"We continue to believe that diversification and a long-term perspective are the
keys to a successful investment strategy and can help you receive more
consistent returns over time."

Dear Contract Owner:

This Annual Report presents the investment performance of the portfolios that
underlie your Pruco Life Variable Universal Life insurance contract.

Last year, the stock market registered double-digit returns for an unprecedented
fourth consecutive year. However, the global financial crisis drove many
investors to focus on only the largest and most marketable securities. As a
result, companies with the most predictable earnings and largest market
capitalization generated the lion's share of the stock market gains while
small-company and value stocks lagged dramatically.

This "flight to quality" also drove the yield on the 30-year Treasury bond to
4.71%, its lowest level since April 1967, which made virtually all other debt
securities very unattractive.

The turning point for the financial markets came in the fall when a round of
interest rate cuts by central banks around the world, including the U.S. Federal
Reserve, fueled investor confidence and prompted investors to move money back
into riskier investments with higher potential total returns. (Total return is
interest or dividends plus capital appreciation.) Forecasts that there would be
a huge rise in on-line business also helped the bull market regain its footing
by sparking a fourth quarter rally in technology stocks.

How Did the Portfolios Perform?

Consistent with the market, our large-capitalization growth stock
portfolio-Prudential Jennison-posted an unusually high return of 37.5% for the
year. On the other hand, our value-oriented Equity and Equity Income portfolios
lagged the growth-oriented average, with the mid-cap value-oriented Equity
Income actually down a disappointing 2.4% for the year. Many of our other
portfolios finished with solid results, including our Global portfolio.

Keep the Markets in Perspective

As we begin the new year, the U.S. stock market is at historic highs in terms of
the price placed on companies' earning powers. We expect markets eventually to
bring prices in line with earnings performance. We have already begun to see
fixed-income investors shift money back into investment-grade and high-yield
corporate bonds, as well as into emerging market, mortgage-backed and
asset-backed securities. Furthermore, growth and value styles of investing tend
to alternate in superior performance, making it often unwise to chase last
year's market winners.

We continue to believe that diversification and a long-term perspective are the
keys to a successful investment strategy and can help you receive more
consistent returns over time. It is also a good practice to rebalance your
holdings when necessary to keep your asset allocation consistent with your
objectives and risk tolerance.

It's Long-Term Performance That Counts.

Although this Report focuses primarily on one-year returns, remember that it's
long-term performance that counts. Review your Portfolio's 1998 performance, but
also examine its longer-term record as well. You'll note that over the past
three, five and 10 years, many of the Prudential Series Fund Portfolios have
delivered excellent returns, both on an absolute basis and in comparison with
funds having similar objectives as reported by Lipper, Inc.

Since most people buy variable life products to finance long-term goals, our
objective for these Portfolios is to achieve above-average investment
performance over time. Therefore, when you consider how to allocate either new
or existing assets among our available options, we encourage you to think about
your time horizon and risk tolerance. As always, remember that past performance
is not necessarily indicative of future results.

Your Prudential professional would be happy to help you review and structure a
program to meet your long-term financial needs.

All of us at Prudential thank you for your business and look forward to helping
you plan for your future financial security.

Important Note

The rates of return quoted on the following pages reflect the deduction of
investment management fees and investment-related expenses, but not product
charges. They reflect the reinvestment of dividend and capital gains
distributions. They are not an estimate or a guarantee of future performance.

Contract unit values increase or decrease based on the performance of the
Portfolio and, when redeemed, may be worth more or less than their original
cost. Changes in contract values depend not only on the investment performance
of the Portfolio but also on the insurance and administrative charges,
applicable sales charges, and the mortality and expense risk charge applicable
under the contract. These contract charges effectively reduce the dollar amount
of any net gains and increase the dollar amount of any net losses.

Your Prudential Representative/Pruco Securities Registered Representative can
provide you with actual rates of return for your type of variable life insurance
or annuity contract and show you a personalized illustration of how insurance
charges affect the returns you experience.

1998 Market Commentary

Market Overview

o     The Asian economic and financial crises, which culminated in the Russian
      default, drove down the price of stocks throughout that region and then
      throughout the world in the third quarter.

o     Despite this volatility, most stock markets around the world posted
      double-digit gains for the year. Interest rate cuts by the U.S. Federal
      Reserve in September, October and November restored investor-confidence in
      the markets.

o     However, the performance of the average stock was below historical levels.
      In the U.S., most of the gains were driven by the largest stocks with the
      strongest franchises. Substantial performance disparities developed
      between large-capitalization companies and small-capitalization companies
      and between value and growth stocks.

o     The prospect that the Internet will transform society led to an almost
      unbelievable speculation in Internet-related stocks.

o     Investor uncertainty also manifested itself in the bond markets. Pursuit
      of the safest government bonds resulted in a significant rise in the
      yields of riskier bonds.

U.S. Stocks

Diverging Markets

Normally, the way to make money is to buy low and sell high. But looking at last
year's performance of stocks and bonds, it appears that the strategy that worked
best in 1998 was "momentum investing"--buying more of the most popular, most
expensive securities. Companies with the most predictable earnings and largest
market capitalization, which already were expensive at the beginning of 1998,
generated most of the year's stock market gains while small-company and value
stocks lagged dramatically.

Why did investors decide to buy high? The trouble began when the government of
Thailand devalued the baht in 1997. The currencies of several neighboring
countries also weakened and investors grew increasingly concerned about the
impact of an Asian economic slowdown.

This prompted many investors to focus on a few large, well-known companies,
which were expected to have more predictable earnings and marketable stocks.
When the Russian turmoil erupted last August, the focus on security intensified.

Since investors were willing to pay a premium for these well-known companies,
they boosted the return of these few firms above all others. Conversely,
small-company stocks, which generally are more vulnerable to negative financial
and economic news than large-company stocks, had a sharp price-drop in 1998.

This chart compares the 12-month return as of 12/31/98 for various categories of
investments with the average annual total return over 20 years for the same
investment. As you can see, stock and bond market returns can vary considerably
from year to year. Unlike stocks, bonds generally offer a fixed rate of return
and principal if held to maturity. An investment's past performance should never
be used to predict future results. There are different risks associated with
each investment sector, which should be carefully considered before investing.

In addition, value stocks--those that are inexpensive in terms of price-to-cash
flow, earnings and book value--also lagged large growth stocks dramatically.
This divergence in the market is reflected in the year-end returns of the major
equity indexes.

The Standard & Poor's 500 Composite Stock Price Index (the S&P 500 Index), which
represents the broad market to many investors, plunged in the third quarter but
ended 1998 with a total return of 28.6%. The stocks of companies with the
largest capitalization, measured by the Russell Top 200 Index (published by the
Frank Russell Company), gained a substantial 33.4% over the year.

However, the small-cap Russell 2000 Index actually fell by 2.6%. (Market
capitalization, frequently referred to as market cap or market value, is the
price that the stock market puts on an entire enterprise. It is calculated by
multiplying the current market price by the number of shares outstanding.)

As for the performances of growth and value stocks in the S&P 500, the S&P/Barra
Growth Index returned 42.1% for the year, versus the S&P/Barra Value Index, up
only 14.7%--an unusually wide 27-percentage-point difference.

In many cases, however, the earnings of the most popular companies did not rise
as much as their share prices. Investors paid more and more for each dollar of
these firms' profits in 1998. Many of the market leaders' stocks reached prices
60 to 70 times their annual earnings, compared with historical average
price-to-earnings (P/E) ratios of less than 20 times earnings.

1998 Winners and Losers

Technology Stocks Big Winners in 1998

The Technology sector, driven by new low-cost computers and the prospect that
Internet commerce will transform the way we do business, led the market in 1998
with a 67.4% growth. Dell Computer was a large contributor to the sector's
performance, up 249%. Software giants Microsoft and Apple were other major
contributors, rising 118% and 212%, respectively. The return of co-founder Steve
Jobs and the introduction of new low-priced iMac computers helped Apple come
back after languishing among the worst performers on the S&P 500 Index just one
year ago. It was the second-best performing stock in the Index. EMC Corp., the
world's largest maker of data-storage devices, claimed the #3 spot on the "S&P
500 Index Top 10" list, up 210% for the year. Inspired by expectations more than
by current earnings, the prices of companies of Internet-related stocks shot up
to unprecedented levels.

Consumer Cyclicals Finished Second

The Consumer Cyclicals sector came in a distant second for the year, but still
averaged an impressive 45.0% gain. Gap Inc. was the best name in the sector by
far, up 138%. Gap was the 10th best-performing company in the S&P 500 Index in
1998 as its line of khaki pants and casual clothes rode the trend toward less
formal work attire. Lowes Corp., up 115%, Home Depot, up 108%, and Wal-Mart, up
108%, were the other companies in the sector that doubled their prices for the
year.

1998 Market Commentary continued

Industrials Lagged

In our view, the Industrial sector of the U.S. economy suffered a brief
recession in mid 1998, due to the consequences of Asia's economic contraction.
The Far East is a major user of industrial products, such as machinery and
metals. Overbuilding and the declining cost of production in that region were
largely responsible for the sector's poor showing in the stock market. Within
the industrial sector of the S&P 500, machinery and nonferrous metals companies
were among the worst performers, losing 20% and 28%, respectively. Stronger
performances by office equipment and supplies companies and commercial services
helped the sector as a whole return just under 13%.

Energy Demand Was Low

The Energy sector, plagued by low demand throughout 1998 and a steep decline in
oil prices toward the end of the year, eked out a return of only 0.9%. Rowan,
down 68%, was among the worst performers in the sector. This oil service company
suffered as major oil producers reduced exploration and drilling operations and
crude oil prices plunged to 12-year lows. Baker Hughes, the fourth-largest U.S.
oil field services and equipment company, was down 59% for the year. It has
announced plans to eliminate 2,000 jobs.


The World

A Tumultuous Twelve Months

In 1998, the European stock markets took investors on a tumultuous
roller-coaster ride. They staged an incredible rally in the first half of the
year, returning 27%, as measured by the Morgan Stanley Capital International
(MSCI) Europe Index in U.S. dollars. But investor anxiety hit Europe hard in
August. Double-digit declines were almost universal and many of the stock
markets gave up almost half of the gains made earlier in the year.

The decline was partly in reaction to the falling U.S. market, but it also
reflected fears of exposure to economic turmoil in Russia. Then in the last
quarter of the year, as central banks around the world lowered interest rates
and enthusiasm built in Europe for the year-end monetary union, the MSCI Europe
Index regained momentum and recouped what it had lost over the summer to end the
year up 29%.

Finland's stock market alone returned 123% in 1998, thanks in part to its strong
telecommunications and electronics industries. The worst market in Europe was
Norway. Hammered by sagging oil prices, the Oslo Stock Exchange fell 30%.

Asian returns were dominated by the contraction of the region's economy.
Japanese stocks had a positive return to U.S. investors only because the yen
appreciated against the dollar.

The weakening dollar, aided by signs of economic stabilization, also pushed
Thailand into positive territory. Only the Australian, Korean and Philippine
markets rose in their own currencies.

Bonds

Flight-to-Quality Investing Breeds Illiquidity

What did fixed-income investors want most in 1998? In two words, Quality and
Liquidity. During the volatile market conditions that characterized much of the
year, they fled to the highest-quality government securities--U.S.
Treasuries--even if it meant paying more and receiving lower returns.

The U.S. Treasury is the world's largest issuer of debt. Moreover, that debt is
backed by the full faith and credit of the federal government. Treasuries were
therefore an ideal "safe haven" investment. Major European government bond
markets were another safe port amid last year's global financial storm.

As a result of this "flight to quality," bond markets in late summer and early
October were plagued by illiquidity, or difficulty buying and selling all but
the most sought-after Treasuries. Growing demand for Treasuries fueled such a
strong rally that the yield on the 30-year Treasury bond fell to 4.71% on
October 5, its lowest level since April 1967. (Bond yields move in the opposite
direction of prices.) Yields on Treasury notes and bills also sank as a huge
inflow of cash into money market funds prompted portfolio managers to buy
short-term government securities.

These sharp drops meant that the spread, or difference in yield, between
Treasuries and other debt securities, such as investment-grade corporate bonds,
widened significantly, indicating investors were less willing to take a chance
on the relatively more risky bonds.

An even more dramatic indication of illiquidity was investors' strong preference
for "on the run," or the most recently auctioned, Treasuries versus "off the
run," or older, less-frequently traded issues. Both offer the same credit
quality. Yet the spread between yields of "on the run" and "off the run"
Treasuries, which might normally be a few basis points, rose to as much as 40
basis points in some cases. (A basis point is 1/100th of a percentage point.)
This wide gap reflected investors' willingness to pay more and accept lower
returns for greater liquidity.

This stampede away from both risky and safe bonds was one of the major factors
that spurred the Federal Reserve to action. Had the trend been allowed to
continue, it might have threatened the U.S. economic expansion. The Federal
Reserve cut the Federal funds rate (what banks charge each other to borrow
overnight) by a quarter percentage point on September 29, October 15 and
November 17. The reductions left the key short-term rate at 4.75%. The
mid-October move did the most to restore liquidity to the bond markets, as this
marked the first time in four and a half years that monetary policy was changed
between the central bank's regularly scheduled meetings. The unusual timing of
this move encouraged investors and spurred lenders to provide businesses with
money and should help foster U.S. economic growth in the future.

By the end of the year, the battered bond markets had staged a respectable
recovery. Investors had begun to shift money out of Treasuries back into
investment-grade and high yield corporate bonds as well as emerging market,
mortgage-backed and asset-backed securities.

1999 Investment Outlook

Economic Outlook

Slow Growth and Tame Inflation

Our economists at Prudential expect the economy to slow to a 2% pace in the
first half of 1999, but they do not expect the deceleration to be sharp. First,
the U.S. economy has more momentum than expected. This growth has come from
solid sources such as consumer expenditures, not from short-term factors such as
fluctuations in inventories. Second, a sharp increase in bank lending, narrowing
credit spreads and a rebound in the stock market have for the most part silenced
talk of a severe credit crunch. Lastly, recent employment reports and vehicle
sales indicate that above-trend growth still continues. Our economists are also
calling for growth to increase to 3% in the second half of the year as
businesses stock up on inventories in anticipation of Year 2000 computer
problems.

We believe inflation will remain tame in 1999. Inflation, as measured by the
Consumer Price Index, is expected to level out at 2.25%. The Consumer Price
Index, which climbed 2% in the second half of 1998, is expected to rise by 2.4%
in the first half of 1999 and settle at 2.2% in the latter half. Oil prices
remain the biggest wild card in our inflation forecast. According to our
economists and most Wall Street firms, as Asia recovers and more seasonable
colder weather descends upon the United States and Japan, oil prices should
rise.

These projections imply that the Federal Reserve is not likely to tinker with
U.S. monetary policy in 1999 through further cuts in interest rates.

Stock Market Outlook

Reconsider Expectations

Markets generally bring prices in line with earnings performance sooner or
later. Although the market may rise in 1999, the likelihood that it will match
the phenomenal gains of the last four years is not very high. Since the stock
market leaders have become very expensive relative to their earnings prospects,
investors may want to consider directing some assets to the underpriced sectors
of the market.

Time to Rebalance

The disparity in returns (and valuations) among market sectors, investment
styles and capitalization groupings reminds us of the importance of
diversification and a long-term view. Rarely does the top-performing sector of
the market remain the same over time.

Investors interested in rebalancing should consider value stocks, which in
general are selling at significant discounts to the market, as well as small-
and mid-cap growth stocks. Many of these companies have strong pricing power. In
addition, given their strong performance in the fourth quarter of last year,
emerging markets and Asia may be starting their recovery at very inexpensive
levels. One place we believe investors should stay put is Europe, where the bull
market has yet to run its course. The advent of the new currency, the Euro, is
expected to lead to a large-scale restructuring of investment portfolios, which
may favor the larger, more familiar European companies.

- --------------------------------------------------------------------------------

A Reality Check

Since 1925, the U.S. stock market's average return has been 11.2% as measured by
the S&P 500 Index. Yet in recent years, returns have been much higher, as the
chart below shows.

are slowing, we believe it is prudent to remember that recent rates of return
are unlikely to continue.

U.S. Bond Markets

Guarded Optimism

While last summer's wariness will not easily be forgotten, many investors are
once again embracing fixed-income markets with guarded optimism. Much will
depend on how the U.S. economy fares. The manufacturing arm is coming out of a
recession and service-sector growth could continue at a brisk, if somewhat
slower, pace than last year. Some Asian economies have begun to improve,
pointing toward stronger demand for American-made machinery and other industrial
goods.

These and other signs indicate that the U.S. economy is on course to make a soft
landing in 1999. In other words, the economy should grow at a slower pace but
avoid sliding into a recession. The three Federal funds rate cuts enacted late
last year could act as a safety net, encouraging economic growth through lower
borrowing costs. But it usually takes between nine months and a year for an
interest rate cut to work its way through the economy. This leaves plenty of
time for the economy to lose steam.

By some measures, the average spread, or difference in yield, between junk bonds
and Treasuries was just over 600 basis points at year-end (according to the
Chase High Yield Index). Although this spread is down from the more than 700
basis points of last summer, it is still much higher than the 400 to 500 basis
points that would be expected with the junk bond default rate currently at its
historical average of 3.0%. In short, we believe junk bonds are somewhat
undervalued right now considering the level of risk involved.

If the economy behaves as expected, the yield on the 30-year U.S. Treasury bond
should fluctuate in a fairly narrow range between 4.75% and 5.75% this year.
Investment-grade and high yield corporate bonds should perform better than
federal government securities as investors seek securities that provide
incremental yield over Treasuries. In fact, demand for junk bonds and
investment-grade corporate bonds has already increased in the new year because
they are viewed as beneficial additions to a portfolio in the low-rate
environment.

Prices of investment-grade corporate bonds have recovered roughly half of their
losses from last year, depending on which sector of the market is considered.
For example, financial services bonds bounced back solidly, but energy bonds
have gained only modestly amid continued concern about the impact of low oil
prices. Overall, corporate balance sheets are still in good shape as debt as a
percentage of equity is still at manageable levels.

Bargain hunters should also look to the municipal bond market, where the average
insured, triple-A-rated bond maturing in 30 years was yielding approximately 95%
as much as comparable Treasuries at year-end. Historically, these bonds have
yielded roughly 87% of what Treasuries yield, because their interest income is
exempt from federal income taxes and, in some cases, state and local taxes as
well.

Prudential Money Market Portfolio

Performance Summary.

Your Portfolio returned 5.39% during 1998 and beat the 5.10% return on the
average money market fund as tracked by Lipper Analytical Services, Inc. On
December 29, 1998, the Portfolio's seven-day yield was 4.96%, down from 5.28% on
June 30, 1998.

Money market interest rates fluctuated in a narrow range, then declined sharply
in midsummer as the global financial crisis led the Federal Reserve to lower
short-term interest rates. Your Portfolio provided an above-average return by
investing in shorter- and longer-term money market securities that allowed it to
lock in higher yields in the first half of 1998 and to weather the period of
lower interest rates that occurred during the second half of 1998.

An investment in the Prudential Series Fund Money Market Portfolio is neither
insured nor guaranteed by the U.S. government. There is no guarantee that the
Portfolio will be able to maintain a stable share value of $10.

Performance Review.

Rates Tumbled. After holding fairly steady in the first half of 1998, interest
rates began to tumble in August as financial market turmoil spread from Asia to
Russia and Latin America.

Investors fled to the relative safety of U.S. Treasuries. As a result, the
difference in yield between Treasuries and other debt securities widened
significantly.

To protect the U.S. economy from the disarray in the financial markets, the
Federal funds rate (the rate banks charge each other for overnight loans) was
lowered three times in quarter-percentage-point increments to 4.75%.

The decline in the Portfolio's seven-day yield reflects these changes in
monetary policy.

Strategy Session.

U.S. Economy Sent Mixed Signals

The outlook for U.S. monetary policy changed several times during 1998 as
investors revised their predictions about how much the Asian financial crisis
would hurt U.S. economic growth.

Grappling with signs of economic weakness and strength early in the year,
investors initially thought the economy would slow enough to require a cut in
the Federal funds rate to stimulate growth. Instead, the economy raced ahead in
early 1998, fueling speculation that a short-term rate increase was necessary to
curb the expansion. However, this view faded in the spring amid renewed fears
that Asian financial woes would sap U.S. economic vigor.

These concerns deepened in August as the financial crisis hit Russia and Latin
America. Investors sought refuge in U.S. Treasuries, causing them to become
overvalued relative to investment-grade and lower-quality debt securities. The
Federal Reserve responded by cutting the Federal funds rate a quarter
percentage point on September 29, October 15 and November 17, leaving the key
short-term rate at 4.75%.

The unusual timing of the second move, which occurred between the central bank's
regularly scheduled meetings, reassured investors that monetary policy would be
reduced as often as needed to soften a potential economic slowdown.

For the year, the best buying opportunities occurred at the end of the first,
second and fourth quarters, when seasonal borrowing needs of corporations
briefly boosted yields so that money market securities traded at "fire sale"
prices.

Once it became clear in late summer that the Federal funds rate was headed
lower, we advantageously positioned the Portfolio to beat the anticipated
decline in interest rates. The Portfolio ended the year positioned in a neutral
fashion versus its competition.

Federal Reserve Seen on Hold.

"We believe the Federal Reserve will hold monetary policy steady for now because
the U.S. economy remains quite strong and thus far, Brazilian economic woes have
inflicted far less damage on global financial markets than was originally
expected."

Prudential 
Diversified Bond Portfolio

Performance Summary.

Corporate bonds performed better than U.S. Treasuries early in the year as U.S.
economic conditions remained favorable and financial turmoil in Asia appeared to
have eased. However, the Asian financial crisis deepened and spread to other
regions, prompting investors to buy Treasuries for their relative safety and
sell other debt securities. Treasuries therefore gained more than corporate
bonds and emerging market debt securities in 1998.

While your Portfolio's exposure to Treasuries increased, its corporate debt
holdings included energy sector bonds that declined in value as well as Conti
Financial Corp. bonds that hurt the Portfolio's relative performance. As a
result, the Portfolio's 7.15% annual return trailed the 7.44% return on the
Lipper (VIP) Corporate Debt BBB Average.

Investment Goal

High level of income over the long term while providing reasonable safety of
capital.

Types of Investments

U.S. government securities, mortgage-backed bonds, both investment-grade and
high yield ("junk bond") corporate debt, and foreign securities (dollar and
non-dollar denominated).

Investment Style

This Portfolio seeks the highest yield while maintaining safety of capital, by
strategically allocating Portfolio assets among the above classes of bonds.

- --------------------------------------------------------------------------------

Performance Review.

What a Rally! The Portfolio's performance benefited as U.S. Treasuries comprised
roughly 30% of its total investments when the rally in Treasuries peaked in
early October.

At that time, prices of Treasuries soared so high that the 30-year Treasury bond
yield, which falls as prices rise, slid to its lowest level in more than 30
years.

Disappointment over a modest change in U.S. monetary policy on September 29 had
boosted demand for "safe haven" securities such as Treasuries relative to stocks
and corporate bonds.

This trend fueled strong gains in the prices of Treasuries during the first week
of October.


                                       12

Strategy Session.

A Confident Beginning. Early in the year, a nearly ideal combination of subdued
inflation, solid U.S. economic growth and low interest rates enhanced the appeal
of securities such as corporate bonds that offered incremental yield over U.S.
Treasuries. Belief that some Asian nations were making progress toward resolving
their financial difficulties also heightened investor confidence. Thus,
investment-grade corporate bonds performed better than Treasuries during the
first five months of the year, based on Lehman Brothers indexes.

This trend reversed as the Asian financial contagion deepened and infected
Russia and Latin America in August. To make matters worse, the Federal Reserve
had to arrange a rescue of hedge fund Long-Term Capital Management, which nearly
collapsed in September. Investors responded by purchasing Treasuries and dumping
assets that carried greater risk. We were in this camp, increasing Treasuries to
30% of the Portfolio's total investments as of September 30, 1998, up from 2.0%
from December 31, 1997.

The global financial crisis posed a potential threat to the U.S. economy because
many investors were reluctant to buy the stocks and bonds of corporations. The
Federal Reserve came to the rescue again, protecting the economy with a series
of three quarter-percentage-point cuts in the Federal funds rate (what banks
charge each other for overnight loans). The first reduction on September 29 left
the rate at 5.25%. Investors expressed their dissatisfaction with this modest
change by purchasing Treasuries, which pushed down the 30-year Treasury bond
yield to 4.71% in early October, its lowest level since April 1967.

The Federal funds rate was lowered again to 5.00% on October 15 and 4.75% on
November 17. The unusual timing of the second move, which occurred between the
Federal Reserve's regularly scheduled meetings, seemed to indicate that monetary
policy would be eased as often as needed to aid U.S. economic growth. Reassured,
investors began to reverse the "flight to quality" trend.

As prices of our U.S. dollar-denominated bonds of the cities of Moscow and St.
Petersburg, Russia, edged higher, we sold them at a loss on the view that
difficult economic and financial conditions would continue in Russia. The
Portfolio's performance was also hurt because its energy bonds sold off amid
concern that low oil prices would continue to hurt corporate balance sheets. In
addition, we owned Conti Financial Corp. bonds that performed poorly as major
U.S. credit rating agencies down-graded their ratings.

Outlook

PORTFOLIO MANAGER
Barbara Kenworthy

Economy Expected to Moderate.

"We believe the U.S. economic expansion could moderate in 1999. In other words,
the economy could grow at a slower pace but not slide into a recession. If the
economy behaves as expected, the 30-year Treasury bond yield could fluctuate
this year in a range of 4.75% to 5.75%. Therefore, debt securities that offer
incremental yield over Treasuries stand a good chance of performing better than
federal government securities in 1999."

Prudential Conservative Balanced Portfolio

Performance Summary.

Your Portfolio--which invests in a conservative mix of bonds, stocks and money
market securities--returned 11.74%, for the year ended December 31, 1998, well
above the average bond return. However, it trailed the 14.79% return of the
Lipper (VIP) Balanced Fund Average because the Portfolio's conservative mandate
requires a smaller proportion of stocks in the asset allocation than the typical
balanced portfolio. Active management of our asset allocation added to the
Port-folio's performance, but both our bonds and the portion of our stocks that
are actively managed trailed their benchmarks.

Investment Goal

Favorable total return consistent with a more conservatively managed diversified
portfolio.

Types of Investments

Money market instruments, bonds and common stocks of both established and
smaller companies.

Investment Style

The Portfolio management team holds a baseline allocation of 35% stocks, 35%
bonds and 30% money market instruments.

- --------------------------------------------------------------------------------

Performance Review.

We Added Value with Active Asset Allocation. We kept our money market allocation
considerably below our benchmark, shifting the allocation to intermediate-term
bonds. By year's end, we also held nearly 40% of the Portfolio's assets in
stocks. We invested 80% of the stocks in a strategy designed to match the risk
and return characteristics of the S&P 500 Index. That strategy paid off in 1998,
as the S&P 500 Index outpaced most active equity managers.

A Poor Year for Value Stocks. The actively managed portion of our stock
allocation favors companies trading at attractive prices for their earning
potentials. These stocks did not participate in the stock market rally.

Bond Markets Became Very Focused. After Russia defaulted on some debt, bond
investors focused on U.S. Treasury bonds. Although we had reduced our exposure
to corporate and foreign issuers early in the year, a few remaining holdings
performed poorly.

Strategy Session.

Active Asset Allocation. We use a mathematical model to compare the expected
return on the entire stock market (determined primarily by prices and estimated
earnings) to long-term interest rates. We try to increase the proportion of the
asset class (e.g., stocks, bonds or money market instruments) that offers the
best value at any time. We believe asset class has a greater impact on returns
over the long term than selection of individual securities. Therefore, these
shifts in allocation may affect your return significantly. However, because of
the Portfolio's conservative mandate, active asset allocation plays a smaller
role than it does in the Flexible Managed Portfolio. Your equity allocation is
shared between a portion managed to mirror the behavior of the S&P 500 Index and
a portion actively managed in a value style.

Value Investing. Research has shown that a value style has beaten growth over
the long run, particularly because it holds up better in falling markets. This
wasn't true over the past 12 months, because investors behaved in an unusual way
this year. They tended to favor stocks that already were expensive, instead of
emphasizing better values. We believe this was a panic reaction, not typical of
normal investor behavior. In addition, our value style has led us away from
stocks of the largest firms. The market-leading stocks reached record levels of
price-to-earnings ratios--60 to 70 times annual earnings per share and more. We
don't believe those ratios, many times higher than historical levels, can be
sustained over the long term.

Mid-sized and Small Companies. Historically, stocks of firms with small market
capitalization (the total value of all outstanding stock) have tended to
outperform stocks of their larger counterparts. Unfortunately, the opposite
occurred in 1998, with small-company stocks trailing larger by the widest margin
since 1929. While the reason for this underperformance remains elusive, lower
earnings growth, low inflation and the global financial crisis probably all
contributed to the underperformance. Over the long term, we believe these
smaller stocks should outpace larger and more expensive stocks.

Bond Markets Calmer. In mid-1998, a Russian default led bond investors to focus
on only the very safest securities. The bonds of even the strongest corporations
became much less expensive than Treasury bonds of similar maturity.
Fortunately, we had reduced our exposure to these bonds before the bond market
fell in late summer. We believe the price differences between corporate and
Treasury bonds should narrow somewhat in 1999 and are maintaining our emphasis
on corporate bonds.

- --------------------------------------------------------------------------------

Outlook

PORTFOLIO MANAGER
Mark Stumpp

Finding Misvaluations.

"We expect a better investing environment in 1999. The continued volatility in
stock and bond markets can make opportunities for our portfolio managers by
creating misvaluations between stock and bond prices that our active asset
allocation may exploit. Nineteen ninety-eight was the fifth consecutive year of
underperformance by both mid-sized company and value-oriented stocks. We do not
expect this performance discrepancy to persist. If the past is any guide, these
stocks may go through a period of superior performance in the near future."

Performance Summary.

Your Portfolio--which invests in an actively managed mix of stocks, bonds and
money market securities had a disappointing year in 1998. Although the overall
return of 10.24% was good, it could have been better in a year that saw the
Lipper (VIP) Flexible Fund Average rise by 13.50%. The portion of your stocks
that is actively managed in a value style substantially trailed the S&P 500
Index.

Performance Review.

A Good Year for Indexing. Early in the year we invested about one-half of the
Portfolio's stocks in a style designed to mirror the risk and return of the S&P
500 Index. 

The overall stock market was dominated by the performance of a few stocks
contained in the Index. These few stocks rose so much that the Index
outperformed most active stock managers.

We Added Value with Active Asset Allocation. We kept cash levels to a minimum
and over the year we actively shifted assets between stocks and bonds.

A Poor Year for Value Stocks. Half of our stocks are managed with an active
style that has a significant exposure to stocks of mid-sized companies with
strong earning potential trading at attractive values. These stocks did not
participate in the stock market rally.

should narrow somewhat in 1999 and are maintaining our emphasis on corporate
bonds.

PORTFOLIO MANAGER

Finding Misvaluations.

"We expect a better investing environment in 1999. The continued volatility in
stock and bond markets can make opportunities for our portfolio managers by
creating misvaluations between stock and bond prices that our active asset
allocation may exploit. Nineteen ninety-eight was the fifth consecutive year of
underperformance by both mid-sized company and value-oriented stocks. We do not
expect this performance discrepancy to persist. If the past is any guide, these
stocks may go through a period of superior performance in the near future."

Prudential High Yield Bond Portfolio

Performance Summary.

High yield bonds (commonly referred to as junk bonds) went on a roller-coaster
ride in 1998. Prices climbed earlier in the year, only to tumble later on as
deepening turmoil in global financial markets prompted investors to purchase
U.S. Treasuries for their relative safety and sell assets that carried greater
risk. High yield bonds rallied again later in the year as the Federal Reserve
eased monetary policy three times to protect the U.S. economic expansion. 

Your Portfolio returned -2.36% for the year and lagged the 0.10% gain on the
average high yield fund tracked by Lipper Analytical Services, Inc., because
some of its lower-rated bonds sold off more sharply than its higher-quality debt
securities.

Investment Goal 

High total return.

Types of Investments

Primarily noninvestment-grade bonds. These bonds have speculative
characteristics and are subject to greater credit and market risk than
higher-quality securities. 

Investment Style 

Concentrates primarily on junk bonds that appear to offer an attractive
combination of high current income and attractive total return.

Performance Review.

A Bumpy Ride. In the first seven months of the year, high yield bonds led all
other sectors of the taxable bond markets, according to Lehman Brothers indexes.

However, that period was followed by one of the most difficult three
months in the history of junk bonds. Many investors shunned all types of risky
securities (including high yield bonds) after a financial crisis spread beyond
Asia to Russia and Latin America in August. 

Your Portfolio's performance over the past year generally reflected these ups
and downs of the high yield market.

Strategy Session.

A Strong Start. A resilient U.S. economy grew rapidly for most of the year,
despite a marked decline in manufacturing exports to Asia. Inflation remained
subdued as the economy expanded and long-term interest rates in the U.S.
lingered at low levels. These nearly ideal economic conditions spurred demand
for high yield bonds earlier in the year as investors wanted debt securities
that provided incremental yield over U.S. Treasuries. As a result, junk bonds
performed better than Treasuries during the first seven months of 1998. 

However, demand for high yield bonds began to dry up in the eighth month. The
financial whirlwind that first struck Asia slammed into Russia and Latin America
in August, sending global financial markets reeling. Investors purchased
supersafe U.S. Treasuries and sold riskier assets such as high yield bonds.

Junk bonds had been the leading fixed-income asset class in July, but they
ranked second-lowest in August, based on Lehman Brothers indexes. The largest
declines occurred in lower quality junk bonds such as those rated single-B,
which accounted for approximately 50% of your Portfolio's total investments as
of August 31, 1998. 

Financial markets deteriorated further in September as the Federal Reserve had
to arrange the rescue of Long-Term Capital Management. This giant hedge fund's
near-collapse, left some investors even more reluctant to buy nongovernment
bonds. Had this trend continued it could have endangered the U.S. economic
expansion because of a lack of willingness to provide businesses with money.

To protect the U.S. economy, the Federal Reserve cut the Federal funds rate
(what banks charge each other for overnight loans) by a quarter percentage point
on September 29, October 15 and November 17, leaving it at 4.75%.

Investors began to return to the junk bond market in earnest during November.
Bonds rated single-B rallied strongly, because they had been oversold. These
gains benefited your Portfolio, which returned 2.56% for the fourth quarter of
1998. However, the Portfolio's annual return was negative, because about 29% of
its total investments were in nonrated and Caa-rated bonds that only partially
recouped their earlier losses.

Outlook

PORTFOLIO MANAGER
George W. Edwards, CFA

High Yield Market Shows Promise.

"The credit quality of the high yield bond market will likely remain
fundamentally sound as long as the U.S. economy continues to expand. Meanwhile,
the difference between yields of lower- to middle-quality junk bonds and
comparable U.S. Treasuries is at wide levels typically characteristic of a
weaker economy."

Prudential Stock Index Portfolio

Performance Summary.

Your Portfolio returned 9.32% for the second half of 1998 and gained 28.42% over
the course of the year. Despite a 19% drop early in the second half, the
Portfolio rebounded sharply in the latter part of the year. Last year, we
reported that the three-year run of above 20% returns was unprecedented. Now we
have added a fourth year to the run.

The global financial crisis, triggered by events in Asia and Russia, led to the
initial drop in the market when investors became uneasy with the financial
situation in emerging markets. However, the growing U.S. economy and subsiding
fears of a global financial meltdown, led investors to feel more confident. In
turn, the S&P 500 Index's return was well above historical standards. 

Standard & Poor's neither sponsors nor endorses the Stock Index Portfolio.
Investors cannot directly invest in any index, including the S&P 500 Index.

      calculated by Lipper Analytical Services, Inc., and reflects the
      investment return of certain portfolios underlying variable life and
      annuity products. These returns are net of investment fees and fund

      market value of the common equity of 500 stocks primarily traded on the
      New York Stock Exchange. The S&P 500 is an unmanaged index that includes
      the reinvestment of all dividends but does not reflect the payment of
      transaction costs and advisory fees associated with an investment in the
      Portfolio.

Performance Review.

The Stock Index Portfolio attempts to hold all 500 stocks included in the S&P
500 Index and to duplicate its performance. Portfolio manager John W.
Moschberger manages the Portfolio by investing funds received while trying to
minimize commissions and transaction costs.

Technology Led the Way. The Index was led by the technology sector, which
returned almost 73% for the year. Stock prices of companies on or associated
with the Internet rose to unparalleled highs in the latter half of 1998. The
demand for computer systems and software was strong, driving prices of these
stocks higher as well. Communications services, wireless, long distance and
local telephone service had the second-highest return for the year at about 52%.
The Internet explosion propelled returns in both the technology and
communications services sectors.

Health Care and Consumer Cyclicals Had a Strong Year. The S&P 500 Index's health
care stocks returned 44% for the year. Stocks of drug retailers and drug
companies were the best-performing areas of the health care sector. Consumer
cyclicals, companies that perform better when an economy is growing, produced a
36% return. Furthermore, consumer staple stocks, such as restaurants and
pharmaceuticals, achieved a 22% gain. Moreover, the Index's heavily weighted
financial sector, rebounding from investor fears about emerging markets,
returned 11%. The utility sector also bounced back from a slow end to the first
half of the year to post an overall 15% return.

Energy Stocks Were Weak Again. The energy sector, hurt by oil prices dropping to
a 12-year low, returned only 0.5%. However, this was not the Index's
worst-performing sector. Basic material stocks were pulled down by commodity
prices at a 10-year low--copper prices dropped to their lowest average of the
century. This sector was down more than 6% for the year.

- --------------------------------------------------------------------------------

Outlook

PORTFOLIO MANAGER
John W. Moschberger

Keep Your Expectations Realistic.

"For the fourth successive year the S&P 500 Index exceeded a 20% return. Last
year, we warned that a third year was unprecedented. The year was very unusual
in another way: the Index did not reflect the performance of most stocks listed
on it. The S&P 500 Index is weighted by market capitalization--the largest
companies count for more. This year, the largest 10% of companies in the Index
accounted for much of its performance. An equally weighted index would have
gained only 11% instead of 29%. Typically, the gap is only a few percentage
points. It has not been this large in 40 years. Because of this, most
actively-managed mutual funds trailed our fund. These are unusual times, and it
is particularly important to keep in mind that past performance is no guarantee
of future behavior."

Prudential Equity Income Portfolio

Performance Summary.

Over the past year, your Portfolio returned -2.38%, while the Lipper (VIP)
Equity Income Average gained 16.21%. 

Investors, afraid of the global consequences of the recession in Asia, showed a
strong preference for the stocks of a few large growth companies. Because the
Equity Income Portfolio adheres to a disciplined value investing style, we owned
smaller companies. In contrast with 1997, these smaller-company stocks performed
poorly, pulling our return slightly negative. In particular, we had substantial
holdings of Real Estate Investment Trusts (REITs), and the market became very
unfavorable to this sector.

Our financial stocks--particularly Lehman Brothers (an investment bank) and our
Real Estate Investment Trusts--contributed to both last year's strong
performance and this year's weak one.

Investment Goal

Current income and capital appreciation.

Types of Investments

Primarily stocks and convertible securities with prospects for income returns
above those of the S&P 500 Index.3

Investment Style 

The Portfolio uses a "value" investment approach to companies that are
attractively priced relative to book value, earnings, discretionary cash flow,
sales and other measures of value.

- --------------------------------------------------------------------------------

Performance Review.

Size Counted. Although the stock market rebounded, the largest 10% of the S&P
500 Index gained substantially more than smaller companies. We had avoided these
stocks because they have been expensive for some time. The less-expensive
mid-sized companies that we thought were better values lost favor. 

Financials Suffered. These stocks have strong prospects for earnings-growth but
are undervalued, in our opinion.

Basic Industry Lagged. Our industrial and energy holdings generally lagged the
strong market, and Pioneer Natural Resources, an independent exploration and
production company, suffered because its production was below prior estimates.
With the current surplus of oil supply over demand, we don't consider that a
problem.


                                       22

Strategy Session.

We remain focused on industrials, financials, and consumer cyclicals. We believe
that today, Real Estate Investment Trusts (REIT) offer the best combination of
current dividend yield and long-term dividend growth, because further
securitization of real estate should allow substantial cash flow growth
potential.

Not only are there economies of scale in purchasing furnishings, materials,
etc., but the REIT mechanism provides the funding for superior managers to
leverage their abilities by acquiring additional property. Ease in buying and
selling (liquidity) also makes real estate investment trusts more attractive.

Although short-term fears pushed the price of REIT shares below the value of
their underlying properties, we think well-managed companies eventually will
trade at a premium because of the added value of the REIT structure.

Our industrials and our consumer cyclicals (such as autos, retailers and
housing-related companies) reflect our confidence that the U.S. economy will
continue to expand. Despite some Asia-induced slowing in 1998, the economy is
fundamentally strong.

However, companies that tend to do well in a growing economy--the industrial
issues in particular--were priced in 1998 as though a recession was imminent.
This makes them very inexpensive in terms of what we must pay for a dollar of
their earnings.

- --------------------------------------------------------------------------------

Outlook

PORTFOLIO MANAGER
Warren E. Spitz

Value Investing for the Long-term.

"In 1997, several of our investment themes paid off strongly. We believe that
investors saw the value in several of our holdings, but their favorable opinions
were swamped this year in a widespread fear-driven movement to the stocks of a
very few large and well-known companies. Investors behaved in an unusual way
this year. They tended to move toward stocks that already were expensive,
instead of toward better value. We believe this was a panic reaction, not
typical of investor behavior. In recent years, my value style has led me away
from stocks of the largest firms. The market-leading stocks reached record
levels of price-to-earnings ratios--60 to 70 times annual earnings per share and
more. I don't believe those are conservative investments over the long term."

Performance Summary.

Your Portfolio returned 9.34% in 1998, trailing the Lipper (VIP) Growth Fund
Average of 24.94% for the period. In this fourth year of S&P 500 Index returns
above 20%, gains were particularly concentrated in a few large growth stocks
that had already become expensive when the year began. Our value discipline
steered us away from such stocks. Our return also was held back by poor returns
on our retailers, by our substantial cash holding over the year, and by our
relatively small participation in the high-performing technology sector.

Despite our defensive cash holdings and a market that was unfavorable to our
in-vestment style, our return was near the historical average for the S&P 500
Index.

Investment Style

believed to be temporarily undervalued relative to the companies' sales,
earnings, book value and cash flow.

- --------------------------------------------------------------------------------

Performance Review.

Size Counted. Concerned about the impact of the Asian recession, investors
focused strongly on the largest growth companies. We avoided these stocks,
because they have been expensive for some time.

Retailers Were Mixed. In the retail industry, we held inexpensive stocks, such
as Dillards, Tandy and Toys R Us. They performed poorly, while popular stocks
such as Wal-Mart and Home Depot rose even farther.

Not Enough Tech. When Compaq bought Digital Equipment, we benefited both from
the sale and afterward from the return on the Compaq stock we acquired.
Nonetheless, our relatively small holdings in the technology sector constrained
our performance.

And Too Much Cash. Our average cash balance of about 14% held back our return.
However, we reduced our cash sharply over the year, acquiring some
bargain-priced stock after the market fell.


                                       24
<PAGE>
 
Strategy Session.

We Are Disciplined Deep Value Investors. The S&P 500 Index has had an
unprecedented four successive years of gains above 20%. This year, these gains
were particularly concentrated in a few large growth stocks that had already
become expensive when the year began, but our value discipline steered us away
from such stocks--we avoid stocks that are priced well above the market average
for comparable earnings.

Over the long run, value stocks have performed quite well. However, there have
been other multi-year periods that favored growth stocks. The two investment
styles have alternated in superior performance, so we believe investors should
have exposure to both.

We Still Like Financial Companies. Morgan Stanley Dean Witter was among the
largest contributors to last year's return. We also liked financial firms that
were less favorably treated last year, as investors worried about emerging
market exposure and natural disaster damage claims. Loews, Chubb, Safeco and
Citi-group are among our larger holdings. Financial companies have been leaders
in applying technology to drive down costs and improve services while
consolidating to increase productivity.

Consumers Still Going Strong. Consumer spending has kept the U.S. economy strong
recently, when exports and investment flagged. Chrysler made a substantial
contribution to our 1998 return. We continue to have a focus on retailers and
housing-related firms.

- --------------------------------------------------------------------------------

Outlook

PORTFOLIO MANAGER
Thomas R. Jackson

Staying the Course.

"Value and growth investing styles historically have alternated in periods of
superior performance. The growth style has had the advantage for several years
now, bringing the differences in stock value to extraordinary levels. In 1998,
S&P 500 Index growth stocks rose more than 27 percentage points above the return
on S&P 500 value stocks. The entire Index, pulled up by large growth stocks,
returned 16 percentage points more than the average stock. That is the largest
discrepancy in 40 years. Chasing the strategy that worked last year is a
well-known investing fallacy. Portfolio managers do best over the long run when
they stick to one investment style. That's what we're doing--consistent value
investing so when the current imbalances correct themselves, we'll be there to
reap the rewards."

Performance Review.

Technology. Our technology stocks were the foundation of our strong performance,
led in large measure by the impact of the Internet on the demand for personal
computers, networking equipment and semiconductors.

Our fairly large positions in Cisco Systems, Microsoft and Oracle made strong
contributions.

Telecommunications services companies such as MCI WorldCom, Airtouch
Communications, and Qwest Communications were also helped by the explosion of
Internet traffic.

Financials. Financial companies were hurt in midyear by fears of exposure to
emerging markets, but our holdings bounced back, spurred by Federal Reserve cuts
in interest rates and the easing of the world financial crisis.

Strategy Session.

Earnings Are Important. The pace of earnings growth for U.S. companies has been
dropping steadily over the past year. Investors have focused on companies that
continue to deliver rapid growth through the current difficulties.

If a wider range of companies resume rapid earnings growth, investor interest
may broaden and is likely then to favor stocks that are considerably less
expensive than today's market leaders.

We Have a Two-Pronged Strategy for This Environment. On the one-hand, we own
companies that are currently high-priced and rising, because of their strong
earnings: our drug companies, retail companies, some of our technology stocks
and telecommunications companies. We also own companies that are relatively
inexpensive now because they are in the early stages of what we believe will be
a profit recovery.

Our Largest Sectors. Technology, financial services, pharmaceuticals and
retailing remain our largest sectors. They should continue to benefit from lower
interest rates. Moreover, the health care and technology sectors are growing
strongly, while the retail sector is reducing its costs. The market's emphasis
on earnings should sustain its focus on these groups.

- --------------------------------------------------------------------------------

Outlook

PORTFOLIO MANAGER
David T. Poiesz

Price-sensitive Growth Investing.

"We buy the best growth companies we can find at prices that don't fully reflect
their future prospects. We aim at a portfolio that captures faster growth than
the market overall, but at an attractive price. We are watching the world
economic situation carefully with an eye on how it can affect the businesses of
specific companies. For example, we are trying to avoid excess exposure to banks
that may be affected by a Latin America slowdown."

Prudential Global Portfolio

Performance Summary.

Your Portfolio returned 25.08% in 1998, almost nine percentage points above the
16.19% gain of the Lipper (VIP) Global Average. We had a substantial focus on
continental Europe, the best-performing region over our reporting period, and
our stocks there performed well.

We benefited from having very little invested in emerging markets, such as
eastern Europe, and relatively little in any Asian market. Our
large-capitalization U.S. growth stocks had above-average returns.

The Portfolio may invest in foreign securities. Foreign investments are subject
to the risks of currency fluctuation, political and social risks and
illiquidity.

Performance Review.

Europe and the U.S. We had a substantial focus on continental Europe, and this
region was the best-performing region in 1998. Except for about 7% of our assets
invested in Asia, our assets were invested in Europe and the United States,
where economies were growing the fastest.

Continental Banks. Our largest industry is banking. An Italian bank, Credito
Italiano, bounced back strongly and had an excellent annual return.

Technology. Our focus was on technology stocks, particularly telecommunications
services and equipment companies--such as Nokia, and Cisco Systems.

These companies served us well over the past year. Software companies, notably
the global giant Microsoft, also made large contributions to our strong annual
performance.


                                       28

Strategy Session.

Location: Europe. We have allocated almost half of our assets to Europe and more
than a third to the United States. We believe currency unification in Europe
will boost their markets. In addition to introducing a strong incentive to
improve productivity and growth, it should reduce trade and financing costs. It
also is improving consumer morale.

Europe is seeing many private companies restructure to improve their
productivity and governments selling businesses they own. Simultaneously, low
interest rates and new bank-managed mutual funds are attracting savings to the
stock market. As in the U.S. a decade ago, these trends are good for stock
prices. 

The global economic picture is too uncertain to give us confidence in the growth
prospects of companies based in emerging markets. We are waiting for more
stability before we increase our investments there.

Industries: For some time, we have liked the telecommunications
industry--including Nokia and Vodafone--and the financial services industry in
Europe. European bank stocks were hurt during the summer panic about exposure to
the debt of emerging market countries, including Russia. Most of our bank
holdings had little or no exposure, but even these stocks declined. They bounced
back as investors recovered their perspective.

The United States. In recent years, our Portfolio has had significantly less
U.S. investment than the size of the U.S. stock market would warrant, because
large growth stocks in the U.S. stock market have been relatively expensive.
Since the economic crisis in emerging markets, however, we own more in the U.S.
than we usually would because economic growth is most secure at home. Our
domestic stocks include Safeway, Microsoft, Time Warner and PMC--Sierra, all of
which have been performing well.

Outlook

PORTFOLIO MANAGERS
Daniel J. Duane, Ingrid Holm, Michelle Picker

Still Cautious.

"Investors' reaction to Brazil's devaluation shows that they are still reacting
strongly to any threat to economic growth. Stocks whose earnings depend on
expanding economies (cyclicals) or to emerging markets tended to drop sharply.
We prefer companies that have great growth prospects within Europe or the United
States. Certain basic services, such as communications and banking, are changing
dramatically, whatever happens to the global economy. We try to benefit from
those trends."

                      NOTES TO THE FINANCIAL STATEMENTS OF
                             CERTAIN PORTFOLIOS OF
                        THE PRUDENTIAL SERIES FUND, INC.
 
NOTE 1:  GENERAL
 
The Prudential Series Fund, Inc. ("Series Fund"), a Maryland corporation,
organized on November 15, 1982, is a diversified open-end management investment
company registered under the Investment Company Act of 1940, as amended. The
Series Fund is composed of fifteen Portfolios ("Portfolio" or "Portfolios"),
each with a separate series of capital stock. The information presented in thse
financial statements pertains to only the ten Portfolios available for
investment by Variable Universal Life: Money Market Portfolio, Diversified Bond
Portfolio, Conservative Balance Portfolio, Flexible Managed Portfolio, High
Yield Bond Portfolio, Stock Index Portfolio, Equity Income Portfolio, Equity
Portfolio, Prudential Jennison Portfolio and Global Portfolio. Shares in the
Series Fund are currently sold only to certain separate accounts of The
Prudential Insurance Company of America ("The Prudential"), Pruco Life Insurance
Company and Pruco Life Insurance Company of New Jersey (together referred to as
the "Companies") to fund benefits under certain variable life insurance and
variable annuity contracts ("contracts") issued by the Companies. The accounts
invest in shares of the Series Fund through subaccounts that correspond to the
Portfolios. The accounts will redeem shares of the Series Fund to the extent
necessary to provide benefits under the contracts or for such other purposes as
may be consistent with the contracts. The ability of the issuers of the
securities held by the Money Market Portfolio to meet their obligations may be
affected by economic developments in a specific industry or region.
 
NOTE 2:  ACCOUNTING POLICIES
 
The following is a summary of significant accounting policies consistently
followed by the Series Fund in preparation of its financial statements.
 
SECURITIES VALUATION:  Securities traded on an exchange (whether domestic or
foreign) are valued at the last reported sales price on the primary exchange on
which they are traded. Securities traded in the over-the-counter market
(including securities listed on exchanges for which a last sales price is not
available) are valued at the average of the last reported bid and asked prices
or at the bid price on such day in the absence of an asked price. Convertible
debt securities are valued at the mean between the most recently quoted bid and
asked prices provided by principal market makers. High yield bonds are valued
either by quotes received from principal market makers or by an independent
pricing service which determine prices by analysis of quality, coupon, maturity
and other factors. Any security for which a reliable market quotation is
unavailable is valued at fair value as determined in good faith by or under the
direction of the Series Fund's Board of Directors.
 
The Money Market, Conservative Balanced and Flexible Managed Portfolios use
amortized cost to value short-term securities. Short-term securities that are
held in the other Portfolios which mature in more than 60 days are valued at
current market quotations and those short-term securities which mature in 60
days or less are valued at amortized cost.
 
The High Yield Bond Portfolio may hold up to 15% of its net assets in illiquid
securities, including those which are restricted as to disposition under
securities law ("restricted securities"). Certain issues of restricted
securities held by the High Yield Bond Portfolio at December 31, 1998 include
registration rights, some of which are currently under contract to be
registered. Restricted securities, sometimes referred to as private placements,
are valued pursuant to the valuation procedures noted above.
 
REPURCHASE AGREEMENTS:  In connection with transactions in repurchase agreements
with U.S. financial institutions, it is the Series 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 Series Fund may
by delayed or limited. (See Note 5).
 
FOREIGN CURRENCY TRANSLATION:  The books and records of the Series Fund are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars on the following basis:
 
(i) market value of investments securities, other assets and liabilities - at
the current rates of exchange.
 
                                       88
<PAGE>
 
(ii) purchases and sales of investment securities, income and expenses - at the
rate of exchange prevailing on the respective dates of such transactions.
 
Although the net assets of the Series Fund are presented at the foreign exchange
rates and market values at the close of the fiscal year, the Series Fund does
not isolate that portion of the results of operations arising as a result of
changes in the foreign exchange rates from the fluctuations arising from changes
in the market prices of securities held at the end of the fiscal year.
Similarly, the Series Fund does not isolate the effect of changes in foreign
exchange rates from the fluctuations arising from changes in the market prices
of long-term portfolio securities sold during the fiscal year. Accordingly,
these realized and unrealized foreign currency gains (losses) are included in
the reported net realized gains (losses) on investment transactions.
 
Net realized gains (losses) on foreign currency transactions represent net
foreign exchange gains or losses from holdings of foreign currencies, currency
gains or losses realized between the trade and settlement dates on security
transactions, and the difference between the amounts of dividends, interest and
foreign taxes recorded on the Series Fund's books and the U.S. dollar equivalent
amounts actually received or paid. Net unrealized currency gains or losses from
valuing foreign currency denominated assets and liabilities (other than
investments) at fiscal year end exchange rates are reflected as a component of
net unrealized appreciation (depreciation) on investments and foreign
currencies.
 
Foreign security and currency transactions may involve certain considerations
and risks not typically associated with those of domestic origin as a result of,
among other factors, the possibility of political and economic instability and
the level of governmental supervision and regulation of foreign securities
markets.
 
FORWARD CURRENCY CONTRACTS:  A forward currency contract is a commitment to
purchase or sell a foreign currency at a future date at a negotiated forward
rate. Certain portfolios of the Series Fund enter into forward currency
contracts in order to hedge their exposure to changes in foreign currency
exchange rates on their foreign portfolio holdings or on specific receivables
and payables denominated in a foreign currency. The contracts are valued daily
at current exchange rates and any unrealized gain or loss is included in net
unrealized appreciation or depreciation on investments. Gain or loss is realized
on the settlement date of the contract equal to the difference between the
settlement value of the original and renegotiated forward contracts. This gain
or loss, if any, is included in net realized gain (loss) on foreign currencies.
Risks may arise upon entering into these contracts from the potential inability
of the counterparties to meet the terms of their contracts.
 
SHORT SALES:  Certain portfolios of the Series Fund may sell a security it does
not own in anticipation of a decline in the market value of that security (short
sale). When the Portfolio makes a short sale, it must borrow the security sold
short and deliver it to the buyer. The proceeds of the short sale will be
retained by the broker-dealer through which it made the short sale as collateral
for its obligation to deliver the security upon conclusion of the sale. The
Portfolio may have to pay a fee to borrow the particular security and may be
obligated to remit any interest or dividends received on such borrowed
securities. A gain, limited to the price at which the Portfolio sold the
security short, or a loss, unlimited in magnitude, will be recognized upon the
termination of a short sale if the market price at termination is less than or
greater than, respectively, the proceeds originally received.
 
OPTIONS:  The Series Fund may either purchase or write options in order to hedge
against adverse market movements or fluctuations in value with respect to
securities which the Series Fund currently owns or intends to purchase. The
Series Fund's principal reason for writing options is to realize, through
receipts of premiums, a greater current return than would be realized on the
underlying security alone. When the Series Fund purchases an option, it pays a
premium and an amount equal to that premium is recorded as an investment. When
the Series Fund writes an option, it receives a premium and an amount equal to
that premium is recorded as a liability. The investment or liability is adjusted
daily to reflect the current market value of the option. If an option expires
unexercised, the Series Fund realizes a gain or loss to the extent of the
premium received or paid. If an option is exercised, the premium received or
paid is an adjustment to the proceeds from the sales or the cost of the purchase
in determining whether the Series Fund has realized a gain or loss. The
difference between the premium and the amount received or paid on effecting a
closing purchase or sale transaction is also treated as a realized gain or loss.
Gain or loss on purchased options is included in net realized gain (loss) on
investment transactions. Gain or loss on written options is presented separately
as net realized gain (loss) on written option transactions.
 
The Series Fund, as writer of an option, may have no control over whether the
underlying securities may be sold (called) or purchased (put). As a result, the
Series Fund bears the market risk of an unfavorable change in
 
                                       89
<PAGE>
 
the price of the security underlying the written option. The Series Fund, as
purchaser of an option, bears the risk of the potential inability of the
counterparties to meet the terms of their contracts.
 
FINANCIAL FUTURES CONTRACTS:  A financial futures contract is an agreement to
purchase (long) or sell (short) an agreed amount of securities at a set price
for delivery on a future date. Upon entering into a financial futures contract,
the Series Fund is required to pledge to the broker an amount of cash and/or
other assets equal to a certain percentage of the contract amount. This amount
is known as the "initial margin". Subsequent payments, known as "variation
margin", are made or received by the Series Fund each day, depending on the
daily fluctuations in the value of the underlying security. Such variation
margin is recorded for financial statement purposes on a daily basis as
unrealized gain or loss. When the contract expires or is closed, the gain or
loss is realized and is presented in the statement of operations as net realized
gain (loss) on financial futures contracts.
 
The Series Fund invests in financial futures contracts in order to hedge its
existing portfolio securities or securities the Series Fund intends to purchase,
against fluctuations in value. Under a variety of circumstances, the Series Fund
may not achieve the anticipated benefits of the financial futures contracts and
may realize a loss. The use of futures transactions involves the risk of
imperfect correlation in movements in the price of futures contracts and the
underlying assets.
 
SECURITIES LENDING:  The Series Fund (excluding the Money Market Portfolio) may
lend its portfolio securities to broker-dealers, qualified banks and certain
institutional investors. The loans are secured by collateral in an amount equal
to at least the market value at all times of the loaned securities plus any
accrued interest and dividends. During the time the securities are on loan, the
Series Fund will continue to receive the interest and dividends or amounts
equivalent thereto, on the loaned securities while receiving a fee from the
borrower or earning interest on the investment of the cash collateral. Loans are
subject to termination at the option of the borrower or the Series Fund. Upon
termination of the loan, the borrower will return to the lender securities
identical to the loaned securities. The Series Fund may pay reasonable finders',
administrative and custodial fees in connection with a loan of its securities
and may share the interest earned on the collateral with the borrower. The
Series Fund bears the risk of delay in recovery of , or even loss of rights in,
the securities loaned should the borrower of the securities fail financially.
 
SECURITIES TRANSACTIONS AND INVESTMENT INCOME:  Securities transactions are
recorded on the trade date. Realized gains and losses on sales of securities are
calculated on the identified cost basis. Dividend income is recorded on the
ex-dividend date; interest income, which is comprised of four elements: stated
coupon, original issue discount, market discount and market premium is recorded
on the accrual basis. Certain portfolios own shares of real estate investment
trusts ("REITs") which report information on the source of their distributions
annually. A portion of distributions received from REITs during the year is
estimated to be a return of capital and is recorded as a reduction of their
costs. Expenses are recorded on the accrual basis which may require the use of
certain estimates by management. The Series Fund expenses are allocated to the
respective Portfolios on the basis of relative net assets except for expenses
that are charged directly at a Portfolio level.
 
CUSTODY FEE CREDITS:  The Series Fund, exclusive of the Global Portfolio, has an
arrangement with its custodian bank, whereby uninvested monies earn credits
which reduce the fees charged by the custodian. Such custody fee credits are
presented as a reduction of gross expenses in the accompanying Statement of
Operations.
 
TAXES:  For federal income tax purposes, each portfolio in the Series Fund is
treated as a separate taxpaying entity. It is the intent of the Series Fund to
continue to meet the requirements of the Internal Revenue Code applicable to
regulated investment companies and to distribute all of its net income to
shareholders. Therefore, no federal income tax provision is required.
 
Withholding taxes on foreign dividends, interest and capital gains have been
provided for in accordance with the Series Fund's understanding of the
applicable country's tax rules and regulations.
 
DIVIDENDS AND DISTRIBUTIONS:  Dividends and distributions of each Portfolio are
declared in cash and automatically reinvested in additional shares of the Fund.
The Money Market Portfolio will declare and reinvest dividends from net
investment income and net realized capital gain (loss) daily. Each other
Portfolio will declare and distribute dividends from net investment income,if
any, quarterly and net capital gains, if any, at least annually. Dividends and
distributions are recorded on the ex-dividend date.
 
                                       90
<PAGE>
 
Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.
 
RECLASSIFICATION OF CAPITAL ACCOUNTS:  The Series Fund accounts for and reports
distributions to shareholders in accordance with the American Institute of
Certified Public Accountants' Statement of Position 93-2: Determination,
Disclosure, and Financial Statement Presentation of Income, Capital Gains, and
Return of Capital Distributions by Investment Companies. As a result of this
statement, the Series Fund changed the classification of distributions to
shareholders to disclose the amounts of undistributed net investment income and
accumulated net realized gain (loss) on investments available for distributions
determined in accordance with income tax regulations. For the year ended
December 31, 1998, the application of this statement increased (decreased)
undistributed net investment income ("UNI") and accumulated net realized gains
(losses) on investments ("GL") by the following amounts:

Net investment income, net realized gains and net assets were not affected by
these reclassifications.
 
NOTE 3:  AGREEMENTS
 
The Series Fund has an investment advisory agreement with The Prudential.
Pursuant to this agreement The Prudential has responsibility for all investment
advisory services and supervises the subadvisers' performance of such services.
The Prudential has entered into a service agreement with The Prudential
Investment Corporation ("PIC"), which provides that PIC will furnish to The
Prudential such services as The Prudential may require in connection with the
performance of its obligations under the investment advisory agreement with the
Series Fund. In addition, The Prudential has entered into a subadvisory
agreement with Jennison Associates LLC ("Jennison"), under which Jennison
furnishes investment advisory services in connection with the management of the
Prudential Jennison Portfolio. The Prudential compensates Jennison for its
services as follows: 0.75% on the first $10 million of that Portfolio's average
daily net assets, 0.50% on the next $30 million, 0.35% on the next $25 million,
0.25% on the next $335 million, 0.22% on the next $600 million and 0.20%
thereafter. The Prudential pays for the cost of PIC's services, compensation of
officers of the Series Fund, occupancy and certain clerical and administrative
expenses of the Series Fund. The Series Fund bears all other costs and expenses.
 
The investment advisory fee paid to The Prudential is computed daily and payable
quarterly, at the annual rates specified below, of the value of each of the
Portfolio's average daily net assets.

Portfolio), the portion of the investment advisory fee for that Portfolio equal
to the amount that the aggregate annual ordinary operating expenses (excluding
interest, taxes and brokerage commissions) exceeds 0.75% of the Portfolio's
average daily net assets. No refund was required for the year ended December 31,
1998.
 
PIC and Jennison are indirect, wholly-owned subsidiaries of The Prudential.
 
The Series Fund has a credit agreement (the "Agreement") with an unaffiliated
lender. The maximum commitment under the Agreement is $250,000,000. The
Agreement expired on December 18, 1998 and has
 
                                       91
<PAGE>
 
been extended through February 28, 1999 under the same terms. Interest on any
such borrowings outstanding will be at market rates. The purpose of the
Agreement is to serve as an alternative source of funding for capital share
redemptions. The Series Fund did not borrow any amounts pursuant to the
Agreement during the year ended December 31, 1998. The Series Fund pays a
commitment fee at an annual rate of .055 of 1% on the unused portion of the
credit facility. The commitment fee is accrued and paid quarterly by the Series
Fund.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF THE PRUDENTIAL SERIES FUND, INC.:
 
In our opinion, the accompanying statements of assets and liabilities, including
the portfolios 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 the Money Market, Diversified Bond,
Conservative Balanced, Flexible Managed, High Yield Bond, Stock Index, Equity
Income, Equity, Prudential Jennison and Global Portfolios (ten of the fifteen
portfolios that constitute The Prudential Series Fund, Inc.; the "Portfolios")
at December 31, 1998, the results of each of their operations for the year then
ended, the changes in each of their net assets for each of the two years in the
period then ended and the financial highlights for each of the three 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 Portfolios'
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, 1998 by correspondence with the
custodian and brokers, provide a reasonable basis for the opinion expressed
above. The accompanying financial highlights of the Prudential Jennison
Portfolio for the period April 25, 1995 through December 31, 1995 and the
financial highlights for each of the two years in the period ended December 31,
1995 for each of the other nine portfolios were audited by other independent
accountants, whose opinion dated February 15, 1996 was unqualified.

                       The  Prudential Series Fund, Inc.

                     Supplement dated February 26, 1999 to
                         Prospectus dated May 1, 1998

 
The following disclosure replaces in its entirety the seventh paragraph under 
the heading, "Investment Objectives and Policies of the Portfolios - Balanced 
Portfolios - Flexible Managed Portfolio" in the Prospectus:


                The bond portion of this portfolio will primarily be invested in
        securities that have a rating at the time of purchase within the four
        highest grades determined by Moody's, S&P, or a similar nationally-
        recognized rating service. A description of corporate bond ratings is
        contained in the Appendix to the statement of additional information.
        However, up to 25% of the bond component of this portfolio may be
        invested in securities having ratings at the time of purchase "BB," "Ba"
        or lower, or if not rated, of comparable quality in the opinion of the
        portfolio manager. These securities are considered speculative and high
        risk. The risks of medium to lower rated securities, are described in
        the Prospectus in connection with the High Yield Bond Portfolio. Up to
        20% of the bond portion of this portfolio may be invested in United
        States currency denominated debt securities issued outside the United
        States by foreign or domestic issuers. The established company common
        stock component of this portfolio will consist of equity securities of
        major corporations that are believed to be in sound financial condition.
        In selecting stocks of smaller capitalization companies, the portfolio
        manager may invest in companies that show above average profitability
        (measured by return-on-equity, earnings, and dividend growth rates) with
        modest price/earnings ratios or alternatively, in companies whose stock
        is undervalued relative to other stocks in the market. The individual
        equity selections for this portfolio may have more volatile market
        values than the equity securities selected for the Equity Portfolio or
        the Conservative Balanced Portfolio. The portfolio may also invest in
        preferred stock, including below investment grade preferred stock, and
        other equity-related securities. The money market portion of the
        portfolio will hold high quality money market instruments of the kind
        held by the Money Market Portfolio. Moreover, when conditions dictate a
        temporary defensive strategy or during temporary periods of portfolio
        structuring and restructuring, the Flexible Managed Portfolio may
        invest, without limit, in high quality money market instruments of the
        kind held by the Money Market Portfolio.

The following disclosure replaces in its entirety the seventh paragraph under 
the heading, "Investment Objectives and Policies of the Portfolios - Balanced 
Portfolios - Flexible Managed Portfolio" in the Prospectus:

               The facts that this portfolio will invest in a mix of common 
               stocks regarded as having higher risks than the mix of common
               stocks that will be purchased by the Conservative Balanced
               Portfolio; that the bond portion of its portfolio will include a
               higher percentage of bonds having ratings at the time of purchase
               of "BB, "Ba" or lower (or if unrated, of comparable quality); and
               that the "normal" mix for this portfolio will include a higher
               percentage of stocks all combine to mean that the risk of
               investing in this portfolio is relatively higher - to the extent
               that each of these factors results in greater risks - than the
               risk of investing in the Conservative Balanced Portfolio.

Whether providing insurance protection for home, family, and business, providing
for future education and retirement expenses, or offering innovations like
Critical Care Access, Prudential has always been able to deliver something more:
personal service, quality, attention to detail and the financial strength of The
Rock(R). Since 1875, Prudential has been helping individuals and families meet
their financial needs.
