Dear Fellow Shareholder:

While we are pleased to report positive results for Putnam Michigan Tax
Exempt Income Fund for the fiscal year ended May 31, 2003, your fund
underperformed both its benchmark and its Lipper peer group average
during the period. Details of these results can be found on page 7.

Significant declines in state and local tax revenues, accompanied by
credit rating downgrades of both municipalities and the corporate
beneficiaries of industrial development bonds, continued to plague the
municipal bond market. The market was further tested as it faced the
challenge of digesting a record level of new issuance during the period.
In the following report, your fund's management team discusses
performance and strategy in detail and provides its view of prospects
for the fiscal year that has just begun.

In bringing you this news of your fund's performance, we would also like
to take the opportunity to tell you how much we appreciate your
confidence in Putnam. We will continue to do our utmost to deliver the
best possible results for your fund.

Respectfully yours,

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

REPORT FROM FUND MANAGEMENT

FUND HIGHLIGHTS

* For the annual period ended May 31, 2003, Putnam Michigan Tax Exempt
  Income Fund's class A shares returned 8.03% at net asset value (NAV) and
  2.85% at public offering price (POP).

* Due to disappointing performance from certain industrial development
  bond holdings, the fund underperformed its benchmark, the Lehman
  Municipal Bond Index, which returned 10.36% for the same period.

* For the same reason, the fund underperformed the average for the
  Lipper Michigan Municipal Debt Funds category, which was 9.49% for the
  period.

* See the Performance Summary on page 7 for complete fund performance,
  comparative performance, and Lipper data.

* PERFORMANCE COMMENTARY

Over the annual period ended May 31, 2003, Putnam Michigan Tax Exempt
Income Fund performed solidly on an absolute basis, although it lagged
its benchmark and the average return for its Lipper peer group. One
factor that affected performance was your fund's exposure to certain
industrial development bonds (IDBs). IDBs are issued by municipalities
but backed by the credit of companies benefiting from the financing. In
this case, the backing companies were airline companies and their
continued financial struggles hurt the demand for these bonds and
detracted from fund performance. Also affecting performance were growing
concerns over the ability of tobacco companies to continue to make
payments on tobacco settlement bonds, which are explained further on
page 4. Holdings in this sector suffered, although your fund had limited
exposure. While exposure to these two sectors led to the fund's relative
underperformance, we believe its absolute returns and the tax advantages
it continues to offer should still be attractive to Michigan investors.

Fund Profile

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


* 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 fiscal second half, 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 continues 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 2003, tax-exempt municipal bonds offered investors almost the
same yield as comparable Treasury bonds. To take advantage of this
opportunity, 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
municipal bonds, and yet, potential gains on the Treasury 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 Treasury
futures contracts would be mitigated by an even greater gain on the
municipal bonds. We have seen the latter scenario begin to develop as
municipal bonds appreciated during the period.

* HOW KEY HOLDINGS AND ALLOCATIONS AFFECTED PERFORMANCE

The fund maintained its exposure to higher-yielding securities to pursue
a higher return through the income and appreciation potential we
believed they were offering. Your fund's exposure to airline-backed
industrial development bonds (IDBs) and tobacco settlement bonds was
something management examined closely during the year. Although issued
by municipalities, IDBs are backed by the credit of companies and their
prices are affected by investor perceptions of the backing company and
its industry. While the airline industry's troubles hurt performance of
airline-backed IDBs -- which in turn detracted from fund performance --
the fund's exposure to the sector was limited. The only airline-backed
holdings in the portfolio were two Wayne Charter County Michigan Special
Airport Facilities Renovation bonds backed by Northwest Airlines.
Northwest is in better financial condition than some of its competitors
and we continued to hold these bonds.

Your fund also benefited from a limited exposure to tobacco settlement
bonds. These bonds are issued by municipalities and secured by cash
payments made in satisfaction of legal judgments against the tobacco
industry. Although they are investment grade securities, these bonds
generally offer higher yields than other bonds of comparable quality
because they are subject to special risks. 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, which was of particular concern recently, the value of the bonds
could drop. We have always approached these bonds with caution, and
maintain a low exposure to the sector overall.

Footnote reads:
* As a percentage of market value as of 5/31/03. A bond rated Baa/BBB or
  higher is considered investment grade. The chart reflects Moody's and
  Standard & Poor's ratings; percentages may include unrated bonds
  considered by Putnam Management to be of comparable quality. Ratings
  will vary over time.

As a part of our efforts to more broadly diversify your fund's
portfolio, we sold $4 million of Pontiac Hospital Financing Authority
bonds issued for North Oakland Medical Center. This hospital's financial
condition had not improved to the extent we believed it would when we
first bought the bond, and we moved a portion of the proceeds from the
sale into a more promising issue by purchasing $1.65 million worth of a
30-year Macomb County Hospital Financing Authority bonds issued for
Mount Clemens General Hospital. Mount Clemens General Hospital has a
history of solid profitability and a growing market share in an
increasingly popular area of Michigan. The capital raised from these
bonds will be used to build a surgical and cancer center, as well as a
5-story parking lot. These improvements should help increase
profitability and market share for the hospital.

We also moved out of short-duration Ford Motor Company-backed IDBs and
into Dow Chemical bonds with a comparable duration, both issued by the
Michigan State Strategic Foundation. We believe the automotive
industry's outlook to be sluggish for the near term, and that Dow
Chemical is better positioned to benefit as the economic recovery
continues.

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.

(Portfolio Member), Joyce Dragone, and Jerome Jacobs.


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, we believe the ratio of muni-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 to cover 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 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 Michigan 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 Michigan 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 Michigan 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 Michigan 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 Michigan tax exempt securities.

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 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 shares 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 Michigan. 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
$2,486,000 available to the extent allowed by tax law to offset future
capital gains, if any. The amount of the carryover and the expiration
dates are:

Loss Carryover    Expiration
- --------------    ---------------------------
      $939,000    May 31, 2008
     1,547,000    May 31, 2009

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, book
amortization/ accretion 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 $45,025 to increase distributions in excess of net
investment income and a decrease to accumulated net realized losses of
$45,025. The calculation of net investment income per share in the
financial highlights table excludes these adjustments.

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

Unrealized appreciation                               $13,738,963
Unrealized depreciation                                 3,097,290
                                               ------------------
Net unrealized appreciation                            10,641,673
Undistributed tax exempt income                           289,060
Capital loss carryforward                              (2,486,051)

Cost for federal income
tax purposes                                         $178,945,615

Note 2
Management fee, administrative
services and other transactions

Compensation of Putnam Management, for management and investment
advisory services is paid quarterly based on the average net assets of
the fund. Such fee is based on the lesser of (i) the annual rate of
0.50% of the average net assets of the fund or (ii) 0.60% of the first
$500 million of average net assets, 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 $34,288 under these arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of
which $635 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
annual rate 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 $24,216 and $774 from the sale
of class A and class M shares, respectively, and received $69,438 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 $22,098
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 $44,891,469 and $43,377,671, respectively. There were no
purchases and sales of U.S. government obligations.

PUTNAM IS A LEADER IN GLOBAL MONEY MANAGEMENT

Putnam Investments traces its heritage to the early 19th century when
ship captains hired trustees to manage their money while they were away
at sea. In a landmark 1830 decision that involved one such trustee,
Massachusetts Supreme Judicial Court Justice Samuel Putnam established
The Prudent Man Rule, a legal foundation for responsible money
management. In 1937, his great-great grandson founded Putnam with The
George Putnam Fund of Boston, the first fund to offer a balanced
portfolio of stocks and bonds. Today, Putnam Investments is one of the
largest investment management firms in the world, and this balanced
approach remains the foundation of everything we do.

With over 65 years of experience, Putnam has nearly $251 billion in
assets under management, over 100 mutual funds, over 13 million
shareholder accounts, and nearly 3,000 institutional and 401(k) clients.
(Information as of 12/31/02.)

We're one of the largest mutual fund companies in the United States.

Putnam has won the DALBAR award for service twelve times in the past
thirteen years. Putnam offers products in every investment category,
including growth, value, and blend as well as international and fixed
income.

Teamwork is a cornerstone of Putnam's investment philosophy. Our funds
are managed by teams in a collaborative environment that promotes an
active exchange of information.

Putnam's disciplined investment philosophy is based on style
consistency. We aim for less volatility over the short term and strong,
consistent performance over time. Our truth in labeling approach helps
us adhere to every fund's stated objective, style, and risk positioning.

We are committed to helping financial advisors provide sound, sensible
guidance, information, and expertise to help investors reach their
financial goals.
