          THIS STATEMENT OF ADDITIONAL INFORMATION IS NOT A PROSPECTUS
                AND IS AUTHORIZED FOR DISTRIBUTION TO PROSPECTIVE
            INVESTORS ONLY IF PRECEDED OR ACCOMPANIED BY AN EFFECTIVE
                                   PROSPECTUS.


                                       1

1. INVESTMENT POLICIES AND RESTRICTIONS

         The Prospectus identifies the investment objectives and the principal
investment policies of the Fund. Additional investment policies and a further
description of some of the policies described in the Prospectus appear below.
Capitalized terms not otherwise defined herein have the meaning given to them in
the Prospectus.

         The following policies and restrictions supplement those discussed in
the Prospectus. Whenever an investment policy or restriction states a maximum
percentage of the Fund's assets that may be invested in any security or presents
a policy regarding quality standards, this standard or other restrictions shall
be determined immediately after and as a result of the Fund's investment.
Accordingly, any later increase or decrease resulting from a change in values,
net assets or other circumstances will not be considered in determining whether
the investment complies with the Fund's investment objectives and policies.

LENDING OF PORTFOLIO SECURITIES

         In order to realize additional income, the Fund may lend its portfolio
securities, principally to broker-dealers, under agreements which would require
that the loans be secured continuously by cash equivalents or U.S. Treasury
bills equal at all times to at least the market value of the securities loaned.
The Fund would continue to receive the equivalent of the interest or dividends
paid by the issuer on the securities loaned as well as the benefit of an
increase and the detriment of any decrease in the market value of the securities
loaned and would also receive compensation based on investment of the loan
collateral. The loan collateral would be invested only in U.S. Treasury notes,
certificates of deposit or other high-grade, short-term obligations or
interest-bearing cash equivalents. The Fund would not, however, have the right
to vote any securities having voting rights during the existence of the loan,
but would call the loan in anticipation of an important vote to be taken among
holders of the securities or of the giving or withholding of consent on a
material matter affecting the investment.

         As with other extensions of credit, there are risks of delay in
recovery or even loss of rights in the collateral should the borrower of the
securities fail financially. The Fund will lend portfolio securities only to
firms which have been approved in advance by the Board of Trustees, which will
monitor the creditworthiness of any such firms. If the management of the Fund
decides to make securities loans, it is intended that the value of the
securities loaned by the Fund would not exceed 30% of the value of the Fund's
total assets. In the Fund's last fiscal year, the Fund did not lend portfolio
securities and, while it reserves the right to lend portfolio securities having
a value exceeding 5% of its net assets, the Fund has no present intention of
lending portfolio securities with such a value during the coming year.

COVERED CALL OPTIONS

         The Fund may write (sell) covered call options on certain portfolio
securities, but options may not be written on more than 25% of the aggregate
market value of any single portfolio security (determined each time a call is
sold as of the date of such sale). As a writer of a call option, the Fund
receives a premium less commission and, in exchange, foregoes the opportunity to
profit from increases in the market value of the security covering the call
above the sum of the premium and the exercise price of the option during the
life of the option. The purchaser of such a call has the option of purchasing
the security from the Fund's portfolio at the option price during the life of
the option. Portfolio securities on which options may be written are purchased
solely on the basis of investment considerations consistent with the Fund's
investment objectives. The security covering the call is maintained in a
segregated account of the


                                       2


<PAGE>


Fund's custodian. The Fund does not consider a security covered by a call
option to be "pledged" as that term is used in the Fund's policy which limits
the pledging or mortgaging of its assets.

         The Fund will purchase a call option only when entering into a "closing
purchase transaction," i.e., a purchase of a call option on the same security
with the same exercise price and expiration date as a "covered" call already
written by the Fund. There is no assurance that the Fund will be able to effect
such closing purchase transactions at a favorable price; if the Fund cannot
enter into such a transaction it may be required to hold a security that it
might otherwise have sold. The Fund's portfolio turnover may increase through
the exercise of options if the market price of the underlying securities
appreciates and the Fund has not entered into a closing purchase transaction.
The commission on the purchase or sale of a call option is higher in relation to
the premium than the commission in relation to the price on purchase or sale of
the underlying security.

WARRANTS

         The Fund may invest in warrants, which are securities permitting, but
not obligating, their holder to subscribe for other securities. Warrants do not
carry with them the right to dividends or voting rights with respect to the
securities that they entitle their holders to purchase, and they do not
represent any rights in the assets of the issuer. As a result, an investment in
warrants may be considered more speculative than certain other types of
investments. In addition, the value of a warrant does not necessarily change
with the value of the underlying securities and a warrant expires worthless if
it is not exercised on or prior to its expiration date. Although the Fund does
not have a formal percentage limitation on such investments, it is not expected
that PMC will invest more than 5% of the Fund's net assets in such securities.

FOREIGN SECURITIES

         The Fund may invest a portion of its assets in foreign securities.
Investing in securities of foreign companies and countries involves certain
considerations and risks that are not typically associated with investment in
U.S. government securities and securities of U.S. companies. Foreign companies
are not generally subject to uniform accounting, auditing and financial
standards and requirements comparable to those applicable to U.S. companies.
There may also be less publicly available information about foreign companies
compared to reports and ratings published about U.S. companies. In addition,
foreign securities markets have substantially less volume than U.S. markets and
securities of some foreign companies are less liquid and more volatile than
securities of comparable U.S. companies. There may also be less government
supervision and regulation of foreign securities exchanges, brokers and listed
companies than exists in the U.S. Dividends or interest, or in some cases
capital gains, from foreign investments may be subject to withholding or other
foreign taxes which will decrease the net return on such investments as compared
with the return on the Fund's U.S. investments. Finally, there may be the
possibility of expropriations, confiscatory taxation, political, economic or
social instability or diplomatic developments which could adversely affect
assets of the Fund held in foreign countries.

         The value of foreign securities may be adversely affected by
fluctuations in the relative rates of exchange between the currencies of
different nations and by exchange control regulations. For example, the value of
a foreign security held by the Fund as measured in U.S. dollars will decrease if
the foreign currency in which the security is denominated declines in value
against the U.S. dollar. In such event, this will cause an overall decline in
the Fund's net asset value and may also reduce net investment income and capital
gains, if any, to be distributed in U.S. dollars to shareholders of the Fund. In
connection with its


                                       3


<PAGE>


investments in foreign securities and in order to protect against
uncertainty in future exchange rates, the Fund may engage in foreign currency
exchange transactions.

DEBT SECURITIES

         No more than 5% of the Fund's net assets may be invested in debt
securities, including convertible securities, rated below "BBB" by Standard &
Poor's Ratings Group ("Standard & Poor's") or the equivalent. If the rating of a
debt security is reduced below investment grade ("BBB" or higher), management
will consider whatever action is appropriate, consistent with the Fund's
investment objectives and policies.

         Bonds rated below "BBB" or comparable unrated securities are commonly
referred to as "junk bonds" and are considered speculative and may be
questionable as to principal and interest payments. In some cases, such bonds
may be highly speculative, have poor prospects for reaching investment grade
standing and be in default. As a result, investment in such bonds will entail
greater speculative risks than those associated with investment in investment
grade bonds (i.e., bonds rated "BBB" or better by Standard & Poor's or, if
unrated by such rating organization, determined to be of comparable quality by
the Fund's investment adviser).

         The amount of junk bond securities outstanding has proliferated in
conjunction with the increase in merger and acquisition and leveraged buyout
activity. An economic downturn could severely affect the ability of highly
leveraged issuers to service their debt obligations or to repay their
obligations upon maturity. Factors having an adverse impact on the market value
of lower quality securities will have an adverse effect on the Fund's net asset
value to the extent that it invests in such securities. In addition, the Fund
may incur additional expenses to the extent it is required to seek recovery upon
a default in payment of principal or interest on its portfolio holdings.

         The secondary market for junk bond securities, which is concentrated in
relatively few market makers, may not be as liquid as the secondary market for
more highly rated securities, a factor which may have an adverse effect on the
Fund's ability to dispose of a particular security when necessary to meet its
liquidity needs. Under adverse market or economic conditions, the secondary
market for junk bond securities could contract further, independent of any
specific adverse changes in the condition of a particular issuer. As a result,
the Fund could find it more difficult to sell these securities or may be able to
sell the securities only at prices lower than if such securities were widely
traded. Prices realized upon the sale of such lower rated or unrated securities,
under these circumstances, may be less than the prices used in calculating the
Fund's net asset value.

         Certain proposed and recently enacted federal laws including the
required divestiture by federally insured savings and loan associations of their
investments in junk bonds and proposals designed to limit the use, or tax and
other advantages, of junk bond securities could adversely affect the Fund's net
asset value and investment practices. Such proposals could also adversely affect
the secondary market for junk bond securities, the financial condition of
issuers of these securities and the value of outstanding junk bond securities.
The form of such proposed legislation and the possibility of such legislation
being passed are uncertain.

         Since investors generally perceive that there are greater risks
associated with the medium to lower quality debt securities of the type in which
the Fund may invest a portion of its assets, the yields and prices of such
securities may tend to fluctuate more than those for higher rated securities. In
the lower quality segments of the debt securities market, changes in perceptions
of issuers' creditworthiness tend to


                                       4


<PAGE>


occur more frequently and in a more pronounced manner than do changes in
higher quality segments of the debt securities market, resulting in greater
yield and price volatility.

         Medium to lower rated and comparable unrated debt securities tend to
offer higher yields than higher rated securities with the same maturities
because the historical financial condition of the issuers of such securities may
not have been as strong as that of other issuers. Since medium to lower rated
securities generally involve greater risks of loss of income and principal than
higher rated securities, investors should consider carefully the relative risks
associated with investment in securities which carry medium to lower ratings and
in comparable unrated securities. The Fund's investment adviser will attempt to
reduce these risks through portfolio diversification and by analysis of each
issuer and its ability to make timely payments of income and principal, as well
as broad economic trends and corporate developments.

         The prices of all debt securities generally fluctuate in response to
the general level of interest rates. Another factor which causes fluctuations in
the prices of debt securities is the supply and demand for similarly rated
securities. Fluctuations in the prices of portfolio securities subsequent to
their acquisition will not affect any cash income from such securities but will
be reflected in the Fund's net asset value.
   
RESTRICTED AND ILLIQUID SECURITIES

     Restricted securities are securities which cannot be resold or distributed
to the public without an effective registration under the Securities Act of
1933, as amended (the "1933 Act"). Illiquid securities are securities which at
the time of investment are not readily marketable. For the purposes of this
Statement of Additional Information, restricted securities exclude any
restricted securities that have been determined by the Trustees (or their
designee) to be readily marketable such as restricted securities eligible for
resale to certain institutional investors pursuant to Rule 144A of the 1933 Act
or foreign securities which are offered or sold outside the U.S. The Fund's
practice of investing in Rule 144A securities could have the effect of
increasing the level of illiquidity in the Fund to the extent that qualified
institutional buyers become for a time uninterested in purchasing these
restricted securities.

     The Board of Trustees has the ultimate responsibility for determining
whether specific securities, including Rule 144A securities, are liquid or
illiquid. The Board has delegated the function of making day to day
determinations of liquidity to PMC, pursuant to guidelines reviewed by the
Trustees. PMC takes into account a number of factors in reaching liquidity
decisions. These factors may include but are not limited to: (i) the frequency
of trading in the security; (ii) the number of dealers who make quotes in the
securities; (iii) the number of dealers who have undertaken to make a market in
the security; (iv) the number of potential purchasers; and (v) the nature of the
security and how trading is effected (e.g., the time needed to sell the
security, how offers are solicited and the mechanics of transfer). PMC will
monitor the liquidity of securities in the Fund's portfolio and report
periodically to the Trustees.

REPURCHASE AGREEMENTS

     The Fund may enter into repurchase agreements not exceeding seven days in
duration. In a repurchase agreement, an investor (e.g., the Fund) purchases a
debt security from a seller which undertakes to repurchase the security at a
specified resale price on an agreed future date (ordinarily a week or less). The
resale price generally exceeds the purchase price by an amount which reflects an
agreed-upon market interest rate for the term of the repurchase agreement.
Repurchase agreements entered into by the Fund will be fully collateralized with
U.S. Treasury and/or U.S. government agency


                                       5


<PAGE>

obligations with a market value of not less than 100% of the obligation,
valued daily. Collateral will be held in a segregated, safekeeping account for
the benefit of the Fund. In the event that a repurchase agreement is not
fulfilled, the Fund could suffer a loss to the extent that the value of the
collateral falls below the repurchase price or if the Fund is prevented from
realizing the value of the collateral by reason of an order of a court with
jurisdiction over an insolvency proceeding with respect to the other party to
the repurchase agreement.    

INVESTMENT RESTRICTIONS

         It is a policy of the Fund not to concentrate its investments in
securities of companies in any particular industry. Following the current
opinion of the SEC, investments are concentrated in a particular industry if
such investments aggregate 25% or more of the Fund's total assets. The Fund's
policy does not apply to investments in U.S. government securities. The 1940 Act
provides that the policy of the Fund with respect to concentration is a
fundamental policy. In addition, the Fund has agreed not to change the foregoing
policy without the affirmative vote of a majority of the Fund's outstanding
shares of beneficial interest.

         FUNDAMENTAL INVESTMENT RESTRICTIONS. The Fund has adopted certain
investment restrictions which may not be changed without the affirmative vote of
the holders of a "majority of the outstanding voting securities" (as defined in
the 1940 Act) of the Fund. The Fund may not:

         (1) Issue senior securities, except as permitted by the Fund's
borrowing, lending and commodity restrictions, and for purposes of this
restriction, the issuance of shares of beneficial interest in multiple classes
or series, the purchase or sale of options, futures contracts and options on
futures contracts, forward commitments, forward foreign exchange contracts,
repurchase agreements, fully covered reverse repurchase agreements, dollar
rolls, swaps and any other financial transaction entered into pursuant to the
Fund's investment policies as described in the Prospectus and this Statement of
Additional Information and in accordance with applicable SEC pronouncements, as
well as the pledge, mortgage or hypothecation of the Fund's assets within the
meaning of the Fund's fundamental investment restriction regarding pledging, are
not deemed to be senior securities.

         (2) Borrow money, except from banks as a temporary measure to
facilitate the meeting of redemption requests or for extraordinary or emergency
purposes and except pursuant to reverse repurchase agreements or dollar rolls,
in all cases in amounts not exceeding 10% of the Fund's total assets (including
the amount borrowed) taken at market value. The Fund will not use leverage to
attempt to increase income. The Fund will not purchase securities while
outstanding borrowings (including reverse repurchase agreements and dollar
rolls) exceed 10% of the Fund's total assets.

         (3) Guarantee the securities of any other company, or mortgage, pledge,
hypothecate or assign or otherwise encumber as security for indebtedness its
securities or receivables in an amount exceeding the amount of the borrowing
secured thereby.


         (4) Purchase securities of a company if the purchase would result in
the Fund's having more than 5% of the value of its total assets invested in
securities of such company.

         (5) Purchase securities of a company if the purchase would result in
the Fund's owning more than 10% of the outstanding voting securities of such
company.


                                       6


<PAGE>


         (6) Act as an underwriter, except as it may deemed to be an underwriter
in a sale of restricted securities held in its portfolio.

         (7) Make loans, except by purchase of debt obligations in which the
Fund may invest consistent with its investment policies, by entering into
repurchase agreements or through the lending of portfolio securities, in each
case only to the extent permitted by the Prospectus and this Statement of
Additional Information.


         (8) Invest in real estate, commodities or commodity contracts, except
that the Fund may invest in financial futures contracts and related options and
in any other financial instruments which may be deemed to be commodities or
commodity contracts in which the Fund is not prohibited from investing by the
Commodity Exchange Act and the rules and regulations thereunder.

         (9) Purchase securities on margin or effect short sales of securities.


         (10) Purchase securities for the purpose of controlling management of
other companies.

         (11) Acquire the securities of any other domestic or foreign investment
company or investment fund (except in connection with a plan of merger or
consolidation with or acquisition of substantially all the assets of such other
investment company); provided, however, that nothing herein contained shall
prevent the Fund from investing in the securities issued by a real estate
investment trust, provided that such trust shall not be permitted to invest in
real estate or interests in real estate other than mortgages or other security
interests.

         The Fund does not intend to enter into any reverse repurchase agreement
or dollar roll, lend portfolio securities or invest in securities index put and
call warrants, as described in fundamental investment restrictions (1), (2), (7)
and (8) above, during the coming year.


     NON-FUNDAMENTAL INVESTMENT RESTRICTIONS. The following restriction has been
designated as non-fundamental and may be changed by a vote of the Fund's Board
of Trustees without approval of shareholders. The Fund may not:

         (1) purchase (a) securities which at the time of investment are not
readily marketable, (b) securities the disposition of which is restricted under
federal securities laws (excluding restricted securities that have been
determined by the Trustees of the Fund ((or the person designated by them to
make such determinations) to be readily marketable) and (c) repurchase
agreements maturing in more than seven days, if, as a result, more than 15% of
the Fund's net assets would be invested in securities described in (a), (b), and
(c) above.

         In addition, in connection with the offering of its shares in various
foreign countries, the Fund has agreed to abide by certain additional
restrictions which may not be changed without the approval of the regulatory
agencies in such foreign countries (but which may be changed without notice to
or approval of the Fund's shareholders). These restrictions are that the Fund
will not: (1) purchase the securities of any issuer if such purchase would
result in the Fund owning more than 10% of any class of securities of such
issuer; (2) write uncovered calls or puts or any combination thereof, purchase
calls, puts, straddles, spreads or any combination thereof in an amount
exceeding 5% of total assets, or invest in oil, gas or other mineral leases or
exploration or development programs; (3) borrow in excess of 10% of gross assets
taken at cost; and (4) pledge, mortgage, hypothecate or otherwise encumber any
assets of the Fund.

3. INVESTMENT ADVISER

         The Fund has contracted with PMC, 60 State Street, Boston,
Massachusetts 02109, to act as its investment adviser. PMC assists in the
management of the Fund and is authorized in its discretion to buy and sell
securities for the account of the Fund, subject to the right of the Fund's
Trustees to disapprove any such purchase or sale. The term of the management
contract is one year and is renewable annually by vote of a majority of the
Board of Trustees of the Fund (including a majority of the Trustees who are not
parties to the contract or interested persons of any such parties) cast in
person at a meeting called for the purpose of voting on such renewal. The
contract terminates if assigned and may be terminated without penalty by either
party by vote of its Board of Directors or Trustees or vote of a majority of the
Fund's outstanding securities and the giving of 60 days' written notice.
Pursuant to the management contract, PMC will not be liable for any error of
judgment or mistake of law or for any loss sustained by reason of the adoption
of any investment policy or the purchase, sale or retention of any securities on
the recommendation of PMC. PMC, however, is not protected against liability by
reason of willful misfeasance, bad faith or gross negligence in the performance
of its duties or by reason of its reckless disregard of its obligations and
duties under the management contract.

         As compensation for its management services and expenses incurred, and
certain expenses which PMC incurs on behalf of the Fund, the Fund pays PMC a
basic fee of 0.60% of the Fund's average daily net assets (the "Basic Fee"). An
appropriate percentage (based upon the number of days in the current month) of
this annual Basic Fee is applied to the Fund's average net assets for the
current month, giving a dollar amount which is the monthly fee.


                                       12


<PAGE>


PERFORMANCE FEE ADJUSTMENT

         The Basic Fee is subject to an upward or downward adjustment depending
on whether and to what extent the investment performance of the Class A shares
of the Fund for the performance period exceeds, or is exceeded by, the record of
the index determined by the Fund to be appropriate over the same period. The
Trustees have designated the Lipper Growth and Income Funds Index (the "Index")
for this purpose. The Index represents the arithmetic mean performance (i.e.,
equally weighted) of the 30 largest funds with a growth and income objective.

         The performance period consists of the current month and the prior 35
months ("performance period"). Each percentage point of difference (up to a
maximum of +/-10) is multiplied by a performance adjustment rate of 0.01%. The
maximum annualized adjustment rate is +/-0.10%. This performance comparison is
made at the end of each month. An appropriate percentage of this rate (based
upon the number of days in the current month) is then applied to the average net
assets for the entire performance period, giving a dollar amount that is added
to (or subtracted from) the Basic Fee.

         The Fund's performance is calculated based on the net asset value of
the Fund's Class A shares. For purposes of calculating the performance
adjustment, any dividends or capital gains distributions paid by the Fund are
treated as if reinvested at the net asset value as of the record date for
payment. The record for the Index is based on change in value and is adjusted
for any cash distributions from the mutual funds comprising the Index.

APPLICATION OF PERFORMANCE ADJUSTMENT

         The application of the performance adjustment is illustrated by the
following hypothetical example, assuming that the net asset value of the Class A
shares of the Fund and the level of the Index were $10 and 100, respectively, on
the first day of the performance period.

                  Investment Performance*           Cumulative Change
              First Day       End of Period     Absolute        Percentage
                                                                Points
Fund            $ 10             $ 13             +$ 3           + 30%
Index            100              123             + 23           + 23%

*Reflects performance at net asset value. Any dividends or capital gains
distributions paid by the Fund are treated as if reinvested at net asset value
as of the payment date and any dividends paid by the mutual funds comprising the
Index are treated as if reinvested on the ex-dividend date.

         The difference in relative performance for the performance period is +7
percentage points. Accordingly, the annualized management fee rate for the last
month of the performance period would be calculated as follows: an appropriate
percentage (based upon the number of days in the month) of the Basic Fee of
0.60% would be multiplied by the Fund's average daily net assets for the month
resulting in a dollar amount. The +7 percentage point difference is multiplied
by the performance adjustment rate of 0.01% producing a rate of 0.07%. An
appropriate percentage of this rate (based upon the number of days in the month)
is then multiplied by the average daily net assets of the Fund over the
performance period resulting in a dollar amount which is added to the dollar
amount of the Basic Fee. The management fee is the Basic Fee adjusted by the
dollar amount of the performance adjustment calculated for the performance
period. If the investment performance of the Index during the performance period
exceeded the


                                       13


<PAGE>


performance record of the Fund, the dollar amount of performance adjustment
would be deducted from the Basic Fee.

         Because the adjustment to the Basic Fee is based on the comparative
performance of the Fund and the record of the Index, the controlling factor is
not whether Fund performance is up or down, but whether it is up or down more or
less than the record of the Index. Moreover, the comparative investment of the
Fund is based solely on the relevant performance period without regard to the
cumulative performance over a longer or shorter period of time.

         From time to time, the Trustees may determine that another securities
index is a more appropriate benchmark than the Index for purposes of evaluating
the performance of the Fund. In such event, a successor index may be substituted
for the Index. However, the calculation of the performance adjustment for any
portion of the performance period prior to the adoption of the successor index
would still be based upon the Fund's performance compared to the Index.

         The Fund's current management contract with PMC became effective May 1,
1996. Under the terms of the contract, beginning on May 1, 1996 the Fund paid
management fees at a rate equal to the Basic Fee plus or minus the amount of the
performance adjustment for the current month and the preceding 35 months. At the
end of each succeeding month, the performance period will roll forward one month
so that it is always a 36-month period consisting of the current month and the
prior 35 months as described above. If including the initial rolling performance
period (that is, the period prior to the effectiveness of the management
contract) has the effect of increasing the Basic Fee for any month, such
aggregate prior results will be treated as Index neutral for purposes of
calculating the performance adjustment for such month. Otherwise, the
performance adjustment will be made as described above.

         The Basic Fee is computed daily, the performance fee adjustment is
calculated once per month and the entire management fee is normally paid
monthly.

         Prior to May 1, 1996, as compensation for its management services and
expenses incurred, PMC received 0.50% per annum of the Fund's average daily net
assets up to $250,000,000, 0.48% of such assets between $250,000,000 and
$300,000,000, and 0.45% of such assets in excess of $300,000,000. The fee was
computed daily and paid monthly.

         During its fiscal years ended December 31, 1997, 1996 and 1995, the
Fund paid or owed management fees to PMC of approximately $21,236,502,
$13,798,000 and $10,330,000, respectively.

4. SHAREHOLDER SERVICING/TRANSFER AGENT

         The Fund has contracted with PSC, 60 State Street, Boston,
Massachusetts 02109, to act as its shareholder servicing and transfer agent.
This contract may be terminated without penalty by either party upon 90 days'
written notice.

         Under the terms of its contract with the Fund, PSC services shareholder
accounts, and its duties include: (i) processing sales, redemptions and
exchanges of Fund shares; (ii) distributing dividends and capital gains
associated with Fund portfolio accounts; and (iii) maintaining account records
and responding to shareholder inquiries.

         PSC receives an annual fee of $22.75 per Class A, Class B and Class C
shareholder account from the Fund as compensation for the services described
above. PSC is also reimbursed by the Fund for its


                                       14


<PAGE>


out-of-pocket expenditures. The annual fee is set at an amount determined
by vote of a majority of the Trustees (including a majority of the Trustees who
are not parties to the contract with PSC or interested persons of any such
parties) to be comparable to fees for such services being paid by other
investment companies. The Fund may compensate entities which have agreed to
provide certain sub-accounting services such as specific transaction processing
and recordkeeping services. Any such payments by the Fund would be in lieu of
the per account fee which would otherwise be paid by the Fund to PSC.

5. CUSTODIAN

         Brown Brothers Harriman & Co., 40 Water Street, Boston, Massachusetts
02109, is the custodian (the "Custodian") of the Fund's assets. The Custodian's
responsibilities include safekeeping and controlling the Fund's cash and
securities, handling the receipt and delivery of securities, and collecting
interest and dividends on the Fund's investments. The Custodian does not
determine the investment policies of the Fund or decide which securities the
Fund will buy or sell. The Fund may invest in securities, including repurchase
agreements, issued by the Custodian and deal with the Custodian as principal in
securities transactions. Portfolio securities may be deposited into the Federal
Reserve-Treasury Department Book Entry System or the Depository Trust Company.

6. PRINCIPAL UNDERWRITER

         PFD, 60 State Street, Boston, Massachusetts 02109, serves as the
principal underwriter for the Fund in connection with the continuous offering of
its shares. During the fiscal years ended November 30, 1997, 1996 and 1995, net
underwriting commissions retained by PFD were $1,566,827, $1,176,156 and
$923,858, respectively. Commissions reallowed to dealers during such periods
were $10,273,818, $7,758,483 and $6,147,056, respectively.

         The Fund will not generally issue Fund shares for consideration other
than cash. At the Fund's sole discretion, however, it may issue Fund shares for
consideration other than cash in connection with a reorganization, statutory
merger or other acquisition of portfolio securities.

7. UNDERWRITING AGREEMENT AND DISTRIBUTION PLANS

   
         The Fund entered into an underwriting agreement, dated May 1, 1996,
with PFD. The underwriting agreement will continue from year to year if annually
approved by the Trustees. The underwriting agreement provides that PFD will bear
the expenses for the distribution of the Fund's shares, except for expenses
incurred by PFD for which it is reimbursed or compensated by the Fund under the
distribution plans (discussed below). PFD bears all expenses it incurs in
providing services under the underwriting agreement. Such expenses include
compensation to its employees and representatives and to securities dealers for
distribution-related services performed for the Fund. PFD also pays certain
expenses in connection with the distribution of the Fund's shares, including the
cost of preparing, printing and distributing advertising or promotional
materials, and the cost of printing and distributing prospectuses and
supplements to prospective shareholders. The Fund bears the cost of registering
its shares under federal, state and foreign securities law. The Fund and PFD
have agreed to indemnify each other against certain liabilities, including
liabilities under the 1933 Act. Under the underwriting agreement, PFD will use
its best efforts in rendering services to the Fund.    

         The Fund has adopted a plan of distribution pursuant to Rule 12b-1
under the 1940 Act with respect to its Class A, Class B and Class C shares (the
"Class A Plan," the "Class B Plan" and the "Class C Plan") (together, the
"Plans").


                                       15


<PAGE>


CLASS A PLAN

         Pursuant to the Class A Plan the Fund may reimburse PFD for its
expenditures in financing any activity primarily intended to result in the sale
of the Class A shares of the Fund. Certain categories of such expenditures have
been approved by the Board of Trustees and are set forth in the Prospectus. See
"Distribution Plans" in the Prospectus. The expenses of the Fund pursuant to the
Class A Plan are accrued on a fiscal year basis and may not exceed the annual
rate of 0.25% of the Fund's average annual net assets attributable to Class A
shares.

CLASS B PLAN

         The Class B Plan provides that the Fund shall pay PFD, as the Fund's
distributor for its Class B shares, a daily distribution fee equal on an annual
basis to 0.75% of the Fund's average daily net assets attributable to Class B
shares and will pay PFD a service fee equal to 0.25% of the Fund's average daily
net assets attributable to Class B shares (which PFD will in turn pay to
securities dealers which enter into a sales agreement with PFD at a rate of up
to 0.25% of the Fund's average daily net assets attributable to Class B shares
owned by investors for whom that securities dealer is the holder or dealer of
record). This service fee is intended to be in consideration of personal
services and/or account maintenance services rendered by the dealer with respect
to Class B shares. PFD will advance to dealers the first-year service fee at a
rate equal to 0.25% of the amount invested. As compensation therefor, PFD may
retain the service fee paid by the Fund with respect to such shares for the
first year after purchase. Dealers will become eligible for additional service
fees with respect to such shares commencing in the thirteenth month following
purchase. Dealers may from time to time be required to meet certain other
criteria in order to receive service fees. PFD or its affiliates are entitled to
retain all service fees payable under the Class B Plan for which there is no
dealer of record or for which qualification standards have not been met as
partial consideration for personal services and/or account maintenance services
performed by PFD or its affiliates for shareholder accounts.

         The purpose of distribution payments to PFD under the Class B Plan is
to compensate PFD for its distribution services with respect to Class B shares
of the Fund. PFD pays commissions to dealers as well as expenses of printing
prospectuses and reports used for sales purposes, expenses with respect to the
preparation and printing of sales literature and other distribution-related
expenses, including, without limitation, the cost necessary to provide
distribution-related services, or personnel, travel, office expenses and
equipment. The Class B Plan also provides that PFD will receive all CDSCs
attributable to Class B shares. (See "Distribution Plans" in the Prospectus.)
When a broker-dealer sells Class B shares and elects, with PFD's approval, to
waive its right to receive the commission normally paid at the time of the sale,
PFD may cause all or a portion of the distribution fees described above to be
paid to the broker-dealer.

CLASS C PLAN

         The Class C Plan provides that the Fund will pay PFD, as the Fund's
distributor for its Class C shares, a distribution fee accrued daily and paid
quarterly, equal on an annual basis to 0.75% of the Fund's average daily net
assets attributable to Class C shares and will pay PFD a service fee equal to
0.25% of the Fund's average daily net assets attributable to Class C shares. PFD
will in turn pay to securities dealers which enter into a sales agreement with
PFD a distribution fee and a service fee at rates of up to 0.75% and 0.25%,
respectively, of the Fund's average daily net assets attributable to Class C
shares owned by investors for whom that securities dealer is the holder or
dealer of record. The service fee is intended to be in consideration of personal
services and/or account maintenance services rendered


                                       16


<PAGE>


by the dealer with respect to Class C shares. PFD will advance to dealers
the first-year service fee at a rate equal to 0.25% of the amount invested. As
compensation therefor, PFD may retain the service fee paid by the Fund with
respect to such shares for the first year after purchase. Commencing in the
thirteenth month following a purchase of Class C shares, dealers will become
eligible for additional service fees at a rate of up to 0.25% of the current
value of the amount invested and additional compensation at a rate of up to
0.75% of the average net asset value with respect to such shares. Dealers may
from time to time be required to meet certain other criteria in order to receive
service fees. PFD or its affiliates are entitled to retain all service fees
payable under the Class C Plan for which there is no dealer of record or for
which qualification standards have not been met as partial consideration for
personal services and/or account maintenance services performed by PFD or its
affiliates for shareholder accounts.

         The purpose of distribution payments to PFD under the Class C Plan is
to compensate PFD for its distribution services with respect to the Class C
shares of the Fund. PFD pays commissions to dealers as well as expenses of
printing prospectuses and reports used for sales purposes, expenses with respect
to the preparation and printing of sales literature and other
distribution-related expenses, including, without limitation, the cost necessary
to provide distribution-related services, or personnel, travel, office expenses
and equipment. The Class C Plan also provides that PFD will receive all CDSCs
attributable to Class C shares. (See "Distribution Plans" in the Prospectus.)
When a broker-dealer sells Class C shares and elects, with PFD's approval, to
waive its right to receive the commission normally paid at the time of the sale,
PFD may cause all or a portion of the distribution fees described above to be
paid to the broker-dealer.

GENERAL

         In accordance with the terms of the Plans, PFD provides to the Fund for
review by the Trustees a quarterly written report of the amounts expended under
the respective Plans and the purpose for which such expenditures were made. In
the Trustees' quarterly review of the Plans, they will consider the continued
appropriateness and the level of reimbursement or compensation the Plans
provide.

         No interested person of the Fund, nor any Trustee of the Fund who is
not an interested person of the Fund, has any direct or indirect financial
interest in the operation of the Plans except to the extent that PFD and certain
of its employees may be deemed to have such an interest as a result of receiving
a portion of the amounts expended under the Plans by the Fund and except to the
extent certain officers may have an interest in PFD's ultimate parent, PGI.

     The Plans were adopted by a majority vote of the Board of Trustees,
including all of the Trustees who are not, and were not at the time they voted,
interested persons of the Fund, as defined in the 1940 Act (none of whom has or
had any direct or indirect financial interest in the operation of the Plans),
cast in person at a meeting called for the purpose of voting on the Plans. In
approving the Plans, the Trustees identified and considered a number of
potential benefits which the Plans may provide. The Board of Trustees believes
that there is a reasonable likelihood that the Plans will benefit the Fund and
its current and future shareholders. Under their terms, the Plans remain in
effect from year to year provided such continuance is approved annually by vote
of the Trustees in the manner described above. The Plans may not be amended to
increase materially the annual percentage limitation of average net assets which
may be spent for the services described therein without approval of the
shareholders of the Fund affected thereby, and material amendments of the Plans
must also be approved by the Trustees in the manner described above. A Plan may
be terminated at any time, without payment of any penalty, by vote of the
majority of the Trustees who are not interested persons of the Fund and who have
no direct or indirect financial interest in the operations of the Plan, or by a
vote of a majority of the outstanding voting securities (as defined in the


                                       17


<PAGE>


1940 Act) of the respective class of the Fund. A Plan will automatically
terminate in the event of its assignment (as defined in the 1940 Act).

         During the fiscal year ended December 31, 1997, the Fund incurred total
distribution fees pursuant to the Fund's Class A Plan, Class B Plan and Class C
Plan, respectively, as follows: $6,845,927, $268,672 and $44,536. Distribution
fees were paid by the Fund to PFD in reimbursement of or as compensation for
expenses related to servicing shareholder accounts and to compensate dealers and
sales personnel.

         Redemptions of each class of shares may be subject to a CDSC. A CDSC of
1.00% may be imposed on redemptions of certain net asset value purchases of
Class A shares within one year of purchase. Class B shares that are redeemed
within six years of purchase are subject to a CDSC at declining rates beginning
at 4% based on the lower of the cost or market value of the shares being
redeemed. Redemptions of Class C shares within one year of purchase are subject
to a CDSC of 1.00%. See "How to Buy Fund Shares" in the Prospectus. During the
fiscal year ended December 31, 1997, CDSCs in the amount of $21,916 were paid to
PFD.

8. INDEPENDENT PUBLIC ACCOUNTANTS

         Arthur Andersen LLP, 225 Franklin Street, Boston, Massachusetts 02210,
is the Fund's independent public accountants, providing audit services, tax
return review, and assistance and consultation with respect to the preparation
of filings with the SEC.

9. PORTFOLIO TRANSACTIONS

     All orders for the purchase or sale of portfolio securities are placed on
behalf of the Fund by PMC pursuant to authority contained in the management
contract. In selecting brokers or dealers, PMC considers various relevant
factors, including, but not limited to, the size and type of the transaction;
the nature and character of the markets for the security to be purchased or
sold; the execution efficiency, settlement capability, and financial condition
of the dealer; the dealer's execution service rendered on a continuing basis;
and the reasonableness of any dealer spreads.

         PMC may select broker-dealers which provide brokerage and/or research
services to the Fund and/or other investment companies or accounts managed by
PMC. In addition, consistent with Section 28(e) of the Securities Act of 1934,
as amended, the Fund may pay commissions to such broker-dealers in an amount
greater than the amount another firm might charge. Such services may include
advice concerning the value of securities; the advisability of investing in,
purchasing or selling securities; the availability of securities or the
purchasers or sellers of securities; providing stock price quotation services;
furnishing analyses, electronic information services, manuals and reports
concerning issuers, industries, securities, economic factors and trends,
portfolio strategy, performance of accounts, comparative fund statistics and
credit rating service information; and effecting securities transactions and
performing functions incidental thereto (such as clearance and settlement). PMC
maintains a listing of dealers who provide such services on a regular basis.
However, because many transactions on behalf of the Fund and other investment
companies or accounts managed by PMC are placed with broker-dealers (including
broker-dealers on the listing) without regard to the furnishing of such
services, it is not possible to estimate the proportion of such transactions
directed to such dealers solely because such services were provided. Management
believes that no exact dollar value can be calculated for such services.


                                       18


<PAGE>


         The research received from broker-dealers may be useful to PMC in
rendering investment management services to the Fund and other investment
companies or accounts managed by PMC, although not all of such research may be
useful to the Fund. Conversely, such information provided by brokers or dealers
who have executed transaction orders on behalf of such other PMC clients may be
useful to PMC in carrying out its obligations to the Fund. The receipt of such
research has not reduced PMC's normal independent research activities; however,
it enables PMC to avoid the additional expenses which might otherwise be
incurred if it were to attempt to develop comparable information through its own
staff.

         In circumstances where two or more broker-dealers offer comparable
prices and executions, preference may be given to a broker-dealer which has sold
shares of the Fund as well as shares of other investment companies or accounts
managed by PMC. This policy does not imply a commitment to execute all portfolio
transactions through all broker-dealers that sell shares of the Fund. For the
fiscal years ended December 31, 1997, 1996 and 1995, the Fund paid or accrued
aggregate brokerage commissions of $1,265,137, $1,543,744 and $1,983,083,
respectively. Differences in brokerage commissions reflected above resulted from
decreased portfolio turnover throughout the respective periods. See "Financial
Highlights" in the Prospectus.

         In addition to the Fund, PMC acts as investment adviser to other
Pioneer mutual funds and certain private accounts with investment objectives
similar to those of the Fund. As such, securities may frequently meet the
investment objectives of the Fund, such other mutual funds and such private
accounts. In such cases, the decision to recommend a purchase to one mutual fund
or account rather than the other is based on a number of factors. The
determining factors in most cases are the amount of securities of the issuer
then outstanding, the value of those securities and the market for them. Other
factors considered in the investment recommendations include other investments
which each fund or account presently has in a particular industry and the
availability of investment funds in each fund or account.

         It is possible that at times identical securities will be held by more
than one fund and/or account. However, positions in the same issue may vary and
the length of time that any fund or account may choose to hold its investment in
the same issue may likewise vary. To the extent that the Fund, another Pioneer
mutual fund or a private account managed by PMC seeks to acquire the same
security at about the same time, the Fund may not be able to acquire as large a
position in such security as it desires or it may have to pay a higher price for
the security. Similarly, the Fund may not be able to obtain as large an
execution of an order to sell or as high a price for any particular portfolio
security if PMC decides to sell on behalf of another account the same portfolio
security at the same time. On the other hand, if the same securities are bought
or sold at the same time by more than one fund or account, the resulting
participation in volume transactions could produce better executions for the
Fund or the account. In the event that more than one account purchases or sells
the same security on a given date, the purchases and sales will normally be made
as nearly as practicable on a pro rata basis in proportion to the amounts
desired to be purchased or sold by each.

         The Trustees periodically review PMC's performance of its
responsibilities in connection with the placement of portfolio transactions on
behalf of the Fund.

10. TAX STATUS

         It is the Fund's policy to meet the requirements of Subchapter M of the
Code for qualification as a regulated investment company. These requirements
relate to the sources of the Fund's income, the diversification of its assets
and the distribution of its income to shareholders. If the Fund meets all such



                                       19


<PAGE>


requirements and distributes to its shareholders, in accordance with the Code's
timing requirements, all investment company taxable income and net capital gain,
if any, which it earns, the Fund will be relieved of the necessity of paying
federal income tax.

         In order to qualify as a regulated investment company under Subchapter
M, the Fund must, among other things, derive at least 90% of its annual gross
income from dividends, interest, payments with respect to securities loans,
gains from the sale or other disposition of stock, securities or foreign
currencies, or other income (including gains from options) derived with respect
to its business of investing in such stock, securities or currencies (the "90%
income test") and satisfy certain annual distribution and quarterly
diversification requirements. For purposes of the 90% income test, income the
Fund earns from equity interests in certain entities that are not treated as
corporations (e.g., are treated as partnerships or trusts) for U.S. tax purposes
will generally have the same character for the Fund as in the hands of such
entities; consequently, the Fund may be required to limit its equity investments
in such entities that earn fee income, rental income, or other nonqualifying
income.

         Dividends from investment company taxable income, which includes net
investment income, net short-term capital gain in excess of net long-term
capital loss, and certain net foreign exchange gains, are taxable as ordinary
income, whether received in cash or reinvested in additional shares. Dividends
from net long-term capital gain in excess of net short-term capital loss ("net
capital gain"), if any, whether received in cash or reinvested in additional
shares, are taxable to the Fund's shareholders as capital gains for federal
income tax purposes without regard to the length of time shares of the Fund have
been held. As a result of the enactment of the Taxpayer Relief Act of 1997 (the
"1997 TRA") on August 5, 1997, gain recognized after May 6, 1997 from the sale
of a capital asset is taxable to individual (noncorporate) investors at
different maximum federal income tax rates, depending generally upon the tax
holding period for the asset, the federal income tax bracket of the taxpayer,
and the dates the asset was acquired and/or sold. The Treasury Department has
issued guidance under the 1997 TRA that (subject to possible modification by
future "technical corrections" legislation) enables the Fund to pass through to
its shareholders the benefits of the capital gains tax rates enacted in the 1997
TRA. The Fund will provide appropriate information to its shareholders about its
distributions, including the tax rate(s) applicable to its distributions from
long-term capital gains, in accordance with this and any future guidance.
Shareholders should consult their own tax advisers on the correct application of
these new rules in their particular circumstances.

         Any dividend declared by the Fund in October, November or December as
of a record date in such a month and paid during the following January will be
treated for federal income tax purposes as received by shareholders on December
31 of the calendar year in which it is declared.

         Foreign exchange gains and losses realized by the Fund in connection
with certain transactions involving foreign currency-denominated debt
securities, foreign currencies, or payables or receivables denominated in a
foreign currency are subject to Section 988 of the Code, which generally causes
such gains and losses to be treated as ordinary income and losses and may affect
the amount, timing and character of distributions to shareholders. Under future
regulations, any transactions in foreign currency that are not directly related
to the Fund's investments in stock or securities (or its options with respect to
stock or securities) may need to be limited in order to enable the Fund to
satisfy the 90% income test. If the net foreign exchange loss for a year were to
exceed the Fund's investment company taxable income (computed without regard to
such loss), the resulting ordinary loss for such year would not be deductible by
the Fund or its shareholders in future years.


                                       20


<PAGE>


         If the Fund acquires any equity interest (under proposed regulations,
generally including not only stock but also an option to acquire stock such as
is inherent in a convertible bond) in certain foreign corporations that receive
at least 75% of their annual gross income from passive sources (such as
interest, dividends, certain rents and royalties, or capital gains) or hold at
least 50% of their assets in investments producing such passive income ("passive
foreign investment companies"), the Fund could be subject to federal income tax
and additional interest charges on "excess distributions" received from such
companies or gain from the sale of stock in such companies, even if all income
or gain actually received by the Fund is timely distributed to its shareholders.
The Fund would not be able to pass through to its shareholders any credit or
deduction for such a tax. An election may generally be available that would
ameliorate these adverse tax consequences, but any such election could require
the Fund to recognize taxable income or gain (subject to tax distribution
requirements) without the concurrent receipt of cash. These investments could
also result in the treatment of associated capital gains as ordinary income. The
Fund may limit and/or manage its holdings in passive foreign investment
companies to minimize its tax liability or maximize its return from these
investments.

         The Fund may invest to a limited extent in debt obligations that are in
the lowest rating categories or are unrated, including debt obligations of
issuers not currently paying interest or who are in default. Investments in debt
obligations that are at risk of or in default present special tax issues for the
Fund. Tax rules are not entirely clear about issues such as when the Fund may
cease to accrue interest, original issue discount, or market discount, when and
to what extent deductions may be taken for bad debts or worthless securities,
how payments received on obligations in default should be allocated between
principal and income, and whether exchanges of debt obligations in a workout
context are taxable. These and other issues will be addressed by the Fund, in
the event it invests in such securities, in order to seek to ensure that it
distributes sufficient income to preserve its status as a regulated investment
company and does not become subject to federal income or excise tax.

         If the Fund invests in certain pay-in-kind securities ("PIKs"), zero
coupon securities, deferred interest securities or, in general, any other
securities with original issue discount (or with market discount if the Fund
elects to include market discount in income currently), the Fund must accrue
income on such investments for each taxable year, which generally will be prior
to the receipt of the corresponding cash payments. However, the Fund must
distribute, at least annually, all or substantially all of its net income,
including such accrued income, to shareholders to qualify as a regulated
investment company under the Code and avoid federal income and excise taxes.
Therefore, the Fund may have to dispose of its portfolio securities under
disadvantageous circumstances to generate cash, or may have to leverage itself
by borrowing the cash, to satisfy distribution requirements.

         For federal income tax purposes, the Fund is permitted to carry forward
a net capital loss for any year to offset its capital gains, if any, during the
eight years following the year of the loss. To the extent subsequent capital
gains are offset by such losses, they would not result in federal income tax
liability to the Fund and therefore are not expected to be distributed as such
to shareholders. As of the end of its most recent taxable year, the Fund had no
capital loss carryforwards.

         At the time of an investor's purchase of Fund shares, a portion of the
purchase price may be attributable to realized or unrealized appreciation in the
Fund's portfolio or undistributed taxable income of the Fund. Consequently,
subsequent distributions by the Fund on these shares from such appreciation or
income may be taxable to such investor even if the net asset value of the
investor's shares is, as a result of the distributions, reduced below the
investor's cost for such shares and the distributions economically represent a
return of a portion of the investment.


                                       21


<PAGE>


         Redemptions and exchanges are taxable events for shareholders that are
subject to tax. Shareholders should consult their own tax advisers with
reference to their individual circumstances to determine whether any particular
transaction in Fund shares is properly treated as a sale for tax purposes, as
the following discussion assumes, and the character of and tax rate applicable
to any gains or losses recognized in such transactions under the new rate
structure enacted in the 1997 TRA. Any loss realized by a shareholder upon the
redemption, exchange or other disposition of shares with a tax holding period of
six months or less will be treated as a long-term capital loss to the extent of
any amounts treated as distributions of long-term capital gain with respect to
such shares.

         In addition, if Class A shares redeemed or exchanged have been held for
less than 91 days, (1) in the case of a reinvestment in the Fund at net asset
value pursuant to the reinvestment privilege, the sales charge paid on such
shares is not included in their tax basis under the Code, and (2) in the case of
an exchange, all or a portion of the sales charge paid on such shares is not
included in their tax basis under the Code, to the extent a sales charge that
would otherwise apply to the shares received is reduced pursuant to the exchange
privilege. In either case, the portion of the sales charge not included in the
tax basis of the shares redeemed or surrendered in an exchange is included in
the tax basis of the shares acquired in the reinvestment or exchange. Losses on
redemptions or other dispositions of shares may be disallowed under "wash sale"
rules in the event of other investments in the Fund (including those made
pursuant to reinvestment of dividends and/or capital gain distributions) within
a period of 61 days beginning 30 days before and ending 30 days after a
redemption or other disposition of shares. In such a case, the disallowed
portion of any loss would be included in the federal tax basis of the shares
acquired in the other investments.

         Options written by the Fund on certain securities may cause the Fund to
recognize gains or losses from marking-to-market even though such options may
not have lapsed, been closed out, or exercised. The tax rules applicable to
these contracts may affect the characterization as long-term or short-term of
some capital gains and losses realized by the Fund. Additionally, the Fund may
be required to recognize gain if an option or other transaction that is not
subject to the mark to market rules is treated as a "constructive sale" of an
"appreciated financial position" held by the Fund under Section 1259 of the
Code. Any net mark to market gains and/or gains from constructive sales may also
have to be distributed to satisfy the distribution requirements referred to
above even though no corresponding cash amounts may concurrently be received,
possibly requiring the disposition of portfolio securities or borrowing to
obtain the necessary cash. Losses on certain options and/or offsetting positions
(portfolio securities or other positions with respect to which the Fund's risk
of loss is substantially diminished by one or more options) may also be deferred
under the tax straddle rules of the Code, which may also affect the
characterization of capital gains or losses from straddle positions and certain
successor positions as long-term or short-term. The effect of these rules may be
mitigated to the extent the Fund limits its option-writing to "qualified covered
call options" on portfolio stock. Certain tax elections may be available that
would enable the Fund to ameliorate some adverse effects of the tax rules
described in this paragraph. The tax rules applicable to options and straddles
may affect the amount, timing and character of the Fund's income and losses and
hence of its distributions to shareholders.

         For purposes of the 70% dividends-received deduction generally
available to corporations under the Code, dividends received by the Fund from
U.S. corporations in respect of any share of stock with a tax holding period of
at least 46 days (91 days in the case of certain preferred stock) extending
before and after each dividend held in an unleveraged position and distributed
and designated by the Fund may be treated as qualifying dividends. Any corporate
shareholder should consult its tax advisor regarding the possibility that its
tax basis in its shares may be reduced, for federal income tax purposes, by
reason of "extraordinary dividends" received with respect to the shares and, to
the extent such basis would be


                                       22


<PAGE>


reduced below zero, current recognition of income may be required. In order
to qualify for the deduction, corporate shareholders must meet the minimum
holding period requirement stated above with respect to their Fund shares,
taking into account any holding period reductions from certain hedging or other
transactions or positions that diminish their risk of loss with respect to their
Fund shares, and, if they borrow to acquire or otherwise incur debt attributable
to Fund shares, they may be denied a portion of the dividends-received
deduction. The entire qualifying dividend, including the otherwise deductible
amount, will be included in determining the excess (if any) of a corporation's
adjusted current earnings over its alternative minimum taxable income, which may
increase a corporation's alternative minimum tax liability.

         The Fund may be subject to withholding and other taxes imposed by
foreign countries including taxes on interest, dividends and capital gains with
respect to its investments in those countries. Tax conventions between certain
countries and the U.S. may reduce or eliminate such taxes in some cases. The
Fund does not expect to satisfy the requirements for passing through to its
shareholders their pro rata shares of qualified foreign taxes paid by the Fund,
with the result that shareholders will not include such taxes in their gross
incomes and will not be entitled to a tax deduction or credit for such taxes on
their own tax returns.

         Different tax treatment, including penalties on certain excess
contributions and deferrals, certain pre-retirement and post-retirement
distributions, and certain prohibited transactions, is accorded to accounts
maintained as qualified retirement plans. Shareholders should consult their tax
advisers for more information.

         Federal law requires that the Fund withhold (as "backup withholding")
31% of reportable payments, including dividends, capital gain dividends and the
proceeds of redemptions (including exchanges) and repurchases to shareholders
who have not complied with IRS regulations. In order to avoid this withholding
requirement, shareholders must certify on their Account Applications, or on
separate IRS Forms W-9, that the Social Security Number or other Taxpayer
Identification Number they provide is their correct number and that they are not
currently subject to backup withholding, or that they are exempt from backup
withholding. The Fund may nevertheless be required to withhold if it receives
notice from the IRS or a broker that the number provided is incorrect or backup
withholding is applicable as a result of previous underreporting of interest or
dividend income.

         If, as anticipated, the Fund continues to qualify as a regulated
investment company under the Code, it will not be required to pay any
Massachusetts income, corporate excise or franchise taxes or any Delaware
corporation income tax.

         The description of certain federal tax provisions above relates only to
U.S. federal income tax consequences for shareholders who are U.S. persons, i.e.
U.S. citizens or residents or U.S. corporations, partnerships, trusts or
estates, and who are subject to U.S. federal income tax. This description does
not address the special tax rules that may be applicable to particular types of
investors, such as financial institutions, insurance companies, securities
dealers, or tax-exempt or tax-deferred plans, accounts or entities. Investors
other than U.S. persons may be subject to different U.S. tax treatment,
including a possible 30% non-resident alien U.S. withholding tax (or
non-resident alien withholding tax at a lower treaty rate) on amounts treated as
ordinary dividends from the Fund and, unless an effective IRS Form W-8 or
authorized substitute for Form W-8 is on file, to 31% backup withholding on
certain other payments from the Fund. Shareholders should consult their own tax
advisers on these matters and on state, local and other applicable tax laws.

11. DESCRIPTION OF SHARES

         The Declaration permits its Board of Trustees to authorize the issuance
of an unlimited number of full and fractional shares of beneficial interest
(without par value) which may be divided into such separate series as the
Trustees may establish. Currently, the Fund consists of only one series. The
Trustees may establish additional series of shares, and may divide or combine
the shares into a greater or lesser number of shares without thereby changing
the proportionate beneficial interests in the Fund. The Declaration further
authorizes the Trustees to classify or reclassify any series of the shares into
one or more classes. Pursuant thereto, the Trustees have authorized the issuance
of three classes of shares of the Fund, designated Class A, Class B and Class C
shares. Each share of a class represents an equal proportionate interest in the
assets of the Fund allocable to that class. Upon liquidation of the Fund,
shareholders of each class of the Fund are entitled to share pro rata in the
Fund's net assets allocable to such class available for distribution to
shareholders. The Fund reserves the right to create and issue additional series
or classes of shares, in which case the shares of each class of a series would
participate equally in the earnings, dividends and assets allocable to that
class of the particular series.

         Shareholders are entitled to one vote for each share held and may vote
in the election of Trustees and on other matters submitted to meetings of
shareholders. Although Trustees are not elected annually by the shareholders,
shareholders have, under certain circumstances, the right to remove one or more
Trustees.

         The shares of each series of the Fund are entitled to vote separately
to approve investment advisory agreements or changes in investment restrictions,
but shareholders of all series vote together in the election and selection of
Trustees and accountants. Shares of all series of the Fund vote together as a
class on matters that affect all series of the Fund in substantially the same
manner. As to matters affecting a single series or class, shares of such series
or class will vote separately. No amendment adversely affecting the rights of
shareholders may be made to the Declaration without the affirmative vote of a
majority of its shares. Shares have no preemptive or conversion rights. Shares
are fully paid and non-assessable by the Fund, except as stated below.

12. CERTAIN LIABILITIES

         The Fund has previously been organized as a Delaware corporation, a
Massachusetts corporation and a Massachusetts business trust and was reorganized
as a Delaware business trust on May 1, 1996, pursuant to an Agreement and Plan
of Reorganization approved by the shareholders of the Fund. As a Delaware
business trust, the Fund's operations are governed by the Declaration. A copy of
the Fund's Certificate of Trust, dated May 1, 1996, is on file with the office
of the Secretary of State of Delaware. Generally, Delaware business trust
shareholders are not personally liable for obligations of the Delaware business
trust under Delaware law. The Delaware Business Trust Act (the "Delaware Act")
provides that a shareholder of a Delaware business trust shall be entitled to
the same limitation of liability extended to shareholders of private for-profit
corporations. The Declaration expressly provides that the Fund is organized
under the Delaware Act and that the Declaration is to be governed by Delaware
law. There is nevertheless a remote possibility that a Delaware business trust,
such as the Fund, might become a party to an action in another state whose
courts refused to apply Delaware law, in which case the trust's shareholders
could become subject to personal liability.


         To guard against this risk, the Declaration (i) contains an express
disclaimer of shareholder liability for acts or obligations of the Fund and
provides that notice of such disclaimer may be given in each agreement,
obligation or instrument entered into or executed by the Fund or its Trustees,



                                       24


<PAGE>


(ii) provides for the indemnification out of Fund property of any shareholders
held personally liable for any obligations of the Fund or any series of the Fund
and (iii) provides that the Fund shall, upon request, assume the defense of any
claim made against any shareholder for any act or obligation of the Fund and
satisfy any judgment thereon. Thus, the risk of a shareholder incurring
financial loss beyond his or her investment because of shareholder liability is
limited to circumstances in which all of the following factors are present: (1)
a court refused to apply Delaware law; (2) the liability arose under tort law
or, if not, no contractual limitation of liability was in effect; and (3) the
Fund itself would be unable to meet its obligations. In light of Delaware law,
the nature of the Fund's business and the nature of its assets, the risk of
personal liability to a Fund shareholder is remote.

         The Declaration further provides that the Fund shall indemnify each of
its Trustees and officers against liabilities and expenses reasonably incurred
by them, in connection with, or arising out of, any action, suit or proceeding,
threatened against or otherwise involving such Trustee or officer, directly or
indirectly, by reason of being or having been a Trustee or officer of the Fund.
The Declaration does not authorize the Fund to indemnify any Trustee or officer
against any liability to which he or she would otherwise be subject by reason of
or for willful misfeasance, bad faith, gross negligence or reckless disregard of
such person's duties.

13. DETERMINATION OF NET ASSET VALUE

         The net asset value per share of each class of the Fund is determined
as of the close of regular trading on the Exchange (normally 4:00 p.m., Eastern
time) on each day on which the Exchange is open for trading. As of the date of
this Statement of Additional Information, the Exchange is open for trading every
weekday except for the following holidays: New Year's Day, Martin Luther King,
Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor
Day, Thanksgiving Day and Christmas Day. The net asset value per share of each
class of the Fund is also determined on any other day in which the level of
trading in its portfolio securities is sufficiently high so that the current net
asset value per share might be materially affected by changes in the value of
its portfolio securities. The net asset value per share of the Fund is not
determined on any day in which no purchase orders in good order for the shares
of the Fund are received and no shares are tendered for redemption.

         The net asset value per share of each class of the Fund is computed by
taking the value of all of the Fund's assets attributable to a class, less the
Fund's liabilities attributable to that class, and dividing the result by the
number of outstanding shares of the class. For purposes of determining net asset
value, expenses of the classes of the Fund are accrued daily.

         Securities which have not traded on the date of valuation or securities
for which sales prices are not generally reported are valued at the mean between
the last bid and asked prices. Securities for which no market quotations are
readily available (including those the trading of which has been suspended) will
be valued at fair value as determined in good faith by the Board of Trustees,
although the actual computations may be made by persons acting pursuant to the
direction of the Board of Trustees. The maximum offering price per Class A share
is the net asset value per Class A share, plus the maximum sales charge. Class B
and Class C shares are offered at net asset value without the imposition of an
initial sales charge.

14. SYSTEMATIC WITHDRAWAL PLAN


         The Systematic Withdrawal Plan ("SWP") is designed to provide a
convenient method of receiving fixed payments at regular intervals from shares
of the Fund deposited by the applicant under the


                                       25


<PAGE>


SWP. The applicant must deposit or purchase for deposit with PSC shares
of the Fund having a total value of not less than $10,000. Periodic payments of
$50 or more will be deposited monthly or quarterly directly into a bank account
designated by the applicant, or will be sent by check to the applicant, or any
person designated by the applicant. Class B accounts must meet the minimum
initial investment requirement prior to establishing a SWP. Withdrawals from
Class B and Class C accounts are limited to 10% of the value of the account at
the time the SWP is established. See "Waiver or Reduction of Contingent Deferred
Sales Charge" in the Prospectus. Designation of another person to receive the
payments subsequent to opening an account must be accompanied by a signature
guarantee.

         Any income dividends or capital gains distributions on shares under the
SWP will be credited to the SWP account on the payment date in full and
fractional shares at the net asset value per share in effect on the record date.

         SWP payments are made from the proceeds of the redemption of shares
deposited under the SWP in a SWP account. To the extent that such redemptions
for periodic withdrawals exceed dividend income reinvested in the SWP account,
such redemptions will reduce and may ultimately exhaust the number of shares
deposited in the Plan account. Redemptions are potentially taxable transactions
to shareholders. In addition, the amounts received by a shareholder cannot be
considered as an actual yield or income on his or her investment because part of
such payments may be a return of his or her investment.

         The SWP may be terminated at any time (1) by written notice to PSC or
from PSC to the shareholder; (2) upon receipt by PSC of appropriate evidence of
the shareholder's death; or (3) when all shares under the SWP have been
redeemed.

15. LETTER OF INTENT (CLASS A SHARES ONLY)


         A Letter of Intent ("LOI") may be established by completing the LOI
section of the Account Application. When you sign the Account Application, you
agree to irrevocably appoint PSC your attorney-in-fact to surrender for
redemption any or all shares held in escrow with full power of substitution. An
LOI is not a binding obligation upon the investor to purchase, or the Fund to
sell, the full amount indicated.

         If the total purchases, less redemptions, exceed the amount specified
under the LOI and are in an amount which would qualify for a further quantity
discount, all transactions will be recomputed on the expiration date of the LOI
to effect the lower sales charge. Any difference in the sales charge resulting
from such recomputation will be either delivered to you in cash or invested in
additional shares at the lower sales charge. The dealer, by signing the Account
Application, agrees to return to PFD, as part of such retroactive adjustment,
the excess of the commission previously reallowed or paid to the dealer over
that which is applicable to the actual amount of the total purchases under the
LOI.

         If the total purchases, less redemptions, are less than the amount
specified under the LOI, you must remit to PFD any difference between the sales
charge on the amount actually purchased and the amount originally specified in
the LOI section of the Account Application. When the difference is paid, the
shares held in escrow will be deposited to your account. If you do not pay the
difference in sales charge within 20 days after written request from PFD or your
dealer, PSC, after receiving instructions from PFD, will redeem the appropriate
number of shares held in escrow to realize the difference and release any
excess. See "How to Purchase Fund Shares Letter of Intent" in the Prospectus for
more information.

16. INVESTMENT RESULTS

QUOTATIONS, COMPARISONS, AND GENERAL INFORMATION

         From time to time, in advertisements, in sales literature, or in
reports to shareholders, the past performance of the Fund may be illustrated
and/or compared to that of other mutual funds with similar investment objectives
and to stock or other relevant indices. For example, the total return of the
Fund's classes may be compared to averages or rankings prepared by LIPPER
ANALYTICAL SERVICES, INC., a widely recognized independent service which
monitors mutual fund performance; STANDARD & POOR'S 500 STOCK INDEX (the "S&P
500"), an index of unmanaged groups of common stock; the DOW JONES INDUSTRIAL
AVERAGE, a recognized unmanaged index of common stocks of 30 industrial
companies listed on the Exchange; or the RUSSELL U.S. EQUITY INDEXES or the
WILSHIRE TOTAL MARKET VALUE INDEX, which are recognized unmanaged indexes of
broad-based common stocks.

         In addition, the performance of the classes of the Fund may be compared
to alternative investment or savings vehicles and/or to indices or indicators of
economic activity, e.g., inflation or interest rates. Performance rankings and
listings reported in newspapers or national business and financial publications,
such as BARRON'S, BUSINESS WEEK, CONSUMERS DIGEST, CONSUMER REPORTS, FINANCIAL

literature, or in reports to shareholders of the Fund.

STANDARDIZED AVERAGE ANNUAL TOTAL RETURN
QUOTATIONS AND OTHER PERFORMANCE QUOTATIONS


         One of the primary methods used to measure the performance of a class
of the Fund is "total return." Total return will normally represent the
percentage change in value of an account, or of a hypothetical investment in a
class of the Fund, over any period up to the lifetime of that class of the Fund.
Total return calculations will usually assume the reinvestment of all dividends
and capital gains distributions and will be expressed as a percentage increase
or decrease from an initial value for the entire period or for one or more
specified periods within the entire period. Total return percentages for periods
of less than one year will usually be annualized; total return percentages for
periods longer than one year will usually be accompanied by total return
percentages for each year within the period and/or the average annual compounded
total return for the period. The income and capital components of a given return
may be separated and portrayed in a variety of ways in order to illustrate their
relative significance. Performance may also be portrayed in terms of cash or
investment values, without percentages. Past performance cannot guarantee any
particular future result.

         The Fund's average annual total return quotations for each of its
classes as that information may appear in the Prospectus, this Statement of
Additional Information or in advertising are calculated by standard methods
prescribed by the SEC.


                                       27


<PAGE>



         Average annual total return quotations for each class of Fund shares
are computed by finding the average annual compounded rates of return that would
cause a hypothetical investment in the class made on the first day of a
designated period (assuming all dividends and distributions are reinvested) to
equal the ending redeemable value of such hypothetical investment on the last
day of the designated period in accordance with the following formula:

                  P(1+T)n = ERV

Where:
                  P        =        a hypothetical initial payment of $1,000,
                                    less the maximum sales load of 5.75% for
                                    Class A shares or the deduction of the CDSC
                                    for Class B and Class C shares at the end of
                                    the period

                  T        =        average annual total return

                  n        =        number of years

                  ERV      =        ending redeemable value of the hypothetical
                                    $1,000 initial payment made at the
                                    beginning of the designated period (or
                                    fractional portion thereof)

         For purposes of the above computation, it is assumed that all dividends
and distributions made by the Fund are reinvested at net asset value during the
designated period. The average annual total return quotation is determined to
the nearest 1/100 of 1%.

         In determining the average annual total return (calculated as provided
above), recurring fees, if any, that are charged to all shareholder accounts of
a particular class of shares are taken into consideration. For any account fees
that vary with the size of the account, the account fee used for purposes of the
above computation is assumed to be the fee that would be charged to the class'
mean account size.

         The average annual total returns for Class A, Class B and Class C
shares of the Fund as of December 31, 1997 are as follows:

                                Average Annual Total Return (%)

                  One Year    Five Years    Ten Years    Since Inception*

Class A Shares      30.51       17.58         15.13          13.20**
Class B Shares      33.19       N/A           N/A            29.17
Class C Shares      37.25       N/A           N/A            30.60

*Inception was February 13, 1928 for Class A Shares and July 1, 1996for both
Class B and Class C shares. **Return calculated from March 1, 1928.

         The Fund may also present, from time to time, historical information
depicting the value of a hypothetical account over the time period from the
Fund's inception in 1928 until the present. The Fund also may depict summary
results of assumed investments in the Fund for each of the ten-calendar-year
periods in the Fund's history and for the ten-year periods which began at
recognized market highs or ended at recognized market lows. An example of this
historical information describing various performance characteristics of the
Fund from 1928 until December 31, 1997 is contained in Appendix B.

         In presenting investment results, the Fund may also include references
to certain financial planning concepts, including (a) an investor's need to
evaluate his financial assets and obligations to determine how much to invest;
(b) his need to analyze the objectives of various investments to determine where
to invest; and (c) his need to analyze his time frame for future capital needs
to determine how long to invest. The investor controls these three factors, all
of which affect the use of investments in building assets.

AUTOMATED INFORMATION LINE

         FactFoneSM, Pioneer's 24-hour automated information line, allows
shareholders to dial toll-free 1-800-225-4321 and hear recorded fund
information, including:

         o        net asset value prices for all Pioneer mutual funds;

         o        annualized 30-day yields on Pioneer fixed income funds;


         o        annualized 7-day yields and 7-day effective (compound) yields
                  for Pioneer Cash Reserves Fund; and

         o        dividends and capital gains distributions for all Pioneer\
                  mutual funds.

         Yields are calculated in accordance with SEC mandated standard
formulas.

         In addition, by using a personal identification number ("PIN"),
shareholders may enter purchases, exchanges and redemptions, access their
account balances and last three transactions and may order a duplicate
statement. See "FactFoneSM" in the Prospectus for more information.

         All performance numbers communicated through FactFoneSM represent past
performance and include the applicable maximum sales charge. A shareholder's
actual yield and total return will vary with changing market conditions. The
value of Class A, Class B and Class C shares (except for Pioneer Cash Reserves
Fund, which seeks to maintain a stable $1.00 share price) will also vary and may
be worth more or less at redemption than their original cost.

                                   APPENDIX A

           DESCRIPTION OF SHORT-TERM DEBT AND CORPORATE BOND RATINGS1

MOODY'S INVESTORS SERVICE, INC ("MOODY'S"). SHORT-TERM PRIME RATING
SYSTEM - TAXABLE DEBT AND DEPOSITS GLOBALLY

Moody's short-term debt ratings are opinions of the ability of issuers to repay
punctually senior debt obligations. These obligations have an original maturity
not exceeding one year, unless explicitly noted.

Moody's employs the following three designations, all judged to be investment
grade, to indicate the relative repayment ability of rated issuers:

PRIME-1: Issuers rated Prime-1 (or supporting institutions) have a superior
ability for repayment of senior short-term debt obligations. Prime-1 repayment
ability will often be evidenced by many of the following characteristics:

         Leading market positions in well-established industries. High rates of
         return on funds employed.
         Conservative capitalization structure with moderate reliance on debt
         and ample asset protection.
         Broad margins in earnings coverage of fixed financial charges and
         high internal cash generation.
         Well-established access to a range of financial markets and assured
         sources of alternate liquidity.

PRIME-2: Issuers rated Prime-2 (or supporting institutions) have a strong
ability for repayment of senior short-term debt obligations. This will normally
be evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, may be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.

PRIME-3: Issuers rated Prime-3 (or supporting institutions) have an acceptable
ability for repayment of senior short-term obligations. The effect of industry
characteristics and market compositions may be more pronounced. Variability in
earnings and profitability may result in changes in the level of debt protection
measurements and may require relatively high financial leverage. Adequate
alternate liquidity is maintained.

NOT PRIME: Issuers rated Not Prime do not fall within any of the Prime rating
categories.

Obligations of a branch of a bank are considered to be domiciled in the country
in which the branch is located. Unless noted as an exception, Moody's rating on
a bank's ability to repay senior obligations extends only to branches located in
countries which carry a Moody's Sovereign Rating for Bank Deposits. Such branch
obligations are rated at the lower of the bank's rating or Moody's Sovereign
Rating for Bank Deposits for the country in which the branch is located.



- --------
1 The ratings indicated herein are believed to be the most recent ratings
available at the date of this Statement of Additional Information for the
securities listed. Ratings are generally given to securities at the time of
issuance. While the rating agencies may from time to time revise such ratings,
they undertake no obligation to do so, and the ratings indicated do not
necessarily represent ratings which will be given to these securities on the
date of the Fund's fiscal year-end.


                                       30


<PAGE>


When the currency in which an obligation is denominated is not the same as the
currency of the country in which the obligation is domiciled, Moody's ratings do
not incorporate an opinion as to whether payment of the obligation will be
affected by actions of the government controlling the currency of denomination.
In addition, risks associated with bilateral conflicts between an investor's
home country and either the issuer's home country or the country where an
issuer's branch is located are not incorporated into Moody's short-term debt
ratings.

If an issuer represents to Moody's that its short-term debt obligations are
supported by the credit of another entity or entities, then the name or names of
such supporting entity or entities are listed within the parenthesis beneath the
name of the issuer, or there is a footnote referring the reader to another page
for the name or names of the supporting entity or entities. In assigning ratings
to such issuers, Moody's evaluates the financial strength of the affiliated
corporations, commercial banks, insurance companies, foreign governments or
other entities, but only as one factor in the total rating assessment.

MOODY'S CORPORATE BOND RATINGS

AAA: Bonds which are rated Aaa are judged to be of the best quality. They carry
the smallest degree of investment risk and are generally referred to as "gilt
edge." Interest payments are protected by a large or by an exceptionally stable
margin and principal is secure. While the various protective elements are likely
to change, such changes as can be visualized are most unlikely to impair the
fundamentally strong position of such issues.

AA: Bonds which are rated Aa are judged to be of high quality by all standards.
Together with the Aaa group they comprise what are generally known as high grade
bonds. They are rated lower than the best bonds because margins of protection
may not be as large as in Aaa securities or fluctuation of protective elements
may be of greater amplitude or there may be other elements present which make
the long term risks appear somewhat larger than in Aaa securities.

A: Bonds which are rated A possess many favorable investment attributes and are
to be considered as upper-medium-grade obligations. Factors giving security to
principal and interest are considered adequate, but elements may be present
which suggest a susceptibility to impairment sometime in the future.

BAA: Bonds which are rated Baa are considered as medium-grade obligations (i.e.,
they are neither highly protected nor poorly secured). Interest payments and
principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.

BA: Bonds which are rated Ba are judged to have speculative elements; their
future cannot be considered as well assured. Often the protection of interest
and principal payments may be very moderate and thereby not well safeguarded
during both good and bad times over the future. Uncertainty of position
characterizes bonds in this class.

B: Bonds which are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.

CAA: Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.

                                       31


<PAGE>


CA: Bonds which are rated Ca represent obligations which are speculative in a
high degree. Such issues are often in default or have other marked shortcomings.

C: Bonds which are rated C are the lowest rated class of bonds, and issues so
rated can be regarded as having extremely poor prospects of ever attaining any
real investment standing.

NOTE: Moody's applies numerical modifiers 1, 2 and 3 in each generic rating
classification from Aa through Caa. The modifier 1 indicated that the obligation
ranks in the higher end of its generic rating category; the modifier 2 indicated
a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of
that generic rating category.

STANDARD & POOR'S SHORT-TERM ISSUE CREDIT RATINGS

A-1: A short-term obligation rated A-1 is rated in the highest category by
Standard & Poor's. The obligor's capacity to meet its financial commitment on
the obligation is strong. Within this category, certain obligations are
designated with a plus sign (+). This indicates that the obligor's capacity to
meet its financial commitment on these obligations is extremely strong.

A-2: A short-term obligation rated A-2 is somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions than
obligations in higher rating categories. However, the obligor's capacity to meet
its financial commitment on the obligation is satisfactory.

A-3: A short-term obligation rated A-3 exhibits adequate protection parameters.
However, adverse economic conditions or changing circumstances are more likely
to lead to a weakened capacity of the obligor to meet its financial commitment
on the obligation.

B: A short-term obligation rated B is regarded as having significant speculative
characteristics. The obligor currently has the capacity to meet its financial
commitment on the obligation; however, it faces major ongoing uncertainties
which could lead to the obligor's inadequate capacity to meet its financial
commitment on the obligation.

C: A short-term obligation rated C is currently vulnerable to nonpayment and is
dependent upon favorable business, financial, and economic conditions for the
obligor to meet its financial commitment on the obligation.

D: A short-term obligation rated D is in payment default. The D rating category
is used when payments on an obligation are not made on the date due even if the
applicable grace period has not expired, unless Standard & Poor's believes that
such payments will be made during such grace period. The D rating also will be
used upon the filing of a bankruptcy petition or the taking of a similar action
if payments on an obligation are jeopardized.

STANDARD & POOR'S CORPORATE BOND RATINGS

AAA: An obligation rated AAA has the highest rating assigned by Standard &
Poor's. The obligor's capacity to meet its financial commitment on the
obligation is extremely strong.

AA: An obligation rated AA differs from the highest-rated obligations only in a
small degree. The obligor's capacity to meet its financial commitment on the
obligation is very strong.


                                       32


<PAGE>


A: An obligation rated A is somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions than obligations in
higher-rated categories. However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.

BBB: An obligation rated BBB exhibits adequate protection parameters. However,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened capacity of the obligor to meet its financial commitment on the
obligation.

Obligations rated BB, B, CCC, CC, and C are regarded as having significant
speculative characteristics. BB indicates the least degree of speculation and C
the highest. While such obligations will likely have some quality and protective
characteristics, these may be outweighed by large uncertainties or major
exposures to adverse conditions.

BB: An obligation rated BB is less vulnerable to nonpayment than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse business, financial or economic conditions which could lead to the
obligor's capacity to meet its financial commitment on the obligation.

B: An obligation rated B is more vulnerable to nonpayment than obligations rated
BB, but the obligor currently has the capacity to meet its financial commitment
on the obligation. Adverse business, financial, or economic conditions will
likely impair the obligor's capacity or willingness to meet its financial
commitment on the obligation.

CCC: An obligation rated CCC is currently vulnerable to nonpayment and is
dependent upon favorable business, financial and economic conditions for the
obligor to meet its financial commitment on the obligation. In the event of
adverse business, financial or economic conditions, the obligor is not likely to
have the capacity to meet its financial commitment on the obligation.

CC: An obligation rated CC is currently highly vulnerable to nonpayment.

C: The C rating may be used to cover a situation where a bankruptcy petition has
been filed or similar action has been taken, but payments on this obligation are
being continued.

D: An obligation rated D is in payment default. The D rating category is used
when payments on an obligation are not made on the date due even if the
applicable grace period has not expired, unless Standard & Poor's believes that
such payments will be made during such grace period. The D rating also will be
used upon the filing of a bankruptcy petition or the taking of a similar action
if payments are jeopardized.

PLUS (+) OR MINUS (-): The rating from AA to CCC may be modified by the addition
of a plus or minus sign to show relative standing within the major categories.

R: This symbol is attached to the ratings of instruments with significant
noncredit risks. It highlights risks to principal or volatility of expected
returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities;
obligations exposed to severe prepayment risk, such as interest-only or
principal-only mortgage securities; and obligations with unusually risky
interest terms, such as inverse floaters.

                               INDEX DESCRIPTIONS


The following securities indices are well known, unmanaged measures of market
performance. Advertisements and sales literature for the Fund may refer to these
indices or may present comparisons between the performance of the Fund and one
or more of the indices. Other indices may also be used, if appropriate. The
indices are not available for direct investment. The data presented are not
meant to be indicative of the performance of the Fund, do not reflect past
performance and do not guarantee future results.

S&P 500
This index is a readily available, carefully constructed, market value weighted
benchmark of common stock performance. Currently, the S&P 500 includes 500 of
the largest stocks (in terms of stock market value) in the U.S.

DOW JONES INDUSTRIAL AVERAGE
This is a total return index based on the performance of stocks of 30 blue chip
companies widely held by individuals and institutional investors. The 30 stocks
represent about a fifth of the $8 trillion-plus market value of all U.S. stocks
and about a fourth of the value of stocks listed on the New York Stock Exchange
(NYSE).

U.S. SMALL STOCK INDEX
This index is a market value weighted index of the ninth and tenth deciles of
the NYSE, plus stocks listed on the American Stock Exchange and over the counter
with the same or less capitalization as the upper bound of the NYSE ninth
decile.

U.S. INFLATION
THE CONSUMER PRICE INDEX FOR ALL URBAN CONSUMERS (CPI-U), not seasonally
adjusted, is used to measure inflation, which is the rate of change of consumer
goods prices. Unfortunately, the inflation rate as derived by the CPI is not
measured over the same period as the other asset returns. All of the security
returns are measured from one month-end to the next month-end. CPI commodity
prices are collected during the month. Thus, measured inflation rates lag the
other series by about one-half month. Prior to January 1978, the CPI (as
compared with CPI-U) was used. Both inflation measures are constructed by the
U.S. Department of Labor, Bureau of Labor Statistics, Washington, DC.

S&P/BARRA INDEXES
The S&P/BARRA GROWTH AND VALUE INDEXES are constructed by dividing the stocks in
the S&P 500 according to price-to-book ratios. The GROWTH INDEX contains stocks
with higher price-to-book ratios, and the VALUE INDEX contains stocks with lower
price-to-book ratios. Both indexes are market capitalization weighted.

MERRILL LYNCH MICRO-CAP INDEX
The MERRILL LYNCH MICRO-CAP INDEX represents the performance of 2,036 stocks
ranging in market capitalization from $50 million to $220 million. Index returns
are calculated monthly.

LONG-TERM U.S. GOVERNMENT BONDS
The total returns on long-term government bonds after 1977 are constructed with
data from The Wall Street Journal and are calculated as the change in the flat
price or and-interest price. From 1926 to 1976, data are obtained from the
government bond file at the Center for Research in Security Prices (CRSP),
Graduate School of Business, University of Chicago. Each year, a one-bond
portfolio with a term of approximately 20 years and a reasonably current coupon
was used and whose returns did not reflect potential tax benefits, impaired
negotiability or special redemption or call privileges. Where callable bonds had
to be used, the term of the bond was assumed to be a simple average of the
maturity and first call dates minus the current date. The bond was "held" for
the calendar year and returns were computed.

INTERMEDIATE-TERM U.S. GOVERNMENT BONDS
Total returns of intermediate-term government bonds after 1987 are calculated
from The Wall Street Journal prices, using the change in flat price. Returns
from 1934 to 1986 are obtained from the CRSP government bond file.

Each year, one-bond portfolios are formed, the bond chosen is the shortest
noncallable bond with a maturity not less than five years, and this bond is
"held" for the calendar year. Monthly returns are computed. (Bonds with impaired
negotiability or special redemption privileges are omitted, as are partially or
fully tax-exempt bonds starting with 1943.) From 1934 to 1942, almost all bonds
with maturities near five years were partially or fully tax-exempt and were
selected using the rules described above. Personal tax rates were generally low
in that period, so that yields on tax-exempt bonds were similar to yields on
taxable bonds. From 1926 to 1933, there are few bonds suitable for construction
of a series with a five-year maturity. For this period, five-year bond yield
estimates are used.

MORGAN STANLEY CAPITAL INTERNATIONAL ("MSCI")
MSCI's international indices are based on the share prices of approximately
1,700 companies listed on stock exchanges in the 22 countries that make up the
MSCI World Index. MSCI's emerging market indices are comprised of approximately
1000 stocks from 26 countries.

Countries in the MSCI EAFE INDEX are: Australia, Austria, Belgium, Denmark,
Finland, France, Germany, Hong Kong, Ireland, Italy, Japan, Malaysia,
Netherlands, New Zealand, Norway, Singapore, Spain, Sweden, Switzerland and
United Kingdom.

Countries in the MSCI EMERGING MARKETS FREE INDEX are: Argentina, Brazil, Chile,
China Free, Czech Republic, Colombia, Greece, Hungary, India, Indonesia Free,
Israel, Jordan, Korea (at 50%), Malaysia Free, Mexico Free, Pakistan, Peru,
Philippines Free, Poland, Portugal, South Africa, Sri Lanka, Taiwan (at 50%),
Thailand Free, Turkey and Venezuela.

6-MONTH CDS
Data sources include the Federal Reserve Bulletin and The Wall Street Journal.

LONG-TERM U.S. CORPORATE BONDS
Since 1969, corporate bond total returns are represented by the Salomon Brothers
Long-Term High-Grade Corporate Bond Index. As most large corporate bond
transactions take place over the counter, a major dealer is the natural source
of these data. The index includes nearly all Aaa- and Aa-rated bonds with at
least 10 years to maturity. If a bond is downgraded during a particular month,
its return for the month is included in the index before removing the bond from
future portfolios.

From 1926 to 1968 the total returns were calculated by summing the capital
appreciation returns and the income returns. For the period 1946 to 1968,
Ibbotson and Sinquefield backdated the Salomon Brothers'


                                       38


<PAGE>


index, using Salomon Brothers' monthly yield data with a methodology
similar to that used by Salomon Brothers for 1969 to 1995. Capital appreciation
returns were calculated from yields assuming (at the beginning of each monthly
holding period) a 20-year maturity, a bond price equal to par, and a coupon
equal to the beginning-of-period yield. For the period 1926 to 1945, Standard &
Poor's monthly high-grade corporate composite yield data were used, assuming a
4% coupon and a 20-year maturity. The conventional present-value formula for
bond price for the beginning and end-of-month prices was used. (This formula is
presented in Ross, Stephen A., and Westerfield, Randolph W., Corporate Finance,
Times Mirror/Mosby, St. Louis, 1990, p. 97 ["Level-Coupon Bonds"].) The monthly
income return was assumed to be one-twelfth the coupon.

U.S. (30-DAY) TREASURY BILLS
For the U.S. TREASURY BILL INDEX, data from The Wall Street Journal are used
after 1977; the CRSP government bond file is the source until 1976. Each month a
one-bill portfolio containing the shortest-term bill having not less than one
month to maturity is constructed. (The bill's original term to maturity is not
relevant.) To measure holding period returns for the one-bill portfolio, the
bill is priced as of the last trading day of the previous month-end and as of
the last trading day of the current month.

NATIONAL ASSOCIATION OF REAL ESTATE INVESTMENT TRUSTS ("NAREIT")EQUITY REIT
INDEX
All of the data are based upon the last closing price of the month for all
tax-qualified REITs listed on the NYSE, AMEX and NASDAQ. The data are
market-value-weighted. Prior to 1987 REITs were added to the index the January
following their listing. Since 1987 newly formed or listed REITs are added to
the total shares outstanding figure in the month that the shares are issued.
Only common shares issued by the REIT are included in the index. The total
return calculation is based upon the weighting at the beginning of the period.
Only those REITs listed for the entire period are used in the total return
calculation. Dividends are included in the month based upon their payment date.
There is no smoothing of income. Liquidating dividends, whether full or partial,
are treated as income.

RUSSELL U.S. EQUITY INDEXES
The RUSSELL 3000(R) INDEX (the "Russell 3000") is comprised of the 3,000 largest
U.S. companies as determined by market capitalization representing approximately
98% of the U.S. equity market. The average market capitalization is
approximately $2.8 billion. The RUSSELL 2500TM INDEX measures performance of the
2,500 smallest companies in the Russell 3000. The average market capitalization
is approximately $733.4 million, and the largest company in the index has an
approximate market capitalization of $2.9 billion. The RUSSELL 2000(R) INDEX
measures performance of the 2,000 smallest stocks in the Russell 3000; the
largest company in the index has a market capitalization of approximately $1.1
billion. The RUSSELL 1000(R) INDEX (the "Russell 1000") measures the performance
of the 1,000 largest companies in the Russell 3000. The average market
capitalization is approximately $7.6 billion. The smallest company in the index
has an approximate market capitalization of $1.1 billion. The RUSSELL MIDCAPTM
Index measures performance of the 800 smallest companies in the Russell 1000.
The largest company in the index has an approximate market capitalization of
$8.0 billion.

The Russell indexes are reconstituted annually as of July 1, based on May 31

index of 120 publicly traded real estate securities, such as REITs, real estate
operating companies ("REOCs") and partnerships.

The index contains performance data on five major categories of property:
office, retail, industrial, apartment and miscellaneous. The companies in the
index are 91.66% equity and hybrid REITs and 8.33% REOCs.

STANDARD & POOR'S MIDCAP 400 INDEX
The S&P 400 is a market-capitalization-weighted index. The performance data for
the index were calculated by taking the stocks presently in the index and
tracking them backwards in time as long as there were prices reported. No
attempt was made to determine what stocks "might have been" in the S&P 400 five
or ten years ago had it existed. Dividends are reinvested on a monthly basis
prior to June 30, 1991, and are reinvested daily thereafter.

LIPPER BALANCED FUNDS INDEX
This index represents equally weighted performance, adjusted for capital gains
distributions and income dividends, of approximately 30 of the largest funds
with a primary objective of conserving principal by maintaining at all times a
balanced portfolio of stocks and bonds. Typically, the stock/bond ratio ranges
around 60%/40%.

BANK SAVINGS ACCOUNT
Data sources include the U.S. League of Savings Institutions Sourcebook; average
annual yield on savings deposits in FSLIC [FDIC] insured savings institutions
for the years 1963 to 1987; and The Wall Street Journal thereafter.
