INVESTMENT OBJECTIVE AND POLICIES 

[sidebar] 
The Fund's investment objective 
is to generate a high level of 
current income consistent 
with prudent investment risk. 

The Fund's investment objective is to generate a high level of current 
income, consistent with prudent investment risk, through investment in a 
diversified portfolio of freely marketable debt securities. The Fund's 
Adviser seeks high current income consistent with the moderate level of risk 
associated with a portfolio consisting primarily of investment grade debt 
securities. 

   
Under normal market conditions, at least 65% of the value of the Fund's 
assets will be in bonds and/or debentures. In addition, the Fund contemplates 
that at least 75% of the value of its total investments in debt securities 
(other than commercial paper) will be represented by those securities that 
have, at the time of purchase, a rating within the four highest grades as 
determined by Moody's Investors Service, Inc. ("Moody's") (Aaa, Aa, A or Baa) 
or Standard & Poor's Ratings Group ("S&P") (AAA, AA, A, or BBB) and debt 
securities of banks, the U.S. Government and its agencies or 
instrumentalities and other issuers which, although not rated as a matter of 
policy by either Moody's or S&P, are considered by the Fund to have 
investment quality comparable to securities receiving ratings within the four 
highest grades. Debt securities rated Baa or BBB are considered medium-grade 
obligations with speculative characteristics and adverse economic conditions 
or changing circumstances may weaken the issuers' capacity to pay interest 
and repay principal. The Fund will diversify its investments among a number 
of industry groups without concentration in any particular industry. The 
Fund's investments, and consequently its net asset value, will be subject to 
the market fluctuations and risks inherent in all securities. There is no 
assurance that the Fund will achieve its investment objective. 
    

Securities of domestic and foreign issuers. The Fund may invest in U.S. 
dollar-denominated securities of foreign and United States issuers that are 
issued in or outside of the U.S. Foreign companies may not be subject to 
accounting standards and government supervision comparable to U.S. companies, 
and there is often less publicly available information about their 
operations. Foreign markets generally provide less liquidity than U.S. 
markets (and thus potentially greater price volatility) and typically provide 
fewer regulatory protections for investors. Foreign securities can also be 
affected by political or financial instability abroad. It is anticipated that 
under normal conditions, the Fund will not invest more than 25% of its total 
assets in foreign securities (excluding U.S. dollar-denominated Canadian 
securities). 

Mortgage-Backed and Derivative Securities 

Mortgage-backed securities represent participation interests in pools of 
adjustable and fixed mortgage loans which are guaranteed by agencies or 
instrumentalities of the U.S. Government. Unlike conventional debt 
obligations, mortgage-backed securities provide monthly payments derived from 
the monthly interest and principal payments (including any prepayments) made 
by the individual borrowers on the pooled mortgage loans. The mortgage loans 
underlying mortgage-backed securities are generally subject to a greater rate 
of principal prepayments in a declining interest rate environment and to a 
lesser rate of principal prepayments in an increasing interest rate 
environment. Under certain interest and prepayment rate scenarios, the Fund 
may fail to recover the full amount of its investment in mortgage-backed 
securities 

                                      5 
<PAGE>
 
notwithstanding any direct or indirect governmental or agency guarantee. 
Since faster than expected prepayments must usually be invested in lower 
yielding securities, mortgage-backed securities are less effective than 
conventional bonds in "locking in" a specified interest rate. In a rising 
interest rate environment, a declining prepayment rate may extend the average 
life of many mortgage-backed securities. Extending the average life of a 
mortgage-backed security increases the risk of depreciation due to future 
increases in market interest rates. 

The Fund's investments in mortgage-backed securities may include conventional 
mortgage passthrough securities and certain classes of multiple class 
collateralized mortgage obligations ("CMOs"). In order to reduce the risk of 
prepayment for investors, CMOs are issued in multiple classes, each having 
different maturities, interest rates, payment schedules and allocations of 
principal and interest on the underlying mortgages. Senior CMO classes will 
typically have priority over residual CMO classes as to the receipt of 
principal and/or interest payments on the underlying mortgages. The CMO 
classes in which the Fund may invest include but are not limited to 
sequential and parallel pay CMOs, including planned amortization class 
("PAC") and target amortization class ("TAC") securities. 

Risks of Mortgage-Backed Securities. Different types of mortgage-backed 
securities are subject to different combinations of prepayment, extension, 
interest rate and/or other market risks. Conventional mortgage passthrough 
securities and sequential pay CMOs are subject to all of these risks, but are 
typically not leveraged. PACs, TACs and other senior classes of sequential 
and parallel pay CMOs involve less exposure to prepayment, extension and 
interest rate risk than other mortgage-backed securities, provided that 
prepayment rates remain within expected prepayment ranges or "collars." 

[sidebar] 
The Fund may invest in 
structured debt obligations 
indexed to various financial 
assets or rates. 

Structured Securities. The Fund may invest in structured notes, bonds or 
debentures, the value of the principal of and/or interest on which is to be 
determined by reference to changes in the value of specific currencies, 
interest rates, commodities, indices or other financial indicators (the 
"Reference") or the relative change in two or more References. The interest 
rate or the principal amount payable upon maturity or redemption may be 
increased or decreased depending upon changes in the applicable Reference. 
The terms of the structured securities may provide that in certain 
circumstances no principal is due at maturity and, therefore, may result in 
the loss of the Fund's investment. Structured securities may be positively or 
negatively indexed, so that appreciation of the Reference may produce an 
increase or decrease in the interest rate or value of the security at 
maturity. In addition, the change in interest rate or the value of the 
security at maturity may be a multiple of the change in the value of the 
Reference. Consequently, structured securities entail a greater degree of 
market risk than other types of debt obligations. Structured securities may 
also be more volatile, less liquid and more difficult to accurately price 
than less complex fixed income investments. 

Futures and Option Contracts. The Fund may engage in transactions in futures 
contracts and options on futures contracts for hedging and speculative 
purposes. The Fund's ability to hedge successfully will depend on the ability 
of John Hancock Advisers, Inc. (the "Adviser") to predict accurately the 
future direction of interest rate changes, the degree of correlation between 
the futures and securities markets and other market fac- 

                                      6 
<PAGE>
 
tors. There is no assurance that a liquid market for futures and options will 
always exist. In addition, the Fund could be prevented from opening, or 
realizing the benefits of closing out, a futures or options position because 
of position limits or limits on daily price fluctuations imposed by an 
exchange. 

All of the Fund's futures contracts and options on futures contracts will be 
traded on a U.S. or foreign commodity exchange or board of trade. The Fund 
will not engage in a transaction in futures or options on futures for 
speculative purposes if, immediately thereafter, the sum of initial margin 
deposits and premiums required to establish speculative positions in futures 
contracts and options on futures exceeds 5% of the Fund's net assets. 

Lower-Rated Securities. The Fund may invest up to 25% of the value of its 
total assets in fixed income securities rated below Baa by Moody's, or below 
BBB by S&P, or in securities which are unrated. The Fund may invest in 
securities rated as low as Ca by Moody's or CC by S&P, which may indicate 
that the obligations are highly speculative and in default. Lower rated 
securities are generally referred to as junk bonds. See the Appendix attached 
to this Prospectus and the Statement of Additional Information, respectively, 
for the distribution of securities in the various ratings categories and a 
description of the characteristics of the categories. The Fund is not 
obligated to dispose of securities whose issuers subsequently are in default 
or which are downgraded below the above-stated ratings. The Fund may invest 
in unrated securities which, in the opinion of the Adviser, offer comparable 
yields and risks to those securities which are rated. 

Debt obligations rated in the lower ratings categories, or which are unrated, 
involve greater volatility of price and risk of loss of principal and income. 
In addition, lower ratings reflect a greater possibility of an adverse change 
in financial condition affecting the ability of the issuer to make payments 
of interest and principal. 

The market price and liquidity of lower rated fixed income securities 
generally respond to short-term economic, corporate and market developments 
to a greater extent than do higher rated securities. In the case of 
lower-rated securities, these developments are perceived to have a more 
direct relationship to the ability of an issuer of lower rated securities to 
meet its ongoing debt obligations. 

Reduced volume and liquidity in the high yield bond market, or the reduced 
availability of market quotations, will make it more difficult to dispose of 
the bonds and value accurately the Fund's assets. The reduced availability of 
reliable, objective data may increase the Fund's reliance on management's 
judgment in valuing the high yield bonds. To the extent that the Fund invests 
in these securities, the achievement of the Fund's objective will depend more 
on the Adviser's judgment and analysis than would otherwise be the case. In 
addition, the Fund's investments in high yield securities may be susceptible 
to adverse publicity and investor perceptions, whether or not the perceptions 
are justified by fundamental factors. In the past, economic downturns and 
increases in interest rates have caused a higher incidence of default by the 
issuers of lower-rated securities and may do so in the future, particularly 
with respect to highly leveraged issuers. The market prices of zero coupon 
and payment-in-kind bonds are affected to a greater extent by interest rate 
changes, and thereby tend to 

                                      7 
<PAGE>
 
be more volatile than securities that pay interest periodically and in cash. 
Increasing rate note securities are typically refinanced by the issuers 
within a short period of time. The Fund accrues income on these securities 
for tax and accounting purposes, which is required to be distributed to 
shareholders. Because no cash is received while income accrues on these 
securities, the Fund may be forced to liquidate other investments to make the 
distributions. 

The Fund may acquire individual securities of any maturity and is not subject 
to any limits as to the average maturity of its overall portfolio. The longer 
the Fund's average portfolio maturity, the more the value of the portfolio 
and the net asset value of the Fund's shares will fluctuate in response to 
changes in interest rates. An increase in interest rates will generally 
reduce the value of the Fund's portfolio securities and the Fund's shares, 
while a decline in interest rates will generally increase their value. 

Restricted Securities. The Fund may purchase restricted securities, including 
those eligible for resale to "qualified institutional buyers" pursuant to 
Rule 144A under the Securities Act of 1933 (the "Securities Act"). The 
Trustees will monitor the Fund's investments in these securities, focusing on 
certain factors, including valuation, liquidity and availability of 
information. Purchases of other restricted securities are subject to an 
investment restriction limiting all the Fund's illiquid securities to not 
more than 15% of its net assets. 

   
Lending of Securities. The Fund may lend portfolio securities to brokers, 
dealers, and financial institutions if the loan is collateralized by cash or 
U.S. Government securities according to applicable regulatory requirements. 
The Fund may reinvest any cash collateral in short-term securities and 
interests in money market funds. When the Fund lends portfolio securities, 
there is a risk that the borrower may fail to return the loaned securities. 
As a result, the Fund may incur a loss or in the event of the borrower's 
bankruptcy may be delayed in or prevented from liquidating the collateral. It 
is a fundamental policy of the Fund not to lend portfolio securities having a 
total value in excess of 33-1/3% of its total assets. 
    

   
Repurchase Agreements, Forward Commitments and When-Issued Securities. The 
Fund may enter into repurchase agreements and may purchase securities on a 
forward or when-issued basis. In a repurchase agreement, the Fund buys a 
security subject to the right and obligation to sell it back to the issuer at 
a higher price. These transactions must be fully collateralized at all times, 
but involve some credit risk to the Fund if the other party defaults on its 
obligation and the Fund is delayed in or prevented from liquidating the 
collateral. The Fund will segregate in a separate account cash or liquid, 
high grade debt securities equal in value to its forward commitments and 
when-issued securities. Purchasing securities for future delivery or on a 
when-issued basis may increase the Fund's overall investment exposure and 
involves a risk of loss if the value of the securities declines before the 
settlement date. 
    

Short-term Trading. Short-term trading means the purchase and subsequent sale 
of a security after it has been held for a relatively brief period of time. 
The Fund engages in short-term trading in response to changes in interest 
rates or other economic trends and developments, or to realize capital gain 
or improve income by taking advantage of yield disparities between various 
fixed-income securities. 

                                      8 
<PAGE>
 
   
Investment Restrictions. The Fund has adopted certain investment restrictions 
that are detailed in the Statement of Additional Information where they are 
designated as fundamental or nonfundamental. The investment objective and 
fundamental investment restrictions may not be changed without shareholder 
approval. All other investment policies and restrictions are nonfundamental 
and can be changed by a vote of the Trustees without shareholder approval. 
Portfolio turnover rates of the Fund for recent years are shown in the 
section "The Fund's Financial Highlights." 
    

   
[sidebar] 
Brokers are chosen on best 
price and execution. 
    

   
When choosing brokerage firms to carry out the Fund's transactions, the 
Adviser gives primary consideration to execution at the most favorable 
prices, taking into account the broker's professional ability and quality of 
service. Consideration may also be given to the broker's sale of Fund shares. 
Pursuant to procedures established by the Trustees, the Adviser may place 
securities transactions with brokers affiliated with the Adviser. These 
brokers include Tucker Anthony Incorporated, John Hancock Distributors, Inc. 
and Sutro & Company, Inc. They are indirectly owned by John Hancock Mutual 
Life Insurance Company, (the "Life Company") which in turn indirectly owns 
the Adviser. 
    

ORGANIZATION AND MANAGEMENT OF THE FUND 

[sidebar] 
The Trustees elect officers and 
retain the investment adviser 
who is responsible for the day- 
to-day operations of the Fund, 
subject to the Trustees' policies 
and supervision. 

   
The Fund is a diversified open-end management investment company organized as 
a Maryland corporation in 1973 and reorganized as a Massachusetts business 
trust in 1984. The Fund has an unlimited number of authorized shares of 
beneficial interest. The Fund's Declaration of Trust permits the Trustees, 
without shareholder approval, to create and classify shares of beneficial 
interest into separate series of the Fund. As of the date of this Prospectus, 
the Trustees have not authorized the creation of any new series of the Fund. 
Additional series may be added in the future. The Trust's Declaration of 
Trust also permits the Trustees to classify and reclassify any series or 
portfolio of shares into one or more classes. Accordingly, the Trustees have 
authorized the issuance of two classes of the Fund, designated Class A and 
Class B. The shares of each class represent an interest in the same portfolio 
of investments of the Fund and have equal rights as to voting, redemption, 
dividends and liquidation. However, each class bears different distribution 
fees, and Class A and Class B shareholders have exclusive voting rights with 
respect to their distribution plans. 
    

   
Shareholders have certain rights to remove Trustees. The Fund is not required 
to hold annual shareholder meetings, although special meetings may be held 
for such purposes as electing or removing Trustees, changing fundamental 
investment restrictions or approving a management contract. The Fund, under 
certain circumstances, will assist in shareholder communications with other 
shareholders. 
    

   
[sidebar] 
John Hancock Advisers, Inc. 
advises investment companies 
having a total asset value of 
more than $16 billion. 
    

   
The Adviser was organized in 1968 and is a wholly-owned indirect subsidiary 
of the Life Company, a financial services company. The Adviser provides the 
Fund, and other investment companies in the John Hancock group of funds, with 
investment research and portfolio management services. John Hancock Funds, 
Inc. ("John Hancock Funds"), an indirect subsidiary of the Life Company, 
distributes shares for all of the John Hancock funds through selected 
broker-dealers ("Selling Brokers"). Certain Fund officers are also officers 
of the Adviser and John Hancock Funds. Pursuant to an order granted by the 
Securities and Exchange Commission, the Fund has adopted 
    


                                      9 
<PAGE>

a deferred compensation plan for its independent Trustees which allows 
Trustees' fees to be invested by the Fund in other John Hancock funds. 

   
James Ho is primarily responsible for the management of the Fund. Mr. Ho is 
assisted by a team of portfolio managers and analysts. Mr. Ho also directs 
all taxable fixed-income investment management for the Adviser and has been 
associated with the Adviser since 1985. 
    

   
In order to avoid conflicts with portfolio trades for the Fund, the Adviser 
and the Fund have adopted extensive restrictions on personal securities 
trading by personnel of the Adviser and its affiliates. Some of these 
restrictions are: pre-clearance for all personal trades and a ban on the 
purchase of initial public offerings, as well as contributions to specified 
charities of profits on securities held for less than 91 days. These 
restrictions are a continuation of the basic principle that the interests of 
the Fund and its shareholders come first. 
    

ALTERNATIVE PURCHASE ARRANGEMENTS 

   
[sidebar] 
An alternative purchase plan 
allows you to choose the 
method of payment that is 
best for you. 
    

   
You can purchase shares of the Fund at a price equal to their net asset value 
per share, plus a sales charge. At your election, this charge may be imposed 
either at the time of the purchase (see "Initial Sales Charge 
Alternative--Class A Shares") or on a contingent deferred basis (see 
"Contingent Deferred Sales Charge Alternative--Class B Shares"). If you do 
not specify on your account application the class of shares you are 
purchasing, it will be assumed that you are investing in Class A shares. 
    

[sidebar] 
Investments in Class A 
shares are subject to an 
initial sales charge. 

   
Class A Shares. If you elect to purchase Class A shares, you will incur an 
initial sales charge unless the amount you purchase is $1 million or more. If 
you purchase $1 million or more of Class A shares you will not be subject to 
an initial sales charge, but you will incur a sales charge if you redeem your 
shares within one year of purchase. Class A shares are subject to ongoing 
distribution and service fees at a combined annual rate of up to 0.30% of the 
Fund's average daily net assets attributable to the Class A shares. Certain 
purchases of Class A shares qualify for reduced initial sales charges. See 
"Share Price--Qualifying for a Reduced Sales Charge." 
    

[sidebar] 
Investments in Class B 
shares are subject to a 
contingent deferred sales 
charge. 

   
Class B Shares. You will not incur a sales charge when you purchase Class B 
shares, but the shares are subject to a sales charge if you redeem them 
within six years of purchase (the "contingent deferred sales charge" or the 
"CDSC"). Class B shares are subject to ongoing distribution and service fees 
at a combined annual rate of up to 1.00% of the Fund's average daily net 
assets attributable to the Class B shares. Investing in Class B shares 
permits all of your dollars to work from the time you make your investment, 
but the higher ongoing distribution fee will cause these shares to have 
higher expenses than Class A shares. To the extent that any dividends are 
paid by the Fund, these higher expenses will also result in lower dividends 
than those paid on Class A shares. 
    

   
Class B shares are not available to full-service defined contribution plans 
administered by Investor Services or the Life Company that had more than 100 
eligible employees at the inception of the Fund account. 
    

                                      10 
<PAGE>
 
Factors to Consider in Choosing an Alternative 

   
[sidebar] 
You should consider which 
class of shares will be more 
beneficial for you. 
    

   
The alternative purchase arrangement allows you to choose the most beneficial 
way to buy shares, given the amount of your purchase, the length of time you 
expect to hold your shares and other circumstances. You should consider 
whether, during the anticipated life of your Fund investment, the CDSC and 
the accumulated fees on Class B shares would be less than the initial sales 
charge and accumulated fees on Class A shares purchased at the same time, and 
to what extent this differential would be offset by the Class A shares' lower 
expenses. To help you make this determination, the table under the caption 
"Expense Information" on the inside cover page of this Prospectus shows 
examples of the charges applicable to each class of shares. Class A shares 
will normally be more beneficial if you qualify for a reduced sales charge. 
See "Share Price--Qualifying for a Reduced Sales Charge". 
    

Class A shares are subject to lower distribution and service fees and, 
accordingly, pay correspondingly higher dividends per share, to the extent 
any dividends are paid. However, because initial sales charges are deducted 
at the time of purchase, you would not have all of your funds invested 
initially and, therefore, would initially own fewer shares. If you do not 
qualify for reduced initial sales charges and expect to maintain your 
investment for an extended period of time, you might consider purchasing 
Class A shares. This is because the accumulated distribution and service 
charges on Class B shares may exceed the initial sales charge and accumulated 
distribution and service charges on Class A shares during the life of your 
investment. 

Alternatively, you might determine that it is more advantageous to purchase 
Class B shares to have all your funds invested initially. However you will be 
subject to higher distribution fees and, for a six-year period, a CDSC. 

   
In the case of Class A shares, distribution expenses that John Hancock Funds 
incurs in connection with the sale of shares will be paid from the proceeds 
of the initial sales charge and the ongoing distribution and service fees. In 
the case of Class B shares, the expenses will be paid from the proceeds of 
the ongoing distribution and service fees, as well as from the CDSC incurred 
upon redemption within six years of purchase. The purpose and function of the 
Class B shares' CDSC and ongoing distribution and service fees are the same 
as those of the Class A shares' initial sales charge and ongoing distribution 
and service fees. Sales personnel distributing the Fund's shares may receive 
different compensation for selling each class of shares. 
    

   
Dividends, if any, on Class A and Class B shares will be calculated in the 
same manner, at the same time and on the same day. They will also be in the 
same amount, except for differences resulting from each class bearing only 
its own distribution and service fees and shareholder meeting expenses. See 
"Dividends and Taxes." 
    

THE FUND'S EXPENSES 

   
For managing its investment and business affairs, the Fund pays a fee to the 
Adviser which for the 1995 fiscal year, was 0.50% of the Fund's average daily 
net asset value. 
    

[sidebar] 
The Fund pays distribution 
and service fees for marketing 
and sales-related shareholder 
servicing. 

   
The Class A and Class B shareholders have adopted distribution plans (each a 
"Plan") pursuant to Rule 12b-1 under the Investment Company Act of 1940 (the 
"1940 Act"). Under these Plans, the Fund will pay distribution and service 
fees at an aggregate annual rate of up to 0.30% of the Class A shares' 
average daily net assets and an aggregate annual 
    


                                      11 
<PAGE>
 
   
rate of up to 1.00% of the Class B shares' average daily net assets. In each 
case, up to 0.25% is for service expenses and the remaining amount is for 
distribution expenses. The distribution fees will be used to reimburse John 
Hancock Funds for its distribution expenses, including but not limited to: 
(i) initial and ongoing sales compensation to Selling Brokers and others 
(including affiliates of John Hancock Funds) engaged in the sale of Fund 
shares; (ii) marketing, promotional and overhead expenses incurred in 
connection with the distribution of Fund shares; and (iii) with respect to 
Class B shares only, interest expenses on unreimbursed distribution expenses. 
The service fees are paid to compensate Selling Brokers and others providing 
personal and account maintenance services to shareholders. 
    

   
In the event John Hancock Funds is not fully reimbursed for payments it makes 
or expenses it incurs under the Class A Plan, these expenses will not be 
carried beyond one year from the date they were incurred. These unreimbursed 
expenses under the Class B Plan will be carried forward together with 
interest on the balance of these unreimbursed expenses. 
    

   
For the fiscal year ended December 31, 1995 an aggregate of $2,970,686 of 
distribution expenses, or 4.64% of the average net assets of the Class B 
shares of the Fund, was not reimbursed or recovered by the John Hancock Funds 
through the receipt of deferred sales charges or 12b-1 fees in prior periods. 
    

   
The Fund compensates the Adviser for performing necessary tax and financial 
management services. The compensation for 1996 is estimated to be at an 
annual rate of 0.01875% of the average net assets of the Fund. 
    

Information on the Fund's total expenses is in the Fund's Financial 
Highlights section of this Prospectus. 

DIVIDENDS AND TAXES 

Dividends. Dividends from the Fund's net investment income are generally 
declared daily and distributed monthly. Capital gains, if any, are generally 
distributed annually. 

   
Dividends are reinvested in additional shares of your class unless you elect 
the option to receive cash. If you elect the cash option and the U.S. Postal 
Service cannot deliver your checks, your election will be converted to the 
reinvestment in additional shares option. Because of the higher expenses 
associated with Class B shares, any dividend on these shares will be lower 
than on the Class A shares. See "Share Price." 
    

   
Taxation. Dividends from the Fund's net investment income and net short-term 
capital gains are taxable to you as ordinary income. Dividends from the 
Fund's net long-term capital gains are taxable as long-term capital gains. 
These dividends are taxable whether received in cash or reinvested in 
additional shares. Certain dividends may be paid in January of a given year, 
but may be taxable as if you received them the previous December. The Fund 
will send you a statement by January 31 showing the tax status of the 
dividends you received for the prior year. 
    

The Fund has qualified and intends to continue to qualify as a regulated 
investment company under Subchapter M of the Internal Revenue Code of 1986, 
as amended (the "Code"). As a regulated investment company, the Fund will not 
be subject to Fed- 

                                      12 
<PAGE>
 
   
eral income taxes on any net investment income and net realized capital gains 
that are distributed to its shareholders within the time period prescribed by 
the Code. When you redeem (sell) or exchange shares, you may realize a 
taxable gain or loss. 
    

   
On the account application, you must certify that your social security or 
other taxpayer identification number you provide is correct and that you are 
not subject to backup withholding of Federal income tax. If you do not 
provide this information, or are otherwise subject to this withholding, the 
Fund may be required to withhold 31% of your dividends and the proceeds of 
redemptions and exchanges. 
    

   
In addition to Federal taxes, you may be subject to state, local or foreign 
taxes with respect to your investments in and distributions from the Fund. 
Non-U.S. shareholders and tax-exempt shareholders are subject to a different 
tax treatment not described above. In many states, a portion of the Fund's 
dividends that represent interest received by the Fund on direct U.S. 
Government obligations may be exempt from tax. You should consult your tax 
adviser for specific advice. 
    

PERFORMANCE 

[sidebar] 
The Fund may advertise its 
yield and total return. 

   
Yield reflects the Fund's rate of income on portfolio investments as a 
percentage of its share price. Yield is computed by annualizing the result of 
dividing the net investment income per share over a 30 day period by the 
maximum offering price per share on the last day of that period. Yield is 
calculated according to accounting methods that are standardized for all 
stock and bond funds. Because yield accounting methods differ from the 
methods used for other accounting purposes, the Fund's yield may not equal 
the income paid on your shares or the income reported in the Fund's financial 
statements. 
    

   
Total return shows the overall dollar or percentage change in value of a 
hypothetical investment in the Fund, assuming the reinvestment of all 
dividends. Cumulative total return shows the Fund's performance over a period 
of time. Average annual total return shows the cumulative return divided over 
the number of years included in the period. Because average annual total 
return tends to smooth out variations in the Fund's performance, you should 
recognize that it is not the same as actual year-to-year results. 
    

   
Both total return and yield calculations for Class A shares generally include 
the effect of paying the maximum sales charge (except as shown in "The Fund's 
Financial Highlights"). Investments at a lower sales charge would result in 
higher performance figures. Yield and total return for the Class B shares 
reflect the deduction of the applicable CDSC imposed on a redemption of 
shares held for the applicable period. All calculations assume that all 
dividends are reinvested at net asset value on the reinvestment dates during 
the periods. Total return and yield of Class A and Class B shares will be 
calculated separately and, because each class is subject to different 
expenses, the yield or total return with respect to each class for the same 
period may differ. The relative performance of the Class A and Class B shares 
will be affected by a variety of factors, including the higher operating 
expenses attributable to the Class B shares, whether the Fund's investment 
performance is better in the earlier or later portions of the period measured 
and the level of net assets of the classes during the period. The Fund will 
include the total return of both classes in any advertisement or promotional 
materials including the Fund's performance data. The value of the Fund's

shares, when redeemed, may be more or less than their original cost. Both 
total return and yield are historical calculations and are not an indication 
of future performance. See "Factors to Consider in Choosing an Alternative."

receives notification of the dollar equivalent from the Fund's custodian 
bank. Wire purchases normally take two or more hours to complete and, to be 
accepted the same day, must be received by 4:00 p.m., New York time. Your

reinvestment of dividends and automatic investment/withdrawal plans will be 
sent to you quarterly). A tax information statement will be mailed to you by 
January 31 of each year. 

SHARE PRICE 

[sidebar] 
The offering price of your 
shares is their net asset value 
plus a sales charge, if appli- 
cable, which will vary with 
the purchase alternative you 
choose. 

   
The net asset value per share ("NAV") is the value of one share. The NAV is 
calculated by dividing the net assets of each class by the number of 
outstanding shares of that class. The NAV of each class can differ. 
Securities in the Fund's portfolio are valued on the basis of market 
quotations, valuations provided by independent pricing services, or fair 
value as determined in good faith according to procedures approved by the 
Trustees. Short-term debt investments maturing within 60 days are valued at 
amortized cost, which the Board of Trustees has determined to approximate 
market value. Foreign securities are valued on the basis of quotations from 
the primary market in which they are traded. If quotations are not readily 
available, or the value has been materially affected by events occurring 
after the closing of a foreign market, assets are valued by a method that the 
Trustees believe accurately reflects fair value. The NAV is calculated once 
daily as of the close of regular trading on the New York Stock Exchange 
(generally at 4:00 P.M., New York time) on each day that the Exchange is 
open. 
    

Shares of the Fund are sold at the offering price based on the NAV computed 
after your investment request is received in good order by John Hancock 
Funds. If you buy shares of the Fund through a Selling Broker, the Selling 
Broker must receive your investment before the close of regular trading on 
the New York Stock Exchange, and transmit it to John Hancock Funds before its 
close of business, to receive that day's offering price.

Initial Sales Charge Alternative--Class A Shares. The offering price you pay 
for Class A shares of the Fund equals the NAV plus a sales charge as follows:

  (*) Upon notice to Selling Brokers with whom it has sales agreements, John 
      Hancock Funds may reallow an amount up to the full applicable sales 
      charge. A Selling Broker to whom substantially the entire sales charge is 
      reallowed may be deemed to be an underwriter under the Securities Act of 
      1933. 
    

   
 (**) No sales charge is payable at the time of purchase of Class A shares of 
      $1 million or more, but a CDSC may be imposed in the event of certain 
      redemption transactions within one year of purchase. 
    

(***) John Hancock Funds may pay a commission and first year's service fee 
      (as described in (+) below) to Selling Brokers who initiate and are 
      responsible for purchases of $1 million or more in aggregate, as 
      follows: 1% on sales to $4,999,999, 0.50% on the next $5 million and 
      0.25% on $10 million and over. 

  (+) At the time of sale, John Hancock Funds pays to Selling Brokers the first 
      year's service fee in advance, in an amount equal to 0.25% of the net 
      assets invested in the Fund. Thereafter it pays the service fee 
      periodically in arrears in an amount up to 0.25% of the Fund's average 
      annual net assets. Selling Brokers receive the fee as compensation for 
      providing personal and account maintenance services to shareholders. 

Sales charges ARE NOT APPLIED to any dividends that are reinvested in 
additional Class A shares of the Fund. 

John Hancock Funds will pay certain affiliated Selling Brokers at an annual 
rate of up to 0.05% of the daily net assets of the accounts attributable to 
these brokers. 

Under certain circumstances described below, investors in Class A shares may 
be entitled to pay reduced sales charges. See "Qualifying For a Reduced Sales 
Charge." 

   
Contingent Deferred Sales Charge--Investments of $1 Million or More in Class 
A Shares. Purchases of $1 million or more of the Fund's Class A shares will 
be made at net asset value with no initial sales charge, but if the shares 
are redeemed within 12 months after the end of the calendar month in which 
the purchase was made (the CDSC period), a CDSC will be imposed. The rate of 
the CDSC will depend on the amount invested as follows: 
    


            Amount Invested                 CDSC Rate 
 ---------------------------------------   ---------- 
$1 million to $4,999,999                      1.00% 
Next $5 million to $9,999,999                 0.50% 
Amounts of $10 million and over               0.25%

with at least 100 eligible employees at the inception of the Fund account, 
may purchase Class A shares with no initial sales charge. However, if the 
shares are redeemed within 12 months after the end of the calendar year in 
which the purchase was made, a CDSC will be imposed at the above rate. 
    

   
The CDSC will be assessed on an amount equal to the lesser of the current 
market value or the original purchase cost of the redeemed Class A shares. 
Accordingly, no CDSC will be imposed on increases in account value above the 
initial purchase price, including any dividends which have been reinvested in 
additional Class A shares. 
    

In determining whether a CDSC applies to a redemption, the calculation will 
be determined in a manner that results in the lowest possible rate being 
charged. Therefore, it will be assumed that the redemption is first made from 
any shares in your account that are not subject to the CDSC. The CDSC is 
waived on redemption in certain circumstances. See the discussion under 
"Waiver of Contingent Deferred Sales Charges." 

[sidebar] 
You may qualify for a 
reduced sales charge on 
your investments in 
Class A shares. 

   
Qualifying for a Reduced Sales Charge. If you invest more than $100,000 in 
Class A shares of the Fund or a combination of John Hancock funds (except 
money market funds), you may qualify for a reduced sales charge on your 
investments in Class A shares through a LETTER OF INTENTION. You may also be 
able to use the ACCUMULATION PRIVILEGE and COMBINATION PRIVILEGE to take 
advantage of the value of your previous investments in shares of the John 
Hancock funds in meeting the breakpoints for a reduced sales charge. For the 
ACCUMULATION PRIVILEGE and COMBINATION PRIVILEGE, the applicable sales charge 
will be based on the total of: 
    

1. Your current purchase of Class A shares of the Fund; 

2. The net asset value (at the close of business on the previous day) of (a) 
all Class A shares of the Fund you hold, and (b) all Class A shares of any 
other John Hancock funds you hold; and 

3. The net asset value of all shares held by another shareholder eligible to 
combine his or her holdings with you into a single "purchase." 

Example: 

   
If you hold Class A shares of a John Hancock fund with a net asset value of 
$80,000 and, subsequently, invest $20,000 in Class A shares of the Fund, the 
sales charge on this subsequent investment would be 3.75% and not 4.50%. This 
is the rate that would otherwise be applicable to investments of less than 
$100,000. See "Initial Sales Charge Alternative--Class A Shares." 
    

[sidebar] 
Class A shares may be avail- 
able without a sales charge 
to certain individuals and 
organizations. 

If you are in one of the following categories, you may purchase Class A 
shares of the Fund without paying a sales charge: 

(bullet) A Trustee or officer of the Trust; a Director or officer of the 
Adviser and its affiliates or Selling Brokers; employees or sales 
representatives of any of the foregoing; retired officers employees or 
Directors of any of the foregoing; a member of the immediate family of any of 
the foregoing; or any fund, pension, profit sharing or other benefit plan for 
the individuals described above. 

(bullet) Any state, county, city or any instrumentality, department, 
authority or agency of these entities that is prohibited by applicable 
investment laws from paying a sales charge or commission when it purchases 
shares of any registered investment management company.* 

                                      17 
<PAGE>
 
(bullet) A bank, trust company, credit union, savings institution or other 
type of depository institution, its trust departments or common trust funds 
if it is purchasing $1 million or more for non-discretionary customers or 
accounts.* 

   
(bullet) A broker, dealer, financial planner, consultant or registered 
investment adviser that has entered into an agreement with John Hancock Funds 
providing specifically for the use of Fund shares in fee-based investment 
products made available to their clients. 
    

   
(bullet) A former participant in an employee benefit plan with John Hancock 
funds, when he or she withdraws from his or her plan and transfers any or all 
of his or her plan distributions directly to the Fund. 
    

   
(bullet) A member of an approved affinity group financial services plan.* 
    

   
* For investments made under these provisions, John Hancock funds may make a 
payment out of its own resources to the Selling Broker in an amount not to 
exceed 0.25% of the amount invested. 
    

   
Class A shares of the Fund may also be purchased without an initial sales 
charge in connection with certain liquidation, merger or acquisition 
transactions involving other investment companies or personal holding 
companies. 
    

   
Contingent Deferred Sales Charge Alternative--Class B Shares. Class B shares 
are offered at net asset value per share without an initial sales charge, so 
that your entire investment will go to work at the time of purchase. However, 
Class B shares redeemed within six years of purchase will be subject to a 
CDSC at the rates set forth below. The charge will be assessed on an amount 
equal to the lesser of the current market value or the original purchase cost 
of the shares being redeemed. Accordingly, you will not be assessed a CDSC on 
increases in account value above the initial purchase price, including shares 
derived from dividend reinvestments. 
    

   
In determining whether a CDSC applies to a redemption, the calculation will 
be determined in a manner that results in the lowest possible rate being 
charged. It will be assumed that your redemption comes first from shares you 
have held beyond the six-year CDSC redemption period or those you acquired 
through dividend reinvestment and next from the shares you have held the 
longest during the six-year period. The CDSC is waived on redemptions in 
certain circumstances. See the discussion "Waiver of Contingent Deferred 
Sales Charges" below. 
    

Example: 

You have purchased 100 shares at $10 per share. The second year after your 
purchase, your investment's net asset value per share has increased by $2 to 
$12, and you have gained 10 additional shares through dividend reinvestment. 
If you redeem 50 shares at this time, your CDSC will be calculated as 
follows: 

<TABLE>
<CAPTION>
<S>        <C>                                                                              <C>
(bullet)   Proceeds of 50 shares redeemed at $12 per share                                  $ 600 
(bullet)   Minus proceeds of 10 shares not subject to CDSC because they were acquired 
           through dividend reinvestment (10 X $12)                                          -120 
(bullet)   Minus appreciation on remaining shares, also not subject to CDSC (40 X $2)         -80 
                                                                                              --- 
(bullet)   Amount subject to CDSC                                                           $ 400 
</TABLE>

                                      18 
<PAGE>
 
   
Proceeds from the CDSC are paid to John Hancock Funds. John Hancock Funds 
uses them to defray its expenses related to providing the Fund with 
distribution services in connection with the sale of the Class B shares, such 
as compensating selected Selling Brokers for selling these shares. The 
combination of the CDSC and the distribution and service fees makes it 
possible for the Fund to sell Class B shares without an initial sales charge. 
    

   
The amount of the CDSC, if any, will vary depending on the number of years 
from the time you purchase your Class B shares until the time you redeem 
them. Solely for determining this holding period, any payment you make during 
the month will be aggregated and deemed to have been made on the last day of 
the month.

Redeemed Following Purchase         Dollar Amount Subject to CDSC

Sixth                                            1.0% 
Seventh and thereafter                           None 


   
A commission equal to 3.75% of the amount invested and a first year's service 
fee equal to 0.25% of the amount invested are paid to Selling Brokers. The 
initial service fee is paid in advance at the time of sale for the provision 
of personal and account maintenance services to shareholders during the 
twelve months following the sale, and thereafter the service fee is paid in 
arrears. 
    

   
If you purchased Class B shares prior to January 1, 1994, the applicable CDSC 
as a percentage of the amount redeemed will be: 3% for redemptions during the 
third year after purchase, 2.5% for redemptions during the fourth year, 2% 
for redemptions during the fifth year, 1% for redemptions during the sixth 
year, and no CDSC for the seventh year and thereafter. 
    

   
[sidebar] 
Under certain circumstances, 
the CDSC on Class B and 
Class A share redemptions 
will be waived. 
    

   
Waiver of Contingent Deferred Sales Charge. The CDSC will be waived on 
redemptions of Class B shares and of Class A shares that are subject to a 
CDSC unless indicated otherwise, in the circumstances defined below: 
    

(bullet) Redemptions of Class B shares made under a Systematic Withdrawal 
Plan (see "How to Redeem Shares"), as long as your annual redemptions do not 
exceed 10% of your account value at the time you established your Systematic 
Withdrawal Plan and 10% of the value of your subsequent investments (less 
redemptions) in that account at the time you notify Investor Services. This 
waiver does not apply to Systematic Withdrawal Plan redemptions of Class A 
shares that are subject to a CDSC. 

(bullet) Redemptions made to effect distributions from an Individual 
Retirement Account either before or after age 59-1/2, as long as the 
distributions are based on your life expectancy or the joint-and-last 
survivor life expectancy of you and your beneficiary. These distributions 
must be free from penalty under the Code. 

(bullet) Redemptions made to effect mandatory distributions under the Code 
after age 70-1/2 from a tax-deferred retirement plan. 

                                      19 
<PAGE>
 
(bullet) Redemptions made to effect distributions to participants or 
beneficiaries from certain employer-sponsored retirement plans including 
those qualified under Section 401(a) of the Code, custodial accounts under 
Section 403(b)(7) of the Code and deferred compensation plans under Section 
457 of the Code. The waiver also applies to certain returns of excess 
contributions made to these plans. In all cases, the distributions must be 
free from penalty under the Code. 

(bullet) Redemptions due to death or disability. 

(bullet) Redemptions made under the Reinvestment Privilege, as described in 
"Additional Services and Programs" of this Prospectus. 

(bullet) Redemptions made pursuant to the Fund's right to liquidate your 
account if you own fewer than 50 shares. 

(bullet) Redemptions made in connection with certain liquidation, merger or 
acquisition transactions involving other investment companies or personal 
holding companies. 

(bullet) Redemptions from certain IRA and retirement plans that purchased 
shares prior to October 1, 1992. 

If you qualify for a CDSC waiver under one of these situations, you must 
notify Investor Services either directly or through your Selling Broker at 
the time you make your redemption. The waiver will be granted once Investor 
Services has confirmed that you are entitled to the waiver. 

   
Conversion of Class B Shares. Your Class B shares, and an appropriate portion 
of reinvested dividends on those shares will be converted into Class A shares 
automatically. This will occur no later than the month following eight years 
after the shares were purchased, and will result in lower annual distribution 
fees. If you exchanged Class B shares into this Fund from another John 
Hancock fund, the calculation will be based on the time you purchased the 
shares in the original fund. The Fund has been advised that the conversion of 
Class B shares into Class A shares of the Fund should not change your tax 
basis or tax holding period for the converted shares. 
    

HOW TO REDEEM SHARES 

   
You may redeem all or a portion of your shares on any business day. Your 
shares will be redeemed at the next NAV calculated after your redemption 
request is received in good order by Investor Services, less any applicable 
CDSC. The Fund may hold payment until reasonably satisfied that investments 
recently made by check or Invest-by-Phone have been collected (which may 
take up to 10 calendar days). 
    

   
Once your shares are redeemed, the Fund generally sends you payment on the 
next business day. When you redeem your shares, you may realize a taxable 
gain or loss, depending usually on the difference between what you paid for 
them and what you receive for them, subject to certain tax rules. Under 
unusual circumstances, the Fund may suspend redemptions or postpone payment 
for up to three business days or longer, as permitted by Federal securities 
laws.

To assure acceptance of your 
redemption request, please 
follow these procedures. 

By Telephone 

   
All Fund shareholders are eligible automatically for the telephone redemption 
privilege. Call 1-800-225-5291, from 8:00 A.M. to 4:00 P.M. (New York time), 
Monday through Friday, excluding days on which the New York Stock Exchange is 
closed. Investor Services employs the following procedures to confirm that 
instructions received by telephone are genuine. Your name, the account 
number, taxpayer identification number applicable to the account and other 
relevant information may be requested. In addition, telephone instructions 
are recorded. 
    

   
You may redeem up to $100,000 by telephone, but the address on the account 
must not have changed for the last 30 days. A check will be mailed to the 
exact name(s) and address shown on the account. 

If reasonable procedures, such as those described above, are not followed, 
the Fund may be liable for any loss due to unauthorized or fraudulent 
telephone instructions. In all other cases, neither the Fund nor Investor 
Services will be liable for any loss or expense for acting upon telephone 
instructions made according to the telephone transaction procedures mentioned 
above. 
    

   
Telephone redemption is not available for IRAs or other tax-qualified 
retirement plans or shares of the Fund that are in certificated form. 

During periods of extreme economic conditions or market changes, telephone 
requests may be difficult to implement due to a large volume of calls. During 
these times, you should consider placing redemption requests in writing or 
using EASI-Line. EASI-Line's telephone number is 1-800-338-8080. 
    

By Wire 

   
If you have a telephone redemption form on file with the Fund, redemption 
proceeds of $1,000 or more can be wired on the next business day to your 
designated bank account, and a fee (currently $4.00) will be deducted. You 
may also use electronic funds transfer to your assigned bank account, and the 
funds are usually collectible after two business days. Your bank may or may 
not charge for this service. Redemptions of less than $1,000 will be sent by 
check or electronic funds transfer. 

This feature may be elected by completing the "Telephone Redemption" section 
on the Account Privileges Application included with this Prospectus. 
    

In Writing 

Send a stock power or "letter of instruction" specifying the name of the 
Fund, the dollar amount or the number of shares to be redeemed, your name, 
class of shares, your account number and the additional requirements listed 
below that apply to your particular account.

Who may guarantee your 
signature 

A signature guarantee is a widely accepted way to protect you and the Fund by 
verifying the signature on your request. It may not be provided by a notary 
public. If the net asset value of the shares redeemed is $100,000 or less, 
John Hancock Funds may guarantee the signature. The following institutions 
may provide you with a signature guarantee, provided that the institution 
meets credit standards established by Investor Services: (i) a bank; (ii) a 
securities broker or dealer, including a government or municipal securities 
broker or dealer, that is a member of a clearing corporation or meets certain 
net capital requirements; (iii) a credit union having authority to issue 
signature guarantees; (iv) a savings and loan association, a building and 
loan association, a cooperative bank, a federal savings bank or association; 
or (v) a national securities exchange, a registered securities exchange or a 
clearing agency. 

Through Your Broker 

Your broker may be able to initiate the redemption. Contact your broker for 
instructions. 

[sidebar] 
Additional information 
about redemptions 

If you have certificates for your shares, you must submit them with your 
stock power or a letter of instruction. Unless you specify to the contrary, 
any outstanding Class A shares will be redeemed before Class B shares. You 
may not redeem certificated shares by telephone. 

Due to the proportionately high cost of maintaining smaller accounts, the 
Fund reserves the right to redeem at net asset value all shares in an account 
which holds fewer than 50 shares (except accounts under retirement plans) and 
to mail the proceeds to the shareholder, or the transfer agent may impose an 
annual fee of $10.00. No account will be involuntarily redeemed or additional 
fee imposed, if the value of the account is in excess of the Fund's minimum 
initial investment. No CDSC will be imposed on involuntary redemptions of 
shares. 
   
Shareholders will be notified before these redemptions are to be made or this 
fee is imposed, and will have 30 days to purchase additional shares to bring 
their account balance up to the required minimum. Unless the number of shares 
acquired by additional purchases and any dividend reinvestments exceeds the 
number of shares redeemed, repeated redemptions from a smaller account may 
eventually trigger this policy. 
    
ADDITIONAL SERVICES AND PROGRAMS 
   
[sidebar] 
You may exchange shares of 
the Fund for shares of the 
same class of another John 
Hancock fund. 
    
Exchange Privilege 

If your investment objective changes, or if you wish to achieve further 
diversification, John Hancock offers other funds with a wide range of 
investment goals. Contact your registered representative or Selling Broker 
and request a prospectus for the John Hancock fund that interests you. Read 
the prospectus carefully before exchanging your shares. You can exchange 
shares of each class of the Fund only for shares of the same class of another 
John Hancock fund. For this purpose, John Hancock funds with only one class 
of shares will be treated as Class A whether or not they have been so 
designated. 
   
Exchanges between funds that are not subject to a CDSC are based on their 
respective net asset values. No sales charge or transaction charge is 
imposed. Class B shares of the Fund that are subject to a CDSC may be 
exchanged into Class B shares of another John Hancock fund without incurring 
the CDSC; however these shares will be subject to the CDSC schedule of the 
shares acquired (except that exchanges into John Hancock Short-Term Strategic 
Income Fund, John Hancock Intermediate Maturity Government Fund and John 
Hancock Limited-Term Government Fund will be subject to the initial fund's 
CDSC). For purposes of computing the CDSC payable upon redemption of shares 
acquired in an exchange, the holding period of the original shares is added 
to the holding period of the shares acquired in an exchange. However if you 
exchange Class B shares purchased prior to January 1, 1994 for Class B shares 
of any other John Hancock fund, you will continue to be subject to the CDSC 
schedule in effect on your initial purchase date. 
    


                                      22 
<PAGE>
 
   
The Fund reserves the right to require that you keep previously exchanged 
shares (and reinvested dividends) in the Fund for 90 days before you are 
permitted a new exchange. The Fund may also terminate or alter the terms of 
the exchange privilege, upon 60 days' notice to shareholders. 
    

   
An exchange of shares is treated as a redemption of shares of one fund and 
the purchase of shares of another for Federal income tax purposes. An 
exchange may result in a taxable gain or loss. 
    

   
When you make an exchange, your account registration in both the existing and 
new account must be identical. The exchange privilege is available only in 
states where the exchange can be made legally. 
    

Under exchange agreements with John Hancock Funds, certain dealers, brokers 
and investment advisers may exchange their clients' Fund shares, subject to 
the terms of those agreements and John Hancock Funds' right to reject or 
suspend those exchanges at any time. Because of the restrictions and 
procedures under those agreements, the exchanges may be subject to timing 
limitations and other restrictions that do not apply to exchanges requested 
by shareholders directly, as described above. 

   
Because Fund performance and shareholders can be hurt by excessive trading, 
the Fund reserves the right to terminate the exchange privilege for any 
person or group that, in John Hancock Funds' judgment, is involved in a 
pattern of exchanges that coincide with a "market timing" strategy that may 
disrupt the Fund's ability to invest effectively according to its investment 
objective and policies, or might otherwise affect the Fund and its 
shareholders adversely. The Fund may also temporarily or permanently 
terminate the exchange privilege for any person who makes seven or more 
exchanges out of the Fund per calendar year. Accounts under common control or 
ownership will be aggregated for this purpose. Although the Fund will attempt 
to give prior notice whenever it is reasonably able to do so, it may impose 
these restrictions at any time. 
    

By Telephone 

   
1. When you complete the application for your initial purchase of Fund 
   shares, you authorize exchanges automatically by telephone unless you 
   check the box indicating that you do not wish to authorize telephone 
   exchanges. 
    

2. Call 1-800-225-5291. Have the account number of your current fund and the 
   exact name in which it is registered available to give to the telephone 
   representative. 

3. Your name, the account number, taxpayer identification number applicable 
   to the account and other relevant information may be requested. In 
   addition, telephone instructions are recorded. 

                                      23

In Writing 

1. In a letter request an exchange and list the following: 

   
 --name and class of the Fund whose shares you currently own 
 --your account number 
 --the name(s) in which the account is registered 
 --the name of the fund in which you wish your exchange to be invested 
 --the number of shares, all shares or the dollar amount you wish to exchange 
 Sign your request exactly as the account is registered. 
    

2. Mail the request and information to:

Reinvestment Privilege 

   
[sidebar] 
If you redeem shares of the 
Fund, you may be able to 
reinvest all or part of the 
proceeds in shares of this 
Fund or another John 
Hancock fund without 
paying an additional sales 
charge. 
    

   
1. You will not be subject to a sales charge on Class A shares that you 
   reinvest in a John Hancock fund that is otherwise subject to a sales 
   charge, as long as you reinvest within 120 days of the redemption date. If 
   you paid a CDSC upon a redemption, you may reinvest at net asset value in 
   the same class of shares from which you redeemed within 120 days. Your 
   account will be credited with the amount of the CDSC previously charged, 
   and the reinvested shares will continue to be subject to a CDSC. The 
   holding period of the shares acquired through reinvestment, for purposes 
   of computing the CDSC payable upon a subsequent redemption, will include 
   the holding period of the redeemed shares. 
    

   
2. Any portion of your redemption may be reinvested in Fund shares or in 
   shares of other John Hancock funds, subject to the minimum investment 
   limit of that fund. 
    

   
3. To reinvest, you must notify Investor Services in writing. Include the 
   Fund's name, account number and class from which your shares were 
   originally redeemed. 
    

Systematic Withdrawal Plan 

[sidebar] 
You can pay routine bills 
from your account, or make 
periodic disbursements from 
your retirement account to 
comply with IRS regulations. 

1. You can elect the Systematic Withdrawal Plan at any time by completing the 
   Account Privileges Application which is attached to this Prospectus. You 
   can also obtain the application from your registered representative or by 
   calling 1-800-225-5291. 

2. To be eligible, you must have at least $5,000 in your account. 

   
3. Payments from your account can be made monthly, quarterly, semi-annually 
   or on a selected monthly basis, to yourself or any other designated payee. 
    

4. There is no limit on the number of payees you may authorize, but all 
   payments must be made at the same time or intervals. 

   
5. It is not advantageous to maintain a Systematic Withdrawal Plan 
   concurrently with purchases of additional Class A or Class B shares, 
   because you may be subject to an 
    


                                      24 
<PAGE>
 
   initial sales charge on your purchases of Class A shares or to a CDSC on 
   your redemptions of Class B shares. In addition, your redemptions are 
   taxable events. 

6. Redemptions will be discontinued if the U.S. Postal Service cannot deliver 
   your checks, or if deposits to a bank account are returned for any reason. 

Monthly Automatic Accumulation Program (MAAP) 

[sidebar] 
You can make automatic 
investments and simplify your 
investing. 

   
1. You can authorize an investment to be withdrawn automatically each month 
   on your bank, for investment in Fund shares, under the "Automatic 
   Investing" and "Bank Information" sections of the Account Privileges 
   Application. 
    

2. You can also authorize automatic investing through payroll deduction by 
   completing the "Direct Deposit Investing" section of the Account 
   Privileges Application. 

3. You can terminate your Monthly Automatic Accumulation Program at any time. 

4. There is no charge to you for this program, and there is no cost to the 
   Fund. 

   
5. If you have payments withdrawn from a bank account and we are notified 
   that the account has been closed, your withdrawals will be discontinued. 
    

Group Investment Program 

[sidebar] 
Organized groups of at least 
four persons may establish 
accounts. 

1. An individual account will be established for each participant, but the 
   initial sales charge for Class A shares will be based on the aggregate 
   dollar amount of all participants' investments. To determine how to 
   qualify for this program, contact your registered representative or call 
   1-800-225-5291. 

2. The initial aggregate investment of all participants in the group must be 
   at least $250. 

3. There is no additional charge for this program. There is no obligation to 
   make investments beyond the minimum, and you may terminate the program at 
   any time. 

Retirement Plans 

   
1. You may use the Fund for various types of retirement plans, such as 
   Individual Retirement Accounts, Keogh plans (H.R. 10), pension and profit 
   sharing plans (including 401(k) Plans), Tax-Sheltered Annuity retirement 
   plans (403(b) or TSA plans), and Section 457 plans. 
    

   
2. The initial investment minimum or aggregate minimum for any of these plans 
   is $250. However, accounts being established as group IRA, SEP, SARSEP, 
   TSA, 401(k) and Section 457 plans will be accepted without an initial 
   minimum investment.

APPENDIX 

Moody's describes its lower ratings for corporate bonds as follows. 

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. 

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 are well safeguarded 
during both good and bad times over the future. Uncertainty of position 
characterizes bonds in this class. 

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. 

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. 

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. 

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. 

S&P describes its lower ratings for corporate bonds as follows: 

Debt rated BBB is regarded as having an adequate capacity to pay interest and 
repay principal. Whereas it normally exhibits adequate protection parameters, 
adverse economic conditions or changing circumstances are more likely to lead 
to a weakened capacity to pay interest and repay principal for debt in this 
category than in higher rated categories. 

Debt rated BB, B, CCC, or C is regarded, on balance, as predominantly 
speculative with respect to the issuer's capacity to pay interest and repay 
principal in accordance with the terms of the obligations. BB indicates the 
lowest degree of speculation and CC the highest degree of speculation. While 
such debt will likely have some quality and protective characteristics, these 
are outweighed by large uncertainties or major risk exposures to adverse 
conditions.

ORGANIZATION OF THE FUND
   
     John Hancock  Sovereign  Bond Fund (the "Fund") is a  diversified  open-end
management investment company organized as a Massachusetts  business trust under
the laws of The Commonwealth of Massachusetts. The Fund was organized in 1984 by
John Hancock  Advisers,  Inc.  (the  "Adviser") as the successor to John Hancock
Bond Fund, Inc., a Maryland  corporation  organized in 1973 by the Adviser.  The
Adviser is an  indirect  wholly-owned  subsidiary  of John  Hancock  Mutual Life
Insurance Company (the "Life Company"),  a Massachusetts  life insurance company
chartered in 1862,  with national  headquarters  at John Hancock Place,  Boston,
Massachusetts.
    
INVESTMENT OBJECTIVE AND POLICIES
   
     The  Fund's  investment  objective  is to  generate a high level of current
income,  consistent  with  prudent  investment  risk,  for  distribution  to its
shareholders through investment in a diversified  portfolio of freely marketable
debt  securities.   The  Fund's  investments  will  be  subject  to  the  market
fluctuations  and risks inherent in all  securities.  There is no assurance that
the Fund will achieve its investment  objective.  See "Investment  Objective and
Policies" in the Fund's Prospectus.
    
     The Fund will invest  primarily in debt securities  within the four highest
investment  ratings and unrated  securities  considered  by the Adviser to be of
comparable  investment  quality.  The Fund will,  when  feasible,  purchase debt
securities which are non-callable.

     The Fund may purchase  corporate debt securities bearing fixed or fixed and
contingent  interest as well as those which carry certain equity features,  such
as conversion or exchange rights or warrants for the acquisition of stock of the
same or a  different  issuer,  or  participations  based on  revenues,  sales or
profits.  The Fund will not exercise any such  conversion,  exchange or purchase
rights if, at the time, the value of all equity  interests so owned would exceed
10% of the Fund's total assets taken at market value.

     The market  value of debt  securities  which carry no equity  participation
usually reflects yields generally available on securities of similar quality and
type. When such yields decline, the market value of a portfolio already invested
at higher  yields  can be  expected  to rise if such  securities  are  protected
against early call. Similarly,  when such yields increase, the market value of a
portfolio already invested can be expected to decline.  The Fund's portfolio may
include debt  securities  which sell at  substantial  discounts  from par. These
securities are low coupon bonds which,  during  periods of high interest  rates,
because  of  their  lower  acquisition  cost  tend  to  sell  on a  yield  basis
approximating current interest rates.

     The Fund  intends to use  short-term  trading of  securities  as a means of
managing  its  portfolio  to achieve  its  investment  objective.  The Fund,  in
reaching a decision  to sell one  security  and  purchase  another  security  at
approximately  the same  time,  will  take into  account  a number  of  factors,
including the quality  ratings,  interest rates,  yields,  maturity dates,  call
prices,  and  refunding  and sinking fund  provisions  of the  securities  under
consideration,  as  well  as  historical  


                                       2

<PAGE>

yield  spreads  and current  economic  information.  The  success of  short-term
trading  will  depend  upon  the  ability  of the  Fund to  evaluate  particular
securities, to anticipate relevant market factors,  including trends of interest
rates  and  earnings  and  variations  from  such  trends,  to  obtain  relevant
information,  to evaluate it promptly,  and to take advantage of its evaluations
by  completing  transactions  on a  favorable  basis.  It is  expected  that the
expenses  involved  in  short-term  trading,  which  would not be incurred by an
investment  company  which  does  not  use  this  portfolio  technique,  will be
significantly  less than the  profits  and other  benefits  which will accrue to
shareholders.

     The portfolio  turnover rate will depend on a number of factors,  including
the fact that the Fund intends to continue to qualify as a regulated  investment
company under the Internal Revenue Code. Accordingly,  the Fund intends to limit
its  short-term  trading so that less than 30% of the Fund's gross annual income
(including all dividend and interest  income and gross  realized  capital gains,
both short and long-term, without being offset for realized capital losses) will
be  derived  from  gross  realized  gains on the sale or  other  disposition  of
securities held for less than three months.  This limitation,  which must be met
by all mutual  funds in order to obtain such Federal tax  treatment,  at certain
times may prevent the Fund from realizing  capital gains on some securities held
for less than three months.

CERTAIN INVESTMENT PRACTICES

     When-Issued Securities.  "When-issued" refers to securities whose terms are
available and for which a market exists,  but which have not yet been issued. No
payment is made with respect to a  when-issued  transaction,  until  delivery is
due, often a month or more after the purchase.

     The Fund may engage in when-issued  transactions with respect to securities
purchased for its portfolio in order to obtain an  advantageous  price and yield
at the  time  of the  transactions.  When  the  Fund  engages  in a  when-issued
transaction, it relies on the seller to consummate the transaction.  The failure
of the issuer or seller to  consummate  the  transaction  may result in the Fund
losing  the   opportunity  to  obtain  a  price  and  yield   considered  to  be
advantageous.  On the  date  the  Fund  enters  into an  agreement  to  purchase
securities on a when-issued basis, the Fund will segregate in a separate account
cash or liquid, high grade debt securities (i.e., securities rated in one of the
top three ratings  categories by Moody's Investors  Service,  Inc.("Moody's") or
Standard  & Poor's  Ratings  Group  ("S&P)  equal  in  value to the  when-issued
commitment.  These assets will be valued daily at market, and additional cash or
liquid,  high grade debt securities will be segregated in a separate  account to
the extent that the total value of the assets in the account  declines below the
amount of the when-issued commitment.

     Repurchase Agreements. A repurchase agreement is a contract under which the
Fund would  acquire a security for a relatively  short period  (usually not more
than 7 days) subject to the  obligation of the seller to repurchase and the Fund
to resell such security at a fixed time and price  (representing the Fund's cost
plus interest).  The Fund will enter into repurchase agreements only with member
banks  of the  Federal  Reserve  System  and  with  "primary  dealers"  in  U.S.
Government    securities.    The   Adviser   will   continuously   monitor   the
creditworthiness  of the  parties  with  whom the Fund  enters  into  repurchase
agreements.  The Fund has established a procedure  providing that the securities
serving as collateral  for each  repurchase  agreement  must be delivered 


                                       3

<PAGE>

to the Fund's  custodian  either  physically or in book-entry  form and that the
collateral  must be  marked  to market  daily to  ensure  that  each  repurchase
agreement is fully  collateralized  at all times.  In the event of bankruptcy or
other default by a seller of a repurchase  agreement,  the Fund could experience
delays in liquidating  the underlying  securities and could  experience  losses,
including the possible decline in the value of the underlying  securities during
the  period  which  the Fund  seeks to  enforce  its  rights  thereto,  possible
subnormal levels of income and lack of access to income during this period,  and
the expense of enforcing its rights.

     Restricted  Securities.  The  Fund may  invest  in  restricted  securities,
including those eligible for resale to certain institutional  investors pursuant
to Rule 144A under the Securities Act of 1933 and foreign securities acquired in
accordance with Regulation S under the Securities Act of 1933. The Fund will not
invest more than 15% of its net assets in illiquid  investments,  which includes
repurchase agreements maturing in more than seven days, OTC options,  securities
that are not readily marketable and restricted securities. However, if the Board
of Trustees determines based upon a continuing review of the trading markets for
specific Rule 144A securities,  that they are liquid then such securities may be
purchased  without  regard to the 15%  limit.  The Board of  Trustees  may adopt
guidelines  and delegate to the Adviser the daily  function of  determining  and
monitoring  the liquidity of restricted  securities.  The Board,  however,  will
retain   sufficient   oversight   and  be   ultimately   responsible   for   the
determinations. The Board will carefully monitor the Fund's investments in these
securities,  focusing on such  important  factors,  among others,  as valuation,
liquidity and availability of information.  This investment  practice could have
the  effect of  increasing  the level of  illiquidity  in the Fund if  qualified
institutional  buyers  become  for  a  time  uninterested  in  purchasing  these
restricted securities.

     Financial Futures Contracts. The Fund may hedge its portfolio by selling or
purchasing  financial  futures  contracts  as an offset  against  the effects of
changes in interest rates or in security or foreign  currency  values.  Although
other  techniques  could be used to reduce the Fund's  exposure to interest rate
fluctuations,  the Fund may be able to hedge its exposure more  effectively  and
perhaps at a lower cost by using financial futures contracts. The Fund may enter
into financial  futures  contracts for hedging and  speculative  purposes to the
extent  permitted by regulations  of the Commodity  Futures  Trading  Commission
("CFTC").

     Financial  futures  contracts  have been  designed by boards of trade which
have been  designated  "contract  markets" by the CFTC.  Futures  contracts  are
traded on these markets in a manner that is similar to the way a stock is traded
on a stock exchange.  The boards of trade, through their clearing  corporations,
guarantee that the contracts  will be performed.  Currently,  financial  futures
contracts are based on interest rate instruments such as long-term U.S. Treasury
bonds, U.S. Treasury notes,  Government National Mortgage  Association  ("GNMA")
modified  pass-through  mortgage-backed  securities,  three-month U.S.  Treasury
bills,  90-day  commercial  paper,  bank  certificates of deposit and Eurodollar
certificates  of  deposit.  It is  expected  that  if  other  financial  futures
contracts are developed and traded the Fund may engage in  transactions  in such
contracts.

     Although some  financial  futures  contracts by their terms call for actual
delivery or acceptance of financial instruments, in most cases the contracts are
closed  out prior to  delivery  by  offsetting  purchases  or sales of  matching
financial  futures  contracts (same exchange,  underlying  


                                       4

<PAGE>

security and delivery month). Other financial futures contracts, such as futures
contracts on securities  indices,  by their terms call for cash settlements.  If
the offsetting  purchase price is less than the Fund's original sale price,  the
Fund realizes a gain, or if it is more, the Fund realizes a loss. Conversely, if
the offsetting sale price is more than the Fund's original  purchase price,  the
Fund  realizes  a  gain,  or if it is  less,  the  Fund  realizes  a  loss.  The
transaction costs must also be included in these calculations. The Fund will pay
a commission  in  connection  with each  purchase or sale of  financial  futures
contracts,  including a closing  transaction.  For a  discussion  of the Federal
income tax  considerations  of trading in financial futures  contracts,  see the
information under the caption "Tax Status" below.

     At the  time the Fund  enters  into a  financial  futures  contract,  it is
required  to  deposit  with its  custodian  a  specified  amount of cash or U.S.
Government  securities,  known as "initial  margin," ranging upward from 1.1% of
the value of the financial  futures  contract being traded.  The margin required
for a  financial  futures  contract  is set by the board of trade or exchange on
which  the  contract  is  traded  and may be  modified  during  the  term of the
contract.  The  initial  margin is in the nature of a  performance  bond or good
faith deposit on the financial  futures  contract  which is returned to the Fund
upon termination of the contract, assuming all contractual obligations have been
satisfied.  The Fund  expects  to earn  interest  income on its  initial  margin
deposits.  Each day, the futures  contract is valued at the official  settlement
price  of the  board  of trade or  exchange  on which it is  traded.  Subsequent
payments,  known as  "variation  margin,"  to and from the  broker are made on a
daily basis as the market price of the financial  futures  contract  fluctuates.
This process is known as "mark to market." Variation margin does not represent a
borrowing or lending by the Fund but is instead  settlement between the Fund and
the  broker of the  amount  one would  owe the  other if the  financial  futures
contract expired. In computing net asset value, the Fund will mark to market its
open financial futures positions.
   
     Successful hedging depends on a strong  correlation  between the market for
the underlying  securities and the futures contract market for those securities.
There are several factors that may prevent this  correlation  from being perfect
and even a correct  forecast of general interest rate trends may not result in a
successful hedging  transaction.  There are significant  differences between the
securities  and futures  markets  which could  create an  imperfect  correlation
between the markets and which  could  affect the success of a given  hedge.  The
degree of  imperfection  will be affected by  variations in  speculative  market
demand for financial futures and debt securities, including technical influences
in futures trading.  Differences between the financial  instruments being hedged
and  the  instruments   underlying  the  standard  financial  futures  contracts
available for trading will be affected by interest rate levels,  maturities  and
creditworthiness  of issuers.  The degree of imperfection may be increased where
the  underlying  debt  securities are  lower-rated  and,  therefore,  subject to
greater fluctuation in price than higher-rated securities.
    
     A decision as to whether,  when and how to hedge  involves  the exercise of
skill and judgment,  and even a well-conceived hedge may be unsuccessful to some
degree because of market behavior or unexpected  interest rate trends.  The Fund
will bear the risk that the price of the  securities  being hedged will not move
in  complete  correlation  with the  price of the  futures  contracts  used as a
hedging  instrument.  Although  the Adviser  believes  that the use of financial
futures contracts will benefit the Fund, an incorrect prediction could result in
a loss on both the hedged  securities  in the Fund's  portfolio  and the hedging
vehicle so that the Fund's  return  might


                                       5

<PAGE>

have been better had hedging not been attempted.  However, in the absence of the
ability to hedge, the Adviser might have taken portfolio actions in anticipation
of the same market movements with similar investment results but, presumably, at
greater  transaction  costs.  The  low  margin  deposits  required  for  futures
transactions  permit an extremely  high degree of leverage.  A relatively  small
movement  in a futures  contract  may result in losses or gains in excess of the
amount invested.

     Futures exchanges may limit the amount of fluctuation  permitted in certain
futures contract prices during a single trading day. The daily limit establishes
the maximum  amount the price of a futures  contract  may vary either up or down
from the previous  day's  settlement  price,  at the end of the current  trading
session.  Once the daily limit has been reached in a futures contract subject to
the limit,  no more trades may be made on that day at a price beyond that limit.
The daily limit  governs only price  movements  during a particular  trading day
and,  therefore,  does not limit potential  losses because the limit may work to
prevent the liquidation of unfavorable  positions.  For example,  futures prices
have occasionally moved to the daily limit for several  consecutive trading days
with little or no trading,  thereby  preventing prompt  liquidation of positions
and subjecting some holders of futures contracts to substantial losses.

     Finally,  although the Fund engages in financial futures  transactions only
on boards of trade or exchanges where there appears to be an adequate  secondary
market,  there is no assurance  that a liquid market will exist for a particular
futures  contract  at any given time.  The  liquidity  of the market  depends on
participants closing out contracts rather than making or taking delivery. In the
event  participants  decide to make or take  delivery,  liquidity  in the market
could be reduced. In addition,  the Fund could be prevented from executing a buy
or sell order at a specified  price or closing  out a position  due to limits on
open  positions or daily price  fluctuation  limits  imposed by the exchanges or
boards of trade. If the Fund cannot close out a position, it will be required to
continue to meet margin requirements until the position is closed.

     Options on  Financial  Futures  Contracts.  The Fund may purchase and write
call and put  options on  financial  futures  contracts.  An option on a futures
contract  gives the  purchaser  the right,  in return for the premium  paid,  to
assume a position in a futures  contract at a  specified  exercise  price at any
time during the period of the option.  Upon  exercise,  the writer of the option
delivers  the futures  contract to the holder at the  exercise  price.  The Fund
would be required to deposit with its  custodian  initial and  variation  margin
with respect to put and call options on futures contracts written by it. Options
on futures contracts involve risks similar to the risks relating to transactions
in financial futures contracts. Also, an option purchased by the Fund may expire
worthless, in which case the Fund would lose the premium it paid for the option.

     Other Considerations. The Fund will engage in futures transactions for bona
fide  hedging  or  speculative   purposes  to  the  extent   permitted  by  CFTC
regulations.  The Fund will determine that the price fluctuations in the futures
contracts  and options on futures used for hedging  purposes  are  substantially
related to price fluctuations in securities held by the Fund or which it expects
to purchase.  Except as stated below,  the Fund's futures  transactions  will be
entered into for traditional hedging purposes -- i.e., futures contracts will be
sold to protect  against  decline in the price of securities that the Fund owns,
or futures  contracts  will be purchased to protect the Fund against an increase
in the price of  securities  or the  currency in which they are  denominated  it
intends to purchase.  As evidence of this hedging intent,  the Fund expects that
on 75% or more of 


                                       6

<PAGE>

the occasions on which it takes a long futures or option position (involving the
purchase of futures contracts),  the Fund will have purchased, or will be in the
process  of  purchasing  equivalent  amounts  of  related  securities  or assets
denominated  in the  related  currency  in the cash  market at the time when the
futures or option position is closed out. However,  in particular cases, when it
is economically  advantageous for the Fund to do so, a long futures position may
be  terminated  or an option may expire  without the  corresponding  purchase of
securities or other assets.

     As an  alternative  to  literal  compliance  with  the  bona  fide  hedging
definition,  a CFTC  regulation  permits  the  Fund to elect  to  comply  with a
different test, under which the aggregate  initial margin and premiums  required
to establish  speculative  positions in futures contracts and options on futures
will not exceed 5% of the net asset value of the Fund's portfolio,  after taking
into account  unrealized  profits and losses on any such positions and excluding
the amount by which such options were in-the-money at the time of purchase.  The
Fund will engage in  transactions  in futures  contracts only to the extent such
transactions  are consistent with the  requirements of the Internal Revenue Code
for maintaining its qualification as a regulated  investment company for Federal
income tax purposes.

     When the Fund  purchases  a  financial  futures  contract,  or writes a put
option or  purchases  a call  option  thereon,  cash and high grade  liquid debt
securities will be deposited in a segregated  account with the Fund's  custodian
in an amount that, together with the amount of initial and variation margin held
in the account of its broker, equals the market value of the futures contract.

     Lower  Rated  High  Yield  Debt  Obligations.  The Fund may  invest in high
yielding,  fixed income securities rated Baa or lower by Moody's or BBB or lower
by S&P. The Fund will not invest in  securities  rated below Ca by Moody's or CC
by S&P. Ratings are based largely on the historical  financial  condition of the
issuer.  Consequently,  the rating  assigned to any  particular  security is not
necessarily a reflection of the issuer's current financial condition,  which may
be better or worse than the rating would indicate.

     The values of lower-rated securities generally fluctuate more than those of
high-rated  securities.  In  addition,  the  lower  rating  reflects  a  greater
possibility of an adverse change in financial condition affecting the ability of
the issuer to make  payments of interest  and  principal.  The Adviser  seeks to
minimize these risks through diversification,  investment analysis and attention
to current developments in interest rates and economic conditions. To the extent
the Fund invests in securities in the lower rating  categories,  the achievement
of the Fund's goals is more dependent on the Adviser's ability than would be the
case if the Fund were investing in securities in the higher rated categories.

INVESTMENT RESTRICTIONS
   
Fundamental Investment  Restrictions.  The following investment restrictions (as
well as the Fund's investment objective) will not be changed without approval of
a majority of the Fund's  outstanding  voting  securities  which, as used in the
Prospectus and this Statement of Additional  Information,  means approval by the
lesser of (1) 67% or more of the Fund's  shares  represented  at a meeting if at
least 50% of the Fund's  outstanding shares are present in person or by proxy at
the meeting or (2) 50% of the Fund's outstanding shares.
    
     The Fund observes the following fundamental restrictions:

     The Fund may not:

     (1) Issue senior securities, except as permitted by paragraphs (2), (6) and
(7)  below.  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 future contracts, forward commitments,
forward foreign  exchange  contracts and repurchase  agreements  entered into in
accordance  with the Fund's  investment  policy,  and the  pledge,  mortgage  or
hypothecation of the Fund's assets within the meaning of paragraph (3) below are
not deemed to be senior securities.

     (2)  Borrow   money,   except  from  banks  as  a  temporary   measure  for
extraordinary  emergency purposes in amounts not to exceed 33 1/3% 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 exceed 5% of the Fund's total assets.

     (3)  Pledge,   mortgage,  or  hypothecate  its  assets,  except  to  secure
indebtedness  permitted by paragraph  (2) above and then only if such  pledging,
mortgaging or  hypothecating  does not exceed 33 1/3% of the Fund's total assets
taken at market value.

     (4) Act as an  underwriter,  except to the extent that, in connection  with
the  disposition  of  portfolio  securities,  the  Fund may be  deemed  to be an
underwriter for purposes of the Securities Act of 1933.

     (5) Purchase or sell real estate or any interest  therein,  except that the
Fund may invest in securities of corporate or governmental  entities  secured by
real estate or marketable interest therein or issued by companies that invest in
real estate or interests therein.

     (6) Make loans,  except that the Fund (1) may lend portfolio  securities in
accordance with the Fund's investment policies up to 33 1/3% of the Fund's total
assets taken at market  value,  (2) enter into  repurchase  agreements,  and (3)
purchase all or a portion of an issue of publicly  distributed  debt securities,
bank loan  participation  interests,  bank  certificates  of  deposit,  bankers'
acceptances, debentures or other securities, whether or not the purchase is made
upon the original issuance of the securities.

     (7) Invest in  commodities  or commodity  contracts or in puts,  calls,  or
combinations  of both,  except  interest  rate  futures  contracts,  options  on
securities,  securities  indices,  currency and other financial  instruments and
options on such futures contracts,  forward foreign currency exchange contracts,
forward  commitments,  securities  index  put or call  warrants  and  repurchase
agreements entered into in accordance with the Fund's investment policies.

     (8) Purchase the securities of issuers  conducting their principal business
activity in the same industry if, immediately after such purchase,  the value of
its  investments  in such industry would exceed 25% of its total assets taken at
market value at the time of each  investment.  This limitation does not apply to
investments  in  obligations  of the U.S.  Government  or any of its agencies or
instrumentalities.

     (9) Purchase securities of an issuer, (other than the U.S. Government,  its
agencies or instrumentalities) if

          (a) Such purchase  would cause more than 5% of the Fund's total assets
          taken at market value to be invested in the securities of such issuer,
          or

          (b) Such  purchase  would at the time  result  in more than 10% of the
          outstanding voting securities of such issuer being held by the Fund.

     In  connection  with the  lending of  portfolio  securities  under item (6)
above,  such  loans  must  at all  times  be  fully  collateralized  by  cash or
securities of the U.S. Government or its agencies or  instrumentalities  and the
Fund's custodian must take possession of the collateral  either physically or in
book entry form.  Any cash  collateral  will consist of short-term  high quality
debt instruments. Securities used as collateral must be marked to market daily.

Nonfundamental Investment Restrictions

     The following  restrictions  are  designated as  nonfundamental  and may be
changed by the Board of Trustees without shareholder approval:

     The Fund may not:

     (a)  Participate  on a joint or  joint-and-several  basis in any securities
trading account. The "bunching" of orders for the sale or purchase of marketable
portfolio  securities with other accounts under the management of the Adviser to
save  commissions  or to average  prices among them is not deemed to result in a
securities trading account.

     (b)  Purchase  securities  on margin or make  short  sales,  except  margin
deposits in connection with transactions in options, futures contracts,  options
on futures contracts and other arbitrage transactions or unless by virtue of its
ownership  of other  securities,  the Fund has the  right to  obtain  securities
equivalent  in kind and  amount  to the  securities  sold  and,  if the right is
conditional, the sale is made upon the same conditions, except that the Fund may
obtain  such  short-term  credits  as may be  necessary  for  the  clearance  of
purchases and sales of securities and in connection with transactions  involving
forward foreign currency exchange transactions.


                                       9

<PAGE>

     (c)  Purchase a security  if, as a result,  (i) more than 10% of the Fund's
total assets would be invested in securities of closed-end investment companies,
(ii) such purchase would result in more than 3% of the total outstanding  voting
securities of any one such closed-end investment company being held by the Fund,
or (iii) more than 5% of the Fund's  total  assets  would be invested in any one
such closed-end  investment company.  The Fund will not invest in the securities
of any open-end investment company.

     (d) Purchase securities of any issuer which, together with any predecessor,
has a record  of less  than  three  years'  continuous  operations  prior to the
purchase  if such  purchase  would  cause  investments  of the  Fund in all such
issuers to exceed 5% of the value of the total assets of the Fund.

     (e) Invest for the purpose of exercising  control over or management of any
company.

     (f)  Purchase  warrants of any issuer,  if, as a result of such  purchases,
more  than 2% of the value of the  Fund's  total  assets  would be  invested  in
warrants  which are not listed on the New York Stock  Exchange  or the  American
Stock  Exchange  or more than 5% of the  value of the  total  assets of the Fund
would be  invested in warrants  generally,  whether or not so listed.  For these
purposes,  warrants are to be valued at the lesser of cost or market value,  but
warrants acquired by the Fund in units with or attached to debt securities shall
be deemed to be without value.

     (g) Knowingly  purchase or retain securities of an issuer if one or more of
the  Trustees or officers of the Fund or directors or officers of the Adviser or
any  investment   management   subsidiary  of  the  Adviser   individually  owns
beneficially  more than 0.5%, and together own beneficially more than 5%, of the
securities of such issuer.

     (h) Purchase  interests in oil, gas or other mineral  leases or exploration
programs;  however,  this policy will not prohibit the acquisition of securities
of companies  engaged in the  production  or  transmission  of oil, gas or other
minerals.

     (i) Invest more than (i) 10% of its total  assets in  securities  which are
restricted  under  the  Securities  Act of  1933  (the  "1933  Act")  (excluding
restricted  securities  that are eligible for resale pursuant to Rule 144A under
the  1933  Act)  or (ii)  15% of the  Fund's  total  assets  in such  restricted
securities (including restricted securities eligible for resale pursuant to Rule
144A).

     (j) Purchase interests in real estate limited partnerships.

     (k) Purchase any security,  including any repurchase  agreement maturing in
more than seven days, which is not readily  marketable,  if more than 15% of the
net  assets  of the Fund,  taken at  market  value,  would be  invested  in such
securities.  (The staff of the  Securities  and  Exchange  Commission  considers
over-the-counter options to be illiquid securities subject to the 15% limit.)

     (l)  Notwithstanding any investment  restriction to the contrary,  the Fund
may, in connection  with the John Hancock Group of Funds  Deferred  Compensation
Plan for Independent Trustees/Directors, purchase securities of other investment
companies within the John Hancock 


                                       10

<PAGE>

Group of Funds  provided  that, as a result,  (i) no more than 10% of the Fund's
assets would be invested in securities of all other investment  companies,  (ii)
such purchase would not result in more than 3% of the total  outstanding  voting
securities of any one such  investment  company being held by the Fund and (iii)
no more  that  5% of the  Fund's  assets  would  be  invested  in any  one  such
investment company.

     In order to permit  the sale of shares of the Fund in certain  states,  the
Trustees may, in their sole discretion,  adopt restrictions on investment policy
more restrictive than those described above.  Should the Trustees determine that
any such more  restrictive  policy is no longer in the best interest of the Fund
and its  shareholders,  the Fund may cease offering shares in the state involved
and the Trustees may revoke such  restrictive  policy.  Moreover,  if the states
involved shall no longer require any such restrictive  policy, the Trustees may,
at their sole discretion, revoke such policy.

     If a percentage  restriction  on investment or utilization of assets as set
forth above is adhered to at the time an  investment  is made, a later change in
percentage  resulting from changes in the value of the Fund's assets will not be
considered a violation of restriction.

THOSE RESPONSIBLE FOR MANAGEMENT

     The business of the Fund is managed by its Trustees, who elect officers who
are  responsible  for the  day-to-day  operations  of the Fund  and who  execute
policies formulated by the Trustees. Several of the officers and Trustees of the
Fund are also officers and directors of the Adviser or officers and directors of
the Fund's  principal  distributor,  John Hancock  Funds,  Inc.  ("John  Hancock
Funds").

     The following  table sets forth the  principal  occupation or employment of
the Trustees and principal officers of the Fund during the past five years:

INVESTMENT ADVISORY AND OTHER SERVICES
   
     As described in the  Prospectus,  the Fund receives its  investment  advice
from the Adviser.  Investors should refer to the Prospectus for a description of
certain information concerning the investment management contract.
    
     Each of the  Trustees  and  principal  officers  of the Fund who is also an
affiliated  person of the Adviser is named above,  together with the capacity in
which such person is affiliated with the Fund and the Adviser.
   
     As  described  in  the  Prospectus  under  the  caption  "Organization  and
Management  of the Fund," the Fund has  entered  into an  investment  management
contract with the Adviser. Under the investment management contract, the Adviser
provides the Fund (i) with a continuous investment program,  consistent with the
Fund's stated investment objective and policies, (ii) supervision of all aspects
of the Fund's operations  except those delegated to a custodian,  transfer agent
or other agent and (iii) such executive,  administrative and clerical personnel,
officers and equipment as are  necessary  for the conduct of its  business.  The
Adviser is responsible for the management of the Fund's portfolio assets.
    
     Securities  held by the Fund may also be held by other funds or  investment
advisory  clients for which the Adviser or its  affiliates  provides  investment
advice.   Because  of  different  investment  objectives  or  other  factors,  a
particular  security  may be bought for one or more funds or clients when one or
more other funds or clients are selling the same security.  If opportunities for
the purchase or sale of securities by the Adviser or for other funds or clients,
for which the Adviser renders investment  advice,  arise for consideration at or
about the same time,  transactions in such  securities will be made,  insofar as
feasible,  for the respective  funds or clients in a manner deemed  equitable to
all of them. To the extent that  transactions  on behalf of more than one client
of the 


                                       17

<PAGE>

Adviser or its affiliates may increase the demand for securities being purchased
or the supply of securities being sold, there may be an adverse effect on price.
   
     No person other than the Adviser and its directors and employees  regularly
furnishes  advice to the Fund with  respect  to the  desirability  of the Fund's
investing  in,  purchasing or selling  securities.  The Adviser may from time to
time receive statistical or other similar factual  information,  and information
regarding  general  economic  factors and trends,  from the Life Company and its
affiliates.
    
     Under the terms of the  investment  management  contract with the Fund, the
Adviser  provides  the Fund with office  space,  supplies  and other  facilities
required for the business of the Fund. The Adviser pays the  compensation of all
other  officers  and  employees  of the Fund,  and pays the expenses of clerical
services relating to the administration of the Fund.
   
     All expenses which are not  specifically  paid by the Adviser and which are
incurred in the  operation of the Fund  (including  fees of Trustees of the Fund
who are not  "interested  persons,"  as such term is defined  in the  Investment
Company Act, but excluding certain  distribution  related activities required to
be paid by the Adviser or John Hancock Funds) and the continuous public offering
of the shares of the Fund are borne by the Fund.
    
   
     As  provided  by the  investment  management  contract,  the Fund  pays the
Adviser  monthly  an  investment  management  fee,  which  is  based on a stated
percentage of the Fund's average of the daily net assets as follows:
    

            Net Asset Value                         Annual Rate
            ---------------                         -----------
          First $1,500,000,000                         0.50%
           Next $500,000,000                           0.45%
           Next $500,000,000                           0.40%
       Amount over $2,500,000,000                      0.35%

     From  time  to  time,  the  Adviser  may  reduce  its  fee  or  make  other
arrangements to limit the Fund's  expenses to a specified  percentage of average
daily net assets.  The Adviser  retains the right to re-impose a fee and recover
any other payments to the extent that, at the end of any fiscal year, the Fund's
annual expenses fall below this limit.
   
     On December 31, 1995, the net assets of the Fund were  $1,633,942,540.  For
the years ended December 31, 1993,  1994, and 1995 the Adviser  received fees of
$6,488,835  and  $7,116,092  and  $7,406,635,  respectively.  The  1992 and 1993
advisory fee figures  reflect the  different  advisory fee schedule  that was in
effect before January 1, 1994.
    
   
     If the total of all ordinary  business  expenses of the Fund for any fiscal
year exceeds limitations prescribed by any state in which shares of the Fund are
qualified for sale, the fee payable to the Adviser will be reduced to the extent
required  by these  limitations.  At this time,  the most  restrictive  limit on
expenses  imposed by a state  requires that expenses  charged to the Fund in any
fiscal year not exceed 2 1/2% of the first $30,000,000 of the Fund's average net



                                       18

<PAGE>

assets,  2% of the  next  $70,000,000  of  such  net  assets,  and 1 1/2% of the
remaining  average net assets.  When  calculating the above limit,  the Fund may
exclude interest, brokerage commissions and extraordinary expenses.
    
     Pursuant to its investment  management contract,  the Adviser is not liable
to the Fund or its  shareholders  for any error of judgment or mistake of law or
for any loss  suffered by the Fund in  connection  with the matters to which the
investment  management  contract  relates,  except a loss resulting from willful
misfeasance,  bad faith or gross  negligence  on the part of the  Adviser in the
performance  of its  duties or from  reckless  disregard  by the  Adviser of its
obligations and duties under the investment management contract.
   
     The  Adviser,  located  at 101  Huntington  Avenue,  Boston,  Massachusetts
02199-7603,  was  organized in 1968 and  presently  has more than $16 billion in
assets under  management in its capacity as  investment  adviser to the Fund and
the other  mutual  funds and publicly  traded  investment  companies in the John
Hancock group of funds having a combined total of over  1,080,000  shareholders.
The Adviser is an affiliate of the Life Company,  one of the most recognized and
respected  financial  institutions  in  the  nation.  With  total  assets  under
management  of $80  billion,  the Life  Company is one of the ten  largest  life
insurance  companies in the United  States,  and carries high ratings from S&P's
and A. M. Best.  Founded in 1862, the Life Company has been serving  clients for
over 130 years.
    
   
     Under the investment  management contract,  the Fund may use the name "John
Hancock"  or any  name  derived  from or  similar  to it only for so long as the
contract or any extension,  renewal or amendment  thereof remains in effect.  If
the  contract  is no longer in effect,  the Fund (to the extent that it lawfully
can)  will  cease to use such a name or any  other  name  indicating  that it is
advised by or otherwise connected with the Adviser. In addition,  the Adviser or
the Life Company may grant the nonexclusive right to use the name "John Hancock"
or any  similar  name to any other  corporation  or  entity,  including  but not
limited to any investment company of which the Life Company or any subsidiary or
affiliate  thereof  or any  successor  to the  business  of  any  subsidiary  or
affiliate thereof shall be the investment adviser.
    
   
     The investment management contract continues in effect from year to year if
approved  annually by vote of a majority of the Trustees who are not  interested
persons  of one of the  parties  to the  contract,  cast in  person at a meeting
called for the purpose of voting on such approval, and by either the Trustees or
the  holders of a majority  of the Fund's  outstanding  voting  securities.  The
contract automatically  terminates upon assignment and may be terminated without
penalty on 60 days'  notice at the option of either  party to the contract or by
vote of a majority of the outstanding voting securities of the Fund.
    
DISTRIBUTION CONTRACT
   
     The Fund has a  distribution  contract with John Hancock  Funds.  Under the
contract, John Hancock Funds is obligated to use its best efforts to sell shares
of the Fund.  Shares of the Fund are also sold by selected  broker-dealers  (the
"Selling  Brokers") which have entered into selling agency  agreements with John
Hancock Funds.  John Hancock Funds accepts orders for the purchase of the shares
of the Fund which are  continually  offered at net asset  value next  


                                       19

determined  plus any  applicable  sales charge.  In connection  with the sale of
Class A and Class B shares,  John  Hancock  Funds and  Selling  Brokers  receive
compensation  in the  form of a sales  charge  imposed,  in the  case of Class A
shares,  at the time of sale or,  in the case of Class B shares,  on a  deferred
basis. The sales charges are discussed further in the Prospectus.
    
   
     The Fund's Trustees adopted  Distribution Plans with respect to the Class A
and Class B shares (the  "Plans")  pursuant  to Rule 12b-1 under the  Investment
Company Act of 1940. Under the Plans, the Fund will pay distribution and service
fees at an aggregate annual rate of up to 0.30% and 1.00%, respectively,  of the
Fund's  daily net assets  attributable  to shares of that  class.  However,  the
service fee will not exceed 0.25% of the Fund's daily net assets attributable to
each class of shares. The distribution fees reimburse John Hancock Funds for its
distribution  costs  incurred in the promotion of sales of Fund shares,  and the
service  fees  compensate  Selling  Brokers for  providing  personal and account
maintenance  services to  shareholders.  In the event that John Hancock Funds is
not fully  reimbursed for expenses  incurred by it under the Class B Plan in any
fiscal year,  John Hancock  Funds may carry these  expenses  forward,  provided,
however that the Trustees may terminate the Class B Plan and,  thus,  the Fund's
obligation to make further payments at any time. Accordinlgy,  the Fund does not
treat unreimbursed expenses relating to the Class B shares as a liability of the
Fund.  The Plans were  approved  by a majority of the voting  securities  of the
Fund.  The Plans and all amendments  were approved by the Trustees,  including a
majority of the Trustees who are not interested persons of the Fund and who have
no direct or  indirect  financial  interest in the  operation  of the Plans (the
"Independent  Trustees"),  by votes  cast in person at  meetings  called for the
purpose of voting on these Plans.
    
   
     Pursuant to the Plans, at least quarterly,  John Hancock Funds provides the
Fund  with a  written  report of the  amounts  expended  under the Plans and the
purpose  for which these  expenditures  were made.  The  Trustees  review  these
reports on a quarterly basis.
    
   
     During the fiscal year ended  December  31, 1995 the Fund paid John Hancock
Funds the  following  amounts of expenses with respect to the Class A shares and
Class B shares of the Fund:

     Each of the Plans  provides that it will continue in effect only so long as
its continuance is approved at least annually by a majority of both the Trustees
and  the  Independent  Trustees.  Each  of the  Plans  provides  that  it may be
terminated  without  penalty  (a) by  vote  of a  majority  of  the  Independent
Trustees,  (b) by a majority of the Fund's  outstanding shares of the applicable
class in each case upon 60 days' written notice to John Hancock  Funds,  and (c)
automatically  in the event

of assignment.  Each of the Plans further provides that it may not be amended to
increase  the  maximum  amount of the fees for the  services  described  therein
without the approval of a majority of the outstanding shares of the class of the
Fund which has voting rights with respect to the Plan. And finally,  each of the
Plans  provides that no material  amendment to the Plan will,  in any event,  be
effective  unless it is approved by a vote of the Trustees  and the  Independent
Trustees  of the Fund.  The  holders of Class A shares  and Class B shares  have
exclusive  voting rights with respect to the Plan applicable to their respective
class of shares.  In adopting the Plans the Trustees  concluded  that,  in their
judgment,  there is a  reasonable  likelihood  that each Plan will  benefit  the
holders of the applicable class of shares of the Fund.
    
   
    
     When the Fund  seeks  an  Independent  Trustee  to fill a  vacancy  or as a
nominee  for  election by  shareholders,  the  selection  or  nomination  of the
Independent   Trustee   is,   under   resolutions   adopted   by  the   Trustees
contemporaneously  with their adoption of the Plans, committed to the discretion
of the Committee on Administration of the Trustees. The members of the Committee
on  Administration  are all  Independent  Trustees  and are  identified  in this
Statement of Additional  Information  under the heading "Those  Responsible  for
Management."

NET ASSET VALUE

     For purposes of calculating the net asset value ("NAV") of a Fund's shares,
the following procedures are utilized wherever applicable.

     Debt investment  securities are valued on the basis of valuations furnished
by a  principal  market  maker or a  pricing  service,  both of which  generally
utilize electronic data processing techniques to determine valuations for normal
institutional  size trading units of debt securities  without exclusive reliance
upon quoted prices.

     Short-term debt investments  which have a remaining  maturity of 60 days or
less are generally valued at amortized cost which approximates  market value. If
market  quotations are not readily available or if in the opinion of the Adviser
any  quotation or price is not  representative  of true market  value,  the fair
value  of the  security  may be  determined  in good  faith in  accordance  with
procedures approved by the Trustees.

     Any assets or  liabilities  expressed  in terms of foreign  currencies  are
translated  into U.S.  dollars by the  custodian  bank based on London  currency
exchange  quotations as of 5:00 p.m., London time (12:00 noon, New York time) on
the date of any determination of a Fund's NAV.

     A Fund will not price its  securities on the following  national  holidays:
New Year's Day;  Presidents' Day; Good Friday;  Memorial Day;  Independence Day;
Labor Day;  Thanksgiving  Day; and  Christmas  Day. On any day an  international
market is closed and the New York Stock Exchange is open, any foreign securities
will be valued at the prior day's close with the current  day's  exchange  rate.
Trading of foreign  securities  may take place on  Saturdays  and U.S.  business
holidays  on  which a  Fund's  NAV is not  calculated.  Consequently,  a  Fund's
portfolio  securities may trade and the NAV of the Fund's redeemable  securities
may be  significantly  affected on days when a shareholder  has no access to the
Fund.


                                       21

INITIAL SALES CHARGE ON CLASS A SHARES
   
     The sales charges applicable to purchases of Class A shares of the Fund are
described in the Prospectus. Methods of obtaining reduced sales charges referred
to generally in the Prospectus are described in detail below. In calculating the
sales charge applicable to current purchases of Class A shares of the Fund owned
by the investor,  the investor is entitled to accumulate  current purchases with
the greater of the current  value (at  offering  price) of the Class A shares of
the Fund,  owned by the  investor or if, John  Hancock  Investor  Services  Inc.
(Investor  Services) is notified by the investor's dealer or the investor at the
time of the purchase, the cost of the Class A shares owned.
    
   
     Combined Purchases. In calculating the sales charge applicable to purchases
of Class A shares made at one time,  the  purchases  will be combined if made by
(a) an individual, his spouse and their children under the age of 21, purchasing
securities  for his or their  own  account,  (b) a  trustee  or other  fiduciary
purchasing  for a single  trust,  estate or  fiduciary  account  and (c) certain
groups of four or more  individuals  making use of salary  deductions or similar
group  methods of payment  whose funds are  combined  for the purchase of mutual
fund shares.  Further  information about combined  purchases,  including certain
restrictions on combined group purchases, is available from Investor Services or
a Selling Broker's representative.
    
     Without Sales Charges.  As described in the  Prospectus,  Class A shares of
the Fund may be sold without a sales charge to certain persons  described in the
Prospectus.

     Accumulation Privilege. Investors (including investors combining purchases)
who are already Class A shareholders  may also obtain the benefit of the reduced
sales charge by taking into account not only the amount then being  invested but
also the purchase  price or current value of the Class A shares  already held by
such person.
   
     Combination Privilege. Reduced sales charges (according to the schedule set
forth  in the  Prospectus)  also  are  available  to an  investor  based  on the
aggregate  amount of his concurrent  and prior  investments in Class A shares of
the Fund and shares of all other John Hancock funds which carry a sales charge.
    
   
     Letter of  Intention.  The reduced  sales  charges are also  applicable  to
investments  made over a specified period pursuant to a Letter of Intention (the
"LOI"),  which should be read  carefully  prior to its execution by an investor.
The  Fund  offers  two  options   regarding  the  specified  period  for  making
investments  under the LOI.  All  investors  have the  option  of  making  their
investments over a specified  period of thirteen (13) months.  Investors who are
using the Fund as a funding medium for a qualified retirement plan, however, may
opt to make the necessary  investments  called for by the LOI over a forty-eight
(48) month  period.  These  qualified  retirement  plans include group IRA, SEP,
SARSEP, TSA, 401(k), 403(b) and Section 457 plans. Such an investment (including
accumulations and combinations)  must aggregate $100,000 or more invested during
the specified  period from the date of the LOI or from a date within ninety (90)
days prior thereto, upon written request to Investor Services.  The sales charge
applicable to all amounts invested under the LOI is computed as if the aggregate
amount intended to be invested had been invested immediately.  If such aggregate
amount is not actually  invested,  the  


                                       22

<PAGE>

difference in the sales charge  actually  paid and the sales charge  payable had
the LOI not been in effect is due from the investor.  However, for the purchases
actually made within the specified  period the sales charge  applicable will not
be higher  than that  which  would have  applied  (including  accumulations  and
combinations) had the LOI been for the amount actually invested.
    
   
     The LOI authorizes  Investor  Services to hold in escrow sufficient Class A
shares  (approximately  5% of the  aggregate) to make up any difference in sales
charges on the amount intended to be invested and the amount actually  invested,
until such investment is completed  within the specified  period,  at which time
the escrow Class A shares will be released. If the total investment specified in
the LOI is not completed,  the Class A shares held in escrow may be redeemed and
the proceeds used as required to pay such sales charge as may be due. By signing
the  LOI,  the  investor  authorizes  Investor  Services  to  act  as his or her
attorney-in-fact  to redeem  any  escrowed  Class A shares  and adjust the sales
charge,  if  necessary.  A LOI does not  constitute a binding  commitment  by an
investor to purchase,  or by the Fund to sell, any additional Class A shares and
may be terminated at any time.
    

DEFERRED SALES CHARGE ON CLASS B SHARES

     Investments  in Class B shares are  purchased  at net asset value per share
without the  imposition of an initial sales charge so that the Fund will receive
the full amount of the purchase payment.

     Contingent Deferred Sales Charge.  Class B shares which are redeemed within
six years of purchase  will be subject to a  contingent  deferred  sales  charge
("CDSC") at the rates set forth in the  Prospectus as a percentage of the dollar
amount  subject to the CDSC.  The charge will be assessed on an amount  equal to
the lesser of the current  market  value or the  original  purchase  cost of the
Class B shares being redeemed. Accordingly, no CDSC will be imposed on increases
in account value above the initial  purchase  prices,  including  Class B shares
derived from reinvestment of dividends or capital gains distributions.
   
     The amount of the CDSC, if any, will vary  depending on the number of years
from the time of payment for the  purchase  of Class B shares  until the time of
redemption of such shares.  Solely for purposes of determining this number,  all
payments  during a month will be aggregated  and deemed to have been made on the
last day of the month.
    
   
     Proceeds from the CDSC are paid to John Hancock Funds and are used in whole
or in part by John  Hancock  Funds to defray its  expenses  related to providing
distribution-related  services  to the Fund in  connection  with the sale of the
Class B shares,  such as the payment of  compensation  to select Selling Brokers
for selling Class B shares. The combination of the CDSC and the distribution and
service  fees  facilitates  the  ability  of the Fund to sell the Class B shares
without a sales  charge  being  deducted  at the time of the  purchase.  See the
Prospectus for additional information regarding the CDSC.
    

                                       23
<PAGE>

SPECIAL REDEMPTIONS
   
     Although  it would not  normally  do so,  the Fund has the right to pay the
redemption  price  of  shares  of the  Fund in  whole  or in  part in  portfolio
securities as prescribed by the Trustees.  When the shareholder  sells portfolio
securities received in this fashion, he would incur a brokerage charge. Any such
securities  would be valued for the  purposes of making such payment at the same
value as used in determining net asset value. The Fund has, however,  elected to
be governed by Rule 18f-1 under the Investment Company Act. Under that rule, the
Fund must redeem its shares for cash  except to the extent  that the  redemption
payments to any shareholder  during any 90-day period would exceed the lesser of
$250,000 or 1% of the Fund's net asset value at the beginning of such period.
    
ADDITIONAL SERVICES AND PROGRAMS
   
     Exchange  Privilege.  As described more fully in the  Prospectus,  the Fund
permits  exchanges  of shares  of any  class of the Fund for  shares of the same
class in any other John Hancock fund offering that class.
    
   
     Systematic  Withdrawal  Plan. As described  briefly in the Prospectus,  the
Fund permits the establishment of a Systematic  Withdrawal Plan.  Payments under
this plan  represent  proceeds  from the  redemption  of Fund shares.  Since the
redemption  price of the Fund shares may be more or less than the  shareholder's
cost, depending upon the market value of the securities owned by the Fund at the
time of redemption, the distribution of cash pursuant to this plan may result in
realization  of gain or loss for  purposes  of Federal,  state and local  income
taxes.  The  maintenance  of a  Systematic  Withdrawal  Plan  concurrently  with
purchases  of  additional  Class A or  Class  B  shares  of the  Fund  could  be
disadvantageous to a shareholder  because of the initial sales charge payable on
such  purchases of Class A shares and the CDSC imposed on redemptions of Class B
shares and because  redemptions  are taxable  events.  Therefore,  a shareholder
should  not  purchase  Class A and Class B shares of the Fund at the same time a
Systematic  Withdrawal Plan is in effect.  The Fund reserves the right to modify
or discontinue  the Systematic  Withdrawal  Plan of any  shareholder on 30 days'
prior written notice to such shareholder,  or to discontinue the availability of
such plan in the future.  The  shareholder may terminate the plan at any time by
giving proper notice to Investor Services.
    
   
     Monthly Automatic Accumulation Program ("MAAP").  This program is explained
more fully in the Prospectus. The program, as it relates to automatic investment
checks, is subject to the following conditions:
    
   
     The investments will be drawn on or about the day of the month indicated.
    
   
     The  privilege  of  making   investments   through  the  Monthly  Automatic
Accumulation Program may be revoked by Investor Services without prior notice if
any investment is not honored by the shareholder's bank. The bank shall be under
no obligation to notify the shareholder as to the non-payment of any checks.
    

                                       24

<PAGE>

     The  program  may be  discontinued  by the  shareholder  either by  calling
Investor  Services or upon written notice to Investor Services which is received
at least five (5) business days prior to the processing date of any investment.
   
     Reinvestment  Privilege.  A  shareholder  who has redeemed Fund shares may,
within  120 days after the date of  redemption,  reinvest  without  payment of a
sales charge any part of the redemption  proceeds in shares of the same class of
the Fund or in any other John Hancock  fund,  subject to the minimum  investment
limit of that fund.  The proceeds  from the  redemption of Class A shares may be
reinvested at net asset value without paying a sales charge in Class A shares of
the Fund or in Class A shares of other John  Hancock  funds.  If a CDSC was paid
upon a redemption,  a shareholder may reinvest the proceeds from this redemption
at net asset value in additional  shares of the class from which the  redemption
was made. The shareholder's account will be credited with the amount of any CDSC
charged upon the prior redemption and the new shares will continue to be subject
to the CDSC.  The holding  period of the shares  acquired  through  reinvestment
will,  for purposes of computing the CDSC payable upon a subsequent  redemption,
include  the  holding  period of the  redeemed  shares.  The Fund may  modify or
terminate the reinvestment privilege at any time.
    
     A  redemption  or  exchange  of Fund  shares is a taxable  transaction  for
Federal income tax purposes even if the reinvestment privilege is exercised, and
any  gain  or  loss  realized  by a  shareholder  on  the  redemption  or  other
disposition  of Fund shares will be treated for tax purposes as described  under
the caption "Tax Status."

DESCRIPTION OF THE FUND'S SHARES
   
     The Trustees of the Fund are responsible for the management and supervision
of the Fund. The Declaration of Trust permits the Trustees to issue an unlimited
number of full and fractional shares of beneficial  interest of the Fund without
par value.  Under the  Declaration of Trust,  the Trustees have the authority to
create and classify shares of beneficial  interest in separate  series,  without
further action by  shareholders.  As of the date of this Statement of Additional
Information, the Trustees have not authorized any additional series of the Fund,
other than the Fund,  although they may do so in the future.  The Declaration of
Trust also  authorizes the Trustees to classify and reclassify the shares of the
Fund, or any other series of the Fund, into one or more classes.  As of the date
of this Statement of Additional  Information,  the Trustees have  authorized the
issuance of two classes of shares of the Fund, designated as Class A and Class B
shares.
    
   
     Class A and Class B shares  of the Fund  represent  an equal  proportionate
interest in the aggregate net assets attributable to that class of the Fund.
    
   
     The  holders of Class A shares and Class B shares  have  certain  exclusive
voting rights on matters  relating to their  respective Rule 12b-1  distribution
plans.
    
   
     Dividends  paid by the Fund,  if any,  with respect to each class of shares
will be calculated in the same manner,  at the same time and on the same day and
will be in the same amount,  except that (i) the  distribution  and service fees
relating to Class A and Class B shares will be borne  


                                       25

<PAGE>

exclusively by that class, (ii) Class B shares will pay higher  distribution and
service  fees than Class A shares  and (iii) each class of shares  will bear any
other class expenses properly  attributable to that class of shares,  subject to
the conditions  imposed by the Internal  Revenue  Service in issuing  rulings to
funds with multiple-class  structure.  Similarly,  the net asset value per share
may vary depending on the class of shares purchased.
    
   
     In the event of liquidation, shareholders are entitled to share pro rata in
the net assets of the Fund  available  for  distribution  to such  shareholders.
Shares entitle their holders to one vote per share, are freely  transferable and
have no preemptive  subscription or conversion rights.  When issued,  shares are
fully paid and non-assessable, by the Fund, except as set forth below.
    
     Unless otherwise  required by the Investment Company Act or the Declaration
of Trust,  the Fund has no intention of holding annual meetings of shareholders.
Fund  shareholders  may  remove a Trustee  by the  affirmative  vote of at least
two-thirds of the Fund's outstanding shares and the Trustees shall promptly call
a meeting  for such  purpose  when  requested  to do so in writing by the record
holders of not less than 10% of the outstanding shares of the Fund. Shareholders
may,  under  certain  circumstances,  communicate  with  other  shareholders  in
connection with requesting a special meeting of  shareholders.  However,  at any
time that less than a majority of the  Trustees  holding  office were elected by
the  shareholders,  the Trustees will call a special meeting of shareholders for
the purpose of electing Trustees.
   
     Under  Massachusetts  law,  shareholders of a Massachusetts  business trust
could,  under  certain  circumstances,  be held  personally  liable  for acts or
obligations of the Fund.  However,  the Fund's  Declaration of Trust contains an
express disclaimer of shareholder liability for acts,  obligations or affairs of
the Fund. The Declaration of Trust also provides for  indemnification out of the
Fund's  assets  for  all  losses  and  expenses  of any  Fund  shareholder  held
personally liable by reason of being or having been a shareholder.  Liability is
therefore  limited to  circumstances in which the Fund itself would be unable to
meet its obligations, and the possibility of this occurrence is remote.
    
TAX STATUS
   
     The Fund has  qualified  and has  elected  to be  treated  as a  "regulated
investment  company" under Subchapter M of the Internal Revenue Code of 1986, as
amended  (the  "Code"),  and intends to continue to so qualify for each  taxable
year.  As such and by  complying  with  the  applicable  provisions  of the Code
regarding  the sources of its income,  the timing of its  distributions  and the
diversification  of its assets,  the Fund will not be subject to Federal  income
tax on taxable income  (including net realized  capital gains,  if any) which is
distributed  to  shareholders  at least  annually in accordance  with the timing
requirements of the Code.
    
     The Fund will be subject to a four percent  non-deductible  Federal  excise
tax on  certain  amounts  not  distributed  (and  not  treated  as  having  been
distributed)  on a timely basis in accordance  with annual minimum  distribution
requirements. The Fund intends under normal circumstances to avoid liability for
such tax by satisfying such distribution requirements.


                                       26

<PAGE>

     Distributions  from the Fund's current or accumulated  earnings and profits
("E&P"),  as  computed  for  Federal  income  tax  purposes,  will be taxable as
described  in the  Fund's  Prospectus,  whether  taken  in  shares  or in  cash.
Distributions,  if any,  in excess of E&P will  constitute  a return of capital,
which will first reduce an  investor's  tax basis in Fund shares and  thereafter
(after such basis is reduced to zero) will generally give rise to capital gains.
Shareholders  electing to receive distributions in the form of additional shares
will have a cost basis for Federal income tax purposes in each share so received
equal to the amount of cash they would have received had they elected to receive
the distribution in cash, divided by the number of shares received.
   
     The amount of net realized  capital  gains,  if any, in any given year will
vary depending upon the Adviser's  current  investment  strategy and whether the
Adviser  believes  it to be in the  best  interest  of the  Fund to  dispose  of
portfolio  securities that will generate  capital gains or to enter into options
or futures transactions. At the time of an investor's purchase of Fund shares, a
portion of the purchase  price is often  attributable  to realized or unrealized
appreciation  in the Fund's  portfolio or  undistributed  taxable  income of the
Fund.   Consequently,   subsequent  distributions  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  in reality
represent a return of a portion of the purchase price.
    
   
     Upon a  redemption  of  shares  (including  by  exercise  of  the  exchange
privilege)  a  shareholder  will  ordinarily  realize  a  taxable  gain  or loss
depending  upon his basis in his  shares.  Such gain or loss will be  treated as
capital gain or loss if the shares are capital assets in the shareholder's hands
and will be  long-term  or  short-term,  depending  upon the  shareholder's  tax
holding period for the shares.  A sales charge paid in purchasing Class A shares
of the Fund cannot be taken into  account for  purposes of  determining  gain or
loss on the  redemption or exchange of such shares within ninety (90) days after
their  purchase to the extent Class A shares of the Fund or another John Hancock
fund are subsequently acquired without payment of a sales charge pursuant to the
reinvestment or exchange  privilege.  This disregarded  charge will result in an
increase in the  shareholder's  tax basis in the shares  subsequently  acquired.
Also,  any loss  realized on a redemption  or exchange may be  disallowed to the
extent the shares  disposed of are replaced with other shares of the Fund within
a period of  sixty-one  (61) days  beginning  thirty (30) days before and ending
thirty  (30) days after the shares are  disposed  of,  such as  pursuant  to the
Automatic  Dividend  Reinvestment  Plan. In such a case, the basis of the shares
acquired will be adjusted to reflect the disallowed loss. Any loss realized upon
the redemption 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.
    
     Although its present  intention is to distribute all net capital gains,  if
any,  the Fund  reserves  the right to retain and reinvest all or any portion of
the  excess,  as computed  for Federal  income tax  purposes,  of net  long-term
capital gain over net short-term  capital loss in any year. The Fund will not in
any event  distribute  net long-term  capital gains  realized in any year to the
extent that a capital  loss is carried  forward  from prior years  against  such
gain.  To  the  extent  such  excess  was  retained  and  not  exhausted  by the
carryforward  of prior  years'  capital  losses,  it would be subject to Federal
income  tax in the hands of the Fund.  Each  shareholder  would be  treated  for
Federal  income tax purposes as if the Fund had  distributed  to him on the last
day of its taxable year his 


                                       27

<PAGE>

pro rata share of such  excess,  and he had paid his pro rata share of the taxes
paid by the Fund and  reinvested  the remainder in the Fund.  Accordingly,  each
shareholder  would (a) include  his pro rata share of such  excess as  long-term
capital  gain in his  return for his  taxable  year in which the last day of the
Fund's taxable year falls,  (b) be entitled either to a tax credit on his return
for,  or to a refund of,  his pro rata share of the taxes paid by the Fund,  and
(c) be entitled to increase the adjusted tax basis for his shares in the Fund by
the difference  between his pro rata share of this excess and the pro rata share
of these taxes.
   
     For Federal  income tax purposes,  the Fund is permitted to  carryforward a
net capital  loss in any year to offset net capital  gains,  if any,  during the
eight years following the year of the loss. To the extent subsequent net capital
gains are offset by such  losses,  they  would not result in Federal  income tax
liability  to the  Fund  and,  as  noted  above,  would  not be  distributed  to
shareholders.  The Fund has $20,654,741 of capital loss carryforwards  available
to the extent  provided by  regulations,  to offset future net realized  capital
gains. These carryforwards expire at various amounts and times from 1996 through
2002.
    
     Distributions  from the Fund will not  qualify for the  dividends  received
deduction for corporations.

     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.

     The Fund may be subject to  withholding  and other taxes imposed by foreign
countries with respect to the Fund's investments in certain foreign  securities.
Tax conventions  between certain  countries and the U.S. may reduce or eliminate
such  taxes.  Because  more  than 50% of the  Fund's  assets at the close of any
taxable  year is not  expected  to  consist of stocks or  securities  of foreign
corporations,  the  Fund  will  not be able to pass  through  such  taxes to its
shareholders (as additional income) along with a corresponding  entitlement to a
tax  credit or  deduction.  The Fund will  deduct  such taxes in  computing  its
investment company taxable income.

     The Fund  accrues  income  on zero  coupon  securities  or  certain  PIK or
increasing rate securities (and, in general,  any other securities with original
issue  discount  or with market  discount  if the Fund elects to include  market
discount in income  currently)  prior to the receipt of cash payments.  The Fund
must distribute,  at least annually,  all or substantially all of its net 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.

     The Fund may  invest  in debt  obligations  that  are in the  lower  rating
categories or are unrated,  including debt  obligations of issuers not currently
paying  interest  as well as issuers  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  


                                       28

<PAGE>

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  reduce  the  risk of  distributing
insufficient income to preserve its status as a regulated investment company and
seek to avoid becoming subject to Federal income or excise tax.

     Limitations imposed by the Code on regulated  investment companies like the
Fund  may  restrict  the  Fund's  ability  to enter  into  futures  and  options
transactions.  The options and futures  transactions  undertaken by the Fund may
cause the Fund to  recognize  gains or losses from marking to market even though
its  positions  have not been sold or  terminated  and affect the  character  as
long-term or short-term and timing of some capital gains and losses  realized by
the Fund. Also, some of the Fund's losses on its transactions  involving options
and futures  contracts  and/or  offsetting  portfolio  positions may be deferred
rather than being taken into account currently in calculating the Fund's taxable
income. Some of the applicable tax rules may be modified if the Fund is eligible
and chooses to make one or more of certain tax elections  that may be available.
These transactions may thereafter affect the amount, timing and character of the
Fund's  distributions  to  shareholders.  The Fund will take  into  account  the
special tax rules (including consideration of available elections) applicable to
options and futures  transactions in order to minimize any potential adverse tax
consequences.

     The foregoing  discussion  relates solely to U.S. Federal income tax law as
applicable to U.S. persons (i.e.,  U.S.  citizens or residents and U.S. domestic
corporations,  partnerships,  trusts or estates)  subject to tax under such law.
The discussion does not address special tax rules  applicable to certain classes
of investors,  such as tax-exempt  entities,  insurance  companies and financial
institutions.  Dividends,  capital gain  distributions and ownership of or gains
realized on the  redemption  (including  an  exchange) of shares of the Fund may
also be subject to state and local  taxes.  A state income (and  possibly  local
income and/or intangible  property) tax exemption is generally  available to the
extent the Fund's distributions are derived from interest on (or, in the case of
intangibles  taxes,  the value of its assets is  attributable  to) certain  U.S.
Government  obligations,  provided in some states that  certain  thresholds  for
holdings of such obligations  and/or reporting  requirements are satisfied.  The
foregoing  discussion  related to U.S.  investors  that are not exempt from U.S.
Federal income tax.  Different tax consequences will apply to plan participants,
tax-exempt investors and investors that are subject to tax deferral.  You should
consult  your tax adviser for  specific  advice.  Under the Code,  a  tax-exempt
investor in the Fund will not generally  recognize  unrelated  business  taxable
income from its investment in the Fund unless the tax-exempt  investor  incurred
indebtedness  to acquire or continue  to hold Fund shares and such  indebtedness
remains  unpaid.  Shareholders  should  consult their own tax advisers as to the
Federal,  state or local tax consequences of ownership of shares of, and receipt
of distributions from, the Fund in their particular circumstances.

     Non-U.S. investors not engaged in a U.S. trade or business with which their
Fund investment is effectively  connected will be subject to U.S. Federal income
tax treatment that is different from that described  above.  These investors may
be subject to nonresident  alien  withholding tax at the rate of 30% (or a lower
rate under an applicable tax treaty),  on amounts treated as ordinary  dividends
from the Fund and, unless an effective IRS Form W-8 or authorized  


                                       29

<PAGE>

substitute is on file, to 31% backup  withholding on certain other payments from
the Fund.  Non-U.S.  investors should consult their tax advisors  regarding such
treatment and the application of foreign taxes to an investment in the Fund.

     The Fund is not  subject to  Massachusetts  corporate  excise or  franchise
taxes.  Provided that the Fund qualifies as a regulated investment company under
the Code, it will also not be required to pay any Massachusetts income tax.

CALCULATION OF PERFORMANCE
   
     For the 30-day  period ended  December 31, 1995,  the  annualized  yield on
Class A and Class B shares of the Fund was 5.88% and  5.46%,  respectively.  The
average  annual total return of the Class A shares of the Fund for the 1 year, 5
year and 10 year periods  ended  December 31, 1995 was 14.11%,  9.33% and 9.01%,
respectively and reflect payment of the maximum sales charge of 4.50%.
    
   
     The  average  annual  total  return of Class B shares of the Fund for the 1
year period ended December 31, 1995 and since inception on November 19, 1993 was
13.71% and 5.96%,  respectively.  The Fund's  yield is computed by dividing  net
investment  income  per share  determined  for a 30-day  period  by the  maximum
offering price per share (which  includes the full sales charge) on the last day
of the period, according to the following standard formula:

Where:

         a =      dividends and interest earned during the period.

         b =      net expenses accrued during the period.

         c =      the average daily number of fund shares outstanding during the
                  period that would be entitled to receive dividends.

         d =      the maximum offering price per share on the last day of the 
                  period (NAV where applicable).


                                       30

     The  Fund's  total  return  is  computed  by  finding  the  average  annual
compounded rate of return over the 1 year, 5 year and 10 year periods that would
equate the initial amount invested to the ending  redeemable  value according to
the following formula:

     n ______
T = \ / ERV/P - 1


Where:

       P =      a hypothetical initial investment of $1,000.

       T =      average annual total return.

       n =      number of years.

       ERV =    ending redeemable value of hypothetical $1,000 investment made
                at the beginning of the 1 year, 5 year and life-of-fund periods.
   
     In the case of Class A shares or Class B shares,  this calculation  assumes
the  maximum  sales  charge of 4.5% and 5.0%,  respectively,  is included in the
initial  investment  or the  CDSC  applied  at  the  end  of  the  period.  This
calculation also assumes that all dividends and  distributions are reinvested at
net asset value on the reinvestment dates during the period.
    
     In addition to average annual total returns,  the Fund may quote unaveraged
or  cumulative  total  returns  reflecting  the  simple  change  in  value of an
investment  over a stated  period.  Cumulative  total returns may be quoted as a
percentage or as a dollar amount, and may be calculated for a single investment,
a series of investments,  and/or a series of redemptions,  over any time period.
Total returns may be quoted with or without  taking the Fund's 4.5% sales charge
on  Class  A  shares  or the 5%  CDSC  on  Class  B  shares  into  account.  The
"distribution  rate" is  determined  by  annualizing  the result of dividing the
declared  dividends of the Fund during the period stated by the maximum offering
price or net asset value at the end of the period.  Excluding  the Fund's  sales
charge  on Class A shares  and the  CDSC on Class B shares  from a total  return
calculation produces a higher total return figure.
   
     From time to time, in reports and promotional literature,  the Fund's total
return  will be ranked or  compared  to indices  of mutual  funds such as Lipper
Analytical  Services,  Inc.'s "Lipper -Mutual  Performance  Analysis," a monthly
publication  which tracks net assets,  total return,  and yield on equity mutual
funds in the United States.  Ibottson and Associates,  CDA Weisenberger and F.C.
Towers  are also  used  for  comparison  purposes,  as well as the  Russell  and
Wilshire indices.
    
     Performance   rankings  and  ratings  reported   periodically  in  national
financial publications such as MONEY Magazine,  FORBES,  BUSINESS WEEK, THE WALL
STREET JOURNAL, MORNINGSTAR, and BARRON'S may also be utilized.

     The  performance  of the  Fund  is not  fixed  or  guaranteed.  Performance
quotations should not be considered to be  representations of performance of the
Fund for any period in the future.  The performance of the Fund is a function of
many factors including its earnings,  expenses and number of outstanding shares.
Fluctuating  market  conditions;  purchases,  sales and  maturities of portfolio
securities;  sales and redemptions of shares of beneficial interest; and changes
in  operating  expenses  are all examples of items that can increase or decrease
the Fund's performance.

BROKERAGE ALLOCATION

     Decisions  concerning the purchase and sale of portfolio securities and the
allocation  of  brokerage  commissions  are  made  by the  Adviser  pursuant  to
recommendations made by its investment committee, which consists of officers and
directors  of the Adviser and  affiliates,  and  officers  and  Trustees who are
interested persons of the Fund. Orders for purchases and sales of securities are
placed in a manner  which,  in the opinion of the  Adviser,  will offer the best
price and market for the  execution  of each such  transaction.  Purchases  from
underwriters  of portfolio  securities  may include a commission or  commissions
paid by the issuer  and  transactions  with  dealers  serving  as market  makers
reflect a "spread." Investments in debt securities are generally traded on a net
basis  through  dealers  acting for their own account as  principals  and not as
brokers; no brokerage commissions are payable on such transactions.

     The  Fund's  primary  policy  is to  execute  all  purchases  and  sales of
portfolio  instruments  at  the  most  favorable  prices  consistent  with  best
execution,  considering all of the costs of the transaction  including brokerage
commissions.  This policy  governs the  selection of brokers and dealers and the
market in which a transaction is executed. Consistent with the foregoing primary
policy,  the Rules of Fair  Practice of the National  Association  of Securities
Dealers, Inc. and such other policies as the Trustees may determine, the Adviser
may  consider  sales  of  shares  of the Fund as a factor  in the  selection  of
broker-dealers to execute the Fund's portfolio transactions.
   
     To the extent  consistent with the foregoing,  the Fund will be governed in
the  selection  of brokers and  dealers,  and in the  negotiation  of  brokerage
commission  rates and dealer  spreads,  by the  reliability  and  quality of the
services, including primarily the availability and value of research information
and to a lesser extent  statistical  assistance  furnished to the Adviser of the
Fund, and their value and expected  contribution to the performance of the Fund.
It is not  possible to place a dollar  value on  information  and services to be
received  from  brokers  and  dealers,  since  it is only  supplementary  to the
research  efforts of the  Adviser.  The receipt of research  information  is not
expected to reduce  significantly  the  expenses of the  Adviser.  The  research
information  and  statistical  assistance  furnished  by brokers and dealers may
benefit  the Life  Company  or  other  advisory  clients  of the  Adviser,  and,
conversely,  brokerage commissions and spreads paid by other advisory clients of
the  Adviser  may result in  research  information  and  statistical  assistance
beneficial to the Fund.  The Fund will make no commitment to allocate  portfolio
transactions  upon any  prescribed  basis.  While the Adviser  will be primarily
responsible for the allocation of the Fund's brokerage business,  their policies
and  practices  of the  Adviser  in this  regard  must be  consistent  with  the
foregoing  and will at all times be subject to review by the  Trustees.  For the



                                       32

<PAGE>

years ended on December  31,  1995,  1994,  and 1993,  no  negotiated  brokerage
commissions were paid on portfolio transactions.
    
   
     As permitted by Section 28(e) of the  Securities  Exchange Act of 1934, the
Fund may pay to a broker which provides  brokerage and research  services to the
Fund an amount of disclosed commission in excess of the commission which another
broker would have  charged for  effecting  that  transaction.  This  practice is
subject  to a good  faith  determination  by the  Trustees  that  such  price is
reasonable  in  light  of the  services  provided  and to such  policies  as the
Trustees may adopt from time to time.  During the fiscal year ended December 31,
1995,  the Fund did not pay  commissions  to  compensate  brokers  for  research
services  such as industry,  economic  and company  reviews and  evaluations  of
securities.
    
   
     The  Adviser's  indirect  parent,  the Life  Company,  is the indirect sole
shareholder of John Hancock Freedom Securities Corporation and its subsidiaries,
three of which, Tucker Anthony  Incorporated,  John Hancock  Distributors,  Inc.
("Distributors")  and Sutro &  Company,  Inc.,  ("Sutro")  each (an  "Affiliated
Broker"). Pursuant to procedures established by the Trustees and consistent with
the above policy of obtaining best net results,  the Fund may execute  portfolio
transactions with or through Affiliated Brokers. During the years ended December
31, 1995,  1994 and 1993,  the Fund did not execute any  portfolio  transactions
with Affiliated Brokers.
    
     Any of the  Affiliated  Brokers  may act as broker for the Fund on exchange
transactions,  subject,  however,  to the  general  policy of the Fund set forth
above and the  procedures  adopted by the  Trustees  pursuant to the  Investment
Company  Act.  Commissions  paid to an  Affiliated  Broker  must be at  least as
favorable as those which the connection with comparable  transactions  involving
similar  securities  being purchased or sold. A transaction  would not be placed
with an Affiliated  Broker if the Fund would have to pay a commission  rate less
favorable than the Affiliated  Broker's  contemporaneous  charges for comparable
transactions for its other most favored, but unaffiliated,  customers except for
accounts  for which the  Affiliated  Broker acts as of the  Trustees who are not
interested  persons (as defined in the Investment  Company Act) of the Fund, the
Adviser or the Affiliated Broker.  Because the Adviser, which is affiliated with
the  Affiliated  Brokers,  has,  as an  investment  adviser  to  the  Fund,  the
obligation to provide investment management services, which includes elements of
research and related  investment  skills,  such research and related skills will
not be used by the Affiliated Brokers as a basis for negotiating  commissions at
a rate higher than that determined in accordance  with the above  criteria.  The
Fund will not effect principal transactions with Affiliated Brokers.

TRANSFER AGENT SERVICES
   
     John Hancock Investor Services Corporation ("Investor Services"),  P.O. Box
9116,  Boston,  MA 02205-9116,  a wholly-owned  indirect  subsidiary of the Life
Company, is the transfer and dividend paying agent of the Fund. The Fund pays an
annual fee of $20.00  per  shareholder  for each Class A account  and $22.50 for
each Class B per shareholder account, plus certain out-of-pocket expenses. These
expenses are  aggregated  and charged to the Fund and allocated to each class on
the basis of the relative net asset values.

     penalties and other liabilities.

     However,  no indemnification  shall be provided to a Trustee or officer (i)
     against any liability to the Trust, a Series thereof or the Shareholders by
     reason of willful  misfeasance,  bad faith,  gross  negligence  or reckless
     disregard  of the duties  involved in the conduct of his office;  (ii) with
     respect to any matter as to which he shall  have been  finally  adjudicated
     not to have acted in good faith in the  reasonable  belief  that his action
     was in the best  interest  of the Trust or a Series  thereof;  (iii) in the
     event  of  a  settlement  or  other   disposition  not  involving  a  final
     adjudication  resulting in a payment by a Trustee or officer,  unless there
     has been a  determination  that such  Trustee or officer  did not engage in
     willful  misfeasance,  bad faith, gross negligence or reckless disregard of
     the duties  involved  in the  conduct of his office by (A) a court by (B) a
     majority of the Non- interested  trustees or independent legal counsel,  or
     (C) a vote of the majority of the Fund's outstanding shares.

     The rights of indemnification may be insured against by policies maintained
     by the Trust,  shall be  severable,  shall not  affect any other  rights to
     which any  Trustee or  officer  may now or  hereafter  be  entitled,  shall
     continue  as to a person who has ceased to be such  Trustee or officer  and
     shall  inure to the  benefit of the heirs,  executors,  administrators  and
     assigns of such a person.  Nothing contained herein shall affect any rights
     to  indemnification  to which  personnel of the Trust or any Series thereof
     other than  Trustees  and officers may be entitled by contract or otherwise
     under law.

     Expenses of preparation and presentation of a defense to any claim, action,
     suit or proceeding  may be advanced by the Trust or a Series thereof before
     final disposition, if the recipient undertakes to repay the amount if it is
     ultimately determined that he is not entitled to indemnification,  provided
     that either:

          (i)  such  undertaking  is  secured  by a  surety  bond or some  other
          appropriate security provided by the recipient, or the Trust or Series
          thereof  shall  be  insured  against  losses  arising  out of any such
          advances; or (ii) a majority of the Non-interested  Trustees acting on
          the matter  (provided that a majority of the  Non-interested  Trustees
          act on the  matter)  or an  independent  legal  counsel  in a  written
          opinion  shall  determine,  based upon a review of  readily  available
          facts (as opposed to a full trial-type inquiry),  that there is reason
          to believe that the  recipient  ultimately  will be found  entitled to
          indemnification.

          For purposes of indemnification Non-interested Trustee" is one who (i)
          is not an "Interested  Person" of the Trust (including  anyone who has
          been  exempted  from  being  an  "Interested   Person"  by  any  rule,
          regulation  or order of the  Commission),  and (ii) is not involved in
          the claim, action, suit or proceeding.

     (b) Under the Distribution Agreement.  Under Section 12 of the Distribution
Agreement,  John  Hancock  Funds,  Inc.  ("John  Hancock  Funds" ) has agreed to
indemnify the  Registrant  and its Trustees,  officers and  controlling  persons
against claims arising out of certain acts and statements of John Hancock Funds.

     Section 9(a) of the By-Laws of the Insurance Company  provides,  in effect,
that the Insurance Company will,  subject to limitations of law,  indemnify each
present  and former  director,  officer  and  employee  of the of the  Insurance
Company who serves as a Trustee or officer of the Registrant at the direction or
request of the Insurance  Company  against  litigation  expenses and liabilities
incurred while acting as such, except that such  indemnification  does not cover
any expense or liability incurred or imposed in connection with any matter as to
which such person shall be finally  adjudicated  not to have acted in good faith
in the  reasonable  belief  that his  action  was in the best  interests  of the
Insurance  Company.  In  addition,  no such  person will be  indemnified  by the
Insurance  Company in respect of any liability or expense incurred in connection
with any matter settled without final adjudication  unless such settlement shall
have been approved as in the best  interests of the Insurance  Company either by
vote of the Board of  Directors at a meeting  composed of directors  who have no
interest  in the  outcome of such  vote,  or by vote of the  policyholders.  The
Insurance  Company may pay expenses  incurred in defending an action or claim in
advance of its final disposition, but only upon receipt of an undertaking by the
person  indemnified  to repay  such  payment  if he should be  determined  to be
entitled to indemnification.

     Article IX of the respective  By-Laws of John Hancock Funds and the Adviser
provide as follows:

"Section  9.01.  Indemnity:  Any person made or threatened to be made a party to
any action,  suit or proceeding,  whether  civil,  criminal,  administrative  or
investigative,  by reason  of the fact  that he is or was at any time  since the
inception  of the  Corporation  serving at the request of the  Corporation  as a
director, officer, employee or agent of another corporation,  partnership, joint
venture,  trust or other  enterprise,  shall be indemnified  by the  Corporation
against expenses (including attorney's fees), judgments,  fines and amounts paid
in settlement  actually and reasonably  incurred by him in connection  with such
action,  suit or  proceeding if he acted in good faith and the liability was not
incurred  by reason of gross  negligence  or  reckless  disregard  of the duties
involved in the conduct of his office, and expenses in connection  therewith may
be advanced by the Corporation, all to the full extent authorized by the law."

"Section 9.02. Not Exclusive;  Survival of Rights: The indemnification  provided
by Section 9.01 shall not be deemed  exclusive of any other right to which those
indemnified may be entitled, and shall continue as to a person who has ceased to
be a director,  officer, employee or agent and shall inure to the benefit of the
heirs, executors and administrators of such as person."

Insofar as indemnification for liabilities under the Securities Act of 1933 (the
"Act")  may be  permitted  to  Trustees,  officers  and  controlling  persons of
Registrant  pursuant  to the  Registrant's  Amended  and  Restated  Articles  of
Incorporation,  Article  10.1  of the  Registrant's  By-Laws,  The  underwriting
Agreement,  the By-Laws of John Hancock  Funds,  the Adviser,  or the  Insurance
Company or  otherwise,  Registrant  has been  advised that in the opinion of the
Securities and Exchange  Commission  such  indemnification  is against policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for  indemnification  against  such  liabilities  (other than the payment by the
Registrant  in the  successful  defense of any action,  suit or  proceeding)  is
asserted by such Trustee,  officer or controlling  person in connection with the
securities  being  registered,  Registrant  will,  unless in the  opinion of its
counsel the matter has been settled by controlling precedent,  submit to a court
of  appropriate  jurisdiction  the  question  whether  indemnification  by it is
against  public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

     except  a loss  resulting  from  willful  misfeasance,  bad  faith or gross
     negligence on your part in the  performance of your duties or from reckless
     disregard by you of your  obligations and duties under this Agreement.  Any
     person,  even though also employed by you, who may be or become an employee
     of and paid by the Funds shall be deemed,  when acting  within the scope of
     his or her employment by the Funds, to be acting in such employment  solely
