LETTER FROM THE VICE CHAIRMAN
- --------------------------------------------------------------------------------
 
TO THE OWNERS OF NYLIAC CORPORATE SPONSORED VARIABLE UNIVERSAL LIFE POLICIES:
 
I am pleased to present the NYLIAC Corporate Sponsored Variable Universal Life
(CSVUL) Annual Report for the year ending December 31, 1998.
 
The Annual Report contains valuable financial information including year-end
performance data and separate account financial statements for each of the 18
investment divisions that are available with our NYLIAC CSVUL policies. NYLIAC
Corporate Sponsored Variable Universal Life Separate Account-I serves as the
separate account for these policies. This book also contains the following
annual reports:
 
    MainStay VP Series Fund, Inc.
     The Alger American Fund
     Calvert Variable Series, Inc.
     Fidelity Variable Insurance Products Fund
     Fidelity Variable Insurance Products Fund II
     Janus Aspen Series
     Morgan Stanley Dean Witter Universal Funds, Inc.
 
LIFE INSURANCE PROTECTION WITH A VARIETY OF INVESTMENT OPTIONS
 
The investment options offered with the NYLIAC CSVUL policies consist of 18
investment divisions and a fixed account. As a CSVUL policyowner, you benefit
from the experience and professional management of leading investment advisors.
The extensive selection of diversified investment offerings gives flexibility in
customizing a policy to suit individual investment styles. Please refer to a
current CSVUL Prospectus for a complete description of the investment divisions.
The following is our view of the current and anticipated economic conditions
that could affect the performance of the investment divisions.
 
ECONOMIC ENVIRONMENT YEAR-END REVIEW
 
The U.S. economy had another stellar year of rapid growth and low inflation in
1998, as a sharply deteriorating trade deficit and shrinking manufacturing
sector were more than offset by surging domestic demand. Real Gross Domestic
Product (GDP) rose by an estimated 3.7%, near its 1997 performance and still
well above virtually all estimates of the economy's non-inflationary growth
potential. As a result, the unemployment rate continued to decline -- from 4.7%
in December 1997 to 4.3% in December 1998, the lowest rate since 1970.
 
Nevertheless, inflation remained remarkably subdued during the year, with the
Consumer Price Index (CPI)(1) rising by 1.6% over the 12 months ending in
December (vs. 1.7% in 1997 and 3.3% in 1996). The strong dollar, along with
falling prices of oil and other commodity prices, helped keep inflation in check
despite rising wages and strong demand.
 
Bond yields continued their downward cycle, with treasury yields reaching their
lowest levels since the 1960's. Earlier in the year, the Federal Reserve Board
adopted a tightening bias due to concerns about an overheating economy and a
soaring stock market. Later in 1998, however, with credit and liquidity spreads
soaring in response to plunging oil and other commodity prices, deteriorating
economic conditions in the rest of the world, a Russian debt default, and the
bailout of a heavily leveraged hedge fund, the Federal Reserve lowered interest
rates by 75 basis points in three easing moves. This, combined with similar
moves by other central banks around the world, greatly eased the stress in
financial markets and provided some insurance against recession. The positive
stock market response helped encourage consumers to keep spending.
 
In 1999, growth is expected to finally slow as weakness in manufacturing spreads
to other economic sectors. Inflation is likely to pick up, but only slightly as
the unemployment rate begins to drift upward again and import competition
continues to restrain domestic prices. Bond yields may fall further, and some
additional Federal Reserve easing is likely once there is clear evidence of
slower growth. Later in the year, however, growth is expected to begin
strengthening again in response to Federal Reserve easing and improving
conditions abroad.
 
For the stock market, 1998 demonstrated overall solid performance combined with
major volatility. The Dow Jones Industrial Average(2) ended the year with a gain
of 18.1%. The S&P 500 Index(3) was up an even stronger 28.6% for an
unprecedented fourth year of increases exceeding 20%. However, the bull market
suffered a severe interruption from mid-July until the end of August, and could
well have been down for the year if not for the timely action of the Federal
Reserve and other central banks. Market conditions for 1999 are likely to be
mixed.
 
                                        2

Corporate profits are likely to suffer from slower growth and continuing margin
pressures from abroad. Interest rates could well reach a trough during the year.
Uncertainties about the millennium bug may worry investors. On the positive
side, the long-term outlook for the U.S. economy remains extremely favorable,
and prospects for the rest of the world are likely to improve.
 
FUNDING YOUR VARIABLE LIFE INSURANCE POLICY
 
As part of your long-term financial plan or corporate strategy, NYLIAC's CSVUL
product offers permanent life insurance protection with a variety of investment
options. One of the attractive features of your CSVUL policy is that a premium
payment schedule can be selected that is flexible enough to meet your needs.
 
The policy's fees and charges are deducted from the cash value, and your life
insurance coverage will remain in effect as long as your cash surrender value is
sufficient to cover these deductions. In order to help optimize potential
investment results for the future, you may increase your planned premium
payments or make additional, unplanned premium payments.
 
A higher level of premium funding may maximize the policy's investment potential
and reduce the likelihood that your policy will terminate due to lower than
anticipated investment performance, which could result in the cash surrender
value being insufficient to cover the required monthly deductions. Your
registered representative can assist you in evaluating the effects of different
premium funding levels so that you can make an informed choice.

Past performance is no guarantee of future results. Due to current market
volatility, the current performance may be less than the figures shown. The
investment return and the accumulation value of your policy will fluctuate so
that your contract, when surrendered, may be worth more or less than the
original cost. Performance reflects the percentage change for the period shown
with capital gains and dividends reinvested.
 
Performance reflects the deduction of the policy's current mortality and expense
risk charge of 0.70% for policy years one through ten and total fund operating
expenses. However, it does not reflect the policy fees or charges. These include
the cost of insurance, surrender charges, monthly contract charges, sales
expense charges, and premium and federal tax charges. Had these expenses been
deducted, total returns would have been lower.
 
NYLIAC assumed a portion of the expenses for the MainStay VP Convertible and the
MainStay VP International Equity Investment Divisions until 12/31/98 and for the
MainStay VP High Yield Corporate Bond and MainStay VP Value Investment Divisions
until 12/31/97. In addition, Janus Capital Corporation has agreed to reduce the
advisory fee for the Janus Aspen Series Balanced and the Janus Aspen Series
Worldwide Growth Investment Divisions and Morgan Stanley Dean Witter Investment
Management Inc. has agreed to reduce the advisory fee and assume certain
expenses of the Morgan Stanley Emerging Markets Equity Investment Division. Had
these expenses not been assumed or reduced, the total returns for these
Investment Divisions would have been lower.

minimum cost of insurance rates, please consult the prospectus.

MAINSTAY VP SERIES FUND, INC. PORTFOLIOS
 
MACKAY-SHIELDS FINANCIAL CORPORATION
 
ADVISER'S REPORT
 
Market Overview
 
Given a scenario of floundering Asian economies, a Russian financial crisis
which spread to Latin America, an American President undergoing impeachment, a
third quarter stock market correction, another bombing of Iraq, and finally the
collapse of one of the most respected hedge funds, one would expect investors to
react negatively. Instead, financial markets exhibited for a fourth straight
year unprecedented staying power and resiliency. The Dow Jones Industrial
Average(1) increased 18.13%, the S&P 500(2) (including income) advanced 28.58%
and the NASDAQ Composite(3) rose 39.63%.
 
However, what the numbers do not reveal is that only a handful of very large
capitalization stocks pushed up the averages, while the majority of smaller
issues trailed badly -- a continuation of the trends of the past three years.
The S&P 500 outshone the Dow Industrials because it includes such companies as
Microsoft, Dell Computer and Intel, the kind of companies that ruled the market.
This is despite the fact that big-stock valuations are at or near record levels
hit last July. In dramatic contrast, small capitalization stocks lost 2.55% as
represented by the Russell 2000(4). Traditional deep value investing also
suffered as these stocks sorely underperformed their large-cap growth peers,
with the lowest price-to-earnings stocks actually showing a loss for the year.
 
In addition to the large-cap effect, another factor contributed to the market's
rise during 1998. Internet-related companies, such as Amazon.com and eBay, saw
their stock prices more than double as Internet mania took over the investment
scene. The entire technology sector contributed heavily to the market's return
as many investors thought any computer-related business would benefit from the
increase in demand due to the Internet. Other highly performing industries
included entertainment and drug retailers.
 
There were few good markets on the international front during 1998. Investments
in Europe, where markets were anticipating monetary and economic unity, were for
the most part positive. On the other hand, the Asian financial crisis which
started with the Thai baht's devaluation in 1997, caused devaluation fears
around the world among investors, culminating in Russia's financial fiasco and
subsequently Latin America's. Complacent investors were suddenly and shockingly
confronted with the high degrees of risk they were assuming across emerging
markets. Volatility reached levels seldom experienced this century. The Dow
Jones had ten swings of more than 5% during 1998 -- twice the usual amount. Two
of those occasions were swings of greater than 15%.
 
Many investors embraced the perceived safety of U.S. Treasury bonds in 1998,
with the 30-year U.S. Treasury bond up 17.1%, more in line with historical stock
returns. For the bond market as a whole, many non-government bond sectors had
high volatility at best, losses at worst. 1998 was the first year since 1990
that safer bonds had higher returns than riskier bonds. In fact, 1998 was the
worst year for most risky bonds since 1990. Escalating concerns regarding
struggling Asian economies and developing problems in Latin America over the
summer caused a "flight to safety" to U.S. Treasuries.
 
Credited with bringing about stability and putting the stock market back on its
positive trajectory is Federal Reserve Chairman Alan Greenspan who led the move
to lower Federal Funds rates in September, October and November. Once convinced
that the Federal Reserve Board would do anything to prevent a financial
meltdown, many investors poured dollars back into the stock market, pushing
valuations to record high levels. Inflows into stock mutual funds returned to
positive territory after a negative August.
 
Even though the U.S. economy seems to be on sound footing with an accommodating
Federal Reserve, risks to the financial markets include a continuing malaise in
Southeast Asian and weak Latin American financial markets. Continuing
deflationary trends, not an economic scenario since the 1930s, and corporate
earnings disappointments could derail investor expectations of higher than
historical returns that we have experienced for the past several years.

Going forward, most economists see a slowly growing economy, continuing mild
inflation and relatively low interest rates. General demographic trends and
macroeconomic themes will continue to support equity investments into 1999.
Technological advances should help productivity and utilization of resources.
Stock market inflows should continue to be bolstered by U.S. baby boomers
properly saving for their retirement needs.

NEW YORK LIFE INSURANCE COMPANY
 
ADVISER'S REPORT
 
Market Overview
 
Global events dominated investment market news in 1998. Beginning with the Asian
debt market crisis, followed by the Russian economic meltdown of the summer,
global investment system signals started to flash "caution" to worldwide
investors at an increasing pace. These messages were offset by strong positive
signals from the U.S. economy, and to a lesser extent, from Europe.
 
Within the U.S., continued economic growth has been driven by strong corporate
competitiveness and robust job growth despite these shocks. A major contributor
to economic health has been the low level of inflation, producing quality
earnings and a stable capital planning platform for corporations. U.S. companies
have used their capital wisely, especially compared to some of the
"capital-burning" practices of certain Asian economies. The emergence of the
Euro as a common currency and prospects for improved economic integration have
provided positive fundamentals for Europe.
 
As a consequence, 1998 turned in another strong year of investment performance
for both stock and bond investors. Some bond investors were burned by the
emerging market disarray as the market adopted a more restrictive credit risk
stance. However, by and large most bondholders benefited by the decline in
longer term Treasury rates of almost 1% as the Federal Reserve cut rates three
times during the course of the year. Most stock investors fared even better as
the S&P 500(1) returned 28.6%. Despite some deceleration of U.S. corporate
profit growth, the stock market benefited from lower interest rates, record
levels of merger and acquisition activity, and strong inflows from mutual funds
and foreign investors.
 
Going forward, the fundamentals of low inflation, capital discipline, fiscal and
monetary strength combined with a healthy job market should provide for steady
growth. Offsetting these positive factors are the risk of further global
economic weakness in Japan or emerging market countries, Y2K dislocations or
unanticipated inflationary pressures. On balance, our outlook for 1999 remains
positive.
 
We see value in the bond sector, especially in the corporate bond market where
credit spreads have widened. We also have a positive outlook for the stock
market, but we anticipate notable disparities in performance by sector, further
accentuating a trend begun in 1998 where strong performance was concentrated in
a limited number of stocks.
 
The Portfolios we manage performed very well relative to their objectives in
1998. Further discussions by our managers regarding Portfolio performance and
market outlook for their respective sectors follow.

  large-capitalization companies in the technology and pharmaceutical sectors.
- - Our decision to reduce the Portfolio's positions in problem sectors such as
  energy contributed positively to performance.
- - The Portfolio outperformed the average Lipper Variable Products(1) capital
  appreciation portfolio, which returned 22.22% for the year.
 
MANAGEMENT DISCUSSION AND ANALYSIS
As years go, 1998 was one of the most volatile in recent memory. Despite its ups
and downs, however, the S&P 500 Index(2) closed the year with a 28.58% gain,
making 1998 the fourth year in a row domestic stocks in general have returned
more than 20.00%.
 
With financial problems in Asia, Russia, and Latin America, declining oil
prices, and weaknesses in other commodities, investors sought refuge in stocks
they felt were least likely to be affected by these difficulties. The market
focused on large-capitalization growth stocks that appeared to have steady and
predictable earnings prospects. Purely domestic issues continued to do well,
while oil and commodity-related stocks tended to show poor performance. The
technology sector as a whole made strong advances and pharmaceutical companies
generally performed well as new drug introductions and a stream of anticipated
advances helped push stock prices higher.
 
Declining interest rates improved earnings prospects for many companies in the
latter half of the year, and calm inflation also helped strengthen the stock
market's advance. Despite international tensions and impeachment action against
President Clinton, the stock market remained relatively strong at the end of the
year.
 
HOW DID THE MAINSTAY VP CAPITAL APPRECIATION PORTFOLIO PERFORM IN THIS MARKET
ENVIRONMENT?
Quite well. The MainStay VP Capital Appreciation Portfolio returned 38.14% for
the year-ended 12/31/98, outperforming the average Lipper Variable Products
capital appreciation portfolio, which returned 22.22% for the year.
 
HOW DID THE PORTFOLIO MANAGE TO DO SO WELL?
A number of factors contributed positively to the Portfolio's performance, but
we believe the most important factor was sticking to our strict investment
disciplines. We seek companies with strong growth prospects, considering factors
such as steady growth in revenues, accelerating earnings, and increasing
earnings per share. During the volatile market environment in 1998, we
concentrated on large-capitalization companies, which were among the stocks
investors favored when problems in foreign markets caused a flight to quality in
both the stock and bond markets. We also reduced the Portfolio's positions in
sectors we felt were weak, such as oil and energy. By concentrating on winners
and largely avoiding losers, the Portfolio had an excellent year.
 
WHICH SECTORS CONTRIBUTED MOST STRONGLY TO PERFORMANCE?
We don't select sectors. Instead, we choose stocks for the Portfolio based on
their individual merits after extensive quantitative analysis and fundamental
research. As a result of the Portfolio's selection process, however, we found a
number of technology stocks that we believed had strong growth potential and
they contributed to the Portfolio's significant outperformance. Despite various
setbacks throughout the year, the Portfolio remained overweighted in technology
stocks through all four quarters.
 
                                        9
<PAGE>   10
 
Pharmaceutical stocks also had an excellent year, and the Portfolio had a number
of holdings that did well. New drug introductions, direct-to-consumer
advertising, and a long pipeline of FDA-approved drugs awaiting release helped
advance the sector as a whole.
 
Consumer staples as a group showed relatively weak performance in 1998, but our
stock selection process positioned the Portfolio in relatively defensive, purely
domestic companies, such as supermarkets, which performed well at a time when
the market seemed to prefer stable growth and relatively predictable earnings.
As a group, supermarkets are benefiting from consolidation, which is helping
improve margins and profits.
 
CAN YOU GIVE SOME EXAMPLES OF TECHNOLOGY STOCKS THAT DID WELL?
Certainly. Lucent Technologies was the Portfolio's best-performing stock in 1998
and also our largest holding. The company has done exceedingly well, with the
value of the Portfolio's position more than tripling during the year.
 
In January, we purchased EMC, a stock we had owned and sold a few years ago. The
company is a leader in corporate data storage systems, hardware, and software.
We believed EMC had excellent potential, based on increasing dominance in the
company's market sector and rapidly accelerating earnings. The Portfolio's
position almost doubled in value during the year.
 
Compuware is a computer software company that was also among the Portfolio's
best performing stocks, and it more than doubled in value during the year.
 
DID ALL OF THE PORTFOLIO'S TECHNOLOGY STOCKS DO THAT WELL?
No, the Portfolio also held issues that showed relatively poor performance.
Computer Associates International is an example. The company's management team
announced that it might have difficulty closing large contracts, which led to
lower earnings estimates.
 
WHAT ABOUT PHARMACEUTICAL STOCKS?
Given the positive fundamentals in the pharmaceutical industry and the high unit
volume growth in a low inflationary environment, pharmaceuticals were generally
excellent performers. Although we increased the Portfolio's position in Pfizer,
our timing could have been better. In the first half of the year, many investors
were selling the stock to take profits after the release of Viagra. Since the
Portfolio seeks long-term capital appreciation, however, we looked at the
company's fundamentals and continued to hold the stock in the Portfolio, which
had a modestly positive impact for the year. During the year, we also increased
the Portfolio's position in Merck, a major drug company profiting from
successful names such as Pepcid AC, Propecia, and many others.
 
Other positive performers among drug stocks included Eli Lilly, a stock the
Portfolio has held for some time and Schering-Plough. Schering-Plough's Claritin
product for allergy sufferers helped sales, earnings, and stock performance.
Overall, pharmaceutical stocks accounted for a substantial portion of the
Portfolio's positive total return.
 
DID THE PORTFOLIO REMAIN OVERWEIGHTED IN FINANCIAL STOCKS IN 1998?
No, over the course of the year, we decreased the Portfolio's weighting in
financial stocks for a number of reasons. First, we believed that growth was
slowing in the financial sector. Second, the huge mergers in the financial
industry produced companies that were more difficult to analyze and evaluate.
 
The NationsBank merger with BankAmerica is a good example. The combination added
to the company's financial risk because BankAmerica was invested in the D. E.
Shaw hedge fund when the market had just suffered a major setback from a debacle
at Long Term Capital. Since the stock no longer fit the Portfolio's growth
criteria and risk profile, we sold out of the Portfolio's position, which had a
slightly negative impact. Although our decision to sell helped reduce portfolio
risk, the stock's subsequent performance suggested that the Portfolio would have
been rewarded for a more patient outlook.
 
Travelers Group, which the Portfolio had owned for several years, merged with
Citicorp to form Citigroup during the year, which reduced our overall confidence
level in the company. In particular, we were not certain the company would be
able to deliver the level of earnings the market expected. As a result, we cut
back on our holdings in Citigroup in the summer, which was not the best time to
sell, so the transaction had a negative impact on performance.
 
                                       10
<PAGE>   11
 
WHAT WERE SOME OF THE MAJOR PURCHASES THE PORTFOLIO MADE DURING THE YEAR?
In addition to the purchases we already mentioned, the Portfolio purchased Fred
Meyer, a large supermarket chain. We liked the company's fundamentals and
believed it might benefit from consolidation in the supermarket industry. The
Portfolio bought the stock midyear at an average price around $40 and in
September, the company announced that it would be acquired by Kroger, another of
the Portfolio's investments. By the end of the year, Fred Meyer stock was
trading around $60, for an increase of about 50% from the Portfolio's purchase
price.
 
In the second quarter, the Portfolio purchased Colgate-Palmolive. The company
has shown stable growth and was having success with its new Total toothpaste.
Despite the company's international exposure, we believed it could handle any
difficulties the market might generate. For the year, the stock was up 28%,
which was in line with the S&P 500 Index.
 
As new money came in over the course of the year, we used much of it to add to
the Portfolio's most successful positions, including Lucent Technologies, Cisco
Systems, EMC, and others. So our buying strategy paralleled our investment
strategy of sticking with the winners in the investment portfolio.
 
WERE ALL OF THE PORTFOLIO'S PURCHASES EQUALLY SUCCESSFUL?
No. We purchased HBO, a leading provider of health care software systems, during
the third quarter of 1998. The company looked attractive given its size, market
share, and growth rate. But shortly after we purchased the stock, they announced
an acquisition that the market didn't like. Next, the company decided to merge
with McKessen, a leading drug distributor. But miscommunication about the merger
caused the stock to substantially underperform the market. Although the stock
provided a positive return, it was substantially lower than other holdings, and
on a relative basis, had negative impact on the Portfolio's performance.
 
YOU MENTIONED SOME FINANCIAL STOCK SALES. WHAT ELSE DID THE PORTFOLIO SELL
DURING 1998?
Perhaps the Portfolio's most significant sales were in the energy sector. In
light of declining oil prices and weakening prospects of oil services companies
and exploration and drilling, we sold the Portfolio's positions in Diamond
Offshore Drilling, Halliburton, and ENSCO International. Since the impact of
energy service stocks was almost uniformly negative in 1998, we viewed the
timing of the sales as good news, even though the Portfolio lost money on each
of these transactions. The wisdom of reallocating the assets was further
underscored as oil prices continued to decline.
 
The Portfolio also sold toy maker Mattel during the first half of the year. We
saw deteriorating fundamentals, slowing growth, and weakening returns at the
company. Toys "R" Us made major inventory reductions on Mattel items and
Barbie's popularity appeared to be declining. As a result, we were pleased to
sell the Portfolio's position at a gain over its original purchase price,
although the Portfolio had a slightly negative return on the stock in 1998.
Again, we view the sale as a positive for the Portfolio, because the company
missed its earnings estimates each quarter and preannounced its fourth quarter
decline, which had a severely negative impact. But since the Portfolio no longer
owned the stock, we avoided most of the impact of these negative developments.
 
DID THE PORTFOLIO MAKE OTHER SIGNIFICANT SALES?
Yes. The Portfolio sold Tenet Healthcare and United Healthcare, both of which
saw decelerating earnings growth rates. Tenet is a large hospital chain that
missed its earnings projections. United Healthcare suffered from rising medical
costs and an inability to smoothly integrate recent acquisitions. Although both
companies declined after we sold the Portfolio's holdings, United Healthcare has
since recovered a bit. Nevertheless, we believe the sales were positive for the
Portfolio by allowing us to put the assets to better use elsewhere.
 
Adaptec is a technology company the Portfolio sold at a loss, after the Asian
crisis and slower earnings undercut the fundamental reasons for owning the
stock. The Portfolio sold the stock in the low twenties, and the price continued
to decline even further throughout most of the year.
 
Hewlett-Packard was a long-standing position in the Portfolio that simply failed
to live up to earnings expectations. The Portfolio sold the stock at a huge gain
over the Portfolio's original cost, but at a slight loss for the year.
 
WHICH STOCKS WERE THE PORTFOLIO'S WORST PERFORMERS IN 1998?
By far the worst stock was Cendant, which was plagued by news of accounting
irregularities at CUC International, prior to its merger with HFS in late 1997.
The stock, which was a major holding, was down nearly 44%
 
                                       11
<PAGE>   12
 
for the year. We continue to own the stock and believe the market has
overpenalized a company that is generating $1.5 billion of free cash flow.
 
Other poor performers included HEALTHSOUTH, a nationwide rehabilitation and
outpatient surgical provider, which surprised the market by missing earnings
projections and preannouncing that problems would continue until 1999. Conseco
is an insurance company that acquired Green Tree Financial, and suffered from
negative perceptions of its top management. Despite these and other negative
performers, the Portfolio was still able to outperform the market by a
substantial margin.
 
WERE THERE OTHER ASPECTS OF THE PORTFOLIO'S MANAGEMENT THAT HELPED OR HURT
PERFORMANCE?
Our focus during the year was primarily on the kinds of stocks the market
wanted -- large capitalization issues with consistent growth records and
relatively dependable and predictable earnings. While we couldn't predict the
problems in Russia or Brazil, we have always believed that strong stocks are
likely to get stronger on a relative basis when macroeconomic problems arise.
While we also couldn't predict specific company shortfalls, we believe the
Portfolio's diversification and stock selection process helped contribute to
excellent performance in 1998.
 
WERE THERE SPECIFIC WAYS YOU SOUGHT TO MANAGE THE PORTFOLIO'S RISK DURING THE
YEAR?
Leaving energy stocks was one step we took, with a positive overall impact on
performance. We also avoided the heavy overweighting in technology that some
funds pursued.
 
WHAT IS YOUR OUTLOOK GOING FORWARD?
 
We continue to view the market as highly volatile and generally unpredictable.
So instead of trying to time our investments or dodge and weave with the market,
we will continue to select companies with strong growth characteristics, solid
performance records, and reasons to perform well in the future. The Portfolio
invests for the long-term and we believe the market is willing to pay a premium
for companies that can show consistent growth potential over time.

MAINSTAY VP CASH MANAGEMENT PORTFOLIO
 
1998 MARKET RECAP
- - In 1998, the money markets were influenced in various ways by modest
  inflation, low unemployment, falling commodity prices, and a budget surplus
  that reduced Treasury issuance.
- - During the first half of 1998, the money market yield curve was flat and
  exhibited low volatility, while during the second half of the year, volatility
  increased dramatically.
- - Financial difficulties in Asia, Russia, and Brazil resulted in a flight to
  quality that raised demand for high-quality, highly liquid securities.
- - In the third quarter, problems at a major hedge fund disrupted market
  activity, making it difficult for any but the strongest issuers to raise money
  in the capital markets.
- - The Federal Reserve Board cut short-term interest rates three times between
  September and November in order to restore stability to the markets.
 
1998 PORTFOLIO RECAP
- - For the 12 months ended 12/31/98, the MainStay VP Cash Management Portfolio
  returned 5.18%.
- - Throughout the first half of the year, the Portfolio maintained its investment
  days to maturity in a relatively stable range, lengthening days to maturity in
  midsummer, when Russian and Latin American difficulties began to affect the
  market.
- - Concentration on top-tier securities helped the Portfolio outperform as
  spreads widened to near recession levels among second-tier names in the second
  half of the year.
- - The Portfolio outperformed the average Lipper(1) Variable Products money
  market portfolio, which returned 5.10% for the year-ended 12/31/98.
 
MANAGEMENT DISCUSSION AND ANALYSIS
Overall, 1998 was a year of extremes in the bond and money markets, causing
investors to reevaluate risk at several levels. The first half of the year saw
the lowest level of volatility in 15 years, while the second half of the year
reflected the highest volatility in 15 years.
 
A variety of forces fueled the progress of the income markets, including a
budget surplus that reduced Treasury issuance and tightened supply, and a flight
to quality in the third quarter of 1998 that dramatically increased demand for
government bonds. Fueled by financial problems in Asia, Russia, and Latin
America, and the near collapse of one of the world's largest hedge funds,
investors rushed to purchase high-quality, highly liquid issues, which was
generally positive for the money market.
 
Meanwhile, modest inflation, low unemployment, and a strong U.S. dollar provided
a positive economic backdrop, but earnings disappointments at leading
corporations caused wide swings in the stock market, eroding investor confidence
in the third quarter of 1998. Yield spreads on second-tier money market
instruments widened to near recession levels, while first-tier securities
remained strong on a relative basis. The Federal Reserve moved to stabilize the
situation by reducing interest rates three times in the third and fourth
quarters.
 
HOW DID THE MAINSTAY VP CASH MANAGEMENT PORTFOLIO PERFORM IN THIS MARKET
ENVIRONMENT?
The MainStay VP Cash Management Portfolio outperformed the average Lipper
Variable Products money market portfolio, which returned 5.10% over the one-year
period ending 12/31/98.
 
WHAT ACCOUNTED FOR THE PORTFOLIO'S ABOVE-AVERAGE PERFORMANCE?
Several factors contributed to the Portfolio's strong performance. In the first
half of the year, a flat yield curve provided few opportunities to add value by
changing days to maturity, so the Portfolio concentrated on securities with
yield-enhancing characteristics, such as domestic and Yankee issues, corporate
and asset-backed commercial paper, and floating-rate notes. Each of these helped
the Portfolio outperform in the first half of the year.
 
As financial difficulties in Russia and a major hedge fund setback began to rock
the markets, we lengthened the Portfolio's days to maturity, believing that the
Federal Reserve Board would likely adopt an accommodative policy to help
stabilize the situation. From September through November, the Federal Reserve
Board moved to reduce short-term interest rates three times, which had a
positive impact on the Portfolio's performance. When European central banks took
similar action, the Portfolio's positioning was further enhanced.
 
                                       13
<PAGE>   14
 
DID THE PORTFOLIO OWN ANY SECURITIES IN TROUBLED MARKETS?
No. The Portfolio maintained its high-quality orientation throughout the year,
avoiding emerging market debt and Latin American issues. Instead, it
concentrated entirely on top-tier money market instruments, which means
securities in the highest rating category. It did not own any split-rated issues
or second-tier securities during 1998.
 
WHAT TYPES OF YANKEE SECURITIES DID THE PORTFOLIO OWN?
The Portfolio invested in Yankee instruments from Canada, Western European
countries, and Australia. Most carried a long-term rating at or above AA.(2) The
Portfolio invested in Yankee banks that are among the largest banks in the world
and have strong franchises in their domestic markets.
 
DID ANY OF THE PORTFOLIO'S SECURITIES FACE PROBLEMS DURING THE YEAR?
No, they did not. This underscores the value of our decision to stick with the
highest-quality securities. In the second half of the year, spreads on
second-tier issues widened considerably, to near-recession levels. Since the
Portfolio did not own any of these securities, it did not face the negative
impact on performance that came with widening spreads.
 
WHERE DID THE PORTFOLIO INVEST ITS ASSETS?
Primarily in extremely liquid investments, such as commercial paper and bank
certificates of deposit, and floating-rate notes. The Portfolio did not invest
in more exotic securities such as callable CDs or other issues with imbedded
option features. Instead, the Portfolio stuck with relatively plain conservative
issues.
 
Regarding asset allocation, the Portfolio concentrated most heavily in
commercial paper and CDs from banks and bank holding companies. The Portfolio
also had a relatively strong weighting in top-tier asset-backed securities,
including asset-backed commercial paper, agency conventional mortgage loans,
trade receivables, and corporate loans. Since these securities offer higher
yields than ordinary commercial paper, they contributed positively to
performance without compromising quality. In selecting asset-backed securities
for the Portfolio, we look for high credit quality, strong cash flows backed by
collateral, and a highly rated credit enhancement.
 
WHAT IS YOUR OUTLOOK GOING FORWARD?
We expect the Federal Reserve Board to remain on hold for the early part of
1999, but believe they may have a bias toward easing interest rates later in the
year. We will manage the Portfolio's investment days to maturity accordingly.
While we remain optimistic, recent developments illustrate that risk is a major
investor concern and dislocations can easily occur in the money market as a
result of international developments or problems with corporate earnings.
Whatever happens, the Portfolio will continue to seek high-quality securities
that may provide a high level of current income consistent with preservation of
capital and liquidity.

MAINSTAY VP CONVERTIBLE PORTFOLIO
 
1998 MARKET RECAP
- - The U.S. stock market was highly volatile throughout 1998, but provided
  double-digit returns for the fourth consecutive year, with advances in
  large-capitalization issues masking corrections among small-cap and mid-cap
  stocks.
- - In general, companies benefited from low inflation throughout 1998 and
  declining interest rates in the second half of the year.
- - Financial problems in Asia, Russia, and Latin America caused severe setbacks
  in the convertible market from July through October, particularly for
  lower-rated issues as a general flight to high-quality bonds caused prices to
  drop in the high-yield market.
- - The convertible market saw tight yield spreads and throughout the year, many
  new issues carried low coupons and high premiums.
 
1998 PORTFOLIO RECAP
- - For the 12 months ended 12/31/98, the MainStay VP Convertible Portfolio
  returned 4.49%.
- - The Portfolio continued its risk-averse approach to convertible investing,
  which provided lower volatility than the market as a whole, but detracted from
  performance during the market recovery during the fourth quarter of 1998.
- - In the July to October period, the Portfolio sought opportunities among
  securities whose prices were severely reduced.
- - The Portfolio underperformed the average Lipper(1) Variable Products
  specialty/miscellaneous portfolio, which returned 28.41% for the year.
 
MANAGEMENT DISCUSSION AND ANALYSIS
As years go, 1998 was one of the most volatile in recent memory. Despite the
market's ups and downs, however, the S&P 500 Index(2) closed the year with a
28.58% gain, making 1998 the fourth year in a row domestic stocks in general
have returned more than 20.00%. Advances in large-cap growth stocks, however,
tended to mask corrections among various sectors of the small- and mid-cap
markets.
 
In the third quarter of 1998, financial problems in Asia, Russia, and Latin
America, declining commodity prices, and problems at a leading hedge fund,
generally caused a flight to quality. As many investors rushed to purchase the
largest and most liquid stocks and bonds, the convertible and high-yield bond
markets experienced severe setbacks, with liquidity all but evaporating for many
lower-rated issuers.
 
Beginning in late September, the Federal Reserve Board began to ease interest
rates in a series of moves that ultimately had a positive effect on both the
stock and bond markets. There was a rapid stock market recovery in the fourth
quarter, which left many defensively positioned investors at a relative
disadvantage. For the year, convertible securities provided only modest
returns -- well below those provided by large-capitalization stocks and
long-term Treasury bonds.
 
HOW DID THE MAINSTAY VP CONVERTIBLE PORTFOLIO PERFORM IN THIS MARKET
ENVIRONMENT?
The MainStay VP Convertible Portfolio returned 4.49% for the year-ended
12/31/98, underperforming the average Lipper Variable Products
specialty/miscellaneous portfolio, which returned 28.41% for the same period.
 
WHY DID THE PORTFOLIO UNDERPERFORM ITS PEERS?
A number of factors contributed to the Portfolio's underperformance, but the
most important was the decision to have the Portfolio remain defensively
positioned in a highly volatile market. Although the Portfolio seeks to
participate in the upside potential of the securities it selects, it also
typically seeks a measure of downside protection. When we believe that
securities are overpriced or likely to have the full downside potential of
equities, we tend to avoid them. While that strategy placed the Portfolio in the
top quartile for much of the year, particularly during highly volatile periods,
it resulted in underperformance when the stock market rallied in early July and
at the end of the year.
 
In 1998, the markets seemed to favor securities that didn't fit our style of
managing risk and reward. We saw a number of new issues that carried low coupons
and high premiums, with little room to provide protection in the event of a
market decline. We also saw preferred stock issues that we believed would behave
less like convertibles and more like common stock with a slightly higher
dividend. We used these securities sparingly, since they carried most of the
downside risk of the underlying stock, with only slightly better protection.
 
                                       15
<PAGE>   16
 
During the year, we also saw a tremendous interest in Internet stocks that
traded at levels we felt were unrealistic. In short, our willingness to
sacrifice upside potential to protect investors on the downside was the primary
reason the Portfolio underperformed its peers in the volatile markets of 1998.
 
WHAT WERE SOME OF THE POSITIVE FACTORS THAT INFLUENCED THE PORTFOLIO'S
PERFORMANCE?
Generally speaking, the Portfolio maintained an investment portfolio of higher
quality which was also part of our risk management strategy and worked well for
investors in difficult periods.
 
DID YOU MAINTAIN THE CREDIT QUALITY OF THE PORTFOLIO'S INVESTMENTS THROUGHOUT
THE YEAR?
During October, liquidity problems in the high-yield market presented purchasing
opportunities among lower-rated securities. With high-yield bond prices
generally dropping precipitously, the Portfolio was able to purchase some
lower-rated bonds at what we felt were bargain prices. That lowered the overall
quality of the Portfolio's investments, but enhanced the Portfolio's return
potential in ways that met our investment criteria. In general, the purchases we
made for the Portfolio during this period had a positive impact on performance
as the markets calmed in the fourth quarter.
 
For example, the Portfolio purchased the convertible securities of Amkor
Technologies, a semiconductor packaging company, when their securities were
trading in the high 40s. By the end of the year, they were trading in the low
90s. Another purchase the Portfolio made was the convertible securities of
PhyCor, a company that manages physicians and their practices. Unfortunately,
the clinics PhyCor organized performed below expectations and the performance of
the convertibles was weak after the Portfolio purchased them. Nevertheless, we
believe the company has good potential and may show stronger performance in
1999.
 
WHAT OTHER SIGNIFICANT ACTIONS DID YOU TAKE DURING THE REPORTING PERIOD?
Perhaps the most important decision was to stick to our disciplines, and not
take on risks that we felt were inappropriate for the Portfolio. The Portfolio
continued to hold or add to issues that we believed had strong upside potential
and sufficient downside protection.
 
WERE THERE OTHER SIGNIFICANT PURCHASES IN THE PORTFOLIO?
We purchased the preferred stock of Newell Financial Trust in the first quarter
of the year. In the wake of the market downturn that resulted in part from the
Asian crisis, we felt the securities were attractively priced and represented
good value. The company acquires major brands -- from ballpoint pens to
Rolodexes and household products -- and attempts to streamline their
manufacturing and distribution process. This "integration" process has been
highly successful and has helped the company's securities provide solid
performance for the Portfolio.
 
WHAT SECURITIES WERE SIGNIFICANT SALES FOR THE PORTFOLIO?
One convertible security we purchased for the Portfolio during 1998 was a bond
issued by Loews that was exchangeable into the common stock of Diamond Offshore
Drilling, an oil services company with exposure to deep-water drilling. Although
the Asian crisis and low oil prices generally had a negative impact on oil
services stocks in 1998, the bonds showed strong performance for a variety of
reasons.
 
First, Loews is an investment-grade issuer, which helped provide the downside
protection we look for in convertibles. Second, we purchased the bonds when
Diamond Offshore Drilling was down in price, which also lowered the price of the
bonds and gave the Portfolio more upside potential. Third, since oil companies
have largely tapped shallow reserves, whenever oil showed signs of recovery,
deep-water names tended to lead the rally. During October, we were able to take
advantage of Diamond Offshore Drilling common stock price gains and sell the
bonds at a substantial profit, which had a positive impact on the Portfolio's
performance.
 
WERE THERE OTHER SIGNIFICANT SALES DURING THE YEAR?
The Portfolio sold a number of securities during what we refer to as the
"stealth bear market" during the year. While the S&P 500 was climbing, several
smaller-capitalization stocks were experiencing corrections, and our careful
research helped the Portfolio get out of issues that faced potential problems
before they had a major impact on performance.
 
One example would be the Portfolio's holdings of Premier Technologies
convertible bonds, a company that was making strategic acquisitions in the
communications industry. Although they had rapid earnings growth, our analysis
showed that their cash flow was lagging their growth rate. Sensing potential
difficulties, we sold the Portfolio's Premier Technologies convertibles in the
second quarter of 1998. Shortly thereafter, the company missed a quarterly
earnings estimate and their stock and bond prices plummeted.
 
BEA Systems is a company that produces "middleware," or software used to
integrate the complex systems, software platforms, and applications used by
large enterprises.

WHAT WERE THE PORTFOLIO'S BEST-PERFORMING SECURITIES IN 1998?
We've already discussed most of them. In order of their contribution to the
Portfolio's performance, the top performers were Unisys, Time Warner, Newell
Financial Trust, and Loews/Diamond Offshore Drilling.
 
WHICH OF THE PORTFOLIO'S SECURITIES WERE WEAK PERFORMERS DURING THE YEAR?
The health care industry has wide representation in the convertible market and
has been hurt by a number of factors, including escalating costs and changes in
government policy. Integrated Health Services, a contract therapy provider,
faced difficulties in the health care industry and its securities also detracted
from the performance of the Portfolio.
 
WHAT WERE THE BEST DECISIONS YOU MADE FOR THE PORTFOLIO IN 1998?
If you look at the Portfolio's top performers and significant sales, you'll see
the advantages of our bottom-up investment disciplines and ongoing research. We
select securities one at a time, after careful analysis of their individual
merits from a quantitative and fundamental perspective. The convertible market
requires an analysis of both the stock and the convertible security to
understand how their shifting relationship is likely to impact performance. We
believe our vigilance helped us identify strong securities and spot potential
weaknesses -- both of which benefited the Portfolio in 1998.
 
Although we lagged the market when it rose at year-end, we still believe our
risk-averse approach to investing was beneficial for investors, particularly as
the markets become increasingly volatile. While securities that performed like
equities helped many portfolios in the latter part of the year, we were pleased
to have fewer of those securities in the Portfolio and thus maintain a lower
risk profile.
 
DOES THE PORTFOLIO CURRENTLY HAVE ANY SIGNIFICANTLY OVERWEIGHTED OR
UNDERWEIGHTED POSITIONS?
The Portfolio is currently overweighted in the real estate investment trust, or
REIT, sector. The securities the Portfolio owns have underperformed in a strong
market, but we believe they have attractive risk/reward profiles and will
continue to provide steady returns. The Portfolio sold some of its oil
exploration and oil services holdings in the first half of the year, but remains
overweighted in the energy sector. We believe that eventually the price of oil
will rise and the Portfolio's energy holdings will provide attractive
appreciation potential.
 
Currently, the Portfolio is underweighted in media, where rising stock prices
have caused convertible securities to have more of the downside of equities than
we prefer to see. While the Portfolio may have missed some opportunity in this
sector, we prefer to balance upside potential with a measure of downside
protection.
 
WHAT MAJOR RISKS WILL THE MARKETS FACE GOING FORWARD?
The period from July through October showed exactly the kinds of risks
convertible investors may face. During that period, we generally saw widening
spreads, low liquidity, and sinking prices. While that's a devastating
combination for any bond investor, convertible investors may face extra
vulnerability because the fate of the securities they own may be tied to the
performance of stocks that are experiencing greater volatility themselves.
That's why we believe our concentration on risk management has been positive for
the Portfolio, even if it meant lagging other portfolios in up markets.
 
WHAT'S YOUR OUTLOOK FOR THE FUTURE?
We believe the low prices the convertible security market saw in October may
have a positive impact on future performance. But we continue to view volatility
as a major concern and believe that careful security selection will be the key
to solid performance in the year ahead. Whatever the markets bring, we will
continue to focus on both risk and reward as the Portfolio seeks capital
appreciation together with current income.

MAINSTAY VP GOVERNMENT PORTFOLIO
 
1998 MARKET RECAP
- - During the first half of 1998, domestic bond markets experienced the lowest
  volatility in 15 years, but in the second half of the year, volatility was at
  a 15-year high.
- - Throughout 1998, the bond markets were influenced by a worldwide financial
  crisis, a budget surplus that reduced Treasury issuance, modest inflation, low
  unemployment, and falling commodity prices.
- - In the last four months of the year, the Federal Reserve Board moved to reduce
  interest rates three times.
- - In the second half of 1998, difficulties in Asia, Russia, and Brazil, along
  with the near failure of a leading hedge fund, resulted in a flight to quality
  that raised prices of high-quality, highly liquid securities, and reduced the
  yield on 30-year Treasury bonds to record lows.
 
1998 PORTFOLIO RECAP
- - For the 12 months ended 12/31/98, the MainStay VP Government Portfolio
  returned 9.00%.
- - The Portfolio benefited from a duration strategy that was long to neutral
  throughout the year.
- - The Portfolio's overweighted position in 30-year Treasuries helped the
  Portfolio benefit as the yield curve flattened in the second quarter and again
  in the second half of 1998.
- - Shifting the Portfolio's weighting in mortgage-backed bonds enhanced returns
  by avoiding prepayment risk in the first and third quarters and taking
  advantage of increasing investor demand for mortgage-backed bonds late in the
  year.
- - The Portfolio outperformed the average Lipper(1) Variable Products general
  U.S. government portfolio, which returned 8.07% for the year ended 12/31/98.
 
MANAGEMENT DISCUSSION AND ANALYSIS
Overall, 1998 was a year of extremes in the bond market, causing investors to
reevaluate risk at several levels. The first half of 1998 saw the lowest level
of volatility in 15 years, while the second half of the year reflected the
highest volatility in 15 years.
 
A variety of forces fueled the progress of the bond markets, including a budget
surplus that reduced Treasury issuance and tightened supply, and a flight to
quality in the third quarter of 1998 that dramatically increased demand for
government bonds. Fueled by financial problems in Asia, Russia, and Latin
America, and the near collapse of one of the world's largest hedge funds, the
rush to high-quality, highly liquid issues drove government bond prices higher
and reduced 30-year Treasury yields to record lows.
 
Meanwhile, modest inflation, low unemployment, and a strong U.S. dollar provided
a positive economic backdrop, but a worldwide financial crisis, along with
earnings disappointments at leading corporations caused wide swings in the stock
market, eroding investor confidence in the third quarter of 1998. In response,
the Federal Reserve Board moved to reduce interest rates three times in the
third and fourth quarters, helping to calm the markets, and bring liquidity back
to the marketplace.
 
Mortgage-backed securities had variable performance amid shifting interest rates
and prepayment concerns, but recovered strongly at the end of the fourth
quarter. Asset-backed securities generally showed positive performance,
particularly among highly rated, short-term issues, where the likelihood of
prepayment was low.
 
By year end, market prices reflected most of the variables that had a major
effect in 1998, including inflation expectations, Asian and emerging market
concerns, and anticipated action by the Federal Reserve Board.
 
HOW DID THE MAINSTAY VP GOVERNMENT PORTFOLIO PERFORM IN THIS MARKET ENVIRONMENT?
The MainStay VP Government Portfolio returned 9.00% for the year ended 12/31/98,
outperforming the average Lipper Variable Products general U.S. government
portfolio which returned 8.07% for the same period.
 
WHAT STRATEGIES DID THE PORTFOLIO USE TO ACHIEVE THIS PERFORMANCE?
We believe that duration was an important factor in determining the Portfolio's
performance. The Portfolio's strategy throughout the year was to remain long to
neutral. In the first half of the year, the Portfolio remained long as rates
headed lower and reduced duration as rates rallied, which had a positive impact
on performance. In the second half of the year, the Portfolio's performance
moved with the ebb and flow of the market, but its duration shortened in the
fourth quarter, which had a marginally negative impact on performance late in
the quarter. Overall, however, the Portfolio's duration strategy resulted in
positive performance.
 
                                       19
<PAGE>   20
 
The Portfolio's yield-curve strategy was also a positive contributor to
performance. The Portfolio remained overweighted in 30-year Treasuries, which
helped the Portfolio throughout the year, but particularly in the second and
fourth quarters, when yield spreads between the 2-year and 30-year Treasury
narrowed, flattening the yield curve.
 
WHAT IS THE OVERALL QUALITY OF THE SECURITIES IN THE PORTFOLIO'S INVESTMENT
PORTFOLIO?
The overall credit quality of the securities held by the Portfolio's investment
portfolio is Agency(2) which is better than AAA(3). The Portfolio's emphasis on
high quality proved beneficial when investors rushed to government bonds seeking
a haven of relative security when the stock market dropped nearly 20% in August.
The uncertainty surrounding emerging markets and hedge funds helped fuel the
interest in high-grade bonds, and the Portfolio was well positioned to take
advantage of investor preferences during this period.
 
HOW DID THE PORTFOLIO'S MORTGAGE-BACKED SECURITIES PERFORM?
Anticipating prepayments, the Portfolio entered the year underweighted in
high-coupon mortgage-backed securities, which was positive for performance. In
the second quarter, the Portfolio added bonds we believed would not be
interest-rate sensitive and managed to take some profits as the market rallied.
Unfortunately, a second wave of prepayments hurt the Portfolio's holdings and an
overweighted position detracted from performance in the second quarter.
 
In the third quarter, we reduced the Portfolio to an underweighted position in
mortgage-related bonds, which proved beneficial as interest rates fell and
prepayments continued. During the fourth quarter, the Portfolio had an
opportunity to purchase mortgage-backed bonds at distressed prices from hedge
funds that were forced to liquidate their holdings. This contributed positively
to performance as the Federal Reserve moved to lower interest rates, which
helped restore investor confidence, bring order to the markets, and increase
demand for mortgage-backed securities.
 
WERE THERE OTHER STRATEGIES THAT CONTRIBUTED POSITIVELY TO PERFORMANCE?
In the first half of the year, interest rates remained in a relatively narrow
range, so we used a variety of technical indicators to guide the Portfolio
between newer and older issues, which provided incremental gains.
 
Finding few opportunities elsewhere, the Portfolio was heavily weighted in
Treasury securities, which had a positive impact on performance throughout the
year, but particularly in the second half of 1998, when a drop in the stock
market, concerns over Asia, Russia, and Brazil, and problems with major hedge
funds caused investors to seek a "safe haven" in Treasury securities. The gains
during this period were exaggerated by the budget surplus, which decreased
Treasury issuance and limited supply at a time when demand for highly liquid
top-quality securities was extremely high.
 
WHAT OTHER INVESTMENTS DID THE PORTFOLIO HAVE?
The Portfolio also had relatively small allocations in agency securities,
asset-backed securities, unleveraged CMOs, and variable floating-rate notes. All
of these positions contributed positively to performance over the course of the
year. Among asset-backed securities, the Portfolio's concentration on
high-quality, shorter-term issues provided a measure of prepayment protection,
which was a positive factor. The Portfolio's asset-backed securities increased
its yield and provided AAA quality.
 
DID THE PORTFOLIO MAKE ANY MATERIAL SHIFTS IN ITS SECTOR ALLOCATIONS DURING THE
YEAR?
Over the course of the year, the largest shift was a decrease in Treasury
holdings and an increase in mortgage-backed securities. That change accelerated
in the fourth quarter, when hedge fund liquidations made it possible to purchase
mortgage-backed securities at what we believed to be very attractive prices. The
Portfolio took profits in Treasuries to purchase these securities, and both the
purchases and sales had a positive impact on performance.
 
WHAT IS YOUR OUTLOOK GOING FORWARD?
We believe that unless a major market shift occurs, the Federal Reserve is
likely to remain on hold for a while, though it may move to ease interest rates
further as the year unfolds. We continue to believe that diversification will be
important for an investor's overall allocation as was exhibited by the inverse
relationship between stocks and bonds in the second half of 1998. Within the
fixed-income market we believe value can be added along the yield curve as
reduced Treasury issuance and ongoing volatility continue to create
opportunities. We also anticipate reduced supply and higher demand for
mortgage-backed securities and believe the Portfolio is well positioned to take
advantage of any move in that direction. Whatever happens, the Portfolio will
continue to
                                       20

emphasize high-quality investments as we seek a high level of current income,
consistent with safety of principal.

MAINSTAY VP HIGH YIELD CORPORATE BOND PORTFOLIO
 
1998 MARKET RECAP
- - The development of the high-yield bond market in Europe added new
  diversification opportunities for high-yield investors.
- - The potential for deflation became a global theme that made it increasingly
  difficult for many high-yield issuers to meet earnings expectations.
- - Successive financial problems in Asia, Russia, and Latin America resulted in a
  flight to quality that greatly increased the premium investors required to
  assume additional risk.
- - As liquidity all but evaporated in the third quarter of 1998, lower-rated
  bonds traded at more attractive levels.
 
1998 PORTFOLIO RECAP
- - For the 12 months ended 12/31/98, the MainStay VP High Yield Corporate Bond
  Portfolio returned 2.66%.
- - The Portfolio began the year defensively positioned and underweighted in
  economically sensitive sectors.
- - In midyear, the Portfolio found opportunities among lower-rated issues as
  reduced liquidity lowered prices, but by year end, higher-rated issues offered
  more appealing default-adjusted spreads.
- - The Portfolio benefited from several bonds that were tendered away and from
  careful selection of securities with strong asset coverage.
- - The Portfolio outperformed the average Lipper(1) Variable Products high
  current yield portfolio, which returned 0.10% for the year-ended 12/31/98.
 
MANAGEMENT DISCUSSION AND ANALYSIS
As years go, 1998 was one of the most volatile in recent memory. Both the stock
and bond markets were affected by a number of forces that impacted high-yield
securities. While the stock market was dominated by large-cap growth stocks that
soared to new highs, many smaller companies that make up the high-yield bond
market suffered corrections.
 
A major theme that pervaded the markets in 1998 was the potential for global
deflation. With low inflation, prices remained relatively stable and in some
cases had to be reduced to promote sales. As a result, many corporations found
it increasingly difficult to meet earnings expectations. Since corporate
earnings are a primary factor influencing the high-yield market, any earnings
disappointments were met with quick, negative responses from investors,
underscoring the importance of careful research and credit analysis.
 
In the third quarter of 1998, financial problems in Asia, Russia, and Latin
America, declining commodity prices, and problems at a leading hedge fund,
caused a general flight to quality. Investors' appetite for risk would end
liquidity if the noninvestment grade market evaporated. As investors rushed to
purchase the largest and most liquid stocks and bonds, the high-yield bond
market experienced severe dislocations, with liquidity all but evaporating for
many lower-rated issuers. The resulting decrease in prices provided attractive
opportunities among lower-rated bonds. In the fourth quarter, the high-yield
market experienced a substantial recovery as the Federal Reserve Board made
successive moves to lower interest rates, which improved investor confidence.
 
During the year, a high-yield bond market emerged in developed European
economies, expanding the diversification opportunities for high-yield investors.
 
HOW DID THE MAINSTAY VP HIGH YIELD CORPORATE BOND PORTFOLIO PERFORM IN THIS
MARKET ENVIRONMENT?
The MainStay VP High Yield Corporate Bond Portfolio returned 2.66% for the year
ended 12/31/98, outperforming the average Lipper Variable Products high current
yield portfolio, which returned 0.10% for the same period.
 
WHY DID THE PORTFOLIO OUTPERFORM ITS PEERS?
A variety of positive developments contributed to the Portfolio's
outperformance. At the beginning of 1998, we had positioned the Portfolio
defensively, in light of the difficulties in Asia, which had taken a severe toll
on securities with foreign exposure in late 1997.
 
Throughout the year, telecommunications, which makes up a large portion of the
high-yield market, simply did not fit our investment disciplines. We believed
that many telecommunications issues were overpriced for the amount of risk they
involved. Our decision to underweight telecommunications in the Portfolio proved
beneficial, as the sector tended to underperform.
 
                                       22
<PAGE>   23
 
Of course, more important than where the Portfolio didn't invest was where it
did. Using our careful bottom-up security selection process, we individually
selected securities that we believed would overcompensate the Portfolio for the
risks it would have to assume. Using this process, we were drawn throughout 1998
to recession-resistant industries, such as media, health care, utilities, and
office properties, which had a positive impact on performance.
 
WHAT WERE SOME OF THE PORTFOLIO'S SIGNIFICANT PURCHASES DURING 1998?
One was United International Holdings, an international cable company, which we
purchased for the Portfolio in the third quarter. The Portfolio already owned
United International Holdings bonds and had done a considerable amount of
research on the company. The company tendered for the bonds we owned, but we
felt the new issue was overpriced when it originally came to market. During the
market setback in the third-quarter, however, the price of the new bonds dropped
to about seventy-five cents on the dollar, which we thought was attractive.
Accordingly, we made a substantial purchase, and the bonds were among the
Portfolio's top-performing securities in 1998.
 
Although the Portfolio did not emphasize telecommunications during the year,
another top-performing name was Centennial Cellular. During 1998, the company
was acquired and the bonds were tendered away, with a positive impact on
performance.
 
In the fourth quarter, the Portfolio also purchased Centaur Funding, a preferred
equity obligation of Airtouch Communications, a cellular phone company. The
bonds, which were rated BBB(2) reflected the superior value of higher-rated
bonds as the high-yield market recovered. They were trading at about a 50 basis
point advantage to bonds rated BB(3). From the day we purchased the bonds for
the Portfolio, they have been positive performers. As rumors began to circulate
that Airtouch Communications might be acquired by Bell Atlantic, they
contributed positively to performance.
 
Another bond the Portfolio purchased in the second half of the year was issued
by Highwoods Realty, a diversified commercial property REIT. The bonds were
relatively high quality and the Portfolio was able to purchase them at what we
believe was a very attractive price -- well below where the bonds were trading
earlier in the year. Although they haven't yet had any noticeable impact on
performance, we believe they will perform well in 1999.
 
WERE THERE OTHER SIGNIFICANT PURCHASES IN THE PORTFOLIO?
We also purchased Medaphis bonds for the Portfolio. Medaphis provides billing
services to doctors and develops software for patient scheduling and hospital
applications. Unfortunately, just after we purchased the bonds for the
Portfolio, the company missed its third-quarter earnings projections, which took
a toll on performance.
 
We took another careful look at the company to determine if it still fit our
process, and we believed there was very good asset value at Medaphis. The
company told us they planned an asset sale, and we added to the Portfolio's
position at much lower prices. They did make the sale, so by year-end, they were
flush with cash, had great liquidity, and their operating momentum appeared to
be improving. Although the bonds had a negative impact on the Portfolio's
performance in 1998, we believe they will do well going forward.
 
WHAT WERE SOME OF THE PORTFOLIO'S MORE SIGNIFICANT SALES?
Significant sales included Viacom, Loewen Group, and Vencor. The Portfolio's
Viacom holdings reached the Portfolio's price target as yield spreads tightened
in the first half of the year, so we sold the Portfolio's position at a profit.
 
Loewen Group is the world's second largest publicly held funeral service and
cemetery corporation in terms of revenues and assets. Through our research
process, we identified potential problems at the company and spoke to management
several times about them. The more we spoke with the company, the less secure we
became about their understanding of the underlying economies of their business.
Perceiving a risk that they would continue to miss earnings projections, we sold
the Portfolio's position. Although the sale price was lower than the original
purchase, subsequent performance proved that it was a positive decision for the
Portfolio.
 
We also purchased a new issue of Vencor, a nursing home operator, but decided
that a change in Medicare payment systems was likely to negatively impact the
company's business. As a result, we sold the position in July, which, like
Loewen Group, was positive for the Portfolio, since the Portfolio was able to
reinvest the assets in more productive securities.

<PAGE>   24
 
WHICH OF THE PORTFOLIO'S SECURITIES PROVIDED THE BEST PERFORMANCE IN 1998?
CD Radio is a company that plans to do for radio what satellite TV did for
television. We bought their bonds for the Portfolio in late 1997, but during
1998 two large investors, the Bass Family and Apollo Group, infused equity into
the company, lending credibility to their business plan. That strengthened the
performance of the bonds, which were the best-performing assets in the Portfolio
for the year.
 
WERE THERE OTHER STRONG PERFORMERS IN THE PORTFOLIO?
Yes. The Portfolio had excellent success with Hutchison Whampoa, another Hong
Kong conglomerate with diversified holdings in property development and
investment, ports and related services, retailing and manufacturing,
telecommunications and media, and infrastructure and energy. The company has
excellent asset coverage, high-quality bonds, and performed well for the
Portfolio.
 
Quest Diagnostics is a health care company whose bonds showed strong performance
in 1998, as the company continued to generate strong free cash flow, improving
credit statistics.
 
WHICH OF THE PORTFOLIO'S SECURITIES WERE POOR PERFORMERS IN 1998?
Northern Offshore is an oil services company whose bonds the Portfolio
purchased. Within just a few months of the purchase, declining oil prices caused
the company to not put a couple of their new rigs into service, which had a
negative impact on bond performance. We have cut back on the Portfolio's
position, but lost money on the sales.
 
Another loser was Entex Information Services, a company that distributes
computers and software and provides technology consulting to corporate clients.
Unfortunately, the company missed its earnings projections within two quarters
of issuing its bonds, which had a negative impact on the Portfolio's
performance. We believe the value of the consulting business alone would cover
the Portfolio's bond investments, and management has assured us that their
operating momentum is now moving in a more positive direction, so the Portfolio
continues to hold their securities.
 
We already mentioned Medaphis, which also detracted from the Portfolio's
performance in 1998.
 
WERE THERE ANY MAJOR SURPRISES DURING THE YEAR?
Perhaps the biggest surprise was how quickly the market reacted to potential
problems. Investors used to have a buffer period to discover negatives before
bond prices declined. But now, the market is becoming much more efficient at
pricing negative news. We purchased Extendicare Health Services bonds for the
Portfolio in late 1997, and early in 1998, we found that our research didn't
resemble what the company had told us to expect. Fortunately, the Portfolio was
able to sell those bonds at a profit. However, these windows of opportunity are
becoming shorter as demonstrated by Medaphis, whose bonds dropped sharply
immediately following their earnings warning.
 
IN WHICH SECTORS WAS THE PORTFOLIO UNDERWEIGHTED AND OVERWEIGHTED IN 1998?
The Portfolio was overweighted in health care, including Medaphis, Columbia/HCA
Healthcare, Magellan Health Services, Quest Diagnostics, and ICN
Pharmaceuticals. Electric utilities were also overweighted in the Portfolio,
with positive results from several of its holdings.
 
During the year, the Portfolio also overweighted office property REITs,
including Highwoods Realty and Crescent Real Estate Equities. With the exception
of Medaphis, all of these holdings had a positive impact on performance.
 
Although some of the Portfolio's biggest winners were telecommunications names,
the Portfolio benefited from its generally underweighted position in
telecommunications relative to the high-yield market as a whole.
 
WHAT IS THE OVERALL QUALITY OF THE SECURITIES IN THE PORTFOLIO'S INVESTMENT
PORTFOLIO?
As of year end, the overall credit quality of the securities held by the
Portfolio was B+(4) but during the third quarter, we found a number of
opportunities among lower-rated credits, which brought the quality of securities
held by the Portfolio down to B. In the fourth quarter, we found that
default-adjusted spreads were greater in higher-rated bonds, so we made several
purchases that improved overall quality of securities held by the Portfolio back
to B+.
 
WHAT IS A DEFAULT-ADJUSTED SPREAD?
The Portfolio seeks the greatest possible compensation for the level of risk it
assumes. At each quality-rating level, there is a historical rate of default.
When we subtract the default rate from the spread over comparable
 
                                       24
<PAGE>   25

 
Treasury securities, we obtain what we call the default-adjusted spread. We try
to emphasize securities with the widest spreads, after adjusting for the risk of
default. Of course, before we invest for the Portfolio, we also carefully
research the company, its asset coverage, free cash flow, and whether there is a
compelling reason to buy the bonds.
 
WHAT IS YOUR OUTLOOK GOING FORWARD?
We continue to believe that we are in the late stages of the credit cycle and
will remain alert to potential risks that may arise as a result. At year-end, we
found higher-rated bonds were offering higher compensation for their relative
risk than other securities, but we realize that as yield spreads shift, this
relationship is subject to change. We believe that any factors that influence
corporate earnings will continue to influence the high-yield bond market.
Whatever happens, we will continue to seek a diversified array of high-yield
securities with the potential to maximize current income for the Portfolio.

MAINSTAY VP INTERNATIONAL EQUITY PORTFOLIO
 
1998 MARKET RECAP
- - Global liquidity, led by the U.S. stock market, contributed to positive
  results in stock markets throughout most of Europe.
- - As European Monetary Union approached, European stocks benefited from
  increased merger and acquisition activity, moves by European central banks to
  lower interest rates, and strong consumer spending.
- - Deregulation in telecommunications and banking helped these sectors show
  strong performance, especially in European markets.
- - Financial problems in Asia, Russia, and Latin America caused a flight to
  quality, with equity investors seeking highly liquid securities and companies
  with consistent track records of steady earnings growth.
 
1998 PORTFOLIO RECAP
- - For the 12 months ended 12/31/98, the MainStay International Equity Portfolio
  returned 23.11%.
- - The Portfolio benefited from an overweighted position in European equities and
  from its underweighted position in Japanese stocks.
- - A focus on telecommunications, banking, and health-related stocks helped the
  Portfolio benefit from consumer, economic, and demographic trends.
- - The Portfolio outperformed the average Lipper(1) Variable Products
  international portfolio, which returned 13.26% for the year.
 
MANAGEMENT DISCUSSION AND ANALYSIS
As years go, 1998 was one of the most volatile in recent memory. International
equity markets started the year with investors focused on the Asian financial
crisis, which grew progressively worse as Japan slipped into recession. Over the
course of the year, problems in Russia and Latin America caused a general flight
to quality, with investors focusing on highly liquid securities, well-known
names, and consistent earnings generators.
 
The flight to quality was a positive for the European market, which showed
strong performance as European Monetary Union approached. Most European
countries continued to benefit from low inflation, strong merger and acquisition
activity, and moves by central banks to lower interest rates. The U.K., which
faced a recession in its manufacturing sector, was also forced to lower interest
rates, which had a positive effect on stock prices.
 
Japanese stocks benefited from a strengthening yen in the second half of the
year, but generally tended to underperform other international markets.
Australia and New Zealand suffered somewhat as commodity prices continued to
decline, and declining oil prices had a generally negative impact on energy
stocks around the world.
 
Among the best-performing sectors worldwide were telecommunications, which
benefited from technological advances and wide consumer appeal; banking, which
benefited from low inflation and lower interest rates; and health-related
stocks, which advanced with new products to assist an aging population.
 
HOW DID THE MAINSTAY VP INTERNATIONAL EQUITY PORTFOLIO PERFORM IN THIS MARKET
ENVIRONMENT?
Quite well. The MainStay VP International Equity Portfolio returned 23.11% for
the year ended 12/31/98, outperforming the average Lipper Variable Products
international portfolio, which returned 13.26%.
 
HOW DID THE PORTFOLIO MANAGE TO DO SO WELL?
The Portfolio uses a "country first" approach, seeking to identify the most
promising markets and invest in a wide array of companies in each target market.
This approach proved beneficial in 1998, as difficulties in Asia led the
Portfolio to maintain an underweighted position in Japanese equities. Overall,
Japanese stocks underperformed other global markets, despite currency gains in
the second half of the year. At the same time, the promise of European Monetary
Union led the Portfolio to take an overweighted position in Europe, which proved
highly beneficial for the Portfolio's performance. Finland was up 106.10% for
the year, Belgium 55.50%, Italy 42.20%, Spain 39.40%, France 31.40%, and Ireland
29.40%, all in local terms.
 
The Portfolio did not restrict its investments to countries that would
participate in European Monetary Union. Portfolio investments in non-EMU
countries, such as Sweden and the U.K., also had a positive impact on the
Portfolio's performance.
 
                                       26
<PAGE>   27
 
Although the Portfolio seeks to invest across a broad range of industries and
sectors, recognizing the strong potential in telecommunications, banking, and
health-related stocks, we emphasized these sectors in its 1998 investments,
which also contributed to outstanding performance.
 
WHAT WAS SO GOOD ABOUT TELECOMMUNICATIONS STOCKS?
Telecommunications stocks have benefited from strong growth and increasing
consumer demand. At the same time, many companies are taking advantage of new
technological advances to improve performance and deliver better service to
their customers. The Portfolio's largest holding and best-performing issue in
1998 was Nokia Oyj, a Finnish stock that we purchased in the third quarter. The
company has surpassed Motorola and Ericsson as the leading provider of mobile
phones and sold a record million handsets in a single month in 1998.
 
Another company that benefited from its telecommunications interests was
Mannesmann, which designs and manufactures a wide range of industrial products,
production machinery and assembly systems. The company also makes
telecommunication gears and equipment, which contributed significantly to
profits and earnings. The stock earned 110.10% in local terms for the year.
 
Deutsche Telekom was another of the Portfolio's strong performers. The company
owns and leases public telecommunications networks and has introduced new ADSL
technology, which promises faster transmission than existing ISDN lines.
Although telecommunications is growing more slowly in Germany than in the rest
of Europe, the stock contributed significantly to the Portfolio's positive
performance.
 
In July and August, we began to take profits in European and Japanese issues
that had reached the target values we had established for the Portfolio. We
invested some of the proceeds of these sales in telecommunications stocks in
Australia and New Zealand. One was an initial public offering in Cable &
Wireless Optus. The stock went public at 2.15 Australian dollars and by year-end
was trading at close to 4.00, which had a positive impact on the Portfolio's
performance.
 
WHY DID THE PORTFOLIO FOCUS ON THE BANKING AND FINANCIAL INDUSTRIES?
Financial stocks tend to perform well when interest rates decline. With the
severe market setbacks caused by problems in Asia, Russia, and Latin America, we
believed that central banks would be likely to lower interest rates to help
corporations cope with pressures to increase earnings in a low-inflation
environment. In the third and fourth quarter, the Federal Reserve Bank lowered
U.S. interest rates three times, and several European banks lowered rates
throughout the year, which helped stimulate corporate growth and make borrowing
more affordable. Since banks profit when borrowing increases, the results were
positive for the banking industry.
 
One of the Portfolio's successful investments was Allied Irish Banks, which was
up 76.90% in local terms for the year. The company provides a full range of
banking services through over 319 offices in Ireland, 82 branches in Northern
Ireland, and 37 offices in the U.K. It also operates over 200 branches in the
United States through its wholly-owned subsidiary, First Maryland Bancorp. With
the inception of the single currency throughout core Europe, we believe
financial institutions will look to establish themselves as a European force,
and we believe Allied Irish Banks has the experience and potential to do so.
 
Another financial services stock that showed positive performance during the
year was ING Groep. The company is headquartered in the Netherlands and has
global offices that provide commercial, savings, and investment banking, and
property and commercial insurance. The company was hurt in the third quarter by
its emerging market trading, but still returned 44.80% in local terms for the 12
months ended 12/31/98.
 
HOW DID THE PORTFOLIO BENEFIT FROM HEALTH-RELATED STOCKS?
Health-related sectors were stimulated by advances at several pharmaceutical
companies that capitalized on the aging population. Some of the biggest and best
pharmaceutical names are located in Europe, and the Portfolio sought to take
advantage of the positive trends in this sector. Other companies benefited from
the move toward natural foods, herbal remedies, and other health and
fitness-related trends.
 
The Portfolio owned the stock of Novartis, a large pharmaceutical company that
emerged from the combination of Sandoz and Ciba Geigy. As the price of the stock
rose, we decided to take profits from the Portfolio's Novartis shares and invest
them in the stock of Schering, a German pharmaceutical company specializing in
diagnostics, fertility control, hormone therapy, and dermatology. We believed
that Schering represented better value. Although neither stock was a stellar
performer, both Novartis and Schering provided positive returns for the
Portfolio in 1998.
 
                                       27
<PAGE>   28
 
Although the Portfolio tended to underweight Japanese stocks, it did own names
that had broad exposure to world markets. One of these was Yamanouchi
Pharmaceutical, which was up 30.00% in local terms for the year. While few
people have ever heard the name Yamanouchi Pharmaceutical, almost everyone is
familiar with one of their leading products, Pepcid AC. The company also has a
number of drugs that may provide substantial earnings growth over time,
including medications for high cholesterol, hepatitis C, and diabetes. The stock
reflected the Portfolio's concentration in the health-related sector and
provided strong relative value in a Japanese stock market that declined 8.90% in
local terms in 1998.
 
WHICH OTHER MARKETS WERE WEAK PERFORMERS FOR THE PORTFOLIO IN 1998?
New Zealand was the worst market, declining 14.90% in local terms for the year.
While Australian stocks advanced an otherwise respectable 12.70%, that figure
was substantially below the returns available in the Portfolio's best performing
European markets.
 
DID THE PORTFOLIO OWN STOCKS IN OTHER SECTORS THAT SHOWED STRONG PERFORMANCE IN
1998?
Yes. The Portfolio owned the stock of CRH, an Irish company that manufactures
cement, concrete products, and building materials. With operations in 12
countries, including Ireland, Spain, Germany, and the Netherlands, the company
is well positioned to take advantage of government spending throughout Europe to
improve infrastructure. Although cement may seem like a dull industry, expanding
and improving Europe's infrastructure is presenting growth opportunities for the
company, which was a positive contributor to the Portfolio's performance in
1998.
 
Another positive contributor to the Portfolio's performance was Volkswagen, the
car and truck manufacturer. The company expects double-digit growth in its North
American car sales in 1999, based on the introduction of its new Beetle. The
stock was up 34.20% in local terms for the year.
 
WHICH STOCKS DIDN'T DO WELL IN 1998?
The Portfolio owned a number of stocks that underperformed. One was Royal Dutch
Petroleum, which suffered from the substantial decline in the price of oil and
declined 16.00% in local terms for the year. As of year-end, we believed the
company represented good value and may perform well if and when oil prices turn
around. In fact, we're hoping to add to the Portfolio's position in this stock
to take advantage of its broad-based energy exposure -- from exploration and
drilling to final processing, delivery, and marketing.
 
Another stock that underperformed was Volvo. We added the stock to the portfolio
in September because we felt Sweden was a desirable market, autos were a solid
industry, and Volvo had strong fundamentals and international breadth, with 80%
of its sales outside of Sweden. Given the merger of Daimler Benz and Chrysler,
we believe that Volvo may be the next acquisition in the auto industry. But the
stock did not perform well in the few months the Portfolio owned it in 1998.
 
Finally, Nestle, the Swiss cocoa and consumer products company, was a
substantial underperformer. Although the company has solid fundamentals, a good
growth plan, and is involved in the growing market for nutritious foods, the
stock was too defensive to gain investor attention with the boom in
telecommunications and technology stocks.
 
WERE THERE ANY SIGNIFICANT SALES YOU MADE FOR THE PORTFOLIO IN 1998?
In Japan, we recognized the difficulties the financial industry was facing and
decided to sell several of the Portfolio's financial holdings, including
Sumitomo Bank. The sale was positive for the Portfolio, since we were able to
invest the assets elsewhere for more productive returns.
 
Most of the Portfolio's sales were designed to narrow its focus from 300
securities to about 215 at the end of the year -- and improve its positioning in
industries we felt had the strongest potential in individual countries. Many of
the sales that were part of this repositioning had only modest impact on
performance, though in most cases, the impact was positive.
 
WERE THERE OTHER SHIFTS IN THE MAKEUP OF THE PORTFOLIO?
Yes. While we retained about the same weighting in Europe, in the third quarter
of 1998, we shifted the Portfolio's focus from central European countries to
take in more peripheral European nations, such as Ireland, Finland, and Sweden.
With names like Allied Irish Banks and Nokia Oyj each of these additions had a
positive impact on performance.

WHAT WAS THE EFFECT OF CURRENCY MOVEMENTS ON THE PORTFOLIO IN 1998?
Generally speaking, the Portfolio had positive results from its currency
exposure. European currencies strengthened about 7.6% against the U.S. dollar
over the course of the year, which had a positive effect on total return
performance.
 
In the second half of 1998, European currencies weakened against the yen, and
the Portfolio participated in the yen's advance through the forwards market,
with a proxy hedge of European currency exposure. The trade was a contrarian
move that reflected our belief that negative sentiment about the yen, as well as
euphoria over the new European currency, the Euro, were both excessive. As the
yen strengthened, the hedge contributed positively to the Portfolio's
performance. The Portfolio also had direct exposure to the yen through its
weighting in Japanese equities, which strengthened the otherwise weak returns
from Japanese stocks in the second half of the year.
 
Commodity-linked currencies, particularly the Canadian, Australian, and New
Zealand dollar, all suffered from the general commodity weakness in 1998. Each
of these currencies declined about 7% relative to the U.S. dollar, which had a
negative impact on the Portfolio's performance.
 
IF YOU COULD RELIVE 1998, WHAT WOULD YOU HAVE DONE DIFFERENTLY?
In hindsight, the Portfolio would have benefited by being longer in yen-based
securities during the second half of the year. The Portfolio also might have
benefited by being in Hong Kong and Singapore in the second half of the year,
since they were both very strong. While the Portfolio might have missed some
opportunities there, we feel that the decisions we made for the Portfolio were
positive ones, and they were reflected in the Portfolio's performance relative
to its peers.
 
AS OF YEAR-END, WHERE WAS THE PORTFOLIO OVERWEIGHTED AND UNDERWEIGHTED?
At year-end, the Portfolio was overweighted in Finland, Belgium, Spain, Ireland,
Portugal, Sweden, New Zealand, and Australia. It was neutral in Germany and
underweighted in France and Switzerland. As we noted earlier, the Portfolio is
heavily underweighted in Japan.
 
WHAT RISKS DO YOU SEE AHEAD FOR INVESTORS?
The problems we saw this year represent real risks going forward. Emerging
markets, by their very nature, are relatively fragile and subject to forces that
can make them highly volatile. Brazil's economic difficulties are not happening
in a vacuum. They could have implications for other countries, such as Spain and
Portugal, which have economic, cultural, and language ties with Brazil. While we
believe that Europe should remain strong, the effects of European Monetary Union
are as yet untested. So we will continue to monitor developments in both
participating and nonparticipating European countries.
 
WHAT IS YOUR OUTLOOK FOR THE FUTURE?
We believe that Europe is likely to benefit from additional mergers and
acquisitions as monetary union gets underway. As long as interest rates and
inflation remain low, economic growth should continue to expand in both core and
peripheral European nations. In light of recent global economic setbacks,
however, we may position the Portfolio more defensively in the months ahead.
 
Generally speaking, we like the industries in which the Portfolio is
concentrated. Telecommunications should continue to benefit from advancing
technology and high consumer demand. Health-related companies should continue to
find opportunities as the population ages. While favorable forces have helped
banks and financial services, we recognize that that could change at any time.
Whatever happens, we will seek to identify countries and companies that we
believe may provide long-term growth of capital commensurate with an acceptable
level of risk.

MAINSTAY VP TOTAL RETURN PORTFOLIO
 
1998 MARKET RECAP
- - The U.S. stock market was highly volatile throughout 1998, but provided
  double-digit returns for the fourth year in a row in a growth-oriented
  environment marked by low inflation and declining interest rates.
- - Difficulties in Asia, Russia, and Latin America generally caused a flight to
  quality in both the stock and bond markets, with many investors seeking highly
  liquid securities and stocks of companies with steady earnings growth.
- - Technology and pharmaceutical stocks generally showed strong performance,
  while cyclical, energy, and commodity-related stocks tended to underperform.
- - Long-term Treasury securities showed strong performance throughout the year,
  while corporate bonds suffered from earnings disappointments and
  mortgage-backed securities faced prepayment risk through much of the year.
 
1998 PORTFOLIO RECAP
- - For the 12 months ended 12/31/98, the MainStay VP Total Return Portfolio
  returned 27.13%.
- - The Portfolio benefited from careful stock selection among
  large-capitalization companies in technology, pharmaceuticals, and consumer
  staples and by reducing positions in problem sectors such as energy.
- - The Portfolio benefited from a long to neutral duration throughout the year
  and from being overweighted in 30-year Treasuries when the yield curve
  flattened.
- - The Portfolio alternated between an underweighted and overweighted position in
  mortgage-backed securities, which generally proved beneficial.
- - The Portfolio outperformed the average Lipper(1) Variable Products balanced
  portfolio, which returned 14.79% for the year.
 
MANAGEMENT DISCUSSION AND ANALYSIS
As years go, 1998 was one of the most volatile in recent memory. Despite its ups
and downs, however, the S&P 500 Index(2) closed the year with a 28.58% gain,
making 1998 the fourth year in a row domestic stocks in general have returned
more than 20.00%.
 
With financial problems in Asia, Russia, and Latin America, declining oil
prices, and weaknesses in other commodities, many investors sought refuge in
stocks they felt were least likely to be affected by these difficulties. Many
investors focused on large-capitalization growth stocks that appeared to have
steady and predictable earnings prospects, with particular attention given to
technology and pharmaceutical issues. Purely domestic issues continued to do
well, while oil and commodity-related stocks tended to show poor performance.
 
Declining interest rates improved earnings prospects for many companies in the
latter half of the year, and calm inflation also helped strengthen the stock
market's advance. These same forces combined to make 1998 a year of extremes in
the bond market. The first half of the year saw the lowest level of volatility
in 15 years, while the second half of the year reflected the highest volatility
in 15 years.
 
A Federal budget surplus reduced Treasury issuance and tightened supply, while
the flight to quality in the third quarter of 1998 dramatically increased demand
for government bonds. With emerging market problems prompting the near collapse
of one of the world's largest hedge funds, the rush to high-quality, highly
liquid issues drove government bond prices higher and reduced yields on 30-year
Treasury bonds to record lows. Corporate bonds generally suffered from earnings
disappointments and weak demand as the stock market offered much higher return
potential. Mortgage-backed securities showed mixed performance, with prepayments
reducing returns in the first three quarters and stronger performance in the
fourth quarter of 1998, as the Federal Reserve Board's move to ease interest
rates helped stabilize the bond markets. Asset-backed securities generally
showed positive performance, particularly among highly rated, short-term issues,
where the likelihood of prepayment was low.
 
HOW DID THE MAINSTAY VP TOTAL RETURN PORTFOLIO PERFORM IN THIS MARKET
ENVIRONMENT?
Quite well. The MainStay VP Total Return Portfolio returned 27.13% for the
year-ended, outperforming the average Lipper Variable Products balanced
portfolio, which returned 14.79% for the year.
 
HOW DID THE PORTFOLIO MANAGE TO DO SO WELL?
A number of factors contributed positively to the Portfolio's performance, but
we believe the most important factor was sticking to our strict investment
disciplines. In the stock portion of the Portfolio, we generally seek companies
with strong growth prospects, considering such factors as steady growth in
revenues, accelerating
 
                                       31
<PAGE>   32
 
earnings, and increasing earnings per share. During the volatile market
environment in 1998, the Portfolio concentrated on large-capitalization issues,
which were among the stocks investors favored when problems in foreign markets
caused a flight to quality in both the stock and bond markets. We also reduced
the Portfolio's positions in sectors we felt were weak, such as oil and energy.
By concentrating on winners and largely avoiding losers, the Portfolio had an
excellent year.
 
In the bond portion of the Portfolio, we benefited from a long to neutral
duration strategy throughout the year, from being overweighted in 30-year
Treasuries as yield spreads tightened, and from being underweighted in
mortgage-backed securities when we believed the prepayment risk was high.
 
WHICH SECTORS CONTRIBUTED MOST STRONGLY TO THE PORTFOLIO'S STOCK PERFORMANCE?
We don't select sectors. Instead, we choose stocks for the Portfolio based on
their individual merits after extensive quantitative analysis and fundamental
research. As a result of the Portfolio's selection process, however, we found a
number of technology stocks that we believed had strong growth potential and
they contributed to the Portfolio's significant outperformance. Despite various
setbacks throughout the year, the Portfolio remained overweighted in technology
stocks through all four quarters.
 
Pharmaceutical stocks also had an excellent year, and the Portfolio had a number
of holdings that did well. New drug introductions, direct-to-consumer
advertising, and a long pipeline of FDA-approved drugs awaiting release helped
advance the sector as a whole.
 
Consumer staples as a group showed relatively weak performance in 1998, but our
stock selection process positioned the Portfolio in relatively defensive, purely
domestic companies, such as supermarkets, which performed well at a time when
the market seemed to prefer stable growth and relatively predictable earnings.
As a group, supermarkets are benefiting from consolidation, which is helping
improve margins and profits.
 
CAN YOU GIVE SOME EXAMPLES OF TECHNOLOGY STOCKS THAT DID WELL?
Certainly. Lucent Technologies was the Portfolio's best-performing stock in 1998
and also its largest equity holding. The company has done exceedingly well, with
the value of the Portfolio's position more than tripling during the year. Cisco
Systems is another technology stock that showed outstanding performance, with an
increase of 149% in 1998.
 
In January, the Portfolio purchased EMC, a leader in corporate data storage
systems, hardware, and software. We believed the company had excellent
potential, based on increasing dominance in its market sector and rapidly
accelerating earnings. The Portfolio's position almost doubled in value during
the year.
 
Compuware is a computer software company that was also among the Portfolio's
best performing stocks, and it more than doubled in value during the year.
 
DID ALL OF THE PORTFOLIO'S TECHNOLOGY STOCKS DO THAT WELL?
No. Computer Associates International showed relatively poor performance when
the company's management team lowered its earnings estimates and announced that
it might have difficulty closing large contracts.
 
WHAT ABOUT PHARMACEUTICAL STOCKS?
Given the positive fundamentals in the pharmaceutical industry and the high unit
volume growth in a low inflationary environment, pharmaceuticals were generally
excellent performers. Although we increased the Portfolio's position in Pfizer,
our timing could have been better. In the first half of the year, many investors
were selling the stock to take profits after the release of Viagra. During the
year, we also increased the Portfolio's position in Merck, a major drug company
profiting from successful products such as Pepcid AC, Propecia, and many others.
 
Other positive performers among drug stocks included Eli Lilly, a stock the
Portfolio has held for some time, and Schering-Plough. Schering-Plough's
Claritin product for allergy sufferers helped sales, earnings, and stock
performance.
 
DID THE PORTFOLIO REMAIN OVERWEIGHTED IN FINANCIAL STOCKS IN 1998?
No. Over the course of the year, we decreased the Portfolio's weighting in
financial stocks for a number of reasons. First, we believed that growth was
slowing in the financial sector. Second, the huge mergers in the financial
industry produced companies that were more difficult to analyze and evaluate.
 
                                       32
<PAGE>   33
 
The NationsBank merger with BankAmerica is a good example. The combination added
to the company's financial risk because BankAmerica was invested in a hedge fund
when the market had just suffered a major setback as a result of the problems at
Long Term Capital. Since the stock no longer fit the Portfolio's growth criteria
and risk profile, we cut back on the Portfolio's position, which had a slightly
negative impact. Although our decision to sell helped reduce portfolio risk, the
stock's subsequent performance suggested that the Portfolio would have been
rewarded for a more patient outlook.
 
Travelers Group and Citicorp joined to form Citigroup during the year, which
reduced our confidence in the company, as management faced a substantial
reorganization in an uncertain financial environment. As a result, we cut back
on the Portfolio's holdings in the summer, which was not the best time to sell,
so the transaction had a negative impact on performance.
 
WHAT WERE SOME OF THE MAJOR EQUITY PURCHASES THE PORTFOLIO MADE DURING THE YEAR?
In addition to those already mentioned, the Portfolio purchased Fred Meyer, a
large supermarket chain. We liked the company's fundamentals and believed it
might benefit from consolidation in the supermarket industry, which happened
when the company announced that it would be acquired by Kroger, another of the
Portfolio's investments. By the end of the year, Fred Meyer stock had increased
by about 50% from the Portfolio's purchase price.
 
In the first quarter, the Portfolio purchased the common stock of
Colgate-Palmolive. The company has shown stable growth and was having success
with its new Total toothpaste. Despite the company's international exposure, we
believed it could handle any difficulties the market might generate. For the
year, the stock was up 28%, which was in line with the S&P 500 Index.
 
As new money came into the Portfolio over the course of the year, we used much
of it to add to the Portfolio's most successful positions, including Lucent
Technologies, Cisco Systems, EMC, and others. So our buying strategy paralleled
our investment strategy of sticking with the winners in the investment
portfolio.
 
WERE ALL OF THE PORTFOLIO'S STOCK PURCHASES EQUALLY SUCCESSFUL?
No. We purchased HBO, a leading provider of health care software systems, during
the second quarter of 1998. The company looked attractive given its size, market
share, and growth rate. But shortly after we purchased the stock, the company
announced an acquisition that the market didn't like. Next, they decided to
merge with McKessen, a leading drug distributor. But miscommunication about the
merger caused the stock to substantially underperform the market. Although the
investment provided a positive return, it was substantially lower than other
holdings, and on a relative basis, had a negative impact on performance.
 
YOU MENTIONED SOME FINANCIAL STOCK SALES. WHAT OTHER STOCKS DID THE PORTFOLIO
SELL DURING 1998?
Perhaps the Portfolio's most significant stock sales were in the energy sector.
With declining oil prices and weakening prospects for exploration, drilling, and
oil services, we sold the Portfolio's positions in Diamond Offshore Drilling,
Halliburton, and ENSCO International. Since the performance of energy service
stocks was generally negative in 1998, we viewed the timing of the sales as
positive for the Portfolio, even though the Portfolio lost money on each of
these transactions. The wisdom of reallocating the assets was further
underscored as oil prices continued to decline.
 
We also sold the Portfolio's holdings of toy maker Mattel during the first half
of the year as fundamentals deteriorated and Barbie sales declined. We were
pleased to get out at a gain over the Portfolio's original purchase price,
although the Portfolio had a slightly negative return on the stock in 1998.
Later developments at the company underscored the wisdom of this sale.
 
DID THE PORTFOLIO MAKE OTHER SIGNIFICANT STOCK SALES?
Yes. The Portfolio sold its investments in Tenet Healthcare and United
Healthcare, both of which saw decelerating earnings growth rates. Tenet
Healthcare is a large hospital chain that missed its earnings projections.
United Healthcare suffered from rising medical costs and an inability to
smoothly integrate recent acquisitions. Although both stocks declined after we
sold the Portfolio's holdings, United Healthcare has since recovered a bit.
Nevertheless, we believe the sales were positive for the Portfolio by allowing
us to put the assets to better use elsewhere.
 
Adaptec is a technology company we sold at a loss after the Asian crisis slowed
earnings, which undercut the Portfolio's fundamental reasons for owning the
stock. The Portfolio sold the stock in the low twenties, and the price continued
to decline even further throughout most of the year.
 
                                       33
<PAGE>   34
 
Hewlett-Packard was a long-standing position in the Portfolio that simply failed
to live up to earnings expectations. The Portfolio sold the stock at a huge gain
over the Portfolio's original cost, but at a slight loss for the year.
 
WHICH STOCKS WERE THE PORTFOLIO'S WORST PERFORMERS IN 1998?
By far the worst stock was Cendant, which was plagued by news of accounting
irregularities at CUC International prior to its merger with HFS in late 1997.
The stock, which was a major holding, was down nearly 44% for the year. The
Portfolio continues to own the stock and believes the market has overpenalized
the company, which is generating $1.5 billion of free cash flow. But there's no
question that the company's reputation has been tarnished.
 
Other poor performers included HEALTHSOUTH, a nationwide rehabilitation and
outpatient surgical provider, which surprised the market by missing earnings
projections and preannouncing that problems would continue until 1999. Conseco
is an insurance company that acquired Green Tree Financial and suffered from
negative perceptions of its top management by many investors. Despite these and
other negative performers, the stock portion of the Portfolio was still able to
outperform the market by a substantial margin.
 
WHAT FACTORS CONTRIBUTED SIGNIFICANTLY TO BOND PERFORMANCE IN THE PORTFOLIO?
We believe that duration is among the most important factors determining bond
fund performance and our strategy throughout the year was to remain long to
neutral. In the first half of the year, the Portfolio remained neutral as rates
headed higher and extended duration as rates rallied, which had a positive
impact on performance. In the second half, we shifted the Portfolio's duration
with the ebb and flow of the market, but shortened in the fourth quarter, which
had a negative impact on performance. Overall, however, our duration strategy
was positive for the Portfolio.
 
Our yield-curve strategy was also a positive contributor to performance. We
remained overweighted in 30-year Treasuries, which helped the Portfolio
throughout the year, but particularly in the second and fourth quarters, when
yield spreads narrowed, flattening the yield curve.
 
WERE THERE OTHER STRATEGIES THAT CONTRIBUTED POSITIVELY TO PERFORMANCE?
In the first half of the year, interest rates remained in a relatively narrow
range, so we used a variety of technical indicators to guide the Portfolio
between newer and older issues, which provided slight incremental gains.
 
Finding few opportunities elsewhere, the Portfolio was heavily weighted in
Treasury securities, which had a positive impact on performance throughout the
year, but particularly in the second half of 1998, when a drop in the stock
market, concerns over Asia, Russia, and Brazil, and problems with major hedge
funds caused many investors to seek a "safe haven" in Treasury securities. The
gains during this period were exaggerated by the budget surplus, which decreased
Treasury issuance and limited supply at a time when demand for highly liquid
top-quality securities was extremely high.
 
DOES THE PORTFOLIO CONCENTRATE ON HIGH-QUALITY DEBT SECURITIES?
Yes it does. The Portfolio's income portfolio emphasized U.S. government bonds,
high-quality mortgage-backed and asset-backed securities, and high-grade
corporate issues.
 
HOW DID THE PORTFOLIO'S MORTGAGE-BACKED SECURITIES PERFORM?
Anticipating prepayments, the Portfolio entered the year underweighted in
high-coupon mortgage-backed securities, which was positive for performance. In
the second quarter, the Portfolio purchased bonds we believed would not be
interest-rate sensitive and managed to take some profits for the Portfolio as
the market rallied. Unfortunately, a second wave of prepayments hurt the
Portfolio's holdings and an overweighted position detracted from performance in
the second quarter.
 
In the third quarter, we reduced the Portfolio's bond holdings to an
underweighted position in mortgage-related bonds, which proved beneficial as
interest rates fell and prepayments continued. During the fourth quarter, the
Portfolio had an opportunity to purchase mortgage-backed bonds at distressed
prices from hedge funds that were forced to liquidate their holdings. This
contributed positively to performance as the Federal Reserve moved to lower
interest rates, which helped restore investor confidence, bring order to the
markets, and increase demand for mortgage-backed securities.
 
                                       34
<PAGE>   35
 
WHAT OTHER INCOME INVESTMENTS DID THE PORTFOLIO HAVE?
The Portfolio's corporate bonds had suffered a severe setback in the fourth
quarter of 1997 and given the impact of the Asian crisis, corporate spreads
widened substantially in the first quarter of 1998. We increased the Portfolio's
corporate exposure in the second quarter, seeking high-quality domestic issues
with minimal Asian exposure. With low volatility and the calm before the storm,
the contribution to performance was minimal for the second quarter.
 
In the second half of 1998, the Portfolio focused primarily on what we believed
to be capable media companies, utilities, retailers, and regional banks. But
with the financial problems in Russia and Brazil and difficulties at major hedge
funds, the corporate bond market generally faced a substantial setback. New
issuance all but stopped in the third quarter, and despite strong growth in
America's Gross Domestic Product, corporate bonds provided their worst
performance in a decade. Although the Portfolio was positioned in high-quality,
highly liquid issues and in some of the top-performing sectors, the overall
movement of the corporate market had a negative impact on performance.
 
The Portfolio also had relatively small allocations in agency securities,
asset-backed securities, CMOs, and variable floating-rate notes. All of these
securities contributed positively to performance over the course of the year,
but there were few if any remarkable events in any of these markets. Among
asset-backed securities, the Portfolio's concentration on high-quality,
shorter-term issues provided a measure of prepayment protection, which was a
positive factor. The Portfolio's asset-backed securities increased its yield and
added value during the flight to quality.
 
DID THE PORTFOLIO MAKE ANY DRAMATIC SHIFTS IN ITS BOND SECTOR ALLOCATIONS DURING
THE YEAR?
As we noted, adding corporate bonds in the second quarter did not work in the
Portfolio's favor. Over the course of the year, there was an increase in
mortgage-backed securities. That change accelerated in the fourth quarter, when
hedge fund liquidations made it possible to purchase mortgage-backed securities
at what we believed to be very attractive prices. The Portfolio took profits in
Treasuries to purchase these securities, and both the purchases and sales had a
positive impact on performance.
 
WHAT IS YOUR OUTLOOK GOING FORWARD?
We continue to view the markets as highly volatile and generally unpredictable.
So instead of trying to time our investments or dodge and weave with the market,
we will continue to select stocks we believe have strong growth characteristics,
solid performance records, and reasons to perform well in the future. In the
bond markets, we believe that unless a major market shift occurs, the Federal
Reserve is not likely to change interest rates for a while, though it may move
to ease interest rates further as the new year unfolds.
 
We continue to believe that diversification will be important for investors and
view the mix of stocks and bonds in the MainStay VP Total Return Portfolio as an
excellent way to spread risk while seeking high total-return potential. As long
as volatility continues, we believe investors will seek stocks with a history of
steady growth and have positioned the Portfolio's stock investments accordingly.
At year-end, we anticipated reduced supply and higher demand for mortgage-backed
securities and had overweighted these bonds in the income portion of the
Portfolio. Whatever happens, we will continue to seek to realize current income
consistent with reasonable opportunity for future growth of capital and income.

MAINSTAY VP VALUE PORTFOLIO
 
1998 MARKET RECAP
- - In 1998, the U.S. stock market provided double-digit returns for the fourth
  consecutive year, with advances dominated by large-capitalization growth
  stocks in technology and pharmaceuticals.
- - As the Asian financial crisis unfolded, low inflation, declining interest
  rates, and falling commodity prices had a negative impact on economically
  sensitive value sectors.
- - Amid extreme volatility in the equity markets, many investors virtually
  ignored traditional value measures such as low price-to-earnings ratios and
  instead sought refuge in the market's largest and most familiar names, with
  little regard for valuation.
- - Although value stocks traditionally outperform in declining markets, investors
  continued to focus on growth investments as many stock prices fell in the
  third quarter of 1998.
- - A spirit of confidence by many investors was reflected in the high prices of
  several Internet stocks with little history and virtually no earnings.
 
1998 PORTFOLIO RECAP
- - For the 12 months ended 12/31/98, the MainStay VP Value Portfolio returned -
  4.14%.
- - The Portfolio maintained its strict deep-value disciplines throughout 1998,
  despite the preference by many investors in the market for
  large-capitalization growth stocks.
- - The Portfolio benefited from an overweighted position in electric utilities,
  which provided significant positive returns, but was hurt by energy
  investments, which suffered from declining oil prices.
- - Purchasing financial services stocks after the market correction had a
  positive impact on performance, while certain retail and sporting goods stock
  purchases based on restructuring potential had a definite negative impact on
  the Portfolio in 1998.
- - The Portfolio underperformed the average Lipper(1) Variable Products growth
  and income portfolio, which returned 16.37% for the year.
 
MANAGEMENT DISCUSSION AND ANALYSIS
As years go, 1998 was one of the most volatile in recent memory. Despite its ups
and downs, however, the S&P 500 Index(2) closed the year with a 28.58% gain,
making 1998 the fourth consecutive year domestic stocks in general have returned
more than 20%. About two-thirds of the market's gains, however, occurred in the
25 largest issues. Severe corrections among smaller-capitalization stocks were
largely overshadowed by tremendous gains in large technology and pharmaceutical
stocks.
 
As the Asian crisis unfolded, low inflation, declining interest rates, and
falling commodity prices helped focus the attention of many investors on growth
stocks and had a negative impact on economically sensitive value sectors.
Extreme market volatility surrounding problems in Russia and Latin America
caused a general flight to quality, with many investors seeking a "safe haven"
in long-term U.S. government bonds and many of the stock market's largest and
most familiar names.
 
Throughout the year, many investors seemed to ignore traditional value measures,
preferring a "bigger is better" approach, regardless of cost or
price-to-earnings ratios. As a result, value stocks, which traditionally
outperform in declining markets, severely underperformed when the market tumbled
almost 20% at the end of August. Many smaller deep-value stocks experienced
their worst relative performance since the decade began.
 
In addition to ignoring traditional valuation criteria, many investors showed
enthusiasm for Internet stocks. Many of these issues had little history and
virtually no earnings, yet soared to record high prices, attracting a level of
attention that was reminiscent of biotechnology stocks in the early 1990s.
 
HOW DID THE MAINSTAY VP VALUE PORTFOLIO PERFORM IN THIS MARKET ENVIRONMENT?
The MainStay VP Value Portfolio returned - 4.14% for the year-ended 12/31/98,
underperforming the average Lipper Variable Products growth and income
portfolio, which returned 16.37% for the same year.
 
WHY DID THE PORTFOLIO UNDERPERFORM ITS PEERS?
There were a variety of reasons, but the most significant ones have to do with
our value disciplines and the category to which the Portfolio was compared. By
virtually every measure, 1998 was a year for large-capitalization growth stocks.
Our value disciplines usually lead us to invest in smaller-capitalization value
names, which were among the worst-performing stocks in 1998. Due to the
Portfolio's pure value orientation, it generally underperformed portfolios that
were growth oriented in 1998. As a result, the Portfolio underperformed its peer
 
                                       37
<PAGE>   38
 
group which includes growth and income portfolios that pursue growth disciplines
as well as funds that pursue value disciplines.
 
Yet even within the narrower value stock universe, our deep-value approach
seemed to run contrary to the market's preference for large, familiar names,
regardless of cost or underlying value. We continued to seek stocks with low
price-to-earnings ratios and low price to cash flow ratios, even as in some
cases the market seemed to reward stocks with high prices and high
price-to-earnings ratios. Finally, our concentration in traditional value
sectors, such as energy and basic materials, contributed to the Portfolio's
underperformance as financial problems in Asia, Russia, and Latin America
unfolded, bringing lower prices for oil and other major commodities.
 
Fortunately, the declines in traditional deep-value sector stocks helped us add
to many of the Portfolio's positions at what we believe to be very attractive
prices. So while the Portfolio underperformed its peers in 1998, we believe that
the Portfolio is positioned to lead its peers once investors recognize the
attractiveness of value stocks.
 
WHAT WERE SOME OF THE DECISIONS THAT HELPED THE PORTFOLIO IN 1998?
Although the Portfolio is generally underweighted in technology stocks, one of
our most successful decisions was to purchase Adaptec, a major supplier in
technology hardware and software. We purchased the stock for the Portfolio in
the second quarter, and when the Asian crisis caused a correction in the
technology sector, the stock dropped about 50%. At that time, we were even more
convinced that the stock was undervalued, so we doubled the Portfolio's position
when it fell to $10. By the end of 1998, Adaptec stock was trading well above
the Portfolio's average purchase price for the stock, which provided a
significant gain for the Portfolio. The story reflects exactly what we try to do
in the Portfolio -- buy on disappointments and profit as value is realized.
 
Another significant decision for the Portfolio involved our investment in Philip
Morris. We have bought and sold the stock many times over the years, but we made
a significant purchase in the second quarter after the bulk of the negative
publicity about tobacco litigation had already driven down the stock price. At
the time Philip Morris was one of the worst-performing stocks, but we recognized
that even discounting what we believed to be the risk to investors as a result
of existing and potential lawsuits, the company's assets were worth more than
the stock's value. Apparently the market finally realized what we saw in the
stock, which recovered substantially and was one of the Portfolio's
best-performing stocks in 1998.
 
A third positive decision was to add to electric utilities in the first half of
the year, with stocks like Texas Utilities, FPL Group, OGE Energy, Niagara
Mohawk Power, and Energy East. The Portfolio's utility stocks performed very
well during the market correction in the third quarter, actually increasing in
value as the stock market declined nearly 20%. Later in the year, we sold some
of the Portfolio's utility holdings to take profits. One significant sale was
FPL Group, a Florida utility, which the Portfolio sold at a market high, with a
positive impact on the Portfolio's performance.
 
We reinvested the proceeds of the Portfolio's utility stock sales in financial
services stocks, including SLM Holding, Washington Mutual, MGIC Investment, and
Conseco, all of which appeared to be very undervalued on a relative basis. All
of these stocks were trading in the range of 10 to 11 times earnings, when the
price of stocks in general was nearing 25 times earnings. Each of these
financial services stocks had a positive impact on the Portfolio through
year-end.
 
WERE THERE MAJOR DECISIONS THAT HAD A NEGATIVE IMPACT?
Yes there were. As the price of oil declined, the Portfolio purchased stocks of
several midsized energy companies, including Unocal, Union Pacific Resources
Group, Noble Affiliates, and Oryx Energy, believing that they were attractively
priced. The Asian financial crisis reduced manufacturing output which had a
negative impact on demand for oil causing oil prices to decline, so we continued
to purchase more of these stocks for the Portfolio at successively lower prices
throughout the year. In retrospect, we believe our purchasing decisions were
premature, and the overall effect was severely negative in 1998. As industry
fundamentals shift and Asian economies begin to stabilize, we believe the
Portfolio's strong commitment to energy stocks should be rewarded.
 
WHAT OTHER SIGNIFICANT PURCHASES DID YOU MAKE FOR THE PORTFOLIO IN 1998?
In the third quarter of 1998, we increased the Portfolio's HMO stock exposure
with the initial purchase of United Healthcare stock at what we believed to be
bargain basement prices, considering excellent management, strong financial
characteristics, and stock repurchases by the company. We bought the stock in
the mid-$30 range and it has been up ever since, so we believe both the
selection and timing were positive for the Portfolio.
 
                                       38
<PAGE>   39
 
A stock we bought that didn't work out as well was Toys "R" Us. Although the
company met all of our deep-value disciplines, management of the company failed
to deliver on their promises. Earnings have been disappointing and a promised
restructuring has not been successful to date. Although the Portfolio still
holds the stock, we're watching the situation closely.
 
WHAT OTHER SECURITIES DID YOU SELL DURING THE YEAR?
One of the Portfolio's successful sales was its position in Ford Motor. We
purchased the stock for the Portfolio at an attractive price and sold it in July
at a substantial profit. At the time, we believed the auto sector was fully
valued, and the stock did decline after we sold it. So we believe the sale was
positive for the Portfolio.
 
A less successful sale was the stock of Coltec Industries, a leading aerospace
and industrial manufacturing company. When we purchased the stock for the
Portfolio, we thought the company was an excellent value and might be a takeover
target. Although we were right on both counts, offers from two potential
acquirers failed to come close to our original cost. In December, we decided to
cut our losses by selling the shares which had a negative impact on the
Portfolio's performance, since we no longer believed that the management of the
company was acting in the best interests of its shareholders.
 
On a more positive note, the Portfolio sold two deep value stocks, Lexmark
International Group (a laser printer company) and Allegiance (a health care
provider), when they reached the Portfolio's target values. The Portfolio sold
Lexmark International Group in the third quarter for a 69% gain and Allegiance
in July for a gain of 50%. These were two of the best performers in the
Portfolio, and although both stocks rose after we sold them, they performed more
like growth stocks than value candidates and were no longer appropriate holdings
for the Portfolio.
 
WERE THERE OTHER SIGNIFICANT SALES DURING THE YEAR?
Yes. We sold Tenneco, an automotive parts and packaging company, as part of our
decision to cut back on economically sensitive sectors, which was a positive
move for the Portfolio as these sectors generally performed poorly, even though
the Portfolio took a small loss on the stock. In September, we sold Crown Cork &
Seal, a paper, glass, and plastic container company that was suffering from its
exposure to Asia and South America. The company had lowered its earnings
forecasts earlier in the year, and the Portfolio sold based on fears that they
would do so again. Although we sold at a loss, the stock has continued to
underperform, so our decision to sell was good in that it allowed the Portfolio
to reinvest the assets more productively.
 
BESIDES LEXMARK INTERNATIONAL GROUP AND ALLEGIANCE, WHAT WERE THE PORTFOLIO'S
BEST-PERFORMING STOCKS?
We already mentioned selling Ford Motor shares at a substantial profit, which
made it the Portfolio's third-best performer. The Portfolio also profited from
the sale of Echlin, an auto parts company, whose stock advanced dramatically
when the company was acquired by Dana Corp., one of the world's largest supplier
of automotive parts.
 
The Portfolio also earned a 49% return on US West, as it benefited from the
reappraisal of the telecommunications group. Finally, the Portfolio's investment
in the insurance giant CIGNA provided a 37% return, which contributed positively
to the Portfolio's overall return.
 
WHAT ABOUT NEGATIVE PERFORMERS?
In a difficult market for value stocks, the Portfolio had more losers than
winners. Perhaps the worst cases were two stocks that the Portfolio purchased on
their restructuring potential. One was Venator Group, formerly known as
Woolworth. We believe the name change confused the market, and the company
shifted into athletic footwear as the Asian market had difficulties. The ensuing
earnings disappointment was poorly received by investors, and Venator Group
stock lost over half of its value in 1998.
 
Another failed restructuring candidate was Callaway Golf, a manufacturer of golf
equipment, that simply failed to perform up to our expectations. The stock was
purchased at a very cheap relative price, but continued to decline throughout
the year, as Asian conditions worsened.
 
Union Pacific Resources Group was a leveraged company whose oil stock the
Portfolio bought too early. The price declined 50% over the course of the year,
and we have added to the Portfolio's position, believing the market will see the
company's value when oil prices begin to stabilize.
 
Finally, Northwest Airlines, which is the principal air link between the United
States and the Far East, had a dismal year when the Asian crisis hurt its sales
and a labor strike reduced its profits. The Portfolio continues to
 
                                       39
<PAGE>   40
 
hold the stock, believing its long-term potential will be realized as Asia
stabilizes and the strike fades from recent memory.
 
AT YEAR-END, WHERE WAS THE PORTFOLIO OVERWEIGHTED AND UNDERWEIGHTED?
As of 12/31/98, the Portfolio was overweighted in financial services, energy,
electric utilities, basic materials, and HMOs. We believe that the disparity
between the prices of these stocks and their earnings potential gives them
better prospects than the market as a whole. Since stocks in technology,
pharmaceuticals, and consumer staples tend to have high prices and high
price-to-earnings ratios, they don't fit our value disciplines and were
underweighted in the Portfolio at the end of 1998. The Portfolio has not
participated in the rise of Internet stocks, since they represent the exact
opposite of what we look for in long-range investments.
 
WHAT IS YOUR OUTLOOK FOR VALUE STOCKS?
In 1998, the Federal Reserve Board Chairman described the stock market's
performance as "irrational exuberance." When investors ignore basic fundamentals
such as the relationships between price, company worth, cash flow, and earnings,
we tend to agree with his assessment. Ultimately, however, we believe many
investors will have to ask themselves if what they're buying is worth the cost.
At that point, we believe value stocks will once again become desirable
investments and that the Portfolio's deep-value approach will tend to provide
attractive returns.
 
We believe we have already seen the beginnings of a global recession, with
problems throughout Asia, Russia, and Latin America. We have already seen some
stabilization in Asia and may see improvements in Latin America over time. We
believe that as signs of economic strength return, more investors will begin to
focus on stocks which represent value over time. Since value stocks have
traditionally outperformed growth stocks over full market cycles, we see no
reason to vary our approach or change our disciplines. Whatever changes the
markets may bring, the Portfolio will continue to seek to realize maximum
long-term total return from a combination of capital growth and income.

MAINSTAY VP BOND PORTFOLIO
 
1998 MARKET RECAP
- - Global events dominated the fixed income markets in 1998. Fixed income
  securities with the slightest hint of credit risk experienced spread pressure,
  and liquidity became the principal concern of investors.
- - The Federal Reserve Bank eased monetary policy three times during the course
  of the year. The Fed took these actions in an effort to provide liquidity to
  the market and allay fears regarding a global financial crisis.
- - The market experienced a significant rally for the year. The five-year U.S.
  Treasury note declined 116 basis points.
 
1998 PORTFOLIO RECAP
- - For the year-ended 12/31/98, the Portfolio had a return of 9.12%,
  outperforming the average portfolio in its Lipper(1) peer group (Corporate
  Debt A Rated), which returned 8.07%.
- - The Portfolio ranked seventh out of 30 funds (top 23.3%) in its Lipper
  variable product universe.
- - Market risk was limited by maintaining a relatively neutral duration posture
  throughout the year.
- - An average investment portfolio quality of at least AA- was maintained
  throughout the year, limiting credit risk.
 
MANAGEMENT DISCUSSION AND ANALYSIS
Early in 1998, the bond market exhibited surprising stability. This stability
was the result of two opposing forces, severely weakened foreign economies
countered by a domestic economy which continued to exhibit strength. As the year
progressed, a series of global events led to a significant flight to quality
trade. This created a tremendous demand for liquid, high quality securities.
Concerns about defaults in Russia, its contagion effect on other emerging
markets, the continued banking crisis in Japan along with hedge fund
liquidations put enormous downward pressure on risk assets. In late September,
the Federal Reserve Bank initiated a series of interest rate cuts in an effort
to provide calm to the markets. The Federal Reserve actions proved effective, as
risk asset classes regained stability in the fourth quarter.
 
TO WHAT DO YOU ATTRIBUTE THE PORTFOLIO'S POSITIVE PERFORMANCE?
The conservative nature of the Portfolio aided it greatly in 1998. The
Portfolio's high overall credit quality insulated it from the extreme spread
pressure experienced by portfolios with a higher concentration of risk assets.
The Portfolio had minimal exposure to sectors most adversely affected by the
global financial crisis such as high yield and emerging markets.
 
WHAT WAS YOUR PRIMARY STRATEGY DURING 1998?
The Portfolio shifted assets from the corporate and mortgage sectors to the U.S.
Treasury sector. We took these actions to take advantage of the flight to
quality trade and to reduce the Portfolio's credit and call risk. The
Portfolio's investments credit quality improved from AA- to AA+ during the
course of the year.
 
WHERE DO YOU PERCEIVE RISK IN THE PORTFOLIO?
If risk asset classes such as emerging market debt and high yield rebound in
1999, our underweighting in these sectors could hamper our performance relative
to our peer group. The Portfolio's investments overall credit quality and
structure continues to be consistent with our long-term conservative approach to
managing the Portfolio. However, if we see value in riskier asset classes during
the course of the year, we will make Portfolio adjustments to take advantage of
these opportunities.
 
WHAT IS YOUR OUTLOOK FOR THE FIXED INCOME MARKET IN 1999?
The Federal Reserve's interest rate cuts in 1998 have lowered, but not
eliminated, the risk of a pending recession. The robust stock market along with
recent economic strength should keep the Federal Reserve on hold in the early
part of the year. With spreads at historically wide levels, we see an
opportunity in the corporate bond market.
 
Trepidation about global economies such as Brazil, along with the Y2K issue and
a potential stock market correction, could put the Federal Reserve back in the
easing mode later this year.

MAINSTAY VP GROWTH EQUITY PORTFOLIO
 
1998 MARKET RECAP
- - International economic weakness caused U.S. corporate profit growth to
  decelerate.
- - Global recession fears prompted three interest rate cuts by the Federal
  Reserve.
- - The market saw strong inflows into mutual funds and increased demand for U.S.
  equities by foreigners.
- - Record levels of merger and acquisition activity helped boost equity
  valuations.
 
1998 PORTFOLIO RECAP
- - For the year ended 12/31/98, the MainStay VP Growth Equity Portfolio returned
  26.59%.
- - The Portfolio outperformed the Lipper(1) Variable Products growth fund average
  of 24.94%.
- - The Portfolio benefited from its holdings of technology stocks, which
  generated extremely strong returns throughout the year.
- - The Portfolio's health care and consumer holdings also provided substantial
  gains in 1998.
 
MANAGEMENT DISCUSSION AND ANALYSIS
The main issue facing investors in 1998 was the debate over the impact of
economic problems of emerging markets on the U.S. economy and financial markets.
The market's perception of emerging market problems grew from being a non-event
early in the year to a full-scale crisis by the end of the third quarter.
Fortunately, the Federal Reserve and foreign central banks were able to enact a
coordinated round of global interest rate cuts. The easing of money supply
provided liquidity for the financial markets and enabled investor confidence to
return.
 
The market was also impacted by several favorable liquidity factors in 1998.
Mainly, foreign investment into the U.S. equity market was at record levels as
international investors sought out the world's strongest economy in a time of
global economic uncertainty. In addition, over a billion dollars of merger and
acquisition activity helped enhance equity valuations while shrinking supply.
Finally, individual investor demand remained robust as the public continued to
invest through mutual funds.
 
Market performance was narrow once again in 1998 as larger capitalization issues
outperformed smaller capitalization issues by a wide margin. While the S&P 500
Index(2) was up 28.6% in 1998, the median stock in the index returned
approximately 7.0%. These figures point to the fact that investors wanted to
place their money in larger issues with consistent earnings growth.
 
CAN YOU DISCUSS THE MAINSTAY VP GROWTH EQUITY PORTFOLIO'S PERFORMANCE?
For the year-ended 12/31/98, the MainStay VP Growth Equity Portfolio had a total
return of 26.59%. Once again this placed us ahead of the Lipper Variable
Products growth fund average return of 24.94%. This marked the sixth time in the
last seven years that we have outperformed the Lipper Variable Products growth
fund average.
 
WERE THERE ANY MAJOR EVENTS IN 1998, WHICH CAUGHT YOU BY SURPRISE? HOW DID YOU
REACT?
A major surprise of 1998 was not that the Federal Reserve began lowering
interest rates in October but the aggressiveness they displayed in doing so.
Earlier in the year, there were many conflicting signals on the direction of the
economy. The Federal Reserve chose to retain a neutral posture. However, as it
became clear that emerging market problems were starting to affect the U.S.
economy and financial markets, the Federal Reserve had no other option than to
lower interest rates. Another surprise was the speed in which the equity market
responded to the Federal Reserve's easings. The old saying "Never fight the Fed"
really held in the fourth quarter of 1998.
 
We responded to the Federal Reserve's action by quickly moving more cash into
the market, although the Portfolio kept a higher position in cash than normal
given our concerns about the tenacity of the market rally. We decided to
increase the Portfolio's technology holdings as they appeared to have the best
relative growth prospects in the market while also focusing on certain companies
such as United States Filter which saw its stock price inordinately hurt by the
third quarter's correction.
 
WHAT WERE THE PORTFOLIO'S BEST OVERALL PERFORMERS IN 1998?
The Portfolio's best overall performers were mainly technology issues. This
comes as no surprise as this sector was the equity market's performance leader
by a wide margin. In particular, Internet related stocks were the best
performers. America Online was by far the Portfolio's best performing stock of
the year with an astonishing return of 586%. The stock appreciated as many
investors began to believe in the viability of the Internet. Despite the fact
that America Online is one of the few Internet companies with operating profits,
we are
 
                                       43
<PAGE>   44
 
somewhat concerned with the valuation of the stock and the Portfolio has taken
some gains as its stock price has moved up. The stock of EMC was another strong
performer with a return of 209% for the year.
 
Cisco Systems stock continued to display strong gains in 1998 with a return of
149%. The company continues to be a preeminent provider of networking and
communications equipment.
 
WHAT WERE THE PORTFOLIO'S WORST OVERALL PERFORMERS IN 1998?
The Portfolio's worst performing stocks were its holdings of Halliburton and
Schlumberger which were both down approximately 41% for the year. Both companies
are involved in the oil drilling and equipment industry, which has fallen on
tough times of late with the severe downturn seen in energy prices.
Unfortunately, we underestimated the effect that falling energy prices would
have on these stocks. Currently, we view each of these stocks as value holdings
while we await a turnaround in the energy sector. Another stock that negatively
impacted the Portfolio was Equifax, which decreased 11%. The company, a provider
of credit information, pre-announced an earnings disappointment in late
December, which caused a steep decline in the price of the stock. The adverse
reaction was a result of operating problems in the company's European operations
which interrupted the company's record of consistent earnings growth.
 
CAN YOU GO OVER SOME OF THE BEST DECISIONS YOU MADE?
The best decision we made was to keep the Portfolio with a growth stock
orientation, which proved most beneficial as growth stocks continued to
outperform value stocks by a wide margin. We also let the Portfolio's cash
position build up during the summer correction, which helped offset some
potential losses. In particular, we were timely in lowering the Portfolio's
exposure to the financial sector at that time. Another decision which proved
beneficial was increasing the Portfolio's technology exposure in late November.
This was a timely call as this sector surged in the month of December. The
Portfolio's three new holdings that month, Sun Microsytems, Texas Instruments
and Hewlett-Packard were positive contributors to year-end results.
 
WHAT WERE SOME OF THE WORST DECISIONS YOU MADE?
Probably one of the worst decisions was not having a higher weighting in
technology holdings. While the Portfolio was moderately overweighted in
technology throughout the year, it would have benefited to a greater extent with
a higher weighting. In addition, the Portfolio's investment position in the
energy sector, while underweighted, was too high. In particular, the Portfolio's
oil service positions were especially weak performers. While the Portfolio's
holdings in this sector did not perform up to our expectations, the relative
performance was exacerbated by the extremely strong performance of the equity
market in the fourth quarter.
 
WERE YOU SIGNIFICANTLY OVERWEIGHTED OR UNDERWEIGHTED IN ANY SECTORS?
The Portfolio does not significantly overweight or underweight any major market
sectors as we manage the Portfolio as a relatively sector balanced portfolio. We
keep the Portfolio's sector weightings between 0.5 times and 1.5 times the
appropriate S&P 500 sector weighting. The Portfolio's sector weightings have
been an important component in its excellent performance. These weightings are
determined from our global outlook on the macroeconomic environment.
 
WHAT IS YOUR STRATEGIC OUTLOOK GOING FORWARD?
We remain somewhat optimistic on the equity market, but with some reservations.
Our optimism is based primarily on our positive outlook for low inflation and
interest rates. However, corporate earnings growth should be restrained in the
5-7% range. In such an environment, we expect traditional growth stocks to
continue to lead the market.
 
Our positive stance on the market could be seriously tested by the potential
problems resulting from the Y2K or millenium bug, which could seriously impact
our economy if remediations are not completed by year-end. We will closely
monitor the progress of the government and business community in regard to their
Y2K compliance.

MAINSTAY VP INDEXED EQUITY PORTFOLIO
 
1998 MARKET RECAP
- - The U.S. economy continued to expand in a favorable environment of generally
  solid corporate earnings growth, low interest rates, and extraordinarily tame
  inflation.
- - In the third quarter, however, the Russian economic collapse, a weakening
  economic outlook in Latin America and ongoing economic woes in Asia combined
  with lower corporate profits and expectations of slower growth in the U.S.,
  caused equity markets to tumble.
- - Fears of global recession and financial market instability prompted the
  Federal Reserve Board to move to lower interest rates 0.25% three separate
  times beginning in late September, providing an enormous psychological boost
  that set the stage for the equity markets' unexpectedly speedy rebound in the
  fourth quarter.
 
1998 PORTFOLIO RECAP
- - For the one-year period ended 12/31/98, the MainStay VP Indexed Equity
  Portfolio returned 28.49%.
- - The Portfolio closely tracked the S&P 500 Index's(1) return of 28.58% and
  exceeded the 14.52% return of the Lipper(2) general equity average for the
  one-year period ended 12/31/98.
- - Buoyed by positive investor sentiment toward their higher liquidity and
  relative safe haven status, the large-capitalization stocks of which the
  Portfolio is composed outperformed their mid- and small-capitalization
  counterparts, the S&P 400 Mid Cap(3) and S&P 600 Small Cap(4) Indices by a
  wide margin.
- - The Portfolio outperformed the average Lipper Variable Products S&P 500 Index
  objective portfolio, which returned 28.25% for the one-year period ended
  12/31/98.
 
MANAGEMENT DISCUSSION AND ANALYSIS
Overall in 1998, tame inflation and a corresponding drop in interest rates had
an impact on stock prices, with the S&P 500 Index gaining 28.58% for the
one-year period ended 12/31/98. Against a backdrop of above-average corporate
productivity, falling producer prices (i.e. the cost of raw materials), and
heavy consumer spending, the market for large-capitalization stocks managed to
post its fourth consecutive annual gain in excess of 20%. Giant mergers among
the telecommunications, financial services, and heavy industry sectors made
headlines throughout the year.
 
During the first six months of the year, the S&P 500 climbed even as volatility
increased, crossing the 1,000 mark for the first time in February 1998. As fears
of a tightening by the Federal Reserve Board mounted during the second quarter,
the markets began a roller-coaster ride of volatility that began in April and
continued through June. Lower corporate profits, expectations of slower U.S.
corporate growth, and the General Motors strike helped to push stocks to tumble
in a July sell-off. Bad news continued in August, as Russia devalued its
currency and defaulted on its domestic debt; weak commodity prices helped to
dampen the economic outlook for Latin America; and ongoing economic instability
in Asia generally impacted markets worldwide. Declining consumption in these
geographic regions and their ability to export to the U.S. less expensively, put
considerable downward pressure on corporate profitability. An impending credit
crunch, political infighting, and the collapse of a high profile hedge fund only
added to investor concerns. The result of all this -- the S&P 500's return in
August was one of the ten worst since the Index's inception on 12/31/25.
 
The S&P 500 Index scored tremendous gains early in September, which helped it to
quickly recover more than half of its August losses before faltering toward the
end of the month. Frustrated by a smaller-than-expected 0.25% interest rate cut
by the Federal Reserve Board at the end of September, the markets tumbled once
again, only to roar back as the Federal Reserve rapidly cut rates 0.25% twice
more in the fourth quarter. This demonstrated commitment to maintain global
financial stability -- along with a lack of panic amongst small market investors
after the summer plunge -- was all the markets needed to spark a powerful rally
that fueled the strongest fourth quarter returns in some twenty years for most
of the major U.S. large-cap equity indices. The quarter was led by the
technology sector in general and Internet-related stocks in particular.
 
GIVEN THIS CONTEXT, HOW DID THE MAINSTAY VP INDEXED EQUITY PORTFOLIO PERFORM IN
1998?
The MainStay VP Indexed Equity Portfolio returned 28.49% for the year-ended
12/31/98, outperforming the average Lipper Variable Products S&P 500 Index
objective portfolio which returned 28.25% for the same period.

DID THE PORTFOLIO'S COMPOSITION CHANGE OVER THE YEAR?
Yes. The S&P 500 Index is not static. Mergers, acquisitions, spin-offs, and the
success and failure of some companies can impact which companies are included in
the Index -- and their relative weightings. During 1998, there was an abundance
of corporate giant mergers that changed the composition of the S&P 500 Index,
and thus the Portfolio. Specifically, at year-end, there were 48 changes to the
Index, over 75% of which were due to mergers and acquisitions.
 
WHICH WERE THE PORTFOLIO'S MOST SIGNIFICANT PURCHASES AND SALES DURING THE
ANNUAL PERIOD?
All purchases and sales were executed in an attempt to invest in stocks in the
same proportions as they are represented in the Index. Significant purchases
included securities of America Online, General Electric, Microsoft, Coca-Cola,
Exxon, Intel, AT&T, Merck, Pfizer and Safeway. Significant sales included
securities of Amoco, Chrysler, General Re, General Electric, MCI WorldCom,
Exxon, International Business Machines, Microsoft, and Intel.
 
WHICH OF THE PORTFOLIO'S INDIVIDUAL STOCKS SHOWED THE BEST PERFORMANCE DURING
1998?
America Online generated the single highest gain for the year, rising 586%.
Other strong performers included Dell Computer, up 249%; Apple Computer, up
212%; EMC, up 210%; Lucent Technologies, up 175%; Ascend Communications, up
168%; Providian Financial, up 149%; Unisys, up 148%; and Compuware, which rose
144%.
 
WHICH INDIVIDUAL STOCKS RECORDED THE WORST PERFORMANCE DURING 1998?
Harnischfeger Industries was the worst-performing stock in the S&P 500, with a
decline of 71%. IKON Office Solutions fell 70%; Rowan fell 68%; Case was down
64%; and Union Pacific Resources Group declined 63% for the year.
 
WHAT IS YOUR OUTLOOK FOR THE FUTURE?
Stocks are inherently risky investments. While they historically have provided
investors with attractive returns and outperformed all other major asset classes
over the long term, investors must be aware that over shorter periods of time,
their prices may fluctuate in value, often dramatically.
 
The objective of the MainStay VP Indexed Equity Portfolio is to provide
investment results that correspond to the total return performance of its
benchmark index, the S&P 500 (reflecting reinvestment of dividends). As a
result, we do not respond to nor evaluate changing market and economic
conditions. Nor do we manage according to a given outlook for the equity markets
or the economy in general.
 
However, it seems unlikely that stock market returns can continue at the levels
we have seen in recent years. As 1998 has once again proven, equity markets are
unpredictable, particularly in the short term, and no one can know with absolute
certainty whether the markets will rise or fall in 1999. That's why we feel it
is important for investors to keep focused on their long-term goals despite
short-term volatility.

                                    GLOSSARY
 
ASSET-BACKED SECURITIES:  Securities backed by loan paper, receivables, or an
anticipated income stream from the sale of merchandise or services. The
securities are generally originated by banks, credit card companies, or other
providers of credit and often "enhanced" by a bank letter of credit or by
insurance from an institution other than the issuer.
 
BASIS POINT:  One hundredth of one percent in the yield of an investment, i.e.,
100 basis points equals 1%.
 
BOTTOM-UP INVESTING:  Security selection based on the specific portfolio
fundamental merits of individual issues. The opposite of "top-down" investing,
which starts with general economic trends, compares market sectors, and uses
relative security values to narrow the range of issues to examine.
 
BULL MARKET/BEAR MARKET:  A bull market occurs when security prices are rising;
a bear market occurs when security prices decline. A bullish attitude therefore
suggests a positive outlook, while a bearish attitude represents a negative view
of the market or the opportunities it may present.
 
CALL RISK:  A bondholder's risk that the bond may be redeemed by the issuer
prior to maturity.
 
CAPITALIZATION:  The amount of outstanding equity and debt a company has issued.
Companies may vary greatly in the amount of equity capital they have raised, and
their capitalization may change with new issues or stock repurchases.
 
CASH FLOW:  The amount of income or earnings available to cover outstanding
liabilities and other obligations, including debt service.
 
COLLATERALIZED MORTGAGE OBLIGATION (CMO):  Mortgage-backed bond that separates
mortgage pools into different maturity classes, called tranches. This is
accomplished by applying income from mortgages in the pool in the order that the
CMOs pay out. Tranches pay different rates of interest and typically mature in
2, 5, 10 or 20 years. CMOs are issued by the Federal Home Loan Mortgage
Corporation (Freddie Mac) and by private issuers. They are usually backed by
government-guaranteed or other top-grade mortgages and have AAA bond ratings.
 
COMMODITIES:  Bulk goods, such as grains, precious metals, industrial metals,
and foods traded on a commodities exchange.
 
CONVERSION PREMIUM:  The amount by which the price of a convertible security
exceeds the market price of the underlying stock. If a stock is trading at $50
and the convertible bond at $45 is trading at $50, the premium is $5. When the
premium is high, the bond trades like an income security; when it is low, it
trades like a stock.
 
CORRECTION:  A market shift in security prices that brings them more in line
with historically appropriate levels.
 
CREDIT RISK:  The risk that the issuer of a security may go into bankruptcy or
default on payments, causing the investor to lose all or part of the investment.
 
CYCLICALS (CYCLICAL STOCK):  A security or stock that tends to rise quickly with
economic upturns and fall quickly when the economy slows. Noncyclical
industries, such as food, insurance, and pharmaceuticals, are likely to have
more consistent performance regardless of economic changes.
 
DEVALUATION:  A lowering of the value of a country's currency relative to gold
and/or the currencies of other nations. Devaluation can also result from a rise
in the value of other currencies relative to the currency of a particular
country.
 
DURATION:  A measure of price sensitivity, which adjusts for the time value of
the payments investors will receive and which takes into account interest
payments as well as principal payments. Duration is a better gauge of
interest-rate sensitivity than average maturity alone.
 
EARNINGS PER SHARE:  The portion of a company's profit allocated to each share
of outstanding common stock.
 
ECONOMIES OF SCALE:  Production and purchasing efficiencies enjoyed by larger
organizations, by spreading costs over a larger base or purchasing items at
volume discounts.
 
EMERGING MARKETS:  Countries with smaller or more recently established capital
markets.
 
EUROPEAN MONETARY UNION:  A system that allows participating European countries
to operate with a common currency or monetary unit.
 
FEDERAL RESERVE BOARD:  The seven member governing board of the Federal Reserve
System, which is the central bank of the United States. The Board sets policies
on reserve requirements, bank regulations, sets the
 
                                       49
<PAGE>   50
 
discount rate, tightens or loosens the availability of credit in the economy and
regulates the purchase of securities on margin.
 
FIRST-TIER/SECOND-TIER:  Money market instruments in the highest rating category
by two or more major rating agencies are called first-tier or top-tier
securities, while securities in the second-highest rating category by two or
more major rating agencies are referred to as second-tier securities.
 
FLIGHT TO QUALITY:  When investors in general move to improve the quality or
liquidity of the securities they own, because of economic, industry, market or
credit concerns that suggest lower quality securities or those that are less
liquid are likely to be more vulnerable to negative market events.
 
GROSS DOMESTIC PRODUCT (GDP):  The total value of goods and services produced in
the U.S. economy over a particular period of time, usually one year. The GDP
growth rate measures strictly domestic output and is a primary indicator of the
status of the economy.
 
GROWTH VERSUS VALUE:  Growth investments typically include stocks with rising
prices and positive earnings trends. Value investments typically include
equities that are currently trading below their fair market value, even if they
have the potential to increase in value over time.
 
HEDGE FUND:  A private investment partnership or off-shore investment
corporation that may take both long and short positions, use leverage and
derivative securities, and invest across many markets. Hedge funds may use
high-risk or speculative investment strategies and move billions of dollars in
and out of the markets quickly.
 
INFLATION/DEFLATION:  Inflation is an increase in the cost of goods and services
over time. As prices rise, the purchasing power of the dollar declines.
Deflation is a reduction in the cost of goods over time. When deflation occurs,
the purchasing power of the dollar increases.
 
LIQUIDITY:  Securities are said to be liquid when they can be easily bought or
sold in large volume without substantially affecting their price. Some
securities, such as private placements or stocks that have few shares
outstanding are considered illiquid either because there are few market
participants interested in buying or selling the securities or because purchases
and sales may cause wide price swings.
 
LOCAL CURRENCY TERMS:  Returns expressed in local currency terms show what
investors using that currency would have earned, without any adjustment for
differences in currency values. Returns expressed in U.S. dollar terms reflect
any differences in the relative value of the local currency and the U.S. dollar.
 
MERGERS AND ACQUISITIONS:  A merger is a combination of two companies. An
acquisition is the purchase of a company, division, or business unit. Companies
that engage in mergers and acquisitions often pay shareholders a premium, or an
amount over the current share price, to complete the transaction quickly and
under favorable terms.
 
MORTGAGE-BACKED SECURITIES:  Securities representing interests in "pools" of
mortgages in which principal and interest payments by the holders of underlying
fixed- or adjustable-rate mortgages are, in effect, "passed through" to
investors (net of fees paid to the issuer or guarantor of the securities).
 
PREMIUM:  The amount by which a bond sells above its face or par value. For
example, a bond with a face value of $1,000 would sell for a $100 premium when
it cost $1,100. Different from the conversion premium, which is the amount by
which the price of a convertible exceeds the market price of the underlying
stock.
 
PREPAYMENT:  When mortgage or loan holders repay their obligations before they
mature, shortening the stream of interest payments investors receive.
 
PRICE-TO-CASH FLOW RATIO:  The relationship between the price of a stock and the
amount of free cash flow the company is able to generate.
 
PRICE-TO-EARNINGS RATIO:  The price of a stock divided by its earnings per
share.
 
PROXY HEDGE:  A transaction in the forwards market that seeks to offset
investment risk by substituting exposure to one foreign currency with exposure
to another.
 
REAL ESTATE INVESTMENT TRUST (REIT):  A publicly traded company that purchases
and manages a portfolio of real estate properties for the benefit of
shareholders.
 
RECESSION:  A downturn in economic activity, typically defined by at least two
consecutive quarters of decline in a country's gross domestic product.
 
                                       50
<PAGE>   51
 
RESTRUCTURING:  Any action designed to improve the overall financial structure,
labor relations, or productivity of a company. Restructuring may include such
steps as changing management, investing in new plant and equipment, engaging in
mergers and acquisitions, or taking other action to increase output or lower
costs.
 
SPIN-OFF:  A form of corporate divestiture that results in a subsidiary or
division becoming an independent company.
 
SPLIT ISSUES (SPLIT-RATED ISSUES):  Securities rated top tier by one credit
rating agency and second tier by another.
 
SUPPLY AND DEMAND:  In the bond market, supply is influenced by the amount of
new securities issued and the amount of bonds investors wish to sell. Demand
reflects the amount of bonds investors wish to buy, which may decrease when
other markets offer greater opportunities.
 
In the stock market, an oversupply of a product or service can reduce demand and
lower stock prices. When demand increases relative to supply, stock prices may
recover.
 
SWAP:  Exchange of one security for another. A swap may be executed to change
the maturities of a bond portfolio or the quality of the issues in a stock or
bond portfolio, or because investment objectives have changed.
 
TENDER:  To offer money or goods in settlement for a prior debt or claim.
 
TIGHTEN/EASE:  When the Federal Reserve Board moves to raise interest rates, it
is said to be "tightening" or making borrowing more expensive. When it moves to
lower rates, it is said to be "easing" or making borrowing more affordable.
 
TOTAL RETURN:  The performance of an investment with all income and capital
gains reinvested.
 
VOLATILITY:  Fluctuations in the price of securities or markets, up or down,
over a short period of time.
 
WEIGHTING:  The proportion of a portfolio allocated to a specific security,
market sector or country, i.e., a portfolio is said to be overweighed in a
sector or country when that portion of the portfolio is greater than the
sector's general relationship to the market as a whole or the country's total
equities relative to the international equity markets as a whole.
 
YANKEE ISSUES:  Dollar-denominated income securities issued in the United States
by foreign banks and corporations, usually when conditions in the U.S. are more
favorable than in other markets, including the issuer's domestic market
overseas.
 
YIELD:  The income per share (or current value of a security) paid to investors
over a specified period of time as a percentage of the cost of the security.
Mutual fund yields are expressed as a percentage of the fund's current price per
share.
 
YIELD CURVE:  When interest rates available from various short-, intermediate-,
and long-term securities are plotted on a graph, the resulting line is known as
a yield curve.
 
YIELD SPREAD:  The difference in yield between securities in different market
sectors, such as government and mortgage-backed securities -- or between
different securities in a single sector, such as 2- and 30-year Treasuries or
PRIME-1 and PRIME-2 rated commercial paper.
 
Y2K:  A reference to the Year 2000.

NOTES TO FINANCIAL STATEMENTS
 
NOTE 1-- Organization and Accounting Policies:
- --------------------------------------------------------------------------------
 
NYLIAC Corporate Sponsored Variable Universal Life Separate Account-I ("CSVUL
Separate Account-I") was established on May 24, 1996, under Delaware law by New
York Life Insurance and Annuity Corporation ("NYLIAC"), a wholly-owned
subsidiary of New York Life Insurance Company. Investments into CSVUL Separate
Account-I commenced on March 27, 1998. The CSVUL Separate Account-I policies are
designed for Group or Sponsored arrangements who seek lifetime insurance
protection and flexibility with respect to premium payments and death benefits.
The policies are distributed by NYLIFE Distributors Inc. and sold by registered
representatives of broker-dealers who have entered into dealer agreements with
NYLIFE Distributors Inc. NYLIFE Distributors Inc. is a wholly-owned subsidiary
of NYLIFE Inc., which is a wholly-owned subsidiary of New York Life Insurance
Company. CSVUL Separate Account-I is registered under the Investment Company Act
of 1940, as amended, as a unit investment trust.
 
  The assets of CSVUL Separate Account-I are invested in the shares of the
MainStay VP Series Fund, Inc., the Alger American Fund, the Calvert Variable
Series, Inc. (formerly, "Acacia Capital Corporation"), the Fidelity Variable
Insurance Products Fund II, the Fidelity Variable Insurance Products Fund, the
Janus Aspen Series and the Morgan Stanley Universal Funds, Inc. (collectively,
"Funds"). These assets are clearly identified and distinguished from the other
assets and liabilities of New York Life Insurance and Annuity Corporation.
 
  CSVUL Separate Account-I offers the following eighteen variable Investment
Divisions, with their respective fund portfolios, for Policyowners to invest
premium payments: MainStay VP Capital Appreciation, MainStay VP Cash Management,
MainStay VP Convertible, MainStay VP Government, MainStay VP High Yield
Corporate Bond, MainStay VP International Equity, MainStay VP Total Return,
MainStay VP Value, MainStay VP Bond, MainStay VP Growth Equity, MainStay VP
Indexed Equity, Alger American Small Capitalization, Calvert Social Balanced
(formerly "Calvert Socially Responsible"), Fidelity VIP II Contrafund, Fidelity
VIP Equity-Income, Janus Aspen Series Balanced, Janus Aspen Series Worldwide
Growth and Morgan Stanley Emerging Markets Equity. As of December 31, 1998 no
investments have been made in the following Investment Divisions: MainStay VP
Convertible, MainStay VP Total Return, and Morgan Stanley Emerging Markets
Equity. Each Investment Division of CSVUL Separate Account-I will invest
exclusively in the corresponding Eligible Portfolio.
 
  Initial premium payments received are allocated to NYLIAC's General Account
until 20 days after the policy delivery date. Thereafter, premium payments will
be allocated to the Investment Divisions of CSVUL Separate Account-I in
accordance with the Policyowner's instructions. In addition, the Policyowner has
the option to transfer amounts between the Investment Divisions of CSVUL
Separate Account-I and the Fixed Account of New York Life Insurance and Annuity
Corporation.
 
  No Federal income tax is payable on investment income or capital gains of
CSVUL Separate Account-I under current Federal income tax law.
 
  Security Valuation--The investments are valued at the net asset value of
shares of the respective Fund portfolios.
 
  Security Transactions--Realized gains and losses from security transactions
are reported on the identified cost basis. Security transactions are accounted
for as of the date the securities are purchased or sold (trade date).
 
  Distributions Received--Dividend income and capital gain distributions are
recorded on the ex-dividend date and reinvested in the corresponding portfolio.
 
  The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates.

NOTE 3--Mortality and Expense Risk Charges:
- --------------------------------------------------------------------------------
 
CSVUL Separate Account-I is charged for the mortality and expense risks assumed
by New York Life Insurance and Annuity Corporation. These charges are made daily
at an annual rate of .70% of the daily net asset value of each Investment
Division for policy years one through ten. For policy years eleven and later, an
annual rate of .30% is deducted. New York Life Insurance and Annuity Corporation
may increase these charges in the future up to a maximum annual rate of .90%.
The amounts of these charges retained in the Investment Divisions represent
funds of New York Life Insurance and Annuity Corporation. Accordingly, New York
Life Insurance and Annuity Corporation participates in the results of each
Investment Division ratably with the Policyowners.
 
- --------------------------------------------------------------------------------
NOTE 4--Distribution of Net Income:
- --------------------------------------------------------------------------------
 
CSVUL Separate Account-I does not expect to declare dividends to Policyowners
from accumulated net investment income and realized gains. The income and gains
are distributed to Policyowners as part of withdrawals of amounts (in the form
of surrenders, death benefits or transfers) in excess of the net premium
payments.

REPORT OF INDEPENDENT ACCOUNTANTS
- --------------------------------------------------------------------------------
To the Board of Directors of New York Life Insurance and
Annuity Corporation and the Corporate Sponsored Variable Universal Life
Policyowners:
 
In our opinion, the accompanying statement of assets and liabilities and the
related statements of operations, of changes in total equity and the selected
per unit data present fairly, in all material respects, the financial position
of the MainStay VP Capital Appreciation, MainStay VP Cash Management, MainStay
VP Convertible, MainStay VP Government, MainStay VP High Yield Corporate Bond,
MainStay VP International Equity, MainStay VP Total Return, MainStay VP Value,
MainStay VP Bond, MainStay VP Growth Equity, MainStay VP Indexed Equity, Alger
American Small Capitalization, Calvert Social Balanced, formerly known as
Calvert Socially Responsible, Fidelity VIP II Contrafund, Fidelity VIP
Equity-Income, Janus Aspen Series Balanced, Janus Aspen Series Worldwide Growth,
and Morgan Stanley Emerging Markets Equity Investment Divisions (constituting
the NYLIAC Corporate Sponsored Variable Universal Life Separate Account-I) at
December 31, 1998, and the results of each of their operations, the changes in
each of their total equity, and the selected per unit data for the period March
27, 1998 (Commencement of Investment) through December 31, 1998 in conformity
with generally accepted accounting principles. These financial statements and
the selected per unit data (herein referred to as the "financial statements")
are the responsibility of management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audit 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
audit, which included confirmation of investments at December 31, 1998 with the
MainStay VP Series Fund, Inc., the Alger American Fund, the Calvert Variable
Series Inc., the Fidelity Variable Insurance Products Fund II, the Fidelity
Variable Insurance Products Fund, the Janus Aspen Series, and the Morgan Stanley
Universal Funds, Inc., provide a reasonable basis for the opinion expressed
above.

NOTES TO FINANCIAL STATEMENTS
 
NOTE 1-- Organization and Business:
- --------------------------------------------------------------------------------
 
MainStay VP Series Fund, Inc. (the "Fund") was incorporated under Maryland law
on June 3, 1983. The Fund is registered under the Investment Company Act of
1940, as amended, ("Investment Company Act") as an open-end diversified
management investment company. Convertible Portfolio, which commenced operations
on October 1, 1996, High Yield Corporate Bond, International Equity and Value
Portfolios, which commenced operations on May 1, 1995, Capital Appreciation,
Cash Management, Government, Total Return and Indexed Equity Portfolios, which
commenced operations on January 29, 1993 and Bond and Growth Equity Portfolios,
which commenced operations on January 23, 1984, (the "Portfolios"; each
separately a "Portfolio") are separate Portfolios of the Fund. Shares of the
Portfolios are currently offered only to New York Life Insurance and Annuity
Corporation ("NYLIAC"), a wholly owned subsidiary of New York Life Insurance
Company ("New York Life"). NYLIAC allocates shares of the Portfolios to, among
others, New York Life Insurance and Annuity Corporation's Corporate Sponsored
Variable Universal Life Separate Account-I. The Separate Account is used to fund
flexible premium corporate sponsored variable life insurance policies.
 
The investment objectives for each of the Portfolios of the Fund are as follows:
 
Capital Appreciation:  to seek long-term growth of capital.
 
Cash Management:  to seek as high a level of current income as is considered
consistent with the preservation of capital and liquidity.
 
Convertible:  to seek capital appreciation together with current income.
 
Government:  to seek a high level of current income, consistent with safety of
principal.
 
High Yield Corporate Bond:  to maximize current income through investment in a
diversified portfolio of high yield, high risk debt securities which are
ordinarily in the lower rating categories of recognized rating agencies.
 
International Equity:  to seek long-term growth of capital by investing in a
portfolio consisting primarily of non-U.S. equity securities.
 
Total Return:  to realize current income consistent with reasonable opportunity
for future growth of capital and income.
 
Value:  to realize maximum long-term total return from a combination of capital
growth and income.
 
Bond:  to seek the highest income over the long term consistent with
preservation of principal.
 
Growth Equity:  to seek long-term growth of capital with income as a secondary
consideration.
 
Indexed Equity:  to provide investment results that correspond to the total
return performance (reflecting reinvestment of dividends) of common stocks in
the aggregate, as represented by the S&P 500.
 
There are certain risks involved in investing in foreign securities that are in
addition to the usual risks inherent in domestic instruments. These risks
include those resulting from future adverse political and economic developments
and possible imposition of currency exchange blockages or other foreign
governmental laws or restrictions.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 2--Significant Accounting Policies:
- --------------------------------------------------------------------------------
 
The following is a summary of significant accounting policies followed by the
Fund:
 
                                      (A)
 
VALUATION OF FUND SHARES. The net asset value per share of each Portfolio is
calculated on each day the New York Stock Exchange (the "Exchange") is open for
trading as of the close of regular trading on the Exchange. The net asset value
per share is calculated for each Portfolio by dividing the current market value
(amortized cost, in the case of Cash Management Portfolio) of the Portfolio's
total assets, less liabilities, by the total number of outstanding shares of
that Portfolio.
 
                                      (B)
 
SECURITIES VALUATION. Portfolio securities of Cash Management Portfolio are
valued at amortized cost, which approximates market value. The amortized cost
method involves valuing a security at its cost on the date of purchase and
thereafter assuming a constant amortization to maturity of the difference
between such cost and the value on maturity date.
 
Securities of each of the other Portfolios are stated at value determined (a) by
appraising common and preferred stocks which are traded on the Exchange at the
last sale price on that day or, if no sale occurs, at the mean between the
closing bid and asked prices, (b) by appraising common and preferred stocks
traded on other United States national securities exchanges or foreign
securities exchanges as nearly as possible in the manner described in (a) by
reference to their principal exchange, including the National Association of
Securities Dealers National Market System, (c) by appraising over-the-counter
securities quoted on the National Association of Securities Dealers NASDAQ
system (but not listed on the National Market System) at the bid price supplied
through such system, (d) by appraising over-the-counter securities not quoted on
the National Association of Securities Dealers NASDAQ system and securities
listed or traded on certain foreign exchanges whose operations are similar to
the U.S. over-the-counter market, at prices supplied by the pricing agent or
brokers selected by the Adviser (see Note 3) if these prices are deemed to be
representative of market values at the regular close of business of the
Exchange, (e) by appraising debt securities at prices supplied by a pricing
agent selected by the Adviser, whose prices reflect broker/dealer supplied
valuations and electronic data processing techniques if those prices are deemed
by the Adviser to be representative of market values at the regular close of
business of the Exchange, (f) by appraising options and futures contracts at the
last sale price on the market where such options or futures contracts are
principally traded, and (g) by appraising all other securities and other assets,
including debt securities for which prices are supplied by a pricing agent but
are not deemed by the Adviser to be representative of market values, but
excluding money market instruments with a remaining maturity of sixty days or
less and including restricted securities and securities for which no market
quotations are available, at fair value in accordance with procedures approved
by the Directors. 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 if their term to maturity at purchase
was 60 days or less, or by amortizing the difference between market value on the
61st day prior to maturity and value on maturity date if their original term to
maturity at purchase exceeded 60 days.
 
Events affecting the values of certain portfolio securities that occur between
the close of trading on the principal market for such securities (foreign
exchanges and over-the-counter markets) and the regular close of the Exchange
will not be reflected in the Portfolios' calculations of net asset values unless
the Adviser believes that the particular event would materially affect net asset
value, in which case an adjustment would be made.
 
                                      (C)
 
FORWARD FOREIGN CURRENCY CONTRACTS. A forward foreign currency contract is an
agreement to buy or sell currencies of different countries on a specified future
date at a specified rate. During the period the forward contract is open,
changes in the value of the contract are recognized as unrealized gains or
losses by "marking to market" such contract on a daily basis to
 
                                       142
<PAGE>   143
                                                   MAINSTAY VP SERIES FUND, INC.
 
reflect the market value of the contract at the end of each day's trading. When
the forward contract is closed, the Portfolio records a realized gain or loss
equal to the difference between the proceeds from (or cost of) the closing
transaction and the Portfolio's basis in the contract. The High Yield Corporate
Bond, International Equity and Value Portfolios enter into forward foreign
currency contracts in order to hedge their foreign currency denominated
investments and receivables and payables against adverse movements in future
foreign exchange rates.
 
The use of forward contracts involves, to varying degrees, elements of market
risk in excess of the amount recognized in the statement of assets and
liabilities. The contract amount reflects the extent of the Portfolio's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. The
unrealized appreciation (depreciation) on forward contracts reflects the
Portfolio's exposure at year-end to credit loss in the event of a counterparty's
failure to perform its obligations.

                                      (D)
 
FUTURES CONTRACTS. A futures contract is an agreement to purchase or sell a
specified quantity of an underlying instrument at a specified future date and
price, or to make or receive a cash payment based on the value of a securities
index. During the period the futures contract is open, changes in the value of
the contract are recognized as unrealized gains or losses by "marking to market"
such contract on a daily basis to reflect the market value of the contract at
the end of each day's trading. The Portfolio agrees to receive from or pay to
the broker an amount of cash equal to the daily fluctuation in the value of the
contract. Such receipts or payments are known as "variation margin". When the
futures contract is closed, the Portfolio records a realized gain or loss equal
to the difference between the proceeds from (or cost of) the closing transaction
and the Portfolio's basis in the contract. The Indexed Equity Portfolio invests
in stock index futures contracts to gain full exposure to changes in stock
market prices to fulfill its investment objective.
 
The use of futures contracts involves, to varying degrees, elements of market
risk in excess of the amount recognized in the statement of assets and
liabilities. The contract or notional amounts and variation margin reflect the
extent of the Portfolio's involvement in open futures positions. Risks arise
from the possible imperfect correlation in movements in the price of futures
contracts and the underlying hedged assets, and the possible inability of
counterparties to meet the terms of their contracts. However, the Portfolio's
activities in futures contracts are conducted through regulated exchanges which
minimize counterparty credit risks.
 
                                      (E)
 
REPURCHASE AGREEMENTS. At the time a Portfolio enters into a repurchase
agreement, the value of the underlying security, including accrued interest,
will be equal to or exceed the value of the repurchase agreement and, in the
case of repurchase agreements exceeding one day, the value of the underlying
security, including accrued interest, is required during the term of the
agreement to be equal to or exceed the value of the repurchase agreement. The
underlying securities for all repurchase agreements are held in a segregated
account of the respective Portfolio's custodian. In the case of repurchase
agreements exceeding one day, the market value of the underlying securities are
monitored by the Adviser by pricing them daily. (Also see Note 5).
 
                                      (F)
 
SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method and include gains
and losses from repayments of principal on mortgage related and other
asset-backed securities. Dividend income is recognized on the ex-dividend date
and interest income is accrued daily except when collection is not expected.
Discounts on securities purchased for all Portfolios are accreted on the
constant yield method over the life of the respective securities or, if
applicable, over the period to the first call date. Premiums on securities
purchased are not amortized for any Portfolio except Cash Management Portfolio
which amortizes the premium on the constant yield method over the life of the
respective securities.

FOREIGN CURRENCY INVESTING. The books and records of the Fund are recorded in
U.S. dollars. Foreign currency amounts are translated into U.S. dollars at the
mean between the buying and selling rates last quoted by any major U.S. bank at
the following dates:
 
        (i) market value of investment securities, other assets and
       liabilities--at the valuation date,
 
       (ii) purchases and sales of investment securities, income and
       expenses--at the date of such transactions.
 
The assets and liabilities of High Yield Corporate Bond and International Equity
Portfolios are presented at the exchange rates and market values at the close of
the year. The changes in net assets arising from fluctuations in exchange rates
and the changes in net assets resulting from changes in market prices are not
separately presented. However, gains and losses from certain foreign currency
transactions are treated as ordinary income for Federal income tax purposes.
 
Net realized gain (loss) on foreign currency transactions represents net gains
and losses on forward currency contracts, net currency gains or losses realized
as a result of differences between the amounts of securities sale proceeds or
purchase cost, dividends, interest and withholding taxes recorded on the
Portfolio's books and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing foreign currency denominated
assets and liabilities, other than investments, at year-end exchange rates are
reflected in unrealized foreign exchange gains (losses).

MORTGAGE DOLLAR ROLLS. Certain of the Portfolios enter into mortgage dollar roll
transactions ("MDRs") in which they sell mortgage backed securities ("MBS") from
their portfolio to a counterparty from whom they simultaneously agree to buy a
similar security on a delayed delivery basis. The MDR transactions of the
Portfolios are classified as purchase and sale transactions. The securities sold
in connection with the MDRs are removed from the portfolio and a realized gain
or loss is recognized. The securities the Portfolios have agreed to acquire are
included at market value in the portfolio of investments and liabilities for
such purchase commitments are included as payables for investments purchased.
The Portfolios maintain a segregated account with the custodian containing
securities from the respective portfolios having a value not less than the
repurchase price, including accrued interest. MDR transactions involve certain
risks, including the risk that the MBS

RESTRICTED SECURITIES. A restricted security is a security which has been
purchased through a private offering and cannot be resold to the general public
without prior registration under the Securities Act of 1933. Disposal of these
securities may involve time-consuming negotiations and expense, and prompt sale
at an acceptable price may be difficult. The issuers of the securities will bear
the costs involved in registration under the Securities Act of 1933 and in
connection with the disposition of such securities. The Convertible, High Yield
Corporate Bond and Total Return Portfolios do not have the right to demand that
such securities be registered. The Portfolios may not invest more than 15%, 10%
and 15%, respectively, of their net assets in illiquid securities.

SECURITIES LENDING. The Portfolios may lend their securities to broker-dealers
and financial institutions. The loans are secured by collateral (cash or
securities) at least equal at all times to the market value of the securities
loaned. The Portfolios may bear the risk of delay in recovery of, or loss of
rights in, the securities loaned should the borrower of the securities fail
financially. The Portfolios receive compensation for lending their securities in
the form of fees or they retain a portion of interest on the investment of any
cash received as collateral. The Portfolios also continue to receive interest
and dividends on the securities loaned, and any gain or loss in the market price
of the securities loaned that may occur during the term of the loan will be for
the account of the Portfolios.

PURCHASED AND WRITTEN OPTIONS. International Equity Portfolio may write covered
call and put options on its portfolio securities or foreign currencies. Premiums
are received and are recorded as liabilities. The liabilities are subsequently
adjusted to reflect the current value of the options written. Premiums received
from writing options which expire are treated as realized gains. Premiums
received from writing options which are exercised or are canceled in closing
purchase transactions are added to the proceeds or netted against the amount
paid on the transaction to determine the realized gain or loss. By writing a
covered call option, a Portfolio foregoes in exchange for the premium the
opportunity for capital appreciation above the exercise price should the market
price of the underlying security or foreign currency increase. By writing a
covered put option, a Portfolio, in exchange for the premium, accepts the risk
of a decline in the market value of the underlying security or foreign currency
below the exercise price.
 
The Portfolio may purchase call and put options on its portfolio securities or
foreign currencies. The Portfolio may purchase call options to protect against
an increase in the price of the security or foreign currency it anticipates
purchasing. The Portfolio may purchase put options on its securities or foreign
currencies to protect against a decline in the value of the security or foreign
currency or to close out covered written put positions. Risks may arise from an
imperfect correlation between the change in market value of the securities or
foreign currencies held by the Portfolio and the prices of options relating to
the securities or foreign currencies purchased or sold by the Portfolio and from
the possible lack of a liquid secondary market for an option. The maximum
exposure to loss for any purchased option is limited to the premium initially
paid for the option.

FINANCIAL INSTRUMENTS WITH CONCENTRATION OF CREDIT RISK. High Yield Corporate
Bond Portfolio invests in Loan Participations. When the Portfolio purchases a
Participation, the Portfolio typically enters into a contractual relationship
with the lender or third party selling such Participation ("Selling
Participant"), but not with the Borrower. As a result, the Portfolio assumes the
credit risk of the Borrower, the Selling Participant and any other persons
interpositioned between the Portfolio and the Borrower ("Intermediate
Participants"). The Portfolio may not directly benefit from the collateral
supporting the Senior Loan in which it has purchased the Participation. The
Portfolio may be considered to have a concentration of credit risk in the
banking industry, since the Portfolio will only acquire Participations if the
Selling Participant and each Intermediate Participant is a financial
institution.
 
                                      (N)
 
FEDERAL INCOME TAXES. Each of the Portfolios is treated as a separate entity for
Federal income tax purposes. The Fund's policy is to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of the taxable income to the shareholders of
each Portfolio within the allowable time limits. Therefore, no Federal income
tax provision is required.
 
Investment income received by a Portfolio from foreign sources may be subject to
foreign income taxes withheld at the source.
 
                                      (O)
 
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. For Cash Management Portfolio, dividends are
declared daily and paid monthly. Each of the other Portfolios intends to declare
and pay, as a dividend, substantially all of their net investment income and net
realized gains no less frequently than once a year. Income dividends and capital
gain distributions are determined in accordance with Federal tax regulations
which may differ from generally accepted accounting principles. These "book/tax
differences" are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the capital accounts based on their Federal tax basis treatment;
temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for financial reporting purposes but not for Federal tax purposes are reported
as dividends in excess of net investment income or distributions in excess of
net realized capital gains.

</TABLE>
 
The reclassifications for the Portfolios are primarily due to foreign currency
gain (loss), nondeductible organization expenses, distributions in excess of net
investment income, gain on sales of passive foreign investment companies,
investments in real estate investment trusts, paydown gain (loss), and net
operating losses.
 
                                      (Q)
 
EXPENSES. Expenses with respect to the Fund are allocated to the individual
Portfolios in proportion to the net assets of the respective Portfolios when the
expenses are incurred except when direct allocations of expenses can be made.
 
                                      (R)
 
USE OF ESTIMATES. The preparation of financial statements in accordance with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts and disclosures in the
financial statements. Actual results could differ from those estimates.

NOTE 5--Financial Investments:
- --------------------------------------------------------------------------------
 
High Yield Corporate Bond Portfolio invests primarily in high yield bonds. These
bonds may involve special risks in addition to the risks associated with
investment in higher rated debt securities. High yield bonds may be more
susceptible to real or perceived adverse economic and competitive industry
conditions than higher grade bonds. Also, the secondary market on which high
yield bonds are traded may be less liquid than the market for higher grade
bonds.
 
Each Portfolio may enter into repurchase agreements to earn income. In the event
of the bankruptcy of the seller or the failure of the seller to repurchase the
securities as agreed, a Portfolio could suffer losses, including loss of
interest on or principal of the security and costs associated with delay and
enforcement of the repurchase agreement.
 
- --------------------------------------------------------------------------------
NOTE 6--Portfolio Securities Loaned:
- --------------------------------------------------------------------------------
 
At December 31, 1998, Government and Total Return Portfolios had portfolio
securities with a fair market value of $27,373,061 and $76,256,517, respectively
on loan to broker-dealers and government securities dealers.
 
Cash collateral received by Government and Total Return Portfolios is invested
in investment grade commercial paper, or other securities in accordance with the
Portfolios securities lending procedures. Such investments are included as an
asset and a corresponding liability in the Statement of Assets and Liabilities.
While the Portfolios invest cash collateral in investment grade securities or
other "high quality" investment vehicles, the Portfolios bear the risk that
liability for the collateral may exceed the value of the investment.

REPORT OF INDEPENDENT ACCOUNTANTS
- --------------------------------------------------------------------------------
To the Board of Directors and Shareholders of
MainStay VP 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 Capital Appreciation Portfolio,
Cash Management Portfolio, Convertible Portfolio, Government Portfolio, High
Yield Corporate Bond Portfolio, International Equity Portfolio, Total Return
Portfolio, Value Portfolio, Bond Portfolio, Growth Equity Portfolio, and Indexed
Equity Portfolio (eleven of the fifteen portfolios constituting MainStay VP
Series Fund, Inc., hereafter referred to as the "Fund") at December 31, 1998,
and the results of their operations for the year then ended, and the changes in
their net assets and the financial highlights for each of the periods indicated,
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, 1998 by
correspondence with the custodians and brokers, provide a reasonable basis for
the opinion expressed above.
