SHAREHOLDER PROPOSAL

TO TERMINATE THE MANAGEMENT CONTRACT BETWEEN PUTNAM
MUNICIPAL OPPORTUNITIES TRUST AND PUTNAM INVESTMENT MANAGEMENT, LLC

Submitted by Karpus Management, Inc., d/b/a Karpus Investment Management ("Karpus")

BE IT RESOLVED
, that the Management Contract between Putnam Municipal Opportunities Trust ("PMO" or the "Fund") and Putnam Investment Management, LLC (the "Manager") shall be terminated.

SUPPORTING STATEMENT

As both common and preferred shareholders of PMO, Karpus is greatly concerned with the quality of the management of the Fund. Specifically, Karpus is most concerned with the Fund's performance as well as the "advice" the Manager has offered to the detriment of Fund shareholders and to the benefit of the Manager and the Fund's Board of Trustees.

PMO's performance has been at best mediocre across multiple time periods within its stated peer group, the Lipper General Muni Debt Leveraged category. Specifically, PMO's performance falls in the 47th percentile for one year performance, while it is below average for longer 3, 5, and 10-year periods (Source: Putnam, as of 8/31/2010). While the Fund's discount is narrow relative to its historic average, it remains wide relative to its Lipper leveraged closed-end fund category peers (Source: Lipper).

Moreover, the "advice" offered to the Board by the Manager has failed miserably. According to multiple press releases for the Fund, the Manager advised the Board of Trustees to delay a proposed merger of the Fund into an open-end fund and then ultimately advised the Board to indefinitely suspend any proposed mergers. Due to this "advice," all classes of PMO shareholders were denied the ability to realize the intrinsic value of their shares. Further, in our opinion, PMO shareholders were also misled into believing they would be able to receive net asset value for their shares and added to their positions based on the "advice" offered by our Fund's manager.

In the current market environment, many closed-end fund municipal bond shareholders have been able to receive net asset value for their common shares and par value for their preferred shares. This has not been the case with our Fund despite the fact that all four original reasons cited for merging PMO into an open-end fund are still valid to this day. Our Manager's apparent advice to our Board is to continue to lock in both common and preferred shareholders and deny them the ability to receive the intrinsic value of their shares. This is not acceptable.

PMO has been plagued by poor management long enough. To address our concerns, Karpus believes that a change is necessary and that Putnam Investment Management, LLC's management contract with PMO must be terminated.

Karpus strongly urges your support for the proposal to terminate the management contract with Putnam Investment Management, LLC.
