PRINCIPAL INVESTMENT
STRATEGIES

                        -       The Global Equity Portfolio invests primarily in
                                equity securities on a worldwide basis and may
                                invest in U.S. or foreign fixed income
                                securities.

                        -       The Managed Portfolio invests in common stocks,
                                bonds and cash equivalents, allocated based on
                                the investment adviser's judgment.


INVESTMENT
PHILOSOPHY              OpCap Advisors is the investment adviser to all of the
                        Portfolios. OpCap Advisors has retained Pacific
                        Investment Management Company ("PIMCO") as sub-adviser
                        for a portion of the assets of the Managed Portfolio.

                        For the equity investments it manages directly, i.e.,
                        the Global Equity Portfolio and the portion of the
                        assets of the Managed Portfolio not sub-advised by its
                        affiliates, OpCap Advisors applies principles of value
                        investing, although the individual portfolio managers
                        may implement those principles differently.

                        When selecting equity securities, OpCap Advisors
                        believes there are two major components of value.

                        -       A company's ability to generate earnings that
                                contribute to shareholder value. OpCap Advisors
                                considers discretionary cash flow-cash that
                                remains after a company spends what is needed to
                                sustain its industrial position as a primary
                                determinant of a company's potential to add
                                economic value.

                        -       Price - OpCap Advisors looks for market
                                undervaluation great enough to offer the
                                potential for upside reward with what it
                                believes is modest downward risk.

                        OpCap Advisors uses fundamental company analysis to
                        select securities. Fundamental company analysis involves
                        intensive evaluation of historic financial data
                        including:


                                       3
<PAGE>

                        -       Company financial statements
                        -       Market share analysis
                        -       Unit volume growth
                        -       Barriers to entry
                        -       Pricing policies
                        -       Management record.

                        OpCap Advisors uses fundamental company analysis to
                        select companies they believe have one or more of the
                        following characteristics:

                        -       substantial and growing discretionary cash flow
                        -       strong shareholder value-oriented management
                        -       valuable consumer or commercial franchises
                        -       high returns on capital
                        -       favorable price to intrinsic value relationship.

                        In selecting debt securities, OpCap Advisors analyzes
                        yield relationships between different sectors and among
                        securities along the yield curve. OpCap Advisors seeks
                        to take advantage of maturities and individual issues
                        that are inexpensive and have the potential to provide
                        superior returns. In evaluating high yield debt
                        securities, OpCap Advisors supplements its traditional
                        credit analysis with an evaluation of an issuer's asset
                        values.

                        There can be no assurance that OpCap Advisors will
                        achieve its goals.

                        PIMCO acts as the sub-adviser to the Managed Portfolio.
                        In selecting securities for the Managed Portfolio, PIMCO
                        develops an outlook for interest rates, currency
                        exchange rates and the economy; analyzes credit and call
                        risks, and uses other security selection techniques. The
                        proportion of the Portfolio's assets committed to
                        investment in securities with particular characteristics
                        (such as quality, section interest rate or maturity)
                        varies based on PIMCO's outlook for the U.S. economy and
                        the economies of other countries in the world, the
                        financial markets and other factors.

                        PIMCO attempts to identify areas of the bond market that
                        are undervalued relative to the rest of the market.
                        PIMCO identifies these areas by grouping bonds into the
                        following sectors: money markets, governments,
                        corporates, mortgages, asset-backed and international.
                        Sophisticated proprietary software then assists in
                        evaluating sectors and pricing specific securities. Once
                        investment opportunities are identified, PIMCO will
                        shift assets among sectors

                        depending upon changes in relative valuations and credit
                        spreads. There is no guarantee that PIMCO's security
                        selection techniques will produce the desired results.

PRINCIPAL RISKS         If you invest in the Portfolios that invest in equity
                        securities, you could lose money or those Portfolios
                        could underperform other investments if any of the
                        following happens:

                        -       The stock market goes down
                        -       The Portfolio's investment style (i.e., value or
                                growth) falls out of favor with the stock market
                        -       The Portfolio's investment sector (e.g., small
                                cap, mid cap or foreign securities, which
                                generally are more volatile than U.S. large cap
                                securities) declines or becomes less liquid
                        -       For the Global Equity and Managed Portfolios,
                                the market undervalues the stocks held for
                                longer than expected, or the stocks purchased
                                turn out not to be undervalued
                        -       The stocks selected for growth potential do not
                                achieve such growth.

                        If you invest in the Portfolios that invest in debt
                        securities, you could lose money or your investment may
                        underperform other investments if any of the following
                        happens:

                        -       Interest rates rise and the bond market goes
                                down
                        -       Issuers of debt instruments cannot meet their
                                obligations
                        -       Bond issuers' call bonds selling at a premium to
                                their call price before the maturity date
                        -       Loans securing mortgage-backed obligations
                                prepay principal more rapidly than expected. The
                                Portfolios may have to reinvest these
                                prepayments at lower rates.

BAR CHART &
PERFORMANCE
TABLE
                        The bar charts provide some indication of the risks of
                        investing in the Portfolios by showing changes in the
                        performance of each Portfolio's shares from year to year
                        for the life of each Portfolio and the highest and
                        lowest quarterly return during the life of each
                        Portfolio.

                        The Portfolios' past performance does not necessarily
                        indicate how each Portfolio will perform in the future.
                        The Portfolios' performance does not reflect charges and
                        deductions which are imposed under the variable
                        contracts.

A    Foreign securities provide additional opportunities and diversification.
     U.S. stocks represent less than half of the world's stock market
     capitalization.


MANAGED PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Growth of capital over time through investment in a portfolio consisting of
     common stocks, bonds and cash equivalents, the percentages of which will
     vary based on OpCap Advisors' and PIMCO's assessments of the relative
     outlook for such investments.

Q    What is the Portfolio's investment program?

A    The Portfolio seeks to meet its objective by investing in common stocks,
     bonds and cash equivalents in varying percentages based on OpCap Advisors'
     and PIMCO's view of relative values. The Portfolio may purchase securities
     listed on U.S. or foreign securities exchanges or traded in the U.S. or
     foreign over the counter markets. The Portfolio also may purchase
     investment grade U.S. government and corporate bonds and high quality money
     market securities. The Portfolio can invest up to 100% of its assets in
     debt securities but will only do so if equity securities are not an
     attractive investment.

Q    What are the potential rewards of investing in the Portfolio?

A    The Portfolio normally invests mainly in equity securities. Common stocks
     offer a way to invest for long term growth of capital.


                                      RISKS

Q    What are the risks of investing in the Portfolios?

A    The Global Equity and the Managed Portfolios invest principally in equity
     securities which may be affected by the following:

     STOCK MARKET VOLATILITY - The stock market in general may fluctuate in
     response to political, market and economic developments and you can lose
     money on your investments.

     Equity investors should have a long-term investment horizon and should be
     prepared for the ups and downs of the stock market.

     STOCK PICKING - The portfolio manager may select stocks that have prices
     that turn out not to be undervalued or do not achieve expectations for
     growth in income or revenues.

     ISSUER CHANGES - Changes in the financial condition of an issuer or changes
     in economic conditions that affect a particular type of issuer can affect
     the value or credit quality of an


                                       8
<PAGE>

     issuer's securities.

     SMALL CAP AND MID CAP VOLATILITY - Mid cap stocks are more volatile and
     have less trading volume than large cap stocks. Small cap stocks are more
     volatile and have less trading volume than both large cap and mid cap
     stocks.

     SECTOR RISK - OpCap Advisors are bottom up investment managers. That means
     that they select securities for a Portfolio based on the investment merits
     of a particular issue rather than the business sector.

     INVESTMENT STYLES - Value or growth stocks may be out of favor for a period
     of time. Both investment styles can produce poor returns for a period of
     time.

     ASSET ALLOCATION RISK - The Managed Portfolio invests in a mix of equity
     and fixed income securities. The portfolio manager of the Managed Portfolio
     can make the wrong allocation decisions.

     FOREIGN EXPOSURE - When selecting foreign securities for the Portfolios,
     OpCap Advisors use approximately the same standards that they set for U.S.
     issuers. Foreign securities, foreign currencies and securities issued by
     U.S. entities with substantial foreign operations may have additional risks
     than U.S. securities. This risk is greater for the Global Equity Portfolio
     which invests on a worldwide basis.

          -    Political Risk - Foreign governments can take over the assets or
               operations of a company or may impose taxes or limits on the
               removal of the Portfolio's assets from that country.

          -    Currency risk - The value of securities held in foreign
               currencies will be affected by changes in the value of that
               currency.

          -    Liquidity - Some foreign markets are less liquid and more
               volatile than the U.S. stock market.

          -    Limited information - There may be less public information about
               foreign issuers than there is about U.S. issuers.

          -    Settlement and clearance - Some foreign markets experience delays
               in settlement. These delays could cause the Portfolio to miss
               investment opportunities or to be unable to sell a security.

          -    Euro - The effect of the Euro on international markets has not
               yet been determined.

          -    Emerging Markets - There are greater risks of unstable
               governments and economies and restriction on foreign ownership in
               these countries. The Portfolios presently intend to limit
               investment in emerging markets to no more than 5% of their total
               assets.


                                       9
<PAGE>

To the extent that the Managed and Global Equity Portfolios invest in debt
securities, the Portfolios are exposed to these risks:

     -    Interest rate risk - The risk that changes in interest rates will
          affect the value of fixed income securities in the Portfolio.

     -    Prepayment risk - The risk that the holder of a mortgage underlying a
          mortgage backed security will prepay principal.

     -    Credit risk - The risk that an issuer of a fixed income security will
          be unable to pay principal and interest payments when they are due.

To the extent that the Global Equity Portfolio invests in lower grade debt
securities, you should know that lower grade debt may have the following
additional risks:

     -    more volatility

     -    less liquidity

     -    greater risk of issuer default or insolvency.


                               INVESTMENT POLICIES

Q    Can a Portfolio change its investment objective and investment policies?

A    Fundamental policies of a Portfolio cannot be changed without the approval
     of a majority of the outstanding voting shares of the Portfolio. A
     Portfolio's investment objective is a fundamental policy. Investment
     restrictions that are fundamental policies are listed in the Statement of
     Additional Information. Investment policies are not fundamental and can be
     changed by the Fund's Board of Trustees.

Q    Can the Portfolios use derivative instruments?

A    Yes. The Global Equity and Managed Portfolios may use the following
     derivative instruments:

     -    futures contracts
     -    options on futures contracts
     -    forward foreign currency contracts
     -    covered calls written on individual securities
     -    uncovered calls and puts
     -    options on stock indices.

     The Global Equity Portfolio does not expect to use derivative instruments
     significantly, if at


                                       10
<PAGE>

     all. The Managed Portfolio will sometimes use derivative instruments as
     part of a strategy designed to reduce exposure to other risks, such as
     interest risk or currency risk, and may use derivative instruments to meet
     their investment objectives.

Q    What are the risks of derivative instruments?

A    Derivative instruments can reduce the return of a Portfolio if :

     -    Its investment adviser uses a derivative instrument at the wrong time
     -    The prices of a Portfolio's futures or options positions are not
          correlated with its other investments
     -    A Portfolio cannot close out a position because of an illiquid market.

Q    Do the Portfolios expect to engage in short-term trading?

A    The Portfolios do not expect to engage in frequent short-term trading. The
     Financial Highlights table in this prospectus shows the turnover rates
     during prior fiscal years for the Portfolios that were active during this
     period.

Q    Can the Portfolios vary from their investment goals?

A    When a Portfolio's investment adviser or subadviser thinks market or
     economic conditions are adverse, it may invest up to 100% of its assets in
     defensive investments such as U.S. Government securities and money market
     instruments. To the extent that a Portfolio takes a defensive position, it
     will not be pursuing its investment objective.


                                 FUND MANAGEMENT

OPCAP ADVISORS

The Board of Trustees of the Fund has hired OpCap Advisors to serve as manager
of the Fund.

OpCap Advisors is a subsidiary of Oppenheimer Capital, an investment advisory
firm with approximately $53 billion of assets under management as of December
31, 1999. They are indirect wholly-owned subsidiaries of PIMCO Advisors L.P. The
mailing address is 1345 Avenue of the Americas, New York, New York 10105.

The general partners of PIMCO Advisors L.P. are PIMCO Partners G.P. and PIMCO
Advisors Holding L.P. ("PAH"). PIMCO Partners, G.P. is a general partnership
between PIMCO Holdings LLC, a Delaware limited liability company and an indirect
wholly-owned subsidiary of Pacific Life Insurance Company, and PIMCO Partners
LLC, a California limited liability company controlled by the current Managing
Directors and two former Managing Directors of Pacific Investment Management
Company, a subsidiary of PIMCO Advisors L.P. PIMCO Partners, G.P. is the sole
general partner of PAH.


                                       11

On October 31, 1999, PIMCO Advisors L.P., PAH and Allianz AG ("Allianz")
announced that they had reached a definitive agreement pursuant to which Allianz
will acquire majority ownership of PIMCO Advisors L.P. and its subsidiaries,
including OpCap Advisors (the "Allianz Transaction"). Under the terms of the
transaction, Allianz will acquire all of PAH, the publicly traded general
partner of PIMCO Advisors L.P. Pacific Life Insurance Company will retain an
approximately 30% interest in PIMCO Advisors L.P. The Allianz Transaction is
currently expected to be completed by on or about May 5, 2000.

Allianz is the world's second largest insurance company and a leading provider
of financial services, particularly in Europe, and is represented in 68
countries world-wide through subsidiaries, branch and representative offices,
and other affiliated entities. Allianz currently has assets under management of
more than $390 billion, and in its last fiscal year wrote approximately $50
billion in gross insurance premiums. After consummation of the transaction, the
combined firms will have over $650 billion in assets under management.

Affiliates of Allianz currently include Dresdner Bank AG, Deutsche Bank AG,
Munich Re, and Hypo Vereinsbank. These entities, as well as certain broker-
dealers controlled by or affiliated with these entities, such as Bankers Trust
Company and BT Alex Brown, Inc. are considered the "Affiliated Brokers." Once
the Allianz transaction is consummated, absent an SEC exemption or other relief,
the Fund's Portfolios would generally be precluded from effecting principal
transactions with the Affiliated Brokers, and each Portfolio's ability to
purchase securities being underwritten by an Affiliated Broker or to utilize the
Affiliated Brokers for agency transactions would be subject to restrictions.
OpCap Advisors does not believe that the restrictions on transactions with the
Affiliated Brokers described above will materially adversely affect its ability,
post-closing, to provide services to the Fund, the ability of the Portfolios to
take advantage of market opportunities, or the overall performance of the
Portfolios.

The consummation of the Allianz Transaction is subject to the approval of the
public unitholders of PAH, as well as to certain regulatory and client
approvals, and other conditions customary to transactions of this kind.

This Prospectus will be supplemented or revised if the Allianz Transaction does
not occur substantially as set forth above.

OpCap Advisors has been in business as an investment adviser since 1987 and
Oppenheimer Capital has been in business as an investment adviser since 1969.

OpCap Advisors manages the investments of certain Portfolios (and places
brokerage orders) and conducts the business affairs of the Fund. Employees of
Oppenheimer Capital, PIMCO Advisors and OpCap Advisors perform these services.

Each Portfolio pays OpCap Advisors fees in return for providing or arranging for
the provision of investment advisory services. OpCap also pays a portion of its
advisory fees to PIMCO in return for the advisory services PIMCO performs for
the Managed Portfolio. The Portfolios of the Fund listed below paid OpCap
Advisors the following fees as a percentage of average daily net assets during
the fiscal year ended December 31, 1999:

          Global Equity Portfolio........................................0.80%
          Managed Portfolio..............................................0.77%
</TABLE>

OpCap will pay PIMCO a fee at the annual rate of 0.25% of the average daily net
assets of the Managed Portfolio for the advisory services PIMCO performed for
the Managed Portfolio.

The Fund pays OpCap Advisors at the annual rate of .80% of the first $400
million of average net assets, .75% on the next $400 million of average net
assets and .70% of assets in excess of $800 million with respect to the Global
Equity and Managed Portfolios.

                                   SHARE PRICE

The Fund calculates each Portfolio's share price, called its net asset value, on
each business day that the New York Stock Exchange is open after the close of
regular trading (generally 4:00 p.m. Eastern Standard Time). Net asset value per
share is computed by adding up the total value of a Portfolio's investments and
other assets, subtracting its liabilities and then dividing by the number of
shares outstanding.

                               TOTAL PORTFOLIO ASSETS - LIABILITIES
          Net Asset Value =  ------------------------------------------
                               NUMBER OF PORTFOLIO SHARES OUTSTANDING

The Fund uses the market prices of securities to value a Portfolio's investments
unless securities do not have market quotations or are short-term debt
securities. When the Fund uses fair value to price a security, the Fund reviews
the pricing method with the Fund's Board. The Fund prices short-term investments
that mature in less than 60 days using amortized cost or amortized value.
Foreign securities trade on days when the Portfolios do not price their shares
so the net asset value of a Portfolio's shares may change on days when
shareholders will not be able to buy or sell shares of the Portfolio. If an
event occurs after the close of the New York Stock Exchange that the Fund
believes changes the value of a security, then the Fund will value the security
at what it believes to be fair value.


                             DISTRIBUTIONS AND TAXES

This discussion is about distributions to the Portfolio's shareholders, which
are variable accounts of insurance companies and qualified pension and
retirement plans. You should read the prospectus for the variable account for
information about distributions and federal tax treatment for contract owners of
variable products.

Each Portfolio pays dividends from its net investment income and distributes any
net capital gains that it has realized at least once a year.

INVESTMENT
PHILOSOPHY                          OpCap Advisors is the investment adviser to
                                    all of the Portfolios. OpCap Advisors has
                                    retained Pacific Investment Management
                                    Company ("PIMCO") as sub-adviser for a
                                    portion of the assets of the Managed
                                    Portfolio.

                                    For the equity investments it manages
                                    directly, i.e., the Equity, Small Cap and
                                    Global Equity Portfolios and the portion of
                                    the assets of the Managed Portfolios not
                                    sub-advised by its affiliates, OpCap
                                    Advisors applies principles of value
                                    investing, although the individual portfolio
                                    managers may implement those principles
                                    differently.

                                    When selecting equity securities, OpCap
                                    Advisors believes there are two major
                                    components of value.

                                    -   A company's ability to generate earnings
                                        that contribute to shareholder value.
                                        OpCap Advisors considers discretionary
                                        cash flow-cash that remains after a
                                        company spends what is

                                        needed to sustain its industrial
                                        position as a primary determinant of a
                                        company's potential to add economic
                                        value.

                                    -   Price - OpCap Advisors looks for market
                                        undervaluation great enough to offer the
                                        potential for upside reward with what it
                                        believes is modest downward risk.

                                    OpCap Advisors uses fundamental company
                                    analysis to select securities. Fundamental
                                    company analysis involves intensive
                                    evaluation of historic financial data
                                    including:

                                    - Company financial statements
                                    - Market share analysis
                                    - Unit volume growth
                                    - Barriers to entry
                                    - Pricing policies
                                    - Management record.

                                    OpCap Advisors uses fundamental company
                                    analysis to select companies they believe
                                    have one or more of the following
                                    characteristics:

                                    - substantial and growing discretionary cash
                                      flow
                                    - strong shareholder value-oriented
                                      management
                                    - valuable consumer or commercial franchises
                                    - high returns on capital
                                    - favorable price to intrinsic value
                                      relationship.

                                    In selecting debt securities, OpCap Advisors
                                    analyzes yield relationships between
                                    different sectors and among securities along

                                    Portfolio. In selecting securities for the
                                    Managed Portfolio, PIMCO develops an outlook
                                    for interest rates, currency exchange rates
                                    and the economy; analyzes credit and call

                                    varies based on PIMCO's outlook for the U.S.
                                    economy and the economies of other countries
                                    in the world, the financial markets and
                                    other factors.

                                    PIMCO attempts to identify areas of the bond
                                    market that are undervalued relative to the
                                    rest of the market. PIMCO identifies these
                                    areas by grouping bonds into the following
                                    sectors: money markets, governments,
                                    corporates, mortgages, asset-backed and
                                    international. Sophisticated proprietary
                                    software then assists in evaluating sectors
                                    and pricing specific securities. Once
                                    investment opportunities are identified,
                                    PIMCO will shift assets among sectors
                                    depending upon changes in relative
                                    valuations and credit spreads. There is no
                                    guarantee that PIMCO's security selection
                                    techniques will produce the desired results.

PRINCIPAL RISKS                     If you invest in the Portfolios that invest
                                    in equity securities, you could lose money
                                    or those Portfolios could underperform other
                                    investments if any of the following happens:

                                    -  The stock market goes down
                                    -  The Portfolio's investment style (i.e.,
                                       value or growth) falls out of favor with
                                       the stock market
                                    -  The Portfolio's investment sector (e.g.,
                                       small cap, mid cap or foreign securities,
                                       which generally are more volatile than
                                       U.S. large cap securities) declines or
                                       becomes less liquid
                                    -  For the Equity, Small Cap, Global Equity
                                       and Managed Portfolios, the market
                                       undervalues the stocks held for longer
                                       than expected, or the stocks purchased
                                       turn out not to be undervalued
                                    -  The stocks selected for growth potential
                                       do not achieve such growth.

                                    If you invest in the Portfolios that invest
                                    in debt securities, you could lose money or
                                    your investment may underperform other
                                    investments if any of the following happens:

                                    -  Interest rates rise and the bond market
                                       goes down
                                    -  Issuers of debt instruments cannot meet
                                       their obligations
                                    -  Bond issuers' call bonds selling at a
                                       premium to their call price before the
                                       maturity date
                                    -  Loans securing mortgage-backed
                                       obligations prepay principal more rapidly
                                       than expected. The Portfolios may have to
                                       reinvest these prepayments at lower
                                       rates.

BAR CHART &
PERFORMANCE
TABLE
                     The bar charts provide some indication of the risks of
                     investing in the Portfolios by showing changes in the
                     performance of each Portfolio's shares from year to year
                     for the life of each Portfolio and the highest and lowest
                     quarterly return during the life of each Portfolio.

                     The Portfolios' past performance does not necessarily
                     indicate how each Portfolio will perform in the future. The
                     Portfolios' performance does not reflect charges and
                     deductions which are imposed under the variable contracts.

*On September 16, 1994, an investment company then called Quest for Value
Accumulation Trust (the "Old Trust") was effectively divided into two investment
funds, the Old Trust and the Fund, at which time the Fund commenced operations.
The total net assets for each of the Equity, Small Cap and Managed Portfolios
immediately after the transaction were $86,789,755, $139,812,573 and
$682,601,380, respectively, with respect to the Old Trust and for each of the
Equity, Small Cap and Managed Portfolios, $3,764,598, $8,129,274 and
$51,345,102, respectively, with respect to the Fund. For the period prior to
September 16, 1994, the performance figures above for each of the Equity, Small
Cap and Managed Portfolios reflect the performance of the corresponding
Portfolios of the Old Trust. The Old Trust commenced operations on August 1,
1988.

The benchmark for the portion of the Managed Portfolio managed by PIMCO is the
Lehman Brothers Aggregate Bond Index.

A    The Equity Portfolio invests primarily in equity securities of companies
     that OpCap Advisors believes are undervalued in the marketplace. Under
     normal conditions, the Portfolio will invest at least 65% of its total
     assets in equity securities listed on the New York Stock Exchange. The
     Portfolio also may purchase securities listed on other U.S. or foreign
     securities exchanges or traded in the U.S. or foreign over the counter
     markets.

     The Equity Portfolio is managed to follow a composite portfolio constructed
     by a group of senior portfolio managers at OpCap Advisors.

Q    What are the potential rewards of investing in the Portfolio?

A    Common stocks and other equity securities offer a way to invest for long
     term growth of capital. Equity investors should have a long term investment
     horizon and should be prepared for the ups and downs of the stock markets.

     market capitalizations under $1 billion at the time of purchase that OpCap
     Advisors believes are undervalued in the marketplace. The Portfolio may
     purchase securities listed on U.S. or foreign securities exchanges or
     traded in the U.S. or foreign over the counter markets. The Portfolio also
     may purchase securities in initial public offerings or shortly after those
     offerings have been completed.

Q    What are the potential rewards of investing in the Portfolio?

A    Common stocks offer a way to invest for long term growth of capital.
     Opportunities for value creation for small cap companies could result from
     product expansion or product improvement, industry transition, new
     management or sale of the company. Small cap companies are followed by
     fewer analysts than are large and mid cap companies. So as additional
     analysts follow a small cap stock, investor demand for the stock may
     increase.


GLOBAL EQUITY PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Long term capital appreciation through pursuit of a global investment
     strategy primarily


                                         9
<PAGE>

     involving equity securities.

Q    What is the Portfolio's investment program?

A    The Portfolio invests primarily in equity securities of companies located
     throughout the world which OpCap Advisors believes are undervalued in the
     marketplace. The Portfolio may invest up to 35% of its total assets in
     fixed income securities which may be lower than investment grade.

Q    What are the potential rewards of investing in the Portfolio?

A    Foreign securities provide additional opportunities and diversification.
     U.S. stocks represent less than half of the world's stock market
     capitalization.


MANAGED PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Growth of capital over time through investment in a portfolio consisting of
     common stocks, bonds and cash equivalents, the percentages of which will
     vary based on OpCap Advisors' and PIMCO's assessments of the relative
     outlook for such investments.

Q    What is the Portfolio's investment program?

A    The Portfolio seeks to meet its objective by investing in common stocks,
     bonds and cash equivalents in varying percentages based on OpCap Advisors'
     and PIMCO's view of relative values. The Portfolio may purchase securities
     listed on U.S. or foreign securities exchanges or traded in the U.S. or
     foreign over the counter markets. The Portfolio also may purchase
     investment grade U.S. government and corporate bonds and high quality money
     market securities. The Portfolio can invest up to 100% of its assets in
     debt securities but will only do so if equity securities are not an
     attractive investment.

Q    What are the potential rewards of investing in the Portfolio?

A    The Portfolio normally invests mainly in equity securities. Common stocks
     offer a way to invest for long term growth of capital.


                                      RISKS

Q    What are the risks of investing in the Portfolios?

A    The Equity, Small Cap, Global Equity and Managed Portfolios invest
     principally in equity securities which may be affected by the following:


                                         10
<PAGE>

     STOCK MARKET VOLATILITY - The stock market in general may fluctuate in
     response to political, market and economic developments and you can lose
     money on your investments.

     Equity investors should have a long-term investment horizon and should be
     prepared for the ups and downs of the stock market.

     STOCK PICKING - The portfolio manager may select stocks that have prices
     that turn out not to be undervalued or do not achieve expectations for
     growth in income or revenues.

     ISSUER CHANGES - Changes in the financial condition of an issuer or changes
     in economic conditions that affect a particular type of issuer can affect
     the value or credit quality of an issuer's securities.

     SMALL CAP AND MID CAP VOLATILITY - Mid cap stocks are more volatile and
     have less trading volume than large cap stocks. Small cap stocks are more
     volatile and have less trading volume than both large cap and mid cap
     stocks.

     SECTOR RISK - OpCap Advisors are bottom up investment managers. That means
     that they select securities for a Portfolio based on the investment merits
     of a particular issue rather than the business sector.

     INVESTMENT STYLES - Value or growth stocks may be out of favor for a period
     of time. Both investment styles can produce poor returns for a period of
     time.

     ASSET ALLOCATION RISK - The Managed Portfolio invests in a mix of equity
     and fixed income securities. The portfolio manager of the Managed Portfolio
     can make the wrong allocation decisions.

     FOREIGN EXPOSURE - When selecting foreign securities for the Portfolio,
     OpCap Advisors use approximately the same standards that they set for U.S.
     issuers. Foreign securities, foreign currencies and securities issued by
     U.S. entities with substantial foreign operations may have additional risks
     than U.S. securities. This risk is greater for the Global Equity Portfolio
     which invests on a worldwide basis.

         -    Political Risk - Foreign governments can take over the assets or
              operations of a company or may impose taxes or limits on the
              removal of the Portfolio's assets from that country.

         -    Currency risk - The value of securities held in foreign currencies
              will be affected by changes in the value of that currency.

         -    Liquidity - Some foreign markets are less liquid and more
              volatile than the U.S. stock market.

         -    Limited information - There may be less public information about
              foreign issuers than there is about U.S. issuers.


                                         11
<PAGE>

         -    Settlement and clearance - Some foreign markets experience delays
              in settlement. These delays could cause the Portfolio to miss
              investment opportunities or to be unable to sell a security.

         -    Euro - The effect of the Euro on international markets has not yet
              been determined.

         -    Emerging Markets - There are greater risks of unstable governments
              and economies and restriction on foreign ownership in these
              countries. The Portfolios presently intend to limit investment in
              emerging markets to no more than 5% of their total assets.

To the extent that the Portfolios invest in debt securities, the Portfolios are
exposed to these risks:

         -    Interest rate risk - The risk that changes in interest rates will
              affect the value of fixed income securities in the Portfolio.

         -    Prepayment risk - The risk that the holder of a mortgage
              underlying a mortgage backed security will prepay principal.

         -    Credit risk - The risk that an issuer of a fixed income security
              will be unable to pay principal and interest payments when they
              are due.

To the extent that the Global Equity Portfolio invests in lower grade debt
securities, you should know that lower grade debt may have the following
additional risks:

         -    more volatility

         -    less liquidity

         -    greater risk of issuer default or insolvency.


                               INVESTMENT POLICIES

Q    Can a Portfolio change its investment objective and investment policies?

A    Fundamental policies of a Portfolio cannot be changed without the approval
     of a majority of the outstanding voting shares of the Portfolio. A
     Portfolio's investment objective is a fundamental policy. Investment
     restrictions that are fundamental policies are listed in the Statement of
     Additional Information. Investment policies are not fundamental and can be
     changed by the Fund's Board of Trustees.

Q    Can the Portfolios use derivative instruments?


                                         12
<PAGE>

A    Yes. The Equity, Small Cap, Global Equity and Managed Portfolios may use
     the following derivative instruments:

     -   futures contracts
     -   options on futures contracts
     -   forward foreign currency contracts
     -   covered calls written on individual securities
     -   uncovered calls and puts
     -   options on stock indices.

     The Equity, Small Cap and Global Equity Portfolios do not expect to use
     derivative instruments significantly, if at all. The Managed Portfolio will
     sometimes use derivative instruments as part of a strategy designed to
     reduce exposure to other risks, such as interest risk or currency risk, and
     may use derivative instruments to meet their investment objectives.

Q    What are the risks of derivative instruments?

A    Derivative instruments can reduce the return of a Portfolio if :

     -   Its investment adviser uses a derivative instrument at the wrong time
     -   The prices of a Portfolio's futures or options positions are not
         correlated with its other investments
     -   A Portfolio cannot close out a position because of an illiquid market.

Q    Do the Portfolios expect to engage in short-term trading?

A    The Portfolios do not expect to engage in frequent short-term trading. The
     Financial Highlights table in this prospectus shows the turnover rates
     during prior fiscal years for the Portfolios that were active during this
     period.

Q    Can the Portfolios vary from their investment goals?

A    When a Portfolio's investment adviser or subadviser thinks market or
     economic conditions are adverse, it may invest up to 100% of its assets in
     defensive investments such as U.S. Government securities and money market
     instruments. To the extent that a Portfolio takes a defensive position, it
     will not be pursuing its investment objective.


                                 FUND MANAGEMENT

OPCAP ADVISORS

The Board of Trustees of the Fund has hired OpCap Advisors to serve as manager
of the Fund.

OpCap Advisors is a subsidiary of Oppenheimer Capital, an investment advisory
firm with approximately $53 billion of assets under management as of December
31, 1999. They are


                                         13
<PAGE>

indirect wholly-owned subsidiaries of PIMCO Advisors L.P. The mailing address is
1345 Avenue of the Americas, New York, New York 10105.

The general partners of PIMCO Advisors L.P. are PIMCO Partners G.P. and PIMCO
Advisors Holding L.P. ("PAH"). PIMCO Partners, G.P. is a general partnership
between PIMCO Holdings LLC, a Delaware limited liability company and an indirect
wholly-owned subsidiary of Pacific Life Insurance Company, and PIMCO Partners
LLC, a California limited liability company controlled by the current Managing
Directors and two former Managing Directors of Pacific Investment Management
Company, a subsidiary of PIMCO Advisors L.P. PIMCO Partners, G.P. is the sole
general partner of PAH.

On October 31, 1999, PIMCO Advisors L.P., PAH and Allianz AG ("Allianz")
announced that they had reached a definitive agreement pursuant to which Allianz
will acquire majority ownership of PIMCO Advisors L.P. and its subsidiaries,
including OpCap Advisors (the "Allianz Transaction"). Under the terms of the
transaction, Allianz will acquire all of PAH, the publicly traded general
partner of PIMCO Advisors L.P. Pacific Life Insurance Company will retain an
approximately 30% interest in PIMCO Advisors L.P. The Allianz Transaction is
currently expected to be completed by on or about May 5, 2000.

Allianz is the world's second largest insurance company and a leading provider
of financial services, particularly in Europe, and is represented in 68
countries world-wide through subsidiaries, branch and representative offices,
and other affiliated entities. Allianz currently has assets under management of
more than $390 billion, and in its last fiscal year wrote approximately $50
billion in gross insurance premiums. After consummation of the transaction, the
combined firms will have over $650 billion in assets under management.

Affiliates of Allianz currently include Dresdner Bank AG, Deutsche Bank AG,
Munich Re, and Hypo Vereinsbank. These entities, as well as certain broker-
dealers controlled by or affiliated with these entities, such as Bankers Trust
Company and BT Alex Brown, Inc. are considered the "Affiliated Brokers." Once
the Allianz transaction is consummated, absent an SEC exemption or other relief,
the Fund's Portfolios would generally be precluded from effecting principal
transactions with the Affiliated Brokers, and each Portfolio's ability to
purchase securities being underwritten by an Affiliated Broker or to utilize the
Affiliated Brokers for agency transactions would be subject to restrictions.
OpCap Advisors does not believe that the restrictions on transactions with the
Affiliated Brokers described above will materially adversely affect its ability,
post-closing, to provide services to the Fund, the ability of the Portfolios to
take advantage of market opportunities, or the overall performance of the
Portfolios.

The consummation of the Allianz Transaction is subject to the approval of the
public unitholders of PAH, as well as to certain regulatory and client
approvals, and other conditions customary to transactions of this kind.

This Prospectus will be supplemented or revised if the Allianz Transaction does
not occur substantially as set forth above.

OpCap Advisors has been in business as an investment adviser since 1987 and
Oppenheimer

Capital has been in business as an investment adviser since 1969.

OpCap Advisors manages the investments of certain Portfolios (and places
brokerage orders) and conducts the business affairs of the Fund. Employees of
Oppenheimer Capital, PIMCO Advisors and OpCap Advisors perform these services.

Each Portfolio pays OpCap Advisors fees in return for providing or arranging for
the provision of investment advisory services. OpCap also pays a portion of its
advisory fees to PIMCO in return for the advisory services PIMCO performs for
the Managed Portfolio. The Portfolios of the Fund listed below paid OpCap
Advisors the following fees as a percentage of average daily net assets during
the fiscal year ended December 31, 1999:

<TABLE>
                <S>                                             <C>
                Equity Portfolio................................0.80%
                Small Cap Portfolio.............................0.80%
                Global Equity Portfolio.........................0.80%
                Managed Portfolio...............................0.77%
</TABLE>

OpCap will pay PIMCO a fee at the annual rate of 0.25% of the average daily net
assets of the Managed Portfolio for the advisory services PIMCO performed for
the Managed Portfolio.

The Fund pays OpCap Advisors at the annual rate of .80% of the first $400
million of average net assets, .75% on the next $400 million of average net
assets and .70% of assets in excess of $800 million with respect to the Equity,
Global Equity, Managed and Small Cap Portfolios.

                                   SHARE PRICE

The Fund calculates each Portfolio's share price, called its net asset value, on
each business day that the New York Stock Exchange is open after the close of
regular trading (generally 4:00 p.m. Eastern Standard Time). Net asset value per
share is computed by adding up the total value of a Portfolio's investments and
other assets, subtracting its liabilities and then dividing by the number of
shares outstanding.

                                TOTAL PORTFOLIO ASSETS - LIABILITIES
           Net Asset Value =  ------------------------------------------
                                NUMBER OF PORTFOLIO SHARES OUTSTANDING

The Fund uses the market prices of securities to value a Portfolio's investments
unless securities do not have market quotations or are short-term debt
securities. When the Fund uses fair value to price a security, the Fund reviews
the pricing method with the Fund's Board. The Fund prices short-term investments
that mature in less than 60 days using amortized cost or amortized value.
Foreign securities trade on days when the Portfolios do not price their shares
so the net asset value of a Portfolio's shares may change on days when
shareholders will not be able to buy or sell shares of the Portfolio. If an
event occurs after the close of the New York Stock Exchange that the Fund
believes changes the value of a security, then the Fund will value the security
at what it believes to be fair value.


                             DISTRIBUTIONS AND TAXES

This discussion is about distributions to the Portfolio's shareholders, which
are variable accounts of insurance companies and qualified pension and
retirement plans. You should read the prospectus for the variable account for
information about distributions and federal tax treatment for contract owners of
variable products.

Each Portfolio pays dividends from its net investment income and distributes any
net capital gains that it has realized at least once a year.


                              FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the
Portfolio's financial performance. Certain information reflects financial
results for a single Portfolio share. The total returns in the table represent
the rate that an investor would have earned (or lost) on an investment in a
Portfolio (assuming reinvestment of all dividends and distributions). The
information in the financial highlights table below has been audited by
PricewaterhouseCoopers LLP, independent accountants, whose report, along with
the Portfolio's financial statements, is incorporated by reference in the Fund's

PRINCIPAL INVESTMENT
STRATEGIES                     -   The Equity Portfolio invests primarily in
                                   equity securities listed on the New York
                                   Stock Exchange.


INVESTMENT
PHILOSOPHY

                               OpCap Advisors is the investment adviser to the
                               Portfolio.

                               OpCap Advisors applies principles of value
                               investing, although the individual portfolio
                               manager may implement those principles
                               differently.

                               When selecting equity securities, OpCap Advisors
                               believes there are two major components of value.

                               -   A company's ability to generate earnings that
                                   contribute to shareholder value. OpCap
                                   Advisors considers discretionary cash
                                   flow-cash that remains after a company spends
                                   what is needed to sustain its industrial
                                   position as a primary determinant of a
                                   company's potential to add economic value.

                               -   Price - OpCap Advisors looks for market
                                   undervaluation great enough to offer the
                                   potential for upside reward with what it
                                   believes is modest downward risk.

                               OpCap Advisors uses fundamental company analysis
                               to select securities. Fundamental company
                               analysis involves intensive evaluation of
                               historic financial data including:

                               -   Company financial statements
                               -   Market share analysis
                               -   Unit volume growth
                               -   Barriers to entry
                               -   Pricing policies
                               -   Management record.

                               OpCap Advisors uses fundamental company analysis
                               to select companies they believe have one or more
                               of the following characteristics:

                               -   substantial and growing discretionary cash
                                   flow

                                   3
<PAGE>

                               -   strong shareholder value-oriented management

                               -   valuable consumer or commercial franchises

                               -   high returns on capital

                               -   favorable price to intrinsic value
                                   relationship.

                               In selecting debt securities, OpCap Advisors
                               analyzes yield relationships between different
                               sectors and among securities along the yield
                               curve. OpCap Advisors seeks to take advantage of
                               maturities and individual issues that are
                               inexpensive and have the potential to provide
                               superior returns. In evaluating high yield debt
                               securities, OpCap Advisors supplements its
                               traditional credit analysis with an evaluation of
                               an issuer's asset values.

                               There can be no assurance that OpCap Advisors
                               will achieve its goals.


PRINCIPAL RISKS                You could lose money in the Equity Portfolio or
                               the Portfolio could underperform other
                               investments if any of the following happens:

                               -   The stock market goes down

                               -   The Portfolio's investment style (i.e., value
                                   or growth) falls out of favor with the stock
                                   market

                               -   The Portfolio's investment sector (e.g.,

                               -   The market undervalues the stocks held for
                                   longer than expected, or the stocks purchased
                                   turn out not to be undervalued

                               -   The stocks selected for growth potential do
                                   not achieve such growth.

                               You could lose money on your investment (to the
                               extent that the Portfolio invests in debt
                               securities) or your investment may underperform
                               other investments if any of the following
                               happens:

                               -   Interest rates rise and the bond market goes
                                   down

                               -   Issuers of debt instruments cannot meet their
                                   obligations

                               -   Bond issuers' call bonds selling at a premium
                                   to their call price before the maturity date

                               -   Loans securing mortgage-backed obligations
                                   prepay principal more rapidly than expected.
                                   The Portfolio may have to reinvest these
                                   prepayments at lower rates.

                        PRINCIPAL INVESTMENT STRATEGIES

EQUITY PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Long term capital appreciation through investment in a diversified
     portfolio of equity securities selected on the basis of a value approach to
     investing.

Q    What is the Portfolio's investment program?

A    The Equity Portfolio invests primarily in equity securities of companies
     that OpCap Advisors believes are undervalued in the marketplace. Under
     normal conditions, the Portfolio will invest at least 65% of its total
     assets in equity securities listed on the New York Stock Exchange. The
     Portfolio also may purchase securities listed on other U.S. or foreign
     securities exchanges or traded in the U.S. or foreign over the counter
     markets.

     The Equity Portfolio is managed to follow a composite portfolio constructed
     by a group of senior portfolio managers at OpCap Advisors.

Q    What are the potential rewards of investing in the Portfolio?

A    Common stocks and other equity securities offer a way to invest for long
     term growth of capital. Equity investors should have a long term investment
     horizon and should be prepared for the ups and downs of the stock markets.


                                      RISKS

Q    What are the risks of investing in the Portfolio?

A    The Equity Portfolio invests principally in equity securities which may be
     affected by the following:

     STOCK MARKET VOLATILITY - The stock market in general may fluctuate in
     response to political, market and economic developments and you can lose
     money on your investments.


                                       6
<PAGE>

     Equity investors should have a long-term investment horizon and should be
     prepared for the ups and downs of the stock market.

     STOCK PICKING - The portfolio manager may select stocks that have prices
     that turn out not to be undervalued or do not achieve expectations for
     growth in income or revenues.

     ISSUER CHANGES - Changes in the financial condition of an issuer or changes
     in economic conditions that affect a particular type of issuer can affect
     the value or credit quality of an issuer's securities.

     SMALL CAP AND MID CAP VOLATILITY - Mid cap stocks are more volatile and
     have less trading volume than large cap stocks. Small cap stocks are more
     volatile and have less trading volume than both large cap and mid cap
     stocks.

     SECTOR RISK - OpCap Advisors are bottom up investment managers. That means
     that they select securities for a Portfolio based on the investment merits
     of a particular issue rather than the business sector.

     INVESTMENT STYLES - Value or growth stocks may be out of favor for a period
     of time. Both investment styles can produce poor returns for a period of
     time.


     FOREIGN EXPOSURE - When selecting foreign securities for the Portfolio,
     OpCap Advisors use approximately the same standards that they set for U.S.
     issuers. Foreign securities, foreign currencies and securities issued by
     U.S. entities with substantial foreign operations may have additional risks
     than U.S. securities.

         -    Political Risk - Foreign governments can take over the assets or
              operations of a company or may impose taxes or limits on the
              removal of the Portfolio's assets from that country.

         -    Currency risk - The value of securities held in foreign currencies
              will be affected by changes in the value of that currency.

         -    Liquidity - Some foreign markets are less liquid and more volatile
              than the U.S. stock market.

         -    Limited information - There may be less public information about
              foreign issuers than there is about U.S. issuers.

         -    Settlement and clearance - Some foreign markets experience delays
              in settlement. These delays could cause the Portfolio to miss
              investment opportunities or to be unable to sell a security.

         -    Euro - The effect of the Euro on international markets has not yet
              been determined.

                                         7
<PAGE>

         -    Emerging Markets - There are greater risks of unstable governments
              and economies and restriction on foreign ownership in these
              countries. The Portfolio presently intends to limit investment in
              emerging markets to no more than 5% of its total assets.

To the extent that the Equity Portfolio invest in debt securities, the Portfolio
is exposed to these risks:

         -    Interest rate risk - The risk that changes in interest rates will
              affect the value of fixed income securities in the Portfolio.

         -    Prepayment risk - The risk that the holder of a mortgage
              underlying a mortgage backed security will prepay principal.

         -    Credit risk - The risk that an issuer of a fixed income security
              will be unable to pay principal and interest payments when they
              are due.


                            INVESTMENT POLICIES

Q   Can a Portfolio change its investment objective and investment policies?

A   Fundamental policies of a Portfolio cannot be changed without the approval
    of a majority of the outstanding voting shares of the Portfolio. A
    Portfolio's investment objective is a fundamental policy. Investment
    restrictions that are fundamental policies are listed in the Statement of
    Additional Information. Investment policies are not fundamental and can be
    changed by the Fund's Board of Trustees.

Q   Can the Portfolio use derivative instruments?

A   Yes. The Equity Portfolio may use the following derivative instruments:

     -   futures contracts
     -   options on futures contracts
     -   forward foreign currency contracts
     -   covered calls written on individual securities
     -   uncovered calls and puts
     -   options on stock indices.

     The Equity Portfolio does not expect to use derivative instruments
     significantly, if at all.

Q    What are the risks of derivative instruments?

A    Derivative instruments can reduce the return of a Portfolio if :

     -   Its investment adviser uses a derivative instrument at the wrong time
     -   The prices of a Portfolio's futures or options positions are not
         correlated with its other


                                     8
<PAGE>

         investments

     -   A Portfolio cannot close out a position because of an illiquid market.

Q    Does the Portfolio expect to engage in short-term trading?

A    The Portfolio do not expect to engage in frequent short-term trading. The
     Financial Highlights table in this prospectus shows the Portfolio's
     turnover rates during prior fiscal years.

Q    Can the Portfolio vary from their investment goals?

A    When a Portfolio's investment adviser or subadviser thinks market or
     economic conditions are adverse, it may invest up to 100% of its assets in
     defensive investments such as U.S. Government securities and money market
     instruments. To the extent that a Portfolio takes a defensive position, it
     will not be pursuing its investment objective.


                                 FUND MANAGEMENT

OPCAP ADVISORS

The Board of Trustees of the Fund has hired OpCap Advisors to serve as manager
of the Fund.

OpCap Advisors is a subsidiary of Oppenheimer Capital, an investment advisory
firm with approximately $53 billion of assets under management as of December
31, 1999. They are indirect wholly-owned subsidiaries of PIMCO Advisors L.P. The
mailing address is 1345 Avenue of the Americas, New York, New York 10105.

The general partners of PIMCO Advisors L.P. are PIMCO Partners G.P. and PIMCO
Advisors Holding L.P. ("PAH"). PIMCO Partners, G.P. is a general partnership
between PIMCO Holdings LLC, a Delaware limited liability company and an indirect
wholly-owned subsidiary of Pacific Life Insurance Company, and PIMCO Partners
LLC, a California limited liability company controlled by the current Managing
Directors and two former Managing Directors of Pacific Investment Management
Company, a subsidiary of PIMCO Advisors L.P. PIMCO Partners, G.P. is the sole
general partner of PAH.

On October 31, 1999, PIMCO Advisors L.P., PAH and Allianz AG ("Allianz")
announced that they had reached a definitive agreement pursuant to which Allianz
will acquire majority ownership of PIMCO Advisors L.P. and its subsidiaries,
including OpCap Advisors (the "Allianz Transaction"). Under the terms of the
transaction, Allianz will acquire all of PAH, the publicly traded general
partner of PIMCO Advisors L.P. Pacific Life Insurance Company will retain an
approximately 30% interest in PIMCO Advisors L.P. The Allianz Transaction is
currently expected to be completed by on or about May 5, 2000.

Allianz is the world's second largest insurance company and a leading provider
of financial services, particularly in Europe, and is represented in 68
countries world-wide through subsidiaries, branch and representative offices,
and other affiliated entities. Allianz currently has

                                    9
<PAGE>


assets under management of more than $390 billion, and in its last fiscal year
wrote approximately $50 billion in gross insurance premiums. After consummation
of the transaction, the combined firms will have over $650 billion in assets
under management.

Affiliates of Allianz currently include Dresdner Bank AG, Deutsche Bank AG,
Munich Re, and Hypo Vereinsbank. These entities, as well as certain broker-
dealers controlled by or affiliated with these entities, such as Bankers Trust
Company and BT Alex Brown, Inc. are considered the "Affiliated Brokers." Once
the Allianz transaction is consummated, absent an SEC exemption or other relief,
the Fund's Portfolios would generally be precluded from effecting principal
transactions with the Affiliated Brokers, and each Portfolio's ability to
purchase securities being underwritten by an Affiliated Broker or to utilize the
Affiliated Brokers for agency transactions would be subject to restrictions.
OpCap Advisors does not believe that the restrictions on transactions with the
Affiliated Brokers described above will materially adversely affect its ability,
post-closing, to provide services to the Fund, the ability of the Portfolios to
take advantage of market opportunities, or the overall performance of the
Portfolios.

The consummation of the Allianz Transaction is subject to the approval of the
public unitholders of PAH, as well as to certain regulatory and client
approvals, and other conditions customary to transactions of this kind.

This Prospectus will be supplemented or revised if the Allianz Transaction does
not occur substantially as set forth above.

OpCap Advisors has been in business as an investment adviser since 1987 and
Oppenheimer Capital has been in business as an investment adviser since 1969.

OpCap Advisors manages the investments of the Portfolio (and places brokerage
orders) and conducts the business affairs of the Fund. Employees of Oppenheimer
Capital, PIMCO Advisors and OpCap Advisors perform these services.

The Equity Portfolio paid OpCap Advisors fees in return for providing or
arranging for the provision of investment advisory services. The Equity
Portfolio of the Fund listed below paid OpCap Advisors the following fees as a
percentage of average daily net assets during the fiscal year ended December 31,
1999:

       Equity Portfolio..................................0.80%
</TABLE>

The Fund pays OpCap Advisors at the annual rate of .80% of the first $400
million of average net assets, .75% on the next $400 million of average net
assets and .70% of assets in excess of $800 million with respect to the Equity
Portfolio.

<PAGE>

                                SHARE PRICE

The Fund calculates the Portfolio's share price, called its net asset value, on
each business day that the New York Stock Exchange is open after the close of
regular trading (generally 4:00 p.m. Eastern Standard Time). Net asset value per
share is computed by adding up the total value of a Portfolio's investments and
other assets, subtracting its liabilities and then dividing by the number of
shares outstanding.

                          TOTAL PORTFOLIO ASSETS - LIABILITIES
     Net Asset Value =  --------------------------------------
                          NUMBER OF PORTFOLIO SHARES OUTSTANDING

The Fund uses the market prices of securities to value a Portfolio's investments
unless securities do not have market quotations or are short-term debt
securities. When the Fund uses fair value to price a security, the Fund reviews
the pricing method with the Fund's Board. The Fund prices short-term investments
that mature in less than 60 days using amortized cost or amortized value.
Foreign securities trade on days when the Portfolios do not price their shares
so the net asset value of a Portfolio's shares may change on days when
shareholders will not be able to buy or sell shares of the Portfolio. If an
event occurs after the close of the New York Stock Exchange that the Fund
believes changes the value of a security, then the Fund will value the security
at what it believes to be fair value.


                        DISTRIBUTIONS AND TAXES

This discussion is about distributions to the Portfolio's shareholders, which
are variable accounts of insurance companies and qualified pension and
retirement plans. You should read the prospectus for the variable account for
information about distributions and federal tax treatment for contract owners of
variable products.

The Portfolio pays dividends from its net investment income and distributes any
net capital gains that it has realized at least once a year.


                         FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the
Portfolio's financial performance. Certain information reflects financial
results for a single Portfolio share. The total returns in the table represent
the rate that an investor would have earned (or lost) on an investment in a
Portfolio (assuming reinvestment of all dividends and distributions). The
information in the financial highlights table below has been audited by
PricewaterhouseCoopers LLP, independent accountants, whose report, along with
the Portfolio's financial statements, is incorporated by reference in the Fund's
SAI, which is available upon request.

                               RISK/RETURN SUMMARY


INVESTMENT GOALS        Managed Portfolio............Growth of capital over time



PRINCIPAL INVESTMENT
STRATEGIES                   -  The Managed Portfolio invests in common stocks,
                                bonds and cash equivalents, allocated based on
                                the investment adviser's judgment.



INVESTMENT
PHILOSOPHY                   OpCap Advisors is the investment adviser to the
                             Portfolio. OpCap Advisors has retained Pacific
                             Investment Management Company ("PIMCO") as
                             sub-adviser for a portion of the assets of the
                             Managed Portfolio.

                             For the equity investments it manages directly,
                             i.e., the portion of the assets of the Managed
                             Portfolio not sub-advised by its affiliates, OpCap
                             Advisors applies principles of value investing,
                             although the individual portfolio manager may
                             implement those principles differently.

                             When selecting equity securities, OpCap Advisors
                             believes there are two major components of value.

                             -  A company's ability to generate earnings that
                                contribute to shareholder value. OpCap Advisors
                                considers discretionary cash flow-cash that
                                remains after a company spends what is needed to
                                sustain its industrial position as a primary
                                determinant of a company's potential to add
                                economic value.

                             -  Price - OpCap Advisors looks for market
                                undervaluation great enough to offer the
                                potential for upside reward with what it
                                believes is modest downward risk.

                             OpCap Advisors uses fundamental company analysis to
                             select securities. Fundamental company analysis
                             involves intensive evaluation of historic
                             financial data including:

                             -  Company financial statements
                             -  Market share analysis
                             -  Unit volume growth
                             -  Barriers to entry

                             -  Pricing policies
                             -  Management record.

                             OpCap Advisors uses fundamental company analysis to
                             select companies they believe have one or more
                             of the following characteristics:

                             -  substantial and growing discretionary cash flow
                             -  strong shareholder value-oriented management
                             -  valuable consumer or commercial franchises
                             -  high returns on capital
                             -  favorable price to intrinsic value relationship.

                             In selecting debt securities, OpCap Advisors
                             analyzes yield relationships between different
                             sectors and among securities along the yield curve.
                             OpCap Advisors seeks to take advantage of
                             maturities and individual issues that are
                             inexpensive and have the potential to provide
                             superior returns. In evaluating high yield debt
                             securities, OpCap Advisors supplements its
                             traditional credit analysis with an evaluation of
                             an issuer's asset values.

                             There can be no assurance that OpCap Advisors will
                             achieve its goals.

                             PIMCO acts as the sub-adviser to the Managed
                             Portfolio. In selecting securities for the Managed
                             Portfolio, PIMCO develops an outlook for interest
                             rates, currency exchange rates and the economy;
                             analyzes credit and call risks, and uses other
                             security selection techniques. The proportion of
                             the Portfolio's assets committed to investment in
                             securities with particular characteristics (such as
                             quality, section interest rate or maturity) varies
                             based on PIMCO's outlook for the U.S. economy and
                             the economies of other countries in the world, the
                             financial markets and other factors.

                             PIMCO attempts to identify areas of the bond market
                             that are undervalued relative to the rest of the
                             market. PIMCO identifies these areas by grouping
                             bonds into the following sectors: money markets,
                             governments, corporates, mortgages, asset-backed
                             and international. Sophisticated proprietary
                             software then assists in evaluating sectors and
                             pricing specific securities. Once investment
                             opportunities are identified, PIMCO will shift
                             assets among sectors depending upon changes in
                             relative valuations and credit spreads. There is no
                             guarantee that PIMCO's security selection
                             techniques will produce the desired results.

PRINCIPAL RISKS              You could lose money in the Managed Portfolio or
                             the Portfolio could underperform other investments
                             if any of the following happens:

                             -  The stock market goes down
                             -  The Portfolio's investment style (i.e., value or
                                growth) falls out of favor with the stock market
                             -  The Portfolio's investment sector (e.g., small
                                cap, mid cap or foreign securities, which
                                generally are more volatile than U.S. large cap
                                securities) declines or becomes less liquid
                             -  The market undervalues the stocks held for
                                longer than expected, or the stocks purchased
                                turn out not to be undervalued
                             -  The stocks selected for growth potential do not
                                achieve such growth.

                             You could lose money on your investment in the
                             Managed Portfolio (to the extent that the Portfolio
                             invests in debt securities) or the Portfolio may
                             underperform other investments if any of the
                             following happens:

                             -  Interest rates rise and the bond market goes
                                down
                             -  Issuers of debt instruments cannot meet their
                                obligations
                             -  Bond issuers' call bonds selling at a premium to
                                their call price before the maturity date
                             -  Loans securing mortgage-backed obligations
                                prepay principal more rapidly than expected. The
                                Portfolio may have to reinvest these prepayments
                                at lower rates.

BAR CHART &
PERFORMANCE
TABLE
                 The bar chart provides some indication of the risks of
                 investing in the Portfolio by showing changes in the
                 performance of the Portfolio's shares from year to year for the
                 life of the Portfolio and the highest and lowest quarterly
                 return during the life of the Portfolio.

                 The Managed Portfolio's past performance does not necessarily
                 indicate how the Portfolio will perform in the future. The
                 Portfolio's performance does not reflect charges and deductions
                 which are imposed under the variable contracts.

were $682,601,380, with respect to the Old Trust and $51,345,102, with respect
to the Fund. For the period prior to September 16, 1994, the performance figures
above for the Managed Portfolio reflects the performance of the corresponding
Portfolio of the Old Trust. The Old Trust commenced operations on August 1,
1988.

                         PRINCIPAL INVESTMENT STRATEGIES

MANAGED PORTFOLIO

Q  What is the Portfolio's investment objective?

A  Growth of capital over time through investment in a portfolio consisting of
   common stocks, bonds and cash equivalents, the percentages of which will vary
   based on OpCap Advisors' and PIMCO's assessments of the relative outlook for
   such investments.

Q  What is the Portfolio's investment program?

A  The Portfolio seeks to meet its objective by investing in common stocks,
   bonds and cash equivalents in varying percentages based on OpCap Advisors'
   and PIMCO's view of relative values. The Portfolio may purchase securities
   listed on U.S. or foreign securities exchanges or traded in the U.S. or
   foreign over the counter markets. The Portfolio also may purchase investment
   grade U.S. government and corporate bonds and high quality money market
   securities. The Portfolio can invest up to 100% of its assets in debt
   securities but will only do so if equity securities are not an attractive
   investment.

Q  What are the potential rewards of investing in the Portfolio?

A  The Portfolio normally invests mainly in equity securities. Common stocks
   offer a way to invest for long term growth of capital.


                                      RISKS

Q  What are the risks of investing in the Portfolio?

A  The Managed Portfolio invests principally in equity securities which may be
   affected by the following:

   STOCK MARKET VOLATILITY - The stock market in general may fluctuate in
   response to political, market and economic developments and you can lose
   money on your investments.

   Equity investors should have a long-term investment horizon and should be
   prepared for the ups and downs of the stock market.

   STOCK PICKING - The portfolio manager may select stocks that have prices that
   turn out not to be undervalued or do not achieve expectations for growth in
   income or revenues.

   ISSUER CHANGES - Changes in the financial condition of an issuer or changes
   in economic conditions that affect a particular type of issuer can affect the
   value or credit quality of an issuer's securities.


                                       7
<PAGE>

   SMALL CAP AND MID CAP VOLATILITY - Mid cap stocks are more volatile and have
   less trading volume than large cap stocks. Small cap stocks are more volatile
   and have less trading volume than both large cap and mid cap stocks.

   SECTOR RISK - OpCap Advisors are bottom up investment managers. That means
   that they select securities for a Portfolio based on the investment merits of
   a particular issue rather than the business sector.

   INVESTMENT STYLES - Value or growth stocks may be out of favor for a period
   of time. Both investment styles can produce poor returns for a period of
   time.

   ASSET ALLOCATION RISK - The Managed Portfolio invests in a mix of equity and
   fixed income securities. The portfolio manager of the Managed Portfolio can
   make the wrong allocation decisions.

   FOREIGN EXPOSURE - When selecting foreign securities for the Portfolio, OpCap
   Advisors use approximately the same standards that they set for U.S. issuers.
   Foreign securities, foreign currencies and securities issued by U.S. entities
   with substantial foreign operations may have additional risks than U.S.
   securities.

     -   Political Risk - Foreign governments can take over the assets or
         operations of a company or may impose taxes or limits on the removal
         of the Portfolio's assets from that country.

     -   Currency risk - The value of securities held in foreign currencies will
         be affected by changes in the value of that currency.

     -   Liquidity - Some foreign markets are less liquid and more volatile than
         the U.S. stock market.

     -   Limited information - There may be less public information about
         foreign issuers than there is about U.S. issuers.

     -   Settlement and clearance - Some foreign markets experience delays in
         settlement. These delays could cause the Portfolio to miss investment
         opportunities or to be unable to sell a security.

     -   Euro - The effect of the Euro on international markets has not yet been
         determined.

     -   Emerging Markets - There are greater risks of unstable governments and
         economies and restriction on foreign ownership in these countries. The
         Portfolio presently intends to limit investment in emerging markets to
         no more than 5% of its total assets.

To the extent that the Managed Portfolio invests in debt securities, the
Portfolio is exposed to these risks:


                                       8
<PAGE>

     -   Interest rate risk - The risk that changes in interest rates will
         affect the value of fixed income securities in the Portfolio.

     -   Prepayment risk - The risk that the holder of a mortgage underlying a
         mortgage backed security will prepay principal.

     -   Credit risk - The risk that an issuer of a fixed income security will
         be unable to pay principal and interest payments when they are due.



                               INVESTMENT POLICIES

Q  Can a Portfolio change its investment objective and investment policies?

A  Fundamental policies of a Portfolio cannot be changed without the approval of
   a majority of the outstanding voting shares of the Portfolio. A Portfolio's
   investment objective is a fundamental policy. Investment restrictions that
   are fundamental policies are listed in the Statement of Additional
   Information. Investment policies are not fundamental and can be changed by
   the Fund's Board of Trustees.

Q  Can the Portfolio use derivative instruments?

A  Yes. The Managed Portfolio may use the following derivative instruments:

   -  futures contracts
   -  options on futures contracts
   -  forward foreign currency contracts
   -  covered calls written on individual securities
   -  uncovered calls and puts
   -  options on stock indices.

   The Managed Portfolio will sometimes use derivative instruments as part of a
   strategy designed to reduce exposure to other risks, such as interest risk or
   currency risk, and may use derivative instruments to meet their investment
   objectives.

Q  What are the risks of derivative instruments?

A  Derivative instruments can reduce the return of a Portfolio if :

   -  Its investment adviser uses a derivative instrument at the wrong time
   -  The prices of a Portfolio's futures or options positions are not
      correlated with its other investments
   -  A Portfolio cannot close out a position because of an illiquid market.


                                       9
<PAGE>

Q  Does the Portfolio expect to engage in short-term trading?

A  The Portfolio does not expect to engage in frequent short-term trading. The
   Financial Highlights table in this prospectus shows the Portfolio's turnover
   rates during prior fiscal years.

Q  Can the Portfolio vary from its investment goals?

A  When a Portfolio's investment adviser or subadviser thinks market or economic
   conditions are adverse, it may invest up to 100% of its assets in defensive
   investments such as U.S. Government securities and money market instruments.
   To the extent that a Portfolio takes a defensive position, it will not be
   pursuing its investment objective.


                                 FUND MANAGEMENT

OPCAP ADVISORS

The Board of Trustees of the Fund has hired OpCap Advisors to serve as manager
of the Fund.

OpCap Advisors is a subsidiary of Oppenheimer Capital, an investment advisory
firm with approximately $53 billion of assets under management as of
December 31, 1999. They are indirect wholly-owned subsidiaries of PIMCO Advisors
L.P. The mailing address is 1345 Avenue of the Americas, New York, New
York 10105.

The general partners of PIMCO Advisors L.P. are PIMCO Partners G.P. and PIMCO
Advisors Holding L.P. ("PAH"). PIMCO Partners, G.P. is a general partnership
between PIMCO Holdings LLC, a Delaware limited liability company and an indirect
wholly-owned subsidiary of Pacific Life Insurance Company, and PIMCO Partners
LLC, a California limited liability company controlled by the current Managing
Directors and two former Managing Directors of Pacific Investment Management
Company, a subsidiary of PIMCO Advisors L.P. PIMCO Partners, G.P. is the sole
general partner of PAH.

On October 31, 1999, PIMCO Advisors L.P., PAH and Allianz AG ("Allianz")
announced that they had reached a definitive agreement pursuant to which Allianz
will acquire majority ownership of PIMCO Advisors L.P. and its subsidiaries,
including OpCap Advisors (the "Allianz Transaction"). Under the terms of the
transaction, Allianz will acquire all of PAH, the publicly traded general
partner of PIMCO Advisors L.P. Pacific Life Insurance Company will retain an
approximately 30% interest in PIMCO Advisors L.P. The Allianz Transaction is
currently expected to be completed by on or about May 5, 2000.

Allianz is the world's second largest insurance company and a leading provider
of financial services, particularly in Europe, and is represented in 68
countries world-wide through subsidiaries, branch and representative offices,
and other affiliated entities. Allianz currently has assets under management of
more than $390 billion, and in its last fiscal year wrote approximately $50
billion in gross insurance premiums. After consummation of the transaction,


                                       10
<PAGE>

the combined firms will have over $650 billion in assets under management.

Affiliates of Allianz currently include Dresdner Bank AG, Deutsche Bank AG,
Munich Re, and Hypo Vereinsbank. These entities, as well as certain broker-
dealers controlled by or affiliated with these entities, such as Bankers Trust
Company and BT Alex Brown, Inc. are considered the "Affiliated Brokers." Once
the Allianz transaction is consummated, absent an SEC exemption or other relief,
the Fund's Portfolios would generally be precluded from effecting principal
transactions with the Affiliated Brokers, and each Portfolio's ability to
purchase securities being underwritten by an Affiliated Broker or to utilize the
Affiliated Brokers for agency transactions would be subject to restrictions.
OpCap Advisors does not believe that the restrictions on transactions with the
Affiliated Brokers described above will materially adversely affect its ability,
post-closing, to provide services to the Fund, the ability of the Portfolios to
take advantage of market opportunities, or the overall performance of the
Portfolios.

The consummation of the Allianz Transaction is subject to the approval of the
public unitholders of PAH, as well as to certain regulatory and client
approvals, and other conditions customary to transactions of this kind.

This Prospectus will be supplemented or revised if the Allianz Transaction does
not occur substantially as set forth above.

OpCap Advisors has been in business as an investment adviser since 1987 and
Oppenheimer Capital has been in business as an investment adviser since 1969.

OpCap Advisors manages the investments of the Portfolio (and places brokerage
orders) and conducts the business affairs of the Fund. Employees of Oppenheimer
Capital, PIMCO Advisors and OpCap Advisors perform these services.

The Managed Portfolio paid OpCap Advisors fees in return for providing or
arranging for the provision of investment advisory services. OpCap also pays a
portion of its advisory fees to PIMCO in return for the advisory services PIMCO
performs for the Managed Portfolio. The Managed Portfolio of the Fund listed
below paid OpCap Advisors the following fees as a percentage of average daily
net assets during the fiscal year ended December 31, 1999:

<TABLE>
           <S>                                                    <C>
           Managed Portfolio......................................0.77%
</TABLE>

OpCap will pay PIMCO a fee at the annual rate of 0.25% of the average daily net
assets of the Managed Portfolio for the advisory services PIMCO performed for
the Managed Portfolio.

The Fund pays OpCap Advisors at the annual rate of .80% of the first $400
million of average net assets, .75% on the next $400 million of average net
assets and .70% of assets in excess of $800 million with respect to the Managed
Portfolio.

                                   SHARE PRICE

The Fund calculates the Portfolio's share price, called its net asset value, on
each business day that the New York Stock Exchange is open after the close of
regular trading (generally 4:00 p.m. Eastern Standard Time). Net asset value per
share is computed by adding up the total value of a Portfolio's investments and
other assets, subtracting its liabilities and then dividing by the number of
shares outstanding.

                               TOTAL PORTFOLIO ASSETS - LIABILITIES
         Net Asset Value =   -------------------------------------------
                               NUMBER OF PORTFOLIO SHARES OUTSTANDING

The Fund uses the market prices of securities to value a Portfolio's investments
unless securities do not have market quotations or are short-term debt
securities. When the Fund uses fair value to price a security, the Fund reviews
the pricing method with the Fund's Board. The Fund prices short-term investments
that mature in less than 60 days using amortized cost or amortized value.
Foreign securities trade on days when the Portfolios do not price their shares
so the net asset value of a Portfolio's shares may change on days when
shareholders will not be able to buy or sell shares of the Portfolio. If an
event occurs after the close of the New York Stock Exchange that the Fund
believes changes the value of a security, then the Fund will value the security
at what it believes to be fair value.


                             DISTRIBUTIONS AND TAXES

This discussion is about distributions to the Portfolio's shareholders, which
are variable accounts of insurance companies and qualified pension and
retirement plans. You should read the prospectus for the variable account for
information about distributions and federal tax treatment for contract owners of
variable products.

The Portfolio pays dividends from its net investment income and distributes any
net capital gains that it has realized at least once a year.


                              FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the
Portfolio's financial performance. Certain information reflects financial
results for a single Portfolio share. The total returns in the table represent
the rate that an investor would have earned (or lost) on an investment in a
Portfolio (assuming reinvestment of all dividends and distributions). The
information in the financial highlights table below has been audited by
PricewaterhouseCoopers LLP, independent accountants, whose report, along with
the Portfolio's financial statements, is incorporated by reference in the Fund's
SAI, which is available upon request.

PRINCIPAL INVESTMENT
STRATEGIES                          -   The Equity Portfolio invests primarily
                                        in equity securities listed on the New
                                        York Stock Exchange.

                                    -   The Small Cap Portfolio invests
                                        primarily in equity securities of
                                        companies with market capitalizations
                                        under $1 billion.


INVESTMENT
PHILOSOPHY                          OpCap Advisors is the investment adviser to
                                    all of the Portfolios.

                                    For the equity investments it manages
                                    directly, i.e., the Equity, and Small Cap
                                    Portfolios, OpCap Advisors applies
                                    principles of value investing, although the
                                    individual portfolio managers may implement
                                    those principles differently.

                                    When selecting equity securities, OpCap
                                    Advisors believes there are two major
                                    components of value.

                                    -   A company's ability to generate earnings
                                        that contribute to shareholder value.
                                        OpCap Advisors considers discretionary
                                        cash flow-cash that remains after a
                                        company spends what is needed to sustain
                                        its industrial position as a primary
                                        determinant of a company's potential to
                                        add economic value.

                                    -   Price - OpCap Advisors looks for market
                                        undervaluation great enough to offer the
                                        potential for upside reward with what it
                                        believes is modest downward risk.

                                    OpCap Advisors uses fundamental company
                                    analysis to select securities. Fundamental
                                    company analysis involves intensive
                                    evaluation of historic financial data
                                    including:

                                   - Company financial statements
                                   - Market share analysis
                                   - Unit volume growth
                                   - Barriers to entry
                                   - Pricing policies
                                   - Management record.

                                    OpCap Advisors uses fundamental company
                                    analysis to select companies they believe
                                    have one or more of the following
                                    characteristics:

                                    - substantial and growing discretionary cash
                                      flow
                                    - strong shareholder value-oriented
                                      management
                                    - valuable consumer or commercial
                                      franchises
                                    - high returns on capital
                                    - favorable price to intrinsic value
                                      relationship.

                                    In selecting debt securities, OpCap Advisors
                                    analyzes yield relationships between
                                    different sectors and among securities along
                                    the yield curve. OpCap Advisors seeks to
                                    take advantage of maturities and individual
                                    issues that are inexpensive and have the
                                    potential to provide superior returns. In
                                    evaluating high yield debt securities, OpCap
                                    Advisors supplements its traditional credit
                                    analysis with an evaluation of an issuer's
                                    asset values.

                                    There can be no assurance that OpCap
                                    Advisors will achieve its goals.


PRINCIPAL                           RISKS If you invest in the Portfolios that
                                    invest in equity securities, you could lose
                                    money or those Portfolios could underperform
                                    other investments if any of the following
                                    happens:

                                    -  The stock market goes down
                                    -  The Portfolio's investment style (i.e.,
                                       value or growth) falls out of favor with
                                       the stock market
                                    -  The Portfolio's investment sector (e.g.,
                                       small cap, mid cap or foreign securities,
                                       which generally are more volatile than
                                       U.S. large cap securities) declines or
                                       becomes less liquid
                                    -  For the Equity and Small Cap Portfolios,
                                       the market undervalues the stocks held
                                       for longer than expected, or the stocks
                                       purchased turn out not to be undervalued
                                    -  The stocks selected for growth potential
                                       do not achieve such growth.

                                    If you invest in the Portfolios that invest
                                    in debt securities, you could lose money or
                                    your investment may underperform other
                                    investments if any of the following happens:

                                    - Interest rates rise and the bond market
                                      goes down
                                    - Issuers of debt instruments cannot meet
                                      their obligations
                                    - Bond issuers' call bonds selling at a
                                      premium to their call price

                                      before the maturity date
                                    - Loans securing mortgage-backed obligations
                                      prepay principal more rapidly than
                                      expected. The Portfolios may have to
                                      reinvest these prepayments at lower
                                      rates.

BAR CHART &
PERFORMANCE
TABLE
                     The bar charts provide some indication of the risks of
                     investing in the Portfolios by showing changes in the
                     performance of each Portfolio's shares from year to year
                     for the life of each Portfolio and the highest and lowest
                     quarterly return during the life of each Portfolio.

                     The Portfolios' past performance does not necessarily
                     indicate how each Portfolio will perform in the future. The
                     Portfolios' performance does not reflect charges and
                     deductions which are imposed under the variable contracts.

                         PRINCIPAL INVESTMENT STRATEGIES

EQUITY PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Long term capital appreciation through investment in a diversified
     portfolio of equity securities selected on the basis of a value approach to
     investing.

Q    What is the Portfolio's investment program?

A    The Equity Portfolio invests primarily in equity securities of companies
     that OpCap Advisors believes are undervalued in the marketplace. Under
     normal conditions, the Portfolio will invest at least 65% of its total
     assets in equity securities listed on the New York Stock Exchange. The
     Portfolio also may purchase securities listed on other U.S. or foreign
     securities exchanges or traded in the U.S. or foreign over the counter
     markets.

     The Equity Portfolio is managed to follow a composite portfolio constructed
     by a group of senior portfolio managers at OpCap Advisors.

Q    What are the potential rewards of investing in the Portfolio?

A    Common stocks and other equity securities offer a way to invest for long
     term growth of capital. Equity investors should have a long term investment
     horizon and should be prepared for the ups and downs of the stock markets.


SMALL CAP PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Capital appreciation through a diversified portfolio consisting primarily
     of securities of companies with market capitalizations of under $1 billion
     at time of purchase.

Q    What is the Portfolio's investment program?

A    The Portfolio invests primarily in equity securities of companies with
     market capitalizations under $1 billion at the time of purchase that OpCap
     Advisors believes are undervalued in the


                                       7
<PAGE>

     marketplace. The Portfolio may purchase securities listed on U.S. or
     foreign securities exchanges or traded in the U.S. or foreign over the
     counter markets. The Portfolio also may purchase securities in initial
     public offerings or shortly after those offerings have been completed.

Q    What are the potential rewards of investing in the Portfolio?

A    Common stocks offer a way to invest for long term growth of capital.
     Opportunities for value creation for small cap companies could result from
     product expansion or product improvement, industry transition, new
     management or sale of the company. Small cap companies are followed by
     fewer analysts than are large and mid cap companies. So as additional
     analysts follow a small cap stock, investor demand for the stock may
     increase.


                                      RISKS

Q    What are the risks of investing in the Portfolios?

A    The Equity and Small Cap Portfolios invest principally in equity securities
     which may be affected by the following:

     STOCK MARKET VOLATILITY - The stock market in general may fluctuate in
     response to political, market and economic developments and you can lose
     money on your investments.

     Equity investors should have a long-term investment horizon and should be
     prepared for the ups and downs of the stock market.

     STOCK PICKING - The portfolio manager may select stocks that have prices
     that turn out not to be undervalued or do not achieve expectations for
     growth in income or revenues.

     ISSUER CHANGES - Changes in the financial condition of an issuer or changes
     in economic conditions that affect a particular type of issuer can affect
     the value or credit quality of an issuer's securities.

     SMALL CAP AND MID CAP VOLATILITY - Mid cap stocks are more volatile and
     have less trading volume than large cap stocks. Small cap stocks are more
     volatile and have less trading volume than both large cap and mid cap
     stocks.

     SECTOR RISK - OpCap Advisors are bottom up investment managers. That means
     that they select securities for a Portfolio based on the investment merits
     of a particular issue rather than the business sector.

     INVESTMENT STYLES - Value or growth stocks may be out of favor for a period
     of time. Both investment styles can produce poor returns for a period of
     time.


                                       8
<PAGE>

     FOREIGN EXPOSURE - When selecting foreign securities for the Portfolio,
     OpCap Advisors use approximately the same standards that they set for U.S.
     issuers. Foreign securities, foreign currencies and securities issued by
     U.S. entities with substantial foreign operations may have additional risks
     than U.S. securities.

         -    Political Risk - Foreign governments can take over the assets or
              operations of a company or may impose taxes or limits on the
              removal of the Portfolio's assets from that country.

         -    Currency risk - The value of securities held in foreign currencies
              will be affected by changes in the value of that currency.

         -    Liquidity - Some foreign markets are less liquid and more
              volatile than the U.S. stock market.

         -    Limited information - There may be less public information about
              foreign issuers than there is about U.S. issuers.

         -    Settlement and clearance - Some foreign markets experience delays
              in settlement. These delays could cause the Portfolio to miss
              investment opportunities or to be unable to sell a security.

         -    Euro - The effect of the Euro on international markets has not yet
              been determined.

         -    Emerging Markets - There are greater risks of unstable governments
              and economies and restriction on foreign ownership in these
              countries. The Portfolios presently intend to limit investment in
              emerging markets to no more than 5% of their total assets.

To the extent that the Portfolios invest in debt securities, the Portfolios are
exposed to these risks:

         -    Interest rate risk - The risk that changes in interest rates will
              affect the value of fixed income securities in the Portfolio.

         -    Prepayment risk - The risk that the holder of a mortgage
              underlying a mortgage backed security will prepay principal.

         -    Credit risk - The risk that an issuer of a fixed income security
              will be unable to pay principal and interest payments when they
              are due.

                               INVESTMENT POLICIES

Q    Can a Portfolio change its investment objective and investment policies?

A    Fundamental policies of a Portfolio cannot be changed without the approval
     of a majority of the outstanding voting shares of the Portfolio. A
     Portfolio's investment objective is a fundamental policy. Investment
     restrictions that are fundamental policies are listed in the Statement of
     Additional Information. Investment policies are not fundamental and can be
     changed by the Fund's Board of Trustees.

Q    Can the Portfolios use derivative instruments?

A    Yes. The Equity and Small Cap Portfolios may use the following derivative
     instruments:

     -   futures contracts
     -   options on futures contracts
     -   forward foreign currency contracts
     -   covered calls written on individual securities
     -   uncovered calls and puts
     -   options on stock indices.

     The Equity and Small Cap Portfolios do not expect to use derivative
instruments significantly, if at all.

Q    What are the risks of derivative instruments?

A    Derivative instruments can reduce the return of a Portfolio if :

     -   Its investment adviser uses a derivative instrument at the wrong time
     -   The prices of a Portfolio's futures or options positions are not
         correlated with its other investments
     -   A Portfolio cannot close out a position because of an illiquid market.

Q    Do the Portfolios expect to engage in short-term trading?

A    The Portfolios do not expect to engage in frequent short-term trading. The
     Financial Highlights table in this prospectus shows the turnover rates
     during prior fiscal years for the Portfolios that were active during this
     period.

Q    Can the Portfolios vary from their investment goals?

A    When a Portfolio's investment adviser or subadviser thinks market or
     economic conditions are adverse, it may invest up to 100% of its assets in
     defensive investments such as U.S. Government securities and money market
     instruments. To the extent that a Portfolio takes a defensive position, it
     will not be pursuing its investment objective.

                                 FUND MANAGEMENT

OPCAP ADVISORS

The Board of Trustees of the Fund has hired OpCap Advisors to serve as manager
of the Fund.

OpCap Advisors is a subsidiary of Oppenheimer Capital, an investment advisory
firm with approximately $53 billion of assets under management as of December
31, 1999. They are indirect wholly-owned subsidiaries of PIMCO Advisors L.P. The
mailing address is 1345 Avenue of the Americas, New York, New York 10105.

The general partners of PIMCO Advisors L.P. are PIMCO Partners G.P. and PIMCO
Advisors Holding L.P. ("PAH"). PIMCO Partners, G.P. is a general partnership
between PIMCO Holdings LLC, a Delaware limited liability company and an indirect
wholly-owned subsidiary of Pacific Life Insurance Company, and PIMCO Partners
LLC, a California limited liability company controlled by the current Managing
Directors and two former Managing Directors of Pacific Investment Management
Company, a subsidiary of PIMCO Advisors L.P. PIMCO Partners, G.P. is the sole
general partner of PAH.

On October 31, 1999, PIMCO Advisors L.P., PAH and Allianz AG ("Allianz")
announced that they had reached a definitive agreement pursuant to which Allianz
will acquire majority ownership of PIMCO Advisors L.P. and its subsidiaries,
including OpCap Advisors (the "Allianz Transaction"). Under the terms of the
transaction, Allianz will acquire all of PAH, the publicly traded general
partner of PIMCO Advisors L.P. Pacific Life Insurance Company will retain an
approximately 30% interest in PIMCO Advisors L.P. The Allianz Transaction is
currently expected to be completed by on or about May 5, 2000.

Allianz is the world's second largest insurance company and a leading provider
of financial services, particularly in Europe, and is represented in 68
countries world-wide through subsidiaries, branch and representative offices,
and other affiliated entities. Allianz currently has assets under management of
more than $390 billion, and in its last fiscal year wrote approximately $50
billion in gross insurance premiums. After consummation of the transaction, the
combined firms will have over $650 billion in assets under management.

Affiliates of Allianz currently include Dresdner Bank AG, Deutsche Bank AG,
Munich Re, and Hypo Vereinsbank. These entities, as well as certain broker-
dealers controlled by or affiliated with these entities, such as Bankers Trust
Company and BT Alex Brown, Inc. are considered the "Affiliated Brokers." Once
the Allianz transaction is consummated, absent an SEC exemption or other relief,
the Fund's Portfolios would generally be precluded from effecting principal
transactions with the Affiliated Brokers, and each Portfolio's ability to
purchase securities being underwritten by an Affiliated Broker or to utilize the
Affiliated Brokers for agency transactions would be subject to restrictions.
OpCap Advisors does not believe that the restrictions on transactions with the
Affiliated Brokers described above will materially adversely affect its ability,
post-closing, to provide services to the Fund, the ability of the Portfolios to
take advantage of market opportunities, or the overall performance of the
Portfolios.


                                       11
<PAGE>

The consummation of the Allianz Transaction is subject to the approval of the
public unitholders of PAH, as well as to certain regulatory and client
approvals, and other conditions customary to transactions of this kind.

This Prospectus will be supplemented or revised if the Allianz Transaction does
not occur substantially as set forth above.

OpCap Advisors has been in business as an investment adviser since 1987 and
Oppenheimer Capital has been in business as an investment adviser since 1969.

OpCap Advisors manages the investments of certain Portfolios (and places
brokerage orders) and conducts the business affairs of the Fund. Employees of
Oppenheimer Capital, PIMCO Advisors and OpCap Advisors perform these services.

Each Portfolio pays OpCap Advisors fees in return for providing or arranging for
the provision of investment advisory services. The Portfolios of the Fund listed
below paid OpCap Advisors the following fees as a percentage of average daily
net assets during the fiscal year ended December 31, 1999:

<TABLE>
                <S>                                             <C>
                Equity Portfolio................................0.80%
                Small Cap Portfolio.............................0.80%
</TABLE>

The Fund pays OpCap Advisors at the annual rate of .80% of the first $400
million of average net assets, .75% on the next $400 million of average net
assets and .70% of assets in excess of $800 million with respect to the Equity
and Small Cap Portfolios.

                                          including research, analysis and
                                          investment management. He acts as a

                                          capitalization funds. Prior to joining
                                          Oppenheimer Capital, he was Director
                                          of Research and Associate Portfolio
                                          Manager at Palisade Capital

                                          Corp. for over three years. He has a
                                          BS degree in marketing from the
                                          University of Scranton.

                                   SHARE PRICE

The Fund calculates each Portfolio's share price, called its net asset value, on
each business day that the New York Stock Exchange is open after the close of
regular trading (generally 4:00 p.m. Eastern Standard Time). Net asset value per
share is computed by adding up the total value of a Portfolio's investments and
other assets, subtracting its liabilities and then dividing by the number of
shares outstanding.

                              TOTAL PORTFOLIO ASSETS - LIABILITIES
         Net Asset Value =  -----------------------------------------
                              NUMBER OF PORTFOLIO SHARES OUTSTANDING

The Fund uses the market prices of securities to value a Portfolio's investments
unless securities do not have market quotations or are short-term debt
securities. When the Fund uses fair value to price a security, the Fund reviews
the pricing method with the Fund's Board. The Fund prices short-term investments
that mature in less than 60 days using amortized cost or amortized value.
Foreign securities trade on days when the Portfolios do not price their shares
so the net asset value of a Portfolio's shares may change on days when
shareholders will not be able to buy or sell shares of the Portfolio. If an
event occurs after the close of the New York Stock Exchange that the Fund
believes changes the value of a security, then the Fund will value the security
at what it believes to be fair value.


                             DISTRIBUTIONS AND TAXES

This discussion is about distributions to the Portfolio's shareholders, which
are variable accounts of insurance companies and qualified pension and
retirement plans. You should read the prospectus for the variable account for
information about distributions and federal tax treatment for contract owners of
variable products.

Each Portfolio pays dividends from its net investment income and distributes any
net capital gains that it has realized at least once a year.

                              FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the
Portfolio's financial performance. Certain information reflects financial
results for a single Portfolio share. The total returns in the table represent
the rate that an investor would have earned (or lost) on an investment in a
Portfolio (assuming reinvestment of all dividends and distributions). The
information in the financial highlights table below has been audited by
PricewaterhouseCoopers LLP, independent accountants, whose report, along with
the Portfolio's financial statements, is incorporated by reference in the Fund's
SAI, which is available upon request.

INVESTMENT
PHILOSOPHY                  OpCap Advisors is the investment adviser to all of
                            the Portfolios. OpCap Advisors has retained Pacific
                            Investment Management Company ("PIMCO") as
                            sub-adviser for a portion of the assets of the
                            Managed Portfolio.

                            For the equity investments it manages directly,
                            i.e., the Equity, Small Cap and Global Equity
                            Portfolios and the portion of the assets of the
                            Managed Portfolios not sub-advised by its
                            affiliates, OpCap Advisors applies principles of
                            value investing, although the individual portfolio
                            managers may implement those principles differently.

                            When selecting equity securities, OpCap Advisors
                            believes there are two major components of value.

                            -  A company's ability to generate earnings that
                               contribute to shareholder value. OpCap Advisors

                               determinant of a company's potential to add

                               is modest downward risk.

                            OpCap Advisors uses fundamental company analysis to
                            select securities. Fundamental company analysis
                            involves intensive evaluation of historic financial
                            data including:

                            -  Company financial statements
                            -  Market share analysis
                            -  Unit volume growth
                            -  Barriers to entry
                            -  Pricing policies
                            -  Management record.

                            OpCap Advisors uses fundamental company analysis to
                            select companies they believe have one or more of
                            the following characteristics:

                            -  substantial and growing discretionary cash flow
                            -  strong shareholder value-oriented management
                            -  valuable consumer or commercial franchises
                            -  high returns on capital
                            -  favorable price to intrinsic value relationship.

                            In selecting debt securities, OpCap Advisors
                            analyzes yield relationships between different
                            sectors and among securities along the yield curve.
                            OpCap Advisors seeks to take advantage of maturities
                            and individual issues that are inexpensive and have
                            the potential to provide superior returns. In
                            evaluating high yield debt securities, OpCap
                            Advisors supplements its traditional credit analysis
                            with an evaluation of an issuer's asset values.

                            There can be no assurance that OpCap Advisors will
                            achieve its goals.

                            PIMCO acts as the sub-adviser to the Managed

                            selecting securities for the Managed Portfolio,
                            PIMCO develops an outlook for interest rates,
                            currency exchange rates and the economy; analyzes
                            credit and call risks, and uses other security
                            selection techniques. The proportion of the
                            Portfolio's assets committed to investment in
                            securities with particular characteristics (such as
                            quality, section interest rate or maturity) varies
                            based on PIMCO's outlook for the U.S. economy and
                            the economies of other countries in the world, the
                            financial markets and other factors.

                            PIMCO attempts to identify areas of the bond market
                            that are undervalued relative to the rest of the
                            market. PIMCO identifies these areas by grouping
                            bonds into the following sectors: money markets,
                            governments, corporates, mortgages, asset-backed and
                            international. Sophisticated proprietary software
                            then assists in evaluating sectors and pricing
                            specific securities. Once investment opportunities
                            are identified, PIMCO will shift assets among
                            sectors depending upon changes in relative
                            valuations and credit spreads. There is no guarantee
                            that PIMCO's security selection techniques will
                            produce the desired results.

PRINCIPAL RISKS             If you invest in the Portfolios that invest in
                            equity securities, you could lose money or those
                            Portfolios could underperform other investments if
                            any of the following happens:

                            -  The stock market goes down
                            -  The Portfolio's investment style (i.e., value or
                               growth) falls out of favor with the stock market
                            -  The Portfolio's investment sector (e.g., small
                               cap, mid cap or foreign securities, which
                               generally are more volatile than U.S. large cap
                               securities) declines or becomes less liquid
                            -  For the Equity, Small Cap, Global Equity and
                               Managed Portfolios, the market undervalues the
                               stocks held for longer than expected, or the
                               stocks purchased turn out not to be undervalued
                            -  The stocks selected for growth potential do not
                               achieve such growth.

                            If you invest in the Portfolios that invest in debt
                            securities, you could lose money or your investment
                            may underperform other investments if any of the
                            following happens:

                            -  Interest rates rise and the bond market goes down
                            -  Issuers of debt instruments cannot meet their
                               obligations
                            -  Bond issuers' call bonds selling at a premium to
                               their call price before the maturity date

                            -  Loans securing mortgage-backed obligations prepay
                               principal more rapidly than expected. The
                               Portfolios may have to reinvest these prepayments
                               at lower rates.

                            The U.S. Government Income Portfolio principally
                            buys fixed income securities that are issued or
                            guaranteed by the U.S. Government or its agencies or
                            instrumentalities, so credit risk should below.

BAR CHART &
PERFORMANCE
TABLE
               The bar charts provide some indication of the risks of investing
               in the Portfolios by showing changes in the performance of each
               Portfolio's shares from year to year for the life of each
               Portfolio and the highest and lowest quarterly return during the
               life of each Portfolio.

               The Portfolios' past performance does not necessarily indicate
               how each Portfolio will perform in the future. The Portfolios'
               performance does not reflect charges and deductions which are
               imposed under the variable contracts.

                         PRINCIPAL INVESTMENT STRATEGIES

EQUITY PORTFOLIO

Q  What is the Portfolio's investment objective?

A  Long term capital appreciation through investment in a diversified portfolio
   of equity securities selected on the basis of a value approach to investing.

Q  What is the Portfolio's investment program?

A  The Equity Portfolio invests primarily in equity securities of companies that
   OpCap Advisors believes are undervalued in the marketplace. Under normal
   conditions, the Portfolio will invest at least 65% of its total assets in
   equity securities listed on the New York Stock Exchange. The Portfolio also
   may purchase securities listed on other U.S. or foreign securities exchanges
   or traded in the U.S. or foreign over the counter markets.

   The Equity Portfolio is managed to follow a composite portfolio constructed
   by a group of senior portfolio managers at OpCap Advisors.

Q  What are the potential rewards of investing in the Portfolio?

A  Common stocks and other equity securities offer a way to invest for long term
   growth of capital. Equity investors should have a long term investment
   horizon and should be prepared for the ups and downs of the stock markets.


SMALL CAP PORTFOLIO

Q  What is the Portfolio's investment objective?

A  Capital appreciation through a diversified portfolio consisting primarily of
   securities of companies with market capitalizations of under $1 billion at
   time of purchase.


                                       9
<PAGE>

Q  What is the Portfolio's investment program?

A  The Portfolio invests primarily in equity securities of companies with market
   capitalizations under $1 billion at the time of purchase that OpCap Advisors
   believes are undervalued in the marketplace. The Portfolio may purchase
   securities listed on U.S. or foreign securities exchanges or traded in the
   U.S. or foreign over the counter markets. The Portfolio also may purchase
   securities in initial public offerings or shortly after those offerings have
   been completed.

Q  What are the potential rewards of investing in the Portfolio?

A  Common stocks offer a way to invest for long term growth of capital.
   Opportunities for value creation for small cap companies could result from
   product expansion or product improvement, industry transition, new management
   or sale of the company. Small cap companies are followed by fewer analysts
   than are large and mid cap companies. So as additional analysts follow a
   small cap stock, investor demand for the stock may increase.


GLOBAL EQUITY PORTFOLIO

Q  What is the Portfolio's investment objective?

A  Long term capital appreciation through pursuit of a global investment
   strategy primarily involving equity securities.

Q  What is the Portfolio's investment program?

A  The Portfolio invests primarily in equity securities of companies located
   throughout the world which OpCap Advisors believes are undervalued in the
   marketplace. The Portfolio may invest up to 35% of its total assets in fixed
   income securities which may be lower than investment grade.

Q  What are the potential rewards of investing in the Portfolio?

A  Foreign securities provide additional opportunities and diversification. U.S.
   stocks represent less than half of the world's stock market capitalization.


MANAGED PORTFOLIO

Q  What is the Portfolio's investment objective?

A  Growth of capital over time through investment in a portfolio consisting of
   common stocks, bonds and cash equivalents, the percentages of which will vary
   based on OpCap Advisors' and PIMCO's assessments of the relative outlook for
   such investments.


                                       10
<PAGE>

Q  What is the Portfolio's investment program?

A  The Portfolio seeks to meet its objective by investing in common stocks,
   bonds and cash equivalents in varying percentages based on OpCap Advisors'
   and PIMCO's view of relative values. The Portfolio may purchase securities
   listed on U.S. or foreign securities exchanges or traded in the U.S. or
   foreign over the counter markets. The Portfolio also may purchase investment
   grade U.S. government and corporate bonds and high quality money market
   securities. The Portfolio can invest up to 100% of its assets in debt
   securities but will only do so if equity securities are not an attractive
   investment.

Q  What are the potential rewards of investing in the Portfolio?

A  The Portfolio normally invests mainly in equity securities. Common stocks
   offer a way to invest for long term growth of capital.

U.S. GOVERNMENT INCOME PORTFOLIO

Q  What is the Portfolio's investment objective?

A  High level of current income together with protection of capital by investing
   exclusively in debt obligations, including mortgage-backed securities issued
   or guaranteed by the United States government, its agencies or
   instrumentalities.

Q  What is the Portfolio's investment program?

A  The Portfolio invests in debt obligations issued or guaranteed by the United
   States Government, its agencies or instrumentalities. These securities are
   referred to as "U.S. Government Securities." The Portfolio also may purchase
   mortgage-backed securities to effectuate this program.

   OpCap Advisors observes current and historical yield relationships between
   maturities and sectors to seek the best relative values. The Portfolio
   generally maintains an average maturity between five and ten years. OpCap
   Advisors does not attempt to forecast interest rates in managing the
   Portfolio.

Q  What are the potential rewards of investing in the Portfolio?

A  The Portfolio consists of the highest quality debt instruments. Since the
   average maturity of the Portfolio's investments are between five and ten
   years, the Portfolio should be less volatile than a longer term bond fund.


                                      RISKS

Q  What are the risks of investing in the Portfolios?


                                       11
<PAGE>

A  The Equity, Small Cap, Global Equity and Managed Portfolios invest
   principally in equity securities which may be affected by the following:

   STOCK MARKET VOLATILITY - The stock market in general may fluctuate in
   response to political, market and economic developments and you can lose
   money on your investments.

   Equity investors should have a long-term investment horizon and should be
   prepared for the ups and downs of the stock market.

   STOCK PICKING - The portfolio manager may select stocks that have prices that
   turn out not to be undervalued or do not achieve expectations for growth in
   income or revenues.

   ISSUER CHANGES - Changes in the financial condition of an issuer or changes
   in economic conditions that affect a particular type of issuer can affect the
   value or credit quality of an issuer's securities.

   SMALL CAP AND MID CAP VOLATILITY - Mid cap stocks are more volatile and have
   less trading volume than large cap stocks. Small cap stocks are more volatile
   and have less trading volume than both large cap and mid cap stocks.

   SECTOR RISK - OpCap Advisors are bottom up investment managers. That means
   that they select securities for a Portfolio based on the investment merits of
   a particular issue rather than the business sector.

   INVESTMENT STYLES - Value or growth stocks may be out of favor for a period
   of time. Both investment styles can produce poor returns for a period of
   time.

   ASSET ALLOCATION RISK - The Managed Portfolio invests in a mix of equity and
   fixed income securities. The portfolio manager of the Managed Portfolio can
   make the wrong allocation decisions.

   FOREIGN EXPOSURE - When selecting foreign securities for the Portfolio, OpCap
   Advisors use approximately the same standards that they set for U.S. issuers.
   Foreign securities, foreign currencies and securities issued by U.S. entities
   with substantial foreign operations may have additional risks than U.S.
   securities. This risk is greater for the Global Equity Portfolio which
   invests on a worldwide basis.

     -  Political Risk - Foreign governments can take over the assets or
        operations of a company or may impose taxes or limits on the removal of
        the Portfolio's assets from that country.

     -  Currency risk - The value of securities held in foreign currencies will
        be affected by changes in the value of that currency.

     -  Liquidity - Some foreign markets are less liquid and more volatile than
        the U.S. stock market.


                                       12
<PAGE>

     -  Limited information - There may be less public information about foreign
        issuers than there is about U.S. issuers.

     -  Settlement and clearance - Some foreign markets experience delays in
        settlement. These delays could cause the Portfolio to miss investment
        opportunities or to be unable to sell a security.

     -  Euro - The effect of the Euro on international markets has not yet been
        determined.

     -  Emerging Markets - There are greater risks of unstable governments and
        economies and restriction on foreign ownership in these countries. The
        Portfolios presently intend to limit investment in emerging markets to
        no more than 5% of their total assets.

To the extent that the Portfolios invest in debt securities, the Portfolios are
exposed to these risks:

     -  Interest rate risk - The risk that changes in interest rates will affect
        the value of fixed income securities in the Portfolio.

     -  Prepayment risk - The risk that the holder of a mortgage underlying a
        mortgage backed security will prepay principal.

     -  Credit risk - The risk that an issuer of a fixed income security will be
        unable to pay principal and interest payments when they are due.

To the extent that the Global Equity Portfolio invests in lower grade debt
securities, you should know that lower grade debt may have the following
additional risks:

     -  more volatility

     -  less liquidity

     -  greater risk of issuer default or insolvency.


                               INVESTMENT POLICIES

Q  Can a Portfolio change its investment objective and investment policies?

A  Fundamental policies of a Portfolio cannot be changed without the approval of
   a majority of the outstanding voting shares of the Portfolio. A Portfolio's
   investment objective is a fundamental policy. Investment restrictions that
   are fundamental policies are listed in the Statement of Additional
   Information. Investment policies are not fundamental and can be changed by
   the Fund's Board of Trustees.


                                       13
<PAGE>

Q  Can the Portfolios use derivative instruments?

A  Yes. The Equity, Small Cap, Global Equity and Managed Portfolios may use the
   following derivative instruments:

     -  futures contracts
     -  options on futures contracts
     -  forward foreign currency contracts
     -  covered calls written on individual securities
     -  uncovered calls and puts
     -  options on stock indices.

   The Equity, Small Cap and Global Equity Portfolios do not expect to use
   derivative instruments significantly, if at all. The Managed Portfolio will
   sometimes use derivative instruments as part of a strategy designed to reduce
   exposure to other risks, such as interest risk or currency risk, and may use
   derivative instruments to meet their investment objectives.

Q  What are the risks of derivative instruments?

A  Derivative instruments can reduce the return of a Portfolio if :

     -  Its investment adviser uses a derivative instrument at the wrong time
     -  The prices of a Portfolio's futures or options positions are not
        correlated with its other investments
     -  A Portfolio cannot close out a position because of an illiquid market.

Q  Do the Portfolios expect to engage in short-term trading?

A  The Portfolios do not expect to engage in frequent short-term trading. The
   Financial Highlights table in this prospectus shows the turnover rates during
   prior fiscal years for the Portfolios that were active during this period.

Q  Can the Portfolios vary from their investment goals?

A  When a Portfolio's investment adviser or subadviser thinks market or economic
   conditions are adverse, it may invest up to 100% of its assets in defensive
   investments such as U.S. Government securities and money market instruments.
   To the extent that a Portfolio takes a defensive position, it will not be
   pursuing its investment objective.


                                 FUND MANAGEMENT

OPCAP ADVISORS

The Board of Trustees of the Fund has hired OpCap Advisors to serve as manager
of the Fund.


                                       14
<PAGE>

OpCap Advisors is a subsidiary of Oppenheimer Capital, an investment advisory
firm with approximately $53 billion of assets under management as of
December 31, 1999. They are indirect wholly-owned subsidiaries of PIMCO Advisors
L.P. The mailing address is 1345 Avenue of the Americas, New York, New
York 10105.

The general partners of PIMCO Advisors L.P. are PIMCO Partners G.P. and PIMCO
Advisors Holding L.P. ("PAH"). PIMCO Partners, G.P. is a general partnership
between PIMCO Holdings LLC, a Delaware limited liability company and an indirect
wholly-owned subsidiary of Pacific Life Insurance Company, and PIMCO Partners
LLC, a California limited liability company controlled by the current Managing
Directors and two former Managing Directors of Pacific Investment Management
Company, a subsidiary of PIMCO Advisors L.P. PIMCO Partners, G.P. is the sole
general partner of PAH.

On October 31, 1999, PIMCO Advisors L.P., PAH and Allianz AG ("Allianz")
announced that they had reached a definitive agreement pursuant to which Allianz
will acquire majority ownership of PIMCO Advisors L.P. and its subsidiaries,
including OpCap Advisors (the "Allianz Transaction"). Under the terms of the
transaction, Allianz will acquire all of PAH, the publicly traded general
partner of PIMCO Advisors L.P. Pacific Life Insurance Company will retain an
approximately 30% interest in PIMCO Advisors L.P. The Allianz Transaction is
currently expected to be completed by on or about May 5, 2000.

Allianz is the world's second largest insurance company and a leading provider
of financial services, particularly in Europe, and is represented in 68
countries world-wide through subsidiaries, branch and representative offices,
and other affiliated entities. Allianz currently has assets under management of
more than $390 billion, and in its last fiscal year wrote approximately $50
billion in gross insurance premiums. After consummation of the transaction, the
combined firms will have over $650 billion in assets under management.

Affiliates of Allianz currently include Dresdner Bank AG, Deutsche Bank AG,
Munich Re, and Hypo Vereinsbank. These entities, as well as certain broker-
dealers controlled by or affiliated with these entities, such as Bankers Trust
Company and BT Alex Brown, Inc. are considered the "Affiliated Brokers." Once
the Allianz transaction is consummated, absent an SEC exemption or other relief,
the Fund's Portfolios would generally be precluded from effecting principal
transactions with the Affiliated Brokers, and each Portfolio's ability to
purchase securities being underwritten by an Affiliated Broker or to utilize the
Affiliated Brokers for agency transactions would be subject to restrictions.
OpCap Advisors does not believe that the restrictions on transactions with the
Affiliated Brokers described above will materially adversely affect its ability,
post-closing, to provide services to the Fund, the ability of the Portfolios to
take advantage of market opportunities, or the overall performance of the
Portfolios.

The consummation of the Allianz Transaction is subject to the approval of the
public unitholders of PAH, as well as to certain regulatory and client
approvals, and other conditions customary to transactions of this kind.

This Prospectus will be supplemented or revised if the Allianz Transaction does
not occur

substantially as set forth above.

OpCap Advisors has been in business as an investment adviser since 1987 and
Oppenheimer Capital has been in business as an investment adviser since 1969.

OpCap Advisors manages the investments of certain Portfolios (and places
brokerage orders) and conducts the business affairs of the Fund. Employees of
Oppenheimer Capital, PIMCO Advisors and OpCap Advisors perform these services.

Each Portfolio pays OpCap Advisors fees in return for providing or arranging for
the provision of investment advisory services. OpCap also pays a portion of its
advisory fees to PIMCO in return for the advisory services PIMCO performs for
the Managed Portfolio. The Portfolios of the Fund listed below paid OpCap
Advisors the following fees as a percentage of average daily net assets during
the fiscal year ended December 31, 1999:

<TABLE>
          <S>                                                       <C>
          Equity Portfolio..........................................0.80%
          Small Cap Portfolio.......................................0.80%

          Managed Portfolio.........................................0.77%
          U.S. Government Income Portfolio..........................0.60%
</TABLE>

assets of the Managed Portfolio for the advisory services PIMCO performed for
the Managed Portfolio.

The Fund pays OpCap Advisors at the annual rate of .80% of the first $400
million of average net assets, .75% on the next $400 million of average net
assets and .70% of assets in excess of $800 million with respect to the Equity,
Global Equity, Managed and Small Cap Portfolios. The rate applicable to the U.S.

                                   SHARE PRICE

The Fund calculates each Portfolio's share price, called its net asset value, on
each business day that the New York Stock Exchange is open after the close of
regular trading (generally 4:00 p.m. Eastern Standard Time). Net asset value per
share is computed by adding up the total value of a Portfolio's investments and
other assets, subtracting its liabilities and then dividing by the number of
shares outstanding.

                              TOTAL PORTFOLIO ASSETS - LIABILITIES
         Net Asset Value =  -------------------------------------------
                              NUMBER OF PORTFOLIO SHARES OUTSTANDING

The Fund uses the market prices of securities to value a Portfolio's investments
unless securities do not have market quotations or are short-term debt
securities. When the Fund uses fair value to price a security, the Fund reviews
the pricing method with the Fund's Board. The Fund prices short-term investments
that mature in less than 60 days using amortized cost or amortized value.
Foreign securities trade on days when the Portfolios do not price their shares
so the net asset value of a Portfolio's shares may change on days when
shareholders will not be able to buy or sell shares of the Portfolio. If an
event occurs after the close of the New York Stock Exchange that the Fund
believes changes the value of a security, then the Fund will value the security
at what it believes to be fair value.


                             DISTRIBUTIONS AND TAXES

This discussion is about distributions to the Portfolio's shareholders, which
are variable accounts of insurance companies and qualified pension and
retirement plans. You should read the prospectus for the variable account for
information about distributions and federal tax treatment for contract owners of
variable products.

Each Portfolio pays dividends from its net investment income and distributes any
net capital gains that it has realized at least once a year. The U.S. Government
Income Portfolio pays dividends from its net investment income once a month.


                              FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the
Portfolio's financial performance. Certain information reflects financial
results for a single Portfolio share. The total


                                       18

returns in the table represent the rate that an investor would have earned
(or lost) on an investment in a Portfolio (assuming reinvestment of all
dividends and distributions). The information in the financial highlights table
below has been audited by PricewaterhouseCoopers LLP, independent accountants,
whose report, along with the Portfolio's financial statements, is incorporated
by reference in the Fund's SAI, which is available upon request.

PRINCIPAL INVESTMENT
STRATEGIES                          -   The Small Cap Portfolio invests
                                        primarily in equity securities of
                                        companies with market capitalizations
                                        under $1 billion.

                                    -   The Managed Portfolio invests in common
                                        stocks, bonds and cash equivalents,
                                        allocated based on the investment
                                        adviser's judgment.


INVESTMENT
PHILOSOPHY                          OpCap Advisors is the investment adviser to
                                    all of the Portfolios. OpCap Advisors has
                                    retained Pacific Investment Management
                                    Company ("PIMCO") as sub-adviser for a
                                    portion of the assets of the Managed
                                    Portfolio.

                                    For the equity investments it manages
                                    directly, i.e., the Small Cap Portfolio and
                                    the portion of the assets of the Managed
                                    Portfolio not sub-advised by its affiliates,
                                    OpCap Advisors applies principles of value
                                    investing, although the individual portfolio
                                    managers may implement those principles
                                    differently.

                                    When selecting equity securities, OpCap
                                    Advisors believes there are two major
                                    components of value.

                                    -   A company's ability to generate earnings
                                        that contribute to shareholder value.
                                        OpCap Advisors considers discretionary
                                        cash flow-cash that remains after a
                                        company spends what is needed to sustain
                                        its industrial position as a primary
                                        determinant of a company's potential to
                                        add economic value.

                                    -   Price - OpCap Advisors looks for market
                                        undervaluation great enough to offer the
                                        potential for upside reward with what it
                                        believes is modest downward risk.

                                    OpCap Advisors uses fundamental company
                                    analysis to select securities. Fundamental
                                    company analysis involves intensive
                                    evaluation of historic financial data
                                    including:

                                    -   Company financial statements

                                    OpCap Advisors uses fundamental company
                                    analysis to select companies they believe
                                    have one or more of the following
                                    characteristics:

                                    -   substantial and growing discretionary
                                        cash flow
                                    -   strong shareholder value-oriented
                                        management
                                    -   valuable consumer or commercial
                                        franchises
                                    -   high returns on capital
                                    -   favorable price to intrinsic value
                                        relationship.

                                    In selecting debt securities, OpCap Advisors
                                    analyzes yield relationships between
                                    different sectors and among securities along
                                    the yield curve. OpCap Advisors seeks to
                                    take advantage of maturities and individual
                                    issues that are inexpensive and have the
                                    potential to provide superior returns. In
                                    evaluating high yield debt securities, OpCap
                                    Advisors supplements its traditional credit
                                    analysis with an evaluation of an issuer's
                                    asset values.

                                    There can be no assurance that OpCap
                                    Advisors will achieve its goals.

                                    PIMCO acts as the sub-adviser to the Managed
                                    Portfolio. In selecting securities for the
                                    Managed Portfolio, PIMCO develops an outlook
                                    for interest rates, currency exchange rates
                                    and the economy; analyzes credit and call
                                    risks, and uses other security selection
                                    techniques. The proportion of the
                                    Portfolio's assets committed to investment
                                    in securities with particular
                                    characteristics (such as quality, section
                                    interest rate or maturity) varies based on
                                    PIMCO's outlook for the U.S. economy and the
                                    economies of other countries in the world,
                                    the financial markets and other factors.

                                    PIMCO attempts to identify areas of the bond
                                    market that are undervalued relative to the
                                    rest of the market. PIMCO identifies these
                                    areas by grouping bonds into the following
                                    sectors: money markets, governments,
                                    corporates, mortgages, asset-backed and
                                    international. Sophisticated proprietary
                                    software then assists in evaluating sectors
                                    and pricing specific securities. Once
                                    investment opportunities are identified,
                                    PIMCO will shift assets among sectors
                                    depending upon changes in relative
                                    valuations and credit spreads.

                                    There is no guarantee that PIMCO's security
                                    selection techniques will produce the
                                    desired results.

PRINCIPAL RISKS                     If you invest in the Portfolios that invest
                                    in equity securities, you could lose money
                                    or those Portfolios could underperform other
                                    investments if any of the following happens:

                                    -  The stock market goes down
                                    -  The Portfolio's investment style (i.e.,
                                       value or growth) falls out of favor with
                                       the stock market
                                    -  The Portfolio's investment sector (e.g.,
                                       small cap, mid cap or foreign securities,
                                       which generally are more volatile than
                                       U.S. large cap securities) declines or
                                       becomes less liquid
                                    -  For the Small Cap and Managed Portfolios,
                                       the market undervalues the stocks held
                                       for longer than expected, or the stocks
                                       purchased turn out not to be undervalued
                                    -  The stocks selected for growth potential
                                       do not achieve such growth.

                                    If you invest in the Portfolios that invest
                                    in debt securities, you could lose money or
                                    your investment may underperform other
                                    investments if any of the following happens:

                                    -  Interest rates rise and the bond market
                                       goes down
                                    -  Issuers of debt instruments cannot meet
                                       their obligations
                                    -  Bond issuers' call bonds selling at a
                                       premium to their call price before the
                                       maturity date
                                    -  Loans securing mortgage-backed
                                       obligations prepay principal more rapidly
                                       than expected. The Portfolios may have to
                                       reinvest these prepayments at lower
                                       rates.

BAR CHART &
PERFORMANCE
TABLE
                     The bar charts provide some indication of the risks of
                     investing in the Portfolios by showing changes in the
                     performance of each Portfolio's shares from year to year
                     for the life of each Portfolio and the highest and lowest
                     quarterly return during the life of each Portfolio.

                     The Portfolios' past performance does not necessarily
                     indicate how each Portfolio will perform in the future. The
                     Portfolios' performance does not reflect charges and
                     deductions which are imposed under the variable contracts.

*On September 16, 1994, an investment company then called Quest for Value
Accumulation Trust (the "Old Trust") was effectively divided into two investment
funds, the Old Trust and the Fund, at which time the Fund commenced operations.
The total net assets for each of the Small Cap and Managed Portfolios
immediately after the transaction were $139,812,573 and $682,601,380,
respectively, with respect to the Old Trust and for each of the Small Cap and
Managed Portfolios, $8,129,274 and $51,345,102, respectively, with respect to
the Fund. For the period prior to September 16, 1994, the performance figures
above for each of the Small Cap and Managed Portfolios reflect the performance
of the corresponding Portfolios of the Old Trust. The Old Trust commenced
operations on August 1, 1988.

The benchmark for the portion of the Managed Portfolio managed by PIMCO is the
Lehman Brothers Aggregate Bond Index.

                         PRINCIPAL INVESTMENT STRATEGIES

SMALL CAP PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Capital appreciation through a diversified portfolio consisting primarily
     of securities of companies with market capitalizations of under $1 billion
     at time of purchase.

Q    What is the Portfolio's investment program?

A    The Portfolio invests primarily in equity securities of companies with
     market capitalizations under $1 billion at the time of purchase that OpCap
     Advisors believes are undervalued in the marketplace. The Portfolio may
     purchase securities listed on U.S. or foreign securities exchanges or
     traded in the U.S. or foreign over the counter markets. The Portfolio also
     may purchase securities in initial public offerings or shortly after those
     offerings have been completed.


                                       7
<PAGE>

Q    What are the potential rewards of investing in the Portfolio?

A    Common stocks offer a way to invest for long term growth of capital.
     Opportunities for value creation for small cap companies could result from
     product expansion or product improvement, industry transition, new
     management or sale of the company. Small cap companies are followed by
     fewer analysts than are large and mid cap companies. So as additional
     analysts follow a small cap stock, investor demand for the stock may
     increase.


MANAGED PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Growth of capital over time through investment in a portfolio consisting of
     common stocks, bonds and cash equivalents, the percentages of which will
     vary based on OpCap Advisors' and PIMCO's assessments of the relative
     outlook for such investments.

Q    What is the Portfolio's investment program?

A    The Portfolio seeks to meet its objective by investing in common stocks,
     bonds and cash equivalents in varying percentages based on OpCap Advisors'
     and PIMCO's view of relative values. The Portfolio may purchase securities
     listed on U.S. or foreign securities exchanges or traded in the U.S. or
     foreign over the counter markets. The Portfolio also may purchase
     investment grade U.S. government and corporate bonds and high quality money
     market securities. The Portfolio can invest up to 100% of its assets in
     debt securities but will only do so if equity securities are not an
     attractive investment.

Q    What are the potential rewards of investing in the Portfolio?

A    The Portfolio normally invests mainly in equity securities. Common stocks
     offer a way to invest for long term growth of capital.


                                      RISKS

Q    What are the risks of investing in the Portfolios?

A    The Small Cap and Managed Portfolios invest principally in equity
     securities which may be affected by the following:

     STOCK MARKET VOLATILITY - The stock market in general may fluctuate in
     response to political, market and economic developments and you can lose
     money on your investments.

     Equity investors should have a long-term investment horizon and should be
     prepared for the ups and downs of the stock market.


                                       8
<PAGE>

     STOCK PICKING - The portfolio manager may select stocks that have prices
     that turn out not to be undervalued or do not achieve expectations for
     growth in income or revenues.

     ISSUER CHANGES - Changes in the financial condition of an issuer or changes
     in economic conditions that affect a particular type of issuer can affect
     the value or credit quality of an issuer's securities.

     SMALL CAP AND MID CAP VOLATILITY - Mid cap stocks are more volatile and
     have less trading volume than large cap stocks. Small cap stocks are more
     volatile and have less trading volume than both large cap and mid cap
     stocks.

     SECTOR RISK - OpCap Advisors are bottom up investment managers. That means
     that they select securities for a Portfolio based on the investment merits
     of a particular issue rather than the business sector.

     INVESTMENT STYLES - Value or growth stocks may be out of favor for a period
     of time. Both investment styles can produce poor returns for a period of
     time.

     ASSET ALLOCATION RISK - The Managed Portfolio invest in a mix of equity and
     fixed income securities. The portfolio manager of the Managed Portfolio can
     make the wrong allocation decisions.

     FOREIGN EXPOSURE - When selecting foreign securities for the Portfolios,
     OpCap Advisors use approximately the same standards that they set for U.S.
     issuers. Foreign securities, foreign currencies and securities issued by
     U.S. entities with substantial foreign operations may have additional risks
     than U.S. securities.

         -    Political Risk - Foreign governments can take over the assets or
              operations of a company or may impose taxes or limits on the
              removal of the Portfolio's assets from that country.

         -    Currency risk - The value of securities held in foreign currencies
              will be affected by changes in the value of that currency.

         -    Liquidity - Some foreign markets are less liquid and more
              volatile than the U.S. stock market.

         -    Limited information - There may be less public information about
              foreign issuers than there is about U.S. issuers.

         -    Settlement and clearance - Some foreign markets experience delays
              in settlement. These delays could cause the Portfolio to miss
              investment opportunities or to be unable to sell a security.

         -    Euro - The effect of the Euro on international markets has not
              yet been determined.


                                       9
<PAGE>

         -    Emerging Markets - There are greater risks of unstable governments
              and economies and restriction on foreign ownership in these
              countries. The Portfolios presently intend to limit investment in
              emerging markets to no more than 5% of their total assets.

To the extent that the Portfolios invest in debt securities, the Portfolios are
exposed to these risks:

         -    Interest rate risk - The risk that changes in interest rates will
              affect the value of fixed income securities in the Portfolio.

         -    Prepayment risk - The risk that the holder of a mortgage
              underlying a mortgage backed security will prepay principal.

         -    Credit risk - The risk that an issuer of a fixed income security
              will be unable to pay principal and interest payments when they
              are due.


                               INVESTMENT POLICIES

Q    Can a Portfolio change its investment objective and investment policies?

A    Fundamental policies of a Portfolio cannot be changed without the approval
     of a majority of the outstanding voting shares of the Portfolio. A
     Portfolio's investment objective is a fundamental policy. Investment
     restrictions that are fundamental policies are listed in the Statement of
     Additional Information. Investment policies are not fundamental and can be
     changed by the Fund's Board of Trustees.

Q    Can the Portfolios use derivative instruments?

A    Yes. The Small Cap and Managed Portfolios may use the following derivative
     instruments:

     -   futures contracts
     -   options on futures contracts
     -   forward foreign currency contracts
     -   covered calls written on individual securities
     -   uncovered calls and puts
     -   options on stock indices.

     The Small Cap Portfolio does not expect to use derivative instruments
     significantly, if at all. The Managed Portfolio will sometimes use
     derivative instruments as part of a strategy designed to reduce exposure to
     other risks, such as interest risk or currency risk, and may use derivative
     instruments to meet their investment objectives.

Q    What are the risks of derivative instruments?


                                       10
<PAGE>

A    Derivative instruments can reduce the return of a Portfolio if :

     -   Its investment adviser uses a derivative instrument at the wrong time
     -   The prices of a Portfolio's futures or options positions are not
         correlated with its other investments
     -   A Portfolio cannot close out a position because of an illiquid market.

Q    Do the Portfolios expect to engage in short-term trading?

A    The Portfolios do not expect to engage in frequent short-term trading. The
     Financial Highlights table in this prospectus shows the turnover rates
     during prior fiscal years for the Portfolios that were active during this
     period.

Q    Can the Portfolios vary from their investment goals?

A    When a Portfolio's investment adviser or subadviser thinks market or
     economic conditions are adverse, it may invest up to 100% of its assets in
     defensive investments such as U.S. Government securities and money market
     instruments. To the extent that a Portfolio takes a defensive position, it
     will not be pursuing its investment objective.


                                 FUND MANAGEMENT

OPCAP ADVISORS

The Board of Trustees of the Fund has hired OpCap Advisors to serve as manager
of the Fund.

OpCap Advisors is a subsidiary of Oppenheimer Capital, an investment advisory
firm with approximately $53 billion of assets under management as of December
31, 1999. They are indirect wholly-owned subsidiaries of PIMCO Advisors L.P. The
mailing address is 1345 Avenue of the Americas, New York, New York 10105.

The general partners of PIMCO Advisors L.P. are PIMCO Partners G.P. and PIMCO
Advisors Holding L.P. ("PAH"). PIMCO Partners, G.P. is a general partnership
between PIMCO Holdings LLC, a Delaware limited liability company and an indirect
wholly-owned subsidiary of Pacific Life Insurance Company, and PIMCO Partners
LLC, a California limited liability company controlled by the current Managing
Directors and two former Managing Directors of Pacific Investment Management
Company, a subsidiary of PIMCO Advisors L.P. PIMCO Partners, G.P. is the sole
general partner of PAH.

On October 31, 1999, PIMCO Advisors L.P., PAH and Allianz AG ("Allianz")
announced that they had reached a definitive agreement pursuant to which Allianz
will acquire majority ownership of PIMCO Advisors L.P. and its subsidiaries,
including OpCap Advisors (the "Allianz Transaction"). Under the terms of the
transaction, Allianz will acquire all of PAH, the publicly traded general
partner of PIMCO Advisors L.P. Pacific Life Insurance Company will retain an


                                       11
<PAGE>

approximately 30% interest in PIMCO Advisors L.P. The Allianz Transaction is
currently expected to be completed by on or about May 5, 2000.

Allianz is the world's second largest insurance company and a leading provider
of financial services, particularly in Europe, and is represented in 68
countries world-wide through subsidiaries, branch and representative offices,
and other affiliated entities. Allianz currently has assets under management of
more than $390 billion, and in its last fiscal year wrote approximately $50
billion in gross insurance premiums. After consummation of the transaction, the
combined firms will have over $650 billion in assets under management.

Affiliates of Allianz currently include Dresdner Bank AG, Deutsche Bank AG,
Munich Re, and Hypo Vereinsbank. These entities, as well as certain broker-
dealers controlled by or affiliated with these entities, such as Bankers Trust
Company and BT Alex Brown, Inc. are considered the "Affiliated Brokers." Once
the Allianz transaction is consummated, absent an SEC exemption or other relief,
the Fund's Portfolios would generally be precluded from effecting principal
transactions with the Affiliated Brokers, and each Portfolio's ability to
purchase securities being underwritten by an Affiliated Broker or to utilize the
Affiliated Brokers for agency transactions would be subject to restrictions.
OpCap Advisors does not believe that the restrictions on transactions with the
Affiliated Brokers described above will materially adversely affect its ability,
post-closing, to provide services to the Fund, the ability of the Portfolios to
take advantage of market opportunities, or the overall performance of the
Portfolios.

The consummation of the Allianz Transaction is subject to the approval of the
public unitholders of PAH, as well as to certain regulatory and client
approvals, and other conditions customary to transactions of this kind.

This Prospectus will be supplemented or revised if the Allianz Transaction does
not occur substantially as set forth above.

OpCap Advisors has been in business as an investment adviser since 1987 and
Oppenheimer Capital has been in business as an investment adviser since 1969.

OpCap Advisors manages the investments of certain Portfolios (and places
brokerage orders) and conducts the business affairs of the Fund. Employees of
Oppenheimer Capital, PIMCO Advisors and OpCap Advisors perform these services.

Each Portfolio pays OpCap Advisors fees in return for providing or arranging for
the provision of investment advisory services. OpCap also pays a portion of its
advisory fees to PIMCO in return for the advisory services PIMCO performs for
the Managed Portfolio. The Portfolios of the Fund listed below paid OpCap
Advisors the following fees as a percentage of average daily net assets during
the fiscal year ended December 31, 1999:

<TABLE>

</TABLE>


                                       12
<PAGE>

OpCap will pay PIMCO a fee at the annual rate of 0.25% of the average daily net
assets of the Managed Portfolio for the advisory services PIMCO performed for
the Managed Portfolio.

The Fund pays OpCap Advisors at the annual rate of .80% of the first $400
million of average net assets, .75% on the next $400 million of average net
assets and .70% of assets in excess of $800 million with respect to the Managed
and Small Cap Portfolios.

                                   SHARE PRICE

The Fund calculates each Portfolio's share price, called its net asset value, on
each business day that the New York Stock Exchange is open after the close of
regular trading (generally 4:00 p.m. Eastern Standard Time). Net asset value per
share is computed by adding up the total value of a Portfolio's investments and
other assets, subtracting its liabilities and then dividing by the number of
shares outstanding.

                                TOTAL PORTFOLIO ASSETS - LIABILITIES
           Net Asset Value =  -----------------------------------------
                                NUMBER OF PORTFOLIO SHARES OUTSTANDING

The Fund uses the market prices of securities to value a Portfolio's investments
unless securities do not have market quotations or are short-term debt
securities. When the Fund uses fair value to price a security, the Fund reviews
the pricing method with the Fund's Board. The Fund prices short-term investments
that mature in less than 60 days using amortized cost or amortized value.
Foreign securities trade on days when the Portfolios do not price their shares
so the net asset value of a Portfolio's shares may change on days when
shareholders will not be able to buy or sell shares of the Portfolio. If an
event occurs after the close of the New York Stock Exchange that the Fund
believes changes the value of a security, then the Fund will value the security
at what it believes to be fair value.


                             DISTRIBUTIONS AND TAXES

This discussion is about distributions to the Portfolio's shareholders, which
are variable accounts of insurance companies and qualified pension and
retirement plans. You should read the prospectus for the variable account for
information about distributions and federal tax treatment for contract owners of
variable products.


                                       14

Each Portfolio pays dividends from its net investment income and distributes any
net capital gains that it has realized at least once a year.


                              FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the
Portfolio's financial performance. Certain information reflects financial
results for a single Portfolio share. The total returns in the table represent
the rate that an investor would have earned (or lost) on an investment in a
Portfolio (assuming reinvestment of all dividends and distributions). The
information in the financial highlights table below has been audited by
PricewaterhouseCoopers LLP, independent accountants, whose report, along with
the Portfolio's financial statements, is incorporated by reference in the Fund's
SAI, which is available upon request.

                            i.e., the Small Cap Portfolio and the portion of the
                            assets of the Managed Portfolio not sub-advised by
                            its affiliates, OpCap Advisors applies principles of
                            value investing, although the individual portfolio
                            managers may implement those principles differently.

                            When selecting equity securities, OpCap Advisors
                            believes there are two major components of value.

                            -  A company's ability to generate earnings that
                               contribute to shareholder value. OpCap Advisors
                               considers discretionary cash flow-cash that
                               remains after a company spends what is needed to
                               sustain its industrial position as a primary
                               determinant of a company's potential to add
                               economic value.

                               believes is modest downward risk.

                            OpCap Advisors uses fundamental company analysis to
                            select securities. Fundamental company analysis
                            involves intensive evaluation of historic financial
                            data including:

                            -  Company financial statements
                            -  Market share analysis
                            -  Unit volume growth
                            -  Barriers to entry
                            -  Pricing policies
                            -  Management record.

                            OpCap Advisors uses fundamental company analysis to
                            select companies they believe have one or more of
                            the following characteristics:

                            -  substantial and growing discretionary cash flow
                            -  strong shareholder value-oriented management
                            -  valuable consumer or commercial franchises
                            -  high returns on capital
                            -  favorable price to intrinsic value relationship.

                            In selecting debt securities, OpCap Advisors
                            analyzes yield relationships between different
                            sectors and among securities along the yield curve.
                            OpCap Advisors seeks to take advantage of maturities
                            and individual issues that are inexpensive and have
                            the potential to provide superior returns. In
                            evaluating high yield debt securities, OpCap
                            Advisors supplements its traditional credit analysis
                            with an evaluation of an issuer's asset values.

                            There can be no assurance that OpCap Advisors will
                            achieve its goals.

                            PIMCO acts as the sub-adviser to the Managed
                            Portfolio. In selecting securities for the Managed
                            Portfolio, PIMCO develops an outlook for interest
                            rates, currency exchange rates and the economy;
                            analyzes credit and call risks, and uses other
                            security selection techniques. The proportion of the
                            Portfolio's assets committed to investment in
                            securities with particular characteristics (such as
                            quality, section interest rate or maturity) varies
                            based on PIMCO's outlook for the U.S. economy and
                            the economies of other countries in the world, the
                            financial markets and other factors.

                            PIMCO attempts to identify areas of the bond market
                            that are


                                       4
<PAGE>

                            undervalued relative to the rest of the market.
                            PIMCO identifies these areas by grouping bonds into
                            the following sectors: money markets, governments,
                            corporates, mortgages, asset-backed and
                            international. Sophisticated proprietary software
                            then assists in evaluating sectors and pricing
                            specific securities. Once investment opportunities
                            are identified, PIMCO will shift assets among
                            sectors depending upon changes in relative
                            valuations and credit spreads. There is no guarantee
                            that PIMCO's security selection techniques will
                            produce the desired results.

PRINCIPAL RISKS             If you invest in the Portfolios that invest in
                            equity securities, you could lose money or those
                            Portfolios could underperform other investments if
                            any of the following happens:

                            -  The stock market goes down
                            -  The Portfolio's investment style (i.e., value or
                               growth) falls out of favor with the stock market
                            -  The Portfolio's investment sector (e.g., small
                               cap, mid cap or foreign securities, which
                               generally are more volatile than U.S. large cap
                               securities) declines or becomes less liquid
                            -  For the Small Cap and Managed Portfolios, the
                               market undervalues the stocks held for longer
                               than expected, or the stocks purchased turn out
                               not to be undervalued
                            -  The stocks selected for growth potential do not
                               achieve such growth.

                            If you invest in the Portfolios that invest in debt
                            securities, you could lose money or your investment
                            may underperform other investments if any of the
                            following happens:

                            -  Interest rates rise and the bond market goes down
                            -  Issuers of debt instruments cannot meet their
                               obligations
                            -  Bond issuers' call bonds selling at a premium to
                               their call price before the maturity date
                            -  Loans securing mortgage-backed obligations prepay
                               principal more rapidly than expected. The
                               Portfolios may have to reinvest these prepayments
                               at lower rates.

                            The U.S. Government Income Portfolio principally
                            buys fixed income securities that are issued or
                            guaranteed by the U.S. Government or its agencies or
                            instrumentalities, so credit risk should be low.

BAR CHART &
PERFORMANCE
TABLE
                The bar charts provide some indication of the risks of investing
                in the Portfolios by showing changes in the performance of each
                Portfolio's shares from year to year for the life of each
                Portfolio and the highest and lowest quarterly return during the
                life of each Portfolio.

                The Portfolios' past performance does not necessarily indicate
                how each Portfolio will perform in the future. The Portfolios'
                performance does not reflect charges and deductions which are
                imposed under the variable contracts.

*On September 16, 1994, an investment company then called Quest for Value
Accumulation Trust (the "Old Trust") was effectively divided into two investment
funds, the Old Trust and the Fund, at which time the Fund commenced operations.
The total net assets for each of the Small Cap and Managed Portfolios
immediately after the transaction were $139,812,573 and $682,601,380,
respectively, with respect to the Old Trust and for each of the Small Cap and
Managed Portfolios, $8,129,274 and $51,345,102, respectively, with respect to
the Fund. For the period prior to September 16, 1994, the performance figures
above for each of the Small Cap and Managed Portfolios reflect the performance
of the corresponding Portfolios of the Old Trust. The Old Trust commenced
operations on August 1, 1988.

The benchmark for the portion of the Managed Portfolio managed by PIMCO is the
Lehman Brothers Aggregate Bond Index.

                         PRINCIPAL INVESTMENT STRATEGIES

SMALL CAP PORTFOLIO

Q  What is the Portfolio's investment objective?

A  Capital appreciation through a diversified portfolio consisting primarily of
   securities of companies with market capitalizations of under $1 billion at
   time of purchase.

Q  What is the Portfolio's investment program?

A  The Portfolio invests primarily in equity securities of companies with market
   capitalizations under $1 billion at the time of purchase that OpCap Advisors
   believes are undervalued in the marketplace. The Portfolio may purchase
   securities listed on U.S. or foreign securities exchanges or traded in the
   U.S. or foreign over the counter markets. The Portfolio also may purchase
   securities in initial public offerings or shortly after those offerings have
   been completed.

Q  What are the potential rewards of investing in the Portfolio?

A  Common stocks offer a way to invest for long term growth of capital.
   Opportunities for value creation for small cap companies could result from
   product expansion or product improvement, industry transition, new management
   or sale of the company. Small cap companies are followed by fewer analysts
   than are large and mid cap companies. So as additional analysts follow a
   small cap stock, investor demand for the stock may increase.

MANAGED PORTFOLIO

Q  What is the Portfolio's investment objective?

A  Growth of capital over time through investment in a portfolio consisting of
   common stocks, bonds and cash equivalents, the percentages of which will vary
   based on OpCap Advisors' and PIMCO's assessments of the relative outlook for
   such investments.

Q  What is the Portfolio's investment program?

A  The Portfolio seeks to meet its objective by investing in common stocks,
   bonds and cash equivalents in varying percentages based on OpCap Advisors'
   and PIMCO's view of relative values. The Portfolio may purchase securities
   listed on U.S. or foreign securities exchanges or traded in the U.S. or
   foreign over the counter markets. The Portfolio also may purchase investment
   grade U.S. government and corporate bonds and high quality money market
   securities. The Portfolio can invest up to 100% of its assets in debt
   securities but will only do so if equity securities are not an attractive
   investment.

Q  What are the potential rewards of investing in the Portfolio?

A  The Portfolio normally invests mainly in equity securities. Common stocks
   offer a way to invest for long term growth of capital.


U.S. GOVERNMENT INCOME PORTFOLIO

Q  What is the Portfolio's investment objective?

A  High level of current income together with protection of capital by investing
   exclusively in debt obligations, including mortgage-backed securities issued
   or guaranteed by the United States government, its agencies or
   instrumentalities.

Q  What is the Portfolio's investment program?

A  The Portfolio invests in debt obligations issued or guaranteed by the United
   States Government, its agencies or instrumentalities. These securities are
   referred to as "U.S. Government Securities." The Portfolio also may purchase
   mortgage-backed securities to effectuate this program.

   OpCap Advisors observes current and historical yield relationships between
   maturities and sectors to seek the best relative values. The Portfolio
   generally maintains an average maturity between five and ten years. OpCap
   Advisors does not attempt to forecast interest rates in managing the
   Portfolio.

Q  What are the potential rewards of investing in the Portfolio?


                                       9
<PAGE>

A  The Portfolio consists of the highest quality debt instruments. Since the
   average maturity of the Portfolio's investments are between five and ten
   years, the Portfolio should be less volatile than a longer term bond fund.


                                     RISKS

Q  What are the risks of investing in the Portfolios?

A  The Small Cap and Managed Portfolios invest principally in equity securities
   which may be affected by the following:

   STOCK MARKET VOLATILITY - The stock market in general may fluctuate in
   response to political, market and economic developments and you can lose
   money on your investments.

   Equity investors should have a long-term investment horizon and should be
   prepared for the ups and downs of the stock market.

   STOCK PICKING - The portfolio manager may select stocks that have prices that
   turn out not to be undervalued or do not achieve expectations for growth in
   income or revenues.

   ISSUER CHANGES - Changes in the financial condition of an issuer or changes
   in economic conditions that affect a particular type of issuer can affect the
   value or credit quality of an issuer's securities.

   SMALL CAP AND MID CAP VOLATILITY - Mid cap stocks are more volatile and have
   less trading volume than large cap stocks. Small cap stocks are more volatile
   and have less trading volume than both large cap and mid cap stocks.

   SECTOR RISK - OpCap Advisors are bottom up investment managers. That means
   that they select securities for a Portfolio based on the investment merits of
   a particular issue rather than the business sector.

   INVESTMENT STYLES - Value or growth stocks may be out of favor for a period
   of time. Both investment styles can produce poor returns for a period of
   time.

   ASSET ALLOCATION RISK - The Managed Portfolio invest in a mix of equity and
   fixed income securities. The portfolio manager of the Managed Portfolio can
   make the wrong allocation decisions.

   FOREIGN EXPOSURE - When selecting foreign securities for the Portfolio, OpCap
   Advisors use approximately the same standards that they set for U.S. issuers.
   Foreign securities, foreign currencies and securities issued by U.S. entities
   with substantial foreign operations may have additional risks than U.S.
   securities.

      -   Political Risk - Foreign governments can take over the assets or
          operations of a


                                       10
<PAGE>

          company or may impose taxes or limits on the removal of the
          Portfolio's assets from that country.

      -   Currency risk - The value of securities held in foreign currencies
          will be affected by changes in the value of that currency.

      -   Liquidity - Some foreign markets are less liquid and more volatile
          than the U.S. stock market.

      -   Limited information - There may be less public information about
          foreign issuers than there is about U.S. issuers.

      -   Settlement and clearance - Some foreign markets experience delays in
          settlement. These delays could cause the Portfolio to miss investment
          opportunities or to be unable to sell a security.

      -   Euro - The effect of the Euro on international markets has not yet
          been determined.

      -   Emerging Markets - There are greater risks of unstable governments and
          economies and restriction on foreign ownership in these countries. The
          Portfolios presently intend to limit investment in emerging markets to
          no more than 5% of their total assets.

To the extent that the Portfolios invest in debt securities, the Portfolios are
exposed to these risks:

      -   Interest rate risk - The risk that changes in interest rates will
          affect the value of fixed income securities in the Portfolio.

      -   Prepayment risk - The risk that the holder of a mortgage underlying a
          mortgage backed security will prepay principal.

      -   Credit risk - The risk that an issuer of a fixed income security will
          be unable to pay principal and interest payments when they are due.



                               INVESTMENT POLICIES

Q  Can a Portfolio change its investment objective and investment policies?

A  Fundamental policies of a Portfolio cannot be changed without the approval of
   a majority of the outstanding voting shares of the Portfolio. A Portfolio's
   investment objective is a fundamental policy. Investment restrictions that
   are fundamental policies are listed in the Statement of Additional
   Information. Investment policies are not fundamental and can be changed by
   the Fund's Board of Trustees.


                                       11
<PAGE>

Q  Can the Portfolios use derivative instruments?

A  Yes. The Small Cap and Managed and Portfolios may use the following
   derivative instruments:

     -  futures contracts
     -  options on futures contracts
     -  forward foreign currency contracts
     -  covered calls written on individual securities
     -  uncovered calls and puts
     -  options on stock indices.

     The Small Cap Portfolio does not expect to use derivative instruments
     significantly, if at all. The Managed Portfolio will sometimes use
     derivative instruments as part of a strategy designed to reduce exposure to
     other risks, such as interest risk or currency risk, and may use derivative
     instruments to meet their investment objectives.

Q  What are the risks of derivative instruments?

A  Derivative instruments can reduce the return of a Portfolio if :

     -  Its investment adviser uses a derivative instrument at the wrong time
     -  The prices of a Portfolio's futures or options positions are not
        correlated with its other investments
     -  A Portfolio cannot close out a position because of an illiquid market.

Q  Do the Portfolios expect to engage in short-term trading?

A  The Portfolios do not expect to engage in frequent short-term trading. The
   Financial Highlights table in this prospectus shows the turnover rates during
   prior fiscal years for the Portfolios that were active during this period.

Q  Can the Portfolios vary from their investment goals?

A  When a Portfolio's investment adviser or subadviser thinks market or economic
   conditions are adverse, it may invest up to 100% of its assets in defensive
   investments such as U.S. Government securities and money market instruments.
   To the extent that a Portfolio takes a defensive position, it will not be
   pursuing its investment objective.


                                 FUND MANAGEMENT

OPCAP ADVISORS

The Board of Trustees of the Fund has hired OpCap Advisors to serve as manager
of the Fund.


                                       12
<PAGE>

OpCap Advisors is a subsidiary of Oppenheimer Capital, an investment advisory
firm with approximately $53 billion of assets under management as of
December 31, 1999. They are indirect wholly-owned subsidiaries of PIMCO Advisors
L.P. The mailing address is 1345 Avenue of the Americas, New York, New
York 10105.

The general partners of PIMCO Advisors L.P. are PIMCO Partners G.P. and PIMCO
Advisors Holding L.P. ("PAH"). PIMCO Partners, G.P. is a general partnership
between PIMCO Holdings LLC, a Delaware limited liability company and an indirect
wholly-owned subsidiary of Pacific Life Insurance Company, and PIMCO Partners
LLC, a California limited liability company controlled by the current Managing
Directors and two former Managing Directors of Pacific Investment Management
Company, a subsidiary of PIMCO Advisors L.P. PIMCO Partners, G.P. is the sole
general partner of PAH.

On October 31, 1999, PIMCO Advisors L.P., PAH and Allianz AG ("Allianz")
announced that they had reached a definitive agreement pursuant to which Allianz
will acquire majority ownership of PIMCO Advisors L.P. and its subsidiaries,
including OpCap Advisors (the "Allianz Transaction"). Under the terms of the
transaction, Allianz will acquire all of PAH, the publicly traded general
partner of PIMCO Advisors L.P. Pacific Life Insurance Company will retain an
approximately 30% interest in PIMCO Advisors L.P. The Allianz Transaction is
currently expected to be completed by on or about May 5, 2000.

Allianz is the world's second largest insurance company and a leading provider
of financial services, particularly in Europe, and is represented in 68
countries world-wide through subsidiaries, branch and representative offices,
and other affiliated entities. Allianz currently has assets under management of
more than $390 billion, and in its last fiscal year wrote approximately $50
billion in gross insurance premiums. After consummation of the transaction, the
combined firms will have over $650 billion in assets under management.

Affiliates of Allianz currently include Dresdner Bank AG, Deutsche Bank AG,
Munich Re, and Hypo Vereinsbank. These entities, as well as certain broker-
dealers controlled by or affiliated with these entities, such as Bankers Trust
Company and BT Alex Brown, Inc. are considered the "Affiliated Brokers." Once
the Allianz transaction is consummated, absent an SEC exemption or other relief,
the Fund's Portfolios would generally be precluded from effecting principal
transactions with the Affiliated Brokers, and each Portfolio's ability to
purchase securities being underwritten by an Affiliated Broker or to utilize the
Affiliated Brokers for agency transactions would be subject to restrictions.
OpCap Advisors does not believe that the restrictions on transactions with the
Affiliated Brokers described above will materially adversely affect its ability,
post-closing, to provide services to the Fund, the ability of the Portfolios to
take advantage of market opportunities, or the overall performance of the
Portfolios.

The consummation of the Allianz Transaction is subject to the approval of the
public unitholders of PAH, as well as to certain regulatory and client
approvals, and other conditions customary to transactions of this kind.

This Prospectus will be supplemented or revised if the Allianz Transaction does
not occur

Oppenheimer Capital has been in business as an investment adviser since 1969.

OpCap Advisors manages the investments of certain Portfolios (and places
brokerage orders) and conducts the business affairs of the Fund. Employees of
Oppenheimer Capital, PIMCO Advisors and OpCap Advisors perform these services.

Each Portfolio pays OpCap Advisors fees in return for providing or arranging for
the provision of investment advisory services. OpCap also pays a portion of its
advisory fees to PIMCO in return for the advisory services PIMCO performs for
the Managed Portfolio. The Portfolios of the Fund listed below paid OpCap
Advisors the following fees as a percentage of average daily net assets during
the fiscal year ended December 31, 1999:

<TABLE>
         <S>                                                          <C>
         Small Cap Portfolio..........................................0.80%
         Managed Portfolio............................................0.77%
         U.S. Government Income Portfolio.............................0.60%
</TABLE>

assets of the Managed Portfolio for the advisory services PIMCO performed for
the Managed Portfolio.

million of average net assets, .75% on the next $400 million of average net
assets and .70% of assets in excess of $800 million with respect to the Managed
and Small Cap Portfolios. The rate applicable to the U.S. Government Income

                                   SHARE PRICE

The Fund calculates each Portfolio's share price, called its net asset value, on
each business day that the New York Stock Exchange is open after the close of
regular trading (generally 4:00 p.m. Eastern Standard Time). Net asset value per
share is computed by adding up the total value of a Portfolio's investments and
other assets, subtracting its liabilities and then dividing by the number of
shares outstanding.

                              TOTAL PORTFOLIO ASSETS - LIABILITIES
         Net Asset Value =  -------------------------------------------
                              NUMBER OF PORTFOLIO SHARES OUTSTANDING

The Fund uses the market prices of securities to value a Portfolio's investments
unless securities do not have market quotations or are short-term debt
securities. When the Fund uses fair value to price a security, the Fund reviews
the pricing method with the Fund's Board. The Fund prices short-term investments
that mature in less than 60 days using amortized cost or amortized value.
Foreign securities trade on days when the Portfolios do not price their shares
so the net asset value of a Portfolio's shares may change on days when
shareholders will not be able to buy or sell shares of the Portfolio. If an
event occurs after the close of the New York Stock Exchange that the Fund
believes changes the value of a security, then the Fund will value the security
at what it believes to be fair value.


                             DISTRIBUTIONS AND TAXES

This discussion is about distributions to the Portfolio's shareholders, which
are variable accounts of insurance companies and qualified pension and
retirement plans. You should read the prospectus for the variable account for
information about distributions and federal tax treatment for contract owners of
variable products.

Each Portfolio pays dividends from its net investment income and distributes any
net capital gains that it has realized at least once a year. The U.S. Government
Income Portfolio pays dividends from its net investment income once a month.


                              FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the
Portfolio's financial performance. Certain information reflects financial
results for a single Portfolio share. The total returns in the table represent
the rate that an investor would have earned (or lost) on an

PRINCIPAL INVESTMENT
STRATEGIES                  -  The Small Cap Portfolio invests primarily in
                               equity securities of companies with market
                               capitalizations under $1 billion.

                            -  The Global Equity Portfolio invests primarily in
                               equity securities on a worldwide basis and may
                               invest in U.S. or foreign fixed income
                               securities.

                            -  The Managed Portfolio invests in common stocks,
                               bonds and cash equivalents, allocated based on
                               the investment adviser's judgment.


INVESTMENT
PHILOSOPHY                  OpCap Advisors is the investment adviser to all of
                            the Portfolios. OpCap Advisors has retained Pacific
                            Investment Management Company ("PIMCO") as
                            sub-adviser for a portion of the assets of the
                            Managed Portfolio.

                            For the equity investments it manages directly,
                            i.e., the Small Cap and Global Equity Portfolios and
                            the portion of the assets of the Managed Portfolio
                            not sub-advised by its affiliates, OpCap Advisors
                            applies principles of value investing, although the
                            individual portfolio managers may implement those
                            principles differently.

                            When selecting equity securities, OpCap Advisors
                            believes there are two major components of value.

                            -  A company's ability to generate earnings that
                               contribute to shareholder value. OpCap Advisors
                               considers discretionary cash flow-cash that
                               remains after a company spends what is needed to
                               sustain its industrial position as a primary
                               determinant of a company's potential to add
                               economic value.

                            -  Price - OpCap Advisors looks for market
                               undervaluation great enough to offer the
                               potential for upside reward with what it

                               believes is modest downward risk.

                            OpCap Advisors uses fundamental company analysis to
                            select securities. Fundamental company analysis
                            involves intensive evaluation of historic financial
                            data including:

                            -  Company financial statements
                            -  Market share analysis
                            -  Unit volume growth
                            -  Barriers to entry
                            -  Pricing policies
                            -  Management record.

                            OpCap Advisors uses fundamental company analysis to
                            select companies they believe have one or more of
                            the following characteristics:

                            -  substantial and growing discretionary cash flow
                            -  strong shareholder value-oriented management
                            -  valuable consumer or commercial franchises
                            -  high returns on capital
                            -  favorable price to intrinsic value relationship.

                            In selecting debt securities, OpCap Advisors
                            analyzes yield relationships between different
                            sectors and among securities along the yield curve.
                            OpCap Advisors seeks to take advantage of maturities
                            and individual issues that are inexpensive and have
                            the potential to provide superior returns. In
                            evaluating high yield debt securities, OpCap
                            Advisors supplements its traditional credit analysis
                            with an evaluation of an issuer's asset values.

                            There can be no assurance that OpCap Advisors will
                            achieve its goals.

                            PIMCO acts as the sub-adviser to the Managed
                            Portfolio. In selecting securities for the Managed
                            Portfolio, PIMCO develops an outlook for interest
                            rates, currency exchange rates and the economy;
                            analyzes credit and call risks, and uses other
                            security selection techniques. The proportion of the
                            Portfolio's assets committed to investment in
                            securities with particular characteristics (such as
                            quality, section interest rate or maturity) varies
                            based on PIMCO's outlook for the U.S. economy and
                            the economies of other countries in the world, the
                            financial markets and other factors.

                            PIMCO attempts to identify areas of the bond market
                            that are


                                       4
<PAGE>

                            undervalued relative to the rest of the market.
                            PIMCO identifies these areas by grouping bonds into
                            the following sectors: money markets, governments,
                            corporates, mortgages, asset-backed and
                            international. Sophisticated proprietary software
                            then assists in evaluating sectors and pricing
                            specific securities. Once investment opportunities
                            are identified, PIMCO will shift assets among
                            sectors depending upon changes in relative
                            valuations and credit spreads. There is no guarantee
                            that PIMCO's security selection techniques will
                            produce the desired results.

PRINCIPAL RISKS             If you invest in the Portfolios that invest in
                            equity securities, you could lose money or those
                            Portfolios could underperform other investments if
                            any of the following happens:

                            -  The stock market goes down
                            -  The Portfolio's investment style (i.e., value or
                               growth) falls out of favor with the stock market
                            -  The Portfolio's investment sector (e.g., small
                               cap, mid cap or foreign securities, which
                               generally are more volatile than U.S. large cap
                               securities) declines or becomes less liquid
                            -  For the Small Cap, Global Equity and Managed
                               Portfolios, the market undervalues the stocks
                               held for longer than expected, or the stocks
                               purchased turn out not to be undervalued
                            -  The stocks selected for growth potential do not
                               achieve such growth.

                            If you invest in the Portfolios that invest in debt
                            securities, you could lose money or your investment
                            may underperform other investments if any of the
                            following happens:

                            -  Interest rates rise and the bond market goes down
                            -  Issuers of debt instruments cannot meet their
                               obligations
                            -  Bond issuers' call bonds selling at a premium to
                               their call price before the maturity date
                            -  Loans securing mortgage-backed obligations prepay
                               principal more rapidly than expected. The
                               Portfolios may have to reinvest these prepayments
                               at lower rates.

                The bar charts provide some indication of the risks of investing
                in the Portfolios by showing changes in the performance of each
                Portfolio's shares from year to year for the life of each
                Portfolio and the highest and lowest quarterly return during the
                life of each Portfolio.

*On September 16, 1994, an investment company then called Quest for Value
Accumulation Trust (the "Old Trust") was effectively divided into two investment
funds, the Old Trust and the Fund, at which time the Fund commenced operations.
The total net assets for each of the Small Cap and Managed Portfolios
immediately after the transaction were $139,812,573 and $682,601,380,
respectively, with respect to the Old Trust and for each of the Small Cap and

                         PRINCIPAL INVESTMENT STRATEGIES

SMALL CAP PORTFOLIO

Q  What is the Portfolio's investment objective?

A  Capital appreciation through a diversified portfolio consisting primarily of
   securities of companies with market capitalizations of under $1 billion at
   time of purchase.

Q  What is the Portfolio's investment program?

A  The Portfolio invests primarily in equity securities of companies with market
   capitalizations under $1 billion at the time of purchase that OpCap Advisors
   believes are undervalued in the


                                       8
<PAGE>

   marketplace. The Portfolio may purchase securities listed on U.S. or foreign
   securities exchanges or traded in the U.S. or foreign over the counter
   markets. The Portfolio also may purchase securities in initial public
   offerings or shortly after those offerings have been completed.

Q  What are the potential rewards of investing in the Portfolio?

A  Common stocks offer a way to invest for long term growth of capital.
   Opportunities for value creation for small cap companies could result from
   product expansion or product improvement, industry transition, new management
   or sale of the company. Small cap companies are followed by fewer analysts
   than are large and mid cap companies. So as additional analysts follow a
   small cap stock, investor demand for the stock may increase.


GLOBAL EQUITY PORTFOLIO

Q  What is the Portfolio's investment objective?

A  Long term capital appreciation through pursuit of a global investment
   strategy primarily involving equity securities.

Q  What is the Portfolio's investment program?

A  The Portfolio invests primarily in equity securities of companies located
   throughout the world which OpCap Advisors believes are undervalued in the
   marketplace. The Portfolio may invest up to 35% of its total assets in fixed
   income securities which may be lower than investment grade.

Q  What are the potential rewards of investing in the Portfolio?

A  Foreign securities provide additional opportunities and diversification. U.S.
   stocks represent less than half of the world's stock market capitalization.


MANAGED PORTFOLIO

Q  What is the Portfolio's investment objective?

A  Growth of capital over time through investment in a portfolio consisting of
   common stocks, bonds and cash equivalents, the percentages of which will vary
   based on OpCap Advisors' and PIMCO's assessments of the relative outlook for
   such investments.

Q  What is the Portfolio's investment program?

A  The Portfolio seeks to meet its objective by investing in common stocks,
   bonds and cash equivalents in varying percentages based on OpCap Advisors'
   and PIMCO's view of relative


                                       9
<PAGE>

   values. The Portfolio may purchase securities listed on U.S. or foreign
   securities exchanges or traded in the U.S. or foreign over the counter
   markets. The Portfolio also may purchase investment grade U.S. government and
   corporate bonds and high quality money market securities. The Portfolio can
   invest up to 100% of its assets in debt securities but will only do so if
   equity securities are not an attractive investment.

Q  What are the potential rewards of investing in the Portfolio?

A  The Portfolio normally invests mainly in equity securities. Common stocks
   offer a way to invest for long term growth of capital.


                                      RISKS

Q  What are the risks of investing in the Portfolios?

A  The Small Cap, Global Equity and Managed Portfolios invest principally in
   equity securities which may be affected by the following:

   STOCK MARKET VOLATILITY - The stock market in general may fluctuate in
   response to political, market and economic developments and you can lose
   money on your investments.

   Equity investors should have a long-term investment horizon and should be
   prepared for the ups and downs of the stock market.

   STOCK PICKING - The portfolio manager may select stocks that have prices that
   turn out not to be undervalued or do not achieve expectations for growth in
   income or revenues.

   ISSUER CHANGES - Changes in the financial condition of an issuer or changes
   in economic conditions that affect a particular type of issuer can affect the
   value or credit quality of an issuer's securities.

   SMALL CAP AND MID CAP VOLATILITY - Mid cap stocks are more volatile and have
   less trading volume than large cap stocks. Small cap stocks are more volatile
   and have less trading volume than both large cap and mid cap stocks.

   SECTOR RISK - OpCap Advisors are bottom up investment managers. That means
   that they select securities for a Portfolio based on the investment merits of
   a particular issue rather than the business sector.

   INVESTMENT STYLES - Value or growth stocks may be out of favor for a period
   of time. Both investment styles can produce poor returns for a period of
   time.

   ASSET ALLOCATION RISK - The Managed Portfolio invest in a mix of equity and
   fixed income securities. The portfolio manager of the Managed Portfolio can
   make the wrong allocation decisions.


                                       10
<PAGE>

   FOREIGN EXPOSURE - When selecting foreign securities for the Portfolios,
   OpCap Advisors use approximately the same standards that they set for U.S.
   issuers. Foreign securities, foreign currencies and securities issued by U.S.
   entities with substantial foreign operations may have additional risks than
   U.S. securities. This risk is greater for the Global Equity Portfolio which
   invests on a worldwide basis.

     -   Political Risk - Foreign governments can take over the assets or
         operations of a company or may impose taxes or limits on the removal of
         the Portfolio's assets from that country.

     -   Currency risk - The value of securities held in foreign currencies will
         be affected by changes in the value of that currency.

     -   Liquidity - Some foreign markets are less liquid and more volatile than
         the U.S. stock market.

     -   Limited information - There may be less public information about
         foreign issuers than there is about U.S. issuers.

     -   Settlement and clearance - Some foreign markets experience delays in
         settlement. These delays could cause the Portfolio to miss investment
         opportunities or to be unable to sell a security.

     -   Euro - The effect of the Euro on international markets has not yet been
         determined.

     -   Emerging Markets - There are greater risks of unstable governments and
         economies and restriction on foreign ownership in these countries. The
         Portfolios presently intend to limit investment in emerging markets to
         no more than 5% of their total assets.

To the extent that the Portfolios invest in debt securities, the Portfolios are
exposed to these risks:

     -   Interest rate risk - The risk that changes in interest rates will
         affect the value of fixed income securities in the Portfolio.

     -   Prepayment risk - The risk that the holder of a mortgage underlying a
         mortgage backed security will prepay principal.

     -   Credit risk - The risk that an issuer of a fixed income security will
         be unable to pay principal and interest payments when they are due.

To the extent that the Global Equity Portfolio invests in lower grade debt
securities, you should know that lower grade debt may have the following
additional risks:


                                       11
<PAGE>

     -   more volatility

     -   less liquidity

     -   greater risk of issuer default or insolvency.


                               INVESTMENT POLICIES

Q  Can a Portfolio change its investment objective and investment policies?

A  Fundamental policies of a Portfolio cannot be changed without the approval of
   a majority of the outstanding voting shares of the Portfolio. A Portfolio's
   investment objective is a fundamental policy. Investment restrictions that
   are fundamental policies are listed in the Statement of Additional
   Information. Investment policies are not fundamental and can be changed by
   the Fund's Board of Trustees.

Q  Can the Portfolios use derivative instruments?

A  Yes. The Small Cap, Global Equity and Managed Portfolios may use the
   following derivative instruments:

    -  futures contracts
    -  options on futures contracts
    -  forward foreign currency contracts
    -  covered calls written on individual securities
    -  uncovered calls and puts
    -  options on stock indices.

   The Small Cap and Global Equity Portfolios do not expect to use derivative
   instruments significantly, if at all. The Managed Portfolio will sometimes
   use derivative instruments as part of a strategy designed to reduce
   exposure to other risks, such as interest risk or currency risk, and may
   use derivative instruments to meet their investment objectives.

Q  What are the risks of derivative instruments?

A  Derivative instruments can reduce the return of a Portfolio if :

    -  Its investment adviser uses a derivative instrument at the wrong time
    -  The prices of a Portfolio's futures or options positions are not
       correlated with its other investments
    -  A Portfolio cannot close out a position because of an illiquid market.

Q  Do the Portfolios expect to engage in short-term trading?

A  The Portfolios do not expect to engage in frequent short-term trading. The
   Financial


                                       12
<PAGE>

   Highlights table in this prospectus shows the turnover rates during prior
   fiscal years for the Portfolios that were active during this period.

Q  Can the Portfolios vary from their investment goals?

A  When a Portfolio's investment adviser or subadviser thinks market or economic
   conditions are adverse, it may invest up to 100% of its assets in defensive
   investments such as U.S. Government securities and money market instruments.
   To the extent that a Portfolio takes a defensive position, it will not be
   pursuing its investment objective.


                                 FUND MANAGEMENT

OPCAP ADVISORS

The Board of Trustees of the Fund has hired OpCap Advisors to serve as manager
of the Fund.

OpCap Advisors is a subsidiary of Oppenheimer Capital, an investment advisory
firm with approximately $53 billion of assets under management as of
December 31, 1999. They are indirect wholly-owned subsidiaries of PIMCO Advisors
L.P. The mailing address is 1345 Avenue of the Americas, New York, New
York 10105.

The general partners of PIMCO Advisors L.P. are PIMCO Partners G.P. and PIMCO
Advisors Holding L.P. ("PAH"). PIMCO Partners, G.P. is a general partnership
between PIMCO Holdings LLC, a Delaware limited liability company and an indirect
wholly-owned subsidiary of Pacific Life Insurance Company, and PIMCO Partners
LLC, a California limited liability company controlled by the current Managing
Directors and two former Managing Directors of Pacific Investment Management
Company, a subsidiary of PIMCO Advisors L.P. PIMCO Partners, G.P. is the sole
general partner of PAH.

On October 31, 1999, PIMCO Advisors L.P., PAH and Allianz AG ("Allianz")
announced that they had reached a definitive agreement pursuant to which Allianz
will acquire majority ownership of PIMCO Advisors L.P. and its subsidiaries,
including OpCap Advisors (the "Allianz Transaction"). Under the terms of the
transaction, Allianz will acquire all of PAH, the publicly traded general
partner of PIMCO Advisors L.P. Pacific Life Insurance Company will retain an
approximately 30% interest in PIMCO Advisors L.P. The Allianz Transaction is
currently expected to be completed by on or about May 5, 2000.

Allianz is the world's second largest insurance company and a leading provider
of financial services, particularly in Europe, and is represented in 68
countries world-wide through subsidiaries, branch and representative offices,
and other affiliated entities. Allianz currently has assets under management of
more than $390 billion, and in its last fiscal year wrote approximately $50
billion in gross insurance premiums. After consummation of the transaction, the
combined firms will have over $650 billion in assets under management.

Affiliates of Allianz currently include Dresdner Bank AG, Deutsche Bank AG,
Munich Re, and


                                       13
<PAGE>

Hypo Vereinsbank. These entities, as well as certain broker- dealers controlled
by or affiliated with these entities, such as Bankers Trust Company and BT Alex
Brown, Inc. are considered the "Affiliated Brokers." Once the Allianz
transaction is consummated, absent an SEC exemption or other relief, the Fund's
Portfolios would generally be precluded from effecting principal transactions
with the Affiliated Brokers, and each Portfolio's ability to purchase securities
being underwritten by an Affiliated Broker or to utilize the Affiliated Brokers
for agency transactions would be subject to restrictions. OpCap Advisors does
not believe that the restrictions on transactions with the Affiliated Brokers
described above will materially adversely affect its ability, post-closing, to
provide services to the Fund, the ability of the Portfolios to take advantage of
market opportunities, or the overall performance of the Portfolios.

The consummation of the Allianz Transaction is subject to the approval of the
public unitholders of PAH, as well as to certain regulatory and client
approvals, and other conditions customary to transactions of this kind.

This Prospectus will be supplemented or revised if the Allianz Transaction does
not occur substantially as set forth above.

OpCap Advisors has been in business as an investment adviser since 1987 and
Oppenheimer Capital has been in business as an investment adviser since 1969.

OpCap Advisors manages the investments of certain Portfolios (and places
brokerage orders) and conducts the business affairs of the Fund. Employees of
Oppenheimer Capital, PIMCO Advisors and OpCap Advisors perform these services.

Each Portfolio pays OpCap Advisors fees in return for providing or arranging for
the provision of investment advisory services. OpCap also pays a portion of its
advisory fees to PIMCO in return for the advisory services PIMCO performs for
the Managed Portfolio. The Portfolios of the Fund listed below paid OpCap
Advisors the following fees as a percentage of average daily net assets during
the fiscal year ended December 31, 1999:

<TABLE>
         <S>                                                      <C>
         Small Cap Portfolio......................................0.80%
         Global Equity Portfolio..................................0.80%
         Managed Portfolio........................................0.77%
</TABLE>

OpCap will pay PIMCO a fee at the annual rate of 0.25% of the average daily net
assets of the Managed Portfolio for the advisory services PIMCO performed for
the Managed Portfolio.

The Fund pays OpCap Advisors at the annual rate of .80% of the first $400
million of average net assets, .75% on the next $400 million of average net
assets and .70% of assets in excess of $800 million with respect to the Global
Equity, Managed and Small Cap Portfolios.

                           manager of the Managed Portfolio since March 2000.

                                   SHARE PRICE

The Fund calculates each Portfolio's share price, called its net asset value, on
each business day that the New York Stock Exchange is open after the close of
regular trading (generally 4:00 p.m. Eastern Standard Time). Net asset value per
share is computed by adding up the total value of a Portfolio's investments and
other assets, subtracting its liabilities and then dividing by the number of
shares outstanding.

                              TOTAL PORTFOLIO ASSETS - LIABILITIES
         Net Asset Value =  -------------------------------------------
                              NUMBER OF PORTFOLIO SHARES OUTSTANDING

The Fund uses the market prices of securities to value a Portfolio's investments
unless securities do not have market quotations or are short-term debt
securities. When the Fund uses fair value to price a security, the Fund reviews
the pricing method with the Fund's Board. The Fund prices short-term investments
that mature in less than 60 days using amortized cost or amortized value.
Foreign securities trade on days when the Portfolios do not price their shares
so the net asset value of a Portfolio's shares may change on days when
shareholders will not be able to buy or sell shares of the Portfolio. If an
event occurs after the close of the New York Stock Exchange that the Fund
believes changes the value of a security, then the Fund will value the security
at what it believes to be fair value.


                             DISTRIBUTIONS AND TAXES

This discussion is about distributions to the Portfolio's shareholders, which
are variable accounts of insurance companies and qualified pension and
retirement plans. You should read the prospectus for the variable account for
information about distributions and federal tax treatment


                                       16
<PAGE>

for contract owners of variable products.

Each Portfolio pays dividends from its net investment income and distributes any
net capital gains that it has realized at least once a year.


                              FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the
Portfolio's financial performance. Certain information reflects financial
results for a single Portfolio share. The total returns in the table represent
the rate that an investor would have earned (or lost) on an investment in a
Portfolio (assuming reinvestment of all dividends and distributions). The
information in the financial highlights table below has been audited by
PricewaterhouseCoopers LLP, independent accountants, whose report, along with
the Portfolio's financial statements, is incorporated by reference in the Fund's
SAI, which is available upon request.

INVESTMENT
PHILOSOPHY                          OpCap Advisors is the investment adviser to
                                    all of the Portfolios. OpCap Advisors has
                                    retained Pacific Investment Management
                                    Company ("PIMCO") as sub-adviser for a
                                    portion of the assets of the Managed
                                    Portfolio.

                                    For the equity investments it manages
                                    directly, i.e., the Equity and Small Cap
                                    Portfolios and the portion of the assets of
                                    the Managed Portfolio not sub-advised by its
                                    affiliates, OpCap Advisors applies
                                    principles of value investing, although the
                                    individual portfolio managers may implement
                                    those principles differently.

                                    When selecting equity securities, OpCap
                                    Advisors believes there are two major
                                    components of value.

                                    -   A company's ability to generate earnings
                                        that contribute to shareholder value.
                                        OpCap Advisors considers discretionary
                                        cash flow-cash that remains after a
                                        company spends what is needed to sustain
                                        its industrial position as a primary
                                        determinant of a company's potential to
                                        add economic value.

                                    -   Price - OpCap Advisors looks for market
                                        undervaluation great enough to offer the
                                        potential for upside reward with what it
                                        believes is modest downward risk.

                                    OpCap Advisors uses fundamental company
                                    analysis to select

                                    securities. Fundamental company analysis
                                    involves intensive evaluation of historic
                                    financial data including:

                                    -   Company financial statements
                                    -   Market share analysis
                                    -   Unit volume growth
                                    -   Barriers to entry
                                    -   Pricing policies
                                    -   Management record.

                                    OpCap Advisors uses fundamental company
                                    analysis to select companies they believe
                                    have one or more of the following
                                    characteristics:

                                    -   substantial and growing discretionary
                                        cash flow
                                    -   strong shareholder value-oriented
                                        management
                                    -   valuable consumer or commercial
                                        franchises
                                    -   high returns on capital
                                    -   favorable price to intrinsic value
                                        relationship.

                                    In selecting debt securities, OpCap Advisors
                                    analyzes yield relationships between
                                    different sectors and among securities along
                                    the yield curve. OpCap Advisors seeks to
                                    take advantage of maturities and individual
                                    issues that are inexpensive and have the
                                    potential to provide superior returns. In
                                    evaluating high yield debt securities, OpCap
                                    Advisors supplements its traditional credit
                                    analysis with an evaluation of an issuer's
                                    asset values.

                                    There can be no assurance that OpCap
                                    Advisors will achieve its goals.

                                    PIMCO acts as the sub-adviser to the Managed
                                    Portfolio. In selecting securities for the
                                    Managed Portfolio, PIMCO develops an outlook
                                    for interest rates, currency exchange rates
                                    and the economy; analyzes credit and call
                                    risks, and uses other security selection
                                    techniques. The proportion of the
                                    Portfolio's assets committed to investment
                                    in securities with particular
                                    characteristics (such as quality, section
                                    interest rate or maturity) varies based on
                                    PIMCO's outlook for the U.S. economy and the
                                    economies of other countries in the world,
                                    the financial markets and other factors.

                                    PIMCO attempts to identify areas of the bond
                                    market that are undervalued relative to the
                                    rest of the market. PIMCO identifies these
                                    areas by grouping bonds into the following
                                    sectors: money markets, governments,
                                    corporates, mortgages, asset-backed and

                                    international. Sophisticated proprietary
                                    software then assists in evaluating sectors
                                    and pricing specific securities. Once
                                    investment opportunities are identified,
                                    PIMCO will shift assets among sectors
                                    depending upon changes in relative
                                    valuations and credit spreads. There is no
                                    guarantee that PIMCO's security selection
                                    techniques will produce the desired results.

PRINCIPAL RISKS                     If you invest in the Portfolios that invest
                                    in equity securities, you could lose money
                                    or those Portfolios could underperform other
                                    investments if any of the following happens:

                                    -  The stock market goes down
                                    -  The Portfolio's investment style (i.e.,
                                       value or growth) falls out of favor with
                                       the stock market
                                    -  The Portfolio's investment sector (e.g.,
                                       small cap, mid cap or foreign securities,
                                       which generally are more volatile than
                                       U.S. large cap securities) declines or
                                       becomes less liquid
                                    -  For the Equity, Small Cap and Managed
                                       Portfolios, the market undervalues the
                                       stocks held for longer than expected, or
                                       the stocks purchased turn out not to be
                                       undervalued
                                    -  The stocks selected for growth potential
                                       do not achieve such growth.

                                    If you invest in the Portfolios that invest
                                    in debt securities, you could lose money or
                                    your investment may underperform other
                                    investments if any of the following happens:

                                    -  Interest rates rise and the bond market
                                       goes down
                                    -  Issuers of debt instruments cannot meet
                                       their obligations
                                    -  Bond issuers' call bonds selling at a
                                       premium to their call price before the
                                       maturity date
                                    -  Loans securing mortgage-backed
                                       obligations prepay principal more rapidly
                                       than expected. The Portfolios may have to
                                       reinvest these prepayments at lower
                                       rates.

BAR CHART &
PERFORMANCE
TABLE
                     The bar charts provide some indication of the risks of
                     investing in the Portfolios by showing changes in the
                     performance of each Portfolio's shares from year to year
                     for the life of each Portfolio and the highest and lowest
                     quarterly return during the life of each Portfolio.

                     The Portfolios' past performance does not necessarily
                     indicate how each Portfolio will perform in the future. The
                     Portfolios' performance does not reflect charges and
                     deductions which are imposed under the variable contracts.

                         PRINCIPAL INVESTMENT STRATEGIES

EQUITY PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Long term capital appreciation through investment in a diversified
     portfolio of equity securities selected on the basis of a value approach to
     investing.

Q    What is the Portfolio's investment program?

A    The Equity Portfolio invests primarily in equity securities of companies
     that OpCap Advisors believes are undervalued in the marketplace. Under
     normal conditions, the Portfolio will invest at least 65% of its total
     assets in equity securities listed on the New York Stock Exchange. The
     Portfolio also may purchase securities listed on other U.S. or foreign
     securities exchanges or traded in the U.S. or foreign over the counter
     markets.

     The Equity Portfolio is managed to follow a composite portfolio constructed
     by a group of senior portfolio managers at OpCap Advisors.

Q    What are the potential rewards of investing in the Portfolio?

A    Common stocks and other equity securities offer a way to invest for long
     term growth of capital. Equity investors should have a long term investment
     horizon and should be prepared for the ups and downs of the stock markets.


SMALL CAP PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Capital appreciation through a diversified portfolio consisting primarily
     of securities of companies with market capitalizations of under $1 billion
     at time of purchase.


                                       8
<PAGE>

Q    What is the Portfolio's investment program?

A    The Portfolio invests primarily in equity securities of companies with
     market capitalizations under $1 billion at the time of purchase that OpCap
     Advisors believes are undervalued in the marketplace. The Portfolio may
     purchase securities listed on U.S. or foreign securities exchanges or
     traded in the U.S. or foreign over the counter markets. The Portfolio also
     may purchase securities in initial public offerings or shortly after those
     offerings have been completed.

Q    What are the potential rewards of investing in the Portfolio?

A    Common stocks offer a way to invest for long term growth of capital.
     Opportunities for value creation for small cap companies could result from
     product expansion or product improvement, industry transition, new
     management or sale of the company. Small cap companies are followed by
     fewer analysts than are large and mid cap companies. So as additional
     analysts follow a small cap stock, investor demand for the stock may
     increase.


MANAGED PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Growth of capital over time through investment in a portfolio consisting of
     common stocks, bonds and cash equivalents, the percentages of which will
     vary based on OpCap Advisors' and PIMCO's assessments of the relative
     outlook for such investments.

Q    What is the Portfolio's investment program?

A    The Portfolio seeks to meet its objective by investing in common stocks,
     bonds and cash equivalents in varying percentages based on OpCap Advisors'
     and PIMCO's view of relative values. The Portfolio may purchase securities
     listed on U.S. or foreign securities exchanges or traded in the U.S. or
     foreign over the counter markets. The Portfolio also may purchase
     investment grade U.S. government and corporate bonds and high quality money
     market securities. The Portfolio can invest up to 100% of its assets in
     debt securities but will only do so if equity securities are not an
     attractive investment.

Q    What are the potential rewards of investing in the Portfolio?

A    The Portfolio normally invests mainly in equity securities. Common stocks
     offer a way to invest for long term growth of capital.

                                      RISKS

Q    What are the risks of investing in the Portfolios?

A   The Equity, Small Cap and Managed Portfolios invest principally in equity
    securities which may be affected by the following:

     STOCK MARKET VOLATILITY - The stock market in general may fluctuate in
     response to political, market and economic developments and you can lose
     money on your investments.

     Equity investors should have a long-term investment horizon and should be
     prepared for the ups and downs of the stock market.

     STOCK PICKING - The portfolio manager may select stocks that have prices
     that turn out not to be undervalued or do not achieve expectations for
     growth in income or revenues.

     ISSUER CHANGES - Changes in the financial condition of an issuer or changes
     in economic conditions that affect a particular type of issuer can affect
     the value or credit quality of an issuer's securities.

     SMALL CAP AND MID CAP VOLATILITY - Mid cap stocks are more volatile and
     have less trading volume than large cap stocks. Small cap stocks are more
     volatile and have less trading volume than both large cap and mid cap
     stocks.

     SECTOR RISK - OpCap Advisors are bottom up investment managers. That means
     that they select securities for a Portfolio based on the investment merits
     of a particular issue rather than the business sector.

     INVESTMENT STYLES - Value or growth stocks may be out of favor for a period
     of time. Both investment styles can produce poor returns for a period of
     time.

     ASSET ALLOCATION RISK - The Managed Portfolio invest in a mix of equity and
     fixed income securities. The portfolio manager of the Managed Portfolio can
     make the wrong allocation decisions.

     FOREIGN EXPOSURE - When selecting foreign securities for the Portfolio,
     OpCap Advisors use approximately the same standards that they set for U.S.
     issuers. Foreign securities, foreign currencies and securities issued by
     U.S. entities with substantial foreign operations may have additional risks
     than U.S. securities.

         -    Political Risk - Foreign governments can take over the assets or
              operations of a company or may impose taxes or limits on the
              removal of the Portfolio's assets from that country.

         -    Currency risk - The value of securities held in foreign currencies
              will be affected by changes in the value of that currency.


                                       10
<PAGE>

         -    Liquidity - Some foreign markets are less liquid and more
              volatile than the U.S. stock market.

         -    Limited information - There may be less public information about
              foreign issuers than there is about U.S. issuers.

         -    Settlement and clearance - Some foreign markets experience delays
              in settlement. These delays could cause the Portfolio to miss
              investment opportunities or to be unable to sell a security.

         -    Euro - The effect of the Euro on international markets has not
              yet been determined.

         -    Emerging Markets - There are greater risks of unstable governments
              and economies and restriction on foreign ownership in these
              countries. The Portfolios presently intend to limit investment in
              emerging markets to no more than 5% of their total assets.

To the extent that the Portfolios invest in debt securities, the Portfolios are
exposed to these risks:

         -    Interest rate risk - The risk that changes in interest rates will
              affect the value of fixed income securities in the Portfolio.

         -    Prepayment risk - The risk that the holder of a mortgage
              underlying a mortgage backed security will prepay principal.

         -    Credit risk - The risk that an issuer of a fixed income security
              will be unable to pay principal and interest payments when they
              are due.


                               INVESTMENT POLICIES

Q   Can a Portfolio change its investment objective and investment policies?

A   Fundamental policies of a Portfolio cannot be changed without the approval
    of a majority of the outstanding voting shares of the Portfolio. A
    Portfolio's investment objective is a fundamental policy. Investment
    restrictions that are fundamental policies are listed in the Statement of
    Additional Information. Investment policies are not fundamental and can be
    changed by the Fund's Board of Trustees.

Q    Can the Portfolios use derivative instruments?

A    Yes. The Equity, Small Cap and Managed Portfolios may use the following
     derivative instruments:


                                       11
<PAGE>

     -   futures contracts
     -   options on futures contracts
     -   forward foreign currency contracts
     -   covered calls written on individual securities
     -   uncovered calls and puts
     -   options on stock indices.

     The Equity and Small Cap Portfolios do not expect to use derivative
     instruments significantly, if at all. The Managed Portfolio will sometimes
     use derivative instruments as part of a strategy designed to reduce
     exposure to other risks, such as interest risk or currency risk, and may
     use derivative instruments to meet their investment objectives.

Q    What are the risks of derivative instruments?

A    Derivative instruments can reduce the return of a Portfolio if :

     -   Its investment adviser uses a derivative instrument at the wrong time
     -   The prices of a Portfolio's futures or options positions are not
         correlated with its other investments
     -   A Portfolio cannot close out a position because of an illiquid market.

Q    Do the Portfolios expect to engage in short-term trading?

A    The Portfolios do not expect to engage in frequent short-term trading. The
     Financial Highlights table in this prospectus shows the turnover rates
     during prior fiscal years for the Portfolios that were active during this
     period.

Q    Can the Portfolios vary from their investment goals?

A    When a Portfolio's investment adviser or subadviser thinks market or
     economic conditions are adverse, it may invest up to 100% of its assets in
     defensive investments such as U.S. Government securities and money market
     instruments. To the extent that a Portfolio takes a defensive position, it
     will not be pursuing its investment objective.


                                 FUND MANAGEMENT

OPCAP ADVISORS

The Board of Trustees of the Fund has hired OpCap Advisors to serve as manager
of the Fund.

OpCap Advisors is a subsidiary of Oppenheimer Capital, an investment advisory
firm with approximately $53 billion of assets under management as of December
31, 1999. They are indirect wholly-owned subsidiaries of PIMCO Advisors L.P. The
mailing address is 1345 Avenue of the Americas, New York, New York 10105.


                                       12
<PAGE>

The general partners of PIMCO Advisors L.P. are PIMCO Partners G.P. and PIMCO
Advisors Holding L.P. ("PAH"). PIMCO Partners, G.P. is a general partnership
between PIMCO Holdings LLC, a Delaware limited liability company and an indirect
wholly-owned subsidiary of Pacific Life Insurance Company, and PIMCO Partners
LLC, a California limited liability company controlled by the current Managing
Directors and two former Managing Directors of Pacific Investment Management
Company, a subsidiary of PIMCO Advisors L.P. PIMCO Partners, G.P. is the sole
general partner of PAH.

On October 31, 1999, PIMCO Advisors L.P., PAH and Allianz AG ("Allianz")
announced that they had reached a definitive agreement pursuant to which Allianz
will acquire majority ownership of PIMCO Advisors L.P. and its subsidiaries,
including OpCap Advisors (the "Allianz Transaction"). Under the terms of the
transaction, Allianz will acquire all of PAH, the publicly traded general
partner of PIMCO Advisors L.P. Pacific Life Insurance Company will retain an
approximately 30% interest in PIMCO Advisors L.P. The Allianz Transaction is
currently expected to be completed by on or about May 5, 2000.

Allianz is the world's second largest insurance company and a leading provider
of financial services, particularly in Europe, and is represented in 68
countries world-wide through subsidiaries, branch and representative offices,
and other affiliated entities. Allianz currently has assets under management of
more than $390 billion, and in its last fiscal year wrote approximately $50
billion in gross insurance premiums. After consummation of the transaction, the
combined firms will have over $650 billion in assets under management.

Affiliates of Allianz currently include Dresdner Bank AG, Deutsche Bank AG,
Munich Re, and Hypo Vereinsbank. These entities, as well as certain broker-
dealers controlled by or affiliated with these entities, such as Bankers Trust
Company and BT Alex Brown, Inc. are considered the "Affiliated Brokers." Once
the Allianz transaction is consummated, absent an SEC exemption or other relief,
the Fund's Portfolios would generally be precluded from effecting principal
transactions with the Affiliated Brokers, and each Portfolio's ability to
purchase securities being underwritten by an Affiliated Broker or to utilize the
Affiliated Brokers for agency transactions would be subject to restrictions.
OpCap Advisors does not believe that the restrictions on transactions with the
Affiliated Brokers described above will materially adversely affect its ability,
post-closing, to provide services to the Fund, the ability of the Portfolios to
take advantage of market opportunities, or the overall performance of the
Portfolios.

The consummation of the Allianz Transaction is subject to the approval of the
public unitholders of PAH, as well as to certain regulatory and client
approvals, and other conditions customary to transactions of this kind.

This Prospectus will be supplemented or revised if the Allianz Transaction does
not occur substantially as set forth above.

OpCap Advisors has been in business as an investment adviser since 1987 and
Oppenheimer Capital has been in business as an investment adviser since 1969.

OpCap Advisors manages the investments of certain Portfolios (and places
brokerage orders) and


                                       13
<PAGE>

conducts the business affairs of the Fund. Employees of Oppenheimer Capital,
PIMCO Advisors and OpCap Advisors perform these services.

Each Portfolio pays OpCap Advisors fees in return for providing or arranging for
the provision of investment advisory services. OpCap also pays a portion of its
advisory fees to PIMCO in return for the advisory services PIMCO performs for
the Managed Portfolio. The Portfolios of the Fund listed below paid OpCap
Advisors the following fees as a percentage of average daily net assets during
the fiscal year ended December 31, 1999:

<TABLE>
                <S>                                                 <C>
                Equity Portfolio....................................0.80%
                Small Cap Portfolio.................................0.80%
                Managed Portfolio...................................0.77%
</TABLE>

OpCap will pay PIMCO a fee at the annual rate of 0.25% of the average daily net
assets of the Managed Portfolio for the advisory services PIMCO performed for
the Managed Portfolio.

The Fund pays OpCap Advisors at the annual rate of .80% of the first $400
million of average net assets, .75% on the next $400 million of average net
assets and .70% of assets in excess of $800 million with respect to the Equity,
Managed and Small Cap Portfolios.

                                   SHARE PRICE

The Fund calculates each Portfolio's share price, called its net asset value, on
each business day that the New York Stock Exchange is open after the close of
regular trading (generally 4:00 p.m. Eastern Standard Time). Net asset value per
share is computed by adding up the total value of a Portfolio's investments and
other assets, subtracting its liabilities and then dividing by the number of
shares outstanding.

        Net Asset Value =    TOTAL PORTFOLIO ASSETS - LIABILITIES
                             -------------------------------------------
                             NUMBER OF PORTFOLIO SHARES OUTSTANDING

The Fund uses the market prices of securities to value a Portfolio's investments
unless securities do not have market quotations or are short-term debt
securities. When the Fund uses fair value to price a security, the Fund reviews
the pricing method with the Fund's Board. The Fund prices short-term investments
that mature in less than 60 days using amortized cost or amortized value.
Foreign securities trade on days when the Portfolios do not price their shares
so the net asset value of a Portfolio's shares may change on days when
shareholders will not be able to buy or sell shares of the Portfolio. If an
event occurs after the close of the New York Stock Exchange that the Fund
believes changes the value of a security, then the Fund will value the security
at what it believes to be fair value.


                             DISTRIBUTIONS AND TAXES

This discussion is about distributions to the Portfolio's shareholders, which
are variable accounts of insurance companies and qualified pension and
retirement plans. You should read the prospectus for the variable account for
information about distributions and federal tax treatment for contract owners of
variable products.

Each Portfolio pays dividends from its net investment income and distributes any
net capital gains that it has realized at least once a year.


                              FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the
Portfolio's financial performance. Certain information reflects financial
results for a single Portfolio share. The total returns in the table represent
the rate that an investor would have earned (or lost) on an investment in a
Portfolio (assuming reinvestment of all dividends and distributions). The
information in the financial highlights table below has been audited by
PricewaterhouseCoopers LLP, independent accountants, whose report, along with
the Portfolio's financial statements, is incorporated by reference in the Fund's
SAI, which is available upon request.

                               securities listed on the New York Stock Exchange.

                            -  The Mid Cap Portfolio invests primarily in equity

INVESTMENT
PHILOSOPHY                  OpCap Advisors is the investment adviser to all of
                            the Portfolios. OpCap Advisors has retained Pacific
                            Investment Management Company ("PIMCO") as
                            sub-adviser for a portion of the assets of the
                            Managed Portfolio.

                            For the equity investments it manages directly,
                            i.e., the Equity, Mid Cap and Small Cap Portfolios
                            and the portion of the assets of the Managed
                            Portfolios not sub-advised by its affiliates, OpCap
                            Advisors applies principles of value investing,
                            although the individual portfolio managers may
                            implement those principles differently.

                            When selecting equity securities, OpCap Advisors
                            believes there are two major components of value.

                            -  A company's ability to generate earnings that
                               contribute to shareholder value. OpCap Advisors
                               considers discretionary cash flow-cash that
                               remains after a company spends what is needed to
                               sustain its industrial position as a primary


                                       3

                               determinant of a company's potential to add
                               economic value.

                            -  Price - OpCap Advisors looks for market
                               undervaluation great enough to offer the
                               potential for upside reward with what it believes
                               is modest downward risk.

                            OpCap Advisors uses fundamental company analysis to
                            select securities. Fundamental company analysis
                            involves intensive evaluation of historic financial
                            data including:

                            -  Company financial statements
                            -  Market share analysis
                            -  Unit volume growth
                            -  Barriers to entry
                            -  Pricing policies
                            -  Management record.

                            OpCap Advisors uses fundamental company analysis to
                            select companies they believe have one or more of
                            the following characteristics:

                            -  substantial and growing discretionary cash flow
                            -  strong shareholder value-oriented management
                            -  valuable consumer or commercial franchises
                            -  high returns on capital
                            -  favorable price to intrinsic value relationship.

                            In selecting debt securities, OpCap Advisors
                            analyzes yield relationships between different
                            sectors and among securities along the yield curve.
                            OpCap Advisors seeks to take advantage of maturities
                            and individual issues that are inexpensive and have
                            the potential to provide superior returns. In
                            evaluating high yield debt securities, OpCap
                            Advisors supplements its traditional credit analysis
                            with an evaluation of an issuer's asset values.

                            There can be no assurance that OpCap Advisors will
                            achieve its goals.

                            PIMCO acts as the sub-adviser to the Managed
                            Portfolio. In selecting securities for the Managed
                            Portfolio, PIMCO develops an outlook for interest
                            rates, currency exchange rates and the economy;
                            analyzes credit and call risks, and uses other
                            security selection techniques. The proportion of the
                            Portfolio's assets committed to investment in
                            securities with particular characteristics (such as
                            quality, section interest rate or maturity) varies
                            based on PIMCO's outlook for the U.S. economy and
                            the


                                       4
<PAGE>

                            economies of other countries in the world, the
                            financial markets and other factors.

                            PIMCO attempts to identify areas of the bond market
                            that are undervalued relative to the rest of the
                            market. PIMCO identifies these areas by grouping
                            bonds into the following sectors: money markets,
                            governments, corporates, mortgages, asset-backed and
                            international. Sophisticated proprietary software
                            then assists in evaluating sectors and pricing
                            specific securities. Once investment opportunities
                            are identified, PIMCO will shift assets among
                            sectors depending upon changes in relative
                            valuations and credit spreads. There is no guarantee
                            that PIMCO's security selection techniques will
                            produce the desired results.

PRINCIPAL RISKS             If you invest in the Portfolios that invest in
                            equity securities, you could lose money or those
                            Portfolios could underperform other investments if
                            any of the following happens:

                            -  The stock market goes down
                            -  The Portfolio's investment style (i.e., value or
                               growth) falls out of favor with the stock market
                            -  The Portfolio's investment sector (e.g., small
                               cap, mid cap or foreign securities, which
                               generally are more volatile than U.S. large cap
                               securities) declines or becomes less liquid
                            -  For the Equity, Mid Cap, Small Cap and Managed
                               Portfolios, the market undervalues the stocks
                               held for longer than expected, or the stocks
                               purchased turn out not to be undervalued
                            -  The stocks selected for growth potential do not
                               achieve such growth.

                            If you invest in the Portfolios that invest in debt
                            securities, you could lose money or your investment
                            may underperform other investments if any of the
                            following happens:

                            -  Interest rates rise and the bond market goes down
                            -  Issuers of debt instruments cannot meet their
                               obligations
                            -  Bond issuers' call bonds selling at a premium to
                               their call price before the maturity date
                            -  Loans securing mortgage-backed obligations prepay
                               principal more rapidly than expected. The
                               Portfolios may have to reinvest these prepayments
                               at lower rates.

BAR CHART &
PERFORMANCE
TABLE
                 The bar charts provide some indication of the risks of
                 investing in the Portfolios by showing changes in the
                 performance of each Portfolio's shares from year to year for
                 the life of each Portfolio and the highest and lowest quarterly
                 return during the life of each Portfolio.

                 The Portfolios' past performance does not necessarily indicate
                 how each Portfolio will perform in the future. The Portfolios'
                 performance does not reflect charges and deductions which are
                 imposed under the variable contracts.

*On September 16, 1994, an investment company then called Quest for Value
Accumulation Trust (the "Old Trust") was effectively divided into two investment
funds, the Old Trust and the Fund, at which time the Fund commenced operations.
The total net assets for each of the Equity, Small Cap and Managed Portfolios
immediately after the transaction were $86,789,755, $139,812,573 and
$682,601,380, respectively, with respect to the Old Trust and for each of the
Equity, Small Cap and Managed Portfolios, $3,764,598, $8,129,274 and
$51,345,102, respectively, with respect to the Fund. For the period prior to
September 16, 1994, the performance figures above for each of the Equity, Small
Cap and Managed Portfolios reflect the performance of the corresponding
Portfolios of the Old Trust. The Old Trust commenced operations on August 1,
1988.

The benchmark for the portion of the Managed Portfolio managed by PIMCO is the
Lehman Brothers Aggregate Bond Index.

                         PRINCIPAL INVESTMENT STRATEGIES

EQUITY PORTFOLIO

Q  What is the Portfolio's investment objective?

A  Long term capital appreciation through investment in a diversified portfolio
   of equity securities selected on the basis of a value approach to investing.

Q  What is the Portfolio's investment program?


                                       8
<PAGE>

A  The Equity Portfolio invests primarily in equity securities of companies that
   OpCap Advisors believes are undervalued in the marketplace. Under normal
   conditions, the Portfolio will invest at least 65% of its total assets in
   equity securities listed on the New York Stock Exchange. The Portfolio also
   may purchase securities listed on other U.S. or foreign securities exchanges
   or traded in the U.S. or foreign over the counter markets.

   The Equity Portfolio is managed to follow a composite portfolio constructed
   by a group of senior portfolio managers at OpCap Advisors.

Q  What are the potential rewards of investing in the Portfolio?

A  Common stocks and other equity securities offer a way to invest for long term
   growth of capital. Equity investors should have a long term investment
   horizon and should be prepared for the ups and downs of the stock markets.


MID CAP PORTFOLIO

Q  What is the Portfolio's investment objective?

A  Long term capital appreciation.

Q  What is the Portfolio's investment program?

A  The Portfolio invests primarily in equity securities of companies with market
   capitalizations between $500 million and $5 billion at the time of purchase
   which OpCap Advisors believes are undervalued. The majority of the stocks
   purchased by the Portfolio will be listed on a domestic stock exchange or
   traded in the U.S. over the counter market. The Portfolio may purchase
   foreign securities that are listed on a U.S. or foreign exchange or traded in
   the U.S. or foreign over the counter markets. The Portfolio also may purchase
   securities in initial public offerings or shortly after those offerings have
   been completed.

Q  What are the potential rewards of investing in the Portfolio?

A  Common stocks offer a way to invest for long term growth of capital. Mid cap
   companies generally are studied by fewer analysts than are large cap
   companies. Institutional investors may not want to hold large positions in
   mid cap companies. Opportunities for capital appreciation for mid cap
   companies could result from regional or product line expansion or sale of the
   company.

SMALL CAP PORTFOLIO

Q  What is the Portfolio's investment objective?

A  Capital appreciation through a diversified portfolio consisting primarily of
   securities of


                                       9
<PAGE>

   companies with market capitalizations of under $1 billion at time of
   purchase.

Q  What is the Portfolio's investment program?

A  The Portfolio invests primarily in equity securities of companies with market
   capitalizations under $1 billion at the time of purchase that OpCap Advisors
   believes are undervalued in the marketplace. The Portfolio may purchase
   securities listed on U.S. or foreign securities exchanges or traded in the
   U.S. or foreign over the counter markets. The Portfolio also may purchase
   securities in initial public offerings or shortly after those offerings have
   been completed.

Q  What are the potential rewards of investing in the Portfolio?

A  Common stocks offer a way to invest for long term growth of capital.
   Opportunities for value creation for small cap companies could result from
   product expansion or product improvement, industry transition, new management
   or sale of the company. Small cap companies are followed by fewer analysts
   than are large and mid cap companies. So as additional analysts follow a
   small cap stock, investor demand for the stock may increase.


MANAGED PORTFOLIO

Q  What is the Portfolio's investment objective?

A  Growth of capital over time through investment in a portfolio consisting of
   common stocks, bonds and cash equivalents, the percentages of which will vary
   based on OpCap Advisors' and PIMCO's assessments of the relative outlook for
   such investments.

Q  What is the Portfolio's investment program?

A  The Portfolio seeks to meet its objective by investing in common stocks,
   bonds and cash equivalents in varying percentages based on OpCap Advisors'
   and PIMCO's view of relative values. The Portfolio may purchase securities
   listed on U.S. or foreign securities exchanges or traded in the U.S. or
   foreign over the counter markets. The Portfolio also may purchase investment
   grade U.S. government and corporate bonds and high quality money market
   securities. The Portfolio can invest up to 100% of its assets in debt
   securities but will only do so if equity securities are not an attractive
   investment.

Q  What are the potential rewards of investing in the Portfolio?

A  The Portfolio normally invests mainly in equity securities. Common stocks
   offer a way to invest for long term growth of capital.

                                     RISKS

Q  What are the risks of investing in the Portfolios?

A  The Equity, Mid Cap, Small Cap and Managed Portfolios invest principally in
   equity securities which may be affected by the following:

   STOCK MARKET VOLATILITY - The stock market in general may fluctuate in
   response to political, market and economic developments and you can lose
   money on your investments.

   Equity investors should have a long-term investment horizon and should be
   prepared for the ups and downs of the stock market.

   STOCK PICKING - The portfolio manager may select stocks that have prices that
   turn out not to be undervalued or do not achieve expectations for growth in
   income or revenues.

   ISSUER CHANGES - Changes in the financial condition of an issuer or changes
   in economic conditions that affect a particular type of issuer can affect the
   value or credit quality of an issuer's securities.

   SMALL CAP AND MID CAP VOLATILITY - Mid cap stocks are more volatile and have
   less trading volume than large cap stocks. Small cap stocks are more volatile
   and have less trading volume than both large cap and mid cap stocks.

   SECTOR RISK - OpCap Advisors are bottom up investment managers. That means
   that they select securities for a Portfolio based on the investment merits of
   a particular issue rather than the business sector.

   INVESTMENT STYLES - Value or growth stocks may be out of favor for a period
   of time. Both investment styles can produce poor returns for a period of
   time.

   ASSET ALLOCATION RISK - The Managed Portfolio invest in a mix of equity and
   fixed income securities. The portfolio manager of the Managed Portfolio can
   make the wrong allocation decisions.

   FOREIGN EXPOSURE - When selecting foreign securities for the Portfolio, OpCap
   Advisors use approximately the same standards that they set for U.S. issuers.
   Foreign securities, foreign currencies and securities issued by U.S. entities
   with substantial foreign operations may have additional risks than U.S.
   securities.

      -  Political Risk - Foreign governments can take over the assets or
         operations of a company or may impose taxes or limits on the removal of
         the Portfolio's assets from that country.

      -  Currency risk - The value of securities held in foreign currencies will
         be affected by changes in the value of that currency.


                                       11
<PAGE>

      -  Liquidity - Some foreign markets are less liquid and more volatile than
         the U.S. stock market.

      -  Limited information - There may be less public information about
         foreign issuers than there is about U.S. issuers.

      -  Settlement and clearance - Some foreign markets experience delays in
         settlement. These delays could cause the Portfolio to miss investment
         opportunities or to be unable to sell a security.

      -  Euro - The effect of the Euro on international markets has not yet been
         determined.

      -  Emerging Markets - There are greater risks of unstable governments and
         economies and restriction on foreign ownership in these countries. The
         Portfolios presently intend to limit investment in emerging markets to
         no more than 5% of their total assets.

To the extent that the Portfolios invest in debt securities, the Portfolios are
exposed to these risks:

      -  Interest rate risk - The risk that changes in interest rates will
         affect the value of fixed income securities in the Portfolio.

      -  Prepayment risk - The risk that the holder of a mortgage underlying a
         mortgage backed security will prepay principal.

      -  Credit risk - The risk that an issuer of a fixed income security will
         be unable to pay principal and interest payments when they are due.


                               INVESTMENT POLICIES

Q  Can a Portfolio change its investment objective and investment policies?

A  Fundamental policies of a Portfolio cannot be changed without the approval of
   a majority of the outstanding voting shares of the Portfolio. A Portfolio's
   investment objective is a fundamental policy. Investment restrictions that
   are fundamental policies are listed in the Statement of Additional
   Information. Investment policies are not fundamental and can be changed by
   the Fund's Board of Trustees.

Q  Can the Portfolios use derivative instruments?

A  Yes. The Equity, Mid Cap, Small Cap and Managed Portfolios may use the
   following derivative instruments:


                                       12
<PAGE>

     -  futures contracts
     -  options on futures contracts
     -  forward foreign currency contracts
     -  covered calls written on individual securities
     -  uncovered calls and puts
     -  options on stock indices.

     The Equity, Mid Cap and Small Cap Portfolios do not expect to use
     derivative instruments significantly, if at all. The Managed Portfolio will
     sometimes use derivative instruments as part of a strategy designed to
     reduce exposure to other risks, such as interest risk or currency risk, and
     may use derivative instruments to meet their investment objectives.

Q  What are the risks of derivative instruments?

A  Derivative instruments can reduce the return of a Portfolio if :

     -  Its investment adviser uses a derivative instrument at the wrong time
     -  The prices of a Portfolio's futures or options positions are not
        correlated with its other investments
     -  A Portfolio cannot close out a position because of an illiquid market.

Q  Do the Portfolios expect to engage in short-term trading?

A  The Portfolios do not expect to engage in frequent short-term trading. The
   Financial Highlights table in this prospectus shows the turnover rates during
   prior fiscal years for the Portfolios that were active during this period.

Q  Can the Portfolios vary from their investment goals?

A  When a Portfolio's investment adviser or subadviser thinks market or economic
   conditions are adverse, it may invest up to 100% of its assets in defensive
   investments such as U.S. Government securities and money market instruments.
   To the extent that a Portfolio takes a defensive position, it will not be
   pursuing its investment objective.


                                 FUND MANAGEMENT

OPCAP ADVISORS

The Board of Trustees of the Fund has hired OpCap Advisors to serve as manager
of the Fund.

OpCap Advisors is a subsidiary of Oppenheimer Capital, an investment advisory
firm with approximately $53 billion of assets under management as of
December 31, 1999. They are indirect wholly-owned subsidiaries of PIMCO Advisors
L.P. The mailing address is 1345 Avenue of the Americas, New York, New
York 10105.


                                       13

The general partners of PIMCO Advisors L.P. are PIMCO Partners G.P. and PIMCO
Advisors Holding L.P. ("PAH"). PIMCO Partners, G.P. is a general partnership
between PIMCO Holdings LLC, a Delaware limited liability company and an indirect
wholly-owned subsidiary of Pacific Life Insurance Company, and PIMCO Partners
LLC, a California limited liability company controlled by the current Managing
Directors and two former Managing Directors of Pacific Investment Management
Company, a subsidiary of PIMCO Advisors L.P. PIMCO Partners, G.P. is the sole
general partner of PAH.

On October 31, 1999, PIMCO Advisors L.P., PAH and Allianz AG ("Allianz")
announced that they had reached a definitive agreement pursuant to which Allianz
will acquire majority ownership of PIMCO Advisors L.P. and its subsidiaries,
including OpCap Advisors (the "Allianz Transaction"). Under the terms of the
transaction, Allianz will acquire all of PAH, the publicly traded general
partner of PIMCO Advisors L.P. Pacific Life Insurance Company will retain an
approximately 30% interest in PIMCO Advisors L.P. The Allianz Transaction is
currently expected to be completed by on or about May 5, 2000.

Allianz is the world's second largest insurance company and a leading provider
of financial services, particularly in Europe, and is represented in 68
countries world-wide through subsidiaries, branch and representative offices,
and other affiliated entities. Allianz currently has assets under management of
more than $390 billion, and in its last fiscal year wrote approximately $50
billion in gross insurance premiums. After consummation of the transaction, the
combined firms will have over $650 billion in assets under management.

Affiliates of Allianz currently include Dresdner Bank AG, Deutsche Bank AG,
Munich Re, and Hypo Vereinsbank. These entities, as well as certain broker-
dealers controlled by or affiliated with these entities, such as Bankers Trust
Company and BT Alex Brown, Inc. are considered the "Affiliated Brokers." Once
the Allianz transaction is consummated, absent an SEC exemption or other relief,
the Fund's Portfolios would generally be precluded from effecting principal
transactions with the Affiliated Brokers, and each Portfolio's ability to
purchase securities being underwritten by an Affiliated Broker or to utilize the
Affiliated Brokers for agency transactions would be subject to restrictions.
OpCap Advisors does not believe that the restrictions on transactions with the
Affiliated Brokers described above will materially adversely affect its ability,
post-closing, to provide services to the Fund, the ability of the Portfolios to
take advantage of market opportunities, or the overall performance of the
Portfolios.

The consummation of the Allianz Transaction is subject to the approval of the
public unitholders of PAH, as well as to certain regulatory and client
approvals, and other conditions customary to transactions of this kind.

This Prospectus will be supplemented or revised if the Allianz Transaction does
not occur substantially as set forth above.

OpCap Advisors has been in business as an investment adviser since 1987 and
Oppenheimer Capital has been in business as an investment adviser since 1969.

OpCap Advisors manages the investments of certain Portfolios (and places
brokerage orders) and


                                       14
<PAGE>

conducts the business affairs of the Fund. Employees of Oppenheimer Capital,
PIMCO Advisors and OpCap Advisors perform these services.

Each Portfolio pays OpCap Advisors fees in return for providing or arranging for
the provision of investment advisory services. OpCap also pays a portion of its
advisory fees to PIMCO in return for the advisory services PIMCO performs for
the Managed Portfolio. The Portfolios of the Fund listed below paid OpCap
Advisors the following fees as a percentage of average daily net assets during
the fiscal year ended December 31, 1999:

<TABLE>
       <S>                                                        <C>
       Equity Portfolio...........................................0.80%
       Mid Cap Portfolio..........................................0.10%
       Small Cap Portfolio........................................0.80%
       Managed Portfolio..........................................0.77%
</TABLE>

OpCap will pay PIMCO a fee at the annual rate of 0.25% of the average daily net
assets of the Managed Portfolio for the advisory services PIMCO performed for
the Managed Portfolio.

OpCap Advisors waived a portion of its fees from the MidCap Portfolio for the
fiscal year ended December 31, 1999. Absent such waiver the advisory fee for the
MidCap Portfolio would have been 0.80% of the average daily net assets of the
Portfolio.

The Fund pays OpCap Advisors at the annual rate of .80% of the first $400
million of average net assets, .75% on the next $400 million of average net
assets and .70% of assets in excess of $800 million with respect to the Equity,
Managed, Small Cap and Mid Cap Portfolios.

                                   SHARE PRICE

The Fund calculates each Portfolio's share price, called its net asset value, on
each business day that the New York Stock Exchange is open after the close of
regular trading (generally 4:00 p.m. Eastern Standard Time). Net asset value per
share is computed by adding up the total value of a Portfolio's investments and
other assets, subtracting its liabilities and then dividing by the number of
shares outstanding.

                               TOTAL PORTFOLIO ASSETS - LIABILITIES
          Net Asset Value =  -------------------------------------------
                               NUMBER OF PORTFOLIO SHARES OUTSTANDING

The Fund uses the market prices of securities to value a Portfolio's investments
unless securities do not have market quotations or are short-term debt
securities. When the Fund uses fair value to price a security, the Fund reviews
the pricing method with the Fund's Board. The Fund prices short-term investments
that mature in less than 60 days using amortized cost or amortized value.
Foreign securities trade on days when the Portfolios do not price their shares
so the net asset value of a Portfolio's shares may change on days when
shareholders will not be able to buy or sell shares of the Portfolio. If an
event occurs after the close of the New York Stock Exchange that the Fund
believes changes the value of a security, then the Fund will value the security
at what it believes to be fair value.


                             DISTRIBUTIONS AND TAXES

This discussion is about distributions to the Portfolio's shareholders, which
are variable accounts of insurance companies and qualified pension and
retirement plans. You should read the prospectus for the variable account for
information about distributions and federal tax treatment for contract owners of
variable products.

Each Portfolio pays dividends from its net investment income and distributes any
net capital gains that it has realized at least once a year.


                              FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the
Portfolio's financial performance. Certain information reflects financial
results for a single Portfolio share. The total returns in the table represent
the rate that an investor would have earned (or lost) on an investment in a
Portfolio (assuming reinvestment of all dividends and distributions). The
information in the financial highlights table for the fiscal periods ended on
or before December 31, 1998 has been audited by PricewaterhouseCoopers LLP,
independent accountants, whose report, along with the corresponding
Portfolio's financial statements, is included in the Fund's SAI, which is
available upon request. The information in the financial highlights table for
the year ended on December 31, 1999, along with the corresponding Portfolios'
financial statements are audited. The interim financial statements are
included in the Fund's SAI.

INVESTMENT
PHILOSOPHY                          OpCap Advisors is the investment adviser to
                                    all of the Portfolios. OpCap Advisors has
                                    retained PIMCO Equity Advisors, a division
                                    of PIMCO Advisors L.P. ("PIMCO Equity
                                    Advisors"), as sub-adviser to the Large Cap

                                    of the Blended Equity Portfolio. OpCap
                                    Advisors has retained Pacific Investment
                                    Management Company ("PIMCO") as sub-adviser
                                    for a portion of the assets of the Managed

                                    investing, although the individual portfolio
                                    managers may implement those principles
                                    differently.

                                    When selecting equity securities, OpCap
                                    Advisors believes there are two major
                                    components of value.

                                    -   A company's ability to generate earnings
                                        that contribute to shareholder value.
                                        OpCap Advisors considers discretionary
                                        cash flow-cash that remains after a
                                        company spends what is needed to sustain
                                        its industrial position as a primary
                                        determinant of a company's potential to
                                        add economic value.

                                    -   Price - OpCap Advisors looks for market
                                        undervaluation great enough to offer the
                                        potential for upside reward with what it
                                        believes is modest downward risk.

                                    OpCap Advisors uses fundamental company
                                    analysis to select securities. Fundamental
                                    company analysis involves intensive
                                    evaluation of historic financial data
                                    including:

                                    -   Company financial statements
                                    -   Market share analysis
                                    -   Unit volume growth
                                    -   Barriers to entry
                                    -   Pricing policies
                                    -   Management record.

                                    OpCap Advisors uses fundamental company
                                    analysis to select companies they believe
                                    have one or more of the following
                                    characteristics:

                                    -   substantial and growing discretionary
                                        cash flow
                                    -   strong shareholder value-oriented
                                        management
                                    -   valuable consumer or commercial
                                        franchises
                                    -   high returns on capital
                                    -   favorable price to intrinsic value
                                        relationship.

                                    In selecting debt securities, OpCap Advisors
                                    analyzes yield relationships between
                                    different sectors and among securities along
                                    the yield curve. OpCap Advisors seeks to
                                    take advantage of maturities and individual
                                    issues that are inexpensive and have the
                                    potential to provide superior returns. In
                                    evaluating high yield debt securities, OpCap
                                    Advisors supplements its traditional credit
                                    analysis with an evaluation of an issuer's
                                    asset values.

                                    There can be no assurance that OpCap
                                    Advisors will achieve its goals.

                                    that it will achieve these goals.

                                    PIMCO acts as the sub-adviser to the Managed
                                    Portfolio. In selecting securities for the
                                    Managed Portfolio, PIMCO develops an outlook
                                    for interest rates, currency exchange rates
                                    and the economy; analyzes credit and call
                                    risks, and uses other security selection
                                    techniques. The proportion of the
                                    Portfolio's assets committed to investment
                                    in securities with particular
                                    characteristics (such as quality, section
                                    interest rate or maturity) varies based on
                                    PIMCO's outlook for the U.S. economy and the
                                    economies of other countries in the world,
                                    the financial markets and other factors.

                                    PIMCO attempts to identify areas of the bond
                                    market that are undervalued relative to the
                                    rest of the market. PIMCO identifies these
                                    areas by grouping bonds into the following
                                    sectors: money markets, governments,
                                    corporates, mortgages, asset-backed and
                                    international. Sophisticated proprietary
                                    software then assists in evaluating sectors
                                    and pricing specific securities. Once
                                    investment opportunities are identified,
                                    PIMCO will shift assets among sectors
                                    depending upon changes in relative
                                    valuations and credit spreads. There is no
                                    guarantee that PIMCO's security selection
                                    techniques will produce the desired results.

PRINCIPAL RISKS                     If you invest in the Portfolios that invest
                                    in equity securities, you could lose money
                                    or those Portfolios could underperform other
                                    investments if any of the following happens:

                                    -   The stock market goes down
                                    -   The Portfolio's investment style (i.e.,
                                        value or growth) falls out

                                    -   The Portfolio's investment sector (e.g.,
                                        small cap, mid cap or foreign
                                        securities, which generally are more
                                        volatile than U.S. large cap securities)
                                        declines or becomes less liquid

                                    -   For the Equity, Mid Cap, Small Cap,
                                        Global Equity, Managed and Balanced
                                        Portfolios, the market undervalues the
                                        stocks held for longer than expected, or
                                        the stocks purchased turn out not to be
                                        undervalued

                                    -   The stocks selected for growth potential
                                        do not achieve such growth.

                                    If you invest in the Portfolios that invest
                                    in debt securities, you could lose money or
                                    your investment may underperform other
                                    investments if any of the following happens:

                                    -   Interest rates rise and the bond market
                                        goes down
                                    -   Issuers of debt instruments cannot meet
                                        their obligations
                                    -   Bond issuers' call bonds selling at a
                                        premium to their call price before the
                                        maturity date
                                    -   Loans securing mortgage-backed
                                        obligations prepay principal more
                                        rapidly than expected. The Portfolios
                                        may have to reinvest these prepayments
                                        at lower rates.

                                    The U.S. Government Income Portfolio
                                    principally buys fixed income securities
                                    that are issued or guaranteed by the U.S.

                                    instrumentalities, so credit risk should be

BAR CHART &
PERFORMANCE
TABLE
                     The bar charts provide some indication of the risks of
                     investing in the Portfolios by showing changes in the
                     performance of each Portfolio's shares from year to year
                     for the life of each Portfolio and the highest and lowest
                     quarterly return during the life of each Portfolio.
                     Performance is not shown in a table for the Blended Equity,
                     Balanced, Large Cap Growth, Small Cap Growth and Target
                     Portfolios because they do not have a full calendar year of
                     performance.

                     The Portfolios' past performance does not necessarily
                     indicate how each Portfolio will perform in the future. The
                     Portfolios' performance does not reflect charges and
                     deductions which are imposed under the variable contracts.

*On September 16, 1994, an investment company then called Quest for Value
Accumulation Trust (the "Old Trust") was effectively divided into two investment
funds, the Old Trust and the Fund, at which time the Fund commenced operations.
The total net assets for each of the Equity, Small Cap and Managed Portfolios
immediately after the transaction were $86,789,755, $139,812,573 and

                         PRINCIPAL INVESTMENT STRATEGIES

EQUITY PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Long term capital appreciation through investment in a diversified
     portfolio of equity securities selected on the basis of a value approach to
     investing.

Q    What is the Portfolio's investment program?

A    The Equity Portfolio invests primarily in equity securities of companies
     that OpCap Advisors believes are undervalued in the marketplace. Under
     normal conditions, the Portfolio will invest at least 65% of its total
     assets in equity securities listed on the New York Stock Exchange. The
     Portfolio also may purchase securities listed on other U.S. or foreign
     securities exchanges or traded in the U.S. or foreign over the counter
     markets.

     The Equity Portfolio is managed to follow a composite portfolio constructed
     by a group of senior portfolio managers at OpCap Advisors.

Q    What are the potential rewards of investing in the Portfolio?

A    Common stocks and other equity securities offer a way to invest for long
     term growth of capital. Equity investors should have a long term investment
     horizon and should be prepared for the ups and downs of the stock markets.


BLENDED EQUITY PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Long term capital appreciation.

Q    What is the Portfolio's investment program?

A    The Portfolio invests generally in equity securities of companies with
     market capitalization of a least $5 billion at the time of purchase that
     PIMCO Equity Advisors believes will experience relatively rapid earnings
     growth and in equity securities of companies with market capitalizations of
     at least $2 billion that OpCap Advisors believes are undervalued relative
     to their industry group. The majority of the stocks purchased by the
     Portfolio will be listed on a domestic stock exchange or traded in the U.S.
     over the counter market. The Portfolio may purchase foreign securities that
     are listed on a U.S. or foreign exchange or traded in the U.S. or foreign
     over the counter market, purchase and sell foreign currencies and use
     derivatives for risk management purposes or as part of its investment
     strategy. In response to unfavorable market and other conditions, the
     Portfolio may invest temporarily in


                                       12
<PAGE>

     high-quality fixed income securities.

Q    What are the potential rewards of investing in the Portfolio?

A    Common stocks and other equity securities offer a way to invest for long
     term growth of capital. Opportunities for long term growth of capital arise
     from companies that are undervalued relative to their industry group or
     show strong potential for growth or experience better than anticipated
     earnings growth.


LARGE CAP GROWTH PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Long term capital appreciation.

Q    What is the Portfolio's investment program?

A    The Portfolio invests primarily in equity securities of companies with
     market capitalizations of at least $5 billion at the time of purchase which
     PIMCO Equity Advisors believes will experience relatively rapid earnings
     growth. The majority of the stocks purchased by the Portfolio will be
     listed on a domestic stock exchange or traded in the U.S. over the counter
     market. The Portfolio may purchase foreign securities that are listed on a
     U.S. or foreign exchange or traded in the U.S. or foreign over the counter
     market, purchase and sell foreign currencies and use derivatives for risk
     management purposes or as part of its investment strategy. In response to
     unfavorable market and other conditions, the Portfolio may invest
     temporarily in high-quality fixed income securities.

Q    What are the potential rewards of investing in the Portfolio?

A    Common stocks and other equity securities offer a way to invest for long
     term growth of capital. The prices of securities of large cap companies may
     be less volatile than those of less highly-capitalized companies.


SMALL CAP GROWTH PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Capital appreciation.

Q    What is the Portfolio's investment program?

A    The Portfolio invests primarily in equity securities of companies with
     market capitalizations of under $2 billion at the time of purchase which
     PIMCO Equity Advisors believes will experience relatively rapid earnings
     growth. The majority of the stocks purchased by the


                                       13
<PAGE>

     Portfolio will be listed on a domestic stock exchange or traded in the U.S.
     over the counter market. The Portfolio may purchase foreign securities that
     are listed on a U.S. or foreign exchange or traded in the U.S. or foreign
     over the counter market, purchase and sell foreign currencies and use
     derivatives for risk management purposes or as part of its investment
     strategy. In response to unfavorable market and other conditions, the
     Portfolio may invest temporarily in high-quality fixed income securities.

Q    What are the potential rewards of investing in the Portfolio?

A    Common stocks and other equity securities offer a way to invest for long
     term growth of capital. Opportunities for appreciation for small cap
     companies could result from product expansion or product improvement,
     industry transition, new management or the sale of the company. Small cap
     companies are followed by fewer analysts than are large and mid cap
     companies. So as additional analysts follow a small cap stock, investor
     demand for the stock may increase.

TARGET PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Capital appreciation.

Q    What is the Portfolio's investment program?

A    The Portfolio invests primarily in equity securities of companies with
     market capitalizations between $1 billion and $10 billion at the time of
     purchase which PIMCO Equity Advisors believes will experience relatively
     rapid earnings growth. The majority of the stocks purchased by the
     Portfolio will be listed on a domestic stock exchange or traded in the U.S.
     over the counter market. The Portfolio may purchase foreign securities that
     are listed on a U.S. or foreign exchange or traded in the U.S. or foreign
     over the counter market, purchase and sell foreign currencies and use
     derivatives for risk management purposes or as part of its investment
     strategy. In response to unfavorable market and other conditions, the
     Portfolio may invest temporarily in high-quality fixed income securities.

Q    What are the potential rewards of investing in the Portfolio?

A    Common stocks offer a way to invest for long term growth of capital. To the
     extent the Portfolio invests in mid cap companies it may take advantage of
     opportunities for value creation resulting from regional or product line
     expansion or the sale of such companies. Investments in larger-size
     companies help mitigate the volatility of the Portfolio.


MID CAP PORTFOLIO

Q    What is the Portfolio's investment objective?


                                       14
<PAGE>

A    Long term capital appreciation.

Q    What is the Portfolio's investment program?

A    The Portfolio invests primarily in equity securities of companies with
     market capitalizations between $500 million and $5 billion at the time of
     purchase which OpCap Advisors believes are undervalued. The majority of the
     stocks purchased by the Portfolio will be listed on a domestic stock
     exchange or traded in the U.S. over the counter market. The Portfolio may
     purchase foreign securities that are listed on a U.S. or foreign exchange
     or traded in the U.S. or foreign over the counter markets. The Portfolio
     also may purchase securities in initial public offerings or shortly after
     those offerings have been completed.

Q    What are the potential rewards of investing in the Portfolio?

A    Common stocks offer a way to invest for long term growth of capital. Mid
     cap companies generally are studied by fewer analysts than are large cap
     companies. Institutional investors may not want to hold large positions in
     mid cap companies. Opportunities for capital appreciation for mid cap
     companies could result from regional or product line expansion or sale of
     the company.

SMALL CAP PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Capital appreciation through a diversified portfolio consisting primarily
     of securities of companies with market capitalizations of under $1 billion
     at time of purchase.

Q    What is the Portfolio's investment program?

A    The Portfolio invests primarily in equity securities of companies with
     market capitalizations under $1 billion at the time of purchase that OpCap
     Advisors believes are undervalued in the marketplace. The Portfolio may
     purchase securities listed on U.S. or foreign securities exchanges or
     traded in the U.S. or foreign over the counter markets. The Portfolio also
     may purchase securities in initial public offerings or shortly after those
     offerings have been completed.

Q    What are the potential rewards of investing in the Portfolio?

A    Common stocks offer a way to invest for long term growth of capital.
     Opportunities for value creation for small cap companies could result from
     product expansion or product improvement, industry transition, new
     management or sale of the company. Small cap companies are followed by
     fewer analysts than are large and mid cap companies. So as additional
     analysts follow a small cap stock, investor demand for the stock may
     increase.

GLOBAL EQUITY PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Long term capital appreciation through pursuit of a global investment
     strategy primarily involving equity securities.

Q    What is the Portfolio's investment program?

A    The Portfolio invests primarily in equity securities of companies located
     throughout the world which OpCap Advisors believes are undervalued in the
     marketplace. The Portfolio may invest up to 35% of its total assets in
     fixed income securities which may be lower than investment grade.

Q    What are the potential rewards of investing in the Portfolio?

A    Foreign securities provide additional opportunities and diversification.
     U.S. stocks represent less than half of the world's stock market
     capitalization.


MANAGED PORTFOLIO

Q    What is the Portfolio's investment objective?

A    Growth of capital over time through investment in a portfolio consisting of
     common stocks, bonds and cash equivalents, the percentages of which will
     vary based on OpCap Advisors' and PIMCO's assessments of the relative
     outlook for such investments.

Q    What is the Portfolio's investment program?

A    The Portfolio seeks to meet its objective by investing in common stocks,
     bonds and cash equivalents in varying percentages based on OpCap Advisors'
     and PIMCO's view of relative values. The Portfolio may purchase securities
     listed on U.S. or foreign securities exchanges or traded in the U.S. or
     foreign over the counter markets. The Portfolio also may purchase
     investment grade U.S. government and corporate bonds and high quality money
     market securities. The Portfolio can invest up to 100% of its assets in
     debt securities but will only do so if equity securities are not an
     attractive investment.

Q    What are the potential rewards of investing in the Portfolio?

A    The Portfolio normally invests mainly in equity securities. Common stocks
     offer a way to invest for long term growth of capital.


BALANCED PORTFOLIO


                                       16
<PAGE>

Q    What is the Portfolio's investment objective?

A    Growth of capital and investment income.

Q    What is the Portfolio's investment program?

A    The Portfolio invests in equity securities (with an emphasis on
     dividend-paying stocks) and debt securities that OpCap Advisors believes
     are undervalued. Generally, the Portfolio will invest at least 25% of its
     total assets in equity securities and at least 25% of its total assets in
     debt securities. The Portfolio seeks debt securities that offer investment
     income and the potential for capital appreciation if interest rates decline
     or the issuer's credit improves. OpCap Advisors seek to find convertible
     securities that have the potential for investment income prior to
     conversion and capital growth. Convertible debt securities may be
     classified as equity securities or as debt securities depending on the
     value of the conversion feature as compared to the debt feature. The
     Portfolio may purchase securities listed on U.S. or foreign securities
     exchanges or traded in U.S. or foreign over the counter markets. The
     Portfolio may invest up to 25% of its total assets in debt securities rated
     below investment grade.

Q    What are the potential rewards of investing in the Portfolio?

A    The Portfolio's mix of equity securities, convertible securities and debt
     securities may result in the Portfolio's being less volatile than the
     market.


U.S. GOVERNMENT INCOME PORTFOLIO

Q    What is the Portfolio's investment objective?

A   High level of current income together with protection of capital by
    investing exclusively in debt obligations, including mortgage-backed
    securities issued or guaranteed by the United States government, its
    agencies or instrumentalities.

Q    What is the Portfolio's investment program?

A   The Portfolio invests in debt obligations issued or guaranteed by the United
    States Government, its agencies or instrumentalities. These securities are
    referred to as "U.S. Government Securities." The Portfolio also may purchase
    mortgage-backed securities to effectuate this program.

    OpCap Advisors observes current and historical yield relationships between
    maturities and sectors to seek the best relative values. The Portfolio
    generally maintains an average maturity between five and ten years. OpCap
    Advisors does not attempt to forecast interest rates in managing the
    Portfolio.

Q    What are the potential rewards of investing in the Portfolio?


                                       17
<PAGE>

A   The Portfolio consists of the highest quality debt instruments. Since the
    average maturity of the Portfolio's investments are between five and ten
    years, the Portfolio should be less volatile than a longer term bond fund.

                                      RISKS

Q    What are the risks of investing in the Portfolios?

A    The Equity, Blended Equity, Large Cap Growth, Small Cap Growth, Target, Mid
     Cap, Small Cap, Global Equity, Managed and Balanced Portfolios invest
     principally in equity securities which may be affected by the following:

     STOCK MARKET VOLATILITY - The stock market in general may fluctuate in
     response to political, market and economic developments and you can lose
     money on your investments.

     Equity investors should have a long-term investment horizon and should be
     prepared for the ups and downs of the stock market.

     STOCK PICKING - The portfolio manager may select stocks that have prices
     that turn out not to be undervalued or do not achieve expectations for
     growth in income or revenues.

     ISSUER CHANGES - Changes in the financial condition of an issuer or changes
     in economic conditions that affect a particular type of issuer can affect
     the value or credit quality of an issuer's securities.

     SMALL CAP AND MID CAP VOLATILITY - Mid cap stocks are more volatile and
     have less trading volume than large cap stocks. Small cap stocks are more
     volatile and have less trading volume than both large cap and mid cap
     stocks.

     SECTOR RISK - OpCap Advisors are bottom up investment managers. That means
     that they select securities for a Portfolio based on the investment merits
     of a particular issue rather than the business sector.

     INVESTMENT STYLES - Value or growth stocks may be out of favor for a period
     of time. Both investment styles can produce poor returns for a period of
     time.

     ASSET ALLOCATION RISK - The Managed and Balanced Portfolios invest in a mix
     of equity and fixed income securities. The portfolio managers of those
     Portfolios can make the wrong allocation decisions.

     FOREIGN EXPOSURE - When selecting foreign securities for the Portfolios,
     OpCap Advisors use approximately the same standards that they set for U.S.
     issuers. Foreign securities, foreign currencies and securities issued by
     U.S. entities with substantial foreign operations may have additional risks
     than U.S. securities. This risk is greater for the Global Equity Portfolio
     which invests on a worldwide basis.


                                       18
<PAGE>

     -    Political Risk - Foreign governments can take over the assets or
          operations of a company or may impose taxes or limits on the removal
          of the Portfolio's assets from that country.

     -    Currency risk - The value of securities held in foreign currencies
          will be affected by changes in the value of that currency.

     -    Liquidity - Some foreign markets are less liquid and more volatile
          than the U.S. stock market.

     -    Limited information - There may be less public information about
          foreign issuers than there is about U.S. issuers.

     -    Settlement and clearance - Some foreign markets experience delays in
          settlement. These delays could cause the Portfolio to miss investment
          opportunities or to be unable to sell a security.

     -    Euro - The effect of the Euro on international markets has not yet
          been determined.

     -    Emerging Markets - There are greater risks of unstable governments and
          economies and restriction on foreign ownership in these countries. The
          Portfolios presently intend to limit investment in emerging markets to
          no more than 5% of their total assets.

To the extent that the Portfolios invest in debt securities, the Portfolios are
exposed to these risks:

     -    Interest rate risk - The risk that changes in interest rates will
          affect the value of fixed income securities in the Portfolio.

     -    Prepayment risk - The risk that the holder of a mortgage underlying a
          mortgage backed security will prepay principal.

     -    Credit risk - The risk that an issuer of a fixed income security will
          be unable to pay principal and interest payments when they are due.

To the extent that the Global Equity Portfolio or the Balanced Portfolio invests
in lower grade debt securities, you should know that lower grade debt may have
the following additional risks:

         -    more volatility

         -    less liquidity

         -    greater risk of issuer default or insolvency.

                               INVESTMENT POLICIES

Q    Can a Portfolio change its investment objective and investment policies?

A   Fundamental policies of a Portfolio cannot be changed without the approval
    of a majority of the outstanding voting shares of the Portfolio. A
    Portfolio's investment objective is a fundamental policy. Investment
    restrictions that are fundamental policies are listed in the Statement of
    Additional Information. Investment policies are not fundamental and can be
    changed by the Fund's Board of Trustees.

Q    Can the Portfolios use derivative instruments?

A    Yes. The Equity, Blended Equity, Large Cap Growth, Small Cap Growth,
     Target, Mid Cap, Small Cap, Global Equity, Managed and Balanced Portfolios
     may use the following derivative instruments:

     -   futures contracts
     -   options on futures contracts
     -   forward foreign currency contracts
     -   covered calls written on individual securities
     -   uncovered calls and puts
     -   options on stock indices.

     The Equity, Mid Cap, Small Cap, Global Equity and Balanced Portfolios do
     not expect to use derivative instruments significantly, if at all. The
     Blended Equity, Managed, Large Cap Growth, Small Cap Growth and Target
     Portfolios will sometimes use derivative instruments as part of a strategy
     designed to reduce exposure to other risks, such as interest risk or
     currency risk, and may use derivative instruments to meet their investment
     objectives.

Q    What are the risks of derivative instruments?

A    Derivative instruments can reduce the return of a Portfolio if :

     -   Its investment adviser uses a derivative instrument at the wrong time
     -   The prices of a Portfolio's futures or options positions are not
         correlated with its other investments
     -   A Portfolio cannot close out a position because of an illiquid market.

Q    Do the Portfolios expect to engage in short-term trading?

A    The Portfolios do not expect to engage in frequent short-term trading. The
     Financial Highlights table in this prospectus shows the turnover rates
     during prior fiscal years for the Portfolios that were active during this
     period.


                                       20
<PAGE>

Q    Can the Portfolios vary from their investment goals?

A    When a Portfolio's investment adviser or subadviser thinks market or
     economic conditions are adverse, it may invest up to 100% of its assets in
     defensive investments such as U.S. Government securities and money market
     instruments. To the extent that a Portfolio takes a defensive position, it
     will not be pursuing its investment objective.

                                 FUND MANAGEMENT

OPCAP ADVISORS

The Board of Trustees of the Fund has hired OpCap Advisors to serve as manager
of the Fund.

and other affiliated entities. Allianz currently has assets under management of
more than $390 billion, and in its last fiscal year wrote approximately $50
billion in gross insurance premiums. After consummation of the transaction, the
combined firms will have over $650 billion in assets under management.

Affiliates of Allianz currently include Dresdner Bank AG, Deutsche Bank AG,
Munich Re, and Hypo Vereinsbank. These entities, as well as certain broker-
dealers controlled by or affiliated with these entities, such as Bankers Trust
Company and BT Alex Brown, Inc. are considered the "Affiliated Brokers". Once
the Allianz transaction is consummated, absent an SEC exemption or

other relief, the Fund's Portfolios would generally be precluded from effecting
principal transactions with the Affiliated Brokers, and each Portfolio's ability
to purchase securities being underwritten by an Affiliated Broker or to utilize
the Affiliated Brokers for agency transactions would be subject to restrictions.
OpCap Advisors does not believe that the restrictions on transactions with the
Affiliated Brokers described above will materially adversely affect its ability,
post-closing, to provide services to the Fund, the ability of the Portfolios to
take advantage of market opportunities, or the overall performance of the
Portfolios.

The consummation of the Allianz Transaction is subject to the approval of the
public unitholders of PAH, as well as to certain regulatory and client
approvals, and other conditions customary to transactions of this kind.

This Prospectus will be supplemented or revised if the Allianz Transaction does
not occur substantially as set forth above.

OpCap Advisors has been in business as an investment adviser since 1987 and
Oppenheimer Capital has been in business as an investment adviser since 1969.

OpCap Advisors manages the investments of certain Portfolios (and places
brokerage orders) and conducts the business affairs of the Fund. Employees of
Oppenheimer Capital, PIMCO Advisors and OpCap Advisors perform these services.

Each Portfolio pays OpCap Advisors fees in return for providing or arranging for
the provision of investment advisory services. In the case of the Blended
Equity, Large Cap Growth, Small Cap Growth and Target Portfolios for which OpCap
Advisors has retained PIMCO Equity Advisors as subadvisor, OpCap Advisors (and
not the Fund) pays a portion of the advisory fees its receives to PIMCO Equity
Advisors in return for its services. OpCap also pays a portion of its advisory
fees to PIMCO in return for the advisory services PIMCO performs for the Managed
Portfolio. The Portfolios of the Fund listed below paid OpCap Advisors the
following fees as a percentage of average daily net assets during the fiscal
year ended December 31, 1999:

<TABLE>
     <S>                                                            <C>
     Equity Portfolio...............................................0.80%
     Mid Cap Portfolio..............................................0.10%
     Small Cap Portfolio............................................0.80%
     Global Equity Portfolio........................................0.80%
     Managed Portfolio..............................................0.77%
     U.S. Government Income Portfolio...............................0.60%
</TABLE>

OpCap will pay PIMCO a fee at the annual rate of 0.25% of the average daily net
assets of the Managed Portfolio for the advisory services PIMCO performed for
the Managed Portfolio.

OpCap Advisors waived a portion of its fees from the MidCap Portfolio for the
fiscal year ended December 31, 1999. Absent such waiver the advisory fee for the
MidCap Portfolio would have been 0.80% of the average daily net assets of the
Portfolio.


                                       22

million of average net assets, .75% on the next $400 million of average net
assets and .70% of assets in excess of $800 million with respect to the Equity,
Global Equity, Managed, Small Cap, Mid Cap, Balanced, Blended Equity, Large Cap
Growth, Small Cap Growth and Target Portfolios. The rate applicable to the U.S.
Government Income Portfolio is .60% of average net assets.

the first $400 million of average net assets, .375% on the next $400 million of

                                   SHARE PRICE

The Fund calculates each Portfolio's share price, called its net asset value, on
each business day that the New York Stock Exchange is open after the close of
regular trading (generally 4:00 p.m. Eastern Standard Time). Net asset value per
share is computed by adding up the total value of a Portfolio's investments and
other assets, subtracting its liabilities and then dividing by the number of
shares outstanding.

                            TOTAL PORTFOLIO ASSETS - LIABILITIES
       Net Asset Value =  ---------------------------------------
                            NUMBER OF PORTFOLIO SHARES OUTSTANDING

The Fund uses the market prices of securities to value a Portfolio's investments
unless securities do not have market quotations or are short-term debt
securities. When the Fund uses fair value to price a security, the Fund reviews
the pricing method with the Fund's Board. The Fund prices short-term investments
that mature in less than 60 days using amortized cost or amortized value.
Foreign securities trade on days when the Portfolios do not price their shares
so the net asset value of a Portfolio's shares may change on days when
shareholders will not be able to buy or sell shares of the Portfolio. If an
event occurs after the close of the New York Stock Exchange that the Fund
believes changes the value of a security, then the Fund will value the security
at what it believes to be fair value.

                             DISTRIBUTIONS AND TAXES

This discussion is about distributions to the Portfolio's shareholders, which
are variable accounts of insurance companies and qualified pension and
retirement plans. You should read the prospectus for the variable account for
information about distributions and federal tax treatment for contract owners of
variable products.

Each Portfolio pays dividends from its net investment income and distributes any
net capital gains that it has realized at least once a year. The U.S. Government
Income Portfolio pays dividends from its net investment income once a month.

                              FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the
Portfolios' financial performance. Certain information reflects financial
results for a single Portfolio share. The total returns in the table represent
the rate that an investor would have earned (or lost) on an investment in a
Portfolio (assuming reinvestment of all dividends and distributions). The
information in the financial highlights table below has been audited by
PricewaterhouseCoopers LLP, independent accountants, whose report, along with
the corresponding Portfolios' financial statements, is incorporated by reference
in the Fund's SAI, which is available upon request.
