                                    SUMMARY
   
THESE PAGES CONTAIN A BRIEF SUMMARY OF SOME OF THE IMPORTANT FEATURES OF THE
SYSTEMATIC INVESTMENT PLAN AND VARIABLE ANNUITY CONTRACTS DESCRIBED IN THIS
PROSPECTUS, PARTICULARLY THOSE RELATED TO THE CHARGES MADE BY PRUDENTIAL. THIS
SUMMARY DOES NOT PROVIDE A FULL DESCRIPTION OF THE CONTRACTS. THE ENTIRE
PROSPECTUS SHOULD BE READ FOR THAT PURPOSE. YOU MAY FIND IT HELPFUL TO RE-READ
THIS SUMMARY AFTER YOU HAVE READ THE PROSPECTUS.     
   
This Prospectus describes several variable contracts issued by The Prudential
Insurance Company of America (Prudential). These Contracts include a
Systematic Investment Plan Contract and an individual Variable Annuity
Contract. For each Contract, one form, which has been amended several times
since it was first offered in 1970, is called the Old Form Contract in this
Prospectus. This Prospectus also describes revised forms of these Contracts,
which were first offered to the public on September 17, 1973.     
   
The two forms of each Contract are similar in many respects; and since the
revised Contracts were issued more widely, they are the ones generally
described in this Prospectus. Whenever there is a difference between the Old
Form and the revised Contracts, however, this will be noted or a reference
will be made to the section entitled DIFFERENCES UNDER OLD FORM CONTRACTS,
page 28. That section details how the Old Form Contracts, and the Program of
which they are a part, differ from the revised Contracts and Program. Old Form
Contracts can be identified by the letter A appearing as the 7th digit (and
only letter) in the plan number. Revised Contracts contain the letter B in
that spot.     
 
The revised Contracts were issued in all states. However, all persons who
purchased and still hold Old Form Contracts may continue to make additional
purchase payments in accordance with the provisions of those Contracts.
Persons holding Old Form Contracts may, under certain circumstances, exchange
them for revised Contracts. In such cases, any annuities effected prior to the
exchange would continue to be governed by the annuity payout provisions of the
Old Form Contract.
   
The net purchase payments made under the Systematic Investment Plan and
Variable Annuity Contracts, after the deductions described below, are
allocated to Prudential's Investment Plan Account and Prudential's Annuity
Plan Account, respectively. The assets of both Prudential's Investment Plan
Account and Prudential's Annuity Plan Account (the Accounts) are invested at
net asset value in shares of Prudential's Gibraltar Fund, Inc. (the Fund). The
value of interests in the Accounts will increase or decrease depending on
increases or decreases in the market value of the portfolio securities owned
by the Fund.     
   
The Fund was organized by Prudential to serve as the investment medium for the
variable contract accounts of the Prudential Financial Security Program (the
Program), including these Accounts. The Fund does not sell its shares to the
public. It is registered under the Investment Company Act of 1940, as amended,
as a diversified open-end management investment company whose investment
objective is concerned primarily with growth of capital to an extent
compatible with a concern for its preservation. Current income is a secondary
consideration. The portfolio of the Fund consists primarily of common stock of
a diversified group of companies in a variety of industries. The Contracts are
subject to the risks associated with common stock investment, so there can be
no assurance that the investment objectives will be achieved. Investment
policies of the Fund permit investments in three categories that could entail
special risks: the Fund's assets may be invested in American Depository
Receipts; up to 10% of the value of the Fund's assets may be invested in
securities which are not readily marketable; and up to 3% may be invested in
warrants or rights to acquire stock. See SPECIAL RISKS, page 21. Of course,
the Contracts described in this Prospectus will not necessarily provide an
individual with financial security.     
   
Prudential is a mutual insurance company, founded in 1875 under the laws of
New Jersey. Prudential is subject to regulation by the Department of Insurance
of the State of New Jersey and by the insurance departments of all the other
states and jurisdictions in which it does business. Prudential is the
investment advisor of the Fund. See PRUDENTIAL AS MANAGER OF THE FUND'S
INVESTMENTS, page 23. Prudential's financial statements begin on page D1 and
should be considered only as bearing upon Prudential's ability to meet its
obligations under the Contracts.     
   
Pruco Securities Corporation (Prusec), an indirect wholly-owned subsidiary of
Prudential, acts as the principal underwriter of the Fund and the Accounts.
Prusec's principal business address is 751 Broad Street, Newark, New Jersey
07102-3777. Subject to Board approval, during the second quarter of 1998,
Prusec's responsibilities as principal underwriter will be assigned to
Prudential Investment Management Services LLC (PIMS). PIMS, also an indirect
wholly-owned subsidiary of Prudential, is a limited liability corporation
organized under Delaware law in 1996. PIMS will act as principal underwriter
under substantially the same terms as Prusec does currently. Both Prusec and
PIMS are registered as broker-dealers under the Securities Exchange Act of
1934, as amended, and are members of the National Association of Securities
Dealers, Inc. PIMS' principal business address is 751 Broad Street, Newark,
New Jersey 07102-3777.

<PAGE>
 
                        THE SYSTEMATIC INVESTMENT PLAN
   
SALES AND CUSTODIAL CHARGES. The sales charge ranges from 8.50% on the first
$5,000 to 0.60% on any excess over $500,000. After deduction of the sales
charge and a $1 custodial charge, the net amount invested is allocated to
Prudential's Investment Plan Account and is credited to the Planholder in
terms of a number of units known as Systematic Investment Plan Shares (SIP
Shares). (Under Old Form Contracts such units are known as Securities Shares.)
After the initial purchase payment to provide SIP Shares for "any person," as
defined under SALES AND RELATED CHARGES on page 10, the sales charge rate for
subsequent Systematic Investment Plan purchases is determined by adding to the
amount of each such purchase payment the total value of the SIP Shares already
credited. For a minimum $50 purchase payment, the maximum sales charge and the
maximum deduction from purchase payment (including sales charge and custodial
charge) are 9.5% and 11.73%, respectively, of the net amount invested. See
SALES AND RELATED CHARGES, page 10, and DIFFERENCES UNDER OLD FORM CONTRACTS,
page 28.     
   
The Planholder under the revised Contract may complete a Letter of Intent
indicating an intention, without obligation, to make SIP Share purchase
payments totaling at least $10,000 over a 13-month period. In this case, the
sales charge rate for each purchase made to fulfill the Letter of Intent will
be determined as if the total amount indicated were made as a single purchase
payment on the first business day of the 13-month period. See LETTER OF
INTENT, page 11.     
   
OTHER CHARGES. The charges just described are made in connection with purchase
payments. In addition, other charges are made daily against the assets of
Prudential's Investment Plan Account and the Fund. These are an administration
charge applied against Account assets at a rate of 3/4 of 1% (0.75%) per year
and an investment advisory charge applied against the Fund assets underlying
the Account at a rate of 1/8 of 1% (0.125%) per year. In total these charges
represent on a yearly basis approximately 7/8 of 1% (0.875%) of the net assets
of the Account. In addition, the Fund has expenses which may be considered to
be an indirect charge against assets. See SUMMARY OF INVESTMENT ADVISORY
CONTRACT, page 22.     
   
An annual custodial charge of $0.95 per quarter is made for each Planholder.
This charge, for a continuing Planholder, will be deducted from and will not
exceed the amount of net investment income and capital gains distribution
remaining after any other deduction from that distribution. This other
deduction is, if SIP Share purchases were made since the previous
distribution, a one-time charge of $0.25 per right for any annuity rate
protection rights required to be bought in connection with those purchases.
See ANNUITY RATE PROTECTION, page 12. Planholders may liquidate their SIP
Share interests totally or in part at any time. A transaction charge is made
upon each liquidation, except when the proceeds of a total or partial
liquidation of SIP Shares are used to provide a variable annuity under the
Program. The amount of this transaction charge is $1, or 1% of the net amount
liquidated if less. See OTHER CHARGES, page 11, DIFFERENCES UNDER OLD FORM
CONTRACTS, page 28, and LIQUIDATION (REDEMPTION) OF SIP SHARES, page 13.     
 
ILLUSTRATION. To illustrate how the sales and other charges may operate over
the year, assume that a person opens a Systematic Investment Plan for an
initial purchase of $2,500. An 8 1/2% sales charge ($212.50) and $1 custodial
charge are deducted from the purchase payment, leaving $2,286.50 as the net
amount to be invested. If the share value for that business day is $10, this
will result in 228.65 shares being credited to the Planholder ($2,286.50 /
$10). If there should be no daily change in the SIP Share Value during the
ensuing year, the total charges against assets for the year would be
approximately $20.01.
 
Assume that these shares remain credited to the Planholder for the year and
participate in a distribution of net investment income at the end of the year.
If the distribution is $0.20 a share, this Planholder's share of the
distribution will amount to $45.73 ($0.20 X 228.65 shares). From this amount
the charge for the annuity rate protection rights, $6.25 ($0.25 X 25, assuming
1 Right per $100) and for the annual custodial charge, $3.80 ($0.95 X 4) are
deducted leaving a balance of $35.68 to be reinvested, without sales charge,
to increase the number of the SIP Shares credited to the Planholder.
 
                         THE VARIABLE ANNUITY CONTRACT
   
SALES CHARGES. For a variable annuity purchased with funds which are not
derived from a liquidation of SIP Shares, the sales charge ranges from 8.50%
on the first $5,000 of purchase payment after deduction of any applicable
premium tax to 0.60% on the excess over $500,000. In determining what sales
charge rate applies, all purchase payments, whenever made, for annuities under
the Program on the life of the Planholder, his/her spouse and his/her children
below age 21, are added together. This is illustrated in the paragraph headed
ACCUMULATION OF PURCHASES on page 15.     
 
                                       3
<PAGE>
 
   
For purchases made with the proceeds of the liquidation of SIP Shares, the
sales charge is 1.5% on the first $5,000 of such proceeds and lower for
aggregated payments exceeding $5,000. If a Planholder makes a minimum variable
annuity purchase using the liquidation proceeds of SIP Shares acquired by a
series of minimum purchases, and if there was no change in the SIP Share Value
after the initial purchase, this sales charge, together with the sales and
custodial charges for the SIP Share purchases and the cost of the annuity rate
protection rights, would total approximately 11.8% of the SIP purchase
payments.     
   
Some of the states impose a premium tax, which ranges from 1% to 5% of the
purchase payment or on the value of the account upon annuitization, depending
on the jurisdiction. The sales charges and state premium taxes are discussed
in greater detail in the section SALES AND OTHER CHARGES on page 15.     
   
OTHER CHARGES. The charges described above are made in connection with
purchase payments. In addition, other charges are made daily against the
assets of Prudential's Annuity Plan Account and the Fund. The charges applied
against Account assets held for the benefit of contracts participating in the
Account are for administrative services and for the assumption by Prudential
of mortality and expense risks. These charges are made at an aggregate rate of
0.375% per year. Considering the investment advisory charge applied against
Fund assets, these other charges, exclusive of premium taxes and sales
charges, in total, represent on a yearly basis approximately 1/2 of 1% (0.5%)
of the net assets of the Account. See SALES AND OTHER CHARGES, page 15.     
   
CANCELLATION. A variable annuity may be canceled no later than the date of
commencement of annuity payments. It may not be canceled after annuity
payments begin. The termination value paid on cancellation is equal to the net
amount which was required to provide the annuity, adjusted for interest and
changes in the annuity share value. If a state premium tax was deducted from
the purchase payment, the amount of the tax or a portion of it may, in certain
cases, be returned. See CANCELING THE ANNUITY, page 19.     
   
FUTURE CHANGES IN CHARGES AND ANNUITY RATES. Prudential reserves the right,
under certain conditions, to change all charges, including sales charges and
annuity rates, upon 90 days' notice to Planholders. However, it may not change
annuity rates applicable upon the exercise of annuity rate protection rights
already purchased. See Changing the Contract, page 28, and Annuity Rate
Protection, page 12.

                          GENERAL PROGRAM INFORMATION
 
THE CONTRACTS OF THE PRUDENTIAL FINANCIAL SECURITY PROGRAM
   
The Program consists of a number of contracts offered by Prudential, a mutual
life insurance company organized in 1875 under the laws of the State of New
Jersey. Its corporate office is located at 751 Broad Street, Newark, New
Jersey 07102-3777. The Contracts are sold by registered representatives of
Prusec, an indirect wholly-owned subsidiary of Prudential with a principal
business address at 751 Broad Street, Newark, New Jersey 07102-3777. It was
organized in 1971 under New Jersey law, is registered as a broker and dealer
under the Securities Exchange Act of 1934, as amended (the 1934 Act), and is a
member of the National Association of Securities Dealers, Inc. (the NASD).
Prusec currently acts as principal underwriter of the Contracts, however,
subject to Broad approval.     
   
Prusec's responsibilities as principal underwriter will be assigned to PIMS
during the second quarter of 1998. PIMS, also an indirect wholly-owned
subsidiary of Prudential, is a limited liability corporation organized under
Delaware law in 1996. PIMS will act as principal underwriter under
substantially the same terms as Prusec does currently. PIMS is registered as a
broker-dealer under the 1934 Act and is a member of the NASD. PIMS' principal
business address is 751 Broad Street, Newark, New Jersey 07102-3777.     
   
The Contracts include a Systematic Investment Plan Contract to accumulate
funds, an Annuity Rate Protection Contract, and a Variable Annuity Contract to
provide retirement payments you cannot outlive. The Systematic Investment Plan
and Variable Annuity Contracts are described briefly in the following
paragraphs and in detail beginning on page 3. Annuity Rate Protection provides
for interests, which are called Rights, to be acquired in connection with the
acquisition of Systematic Investment Plan interests. It is described on page
12. Also see DIFFERENCES UNDER OLD FORM CONTRACTS, page 28.     
   
The mailing address of the office which services these Contracts is The
Prudential Insurance Company of America, 751 Broad Street, Newark, New Jersey
07102-3777. Prudential is registered as an investment adviser under the
Investment Advisers Act of 1940, as amended.     
   
Net purchase payments under the Plan are credited in terms of units known as
SIP Shares in Prudential's Investment Plan Account. See PURCHASE PAYMENTS AND
THE CREDITING OF SIP SHARES, page 9. A person in whose name purchases are made
under the Plan, or under the Variable Annuity Contracts of the Program, is
known as a Planholder. Systematic investment does not, of course, assure a
profit from your investment or growth equal to the sales charge paid, or
protect you against loss in a declining market.     
   
(Units credited to the Plan under Old Form Contracts are known as Securities
Shares rather than SIP Shares. However, what is said of SIP Shares throughout
this Prospectus will generally apply to Securities Shares, except where
specifically noted. In such cases any differences are either described at the
time or by reference to DIFFERENCES UNDER OLD FORM CONTRACTS, page 28.
Securities Shares and SIP Shares are equal in value.)     
 
Net purchase payments under the Variable Annuity Contract are allocated to
Prudential's Annuity Plan Account. The variable annuities effected under the
Contract provide monthly payments for life. Annuity payments ordinarily begin
soon after a variable annuity is purchased, but a Planholder for whom an
annuity is purchased may defer the commencement of payments for up to three
years. The amount of each variable annuity payment varies depending on the
investment results of a designated portfolio consisting primarily of common
stocks. The amount of each payment is, therefore, subject to market
fluctuations and in declining markets is likely to be lower than earlier
payments.
 
PRUDENTIAL'S INVESTMENT PLAN AND ANNUITY PLAN ACCOUNTS
   
These Accounts were established on June 11, 1968, by resolution of
Prudential's Board of Directors, as separate variable contract accounts of
Prudential under the laws of the State of New Jersey. They are administered by
Prudential under the general direction of Prudential's officers and managerial
staff. The Accounts are registered with the Securities and Exchange Commission
under the Investment Company Act of 1940, as amended (1940 Act), as unit
investment trusts. Registration does not imply supervision by the Securities
and Exchange Commission of the management or investment policies and practices
of the Accounts or Prudential.     
   
IPA is currently used only in connection with Prudential's Systematic
Investment Plan Contracts. Similarly, APA is now used only in connection with
the individual Variable Annuity Contracts described in this Prospectus. The
assets in each Account are legally segregated from all other assets of
Prudential and, in APA, such assets will always be equal to or greater in
value than Prudential's liabilities under the Variable Annuity Contracts,
calculated in accordance with sound actuarial principles. The assets of both
Accounts are invested in shares of the Fund at net asset value without sales
load.     
 
                                       7

PRUDENTIAL'S GIBRALTAR FUND, INC.
   
The Fund was originally incorporated in the State of Delaware on March 14,
1968 and was reincorporated in the State of Maryland effective May 1, 1997. It
is registered under the 1940 Act as a diversified open-end management
investment company. Registration does not imply supervision by the Securities
and Exchange Commission of the management or investment policies and practices
of the Fund or Prudential. The Board of Directors of the Fund is responsible
for the management of the Fund and, in addition to reviewing the actions of
the Fund's investment advisor, decides upon matters of general policy. The
Fund's officers conduct and supervise the daily business operations of the
Fund.     
 
The Fund's portfolio, which is set forth on pages C2 and C3, is composed
primarily of common stocks of a diversified group of companies in a variety of
industries. The investment objective of the Fund is concerned primarily with
growth of capital to an extent compatible with a concern for its preservation.
Current income is a secondary consideration.
 
The investments of the Fund are subject to the risks of changing economic
conditions and the ability of management and the investment advisor of the
Fund to anticipate such changes. There can be no assurance that the Fund's
investment aims will be achieved.
   
Fund shares are sold only to separate accounts of Prudential including IPA and
APA. The investment performance of the Fund determines the dollar value of
interests in these accounts.     
   
Prudential is the investment advisor to the Fund. Prudential has entered into
a service agreement with its wholly-owned subsidiary, The Prudential
Investment Corporation (PIC), which provides that PIC will furnish to
Prudential such services as Prudential may require in connection with
Prudential's performance of its obligations under advisory agreements with
clients which are registered investment companies. For its investment advisory
services, Prudential is paid 1/8 of 1% (0.125%) per year of the average daily
market value of the Fund's net assets ($1.25 per year for each $1,000 of
assets). The Fund paid Prudential $390,676 for these services in 1997 and
$349,118 in 1996. In addition, the Fund has expenses which may be considered
to be an indirect charge against assets. In 1997 these expenses amounted to
0.025% of average net assets of the Fund and in 1996 these expenses were
slightly less than 0.035%. See SUMMARY OF INVESTMENT ADVISORY CONTRACT on page
22, PRUDENTIAL AS MANAGER OF THE FUND'S INVESTMENTS on page 23, AND FINANCIAL
STATEMENTS OF PRUDENTIAL'S GIBRALTAR FUND, INC. and NOTES TO FINANCIAL
STATEMENTS on pages C1 through C5. For the years ended December 31, 1997 and
1996, the Fund's total expenses were 0.15% and 0.16%, respectively, of the
Fund's average net assets.     
   
INVESTMENT RESULTS. The financial highlights table on page 6 shows the net
asset value together with operating expense and net investment income ratios,
and total investment rate of return for the years indicated.     
   
PRUDENTIAL'S ADMINISTRATIVE ROLE     
   
Prudential acts as transfer agent and dividend-paying agent and performs all
administrative services relative to the Contracts and necessary to the
operation of the Accounts. The Accounts have no officers or employees.
Prudential pays all expenses relating to their operation.     
   
For IPA and the Systematic Investment Plan Contracts, many of the bookkeeping
and other administrative services are performed by Prudential in accordance
with an agreement between Prudential and the Custodian for the Account, in
compensation for which Prudential receives the charges described under the
heading OTHER CHARGES on page 11. Also see CUSTODIAN FOR PRUDENTIAL'S
INVESTMENT PLAN ACCOUNT, page 26. These services include:     
 
(1) maintaining a record of all transactions relating to the crediting,
    liquidation and transfer of shares under the Systematic Investment Plan;
 
(2) furnishing notices of the number of shares credited, liquidated or
    transferred, and the number of shares standing to the credit of each
    Planholder;
   
(3) furnishing copies of the prospectus and of periodic reports of the
    financial condition of Prudential's IPA and of Prudential's Gibraltar
    Fund, Inc. (or any other fund or funds substituted therefor);     
 
(4) furnishing net investment income and capital gains statements and any
    pertinent tax notices;
   
(5) causing the required audit of the books of Prudential's IPA; and     
   
(6) preparing and filing for Prudential's IPA required Federal and State
    periodic statements and tax reports.     
 
                                       8
<PAGE>
 
   
Prudential performs similar administrative services, as applicable, for APA
and the Variable Annuity Contracts. In addition, it holds the assets of APA
for safekeeping, and performs such additional services for both IPA and APA as
accounting for the assets in the Accounts, applying payments made for the
purchase of SIP Shares or variable annuities after making the authorized
deductions, making liquidation and annuity payments and furnishing voting
material.     
   
In addition to the Plan charges discussed under OTHER CHARGES on page 11,
those discussed under SALES AND RELATED CHARGES on page 10 and the variable
annuity charges discussed under SALES AND OTHER CHARGES on page 15 compensate
Prudential for its services.     
 
                 DESCRIPTION OF THE SYSTEMATIC INVESTMENT PLAN
   
WHAT THE PLAN IS AND DOES     
   
The Plan provides the Planholder with a means of investing funds for possible
growth. The Planholder may make a single purchase, make occasional investments
of varying amounts from time to time, invest regular amounts periodically
according to his/her own schedule, or employ any combination of these
investment patterns. ANNUITY RATE PROTECTION described on page 12, which is
acquired in respect to each purchase under the Plan, permits the Planholder to
use his/her Plan interests at a later time to obtain variable annuity payments
based upon a guaranteed schedule of rates.     
 
PURCHASE PAYMENTS AND THE CREDITING OF SIP SHARES
   
The minimum initial purchase payment for a Planholder under the Plan is $300.
For subsequent purchases under that Plan the minimum payment is $50. However,
under certain arrangements for periodic purchases on a regular basis, such as
deferred compensation plan arrangements for employees of federal, state or
municipal agencies, the minimum amount for both initial and subsequent
purchase payments is $50. In addition to the normal investment risk, deferred
compensation plan arrangements may involve the risk of the employer's future
unwillingness or financial or administrative inability to continue the plan.
For minimum purchase requirements under Old Form Contracts, see DIFFERENCES
UNDER OLD FORM CONTRACTS on page 28.     
   
From each Plan purchase payment made for the Planholder, the sales charge and
custodial charge described under SALES AND RELATED CHARGES, page 10, will be
deducted. The remainder is the net amount invested and is used to determine
the number of SIP Shares credited. That number is determined by dividing the
net amount invested by the net asset value per Share (Share Value).     
   
The Share Value for any business day (a day on which the New York Stock
Exchange, Inc. (NYSE) is open for business) is determined as of the end of
such day and is equal to the net assets of Prudential's IPA divided by the
aggregate number of Shares credited under the Account. The net assets of the
Account are its total assets (after establishing any liability for
distributions to Planholders) reduced by the liability for transfer taxes, if
any, and by the administration charge described under the heading OTHER
CHARGES on page 11. Since the assets of the Account are invested in shares of
the Fund, the value of SIP Shares will vary as a reflection of the investment
experience of the Fund.     
   
Crediting of SIP Shares will be effected at the close of the day on which the
purchase payment is received at Prudential, if that is a business day,
otherwise at the close of the first business day thereafter.     
 
SIP Shares are not evidenced by the issuance of certificates. Instead, after
each purchase payment is made under the Plan, the Planholder will receive a
notice that will indicate the number of SIP Shares credited to the Planholder
as a result of that payment, the price per Share and the total number of SIP
Shares then standing to the Planholder's credit.
   
Shown below are Share Values under the Plan as of the last business day of
each year of the 10 year period ending December 31, 1997. Also shown for each
date are the total number of Shares then outstanding, and the amount per Share
of any investment income and capital gains distributions declared during the
year ending on that date, before any deductions which may be made from such
distributions as described on page 14 under DISTRIBUTIONS. The remainder of
the distributions after any such deductions were reinvested at net asset value
to provide additional shares unless cash payment was requested by the
Planholder.

* Without taking into account deduction for any premium tax.
   
The scale of sales charges is applicable to purchase payments to acquire SIP
Shares made at one time by "any person." "Any person" is defined as either (1)
an individual Planholder, or that Planholder, his/her spouse if also a
Planholder and their children below age 21 who are Planholders, provided in
any case that the purchase is being made for one of these Planholders, or (2)
a trustee or other fiduciary purchasing, subject to Prudential's rules
regarding participation in the Program through a fiduciary, for a single trust
estate or fiduciary account, even if more than one beneficiary Planholder is
involved.     
 
After the initial purchase payment, the sales charge rate for subsequent
purchases under the Plan is determined by adding to the combined total of the
purchase payments then being made by "any person," the total value of SIP
Shares already credited to such persons. For example, a Planholder submits a
purchase payment of $5,000. As of the current purchase date the Planholder and
spouse, who is also a Planholder, already are credited with SIP Shares with a
total value of $10,000. When the $5,000 is added to the $10,000, it can be
seen from the table at the beginning of this section that the sales charge
rate applicable to the current $5,000 purchase is 5%. The amount of the sales
charge on the current purchase is, therefore, $250.
 
Reduced sales charges are also available to "any person" through a Letter of
Intent. This is described in the following section.
   
Full-time registered sales representatives of Prudential, and retired sales
representatives of Prudential who have retained their sales licenses and
registered status with Prudential, may make purchases under their Plan
Contracts at net asset value without sales charge. These representatives must
provide written assurance that their purchases will be made for their personal
investment purposes and that the interests acquired under the Contracts will
not be transferred to another person.     
 
A $1 custodial charge is deducted from each purchase payment to cover the
custodial and administrative services connected with receipt of money and
crediting of SIP Shares.
 
                                      10
<PAGE>
 
For initial purchase payments of $300 and $10,000, for example, the sales
charge is 9.32% and 8.40%, respectively, of the net amount that will be
invested in the Account, after deducting payment of the $1 custodial charge.
When the custodial charge is considered with the sales charge, the total
deductions are 9.69% and 8.41%, respectively, of the net amount invested.
 
For a subsequent Plan purchase payment of $50, made at a time when that
payment together with the value of SIP Shares then credited totals $5,000 or
less, the sales charge is 9.50% of the net amount invested after deducting the
$1 custodial charge. When the custodial charge is considered with the sales
charge, the total deduction is 11.73% of the net amount invested.
   
See DIFFERENCES UNDER OLD FORM CONTRACTS on page 28 for the determination of
sales charges and other charges under such contracts.     
   
During 1997, Prudential received $43,382 in sales charges and $1,279 in
custodial charges for purchases under the Systematic Investment Plan. The
equivalent figures for 1996 were $30,298 and $1,198, respectively.     
   
These sales and custodial charges may be changed by Prudential subject to
certain conditions. See CHANGING THE CONTRACT, page 28.     
 
LETTER OF INTENT
 
A Letter of Intent form, which should be read carefully, may be completed
under the revised Contracts at any time for "any person" (as defined in the
preceding section) indicating an intention to make SIP Share purchase payments
over a 13-month period for any specific selected amount totaling $10,000 or
more. A Letter of Intent is not binding and creates no obligation on the part
of the Planholder. Under a Letter of Intent, the sales charge rate for each
purchase payment made to fulfill the Letter of Intent is determined as if the
total amount indicated in the Letter of Intent had been paid as a single SIP
Share purchase payment on the first business day of the 13-month period. In
determining the applicable sales charge rate, the value of any SIP Shares
already credited will be considered, as described in the second paragraph
beneath the scale of sales charges in the preceding section.
 
For example, a Planholder submits a Letter of Intent indicating his/her
intention to make SIP Share purchase payments totaling $20,000 over the next
13 months. He/She already has SIP Shares with a net asset value of $10,000.
This means that the sales charge rate for each payment made during the next 13
months to fulfill his/her $20,000 intention will be the rate which would have
applied had the $20,000 been paid as a single payment. Considering $10,000 in
existing SIP Shares, the sales charge rate (as shown in the preceding section)
for a single $20,000 payment is 5% on the first $10,000 and 3% on the next
$10,000, or 4% overall. Thus the sales charge rate for each payment made by
this Planholder under his/her Letter of Intent will be 4%.
   
An initial purchase payment of at least $1,000, or 1% of the intended total
purchase payments, if greater, must accompany submission of a Letter of
Intent. Prudential will restrict the disposition of SIP Shares equal in value
to 1% of the intended total purchase payments until either the intended
purchases have been made or the Letter of Intent has otherwise terminated.
Termination occurs if, before the total intended purchases have been made,
either the 13-month period expires or a liquidation or transfer of SIP Shares
is requested which would require the release of restricted shares. Upon
termination, Prudential will recalculate the sales charge for the purchases
actually made under the Letter of Intent as if they had all been made at one
time on the first business day of the period, and will effect a liquidation of
such number of the restricted SIP Shares as may be required to pay Prudential
for any necessary adjustment in sales charges. Any remaining restricted SIP
Shares will then be released from restriction.     
 
Old Form contracts do not provide for Letter of Intent.
 
OTHER CHARGES
   
A transaction charge is made to cover the expenses of providing the particular
services involved in processing liquidations of SIP Shares. This charge is a
maximum of $1 for each liquidation payment, or 1% of the net amount being
liquidated (after any transfer taxes and any other charges) if less. See
LIQUIDATION (REDEMPTION) OF SIP SHARES, page 9. During 1997 and 1996,
Prudential received $3,036 and $3,028, respectively, in transaction charges.
    
An annual custodial charge is made against each Planholder to cover services
specifically related to the administration of individual Systematic Investment
Plans, other than services involving the receipt of purchase
 
                                      11
<PAGE>
 
   
payments and the liquidation of shares. The charge is $0.95 for each calendar
quarter during which shares are credited under the Systematic Investment Plan.
Prudential will ordinarily deduct the charge from the net investment income
and capital gains distributions allocated to the Planholder for the calendar
year, after deducting any charges for annuity rate protection rights. See the
following two sections and DIFFERENCES UNDER OLD FORM CONTRACTS, page 28. The
annual custodial charge may not exceed the amount of those allocated
distributions after deduction of these other charges. However, in the event of
total liquidation during the year, the charge will be deducted from the
liquidation proceeds. See LIQUIDATION (REDEMPTION) OF SIP SHARES, page 13.
During 1997 and 1996, Prudential received $52,659 and $56,425, respectively,
in annual custodian charges.     
   
An administration charge is applied daily on the value of the net assets in
Prudential's IPA, to cover services in connection with the Account not
specifically related to the administration of individual Plans. The charge is
at an effective annual rate of 3/4 of 1% (0.75%) on the first $250 million of
such assets, 11/20 of 1% (0.55%) on the next $250 million, 3/8 of 1% (0.375%)
on the next $500 million and 9/40 of 1% (0.225%) on any excess over $1
billion. During 1997 and 1996, Prudential received $1,824,694 and $1,684,269,
respectively, in administrative charges.     
   
The annual custodial charge and the administration charge are designed to
reimburse Prudential for the development, administration and modification
costs of the Program allocable to the Plan.     
   
The charges described in this section and under SALES AND RELATED CHARGES on
page 10 are either deducted from purchase or liquidation payments or
distributions under the Plan, or are made against the net assets of
Prudential's IPA. In addition, an investment advisory fee, determined daily at
the rate of 0.125% ( 1/8 of 1%) per year of the average net assets of the
Fund, is paid by the Fund to Prudential. Thus, at present, a total charge
against assets at a yearly rate of about 0.875% ( 7/8 of 1%) is made in
respect to Plans. See PRUDENTIAL'S GIBRALTAR FUND, INC. page 8.     
   
The charges described above may all be changed by Prudential, subject to
certain conditions. See CHANGING THE CONTRACT, page 28.     
 
ANNUITY RATE PROTECTION
   
Annuity rate protection rights must be purchased with respect to each purchase
under the Plan. Each right assures the Planholder that if, at some future
date, he/she should purchase a Variable Annuity under the Program or a
Prudential Fixed-Dollar Annuity outside the Program and elect to use that
right, the schedule of annuity rates in effect at the time the right was
acquired, rather than any higher rate that may then be in effect, will be
applied to $100 of the annuity purchase price (after any premium taxes).
Rights would not be used if an annuity purchase is made at a time when the
schedule of annuity rates assured by the rights is not more favorable than the
rates currently in effect.     
   
Annuity rate protection rights are provided in units of $100. One, three or
five rights may be purchased for each $100 of Systematic Investment Plan
purchase payment, up to the current limit of a total of 1,000 rights
accumulated for a Planholder. A rights charge of $0.25 is made for each $100
Right purchased (equivalent to 0.25% of the purchase price), which will be
deducted from the Planholder's allocated share of the annual net investment
income and capital gains distributions next determined after the Plan purchase
payment for which the right was acquired. See DISTRIBUTIONS on page 13. If the
distribution is insufficient to pay the rights charge, a sufficient number of
SIP Shares credited to the Planholder will be liquidated to pay the
deficiency. Thus, for example, if election is made to purchase 5 rights with
each $100 purchase payment under the Plan and a $250 purchase payment is made,
the Planholder would acquire 12.5 rights, at a cost of $3.13 (12.5 x $0.25,
which is 1.25% of the purchase price), to be deducted from his/her subsequent
distribution, and would be protected against future adverse changes in the
schedule of annuity rates to the extent of $1,250 of annuity purchase price.
    
Annuity rate protection rights may be used only on the life of the Planholder
for whom they were purchased, the co-Planholder, if any, or, at the
Planholder's death, his/her spouse if also a Planholder. Each right shall
terminate (1) one year after the death of the Planholder or after the death of
the survivor of the Planholder and a co-Planholder, if any, or (2) one year
after the last date on which SIP Shares or purchased annuities were in effect
for the Planholder under the Program, whichever is the earlier.
   
If a Planholder exchanges his/her interests in Prudential's IPA for a variable
annuity (whether or not annuity rate protection rights are used), a sales
charge is made upon the exchange. The amount of this charge is 1.50% of the
first $5,000 paid for a variable annuity. The charge is lower for aggregated
payments exceeding $5,000. In addition,     
 
                                      12
<PAGE>
 
   
the Planholder may have to pay a capital gains tax if SIP Shares are
liquidated as part of the exchange. See, for the variable annuity contract,
SALES AND OTHER CHARGES on page 15.     
 
For Plans issued for delivery in Maryland and New York, an additional purchase
of annuity rate protection rights will, under most circumstances, be required
each year out of the Planholder's allocated share of the annual net investment
income and capital gains distributions, to provide for any increases in the
value of the Plan during the year for which rights have not otherwise been
provided, as described in the first two paragraphs of this section. Where
required, one right will be purchased for each $100 of any such increase
during the period from the close of business on the date of determining the
Planholder's allocated share of such distributions in one year to the close of
business on the corresponding date in the next.
   
For differences in the provisions of annuity rate protection and in the method
of paying the rights charge, under Old Form Contracts, see DIFFERENCES UNDER
OLD FORM CONTRACTS, page 28.     
 
DISTRIBUTIONS
   
Prudential will determine each Planholder's allocated share of the annual net
investment income and capital gains distributions, if any, of Prudential's
IPA. From this allocated share will be deducted first, any charge for annuity
rate protection rights, as described above under ANNUITY RATE PROTECTION, and
then the annual custodial charge. The remainder will be applied, at net asset
value without sales charge as of the date of distribution, to increase the
number of SIP Shares credited to the Planholder. The date of distribution will
ordinarily occur once a year in December.     
   
See DIFFERENCES UNDER OLD FORM CONTRACTS on page 28 for a description of
distributions under such Contracts.     
 
LIQUIDATION (REDEMPTION) OF SIP SHARES
   
The Planholder may at any time effect a total liquidation of the SIP Shares
credited under his/her Plan. Prudential will pay the total value of such
shares, determined as of the end of the business day on which the request for
liquidation is received, less any applicable transfer taxes, the transaction
charge, and the annual custodial charge if not already collected. Currently no
transfer taxes are being imposed. The value per share is calculated as
described under PURCHASE PAYMENTS AND THE CREDITING OF SIP SHARES, page 9.
    
Partial liquidations of SIP Shares may be made from time to time. The minimum
partial liquidation is $100 and it must leave a minimum value of $200 for the
shares remaining credited under the Plan after the transaction. Sufficient
shares and fractions of shares will be liquidated to pay the amount requested,
plus the transaction charge and any applicable transfer taxes. If a requested
partial liquidation would result in shares remaining credited under the Plan
with a total value below $200, the request will be treated as if it had been a
request for total liquidation. However, these minimums will not apply, nor
will a transaction charge be required, upon a liquidation of the SIP shares
credited as a result of an annual distribution, if the request for liquidation
is made within 30 days after the date of distribution.
 
When the proceeds of a total or partial liquidation of SIP Shares are used to
provide a variable annuity under the Program, no transaction charge is made.
 
REINVESTMENT OF TOTAL OR PARTIAL LIQUIDATION. With respect to one total or
partial liquidation in each calendar year, the Planholder may reinvest the
amount liquidated without sales charge. A single reinvestment purchase may be
made within twelve months after the date of the liquidation, in an amount not
exceeding the net proceeds of the liquidation reduced by any part of the
liquidation used to purchase an annuity under the Program. Annuity rate
protection rights are not purchased in respect to such reinvestments.
   
SYSTEMATIC LIQUIDATION (PERIODIC WITHDRAWAL). Under this arrangement the
Planholder liquidates each month either a specific number of SIP Shares or the
number of full and fractional shares required to provide a specific cash
amount. For each payment, sufficient shares will be liquidated to provide the
payment requested and to pay the transaction charge and any applicable
transfer taxes. In addition, the annual custodial charge, if not previously
collected, will be deducted from the final payment. A requested systematic
liquidation will be rejected if the first payment under the arrangement
requested would be less than $20. Purchases of SIP Shares during a period of
systematic liquidation would in effect involve duplicate sales charges. For
this reason, Prudential will not ordinarily permit a purchase of less than
$5,000 during a systematic liquidation, and will permit purchases of $5,000 or
more     
 
                                      13
<PAGE>
 
only if the particular purchase transaction is deemed suitable. Since
systematic liquidation payments represent proceeds from the liquidation of SIP
Shares credited to the Planholder, they serve to reduce his/her invested
capital to the extent that they exceed reinvested net investment income and
capital gains distributions.
   
Any requested liquidation payment during a Letter of Intent period is subject
to any prior claim for sales charges Prudential may have to the share
proceeds, as described under LETTER OF INTENT, page 11.     
   
All liquidation payments will be made to the Planholder unless he/she directs
otherwise. Each liquidation payment may result in a gain or loss which the
Planholder would report on his/her income tax return. Each payment will be
made within seven days after the request for liquidation is received, except
as Prudential may be permitted under any valid and applicable law to suspend
the payment.     
   
Suspension is currently permissible only when the NYSE is closed on other than
a regular holiday or weekend or when, as determined by rule or regulation of
the Securities and Exchange Commission, trading thereon is restricted, or an
emergency exists as a result of which disposal of securities held by the Fund
is not reasonably practicable or it is not reasonably practicable for the
value of the Fund's assets to be fairly determined, or when the Securities and
Exchange Commission has provided for such suspension for the protection of
Planholders.     
   
There are certain differences in the liquidation provisions under Old Form
Contracts. See DIFFERENCES UNDER OLD FORM CONTRACTS, page 28.     
 
TRANSFERRING SIP SHARES
 
At the Planholder's request all or a part of the SIP Shares credited under
his/her Plan may be transferred to another person. If only a portion of the
shares are transferred, they must have a net value of at least $100, with
shares having a value of at least $200 remaining credited under the Plan of
the transferring Planholder. Any transferee who is not a Planholder must
become one at the time of transfer, and in this case the net value of the
shares transferred must be at least $300, the purchase minimum for a
Planholder's initial purchase under a Plan.
   
A requested transfer during a Letter of Intent period is subject to any prior
claim Prudential may have to the share proceeds. See LETTER OF INTENT, page
11.     
 
SUBSTITUTION OF FUND SHARES
   
Subject to any applicable law or regulation, Prudential may, in the interest
of Planholders and upon any required approval of the Securities and Exchange
Commission, substitute in Prudential's IPA (either as to Fund shares to be
purchased or as to Fund shares both to be purchased and already purchased)
registered fund shares of a mutual fund with investment objectives similar to
those of the Fund and whose shares are generally of comparable quality to Fund
shares.     
   
Before any such substitution Prudential will give each Planholder 90 days'
written notice of what is planned, including the reasons for the change and a
reasonable description of the shares to be substituted. Each Planholder who
does not then totally liquidate his/her shares before the effective date of
the proposed substitution shall be conclusively deemed to have agreed to the
substitution and to bearing a pro rata share of any expense which it entails.
    
                 DESCRIPTION OF THE VARIABLE ANNUITY CONTRACT
   
The Variable Annuity Contract provides the Planholder with a means of
obtaining a lifetime monthly annuity under which the monthly annuity payments
vary according to the investment results of a portfolio consisting primarily
of common stocks. The Planholder may use either the value of Plan interests or
funds from other sources as the purchase payment. Several types of variable
annuity are available, as described on page 16.     
 
PURCHASING A VARIABLE ANNUITY
   
A person who wishes to purchase a variable annuity, either with the amount
accumulated under a Plan or with funds from other sources, must furnish
Prudential with (1) written instructions in a form satisfactory to Prudential
    
                                      14
<PAGE>
 
   
as to the type of annuity desired, (2) proof satisfactory to Prudential of the
date of birth of the Planholder and, if a last survivor life annuity is
selected, of the contingent annuitant, and (3) sufficient funds to carry out
the instructions for the purchase.     
   
The purchase of the variable annuity is made on the first business day on
which the office of Prudential which services these contracts has all of the
above, at the annuity share value next determined. That day is called the
purchase date. Prudential will send a Planholder's first monthly annuity
payment on the first day of any calendar month chosen, so long as the day
selected is at least one month but no more than 37 months after the purchase
date. The day on which the first monthly annuity payment is due is called the
initial payment date.     
   
The purchase of a variable annuity is subject to Prudential's rules in effect
at the time in respect to age and amount, and to any requirements imposed by
federal or state laws or regulations. Currently the minimum amount that must
be applied to purchase a variable annuity under the Program is $2,000 for the
initial annuity purchased and $1,000 for any subsequent annuity for the same
Planholder. See DIFFERENCES UNDER OLD FORM CONTRACTS, page 28, for minimum
purchase requirements under such Contracts.     
 
SALES AND OTHER CHARGES
 
A sales charge and any applicable premium taxes are deducted from each gross
purchase payment applied to purchase a variable annuity. The sales charge is
expressed as a percentage of the adjusted gross purchase payment, which is the
gross purchase payment reduced by any applicable taxes.
 
The applicable sales charges are as follows. In certain cases, described
below, the sales charges will be lower.

For these sales charges to apply, the proceeds from the Plan liquidation must
be used to purchase a variable annuity within three months after the
liquidation. If a Planholder makes a minimum variable annuity purchase, using
the liquidation proceeds of SIP Shares acquired by a series of minimum
purchases, and if there were no change in the SIP Share Value after the
initial purchase, this sales charge, together with the sales and custodial
charges for the SIP Share purchases and the cost of the annuity rate
protection rights, would total approximately 11.8% of the SIP purchase
payments.     
 
ACCUMULATION OF PURCHASES. For purposes of determining the sales charge,
annuity purchases on the life of the Planholder and his/her spouse and his/her
children under age 21 are combined, and their previous annuity
 
                                      15
<PAGE>
 
   
purchases under the Program, whenever made, are included in determining which
percentage applies. For example, a man and his wife make two $5,000 adjusted
gross purchase payments a few months apart. Neither payment is from Plan
liquidations. The sales charge is 8.50% of the first adjusted gross purchase
payment, and 7.00% of the second such payment. Purchases from Systematic
Investment Plan liquidations are not combined with other purchases for this
purpose because of the lower sales charges which apply to such purchases, as
shown in the table above.     
   
For differences in the determination of sales charges and the accumulation of
purchases under Old Form Contracts, see DIFFERENCES UNDER OLD FORM CONTRACTS
on page 28.     
 
TAXES. The amount and timing of any applicable premium tax varies depending on
the jurisdiction, and is subject to change by the legislature or other
authority. In many jurisdictions there is no tax at all. The current tax rates
for those jurisdictions imposing a tax range from 1% to 5%.
   
OTHER CHARGES. A mortality risk charge, an expense risk charge and an
administrative charge, at effective annual rates of 0.075%, 0.150% and 0.150%,
respectively, for a total of 0.375%, or 3/8 of 1%, per year, are applied daily
on the value of the net assets held for the benefit of the contracts
participating in Prudential's APA.     
   
ACCOUNT. These charges are to cover Prudential's general administrative
expenses in operating the Account and to provide a surplus for use, if
necessary, to help Prudential fulfill its contractual obligations discussed
under the heading THE RISKS WHICH PRUDENTIAL ASSUMES on page 18.     
   
The administrative charge applied against Account assets is designed to
reimburse Prudential for the development, administration and modification
costs of the Program allocable to the Variable Annuity Contract.     
   
During 1997, The Prudential received $0 in sales charges and $8,651 in charges
made against the net assets of the Account. The equivalent figures for 1996
were $0 and $8,734, respectively.     
   
In addition to the above charges, the investment advisory fee described under
PRUDENTIAL'S GIBRALTAR FUND, INC. on page 8, determined daily at the rate of
0.125% (1/8 of 1%) per year of the average net assets of the Fund, is paid by
the Fund to Prudential. Thus, at present, a total charge against assets at a
yearly rate of about 0.50% (1/2 of 1%) is made in respect to variable
annuities.     
   
The charges described above may all be changed by Prudential, subject to
certain conditions. See CHANGING THE CONTRACT, page 28.     
 
RIGHT TO CANCEL
   
You have the right, within ten days after you receive your Contract, to
surrender the Contract by delivering or mailing it, with written notice that
you wish to surrender it, to an office of Prudential or to the agent through
whom the Contract was purchased. Upon such surrender Prudential will cancel
the Contract and pay the owner an amount equal to the sum of (1) the
difference between any purchase payments paid and the amounts allocated to any
separate accounts under the Contract and (2) the net asset value of the
Contract on the date of surrender attributable to the amounts so allocated.
However, if applicable state law so requires, the amount of the purchase
payment will be returned instead.     
 
THE TYPES OF ANNUITY AVAILABLE
 
The following types of variable annuity are described in the Contract.
 
TYPE A -- LIFE ANNUITY. Annuity payments are payable only during the lifetime
of the Planholder. This type provides a larger monthly payment than do Types B
and C, described below, because payments cease when the Planholder dies. For
example, it would be possible under this type for the Planholder to receive
only one annuity payment if death were to occur within the first month after
the first monthly annuity payment. Accordingly, this type is primarily
appropriate where larger income during the Planholder's lifetime is of greater
importance than preservation of a remainder for dependents.
 
TYPE B -- LIFE ANNUITY -- 10 YEARS CERTAIN. Annuity payments are payable
during the lifetime of the Planholder. If the Planholder dies before the 120th
monthly payment is due, monthly annuity payments do not continue to the
beneficiary. Instead, the discounted value of the remaining unpaid
installments, to and including the 120th monthly payment, is payable to the
beneficiary in one sum.
 
 
                                      16
<PAGE>
 
TYPE C -- LAST SURVIVOR LIFE ANNUITY. Annuity payments are payable as long as
either the Planholder or the designated contingent annuitant is living. This
type of annuity has a particular appeal to a husband and wife. As with the
Type A--Life Annuity above, it would be possible under this type of annuity
for only one monthly annuity payment to be made, if both the Planholder and
the contingent annuitant died within the first month after annuity payments
begin.
 
HOW VARIABLE ANNUITY PAYMENTS ARE DETERMINED
   
The amount of the monthly variable annuity payment depends on (1) the net
purchase payment for the annuity, (2) the type of annuity selected, (3) the
date of birth and sex of the Planholder, and of the contingent annuitant under
a Type C Annuity, (4) the annuity rate table selected by Prudential for these
Contracts (see SCHEDULES OF ANNUITY RATES, below), (5) the number of complete
months between the purchase date and the initial payment date, and (6) the
investment results of Prudential's APA, which, in turn, reflect the investment
results of the Fund.     
 
The first five items together provide the basis for determining the dollar
amount of monthly annuity that would be paid if there were no change in the
monthly value of an annuity share. This dollar amount is called the tabular
monthly annuity. It is converted to a monthly number of annuity shares by
dividing that amount by the annuity share value on the purchase date. The
monthly number of annuity shares thus established remains the same through the
duration of the annuity except for the possibility of temporary additional
annuity shares as described in the third paragraph under SCHEDULES OF ANNUITY
RATES, below.
   
The investment results of the Account, item (6), are reflected in changes in
the monthly value of an annuity share (the annuity share value) to the extent
that the rate of net investment return (after deducting the administrative and
risk charges described under SALES AND OTHER CHARGES, page 10) is greater or
less than the effective annual interest rate assumed in the applicable
schedule of annuity rates. The amount payable on the first day of each month
beginning with the initial payment date is the product of (a) the monthly
number of annuity shares and (b) the annuity share value calculated as of one
month and one business day prior to the due date of the payment.     
   
SCHEDULES OF ANNUITY RATES. The schedules currently contained in the variable
annuity contract are based on the Annuity Table for 1949 with adjustments
described in the Contract to reflect improving mortality trends, and with
assumed effective annual interest rates of 3.5% or 5%. The 5% schedule is
applicable in all but a few states in which it is currently not available
under the state law or regulations. In these few states (Florida, New Mexico,
Texas and West Virginia) the 3.5% schedule applies. See DIFFERENCES UNDER OLD
FORM CONTRACTS on page 28 for the additional availability of the 3.5% schedule
under those Contracts.     
   
The 5% schedule, because it is based upon a higher assumed effective annual
interest rate, results in a greater initial monthly annuity payment than is
provided under the 3.5% schedule. However, in reflecting the investment
results of the Fund, the annuity share value for an annuity using the 5%
schedule will increase more slowly and decrease more quickly than will the
annuity share value for an annuity using the 3.5% schedule. As a rough rule of
thumb, the 3.5% schedule should turn out to be more advantageous for
Planholders who live longer than the average, while the 5% schedule should be
better for Planholders for whom the larger early payments are especially
important.     
   
The variable annuity contracts are entitled to participate in the divisible
surplus of Prudential, as may be determined annually at the sole discretion of
Prudential's Board of Directors. The board has determined that Planholders
receiving annuity payments will so participate in 1998. They will be
temporarily credited with an additional number of monthly annuity shares on
which annuity payments in 1998 are based. There is no assurance that such
participation in the divisible surplus of Prudential or temporary crediting of
annuity shares will occur for any future year.     
   
Prudential is currently considering reorganizing itself into a stock company.
This form of reorganization, known as demutualization, is a complex process
that may take a year or more to complete. No plan of demutualization has been
adopted yet by Prudential's Board of Directors. Adoption of a plan of
demutualization would occur only after enactment of appropriate legislation in
New Jersey and would have to be approved by Prudential's policyholders and
appropriate state insurance regulators. Throughout the process, there will be
a continuing evaluation by the Board of Directors and management of Prudential
as to the desirability of demutualization. The Board of Directors, in its
discretion, may choose not to demutualize or to delay demutualization for a
time.     
 
ANNUITY SHARE VALUE. For these Contracts, the annuity share value for July 1,
1969 was set at $1. The annuity share value for any subsequent business day is
determined by multiplying the annuity share change factor for that day (see
below) by the annuity share value for the immediately preceding business day.
   
The annuity share change factor for any business day is obtained by (1) adding
to 1.00 the rate, after provision for any taxes, of net investment income
earned and of asset value changes in Prudential's APA from the end of the     
 
                                      17
<PAGE>
 
   
preceding business day to the end of the current business day, and (2)
deducting from such sum the administrative and risk charges. See the paragraph
headed OTHER CHARGES on page 11. The remainder is then divided by the sum of
1.00 and the rate of interest on a daily basis at the effective annual rate
assumed in the applicable schedule of annuity rates. No provision is currently
made for federal income taxes in determining the change factor. See FEDERAL
INCOME TAXES, page 30.     
   
An alternative gradual investment in Prudential's APA is possible under Old
Form Contracts. See DIFFERENCES UNDER OLD FORM CONTRACTS on page 28.     
   
Shown below are the annuity share values as of the last business day of each
year of the ten year period ending December 31, 1997. Each share value listed
was used to determine annuity payments for the second succeeding month. For
example, the share value as of the last business day in December is used to
compute the February annuity payment. Annuity share values are the same under
these Contracts and the Old Form Contracts.

THE RISKS WHICH PRUDENTIAL ASSUMES     
   
Prudential assumes the risk (1) that annuitants as a class may live longer
than estimated, with the result that payments will continue for longer than
expected, and (2) that charges under the Contracts may not be enough to cover
the actual expenses incurred. In either event, the loss will fall on
Prudential. These risks assumed by Prudential must be evaluated in the light
of Prudential's right, upon 90 days' notice to Planholders, to make certain
changes in the Contracts, including the charges and the schedule of annuity
rates, thereby reducing exposure to loss as a result of the guarantee.
However, such changes would apply only to new purchases after the effective
date of the change and not to any annuities already in effect or annuity rate
protection rights already acquired but not yet exercised. See CHANGING THE
CONTRACT, page 28.     
   
Even though the assets of Prudential's APA are separately accounted for, the
entire general account assets of Prudential are available to meet the expenses
and fulfill Prudential's obligations for the variable annuities purchased
under the variable annuity contracts. The charges Prudential makes for
assuming these risks are described in the subsection headed OTHER CHARGES,
page 11.     
   
On the other hand, the charges may exceed the expenses that Prudential
ultimately incurs under these Contracts. As the actual experience is realized,
the amount by which any such excess is greater than the amount which must
prudently be retained to fulfill Prudential's obligations will become a part
of the divisible surplus of Prudential.     
   
In the event the Fund suspends the redemption of its shares because of the
closing of the NYSE or other emergency reason, Prudential will make annuity
payments during the period of suspension out of its general account assets.
The amount of such payments will be determined in a fair and equitable manner
satisfactory to the Department of Insurance of the State of New Jersey.     
 
CHANGING THE ANNUITY SELECTED
   
Prudential will change the initial payment date of a Planholder's Variable
Annuity under certain conditions. The Planholder must send a request for the
change to Prudential in a form satisfactory to Prudential, which is received
at least seven days before the new initial payment date requested by the
Planholder and at least one month and seven days before the original initial
payment date. Also, the new initial payment date must be one that the
Planholder could have selected in the first place. See PURCHASING A VARIABLE
ANNUITY, page 14.     
 
                                      18
<PAGE>
 
   
Prudential will also change the type of annuity selected to one which the
Planholder could have selected when he/she purchased his/her variable annuity,
again subject to certain conditions. The Planholder must send a request for
the change to Prudential in a form satisfactory to Prudential and, if the
requested change is to a Type C Annuity, there must be proof satisfactory to
Prudential of the date of birth of the contingent annuitant. This request and
information must be received at least one month and seven days before the
initial payment date selected by the Planholder.     
 
CANCELING THE ANNUITY
   
The Planholder may cancel the annuity by making a request in a form
satisfactory to Prudential, if Prudential receives the request no later than
the initial payment date. Prudential will cancel the annuity as of the first
business day not earlier than the day of such receipt and will pay the
Planholder the termination value of the annuity. An annuity may not be
canceled after the initial payment date.     
   
If the Planholder dies before the initial payment date, Prudential will cancel
the annuity on the first business day not earlier than the day on which
Prudential receives due proof of death and claim forms satisfactory to it, and
will pay the termination value to the beneficiary entitled to settlement. See
NAMING A BENEFICIARY, page 27.     
 
The termination value is approximately equal to the net amount which was
required to provide the annuity as of the purchase date (after deduction of
any applicable premium tax and sales charge), increased at the assumed
effective annual interest rate and increased or decreased in accordance with
the rate of change in the annuity share value between the annuity purchase
date and the cancellation date.
   
If a tax was deducted at the time of purchase, there will also be a return of
the lesser of the amount deducted and the amount of tax credit granted by the
state because of cancellation of the annuity. There will also be an adjustment
for any annuity payments that may have been made before notice of death is
received. Payment of this termination value is in full settlement of all
liability of Prudential for the canceled annuity. The termination value will
be paid within seven days after the date of cancellation, except as Prudential
may be permitted under any valid and applicable law to suspend such payment.
Circumstances under which suspension may be permissible are described under
REDEMPTION OF FUND SHARES on page 26.     
   
No amount is payable upon the death of a Planholder after the initial payment
date of an annuity, except for any amount which may be payable under a Type B
Annuity, as described under THE TYPES OF ANNUITY AVAILABLE on page 16. Of
course, upon the death of either the Planholder or the designated contingent
annuitant under a Type C Annuity (described on page 17) monthly payments will
continue in accordance with the provisions of the annuity for the remaining
lifetime of the survivor.     
 
THE CONTINUING RIGHT TO PURCHASE AN ANNUITY
   
Prudential will continue to provide annuities in the following situations.
First, Planholders who have acquired annuity rate protection rights may
exercise those Rights in accordance with their terms. Second, Planholders with
shares credited under the Plan or the Program will be able to exchange them at
any time for variable annuities. Also see DIFFERENCES UNDER OLD FORM CONTRACTS
on page 28.     
 
               DESCRIPTION OF PRUDENTIAL'S GIBRALTAR FUND, INC.
 
INVESTMENT POLICIES
 
The Fund invests primarily in common stocks and other securities convertible
into common stocks. Notwithstanding its growth objective, the Fund may invest
a relatively small percentage of assets, which Fund management interprets to
be not more than 15%, in preferred stocks, bonds, debentures, notes and other
evidences of indebtedness, of a character customarily acquired by
institutional investors, whether or not publicly distributed. These may or may
not be convertible into stock or accompanied by warrants or rights to acquire
stock.
 
At times, when economic conditions or general levels of common stock prices
are such that it may be deemed temporarily advisable to curtail investments in
common stocks, a larger than usual proportion of the Fund's assets may be
invested in such preferred stocks and evidences of indebtedness, or may be
held in cash or its equivalents,
 
                                      19
<PAGE>
 
   
as a defensive measure. Nevertheless, not more than 10% of the assets of the
Fund may be invested in loans made through the purchase of privately placed
evidences of indebtedness of a character customarily acquired by institutional
investors. See the subheading SPECIAL RISKS, page 21.     
 
In addition, the Fund may hold at times a moderate amount of cash and high-
grade, short-term debt securities to facilitate the orderly and flexible
programming of investments. Such debt securities may include securities
acquired through short-term repurchase transactions which will be "fully
collateralized," I.E., the value of the securities held by the Fund will be at
least equal to the repurchase price, including accrued interest.
   
Normally the Fund will hold securities purchased for more than one year,
although it will sell individual securities when their current price seems
clearly excessive in relation to estimated present or future value or when the
situation of the issuer appears to be deteriorating. The Fund's portfolio
turnover is discussed under the heading PRUDENTIAL AS MANAGER OF THE FUND'S
INVESTMENTS on page 23. The Fund does not plan to trade for short-term
profits, but may take advantage of occasional opportunities for such profits
if circumstances make this advisable. To the extent that the Fund makes short-
term investments, it would incur greater brokerage charges than would
otherwise be the case, and any short-term capital gains would constitute
ordinary income.     
 
RESTRICTIONS ON INVESTMENT
   
The Fund operates under a number of investment restrictions. Some arise out of
state laws and are summarized under NEW JERSEY INVESTMENT LAWS on page 21.
Those which follow, as well as the investment policies described above, are
self-imposed, fundamental policies of the Fund. They may not be changed
without the vote of a majority of the Fund's outstanding voting securities.
    
The Fund does not:
   
(1) underwrite the securities of other issuers, except where it may be deemed
    to be an "underwriter" for purposes of the Securities Act of 1933, as
    amended, as indicated under SPECIAL RISKS below;     
 
(2) buy or sell commodities or commodity contracts;
 
(3) sell short or buy on margin, or buy, sell or write put or call options or
    combinations of such options;
 
(4) invest for the purpose of exercising control or management;
 
(5) buy or hold the securities of any issuer if those officers and directors
    of the Fund or officers of its investment advisor who own individually
    more than one-half of 1% of the securities of such issuer or together own
    more than 5% of the securities of such issuer;
 
(6) with respect to 75% of the value of its assets, buy the securities of an
    issuer if the purchase would cause more than 5% of the value of the Fund's
    total assets to be invested in the securities of any one issuer (except
    for obligations of the United States government and its instrumentalities)
    or result in the Fund owning more than 10% of the voting securities of
    such issuer;
 
(7) concentrate its investments in any one industry (no more than 25% of the
    value of the Fund's assets will be invested in any one industry);
 
(8) borrow money;
 
(9) buy or sell real estate, although the Fund may purchase shares of a real
    estate investment trust;
 
(10)  invest in the securities of other investment companies; or
 
(11) issue senior securities.
   
SECURITIES LENDING. The Fund may from time to time lend its portfolio
securities to broker-dealers, qualified banks and certain institutional
investors, provided that such loans are made pursuant to written agreements
and are continuously secured by collateral in the form of cash, U.S.
government securities or irrevocable standby letters of credit in an amount
equal to at least the market value at all times of the loaned securities.
During the time portfolio securities are on loan, the lender continues to
receive the interest and dividends, or amounts equivalent thereto, on the
loaned securities while receiving a fee from the borrower or earned interest
on the investment of the cash collateral. The right to terminate the loan is
given to either party subject to appropriate notice. Upon termination of the
loan, the borrower returns to the lender securities identical to the loaned
securities. Prudential has advised the Fund's Directors that the lender does
not have the right to vote securities on loan, but Prudential would terminate
the loan and cause the loaned securities to be returned to the Fund in order
to exercise the voting rights if that were considered important with respect
to the investment. The primary risk in lending securities is that the     
 
                                      20
<PAGE>
 
borrower may become insolvent on a day on which the loaned security is rapidly
advancing in price. In such event, if the borrower fails to return the loaned
securities, the existing collateral might be insufficient to purchase back the
full amount of stock loaned, and the borrower would be unable to furnish
additional collateral. The borrower would be liable for any shortage; but the
Fund would be an unsecured creditor to such shortage and might not be able to
recover all or any of it. However, this risk may be minimized by a careful
selection of borrowers and securities to be lent.
   
The Fund will not lend its portfolio securities to entities affiliated with
Prudential, including Prudential Securities Incorporated. This will not affect
the Fund's ability to maximize its securities lending opportunities.     
   
AMERICAN DEPOSITARY RECEIPTS. The Fund may also invest in American Depository
Receipts (ADRs) which are U.S. dollar-denominated certificates issued by a
United States bank or trust company and represent the right to receive
securities of a foreign issuer deposited in a domestic bank or foreign branch
of a United States bank and traded on a United States exchange or in an over-
the-counter market.     
   
SPECIAL RISKS. In addition to the previously mentioned restrictions, the Fund
may invest no more than 10% of the value of its assets in securities which,
because of legal or contractual restrictions upon resale or for other reasons,
are not readily marketable. Such securities include the privately placed
evidences of indebtedness referred to above. As of December 31, 1997, such
restricted securities comprised approximately 1% of the Fund's net assets.
       
Any investment in such securities may entail special risks because of
difficulties in selling them. If the securities were to be sold publicly, the
Fund may be deemed an "underwriter" for purposes of the Securities Act of
1933, as amended, and may be required to register the securities under that
Act. In that case, the Fund might have to bear the expense of such
registration, and the delays in the sale pending the registration could result
in a lower selling price.     
 
If the securities were to be sold privately, the price obtainable might be
lower than would be obtained if the securities could be publicly marketed.
 
The value of any such securities will be determined in good faith by or under
the authority of the Fund's Board of Directors. A determination that the value
of particular securities is less than would have been the case had the
securities been freely marketable will make the net asset value of Fund shares
correspondingly lower.
 
Investment in ADRs has certain advantages over direct investment in the
underlying foreign securities because they are easily transferable, have
readily available market quotations and the foreign issuers are usually
subject to comparable auditing, accounting and financial reporting standards
as domestic issuers. Nevertheless, as foreign securities, ADRs involve certain
risks which should be considered fully by investors. These risks include
political or economic instability in the country of the issuer, the difficulty
of predicting international trade patterns, and the fact that there may be
less publicly available information about a foreign company than about a
domestic company.
 
Investment by the Fund in warrants or rights to acquire stock may also entail
risks. The Fund will not purchase any such warrants or rights if after giving
effect to such purchase the total cost to the Fund of all warrants and rights
then held by it will exceed 3% of the value of its assets. Warrants are
basically options to purchase securities at a specified price within a given
time. They are highly speculative, have no voting rights, pay no dividends,
and have no rights with respect to the assets of the corporation that issues
them. The price of warrants does not necessarily move parallel with the price
of the underlying securities.
 
NEW JERSEY INVESTMENT LAWS
   
As long as Prudential, or a subsidiary or affiliate thereof, continues to be
the investment advisor of the Fund, the Fund's investments must meet
requirements set forth in the Revised Statutes of New Jersey. The Fund has, to
the extent required by law, adopted such requirements as part of its
investment policy while Prudential, or a subsidiary or affiliate, continues as
the investment advisor.     
 
The following is a summary of provisions of current New Jersey law which
impose additional limitations on the investment policies of the Fund described
in the preceding two sections.
 
1. Evidences of indebtedness of a corporation, joint stock association,
   business trust, business joint venture or business partnership may not be
   purchased if in default as to interest.
 
2. The stock of a corporation may not be purchased unless (i) the corporation
   has paid a cash dividend on the class of stock during each of the past five
   years preceding the time of purchase, or (ii) during the five-year period
   the corporation had aggregate earnings available for dividends on such
   class of stock sufficient to pay
 
                                      21
<PAGE>
 
  average dividends of 4% per annum computed upon the par value of such
  stock, or upon stated value if the stock has no par value. This limitation
  does not apply to any class of stock which is preferred as to dividends
  over a class of stock whose purchase is not prohibited.
 
3. Any common stock purchased must be (i) listed or admitted to trading on a
   securities exchange in the United States or Canada; or (ii) included in the
   National Association of Securities Dealers' national price listings of
   "over-the-counter" securities; or (iii) determined by the Commissioner of
   Insurance of New Jersey to be publicly held and traded and as to which
   market quotations are available.
 
4. Additional securities of a corporation may not be purchased if after the
   purchase more than 10% of the market value of the assets of the Fund would
   be invested in the securities of such corporation.
 
These currently applicable requirements of New Jersey law impose substantial
limitations on the ability of the Fund to invest in the stock of companies
whose securities are not publicly traded or who have not recorded a five-year
history of dividend payments or earnings sufficient to support such payments.
This means that the Fund will not generally invest in the stock of newly
organized corporations. Nonetheless, an investment not otherwise eligible
under items 1 and 2 of this section may be made if, after giving effect to the
investment, the total cost of all such non-eligible investments does not
exceed 5% of the aggregate market value of the assets of the Fund.
   
Investment limitations may also arise under the insurance laws and regulations
of other states where contracts of the Program are sold. Although compliance
with the requirements of New Jersey law set forth above will ordinarily result
in compliance with any applicable laws of other states, under some
circumstances the laws of other states could impose additional restrictions on
the portfolio of the Fund.     
 
SUMMARY OF INVESTMENT ADVISORY CONTRACT
   
Under an Investment Advisory Contract, Prudential has agreed to furnish
investment management to the Fund. Such investment management entails the
selection of securities for purchase or sale by the Fund and the resulting
placement of orders. Periodic reports of such purchases and sales are
submitted to the Fund for review by the Board of Directors.     
   
Subject to Prudential's supervision, substantially all of the investment
management services provided by Prudential are furnished by its wholly-owned
subsidiary, PIC, pursuant to the Service Agreement between Prudential and PIC
which provides that Prudential will reimburse PIC for its costs and expenses.
PIC is registered as an investment advisor under the Investment Advisers Act
of 1940, as amended.     
   
Prudential bears the expenses for investment advisory services incurred in
connection with the purchase and sale of securities (but not the brokers'
commissions and transfer taxes and other charges and fees attributable to
investment transactions), the salaries and expenses of all officers and
employees reasonably necessary for the Fund's operations (excluding members of
the Fund's Board of Directors who are not officers or employees of
Prudential), and the office facilities of the Fund. The amount paid to
Prudential for its investment advisory services to the Fund is shown under the
heading PRUDENTIAL'S GIBRALTAR FUND, INC. on page 8.     
 
The Investment Advisory Contract and the Service Agreement will continue in
effect from year to year provided renewal is approved at least annually by the
Fund's Board of Directors, including approval by a majority of those directors
who are not interested persons of either party to the Contract or Agreement.
   
The Investment Advisory Contract also grants the Fund a royalty-free, non-
exclusive license to use the words "Prudential's Gibraltar" and the registered
service mark of a rock representing the Rock of Gibraltar which appears on the
cover of this Prospectus. However, Prudential may terminate this license if
Prudential or a company controlled by it ceases to be the Fund's investment
advisor. Prudential may also terminate the license for any other reason upon
60 days' written notice; but, in this event, the Contract shall also terminate
120 days following receipt by the Fund of such notice, unless a majority of
the outstanding voting securities of the Fund vote to continue the Contract
notwithstanding termination of the license.     
   
The Investment Advisory Contract may be terminated by the Board of Directors
or by the vote of a majority of the Fund's outstanding voting securities on 60
days' notice to Prudential. Prudential may terminate the Investment Advisory
Contract on 90 days' notice to the Fund. The Investment Advisory Contract will
also terminate automatically in the event of its assignment.     
 
 
                                      22
<PAGE>
 
   
Prudential will continue to have responsibility for all investment advisory
services under its advisory or subadvisory agreements with respect to its
clients.     
   
The Investment Advisory Contract with Prudential was approved at the annual
meeting of stockholders held on May 21, 1970. The Board of Directors has
unanimously approved continuance of the Contract in each year since then, most
recently at a meeting held on May 19, 1997.     
   
The Service Agreement between Prudential and PIC will continue in effect as to
the Fund for a period of more than two years from its execution, only so long
as such continuance is specifically approved at least annually in the same
manner as the Investment Advisory Contract between Prudential and the Fund.
The Agreement may be terminated by either party upon not less than 30 days'
prior written notice to the other party, will terminate automatically in the
event of its assignment and will terminate automatically as to the Fund in the
event of the assignment or termination of the Investment Advisory Contract
between Prudential and the Fund. Prudential is not relieved of its
responsibility for all investment advisory services under the Investment
Advisory Contract between Prudential and the Fund. The Agreement provides for
Prudential to reimburse PIC for its costs and expenses incurred in furnishing
investment advisory services.     
   
The Service Agreement between Prudential and PIC was ratified by stockholders
at their annual meeting held on September 27, 1985. The Board of Directors has
unanimously approved continuance of the Agreement in each year since then,
most recently at a meeting held on May 19, 1997.     
   
A separate contract between Prudential and the Fund provides that, as long as
the Fund sells its shares only to Prudential, its separate accounts or
organizations approved by it, Prudential will pay all expenses of the Fund not
covered by the Investment Advisory Contract (except for the fees and expenses
of members of the Fund's Board of Directors who are not officers or employees
of Prudential, brokers' commissions, transfer taxes and other charges and fees
attributable to investment transactions, and any other local, state or federal
taxes). Prudential has accordingly paid the organizational expenses of the
Fund and such other expenses as those incurred in connection with the
registration of the Fund and Fund shares with the Securities and Exchange
Commission, the cost of preparing and printing Fund prospectuses, and fees for
auditors and lawyers. Under the present contractual arrangements, it will
continue to pay any such expenses incurred in the future.     
   
PRUDENTIAL AS MANAGER OF THE FUND'S INVESTMENTS     
   
Prudential Mutual Fund Investment Management (PMFIM), a part of Prudential
Investments and a division of PIC, supplies the services with respect to
equity securities. PMFIM analyzes industries and companies within these
industries in order to recommend purchases and sales of equity securities.
PMFIM is responsible for the management of approximately $85 billion of
publicly-traded U.S. and global equity and fixed income securities. These
assets represent Prudential's mutual fund and annuity accounts, as well as
institutional clients and Prudential's general account and subsidiaries.     
   
Jeffrey Rose, Vice President, PIC, has been portfolio manager for the Fund
since March 1998. Mr. Rose also co-manages the Prudential Balanced Fund.     
   
PMFIM's investment staff selects companies and diversifies investments over
many firms and industries. It provides continuous supervision and management
over the performance of the investments. This is to reduce the risk of
developments which may adversely affect the market value of the securities of
one company or industry. But the emphasis is on the careful choice of
investments believed to have potential for growth, rather than upon
diversification alone.     
 
In implementing the Fund's investment objectives, each securities analyst is
assigned the responsibility of keeping abreast of developments in specific
industries and companies within those industries. On the basis of periodic
contacts with company managements, consultants and research staffs of
investment banking and brokerage firms, as well as analyses of company
reports, business periodicals and standard statistical services, each analyst
makes projections of earnings and dividends, and determines the relative
attraction of the companies he/she follows based on these projections in the
light of current conditions and market price. Securities will be purchased for
the Fund's portfolio and sold from it on the basis of these analyses.
 
                                      23
<PAGE>
 
These methods of selection and supervision, like diversification, while they
do not guarantee successful investment or eliminate the risks involved
therein, are ones which the average individual may not have the time,
facilities, training or funds to employ on his/her own.
   
PORTFOLIO TURNOVER. The Fund's portfolio turnover rates for the last ten years
are shown in the table on page 6. (This rate is used to measure the activity
of a fund's portfolio securities. It is calculated by dividing purchases or
sales, whichever is less, by the average monthly value of the portfolio
securities, in each case excluding securities with maturities of one year or
less.)     
   
As noted elsewhere in this Prospectus, the Fund seeks long-term growth of
capital rather than short-term trading profits. However, during any period
when changing economic or market conditions are anticipated, successful
management requires an aggressive response to such changes, which may increase
the rate of portfolio turnover. The rate of portfolio activity will usually
affect the brokerage costs of the Fund. It is anticipated that under normal
circumstances the portfolio turnover rate would not exceed 100%. During 1997
and 1996 the portfolio turnover rates were 101% and 97%, respectively.     
   
Prudential manages several other securities portfolios, including the
portfolios of The Prudential Series Fund, Inc., The Prudential Variable
Contract Account-2, The Prudential Variable Contract Account-10 and The
Prudential Variable Contract Account-11, registered under the 1940 Act as
open-end management investment companies. Some of these portfolios invest in
common stock. Investment opportunities may become available from time to time
that are suitable both for the Fund and for these other common stock
portfolios. On these occasions, an allocation of the securities available will
be made, taking into account the suitability of the security in the light of
the investment objectives of each portfolio, the size and composition of the
respective portfolios and the availability of cash.     
 
BROKERAGE
   
Prudential is responsible for decisions to buy and sell securities for the
Fund, the selection of brokers and dealers to effect the transactions and the
negotiation of brokerage commissions, if any. Transactions on a stock exchange
in equity securities will be executed primarily through brokers that will
receive a commission paid by the Fund. Fixed income securities, on the other
hand, as well as equity securities traded in the over-the-counter market, will
not normally incur any brokerage commissions. These securities are generally
traded on a "net" basis with dealers acting as principals for their own
accounts without a stated commission, although the price of the security
usually includes a profit to the dealer. In underwritten offerings, securities
are purchased at a fixed price that includes an amount of compensation to the
underwriter, generally referred to as the underwriter's concession or
discount. Certain of these securities may also be purchased directly from an
issuer, in which case neither commissions nor discounts are paid.     
 
In placing orders for securities transactions, primary consideration is given
to obtaining the most favorable price and efficient execution. An attempt is
made to effect each transaction at a price and commission, if any, that
provides the most favorable total cost or proceeds reasonably attainable in
the circumstances. However, a higher commission than would otherwise be
necessary for a particular transaction may be paid if to do so appears to
further the goal of obtaining the best available execution.
   
In connection with any securities transaction that involves a commission
payment, the commission is negotiated with the broker on the basis of the
quality and quantity of execution services that the broker provides, in light
of generally prevailing commission rates. Periodically, Prudential and PIC
review the allocation among brokers of orders for equity securities and the
commissions that were paid.     
   
When selecting a broker or dealer in connection with a transaction for any
portfolio, consideration is given to whether the broker or dealer has
furnished Prudential or PIC with certain services, provided this does not
jeopardize the objective of obtaining the best price and execution. These
services, which include statistical and economic data and research reports on
particular companies and industries, are services that brokerage houses
customarily provide to institutional investors. Prudential or PIC use these
services in connection with all investment activities, and some of the data or
services obtained in connection with the execution of transactions for the
Fund may be used in connection with the execution of transactions for other
investment accounts.     
 
Conversely, brokers and dealers furnishing such services may be selected for
the execution of transactions of such other accounts, while the data or
service may be used in providing investment management for the Fund. Although
 
                                      24
<PAGE>
 
   
Prudential's present policy is not to permit higher commissions to be paid on
transactions in order to secure research and statistical services from
brokers, Prudential might in the future authorize the payment of higher
commissions, but only with the prior concurrence of the Board of Directors of
the Fund, if it is determined that the higher commissions are necessary in
order to secure desired research and are reasonable in relation to all of the
services that the broker provides.     
   
When investment opportunities arise that may be appropriate for more than one
entity for which Prudential serves as investment manager or advisor, one
entity will not be favored over another and allocation of investments among
them will be made in an impartial manner believed to be equitable to each
entity involved. The allocations will be based on each entity's investment
objectives and its current cash and investment positions. Because the various
entities for which Prudential acts as investment manager or advisor have
different investment objectives and positions, from time to time a particular
security may be purchased for one or more such entities while at the same time
such securities may be sold for another.     
   
Prudential Securities Incorporated (Prudential Securities) may act as a
securities broker for the Fund. In order for Prudential Securities to effect
any portfolio transactions for the Fund, the commissions, fees or other
remuneration received by Prudential Securities must be reasonable and fair
compared to the commissions, fees or other remuneration paid to other brokers
in connection with comparable transactions involving similar securities being
purchased or sold on an exchange during a comparable period of time. This
standard would allow Prudential Securities to receive no more than the
remuneration that would be expected to be received by an unaffiliated broker
in a commensurate arm's-length transaction. The Fund may not engage in any
transactions in which Prudential or its affiliates, including Prudential
Securities, acts as principal, including over-the-counter purchases and
negotiated trades in which such a party acts as a principal.     
   
Prudential or its affiliates, including PIC, may enter into business
transactions with brokers or dealers for purposes other than the execution of
portfolio securities transactions for accounts Prudential manages. These other
transactions will not affect the selection of brokers or dealers in connection
with portfolio transactions for the Fund.     
   
During the calendar year 1997, $329,585 was paid to various brokers in
connection with securities transactions for the Fund. Of this amount,
approximately 91.0% was allocated to brokers who provided research and
statistical services to Prudential. The equivalent figures for 1996 were
$662,074 and 64.9%, respectively, and for 1995 were $756,838 and 77.52%,
respectively.     
   
Of the total brokerage fees paid by the Fund during 1997, $24,750 or 7.5% was
paid to Prudential Securities. For 1997, Prudential Securities effected 5.1%
of the transactions involving the payment of commissions, on an aggregate
dollar basis. During 1996, $19,301 or 2.9% was paid to Prudential Securities
which effected 2.2% of the transactions involving the payment of commissions
on an aggregate dollar basis. For 1995, no money or percentage was paid.     
 
DETERMINATION OF NET ASSET VALUE
   
Shares of the Fund are sold to Prudential's IPA, Prudential's APA and
Prudential's Annuity Plan Account-2, which invest the money paid for purchases
under the tax-qualified and non-tax-qualified contracts of the Program. Sales
of Fund shares are made at the net asset value next determined after such
purchases are made.     
   
Prudential determines the net asset value of Fund shares on each business day
(a day on which the NYSE is open for business). The net asset value is
computed by dividing the net assets by the number of outstanding shares of the
Fund. Net assets are the total of cash and other assets, including investment
securities taken at value, minus liabilities.     
   
NASDAQ National Market System equity securities and securities for which the
primary market is an exchange are generally valued at the last sale price on
such system or exchange on that day or, in the absence of recorded sales, at
the mean between the most recently quoted bid and asked prices on that day or
the bid price on such day in the absence of an asked price. Other over-the-
counter equity securities are valued by an independent pricing agent or
principal market maker. Debt obligations with maturities of less than 60 days
are valued at amortized cost. Portfolio securities or assets for which market
quotations are not readily available will be valued at fair value as
determined in good faith by or under authority of the Fund's Board of
Directors.     
 
                                      25
<PAGE>
 
REDEMPTION OF FUND SHARES
   
Redemptions of Fund shares result from liquidations of interests under the
Contracts of the Program, and are made at the net asset value next determined
after such liquidations are made. Payment for shares redeemed will ordinarily
be made within seven days after the redemption request is received from
Prudential.     
   
This right of redemption may, however, be suspended for any period during
which the NYSE is closed on other than a regular holiday or weekend, or
trading thereon is restricted, or for any period during which an emergency
exists as a result of which it is not reasonably practicable for the Fund
either to dispose of securities owned by it or to determine the value of its
assets fairly. Redemption may also be suspended in the event the Securities
and Exchange Commission has provided for such suspension for the protection of
security holders.     
 
DESCRIPTION OF FUND SHARES AND VOTING RIGHTS
 
The Fund's authorized capital is 75,000,000 shares of common stock, $1 par
value. Common stock is purchased with amounts arising from payments made by
participants in the separate accounts of the Prudential Financial Security
Program. All shares of Fund stock are entitled to participate equally in
dividends and distributions of the Fund and in its net assets remaining upon
liquidation after satisfaction of outstanding liabilities. Fund shares are
fully paid and nonassessable when issued and have no preemptive, conversion or
exchange rights. Such shares are redeemable upon request, except under the
circumstances described in the preceding section, REDEMPTION OF FUND SHARES.
   
After a distribution of investment income and realized net capital gains in
December of each year, the balance of the Fund's investment income and
realized net capital gains for the calendar year then ending are normally
distributed during the first calendar quarter after the end of that calendar
year. Any such distributions to the accounts will ordinarily be credited in
the form of additional Fund shares at net asset value. However, partial
distributions may be made in cash to meet expenses of the accounts. See
FEDERAL INCOME TAXES, page 30.     
   
Each share of common stock outstanding is entitled to one vote. Fund shares
are held only by separate accounts of Prudential. At December 31, 1997,
Prudential's IPA and Prudential's APA, the two accounts discussed in this
Prospectus, held, respectively, approximately 81.0% and 1.0% of all Fund
shares outstanding. Prudential's Annuity Plan Account-2, a separate account of
Prudential which is not discussed in this Prospectus, held approximately
18.0%. Fund shares are voted by Prudential in accordance with voting
instructions received from participants in those accounts. Planholders under a
Plan and Planholders (or contingent annuitants or beneficiaries in cases where
a Planholder is deceased) under a Variable Annuity Contract will be notified
of any meeting at which Fund shares may be voted. Planholders in each Account
will be given an opportunity to vote a number of Fund shares proportionate to
their interest in that Account by providing voting instructions on forms
furnished for this purpose by Prudential. If there are Fund shares held in
either Account for which voting instructions are not received, Prudential will
vote those shares on each matter in the same proportion as it votes the Fund
shares held in the account for which it received instructions.     
 
CUSTODIAN, TRANSFER AGENT AND DIVIDEND-PAYING AGENT
   
Investors Fiduciary Trust Company (IFTC), 127 West 10th Street, Kansas City,
Missouri 64105-1716, is the custodian of the Fund's assets and transfer agent
and dividend-paying agent of the Fund. The Fund's custodian maintains certain
financial and accounting books and records on behalf of the Fund pursuant to
an agreement with the Fund.     
 
                           SUPPLEMENTARY INFORMATION
 
CUSTODIAN FOR PRUDENTIAL'S INVESTMENT PLAN ACCOUNT
   
IFTC is custodian for Prudential's Investment Plan Account. IFTC is a trust
company organized under the laws of the State of Missouri. It is subject to
examination by the Missouri Division of Finance and by the Federal Reserve
Board.     
 
                                      26
<PAGE>
 
   
The custodian maintains custody of Fund shares and any other assets of the
Account and is responsible for any loss. However, the custodian will be
relieved of such responsibility to the extent that a loss was occasioned by
other than the negligence of, or robbery, burglary or theft by, its employees.
The custodian will not be liable for acting upon oral instructions from
Prudential with respect to the Account prior to written confirmation, except
in the case of the negligence or willful misconduct of the custodian and/or
its employees. The custodian will not be liable for action taken in good faith
upon any certificate from Prudential which the custodian in good faith
believes to have been validly executed. Neither Prudential, the custodian nor
any other person may create a lien on the Account assets.     
   
In order to reduce the number of times when Fund shares must be redeemed to
meet daily liquidation requests by Planholders, Prudential is required under
the provisions of the custodian agreement to purchase shares of the Account on
days when liquidations by Planholders exceed their purchases and to liquidate
those shares on days when purchases by Planholders exceed their liquidations.
Prudential may also liquidate shares thus credited to it when it believes its
holdings to be too large. Prudential may realize profit or loss whenever it
liquidates shares, depending upon changes in the value of the shares since
Prudential purchased them.     
   
Fund shares related to shares of the Account credited to Prudential will not
be voted.     
   
Either party may terminate the custodian agreement between Prudential and the
custodian after giving 30 days' written notice of termination.     
 
NAMING A BENEFICIARY
   
Subject to Prudential's approval, a beneficiary may be designated (1) for the
shares credited under a Plan, (2) for the termination value of an annuity if
the Planholder dies on or after the purchase date but before the initial
payment date, and (3) if a Type B Annuity is effected, for the discounted
value of the unpaid installments if the Planholder dies after the first but
before the 120th monthly installment is payable.     
   
Prudential reserves the right, prior to making payment in accordance with a
beneficiary designation, to require due proof of the Planholder's death and
such completed claim forms and other evidence as may be required to properly
establish the claim.     
   
Subject to the above, at the death of a Planholder who has SIP Shares
credited, the designated beneficiary, if a natural person taking in his/her
own right, will be credited with that number of the Planholder's SIP Shares
which represent the beneficiary's interest. If such beneficiary is not already
a Planholder, Prudential will establish a Plan for the beneficiary and
transfer the shares so credited to that Plan. However, under the revised Plan
described throughout this Prospectus, if the beneficiary is not a natural
person taking in his/her own right, Prudential will, as of the date of receipt
by Prudential of the required documents, liquidate such number of the deceased
Planholder's SIP Shares as represent that beneficiary's interest and will pay
the proceeds of the liquidation to that beneficiary. See DIFFERENCES UNDER OLD
FORM CONTRACTS below.     
   
For determination of the amount payable, if any, to the beneficiary upon the
death of a Planholder after the purchase date of a variable annuity, see
CANCELING THE ANNUITY on page 19.     
 
ASSIGNMENT
   
The Planholder's interest under his/her Systematic Investment Plan is
assignable only as collateral to a bank or other financial institution and
then only to the extent of the number of SIP Shares credited to the Planholder
on the date of the assignment, exclusive of any subsequent distribution, and
exclusive of any of the Planholder's SIP Shares restricted under a Letter of
Intent. An assignee's only right shall be to liquidate such assigned shares.
Prudential shall not be considered to have knowledge of any assignment unless
the original or a duplicate of the document evidencing the assignment is filed
with Prudential. Prudential assumes no responsibility for the validity or
sufficiency of any assignment, furnishes no forms for that purpose, and
recommends that if an assignment is contemplated, it be prepared with the
advice of the Planholder's legal counsel. Annuity rate protection rights are
not assignable. However, as described under ANNUITY RATE PROTECTION on page
12, such rights may, under certain conditions, be used by a co-Planholder, if
any, or by the Planholder's spouse after the Planholder's death.     
   
Neither the Variable Annuity Contracts nor any values or payments thereunder
are assignable except to Prudential.     
 
                                      27
<PAGE>
 
CHANGING THE CONTRACT
   
Prudential may not change the Contract with respect to any annuity already
purchased. Neither may it change the schedules of annuity rates applicable to
annuity rate protection rights already purchased but not yet exercised.
Otherwise, upon 90 days' notice to Planholders, Prudential may change the
terms and provisions concerning the schedules of annuity rates, annuity rate
protection, the charges by Prudential and the applicable minimum requirements.
Prudential may also refuse to accept any request for a purchase under the
Plan, and it may add or substitute contracts under the Program, provided,
however, that unless the change is required by law or regulation, it will not
affect purchases already made unless the Planholder accepts the substituted
contracts as applying to any such purchases. Also see DIFFERENCES UNDER OLD
FORM CONTRACTS which follows.     
 
Except as provided above, or as required by federal or state law or
regulation, no changes which would adversely affect rights acquired by
Planholders will be made without consent.
 
DIFFERENCES UNDER OLD FORM CONTRACTS
   
As stated in the introductory summary on page 2, the Plan and Variable Annuity
Contracts described in the preceding sections of this Prospectus are the
revised Contracts first offered to the public on September 17, 1973.     
 
Old Form Contracts may continue to be held by some persons who became
Planholders before introduction of the revised Contracts in their state, and
by persons who are added as Planholders pursuant to provisions of outstanding
Old Form Contracts. All such persons will, of course, be governed by the
provisions of their Old Form Contracts. Old Form Contracts can be identified
by the letter A appearing as the 7th digit (and only letter) in the plan
number. Revised Contracts contain the letter B in that spot.
 
CHANGE TO REVISED CONTRACTS. Planholders with Old Form Contracts may, in most
cases, exchange their interests in such Contracts without charge for interests
in the revised Contracts. However, for purchasers of annuities under the
Program prior to introduction of the revised Contracts in their state, the Old
Form Contracts provisions under which such annuities were effected will
continue to govern for those annuities, even if the Contracts are otherwise
exchanged for revised Contracts.
 
The Old Form Contracts are similar in many respects to the revised Contracts.
Therefore, unless otherwise indicated in the preceding sections of this
Prospectus, the information given is equally applicable to the Old Form
Contracts and to interests held under them. There are, however, several
important differences, as well as some lesser ones, as described below.
   
CONTRACTS COMPRISING THE PROGRAM. In addition to the Plan and Variable Annuity
Contracts, the Old Form Contracts for the Planholder include a Fixed-Dollar
Annuity and Annuity Rate Protection Contract.     
 
TRANSFER ACCOUNT. Participation in the Program under Old Form Contracts
requires that a Transfer Account must have been established. The person who
has established and who maintains a Transfer Account is called an
Accountholder. Purchase payments under Old Form Contracts may be made only by
transferring funds from a Transfer Account. For an Accountholder the Transfer
Account Agreement is one of the contracts that make up his/her Program, and
Accountholders are referred to the Agreement for a full statement of its
provisions. Summarized below are those provisions which relate directly to
purchases made from the Transfer Account.
 
An Accountholder may authorize or make purchases from his/her Transfer Account
for any family member (the Accountholder, his/her spouse, their parents,
children, brothers, sisters and grandchildren) who is a Planholder. An initial
charge of $5 is made for the second and each additional Planholder enrolled
under the Account.
   
Deposits of $25 or more may be made into the Transfer Account either on a
scheduled or nonscheduled basis. Funds may be transferred out of an Account to
make purchase payments under the Systematic Investment Plan, either in
accordance with a Transfer Schedule established by the Accountholder or on a
nonscheduled basis, and to purchase a variable annuity or fixed-dollar annuity
under the Program, and in certain circumstances to pay premiums under
Prudential insurance policies outside the Program. Withdrawals from the
Account may be made by written request. Prudential will credit interest as of
the end of each calendar quarter in which the average balance in the Transfer
Account during the quarter is $50 or more. The interest rate is determined
each year by Prudential's Board of Directors. The rate of interest for 1998 is
4.0%.     
 
                                      28
<PAGE>
 
SYSTEMATIC INVESTMENT PLAN DIFFERENCES
 
MINIMUM PURCHASE AMOUNT. Although the minimum initial purchase amount is $300,
as in the case of the revised Plan, the minimum amount of any subsequent
purchase is $100. As indicated in the discussion of the Transfer Account
above, purchases may be made on a scheduled basis from the Transfer Account,
but only if the schedule provides for purchases of at least $400 a year.
   
DETERMINING SALES CHARGE. In determining sales charge under Old Form Contracts
there is no provision for adding, to the dollar amount of the current
purchase, the value of shares already credited under the Plan, as described on
page 10 for the revised Plan. While the sales charge is thus determined
separately for each purchase payment, all nonscheduled transfers from the
Transfer Account on the same day as purchase payments for the Plans of spouses
and their children under the age of 21 will be considered a single purchase
payment for the purpose of determining the sales charge.     
 
There is no provision for Letter of Intent under Old Form Contracts.
 
ANNUITY RATE PROTECTION. Rights acquired under Old Form Contracts may be used
only on the life of the Planholder for whom they were purchased, in connection
with the purchase of either a fixed-dollar annuity or variable annuity under
the Program. These rights terminate upon the death of the Planholder or upon
termination of the Planholder's participation in the Program. The charge for
the rights acquired in respect to Plan purchases under Old Form Contracts is
not deducted from the Planholder's annual distribution, but instead is
deducted from the amount specified for transfer from the Transfer Account in
connection with a purchase under the Plan, before transferring the remainder
as the purchase payment.
   
DISTRIBUTIONS. Under Old Form Contracts, as with the revised Plan described
throughout this Prospectus, the amount of the Planholder's annual
distribution, after any deductions have been made from it, is ordinarily
applied at net asset value to increase the number of shares credited under the
Plan. As an alternative under Old Form Contracts, however, any such amount may
instead be distributed to the Planholder in cash if he/she or Prudential so
elects. As noted on page 13, the date of distribution will ordinarily occur
once a year in December.     
   
Deductions from the amount of distribution under Old Form Contracts consist of
the annual custodial charge and, for Plans issued in Maryland and New York,
any charge for the purchase of annuity rate protection rights as described in
the next to last paragraph under ANNUITY RATE PROTECTION on page 12. There is
no deduction for the cost of annuity rate protection rights acquired in
connection with purchases under the Plan since, as described in the previous
subsection, the charge for such rights is paid at the time the shares are
credited under Old Form Contracts.     
   
BENEFICIARY. Subject to the conditions specified in the first paragraph under
NAMING A BENEFICIARY on page 27, at the death of the Planholder under Old Form
Contracts, such number of the Planholder's securities shares as represent the
designated beneficiary's interest will be credited to that beneficiary. If the
designated beneficiary is not already a Planholder, Prudential will without
charge establish a Plan for the beneficiary and transfer the shares so
credited to that Plan. The Plan established will be the revised Systematic
Investment Plan.     
 
The preceding paragraph applies whether or not the beneficiary is a natural
person taking in his/her own right. There is no requirement under Old Form
Contracts for liquidation of the beneficiary's interest, with payment in cash,
when the beneficiary is not a natural person taking in his/her own right.
 
VARIABLE ANNUITY CONTRACT DIFFERENCES
   
Under the Fixed-Dollar Annuity and Annuity Rate Protection Contract included
among the Old Form Contracts, a fixed-dollar annuity (not described in this
Prospectus) is available. A fixed-dollar annuity purchase may be used in
combination with a variable annuity purchase to satisfy the initial minimum
purchase requirement described under PURCHASING A VARIABLE ANNUITY on page 14,
and either a fixed-dollar or a variable annuity or a combination of both may
be used to satisfy the subsequent purchase minimum described in the same
section.     
   
DETERMINATION OF SALES CHARGE. There are three differences between the manner
in which the sales charge for an annuity purchase under the Old Form Contracts
is determined and that described under SALES AND OTHER CHARGES on page 15.
    
First, current and previous fixed-dollar annuity purchases under the Program
are combined with variable annuity purchases in determining the applicable
sales charge rate. Second, purchases made by a husband and wife are combined
in determining the sales charge rate, but not purchases by or for their
children. Finally, the lower sales
 
                                      29
<PAGE>
 
   
charges for purchases made with the proceeds of Plan liquidations apply to any
such proceeds credited to the Transfer Account within three months after
liquidation, no matter when they may subsequently be transferred to purchase
an annuity.     
   
GRADUAL INVESTMENT PURCHASE OF VARIABLE ANNUITY. For Planholders with Old Form
Contracts, Prudential provides an alternative arrangement under which a person
who purchases a variable annuity with no accumulation period may do so by
starting out with a fixed-dollar annuity and converting it gradually over a
36-month period, a 1/36th portion in each month, to a variable annuity. This
gradual conversion arrangement permits the purchaser to reduce the chance of
making the purchase at a time when the value of common stock may be relatively
high, by making in effect 36 separate investments in the Account. Of course,
this also reduces the chance of investing in annuity shares at a time when the
value of common stocks may be relatively low. The 5% rate schedule is not
available with gradual conversion.     
   
RATE SCHEDULES. In the revised form of Contract, as described under HOW
VARIABLE ANNUITY PAYMENTS ARE DETERMINED on page 17, the 3.5% schedule applies
in only a few states where the 5% schedule is not available under state law.
Under Old Form Contracts the 3.5% schedule is also available as an alternative
to the 5% schedule in the states where the 5% schedule is available.     
 
In those states, the 5% schedule will be used for a variable annuity purchase
unless the 3.5% schedule is specifically requested. However, the 5% schedule
is not available where the gradual investment arrangement is chosen, or for a
fixed-dollar annuity purchase under the Program.
   
THE CONTINUING RIGHT TO PURCHASE AN ANNUITY. In addition to the assurances
described under this heading beginning on page 19, Old Form Contract
Planholders who own other contracts issued by Prudential on the date of notice
of an intention to discontinue providing variable annuities may exchange those
contracts for variable annuities even if the 90-day period has expired, but
only to the extent of the Planholder's interest in such other contracts on the
date of the notice.     
 
STATE REGULATION
          
Prudential is subject to regulation and supervision by the Department of
Insurance of the State of New Jersey, which periodically examines its
operations and financial condition. It is also subject to the insurance laws
and regulations of all jurisdictions in which it is authorized to do business.
       
Prudential is required to submit annual statements of its operations,
including financial statements, to the insurance departments of the various
jurisdictions in which it does business to determine solvency and compliance
with local insurance laws and regulations.     
   
In addition to the annual statements referred to above, Prudential is required
to file with New Jersey and other jurisdictions a separate statement with
respect to the operations of all its variable contract accounts, in a form
promulgated by the National Association of Insurance Commissioners.     
 
FEDERAL INCOME TAXES
 
PRUDENTIAL'S GIBRALTAR FUND, INC. Under the provisions of the Internal Revenue
Code applicable to regulated investment companies, the Fund, by distributing
substantially all of its net investment income and realized capital gains,
will be relieved of federal income tax on the income and gains so distributed.
The Fund has qualified for such tax treatment and intends to continue to so
qualify. Qualification of the Fund as a regulated investment company
 
                                      30
<PAGE>
 
   
does not involve government supervision of management or of investment
practices or policies. See DESCRIPTION OF FUND SHARES AND VOTING RIGHTS on
page 26. There is a 4% excise tax on a portion of the undistributed income of
a regulated investment company if that company fails to distribute required
percentages of its ordinary income and capital gain net income. The Fund
intends to employ practices that will eliminate or minimize the imposition of
this excise tax.     
   
PRUDENTIAL'S INVESTMENT PLAN ACCOUNT. For federal income tax purposes,
Prudential's IPA is a separate entity taxable as a corporation. The Account
has qualified under the provisions of Subchapter M of the Internal Revenue
Code, and it is expected that it will continue to so qualify. As with the
Fund, the Account, by distributing substantially all of the net investment
income and realized capital gains, will not be subject to federal income tax
on the income and gains so distributed. As with the Fund, the Account intends
to employ practices that will eliminate or minimize the 4% excise tax. See
DISTRIBUTIONS on page 13. Neither the custodian nor the Account bears any
portion of any federal income taxes levied or assessed against either with
respect to shares of the Account credited to Planholders, or with respect to
the operations of the Program, the income from such shares or the transfer or
liquidation of such shares. Any liquidation or transfer of a Planholder's
shares in accordance with the provisions of the Plan Contract shall be deemed
made on behalf of the Planholder and any federal income taxes payable as a
result shall be borne by the Planholder.     
 
Distributions of net investment income from the Account to Planholders are
taxable to each Planholder at ordinary income rates. Any capital gains
dividend distributions from the Account to Planholders are taxable to each
Planholder as long-term capital gains.
   
PRUDENTIAL'S ANNUITY PLAN ACCOUNT. The operations of Prudential's APA form a
part of, and are taxed with, the operations of Prudential. No federal income
tax is currently payable on distributions of income received on the Fund
shares held in the Account for the benefit of Planholders, on capital gains
realized by Prudential on redemptions of Fund shares, or on capital gains
dividends received by the Account from the Fund. Accordingly, the annuity
share value is not affected by income and capital gains distributions. These
distributions are reinvested in the Fund and are not distributed to
Planholders. Consequently, the Planholder is subject to federal income tax on
his/her variable annuity only when he/she receives monthly annuity payments or
if he/she cancels his/her annuity (see CANCELING THE ANNUITY, page 19). A
portion of each monthly annuity payment is excluded from gross income until
the total investment in the contract is recovered. The portion of each payment
to be excluded is determined by dividing the investment in the contract by the
annuitant's life expectancy, with an adjustment for a Type B Annuity being
made to reflect the 10-year certain feature. The payments in excess of this
excluded portion are taxable as ordinary income. If the Planholder cancels
his/her annuity, any gain on the cancellation is taxable as ordinary income.
Should annuity payments cease on account of the death of the annuitant before
purchase payments have been fully recovered the annuitant, on his or her last
tax return, (or in certain cases the beneficiary) is allowed a deduction for
the unrecovered amount.     
   
Taxable payments under the Contract will generally be subject to withholding
by Prudential. Recipients of pensions and annuities may elect for withholding
not to apply.     
 
The above discussion of the federal income tax status under these Contracts is
not complete and is not intended as tax advice nor does it consider any
applicable state or other tax laws. A qualified tax advisor should be
consulted for complete information and advice.

LITIGATION
   
On October 28, 1996, Prudential entered into a Stipulation of Settlement in a
multidistrict proceeding involving allegations of various claims relating to
Prudential's life insurance sales practices. (In re Prudential Insurance
Company of America Sales Practices Litigation, D.N.J., MDL No. 1061, Master
Docket No. 95-4704 (AMW).) On March 7, 1997, the United States District Court
for the District of New Jersey approved the Stipulation of Settlement as fair,
reasonable and adequate, and later issued a Final Order and Judgment in the
consolidated class actions before the Court, 962 F. Supp. 450 (March 17, 1997,
as amended April 14, 1997). The Court's Final Order and Judgment approving the
class Settlement has been appealed to the United States Court of Appeals for
the Third Circuit, which held a hearing on January 26, 1998. The Court has not
yet issued a ruling on the appeal.     
          
Pursuant to the Settlement, Prudential agreed to provide and has begun to
implement an Alternative Dispute Resolution (ADR) process for class members
who believe they were misled concerning the sale or performance of their life
insurance policies. Management now has information which allows for
computation of a reasonable estimate of losses associated with ADR claims.
Based on this information, management estimated the cost of remedying
policyholder claims in the ADR process before taxes to be approximately $2.05
billion. While management believes these to be reasonable estimates based on
information currently available, the ultimate amount of the total cost of
remedied policyholder claims is dependent on complex and varying factors,
including actual claims by eligible policyholders, the relief options chosen
and the dollar value of those options. There are also additional elements of
the ADR process which cannot be fully evaluated at this time (e.g., claims
which may be successfully appealed) which could increase this estimate.     
   
In addition, a number of actions have been filed against Prudential by
policyowners who have excluded themselves from the Settlement; Prudential
anticipates that additional suits may be filed by other policyowners.     
   
Also, on July 9, 1996, a Multi-State Life Insurance Task Force comprised of
insurance regulators from 29 states and the District of Columbia, released a
report on Prudential's activities. As of February 24, 1997, Prudential had
entered into consent orders or agreements with all 50 states and the District
of Columbia to implement a remediation plan, whose terms closely parallel the
Settlement approved in the MDL proceeding, and agreed to a series of payments
allocated to all 50 states and the District of Columbia amounting to a total
of approximately $65 million. These agreements are now being implemented
through Prudential's implementation of the class Settlement.     
   
Litigation is subject to many uncertainties, and given the complexity and
scope of these suits, their outcome cannot be predicted. It is also not
possible to predict the likely results of any regulatory inquiries or their
effect on litigation which might be initiated in response to widespread media
coverage of these matters.     
   
Accordingly, management is unable to make a meaningful estimate of the amount
or range of loss that could result from an unfavorable outcome of all pending
litigation and regulatory inquiries. It is possible that the results of
operations or the cash flow of Prudential, in particular quarterly or annual
periods could be materially affected by an ultimate unfavorable outcome of
certain pending litigation and regulatory matters. Management believes,
however, that the ultimate outcome of all pending litigation and regulatory
matters referred to above should not have a material adverse effect on
Prudential's financial position, after consideration of applicable reserves.
       
YEAR 2000     
   
The services provided to the Contract owners by Prudential, PIMS and Prusec
depend on the smooth functioning of their respective computer systems. The
year 2000, however, holds the potential for a significant disruption in the
operation of these systems. Many computer programs cannot distinguish the year
2000 from the year 1900 because of the way in which dates are encoded. Left
uncorrected, the year "00" could cause systems to perform date comparisons and
calculations incorrectly that in turn could compromise the integrity of
business records and lead to serious interruption of business processes.     
   
Prudential identified this issue as a critical priority in 1995 and has
established quality assurance procedures including a certification process to
monitor and evaluate enterprise-wide conversion and upgrading of systems for
"Year 2000" compliance. Prudential has also initiated an analysis of potential
exposure that could result from the failure of major service providers such as
suppliers, custodians and brokers, to achieve Year 2000 compliance.     
 
                                      32
<PAGE>
 
   
Prudential expects to complete its adaptation, testing and certification of
software for Year 2000 compliance by December 31, 1998. During 1999,
Prudential plans to conduct additional internal testing, to participate in
securities industry-wide test efforts and to complete major service provider
analysis and contingency planning.     
   
The expenses of Prudential's Year 2000 compliance are allocated across its
various businesses, including those businesses not engaged in providing
services to Planholders. Accordingly, while the expense is substantial in the
aggregate, it is not expected to have a material impact on the ability of
Prudential, PIMS and Prusec to meet their contractual commitments to
Planholders.     
   
Prudential believes that it is well positioned to achieve the necessary
modifications and mitigate Year 2000 risks. However, if such efforts are not
completed on a timely basis, the Year 2000 issue could have a material adverse
impact on Prudential's operations, those of its subsidiary and affiliate
companies and/or its separate accounts such as IPA and APA. Moreover, there
can be no assurance that the measures taken by Prudential's external service
providers will be sufficient to avoid any material adverse impact on
Prudential's operations or those of its subsidiary and affiliate companies.

* These members of the Board are interested persons of Prudential, its
  affiliates or the Fund as defined in the 1940 Act. Certain actions of the
  Board, including the annual continuance of the Investment Advisory Contract
  between the Fund and Prudential, must be approved by a majority of the
  members of the Board who are not interested persons of Prudential, its
  affiliates or the Fund. Mr. Melzer and Mr. Greene, two of the five members
  of the Board, are interested persons of Prudential and the Fund, as that
  term is defined in the 1940 Act, because they are officers and/or affiliated
  persons of Prudential, the investment advisor to the Fund. Messrs. Fenster,
  McDonald and Weber are not interested persons of Prudential, its affiliates
  or the Fund. However, Mr. Fenster is President of the New Jersey Institute

                      FOR THE YEAR ENDED DECEMBER 31, 1997


PRUDENTIAL'S INVESTMENT PLAN ACCOUNT
- ------------------------------------

NOTE 1: GENERAL

        The Investment Plan Account (the "Account") was established on June 11,
        1968, by resolution of Prudential's Board of Directors, as a separate
        variable contract account of The Prudential Insurance Company of America
        ("Prudential") under the laws of the State of New Jersey. It is
        administered by Prudential under the general direction of Prudential's
        officers and managerial staff. The Account is registered with the
        Securities and Exchange Commission under the Investment Company Act of
        1940, as amended (1940 Act), as a unit investment trust. Registration
        does not imply supervision by the Securities and Exchange Commission of
        the management or investment policies and practices of the Account or
        Prudential. The assets of the Account are invested in shares of
        Prudential's Gibraltar Fund (the "Fund") at the net asset value without
        sales load.

        PRUDENTIAL'S GIBRALTAR FUND

        The Fund was incorporated in the State of Delaware on March 14, 1968. It
        is registered under the 1940 Act as a diversified open-end management
        investment company. Registration does not imply supervision by the
        Securities and Exchange Commission of the management or investment
        policies and practices of the Fund or Prudential. The Board of Directors
        of the Fund is responsible for the management of the Fund and, in
        addition to reviewing the actions of the Fund's investment advisor,
        decides upon matters of general policy. The Fund's officers conduct and
        supervise the daily business operations of the Fund.

NOTE 2: SIGNIFICANT ACCOUNTING POLICIES

        The accompanying financial statements are prepared in conformity with
        generally accepted accounting principles (GAAP). The preparation of the
        financial statements in conformity with GAAP requires management to make
        estimates and assumptions that affect the reported amounts and
        disclosures. Actual results could differ from those estimates.

        Investment--The investment in shares of the Fund is stated at the net
        asset value. 

        Security Transactions--Realized gains and losses on security
        transactions are reported on an identified cost basis. Purchase and
        sale transactions are recorded as of the trade date of the security
        being purchased or sold.

        Distributions Received--Dividend and capital gain distributions
        received are reinvested in additional shares of the Fund and are
        recorded on the ex-dividend date.

NOTE 3: ADMINISTRATION CHARGES

        The Administration charge is applied daily against the net assets of the
        Account at an effective annual rate of 0.75% for the first $250 million
        in assets and 0.55% for the second $250 million in assets. This charge,
        which is paid to Prudential, includes costs associated with issuing the
        Contract, establishing and maintaining records, and providing reports to
        Contract owners. For the year ended December 31, 1997, the amount of
        this charge paid to Prudential was $1,881,638.

NOTE 4: TAXES

        For federal income tax purposes, Prudential's Investment Plan Account is
        a separate entity taxable as a corporation, and as such has elected to
        be taxed as a regulated investment company under Subchapter M of the
        Internal Revenue Code. As a result, by distributing substantially all of
        its net investment income and net realized capital gains, the Account
        will not be subject to federal income tax on the investment income and
        capital gains so distributed.

                        REPORT OF INDEPENDENT ACCOUNTANTS


To the Contract Owners of
Prudential's Investment Plan Account
and the Board of Directors of
The Prudential Insurance Company of America

In our opinion, the accompanying statement of net assets and the related
statements of operations and of changes in net assets present fairly, in all
material respects, the financial position of Prudential's Investment Plan
Account at December 31, 1997, the results of its operations for the year then
ended and the changes in its net assets for each of the two years in the period
then ended, in conformity with generally accepted accounting principles. These
financial statements are the responsibility of The Prudential Insurance Company
of America's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
financial statements in accordance with generally accepted auditing standards
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of shares owned in Prudential's Gibraltar Fund, Inc. at December
31, 1997, provide a reasonable basis for the opinion expressed above.

      ("Prudential") under the laws of the State of New Jersey. It is
      administered by Prudential under the general direction of Prudential's
      officers and managerial staff. The Account is registered with the
      Securities and Exchange Commission under the Investment Company Act of
      1940, as amended (1940 Act), as a unit investment trust. Registration does
      not imply supervision by the Securities and Exchange Commission of the
      management or investment policies and practices of the Account or
      Prudential. The assets of the Account are invested in shares of
      Prudential's Gibraltar Fund (the "Fund") at the net asset value without
      sales load.

      PRUDENTIAL'S GIBRALTAR FUND

      The Fund was incorporated in the State of Delaware on March 14, 1968. It
      is registered under the 1940 Act as a diversified open-end management
      investment company. Registration does not imply supervision by the
      Securities and Exchange Commission of the management or investment
      policies and practices of the Fund or Prudential. The Board of Directors
      of the Fund is responsible for the management of the Fund and, in addition
      to reviewing the actions of the Fund's investment advisor, decides upon
      matters of general policy. The Fund's officers conduct and supervise the
      daily business operations of the Fund.

NOTE 2: SIGNIFICANT ACCOUNTING POLICIES

      The accompanying financial statements are prepared in conformity with
      generally accepted accounting principles (GAAP). The preparation of the
      financial statements in conformity with GAAP requires management to make
      estimates and assumptions that affect the reported amounts and
      disclosures. Actual results could differ from those estimates.

      Investment--The investment in shares of the Fund is stated at the net
      asset value.

      Security Transactions--Realized gains and losses on security
      transactions are reported on an identified cost basis. Purchase and sale
      transactions are recorded as of the trade date of the security being
      purchased or sold.

      Distributions Received--Dividend and capital gain distributions received
      are reinvested in additional shares of the Fund and are recorded on the

      A. Mortality Risk and Expense Risk Charges

      The mortality risk and expense risk charge, at an effective annual rate of
      0.075% and 0.150%, respectively, are applied daily against the net assets
      of the Account. Mortality risk is that annuitants may live longer than
      estimated and expense risk is that the cost of issuing and administering
      the policies may exceed the estimated expenses. For the year ended
      December 31, 1997, the amount of these charges paid to Prudential was
      $5,190.

      owners. For the year ended December 31, 1997, the amount of this charge
      paid to Prudential was $3,461.

NOTE 4: TAXES

      Prudential is taxed as a "life insurance company" as defined by the
      Internal Revenue Code and the results of operations of the Account form a
      part of Prudential's consolidated federal tax return. Under current

      no provision for tax liability has been recorded in these financial
      statements.

      The decrease in net assets resulting from equity transfers represents the
      net withdrawals of Prudential from the Account.

      in the Fund for the year ended December 31, 1997 were as follows:

                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Contract Owners of
Prudential's Annuity Plan Account
and the Board of Directors of
The Prudential Insurance Company of America

In our opinion, the accompanying statement of net assets and the related
statements of operations and of changes in net assets present fairly, in all
material respects, the financial position of Prudential's Annuity Plan Account
at December 31, 1997, the results of its operations for the year then ended and
the changes in its net assets for each of the two years in the period then
ended, in conformity with generally accepted accounting principles. These
financial statements are the responsibility of The Prudential Insurance Company
of America's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
financial statements in accordance with generally accepted auditing standards
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of shares owned in Prudential's Gibraltar Fund, Inc. at December
31, 1997, provide a reasonable basis for the opinion expressed above.

                     NOTES TO THE FINANCIAL STATEMENTS OF
                          PRUDENTIAL'S GIBRALTAR FUND

             General

             Prudential's Gibraltar Fund (the "Fund") was originally
             incorporated in the State of Delaware on March 14, 1968 and was
             reincorporated in the State of Maryland effective May 1, 1997. It
             is registered as an open-end, diversified management investment
             company under the Investment Company Act of 1940, as amended. The
             Fund was organized by The Prudential Insurance Company of America
             (The Prudential) to serve as the investment medium for the variable
             contracts accounts of The Prudential Financial Security Program.
             The Fund does not sell its shares to the public. The accounts will
             redeem shares of the Fund to the extent necessary to provide
             benefits under the contracts or for such other purposes as may be
             consistent with the contracts.

Note 1:      Accounting Policies

             The following is a summary of significant accounting policies
             followed by the fund in the preparation of its financial
             statements.

             Securities Valuation: Securities traded on a national securities
             exchange are valued at the last sales price (or the last bid price
             if there were no sales of the security that day) on the New York
             Stock Exchange, or if not traded on such exchange, such last sales
             or bid price at the time of close of the New York Stock Exchange on
             the principal exchange on which such securities are traded. For any
             securities not traded on a national securities exchange but traded
             in the over-the-counter market, the value is the last bid price
             available, except that securities for which quotations are
             furnished through a nationwide automated quotation system approved
             by the National Association of Securities Dealers, Inc. (NASDAQ)
             are valued at the closing best bid price on the date of valuation
             provided by a pricing service which utilizes NASDAQ quotations.

             Short-term securities which mature in more than 60 days are valued
             at current market quotations, Short-term securities which mature in
             60 days or less are valued at amortized cost which approximates
             market value.

             In connection with transactions in repurchase agreements with U.S.
             financial institutions, it is the Fund's policy that its custodian
             or designated subcustodians, as the case may be under triparty
             repurchase agreements, take possession of the underlying collateral
             securities, the value of which exceeds the principal amount of the
             repurchase transaction, including accrued interest. If the seller
             defaults and the value of the collateral declines or if bankruptcy
             proceedings are commenced with respect to the seller of the
             security, realization of the collateral by the Fund may be delayed
             or limited.

             Securities Transactions and Net Investment Income: Securities
             transactions are recorded on the trade date. Realized gains and
             losses on sales of investments are calculated on the identified
             cost basis. Dividend income is recorded on the ex-dividend date and
             interest income is recorded on the accrual basis. Expenses are
             recorded on the accrual basis which may require the use of certain
             estimates by management.

             Dividends and Distributions: Dividends from net investment income
             are declared and paid semi-annually. The Fund will distribute at
             least annually net capital gains in excess of capital loss
             carryforwards, if any. Dividends and distributions are recorded on
             the ex-dividend date. Dividends from net investment income and net
             realized capital gains of the Fund will normally be declared and
             reinvested in additional full and fractional shares twice a year.
             Some dividends are paid in cash. ,

             Income distributions and capital gain distributions are determined
             in accordance with income tax regulations which may differ from
             generally accepted accounting principles.

             Taxes: It is the Fund's policy to continue to meet the requirements
             of the Internal Revenue Code applicable to regulated investment
             companies and to distribute all of its taxable net income to its
             shareholders. Therefore, no federal income tax provision is
             required. State franchise taxes were paid for the period that the
             Fund was incorporated in Delaware. No such commitments exist
             following reincorporation in Maryland. Withholding taxes on foreign
             dividends have been provided for in accordance with the Fund's
             understanding of the applicable country's tax rules and rates.

             Reclassification of Capital Accounts: The Fund accounts and reports
             for distributions to shareholders in accordance with the American
             Institute of Certified Public Accountants (A.I.C.PA.). Statement of
             Position 93- 2: Determination, Disclosure, and Financial Statement
             Presentation of Income, Capital Gain, and Return of Capital
             Distributions by Investment Companies. The effect of applying this
             statement was to decrease undistributed net investment income by
             $42,059, increased net realized gains by $2,789 and increased
             paid-in capital in excess of par by $39,270. In addition the Fund
             reclassified $199,247 of dividends in excess of net investment
             income to accumulated capital gain. Such reclassifications had no
             effect on net assets, results of operations, or net asset value per
             share.

Note 2:Investment Advisory Fee and Other Transactions with Affiliates

             Investment Advisory Fee:

            
             The investment advisory fee,whichis computed daily at an effective
             annual rate of 0.1 25% of the net assets of the Fund, is payable
             quarterly to The Prudential Insurance Company of America ("The
             Prudential") as required under the investment advisory agreement.
             The Prudential pays all expenses of the Fund except for fees and
             expenses of those members of the Fund's Board of Directors who are
             not officers or employees of The Prudential and its affiliates;
             transfer and any other local, state or federal taxes; and brokers'
             commissions and other fees and charges attributable to investment
             transactions.

             During the year ended December 31, 1997, Prudential Securities
             Incorporated, an affiliate of The Prudential, earned approximately
             $25,000 in brokerage commissions as a result of executing
             transactions in portfolio securities on behalf of the Fund.

Note 3: Portfolio Securities

             Purchases and sales of investment securities, other than short-term
             investments, for the year ended December 31, 1997 aggregated
             $297,205,094 and $303,041,488, respectively.

             The federal income tax basis of the Fund's investments at December
             31, 1997 was substantially the same as for financial reporting
             purposes, $276,988,335 and, accordingly, net unrealized
             appreciation for federal income tax purposes was $45,664,149 (gross
             unrealized appreciation $57,881,924; gross unrealized depreciation
             $12,217,775).

                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Shareholders of Prudential's Gibraltar Fund, Inc.

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Prudential's Gibraltar Fund, Inc.
(the "Fund") at December 31, 1997, the results of its operations for the year
then ended and the changes in its net assets and the financial highlights for
the two years in the period then ended, in conformity with generally accepted
accounting principles. These financial statements and financial highlights
(hereafter referred to as "financial statements") are the responsibility of the
Fund's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
financial statements in accordance with generally accepted auditing standards
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at December 31, 1997 by correspondence with the
custodian and brokers and the application of alternative auditing procedures
where confirmations from brokers were not received, provide a reasonable basis
for the opinion expressed above. The financial highlights for each of the three
years in the period ended December 31, 1995 were audited by other independent
accountants whose report thereon dated February 15, 1996 expressed an
unqualified opinion on those statements.

                   THE PRUDENTIAL INSURANCE COMPANY OF AMERICA

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  BUSINESS

    The Prudential Insurance Company of America and its subsidiaries
    (collectively, "the Company") provide insurance and financial services
    throughout the United States and many locations worldwide. Principal
    products and services provided include life and health insurance, annuities,
    pension and retirement related investments and administration, managed
    healthcare, property and casualty insurance, securities brokerage, asset
    management, investment advisory services and real estate brokerage.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    BASIS OF PRESENTATION

    The consolidated financial statements include the accounts of the Prudential
    Insurance Company of America, a mutual life insurance company, and its
    subsidiaries, and those partnerships and joint ventures in which the Company
    has a controlling interest. The consolidated financial statements have been
    prepared in accordance with generally accepted accounting principles
    ("GAAP"). All significant intercompany balances and transactions have been
    eliminated.

    USE OF ESTIMATES

    The preparation of financial statements in conformity with GAAP requires
    management to make estimates and assumptions that affect the reported
    amounts of assets and liabilities and disclosure of contingent assets and
    liabilities at the date of the financial statements and the reported amounts
    of revenues and expenses during the period. Actual results could differ from
    those estimates.

    INVESTMENTS

    FIXED MATURITIES classified as "available for sale" are carried at estimated
    fair value. Fixed maturities that the Company has both the positive intent
    and ability to hold to maturity are stated at amortized cost and classified
    as "held to maturity." The amortized cost of fixed maturities are written
    down to estimated fair value when considered impaired and the decline in
    value is considered to be other than temporary. Unrealized gains and losses
    on fixed maturities "available for sale," net of income tax, the effect on
    deferred policy acquisition costs and participating annuity contracts that
    would result from the realization of unrealized gains and losses, are
    included in a separate component of equity, "Net unrealized investment
    gains."

    TRADING ACCOUNT ASSETS are carried at estimated fair value.

    EQUITY SECURITIES, available for sale, comprised of common and
    non-redeemable preferred stock, are carried at estimated fair value. The
    associated unrealized gains and losses, net of income tax, the effect on
    deferred policy acquisition costs and participating annuity contracts that
    would result from the realization of unrealized gains and losses, are
    included in a separate component of equity, "Net unrealized investment
    gains."

     MORTGAGE LOANS ON REAL ESTATE are stated primarily at unpaid principal
     balances, net of unamortized discounts and allowance for losses on impaired
     loans. Impaired loans are identified by management as loans in which a
     probability exists that all amounts due according to the contractual terms
     of the loan agreement will not be collected. Impaired loans are measured
     based on the present value of expected future cash flows, discounted at the
     loan's effective interest rate or the fair value of the collateral, if the
     loan is collateral dependent. The Company's periodic evaluation of the
     adequacy of the allowance for losses is based on a number of factors,
     including past loan loss experience, known and inherent risks in the
     portfolio, adverse situations that may affect the borrower's ability to
     repay, the estimated value of the underlying collateral, composition of the
     loan portfolio, current economic conditions and other relevant factors.
     This evaluation is inherently subjective as it requires estimating the
     amounts and timing of future cash flows expected to be received on impaired
     loans.

    Interest received on impaired loans, including loans that were previously
    modified in a troubled debt restructuring, is either applied against the
    principal or reported as revenue, according to management's judgment as to
    the collectibility of principal. Management discontinues the accrual of
    interest on impaired loans after the loans are 90 days delinquent as to
    principal or interest or earlier when management has serious doubts about
    collectibility. When a loan is recognized as

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)


    impaired, any accrued but unpaid interest previously recorded on such loan
    is reversed against interest income of the current period. Generally, a loan
    is restored to accrual status only after all delinquent interest and
    principal are brought current and, in the case of loans where interest has
    been interrupted for a substantial period, a regular payment performance has
    been established.

    INVESTMENT REAL ESTATE, which the Company has the intent to hold for the
    production of income, is carried at depreciated cost less any write-downs to
    fair value for impairment losses. Depreciation on real estate is computed
    using the straight-line method over the estimated lives of the properties.
    Real estate to be disposed of is carried at the lower of depreciated cost or
    fair value less selling costs and is not depreciated once classified as
    such.

    POLICY LOANS are carried at unpaid principal balances.

    SECURITIES PURCHASED UNDER AGREEMENTS TO RESELL AND SECURITIES SOLD UNDER
    AGREEMENTS TO REPURCHASE are carried at the amounts at which the securities
    will be subsequently resold or reacquired, including accrued interest, as
    specified in the respective agreements. The Company's policy is to take
    possession of securities purchased under agreements to resell. The market
    value of securities to be repurchased is monitored, and additional
    collateral is requested, where appropriate, to protect against credit
    exposure.

    SECURITIES BORROWED AND SECURITIES LOANED are recorded at the amount of cash
    advanced or received. With respect to securities loaned, the Company obtains
    collateral in an amount equal to 102% and 105% of the fair value of the
    domestic and foreign securities, respectively. The Company monitors the
    market value of securities borrowed and loaned on a daily basis with
    additional collateral obtained as necessary. Non-cash collateral received is
    not reflected in the Consolidated Statements of Financial Position.
    Substantially, all the Company's securities borrowed contracts are with
    other brokers and dealers, commercial banks and institutional clients.
    Substantially, all of the Company's securities loaned are with large
    brokerage firms.

    These transactions are used to generate net investment income and facilitate
    trading activity. These instruments are short-term in nature (usually 30
    days or less) and are collateralized principally by U.S. Government and
    mortgage-backed securities. The carrying amounts of these instruments
    approximate fair value because of the relatively short period of time
    between the origination of the instruments and their expected realization.

    SHORT-TERM INVESTMENTS, including highly liquid debt instruments purchased
    with an original maturity of twelve months or less, are carried at amortized
    cost, which approximates fair value.

    OTHER LONG-TERM INVESTMENTS primarily represent the Company's investments
    in joint ventures and partnerships in which the Company does not have
    control and derivatives held for purposes other than trading. Joint venture
    and partnership investments are recorded using the equity method of
    accounting, reduced for other than temporary declines in value.

    REALIZED INVESTMENT GAINS, NET are computed using the specific
    identification method. Costs of fixed maturities and equity securities are
    adjusted for impairments considered to be other than temporary. Allowances
    for losses on mortgage loans on real estate are netted against asset
    categories to which they apply and provisions for losses on investments are
    included in "Realized investment gains, net." Unrealized gains and losses on
    trading account assets are included in "Commissions and other income."

    CASH

    Cash includes cash on hand, amounts due from banks, and money market
    instruments.

    DEFERRED POLICY ACQUISITION COSTS

    The costs which vary with and that are related primarily to the production
    of new insurance business are deferred to the extent such costs are deemed
    recoverable from future profits. Such costs include certain commissions,
    costs of policy issuance and underwriting, and certain variable field office
    expenses. Deferred policy acquisition costs are subject to recoverability
    testing at the time of policy issue and loss recognition testing at the end
    of each accounting period. Deferred policy acquisition costs are adjusted
    for the impact of unrealized gains or losses on investments as if these
    gains or losses had been realized, with corresponding credits or charges
    included in equity.

                   THE PRUDENTIAL INSURANCE COMPANY OF AMERICA

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)


    For life insurance, deferred policy acquisition costs are amortized over the
    expected life of the contracts (up to 45 years) in proportion to estimated
    gross margins based on historical and anticipated future experience, which
    is updated periodically. The effect of changes in estimated gross margins is
    reflected in earnings in the period they are revised. Policy acquisition
    costs related to interest-sensitive products and certain investment-type
    products are deferred and amortized over the expected life of the contracts
    (periods ranging from 15 to 30 years) in proportion to estimated gross
    profits arising principally from investment results, mortality and expense
    margins and surrender charges based on historical and anticipated future
    experience, updated periodically. The effect of revisions to estimated gross
    profits on unamortized deferred acquisition costs is reflected in earnings
    in the period such estimated gross profits are revised.

    For property and casualty contracts, deferred policy acquisition costs are
    amortized over the period in which related premiums are earned. Future
    investment income is considered in determining the recoverability of
    deferred policy acquisition costs.

    For disability insurance, health insurance, group life insurance and most
    group annuities, acquisition costs are expensed as incurred.

    POLICYHOLDERS' DIVIDENDS

    The amount of the dividends to be paid to policyholders is determined
    annually by the Company's Board of Directors. The aggregate amount of
    policyholders' dividends is related to actual interest, mortality,
    morbidity, persistency and expense experience for the year and judgment as
    to the appropriate level of statutory surplus to be retained by the Company.

    SEPARATE ACCOUNT ASSETS AND LIABILITIES

    Separate Account assets and liabilities are reported at estimated fair value
    and represent segregated funds which are invested for certain policyholders,
    pension fund and other customers. The assets consist of common stocks, fixed
    maturities, real estate related securities, real estate mortgage loans and
    short-term investments. The assets of each account are legally
    segregated and are not subject to claims that arise out of any other
    business of the Company. Investment risks associated with market value
    changes are generally borne by the customers, except to the extent of
    minimum guarantees made by the Company with respect to certain accounts. The
    investment income and gains or losses for Separate Accounts generally accrue
    to the policyholders and are not included in the Consolidated Statement of
    Operations. Mortality, policy administration and surrender charges on the
    accounts are included in "Policy charges and fee income."

    INSURANCE REVENUE AND EXPENSE RECOGNITION

    Premiums from participating insurance policies are generally recognized when
    due. Benefits are recorded as an expense when they are incurred. A liability
    for future policy benefits is recorded using the net level premium method.

    Premiums from non-participating group annuities with life contingencies are
    generally recognized when due. For single premium immediate annuities and
    structured settlements, premiums are recognized when due with any excess
    profit deferred and recognized in a constant relationship to insurance
    in-force or, for annuities, the amount of expected future benefit payments.

    Amounts received as payment for interest sensitive investment contracts,
    deferred annuities and participating group annuities are reported as
    deposits to "Policyholders' account balances." Revenues from these contracts
    are reflected in "Policy charges and fee income" and consist primarily of
    fees assessed during the period against the policyholders' account balances
    for mortality charges, policy administration charges, surrender charges and
    interest earned from the investment of these account balances. Benefits and
    expenses for these products include claims in excess of related account
    balances, expenses of contract administration, interest credited and
    amortization of deferred policy acquisition costs.

    For disability insurance, group life insurance, health insurance and
    property and casualty insurance, premiums are recognized over the period to
    which the premiums relate in proportion to the amount of insurance
    protection provided. Claim and claim adjustment expenses are recognized when
    incurred.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)


    FOREIGN CURRENCY TRANSLATION ADJUSTMENTS

    Assets and liabilities of foreign operations and subsidiaries reported in
    other than U.S. dollars are translated at the exchange rate in effect at the
    end of the period. Revenues, benefits and other expenses are translated at
    the average rate prevailing during the period. Translation adjustments
    arising from the use of differing exchange rates from period to period are
    charged or credited directly to equity. The cumulative effect of changes in
    foreign exchange rates are included in "Foreign currency translation
    adjustments."

    COMMISSIONS AND OTHER INCOME

    Commissions and other income principally includes securities and
    commodities, commission revenues, asset management fees, investment banking
    revenue and realized and unrealized gains on trading account assets of the
    Company's broker-dealer subsidiary.

    DERIVATIVE FINANCIAL INSTRUMENTS

    Derivatives include swaps, forwards, futures, options and loan commitments
    subject to market risk, all of which are used by the Company in both trading
    and other than trading activities. Income and expenses related to
    derivatives used to hedge are recorded on the accrual basis as an adjustment
    to the carrying amount or to the yield of the related assets or liabilities
    over the periods covered by the derivative contracts. Gains and losses
    relating to early terminations of interest rate swaps used to hedge are
    deferred and amortized over the remaining period originally covered by the
    swap. Gains and losses relating to derivatives used to hedge the risks
    associated with anticipated transactions are deferred and utilized to adjust
    the basis of the transaction once it has closed. If it is determined that
    the transaction will not close, such gains and losses are included in
    "Realized investment gains, net."

    DERIVATIVES HELD FOR TRADING PURPOSES are used in the Company's securities
    broker-dealer business and in a limited-purpose swap subsidiary to meet the
    risk management needs of its customers by structuring transactions that
    allow customers to manage their exposure to interest rates, foreign exchange
    rates, indices or prices of securities and commodities and when possible,
    matched trading positions are established to minimize risk to the Company.
    Derivatives used for trading purposes are recorded at fair value as of the
    reporting date. Realized and unrealized changes in fair values are included
    in "Commissions and other income" in the period in which the changes occur.

    DERIVATIVES HELD FOR PURPOSES OTHER THAN TRADING are primarily used to hedge
    or reduce exposure to interest rate and foreign currency risks associated
    with assets held or expected to be purchased or sold, and liabilities
    incurred or expected to be incurred. Additionally, other than trading
    derivatives are used to change the characteristics of the Company's
    asset/liability mix consistent with the Company's risk management
    activities.

    INCOME TAXES

    The Company and its domestic subsidiaries file a consolidated federal income
    tax return. The Internal Revenue Code (the "Code") limits the amount of
    non-life insurance losses that may offset life insurance company taxable
    income. The Code also imposes an "equity tax" on mutual life insurance
    companies which, in effect, imputes an additional tax to the Company based
    on a formula that calculates the difference between stock and mutual
    insurance companies' earnings. Income taxes include an estimate for changes
    in the total equity tax to be paid for current and prior years. Subsidiaries
    operating outside the United States are taxed under applicable foreign
    statutes.

    Deferred income taxes are generally recognized, based on enacted rates, when
    assets and liabilities have different values for financial statement and tax
    reporting purposes. A valuation allowance is recorded to reduce a deferred
    tax asset to that portion which management believes is more likely than not
    to be realized.

    NEW ACCOUNTING PRONOUNCEMENTS

    In June 1996, the Financial Accounting Standards Board ("FASB") issued the
    Statement of Financial Accounting Standards ("SFAS") No. 125, "Accounting
    for Transfers and Servicing of Financial Assets and Extinguishments of
    Liabilities" ("SFAS

    125"). The statement provides accounting and reporting standards for
    transfers and servicing of financial assets and extinguishments of
    liabilities and provides consistent standards for distinguishing transfers
    of financial assets that are sales from transfers that are secured
    borrowings. SFAS 125 became effective January 1, 1997 and is to be applied
    prospectively. Subsequent to June 1996, FASB issued SFAS No. 127 "Deferral
    of the Effective Date of Certain Provisions of SFAS 125" ("SFAS 127"). SFAS
    127 delays the implementation of SFAS 125 for one year for certain
    provisions, including repurchase agreements, dollar rolls, securities
    lending and similar transactions. The Company will delay implementation
    with respect to those affected provisions. Adoption of SFAS 125 has not and
    will not have a material impact on the Company's results of operations,
    financial condition and liquidity.

    In June of 1997, FASB issued SFAS No. 130, "Reporting Comprehensive Income,"
    which is effective for years beginning after December 15, 1997. This
    statement defines comprehensive income as "the change in equity of a
    business enterprise during a period from transactions and other events and
    circumstances from non-owner sources, excluding investments by owners and
    distributions to owners" and establishes standards for reporting and
    displaying comprehensive income and its components in financial statements.
    The statement requires that the Company classify items of other
    comprehensive income by their nature and display the accumulated balance of
    other comprehensive income separately from retained earnings in the equity
    section of the Statement of Financial Position. In addition,
    reclassification of financial statements for earlier periods must be
    provided for comparative purposes.

    RECLASSIFICATIONS

    Certain amounts in the prior years have been reclassified to conform to
    current year presentation.

   the right to call or prepay obligations

   Proceeds from the repayment of held to maturity fixed maturities during 1997,
   1996 and 1995 were $4,042 million, $4,268 million, and $3,767 million,
   respectively. Gross gains of $62 million, $78 million, and $27 million, and
   gross losses of $1 million, $7 million, and $0.2 million were realized on

</TABLE>

     The $60 million, $256 million and $32 million reduction of the mortgage
     loan allowance for losses in 1997, 1996 and 1995, respectively, is
     primarily attributable to the improved economic climate, changes in the
     nature and mix of borrowers and underlying collateral and a significant
     decrease in impaired loans consistent with a general decrease in the
     mortgage loan portfolio due to prepayments, sales and foreclosures.

5.   FUTURE POLICY BENEFITS AND OTHER POLICYHOLDERS' LIABILITIES (CONTINUED)

     For the above categories, premium deficiency reserves are established, if
     necessary, when the liability for future policy benefits plus the present
     value of expected future gross premiums are insufficient to provide for
     expected future policy benefits and expenses. A premium deficiency reserve
     has been recorded for the group single premium annuity business, which
     consists of limited-payment, long duration, traditional non-participating
     annuities. A liability of $1,645 million and $1,320 million is included in
     "Future policy benefits" with respect to this deficiency for the years
     ended December 31, 1997 and 1996, respectively.

     The changes in provision for claims and claim adjustment expenses related
     to prior years of $11 million, $(91) million and $141 million in 1997, 1996
     and 1995, respectively, are due to such factors as changes in claim cost
     trends in healthcare, an accelerated decline in indemnity health business,
     and lower than anticipated property and casualty unpaid claims and claim
     adjustment expenses.

     The other policyholders' liabilities presented above consist primarily of
     unpaid claim liabilities which include estimates for liabilities associated
     with reported claims and for incurred but not reported claims based, in
     part, on the Company's experience. Changes in the estimated cost to settle
     unpaid claims are charged or credited to the statement of operations
     periodically as the estimates are revised. Accident and health unpaid
     claims liabilities for 1997 and 1996 included above are discounted using
     interest rates ranging from 6.0% to 7.5%.

     (a) The rate shown for zero coupon notes, which do not bear interest,
     represents a level yield to maturity.

     Payment of interest and principal on the surplus notes of $686 million
     issued after 1993 may be made only with the prior approval of the
     Commissioner of Insurance of the State of New Jersey.

     In order to modify exposure to interest rate and currency exchange rate
     movements, the Company utilizes derivative instruments, primarily interest
     rate swaps, in conjunction with some of its debt issues. The effect of
     these derivative instruments is included in the calculation of the interest
     expense on the associated debt, and as a result, the effective interest
     rates on the debt may differ from the rates reflected in the tables above.
     Floating rates are determined by formulas and may be subject to certain
     minimum or maximum rates.

     Scheduled principal repayments of long-term debt as of December 31, 1997,
     are as follows: $357 million in 1998, $808 million in 1999, $260 million in
     2000, $32 million in 2001, $1,814 million in 2002 and $1,379 million
     thereafter.

     At December 31, 1997, the Company had $8,257 million in lines of credit
     from numerous financial institutions of which $5,160 million were unused.
     These lines of credit generally have terms ranging from 1 to 5 years.

7.   EMPLOYEE BENEFIT PLANS

     PENSION PLANS

     The Company has one funded non-contributory defined benefit pension plan,
     which covers substantially all of its employees. The Company also has
     several non-contributory non-funded defined benefit plans covering certain
     executives. Benefits are generally based on career average earnings and
     credited length of service. The Company's funding policy is to contribute
     annually an amount necessary to satisfy the Internal Revenue Service
     contribution guidelines.

     Prepaid and accrued pension costs are included in "Other assets" and "Other
     liabilities," respectively, in the Company's consolidated statements of
     financial position. The status of these plans as of September 30, adjusted
     for fourth quarter activity related to funding activity and contractual
     termination benefits is summarized below:

     Plan assets consist primarily of equity securities, bonds, real estate and
     short-term investments, of which $6,022 million and $5,668 million are
     included in Separate Account assets and liabilities at December 31, 1997
     and 1996, respectively.

     Effective December 31, 1996, The Prudential Securities Incorporated Cash
     Balance Plan (the "PSI Plan") was merged into The Retirement System for
     United States Employees and Special Agents of The Prudential Insurance
     Company of America (the "Prudential Plan"). The name of the merged plan is
     The Prudential Merged Retirement Plan ("Merged Retirement Plan"). All of
     the assets of the Merged Retirement Plan are available to pay benefits to
     participants and their beneficiaries who are covered by the Merged
     Retirement Plan. The merger of the plans had no effect on the December 31,
     1996 consolidated financial position or results of operations.

     During 1996, the Prudential Plan was amended to provide cost of living
     adjustments for retirees. The effect of this plan amendment increased
     benefit obligations and unrecognized prior service cost by $170 million at
     September 30, 1996. In addition, the Prudential Plan was amended to provide
     contractual termination benefits to certain plan participants who were
     notified between September 15, 1996 and December 31, 1997 that their
     employment had been terminated. During 1997, the Prudential Retirement Plan
     Document, a component of the Merged Retirement Plan was amended to extend
     the contractual termination benefits to December 31, 1998. Costs related to
     these amendments are reflected below in contractual termination benefits.

     OTHER POSTRETIREMENT BENEFITS

     The Company provides certain life insurance and health care benefits for
     its retired employees, their beneficiaries and covered dependents.
     Substantially all of the Company's employees may become eligible to receive
     benefits if they retire after age 55 with at least 10 years of service, or
     under circumstances after age 50 with at least 20 years of continuous
     service.

     The Company has elected to amortize its transition obligation over 20
     years. Post-retirement benefits are funded as considered necessary by
     Company management. The Company's funding of its postretirement benefit
     obligations totaled $43 million, $38 million and $94 million in 1997, 1996
     and 1995, respectively.

     In 1995 the Company modified the restrictions on certain post-retirement
     plan assets to allow these assets to be used for benefits related to both
     active and retired employees. Formerly, these benefits were available only
     for retired employees. In connection with this modification, the Company
     transferred $120 million from one of these plans in 1995. Of the $120
     million transferred, $45 million went to Union Post-Retirement Benefits and
     $75 million went to Union Medical Benefits.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


8.   INCOME TAXES (CONTINUED)

     Management believes that based on its historical pattern of taxable income,
     the Company will produce sufficient income in the future to realize its net
     deferred tax asset after valuation allowance. Adjustments to the valuation
     allowance will be made if there is a change in management's assessment of
     the amount of the deferred tax asset that is realizable. At December 31,
     1997, the Company had state non-life operating loss carryforwards for tax
     purposes approximating $800 million.

     The Internal Revenue Service (the "Service") has completed an examination
     of the consolidated federal income tax return through 1989. The Service has
     examined the years 1990 through 1992. Discussions are being held with the
     Service with respect to proposed adjustments, however, management believes
     there are adequate defenses against, or sufficient reserves to provide for,
     such adjustments. The Service has begun their examination of the years 1993
     through 1995.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

9.   EQUITY (CONTINUED)

     The New York State Insurance Department ("Department") recognizes only
     statutory accounting for determining and reporting the financial condition
     of an insurance company, for determining its solvency under the New York
     Insurance Law and for determining whether its financial condition warrants
     the payment of a dividend to its policyholders. No consideration is given
     by the Department to financial statements prepared in accordance with GAAP
     in making such determinations.

10.  OPERATING LEASES

     The Company and its subsidiaries occupy leased office space in many
     locations under various long-term leases and have entered into numerous
     leases covering the long-term use of computers and other equipment. At
     December 31, 1997, future minimum lease payments under non-cancelable
     operating leases are estimated as follows:

                                                   (IN MILLIONS)

                                                   ===========



     Rental expense incurred for the years ended December 31, 1997 and 1996 was
     approximately $352 million and $343 million, respectively.


11.  DIVESTITURES

     In October 1995, the Company completed the sale of its reinsurance segment,
     Prudential Reinsurance Holdings, Inc., through an initial public offering
     of common stock. As a result of the sale, an after-tax loss of $297 million
     was recorded in 1995.

     On January 26, 1996, the Company entered into a definitive agreement to
     sell substantially all the assets of Prudential Home Mortgage Company, Inc.
     It has also liquidated certain mortgage-backed securities and extended
     warehouse losses, asset write downs, and other costs directly related to
     the planned sale. The Company recorded an after-tax loss in 1995 of $98
     million which includes operating gains and losses, asset write downs and
     other costs directly related with the planned sale. The net assets of the
     mortgage banking segment at December 31, 1995 was $78 million, comprised of
     $4,293 million in assets and $4,215 million in liabilities.

     On July 31, 1996, the Company sold a substantial portion of its Canadian
     Branch business to the London Life Insurance Company ("London Life"). This
     transaction was structured as a reinsurance transaction whereby London Life
     assumed total liabilities of the Canadian Branch equal to $3,291 million as
     well as a related amount of assets equal to $3,205 million. This transfer
     resulted in a reduction of policy liabilities of $3,257 million and a
     corresponding reduction in invested assets. The Company recognized an
     after-tax gain in 1996 of $116 million as a result of this transaction,
     recorded in "Realized investment gains, net."

12.  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The fair values presented below have been determined using available
     information and valuation methodologies. Considerable judgment is applied
     in interpreting data to develop the estimates of fair value. Accordingly,
     such estimates presented may not be realized in a current market exchange.
     The use of different market assumptions and/or estimation methodologies
     could have a material effect on the estimated fair values. The following
     methods and assumptions were used in calculating the fair values (for all
     other financial instruments presented in the table, the carrying value
     approximates fair value).

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

12.  FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)

     FIXED MATURITIES AND EQUITY SECURITIES

     Fair values for fixed maturities and equity securities, other than private
     placement securities, are based on quoted market prices or estimates from
     independent pricing services. Fair values for private placement securities
     are estimated using a discounted cash flow model which considers the
     current market spreads between the U.S. Treasury yield curve and corporate
     bond yield curve, adjusted for the type of issue, its current credit
     quality and its remaining average life. The estimated fair value of certain
     non-performing private placement securities is based on amounts estimated
     by management.

     MORTGAGE LOANS ON REAL ESTATE

     The fair value of the mortgage loan portfolio is primarily based upon the
     present value of the scheduled future cash flows discounted at the
     appropriate U.S. Treasury rate, adjusted for the current market spread for
     a similar quality mortgage. For certain non-performing and other loans, the
     fair value is based upon the present value of expected future cash flows
     discounted at the appropriate U.S. Treasury rate adjusted for current
     market spread for a similar quality mortgage.

     POLICY LOANS

     The estimated fair value of policy loans is calculated using a discounted
     cash flow model based upon current U.S. Treasury rates and historical loan
     repayments.

     DERIVATIVE FINANCIAL INSTRUMENTS

     The fair value of swap agreements is estimated based on the present value
     of future cash flows under the agreements discounted at the applicable zero
     coupon U.S. Treasury rate and swap spread. The fair value of forwards,
     futures and options is estimated based on market quotes for a transaction
     with similar terms. The fair value of loan commitments is derived by
     comparing the contractual stream of fees with such fee streams adjusted to
     reflect current market rates that would be applicable to instruments of
     similar type, maturity, and credit standing.

     POLICYHOLDERS' ACCOUNT BALANCES

     Fair values of policyholders' account balances are estimated using
     discounted projected cash flows, based on interest rates being offered for
     similar contracts, with maturities consistent with those remaining for the
     contracts being valued.

     DEBT

     The estimated fair value of short-term and long-term debt is derived by
     using discount rates based on the borrowing rates currently available to
     the Company for debt with similar terms and remaining maturities.

     DERIVATIVE FINANCIAL INSTRUMENTS

     The tables below summarize the Company's outstanding positions by
     derivative instrument types as of December 31, 1997 and 1996. The amounts
     presented are classified as either trading or other than trading, based on
     management's intent at the time of contract inception and throughout the
     life of the contract. The table includes the estimated fair values of
     outstanding derivative positions only and does not include the changes in
     fair values of associated financial and non-financial assets and
     liabilities, which generally offset derivative notional amounts. The fair
     value amounts presented also do not reflect the netting of amounts pursuant
     to right of setoff, qualifying master netting agreements with
     counterparties or collateral arrangements.

     CREDIT RISK

     The current credit exposure of the Company's derivative contracts is
     limited to the fair value at the reporting date. Credit risk is managed by
     entering into transactions with creditworthy counterparties and obtaining
     collateral where appropriate and customary. The Company also attempts to
     minimize its exposure to credit risk through the use of various credit
     monitoring techniques. Approximately 95% of the net credit exposure for the
     Company from derivative contracts is with investment-grade counterparties.

     Net trading revenues for the years ended December 31, 1997, 1996 and 1995
     relating to forwards, futures and swaps were $54 million, $37 million, $(8)
     million; $42 million, $32 million, $(11) million; and $110 million, $42
     million, $3 million respectively. Net trading revenues for options were not
     material. Average fair values for trading derivatives in an asset position
     during the years ended December 31, 1997 and 1996 were $1,015 million and
     $881 million, respectively, and for derivatives in a liability position
     were $1,166 million and $1,038 million, respectively. Of those derivatives
     held for trading purposes at December 31, 1997, 52% of the notional amount
     consisted of interest rate derivatives, 40% consisted of foreign currency
     derivatives, and 8% consisted of equity and commodity derivatives. Of those
     derivatives held for purposes other than trading at December 31, 1997, 72%
     of notional consisted of interest rate derivatives and 28% consisted of
     foreign currency derivatives.

13.  DERIVATIVE AND OFF-BALANCE SHEET CREDIT-RELATED INSTRUMENTS (CONTINUED)

     OFF-BALANCE SHEET CREDIT-RELATED INSTRUMENTS

     During the normal course of its business, the Company utilizes financial
     instruments with off-balance sheet credit risk such as commitments,
     financial guarantees, loans sold with recourse and letters of credit.
     Commitments include commitments to purchase and sell mortgage loans, the
     unfunded portion of commitments to fund investments in private placement
     securities, and unused credit card and home equity lines. The Company also
     provides financial guarantees incidental to other transactions and letters
     of credit that guarantee the performance of customers to third parties.
     These credit-related financial instruments have off-balance sheet credit
     risk because only their origination fees, if any, and accruals for probable
     losses, if any, are recognized until the obligation under the instrument is
     fulfilled or expires. These instruments can extend for several years and
     expirations are not concentrated in any period. The Company seeks to
     control credit risk associated with these instruments by limiting credit,
     maintaining collateral where customary and appropriate, and performing
     other monitoring procedures.

     The fair value of asset positions in these instruments, which represents
     the Company's current exposure to credit loss from other parties'
     non-performance, was $1,014 million and $936 million at December 31, 1997
     and 1996, respectively.

14.  CONTINGENCIES AND LITIGATION

     FINANCIAL GUARANTEE AGREEMENT

     In connection with the sale in 1995 of its wholly-owned subsidiary
     Prudential Reinsurance Company ("Pru Re"), the Company's subsidiary,
     Gibraltar Casualty Insurance Company ("Gibraltar") entered into a stop-loss
     reinsurance agreement with Pru Re whereby Gibraltar has reinsured up to
     $375 million of the first $400 million of aggregate adverse loss
     development on reserves recorded by Pru Re at June 30, 1995. Gibraltar also
     has entered into several quota share reinsurance arrangements with Pru Re
     whereby certain medical malpractice, direct insurance and casualty
     reinsurance pool risks previously underwritten by Pru Re prior to June 30,
     1995 were ceded to Gibraltar. The Company has guaranteed Gibraltar's
     obligations arising under each of these contracts subject to a limit of
     $375 million for the stop-loss agreement and $400 million for the other
     agreements. Through December 31, 1997, Gibraltar has incurred $285 million
     in losses under the stop-loss agreement, including $45 million in 1997.
     Gibraltar has paid $165 million to Pru Re under the stop-loss agreement.
     The Company has not been required to fund losses arising under the other
     arrangements.

     ENVIRONMENTAL AND ASBESTOS-RELATED CLAIMS

     Certain of the Company's subsidiaries received claims under expired
     contracts which assert alleged injuries and/or damages relating to or
     resulting from toxic torts, toxic waste and other hazardous substances. The
     liabilities for such claims cannot be estimated by traditional reserving
     techniques. As a result of judicial decisions and legislative actions, the
     coverage afforded under these contracts may be expanded beyond their
     original terms. Extensive litigation between insurers and insureds over
     these issues continues and the outcome is not predictable. In establishing
     the liability for unpaid claims for these losses, management considered the
     available information. However, given the expansion of coverage and
     liability by the courts and legislatures in the past, and potential for
     other unfavorable trends in the future, the ultimate cost of these claims
     could increase from the levels currently established.

     MANAGED CARE REIMBURSEMENT

     In 1997, the Company continued to review its obligations under certain
     managed care arrangements for possible failure to comply with contractual
     and regulatory requirements. The estimated cost to the Company for these
     reimbursements increased by $115 million in 1997, bringing the total
     provision to $265 million. As of December 31, 1997, $163 million has been
     paid or credited to customers. It is the opinion of management that the
     remaining reserves of $102 million at December 31, 1997 represent a
     reasonable estimate of remaining reimbursements to customers and other
     related costs.

     LITIGATION

     Various lawsuits against the Company have arisen in the course of the
     Company's business. In certain of these matters, large and/or indeterminate
     amounts are sought.

     Three putative class actions and approximately 677 individual actions were
     pending against the Company in the United States as of January 31, 1998
     brought on behalf of those persons who purchased life insurance policies
     allegedly because of deceptive sales practices engaged in by the Company
     and its insurance agents in violation of state and federal laws. The
     Company anticipates additional suits may be filed by individuals who opted
     out of the class action settlement described below. The sales practices
     alleged to have occurred are contrary to Company policy. Some of

14.  CONTINGENCIES AND LITIGATION (CONTINUED)

     these cases seek substantial damages while others seek unspecified
     compensatory, punitive and treble damages. The Company intends to defend
     these cases vigorously.

     A Multi-State Life Insurance Task Force (the "Task Force"), comprised of
     insurance regulators from 29 states and the District of Columbia, was
     formed in April 1995 to conduct a review of sales and marketing practices
     throughout the life insurance industry. As the largest life insurance
     company in the United States, the Company was the initial focus of the Task
     Force examination. On July 9, 1996, the Task Force released its report on
     the Company's activities. The Task Force found that some sales of life
     insurance policies by the Company had been improper. Based on the findings,
     the Task Force recommended, and the Company agreed to, a series of fines
     allocated to all 50 states and the District of Columbia. In addition, the
     Task Force recommended a remediation program pursuant to which the Company
     would offer relief to the policyowners who were misled when they purchased
     permanent life insurance policies in the United States from 1982 to 1995.

     On October 28, 1996, the Company entered into a Stipulation of Settlement
     with attorneys for the plaintiffs in the consolidated class action lawsuit
     pending in a Multi-District Litigation proceeding in the federal court in
     New Jersey. The class action suit involved alleged improprieties in
     connection with the Company's sale, servicing and operation of permanent
     life insurance policies from 1982 through 1995. Pursuant to the settlement,
     the Company agreed to provide certain enhancements and changes to the
     remediation program previously accepted by the Task Force, including some
     additional remedies. In addition, the Company agreed that it would incur a
     minimum cost of $410 million in providing remedies to policyowners under
     the program and, in specified circumstances, agreed to make certain other
     payments and guarantees. Under the terms of the settlement, the Company
     agreed to a minimum average cost per remedy of $2,364 for up to 330,000
     claims remedied and also agreed to provide additional compensation to be
     determined by formula that will range in aggregate amount from $50 million
     to $300 million depending on the total number of claims remedied. At the
     end of the remediation program's claim evaluation process, the Court will
     determine how the additional compensation will be distributed.

     The terms of the remediation program described above were enhanced again in
     February 1997 pursuant to agreements reached with several states that had
     not previously accepted the terms of the program. These changes were
     incorporated as amendments to the above-described Stipulation of Settlement
     and related settlement documents, and the amended Stipulation of Settlement
     was approved as fair to class members by the United States District Court
     for the District of New Jersey in March 1997. By that point in time, the
     Company had entered into agreements with all 50 states and the District of
     Columbia pursuant to which each jurisdiction had accepted the remediation
     plan and the Company had agreed to pay approximately $65 million in fines,
     penalties and related payments.

     The decision of the U.S. District Court to certify a class in the
     above-described litigation for settlement purposes only and to approve the
     class action settlement as described in the amended Stipulation of
     Settlement is presently on appeal to the U.S. Court of Appeals for the
     Third Circuit. The appellants claim that the District Court erred in
     certifying a class and in finding that the terms of the settlement are fair
     to the class.

     Pursuant to the state agreements and the amended Stipulation of Settlement,
     as approved by the U.S. District Court, the Company initiated its
     remediation program in 1997. The Company mailed packages and provided broad
     class notice to the owners of approximately 10.7 million policies eligible
     to participate in the remediation program, informing them of their rights.
     Owners of approximately 21,800 policies elected to be excluded from the
     class action settlement. Of those eligible to participate in the
     settlement, policyowners who believed they were misled were invited to file
     a claim through an Alternative Dispute Resolution ("ADR") process. The ADR
     process was established to enable the company to discharge its liability to
     the affected policyowners. Policyowners who did not wish to file a claim in
     the ADR process were permitted to choose from options available under Basic
     Claim Relief, such as preferred rate premium loans, or annuities, mutual
     fund shares or life insurance policies that the Company will enhance.

     The owners of approximately 1.16 million policies responded to these
     notices by indicating an intent to file an ADR claim. All policyholders who
     responded were provided an ADR claim form for completion and submission.
     Approximately 635,000 claim forms were completed and returned as of January
     31, 1998. Management does not believe the number of ADR claims that will be
     completed and returned will increase significantly. In addition, the owners
     of approximately 510,000 policies indicated an interest in a Basic Claim
     Relief remedy. The ADR process requires that individual claim files be

                   THE PRUDENTIAL INSURANCE COMPANY OF AMERICA

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

14.  CONTINGENCIES AND LITIGATION (CONTINUED)

     In 1996, the Company recorded in its Statement of Operations, the minimum
     cost of $410 million as agreed to in the settlement. Management had no
     better information available at that time upon which to make a reasonable
     estimate of losses. Management now has additional information which allows
     for computation of a reasonable estimate of losses associated with ADR
     claims. Based on this additional information, in 1997, management had
     increased the estimated liability for the cost of remedying policyholder
     claims in the ADR process by $1.64 billion before taxes to approximately
     $2.05 billion before taxes of which $1.80 billion has been funded in a
     settlement trust as described in Note 3. While management believes these
     are reasonable estimates based on information currently available, the
     ultimate amount of the total cost of remedied policyholder claims is
     dependent on complex and varying factors, including actual claims by
     eligible policyholders, the relief options chosen and the dollar value of
     those options. There are also additional elements of the ADR process which
     cannot be fully evaluated at this time (e.g., claims which may be
     successfully appealed) which could increase this estimate.

     Litigation is subject to many uncertainties, and given the complexity and
     scope of these suits, their outcome cannot be predicted. It is also not
     possible to predict the likely results of any regulatory inquiries or their
     effect on litigation which might be initiated in response to widespread
     media coverage of these matters. Accordingly, management is unable to make
     a meaningful estimate of the amount or range of loss that could result from
     an unfavorable outcome of all pending litigation and the regulatory
     inquiries. It is possible that the results of operations or the cash flow
     of the Company, in particular quarterly or annual periods, could be
     materially affected by an ultimate unfavorable outcome of certain pending
     litigation and regulatory matters. Management believes, however, that the
     ultimate outcome of all pending litigation and regulatory matters referred
     to above should not have a material adverse effect on the Company's
     financial position, after consideration of applicable reserves.

     The Company and a number of other insurers ("the Consortium") entered into
     a Reinsurance and Participation Agreement (the "Agreement") with MBL Life
     Assurance Corporation ("MBLLAC") and others, under which the Company and
     the other insurers agreed to reinsure certain payments to be made to
     contract holders by MBLLAC in connection with the plan of rehabilitation of
     Mutual Benefit Life Insurance Company. Under the agreement, the Consortium,
     subject to certain terms and conditions, will indemnify MBLLAC for the
     ultimate net loss sustained by MBLLAC on each contract subject to the
     Agreement. The ultimate net loss represents the amount by which the
     aggregate required payments exceed the fair market value of the assets
     supporting the covered contracts at the time such payments are due. The
     Company's share of any net loss is 30.55%. The Company has determined that
     it does not expect to make any payments to MBLLAC under the agreement. The
     Company concluded this after testing a wide range of potentially adverse
     scenarios during the rehabilitation period for MBLLAC.

15.  SUBSEQUENT EVENTS

     On February 10, 1998, the Company's Board of Directors authorized
     management to take the preliminary steps necessary to allow the Company to
     demutualize and become a publicly-traded company. The Company has begun
     discussions with the New Jersey Department of Banking and Insurance,
     leaders in the New Jersey State Legislature, as well as other key
     regulatory agencies around the country. The New Jersey State Legislature
     must first pass a law permitting demutualization. The New Jersey Department
     of Banking and Insurance, the Company's Board and a majority of
     participating policyholders must ultimately approve the Company's plan for
     demutualization.

ITEM 25. PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH REGISTRANT

        The Prudential is a mutual life insurance company incorporated under the
        laws of the State of New Jersey. The subsidiaries of The Prudential are
        set forth on the Organization Chart on the following pages.

        All of the shares of Prudential's Gibraltar Fund are held by three
        separate accounts of The Prudential Insurance Company of America:
        Prudential's Investment Plan Account, Prudential's Annuity Plan Account
        and Prudential's Annuity Plan Account-2. The Prudential also holds
        directly and in four of its other separate accounts shares of The
        Prudential Series Fund, Inc., a Maryland corporation. The balance of the
        shares of The Prudential Series Fund, Inc. are held in separate accounts
        of Pruco Life Insurance Company, a direct wholly-owned subsidiary of The
        Prudential, and Pruco Life Insurance Company of New Jersey, an indirect
        wholly-owned subsidiary of The Prudential. All of the separate accounts
        referred to above are unit investment trusts registered under the
        Investment Company Act of 1940. Prudential's Gibraltar Fund and The
        Prudential Series Fund, Inc. are registered as open-end, diversified
        management investment companies under the Investment Company Act of
        1940. The shares of the investment companies are voted in accordance
        with the instructions of persons having an interest in the unit
        investment trusts, and The Prudential, Pruco Life Insurance Company and
        Pruco Life Insurance Company of New Jersey will vote the shares they
        hold directly in the same manner that they vote the shares that they
        hold in their separate accounts.

        Registrant may also be deemed to be under common control with The
        Prudential Variable Contract Account-2, The Prudential Variable Contract
        Account-10 and The Prudential Variable Contract Account-11, separate

ITEM 27.    INDEMNIFICATION OF DIRECTORS AND OFFICERS     
                
            The Registrant, in conjunction with certain affiliates, maintains
            insurance on behalf of any person who is or was a trustee, director,
            officer, employee, or agent of the Registrant, or who is or was
            serving at the request of the Registrant as a trustee, director,
            officer, employee or agent of such other affiliated trust or
            corporation, against any liability asserted against and incurred by
            him or her arising out of his or her position with such trust or
            corporation.    
                
            New Jersey, being the state of organization of Prudential Insurance
            Company of America ("Prudential"), permits entities organized under
            its jurisdiction to indemnify directors and officers with certain
            limitations. The relevant provisions of New Jersey law permitting
            indemnification can be found in Section 14A:3-5 of the New Jersey
            Statutes Annotated. The text of Prudential's By-Law 27, which
            relates to indemnification of officers and directors, is
            incorporated by reference to Exhibit (8)(ii) of Post-Effective
            Amendment No. 26 to Form N-3, Registration No. 2-76580, filed May 1,
            1995, on behalf of The Prudential Variable Contract Account-10.    
         
            Insofar as indemnification for liabilities arising under the
            Securities Act of 1933 may be permitted to directors, officers and
            controlling persons of the Registrant pursuant to the foregoing
            provisions or otherwise, the Registrant has been advised that in the
            opinion of the Securities and Exchange Commission such
            indemnification is against public policy as expressed in the Act and
            is, therefore, unenforceable. In the event that a claim for
            indemnification against such liabilities (other than the payment by
            the Registrant of expenses incurred or paid by a director, officer
            or controlling person of the Registrant in the successful defense of
            any action, suit or proceeding) is asserted by such director,
            officer or controlling person in connection with the securities
            being registered, the Registrant will, unless in the opinion of its
            counsel the matter has been settled by controlling precedent, submit
            to a court of appropriate jurisdiction the question whether such
            indemnification by it is against public policy as expressed in the
            Act and will be governed by the final adjudication of such issue.

ITEM 28.    BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISOR
             
            Prudential is involved in insurance, reinsurance, securities,

        directly and in four of its other separate accounts shares of The
        Prudential Series Fund, Inc., a Maryland corporation. The balance of the
        shares of The Prudential Series Fund, Inc. are held in separate accounts
        of Pruco Life Insurance Company, a direct wholly-owned subsidiary of The

        investment trusts, and The Prudential, Pruco Life Insurance Company and
        Pruco Life Insurance Company of New Jersey will vote the shares they
        hold directly in the same manner that they vote the shares that they

ITEM 27.    INDEMNIFICATION OF DIRECTORS AND OFFICERS     
                
            The Registrant, in conjunction with certain affiliates, maintains
            insurance on behalf of any person who is or was a trustee, director,
            officer, employee, or agent of the Registrant, or who is or was
            serving at the request of the Registrant as a trustee, director,
            officer, employee or agent of such other affiliated trust or
            corporation, against any liability asserted against and incurred by
            him or her arising out of his or her position with such trust or
            corporation.    
                
            New Jersey, being the state of organization of Prudential Insurance
            Company of America ("Prudential"), permits entities organized under
            its jurisdiction to indemnify directors and officers with certain
            limitations. The relevant provisions of New Jersey law permitting
            indemnification can be found in Section 14A:3-5 of the New Jersey
            Statutes Annotated. The text of Prudential's By-Law 27, which
            relates to indemnification of officers and directors, is
            incorporated by reference to Exhibit (8)(ii) of Post-Effective
            Amendment No. 26 to Form N-3, Registration No. 2-76580, filed May 1,
            1995, on behalf of The Prudential Variable Contract Account-10.    
         
            Insofar as indemnification for liabilities arising under the
            Securities Act of 1933 may be permitted to directors, officers and
            controlling persons of the Registrant pursuant to the foregoing
            provisions or otherwise, the Registrant has been advised that in the
            opinion of the Securities and Exchange Commission such
            indemnification is against public policy as expressed in the Act and
            is, therefore, unenforceable. In the event that a claim for
            indemnification against such liabilities (other than the payment by
            the Registrant of expenses incurred or paid by a director, officer
            or controlling person of the Registrant in the successful defense of
            any action, suit or proceeding) is asserted by such director,
            officer or controlling person in connection with the securities
            being registered, the Registrant will, unless in the opinion of its
            counsel the matter has been settled by controlling precedent, submit
            to a court of appropriate jurisdiction the question whether such
            indemnification by it is against public policy as expressed in the
            Act and will be governed by the final adjudication of such issue.

ITEM 28.    BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISOR
             
            Prudential is involved in insurance, reinsurance, securities,
            pension services, real estate and banking.

            who are engaged directly or indirectly in activities relating to the
            registrant have no other business, profession, vocation, or
            employment of a substantial nature, and have not had such other
            connections during the past two years.
