To Our Shareholders,

I am pleased to be writing to you as the new President and Chief Executive
Officer of John Hancock Funds, LLC, following the departure of James A.
Shepherdson to pursue other opportunities. In addition, on July 25, 2005,
your fund's Board of Trustees appointed me to the roles of President and
Chief Executive Officer of your fund.

As a means of introduction, I have been involved in the mutual fund
industry since 1985. I have been with John Hancock Funds for the last 15
years, most recently as executive vice president of retail sales and
marketing and a member of the company's executive and investment
committees. In my former capacity, I was responsible for all aspects of
the distribution and marketing of John Hancock Funds' open-end and
closed-end mutual funds. Outside of John Hancock, I have served as
Chairman of the Investment Company Institute (ICI) Sales Force Marketing
Committee since September 2003.

It is an exciting time to be at John Hancock Funds, and I am grateful for
the opportunity to lead and shape its future growth. With the acquisition
of John Hancock by Manulife Financial Corporation in April 2004, we are
receiving broad support toward the goal of providing our shareholders with
excellent investment opportunities and a more complete lineup of choices
for the discerning investor.

As you may have read, John Hancock recently entered into an agreement with
GMO, a Boston-based institutional money manager, to acquire eight of their
mutual funds. In addition, we are in the process of adding five "Lifestyle
Portfolio" funds-of-funds that blend multiple fund offerings from internal
and external money managers to create a broadly diversified asset
allocation portfolio. Look for more information about these exciting
additions to the John Hancock family of funds in your fourth quarter
shareholder newsletter.

Although there has been a change in executive-level management, rest
assured that the one thing that never wavers is John Hancock Funds'
commitment to placing the needs of shareholders above all else. We are all
dedicated to the task of working with you and your financial advisors to
help you reach your long-term financial goals.

Sincerely,

/s/ Keith F. Hartstein

Keith F. Hartstein,
President and Chief Executive Officer

YOUR FUND
AT A GLANCE

The Fund seeks a
high level of current
income consistent
with prudent
investment risk by
investing at least
80% of its assets in a
diversified portfolio
of income securities.

Over the last six months

* Despite further interest rate increases by the Federal Reserve, bonds
  gained ground amid tame inflation and mixed economic data.

* Treasury and government agency bonds were the best performers, while
  corporate bonds lagged.

* The Fund benefited from its exposure to higher-quality bonds, but its
  reduced interest rate sensitivity hindered performance as bond yields
  declined.

BY BARRY H. EVANS, CFA, AND JEFFREY N. GIVEN, CFA, PORTFOLIO MANAGERS

MANAGERS'
REPORT

JOHN HANCOCK
Income Securities Trust

The U.S. bond market confounded expectations during the first six months
of 2005, as yields generally declined and bonds posted positive returns
overall. Bonds rallied despite a series of interest rate increases by the
Federal Reserve. The Fed raised its federal funds rate target by a
quarter-point four times in the first half of 2005, for a total of nine
rate hikes since June 2004. The federal funds rate ended the period at
3.25%, its highest level in nearly four years.

Although short-term bond yields rose in response to the Fed's actions --
the two-year Treasury note yield climbed from 3.1% to 3.6% -- longer-term
bond yields declined during the six-month period. Low inflation and mixed
economic data, which suggested that the Fed may end its rate-raising cycle
sooner than originally anticipated, were the main reasons behind the rally
in the long end of the bond market.

"The U.S. bond market con-
 founded expectations during the
 first six months of 2005, as yields
 generally declined and bonds
 posted positive returns
 overall."

The Lehman Brothers U.S. Aggregate Index -- a broad measure of the U.S.
bond market -- returned 2.51% in the first half of 2005. Treasury bonds,
which tend to benefit the most from declining interest rates, posted the
best results. Corporate bonds, the top performers in 2003 and 2004, lagged
the rest of the bond market. In particular, high-yield corporate bonds
produced nearly flat returns during the period.

Fund performance

For the six months ended June 30, 2005, John Hancock Income Securities
Trust produced a total return of 1.30% at net asset value (NAV) and
- -0.03% at market value. The Fund's NAV return and its market performance
differ because the market share price is subject to the dynamics of
secondary market trading, which could cause it to trade at a discount or
premium to the Fund's NAV share

price at any time. For comparison, the average closed-end BBB-rated
corporate debt fund returned 2.77% at net asset value, according to
Lipper, Inc., while the Lehman Brothers Government/Credit Bond Index
returned 2.75%.

Staying defensive

In our last report six months ago, we discussed our efforts to establish a
more defensive position for the portfolio, reducing its risk profile
through higher credit quality and less interest rate sensitivity. We
maintained this defensive positioning throughout the first half of 2005,
making few changes to the overall structure of the portfolio.

The portfolio benefited from its exposure to higher-quality bonds as they
outperformed lower-rated securities. However, the portfolio's reduced
sensitivity to interest rate fluctuations hindered performance, thanks to
the unexpected decline in longer-term bond yields during the period. The
lower rate sensitivity, along with an underweight in Treasury bonds, led
to the portfolio's underperformance of its Lipper peer group and the
Lehman index.

Better quality, same yield

The few changes we made to the portfolio during the period involved
upgrading credit quality by selling some of our lower-rated corporate
bonds and adding more government agency and mortgage-backed securities to
the portfolio. We focused on callable government agency securities
maturing in two to three years. These AAA-rated bonds offered yields that
were equal to or higher than BBB-rated corporate bonds with similar
maturities, so we were able to trade up in credit quality without giving
up any yield.

"The best individual performers in
 the portfolio were longer-term,
 higher-quality bonds."

In the mortgage-backed market, we invested in adjustable-rate mortgages,
which reset their interest rates at regular intervals. These short-term
bonds also carry AA or AAA ratings and offered higher yields than
similar-maturity corporate bonds.

Energy, telecom bonds perform well

The best individual performers in the portfolio were longer-term,
higher-quality bonds. One example was Alberta Energy, an A-rated


3



Canadian oil exploration and production company. Soaring oil prices
provided a lift to Alberta Energy bonds, and the long maturity date (in
2030) allowed them to participate in the general rally in long-term bonds.

seventh is Consumer discretionary 5%, the eighth is Materials 3%, the ninth
is Consumer staples 3%, the tenth is Energy 2%, the eleventh is Health care
2% and the twelfth is Government - foreign 1%.]

Another top performer was telecommunication services provider Sprint,
which recently entered into a merger agreement with Nextel. In addition to
their long maturity, Sprint bonds benefited from consolidation in the
wireless industry, which is expected to improve pricing power for wireless
service providers going forward.

Autos hit the skids

The weakest performers in the portfolio were bonds issued by the major
U.S. automakers, General Motors and Ford. Disappointing auto sales,
increased competition and higher gas prices caused GM to warn of lower
earnings, and its credit rating was cut to below-investment-grade status.
Ford, facing similar struggles, teetered on the edge of its own credit
downgrade (which we expect to occur in the next few months). The
downgrades caused sharp declines in the value of their bonds.

[Pie chart at middle of page with heading "Portfolio diversification 1."
The chart is divided into four sections (from top to left): Bonds 55%, U.S.
government & agency bonds 39%, Preferred stocks 5% and Short-term
investments & other 1%.]

We owned a modest amount of both GM and Ford (less than 2% of the
portfolio combined), and our holdings were all shorter-term securities --
Ford Motor Credit bonds maturing in 2009 and GMAC bonds maturing in 2011.
Nonetheless, these securities declined by about 10% during the period.
However, we are confident about the creditworthiness of these shorter-term
bonds and intend to maintain our positions.

Outlook

The U.S. economy, which grew by 4.4% in 2004, is slowing to a more
moderate growth rate in 2005. In addition, the inflation rate has remained
tame despite higher oil prices, and the dollar is strengthening after
several years of weakness. Consequently, we think most of the Fed's work
is done. We expect one or two more rate hikes in the coming months,
followed by a period of stability.

[Table at top of page entitled "SCORECARD." The header for the left column
is "INVESTMENT" and the header for the right column is "PERIOD'S
PERFORMANCE...AND WHAT'S BEHIND THE NUMBERS." The first listing is
Long-term Treasury bonds followed by an up arrow with the phrase "The
longest-term Treasury bond returned 11% as interest rates declined." The
second listing is Barclays Bank followed by an up arrow with the phrase
"AA-rated, long-term security benefited from flight to quality." The third
listing is Qwest followed by a down arrow with the phrase "Repeated
attempts to outbid Verizon in order to acquire MCI disappointed
investors."]

Given the moderate economic and inflationary environment, we don't expect
bond yields to rise significantly in the second half of 2005. The spreads
between corporate bond yields and Treasury yields remain near historically
low levels, but modest issuance in the corporate bond market and strong
corporate balance sheets should help keep spreads from widening
substantially. We continue to find many attractive investment
opportunities in the corporate bond market.

"Given the moderate economic
and inflationary environment, we
don't expect bond yields to rise
significantly in the second half
of 2005."

Within the portfolio, we intend to maintain our current positioning going
forward. If interest rates rise sharply, we may look to increase the
portfolio's interest rate sensitivity.

Notes to Financial Highlights

 1 Audited by previous auditor.

 2 As required, effective January 1, 2001, the Fund has adopted the
   provisions of the AICPA Audit and Accounting Guide for Investment
   Companies, as revised, relating to the amortization of premiums and
   accretion of discounts on debt securities. The effect of this change on
   per share amounts for the year ended December 31, 2001, was to decrease
   net investment income per share by $0.02, increase net realized and
   unrealized gain per share by $0.02 and, had the Fund not made these
   changes to amortization and accretion, the ratio of net investment income
   to average net assets would have been 6.30%. Per share ratios and
   supplemental data for periods prior to January 1, 2001, have not been
   restated to reflect this change in presentation.

 3 Semiannual period from 1-1-05 through 6-30-05. Unaudited.

 4 Based on the average of the shares outstanding.

 5 APS Series A and B were issued on 11-4-03.

 6 Assumes dividend reinvestment.

 7 Not annualized.

 8 Ratios calculated on the basis of expenses relative to the average net
   assets of common shares. Without the exclusion of preferred shares, the
   annualized ratios of expenses would have been 0.81%, 0.76% and 0.75% for
   the periods ended 12-31-03, 12-31-04 and 6-30-05, respectively.

 9 Annualized.

10 Ratios calculated on the basis of net investment income relative to the
   average net assets of common shares. Without the exclusion of preferred
   shares, the annualized ratios of net investment income would have been
   5.19%, 4.99% and 5.09% for the periods ended 12-31-03, 12-31-04 and
   6-30-05, respectively.

11 Calculated by subtracting the Fund's total liabilities from the Fund's
   total assets and dividing that amount by the number of APS outstanding, as
   of the applicable 1940 Act Evaluation Date, which may differ from the
   financial reporting date.

NOTES TO
STATEMENTS

Unaudited

Note A
Accounting policies

John Hancock Income Securities Trust (the "Fund") is a closed-end
diversified investment management company registered under the Investment
Company Act of 1940.

Significant accounting policies
of the Fund are as follows:

Valuation of investments

Securities in the Fund's portfolio are valued on the basis of market
quotations, valuations provided by independent pricing services or at fair
value as determined in good faith in accordance with procedures approved
by the Trustees. Short-term debt investments which have a remaining
maturity of 60 days or less may be valued at amortized cost, which
approximates market value. The Fund determines the net asset value of the
common shares each business day.

Joint repurchase agreement

Pursuant to an exemptive order issued by the Securities and Exchange
Commission, the Fund, along with other registered investment companies
having a management contract with John Hancock Advisers, LLC (the
"Adviser"), a wholly owned subsidiary of John Hancock Financial Services,
Inc., may participate in a joint repurchase agreement transaction.
Aggregate cash balances are invested in one or more large repurchase
agreements, whose underlying securities are obligations of the U.S.
government and/or its agencies. The Fund's custodian bank receives
delivery of the underlying securities for the joint account on the Fund's
behalf. The Adviser is responsible for ensuring that the agreement is
fully collateralized at all times.

Investment transactions

Investment transactions are recorded as of the date of purchase, sale or
maturity. Net realized gains and losses on sales of investments are
determined on the identified cost basis. Some securities may be purchased
on a "when issued" or "forward delivery" basis, which means that the
securities will be delivered to the Fund at a future date, usually beyond
the customary settlement date.

Discount and premium
on securities

The Fund accretes discount and amortizes premium from par value on
securities from either the date of issue or the date of purchase over the
life of the security.

Expenses

The majority of the expenses are directly identifiable to an individual
fund. Expenses that are not readily identifiable to a specific fund will
be allocated in such a manner as deemed equitable, taking into
consideration, among other things, the nature and type of expense and the
relative sizes of the funds.

Securities lending

The Fund may lend securities to certain qualified brokers who pay


24



the Fund negotiated lender fees. The loans are collateralized at all times
with cash or securities with a market value at least equal to the market
value of the securities on loan. As with other extensions of credit, the
Fund may bear the risk of delay of the loaned securities in recovery or
even loss of rights in the collateral, should the borrower of the
securities fail financially. On June 30, 2005, the Fund loaned securities
having a market value of $31,942,801 collateralized by securities in the
amount of $32,292,636. Securities lending expenses are paid by the Fund to
the Adviser.

Financial futures contracts

The Fund may buy and sell financial futures contracts. Buying futures
tends to increase the Fund's exposure to the underlying instrument.
Selling futures tends to decrease the Fund's exposure to the underlying
instrument or hedge other Fund's instruments. At the time the Fund enters
into financial futures contracts, it is required to deposit with its
custodian a specified amount of cash or U.S. government securities, known
as "initial margin," equal to a certain percentage of the value of the
financial futures contract being traded. Each day, the futures contract is
valued at the official settlement price of the board of trade or U.S.
commodities exchange on which it trades. Subsequent payments to and from
the broker, known as "variation margin," are made on a daily basis as the
market price of the financial futures contract fluctuates. Daily variation
margin adjustments arising from this "mark to market" are recorded by the
Fund as unrealized gains or losses.

When the contracts are closed, the Fund recognizes a gain or loss. Risks
of entering into financial futures contracts include the possibility that
there may be an illiquid market and/or that a change in the value of the
contracts may not correlate with changes in the value of the underlying
securities. In addition, the Fund could be prevented from opening or
realizing the benefits of closing out financial futures positions because
of position limits or limits on daily price fluctuation imposed by an
exchange.

For federal income tax purposes, the amount, character and timing of the
Fund's gains and/or losses can be affected as a result of financial
futures contracts.

On June 30, 2005, the Fund had deposited $402,750 in a segregated account
to cover margin requirements on open financial futures contracts.

The Fund had the following financial futures contracts open on June 30, 2005:

U.S. 10-Year Treasury Note   32          Short      Sep 05           (24,724)

Federal income taxes

The Fund qualifies as a "regulated investment company" by complying with
the applicable provisions of the Internal Revenue Code and will not be
subject to federal income tax on taxable income that is distributed to
shareholders. Therefore, no federal income tax provision is required. For
federal income tax purposes, the Fund has $2,123,466 of a capital loss
carryforward available, to the extent provided by regulations, to offset
future net realized capital gains. To the extent that such carryforward is
used by the Fund, no capital gain distributions will be made. The entire
amount of the loss carryforward expires December 31, 2012.


25



Dividends, interest
and distributions

Dividend income on investment securities is recorded on the ex-dividend
date or, in the case of some foreign securities, on the date thereafter
when the Fund identifies the dividend. Interest income on investment
securities is recorded on the accrual basis. The Fund may place a debt
obligation on non-accrual status and reduce related interest income by
ceasing current accruals and writing off interest receivables when the
collection of interest has become doubtful. Foreign income may be subject
to foreign withholding taxes, which are accrued as applicable.

The Fund records distributions to shareholders from net investment income
and net realized gains, if any, on the ex-dividend date. During the year
ended December 31, 2004, the tax character of distributions paid was as
follows: ordinary income $14,478,047.

Such distributions, on a tax basis, are determined in conformity with
income tax regulations, which may differ from accounting principles
generally accepted in the United States of America. Distributions in
excess of tax basis earnings and profits, if any, are reported in the
Fund's financial statements as a return of capital.

Use of estimates

The preparation of these financial statements, in accordance with
accounting principles generally accepted in the United States of America,
incorporates estimates made by management in determining the reported
amount of assets, liabilities, revenues and expenses of the Fund. Actual
results could differ from these estimates.

Note B
Management fee and
transactions with
affiliates and others

The Fund has an investment management contract with the Adviser. Under the
investment management contract, the Fund pays a quarterly management fee
to the Adviser, equivalent on an annual basis, to the sum of (a) 0.650% of
the first $150,000,000 of the Fund's average weekly net asset value and
the value attributable to the Auction Preferred Shares (collectively,
"managed assets"), (b) 0.375% of the next $50,000,000, (c) 0.350% of the
next $100,000,000 and (d) 0.300% of the Fund's average daily managed
assets in excess of $300,000,000.

The Fund has an agreement with the Adviser to perform necessary tax,
accounting and legal services for the Fund. The compensation for the
period amounted to $27,522. The Fund also paid the Adviser the amount of
$4,037 for certain compliance costs, included in the miscellaneous
expenses.

The compensation of unaffiliated Trustees is borne by the Fund. The
unaffiliated Trustees may elect to defer, for tax purposes, their receipt
of this compensation under the John Hancock Group of Funds Deferred
Compensation Plan. The Fund makes investments into other John Hancock
funds, as applicable, to cover its liability for the deferred
compensation. Investments to cover the Fund's deferred compensation
liability are recorded on the Fund's books as an other asset. The deferred
compensation liability and the related other asset are always equal and
are marked to market on a periodic basis to reflect any income earned by
the investments, as well as any unrealized gains or losses. The Deferred
Compensation Plan investments had no impact on the operations of the Fund.

The Fund is listed for trading on the New York Stock Exchange ("NYSE") and
has filed with the NYSE its chief executive officer certification
regarding compliance with the NYSE's listing standards. The Fund also
files with the Securities and Exchange Commission the certification of its
chief executive officer and chief accounting officer required by Section
302 of the Sarbanes-Oxley Act.

Auction preferred shares

The Fund issued a total of 3,560 Auction Preferred Shares: 1,780 shares of
Series A Auction Preferred Shares and 1,780 shares of Series B Auction
Preferred Shares (collectively, the "Preferred Shares" or "APS") on
November 4, 2003, in a public offering. The total offering costs of
$188,388 and the total underwriting discount of $890,000 has been charged
to capital paid-in of common shares during the years ended December 31,
2003 and December 31, 2004.

Dividends on the APS, which accrue daily, are cumulative at a rate that
was established at the offering of the APS and has been reset every 7 days
thereafter by an auction. Dividend rates on APS Series A ranged from 2.10%
to 3.40% and Series B from 2.24% to 3.45% during the period ended June 30,
2005. Accrued dividends on APS are included in the value of APS on the
Fund's Statement of Assets and Liabilities.

The APS are redeemable at the option of the Fund, at a redemption price
equal to $25,000 per share, plus accumulated and unpaid dividends on any
dividend payment date. The APS are also subject to mandatory redemption at
a redemption price equal to $25,000 per share, plus accumulated and unpaid
dividends, if the Fund is in default on its asset coverage requirements
with respect to the APS as defined in the Fund's by-laws. If the dividends
on the APS shall remain unpaid in an amount equal to two full years'
dividends, the holders of the APS, as a class, have the right to elect a
majority of the Board of Trustees. In general, the holders of the APS and
the common shareholders have equal voting rights of one vote per share,
except that the holders of the APS, as a class, vote to elect two members
of the Board of Trustees, and separate class votes are required on certain
matters that affect the respective interests of the APS and common
shareholders.

Note D
Investment
transactions

Purchases and proceeds from sales or maturities of securities, other than
short-term securities and obligations of the U.S. government, during the
period ended June 30, 2005, aggregated $118,105,102 and $107,531,247,
respectively. Purchases and proceeds from sales or maturities of
obligations of U.S. government aggregated $50,836,745 and $54,136,215,
respectively, during the period ended June 30, 2005.

The cost of investments owned on June 30, 2005, including short-term
investments, for federal income tax purposes was $270,587,813.


27



Gross unrealized appreciation and depreciation of investments aggregated
$6,905,067 and $2,834,521, respectively, resulting in net unrealized
appreciation of $4,070,546. The difference between book basis and tax
basis net unrealized appreciation of investments is attributable primarily
to the tax deferral of losses on certain sales of securities and
amortization of premiums on debt securities.


28



Investment
objective
and policy

The Fund is a closed-end diversified management investment company, common
shares of which were initially offered to the public on February 14, 1973,
and are publicly traded on the New York Stock Exchange. The Fund's
investment objective is to generate a high level of current income
consistent with prudent investment risk. The Fund invests in a diversified
portfolio of freely marketable debt securities and may invest an amount
not exceeding 20% of its assets in income-producing preferred and common
stock. Under normal circumstances, the Fund will invest at least 80% of
net assets in income securities. Income securities will consist of the
following: (i) marketable corporate debt securities, (ii) governmental
obligations and (iii) cash and commercial paper. "Net assets" is defined
as net assets plus borrowings for investment purposes. The Fund will
notify shareholders at least 60 days prior to any change in this 80%
investment policy.

It is contemplated that at least 75% of the value of the Fund's total
assets will be represented by debt securities, which have at the time of
purchase a rating within the four highest grades as determined by Moody's
Investors Service, Inc., or Standard & Poor's Corporation. The Fund
intends to engage in short-term trading and may invest in repurchase
agreements. The Fund may issue a single class of senior securities not to
exceed 331/3% of its net assets at market value and may borrow from banks
as a temporary measure for emergency purposes in amounts not to exceed 5%
of the total assets at cost. The Fund may lend portfolio securities not to
exceed 331/3% of total assets.

By-laws

In November 2002, the Board of Trustees adopted several amendments to the
Fund's by-laws, including provisions relating to the calling of a special
meeting and requiring advance notice of shareholder proposals or nominees
for Trustee. The advance notice provisions in the by-laws require
shareholders to notify the Fund in writing of any proposal which they
intend to present at an annual meeting of shareholders, including any
nominations for Trustee, between 90 and 120 days prior to the first
anniversary of the mailing date of the notice from the prior year's annual
meeting of shareholders. The notification must be in the form prescribed
by the by-laws. The advance notice provisions provide the Fund and its
Trustees with the opportunity to thoughtfully consider and address the
matters proposed before the Fund prepares and mails its proxy statement to
shareholders. Other amendments set forth the procedures, which must be
followed in order for a shareholder to call a special meeting of
shareholders. Please contact the Secretary of the Fund for additional
information about the advance notice requirements or the other amendments
to the by-laws.

On August 21, 2003, shareholders approved the amendment of the Fund's
by-laws effective August 26, 2003, to provide for the issuance of
preferred shares. Effective March 9, 2004, the Trustees approved
additional changes to conform with the Fund's maximum dividend rate on the
preferred shares with the rate used by other John Hancock funds.

On September 14, 2004, the Trustees approved an amendment to the Fund's
by-laws increasing the maximum applicable dividend rate ceiling on the
preferred shares to conform with the modern calculation methodology used
by the industry and other John Hancock funds.

Financial futures
contracts and options

The Fund may buy and sell financial futures contracts and options on
futures contracts to hedge against the effects of fluctuations in interest
rates and other market conditions. The Fund's ability to hedge
successfully


29



will depend on the Adviser's ability to predict accurately the future
direction of interest rate changes and other market factors. 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.

The Fund will not engage in transactions in futures contracts and options
on futures for speculation, but only for hedging or other permissible risk
management purposes. All of the Fund's futures contracts and options on
futures will be traded on a U.S. commodity exchange or board of trade. The
Fund will not engage in a transaction in futures or options on futures if,
immediately thereafter, the sum of initial margin deposits on existing
positions and premiums paid for options on futures would exceed 5% of the
Fund's total assets.

Dividends and
distributions

The Fund pays quarterly dividends from net investment income and intends
to distribute any available net realized capital gains annually. All
distributions are paid in cash unless the shareholder elects to
participate in the Dividend Reinvestment Plan.

During the period ended June 30, 2005, the Fund paid to shareholders
dividends from net investment income totaling $0.540 per share. The dates
of payments and the amounts per share are as follows:

                          INCOME
PAYMENT DATE            DIVIDEND
- --------------------------------
March 31, 2005            $0.280
June 30, 2005              0.260

Dividend
reinvestment plan

The Fund offers its common shareholders a Dividend Reinvestment Plan (the
"Plan"), which offers the opportunity to earn compounded yields. Any
holder of common shares of record of the Fund may elect to participate in
the Plan and receive the Fund's common shares in lieu of all or a portion
of the cash dividends. The Plan is available to all common shareholders
without charge. Mellon Investor Services (the "Plan Agent") will act as
agent for participating shareholders.

Shareholders may join the Plan by notifying the Plan Agent by telephone,
in writing or by visiting the Plan Agent's Web site at
www.melloninvestor.com showing an election to reinvest all or a portion of
dividend payments. If received in proper form by the Plan Agent prior to
the record date for a dividend, the election will be effective with
respect to all dividends paid after such record date. Shareholders whose
shares are held in the name of a broker or nominee should contact the
broker or nominee to determine whether and how they may participate in the
Plan.

The Board of Trustees of the Fund will declare dividends from net
investment income payable in cash or, in the case of shareholders
participating in the Plan, partially or entirely in the Fund's common
shares. The number of shares to be issued for the benefit of each
shareholder will be determined by dividing the amount of the cash dividend
otherwise, payable to such shareholder on shares included under the Plan,
by the per share net asset value of the common shares on the date for
payment of the dividend, unless the net asset value per share on the
payment date is less than 95% of the market price per share on that date,
in which event the number of shares to be issued to a shareholder will be
determined by dividing the amount of the cash dividend payable to such
shareholder, by 95% of the market price per share of the common shares on
the payment date. The market price of the common shares on a particular
date shall be the mean between the highest and lowest sales price on the
New York Stock Exchange on that date. Net asset


30



value will be determined in accordance with the established procedures of
the Fund. However, if as of such payment date the market price of the
common shares is lower than such net asset value per share, the number of
shares to be issued will be determined on the basis of such market price.
Fractional shares, carried out to four decimal places, will be credited to
the shareholder's account. Such fractional shares will be entitled to
future dividends.

The shares issued to participating shareholders, including fractional
shares, will be held by the Plan Agent in the name of the participant. A
confirmation will be sent to each shareholder promptly, normally within
five to seven days, after the payment date of the dividend. The
confirmation will show the total number of shares held by such shareholder
before and after the dividend, the amount of the most recent cash dividend
that the shareholder has elected to reinvest and the number of shares
acquired with such dividend.

Participation in the Plan may be terminated at any time by contacting the
Plan Agent by telephone, in writing or by visiting the Plan Agent's Web
site, and such termination will be effective immediately. However, notice
of termination must be received prior to the record date of any
distribution to be effective for that distribution. Upon termination,
certificates will be issued representing the number of full shares of
common shares held by the Plan Agent. A shareholder will receive a cash
payment for any fractional share held.

The reinvestment of dividends will not relieve participants of any
federal, state or local income tax, which may be due with respect to such
dividend. Dividends reinvested in common shares will be treated on your
federal income tax return as though you had received a dividend in cash in
an amount equal to the fair market value of the shares received, as
determined by the prices for common shares of the Fund on the New York
Stock Exchange as of the dividend payment date. Distributions from the
Fund's long-term capital gains will be processed as noted above for those
electing to reinvest in common shares and will be taxable to you as
long-term capital gains. The confirmation referred to above will contain
all the information you will require for determining the cost basis of
shares acquired and should be retained for that purpose. At year end, each
account will be supplied with detailed information necessary to determine
total tax liability for the calendar year.

All correspondence or additional information concerning the Plan should be
directed to the Plan Agent, Mellon Bank, N.A., c/o Mellon Investor
Services, P.O. Box 3338, South Hackensack, New Jersey 07606-1938

Board Consideration
of and Continuation
of Investment
Advisory Agreement

Section 15(c) of the Investment Company Act of 1940 (the "1940 Act")
requires the Board of Trustees (the "Board") of John Hancock Income
Securities Trust (the "Fund"), including a majority of the Trustees who
have no direct or indirect interest in the investment advisory agreement
and are not "interested persons" of the Fund, as defined in the 1940 Act
(the "Independent Trustees"), annually to review and consider the
continuation of the investment advisory agreement (the "Advisory
Agreement") with John Hancock Advisers, LLC (the "Adviser") for the Fund.

At meetings held on May 19-20 and June 6-7, 2005, the Board, including
the Independent Trustees considered the factors and reached the
conclusions described below relating to the selection of the Adviser and
the continuation of the Advisory Agreement. During such meetings, the
Board's Contracts/Operations Committee and the Independent Trustees also
met in executive sessions with their independent legal counsel. In
evaluating the Advisory Agreement, the Board, including the
Contracts/Operations Committee and the Independent Trustees, reviewed a
broad range of information requested for this purpose by the Independent
Trustees, including but not limited to the following: (i) the investment
performance of the Fund and a broader universe of relevant funds (the
"Universe") selected by Lipper Inc. ("Lipper"), an independent provider of
investment company data, for a range of periods, (ii) advisory and other
fees incurred by, and the expense ratios of, the Fund and a peer group of
comparable funds selected by Lipper (the "Peer Group"), (iii) the advisory
fees of comparable portfolios of other clients of the Adviser, (iv) the
Adviser's financial results and condition, including its and certain of
its affiliates' profitability from services performed for the Fund, (v)
breakpoints in the Fund's and the Peer Group's fees and a study undertaken
at the direction of the Independent Trustees as to the allocation of the
benefits of economies of scale between the Fund and the Adviser, (vi) the
Adviser's record of compliance with applicable laws and regulations, with
the Fund's investment policies and restrictions, and with the Fund's Code
of Ethics and the structure and responsibilities of the Adviser's
compliance department, (vii) the background and experience of senior
management and investment professionals, and (viii) the nature, cost and
character of advisory and non-investment management services provided by
the Adviser and its affiliates.

Nature, Extent and Quality
of Services

The Board considered the ability of the Adviser, based on its resources,
reputation and other attributes, to attract and retain qualified
investment professionals, including research, advisory, and supervisory
personnel. The Board further considered the compliance programs and
compliance records of the Adviser. In addition, the Board took into
account the administrative services provided to the Fund by the Adviser
and its affiliates.

Based on the above factors, together with those referenced below, the
Board concluded that, within the context of its full deliberations, the
nature, extent and quality of the investment advisory services provided to
the Fund by the Adviser were sufficient to support renewal of the Advisory
Agreement.

Fund Performance

The Board considered the performance results for the Fund over various
time periods. The Board also considered these results in comparison to the
performance of the Universe, as well as the Fund's benchmark indices.
Lipper determined the Universe


33



for the Fund. The Board reviewed with a represen tative of Lipper the
methodology used by Lipper to select the funds in the Universe and the
Peer Group.

The Board noted that the performance of the Fund was below the median and
average performance of its Universe for the time periods under review. The
Board also noted that the Fund consistently performed higher than one of
its benchmark indices, the Lehman Brothers Government/Corporate Bond
Index, for the time periods under review, but performed lower than its
other benchmark index, the Lipper Closed-End Investment Grade Funds Index,
during the more recent periods under review. The Adviser discussed with
the Board factors contributing to the Fund's performance results. The
Adviser noted that, in its view, the Fund's Universe was over-inclusive.
The Adviser provided additional analysis which demonstrated that the
Fund's performance was consistent with other similarly leveraged
closed-end funds. The Board indicated its intent to continue to monitor
the Fund's performance trends.

Investment Advisory Fee
Rates and Expenses

The Board reviewed and considered the contractual investment advisory fee
rate payable by the Fund to the Adviser for investment advisory services
(the "Advisory Agreement Rate"). The Board received and considered
information comparing the Advisory Agreement Rate with the advisory fees
for the Peer Group. The Board noted that the Advisory Agreement Rate was
lower than the median rate of the Peer Group, and reasonable in relation
to the services provided.

The Board received and considered information regarding the Fund's total
operating expense ratio and its various components, including contractual
advisory fees, actual advisory fees, non-management fees, transfer agent
fees and custodian fees, including and excluding investment-related
expenses. The Board also considered comparisons of these expenses to the
Peer Group and the Universe. The Board noted that the total operating
expense ratio of the Fund was slightly higher than the Peer Group's and
Universe's median total operating expense ratio due, in part, to the
Fund's transfer agency expense. The Board noted that, historically, the
Fund's total operating expense ratio has been consistently below the
Universe's median total operating expense ratio.

The Adviser also discussed the Lipper data and rankings, and other
relevant information, for the Fund. Based on the above-referenced
considerations and other factors, the Board concluded that the Fund's
overall expense results and performance supported the re-approval of the
Advisory Agreement.

Profitability

The Board received and considered a detailed profitability analysis of the
Adviser based on the Advisory Agreement, as well as on other relationships
between the Fund and the Adviser and its affiliates. The Board concluded
that, in light of the costs of providing investment management and other
services to the Fund, the profits and other ancillary benefits reported by
the Adviser were not unreasonable.

Economies of Scale

The Board received and considered general information regarding economies
of scale with respect to the management of the Fund, including the Fund's
ability to appropriately benefit from economies of scale under the Fund's
fee structure. The Board recognized the inherent limitations of any
analysis of economies of scale, stemming largely from the Board's
understanding that most of the Adviser's costs are not specific to
individual Funds, but rather are incurred across a variety of products and
services.

The Board observed that the Advisory Agreement offers breakpoints.
However, the Board considered the limited


34



relevance of economies of scale in the context of a closed-end fund that,
unlike an open-end fund, does not continuously offer its shares, and
concluded that the fees were fair and equitable based on relevant factors,
including the Fund's total expenses ranking relative to its Peer Group.

Information About
Services to Other Clients

The Board also received information about the nature, extent and quality
of services and fee rates offered by the Adviser to its other clients,
including other registered investment companies, institutional investors
and separate accounts. The Board concluded that the Advisory Agreement
Rate was not unreasonable, taking into account fee rates offered to others
by the Adviser and giving effect to differences in services covered by
such fee rates.

Other Benefits to
the Adviser

The Board received information regarding potential "fall-out" or ancillary
benefits received by the Adviser and its affiliates as a result of the
Adviser's relationship with the Fund. Such benefits could include, among
others, benefits directly attributable to the relationship of the Adviser
with the Fund and benefits potentially derived from an increase in the
business of the Adviser as a result of its relationship with the Fund
(such as the ability to market to shareholders other financial products
offered by the Adviser and its affiliates).

The Board also considered the effectiveness of the Adviser's and the
Fund's policies and procedures for complying with the requirements of the
federal securities laws, including those relating to best execution of
portfolio transactions and brokerage allocation.

Other Factors and
Broader Review

As discussed above, the Board reviewed detailed materials received from
the Adviser as part of the annual re-approval process under Section 15(c)
of the 1940 Act. The Board also regularly reviews and assesses the quality
of the services that the Fund receives throughout the year. In this
regard, the Board reviews reports of the Adviser at least quarterly, which
include, among other things, a detailed portfolio review, detailed fund
performance reports and compliance reports. In addition, the Board meets
with portfolio managers and senior investment officers at various times
throughout the year.

After considering the above-described factors and based on its
deliberations and its evaluation of the information described above, the
Board concluded that approval of the continuation of the Advisory
Agreement for the Fund was in the best interest of the Fund and its
shareholders. Accordingly, the Board unanimously approved the continuation
of the Advisory Agreement.
