issuing Agent may deliver to the Depository and the
                         CUSIP Service Bureau at any time a written notice
                         specifying (a) the CUSIP numbers of two or more Global
                         Certificates (i) having the same Fixed Rate Terms,
                         Floating Rate Terms or Zero Coupon Terms, as the case
                         may be (except that Original Issue Dates need not be
                         the same), (ii) for which interest (if any) has been
                         paid to the same date and (iii) which otherwise
                         constitute Securities of the same series and tenor
                         under the Indenture; (b) a date, occurring at least 30
                         days after such written notice is delivered and at
                         least 30 days before the next Interest Payment Date (if
                         any) for such Book-Entry Securities, on which such
                         Global Certificates shall be exchanged for a single
                         replacement Global Certificate; and (c) a new CUSIP
                         number, obtained from the Company, to be assigned to
                         such replacement Global Certificate.  Upon receipt of
                         such a notice, the Depository will send to its
                         participants (including the Issuing Agent) a written
                         reorganization notice to the effect that such exchange
                         will occur on such date.  Prior to the specified
                         exchange date, the Issuing


                                      II-9
<PAGE>


                         Agent will deliver to the CUSIP Service Bureau written
                         notice setting forth such exchange date and the new
                         CUSIP number and stating that, as of such exchange
                         date, the CUSIP numbers of the Global Certificates to
                         be exchanged will no longer be valid.  On the specified
                         exchange date, the Issuing Agent will exchange such
                         Global Certificates for a single Global Certificate
                         authenticated by the Trustee and bearing the new CUSIP
                         number, and the CUSIP numbers of the exchanged Global
                         Certificates will, in accordance with CUSIP Service
                         Bureau procedures, be retired and not reassigned.
                         Notwithstanding the foregoing, if the Global
                         Certificates to be exchanged exceed $200,000,000 in
                         aggregate principal amount, one replacement Global
                         Certificate will be authenticated and issued to
                         represent each $200,000,000 of principal amount of the
                         exchanged Global Certificates and an additional Global
                         Certificate will be authenticated and issued to
                         represent any remaining principal amount of such Global
                         Certificates (see "Denominations" below).

Denominations:           All Book-Entry Securities will be denominated in U.S.
                         dollars.  Book-Entry Securities will be issued in
                         denominations of $100,000 and any larger denomination
                         which is an integral multiple of $1,000.  Global
                         Certificates will be denominated in principal amounts
                         not in excess of $200,000,000.  If one or more
                         Book-Entry Securities having an aggregate principal
                         amount in excess of $200,000,000 would, but for the
                         preceding sentence, be represented by a single Global
                         Certificate, then one Global Certificate will be issued
                         to represent each $200,000,000 principal amount of such
                         Book-Entry Security or Book-Entry Securities and an
                         additional Global Certificate will be issued to
                         represent any remaining principal amount of such
                         Book-Entry Security or Book-Entry Securities.  In such
                         a case, each of the Global Certificates representing
                         such Book-Entry Security or Securities

                         instructions in writing to the Paying Agent.  For
                         principal payments at Maturity, prior to 10:00 a.m.,

                         date, if the initial interest rate for a Floating Rate
                         Note is not known at the time that Settlement Procedure
                         A is completed, Settlement Procedures B and C shall be
                         completed as soon as such rates have been determined,
                         but no later than 11:00 a.m. and 2:00 p.m., New York
                         City time, respectively, on the second Business Day
                         before the Settlement Date.  Settlement Procedure I is
                         subject to extension of Fedwire closing deadlines and
                         in the other events specified in the SDFS operating
                         procedures in effect on the settlement date.

                         If settlement of a Book-Entry Security is rescheduled
                         or cancelled, the Company will as soon as practicable
                         give the Trustee notice to such effect.  The Trustee
                         will deliver to the Depository, through the
                         Depository's Participant Terminal System, a
                         cancellation message (the form of which has been
                         previously furnished to the Trustee by the Depository)
                         to such effect by no later than 2:00 p.m., New York
                         City time, on the Business Day immediately preceding
                         the scheduled Settlement Date (provided the Issuing
                         Agent received such notice from the Company by noon on
                         the business day immediately preceding the Settlement

                         Date) and in any case as soon as practicable.  A copy
                         of such message will be routed through the facilities
                         of the Depository to the Selling Agent and Standard &
                         Poor's Corporation.

Failure to Settle:       If the Issuing Agent fails to enter in timely fashion
                         an SDFS deliver order with respect to any Book-Entry
                         Security or any portion of a Global Certificate
                         representing a Book-Entry Security pursuant to
                         Settlement Procedure G, or if the Selling Agent or the
                         Purchasing Agent, as the case may be, fails to enter in
                         timely fashion an SDFS deliver order with respect to
                         such Book-Entry Security pursuant to Settlement
                         Procedure H, the Issuing Agent may deliver to the
                         Depository, through the Depository's Participant
                         Terminal System, as soon as practicable, a withdrawal
                         message (the form of which has been previously
                         furnished to the Issuing Agent by the Depository)
                         instructing the Depository to debit such Book-Entry
                         Security to the participant account of the Issuing
                         Agent maintained at the Depository.  A copy of such
                         message will be routed through the facilities of the
                         Depository to such Agent.  The Depository will process
                         the withdrawal message, provided that such participant
                         account contains Book-Entry Securities having the same
                         Fixed Rate Terms, Floating Rate Terms or Zero Coupon
                         Terms, as the case may be, having an aggregate
                         principal amount that is at least equal to the
                         principal amount to be debited. If withdrawal messages
                         are processed with respect to all the Book-Entry
                         Securities represented by a particular Global
                         Certificate, the Issuing Agent will cancel immediately
                         such Global Certificate, make appropriate entries in
                         its records and, unless otherwise instructed by the
                         Company, destroy the Global Certificate. The CUSIP
                         number assigned to such Global Certificate shall, in
                         accordance with CUSIP Service Bureau procedures, be
                         retired and not reassigned. If withdrawal messages
                         are processed with 


                                      II-22
<PAGE>
                         respect to only a portion of the Book-Entry
                         Securities represented by a particular Global
                         Certificate, the Issuing Agent will exchange such
                         Global Certificate for two Global Certificates
                         authenticated by the Trustee, one of which
                         shall represent the Book-Entry Securities for which
                         withdrawal messages are processed and shall be
                         cancelled by the Trustee and destroyed immediately
                         after issuance, and the other of which shall represent
                         the other Book-Entry Securities previously represented
                         by the surrendered Global Certificate and shall bear
                         the CUSIP number of the surrendered Global Certificate.
                         The Company will reimburse such Agent on an equitable
                         basis for its loss of the use of funds during any
                         period when the funds were credited to the account of
                         the Company in connection with such attempted
                         settlement.

                         If the purchase price for any Book-Entry Security is
                         not timely paid to the Participants with respect to
                         such Security by the beneficial purchaser thereof or by
                         a person, including an indirect participant in the
                         Depository, acting on behalf of such purchaser (other
                         than the Purchasing Agent, if any), such Participants
                         and, in turn, the Selling Agent or the Purchasing
                         Agent, as the case may be, may enter SDFS deliver
                         orders through the Depository's Participant Terminal
                         System reversing the orders entered pursuant to
                         Settlement Procedures G and H, respectively.
                         Immediately thereafter, the Issuing Agent will deliver
                         the withdrawal message and take the related actions
                         described in the preceding paragraph.  The Company will
                         reimburse such Agent on an equitable basis for its loss
                         of the use of funds during any period when the funds
                         were credited to the account of the Company in
                         connection with such attempted settlement.

                         Notwithstanding the foregoing, upon any failure to
                         settle with respect to any


                                      II-23
<PAGE>


                         Book-Entry Security or any portion of a Global
                         Certificate representing a Book-Entry Security, the
                         Depository may take any actions in accordance with its
                         SDFS operating procedures then in effect.  In the event
                         of a failure to settle with respect to any Book-Entry
                         Security that was to have been represented by a Global
                         Certificate also representing other Book-Entry
                         Securities, the Issuing Agent will provide, in
                         accordance with Settlement Procedures D and E, for the
                         authentication and issuance of a Global Certificate
                         representing the remaining principal amount to have
                         been represented by such Global Certificate and will
                         make appropriate entries in its records.

Issuing and Paying
  Agents Not to Risk
  Funds:                 Nothing herein will be deemed to require the Issuing
                         Agent or the Paying Agent to risk or expend its own
                         funds in connection with any payment to the Company,
                         the Agents, the Depository or any Securityholder, it
                         being understood by all parties that payments made by
                         the Issuing Agent or the Paying Agent to any party will
                         be made only to the extent that funds are provided to
                         the Issuing Agent or the Paying Agent, as the case may
                         be, for such purpose.

                       ACCOUNTANT'S LETTER

          Pursuant to Section 4(k) and Section 6(e), as the case
may be, of the Distribution Agreement, the accountants shall
furnish letters to the effect that:

          (i) They are independent certified public accountants
     with respect to the Company and its subsidiaries within the
     meaning of the Act and the applicable published rules and
     regulations thereunder;

         (ii) In their opinion, the financial statements and any
     supplementary financial information and schedules audited
     (and, if applicable, prospective financial statements and/or
     pro forma financial information examined) by them and
     included or incorporated by reference in the Registration
     Statement or the Prospectus comply as to form in all
     material respects with the applicable accounting
     requirements of the Act or the Exchange Act, as applicable,
     and the related published rules and regulations thereunder;
     and, if applicable, they have made a review in accordance
     with standards established by the American Institute of
     Certified Public Accountants of the consolidated interim
     financial statements, selected financial data, pro forma
     financial information, prospective financial statements
     and/or condensed financial statements derived from audited
     financial statements of the Company for the periods
     specified in such letter, as indicated in their reports
     thereon, copies of which have been furnished to the Agents;

        (iii) The unaudited selected financial information with
     respect to the consolidated results of operations and
     financial position of the Company for the five most recent
     fiscal years included in the Prospectus and included or
     incorporated by reference in Item 6 of the Company's Annual
     Report on Form 10-K for the most recent fiscal year agrees
     with the corresponding amounts (after restatement where
     applicable) in the audited consolidated financial statements
     for five such fiscal years which were included or
     incorporated by reference in the Company's Annual Reports on
     Form 10-K for such fiscal years;

         (iv) On the basis of limited procedures, not
     constituting an audit in accordance with generally accepted
     auditing standards, consisting of a reading of the unaudited
     financial statements and other information referred to
     below, a reading of the latest available interim financial

     statements of the Company and its subsidiaries, inspection
     of the minute books of the Company and its subsidiaries
     since the date of the latest audited financial statements
     included or incorporated by reference in the Prospectus,
     inquiries of officials of the Company and its subsidiaries
     responsible for financial and accounting matters and such
     other inquiries and procedures as may be specified in such
     letter, nothing came to their attention that caused them to
     believe that:

               (A) the unaudited condensed consolidated
          statements of income, consolidated balance sheets and
          consolidated statements of cash flows included or
          incorporated by reference in the Company's Quarterly
          Reports on Form 10-Q incorporated by reference in the

          respects with the applicable accounting requirements of
          the Exchange Act as it applies to Form 10-Q and the
          related published rules and regulations thereunder or
          are not in conformity with generally accepted
          accounting principles applied on a basis substantially
          consistent with the basis for the audited consolidated
          statements of income, consolidated balance sheets and
          consolidated statements of cash flows included or
          incorporated by reference in the Company's Annual
          Report on Form 10-K for the most recent fiscal year;

               (B) any other unaudited income statement data and
          balance sheet items included in the Prospectus do not
          agree with the corresponding items in the unaudited
          consolidated financial statements from which such data
          and items were derived, and any such unaudited data and
          items were not determined on a basis substantially
          consistent with the basis for the corresponding amounts
          in the audited consolidated financial statements
          included or incorporated by reference in the Company's
          Annual Report on Form 10-K for the most recent fiscal
          year;

               (C) the unaudited financial statements which were
          not included in the Prospectus but from which were
          derived the unaudited condensed financial statements
          referred to in clause (A) above and any unaudited
          income statement data and balance sheet items included
          in the Prospectus and referred to in Clause (B) above
          were not determined on a basis substantially consistent
          with the basis for the audited financial statements
          included or incorporated by reference in the Company's
          Annual Report on Form 10-K for the most recent fiscal

          financial statements included or incorporated by
          reference in the Prospectus do not comply as to form in
          all material respects with the applicable accounting
          requirements of the Act and the published rules and
          regulations thereunder or the pro forma adjustments
          have not been properly applied to the historical
          amounts in the compilation of those statements;

               (E) as of the specified date not more than five
          business days prior to the date of such letter, there
          have been any changes in the consolidated capital stock
          (other than issuances of capital stock upon exercise of
          options and stock appreciation rights, upon earn-outs

          long-term debt of the Company and its subsidiaries, or
          any decreases in consolidated net assets or other items
          specified by the Agents, or any increases in any items
          specified by the Agents, in each case as compared with
          amounts shown in the latest balance sheet included or
          incorporated by reference in the Prospectus, except in
          each case for changes, increases or decreases which the
          Prospectus discloses have occurred or may occur or
          which are described in such letter; and

               (F) for the period from the date of the latest
          financial statements included or incorporated by
          reference in the Prospectus to the specified date
          referred to in Clause (E) above there were any
          decreases in consolidated revenues or any material
          decreases in the total or per share amounts or
          consolidated net income or other items specified by the
          Agents, or any increases in any items specified by the
          Agents, in each case as compared with the comparable
          period of the preceding year and with any other period
          of corresponding length specified by the Agents, except
          in each case for increases or decreases which the
          Prospectus discloses have occurred or may occur or
          which are described in such letter; and

          (v) In addition to the audit referred to in their
     report(s) included or incorporated by reference in the
     Prospectus and the limited procedures, inspection of minute
     books, inquiries and other procedures referred to in
     paragraphs (iii) and (iv) above, they have carried out
     certain specified procedures, not constituting an audit in
     accordance with generally accepted auditing standards, with

     respect to certain amounts, percentages and financial
     information specified by the Agents, which are derived from
     the general accounting records of the Company and its
     subsidiaries, which appear in the Prospectus (excluding
     documents incorporated by reference), or in Part II of, or
     in exhibits and schedules to, the Registration Statement
     specified by the Agents or in documents incorporated by
     reference in the Prospectus specified by the Agents, and
     have compared certain of such amounts, percentages and
     financial information with the accounting records of the
     Company and its subsidiaries and have found them to be in
     agreement.

ferred Stock or upon exercise of Warrants for such securities, including such 
shares of Common Stock and Preferred Stock as may be issued pursuant to 
anti-dilution adjustments, in amounts, at prices and on terms to be 
determined at the time of offering (the "Indeterminate Securities").  
Pursuant to Rule 429 under the Securities Act, the prospectus included in the 
Registration Statement also relates to $95,500,000 of securities (the 
"Registered Securities") registered as Debt Securities, Preferred Stock, 
Common Stock, Warrants and Indeterminate Securities under Registration 
Statement No. 33-69132 (the "Prior Registration Statement").  The Debt 
Securities, Preferred Stock, Common Stock, Warrants, Indeterminate 
Securities, Registered Securities and any additional securities of the 
Company which are registered in a registration statement filed pursuant to 
Rule 462(b) under the Securities Act (a "Rule 462(b) Registration Statement") 
are collectively referred to herein as the "Securities."  The Senior Debt 
Securities may be issued under an Indenture, dated as of September 15, 1990 
(the "Senior Indenture"), between the Company and The Chase Manhattan Bank, 
N.A., as trustee (the "Senior Indenture Trustee").  The Subordinated Debt 
Securities may be issued under an Indenture, dated as of May 1, 1995 (the 
"Subordinated Indenture" and, together with the Senior Indenture, the 
"Indentures"), between the Company and Mellon Bank, N.A., as trustee (the 
"Subordinated Indenture Trustee" and, together with the Senior Indenture 
Trustee, the "Trustees").

          This opinion is delivered in accordance with the requirements of Item
601(b)(5) of Regulation S-K under the Securities Act.

          We have examined (i) the form of Registration Statement; (ii) the 
Prior Registration Statement; (iii) the Senior Indenture; (iv) the 
Subordinated Indenture; (v) the form of underwriting agreement that may be 
entered into between the Company and Goldman, Sachs & Co. or another 
underwriter or underwriters in connection with

any offering of the Securities (the "Underwriting Agreement"); (vi) the
Certificate of Incorporation of the Company, as amended to the date hereof;
(vii) the By-laws of the Company as currently in effect; (viii) a specimen of
the share certificate used to represent shares of the Common Stock; (ix) certain
resolutions adopted by the Board of Directors of the Company (the "Board")
relating to the issuance of the Securities (the "Board Resolutions"); and
(x) the order of the Commission dated October 9, 1990 declaring the Senior
Indenture qualified under the Trust Indenture Act of 1939, as amended (the
"Trust Indenture Act"), and the order of the Commission dated October 8, 1993
declaring the Prior Registration Statement effective under the Securities Act
and the Subordinated Indenture qualified under the Trust Indenture Act.  We have
also examined originals or copies, certified or otherwise identified to our
satisfaction, of such records of the Company and such agreements, certificates
of public officials, certificates of officers or other representatives of the
Company and others, and such other documents, certificates and records as we
have deemed necessary or appropriate as a basis for the opinions set forth
herein.

          In our examination, we have assumed the legal capacity of all natural
persons, the genuineness of all signatures, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified, conformed or photostatic copies and the
authenticity of the originals of such latter documents.  In making our
examination of documents executed or to be executed by parties other than the
Company, we have assumed that such parties had the power, corporate or other, to
enter into and perform all obligations thereunder and have also assumed the due
authorization by all requisite action, corporate or other, and execution and
delivery by such parties of such documents and the validity and binding effect
thereof.  We have also assumed that the stock certificates evidencing the shares
of Common Stock to be issued will conform

to the specimen thereof examined by us.  As to any facts material to the
opinions expressed herein which were not independently established or verified,
we have relied upon oral or written statements and representations of officers
and other representatives of the Company and others.

          Members of our firm are admitted to the Bar in the States of New York
and Delaware, and we do not express any opinion as to the laws of any other
jurisdiction other than the laws of the United States of America to the extent
referred to specifically herein.  The Securities may be issued from time to time
on a delayed or continuous basis, and this opinion is limited to the laws,
including the rules and regulations, as in effect on the date hereof.

          Based upon and subject to the foregoing, we are of the opinion that:

          1.  With respect to any series of Debt Securities (the "Offered 
Debt Securities"), when (i) the Registration Statement, as finally amended 
(including all necessary post-effective amendments and any Rule 462(b) 
Registration Statement), has become effective; (ii) an appropriate Prospectus 
Supplement with respect to the Offered Debt Securities has been prepared, 
delivered and filed in compliance with the Securities Act and the applicable 
rules and regulations thereunder; (iii) if the Offered Debt Securities are to 
be sold pursuant to a firm commitment underwritten offering, the Underwriting 
Agreement with respect to the Offered Debt Securities has been duly 
authorized, executed and delivered by the Company and the other parties 
thereto; (iv) the Board, including any appropriate committee appointed 
thereby, and appropriate officers of the Company have taken all necessary 
corporate action to approve the issuance and terms of the Offered Debt 
Securities and related matters; (v) the terms of the Offered Debt Securities 
and of their issuance and sale have been duly established in conformity

<PAGE>

with the applicable Indenture so as not to violate any applicable law, the
Certificate of Incorporation or By-laws of the Company or result in a default
under or breach of any agreement or instrument binding upon the Company and so
as to comply with any requirement or restriction imposed by any court or
governmental body having jurisdiction over the Company; (vi) the Offered Debt
Securities have been duly executed and authenticated in accordance with the
provisions of the applicable Indenture and duly delivered to the purchasers
thereof upon payment of the agreed-upon consideration therefor, (1) the Offered
Debt Securities (including any Debt Securities duly issued upon exercise of any
Warrants in accordance with the terms thereof), when issued and sold in
accordance with the applicable Indenture and the Underwriting Agreement or any
other duly authorized, executed and delivered applicable valid and binding
purchase or distribution agreement (or upon exercise of the Warrants), will be
valid and binding obligations of the Company, enforceable against the Company in
accordance with their respective terms, except to the extent that enforcement
thereof may be limited by (a) bankruptcy, insolvency, reorganization, fraudulent
transfer, moratorium or other similar laws now or hereafter in effect relating
to creditors' rights generally, (b) general principles of equity (regardless of
whether enforceability is considered in a proceeding at law or in equity), (c)
public policy considerations which may limit the rights of parties to obtain
further remedies, (d) requirements that a claim with respect to any Offered Debt
Securities denominated other than in United States dollars (or a judgment
denominated other than in United States dollars in respect of such claim) be
converted into United States dollars at a rate of exchange prevailing on a date
determined pursuant to applicable law, (e) governmental authority to limit,
delay or prohibit the making of payments outside the United States or in foreign
currencies, currency units or composite currencies; and (2) if Common Stock or
Preferred Stock is issuable upon conversion or exchange of any convertible
Offered

<PAGE>

UNUM Corporation

Page 6


Debt Securities, the Common Stock or Preferred Stock issuable upon conversion or
exchange of such Offered Debt Securities will be validly issued, fully paid and
nonassessable, assuming the conversion or exchange of the Offered Debt
Securities in accordance with the terms of the applicable Indenture relating
thereto.

          We note that, as of the date of this opinion, a judgment for money in
an action based on a Debt Security denominated in a foreign currency, currency
unit or composite currency in a federal or state court in the United States
ordinarily would be enforced in the United States only in United States dollars.
The date used to determine the rate of conversion of the foreign currency,
currency unit or composite currency in which a particular Debt Security is
denominated into United States dollars will depend upon various factors,
including which court renders the judgment.

          2.  With respect to the shares of any series of Preferred Stock 
(the "Offered Preferred Stock"), when (i) the Registration Statement, as 
finally amended (including all necessary post-effective amendments and any 
Rule 462(b) Registration Statement), has become effective; (ii) an 
appropriate Prospectus Supplement with respect to the shares of the Offered 
Preferred Stock has been prepared, delivered and filed in compliance with the 
Securities Act and the applicable rules and regulations thereunder; (iii) if 
the Offered Preferred Stock is to be sold pursuant to a firm commitment 
underwritten offering, the Underwriting Agreement with respect to the shares 
of the Offered Preferred Stock has been duly authorized, executed and 
delivered by the Company and the other parties thereto; (iv) the Board, 
including any appropriate committee appointed thereby, and appropriate 
officers of the Company have taken all necessary corporate action to approve 
the issuance and terms of the shares of the Offered Preferred Stock and 
related matters, including the adoption of a Certificate of Designation for 
the Offered Preferred Stock in accordance with the applicable

Delaware has duly occurred; (vi) the terms of the Offered Preferred Stock and of
their issuance and sale have been duly established in conformity with the
Company's Certificate of Incorporation including the Certificate of Designation
relating to the Offered Preferred Stock and the By-laws of the Company so as not
to violate any applicable law, the Certificate of Incorporation or By-laws of
the Company or result in a default under or breach of any agreement or
instrument binding upon the Company and so as to comply with any requirement or
restriction imposed by any court or governmental body having jurisdiction over
the Company; and (vii) certificates representing the shares of the Offered
Preferred Stock are duly established in accordance with the applicable 
provisions of Delaware law and are duly executed, countersigned, 
registered and delivered upon payment of the agreed-upon consideration therefor,
(1) the shares of the Offered Preferred Stock (including any Preferred Stock
duly issued upon exercise of any Warrants in accordance with the terms thereof),
when issued and sold in accordance with the Underwriting Agreement or any other
duly authorized, executed and delivered applicable valid and binding purchase or
distribution agreement (or upon exercise of the Warrants), will be duly
authorized, validly issued, fully paid and nonassessable, provided that the
consideration therefor is not less than the par value thereof; and (2) if the
Offered Preferred Stock is convertible or exchangeable into Common Stock, the
Common Stock issuable upon conversion or exchange of the Offered Preferred Stock
will be duly authorized, validly issued, fully paid and nonassessable, assuming
the conversion or exchange of the Offered Preferred Stock in accordance with the
terms of the Certificate of Designation.

          3.  With respect to any offering of Common Stock, when (i) the
Registration Statement, as finally amended (including all necessary post-

By-laws so as not to violate any applicable law, the Certificate of

Registration Statement), has become effective; (ii) an
