    Protective  Life Corporation ("Protective Life"  or the "Company") may offer
from time to  time up  to $45,000,000 aggregate  initial offering  price of  its
Medium-Term  Notes (the  "Notes"). Each  Note will mature  on a  Business Day 15
years or more  from the  date of  issue, as  specified in  a pricing  supplement
hereto  (each a "Pricing Supplement"), and is  subject to redemption in whole or
in part prior to its Stated Maturity (as defined herein) under the circumstances
and subject to  the limitations  described under  "Description of  the Notes  --
Limited  Right of Redemption  At Option of Beneficial  Owner." In addition, each
Note may be subject to redemption by Protective Life, in whole or in part, prior
to its Stated  Maturity, as set  forth therein and  specified in the  applicable
Pricing Supplement.
 
    The  interest rate applicable to  each Note and other  variable terms of the
Notes as described herein will be established by Protective Life at or prior  to
the  date of issue of such Note and will be set forth therein and specified in a
Pricing Supplement. Interest rates and such other variable terms are subject  to
change  by Protective Life, but  no change will affect  any Note already issued.
The Notes may be  issued with original issue  discount. See "Description of  the

"Depository"). Beneficial interests in  the global Notes will  be shown on,  and
transfers  thereof  will be  effected only  through,  records maintained  by the
Depository, its nominee and its participants. Except as described herein,  Notes
in definitive form will not be issued.
 
    The  Notes will be senior unsecured obligations of the Company and will rank
PARI PASSU in right of payment with  all existing and future senior debt of  the
Company.  The  Notes will  be effectively  subordinated to  any debt  secured by
assets of the  Company to the  extent of the  value of such  assets, unless  the
Notes are also secured by such assets. See "Description of the Notes."

                          PROTECTIVE LIFE CORPORATION
 
    Protective  Life, 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.  Unless  the context
otherwise requires,  as used  in this  Prospectus Supplement  "Protective  Life"
refers  to  the  consolidated group  of  Protective Life  and  its subsidiaries.
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  nine  months  ended
September  30, 1996, Protective  Life reported revenues of  $772 million and net
income of $64.4 million. At September 30, 1996, Protective Life had total assets
of $8.0 billion,  stockholders' equity  of $572  million and  life insurance  in
force  of  $67.5  billion.  Protective  Life  Insurance  Company,  the Company's
principal operating subsidiary, was founded in  1907 and is currently rated  "A+
(Superior)"  by A.M. Best Company, Inc. ("A.M. Best"). A.M. Best, an independent
insurance industry  rating  organization,  assigns  fifteen  letter  ratings  to
insurance  companies, ranging from "A++ (Superior)"  to "C- (Fair)." A.M. Best's
ratings are based on factors of relevance primarily to policyholders and are not
directed to the  protection of  investors, such as  holders of  the Notes.  Such
ratings do not apply to the Notes offered hereby.
    
 
    Protective  Life is  organized around  six primary  divisions: Acquisitions,
Financial Institutions, Group, Guaranteed Investment Contracts, Individual  Life
and  Investment Products. The Company has  an additional business segment, which
is referred to in this Prospectus Supplement as Corporate and Other.
 
ACQUISITIONS DIVISION
 
    The Acquisitions  Division  focuses  solely  on  acquiring,  converting  and
servicing  blocks  of  insurance  policies acquired  from  other  companies. The
Company has long been an active acquirer of blocks of insurance policies and has
closed approximately 35 acquisitions over the last 25 years. These  acquisitions
are  generally  accomplished through  acquisitions of  companies or  through the
assumption or reinsurance  of policies or  coinsurance arrangements under  which
contractual  benefits and risks, and policy  reserves, associated with the block
are transferred  to  Protective Life  in  return for  the  payment of  a  ceding
commission  by Protective Life. Generally, such  acquisitions do not include the
acquisition of an active  sales force. Blocks of  policies acquired through  the
Acquisitions  Division are generally  administered as "closed"  blocks -- no new
policies are sold. Therefore, the amount of insurance in force for a  particular
block  of acquired business is  expected to decline with  time due to lapses and
deaths of the insureds.
 
FINANCIAL INSTITUTIONS DIVISION
 
    The 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. The Financial Institutions Division  also
offers  certain  products  through  direct  mail  solicitation  to  customers of
financial institutions. The Division has entered into a reinsurance  arrangement
whereby  all  of  the Division's  new  credit  insurance sales  are  ceded  to a
reinsurer.
 
GROUP DIVISION
 
    The Group  Division manufactures,  distributes and  services group,  dental,
cancer  and payroll  deduction insurance  products. Protective  Life markets its
group insurance products primarily in  the southeastern and southwestern  United
States    using   the   services   of    brokers   who   specialize   in   group
 
                                      S-3
<PAGE>
products. The Group Division offers  substantially all forms of group  insurance
customary  in  the  industry, making  available  complete packages  of  life and
accident and health insurance coverages, typically  to employee groups of 25  to
100.  The life and  accident and health insurance  packages include hospital and
medical coverages, as well as dental and disability coverages. To address rising
health care costs, the Group Division provides cost containment services such as
utilization review and catastrophic case management.
 
   
    The Group Division's  recent marketing  emphasis has been  on indemnity  and
managed-care  dental products.  The Group Division  was a  pioneer in developing
dental indemnity products  for the  voluntary payroll deduction  market. In  the
first  quarter of 1995,  Protective Life entered the  dental managed care market
when it acquired a  dental managed care company  which transacts business  under
the  trade name "DentiCare." The Group  Division provides a "dual choice" option
by offering DentiCare's products through the Company's existing indemnity dental
distribution channels.  At September  30, 1996,  the Company  had  approximately
373,000 members in its dental HMOs and over 848,000 individuals covered in total
by  its  dental programs.  The Group  Division  from time  to time  may consider
expanding the  dental business  through acquisitions.  In the  first quarter  of
1996,  the Group  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.
    
 
GUARANTEED INVESTMENT CONTRACTS DIVISION
 
    In 1989,  Protective  Life  began selling  guaranteed  investment  contracts
("GICs").  Protective Life's GICs are contracts, generally issued to a 401(k) or
other qualified  retirement savings  plan,  which guarantee  a fixed  return  on
deposits  with such a plan for a  specified period and often provide flexibility
for withdrawals, in keeping with the  benefits provided by the plan.  Protective
Life also offers related products, including fixed-rate contracts offered to the
trustees  of  municipal bond  proceeds, floating-rate  contracts issued  to bank
trust departments and  long-term annuity  contracts used to  fund certain  state
obligations.
 
INDIVIDUAL LIFE DIVISION
 
    The  Individual  Life Division  markets universal  and other  life insurance
products on a  national basis.  The Division primarily  utilizes a  distribution
system  based on experienced  independent personal producing  general agents who
are  recruited  by  regional  sales  managers.  The  Division  also  distributes
insurance  products through  stockbrokers, through the  payroll deduction market
and in the life  insurance brokerage market. The  Individual Life Division  also
offers  its products to other insurance companies and their distribution systems
under private label arrangements.
 
    Current marketing  efforts  in the  Individual  Life Division  are  directed
toward  the Company's various  universal life products  and products designed to
compete in the term market. Protective Life currently emphasizes back-end loaded
universal life  policies  which reward  the  continuing policyholder  and  which
should  help  maintain  the  persistency of  its  universal  life  business. The
products designed to  compete in the  term market place  are term-like  policies
with  guaranteed level premiums for the first ten, fifteen or twenty years which
provide a competitive net cost to the insured.
 
    The  Division  also  includes  ProEquities,  Inc.  ("PES"),  an   affiliated
securities  broker-dealer. Through PES, members of Protective Life's field force
who are licensed  to sell securities  can sell stocks,  bonds, mutual funds  and
investment  products that may be manufactured  or issued by companies other than
Protective Life.
 
INVESTMENT PRODUCTS DIVISION
 
    The  Investment  Products  Division  markets  fixed  and  variable   annuity
products,  which  are primarily  used  by consumers  as  a source  of retirement
savings.  The  Division's  annuity  products  are  sold  through  broker-dealers
(including PES), financial institutions and the Individual Life Division's agent
sales  force. The Investment  Products Division's primary  product is a variable
annuity that offers mutual funds managed by Goldman Sachs & Co.
 
                                      S-4
<PAGE>
CORPORATE AND OTHER
 
   
    The Corporate and Other segment consists of earnings from Protective  Life's
50%-owned  joint venture  with the Lippo  Group for the  marketing of individual
life insurance  in Hong  Kong,  unallocated net  investment income  on  capital,
interest  expense  on  substantially  all  debt,  charitable  contributions  and
earnings from several small insurance  lines of business and small  noninsurance
subsidiaries,  such  as Protective  Life's minority  interest in  QuickQuote, an
Internet-based insurance distribution system.
    
 
INVESTMENT PORTFOLIO
 
   
    The   Company   targets   three   primary   investment   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 September 30, 1996:

    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.  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 $231 million at September 30, 1996.
    
 
   
    In its approach to commercial mortgage loans, the Company has, for 25 years,
specialized in originating small (average new  loan size of $2.9 million)  loans
to  finance shopping centers, typically in  smaller communities. 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 September 30, 1996, 1.9%
of the commercial loan portfolio was classified as 90 days past due,  foreclosed
or  restructured, which the Company believes to be well below the life insurance
industry average.
    
 
                           INVESTMENT CONSIDERATIONS
 
    Set forth  below is  a discussion  of certain  considerations which  may  be
relevant  to an investment  in the Notes.  For additional information concerning
these considerations  and  other  factors  which may  be  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 Annual Report on Form 10-K for the year ended December 31,
1995.
 
                                      S-5
<PAGE>
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  polices. 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. 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 reduce the tax-deferred status of life insurance and  annuity
products,  or to  increase the tax-deferred  status of  competing products, 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'  sale 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
 
                                      S-6
<PAGE>
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.
 
HOLDING COMPANY STRUCTURE
 
    Protective  Life is a holding company  that derives substantially all of its
operating  income  and  cash  flow  from  its  insurance  company  subsidiaries.
Protective  Life's  ability  to  pay its  obligations,  including  principal and
interest on  the Notes,  is affected  by the  ability of  its insurance  company
subsidiaries  to declare and distribute dividends  and to make other payments to
the Company. For a  description of certain restrictions  on the ability of  such
subsidiaries  to make  such payments  to Protective  Life, see  "Protective Life
Corporation" in the accompanying Prospectus.
 
                              RECENT DEVELOPMENTS
 
   
REFUND TO CERTAIN POLICYHOLDERS
    
 
   
    On October 7, 1996, Protective Life  announced that it would make  voluntary
refunds  to  certain  of its  cancer  insurance policyholders  and  would reduce
premium rates charged to such policyholders. Cancer sales brochures  distributed
by  the Company to its sales force nationwide from 1989 through 1991 stated that
premium rates could be  raised only after approval  by the policyholder's  state
insurance  department. That  statement was correct  in most states  in which the
brochures were used; however, in twelve states in which the brochures were used,
rate increases were filed with the  state insurance departments but no  approval
was  required for  the rate increases  to become effective.  Protective Life has
notified affected policyholders and will make  refunds and will roll back  rates
where  appropriate. The Company recorded a one-time charge of approximately $6.8
million pre-tax, $4.4 million after tax, or $.15 per share, in the quarter ended
September 30, 1996, representing the cost of the refunds and related expenses.

                                USE OF PROCEEDS
 
   
    The  net proceeds from the sale of the Notes, estimated to equal $43,255,000
(assuming payment  to the  Agent of  a 3.5%  commission on  the total  principal
amount  of the Notes), initially will  be used to repay outstanding indebtedness
of the  Company under  the  Credit Agreement,  dated as  of  July 30,  1993,  as
subsequently  amended, with certain commercial  lending institutions and AmSouth
Bank of Alabama,  as agent  for the lenders  (the "Revolver").  The Company  can
borrow  up to  $70 million on  an unsecured  basis under the  Revolver, which is
scheduled to terminate on July 31, 1998, unless terminated earlier in accordance
with its terms. As of September 30, 1996, a total of $44,000,000 was outstanding
under the Revolver. Each loan under the Revolver has a three-year maturity, with
a variable  interest rate  tied to  the London  Interbank Offering  Rate plus  a
specified  factor. As of September 30,  1996, the weighted average interest rate
on outstanding loans under  the Revolver was 5.8%.  While the net proceeds  from
the  sale of the Notes initially will  be used to repay outstanding indebtedness
under the Revolver, amounts may be reborrowed under the Revolver thereafter  and
used  for general  corporate purposes,  including the  Company's working capital
needs, possible  acquisitions  of additional  blocks  of insurance  policies  or
otherwise to support the continued growth of the Company's 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.
 
(2) Reduced by one-time adjustment of income  tax expense of $1,261 or $.05  per
    share due to increase in the corporate income tax rate from 34% to 35%.
 
(3)   Reflects  the  adoption  of  SFAS  No.  106,  "Employers'  Accounting  for
    Postretirement Benefits  Other Than  Pensions," which  decreased net  income
    $1,053 or $.04 per share.
 
(4)  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  and Investment Products
    business  segments  of  $2,600,  $3,000  and  $2,000,  respectively,   while
    decreasing income of the Corporate and Other segment.
 
   
(5)  Includes a $6,750 pre-tax,  $4,388 after tax, or  $0.15 per share, one-time
    charge to earnings related to the refund of cancer premiums.
    
 
   
(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  $3,713 in  both the  nine month  periods ended
    September 30, 1996 and 1995. Such  minority interest in 1996, 1995 and  1994
    arises  from payments made on Monthly  Income Preferred Securities issued in
    1994.
    
 
   
(7) 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.

(9) These data are for Protective Life's insurance subsidiaries and are 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 expense is  computed
    on  taxable earnings and (d) furniture and equipment, agents' debit balances
    and prepaid  expenses  are  charged directly  against  surplus  rather  than
    reported as assets.
    
 
   
(10)  The  ratio of  consolidated  earnings to  fixed  charges is  calculated by
    dividing the sum  of income  before income tax  (excluding pre-tax  minority
    interest  but not excluding dividends on Monthly Income Preferred Securities
    reported as minority  interest) and  interest expense on  debt, by  interest
    expense on debt.
    
 
   
(11)  The ratio of consolidated earnings to combined fixed charges and dividends
    on Monthly Income Preferred Securities is calculated by dividing the sum  of
    income  before  income  tax  (excluding pre-tax  minority  interest  but not
    excluding dividends  on  Monthly  Income Preferred  Securities  reported  as
    minority interest) and interest expense on debt, by interest expense on debt
    and dividends on Monthly Income Preferred Securities.
    
 
   
(12)  The  ratio of  consolidated  earnings to  interest  on debt,  dividends on
    Monthly Income  Preferred Securities  and  interest credited  on  investment
    products  is  calculated by  dividing the  sum of  income before  income tax
    (excluding pre-tax minority interest but not excluding dividends on  Monthly
    Income Preferred Securities reported as minority interest), interest expense
    on debt and interest credited on investment products, by the sum of interest
    expense  on  debt,  dividends  on Monthly  Income  Preferred  Securities and
    interest  credited  on  investment  products.  Investment  products  include
    products such as GICs and annuities.

                            DESCRIPTION OF THE NOTES
 
GENERAL
 
    The  Notes offered hereby will be issued  under a Senior Indenture, dated as
of June 1, 1994 (the  "Senior Indenture"), between the  Company and The Bank  of
New  York,  as  Trustee,  as supplemented  from  time  to time  by  one  or more
supplemental indentures (each a "Supplemental Indenture"), to be entered into by
the Company and the Trustee in respect of the Notes (the Senior Indenture, as so
amended and supplemented, is  referred to hereinafter  as the "Indenture").  The
form  of the  Senior Indenture has  been filed,  and a copy  of the Supplemental
Indentures referred to  above will  be filed,  as exhibits  to the  Registration
Statement  of which this  Prospectus Supplement and  the accompanying Prospectus
are a part. The following summary of certain provisions of the Indenture and  of
the  Notes (referred to in the accompanying Prospectus as the "Debt Securities")
supplements, and to the extent  inconsistent therewith replaces, the summary  of
certain  provisions  of  the  Debt  Securities  set  forth  in  the accompanying
Prospectus, to which reference is hereby made. These summaries together  address
the  material terms of the  Notes and the Indenture but  are subject to, and are
qualified in their  entirety by  reference to,  the text  of the  Notes and  the
Indenture,  including the  definitions therein  of certain  terms capitalized in
this Prospectus Supplement. The  following description of  the Notes will  apply
unless otherwise specified in an applicable Pricing Supplement.
 
   
    The  Notes are currently  limited to $45,000,000  aggregate initial offering
price. As of  the date  of this Prospectus  Supplement, the  Company has  issued
Notes  in  the aggregate  principal amount  of  $20 million.  The Notes  will be
offered on a continuing basis. Each Note  will have a maturity date of not  less
than  15 years from  the date of  issue ("Stated Maturity"),  as specified in an
applicable Pricing Supplement.
    
 
    Unless otherwise specified  in a  Pricing Supplement, each  Note shall  bear
interest  from the date of  issue at the fixed  rate per annum specified therein
and in the applicable Pricing Supplement. The Notes may be issued at significant
discounts from their principal amount payable at the Stated Maturity (or on  any
prior  date on  which the  principal or  a portion  of the  principal of  a Note
becomes due and payable,  whether by the declaration  of acceleration, call  for
redemption  at the option of the Company,  repayment at the option of the Holder
or otherwise)  (each such  date, a  "Maturity"),  and some  Notes may  not  bear
interest.
 
    Interest  rates and other variable terms of  the Notes are subject to change
by the  Company from  time to  time, but  no such  change will  affect any  Note
already  issued or  as to which  an offer to  purchase has been  accepted by the
Company. Interest rates  offered by the  Company with respect  to the Notes  may
differ  depending upon, among other things,  market conditions and the aggregate
principal amount of the Notes purchased in any single transaction.
 
    The Notes will be issued only  in fully registered form in denominations  of
$1,000  and  any integral  multiple thereof.  The Notes  will be  denominated in
United States dollars  and payments of  principal of, and  premium, if any,  and
interest on, the Notes will be made in United States dollars.
 
    The  provisions of Article 4 of  the Indenture relating to defeasance, which
are described in the accompanying Prospectus, will apply to the Notes.
 
    Reference is made to the accompanying  Prospectus for a detailed summary  of
additional provisions of the Notes and of the Indenture.
 
RANKING
 
   
    The Notes will be unsecured general obligations of the Company and will rank
PARI  PASSU  with all  other unsecured  and  unsubordinated indebtedness  of the
Company from  time  to  time  outstanding. The  Indenture  does  not  limit  the
aggregate  principal amount of  Debt Securities which  may be issued thereunder,
and Debt Securities may be  issued thereunder from time to  time in one or  more
series  up to the aggregate principal amount from time to time authorized by the
Company for each series.  Prior to the date  of this Prospectus Supplement,  the
Company had issued $95 million aggregate principal
    
 
                                      S-11
<PAGE>
   
amount  of Debt Securities, including $20  million aggregate principal amount of
the Notes, under the Indenture. The Company may, from time to time, without  the
consent  of the Holders of the Notes, provide for the issuance of Notes or other
Debt Securities under the Indenture in addition to the Notes offered hereby  and
the other Debt Securities previously issued.
    
 
    The  Notes  will be  senior  to future  unsecured  subordinated indebtedness
issued by the  Company, if any.  The Indenture does  not preclude the  Company's
Subsidiaries  from issuing  secured or  unsecured indebtedness.  Further, if the
Company issues secured indebtedness, to the extent the security granted consists
of capital stock in Restricted Subsidiaries, the Indenture requires the Notes to
be PARI PASSU as  to security, except in  the case of liens  (as defined in  the
Supplemental  Indenture relating to  a particular issuance of  Notes) (i) on the
shares of  stock of  a  subsidiary of  a  Person that  is  merged with  or  into
Protective  Life or a  Subsidiary securing debt  of such Person,  which debt was
outstanding prior to  such merger, but  only if  such pledge and  debt were  not
incurred  in  anticipation of  such  merger, (ii)  in  favor of  Protective Life
securing debt of  a Restricted  Subsidiary owed  to Protective  Life, (iii)  for
taxes  or  assessments  or  governmental  charges or  levies  not  then  due and
delinquent or the validity of which are  being contested, or (iv) created by  or
resulting from any litigation or legal proceeding being contested. To the extent
the  security  consists  of  assets  other  than  capital  stock  in  Restricted
Subsidiaries, the Indenture provides no corresponding protection for the  Notes.
Therefore,  indebtedness issued  by the Company's  Subsidiaries and indebtedness
issued by the Company secured by  assets other than capital stock of  Restricted
Subsidiaries  may be paid ahead  of the Notes in the  event of insolvency of the
Company or its Subsidiaries.
 
    The term "Restricted  Subsidiary" means  any Subsidiary  of Protective  Life
with  assets greater than or  equal to 20% of all  assets of Protective Life and
its  Subsidiaries,  computed  and  consolidated  in  accordance  with  generally
accepted accounting principles.
 
GLOBAL NOTES
 
    The  Notes will be issued in the form of one or more fully registered global
securities, representing  the  aggregate  principal amount  of  the  Notes  (the
"Global  Notes"), that will be deposited with,  or on behalf of, the Depository,
and registered in the name  of Cede & Co., the  nominee of the Depository,  and,
except  under circumstances  described in  the Prospectus  under "Description of
Debt Securities of Protective Life -- Global Debt Securities," Global Notes will
not be exchangeable for definitive Notes  and will not otherwise be issuable  as
definitive Notes.
 
    The  Depository has advised Protective Life that the Depository is a limited
purpose trust  company organized  under the  New York  Banking Law,  a  "banking
organization"  within the meaning of  the New York Banking  Law, a member of the
Federal Reserve System, a "clearing corporation"  within the meaning of the  New
York Uniform Commercial Code, and a "clearing agency" registered pursuant to the
provisions  of section 17A of  the Securities Exchange Act  of 1934, as amended.
The Depository holds securities  that its participants ("Participants")  deposit
with  it. The Depository  also facilitates the  settlement among Participants of
securities transactions, such as transfers and pledges, in deposited  securities
through  electronic computerized  book-entry changes  in Participants' accounts,
thereby eliminating the need for  physical movement of securities  certificates.
Participants  include securities  brokers and  dealers, banks,  trust companies,
clearing corporations and certain  other organizations ("Direct  Participants").
The  Depository is owned by  a number of its Direct  Participants and by the New
York Stock Exchange, Inc., the American  Stock Exchange, Inc., and the  National
Association  of Securities Dealers,  Inc. Access to  the Depository's book-entry
system is also  available to  others, such  as securities  brokers and  dealers,
banks   and  trust  companies  that  clear   through  or  maintain  a  custodial
relationship with a Direct Participant, either directly or indirectly ("Indirect
Participants"). The Rules applicable to the Depository and its participants  are
on file with the Securities and Exchange Commission.
 
    Principal and interest payments on the Notes will be made to the Depository.
The  Depository's practice  is to  credit Direct  Participants' accounts  on the
relevant payable date in accordance with their respective holdings shown on  the
Depository's   records   unless   the   Depository   has   reason   to   believe
 
                                      S-12
<PAGE>
that it will not receive payment on such payable date. Payments by  Participants
to  actual purchasers  of each Note  or their  transferees ("Beneficial Owners")
will be governed  by standing instructions  and customary practices,  as is  the
case  with  securities held  for the  accounts  of customers  in bearer  form or
registered in "street name," and will be the responsibility of such  Participant
and  not of  the Depository,  the Trustee,  or Protective  Life, subject  to any
statutory or regulatory  requirements as  may be in  effect from  time to  time.
Payment  of principal  and interest to  the Depository is  the responsibility of
Protective Life; disbursement of such  payments to Direct Participants shall  be
the  responsibility  of  the Depository;  and  disbursement of  payments  to the
Beneficial  Owners  shall   be  the  responsibility   of  Direct  and   Indirect
Participants.
 
    A  further description of the Depository's procedures with respect to Global
Notes is set forth  in the Prospectus under  "Description of Debt Securities  of
Protective Life -- Global Debt Securities."
 
    The  Depository has confirmed to the Company and the Trustee that it intends
to follow such procedures.
 
INTEREST
 
    Unless otherwise specified  in an applicable  Pricing Supplement, each  Note
will  bear interest from, and  including, the date of  issue, or the most recent
date to which interest has  been paid or duly  provided for, to, but  excluding,
the  next succeeding Interest Payment  Date or Maturity, as  the case may be, at
the rate per  annum stated  therein and  in the  applicable Pricing  Supplement,
until the principal amount thereof is paid or made available for payment. Unless
otherwise  specified in an applicable Pricing  Supplement, interest on the Notes
will be computed on the basis of a 360-day year of twelve 30-day months and, for
any period that is shorter than a full calendar month, will be calculated on the
basis of the actual number of days elapsed in such period.
 
    Unless otherwise specified  in an applicable  Pricing Supplement, the  Notes
will  bear interest at fixed rates. Interest on the Notes will accrue from their
date of  issue  and,  unless  otherwise  specified  in  the  applicable  Pricing
Supplement,  will  be payable  semi-annually  in arrears  on  such dates  as are
specified in the applicable Pricing Supplement and at a Maturity. Notes may also
be issued with original issue discount, and such Notes may or may not  currently
pay interest.
 
    The  interest  so payable  on  any Note  which  is punctually  paid  or duly
provided for on any Interest  Payment Date will be paid  to the Person in  whose
name such Note is registered at the close of business on the Regular Record Date
preceding  such Interest Payment Date. The interest so payable on any Note which
is not punctually paid or  duly provided for on  any Interest Payment Date  will
forthwith  cease  to  be  payable to  the  Person  in whose  name  such  Note is
registered on the relevant Regular Record Date, and such defaulted interest will
instead be payable to the  Person in whose name such  Note is registered on  the
Special  Record Date or  other specified date determined  in accordance with the
Indenture.
 
    Unless otherwise specified  in an applicable  Pricing Supplement, the  first
payment  of interest on any Note originally issued between a Regular Record Date
and the  related Interest  Payment Date  will be  on the  Interest Payment  Date
immediately  following the next succeeding Regular  Record Date. If any Interest
Payment Date or Maturity of a  Note falls on a day  that is not a Business  Day,
the  related payment of principal, premium, if  any, or interest will be made on
the next succeeding Business Day  as if made on the  date such payment was  due,
and  no interest will  accrue on the amount  so payable for  the period from and
after  such  Interest   Payment  Date  or   Maturity,  as  the   case  may   be.
Notwithstanding  the immediately preceding sentence, in  the event that any date
on which interest  is payable  on a  Note is  not a  Business Day  and the  next
succeeding  Business Day is in the next calendar year, such payment will be made
on the immediately preceding Business Day, with the same force and effect as  if
made on such date.
 
ORIGINAL ISSUE DISCOUNT NOTES
 
    Notes may be issued at a price less than their redemption price at Maturity,
resulting in such Notes being treated as if they were issued with original issue
discount for Federal income tax purposes
 
                                      S-13
<PAGE>
("Original  Issue  Discount  Notes").  Such Original  Issue  Discount  Notes may
currently pay no interest or interest at a rate which at the time of issuance is
below market  rates.  See "Certain  United  States Income  Tax  Considerations."
Certain  additional considerations relating to any Original Issue Discount Notes
may be described in the Pricing Supplement relating thereto.
 
LIMITED RIGHT OF REDEMPTION AT OPTION OF BENEFICIAL OWNER
 
    Unless the Notes have become due and payable prior to their Stated  Maturity
by  reason of an Event of  Default (or by reason of  redemption at the option of
the Company, if applicable), commencing on  the second anniversary of the  issue
date  of  the Notes  in  question the  Representative  (as defined  below)  of a
deceased Beneficial Owner of an interest in  the Notes has the right to  request
redemption  of all  or part  of his or  her interest  in the  Notes, in integral
multiples of $1,000, for payment prior to Stated Maturity, and the Company  will
redeem  the  same  subject to  the  limitations  that the  Company  will  not be
obligated to  redeem during  any twelve-month  period beginning  on such  second
anniversary or beginning on any subsequent anniversary thereof, (i) on behalf of
any  given deceased Beneficial Owner any interest  in the Notes which exceeds an
aggregate principal  amount of  $25,000 or  (ii) interests  in the  Notes in  an
aggregate  principal  amount exceeding  two percent  of the  aggregate principal
amount of  Notes originally  issued  under the  same Supplemental  Indenture  as
described  in the applicable Pricing Supplement. In the case of interests in the
Notes owned by  a deceased  Beneficial Owner, a  request for  redemption may  be
presented  to  the Trustee  at  any time  and in  any  principal amount.  If the
Company, although  not obligated  to do  so, chooses  to redeem  interests of  a
deceased  Beneficial Owner  in the  Notes in  any such  period in  excess of the
$25,000 limitation, such redemption, to the  extent that it exceeds the  $25,000
limitation for any Beneficial Owner, shall not be included in the computation of
the two-percent limitation for such period or any succeeding period.
 
    Subject  to the  $25,000 and the  two-percent limitations,  the Company will
upon the death  of any Beneficial  Owner redeem the  interest of the  Beneficial
Owner  in the Notes within 60 days following receipt by the Trustee of a validly
completed Redemption  Request  (as  defined  below),  including  all  supporting
documentation,   from  such  Beneficial   Owner's  personal  representative,  or
surviving joint tenant(s), tenant(s) by the entirety or tenant(s) in common,  or
other   persons  entitled   to  effect  such   a  Redemption   Request  (each  a
"Representative"). If a Redemption  Request on behalf  of a deceased  Beneficial
Owner  exceeds  the $25,000-per-prepayment-period  limitation, or  if Redemption
Requests  in   the   aggregate  exceed   the   two-percent-per-prepayment-period
limitation,  then such excess Redemption Request(s)  (subject in the case of the
$25,000 limitation  to the  provisions of  the last  sentence of  the  preceding
paragraph)  will be applied  to successive periods  in the order  of receipt for
prepayment, regardless  of  the  number  of  periods  required  to  redeem  such
interest, unless sooner withdrawn as described below.
 
    A  request  for  redemption of  an  interest in  the  Notes may  be  made by
delivering a request to the Participant  through whom the Beneficial Owner  owns
such  interest, in form satisfactory to  the Participant, together with evidence
of  death  of  the  Beneficial   Owner  and  authority  of  the   Representative
satisfactory  to the Participant and the Trustee. A Representative of a deceased
Beneficial Owner may make the request for redemption and shall submit such other
evidence of the  right to such  redemption as the  Participant or Trustee  shall
require.  The request  shall specify  the principal  amount of  the Notes  to be
redeemed. A request for redemption in  form satisfactory to the Participant  and
accompanied  by  the  documents  relevant to  the  request  as  described above,
together with a certification by the  Participant that it holds the interest  on
behalf  of the deceased  Beneficial Owner with  respect to whom  the request for
redemption is being made  (the "Redemption Request"), shall  be provided to  the
Depository  by a Participant and the Depository  will forward the request to the
Trustee. Redemption Requests, including  all supporting documentation, shall  be
in  form satisfactory  to the  Trustee and  no request  for redemption  shall be
considered  validly  made  until  the  Redemption  Request  and  all  supporting
documentation,  in form satisfactory to the Trustee, shall have been received by
the Trustee.
 
    The price to  be paid  by the Company  for an  interest in the  Notes to  be
redeemed  pursuant to  a Redemption Request  from a  deceased Beneficial Owner's
Representative is one hundred percent
 
                                      S-14
<PAGE>
(100%) of the principal amount thereof  plus accrued but unpaid interest on  the
principal  amount  redeemed to  the date  of  payment to  the Depository  of the
redemption price of such interest in the Notes. Subject to arrangements with the
Depository, payment of the redemption price  for an interest in the Notes  which
is  to be  redeemed shall  be made  to the  Depository within  60 days following
receipt by  the Trustee  of  the Redemption  Request, including  all  supporting
documentation,  and the Notes  to be redeemed in  the aggregate principal amount
specified in the Redemption Request submitted  to the Trustee by the  Depository
which  is to  be fulfilled  in connection with  such payment.  An acquisition of
Notes by the Company or its Subsidiaries other than by redemption at the  option
of  any Representative of a  deceased Beneficial Owner shall  not be included in
the computation of either the $25,000 or two-percent limitations for any period.
 
    Interests in the  Notes held by  tenants by the  entirety, joint tenants  or
tenants in common will be deemed to be held by a single Beneficial Owner and the
death  of a  tenant in common,  tenant by the  entirety or joint  tenant will be
deemed the death of a Beneficial Owner.  The death of a person who, during  such
person's  lifetime,  was  entitled  to  substantially all  of  the  rights  of a
Beneficial Owner will be deemed the death of the Beneficial Owner, regardless of
the recordation of  such interest  on the records  of the  Participant, if  such
rights  can  be  established to  the  satisfaction  of the  Participant  and the
Trustee. Such interests  shall be deemed  to exist in  typical cases of  nominee
ownership,  ownership  under the  Uniform  Gifts to  Minors  Act or  the Uniform
Transfers  to  Minors   Act,  community  property   or  other  joint   ownership
arrangements  between  a  husband  and  wife  (including  individual  retirement
accounts or Keogh plans maintained  solely by or for the  decedent or by or  for
the decedent and any spouse), and trust and certain other arrangements where one
person  has substantially all  of the rights  of a Beneficial  Owner during such
person's lifetime.
 
    Any Redemption Request may be withdrawn  upon delivery of a written  request
for  such withdrawal given to the Trustee  by the Depository prior to payment to
the Depository of the redemption price of the interest in the Notes.
 
    Because of the limitations on  the Company's obligation to redeem  interests
in the Notes as described above, no Beneficial Owner can have any assurance that
his interest in the Notes will be paid prior to Stated Maturity.
 
REDEMPTION AT THE OPTION OF THE COMPANY
 
    Unless  otherwise indicated in  a Pricing Supplement, the  Notes will not be
subject to any sinking fund. The Notes  will be redeemable at the option of  the
Company  prior to the  Stated Maturity only  if so specified  therein and in the
applicable Pricing  Supplement. If  so  specified, then  on  such dates  as  are
specified  in such Pricing Supplement a Note may be redeemed in whole or in part
in increments  of  $1,000  at  the  option of  the  Company  at  the  applicable
Redemption  Price specified in  such Pricing Supplement,  together with interest
thereon payable to the date of redemption, on notice given not more than 60  nor
less  than 30 days  prior to the date  of redemption and  in accordance with the
provisions of the Indenture.
 
    The Company may at  any time purchase  Notes at any price  or prices in  the
open  market or  otherwise. Notes  so purchased  by the  Company may  be held or
resold or, at  the discretion  of the Company,  surrendered to  the Trustee  for
cancellation.
 
CERTAIN RESTRICTIVE PROVISIONS
 
    The Indenture contains, among others, the following covenants:
 
    LIMITATIONS ON SALES OF CAPITAL STOCK OF RESTRICTED SUBSIDIARIES. Protective
Life is restricted from disposing of in any way any shares of capital stock of a
Restricted  Subsidiary (other than directors'  qualifying shares or dispositions
to a Subsidiary), and Restricted  Subsidiaries are restricted from disposing  of
in any way any shares of capital stock of any other Restricted Subsidiary (other
than for directors' qualifying shares or dispositions to Protective Life or to a
Subsidiary), except for the
 
                                      S-15
<PAGE>
disposition  of the  entire capital  stock of  such Restricted  Subsidiary owned
directly or indirectly  by Protective  Life for  a consideration  which, in  the
opinion of its Board of Directors, is at least equal to the fair value thereof.
 
    The  Company is  not required  pursuant to  the Indenture  to repurchase the
Notes, in whole or  in part, with  the proceeds of any  sale, transfer or  other
disposition  of any shares of capital stock  of any Restricted Subsidiary (or of
any  Subsidiary  having  any  direct  or  indirect  control  of  any  Restricted
Subsidiary). Further, the Indenture does not provide for any restrictions on the
Company's use of such proceeds.
 
    The Indenture does not contain any provisions that will restrict the Company
from  incurring, assuming or becoming liable with respect to any indebtedness or
other obligations, whether  secured or  unsecured, or from  paying dividends  or
making  other distributions on its capital  stock or purchasing or redeeming its
capital stock. The Indenture does not contain any financial ratios or  specified
levels  of net worth or liquidity to which the Company must adhere. In addition,
the Indenture does not contain any provision that would require that the Company
repurchase or redeem or otherwise  modify the terms of any  of the Notes upon  a
change  in control  or other  events involving  the Company  which may adversely
affect the creditworthiness of the Notes.
 
    LIMITATIONS ON LIENS ON  RESTRICTED SUBSIDIARIES' CAPITAL STOCK.  Protective
Life  will  not, and  will not  permit  any Restricted  Subsidiary, at  any time
directly or  indirectly  to,  create,  assume, incur  or  suffer  to  exist  any
indebtedness secured by a pledge, lien or other encumbrance on the capital stock
of any Restricted Subsidiary without making effective provision for securing the
Notes then outstanding (and if Protective Life so elects, any other indebtedness
ranking  on  a parity  with the  Notes)  equally and  ratably with  such secured
indebtedness as to such  property for so  long as such  indebtedness will be  so
secured;  PROVIDED, HOWEVER, that this covenant  will not be applicable to liens
(as defined in the Indenture Supplement relating to the Notes) (i) on the shares
of stock of a subsidiary of a Person that is merged with or into Protective Life
or a Subsidiary securing debt of  such Person, which debt was outstanding  prior
to  such  merger,  but  only  if  such pledge  and  debt  were  not  incurred in
anticipation of such merger, (ii) in favor of Protective Life securing debt of a
Restricted Subsidiary owed to Protective Life, (iii) for taxes or assessments or
governmental charges or levies  not then due and  delinquent or the validity  of
which  are being contested, or (iv) created  by or resulting from any litigation
or legal proceeding being contested.
 
EVENTS OF DEFAULT
 
   
    Unless  otherwise  indicated  in  a  Pricing  Supplement,  the  Supplemental
Indentures  relating to the Notes will modify the Events of Default described in
the Prospectus by defining as one such Event of Default a default in payment  of
principal   relating  to  indebtedness  of  the  Company  and  its  consolidated
subsidiaries for  borrowed money  having an  aggregate principal  amount of  $15
million  or more, or other default  resulting in acceleration of indebtedness of
the Company  and its  consolidated  subsidiaries for  borrowed money  where  the
aggregate principal amount so accelerated equals or exceeds $15 million and such
acceleration  is  not rescinded  or annulled  within 30  days after  the written
notice thereof to the Company by the  Trustee or to the Company and the  Trustee
by  the  Holders  of  25%  in  aggregate  principal  amount  of  the  Notes then
outstanding; provided that  such Event  of Default  will be  remedied, cured  or
waived  if the default that  caused such Event of  Default is remedied, cured or
waived.
    
 
                CERTAIN UNITED STATES INCOME TAX CONSIDERATIONS
 
    The following  is a  summary of  certain United  States Federal  income  tax
consequences of the ownership of the Notes as of the date hereof. It is based on
the Code and final, temporary and proposed Treasury Regulations, Revenue Rulings
and judicial decisions, all as of the date hereof. It is also based upon certain
of  the  facts set  forth  in this  Prospectus  Supplement and  the accompanying
Prospectus and upon standard  procedures followed in  connection with the  offer
and sale of the Notes. This summary deals only with Notes held as capital assets
by their original purchasers who are United
 
                                      S-16
<PAGE>
States  Owners (as defined  below) and does not  address special tax situations.
This summary does not purport to cover all the possible tax consequences of  the
purchase,  ownership or disposition of the Notes,  and it is not intended as tax
advice to any  owner thereof. PERSONS  CONSIDERING THE PURCHASE  OR SALE OF  THE
NOTES  SHOULD CONSULT THEIR  OWN TAX ADVISORS CONCERNING  THE APPLICATION OF THE
INCOME TAX LAWS OF THE UNITED STATES, AS WELL AS THE LAWS OF ANY STATE, LOCAL OR
FOREIGN TAXING JURISDICTIONS, TO THEIR PARTICULAR SITUATIONS.
 
    Additional  United  States  Federal   income  and  other  tax   consequences
applicable  to  particular Notes  may  be set  forth  in the  applicable Pricing
Supplements.
 
    As used herein,  "United States Owner"  means a beneficial  owner of a  Note
which  is a United States person, and  "United States person" means a citizen or
resident of  the  United States,  a  corporation, partnership  or  other  entity
created  or organized in or under the laws of the United States or any political
subdivision thereof and an  estate or trust  the income of  which is subject  to
United  States Federal income taxation regardless of its source. "United States"
means the United  States of America  (including the States  and the District  of
Columbia),  its  territories,  its possessions  (including  the  Commonwealth of
Puerto Rico) and other areas subject to its jurisdiction.
 
PAYMENTS OF INTEREST
 
    In general, interest (including original issue discount, as discussed below)
on a Note will be treated as ordinary interest income to the United States Owner
of the Note at the time it accrues or is received, in accordance with the United
States Owner's  method  of accounting  for  tax purposes,  or,  in the  case  of
original  issue discount, specific United  States Federal income tax provisions.
The amount of original  issue discount or market  discount (as discussed  below)
which is includible in income in respect of a Note while held by a United States
Owner  will be added to such United States  Owner's tax basis for such Note, and
such basis will  be reduced by  any amortized acquisition  or other premium  (as
discussed  below) and amounts of other payments that do not constitute qualified
stated interest (as defined below).
 
SALE, EXCHANGE OR RETIREMENT OF THE NOTES
 
    A United States Owner  of a Note  will recognize gain or  loss on the  sale,
exchange  or retirement of such Note equal  to the difference between the amount
realized thereon and such owner's tax basis in the Note, which gain or loss will
generally be capital gain or loss (except to the extent of market discount  that
is  treated as having accrued) and will be  long-term capital gain or loss if at
the time of the  sale, exchange or  retirement the Note has  been held for  more
than  one  year. The  maximum rate  on  ordinary income  for taxpayers  that are
individuals, estates  or trusts  is  39.6 percent,  while  the maximum  rate  on
long-term  capital  gains  for such  taxpayers  is 28  percent.  The distinction
between capital gain or loss  and ordinary income or  loss is also relevant  for
purposes of limitations on the deductibility of capital losses.
 
ORIGINAL ISSUE DISCOUNT
 
    A  Note with an "issue price" that is less than its "stated redemption price
at maturity" will  generally be  considered to be  issued at  an original  issue
discount  for  United States  Federal income  tax purposes.  Generally, however,
under the "de  minimis exception,"  if the  difference between  a Note's  stated
redemption price at maturity and its issue price is less than .25 percent of the
stated  redemption price at maturity multiplied  by the number of complete years
from the  issue date  to  maturity, the  Note will  not  be considered  to  have
original  issue  discount. "Issue  price" is  defined  generally as  the initial
offering price to  the public at  which a substantial  amount of the  particular
issue  of  Notes  is sold.  "Stated  redemption  price at  maturity"  is defined
generally as  the  amount payable  on  an  obligation at  maturity,  except  for
payments  of  "qualified stated  interest," which  include, among  other things,
payments of stated interest that  are unconditionally payable or  constructively
received at least annually at a single fixed rate.
 
    If  the  period between  the issue  date of  a Note  and the  first interest
payment date  is longer  than the  periods between  subsequent interest  payment
dates, the Note will be a "long-period Note." Under
 
                                      S-17
<PAGE>
Treasury  Regulations issued on  January 27, 1994  (the "Original Issue Discount
Regulations"), a long-period Note  will not be  considered issued with  original
issue  discount if all stated interest on the Note is qualified stated interest.
If all stated  interest is not  qualified stated interest  because the  interest
rate  for  the long  period is  effectively  below the  rate applicable  for the
remainder of the Note's term, the Note will not have original issue discount  if
(i)  the value of the fixed interest rate is adjusted in "any reasonable manner"
(as discussed in the Original Issue  Discount Regulations) to take into  account
the length of the long period, or (ii) the de minimis exception discussed above,
with  certain  modifications, applies.  One of  these exceptions  will generally
apply to long-period Notes,  but if neither exception  applies, then such  Notes
will generally be treated as bearing interest at multiple fixed rates.
 
    If  interest is payable  on a Note  at multiple fixed  rates, then such Note
will provide for  qualified stated  interest only to  the extent  of the  lowest
fixed  rate at  which qualified stated  interest would be  payable. Any interest
payable in  excess of  this rate  will generally  be considered  original  issue
discount.
 
    United States Owners of Notes with original issue discount will generally be
required  to include original  issue discount in gross  income for United States
Federal income tax purposes as it  accrues, in accordance with a constant  yield
method  based on a  compounding of interest,  in advance of  receipt of the cash
payments attributable to  such income.  Such original  issue discount  generally
will  result in  the acceleration  of recognition  of ordinary  income to United
States Owners. Under  the constant yield  method, United States  Owners of  such
Notes  will  generally be  required to  include  in income  increasingly greater
amounts of original issue discount.
 
    Under the Original  Issue Discount  Regulations, a United  States Owner  may
elect to accrue all "interest" on a Note as original issue discount (I.E., using
the constant yield method discussed above). If a United States Owner elects this
method,  the Note's issue price  will be deemed to be  such owner's basis in the
Note at the time of its acquisition, and all of the payments on the Note will be
treated as included in its stated redemption price at maturity. This election is
available whether or not such a Note has original issue discount, and it applies
to any stated interest, original issue  discount (including discount that is  de
minimis)  and market discount (as discussed below) on a Note, all as adjusted by
any acquisition or other premium (as discussed below). This election may be made
on an obligation-by-obligation basis but, once  made on an obligation with  bond
premium,  it will operate as an election to amortize premium with respect to all
of such United States Owner's debt  instruments with premium, not just those  on
which  it is electing to apply the  constant yield method. A similar consistency
rule applies  to debt  instruments  with market  discount  and the  election  to
include such discount in income currently.
 
MARKET DISCOUNT AND PREMIUM
 
    If  a  United  States  Owner  purchases  a  Note  (including  a  purchase in
connection with  its original  issuance) for  an amount  that is  less than  its
"revised  issue price" (defined  as the sum of  the issue price  of the Note, as
defined above, and the aggregate amount, if any, of the original issue  discount
included,  without regard to the rules  for acquisition premium discussed below,
in the gross  income of  all previous  owners of the  Note), the  amount of  the
difference will be treated as "market discount" for United States Federal income
tax purposes, unless such difference is less than a specified de minimis amount.
Under the market discount rules, a United States Owner will be required to treat
any principal payment on, or any gain on the sale, exchange, retirement or other
disposition  of, a Note as ordinary income  to the extent of the market discount
which has  not previously  been included  in  income and  is treated  as  having
accrued  on such Note at  the time of such  payment or disposition. In addition,
the United States Owner may be required to defer, until the maturity of the Note
or its earlier disposition in a taxable  transaction, the deduction of all or  a
portion  of the  interest expense on  any indebtedness incurred  or continued to
purchase or carry such  Note. Any market discount  will be considered to  accrue
ratably  during the period from  the date of acquisition  to the Maturity of the
Note, unless  the United  States Owner  elects  to accrue  on a  constant  yield
method.  A United States Owner of a Note may elect to include market discount in
income   currently    as    it    accrues    (on    either    a    ratable    or
 
                                      S-18
<PAGE>
constant  yield  method),  in  which case  the  rule  described  above regarding
deferral of interest deductions will not apply. This election to include  market
discount  in  income  currently,  once  made,  applies  to  all  market discount
obligations acquired on or  after the first taxable  year to which the  election
applies,  and may  not be  revoked without the  consent of  the Internal Revenue
Service.
 
    A United States Owner that purchases a Note with original issue discount for
an amount  that is  greater  than the  Note's  "adjusted issue  price"  (defined
generally  as the issue price  of the Note increased  by the aggregate amount of
original issue discount includible, if any, in the gross income of all  previous
owners of the Note and decreased by the aggregate amount of payments made on the
Note,  if any, other than  payments of qualified stated  interest) but less than
the sum of all amounts payable on  the Note after the purchase date (other  than
payments of qualified stated interest) will be considered to have purchased such
Note  at an  "acquisition premium." The  amount of original  issue discount such
owner must include in its gross income with respect to such Note for any taxable
year will  be  reduced by  the  portion  of such  acquisition  premium  properly
allocable to such year.
 
    If  a United States Owner acquires a Note for an amount that is greater than
both its revised  issue price and  the sum of  all amounts payable  on the  Note
after the purchase date (other than payments of qualified stated interest), such
owner  will be considered  to have purchased  such Note at  a premium, such Note
will have no original issue discount, and such owner may elect to amortize  such
premium  using a constant yield method, generally over the remaining term of the
Note. Such  premium  shall be  deemed  to be  an  offset to  interest  otherwise
includible in income in respect of such Note.
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
    A  31-percent  "backup" withholding  tax  and certain  information reporting
requirements may apply to  certain payments to certain  United States Owners  of
principal  of and interest  (including original issue discount,  if any) on, and
proceeds of  the sale  or exchange  before maturity  of, a  Note. Under  current
Treasury  Regulations,  backup withholding  and  information reporting  will not
apply to payments  on the  Notes made  by Protective  Life or  any paying  agent
thereof  (in its capacity as such) to exempt recipients, such as corporations or
financial institutions, but  such entities  may be required  to establish  their
status  as  such. Under  current  Treasury Regulations,  backup  withholding and
information reporting also will not apply to  payments on the Notes made by  any
custodian, nominee or other agent of a United States Owner, or to the payment of
the  proceeds of a sale or exchange of a  Note made to a United States Owner, if
such payments or proceeds are paid to exempt recipients such as corporations  or
financial  institutions, but  such entities may  be required  to establish their
status as such. In the case of a United States Owner that has not established an
exemption from information  reporting and  backup withholding  (for example,  an
individual),  backup  withholding  will  not be  applicable  if  such  owner has
supplied an accurate Taxpayer  Identification Number, has  not been notified  by
the  Internal Revenue Service that it has  failed to report properly payments of
interest and  dividends  and,  in certain  circumstances,  has  certified  under
penalties  of perjury that it has received  no such notification and that it has
supplied an accurate Taxpayer Identification Number. Any amounts withheld  under
the  backup withholding rules from a payment to  a United States Owner of a Note
will be allowed  as a  refund or  a credit  against such  owner's United  States
Federal  income tax, provided that any  required information is furnished to the
Internal Revenue Service.
 
    On April 15, 1996, the Internal Revenue Service issued proposed  regulations
on  backup  withholding  and  certain  information  reporting  requirements.  If
finalized in their current  form, those regulations would  apply to payments  on
Notes  made after December  31, 1997, including  payments on Notes  issued on or
before that date. In general,  the proposed regulations would not  significantly
alter  the present rules discussed above,  except in certain special situations.
Accordingly, owners  of  Notes should  consult  their  tax advisors  as  to  the
potential impact of the proposed regulations on their particular situations.

                              PLAN OF DISTRIBUTION
 
   
    The  Notes are being offered  on a continuing basis  for sale by the Company
through the Agent,  which has agreed  to use its  reasonable efforts to  solicit
offers  to purchase the Notes, and the Company may also sell Notes to the Agent,
as principal, for  resale to investors  and other purchasers  at varying  prices
related  to prevailing market prices at the time of resale, as determined by the
Agent, or, if  so agreed, at  a fixed  public offering price.  In addition,  the
Company  may arrange  for the Notes  to be  sold through other  agents, may sell
Notes directly on its own behalf and  may solicit and accept offers, and  accept
unsolicited  offers, to purchase  Notes directly on  its own behalf  or from any
other broker or dealer.  The Company reserves the  right to withdraw, cancel  or
modify the offer made hereby without notice and may reject offers to purchase in
whole  or in part whether placed directly with the Company or through the Agent.
The Agent will have the right, in its discretion, to reject in whole or in  part
any  offer to purchase Notes received by it.  The Company will pay the Agent, in
the form of a discount or otherwise, a commission, ranging from 2.5% to 3.5%  of
the  principal amount of  a Note, depending on  its Stated Maturity. Commissions
with respect to Notes with a Stated Maturity in excess of 30 years from the date
of issue which are sold through the Agent  will be agreed to by the Company  and
the Agent at the time of such sale.
    
 
    In  addition, the Agent may offer the Notes it has purchased as principal to
other dealers for resale to investors and may allow to such dealers any  portion
of  the discount received  by the Agent  for the Company  in connection with the
sale of  such  Notes.  Unless  otherwise indicated  in  the  applicable  Pricing
Supplement,  any Notes sold to  the Agent as principal  will be purchased by the
Agent at a price equal to 100% of the principal amount thereof less a percentage
equal to the commission as  described above applicable to  any agency sale of  a
Note  with  an identical  Stated Maturity,  and may  be resold  by the  Agent to
investors and other purchasers from time to time in one or more transactions  as
described above. After the initial public offering of Notes, the public offering
price  (in the case of Notes to be  resold on a fixed offering price basis), the
concession and discount may be changed.
 
    Unless otherwise specified in the applicable Pricing Supplement, payment  of
the  purchase price  of the  Notes will  be required  to be  made in immediately
available funds in New York City on the date of settlement.
 
    No Note will  have an  established trading  market when  issued, and  unless
otherwise  specified in an applicable Pricing  Supplement, the Notes will not be
listed on any securities exchange. The Agent may from time to time purchase  and
sell Notes in the secondary market, but the Agent is not obligated to do so, and
there can be no assurance that there will be a secondary market for the Notes or
liquidity  in the secondary market if one develops. From time to time, the Agent
may make a market in the Notes.
 
    The Agent may be  deemed to be  an "underwriter" within  the meaning of  the
Securities  Act of 1933, as amended (the  "Securities Act"). The Company and the
Agent have agreed to indemnify each other against certain liabilities, including
liabilities under  the Securities  Act, or  to contribute  to payments  made  in
respect  thereof. The Company has also agreed to reimburse the Agent for certain
expenses.
 
    In the ordinary course of business,  the Agent or certain of its  affiliates
have  in the past  engaged in or  provided, and may  in the future  engage in or
provide, investment banking or brokerage  transactions with or services for  the
Company  or its subsidiaries.  In addition, in the  ordinary course of business,
the Agent or certain of its affiliates have  in the past marketed and sold on  a
regular  basis, and may in the future  market and sell, certain of the Company's
insurance products, including individual life, term life and fixed and  variable
annuity products.
 
    Concurrently  with  the offering  of Notes  through  the Agent  as described
herein, the Company may issue other Debt Securities pursuant to the Indenture.

Protective  Life's methods  of accounting for  stock-based employee compensation

    With  respect to the unaudited  interim financial information for Protective
Life and Subsidiaries for  the nine-month periods ended  September 30, 1996  and
1995  incorporated by reference  in this Prospectus  Supplement, 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 Supplement 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 independent
accountants are not  subject to the  liability provisions of  Section 11 of  the
Securities  Act with respect to 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 Securities Act.

                         ------------------------------
 
    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
of  the Common Stock in respect of which this Prospectus is being delivered will
not exceed U.S. $75,000,000.
 
    PLC Capital, a limited liability company formed under the laws of the  State
of  Delaware,  was  formed by  Protective  Life  solely to  issue  its Preferred
Securities, representing preferred limited liability company interests, and  its
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

                          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:
 
                                       3
<PAGE>
(205) 879-9230).  Protective Life  owns,  directly and  indirectly, all  of  the
Common  Securities of PLC 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

any  Event  of Default  or  any covenant  of  Protective Life  specified  in the
Indenture with respect to such Debt Securities; (17) the application, if any, of
such means of  defeasance or covenant  defeasance as may  be specified for  such
Debt  Securities; (18) whether such Debt Securities are to be issued in whole or
in part in the form of one or more temporary or permanent global securities and,
if so, the identity  of the depository for  such global security or  securities;
(19)  in the case of  the Subordinated Indenture, the  terms, if any, upon which
such Debt Securities may be converted or exchanged, at the option of the holders
thereof, into or  for Common  Stock of Protective  Life or  other securities  or
property;  and  (20) any  other terms  not  inconsistent with  the terms  of the
Indentures pertaining to such Debt Securities. (Section 3.1 of each  Indenture.)
Unless  otherwise specified  in the  applicable Prospectus  Supplement, the Debt
Securities will not be listed on any securities exchange.
 
    Unless otherwise  specified in  the applicable  Prospectus Supplement,  Debt
Securities  will be issued in fully-registered  form without coupons. Where Debt
Securities of any series are issued in bearer form, the special restrictions and
considerations, including  special  offering restrictions  and  special  federal
income tax considerations, applicable to any such Debt Securities and to payment
on  and transfer and exchange  of such Debt Securities  will be described in the
applicable Prospectus Supplement. Bearer Debt Securities will be transferable by
delivery. (Section 3.5 of each Indenture.)
 
    Debt Securities may  be sold at  a substantial discount  below their  stated
principal amount, bearing no interest or interest at a rate which at the time of
issuance  is below  market rates.  Certain federal  income tax  consequences and
special considerations applicable to any such Debt Securities will be  described
in the applicable Prospectus Supplement.
 
    If  the purchase price  of any of the  Debt Securities is  payable in one or
more foreign  currencies  or  currency  units or  if  any  Debt  Securities  are
denominated  in  one or  more foreign  currencies  or currency  units or  if the
principal of, premium, if any,  or interest, if any,  on any Debt Securities  is
payable  in one or more foreign  currencies or currency units, the restrictions,
elections, certain federal
 
                                       6
<PAGE>
income tax considerations, specific terms and other information with respect  to
such  issue of Debt Securities and such  foreign currency or currency units will
be set forth in the applicable Prospectus Supplement.
 
    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
made (i) by checks mailed to the holders of Debt Securities entitled thereto  at
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
 
                                       7
<PAGE>
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  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
 
                                       8
<PAGE>
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.
 
    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
 
                                       9
<PAGE>
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 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
 
                                       10
<PAGE>
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.)
 
    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
 
                                       11
<PAGE>
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.)
 
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
 
                                       12
<PAGE>
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.
 
    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
 
                                       13
<PAGE>
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 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
of each Indenture)
 
TITLE
 
    Protective Life, the Trustee and any agent of Protective Life or the Trustee
may treat the Person in whose name a Debt Security is registered as the absolute
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
Indenture)
 
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
and  their affiliates in the ordinary course of business. The Indentures contain
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.

    In general, the classes of authorized capital stock are afforded preferences

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

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

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

    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,
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
 
                                       16
<PAGE>
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 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
 
                                       17
<PAGE>
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 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 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
 
                                       19
<PAGE>
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.
 
    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
 
                                       20
<PAGE>
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 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.
 
                                       21
<PAGE>
    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. 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
 
                                       22
<PAGE>
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.
 
    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
 
                                       23
<PAGE>
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.
 
    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.

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
