FROM THE TRUSTEES

[GRAPHIC OMITTED: PHOTO OF JOHN A. HILL AND GEORGE PUTNAM III]

Dear Fellow Shareholder:

We are pleased to report positive results for Putnam Ohio Tax Exempt
Income Fund for the fiscal year ended May 31, 2003. While your fund
underperformed its benchmark during the period, at net asset value it
performed in line with its Lipper fund category average. Details of
these results can be found on page 8.

As you will see in the accompanying report from the fund's management
team, an emphasis on noncallable bonds and bonds with longer maturities
was a positive contributor to performance during the period. On the
other hand, the fund's allocation to higher-yielding lower-rated issues
detracted slightly from performance results. The managers also discuss
in detail the strategies they employed during the period and offer their
views of prospects for the fiscal year that has just begun.

Meanwhile, we would like you to know how much we appreciate your
continued confidence in Putnam. No one can say for certain, of course,
how long the current market uncertainties will last, but the management
team will continue to devote its full attention to maintaining the
fund's fine long-term record.

Respectfully yours,

/S/ JOHN A. HILL                    /S/ GEORGE PUTNAM, III

REPORT FROM FUND MANAGEMENT

FUND HIGHLIGHTS

* Putnam Ohio Tax Exempt Income Fund's class A shares posted total
  returns of 9.48% at net asset value and 4.30% at public offering price
  for the fiscal year ended May 31, 2003.

* Due to the differences in portfolio quality and composition, the fund
  underperformed its benchmark, the Lehman Municipal Bond Index, which
  returned 10.36% for the 12-month period ended May 31.

* The fund's performance at net asset value was in line with the
  average return for its Lipper category, Ohio Municipal Debt Funds,
  which was 9.19%.

* See the Performance Summary on page 8 for complete fund performance,
  comparative performance, and Lipper data.

* PERFORMANCE COMMENTARY

The fund's results should be considered in the context of a generally
favorable interest-rate environment. Investments in longer-maturity and
noncallable bonds performed well. Investments in insured and high-quality
bonds also proved to be an asset, given investors' conservative leanings and
preference for relatively secure investments. The fund's lower-rated
holdings, which contribute to the portfolio's monthly income, underperformed
in the difficult economic environment. The presence of these bonds helps
explain the fund's slight underperformance relative to its benchmark, which
is comprised primarily of high-quality tax-exempt bonds from around the
nation. We believe the markets are beginning to factor in the potential for
a return of higher interest rates. Recently, we've been positioning the fund
to limit the price depreciation that typically accompanies a rising-rate
market. These defensive measures are prudent in our estimation, given the
historically low interest rates we've seen for the past few months.

Fund Profile

Putnam Ohio Tax Exempt Income Fund seeks to provide high current income
free from federal income tax and Ohio state personal income taxes, as we
believe to be consistent with the preservation of capital. It may be
suitable for Ohio investors seeking tax-free income through a
diversified portfolio of municipal bonds issued in Ohio.


* MARKET OVERVIEW

The first half of the fiscal year was generally positive for the
municipal bond market. In an environment marked by earnings
disappointments, economic weakness, and numerous allegations of
corporate malfeasance, investors sought the relative safety of
high-quality bonds. Increased demand for bonds pushed their prices
higher, and many of your fund's holdings benefited.

In the second half of the fiscal year, several factors tempered
municipal bond performance, including significant declines in tax
revenues and subsequent downgrades in municipalities' credit quality.
United Airlines, which had provided credit backing for several
municipal-bond issues, filed for bankruptcy, as had US Airways in the
months before. In late April, American Airlines narrowly avoided a
similar fate. Various segments of the electric power sector were under
duress as well. These difficulties put pressure on industrial
development bonds (IDBs), which are issued by municipalities but backed
by companies benefiting from the financing. Lastly, over $357 billion in
municipal bonds was issued in 2002 -- an all-time record. In 2003,
supply continued to swell and is on track to exceed the previous year's
record. These factors had a dampening effect on municipal bond prices.

* STRATEGY OVERVIEW

Interest-rate sensitivity is an important consideration in the
management of bond portfolios. Duration is an investment term for
measuring this interest-rate sensitivity and can be calculated from bond
coupon rates and maturities. During the summer of 2002, we began
implementing a defensive strategy (shorter duration, less sensitivity)
in anticipation of rising interest rates. When interest rates rose in
October, we returned to a more neutral duration as the outlook for
growth in the economy was less clear. However, this positioning still
limited upside potential when the market rallied in May. As the period
ended, we believed interest rates were unsustainably low and began to
shift the portfolio back toward a more defensive position.

In early calendar 2003, when tax-exempt municipal bonds offered
investors almost the same yield as comparable Treasury bonds, we
established a cross-market arbitrage position, in which we bought
intermediate-term municipal bonds and shorted 10-year Treasury futures
contracts. Our thesis was that if interest rates should rise (causing
bond prices to fall), the fund would have a loss on the bonds, and yet,
potential gains on the futures contracts would more than compensate for
the loss. On the other hand, if rates should fall (causing bond prices
to rise), a loss on the futures contracts would be mitigated by a gain
on the bonds. We have seen the latter scenario begin to develop as
municipal bonds appreciated during the second half of the period.

* HOW FUND HOLDINGS AND ALLOCATIONS AFFECTED PERFORMANCE

Although primarily an investment-grade fund, your portfolio maintained
its exposure to higher-yielding securities to pursue a higher return
through the income and appreciation potential we believed they were
offering. With so much uncertainty about economic growth and the
direction of interest rates clouding the fiscal year, we took steps to
broaden the fund's exposure across and within the various sectors that
make up the portfolio. We believe a well-diversified cross section of
holdings is one of the best strategies for reducing risk and protecting
the portfolio against negative or unforeseen events. For example, during
the fiscal period we thought that the combined weightings of Ohio Edison
and Cleveland Electric, two of the fund's electric power holdings from
the same issuer -- the Ohio State Air Quality Development Authority --
constituted too great a concentration of assets in  a single issuer.
Consequently, we sold the Cleveland Electric  position, which had the
shorter maturity of the two holdings,  and reinvested the proceeds from
the sale in two new holdings outside the electric power sector.

Two-thirds of the proceeds from this sale were invested in Ohio State
Higher Educations Facility bonds issued for Kenyon College. These
mandatory put bonds, which carry a coupon of 5.05% and mature on 7/1/37
are rated A2 and A by Moody's and Standard & Poor's, respectively. With
mandatory put bonds, the issuer will redeem the bonds at par, or face
value, at a stated time before maturity -- in this case 7/1/16. We think
the education sector is relatively stable, rarely experiences defaults
and can offer above-average yields. These put bonds are financing
improvements to an athletic facility and are backed by strong
fundamentals, including a solid endowment, strong alumni support, and
high student applications.

Most of the balance of the utility sale proceeds were invested  in
A-rated Cuyahoga County bonds issued for the Cleveland Clinic Health
System. We've seen a large supply of uninsured investment-grade hospital
bonds coming to market in recent months, improving the number and
quality of prospects for your portfolio. In addition to refinancing
older, more expensive debt at today's historically low interest rates,
hospitals in high-growth locations are requiring more resources to
finance their expansion to meet increasing patient demand. The Cleveland
Clinic, which serves northeast Ohio and southwest Florida, has a medical
and educational reputation on par with Johns Hopkins and the Mayo
Clinic. While the Clinic previously incurred investment losses, we
believe the steady, high-quality delivery of its core health services in
its target markets should eventually restore much of its diminished cash
flow.

We believe the fund's diversification also helped soften the effects of
a price decline in its investment in Cleveland Ohio Airport Authority
Revenue bonds, which are backed by Continental Airlines. The airline
industry as a whole has been caught in a headwind of negative events
that started when the terrorist attacks of September 11, 2001, sharply
reduced airline travel. The sluggish economy that followed further
reduced business travel, while high jet-fuel prices increased costs.
Finally, the war in Iraq and (most recently) concern about SARS further
hampered the industry's efforts to recover. However, the recent
labor/management negotiations that enabled American Airlines to stay in
business, at least for a time, is renewing our interest in this sector,
which seems overdue for a turnaround.

  quality. Ratings will vary over time.


Many states across the country have been driven into historically high
deficit positions over the past year. The slowing economy, along with
weakness in the stock market, higher Medicaid costs, a sharp reduction
in capital gain tax revenues and slower personal, sales and corporate
income tax collections, have contributed to this trend. This makes
general obligation (GO) bonds especially vulnerable to credit
downgrades, since they are financed by the tax revenues raised by state
and local governments. Several states have already seen their credit
downgraded by the rating agencies. While the downgrade risk for Ohio is
high, especially given the fact that it has been on a negative credit
watch since August 2002, the state's ratings by the three major rating
agencies held steady throughout the fiscal year. Credit quality remains
a critical determinant in our selection process, and we're following the
situation closely but still feel confident that the issuers of the GOs
held by the fund will meet their debt obligations.

Tobacco settlement bonds are issued by municipalities and secured by
cash payments made in satisfaction of legal judgments against the
tobacco industry. Since they are subject to special risks, they
generally offer higher yields than other bonds of comparable quality.
Among the special risks of investing in tobacco settlement bonds is the
possibility that interest payments could be affected by further
litigation against the tobacco industry. Furthermore, if the supply of
tobacco settlement bonds exceeds demand, the value of the bonds could
drop. We have always approached these bonds with caution, and feel
comfortable that the fund's two holdings, which constitute less than 1%
of total assets, are making a valuable contribution to the portfolio's
income stream and diversification. Please note that all holdings
discussed in this report are subject to review in accordance with the
fund's investment strategy and may vary in the future.

THE OUTLOOK FOR YOUR FUND

The following commentary reflects anticipated developments that could
affect your fund over the next six months, as well as your management
team's plans for responding to them.

Our current outlook for the municipal bond market is cautiously
optimistic. The conflict with Iraq is largely over, and investors are
focused on economic concerns on the home front. While serious issues
remain, the level of uncertainty in the world seems to have eased a bit,
though we expect continued volatility.

Further, we expect that market yields will move higher in the near term
as a weakening dollar, Federal Reserve Board policy, the recently
enacted tax cut package, and growing federal budget deficits take
effect.

Municipal budgets will continue to face significant pressures in the
months ahead. Governments will wrangle with how to implement costly
home-front protection measures while at the same time pushing tax cuts
to stimulate economic growth. Historically, improvement in the credit
quality of state and local governments has lagged a general economic
recovery, so we expect municipal credit quality to remain fragile for
some time to come.

Over the next few months, the ratio of municipal bond yields to
comparable Treasury yields is likely to return to more normal levels.
Accordingly, we will look for opportunities to reduce our cross-market
arbitrage position (by selling municipal bonds and buying back the
Treasury futures contracts) and we expect the fund will profit from the
transactions.

In our opinion, the market continues to offer attractive value and
compelling risk/reward characteristics. With credit spreads remaining
very generous, we believe credit risk is worth taking in moderate
amounts. We believe municipal bonds could perform well relative to other
fixed-income sectors, because demand for the bonds is firm and we expect
supply should moderate as rates move higher. We believe we have
positioned your fund to take advantage of the market's potential.

The views expressed in this report are exclusively those of Putnam
Management. They are not meant as investment advice. This fund
concentrates its investments in one state and involves more risk than a
fund that invests more broadly.

Performance assumes reinvestment of distributions and does not account
for taxes. Returns at public offering price (POP) for class A and M
shares reflect a sales charge of 4.75% and 3.25%, respectively. Class B
share returns reflect the applicable contingent deferred sales charge
(CDSC), which is 5% in the first year, declining to 1% in the sixth
year, and is eliminated thereafter. Performance for class B and M shares
before their inception is derived from the historical performance of
class A shares, adjusted for the applicable sales charge (or CDSC) and
higher operating expenses for such shares.

TERMS AND DEFINITIONS

Total return shows how the value of the fund's shares changed over time,
assuming you held the shares through the entire period and reinvested
all distributions in the fund.

Net asset value (NAV) is the price, or value, of one share of a mutual
fund, without a sales charge. NAVs fluctuate with market conditions. The
NAV is calculated by dividing the net value of all the fund's assets by
the number of outstanding shares.

Public offering price (POP) is the price of a mutual fund share plus the
maximum sales charge levied at the time of purchase. POP performance
figures shown here assume the 4.75% maximum sales charge for class A
shares and 3.25% for class M shares.

Contingent deferred sales charge (CDSC) is a charge applied at the time
of the redemption of class B shares and assumes redemption at the end of
the period. Your fund's class B CDSC declines from a 5% maximum during
the first year to 1% during the sixth year. After the sixth year, the
CDSC no longer applies.

Class A shares are generally subject to an initial sales charge and no
sales charge on redemption (except on certain redemptions of shares
bought without an initial sales charge).

Class B shares may be subject to a sales charge upon redemption.

Class M shares have a lower initial sales charge and a higher  12b-1 fee
than class A shares and no sales charge on redemption (except on certain
redemptions of shares bought without an initial sales charge).

PUTNAM'S POLICY ON CONFIDENTIALITY

In order to conduct business with our shareholders, we must obtain
certain personal information such as account holders' addresses,
telephone numbers, Social Security numbers, and the names of their
financial advisors. We use this information to assign an account
number and to help us maintain accurate records of transactions and
account balances.

It is our policy to protect the confidentiality of your information,
whether or not you currently own shares of our funds, and in particular,
not to sell information about you or your accounts to outside marketing
firms. We have safeguards in place designed to prevent unauthorized
access to our computer systems and procedures to protect personal
information from unauthorized use.

Under certain circumstances, we share this information with outside
vendors who provide services to us, such as mailing and proxy
solicitation. In those cases, the service providers enter into
confidentiality agreements with us, and we provide only the information
necessary to process transactions and perform other services related to
your account. We may also share this information with our Putnam
affiliates to service your account or provide you with information about
other Putnam products or services. It is also our policy to share
account information with your financial advisor, if you've listed one on
your Putnam account.

If you would like clarification about our confidentiality policies or
have any questions or concerns, please don't hesitate to contact us at
1-800-225-1581, Monday through Friday, 8:30 a.m. to 7:00 p.m., or
Saturdays from 9:00 a.m. to 5:00 p.m. Eastern Time.


A GUIDE TO THE FINANCIAL STATEMENTS

These sections of the report, as well as the accompanying Notes,
preceded by the Report of independent accountants, constitute the fund's
financial statements.

The fund's portfolio  lists all the fund's investments and their values
as of the last day of the reporting period. Holdings are organized by
asset type and industry sector, country, or state to show areas of
concentration and diversification.

Statement of assets and liabilities  shows how the fund's net assets
and share price are determined. All investment and noninvestment
assets are added together.  Any unpaid expenses and other
liabilities are subtracted from this total. The result is divided by
the number of shares to determine the net asset value per share,
which is calculated separately for each class of shares. (For funds
with preferred shares, the amount subtracted from total assets
includes the net assets allocated to remarketed preferred shares.)

Statement of operations  shows the fund's net investment gain or loss.
This is done by first adding up all the fund's earnings -- from
dividends and interest income -- and subtracting its operating expenses
to determine net investment income (or loss).  Then, any net gain or
loss the fund realized on the sales of its holdings -- as well as any
unrealized gains or losses over the period -- is added to or subtracted
from the net investment result to determine the fund's net gain or loss
for the fiscal year.

Statement of changes in net assets  shows how the fund's net assets were
affected by distributions to shareholders and by changes in the number
of the fund's shares. It lists distributions and their sources (net
investment income or realized capital gains) over the current reporting
period and the most recent fiscal year-end. The distributions listed
here may not match the sources listed in the Statement of operations
because the distributions are determined on a tax basis and may be paid
in a different period from the one in which they were earned.

Financial highlights  provide an overview of the fund's investment
results,  per-share distributions, expense ratios, net investment income
ratios, and portfolio turnover in one summary table, reflecting the five
most recent reporting periods. In a semiannual report, the highlight
table also includes the current reporting period. For open-end funds, a
separate table is provided for each share class.


REPORT OF INDEPENDENT ACCOUNTANTS

To the Trustees and Shareholders of
Putnam Ohio Tax Exempt Income Fund

In our opinion, the accompanying statement of assets and liabilities,
including the fund's portfolio (except for bond ratings) and the related
statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial
position of Putnam Ohio Tax Exempt Income Fund (the "fund") at May 31,
2003, and the results of its operations, the changes in its net assets
and the financial highlights for the periods indicated, in conformity
with accounting principles generally accepted in the United States of
America. These financial statements and financial highlights (hereafter
referred to as "financial statements") are the responsibility of the
fund's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of
these financial statements in accordance with auditing standards
generally accepted in the United States of America, which require that
we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the
amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe
that our audits, which included confirmation of investments owned at May
31, 2003, by correspondence with the custodian, provide a reasonable
basis for our opinion.

NOTES TO FINANCIAL STATEMENTS
May 31, 2003

Note 1
Significant accounting policies

Putnam Ohio Tax Exempt Income Fund (the "fund") is registered under the
Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company. The fund seeks as high a level of current
income exempt from federal income tax and Ohio personal income tax as
Putnam Investment Management, LLC ("Putnam Management"), the fund's
manager, an indirect wholly-owned subsidiary of Putnam, LLC, believes is
consistent with preservation of capital by investing primarily in a
portfolio of investment-grade Ohio tax-exempt securities with
intermediate- to long-term maturities.

The fund offers class A, class B and class M shares. Class A shares are
sold with a maximum front-end sales charge of 4.75%. Class B shares,
which convert to class A shares after approximately eight years, do not
pay a front-end sales charge, but pay a higher ongoing distribution fee
than class A and class M shares, and are subject to a contingent
deferred sales charge, if those shares are redeemed within six years of
purchase. Class M shares are sold with a maximum front-end sales charge
of 3.25% and pay an ongoing distribution fee that is higher than class A
but lower than class B shares.

Expenses of the fund are borne pro-rata by the holders of each class of
shares, except that each class bears expenses unique to that class
(including the distribution fees applicable to such class). Each class
votes as a class only with respect to its own distribution plan or other
matters on which a class vote is required by law or determined by the
Trustees. Shares of each class would receive their pro-rata share of the
net assets of the fund, if the fund were liquidated. In addition, the
Trustees declare separate dividends on each class of shares.

The following is a summary of significant accounting policies
consistently followed by the fund in the preparation of its financial
statements. The fund may be affected by economic and political
developments in the state of Ohio. The preparation of financial
statements is in conformity with accounting principles generally
accepted in the United States of America and requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities in the financial statements and the reported amounts of
increases and decreases in net assets from operations during the
reporting period. Actual results could differ from those estimates.

A) Security valuation Tax-exempt bonds and notes are valued on the basis
of valuations provided by an independent pricing service, approved by
the Trustees. Such services use information with respect to transactions
in bonds, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities in
determining value. Restricted securities are valued at fair value
following procedures approved by the Trustees. Such valuations and
procedures are reviewed periodically by the Trustees.

B) Security transactions and related investment income Security
transactions are recorded on the trade date (date the order to buy or
sell is executed). Gains or losses on securities sold are determined on
the identified cost basis.

Interest income is recorded on the accrual basis. All premiums/discounts
are amortized/accreted on a yield-to-maturity basis. The premium in
excess of the call price, if any, is amortized to the call date;
thereafter, any remaining premium is amortized to maturity.

C) Futures and options contracts The fund may use futures and options
contracts to hedge against changes in the values of securities the fund
owns or expects to purchase. The fund may also write options on
securities it owns or in which it may invest to increase its current
returns.

The potential risk to the fund is that the change in value of futures
and options contracts may not correspond to the change in value of the
hedged instruments. In addition, losses may arise from changes in the
value of the underlying instruments, if there is an illiquid secondary
market for the contracts, or if the counterparty to the contract is
unable to perform. When the contract is closed, the fund records a
realized gain or loss equal to the difference between the value of the
contract at the time it was opened and the value at the time it was
closed. Realized gains and losses on purchased options are included in
realized gains and losses on investment securities.

Futures contracts are valued at the quoted daily settlement prices
established by the exchange on which they trade. The fund and the broker
agree to exchange an amount of cash equal to the daily fluctuation in
the value of the futures contract. Such receipts or payments are known
as "variation margin." Exchange traded options are valued at the last
sale price, or if no sales are reported, the last bid price for
purchased options and the last ask price for written options. Options
traded over-the-counter are valued using prices supplied by dealers.
Futures and written option contracts outstanding at period end are
listed after The fund's portfolio.

D) Line of credit The fund has entered into a committed line of credit
with certain banks. This line of credit agreement includes restrictions
that the fund maintain an asset coverage ratio of at least 300% and that
borrowings not exceed prospectus limitations. For the year ended May 31,
2003, the fund had no borrowings against the line of credit.

E) Federal taxes It is the policy of the fund to distribute all of its
income within the prescribed time and otherwise comply with the
provisions of the Internal Revenue Code applicable to regulated
investment companies. It is also the intention of the fund to distribute
an amount sufficient to avoid imposition of any excise tax under Section
4982 of the Internal Revenue Code of 1986, as amended. Therefore, no
provision has been made for federal taxes on income, capital gains or
unrealized appreciation on securities held nor for excise tax on income
and capital gains.

At May 31, 2003, the fund had a capital loss carryover of approximately
$4,308,000 available to the extent allowed by tax law to offset future
net capital gains, if any. The amount of the carryover and the
expiration dates are:

Loss Carryover    Expiration
- --------------    ------------------
    $3,948,000    May 31, 2009
       360,000    May 31, 2010

F) Distributions to shareholders Income dividends are recorded daily by
the fund and are paid monthly. Distributions from capital gains, if any,
are recorded on the ex-dividend date and paid at least annually. The
amount and character of income and gains to be distributed are
determined in accordance with income tax regulations which may differ
from generally accepted accounting principles. These differences include
temporary and permanent differences of dividends payable, realized and
unrealized gains and losses on certain futures contracts, market
discount and straddle loss deferrals. Reclassifications are made to the
fund's capital accounts to reflect income and gains available for
distribution (or available capital loss carryovers) under income tax
regulations. For the year ended May 31, 2003, the fund reclassified
$164,890 to decrease distributions in excess of net investment income,
with an increase to accumulated net realized losses of $164,890.

The tax basis components of distributable earnings and the federal tax
cost as of period end were as follows:

Unrealized appreciation                   $20,187,881
Unrealized depreciation                    (1,527,314)
                                        -------------
Net unrealized appreciation                18,660,567
Undistributed tax-exempt income               326,689
Undistributed ordinary income                 145,833
Capital loss carryforward                  (4,308,173)
Post-October loss                                  --

Cost for federal income
tax purposes                             $209,153,137

Note 2
Management fee, administrative
services and other transactions

Putnam Management is paid for management and investment advisory
services quarterly based on the average net assets of the fund. Such fee
is based on the lesser of (i) an annual rate of 0.50% of the average net
assets of the fund or (ii) the following annual rates expressed as a
percentage of the fund's average net assets: 0.60% of the first $500
million, 0.50% of the next $500 million, 0.45% of the next $500 million,
0.40% of the next $5 billion, 0.375% of the next $5 billion, 0.355% of
the next $5 billion, 0.34% of the next $5 billion and 0.33% thereafter.

The fund reimburses Putnam Management an allocated amount for the
compensation and related expenses of certain officers of the fund and
their staff who provide administrative services to the fund. The
aggregate amount of all such reimbursements is determined annually by
the Trustees.

Custodial functions for the fund's assets are provided by Putnam
Fiduciary Trust Company (PFTC), a subsidiary of Putnam, LLC. Investor
servicing agent functions are provided by Putnam Investor Services, a
division of PFTC.

The fund has entered into an arrangement with PFTC whereby credits
realized as a result of uninvested cash balances are used to reduce a
portion of the fund's expenses. For the year ended May 31, 2003, the
fund's expenses were reduced by $41,082 under these arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of
which $646 has been allocated to the fund, and an additional fee for
each Trustees meeting attended. Trustees receive additional fees for
attendance at certain committee meetings.

The fund has adopted a Trustee Fee Deferral Plan (the "Deferral Plan")
which allows the Trustees to defer the receipt of all or a portion of
Trustees fees payable on or after July 1, 1995. The deferred fees remain
invested in certain Putnam funds until distribution in accordance with
the Deferral Plan.

The fund has adopted an unfunded noncontributory defined benefit pension
plan (the "Pension Plan") covering all Trustees of the fund who have
served as a Trustee for at least five years. Benefits under the Pension
Plan are equal to 50% of the Trustee's average total retainer and
meeting fees for the three years preceding retirement. Pension expense
for the fund is included in Compensation of Trustees in the Statement of
operations. Accrued pension liability is included in Payable for
compensation of Trustees in the Statement of assets and liabilities.

The fund has adopted distribution plans (the "Plans") with respect to
its class A, class B and class M shares pursuant to rule 12b-1 under the
Investment Company Act of 1940. The purpose of the Plans is to
compensate Putnam Retail Management, a wholly-owned subsidiary of
Putnam, LLC and Putnam Retail Management GP, Inc., for services provided
and expenses incurred by it in distributing shares of the fund. The
Plans provide for payments by the fund to Putnam Retail Management at an
annual rate of up to 0.35%, 1.00% and 1.00% of the average net assets
attributable to class A, class B and class M shares, respectively. The
Trustees have approved payment by the fund at the annual rates of 0.20%,
0.85% and 0.50% of the average net assets attributable to class A, class
B and class M shares, respectively.

For the year ended May 31, 2003, Putnam Retail Management, acting as
underwriter, received net commissions of $27,400 and $605 from the sale
of class A and class M shares, respectively, and received $56,101 in
contingent deferred sales charges from redemptions of class B shares. A
deferred sales charge of up to 1.00% is assessed on certain redemptions
of class A shares that were purchased without an initial sales charge as
part of an investment of $1 million or more. For the year ended May 31,
2003, Putnam Retail Management, acting as underwriter, received $40 on
class A redemptions.

Note 3
Purchases and sales of securities

During the year ended May 31, 2003, cost of purchases and proceeds from
sales of investment securities other than short-term investments
aggregated $57,253,911 and $52,006,706, respectively. There were no

HELP YOUR INVESTMENT GROW

Set up a program for systematic investing with as little as $25 a month
from a Putnam fund or from your own savings or checking account.
(Regular investing does not guarantee a profit or protect against loss
in  a declining market.)

SWITCH FUNDS EASILY

You can move money from one Putnam fund to another within the same class
of shares without a service charge. (This privilege is subject to change
or termination.)

ACCESS YOUR MONEY EASILY

You can have checks sent regularly or redeem shares any business day at
the then-current net asset value, which may be more or less than the
original cost of the shares. Class B and class C shares carry a sales
charge that is applied to certain withdrawals.

HOW TO BUY ADDITIONAL SHARES

You may buy shares through your financial advisor or directly from
Putnam. To open an account by mail, send a check made payable to the
name of the fund along with a completed fund application. To add to an
existing account, complete the investment slip found at the top of your
Confirmation of Activity statement and return it with a check payable to
your fund.
