Letter to the Fund

The Putnam Funds
One Post Office Square
Boston, MA 02109

Re:	Putnam Municipal Opportunities Trust ("PMO") and
	Putnam Managed Municipal Income Trust ("PMM"), collectively the "Funds"

Mr. Horwitz:
Karpus Management, Inc., d/b/a Karpus Investment Management, represents beneficial ownership of 4,450,210 shares of PMO and 1,715,591 shares of PMM, representing 10.38% and 2.99% of each fund, respectively. On September 12, 2008, the Board of Trustees approved in principal a plan to merge PMO and PMM into open-end funds. Shareholders reacted positively, as discounts for PMO and PMM narrowed dramatically by 6.7% and 7.2%, respectively. On June 26, 2009, the Trustees reversed course and announced that the "proposed mergers in the near future would not be in the best interests of PMO and PMM's common shareholders." Further, the Trustees authorized Putnam to suspend further efforts to implement the proposed mergers.

To say the least, we are extremely disappointed that after 9 months of indecision, the Board of Trustees has ultimately decided it is not in the best interests of shareholders to submit the mergers to shareholders for approval. We wholeheartedly disagree with the Trustees' decision and feel that both preferred and common shareholders have been harmed by the Trustees' indecisiveness. Further, clearly the markets agree with our sentiment about the Trustees' poor decision to suspend further efforts to implement the proposed mergers. In fact, through July 1, just three trading days after the Funds' announcement, the discount of PMO has widened 2.96% and the discount of PMM has widened 1.54% (Source: Bloomberg).

In the Funds' original press release dated September 12, 2008, the Funds highlighted the following 4 specific benefits for shareholders if the proposed mergers were approved: (1) ability to invest in an open-end fund with similar investment objectives; (2) the elimination of the Funds' discounts; (3) ability to redeem shares at their net asset value on a daily basis; and (4) choice of timing any recognition of taxable gains or losses by the redemption of shares. Further, the Funds also acknowledged on October 30, 2008 that lowered overall expenses were expected as a result of the additional assets in connection with the mergers. All of these benefits are still applicable and desirable for shareholders today.

In addition to completely reversing course, the Funds also have not filed proxy materials for this year's annual meeting of shareholders. In our opinion, the Board could have sought the necessary shareholder approval to conduct the mergers and then implemented the mergers as they saw appropriate, with the requisite shareholder approval already in place to implement the announced mergers. However, they chose not to do so.

By not submitting the mergers to shareholders, it is our opinion that the Trustees potentially manipulated the price of both PMO and PMM by enticing shareholders to buy more shares. Further, it also appears that perhaps Putnam misled shareholders for the purpose of retaining assets under management in Funds where shareholders fully believed they would have liquidity at net asset value. Why did the Trustees not use the proxy process to let shareholders vote on the proposed mergers? After all, if the mergers were actually submitted to shareholders: (1) why would common shareholders vote against receiving net asset value for their shares; and (2) why would locked in preferred shareholders choose to not have their shares liquidated at par value?

To add insult to injury, although the Board stated "completion of these mergers is subject to a number of conditions and other factors, including shareholder approval," the Board also misdirected shareholders as to the likelihood that the mergers would, in fact, occur. To this end, the Funds stated in a press release on October 30, 2008 that they "expected" to present shareholders with a prospectus/proxy statement, stated an anticipated record date and went so far as to say that the mergers should be concluded in April 2009. Contrary to the notion that the mergers were highly likely to occur, the Funds recently stated in their April 30, 2009 annual report that they viewed the Lehman bankruptcy as the "proverbial 100-year flood" that triggered the uncertain economic conditions referenced in earlier press releases. However, 45 days after Lehman filed for bankruptcy, our Funds found it necessary to state it expected to issue a proxy, issued an anticipated record date and an anticipated closing date for the proposed mergers. Why would the Funds provide such information after the event that they say so heavily influenced their decision later to delay the proposed mergers? Further, why did the Board also state on January 9, 2009 that: "[t]he Trustees continue to believe that the proposed mergers are in the best long-term interests of shareholders and will seek to move forward with these transactions as and when market conditions permit"?

Lastly, if the Board did in fact believe that the proposed mergers were in the best interests of shareholders and was seeking to move forward with the transactions, why did our Funds act to the contrary by increasing dividends (for PMO in April and for PMM in February and, again, in June) and buying long-term municipal bonds? If the Board actually was interested in conducting the mergers, this would clearly not have been a prudent course of action. Did the Board come to a "formal" decision not to move forward with the proposed mergers before the June 26, 2009 press release?

As the events have unfolded before us, we question whether the Trustees ever really considered submitting the proposed mergers to shareholders via the Funds' proxy statements. Further, we feel that the Trustees actions and "recommendations" appear to be more driven by the Putnam Funds rather than the shareholders who they purportedly have a fiduciary duty to represent. As shareholders, we feel that we have been provided with partial, inaccurate and/or misleading information by the very individuals who have a duty to represent our interests.

Accordingly, Karpus reserves the right to exercise any and all options it has available to it as shareholders, including, but not limited to, seeking to replace the Board of Trustees, submitting a shareholder proposal, or other potential legal remedies it may deem appropriate. 
Sincerely,

/s/
