Vote Today for the Fund that is Delivering Monthly Distributions to You

Ahead of the Western Asset High Income Opportunity Fund Inc. (the “Fund”) Special Meeting of Shareholders on June 5, 2020, you are being asked to vote to approve new agreements¹ between the Fund and its investment manager and subadvisers that will enable the Fund to continue to operate and deliver the returns you rely on.

Why Should I Vote to Renew the Agreements with the Fund’s Investment Manager and Subadvisers?
	Approving these agreements will enable the Fund to continue to operate and deliver the returns and distributions you have come to expect from the Fund
	The investment manager and subadvisers have developed and implemented the Fund’s strategy that has enhanced shareholder value
	Importantly, the new management and subadvisory agreements will be identical to the current agreements, except for the dates of execution, effectiveness and termination

What Happens If I Don’t Vote to Approve the New Agreements?
If these new agreements are not approved, the Fund may be forced to liquidate, which could result in serious negative implications for long-term shareholders such as...
	A significant loss of shareholder value, including the discontinuation of the Fund’s distributions
	Negative tax consequences
