Petitioners in the aggregate own 5,204,885 shares of common stock, which constitutes more than 25% of the outstanding shares of the respondent, and are entitled to cast more than 25% of the votes in the election of directors of the Fund. 11.As of October 9, 2008, the Funds common shares were trading at a 24.9% discount to its net asset value, and had been trading at a discount for several months prior. 12. On or about April 9, 2008, petitioner BIGP notified the Fund of its intention to submit nominations for directors and to present a proposal to convert the Fund to an open-end fund in order to eliminate the discount to net asset value for shareholder approval at the 2008 annual shareholder meeting that had not yet been scheduled. Respondent Fund refused to permit BIGP to present its nominees and proposals at the 2008 annual meeting of shareholders. 13.On April 11, 2008, the Fund announced that its 2008 annual meeting would be held on July 17, 2008. On May 13, 2008, BIGP filed a preliminary proxy statement on Schedule 14A with the Securities and Exchange Commission(the SEC) soliciting proxies from shareholders for its slate of directors and its proposal to convert the Fund to an open-end fund, which proxies were intended to be presented at the upcoming annual meeting. 14.On May 30, 2008, respondent filed with the SEC a definitive proxy statement relating to its annual meeting of shareholders scheduled to be held on July 17, 2008. Respondents filing did not include information about BIGPs proposal or nominees. 15.On June 13, 2008, BIGP filed its definitive proxy statement on Schedule 14A with the SEC. BIGP indicated that it believed that the board of directors would attempt to prevent it from presenting its nominations and its proposal for open-ending the Fund. Consequently, BIGPs proxy card included the following special instruction: THIS PROXY MAY ONLY BE USED TO ESTABLISH A QUORUM IF IT IS VOTED AS INSTRUCTED AND COUNTED. This special instruction was included in order to insure that shareholders are not disenfranchised by the board. 16.On or about June 16, 2008, BIGP sought to obtain a list of Fund shareholders from respondent. Respondent denied the request.The Fund refused to provide the list in the time legally required and in time for BIGP to use it in connection with the solicitation of proxies. Much later, the Fund granted BIGP access to its list of record stockholders, because it determined that it was required by law to do so. 17.BIGP obtained proxies from common shareholders to vote in favor of BIGPs nominees and proposal, which proxies represent more than 25 percent of the outstanding common shares of the Fund when aggregated with the BIGPs shares. Because the board had indicated that it would not permit BIGP to vote those proxies as directed, but would use the proxies to establish a quorum to allow the management slate to be elected even though a plurality of shareholders favored the BIGP candidates, BIGP did not attend the meeting in order to comply with the direction on the proxies that THIS PROXY MAY ONLY BE USED TO ESTABLISH A QUORUM IF IT IS VOTED AS INSTRUCTED AND COUNTED. 18.The July 17, 2008 annual meeting was adjourned for failure to obtain a quorum. The meeting was rescheduled for September 3, 2008, and then again for September 12,2008.Both meetings were adjourned for failure to obtain a quorum. During this period, respondent continued to solicit proxies at the shareholders expense in an attempt to obtain enough votes to reach a quorum to elect managements incumbent directors. The Fund indicated in several of its SEC filings that BIGPs nominees and proposal would not be permitted for consideration at the annual meeting.BIGP did not vote its shares or the proxies granted to it in accordance with the instructions of stockholders because management had indicated that it would not permit votes to be cast for BIGPs nominees or proposals. No directors were elected at the 2008 annual meeting. 19. BIGP believes that had it been permitted to vote its proxies in accordance with the wishes of the stockholders, a quorum would have been achieved at the annual meeting. BIGP further believes that its candidates would have received more votes than those of management. But for managements refusal to allow the proxies to be voted as directed, shareholders would have elected directors and would almost certainly have elected BIGPs candidates. Consequently, the shareholders are so divided that directors cannot be elected to the board of the Fund. 20.Petitioners,as stockholders of the Fund entitled to cast at least 25 percent of all the votes entitled to be cast in the election of directors, are entitled to the dissolution of the Fund pursuant to Maryland Corporations and Associations Code 3-413(a) on the ground that the stockholders are so divided that directors cannot be elected. WHEREFORE, petitioners demand that: A. The Court dissolve the Fund pursuant to Maryland Corporations and Associations Code 3-413(a); B. The Court award to petitioners all costs of this proceeding including, without limitation, reasonable attorneys fees and expenses of experts; and C. The Court grant such other and further relief as it may deem just, proper and equitable. Dated: October , 2008 Respectfully Submitted, TYDINGS & ROSENBERG LLP By: John B.
