The IRS uses the numbers for identification purposes and may also provide this information to various government agencies for tax enforcement of litigation purposes. Payers must be given the numbers whether or not recipients are required to file tax returns. Payers must generally withhold 28% of taxable interest, dividends, and certain other payments to a payee who does not furnish a taxpayer identification number to a payer. Certain penalties may also apply.

Penalties

INSTRUCTIONS
FORMING PART OF THE TERMS AND CONDITIONS OF OUR OFFER

1. Guarantee Of Signatures. Depending on how the certificates for your shares are registered and to whom you want payments or deliveries made, you may need to have the signatures on this letter of transmittal guaranteed by an “eligible guarantor institution,” as such term is defined below. No signature guarantee is required if either:

• this letter of transmittal is signed by the registered holder(s) of the shares tendered (which, for these purposes, includes any participant in the book-entry transfer facility whose name appears on a security position listing as the owner of the shares) exactly as the name of the registered holder(s) appears on the certificate(s) for the shares and payment and delivery are to be made directly to the holder; or

• the shares are tendered for the account of a bank, broker, dealer, credit union, savings association or other entity which is a member in good standing of the Securities Transfer Agents Medallion Program or a bank, broker, dealer, credit union, savings association or other entity that is also an “eligible guarantor institution,” as that term is defined in Rule 17Ad-15 under the Securities Exchange Act of 1934, as amended, each such entity, referred to as an “eligible guarantor institution.”

In all other cases, including if you have completed either the box entitled “Special Payment Instructions” or “Special Delivery Instructions” above, an eligible guarantor institution must guarantee all signatures on this letter of transmittal. You may also need to have any certificates you deliver endorsed or accompanied by a stock power, and the signatures on these documents also may need to be guaranteed. See instruction 5.

2. Delivery of Letter of Transmittal and Certificates; Guaranteed Delivery Procedures. For your shares to be properly tendered, either (1) or (2) below must happen: (1) The depositary must receive all of the following at its address above in this letter of transmittal before or on the date our offer expires:

• either (a) the certificates for the shares or (b) a confirmation of receipt of the shares pursuant to the procedure for book-entry transfer described in this instruction, and

• either (a) properly completed and executed letter of transmittal or a manually executed facsimile of it, including any required signature guarantees, or (b) an “agent’s message” of the type described in this instruction 2 in the case of a book-entry transfer, and

• any other documents required by this letter of transmittal.

(2) You must comply with the guaranteed delivery procedure set forth below.

Book-Entry Delivery. Any institution that is a participant in the book-entry transfer facility’s system may make book-entry delivery of the shares by causing the book-entry transfer facility to transfer shares into the depositary’s account in accordance with the book-entry transfer facility’s procedures for transfer. Delivery of this letter of transmittal or any other required documents to the book-entry transfer facility does not constitute delivery to the depositary.

Agent’s Message. The term “agent’s message” means a message transmitted by the book-entry transfer facility to, and received by, the depositary, which states that the book-entry transfer facility has received an express acknowledgment from the participant in the book-entry transfer facility tendering the shares that the participant has received and agrees to be bound by the terms of this letter of transmittal and that we may enforce the agreement against them.

Guaranteed Delivery. If you wish to tender your shares but your share certificate(s) are not immediately available or cannot be delivered to the depositary before the offer expires, the procedure for book-entry transfer cannot be completed on a timely basis, or if time will not permit all required documents to reach the depositary before the offer expires, your shares may still be tendered, if all of the following conditions are satisfied:

• the tender is made by or through an eligible guarantor institution;

14 T E N D E R O F F E R S

• the depositary receives by hand, mail, overnight courier or facsimile transmission, before the expiration date, a properly completed and duly executed notice of guaranteed delivery in the form provided with this letter of transmittal, including (where required) a signature guarantee by an eligible guarantor institution in the form set forth in the notice of guaranteed delivery; and

• all of the following are received by the depositary within three New York Stock Exchange trading days after the date of receipt by the depositary of the notice of guaranteed delivery:

• either (a) the certificates for the shares or (b) a confirmation of receipt of the shares pursuant to the procedure for book-entry transfer described in this instruction 2;

• either (a) a properly completed and executed letter of transmittal or a manually executed facsimile of it, including any required signature guarantees, or (b) an “agent’s message” of the type described in this instruction 2 in the case of a book-entry transfer; and

• any other documents required by this letter of transmittal.

The method of delivering all documents, including share certificates, this letter of transmittal and any other required documents, is at your election and risk. If delivery is by mail, we recommend you use registered mail with return receipt requested, properly insured. In all cases, sufficient time should be allowed to ensure timely delivery.

3. Inadequate Space. If the space provided in the box entitled “Description of Shares Tendered” above is inadequate, the certificate numbers and/or the number of shares should be listed on a separate signed schedule and attached to this letter of transmittal.

4. Partial Tenders and Unpurchased Shares. (This paragraph does not apply to shareholders who tender by book-entry transfer.) If fewer than all of the shares evidenced by any certificate are to be tendered, fill in the number of shares that are to be tendered in the column entitled “Number of Shares Tendered” in the box entitled “Description of Shares Tendered” above. In that case, if any tendered shares are purchased, a new certificate for the remainder of the shares (including any shares not purchased) evidenced by the old certificate(s) will be issued and sent to the registered holder(s), unless otherwise specified in either the box entitled “Special Payment Instructions” or “Special Delivery Instructions” in this letter of transmittal, as soon as practicable after the expiration date. Unless otherwise indicated, all shares represented by the certificate(s) set forth above and delivered to the depositary will be deemed to have been tendered.

If any tendered shares are not purchased or are properly withdrawn, or if fewer than all shares evidenced by a shareholder’s certificates are tendered, certificates for unpurchased shares will be returned as soon as practicable after the expiration or termination of the offer or the proper withdrawal of the shares, as applicable. In the case of shares tendered by book-entry transfer at the book-entry transfer facility, the shares will be credited to the appropriate account maintained by the tendering shareholder at the book-entry transfer facility. In each case, we will not charge the shareholder for costs we incur returning or crediting the shares to the shareholder.

5. Signatures on Letter of Transmittal; Stock Powers and Endorsements; Exact Signature. If this letter of transmittal is signed by the registered holder(s) of the shares tendered, the signature(s) must correspond exactly with the name(s) as written on the face of the certificate(s) without any change whatsoever.

Joint Holders. If the shares tendered are registered in the names of two or more joint holders, each holder must sign this letter of transmittal.

Different Names on Certificates. If any tendered shares are registered in different names on several certificates, it will be necessary to complete, sign and submit as many separate letters of transmittal (or manually signed facsimiles) as there are different registrations of certificates.

T E N D E R O F F E R S 15

Endorsements. When this letter of transmittal is signed by the registered holder(s) of the shares tendered, no endorsements of certificates representing the shares or separate stock powers are required unless payment is to be made or the certificates for shares not tendered or not purchased are to be issued to a person other than the registered holder(s). Signature(s) on the certificate(s) must be guaranteed by an eligible institution.

If this letter of transmittal is signed by a person other than the registered holder(s) of the certificates listed, or if payment is to be made or certificates for shares not tendered or not purchased are to be issued to a person other than the registered holder(s), the certificates must be endorsed or accompanied by appropriate stock powers, in either case signed exactly as the name(s) of the registered holder(s) appears on the certificates, and the signatures on the certificates or stock powers must be guaranteed by an eligible institution. See instruction 1.

Signatures of Fiduciaries. If this letter of transmittal or any certificate or stock power is signed by a trustee, executor, administrator, guardian, attorney-in-fact, officer of a corporation or any other person acting in a fiduciary or representative capacity, that person should so indicate when signing and must submit proper evidence satisfactory to us of his or her authority to so act.

6. Stock Transfer Taxes. Except as provided in this instruction 6, no stock transfer tax stamps or funds to cover tax stamps need accompany this letter of transmittal. We will pay any stock transfer taxes payable on the transfer to us of shares purchased pursuant to our offer. If, however,

• payment of the purchase price is to be made to any person other than the registered holder(s);

• shares not tendered or rejected for purchase are to be registered in the name(s) of any person(s) other than the registered holder(s); or

• certificates representing tendered shares are registered in the name(s) of any person(s) other than the person(s) signing this letter of transmittal,

then the depositary will deduct from the purchase price the amount of any stock transfer taxes (whether imposed on the registered holder(s), other person(s) or otherwise) payable on account of the transfer to that person, unless satisfactory evidence of the payment of the taxes or any exemption therefrom is submitted.

7. Special Payment and Delivery Instructions. If certificate(s) for shares not tendered or not purchased and/or check(s) are to be issued in the name of a person other than the signer of this letter of transmittal or if the certificates and/or checks are to be sent to someone other than the person signing this letter of transmittal or to the signer at a different address, the box entitled “Special Payment Instructions” and/or the box entitled “Special Delivery Instructions” on this letter of transmittal should be completed as applicable and signatures must be guaranteed as described in instruction 1.

8. Irregularities. All questions as to the number of shares to be accepted and the validity (including time of receipt), form, eligibility and acceptance for payment of any tender of shares will be determined by us in our sole discretion. Our determination will be final and binding on all parties. We reserve the absolute right to reject any or all tenders of any shares that we determine are not in proper form or the acceptance of or payment for which we determine may be unlawful. We also reserve the absolute right to waive any of the conditions of the offer or any defect or irregularity in any tender with respect to any particular shares or any particular shareholder. No tender of shares will be deemed to be properly made until all defects or irregularities have been cured by the tendering shareholder or waived by us. None of the fund, the depositary, the information agent, or any other person will be under any duty to give notification of any defects or irregularities in any tender, or incur any liability for failure to give any such notification. Our interpretation of the terms of and conditions to the offer, including the letter of transmittal and the these instructions, will be final and binding. By tendering shares to us, you agree to accept all decisions we make concerning these matters and waive any right you might otherwise have to challenge those decisions.

9. Questions and Requests for Assistance and Additional Copies. Questions and requests for additional copies of the offer to purchase, this letter of transmittal or the notice of guaranteed delivery may be directed to the information agent at the telephone number and address set forth the back page of the offer to purchase and set forth below.

16 T E N D E R O F F E R S

10. Federal Income Tax Withholding. To prevent backup federal income tax withholding equal to 28% of the gross payments payable pursuant to the offer, each tendering shareholder who is not a foreign shareholder (as defined below) and who does not otherwise establish an exemption from backup withholding must notify the depositary of the shareholder’s correct taxpayer identification number (employer identification number or social security number), or certify that that taxpayer is awaiting a taxpayer identification number, and provide various other information by completing, under penalties of perjury, the Substitute Form W-9 included in this letter of transmittal. If a shareholder properly certifies that such shareholder is awaiting a taxpayer identification number, 28% of any payment during the 60-day period following the date of the Substitute Form W-9 will be retained by the depositary and, if the shareholder properly furnishes his or her taxpayer identification number within that 60-day period, the depositary will remit the amount retained to such shareholder and will not withhold amounts from future payments under the backup withholding rules. If the shareholder does not properly furnish his or her taxpayer identification number within that 60-day period, the amount retained will be remitted to the IRS as backup withholding and backup withholding will apply to future payments. Foreign shareholders should generally complete and sign an appropriate Form W-8 to avoid backup withholding.

The depositary will withhold United States federal income taxes equal to 30% of the gross payments payable to a foreign shareholder unless the depositary and we determine that an exemption is available. For example, an applicable income tax treaty may reduce or eliminate such tax, in which event a foreign shareholder claiming a reduction in or exemption from such tax under the applicable income tax treaty provides through the third party withholding agent a properly completed IRS Form W-8BEN (or suitable successor form claiming the benefit of the applicable tax treaty). Alternatively, an exemption applies if the gain is effectively connected with a U.S. trade or business of the foreign shareholder and the foreign shareholder provides an appropriate statement to that effect on a properly completed IRS Form W-8ECI (or suitable successor or substitute form). For this purpose, a “foreign shareholder” is any shareholder that is not:

• a citizen or resident of the United States;

• a corporation, partnership, or other entity created or organized in or under the laws of the United States, any State or any political subdivision thereof;

• an estate, the income of which is subject to United States federal income taxation regardless of the source of the income; or

• a trust whose administration is subject to the primary supervision of a United States court and which has one or more United States persons who have the authority to control all of its substantial decisions.

To comply with IRS Circular 230, you are hereby notified that: (a) any discussion of federal tax issues contained or referred to herein is not intended or written to be used, and cannot be used by you, for the purposes of avoiding penalties that may be imposed on you under the Internal Revenue Code; (b) such discussion is written to support the promotion or marketing of the offer addressed by the written advice herein; and (c) you should seek advice based on your particular circumstances from an independent tax advisor.

11. Lost, Stolen, Destroyed or Mutilated Certificates. If your certificate for part or all of your shares has been lost, stolen, misplaced or destroyed, you should contact Putnam Fiduciary Trust Company, the transfer agent for our shares, at 1-800-225-1581 (toll free), for instructions as to obtaining an affidavit of loss. The affidavit of loss will then be required to be submitted together with this letter of transmittal in order to receive payment for shares that are tendered and accepted for payment. A bond may be required to be posted by you to secure against the risk that the certificates may be subsequently recirculated. You are urged to contact Computershare Trust Company, N.A. immediately in order to receive further instructions, to permit timely processing of this documentation and for a determination as to whether you will need to post a bond.

12. Order of Purchase in Event of Proration. As described in Section 1 of the offer to purchase, shareholders can designate in the “Designation” box of this letter of transmittal the order in which they wish to have their shares purchased if, as a result of the proration provisions or otherwise, some but not all of the tendered shares are purchased in the offer. The order of purchase may have an effect on the federal income tax treatment of the purchase price for the shares purchased. See Sections 1 and 5 of the offer to purchase.

T E N D E R O F F E R S 17

• second, after purchase of all of the foregoing shares, all other tendered shares on a pro rata basis (disregarding fractions) in accordance with the number of shares tendered by each shareholder (and not timely withdrawn).

• If your shares are held in street name (i.e., through a broker, dealer or other nominee), you must contact your nominee and request that your shares be tendered in the offer.

• For additional information on the procedures for tendering your shares, see Section 2 of this offer to purchase.

May I tender shares in the offer held in my Dividend Reinvestment Plan account?

• In connection with the offer, the Dividend Reinvestment Plan will be suspended for the regular monthly dividend distributions to be declared in June 2007. The June 2007 dividend will accordingly be paid in cash to all shareholders. We expect that the Dividend Reinvestment Plan will resume for subsequent regular monthly dividends.

Until what time can I withdraw previously tendered shares?

• You can withdraw shares that you tender at any time until the expiration of the offer. Also, if we have not accepted your shares for payment by July 31, 2007, you can withdraw shares at any time after that date until we do accept your shares for payment.

What are the United States federal income tax consequences of tendering shares?

• The receipt of cash for shares pursuant to the offer will be a taxable transaction for United States federal income tax purposes. Depending on a shareholder’s particular circumstances, the sale of shares pursuant to the offer will be treated either as a “sale or exchange” of those shares, producing gain or loss equal to the difference, if any, between the amount of cash received and the shareholder’s adjusted tax basis in the shares sold pursuant to the offer, or as the receipt of a distribution from the fund, taxable as a dividend to the extent of such shareholder’s allocable share of the fund’s “earnings and profits.” There is also a risk of tax consequences for shareholders whose percentage interests in the fund increase as a result of the offer.

See Section 5.

To whom can I talk if I have questions about the tender offer?

• You can call the information agent at (212) 440-9800 (for banks or brokers) or toll-free at (866) 651-3106. See the back cover of this offer to purchase.

Dear Shareholder:

INTRODUCTION

Putnam Municipal Opportunities Trust, a Massachusetts business trust registered under the Investment Company Act of 1940, as amended, as a closed-end, non-diversified management investment company, hereby offers to purchase up to 1,517,251 of the fund’s outstanding common shares at a price per share, net to the seller in cash, equal to 98% of the net asset value per share in U.S. dollars as of the close of regular trading on the New York Stock Exchange on July 12, 2007, or such later date to which the offer is extended, upon the terms and subject to the conditions set forth in this offer to purchase and in the related letter of transmittal. The maximum number of shares that we will purchase in the tender offer represents approximately 10% of the number of currently outstanding shares.

This offer is open to all common shareholders of the fund and is not conditioned on any minimum number of shares being tendered but is subject to other conditions as outlined in this offer to purchase and in the letter of transmittal. See Section 12 of this offer to purchase.

None of the fund, its board of trustees or its investment manager makes any recommendation as to whether you should tender or not tender shares in the offer. No person has been authorized to give any information or to make any representations in connection with the offer other than those contained in this offer to purchase and in the letter of transmittal, and, if given or made, such information or representations should not be relied upon as having been authorized by the fund, its board of trustees or its investment manager. We have been advised that no trustee or executive officer of the fund intends to tender any shares pursuant to the offer.

As of May 11, 2007, there were 15,172,510 shares issued and outstanding, and the net asset value was $13.21 per share. We do not expect that the number of shares issued and outstanding will be materially different on the date the offer expires. Shareholders may contact the information agent, toll free at (866) 651-3106 or, for banks and brokers, at (212) 440-9800 or contact the fund directly at its toll free number, 1-800-225-1581, to obtain daily net asset value quotations for the shares prior to 5:00 p.m., New York City time, on the expiration date.

Any shares we acquire pursuant to the offer will become authorized but unissued shares and generally will be available for issuance by the fund without further shareholder action.

Tendering shareholders may be obligated to pay brokerage fees or commissions or, subject to Instruction 6 of the letter of transmittal, transfer taxes on the purchase of shares by the fund. Shareholders may also be subject to other transaction costs, as described in Section 1.

Certain U.S. federal income tax consequences of the sale of shares pursuant to the offer are described in Section 5 “U.S. Federal Income Tax Consequences.”

This offer to purchase and the letter of transmittal contain important information and you should read them carefully and in their entirety before you make any decision with respect to the offer.

THE TENDER OFFER

1. Terms of the Offer

Upon the terms and subject to the conditions set forth in this offer to purchase and the letter of transmittal, the fund will accept for payment, and pay for, up to 1,517,251 shares, validly tendered prior to 5:00 p.m., New York City time, on July 12, 2007, or such later date to which the offer is extended, and not withdrawn as permitted by Section 3.

If the number of shares properly tendered and not withdrawn prior to the expiration date is less than or equal to 1,517,251, we will, upon the terms and conditions of the offer, purchase all shares so tendered. If more than 1,517,251 shares are duly tendered pursuant to the offer (and not withdrawn as provided in Section 3), unless we determine not to purchase any shares because one or more conditions described in Section 12 of this offer to purchase are not met, we will purchase shares in the following priority: first, all such shares owned beneficially or of record by a holder of fewer than 100 common shares who validly tenders all of such shares (partial tenders will not qualify for this preference) and completes, or whose broker, bank or other nominee completes, the section captioned “Odd Lots” in the letter of transmittal and, if applicable, in the notice of guaranteed delivery; and, second, after purchase of all of the foregoing shares, all other shares duly tendered on a pro rata basis (disregarding fractions) in accordance with the number of shares duly tendered by or on behalf of each shareholder (and not withdrawn). On the letter of transmittal, you can designate in which order you wish your shares to be purchased if, as a result of the proration provisions or otherwise, some but not all of your tendered shares are purchased in the offer. If shares duly tendered by or on behalf of a shareholder include shares acquired through the fund’s dividend reinvestment plan, the proration will be applied first against other shares tendered and only thereafter, if and as necessary, with respect to shares acquired through that plan. Except as described herein, withdrawal rights expire on the expiration date. The fund does not contemplate extending the offer or increasing the number of shares covered by the offer if more than 1,517,251 shares are tendered.

Shareholders should consider the relative costs of tendering shares at a 2% discount to net asset value pursuant to the offer or selling shares at the market price with the associated transaction costs.

We expressly reserve the right, in our sole discretion, at any time or from time to time, to extend the period of time during which the offer is open by giving oral or written notice of such extension to the depositary. Any such extension will also be publicly announced by press release issued no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration date. If we make a material change in the terms of the offer or the information concerning the offer, or if we waive a material condition of the offer, we will extend the offer to the extent required by Rules 13e-4(d)(2) and 13(e)-4(e)(3) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). During any such extension, all shares previously tendered and not withdrawn will remain subject to the offer, subject to the right of any such tendering shareholder to withdraw his or her shares.

Subject to the terms and conditions of the offer, we will pay the consideration offered or return the tendered securities promptly after the expiration or withdrawal of the offer. Any extension, delay or expiration will be followed as promptly as practicable by public announcement thereof.

Under no circumstances will interest be paid on the tender price for tendered shares, regardless of any extension of or amendment to the offer or any delay in paying for such shares.

2. Procedures for Tendering Shares

Proper Tender of Shares. For shares to be properly tendered, either (1) or (2) below must happen:

(1) The depositary must receive all of the following prior to 5:00 p.m., New York City time, on the expiration date at the depositary’s address on the back page of this offer to purchase:

• either (a) the certificates for the shares, or (b) in the case of tendered shares delivered in accordance with the procedures for book-entry transfer we describe below, a confirmation of receipt of the shares; and

2 T E N D E R O F F E R S

• either (a) a properly completed and executed letter of transmittal or a manually executed facsimile of it, including any required signature guarantees, or (b) in the case of a book-entry transfer, an “agent’s message” of the type we describe below; and

• any other documents required by the letter of transmittal.

(2) You must comply with the guaranteed delivery procedure set forth below.

Odd lot holders who tender all their shares must also complete the section captioned “Odd Lots” in the letter of transmittal and, if applicable, in the notice of guaranteed delivery, to qualify for the preferential treatment available to odd lot holders as set forth in Section 1.

Endorsements and Signature Guarantees. Depending on how your shares are registered and to whom you want payments or deliveries made, you may need to have your certificates endorsed and the signatures on the letter of transmittal and endorsement guaranteed by an “eligible guarantor institution,” as such term is defined in Rule 17Ad-15 under the Exchange Act. No endorsement or signature guarantee is required if:

• the letter of transmittal is signed by the registered holder of the shares tendered (which, for purposes of this Section 3, includes any participant in The Depository Trust Company, referred to as the “book-entry transfer facility,” whose name appears on a security position listing as the owner of the shares) exactly as the name of the registered holder appears on the certificate(s) for the shares and payment and delivery are to be made directly to that holder; or

• shares are tendered for the account of a bank, broker, dealer, credit union, savings association or other entity that is a member in good standing of the Securities Transfer Agents Medallion Program or a bank, broker, dealer, credit union, savings association or other entity that is also an “eligible guarantor institution,” as such term is defined in Rule 17Ad-15 under the Exchange Act, each such entity, referred to as an “eligible guarantor institution.” See Instruction 1 of the letter of transmittal.

If a certificate for shares is registered in the name of a person other than the person executing the letter of transmittal or you are completing either the box captioned “Special Delivery Instructions” or the box captioned “Special Payment Instructions” in the letter of transmittal, then:

• your certificates must be endorsed or accompanied by an appropriate stock power, in either case signed exactly as the name of the registered holder appears on the certificates; and

• the signature on (1) the letter of transmittal and (2) your endorsed certificates or stock power must be guaranteed by an eligible guarantor institution.

Method of Delivery. Payment for shares tendered and accepted for payment under the offer will be made only after timely receipt by the depositary of all of the following:

• certificates for those shares or a timely confirmation of the book-entry transfer of those shares into the depositary’s account at the book-entry transfer facility as described below;

• one of (a) a properly completed and duly executed letter of transmittal or a manually signed facsimile of it, including any required signature guarantees, or (b) an agent’s message as described below in the case of a book-entry transfer; and

• any other documents required by the letter of transmittal.

The method of delivery of all documents, including share certificates, the letter of transmittal and any other required documents, is at your election and risk. If you decide to make delivery by mail, we recommend you use registered mail with return receipt requested, properly insured. In all cases, sufficient time should be allowed to ensure timely delivery.

T E N D E R O F F E R S 3

All deliveries made in connection with the offer, including a letter of transmittal and certificates for shares, must be made to the depositary and not to the fund, the fund’s transfer agent, the information agent or the book-entry transfer facility. Any documents delivered to the fund, the fund’s transfer agent, the information agent or the book-entry transfer facility will not be forwarded to the depositary and, therefore, will not be deemed to have been properly tendered.

Book-Entry Delivery. The depositary will establish an account with respect to the shares at the book-entry transfer facility for purposes of the offer within two business days after the date of this offer to purchase. Any institution that is a participant in the book-entry transfer facility’s system may make book-entry delivery of the shares by causing that facility to transfer those shares into the depositary’s account in accordance with that facility’s procedure for the transfer. Even if delivery of shares is made through book-entry transfer into the depositary’s account at the book-entry transfer facility, either (1) or (2) below must occur:

(1) The depositary must receive all of the following before or on the expiration date at the depositary’s address on the back page of this offer to purchase:

• one of (a) a properly completed and executed letter of transmittal or a manually executed facsimile of it, including any required signature guarantees, or (b) an agent’s message as described below in the case of a book-entry transfer; and

• any other documents required by the letter of transmittal; or

(2) The guaranteed delivery procedure described below must be followed.

Delivery of the letter of transmittal or any other required documents to the book-entry transfer facility does not constitute delivery to the depositary.

The term “agent’s message” means a message transmitted by the book-entry transfer facility to, and received by, the depositary, which states that the book-entry transfer facility has received an express acknowledgement from the participant in the book-entry transfer facility tendering the shares that the participant in the book-entry transfer facility tendering the shares has received and agrees to be bound by the terms of the letter of transmittal and that we may enforce that agreement against them.

Guaranteed Delivery. If you want to tender your shares but your share certificates are not immediately available or cannot be delivered to the depositary before the expiration date, the procedure for book-entry transfer cannot be completed on a timely basis, or if time will not permit all required documents to reach the depositary before the expiration date, you can still tender your shares, if all of the following conditions are satisfied:

• the tender is made by or through an eligible guarantor institution;

• the depositary receives by hand, mail, overnight courier or facsimile transmission, prior to the expiration time, a properly completed and duly executed notice of guaranteed delivery in the form we have provided with this offer to purchase, including (where required) signature guarantees by an eligible guarantor institution in the form set forth in the notice of guaranteed delivery; and

• all of the following are received by the depositary within three New York Stock Exchange trading days after the date of receipt by the depositary of the notice of guaranteed delivery, either:

• the certificates representing the shares being tendered together with (a) a letter of transmittal, or a facsimile thereof, relating thereto that has been validly completed and duly executed and includes all signature guarantees required thereon and (b) all other required documents; or

• in the case of any book-entry transfer of the shares being tendered that is effected in accordance with the book-entry transfer procedures we describe above under “Book-Entry Delivery:” (a) a letter of transmittal or a facsimile thereof, relating thereto that has been validly completed and duly executed and includes all signature guarantees required thereon, or an agent’s message, (b) a book-entry confirmation relating to that transfer, and (c) all other required documents.

4 T E N D E R O F F E R S

Determination of Validity; Rejection of Shares; Waiver of Defects; No Obligation to Give Notice of Defects. We will determine, in our sole discretion, all questions as to the number of shares to be accepted, and the validity, form, eligibility, including time of receipt, and acceptance for payment of any tender of shares. Our determination will be final and binding on all parties. We reserve the absolute right to reject any or all tenders we determine not to be in proper form or the acceptance of or payment for which we determine may be unlawful. We also reserve the absolute right to waive any of the conditions of the offer and any defect or irregularity in the tender of any particular shares or any particular shareholder. No tender of shares will be deemed to be properly made until all defects or irregularities have been cured by the tendering shareholder or waived by us. None of the fund, the depositary, the information agent, or any other person will be under any duty to give notice of any defects or irregularities in any tender, or incur any liability for failure to give any such notice. Our interpretation of the terms of and conditions to the offer, including the letter of transmittal and the instructions thereto, will be final and binding. By tendering shares to us, you agree to accept all decisions we make concerning these matters and waive any right you might otherwise have to challenge those decisions.

Your Representation and Warranty; Our Acceptance Constitutes an Agreement. It is a violation of Rule 14e-4 promulgated by the Securities and Exchange Commission under the Exchange Act for a person, acting alone or in concert with others, directly or indirectly, to tender shares for that person’s own account unless, at the expiration date, the person so tendering:

• within the meaning of Rule 14e-4, has a “net long position” equal to or greater than the amount tendered in our shares or in securities immediately convertible into, or exchangeable or exercisable for, our shares; and

• will deliver or cause to be delivered the shares within the period specified in the offer; or

• in the case of securities immediately convertible into, or exchangeable or exercisable for our shares, acquires shares by conversion, exchange or exercise of such securities, and, to the extent required by the terms of the offer, delivers or causes to be delivered the shares within the period specified by the offer.

Rule 14e-4 provides a similar restriction applicable to the tender or guarantee of a tender on behalf of another person.

A tender of shares under any of the procedures described above will constitute your acceptance of the terms and conditions of the offer, as well as your representation and warranty to us that:

• you have a “net long position” in the shares or equivalent securities at least equal to the shares tendered; and

• the tender of shares complies with Rule 14e-4.

Our acceptance for payment of shares tendered under the offer will constitute a binding agreement between you and us upon the terms and conditions of the offer described in this and related documents.

Return of Unpurchased Shares. If any tendered shares are not purchased or are properly withdrawn, or if less than all shares evidenced by a shareholder’s certificates are tendered, certificates for unpurchased shares will be returned promptly after the expiration or termination of the offer or the proper withdrawal of the shares, as applicable. In the case of shares tendered by book-entry transfer at the book-entry transfer facility, the shares will be credited to the appropriate account maintained by the tendering shareholder at the book-entry transfer facility. In each case, we will not charge the shareholder for costs we incur returning or crediting the shares to the shareholder.

Procedures for Participants in the Dividend Reinvestment Plan. Holders of shares acquired through the fund’s dividend reinvestment plan may instruct the depositary to tender such shares by completing the appropriate section of the letter of transmittal. If a shareholder tenders shares acquired through the dividend reinvestment plan, all such shares credited to such shareholder’s account(s) will be tendered, unless the shareholder otherwise specifies in the letter of transmittal. If a shareholder does not complete the section of the letter of transmittal instructing the depositary to tender shares acquired through the dividend reinvestment plan, no shares acquired by that shareholder through the dividend reinvestment plan will be tendered.

T E N D E R O F F E R S 5

Lost or Destroyed Certificates. If your certificate for part or all of your shares has been lost, stolen, misplaced or destroyed, you should contact Putnam Fiduciary Trust Company, the transfer agent of the fund, at 1-800-225-1581 (toll free), for instructions as to obtaining an affidavit of loss. The affidavit of loss will then be required to be submitted together with the letter of transmittal in order to receive payment for shares that are tendered and accepted for payment. A bond may be required to be posted by you to secure against the risk that the certificates may be subsequently recirculated. You are urged to contact the depositary immediately in order to receive further instructions, to permit timely processing of this documentation and for a determination as to whether you will need to post a bond.

Backup Withholding. In order to avoid “backup withholding” of U.S. federal income tax on payments of cash pursuant to the offer, a shareholder surrendering shares in the offer must, unless an exemption applies, provide the depositary with such shareholder’s correct taxpayer identification number on a Substitute Form W-9, certify under penalties of perjury that such tax identification number is correct and provide certain other certifications. If a shareholder does not provide such shareholder’s correct tax identification number or fails to provide the required certifications, the Internal Revenue Service may impose a penalty on such shareholder and payment of cash to such shareholder pursuant to the offer may be subject to backup withholding of 28%. All shareholders surrendering shares pursuant to the offer should complete and sign the main signature form and the Substitute Form W-9 included as part of the letter of transmittal to provide the information and certification necessary to avoid backup withholding. Certain shareholders (including, among others, all corporations, individual retirement accounts and certain foreign individuals and entities) are not subject to backup withholding; however, such shareholders should complete the Substitute Form W-9 to avoid possible erroneous backup withholding. Noncorporate foreign shareholders should complete and sign the main signature form and an appropriate Form W-8 (instead of a Form W-9), a copy of which may be obtained from the depositary, in order to avoid backup withholding. See instruction 10 to the letter of transmittal.

3. Withdrawal Rights

Shares tendered pursuant to the offer may be withdrawn pursuant to the procedures set forth below at any time prior to the expiration date and, unless already accepted for payment pursuant to the offer, at any time on or after July 12, 2007.

For a withdrawal to be effective, a written or facsimile transmission notice of withdrawal must be timely received by the depositary at one of its addresses set forth on the back cover of this offer to purchase and must specify the name of the person having tendered the shares to be withdrawn, the number of shares to be withdrawn and the name of the registered holder of the shares to be withdrawn, if different from the name of the person who tendered the shares. If certificates for shares have been delivered or otherwise identified to the depositary, then, prior to the physical release of such certificates, the serial numbers shown on such certificates must be submitted to the depositary and, unless such shares have been tendered by an eligible institution, any and all signatures on the notice of withdrawal must be guaranteed by an eligible institution. If shares have been tendered pursuant to the book-entry transfer procedures described in Section 2, any notice of withdrawal must also specify the name and number of the account at the book-entry transfer facility to be credited with the withdrawn shares and otherwise comply with the book-entry transfer facility’s procedures. Withdrawals of tenders of shares may not be rescinded, and any shares validly withdrawn will thereafter be deemed not validly tendered for purposes of the offer. However, withdrawn shares may be retendered by again following one of the procedures described in Section 2 at any time prior to the expiration date.

All questions as to the form and validity (including time of receipt) of any notice of withdrawal will be determined by the fund in its sole discretion, which determination will be final and binding. None of the fund, the depositary, the information agent, or any other person will be under any duty to give notification of any defects or irregularities in any notice of withdrawal or incur any liability for failure to give any such notification.

The method of delivery of any documents related to a withdrawal is at the risk of the withdrawing shareholder. Any documents related to a withdrawal will be deemed delivered only when actually received by the depositary. If delivery is by mail, registered mail with return receipt requested, properly insured, is recommended. In all cases, sufficient time should be allowed to ensure timely delivery.

4. Acceptance for Payment and Payment

Upon the terms and subject to the conditions of the offer, we will accept for payment, and will pay cash for, shares validly tendered on or before the expiration date, and not properly withdrawn in accordance with Section 3, promptly after the expiration date. In all cases, payment for shares tendered and accepted for payment pursuant to the offer will be made only after timely receipt by the depositary of certificates for such shares (unless such shares are held in uncertificated form), a properly completed and duly executed letter of transmittal (or facsimile thereof), and any other documents required by the letter of transmittal. We expressly reserve the right, in our sole discretion, to delay the acceptance for payment of, or payment for, shares, in order to comply, in whole or in part with any applicable law.

For purposes of the offer, we will be deemed to have accepted for payment shares validly tendered and not withdrawn as, if and when we give or cause to be given oral or written notice to the depositary of our acceptance for payment of such shares pursuant to the offer. Payment for shares accepted for payment pursuant to the offer will be made by deposit of the aggregate purchase price therefor with the depositary, which will act as agent for the tendering shareholders for purpose of receiving payments from the fund and transmitting such payments to the tendering shareholders. Under no circumstances will interest on the purchase price for shares be paid, regardless of any delay in making such payment.

In the event of proration, we will determine the proration factor and pay for those tendered shares accepted for payment as soon as practicable after the expiration date. However, we expect that we will not be able to announce the final results of any proration or commence payment for any shares purchased pursuant to the offer until at least five business days after the expiration date.

If any tendered shares are not accepted for payment pursuant to the terms and conditions of the offer for any reason, or are not accepted because of an invalid tender, or if certificates are submitted for more shares than are accepted (i) certificates for such unpurchased shares will be returned, without charge by us to the tendering shareholder, as soon as practicable following expiration or termination of the offer, (ii) shares delivered pursuant to the book-entry delivery procedure (as defined in Section 2 above) will be credited to the appropriate account maintained within the book-entry transfer facility and (iii) uncertificated shares held by the fund’s transfer agent pursuant to the fund’s dividend reinvestment plan will be returned to the dividend reinvestment plan account maintained by the transfer agent.

If we are delayed in our acceptance for payment of, or in our payment for, shares, or are unable to accept for payment or pay for shares pursuant to the offer for any reason, then, without prejudice to our rights under this offer, the depositary may, on behalf of the fund, retain tendered shares, and such shares may not be withdrawn, unless and except to the extent tendering shareholders are entitled to withdrawal rights as described in Section 3 of this offer to purchase.

The purchase price of the shares will equal 98% of their net asset value (a 2% discount) as of the close of regular trading on the New York Stock Exchange on July 12, 2007, or such later date to which the offer is extended. Tendering shareholders may be required to pay brokerage commissions or fees. Under the circumstances set forth in Instruction 6 of the letter of transmittal, shareholders may be subject to transfer taxes on the purchase of shares by the fund.

We normally calculate the net asset value of our shares daily at the close of regular trading of the New York Stock Exchange. On May 17, 2007, the net asset value was $13.16 per share. The shares are listed on the New York Stock Exchange. On May 17, 2007, the last sales price at the close of regular trading on the New York Stock Exchange was $12.26 per share, representing a 6.84% discount from net asset value. The net asset value of the shares will be available daily until the expiration date, by calling the information agent, toll free at (866) 651-3106 or, for banks or brokers, at (212) 440-9800 or through the fund’s toll free number at 1-800-225-1581.

5. Certain U.S. Federal Income Tax Consequences

The following discussion describes certain U.S. federal income tax consequences of the sale of shares pursuant to the offer. Except where noted, it deals only with shares held as capital assets and does not deal with special situations, such as those of dealers in securities or commodities, traders in securities that elect to mark their holdings to market, insurance companies, persons holding shares as a part of a hedging, conversion or constructive sale transaction or a straddle, or shareholders whose functional currency is not the U.S. dollar. Furthermore, the discussion below is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), and regulations, rulings and judicial decisions thereunder as of the date hereof, and such authorities may be repealed, revoked or modified so as to result in U.S. federal income tax consequences different from those discussed below. Shareholders should consult their own tax advisors concerning the U.S. federal income tax consequences of participating in the offer in light of their particular situations as well as any consequences arising under the laws of any other taxing jurisdiction.

As used herein, a “U.S. Shareholder” means a shareholder that is (i) a citizen or resident of the U.S., (ii) a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes), partnership, or other entity created or organized in or under the laws of the U.S., any State or any political subdivision thereof, (iii) an estate the income of which is subject to U.S. federal income taxation regardless of the source of the income, or (iv) a trust if it (x) is subject to the supervision of a court within the U.S. and one or more U.S. persons has the authority to control all substantial decisions of the trust or (y) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person. A “Non-U.S. Shareholder” is a shareholder that is not a U.S. Shareholder.

An exchange of shares for cash in the offer will be a taxable transaction for U.S. federal income tax purposes. As a consequence of the exchange, depending on a shareholder’s particular circumstances, the sale of shares pursuant to the offer will be treated either as a “sale or exchange” producing gain or loss or as the receipt of a distribution from the fund taxable as a dividend to the extent of such shareholder’s allocable share of the fund’s “earnings and profits.” Under Section 302(b) of the Code, a sale of shares pursuant to the offer generally will be treated as a sale or exchange if the receipt of cash by the shareholder: (a) results in a complete termination of the shareholder’s interest in the fund, (b) results in a “substantially disproportionate” redemption with respect to the shareholder, or (c) is “not essentially equivalent to a dividend” with respect to the shareholder. For this purpose a “substantially disproportionate” redemption is one that reduces the shareholder’s percentage voting interest in the fund by more than 20% and after which the shareholder owns a less-than-50% voting interest in the fund. Also for this purpose, a redemption is “not essentially equivalent to a dividend” if it results in a “meaningful reduction” of a shareholder’s percentage interest in the fund. Whether a reduction is “meaningful” depends on a shareholder’s particular facts and circumstances; in general, the smaller a shareholder’s percentage interest in the fund, the more likely it is that any such reduction therein will be treated as “meaningful.” In determining whether any of these tests has been met, shares actually owned, as well as shares considered to be owned by the shareholder by reason of certain constructive ownership rules set forth in Section 318 of the Code, generally must be taken into account. If any of these three tests for sale or exchange treatment under Section 302(b) is met, a shareholder will recognize gain or loss equal to the difference between the price paid by the fund for the shares purchased in the offer and the shareholder’s adjusted basis in such shares. If such shares are held as a capital asset, the gain or loss will be capital gain or loss. The maximum tax rate applicable to capital gains recognized by individuals and other non-corporate taxpayers is (i) the same as the applicable ordinary income rate for capital assets held for one year or less or (ii) 15% for capital assets held for more than one year. The deductibility of capital losses is subject to limitations.

If the requirements of Section 302(b) of the Code are not met, amounts received by a shareholder who sells shares pursuant to the offer will be taxable to the shareholder as a dividend to the extent of such shareholder’s allocable share of the fund’s current or accumulated earnings and profits. To the extent that amounts received exceed such shareholder’s allocable share of the fund’s current and accumulated earnings and profits for a taxable year,

8 T E N D E R O F F E R S

the distribution will first be treated as a non-taxable return of capital, causing a reduction in the adjusted basis of such shareholder’s shares, and any amounts in excess of the shareholder’s adjusted basis will constitute taxable gain. Any remaining adjusted basis in the shares tendered to the fund will be transferred to any remaining shares held by such shareholder.

Provided that no tendering shareholder is treated as receiving a dividend as a result of selling shares pursuant to the offer, shareholders who do not sell shares pursuant to the offer will not realize any taxable income. In the event that any shareholder is deemed to receive a dividend as a result of selling shares pursuant to the offer, there is a risk that shareholders whose percentage interests in the fund increase as a result of the offer (whether because they do not tender shares pursuant to the offer, or sell fewer shares than other shareholders) may be deemed to have received a constructive distribution from the fund under Section 305 of the Code, in an amount equal to the increase in such shareholder’s percentage ownership of the fund that is taxable as a dividend to the extent of such shareholder’s allocable share of the fund’s earnings and profits.

Backup Federal Income Tax Withholding. Backup withholding tax will be imposed on the gross proceeds paid to a tendering U.S. Shareholder unless the U.S. Shareholder provides such U.S. Shareholder’s taxpayer identification number (employer identification number or social security number) to the depositary, certifies as to no loss of exemption from backup withholding, complies with applicable requirements of the backup withholding rules or is otherwise exempt from backup withholding. Therefore, each tendering U.S. Shareholder should complete and sign the Substitute Form W-9 included as part of the letter of transmittal so as to provide the information and certification necessary to avoid backup withholding. Certain U.S. Shareholders (including, among others, all corporations) are not subject to these backup withholding requirements; however, such shareholders should complete the Substitute Form W-9 to avoid erroneous backup withholding. In addition, Non-U.S. Shareholders are subject to these withholding requirements. In order for a Non-U.S. Shareholder to qualify as an exempt recipient, that Non-U.S. Shareholder must submit an IRS Form W-8 or a Substitute Form W-8. Such statements can be obtained from the depositary.

To prevent backup U.S. federal income tax withholding, each shareholder who does not otherwise establish an exemption from such withholding must provide the depositary with the shareholder’s correct taxpayer identification number and provide certain other information by completing the Substitute Form W-9 included in the letter of transmittal.

Withholding for Non-U.S. Shareholders. Even if a Non-U.S. Shareholder has provided the required certification to avoid backup withholding, the depositary will withhold U.S. federal income tax equal to 30% of the gross payments payable to a Non-U.S. Shareholder or his or her agent unless the depositary determines that a reduced rate of withholding is available pursuant to a tax treaty or that an exemption from withholding is applicable because such gross proceeds are effectively connected with the conduct of a trade or business within the U.S. In order to obtain a reduced rate of withholding pursuant to a tax treaty, a Non-U.S. Shareholder must deliver to the depositary before the payment a properly completed and executed IRS Form W-8BEN. In order to obtain an exemption from withholding on the grounds that the gross proceeds paid pursuant to the offer are effectively connected with the conduct of a trade or business within the U.S., a Non-U.S. Shareholder must deliver to the depositary a properly completed and executed IRS Form W-8ECI. The depositary will determine a shareholder’s status as a Non-U.S. Shareholder and eligibility for a reduced rate of, or exemption from, withholding by reference to any outstanding certificates or statements concerning eligibility for a reduced rate of, or exemption from, withholding (e.g., IRS Forms W-8BEN or W-8ECI) unless facts and circumstances indicate that such reliance is not warranted. A Non-U.S. Shareholder may be eligible to obtain a refund of all or a portion of any tax withheld if such shareowner meets the “complete redemption,” “substantially disproportionate” or “not essentially equivalent to a dividend” test described above or is otherwise able to establish that no tax or a reduced amount of tax is due. Backup withholding generally will not apply to amounts subject to the 30% or a treaty-reduced rate of withholding. Non-U.S. Shareholders are urged to consult their own tax advisors regarding the application of U.S. federal income tax withholding, including eligibility for a withholding tax reduction or exemption, and the refund procedure.

6. Net Asset Value and Market Price Range of the Shares; Dividends on the Shares

The shares are traded on the New York Stock Exchange. The following table sets forth for the periods indicated the net asset value (as of the last day of each such period), and the high and low price per share on the New York Stock Exchange during each such period:

				Net Asset
First Quarter Ended	High	Low		Value

April 30, 2007	$12.38	$12.04	$13.19
January 31, 2007	12.10	11.64	13.16
October 31, 2006	11.78	11.29	13.28
July 31, 2006	11.67	11.03	12.90
April 30, 2006	11.92	11.60	12.85
January 31, 2006	11.80	11.14	13.02
October 31, 2005	11.99	11.40	12.92
July 31, 2005	12.19	11.68	13.20

The tender of shares, unless and until such tendered shares are accepted for purchase, will not affect the record ownership of any such tendered shares for purposes of entitlement to any dividends payable by the fund.

On May 17, 2007, the net asset value was $13.16 per share and the reported sales price on the New York Stock Exchange was $12.26 per share, representing a 6.84% discount from net asset value. Shareholders are urged to obtain current market quotations for the shares.

7. Source and Amount of Funds; Effect of the Offer

Cost to the Fund. The actual cost of the offer to the fund cannot be determined at this time because the number of shares to be purchased will depend on the number tendered, and the price will be based on the net asset value per share on the expiration date. If the net asset value per share on the expiration date were the same as the net asset value per share on May 17, 2007, and if shareholders tender 1,517,251 shares, the maximum number of securities we will purchase pursuant to the offer, the estimated payment by the fund to the shareholders would be approximately $19,572,538. See the Pro Forma Capitalization Table below.

The monies we use to purchase shares in the offer will be obtained from cash and from sales of securities in the fund’s investment portfolio. There are no financing conditions to this offer.

Effect on Net Asset Value and Consideration Received by Tendering Shareholders.

The offer may have certain adverse consequences for tendering and non-tendering shareholders.

If the fund were required to sell a substantial amount of portfolio securities to raise cash to finance the offer, the market prices of portfolio securities being sold and/or the fund’s remaining portfolio securities may decline and hence the fund’s net asset value may decline. If any such decline occurs, we cannot predict what its magnitude would be or whether such a decline would be temporary or continue to or beyond the expiration date. Because the price per share to be paid in the offer will be dependent upon the net asset value per share as determined on the expiration date, if such a decline continued up to the expiration date, the consideration received by tendering shareholders would be reduced. In addition, the sale of portfolio securities will cause the fund to incur increased brokerage and related transaction expenses, and the fund may receive proceeds from the sale of portfolio securities less than their valuations by the fund. Accordingly, obtaining the cash to consummate the offer may result in a decrease in the fund’s net asset value per share, thereby reducing the amount of proceeds received by tendering shareholders and the net asset value per share for non-tendering shareholders.

10 T E N D E R O F F E R S

Shareholders should note, however, that the offer may result in accretion to the fund’s net asset value per share following the offer, due to the fact that the tender price would represent a 2% discount to the fund’s net asset value per share at that time. The potential accretion to the fund’s net asset value per share may offset, in whole or in part, any decline in the fund’s net asset value as discussed above and the expenses of the offer.

The fund will likely sell portfolio securities during the pendency of the offer to raise cash for the purchase of shares. During the pendency of the offer, consequently, and possibly after that, the fund will likely hold a greater than normal percentage of its net assets in cash and cash equivalents. The fund will pay for tendered shares it accepts for payment promptly after the expiration date of this offer. Because the fund will not know the number of shares tendered until the expiration date, the fund will not know until the expiration date the amount of cash required to pay for such shares. If on or prior to the expiration date, the fund does not have, or believes it is unlikely to have, sufficient cash to pay for all shares tendered, it may extend the offer to allow additional time to sell portfolio securities and raise sufficient cash.

Recognition of Capital Gains by the Fund. As noted above, the fund will likely be required to sell portfolio securities to finance the offer. If the fund’s tax basis for the securities sold is less than the sale proceeds, the fund will recognize capital gains. The fund would expect to declare and distribute any such gains to shareholders of record (reduced by net capital losses realized during the fiscal year, if any). In addition, some of the distributed gains may be realized on securities held for one year or less, which would generate income taxable to the non-tendering shareholders at ordinary income rates. This recognition and distribution of gains, if any, would have certain negative consequences. First, shareholders remaining at the time of a declaration of distributions would be required to pay taxes on a greater amount of distributions than otherwise would be the case. Second, to raise cash to make the distributions, the fund might need to sell additional portfolio securities thereby possibly being forced to realize and recognize additional capital gains. It is impossible to predict what the amount of unrealized gains or losses would be in the fund’s portfolio at the time that the fund is required to liquidate portfolio securities (and the amount of capital gains or losses that would be realized and recognized). As of March 31, 2007, there was net unrealized appreciation of $15,550,985 in the fund’s portfolio as a whole, and as of March 31, 2007, there were net capital loss carryforwards of $(20,951,808) that for tax purposes would offset future gains actually realized.

Tax Consequences of Repurchases to Shareholders. Our purchase of tendered shares pursuant to the offer will have tax consequences for tendering shareholders and may have tax consequences for non-tendering shareholders (or in certain cases tendering shareholders whose percentage interests in the fund nonetheless increase as a result of the offer). See Section 5 of this offer to purchase.

Higher Expense Ratio and Less Investment Flexibility. If we purchase a substantial number of shares pursuant to the offer, the net assets of the fund will be reduced accordingly. The reduced net assets of the fund as a result of the offer will result in a higher expense ratio for the fund and possibly in less investment flexibility for the fund.

Reduction in Shares Outstanding. Our purchase of shares in the offer will reduce the number of our shares that might otherwise trade publicly and may reduce the number of our shareholders. Assuming the offer is fully subscribed, we will have approximately 13,655,259 shares outstanding following the purchase of shares tendered in the offer. The actual number of shares outstanding will depend on the number of shares tendered and purchased in the offer. This may reduce the volume of trading in the shares and make it more difficult to buy or sell significant amounts of shares without affecting the market price, which could adversely affect continuing shareholders.

The shares are currently “margin securities” under the rules of the Federal Reserve Board. This has the effect, among other things, of allowing brokers to extend credit on the collateral of the shares. We believe that, following the purchase of shares pursuant to the offer, the shares will continue to be “margin securities” for purposes of the Federal Reserve Board’s margin regulations.

T E N D E R O F F E R S 11

Our shares are registered under the Exchange Act, which requires, among other things, that we furnish specific information to our shareholders and to the Securities and Exchange Commission and comply with the Securities and Exchange Commission’s proxy rules in connection with meetings of our shareholders. We believe that our purchase of shares in the offer will not result in the shares becoming eligible for deregistration under the Exchange Act.

Pro Forma Effects on Capitalization. The following table sets forth the net assets of the fund as of October 31, 2006, adjusted to give effect to the offer (excluding expenses and assuming we repurchase 1,536,660 outstanding shares):

Pro Forma Capitalization (1)
		Adjustment for
	As of	Purchase at $13.01	Pro Forma as
	October 31, 2006	Per Share (2)	Adjusted (1)

Total net assets (3)	$204,137,709	($19,991,947)	$184,145,762
Common shares outstanding	15,366,599	(1,536,660)	13,829,939
Net asset value per share (4)	$13.28	$13.01	$13.32

(1) This table assumes purchase by the fund of 1,536,660 shares, equal to approximately 10% of the fund’s outstanding shares as of October 31, 2006. The number of shares as of May 11, 2007 that the fund is offering to purchase is smaller due to share repurchases made by the fund in the interim pursuant to the repurchase program authorized by the fund's board of trustees in October 2005.

(2) This amount represents 98% of the fund’s net asset value as determined on October 31, 2006. Shares tendered pursuant to the offer will be purchased at a 2% discount to net asset value on the expiration date, which may be higher or lower, and the actual net asset value per share also may be higher or lower than that shown above.

(3) Excludes the aggregate liquidation preference of, and accrued and unpaid dividends with respect to, the fund's outstanding preferred shares.

(4) The net asset value per share of the fund is normally determined on each day that the New York Stock Exchange is open, as of the close of regular trading on the New York Stock Exchange, and is determined by dividing the total net assets of the fund by the number of common shares outstanding.

8. Purpose of the Offer

Purpose

The purpose of the offer is to enhance liquidity for shareholders seeking to exit the fund at a price reflecting a smaller discount to net asset value than currently available in the market.

None of the fund, its board of trustees or the investment manager makes any recommendation to any shareholder as to whether to tender or refrain from tendering any of such shareholder’s shares, and none of such persons has authorized any person to make any such recommendation. Shareholders are urged to evaluate carefully all information in this offer to purchase, consult their own investment and tax advisors and make their own decisions whether to tender shares.

Use of Securities Acquired

Shares acquired pursuant to the offer will be canceled and returned to the status of authorized but unissued equity.

Plans

In February 2007, the Board of Trustees of the fund announced that it had approved in principle a plan to merge Putnam Investment Grade Municipal Trust (NYSE ticker: PGM) and Putnam Municipal Bond Fund (NYSE ticker: PMG), both diversified, closed-end funds managed by Putnam Investments, into the fund. The merger is subject to approval by common and preferred shareholders of all three funds and certain other conditions. It is currently expected that the merger would take place in fall 2007.

12 T E N D E R O F F E R S

Except as indicated in this offer to purchase, the fund has no present plans or proposals which relate to or would result in (1) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the fund, (2) any purchase, sale or transfer of a material amount of assets of the fund, (3) any material change in the present dividend rate or policy, or indebtedness or capitalization of the fund, except that the fund’s dividend reinvestment plan may be suspended to the extent necessary for this offer, as amended, to comply with applicable law (4) any change to the fund’s present board of trustees or management, including, but not limited to, any plans or proposals to change the number or the term of trustees or to fill any existing vacancies on the board or to change any material term of the employment contract of any executive officer, (5) any other material changes in the fund’s corporate structure or business, including any plans or proposals to make any changes in its investment policy for which a vote would be required by Section 13 of the Investment Company Act of 1940, (6) any class of equity securities of the fund being delisted from a national securities exchange or ceasing to be authorized to be quoted in an automated quotations system operated by a national securities association, (7) any class or equity securities of the fund becoming eligible for termination of registration under Section 12(g)(4) of the Exchange Act, (8) the suspension of the fund’s obligation to file reports under Section 15(d) of the Exchange Act, (9) the acquisition by any person of additional securities of the fund, or the disposition of securities of the fund, or (10) any changes in the fund’s declaration of trust, bylaws or other governing instruments or other actions that could impede the acquisition of control of the fund.

The fund’s board of trustees intends to continue to review the fund’s investment performance, capitalization, management and prospects. Accordingly, the fund reserves the right to change its plans and intentions at any time, as it deems appropriate.

9. Information Concerning the Fund

The fund is a closed-end, non-diversified investment company organized as a Massachusetts business trust. The shares were first issued to the public in May 1993. As a closed-ended investment company, the fund differs from an open-end investment company in that it does not redeem its shares at the election of a shareholder and does not continuously offer its shares for sale to the public (see Section 8 of this offer to purchase). Instead the shares trade on the secondary market through their listing on the NYSE. The fund’s investment objective is to seek as high a level of current income exempt from federal income tax as Putnam Investment Management, LLC (“Putnam Management”), the fund’s manager and administrator, believes is consistent with the preservation of capital, by investing in a portfolio of investment grade and some below investment-grade municipal bonds selected by Putnam Management. The principal executive offices of the fund are located at One Post Office Square, Boston, Massachusetts 02109. The fund’s business telephone number is (617) 292-1000. On February 1, 2007, Marsh & McLennan Companies, Inc. (“MMC”) announced that it had signed a definitive agreement to sell its ownership interest in Putnam Investments Trust, the parent company of Putnam Management and its affiliates, to Great-West Lifeco Inc. Great-West Lifeco Inc. is a financial services holding company with operations in Canada, the United States and Europe and is a member of the Power Financial Corporation group of companies. Power Financial Corporation, a global company with interests in the financial services industry, is a subsidiary of Power Corporation of Canada, a financial, industrial, and communications holding company. The transaction has been approved by the respective boards of directors of MMC and Great-West Lifeco Inc., and is expected to close in 2007, subject to regulatory approval, required client consents, and other customary conditions.

The fund has various agreements with Putnam Management and its affiliates relating to advisory, custodial, administrative and investor services. The amounts paid by the fund to Putnam Management and its affiliates for these services are disclosed in the fund’s financial statements and the notes to the financial statements, which can be found in the fund’s annual and semi-annual reports.

The fund is subject to the information and reporting requirements of the Investment Company Act of 1940 and is obligated to file reports and other information with the Securities and Exchange Commission relating to its business, financial condition and other matters. The fund has also filed the Schedule TO with the Securities and Exchange Commission. Such reports and other information should be available for inspection at the public

T E N D E R O F F E R S 13

reference room at the Securities and Exchange Commission’s office, 100 F Street, N.E., Room 1580, Washington, D.C. 20549. The fund’s filings are also available to the public on the Securities and Exchange Commission’s internet site (http://www.sec.gov). Copies may be obtained, by mail, upon payment of the Securities and Exchange Commission’s customary charges, by writing to its Public Reference Section at 100 F Street, N.E., Washington, D.C. 20549.

Neither the fund nor, to the best of our knowledge, any of the fund’s officers or trustees, any person controlling the fund, or any executive officer, trustee or director of any corporation or other person ultimately in control of the fund, has effected any transaction in shares, except for dividend reinvestments, during the past 60 days.

We know of no agreement, arrangement or understanding, contingent or otherwise or whether or not legally enforceable, between (a) the fund, any of the fund’s executive officers or trustees, any person controlling the fund or any executive officer, trustee or director of any corporation or other person ultimately in control of the fund and (b) any person with respect to any securities of the fund (including any agreement, arrangement or understanding concerning the transfer or the voting of any such securities, joint ventures, loan or option arrangements, puts or calls, guarantees of loans, guarantees against loss, or the giving or withholding of proxies, consents or authorizations).

We have been advised by each of our trustees and executive officers that such individuals do not intend to tender any shares owned by them in the tender offer.

11. Legal Matters; Regulatory Approvals

Except as described in this offer to purchase, we are not aware of any license or regulatory permit that appears to be material to our business that might be adversely affected by our acquisition of shares as contemplated by the offer or of any approval or other action by any government or governmental, administrative or regulatory authority or agency, domestic or foreign, that would be required for our acquisition or ownership of shares as contemplated

14 T E N D E R O F F E R S

by the offer. Should any such approval or other action be required, we currently contemplate that we will seek approval or such other action. We cannot predict whether we may determine that we are required to delay the acceptance for payment of, or payment for, shares tendered in response to the offer, pending the outcome of any such matters. There can be no assurance that any approval or other action, if needed, would be obtained or would be obtained without substantial conditions or that the failure to obtain any approval or other action might not result in adverse consequences to our business. Our obligation to accept for payment and pay for shares under the offer is subject to various conditions. See Section 12.

12. Conditions to the Offer

Notwithstanding any other provision of the offer, the fund will not accept tenders during any period when (a) such transactions, if consummated, would (i) result in the delisting of the fund’s shares from the New York Stock Exchange or (ii) impair the fund’s status as a regulated investment company under the Code (which would make the fund a taxable entity, causing the fund’s income to be taxed at the fund level in addition to the taxation of shareholders who receive distributions from the fund); (b) there is any (i) legal or regulatory action or proceeding instituted or threatened challenging such transaction, (ii) suspension of or limitation on prices for trading securities generally on the New York Stock Exchange or other national securities exchanges, (iii) declaration of a banking moratorium by federal or state authorities or any suspension of payment by banks in the United States or New York State, (iv) limitation affecting the fund imposed by federal or state authorities on the extension of credit by lending institutions, or (v) outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the good faith judgment of the board of trustees of the fund, impractical or inadvisable to proceed with the offer; or (c) the board of trustees of the fund determines in good faith that effecting any such transaction would constitute a breach of its fiduciary duty owed to the fund or its shareholders.

The foregoing conditions are for the sole benefit of the fund and may be asserted by the fund regardless of the circumstances giving rise to any such conditions or may be waived by the fund in whole or in part at any time and from time to time in its sole discretion. The failure by the fund at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right and each such right shall be deemed an ongoing right which may be asserted at any time and from time to time. Any determination by the fund concerning the events described in this Section shall be final and binding on all parties.

A public announcement shall be made of a material change in, or waiver of, such conditions, and the offer may, in certain circumstances, be extended in connection with any such change or waiver.

If the offer is suspended or postponed, the fund will provide notice to shareholders of such suspension or postponement.

13. Fees and Expenses

Dear Investment Colleague:

I am writing to inform you that Putnam Municipal Opportunities Trust (“the fund”) has approved a tender offer program, in which the fund is making an offer to purchase up to10% of its outstanding common shares. The Putnam Trustees decided to introduce this program after considering requests from certain of its shareholders for enhanced fund liquidity and after undertaking extended discussions with Putnam Investments.

This offer is made at a price per share equal to 98% of net asset value (NAV) as of the expiration date of the offer. The offer is for up to 1,517,251 shares. These shares constitute approximately10% of the number of currently outstanding shares. Only shares properly offered to the fund (and not properly withdrawn) will be purchased. However, because of the proration provisions described in the offer to purchase, all of the shares tendered may not be purchased if more than 1,517,251 shares are properly tendered. If more shares are properly tendered, the fund will purchase all other shares properly tendered on a pro rata basis, with appropriate adjustments to avoid purchases of fractional shares. All shares tendered and not purchased, including shares not purchased because of proration, will be returned at the fund’s expense as soon as practicable following the expiration date.

For your information and for forwarding to your clients for whom you hold shares registered in your name or in the name of your nominee, we are enclosing the following documents:

• The offer to purchase, dated June 4, 2007;

• A letter that you may send to your clients for whose accounts you hold shares registered in your name or in the name of your nominee, with an Instruction Form for obtaining those clients’ direction with regard to the tender offer;

• The letter of transmittal, which is for your use and which you may make available at your discretion to your clients (the letter of transmittal also includes accompanying instructions for your use as well as a Substitute Form W-9);

• A Notice of Guaranteed Delivery. This is to be used to accept the tender offer if the share certificates and all other required documents cannot be delivered to the depositary before the expiration date or if the procedure for book-entry transfer cannot be completed before the expiration date; and

• Guidelines of the Internal Revenue Service for Certification of Taxpayer Identification Number on Substitute Form W-9.

On behalf of The Putnam Funds’ Board of Trustees, I am writing to inform you that Putnam Municipal Opportunities Trust (“the fund”) has approved a tender offer program, in which the fund is making an offer to purchase up to 10% of its outstanding common shares. The Putnam Trustees decided to introduce this program after considering requests from certain of its shareholders for enhanced fund liquidity and after undertaking extended discussions with Putnam Investments.

This offer is made at a price per share equal to 98% of net asset value (NAV) as of the expiration date of the offer. If you wish to tender your shares, you will need to do so through your financial representative. Please instruct your representative accordingly by completing the attached Instruction Form and returning it to your representative. If you do not want to tender your shares, you do not need to take any action. No changes to your account will occur as a result.

The following is a summary of several important points of the tender offer:

Specified percentage of shares. The offer is for up to 1,517,251 shares. These shares constitute approximately 10% of the number of currently outstanding shares.

Proration provision. If more shares are tendered than the fund offers to purchase, then the purchase will be made on a pro rata basis. More details on this provision can be found in the fund’s offer to purchase.

Active account required to tender shares. If for any reason your account is currently subject to a suspension of activity, you may not tender your shares until your account has been reactivated.

Trustees have a neutral view of the offer. The Trustees of the Putnam Funds have authorized the tender offer. However, the fund, its Board of Trustees, and Putnam Investment Management, LLC, do not make any recommendation as to whether to tender or not to tender shares.

In addition, these clients will have received the official offer to purchase, dated June 4, 2007, and the related letter of transmittal, which together constitute the offer, subject to any supplements and amendments. Please be advised that if your clients do not want to tender their shares, they do not need to take any action. No changes to their account will occur as a result. If, on the other hand, your clients are interested in tendering their shares, they should follow the instructions contained in the offer to purchase and the letter of transmittal.

The Board of Trustees of the fund has approved the offer. However, the fund, its Board of Trustees, and Putnam Investment Management, LLC, are not making any recommendation as to whether to tender or not to tender shares in the offer. Shareholders are urged to evaluate carefully all information in the offer to purchase and the letter of transmittal, consult their own investment and tax advisors, and make their own decisions whether to tender shares.

PUTNAM LAUNCHES TENDER OFFERS FOR EIGHT CLOSED-END FUNDS

BOSTON, June 4, 2007 – Putnam Investments today announced the launch of separate tender offers for the following closed-end funds:

Fund	Tender offer expiration date

Putnam High Income Securities Fund (NYSE: PCF)	Expires July 10, 2007

Putnam High Yield Municipal Trust (NYSE: PYM)	Expires July 9, 2007

Putnam Investment Grade Municipal Trust (NYSE: PGM)	Expires July 9, 2007

Putnam Managed Municipal Income Trust (NYSE: PMM)	Expires July 10, 2007

Putnam Master Intermediate Income Trust (NYSE: PIM)	Expires July 11, 2007

Putnam Municipal Bond Fund (NYSE: PMG)	Expires July 11, 2007

Putnam Municipal Opportunities Trust (NYSE: PMO)	Expires July 12, 2007

Putnam Premier Income Trust (NYSE: PPT)	Expires July 12, 2007

Specific documentation for each tender offer is being mailed to shareholders of the funds. As indicated above, the expiration dates for the tender offers vary.

As previously disclosed in February, each fund is offering to purchase up to 10% of its outstanding common shares for cash at a price per share equal to 98% of the net asset value per share (NAV) as of the expiration date. The tender offers are part of an effort by the Trustees of the Funds to enhance liquidity for fund shareholders.

In approving this program, the Trustees considered that tender offers would give shareholders an opportunity to sell at least some of their shares at a price close to NAV, and that the tender offer price of 98% of NAV would help offset the costs that shareholders who retain their shares would otherwise bear in connection with the tender offers.

About Putnam Investments: Founded in 1937, Putnam Investments is one of the nation's oldest and largest money management firms. As of April 30, 2007, Putnam managed $192 billion assets. Mutual fund assets were $121 billion. Institutional assets were $71 billion. Putnam has offices in Boston, London, and Tokyo. For more information, go to www.putnam.com.

Dear Investment Colleague:

On June 4, 2007 we wrote to you and your clients about the tender offer program in which eight Putnam closed-end funds are offering to purchase up to 10% of their outstanding common shares at 98% of their net asset value.

We are writing now to remind you that some of your clients who own these funds have accounts that remain subject to a suspension of activity. Should these clients wish to tender their shares, it is necessary for them to reactivate their accounts, as indicated in the tender offer materials.

We have sent a letter to each client explaining that, in order for the funds to accept tendered shares for purchase, accounts will need to be reactivated prior to the expiration date of the tender offers. It would be best to reactivate all accounts by Friday, July 6, because the tender offers expire on staggered dates between July 9 and July 12. We have also indicated that clients can contact you with questions about tendering shares or reactivating their accounts.

To reactivate these accounts, please direct your clients to call Putnam at 1-800-225-1581.

Please note that your clients are not required to tender shares, and if they prefer not to do so, they need not reactivate their accounts at this time. The Trustees of the Putnam Funds have authorized the tender offer, but the funds, the Trustees, and Putnam Investment Management, LLC do not make any recommendation as to whether to tender or not to tender shares.

If you have questions about the tender offer, please call Georgeson Inc., information agent for the tender offer, at 1-888-605-7531.

Thank you for the assistance you provide to your clients and for your support of Putnam Investments.

Respectfully yours,

Dear Shareholder:

On June 4, 2007 we wrote to you about Putnam’s tender offer program in which eight Putnam closed-end funds are offering to purchase up to 10% of their outstanding common shares at 98% of their net asset value.

We are writing now to remind you that, should you desire to tender your shares, it remains necessary for you to reactivate your Putnam account as indicated in the tender offer materials. Currently, your account remains subject to a suspension of activity. This suspension can result for several reasons, but two reasons account for the large majority of cases: the account is a joint account and one of the registered shareholders is deceased; or the fund merged with another fund, and Putnam never received the outstanding certificates of the fund that was acquired.

To speak to a Putnam representative about how to reactivate your account, call 1-800-225-1581. In order for the fund to repurchase your shares, your account will need to be reactivated prior to the expiration date of the tender offers. It would be best to reactivate all accounts by Friday, July 6, because the tender offers expire on staggered dates between July 9 and July 12.

Please note, you are not required to tender your shares, and if you prefer not to do so, you need not take steps at this time to reactivate your account. The Trustees of the Putnam Funds have authorized the tender offers, but the funds, the Trustees, and Putnam Investment Management, LLC, do not make any recommendation as to whether to tender or not to tender shares. Please note that following the tender offers the Board of Trustees will continue to monitor Putnam closed-end funds with the goal of protecting the interests of fund shareholders.

If you have any questions about the tender offers, please call Georgeson Inc., information agent for the tender offers, at 1-888-605-7531. If you have questions about whether to tender shares or to reactivate your account, you can also call your financial representative.

Thank you for your attention to this matter and for your support of Putnam Investments.

Q&A for Closed-end Fund Tender Offers

On February 15, 2007, Putnam Investments and the Board of Trustees of the Putnam Funds announced their approval of a comprehensive initiative that would (1) concentrate the lineup of closed-end funds managed by Putnam Investments through mergers combining certain funds, and (2) provide shareholders of a number of closed-end funds with enhanced liquidity opportunities either through merger into an open-end fund or through a tender offer by the fund to purchase up to 10% of the outstanding common shares.

This Q&A covers issues related to the tender offer, which are being made for eight closed-end Putnam funds.

General response to requests for additional information about the tender offer:

Shareholders will receive tender offer materials that contain complete information about the tender offer. These materials direct inquiries to Georgeson, the third party information agent for the tender offer. Georgeson has set up separate phone numbers for each of the eight funds.A list of these numbers can be found at the end of this Q&A.

What should I say if I get a call from the press?

Please direct any calls from the press to Sinead Martin in Public Relations (internal calls, x18515, external calls 617-760-8515). Public Relations will handle all communications with the news media.

Which funds are conducting a tender offer and during what period of time may shareholders tender shares?

The table below lists the funds conducting a tender offer. The tender offers commenced on June 4, 2007 and will close in July of 2007 on the dates shown in the table below, unless extended.

	Tender offer
	expiration Date
Funds conducting tender offers	(2007)

Putnam High Yield Municipal Trust (NYSE: PYM)	July 9

Putnam Investment Grade Municipal Trust (NYSE: PGM)	July 9

Putnam Managed Municipal Income Trust (NYSE: PMM)	July 10

Putnam High Income Securities Fund (NYSE: PCF)	July 10

Putnam Master Intermediate Income Trust (NYSE: PIM)	July 11

Putnam Municipal Bond Fund (NYSE: PMG)	July 11

Putnam Premier Income Trust (NYSE: PPT)	July 12

Putnam Municipal Opportunities Trust (NYSE: PMO)	July 12

How many shares will the fund repurchase?

Each fund may purchase up to 10% of its outstanding common shares. (The maximum number of shares each fund may purchase is shown in a table in Appendix 1 at the end of this Q&A.)

How much will shareholders receive for their shares?

The fund will pay cash for validly tendered shares at a price per share equal to 98% of the net asset value per share (NAV) as of the expiration date of the offer. The daily NAV of the funds can be found at Putnam’s Web site at www.putnam.com/individual/ and at Putnam’s financial representative Web site at www.putnam.com/advisor/.

Why is the tender offer price per share equal to 98% of NAV?

The Trustees considered that the difference between NAV and the tender offer price of 98% of NAV would help offset the costs that shareholders who retain their shares might otherwise bear in connection with the tender offer. In other words, the discount to NAV accepted by shareholders who tender shares serves to offset the costs to the fund that results from the tender offer.

Will any funds redeem preferred shares as a part of the tender offer?

There are no current plans for any of the funds to redeem preferred shares in connection with the tender offer.

Are shareholders required to tender their shares?

No. If you do not want to tender your shares, you do not need to take any action. No changes to your account will occur as a result.

What do shareholders need to do to if they want to tender their shares?

It is important to note that the steps for tendering shares vary based on the fund and whether the shareholder holds physical certificates for his or her shares or whether the shareholder holds shares through a brokerage account.

· Certificated shares (held directly with Putnam) — owners of these shares tender them by returning a signed letter of transmittal to Putnam indicating whether they want to tender their shares. The letter of transmittal is included with the Offer to Purchase and other tender offer materials mailed to shareholders.

· Shares held in a brokerage account — owners of these shares tender them by providing instructions to their financial representatives indicating whether they want to tender any or all of their shares.

The tender offer is being made upon the terms and subject to the conditions set forth in the offer to purchase, dated June 4, 2007, and in the related letter of transmittal.

What happens if shareholders tender more than 10% of a fund’s outstanding shares?

If more than 10% of a fund’s shares are tendered, the fund will repurchase shares on a prorated basis, meaning that the fund will repurchase an equal proportion of the shares validly tendered by each shareholder. However, if a shareholder who owns fewer than

100 shares (an “odd lot”) validly tenders all of his or her shares, the fund will repurchase all of that shareholder’s shares, without pro-ration. The shares that are not repurchased remain outstanding and shareholders continue to own them.

How will the fund communicate the results of the tender?

Each fund will issue a press release with preliminary results of the tender offer within two (2) business days following the expiration date of the tender offer, including the approximate number of shares tendered and the preliminary pro-ration results, if applicable.

When can shareholders expect to receive their money?

The fund does not expect to announce final results or send payment for any shares purchased pursuant to the offer until at least five business days after the expiration date of the tender offer (please see the table on page 1 for the expiration date of the tender offer for each fund).

Why have the Trustees approved this program of tender offers?

The Putnam Trustees decided to introduce this program after considering requests from shareholders for enhanced fund liquidity and after undertaking extended discussions with Putnam Investments. In approving this program, the Trustees considered that tender offers would give shareholders an opportunity to sell at least some of their shares at a price close to NAV.

The tender offer is part of a continuing effort by Putnam Investments and the funds’ Trustees to maintain a diverse array of closed-end products, while taking into account changing market circumstances. Putnam Investments believes that the closed-end funds continue to hold an important position in the broad range of Putnam products.

In what other ways do the Trustees pursue the interests of Putnam closed-end fund shareholders?

The Trustees meet regularly with Putnam Investments regarding the closed-end funds, and they carefully monitor the funds’ performance, the trading prices of fund shares and the expressed views of shareholders in the funds. In managing the closed-end funds, especially during periods of significant trading discounts, Putnam Investments works with the Trustees to take actions that they believe are in the long-term best interests of fund shareholders. The tender offer program is consistent with actions taken by Putnam Investments and the Trustees in recent years, including:

· Instituting a share repurchase program, under which each fund is authorized to repurchase up to 10% of its outstanding shares over a 2-year period ending in October 2007. This program enhances shareholder value, as repurchases made at a discount increase the net asset value per share of a fund’s remaining shares, and has made a meaningful contribution to investment return. Following the expiration of the tender offers, the eight funds conducting tender offers will continue to be eligible to participate in the share repurchase program. However, please note that the repurchase program has been suspended indefinitely for

Putnam New York Investment Grade Municipal Trust (AMEX: PMN) and Putnam Tax-Free Health Care Fund (NYSE: PMH) in light of the recently-announced merger proposals affecting these funds.

· Management fee reductions for most of the closed-end funds, effective January 1, 2006.

· Merging funds. In 2005, two pairs of closed-end funds merged for greater efficiencies. In 2006, a closed-end fund merged into an open-end fund managed by Putnam Investments. To date in 2007, the Trustees have approved plans to merge two additional closed-end funds into open-end funds in 2007. These last two mergers remain subject to shareholder approval.

· Promoting the funds with enhanced disclosure and providing greater transparency to investors on the merits of the closed-end funds.

· Expanding the tools available to Fund management teams, including a 2005 initiative to allow the taxable income funds to employ leverage through borrowing.
