IF A QUORUM IS NOT PRESENT AT THE MEETING, ADDITIONAL EXPENSES WILL BE INCURRED TO SOLICIT ADDITIONAL PROXIES. TO AVOID THESE COSTS TO YOUR FUND, PLEASE VOTE, SIGN AND RETURN YOUR PROXY IN THE ENCLOSED POSTAGE-PAID ENVELOPE IMMEDIATELY. PROXY STATEMENT GENERAL INFORMATION March 15, 2000 The enclosed proxy, which was first mailed on March 15, 2000, is solicited by the Trustees for use at the Meeting. All properly executed proxies received in time for the Meeting will be voted as specified in the proxy or, if no specification is made, in favor of each proposal referred to in the Proxy Statement. The proxy may be revoked prior to its exercise by a later dated proxy, by written revocation received by the Secretary or by voting in person. Solicitation may be made by mail, telephone, telegraph, telecopy and personal interviews. Authorization to execute proxies may be obtained by telephonically or electronically transmitted instructions. The Fund will bear the cost of solicitation, which includes the printing and mailing of proxy materials and the tabulation of votes. By voting as soon as you receive your proxy materials, you will help to reduce the cost of any additional mailings. Holders of thirty percent of the shares outstanding and entitled to vote constitute a quorum and must be present in person or represented by proxy for business to be transacted at the Meeting. On February 1, 2000, the Fund had outstanding 27,645,113 Common Shares of beneficial interest and 3,600 Preferred Shares. Shareholders of record at the close of business on February 1, 2000 will have one vote for each share held. As of February 1, 2000, Cede & Co. FAST, 55 Water Street, 25th Floor, New York, New York 10041-0098, owned of record 22,034,809 Common Shares representing 80% of the Fund's outstanding Common Shares. Votes cast by proxy or in person will be counted by persons appointed by the Fund to act as election tellers for the Meeting. The tellers will count the total number of votes cast "for" approval of the proposals for purposes of determining whether sufficient affirmative votes have been cast. Where a shareholder withholds authority or abstains, or the proxy reflects a "broker non-vote" (i.e., shares held by brokers or nominees as to which (i) instructions have not been received from the beneficial owners or persons entitled to vote and (ii) the broker or nominee does not have discretionary voting power on a particular matter), the shares will be counted as present and entitled to vote for purposes of determining the presence of a quorum. Withheld authority and abstentions broker non-votes have no effect on the outcome of the voting on the items. Further information concerning the Fund is contained in its most recent Annual Report to shareholders, which is obtainable free of charge by writing the Advisor at One Financial Center, Boston, MA 02111 or by calling 1-800-426-3750. 2 The following table indicates which shareholders are solicited with respect to each matter: MATTER COMMON SHARES PREFERRED SHARES Election of four (4) Trustees by all shareholders (John V.
