THE COMPANY
 
    Protective  Life Corporation  ("Protective Life" or  the "Company"), through
its subsidiary life  insurance companies, produces,  distributes and services  a
diverse  array  of insurance  and investment  products. Protective  Life markets
individual life insurance,  dental insurance, group  life and health  insurance,
credit  life  and  disability  insurance,  guaranteed  investment  contracts and
annuities throughout the United  States. The Company  also maintains a  separate
line  of business devoted  exclusively to the  acquisition of insurance policies
from other  companies. The  Company  recently began  to market  individual  life
insurance  in Hong  Kong through  a fifty-percent-owned  joint venture  with the
Lippo Group. Protective  Life Insurance Company  ("Protective Life  Insurance"),
founded in 1907, is Protective Life's principal operating subsidiary. Unless the
context  otherwise requires, as  used in this  Prospectus Supplement "Protective
Life"  and  "Company"  refer  to  the  consolidated  group  of  Protective  Life
Corporation  and its subsidiaries. Protective  Life Insurance is currently rated
A+ (Superior) by A.M. Best  Company, Inc. Protective Life's principal  executive
offices  are  located  at  2801 Highway  280  South,  Birmingham,  Alabama 35223
(Telephone: (205) 879-9230).
 
    For the year ended December 31,  1995, Protective Life reported revenues  of
$922  million and net income of $76.7  million. For the three months ended March
31, 1996, Protective Life  reported revenues of $250  million and net income  of
$21.1  million. At  March 31,  1996, Protective  Life had  total assets  of $7.6
billion, stockholders' equity  of $491 million  and life insurance  in force  of
$65.9 billion.
 
    Over  the five year period ended  December 31, 1995, Protective Life's total
assets have grown from  $2.3 billion to $7.2  billion, a compound annual  growth
rate  of 25%.  In the  same five-year period,  Protective Life's  net income has
grown from $28.1 million to $76.7 million, a compound annual growth rate of 22%,
and its return on equity has averaged 17.4%.
 
STRATEGY
 
    The Company's operating strategy has  been to identify market  opportunities
in  the life and  health insurance business that  offer attractive prospects for
growth and profitability  and then to  move quickly to  take advantage of  those
opportunities  and become a  strong participant in  the targeted market segment.
The Company  believes that  its diverse  product mix  supports the  strategy  by
giving  the Company broad exposure to attractive market opportunities and a more
diverse base  of  earnings.  The  Company  also  emphasizes  discipline  in  the
allocation of capital, the pricing of products and the management of expenses.
 
    Protective  Life is  organized around six  primary divisions,  which are the
Acquisitions  Division,  the  Guaranteed  Investment  Contracts  Division,   the
Individual  Life Insurance Division, the Group Division, the Investment Products
Division and the Financial Institutions Division.

1.  Information  for the  three-month periods ended  March 31, 1996  and 1995 is
    unaudited but, in the opinion of management, all adjustments (consisting  of
    normal  recurring  accruals) necessary  for  a fair  presentation  have been
    included. Operating results for the three-month period ended March 31,  1996
    are  not necessarily indicative of the results  that may be expected for the
    year ending December 31, 1996.
 
2.  The selected financial  data for the  years ended December  31, 1995,  1994,
    1993,  1992 and 1991  has been derived  from previously audited consolidated
    financial statements of Protective Life.
 
3.  Income before Income Tax excluding realized investment gains and losses  and
    related amortization of deferred policy acquisition costs.
 
4.  Certain  reclassifications have been made in the previously reported results
    relating to  the  allocation of  corporate  overhead to  make  prior  period
    results  comparable to those of the current year. Such reclassifications had
    no effect on previously reported net income, total assets, or  stockholders'
    equity.
 
5.  In  1993 Protective Life changed the method used to apportion net investment
    income within  Protective  Life. The  change  resulted in  increased  income
    attributable  to the Acquisitions, Individual Life Insurance, and Investment
    Products business  segments  of  approximately $2,600,  $3,000  and  $2,000,
    respectively, while decreasing income of the Corporate and Other segment.
 
6.  Pre-tax  income for the Guaranteed Investment Contracts business segment has
    not been reduced  by pre-tax minority  interest of $1,631  in 1991.  Pre-tax
    income  for the Corporate and Other business segment has not been reduced by
    pre-tax minority interest of $4,950 in 1995, $2,764 in 1994, $19 in 1993 and
    $90 in 1992 and 1991, and $1,238 and $1,237 in the three months ending March
    31, 1996 and 1995,  respectively. Such minority interest  in 1996, 1995  and
    1994 arises from payments made on Monthly Income Preferred Securities issued
    in 1994.
 
ACQUISITIONS DIVISION
 
    Protective  Life is an  active participant in the  consolidation of the life
and health insurance industry. The  Acquisitions Division has approximately  120
full-time  employees and focuses  solely on acquiring,  converting and servicing
business acquired from  other companies.  The Company  has long  been an  active
acquiror  of  blocks  of  insurance  policies  and  has  closed  a  total  of 35
acquisitions over the last 25 years. In 1990, the Company became more focused on
the acquisitions business and, since that  year, has invested over $170  million
in  acquired blocks of policies and  small insurance companies. In the five-year
period ended  December 31,  1995, pretax  operating earnings  from  acquisitions
increased  from $17.6 million to $48.5 million, a compound annual growth rate of
22%. The Division concentrates on  identifying acquisition opportunities in  the
$10  million to $50 million range, a market segment that the Company believes to
be less competitive  than the  market for larger  transactions. Protective  Life
believes  that its highly  focused and disciplined  approach to the acquisitions
process and  its  extensive experience  in  the assimilation,  conservation  and
servicing  of  purchased books  of business  give  it a  significant competitive
advantage over many other companies  that attempt to make similar  acquisitions.
The Company expects acquisition opportunities to continue to be available as the
life insurance industry continues to consolidate.
 
GUARANTEED INVESTMENT CONTRACTS DIVISION
 
    Protective  Life's Guaranteed Investment Contracts  Division markets GICs to
401(k) and other qualified  retirement savings plans.  The Division also  offers
guaranteed  funding agreements  to the trustees  of municipal  bond proceeds and
other annuity contracts. Protective  Life entered the GIC  business in 1989.  In
the  five-year period ended December 31, 1995, the Division's operating earnings
increased from $4.3 million  to $31.6 million. The  Division's emphasis is on  a
consistent  and  disciplined  approach to  product  pricing  and asset/liability
management, careful underwriting of early  withdrawal risks and maintaining  low
distribution and administration costs.

INDIVIDUAL LIFE INSURANCE DIVISION
 
    The  Individual  Life Insurance  Division markets  universal and  other life
insurance products on a national basis.  In the five-year period ended  December
31,  1995, the  Division's sales  (as measured  by new  annualized premium) have
grown from $17.9 million to $36.3 million, a compound annual growth rate of 15%.
Over the same period, the U.S. life insurance industry has experienced virtually
no growth  in annualized  new premium  sales. The  Division's primary  marketing
channel  is a network of independent insurance agents. In addition, the Division
has grown sales by developing niche marketing strategies. The strategies include
marketing  specialty   products  through   insurance  brokerage   channels   and
traditional life insurance products through regional stock brokers. The Division
has  also developed a unit  to distribute life insurance  products on a "private
label" basis through other insurance companies.
 
GROUP DIVISION
 
    The Group Division's strategic emphasis is on a full range of indemnity  and
managed-care  dental products. At March 31,  1996, the Company had approximately
351,000 members in its dental  HMOs and over 768,000  lives covered in total  by
its dental programs.
 
    The Group Division was a pioneer in developing indemnity dental products for
the voluntary payroll deduction market. In the first quarter of 1995, Protective
Life  entered the dental managed care segment  when it acquired a dental managed
care company  which transacts  business under  the trade  name "DentiCare".  The
acquisition  combined DentiCare's high quality  service and product capabilities
with the Group Division's marketing  strength and capacity to distribute  dental
products   through  a  much  broader   geographic  distribution  framework.  The
Division's strategy is to promote a "dual choice" option by offering DentiCare's
products  through  Protective  Life's  existing  indemnity  dental  distribution
channels.  The Division has  developed an innovative  system for prospecting and
selling dental insurance products by telephone. The Division also plans to  grow
the  dental business  through acquisitions.  In the  first quarter  of 1996, the
Division extended the  geographic reach  of its dental  managed care  operations
into  Oklahoma,  Arkansas  and  Missouri,  and  added  approximately  38,000 new
members, through the acquisition of two dental managed care plans licensed to do
business in  those  states. The  Company's  dental annualized  new  premium  and
premium  equivalent sales were $13.6 million in  1994 and $27.0 million in 1995,
an increase of 99%. For the quarter  ended March 31, 1996 the Company had  $14.4
million of such sales.
 
    The  Group  Division  also actively  markets  group life,  group  health and
disability coverages, typically  to employee  groups of 25  to 100,  as well  as
administrative  services for  self-insured employer  health plans.  The Division
also markets cancer insurance, but is  currently evaluating whether to sell  its
existing cancer book of business.
 
INVESTMENT PRODUCTS DIVISION
 
    The   Investment  Products  Division  markets  fixed  and  variable  annuity
products. Annuity  products are  primarily  used by  consumers  as a  source  of
retirement  savings. Overall  industry sales of  annuity products  have grown in
recent years as the "baby-boom" generation has increased its level of retirement
savings. The  Division's  annuity  products  are  sold  through  broker-dealers,
financial  institutions and the Individual Life Insurance Division's agent sales
force. The Company's primary  product is a variable  annuity that offers  mutual
funds  managed by  Goldman, Sachs  & Co.  The Division  has been  marketing this
product for 27 months. The variable annuity account balance was $456 million  at
March 31, 1996.
 
FINANCIAL INSTITUTIONS DIVISION
 
    The  Company's  Financial  Institutions  Division  specializes  in marketing
credit life and credit disability  insurance products through commercial  banks,
savings  and  loan associations,  mortgage bankers  and automobile  dealers. The
majority of these policies cover  consumer loans made by financial  institutions
located  primarily  in the  southeastern  United States  and  automobile dealers
throughout the  United  States.  The Division  markets  through  employee  field
representatives,  independent  brokers  and a  wholly-owned  subsidiary.  In the
five-year period ended December  31, 1995, the  Division's sales have  increased
from  $45 million  to $135 million,  a compound  annual growth rate  of 25%. The
Company believes it has
 
                                      S-6
<PAGE>
been a  beneficiary of  a  "flight to  quality"  as financial  institutions  and
automobile  dealers  increasingly prefer  to  do business  with  insurers having
quality products, strong  balance sheets and  high-quality training and  service
capabilities.
 
CORPORATE AND OTHER
 
    The  Corporate and  Other segment  consists of  earnings from  the Company's
fifty-percent-owned joint venture in Hong Kong with the Lippo Group, unallocated
net investment income on  capital, interest expense  on substantially all  debt,
charitable   contributions,  and  earnings  from  several  small  insurance  and
noninsurance subsidiaries such as the Company's recent investment in a 30% stake
in QuickQuote, an  Internet-based insurance  distribution system.  In 1995,  its
first  year of operations, the Hong Kong joint venture company, Lippo Protective
Life Insurance Company,  had annualized new  premium sales of  $5.9 million  and
$2.2 million in the first quarter of 1996.
 
INVESTMENT PORTFOLIO
 
    Protective  Life believes its investment strategy  is a key component of its
financial  success.  The  Company   targets  three  primary  asset   categories:
mortgage-backed  securities, corporate bonds and bank loan participations, and a
specialized class  of  commercial  mortgage loans.  The  portfolio  is  actively
managed  to  support the  liabilities of  Protective  Life's lines  of business,
giving consideration to  such factors  as liquidity  needs, investment  quality,
investment  return, matching of  assets and liabilities,  and the composition of
the portfolio by asset type and  credit exposure. The following table shows  the
composition of Protective Life's invested assets at March 31, 1996:

</TABLE>
 
    In  its mortgage-backed securities portfolio, Protective Life has focused on
sequential and  planned amortization  class securities,  which tend  to be  less
volatile  than  other  classes  of  mortgage-backed  securities,  and  on strict
underwriting and  constant  monitoring  of  the portfolio  through  the  use  of
state-of-the-art  technology. Almost  all of  the Company's  corporate bonds are
investment grade,  publicly traded  securities. The  Company's participation  in
senior  bank loan programs  provides it with enhanced  yields and flexibility in
matching maturities in its GIC portfolio. Bank loan participations totalled $216
million at March 31, 1996.
 
    In its approach to commercial mortgage loans, the Company has, for 25 years,
specialized in originating small (average new  loan size of $2.4 million)  loans
to  finance  shopping centers,  typically  in smaller  communities.  The Company
provides a  high level  of service  to  the developers  of such  properties  and
generally does not attempt to compete for business solely by offering the lowest
interest  rates available. Such  loans provide attractive  yields to the Company
and historically have performed  very well. On a  cumulative basis, the  Company
has  had  no  significant loss  of  principal  on its  commercial  mortgage loan
portfolio over the last 20 years. As  of March 31, 1996, 2.3% of the  commercial
loan  portfolio was classified as 90  days past due, foreclosed or restructured,
which the Company believes to be well below
 
                                      S-7
<PAGE>
the life insurance industry average. The Company believes that its many years of
specialization in  this subsegment  of  the real  estate  industry helps  it  to
maintain the quality of its loan underwriting and loan approval process.
 
                           INVESTMENT CONSIDERATIONS
 
    Set  forth below  is a discussion  of certain considerations  relevant to an
investment in  the Common  Stock. For  additional information  concerning  these
considerations   and  other  factors   relevant  to  such   an  investment,  see
"Management's Discussion  and Analysis  of Financial  Condition and  Results  of
Operations  -- Results of Operations -- Known Trends and Uncertainties" included
in Protective Life's 1995 Annual Report  and incorporated by reference into  its
Form 10-K Report for the year ended December 31, 1995.
 
COMPETITION
 
    Life  insurance  is  a  highly  competitive  industry  and  Protective  Life
encounters significant competition in all lines of business from other insurance
companies, many of which have greater financial resources than Protective  Life,
as well as competition from other providers of financial services.
 
RATINGS
 
    Ratings  are an  important factor in  the competitive  position of insurance
companies. Rating organizations  periodically review  the financial  performance
and   condition  of  insurers,  including  Protective  Life  and  its  insurance
subsidiaries. A downgrade in the ratings of Protective Life's subsidiaries could
adversely affect its ability to sell its products and its ability to compete for
attractive acquisition opportunities.
 
LIQUIDITY OF INVESTMENT PORTFOLIO
 
    Many of the  products offered  by Protective  Life's insurance  subsidiaries
allow  policyholders and contractholders  to withdraw their  funds under defined
circumstances. Protective  Life's  insurance subsidiaries  design  products  and
configure  investment  portfolios  so  as  to  provide  and  maintain sufficient
liquidity to support  anticipated withdrawal demands  and contract benefits  and
maturities.  Formal asset/ liability  programs are used  continuously to monitor
the relative duration of the Company's assets and liabilities. While  Protective
Life's insurance subsidiaries own a significant amount of liquid assets, many of
their  assets are  relatively illiquid. Significant  unanticipated withdrawal or
surrender activity  could, under  some circumstances,  compel Protective  Life's
insurance subsidiaries to dispose of illiquid assets on unfavorable terms, which
could have a material adverse effect on Protective Life.
 
INTEREST RATE FLUCTUATIONS
 
    Sudden changes in interest rates expose life insurance companies to the risk
of not earning anticipated spreads between the returns earned on investments and
the  credited  rates paid  on outstanding  policies.  Both rising  and declining
interest  rates  can  negatively  affect  the  Company's  spread  income.  While
Protective  Life maintains  programs and  procedures designed  to protect spread
income in rising  or falling  interest rate  environments, no  assurance can  be
given that significant changes in interest rates will not materially affect such
spreads.
 
REGULATION AND TAXATION
 
    Protective   Life's  insurance   subsidiaries  are   subject  to  government
regulation in each of the states in which they conduct business. Such regulation
is vested in state agencies having  broad administrative power over all  aspects
of  the  insurance  business,  including  premium  rates,  marketing  practices,
advertising, policy forms and capital adequacy, and is concerned primarily  with
the protection of policyholders rather than stockholders. Protective Life cannot
predict the form of any future regulatory initiatives.
 
    Under the Internal Revenue Code of 1986, as amended (the "Code"), income tax
payable   by  policyholders  on  investment  earnings  is  deferred  during  the
accumulation period  of  certain  life  insurance  and  annuity  products.  This
favorable  tax  treatment  may  give certain  of  Protective  Life's  products a
competitive advantage over other non-insurance products. To the extent that  the
Code is revised to
 
                                      S-8
<PAGE>
reduce  the tax-deferred  status of life  insurance and annuity  products, or to
increase the  tax deferred  status  of competing  products, all  life  insurance
companies, including Protective Life, would be adversely affected.
 
LITIGATION
 
    A  substantial number of civil jury verdicts have been returned against life
and health insurers in the jurisdictions in which Protective Life does  business
involving  the insurers' sales  practices, alleged agent  misconduct, failure to
properly supervise agents, and other  matters. Increasingly these lawsuits  have
resulted  in the award  of substantial judgments  against the insurer, including
material amounts of  punitive damages  that are disproportionate  to the  actual
damages.  In some states (including Alabama), juries have substantial discretion
in awarding  punitive  damages which  creates  the potential  for  unpredictable
material  adverse judgments in any given  punitive damages suit. Protective Life
and its  subsidiaries, like  other life  and health  insurers, in  the  ordinary
course  of business are involved in such  litigation. In addition, in some class
action and other  lawsuits involving  insurers' sales  practices, insurers  have
made material settlement payments. Although the outcome of any litigation cannot
be  predicted with certainty, the management of Protective Life believes that at
the present time there are no pending or threatened lawsuits that are reasonably
likely to have a material adverse effect on the Company's financial condition.
 
INVESTMENT RISKS
 
    Protective Life's invested assets are  subject to customary risks of  credit
defaults  and changes  in market values.  The value of  the Company's commercial
mortgage portfolio  depends  in part  on  the creditworthiness  of  the  tenants
occupying the properties which the Company has financed. Factors that may affect
the  overall default rate on, and market value of, the Company's invested assets
include interest rate levels, financial market performance and general  economic
conditions,  as  well as  particular circumstances  affecting the  businesses of
individual borrowers and tenants.

blocks  of insurance policies  or otherwise support the  continued growth of the
business.

1.  Certain  reclassifications have been made in the previously reported results
    to make prior period results comparable  to those of the current year.  Such
    reclassifications  had no  effect on  previously reported  net income, total
    assets, or stockholders' equity.

3.  Reflects   the  adoption  of  SFAS   No.  106,  "Employers'  Accounting  For
    Postretirement Benefits  Other Than  Pensions," which  decreased net  income

4.  Reflects  the adoption of SFAS No.  115, "Accounting for Certain Investments
    in Debt and Equity Securities" at  December 31, 1993. As prescribed by  SFAS
    No.  115, certain investments  are recorded at their  market values with the
    resulting unrealized gains  and losses  reduced by a  related adjustment  to
    deferred  policy  acquisition  costs,  net  of  income  tax,  reported  as a
    component of stockholders'  equity. The  market values  of fixed  maturities
    increase or decrease as interest rates fall or rise. Therefore, although the
    adoption  of  SFAS No.  115 does  not affect  the Company's  operations, its
    reported stockholders' equity will fluctuate significantly as interest rates
    change.

8.  Of Protective  Life's insurance  subsidiaries  prepared in  conformity  with
    statutory   accounting  practices  prescribed   or  permitted  by  insurance
    regulatory  authorities.  Statutory  accounting  practices  differ  in  some
    respects  from generally  accepted accounting  principles. For  example, (a)
    acquisition costs of obtaining new businesses are expensed as incurred,  (b)
    benefit  liabilities are computed using methods statutorily mandated and are
    not adjusted for actual experience, (c)  income tax expenses is computed  on
    taxable  earnings and (d) furniture and equipment, agents' debt balances and
    prepaid expenses are charged directly  against surplus rather than  reported
    as assets.

    Protective Life (or its predecessor) has paid cash dividends each year since
1926 and each  quarter since 1934.  Protective Life expects  to continue to  pay
cash  dividends, subject to  the earnings and  financial condition of Protective
Life and other  relevant factors.  The ability of  Protective Life  to pay  cash
dividends  is  dependent  on  cash  dividends  and  other  payments  received by
Protective Life  from  its life  insurance  subsidiaries which  are  subject  to
certain limitations under applicable insurance laws and financial covenants.

                         ------------------------------
 
    Protective Life Corporation, a Delaware corporation ("Protective Life"), may
from time to time offer (a) its debt securities, (the "Debt Securities"), in one
or  more series, which  may be either  senior debt securities  (the "Senior Debt
Securities")  or   subordinated   debt  securities   (the   "Subordinated   Debt
Securities"),  (b)  shares of  its preferred  stock, par  value $1.00  per share
("Preferred Stock"), in  one or  more series, and/or  (c) shares  of its  common
stock,  par value $.50 per share ("Common Stock"), and PLC Capital, a subsidiary
of Protective Life ("PLC Capital"), may from time to time offer, in one or  more
series,  its  Cumulative  Monthly Income  Preferred  Securities  (the "Preferred
Securities"), in each case in amounts, at  prices and on terms to be  determined
at  the time or times of offering.  The Debt Securities, Preferred Stock, Common
Stock and  Preferred  Securities are  referred  to herein  collectively  as  the
"Offered  Securities".  The  aggregate  initial offering  price  of  the Offered
Securities in  respect of  which this  Prospectus is  being delivered  will  not
exceed  U.S. $120,000,000 (or  its equivalent (based  on the applicable exchange
rate at the time of issue), in one or more foreign currencies or currency  units
as shall be designated by Protective Life). The aggregate initial offering price

common  limited liability company  interests ("Common Securities")  and loan the
proceeds thereof to Protective Life. Accordingly, the proceeds of an offering of
Preferred Securities, together with all capital contributions made in respect of
Common  Securities,  will  be  loaned   to  Protective  Life  in  exchange   for
Subordinated  Debt  Securities  of Protective  Life  ("Subordinated Debentures")
having the  terms  described herein.  Interest  and principal  payments  on  the
Subordinated   Debentures  are  intended   to  fund  the   payment  of  periodic
distributions ("dividends") and redemption and liquidation distributions on  the
Preferred  Securities and the  Common Securities. The  payment of dividends (but
only if and to the extent declared out of moneys held by PLC Capital and legally
available therefor), and payments on liquidation (but only to the extent of  the
remaining  assets of PLC  Capital) or redemption  at the option  of PLC Capital,
with respect to the  Preferred Securities will be  guaranteed by a  subordinated
guarantee  (the "Guarantee") of Protective Life  to the extent set forth herein.
See "PLC  Capital  L.L.C."  and  "Description  of  Certain  Contractual  Back-Up
Obligations  of Protective  Life" for a  description of  the various contractual
backup obligations of Protective Life.

other  unsecured  and  unsubordinated  indebtedness  of  Protective  Life.   The
Subordinated  Debt Securities  will be subordinated  in right of  payment to all

described  herein  and in  the Prospectus  Supplement relating  thereto.The Debt
Securities may be  denominated in  United States dollars  or, at  the option  of

Prospectus Supplement, Debt Securities of a series may be issued in whole or  in

                          PROTECTIVE LIFE CORPORATION
 
    Protective  Life,  a  Delaware  corporation  incorporated  in  1981,  is  an
insurance  holding company  that owns a  group of life  insurance companies that
provide  financial   services   through   the   production,   distribution   and
administration  of insurance and investment  products. Protective Life Insurance
Company ("Protective Life  Insurance"), founded  in 1907,  is Protective  Life's
principal operating subsidiary.
 
    Protective  Life's principal executive  offices are located  at 2801 Highway
280 South,  Birmingham,  Alabama  35223,  and  its  telephone  number  is  (205)
879-9230.
 
    Protective  Life's  ability  to  pay  principal  and  interest  on  any Debt
Securities or dividends on  any Preferred Stock or  Common Stock is affected  by
the  ability of its insurance  company subsidiaries, Protective Life's principal
sources of cash flow, to declare  and distribute dividends and to make  payments
on surplus notes (i.e., deeply subordinated intercompany notes owed by insurance
company  subsidiaries to Protective Life that  are treated as equity capital for
statutory accounting  purposes), both  of  which may  be limited  by  regulatory
restrictions and, in the case of payments on surplus notes, by certain financial
covenants.  Protective  Life's  cash flow  is  also dependent  on  revenues from
investment, data  processing,  legal and  management  services rendered  to  its
subsidiaries.  Insurance company subsidiaries of  Protective Life are subject to
various state  statutory and  regulatory restrictions,  applicable to  insurance
companies generally, that limit the amount of cash dividends, loans and advances
that  those subsidiaries may  pay to Protective  Life. Under Tennessee insurance
laws, Protective Life Insurance may  generally only pay dividends to  Protective
Life  out  of its  unassigned surplus  as reflected  in its  statutory financial
statements filed  in that  State.  In addition,  the Tennessee  Commissioner  of
Insurance  must approve (or not disapprove within  30 days of notice) payment of
an "extraordinary"  dividend from  Protective  Life Insurance,  which  generally
under  Tennessee insurance  laws is a  dividend that exceeds,  together with all
dividends paid by Protective Life Insurance  within the previous 12 months,  the
greater   of  (i)  10%  of  Protective   Life  Insurance's  surplus  as  regards
policyholders at the preceding December 31 or (ii) the net gain from  operations
of  Protective Life Insurance  for the 12  months ended on  such December 31. No
assurance can be given that more stringent restrictions will not be adopted from
time to time  by states in  which Protective Life's  insurance subsidiaries  are
domiciled,   which   restrictions   could  have   the   effect,   under  certain
circumstances, of significantly reducing dividends  or other amounts payable  to
Protective Life by such subsidiaries without affirmative prior approval by state
insurance regulatory authorities.
 
    In  the event of the insolvency, liquidation, reorganization, dissolution or
other winding-up  of a  subsidiary of  Protective Life,  all creditors  of  such
subsidiary,  including holders of  life and health  insurance policies, would be
entitled to  payment  in  full out  of  the  assets of  such  subsidiary  before
Protective Life, as shareholder or holder of surplus notes, would be entitled to
any  payment, and thus such  creditors would have to be  paid in full before the
creditors of Protective  Life (including  holders of Debt  Securities) would  be
entitled to receive any payment from the assets of such subsidiary.
 
                               PLC CAPITAL L.L.C.
 
    PLC  Capital is  a limited  liability company formed  under the  laws of the
State of Delaware. PLC Capital's offices are located at 2801 Highway 280  South,
Birmingham,  Alabama 35223  (Telephone: (205)  879-9230). Protective  Life owns,
directly   and   indirectly,   all   of    the   Common   Securities   of    PLC
 
                                       3
<PAGE>
Capital,  which Common Securities are nontransferable. PLC Capital was formed by
Protective Life and a wholly-owned subsidiary solely to issue Common  Securities
and Preferred Securities (collectively, the "Membership Securities") and to lend
the proceeds thereof to Protective Life in exchange for Subordinated Debentures.
Interest  and principal payments on Subordinated Debentures are intended to fund
the payment of  dividends and  redemption and liquidation  distributions on  the
Membership  Securities. Accordingly, PLC  Capital's sole source  of cash flow is
Protective Life, and PLC Capital's ability  to make dividend and other  payments
in  respect of Preferred Securities will  be dependent on interest and principal
payments by Protective Life on the Subordinated Debentures. See "Protective Life
Corporation".
 
    PLC Capital is managed by  Protective Life, in its  capacity as a holder  of
Common  Securities  (in  such  capacity,  the  "Managing  Member").  Holders  of
Membership Securities in PLC  Capital are referred to  herein as "Members".  PLC
Capital's  Amended and Restated Limited Liability Company Agreement (the "L.L.C.
Agreement") provides that Protective Life, in its capacity as a holder of Common
Securities, shall be liable for all  obligations and liabilities of PLC  Capital
(including  tax obligations, but  excluding obligations in  respect of Preferred
Securities). Under Delaware  law, Members who  hold Preferred Securities  (other
than  Protective  Life)  will  not  be liable  for  the  debts,  obligations and
liabilities of  PLC Capital,  whether arising  in contract,  tort or  otherwise,
solely  by reason of  being a Member  of PLC Capital  (subject to any obligation
such Members  may  have  to  repay  any funds  that  may  have  been  wrongfully
distributed to them).
 
                                USE OF PROCEEDS
 
    Except  as otherwise described in  the applicable Prospectus Supplement, the
proceeds from the sale by PLC Capital of any Preferred Securities (together with
any capital  contributed in  respect of  Common Securities)  will be  loaned  to
Protective  Life in exchange  for Subordinated Debentures.  Protective Life will
use borrowings from  PLC Capital, and  the net  proceeds from any  sale of  Debt
Securities,  Preferred Stock  or Common  Stock, for  general corporate purposes,
including, but not limited to, repayments of indebtedness of Protective Life  or
its  subsidiaries. Pending such use, the proceeds may be invested temporarily in
short-term marketable  securities. A  more detailed  description of  the use  of
proceeds  of any specific offering  of Offered Securities shall  be set forth in
the Prospectus Supplement pertaining to such offering.
 
                RATIOS OF CONSOLIDATED EARNINGS TO FIXED CHARGES
 
    The following  table sets  forth Protective  Life's ratios  of  consolidated

    If any index is used  to determine the amount  of payments of principal  of,
premium,  if any, or interest on any  series of Debt Securities, special federal
income tax,  accounting  and other  considerations  applicable thereto  will  be
described in the applicable Prospectus Supplement.
 
    The  general provisions of the Indentures do  not afford holders of the Debt
Securities protection in the  event of a highly  leveraged or other  transaction
involving  Protective  Life  that  may  adversely  affect  holders  of  the Debt
Securities.
 
PAYMENT, REGISTRATION, TRANSFER AND EXCHANGE
 
    Unless otherwise provided in the applicable Prospectus Supplement,  payments
in respect of the Debt Securities will be made in the designated currency at the
office  or agency of  Protective Life maintained for  that purpose as Protective
Life may designate from time to time,  except that, at the option of  Protective
Life,  interest payments, if any,  on Debt Securities in  registered form may be

their  registered addresses or (ii) by wire transfer to an account maintained by
the person entitled thereto as specified  in the Register. (Sections 3.7(a)  and
9.2  of each Indenture.) Unless otherwise  indicated in an applicable Prospectus
Supplement, payment  of  any  installment  of interest  on  Debt  Securities  in
registered  form will be made to the person  in whose name such Debt Security is
registered at  the  close  of business  on  the  regular record  date  for  such
interest. (Section 3.7(a) of each Indenture.)
 
    Payment  in respect of  Debt Securities in  bearer form will  be made in the
currency and in the manner designated  in the Prospectus Supplement, subject  to
any  applicable laws and regulations, at such paying agencies outside the United
States as  Protective Life  may appoint  from time  to time.  The paying  agents
outside the United States initially appointed by Protective Life for a series of
Debt  Securities will be named in the Prospectus Supplement. Protective Life may
at any time designate additional paying agents or rescind the designation of any
paying agents,  except that,  if Debt  Securities of  a series  are issuable  as
Registered Securities, Protective Life will be required to maintain at least one
paying agent in each Place of Payment for such series and, if Debt Securities of
a  series are issuable as Bearer Securities, Protective Life will be required to
maintain a paying agent in  a Place of Payment  outside the United States  where
Debt  Securities  of such  series and  any coupons  appertaining thereto  may be
presented and surrendered for payment. (Section 9.2 of each Indenture.)
 
    All moneys paid by Protective Life to the Trustee or a paying agent for  the
payment  of the principal of,  or any premium or  interest on, any Debt Security
which remain unclaimed at the end of two years after such principal, premium  or
interest  has become due and payable will  be repaid to Protective Life, and the
Holder of such Security thereafter may look only to Protective Life for  payment
thereof. (Section 9.3 of each Indenture)
 
    Unless  otherwise  provided in  the  applicable Prospectus  Supplement, Debt
Securities in registered form will be transferable or exchangeable at the agency
of Protective Life maintained for such purpose as designated by Protective  Life
from time to time. (Sections 3.5 and 9.2 of each Indenture.) Debt Securities may
be  transferred or exchanged without service charge, other than any tax or other
governmental charge  imposed  in  connection therewith.  (Section  3.5  of  each
Indenture.)
 
GLOBAL DEBT SECURITIES
 
    The  Debt Securities of  a series may be  issued in whole or  in part in the
form of one  or more fully  registered global securities  (a "Registered  Global
Security").  Each Registered Global Security will be registered in the name of a
depository (the "Depository") or a nominee for the Depository identified in  the
applicable  Prospectus  Supplement, will  be deposited  with such  Depository or
nominee  or  a  custodian  therefor  and  will  bear  a  legend  regarding   the
restrictions on exchanges and registration of transfer thereof referred to below
and any such other matters as may be provided for pursuant to each Indenture. In
such  a  case, one  or more  Registered Global  Securities will  be issued  in a
denomination or aggregate denominations  equal to the  portion of the  aggregate
principal  amount of outstanding Debt Securities of the series to be represented
by  such  Registered  Global  Security  or  Securities.  (Section  3.3  of  each
Indenture.)  Unless  and until  it is  exchanged in  whole or  in part  for Debt
Securities in definitive certificated
 
                                       7
<PAGE>
form, a Registered Global Security may not be transferred or exchanged except as
a whole by the Depository  for such Registered Global  Security to a nominee  of
such Depository or by a nominee of such Depository to such Depository or another
nominee  of  such Depository  or by  such Depository  or any  such nominee  to a
successor Depository for such series or  a nominee of such successor  Depository
and   except  in  the  circumstances  described  in  the  applicable  Prospectus
Supplement. (Section 3.5 of each Indenture.)
 
    The specific terms of the depository arrangement with respect to any portion
of a series of Debt Securities to be represented by a Registered Global Security
will be  described  in the  applicable  Prospectus Supplement.  Protective  Life
expects that the following provisions will apply to depository arrangements.
 
    Upon the issuance of any Registered Global Security, and the deposit of such
Registered  Global  Security  with  or  on behalf  of  the  Depository  for such
Registered Global  Security,  the  Depository will  credit,  on  its  book-entry
registration  and transfer system, the respective  principal amounts of the Debt
Securities represented by  such Registered  Global Security to  the accounts  of
institutions  ("participants")  that have  accounts with  the Depository  or its
nominee. The accounts to be credited  will be designated by the underwriters  or
agents  engaging in  the distribution of  such Debt Securities  or by Protective
Life, if such Debt Securities are offered and sold directly by Protective  Life.
Ownership  of  beneficial  interests in  a  Registered Global  Security  will be
limited to participants or persons that may hold interests through participants.
Ownership of  beneficial interests  by participants  in such  Registered  Global
Security will be shown on, and the transfer of such beneficial interests will be
effected  only through, records maintained by the Depository for such Registered
Global Security or  by its nominee.  Ownership of beneficial  interests in  such
Registered  Global Security  by persons that  hold through  participants will be
shown on, and the transfer of such beneficial interests within such participants
will be effected only through, records maintained by such participants. The laws
of some  jurisdictions  require  that  certain  purchasers  of  securities  take
physical  delivery  of  such  securities  in  certificated  form.  The foregoing
limitations and  such  laws  may  impair  the  ability  to  transfer  beneficial
interests in such Registered Global Securities.
 
    So  long as the Depository for a Registered Global Security, or its nominee,
is the registered owner of such  Registered Global Security, such Depository  or
such nominee, as the case may be, will be considered the sole owner or holder of
the  Debt  Securities represented  by such  Registered  Global Security  for all
purposes under each Indenture. (Section 3.8 of each Indenture.) Unless otherwise
specified in the applicable Prospectus Supplement and except as specified below,
owners of beneficial interests  in such Registered Global  Security will not  be
entitled  to have Debt  Securities of the series  represented by such Registered
Global Security registered in  their names, will not  receive or be entitled  to
receive physical delivery of Debt Securities of such series in certificated form
and  will  not be  considered the  holders  thereof for  any purposes  under the
relevant Indenture. (Section 3.5 of each Indenture.)
 
    Ownership of beneficial interests  in a Global Security  will be limited  to
participants   and  to  persons  that  may  hold  beneficial  interests  through
participants. Accordingly,  each person  owning a  beneficial interest  in  such
Registered Global Security must rely on the procedures of the Depository and, if
such  person is not a participant, on  the procedures of the participant through
which such person owns its  interest, to exercise any  rights of a holder  under
the relevant Indenture. The Depository may grant proxies and otherwise authorize
participants  to  give or  take any  request, demand,  authorization, direction,
notice, consent, waiver or other  action which a holder  is entitled to give  or
take  under  the relevant  Indenture.  Protective Life  understands  that, under
existing industry practices, if Protective  Life requests any action of  holders
or any owner of a beneficial interest in such Registered Global Security desires
to give any notice or take any action a holder is entitled to give or take under
the  relevant Indenture, the Depository would authorize the participants to give
such notice or  take such  action, and participants  would authorize  beneficial
owners  owning through such participants to give such notice or take such action
or would otherwise act upon the instructions of beneficial owners owning through
them.
 
                                       8
<PAGE>
    Unless otherwise specified in the applicable Prospectus Supplement, payments
with respect  to principal,  premium, if  any,  and interest,  if any,  on  Debt
Securities represented by a Registered Global Security registered in the name of
a  Depository or its nominee will be made  to such Depository or its nominee, as
the case may be, as the registered owner of such Registered Global Security.
 
    Protective  Life  expects  that  the  Depository  for  any  Debt  Securities
represented  by a  Registered Global  Security, upon  receipt of  any payment of
principal, premium or interest,  will immediately credit participants'  accounts
with  payments in amounts proportionate to their respective beneficial interests
in the  principal amount  of such  Registered Global  Security as  shown on  the
records  of  such  Depository. Protective  Life  also expects  that  payments by
participants to  owners  of  beneficial  interests  in  such  Registered  Global
Security   held  through  such   participants  will  be   governed  by  standing
instructions and customary  practices, as is  now the case  with the  securities
held for the accounts of customers registered in "street names", and will be the
responsibility   of  such   participants.  Nevertheless,   payments,  transfers,
exchanges and other  matters relating  to beneficial interests  in a  Registered
Global Security may be subject to various policies and procedures adopted by the
Depository  from time to time. None  of Protective Life, the respective Trustees
or any  agent of  Protective Life  or  the respective  Trustees shall  have  any
responsibility  or  liability  for any  aspect  of  the records  relating  to or
payments made  on  account  of  beneficial  interests  of  a  Registered  Global
Security,  or for maintaining, supervising or  reviewing any records relating to
such beneficial interests. (Section 3.8 of each Indenture.)
 
    Unless otherwise specified in the  applicable Prospectus Supplement, if  the
Depository  for any Debt Securities represented  by a Registered Global Security
notifies Protective  Life  that  it  is  unwilling  or  unable  to  continue  as
Depository and a successor Depository is not appointed by Protective Life within
90  days,  Protective  Life  will  issue  such  Debt  Securities  in  definitive
certificated form in exchange for such Registered Global Security. In  addition,
Protective Life may at any time and in its sole discretion determine not to have
any  of the Debt  Securities of a  series represented by  one or more Registered
Global Securities and, in such event, will issue Debt Securities of such  series
in  definitive certificated  form in exchange  for all of  the Registered Global
Security or Securities representing such  Debt Securities. (Section 3.5 of  each
Indenture.)
 
    The  Debt Securities of a series  may also be issued in  whole or in part in
the form of one  or more bearer global  securities (a "Bearer Global  Security")
that will be deposited with a depository, or with a nominee for such depository,
identified  in  the applicable  Prospectus  Supplement. Any  such  Bearer Global
Securities may be issued  in temporary or permanent  form. (Section 3.4 of  each
Indenture.)  The specific terms and procedures,  including the specific terms of
the depository arrangement,  with respect  to any portion  of a  series of  Debt
Securities  to be represented  by one or  more Bearer Global  Securities will be
described in the applicable Prospectus Supplement.
 
CONSOLIDATION, MERGER OR SALE BY PROTECTIVE LIFE
 
    Protective  Life  shall  not  consolidate  with  or  merge  into  any  other
corporation  or sell  its assets  substantially as  an entirety,  unless (i) the
corporation formed by such consolidation or into which Protective Life is merged
or the corporation which acquires its  assets is organized in the United  States
and  expressly  assumes all  of the  obligations of  Protective Life  under each
Indenture, (ii) immediately after giving effect to such transaction, no  Default
or  Event of Default  shall have happened and  be continuing and  (iii) if, as a
result of such transaction, properties or assets of Protective Life would become
subject to a mortgage, pledge, lien, security interest or other encumbrance  not
permitted by the Debt Securities of any series, Protective Life or its successor
shall  take steps necessary  to secure such Debt  Securities equally and ratably
with all indebtedness secured  thereby. Upon any  such consolidation, merger  or
sale,  the successor  corporation formed  by such  consolidation, or  into which
Protective Life is merged or to which  such sale is made, shall succeed to,  and
be  substituted for Protective  Life under each Indenture.  (Section 7.1 of each
Indenture.)
 
EVENTS OF DEFAULT, NOTICE AND CERTAIN RIGHTS ON DEFAULT
 
    Each Indenture  provides that,  if  an Event  of Default  specified  therein
occurs  with respect to the Debt Securities of any series and is continuing, the
Trustee   for   such   series   or    the   holders   of   25%   in    aggregate
 
                                       9
<PAGE>
principal  amount of all of  the outstanding Debt Securities  of that series, by
written notice to Protective Life (and to the Trustee for such series, if notice
is given by such holders of Debt Securities), may declare the principal of  (or,
if  the Debt Securities of that series are Original Issue Discount Securities or
Indexed Securities,  such  portion of  the  principal amount  specified  in  the
Prospectus  Supplement) and accrued interest on  all the Debt Securities of that
series to be  due and  payable (provided, with  respect to  any Debt  Securities
(including  Subordinated  Debentures) issued  under the  Subordinated Indenture,
that the payment of principal and interest on such Debt Securities shall  remain
subordinated   to  the  extent  provided  in  Article  12  of  the  Subordinated
Indenture). (Section 5.2 of each Indenture.)
 
    Except as otherwise provided in a Prospectus Supplement relating to the Debt
Securities of  a particular  series,  Events of  Default  with respect  to  Debt
Securities of any series are defined in each Indenture as being: (a) default for
30  days in payment of any  interest on any Debt Security  of that series or any
coupon appertaining thereto  or any  additional amount payable  with respect  to
Debt  Securities  of  such  series as  specified  in  the  applicable Prospectus
Supplement when due; (b) default in payment of principal, or premium, if any, at
maturity or on redemption or otherwise, or in the making of a mandatory  sinking
fund  payment of any Debt Securities of that series when due; (c) default for 60
days after notice to Protective Life by  the Trustee for such series, or by  the
holders  of 25%  in aggregate  principal amount of  the Debt  Securities of such
series then outstanding, in the performance  of any other agreement in the  Debt
Securities  of that series, in the Indenture or in any supplemental indenture or
board resolution referred  to therein under  which the Debt  Securities of  that
series  may have been  issued; (d) default  in payment of  principal relating to
indebtedness of Protective Life and  its consolidated subsidiaries for  borrowed
money  having an  aggregate principal  amount exceeding  $25 million  (after the
expiration of  any  applicable grace  period  with respect  thereto),  or  other
default  resulting in  acceleration of indebtedness  of Protective  Life and its
consolidated subsidiaries  for  borrowed  money where  the  aggregate  principal
amount so accelerated exceeds $25 million and such acceleration is not rescinded
or  annulled within 30 days after the  written notice thereof to Protective Life
by the Trustee or to  Protective Life and the Trustee  by the holders of 25%  in
aggregate   principal  amount  of  the  Debt  Securities  of  such  series  then
outstanding; PROVIDED that  such Event  of Default  will be  remedied, cured  or
waived  if the default that resulted in such Event of Default is remedied, cured
or waived; and (e) certain events of bankruptcy, insolvency or reorganization of
Protective Life or Protective Life  Insurance. (Section 5.1 of each  Indenture.)
Events  of Default with respect to a  specified series of Debt Securities may be
added to the Indenture  and, if so  added, will be  described in the  applicable
Prospectus Supplement. (Sections 3.1 and 5.1(7) of each Indenture.)
 
    Each  Indenture provides  that the  Trustee will,  within 90  days after the
occurrence of a Default with respect to the Debt Securities of any series,  give
to  the holders  of the Debt  Securities of  that series notice  of all Defaults
known to it unless such Default shall  have been cured or waived; PROVIDED  that
except  in the  case of  a Default  in payment  on the  Debt Securities  of that
series, the Trustee  may withhold  the notice  if and so  long as  the board  of
directors  of Protective Life, the executive committee thereof or a committee of
its Responsible Officers in good  faith determines that withholding such  notice
is  in  the interests  of the  holders of  the Debt  Securities of  that series.
(Section 6.6 of each  Indenture.) "Default" means any  event which is, or  after
notice  or passage of time or both, would  be, an Event of Default. (Section 1.1
of each Indenture.)
 
    Each Indenture  provides  that  the  holders  of  a  majority  in  aggregate
principal  amount of the Debt Securities of each series affected (with each such
series voting as a class) may, subject to certain limited conditions, direct the
time, method and place of conducting any proceeding for any remedy available  to
the  Trustee for such series, or exercising any trust or power conferred on such
Trustee. (Section 5.8 of each Indenture.)
 
    Each Indenture includes a covenant  that Protective Life will file  annually
with  the  Trustee a  certificate as  to Protective  Life's compliance  with all
conditions and covenants of such Indenture. (Section 9.6 of each Indenture.)
 
                                       10
<PAGE>
    The holders of  a majority in  aggregate principal amount  of any series  of
Debt  Securities by written notice to the  Trustee for such series may waive, on
behalf of the holders of all Debt Securities of such series, any past Default or
Event of  Default with  respect to  that series  and its  consequences except  a
Default or Event of Default in the payment of the principal of, premium, if any,
or interest, if any, on any Debt Security. (Section 5.7 of each Indenture.)
 
MODIFICATION OF THE INDENTURES
 
    Each  Indenture  contains  provisions  permitting  Protective  Life  and the
Trustee to enter into one or more supplemental indentures without the consent of
the holders  of  any  of the  Debt  Securities  in order  (i)  to  evidence  the
succession  of another corporation to Protective  Life and the assumption of the
covenants of Protective Life by a successor  to Protective Life; (ii) to add  to
the  covenants of Protective Life or surrender  any right or power of Protective
Life; (iii) to add additional  Events of Default with  respect to any series  of
Debt  Securities;  (iv)  to add  or  change  any provisions  to  such  extent as
necessary to permit  or facilitate  the issuance  of Debt  Securities in  bearer
form;  (v) to change  or eliminate any provision  affecting only Debt Securities
not yet issued; (vi) to secure the Debt Securities; (vii) to establish the  form
or  terms  of Debt  Securities;  (viii) to  evidence  and provide  for successor
Trustees or to  add or  change any  provisions to  such extent  as necessary  to
permit  or  facilitate the  appointment of  a separate  Trustee or  Trustees for
specific series  of  Debt Securities;  (ix)  if allowed  without  penalty  under
applicable laws and regulations, to permit payment in respect of Debt Securities
in bearer form in the United States; (x) to correct any defect or supplement any
inconsistent  provisions or to make any other provisions with respect to matters
or questions arising under  such Indenture or to  cure any ambiguity or  correct
any  mistake,  PROVIDED  that any  such  action  does not  adversely  affect the
interests of any holder  of Debt Securities of  any series then Outstanding;  or
(xi)  in the  case of  the Subordinated  Indenture, to  modify the subordination
provisions thereof  in a  manner  not adverse  to  the holders  of  Subordinated
Debentures  of  any series  then Outstanding  (and in  the case  of Subordinated
Debentures issued in  return for  the proceeds  of Preferred  Securities of  any
series   then  Outstanding,  not  adverse  to  the  holders  of  such  Preferred
Securities). (Section 8.1 of each Indenture.)
 
    Each Indenture also contains provisions  permitting Protective Life and  the
Trustee,  with the consent of  the holders of a  majority in aggregate principal
amount  of  the  outstanding  Debt  Securities  affected  by  such  supplemental
indenture  (with  the Debt  Securities of  each  series voting  as a  class), to
execute  supplemental  indentures  adding  any  provisions  to  or  changing  or
eliminating  any  of  the  provisions  of  such  Indenture  or  any supplemental
indenture or modifying  the rights  of the holders  of Debt  Securities of  such
series,  except that, without the consent of the holder of each Debt Security so
affected, no such supplemental indenture may: (i) change the time for payment of
principal or premium, if any, or interest on any Debt Security; (ii) reduce  the
principal  of,  or any  installment  of principal  of,  or premium,  if  any, or
interest on any Debt Security, or change  the manner in which the amount of  any
of  the foregoing is determined;  (iii) reduce the interest  rate, the amount of
principal or the amount of premium, if  any, payable upon the redemption of  any
Debt  Security; (iv) reduce the amount of principal payable upon acceleration of
the maturity of any Original Issue Discount or Indexed Security; (v) change  the
currency  or currency unit in which any Debt Security or any premium or interest
thereon is payable; (vi) impair the right to institute suit for the  enforcement
of  any  payment on  or  with respect  to any  Debt  Security; (vii)  reduce the
percentage in  principal  amount of  the  outstanding Debt  Securities  affected
thereby  the consent of whose holders  is required for modification or amendment
of such Indenture  or for waiver  of compliance with  certain provisions of  the
Indenture  or for  waiver of certain  defaults; (viii) change  the obligation of
Protective Life  to maintain  an office  or agency  in the  places and  for  the
purposes  specified  in such  Indenture; (ix)  in the  case of  the Subordinated
Indenture, modify the subordination  provisions thereof in  a manner adverse  to
the  holders of Subordinated  Debentures of any series  then Outstanding (and in
the case  of  Subordinated Debentures  issued  in  return for  the  proceeds  of
Preferred  Securities of any series then  Outstanding, adverse to the holders of
such Preferred Securities); or (x) modify  the provisions relating to waiver  of
certain  defaults  or any  of  the foregoing  provisions.  (Section 8.2  of each
Indenture.)
 
                                       11
<PAGE>
SUBORDINATION UNDER THE SUBORDINATED INDENTURE
 
    In the Subordinated  Indenture, Protective  Life has  covenanted and  agreed
that any Subordinated Debt Securities (including Subordinated Debentures) issued
thereunder  are  subordinate  and  junior  in right  of  payment  to  all Senior
Indebtedness  to  the  extent  provided  in  the  Subordinated  Indenture.   The
Subordinated  Indenture defines the term "Senior Indebtedness" as the principal,
premium, if  any, and  interest  on (i)  all  indebtedness of  Protective  Life,
whether  outstanding on the date of the issuance of Subordinated Debt Securities
or thereafter created,  incurred or  assumed, which  is for  money borrowed,  or
which  is evidenced by a note or similar instrument given in connection with the
acquisition of any  business, properties or  assets, including securities,  (ii)
any  indebtedness of others of  the kinds described in  the preceding clause (i)
for the payment of which Protective  Life is responsible or liable as  guarantor
or  otherwise and (iii)  amendments, renewals, extensions  and refundings of any
such indebtedness,  unless  in  any  instrument  or  instruments  evidencing  or
securing  such indebtedness or pursuant to which  the same is outstanding, or in
any such amendment, renewal,  extension or refunding,  it is expressly  provided
that  such indebtedness is not superior in right of payment to Subordinated Debt
Securities. The Senior Indebtedness shall continue to be Senior Indebtedness and
entitled to the  benefits of  the subordination provisions  irrespective of  any
amendment,  modification or  waiver of  any term  of the  Senior Indebtedness or
extension or renewal of the Senior Indebtedness.
 
    If (i) Protective Life defaults in the payment of any principal, or premium,
if any, or interest  on any Senior  Indebtedness when the  same becomes due  and
payable, whether at maturity or at a date fixed for prepayment or declaration or
otherwise  or  (ii)  an event  of  default  occurs with  respect  to  any Senior
Indebtedness permitting the holders thereof  to accelerate the maturity  thereof
and  written  notice  of such  event  of  default (requesting  that  payments on
Subordinated Debt Securities cease) is given  to Protective Life by the  holders
of  Senior Indebtedness, then unless and until  such default in payment or event
of default shall have  been cured or  waived or shall have  ceased to exist,  no
direct  or  indirect payment  (in cash,  property or  securities, by  set-off or
otherwise) shall be made  or agreed to  be made on  account of the  Subordinated
Debt  Securities or interest thereon or in respect of any repayment, redemption,
retirement, purchase or other acquisition of Subordinated Debt Securities.
 
    In the event of (i)  any insolvency, bankruptcy, receivership,  liquidation,
reorganization,  readjustment, composition or  other similar proceeding relating
to Protective Life, its creditors or  its property, (ii) any proceeding for  the
liquidation,  dissolution or other  winding-up of Protective  Life, voluntary or
involuntary, whether  or not  involving  insolvency or  bankruptcy  proceedings,
(iii) any assignment by Protective Life for the benefit of creditors or (iv) any
other  marshalling of  the assets  of Protective  Life, all  Senior Indebtedness
(including, without limitation, interest accruing after the commencement of  any
such  proceeding, assignment  or marshalling of  assets) shall first  be paid in
full before any payment  or distribution, whether in  cash, securities or  other
property,  shall  be made  by Protective  Life on  account of  Subordinated Debt
Securities. In any  such event, any  payment or distribution,  whether in  cash,
securities  or other property  (other than securities of  Protective Life or any
other corporation provided for  by a plan of  reorganization or a  readjustment,
the  payment of  which is subordinate,  at least  to the extent  provided in the
subordination provisions  of  the Subordinated  Indenture  with respect  to  the
indebtedness  evidenced by Subordinated  Debt Securities, to  the payment of all
Senior Indebtedness at  the time  outstanding and  to any  securities issued  in
respect  thereof under any  such plan of  reorganization or readjustment), which
would otherwise (but for the subordination provisions) be payable or deliverable
in respect  of  Subordinated Debt  Securities  (including any  such  payment  or
distribution which may be payable or deliverable by reason of the payment of any
other  indebtedness  of Protective  Life being  subordinated  to the  payment of
Subordinated Debt Securities) shall be paid or delivered directly to the holders
of Senior Indebtedness,  or to  their representative or  trustee, in  accordance
with   the  priorities  then  existing  among  such  holders  until  all  Senior
Indebtedness shall have been paid  in full. No present  or future holder of  any
Senior Indebtedness shall be prejudiced in the right to enforce subordination of
the indebtedness evidenced by Subordinated Debt Securities by any act or failure
to act on the part of Protective Life.
 
                                       12
<PAGE>
    Senior Indebtedness shall not be deemed to have been paid in full unless the
holders  thereof shall have received cash, securities or other property equal to
the amount of  such Senior Indebtedness  then outstanding. Upon  the payment  in
full  of all  Senior Indebtedness, the  holders of  Subordinated Debt Securities
shall be subrogated to all the rights  of any holders of Senior Indebtedness  to
receive   any  further  payments  or  distributions  applicable  to  the  Senior
Indebtedness until  all Subordinated  Debt Securities  shall have  been paid  in
full,  and such payments or distributions received by any holder of Subordinated
Debt Securities, by  reason of such  subrogation, of cash,  securities or  other
property  which otherwise would be paid or  distributed to the holders of Senior
Indebtedness, shall, as between Protective Life and its creditors other than the
holders of Senior Indebtedness, on the one hand, and the holders of Subordinated
Debt Securities, on the other, be deemed  to be a payment by Protective Life  on
account  of  Senior  Indebtedness,  and  not  on  account  of  Subordinated Debt
Securities.
 
    The  Subordinated  Indenture  provides  that  the  foregoing   subordination
provisions,  insofar as they relate to any particular issue of Subordinated Debt
Securities, may be  changed prior  to such issuance.  Any such  change would  be
described  in  the  Prospectus  Supplement relating  to  such  Subordinated Debt
Securities.
 
    The Subordinated Indenture places no limitation on the amount of  additional
Senior  Indebtedness that  may be incurred  by Protective  Life. Protective Life
expects from time to time  to incur additional indebtedness constituting  Senior
Indebtedness.
 
DEFEASANCE AND COVENANT DEFEASANCE
 
    If  indicated in the  applicable Prospectus Supplement,  Protective Life may
elect either (i) to defease and be discharged from any and all obligations  with
respect  to the  Debt Securities  of or within  any series  (except as otherwise
provided in the relevant Indenture) ("defeasance")  or (ii) to be released  from
its  obligations  with  respect  to certain  covenants  applicable  to  the Debt
Securities of or  within any  series ("covenant defeasance"),  upon the  deposit
with  the  relevant Trustee  (or other  qualifying trustee),  in trust  for such
purpose, of money  and/or Government  Obligations which through  the payment  of
principal  and interest in accordance with their  terms will provide money in an
amount sufficient, without reinvestment, to pay the principal of and any premium
or interest on such Debt Securities to  Maturity or redemption, as the case  may
be, and any mandatory sinking fund or analogous payments thereon. As a condition
to  defeasance  or  covenant defeasance,  Protective  Life must  deliver  to the
Trustee an Officer's Certificate  and an Opinion of  Counsel to the effect  that
the  Holders of such Debt Securities will not recognize income, gain or loss for
Federal income  tax  purposes  as  a  result  of  such  defeasance  or  covenant
defeasance  and will be subject to federal income tax on the same amounts and in
the same manner  and at  the same  times as  would have  been the  case if  such
defeasance  or covenant defeasance had not occurred. Such Opinion of Counsel, in
the case of defeasance under clause (i) above, must refer to and be based upon a
ruling of the Internal Revenue Service or a change in applicable federal  income
tax  law  occurring  after  the  date  of  the  relevant  Indenture.  Additional
conditions to defeasance include (x) delivery by Protective Life to the  Trustee
of  an Officer's Certificate to the effect that neither such Debt Securities nor
any other Debt Securities of the same  series, if then listed on any  securities
exchange,  will be  delisted as  a result  of such  defeasance, (y)  no Event of
Default with  respect to  such  Debt Securities  or  any other  Debt  Securities
occurring  or  continuing at  the time  of such  defeasance or,  in the  case of
certain bankruptcy Events of Default,  at any time on or  prior to the 90th  day
after  the date of such defeasance and  (z) such defeasance not resulting in the
trust arising  from the  deposit of  any moneys  in respect  of such  defeasance
constituting  an  "investment  company"  within the  meaning  of  the Investment
Company Act unless such trust shall be registered under such Act or exempt  from
registration  thereunder. (Article  4 of  each Indenture.)  If indicated  in the
applicable Prospectus  Supplement,  in addition  to  obligations of  the  United
States  or  an agency  or  instrumentality thereof,  Government  Obligations may
include obligations of  the government or  an agency or  instrumentality of  the
government  issuing the  currency or currency  unit in which  Debt Securities of
such series are payable. (Sections 1.1 and 3.1 of each Indenture.)
 
    In addition, with  respect to  the Subordinated  Indenture, in  order to  be
discharged  no  event  or  condition  shall  exist  that,  pursuant  to  certain
provisions described under "-- Subordination under the
 
                                       13
<PAGE>
Subordinated  Indenture"  above,  would  prevent  Protective  Life  from  making
payments of principal of (and premium, if any) and interest on Subordinated Debt
Securities  and  coupons appertaining  thereto at  the  date of  the irrevocable
deposit referred to above. (Section 4.6 of the Subordinated Indenture.)
 
    Protective Life may exercise its defeasance option with respect to such Debt
Securities notwithstanding its prior exercise of its covenant defeasance option.
If Protective  Life  exercises  its  defeasance option,  payment  of  such  Debt
Securities  may not be accelerated because of an Event of Default. If Protective
Life exercises its covenant defeasance  option, payment of such Debt  Securities
may  not be  accelerated by  reason of  a Default  or an  Event of  Default with
respect to  the  covenants to  which  such covenant  defeasance  is  applicable.
However,  if  such acceleration  were to  occur  by reason  of another  Event of
Default, the  realizable  value  at  the acceleration  date  of  the  money  and
Government  Obligations in the defeasance trust could be less than the principal
and interest then due on such Debt  Securities, in that the required deposit  in
the defeasance trust is based upon scheduled cash flow rather than market value,
which will vary depending upon interest rates and other factors.
 
NOTICES
 
    Notices  to holders of registered  Debt Securities will be  given by mail to
the addresses of such holders as they  may appear in the Register. (Section  1.6

owner thereof (whether or not such Debt Security may be overdue) for the purpose
of receiving payment and for all other purposes. (Section 3.8 of each Indenture)
 
GOVERNING LAW
 
    The Indentures and the Debt Securities will be governed by, and construed in
accordance  with,  the laws  of the  State of  New York.  (Section 1.11  of each

THE TRUSTEES
 
    The Bank of New York is the Trustee under the Senior Indenture. AmSouth Bank
is the  Trustee  under the  Subordinated  Indenture. Protective  Life  may  also
maintain  banking and other  commercial relationships with  each of the Trustees

certain limitations on the right of each Trustee, should it become a creditor of
Protective Life, to obtain payment of claims in certain cases, or to realize for
its  own account on  certain property received  in respect of  any such claim as
security or otherwise. Each Trustee will be permitted to engage in certain other
transactions; however, if it  acquires any conflicting interest  and there is  a
default under the Debt Securities, it must eliminate such conflict or resign.

<PAGE>
    In general, the classes of authorized capital stock are afforded preferences
with  respect to dividends and liquidation rights in the order listed above. The
Board of Directors  of Protective  Life is  empowered, without  approval of  the
stockholders,  to cause the Preferred Stock to  be issued in one or more series,
with the  numbers of  shares of  each  series and  the rights,  preferences  and
limitations of each series to be determined by it. The specific matters that may
be  determined by the Board of Directors include the dividend rights, conversion
rights, redemption rights  and liquidation  preferences, if any,  of any  wholly
unissued series of Preferred Stock (or of the entire class of Preferred Stock if
none  of such shares  have been issued),  the number of  shares constituting any
such series and the terms and conditions of the issue thereof. The  descriptions
set  forth  below do  not  purport to  be complete  and  are qualified  in their
entirety by  reference  to the  (i)  Restated Certificate  of  Incorporation  of
Protective  Life, as amended (the "Restated Certificate of Incorporation"), (ii)
the By-laws of Protective Life and (iii) the Rights Agreement, copies of each of
which are  filed  as  exhibits  to the  Registration  Statement  of  which  this
Prospectus forms a part.
 
    No  holders of any class of Protective  Life's capital stock are entitled to
preemptive rights.
 
               DESCRIPTION OF PREFERRED STOCK OF PROTECTIVE LIFE
 
    The particular  terms  of  any  series of  Preferred  Stock  offered  hereby
("Offered  Preferred  Stock") will  be set  forth  in the  Prospectus Supplement
relating  thereto.  The  rights,   preferences,  privileges  and   restrictions,
including  dividend rights, voting  rights, terms of  redemption and liquidation
preferences, of the  Offered Preferred  Stock of each  series will  be fixed  or
designated  pursuant to  a certificate  of designation  adopted by  the Board of
Directors or a duly authorized committee  thereof. The description of the  terms
of  a particular series of  Offered Preferred Stock that will  be set forth in a
Prospectus Supplement does not  purport to be complete  and is qualified in  its
entirety by reference to the certificate of designation relating to such series.
 
                 DESCRIPTION OF COMMON STOCK OF PROTECTIVE LIFE
 
GENERAL
 
    Subject  to the rights of the holders of any shares of 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
Protective  Life, 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 Protective
Life, the holders of Common Stock are entitled to receive, after payment of  all
of  Protective Life'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
Protective Life. Holders  of 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.  AmSouth Bank  of
Birmingham,  Alabama is the  registrar and transfer agent  for the Common Stock.
The Common Stock is listed on the New York Stock Exchange under the symbol "PL."
 
CERTAIN PROVISIONS
 
    The provisions of  Protective Life's Restated  Certificate of  Incorporation
that  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  to be  in such  stockholder's  best interests,  including those
attempts that might result  in a premium  over the market  price for the  shares
held by stockholders.
 
    ISSUANCE  OF  PREFERRED  STOCK.   Pursuant  to the  Restated  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  rights, dividend rates,  liquidation and other  rights,
 
                                       15
<PAGE>
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 Protective Life.
 
    BUSINESS  COMBINATIONS.     Protective   Life's  Restated   Certificate   of
Incorporation  contains a "fair  price" provision which  generally requires that
certain  "Business  Combinations"  with   a  "Related  Person"  (generally   the
beneficial  owner of at least  20 percent of Protective  Life's voting stock) be
approved by the holders of at least 80 percent of Protective Life's voting stock
and the holders of at least 67 percent of the voting stock held by  stockholders
other  than such Related  Person, unless (a)  the transaction is  approved by at
least a majority of  the "Continuing Directors" of  Protective Life, or (b)  the
Business  Combination is either a "Reorganization"  or a Business Combination in
which Protective Life  is the surviving  corporation and, in  either event,  the
cash  or fair market value of the property, securities or other consideration to
be received per share as a result of the Business Combination by holders of  the
Common  Stock of Protective Life other than  the Related Person is not less than
the highest per share price (with appropriate adjustments for  recapitalizations
and  for  stock splits,  stock dividends  and like  distributions) paid  by such
Related Person  in acquiring  any  holdings of  Protective Life's  Common  Stock
either  in or subsequent to the transaction  or series of transactions by reason
of which the Related Person became a Related Person. Protective Life's  Restated
Certificate   of  Incorporation  defines  "Business   Combination"  as  (i)  any
Reorganization of Protective Life or a  subsidiary of Protective Life, (ii)  any
sale,   lease,  exchange,  transfer  or  other  disposition,  including  without
limitation a  pledge, mortgage  or any  other  security device,  of all  or  any
"Substantial Part" of the assets either of Protective Life or of a subsidiary of
Protective  Life, (iii) any sale, lease, exchange, transfer or other disposition
of all or any "Substantial Part" of  the assets of an entity to Protective  Life
or  a subsidiary  of Protective  Life, (iv)  the issuance  of any  securities of
Protective Life or  any subsidiary of  Protective Life except  if such  issuance
were a stock split, stock dividend or other distribution pro rata to all holders
of  the same class of voting stock, (v) any recapitalization or reclassification
of Protective Life's securities (including  any reverse stock split) that  would
have  the  effect of  increasing  the voting  power of  an  entity and  (vi) any
agreement, contract,  plan  or  other  arrangement  providing  for  any  of  the
transactions  described in  the definition of  Business Transaction. "Continuing
Director" is  defined to  mean a  director  who was  a member  of the  Board  of
Directors  of Protective Life immediately prior  to the time such Related Person
became a Related Person. "Substantial Part"  is defined as more than 20  percent
of  the fair market value of the total assets of the corporation in question, as
determined in good faith by a majority of the Continuing Directors as of the end
of its most recent  fiscal year ending  prior to the  time the determination  is
being made. "Reorganization" is defined to mean a merger, consolidation, plan of
exchange, sale of all or substantially all of the assets (including, as pertains
to a subsidiary of Protective Life, bulk reinsurance or cession of substantially
all  of its  policies and contracts)  or other form  of corporate reorganization
pursuant to which  shares of voting  stock, or other  securities of the  subject
corporation,  are  to be  converted or  exchanged into  cash or  other property,
securities  or   other  consideration.   Under  the   Restated  Certificate   of
Incorporation,  the  amendment  of,  repeal  of  or  adoption  of  any provision
inconsistent with  provisions  of  the  Restated  Certificate  of  Incorporation
relating to Business Combinations with a Related Person requires the affirmative
vote of the holders of at least 80 percent of Protective Life's voting stock and
the  holders of at  least 67 percent  of Protective Life's  voting stock held by
holders other than such Related Person.
 
SHARE PURCHASE RIGHTS PLAN
 
    On July  13, 1987,  the Board  of Directors  of Protective  Life declared  a
dividend  distribution of one Right for  each outstanding share of Common Stock.
The distribution was payable on July 28,  1987 to the shareholders of record  on
that date. Each Right entitles the registered holder to purchase from Protective
Life  one one-hundredth of a  share of Junior Preferred Stock  at a price of $52
per one  one-hundredth of  a  share of  Junior  Preferred Stock  (the  "Purchase
Price"), subject to adjustment.
 
    Until  the earlier to occur  of (i) ten days following  the time of a public
announcement or notice to Protective Life  that a person or group of  affiliated
or associated persons (an "Acquiring Person") acquired, or obtained the right to
acquire,   beneficial   ownership   of   20%   or   more   of   the  outstanding
 
                                       16
<PAGE>
Common Stock of Protective Life (the "Stock Acquisition Time") or (ii) ten  days
following  the commencement  or announcement  of an  intention to  make a tender
offer or exchange offer which, if successful, would cause the bidder to own  30%
or  more of the outstanding Common Stock (the earlier of such dates being called
the "Distribution Date"), the Rights will  be evidenced, with respect to any  of
the  Common Stock certificates outstanding  as of July 28,  1987, by such Common
Stock certificate with  a copy of  a "Summary of  Rights" attached thereto.  The
Rights  Agreement provides that, until the Distribution Date, the Rights will be
transferred with and only with the Common Stock. Until the Distribution Date (or
earlier redemption or expiration of  the Rights), new Common Stock  certificates
issued  after July 28, 1987, upon transfer  or new issuance of the Common Stock,
will contain a notation incorporating  the Rights Agreement by reference.  Until
the  Distribution Date (or earlier redemption  or expiration of the Rights), the
surrender for transfer of any of the Common Stock certificates outstanding as of
July 28, 1987, even without  a copy of a  "Summary of Rights" attached  thereto,
will  also  constitute the  transfer of  the Rights  associated with  the Common
Shares represented by  such certificate.  As soon as  practicable following  the
Distribution   Date,  separate   certificates  evidencing   the  Rights  ("Right
Certificates") will be mailed to holders of record of the Common Stock as of the
close of business on the Distribution Date and such separate Right  Certificates
alone will evidence the Rights.
 
    The  Rights are not exercisable until the Distribution Date. The Rights will
expire on July 28, 1997, unless earlier redeemed by Protective Life as described
below or extended.
 
    The Purchase Price  payable, and  the number and  kind of  shares of  Junior
Preferred  Stock or other securities or  property issuable, upon exercise of the
Rights are subject to adjustment  from time to time  to prevent dilution (i)  in
the   event  of  a   stock  dividend  on,  or   a  subdivision,  combination  or
reclassification of, the Junior Preferred Stock, (ii) upon the grant to  holders
of  Junior Preferred Stock  of certain rights, options  or warrants to subscribe
for or purchase Junior  Preferred Stock or convertible  securities at less  than
the   current  market  price  of  Junior  Preferred  Stock  or  (iii)  upon  the
distribution to holders of Junior  Preferred Stock of evidences of  indebtedness
or  assets (excluding  regular periodic cash  dividends or  dividends payable in
Junior Preferred Stock) or of subscription rights or warrants (other than  those
referred  to  above).  The number  of  Rights  and number  of  shares  of Junior
Preferred Stock  issuable  upon  the  exercise of  each  Right  are  subject  to
adjustment  in the event of a stock  split, combination or stock dividend on the
Common Stock.
 
    In the  event that  after the  Stock Acquisition  Time, Protective  Life  is
acquired  in a merger or other business combination transaction or more than 50%
of its assets or earning power is  sold, proper provision shall be made so  that
each  holder of a Right (other than  the Acquiring Person) shall thereafter have
the right to  receive, upon the  exercise thereof at  the then-current  exercise
price  of the  Right, that  number of  shares of  common stock  of the acquiring
company which at the time of such  transaction would have a market value of  two
times  the exercise price of  the Right. In the  event that Protective Life were
the surviving corporation in a  merger and its Common  Stock was not changed  or
exchanged,  or in the event that an Acquiring  Person engages in one of a number
of self-dealing transactions specified in the Rights Agreement, proper provision
shall be made so that each holder  of a Right (other than the Acquiring  Person)
will thereafter have the right to receive upon exercise that number of shares of
the  Common Stock  (or, in certain  circumstances, a combination  of cash, other
property, Preferred Stock, Common Stock and/or other securities) having a market
value of two times the exercise price of the Right.
 
    With certain  exceptions,  no  adjustment  in the  Purchase  Price  will  be
required  until cumulative adjustments  require an adjustment of  at least 1% in
such Purchase Price. No fractions of Rights or fractional shares will be  issued
(other  than fractional shares which are integral multiples of one one-hundredth
of a share of Junior Preferred Stock which may, upon the election of  Protective
Life,  be evidenced by depository receipts)  and, in lieu thereof, an adjustment
in cash will be made based on the market price of the Rights or Junior Preferred
Stock, as the case may be, on the last trading date of exercise.
 
    At any  time prior  to the  earlier of  ten business  days following  public
announcement  or notice to Protective Life that  a person or group of affiliated
or associated persons has acquired beneficial
 
                                       17
<PAGE>
ownership of 20% or more of the outstanding shares of Common Stock and July  28,
1997,  Protective Life  may redeem the  Rights in whole,  but not in  part, at a
price of $.01 per Right (the  "Redemption Price"). After such redemption  period
has  expired,  Protective Life's  right of  redemption may  be reinstated  if an
Acquiring Person  reduces  his  beneficial  ownership  to  5%  or  less  of  the
outstanding  shares of Common Stock. 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 $.01 Redemption Price
per Right.
 
    Until a Right is exercised, the holder thereof, as such, will have no rights
as  a  stockholder of  Protective Life,  other than  rights resulting  from such
holder's ownership of shares of Common Stock, including, without limitation, the
right to vote or to receive dividends. While the distribution of the Rights will
not be  taxable  to  stockholders  or  to  Protective  Life,  stockholders  may,
depending upon the circumstances, recognize taxable income in the event that the
Rights   become  exercisable  for  Common  Stock  (or  other  consideration)  of
Protective Life or for common stock of the acquiring company as set forth above.
 
    The Rights and the Rights Agreement can be amended by the Board of Directors
of Protective Life (after the Stock Acquisition Time, only with the approval  of
a  majority of the Continuing Directors) in  any respect whatsoever up until the
close of business  on the  tenth business  day following  the Stock  Acquisition
Time,  and  thereafter in  certain respects  which do  not adversely  affect the
interests of holders of  Right Certificates (other than  an Acquiring Person  or
its affiliates of associates).
 
    For  purposes of the Rights Agreement,  the term "Continuing Director" means
any member of the Board of Directors of Protective Life who was a member of  the
Board  prior to the Stock  Acquisition Time, and any  person who is subsequently
elected to the Board if such person is recommended or approved by a majority  of
the  Continuing  Directors, but  shall not  include an  Acquiring Person,  or an
affiliate or associate  of an  Acquiring Person,  or any  representative of  the
foregoing entities.
 
    The  Rights  have  certain  anti-takeover  effects.  The  Rights  will cause
substantial dilution to a  person or group that  attempts to acquire  Protective
Life  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 Protective Life which  are not approved by Protective  Life's
Board  of Directors. However, the Rights should not interfere with any merger or
other business combination approved by Protective Life's Board of Directors.
 
    The foregoing  description  of the  Rights  Agreement is  qualified  in  its
entirety  by reference to the  complete terms of the Rights  as set forth in the
Rights Agreement.  The  Rights Agreement  is  incorporated by  reference  as  an
exhibit to the Registration Statement of which this Prospectus is a part. A copy
of   the  Rights  Agreement  can  be  obtained  as  described  under  "Available
Information".
 
DESCRIPTION OF JUNIOR PREFERRED STOCK
 
    GENERAL.  In connection with the Rights Agreement, 150,000 shares of  Junior
Preferred  Stock have been reserved and authorized  for issuance by the Board of
Directors  of  Protective  Life.  No  shares  of  Junior  Preferred  Stock   are
outstanding  as of  the date of  this Prospectus. The  following statements with
respect to the  Junior Preferred Stock  do not  purport to be  complete and  are
subject  to the detailed provisions of the Restated Certificate of Incorporation
and the certificate of designation relating  to the Junior 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 Preferred Stock  shall rank junior to all other  series
of  Protective Life'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 share of any  series of Preferred Stock ranking prior to  and
superior to the shares of Junior Preferred Stock with
 
                                       18
<PAGE>
respect  to  dividends, the  holders  of shares  of  Junior Preferred  Stock, in
preference to the holders of  Common Stock and of  any other junior stock  which
may  be outstanding, shall be  entitled to receive, when,  as and if declared by
the Board  of  Directors  out  of funds  legally  available  for  that  purpose,
quarterly dividends payable in cash on the first day of January, April, July and
October  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 Preferred
Stock, in an amount per share (rounded to the nearest cent) equal to the greater
of (a) $2.50 per  share ($10.00 per  annum) 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 Preferred Stock.
 
    Protective Life  shall declare  a  dividend or  distribution on  the  Junior
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 $2.50  per
share  ($10.00 per  annum) on the  Junior Preferred Stock  shall nevertheless be
payable on such subsequent Quarterly Dividend Payment Date.
 
    VOTING RIGHTS.  The holders of  shares of Junior Preferred Stock shall  have
the  following voting  rights: (a) subject  to adjustment  upon certain dilutive
events, each share of Junior Preferred Stock shall entitle the holder thereof to
100 votes (and each one one-hundredth of a share of Junior Preferred Stock shall
entitle the holder thereof to  one vote) on all matters  submitted to a vote  of
the  stockholders of  Protective Life; (b)  except as otherwise  provided by the
Certificate of Designation, the Restated Certificate of Incorporation, any other
certificate of designation creating a series  of preferred stock or any  similar
stock or by law, the holders of shares of Junior 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  Protective Life;  and (c)  except  as
provided  in the  Certificate of  Designation or  by applicable  law, holders of
Junior Preferred Stock  shall have no  special voting rights  and their  consent
shall not be required for authorizing or taking any corporate action.
 
    LIQUIDATION,  DISSOLUTION OR WINDING UP.  Upon any liquidation (voluntary or
otherwise), dissolution or winding up of Protective Life, 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 Preferred Stock
unless, prior thereto,  the holders of  shares of Junior  Preferred Stock  shall
have  received the higher of (i) $100 per share, plus an amount equal to accrued
and unpaid dividends and distributions thereon, whether or not declared, to  the
date  of  such  payment, or  (ii)  an  aggregate amount  per  share,  subject to
adjustment upon certain dilutive events, equal to 100 times the aggregate amount
to be  distributed  per  share  to  holders  of  Common  Stock;  nor  shall  any
distribution  be made to the holders of stock  ranking on a parity (either as to
dividends or  upon  liquidation,  dissolution or  winding-up)  with  the  Junior
Preferred Stock, except distributions made ratably on the Junior Preferred Stock
and  all other such parity stock in proportion to the total amounts to which the
holders of all such  shares are entitled upon  such liquidation, dissolution  or
winding-up.
 
    CONSOLIDATION,  MERGER, ETC.   In case Protective Life  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, or otherwise  changed, then in  any such case,  each
share of Junior Preferred Stock shall at the same time be similarly exchanged or
changed  into 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.
 
                                       19

    CERTAIN RESTRICTIONS.   Whenever quarterly dividends  or other dividends  or
distributions  payable on the Junior Preferred  Stock are in arrears, thereafter
and until all  accrued and unpaid  dividends and distributions,  whether or  not
declared,  on shares of Junior Preferred  Stock outstanding shall have been paid
in full, Protective Life shall not: (i) declare or pay dividends on, or make any
other distributions  on  any  shares  or stock  ranking  junior  (either  as  to
dividends  or  upon  liquidation,  dissolution  or  winding-up)  to  the  Junior
Preferred Stock; (ii) declare or pay dividends, or make any other distributions,
on any shares  of stock  ranking on  a parity (either  as to  dividends or  upon
liquidation,  dissolution or winding-up) with  the Junior Preferred Stock except
dividends paid ratably on the Junior Preferred Stock, and all such parity  stock
on  which the  dividends are payable  or in  arrears in proportion  to the total
amounts to which the holders of all such shares are then entitled; (iii)  redeem
or  purchase or otherwise acquire for  consideration shares of any stock ranking
on a  parity  (either  as  to dividends  or  upon  liquidation,  dissolution  or
winding-up)  with the Junior Preferred Stock,  provided that Protective Life may
at any time  redeem, purchase  or otherwise acquire  shares of  any such  parity
stock  in exchange  for shares  of any stock  of Protective  Life ranking junior
(either as to dividends or upon  liquidation, dissolution or winding-up) to  the
Junior  Preferred Stock; or (iv) purchase or otherwise acquire for consideration
any shares of Junior Preferred Stock, or any shares of stock ranking on a parity
(either as to dividends or upon liquidation, dissolution or winding-up) with the
Junior Preferred  Stock, except  in accordance  with a  purchase offer  made  in
writing  or by  publication (as  determined by  the Board  of Directors)  to all
holders of  such  shares  upon such  terms  as  the Board  of  Directors,  after
consideration  of the respective annual dividend rates and other relative rights
and preferences of  the respective series  or classes, shall  determine in  good
faith will result in fair and equitable treatment among the respective series or
classes.  Protective Life shall not permit  any subsidiary of Protective Life to
purchase  or  otherwise  acquire  for  consideration  any  shares  of  stock  of
Protective  Life unless Protective Life could,  in accordance with the foregoing
restrictions, purchase or otherwise acquire such shares at such time and in such
manner.
 
    REDEMPTION.  The shares of Junior Preferred Stock are not redeemable.
 
CERTAIN LIMITATIONS ON DIVIDENDS AND OTHER PAYMENTS
 
    Under the terms of  the 9% Subordinated Debentures,  Series A of  Protective
Life (the "Series A Subordinated Debentures"), so long as Protective Life is not
in  default in the payment of interest  on the Series A Subordinated Debentures,
Protective Life has the right at any time to extend the interest payment  period
to  the next interest payment date by a period (not to exceed 60 months from the
last date on which interest was paid in full). During any such extended interest
period, or at  any time during  which there is  an uncured Default  or Event  of
Default  (as defined  in the  Subordinated Indenture,  see "Description  of Debt
Securities of Protective Life -- Events of Default, Notice and Certain Rights on
Default") under  the  Series  A  Subordinated  Debentures,  Protective  Life  is
prohibited  from paying any dividends on, or redeeming, purchasing, acquiring or
making a liquidation payment with respect to, any of its shares of capital stock
or make any  guarantee payments with  respect to the  foregoing (other than  (a)
redemptions  or purchases pursuant to the Rights Agreement or any successor plan
to the share purchase plan established pursuant to such Rights Agreement and (b)
payments under  any guarantee  of the  Series A  Preferred Securities  or  other
Preferred Securities ranking PARI PASSU with the Series A Preferred Securities).
 
               DESCRIPTION OF PREFERRED SECURITIES OF PLC CAPITAL
 
    The issued capital of PLC Capital consists of one Class A Interest, which is
owned by Protective Life, one Class B Interest, which is owned by a wholly-owned
subsidiary  of Protective Life, and $55,000,000 in aggregate principal amount of
Series A Preferred Securities  which are listed on  the New York Stock  Exchange
under the trading symbol "PL Pr M."
 
    PLC Capital is authorized to issue from time to time Preferred Securities in
one  or  more  series,  with  such  dividend  rights,  liquidation  preferences,
redemption provisions,  voting rights  and other  rights, powers  and duties  as
shall be established by the L.L.C. Agreement and written actions (the "Actions")
taken,  or to be taken, by the  Managing Member establishing such rights, powers
and duties (which
 
                                       20
<PAGE>
Actions, when taken,  constitute an amendment  and supplement to,  and become  a
part  of,  the L.L.C.  Agreement). The  L.L.C.  Agreement has  been filed  as an
exhibit to the Registration Statement of which this Prospectus forms a part, and
a copy of  the Action relating  to Preferred  Securities of any  series will  be
filed  with the Commission at or prior to  the time of the sale of the Preferred
Securities of such  series. Preferred  Securities will be  issued in  registered
form only.
 
    The  Managing Member is authorized, subject  to the provisions of the L.L.C.
Agreement, to establish by Actions for each series of Preferred Securities,  and
the  applicable  Prospectus  Supplement shall  set  forth with  respect  to such
series: (i) the maximum number of Preferred Securities to constitute such series
and the distinctive designation thereof; (ii) the dividend rate, the  conditions
and dates upon which such dividends shall be payable, the preference or relation
which  such dividends shall bear to the  dividends payable on any other class of
Membership Securities  or  on any  other  series of  Preferred  Securities,  and
whether  such dividends shall be cumulative  or noncumulative; (iii) whether the
Preferred Securities of such series shall be subject to redemption, and, if  so,
the times, prices and other terms and conditions thereof; (iv) the rights of the
holders of Preferred Securities of such series upon the dissolution, liquidation
or  winding-up  of PLC  Capital; (v)  whether the  Preferred Securities  of such
series shall be subject to a retirement or sinking fund, and, if so, the extent,
terms and  provisions  relative  to  the operation  thereof;  (vi)  whether  the
Preferred  Securities of any  series shall be  convertible into, or exchangeable
for, Membership Securities  of any other  class or series  or securities of  any
other  kind,  including  securities issued  by  Protective  Life or  any  of its
affiliates, and, if  so, the price  or rate  of conversion or  exchange and  any
method of adjusting the same; (vii) the limitations and restrictions, if any, to
be applicable while any Preferred Securities of such series are outstanding upon
the  payment of  dividends or  making of  other distributions  on, and  upon the
purchase, redemption or other acquisition  by PLC Capital of, Common  Securities
or  any other class  of Membership Securities  or any other  series of Preferred
Securities ranking junior to the Preferred  Securities of such series either  as
to dividends or upon liquidation; (viii) the conditions or restrictions, if any,
upon  the  creation of  indebtedness of  PLC Capital  or upon  the issue  of any
additional Membership Securities (including  additional Preferred Securities  of
such  series or of  any other series) ranking  on a parity with  or prior to the
Preferred Securities of such series as  to dividends or distributions of  assets
upon  liquidation; (ix)  the voting rights,  if any, of  Preferred Securities of
such series; and (x) any other relative  rights, powers and duties as shall  not
be  inconsistent with the L.L.C. Agreement. In connection with the foregoing the
Managing Member is  authorized to take  any action, including  amendment of  the
L.L.C.  Agreement,  without the  vote  or approval  of  any holder  of Preferred
Securities (other than the requisite vote or approval, if any, of holders of any
outstanding series of Preferred Securities to the extent provided in the  Action
relating to such series), including any Action to create under the provisions of
the  L.L.C. Agreement  a class  (or series  of a  class) or  group of Membership
Securities that was not previously outstanding.
 
    All Preferred Securities  of any  one series  shall be  identical with  each
other in all respects, except that Preferred Securities of any one series issued
at  different times  may differ as  to the  dates from which  dividends, if any,
thereon shall  be cumulative.  All  series of  Preferred Securities  shall  rank
equally  and be  identical in  all respects, except  as permitted  by the L.L.C.
Agreement provisions summarized  in the preceding  paragraph, and all  Preferred
Securities  shall rank senior to the Common  Securities both as to dividends and
upon liquidation. The  Common Securities  are also  subject to  all the  rights,
powers  and duties of the Preferred Securities  as are established in the L.L.C.
Agreement and as  shall be  established in any  Actions of  the Managing  Member
pursuant to the authority summarized in the preceding paragraph.
 
   DESCRIPTION OF CERTAIN CONTRACTUAL BACK-UP OBLIGATIONS OF PROTECTIVE LIFE
 
THE GUARANTEE OF CERTAIN PAYMENTS
 
    Protective  Life, by an irrevocable and unconditional subordinated guarantee
(the "Guarantee"), will agree, to the limited extent set forth herein and in the
related Prospectus  Supplement, to  pay in  full, to  the holders  of  Preferred
Securities of any series, the Guarantee Payments (as defined below), as and when
due,  regardless  of any  defense, right  of set-off  or counterclaim  which PLC
Capital may have or assert.
 
                                       21
<PAGE>
The Guarantee will  constitute a  guarantee of payment  and may  be enforced  by
holders  of Preferred Securities directly against Protective Life. The following
payments to the extent not made  by PLC Capital (the "Guarantee Payments")  will
be  subject  to the  Guarantee (without  duplication):  (i) any  accumulated and
unpaid  dividends  which  have  theretofore  been  declared  on  the   Preferred
Securities of such series out of funds held by PLC Capital and legally available
therefor;  (ii)  the  redemption  price (including  all  accumulated  and unpaid
dividends whether or not declared) payable, out of funds held by PLC Capital and
legally available therefor,  with respect  to any Preferred  Securities of  such
series  called for  redemption by  PLC Capital;  and (iii)  in the  event of any
dissolution, liquidation or  winding-up of PLC  Capital, the lesser  of (a)  the
aggregate  of the  liquidation preference  of the  Preferred Securities  of such
series and all accumulated and unpaid dividends (whether or not declared) to the
date of payment and (b)  the amount of remaining  assets of PLC Capital  legally
available  to  holders  of Preferred  Securities  of such  series.  In addition,
Protective Life will unconditionally and irrevocably guarantee, in the event  of
any  exchange by PLC Capital of Preferred Securities for Subordinated Debentures
(to the extent permitted by the Action for such Preferred Securities),  delivery
of  certificates representing the proper  amount of such Subordinated Debentures
in conformity with the Action for  such series. Protective Life's obligation  to
make  a Guarantee  Payment may  be satisfied by  direct payment  of the required
amounts by Protective Life to the holders of Preferred Securities of such series
or by causing PLC Capital  to pay such amounts  to such holders. The  Prospectus
Supplement  relating  to  a series  of  Preferred Securities  will  describe any
additional covenants  or other  terms  of the  Guarantee  with respect  to  such
series.  The Guarantee  will rank PARI  PASSU with  Subordinated Debentures and,
accordingly, will be subordinate  and junior in right  of payment to all  Senior
Indebtedness  in a manner identical to that described under "Description of Debt
Securities  of  Protective   Life  --  Subordination   under  the   Subordinated
Indenture."
 
    THE  GUARANTEE IS NOT A GUARANTEE THAT  ANY PARTICULAR DIVIDEND OR AMOUNT ON
LIQUIDATION, DISSOLUTION OR WINDING  UP WILL BE PAID;  RATHER, THE GUARANTEE  IS
SOLELY  A GUARANTEE OF PAYMENT  OF DIVIDENDS, IF ANY,  THAT ARE IN FACT DECLARED
OUT OF  FUNDS  HELD  BY PLC  CAPITAL  AND  LEGALLY AVAILABLE  THEREFOR,  OF  THE
REDEMPTION PRICE PAYABLE, OUT OF FUNDS HELD BY PLC CAPITAL AND LEGALLY AVAILABLE
THEREFOR,  WITH RESPECT  TO THE  PREFERRED SECURITIES  OF ANY  SERIES CALLED FOR
REDEMPTION BY PLC CAPITAL AND OF AMOUNTS, IF ANY, AVAILABLE FOR DISTRIBUTION  TO
THE  HOLDERS  OF  THE  PREFERRED  SECURITIES  OF  ANY  SERIES  UPON LIQUIDATION,
DISSOLUTION OR WINDING UP AFTER SATISFACTION OF ALL CREDITORS OF PLC CAPITAL.
 
SUBORDINATED DEBENTURES
 
    Protective Life  will  issue  Subordinated  Debentures  to  PLC  Capital  to
evidence  the loans to be  made by PLC Capital of  the proceeds of (i) Preferred
Securities of  each  series  and  (ii) Common  Securities  and  related  capital
contributions   ("Common  Securities   Payments").  See   "Description  of  Debt
Securities of Protective Life" for a  summary of the material provisions of  the
Subordinated  Indenture, under which the Subordinated Debentures will be issued.
References to provisions of the Subordinated Indenture in this Prospectus and in
the relevant Prospectus Supplement are qualified in their entirety by  reference
to  the text of the Subordinated Indenture, a form of which has been filed as an
exhibit to the Registration Statement of which this Prospectus forms a part. The
aggregate dollar amount  of the  Subordinated Debentures  relating to  Preferred
Securities of any series will be set forth in the Prospectus Supplement for such
series  and will  equal the  aggregate liquidation  preference of  the Preferred
Securities of such series, together with the related Common Securities Payments.
 
                              PLAN OF DISTRIBUTION
 
    Protective Life may  sell any of  the Debt Securities,  Preferred Stock  and
Common  Stock, and PLC Capital  may sell any of  the Preferred Securities, being
offered hereby in any one or more of  the following ways from time to time:  (i)
through agents; (ii) to or through underwriters; (iii) through dealers; and (iv)
directly by Protective Life or PLC Capital, as the case may be, to purchasers.
 
    The distribution of the Offered Securities may be effected from time to time
in one or more transactions at a fixed price or prices, which may be changed, at
market  prices  prevailing  at the  time  of  sale, at  prices  related  to such
prevailing market prices or at negotiated prices.
 
                                       22
<PAGE>
    Offers to purchase Offered Securities may be solicited by agents  designated
by  Protective Life or PLC Capital,  as the case may be,  from time to time. Any
such agent involved in the offer or sale of the Offered Securities in respect of
which this Prospectus is delivered will be named, and any commissions payable by
Protective Life  or  PLC  Capital to  such  agent  will be  set  forth,  in  the
applicable  Prospectus Supplement. Unless otherwise indicated in such Prospectus
Supplement, any such agent will be acting on a reasonable best efforts basis for
the period  of  its  appointment.  Any  such  agent  may  be  deemed  to  be  an
underwriter,  as that  term is  defined in  the Securities  Act, of  the Offered
Securities so offered and sold.
 
    If Offered  Securities  are  sold  by means  of  an  underwritten  offering,
Protective  Life and/or PLC Capital will  execute an underwriting agreement with
an underwriter  or  underwriters at  the  time an  agreement  for such  sale  is
reached,  and the names of the specific managing underwriter or underwriters, as
well as any  other underwriters,  and the  terms of  the transaction,  including
commissions,  discounts  and  any  other compensation  of  the  underwriters and
dealers, if any, will be  set forth in the  Prospectus Supplement which will  be
used by the underwriters to make resales of the Offered Securities in respect of
which  this Prospectus is delivered to  the public. If underwriters are utilized
in the sale of  the Offered Securities  in respect of  which this Prospectus  is
delivered, the Offered Securities will be acquired by the underwriters for their
own  account and may  be resold from time  to time in  one or more transactions,
including negotiated transactions, at fixed public offering prices or at varying
prices determined by the underwriter at the time of sale. Offered Securities may
be offered to the public  either through underwriting syndicates represented  by
managing   underwriters  or  directly  by  the  managing  underwriters.  If  any
underwriter or underwriters are utilized in the sale of the Offered  Securities,
unless  otherwise  indicated  in  the  Prospectus  Supplement,  the underwriting
agreement will provide that the obligations  of the underwriters are subject  to
certain conditions precedent and that the underwriters with respect to a sale of
Offered  Securities will be obligated to purchase all such Offered Securities if
any are purchased.
 
    If a dealer is utilized in the sale of the Offered Securities in respect  of
which  this Prospectus is delivered, Protective Life or PLC Capital, as the case
may be, will sell such Offered Securities to the dealer as principal. The dealer
may then resell such Offered  Securities to the public  at varying prices to  be
determined  by such dealer at the time of  resale. Any such dealer may be deemed
to be an  underwriter, as such  term is defined  in the Securities  Act, of  the
Offered  Securities so offered and sold. The name of the dealer and the terms of
the transaction will be set forth in the Prospectus Supplement relating thereto.
 
    Offers  to  purchase  Offered  Securities  may  be  solicited  directly   by
Protective  Life or PLC Capital, as the case may be, and the sale thereof may be
made by  Protective  Life or  PLC  Capital, as  the  case may  be,  directly  to
institutional  investors or others, who may  be deemed to be underwriters within
the meaning of the Securities Act with respect to any resale thereof. The  terms
of  any  such sales  will  be described  in  the Prospectus  Supplement relating
thereto.
 
    Agents, underwriters and dealers may  be entitled under relevant  agreements
with  Protective Life and/or  PLC Capital to  indemnification by Protective Life
and/or PLC Capital against certain liabilities, including liabilities under  the
Securities  Act, or to contribution with  respect to payments which such agents,
underwriters and dealers may be required to make in respect thereof.
 
    Each series of Offered  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. Any Common Stock sold  pursuant to a Prospectus Supplement  will
be  listed on such exchange, subject  to official notice of issuance. Protective
Life may elect to list any series of Debt Securities or Preferred Stock, and PLC
Capital may elect to  list any series of  Preferred Securities, on an  exchange,
but neither company shall be obligated to do so. It is possible that one or more
underwriters  may make a market in a  series of Offered 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 Offered Securities.
 
    Agents, underwriters and dealers may be customers of, engage in transactions
with, or perform services for,  Protective Life and its subsidiaries  (including
PLC Capital) in the ordinary course of business.
 
                                       23
<PAGE>
    Offered  Securities may  also be  offered and sold,  if so  indicated in the
Prospectus Supplement, in connection with a remarketing upon their purchase,  in
accordance with a redemption or repayment pursuant to their terms, or otherwise,
by  one or more firms ("remarketing firms"),  acting as principals for their own
accounts or as agents for  Protective Life or PLC Capital,  as the case may  be.
Any  remarketing firm will be identified and the terms of its agreement, if any,
with Protective Life or  PLC Capital and its  compensation will be described  in
the  Prospectus Supplement. Remarketing firms may  be deemed to be underwriters,
as such term is defined  in the Securities Act,  in connection with the  Offered
Securities   remarketed  thereby.  Remarketing  firms   may  be  entitled  under
agreements which may be entered into with Protective Life to indemnification  or
contribution  by  Protective  Life  and/or  PLC  Capital  against  certain civil
liabilities,  including  liabilities  under  the  Securities  Act,  and  may  be
customers  of, engage  in transactions with  or perform  services for Protective
Life and its  subsidiaries (including  PLC Capital)  in the  ordinary course  of
business.
 
    If  so indicated in the applicable Prospectus Supplement, Protective Life or
PLC Capital, as the case may  be, may authorize agents, underwriters or  dealers
to  solicit offers by  certain institutions to  purchase Offered Securities from
Protective Life or  PLC Capital,  as the  case may  be, at  the public  offering
prices  set forth  in the applicable  Prospectus Supplement  pursuant to delayed
delivery contracts  ("Contracts")  providing  for  payment  and  delivery  on  a
specified  date or  dates. A commission  indicated in  the applicable Prospectus
Supplement will be paid to underwriters, dealers and agents soliciting purchases
of Offered Securities pursuant to Contracts accepted by Protective Life.
 
                             VALIDITY OF SECURITIES
 
    Unless otherwise  indicated in  the  applicable Prospectus  Supplement,  the
validity  of any Offered Securities offered hereby  and of the Guarantee and the
Subordinated Debentures  relating to  any Preferred  Securities of  PLC  Capital
offered  hereby  will be  passed upon  for  Protective Life  and PLC  Capital by
Debevoise &  Plimpton,  875  Third  Avenue,  New York,  New  York  and  for  any
underwriters  or agents by Sullivan & Cromwell,  125 Broad Street, New York, New
York. Debevoise  & Plimpton  and Sullivan  & Cromwell  may rely  upon  Richards,
Layton  &  Finger, P.A.,  special Delaware  counsel to  Protective Life  and PLC
Capital, as to all matters of Delaware law relating to any Preferred Securities.

    The consolidated balance sheets of Protective  Life as of December 31,  1993
and 1992 and the related consolidated statements of income, stockholder's equity
and cash flows for each of the three years in the period ended December 31, 1993
and  the  related  financial  statement  schedules  which  are  incorporated  by
reference or included in  Protective Life's Annual Report  on Form 10-K for  the
year  ended December 31, 1993  and which have been  incorporated by reference in
this Prospectus, have been incorporated herein in reliance on the report,  which
includes  an explanatory paragraph with respect  to changes in Protective Life's
methods of accounting for certain investments  in debt and equity securities  in
1993  and  postretirement benefits  other than  pensions in  1992, of  Coopers &
Lybrand L.L.P., independent accountants, given on the authority of that firm  as
experts in accounting and auditing.
 
    With  respect to the unaudited  interim financial information for Protective
Life Corporation and subsidiaries  for the three-month  periods ended March  31,
1994  and 1993 and the three-month and six-month periods ended June 30, 1994 and
1993 incorporated by reference in  this Prospectus, the independent  accountants
have  reported  that they  have applied  limited  procedures in  accordance with
professional standards for a review of such information. However, their separate
report included in the Registration Statement  of which this Prospectus forms  a
part  states that they did not audit and  they do not express an opinion on such
interim financial  information. Accordingly,  the degree  of reliance  on  their
report  on such information should be restricted  in light of the limited nature
of the  review  procedures applied.  The  accountants  are not  subject  to  the
liability  provisions of  Section 11  of the  Securities Act  of 1933  for their
report on the unaudited interim financial information because that report is not
a "report" or a  "part" of the Registration  Statement prepared or certified  by
the accountants within the meaning of Sections 7 and 11 of the Act.
