Prospectus Supplement 213760 4/04 dated April 14, 2004 to:

PUTNAM RESEARCH FUND
Prospectuses dated November 30, 2003

As previously disclosed in a press release dated March 2, 2004, Putnam Management discovered that in early 2001, certain Putnam employees had willfully circumvented controls in connection with the correction of operational errors with respect to a 401(k) client's investment in certain Putnam Funds, which led to losses in the fund. Putnam made restitution of approximately $1.8 million to the fund on February 19, 2004, representing approximately $0.014 per share outstanding as of such date. Had this payment been made when the error occurred, it would have had the effect of increasing the net asset value of each class of the fund's shares by $0.01 to $0.02 per share. Putnam and the fund's Trustees are in the process of finalizing the restitution amounts. Additional amounts may be warranted. Putnam has also implemented a number of personnel changes, including senior personnel, and has begun to implement changes in procedures to address these items. Putnam has informed the SEC, the fund's Trustees and independent auditors.

The following is added as a new second paragraph under the heading "Performance Information:"

Performance information shown in the bar chart and table has been adjusted to reflect the restitution payment from Putnam Management as if it had been made on January 5, 2001. This payment had the effect of increasing the net asset value of each class of the fund's shares for each day during the period by $0.01 to $0.02 per share. If the adjustment had not been so reflected, performance shown for periods ending December 31, 2003 and for calendar years 2001, 2002 and 2003 would have been lower.

The following information replaces the bar chart and table appearing under the caption "Performance Information":

[GRAPHIC OMITTED: CALENDAR YEAR TOTAL RETURNS]

CALENDAR YEAR TOTAL RETURNS

1996                 23.26%
1997                 32.92%
1998                 29.45%
1999                 27.57%

2002                -22.21%
2003                 25.17%

Performance figures in the bar chart do not reflect the impact of sales charges. If they did, performance would be less than that shown. Year-to-date performance through 3/31/04 was 1.08%. During the periods shown in the bar chart, the highest return for a quarter was 23.77% (quarter ending 12/31/98) and the lowest return for a quarter was -20.18% (quarter ending 9/30/01).

-------------------------------------------------------------------------------

Unlike the bar chart, this performance information reflects the impact of sales charges. Class A and class M share performance reflects the current maximum initial sales charges (which for class A shares reflects a reduction that took effect after December 31, 2003); class B and class C share performance reflects the maximum applicable deferred sales charge if shares had been redeemed on 12/31/03 and, for class B shares, does not assume conversion to class A shares after eight years. For periods before the inception of class B shares (6/15/98), class C shares (2/1/99), class M shares (6/15/98) and class R shares (1/21/03), performance shown for these classes in the table is based on the performance of the fund's class A shares, adjusted to reflect the appropriate sales charge and the higher 12b-1 fees paid by the class B, class C, class M and class R shares. The fund's performance through 7/31/98 benefited from Putnam Management's agreement to limit the fund's expenses. The fund's performance is compared to the S&P 500 Index, an unmanaged index of common stocks frequently used as a general measure of U.S. stock performance. After-tax returns reflect the highest individual federal income tax rates and do not reflect state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are shown for class A shares only and will vary for other classes. After-tax returns are not relevant to those investing through 401(k) plans, IRAs or other tax-deferred arrangements.

The following information replaces the first paragraph appearing under the caption "Financial Highlights":

The financial highlights tables are intended to help you understand the fund's recent financial performance. Certain information reflects financial results for a single fund share. The total returns represent the rate that an investor would have earned or lost on an investment in the fund, assuming reinvestment of all dividends and distributions. Except for the unaudited information for the six months ended January 31, 2004, this information has been derived from the fund's financial statements, which have been audited by KPMG LLP. Its report and the fund's financial statements are included in the fund's annual report to shareholders, which is available upon request.

To comply with regulatory requirements, the following unaudited information for the six months ended January 31, 2004 supplements the information contained in the Financial Highlights table:

A guide to the financial statements

These sections of the report, as well as the accompanying Notes, 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 period.

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.

Note 1
Significant accounting policies

Putnam Research Fund (the "fund") is a series of Putnam Investment Funds (the "trust"), which is registered under the Investment Company Act of 1940, as amended, as a diversified, open-end management investment company. The objective of the fund is to seek capital appreciation by investing primarily in common stocks.

The fund offers class A, class B, class C, class M, class R and class Y shares. Class A shares are sold with a maximum front-end sales charge of 5.25%. Prior to January 28, 2004, the maximum front-end sales charge for class A shares was 5.75%. 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, class M and class R shares, and are subject to a contingent deferred sales charge, if those shares are redeemed within six years of purchase. Class C shares are subject to the same fees and expenses as class B shares, except that class C shares have a one-year 1.00% contingent deferred sales charge and do not convert to class A shares. Class M shares are sold with a maximum front-end sales charge of 3.50% and pay an ongoing distribution fee that is higher than class A and class R shares but lower than class B and class C shares. Class R shares are sold without a front-end sales charge and pay an ongoing distribution fee that is higher than class A shares, but lower than class B, class C and class M shares. Class R shares are offered to qualified employee-benefit plans. Class Y shares, which are sold at net asset value, are generally subject to the same expenses as class A, class B, class C, class M and class R shares, but do not bear a distribution fee. Class Y shares are sold to certain eligible purchasers including certain defined contribution plans (including corporate IRAs), bank trust departments and trust companies.

Effective April 19, 2004, a 2.00% redemption fee may apply to any shares that are redeemed (either by selling or exchanging into another fund) within 5 days of purchase.

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 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 Investments for which market quotations are readily available are valued at the last reported sales price on their principal exchange, or official closing price for certain markets. If no sales are reported -- as in the case of some securities traded over-the-counter -- a security is valued at its last reported bid price. Many securities markets and exchanges outside the U.S. close prior to the close of the New York Stock Exchange and, therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the New York Stock Exchange. Accordingly, on certain days, the fund will fair value foreign securities taking into account multiple factors, including movements in the U.S. securities markets. The number of days on which fair value prices will be used will depend on market activity and it is possible that fair value prices will be used by the fund to a significant extent. Securities quoted in foreign currencies are translated into U.S. dollars at the current exchange rate. Short-term investments having remaining maturities of 60 days or less are valued at amortized cost, which approximates fair value. Other investments, including restricted securities, are valued at fair value following procedures approved by the Trustees. Such valuations and procedures are reviewed periodically by the Trustees.

B) Joint trading account The fund may transfer uninvested cash balances, including cash collateral received under security lending arrangements, into a joint trading account along with the cash of other registered investment companies and certain other accounts managed by Putnam Investment Management, LLC ("Putnam Management"), the fund's manager, an indirect wholly-owned subsidiary of Putnam, LLC. These balances may be invested in issuers of high-grade short-term investments having maturities of up to 397 days for collateral received under security lending arrangements and up to 90 days for other cash investments.

C) 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. Dividend income is recognized on the ex-dividend date except that certain dividends from foreign securities are recognized as soon as the fund is informed of the ex-dividend date. Non-cash dividends, if any, are recorded at the fair market value of the securities received.

D) Foreign currency translation The accounting records of the fund are maintained in U.S. dollars. The market value of foreign securities, currency holdings, and other assets and liabilities are recorded in the books and records of the fund after translation to U.S. dollars based on the exchange rates on that day. The cost of each security is determined using historical exchange rates. Income and withholding taxes are translated at prevailing exchange rates when earned or incurred. The fund does not isolate that portion of realized or unrealized gains or losses resulting from changes in the foreign exchange rate on investments from fluctuations arising from changes in the market prices of the securities. Such gains and losses are included with the net realized and unrealized gain or loss on investments. Net realized gains and losses on foreign currency transactions represent net realized exchange gains or losses on closed forward currency contracts, disposition of foreign currencies, currency gains and losses realized between the trade and settlement dates on securities transactions and the difference between the amount of investment income and foreign withholding taxes recorded on the fund's books and the U.S. dollar equivalent amounts actually received or paid. Net unrealized appreciation and depreciation of assets and liabilities in foreign currencies arise from changes in the value of open forward currency contracts and assets and liabilities other than investments at the period end, resulting from changes in the exchange rate. Investments in foreign securities involve certain risks, including those related to economic instability, unfavorable political developments, and currency fluctuations, not present with domestic investments.

E) Forward currency contracts The fund may buy and sell forward currency contracts, which are agreements between two parties to buy and sell currencies at a set price on a future date. These contracts are used to protect against a decline in value relative to the U.S. dollar of the currencies in which its portfolio securities are denominated or quoted (or an increase in the value of a currency in which securities a fund intends to buy are denominated, when a fund holds cash reserves and short term investments). The U.S. dollar value of forward currency contracts is determined using current forward currency exchange rates supplied by a quotation service. The market value of the contract will fluctuate with changes in currency exchange rates. The contract is marked to market daily and the change in market value is recorded as an unrealized gain or loss. 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. The fund could be exposed to risk if the value of the currency changes unfavorably, if the counterparties to the contracts are unable to meet the terms of their contracts or if the fund is unable to enter into a closing position. Forward currency contracts outstanding at period end, if any, are listed after the fund's portfolio.

F) 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, if any, are listed after the fund's portfolio.

G) Security lending The fund may lend securities, through its agents, to qualified borrowers in order to earn additional income. The loans are collateralized by cash and/or securities in an amount at least equal to the market value of the securities loaned. The market value of securities loaned is determined daily and any additional required collateral is allocated to the fund on the next business day. The risk of borrower default will be borne by the fund's agents; the fund will bear the risk of loss with respect to the investment of the cash collateral. Income from securities lending is included in investment income on the Statement of operations. At January 31, 2004, the value of securities loaned amounted to $3,851,398. The fund received cash collateral of $4,151,645, which is pooled with collateral of other Putnam funds into 9 issuers of high-grade short-term investments.

H) Line of credit During the period, the fund was entered into a committed line of credit with certain banks. The line of credit agreement included restrictions that the fund would maintain an asset coverage ratio of at least 300% and that borrowings would not exceed prospectus limitations. For the period ended August 6, 2003, the fund had no borrowings against the line of credit. Effective August 6, 2003, the fund no longer participated in a committed line of credit.

I) Federal taxes It is the policy of the fund to distribute all of its taxable 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 July 31, 2003, the fund had a capital loss carryover of $739,829,523 available to the extent allowed by tax law to offset future net capital gain, if any. The amount of the carryover and the expiration dates are:

Loss Carryover       Expiration
-------------------------------
  $450,679,075    July 31, 2010
   289,150,448    July 31, 2011

Pursuant to federal income tax regulations applicable to regulated investment companies, the fund has elected to defer to its fiscal year ending July 31, 2003 $162,386,670 of losses recognized during the period November 1, 2002 to July 31, 2003.

The aggregate identified cost on a tax basis is $1,568,357,943, resulting in gross unrealized appreciation and depreciation of $145,888,360 and $22,702,428, respectively, or net unrealized appreciation of $123,185,932.

J) Distributions to shareholders Distributions to shareholders from net investment income are recorded by the fund on the ex-dividend date. 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. 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.

K) Expenses of the trust Expenses directly charged or attributable to any fund will be paid from the assets of that fund. Generally, expenses of the trust will be allocated among and charged to the assets of each fund on a basis that the Trustees deem fair and equitable, which may be based on the relative assets of each fund or the nature of the services performed and relative applicability to each fund.

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 following annual rates: 0.65% of the first $500 million of average net assets, 0.55% of the next $500 million, 0.50% of the next $500 million, 0.45% of the next $5 billion, 0.425% of the next $5 billion, 0.405% of the next $5 billion, 0.39% of the next $5 billion and 0.38% thereafter.

Effective January 28, 2004, Putnam Management has agreed to limit its compensation (and, to the extent necessary, bear other expenses) through December 31, 2004 to the extent that the fund's net expenses as a percentage of average net assets exceed the average expense ratio for the fund's Lipper peer group of front-end load funds.

The base management fee is subject to a performance adjustment based on the investment performance of the fund compared to changes in the value of the Standard & Poor's 500 ("S&P 500") composite Stock Price Index. Performance will be calculated for these purposes at the beginning of each fiscal quarter, for the thirty-six month period immediately preceding such quarter or the life of the fund, if shorter. The applicable base fee will be increased or decreased for each calendar quarter by an incentive payment or penalty at the annual rate of 0.01% of the fund's average net assets for each 1.00% increment by which the fund outperforms or underperforms the S&P 500 in excess of 3.00%, subject to a maximum increase or decrease of 0.07% of average net assets. For the period ended January 31, 2004 the base management fee represented an effective annual basic rate of 0.55% of the fund's average net assets before a decrease of $204,418 (0.02% annualized) based on performance.

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. Putnam Investor Services, a division of PFTC, provides investor servicing agent functions to the fund. During the six months ended January 31, 2004, the fund paid PFTC $2,036,602 for these services.

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. The fund also reduced expenses through brokerage service arrangements. For the six months ended, January 31, 2004, the fund's expenses were reduced by $430,300 under these arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of which $2,292 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 Trustee compensation and expenses in the Statement of operations. Accrued pension liability is included in Payable for Trustee compensation and expenses in the Statement of assets and liabilities.

The fund has adopted distribution plans (the "Plans") with respect to its class A, class B, class C, class M and class R 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 up to 0.35%, 1.00%, 1.00%, 1.00% and 1.00% of the average net assets attributable to class A, class B, class C, class M and class R shares, respectively. The Trustees have approved payment by the fund at an annual rate of 0.25%, 1.00%, 1.00%, 0.75% and 0.50% of the average net assets attributable to class A, class B, class C, class M and class R shares, respectively.

For the six months ended January 31, 2004, Putnam Retail Management, acting as underwriter, received net commissions of $67,159 and $2,301 from the sale of class A and class M shares, respectively, and received $1,058,581 and $4,236 in contingent deferred sales charges from redemptions of class B and class C shares, respectively. A deferred sales charge of up to 1.00% and 0.65% is assessed on certain redemptions of class A and class M shares, respectively. For the six months ended January 31, 2004, Putnam Retail Management, acting as underwriter, received $1,303 and no monies on class A and class M redemptions, respectively.

Note 3
Purchases and sales of securities

During the six months ended January 31, 2004, cost of purchases and proceeds from sales of investment securities other than short-term investments aggregated $968,358,057 and $1,187,787,354, respectively. There were no purchases and sales of U.S. government securities.

Note 5
Regulatory matters and litigation

On November 13, 2003, Putnam Management agreed to entry of an order by the Securities and Exchange Commission in partial resolution of administrative and cease-and-desist proceedings initiated by the SEC on October 28, 2003 in connection with alleged excessive short-term trading by at least six Putnam Management investment professionals. The SEC's findings reflect that four of those employees engaged in such trading in funds over which they had investment decision-making responsibility and had access to non-public information regarding, among other things, current portfolio holdings and valuations. The six individuals are no longer employed by Putnam Management. Under the order, Putnam Management will make restitution for losses attributable to excessive short-term trading by Putnam employees, institute new employee trading restrictions and enhanced employee trading compliance, retain an independent compliance consultant, and take other remedial actions. Putnam Management neither admitted nor denied the order's findings, which included findings that Putnam Management willfully violated provisions of the federal securities laws. A civil monetary penalty and other monetary relief, if any, will be determined at a later date. If a hearing is necessary to determine the amounts of such penalty or other relief, Putnam Management will be precluded from arguing that it did not violate the federal securities laws in the manner described in the SEC order, the findings set forth in the SEC order will be accepted as true by the hearing officer and additional evidence may be presented. Putnam Management, and not the investors in any Putnam fund, will bear all costs, including restitution, civil penalties and associated legal fees. Administrative proceedings instituted by the Commonwealth of Massachusetts on October 28, 2003 against Putnam Management in connection with alleged market-timing activities by Putnam employees and by participants in some Putnam-administered 401(k) plans are pending. Putnam Management has committed to make complete restitution for any losses suffered by Putnam shareholders as a result of any improper market-timing activities by Putnam employees or within Putnam-administered 401(k) plans.

The SEC's and Commonwealth's allegations and related matters also serve as the general basis for numerous lawsuits, including purported class action lawsuits filed against Putnam Management and certain related parties, including certain Putnam funds. Putnam Management has agreed to bear any costs incurred by Putnam funds in connection with these lawsuits. Based on currently available information, Putnam Management believes that the likelihood that the pending private lawsuits and purported class action lawsuits will have a material adverse financial impact on the fund is remote, and the pending actions are not likely to materially affect its ability to provide investment management services to its clients, including the Putnam funds.

For the period ended January 31, 2004, Putnam Management has assumed $39,557 for legal, shareholder servicing and communication, audit, and Trustee fees incurred by the fund in connection with these matters.

Review of these matters by counsel for Putnam Management and by separate independent counsel for the Putnam funds and their independent Trustees is continuing. In addition, Marsh & McLennan Companies, Inc., Putnam Management's parent company, has engaged counsel to conduct a separate review of Putnam Management's policies and controls related to short-term trading. The fund may experience increased redemptions as a result of these matters, which could result in increased transaction costs and operating expenses.

Note 6
Other matters

In connection with an ongoing review of compliance procedures and controls, Putnam Management discovered that in early January 2001, certain Putnam employees had willfully circumvented controls in connection with the correction of operational errors with respect to a 401(k) client's investment in certain Putnam Funds, which led to losses in the fund. On February 19, 2004, the fund recorded a receivable for restitution from Putnam of approximately $1.8 million as of January 31, 2004, representing approximately $.014 per share outstanding as of such date. The fund's Paid-in-Capital account reflects a corresponding increase. Had this payment been made when the error occurred, it would have had the effect of increasing the net asset value of each class of the fund's shares for each day during the period by $0.01 to $0.02 per share. Putnam and the fund's trustees are in the process of finalizing the restitution amount. Additional amounts may be warranted. Putnam has also made a number of personnel changes, including senior managers, and has begun to implement changes in procedures. Putnam has informed the SEC, the Funds' Trustees and independent auditors. The restitution made by Putnam is not reflected in the audited information appearing in the fund's financial highlights table and statement of changes in net assets.

Re: Letter of Indemnity

Ladies and Gentlemen:

Reference is made to the administrative proceedings (the "Administrative Proceedings") commenced on October 28, 2003 against Putnam Investment Management LLC ("Putnam") by the Securities and Exchange Commission and by the Massachusetts Securities Division alleging various matters related to market timing or other improper trading activity in Putnam Fund shares. Putnam serves as investment manager for each of the Putnam Funds (the "Funds") pursuant to Management Contracts which are subject to termination by the Funds on 60 days notice. Putnam is an indirect wholly-owned subsidiary of Putnam Investments LLC, which is in turn an indirect majority-owned subsidiary of March & McLennan Companies Inc.

Whereas the independent trustees of the Funds have undertaken various investigations of the matters alleged in the Administrative Proceedings; and

Whereas these matters and related matters (such as the fair valuation of portfolio holdings, the disclosure of portfolio holdings and prospectus disclosures related to the foregoing) may be the basis of further regulatory actions involving or potentially affecting the Funds or Putnam;

Whereas these matters and related matters are the basis in whole or in part for numerous private actions brought by shareholders of the Funds, in many cases as purported class actions or derivative actions, variously against the Funds, their Trustees and officers, Putnam and certain other parties (the "Private Litigation"); and

Whereas these matters and related matters may be the basis for further private actions against the Funds, their Trustees and officers;

In consideration of the continuation of the current Management Contract and other contractual and financial arrangements between each Fund and Putnam and its affiliates, Putnam hereby agrees to indemnify and hold harmless each of the Funds against any and all loss, damage, liability and expense, including reasonable fees and expenses of counsel, arising out of the matters alleged in the Administrative Proceedings, the Private Litigation or any proceedings or actions that may be threatened or commenced in the future by any person (including any regulatory authority) arising out of matters reasonably related to the foregoing matters, including without limitation:

(i) all legal and other expenses incurred by the Funds in connection with investigations undertaken by the independent Trustees;

(ii) all legal and other expenses incurred by the Funds in connection with any such proceedings or actions, including without limitation expenses related to the defense of any such proceedings or actions, compliance with disclosure requirements related to the foregoing and any special communications to Fund shareholders;

(iii) all liabilities and expenses incurred by the Funds in connection with any judgment resulting from, or settlement of, any such proceedings or actions; and

(iv) all liabilities and expenses incurred by the Funds under the provisions of the Agreement and Declaration of Trust of any Fund providing for indemnification of trustees and officers.

The Funds will use their best efforts to notify Putnam of any proceedings or actions commenced against them or against their Trustees or officers, but the failure to provide such notification shall not relieve Putnam of any liability or obligation hereunder. The Funds shall be entitled to defend any such proceedings or action against them using counsel of their choosing. Putnam shall be entitled, at its expense, to participate in the defense of any such proceedings or actions against the Funds and shall be entitled to defend any such proceedings or actions against Putnam, in each case using counsel of their choosing. The Funds will not enter into any settlement of any such proceeding or action without the consent of Putnam which consent shall not be unreasonably withheld.

In the event that the foregoing indemnification shall be unavailable to any Fund, then Putnam hereby agrees to contribute to the amount paid or payable by a Fund as a result of any loss, damage, liability or expense in such proportion as is appropriate to reflect the relative fault of Putnam and such Fund with respect to the matters which resulted in such loss, damage, liability or expense, as well as any other relevant equitable considerations.

To the extent Putnam or MMC makes a payment under this indemnity agreement, Putnam or MMC may seek reimbursement for such payment under any applicable policies of insurance.

The foregoing undertakings by Putnam shall survive the termination of any of the aforesaid Management Contracts.

Please acknowledge your receipt and acceptance of the foregoing by signing the enclosed copy of this letter in the space provided below.

Very truly yours,

Putnam Investment Management LLC
