The Board of Directors of the Company recommend that you vote "FOR" Proposal No. 1.

MODIFICATION OF INVESTMENT OBJECTIVE
OF THE EUROPEAN REAL ESTATE PORTFOLIO AND, AS A RESULT,
CHANGE THE INVESTMENT STRATEGY AND NAME OF THE PORTFOLIO
(Proposal No. 1)

The Portfolio's current investment objective is to provide current income and long-term capital appreciation by investing primarily in equity securities of companies in the European real estate industry. The Portfolio's investment objective is fundamental and may only be modified with shareholder approval. The Portfolio currently seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its assets in equity securities of companies in the European real estate industry. Under its current investment strategy, the Portfolio primarily invests in companies located in Germany, France, Switzerland, Belgium, Italy, Spain, Portugal, Finland, Sweden, Denmark, Norway, Ireland and the United Kingdom, but may also invest in the emerging markets of Europe.

Although the Portfolio currently may invest a portion of its assets in real estate securities outside of Europe, its fundamental investment objective limits the Portfolio to investing "primarily" in equity securities of companies in European real estate industry. Management believes that this fundamental policy unduly restricts the Portfolio from making significant investments outside of Europe. In Management's view of current global real estate markets, Management believes that it would be in the best interests of Shareholders for the Portfolio to gain more global real estate exposure. Accordingly, Management has recommended, and the Portfolio's Board of Directors has approved, submitting to Shareholders a proposal (the "Proposal") modifying the Portfolio's fundamental investment objective in order to provide it with greater flexibility to invest significantly in markets outside of Europe. If this Proposal No. 1 is approved by Shareholders, the Portfolio's investment objective would be modified to read as follows:

"to provide current income and long term capital appreciation"

If Shareholders approve the aforementioned change in the Portfolio's investment objective, Management intends to change the Portfolio's current investment strategy to one of investing, under normal circumstances, at least 80% of its assets in real estate companies in various global markets throughout the world (excluding North America). The Portfolio would primarily invest in companies located in the developed markets of Europe and Asia; the Portfolio's current fundamental policy of investing more than 25% of its total assets in the European real estate industry would remain unchanged. With these changes, the Portfolio would be permitted to invest in emerging markets located throughout the world (other than North America). Finally, to reflect the modification of the Portfolio's investment objective and the change in its investment strategy discussed above, Management intends to change the name of the Portfolio to the "International Real Estate Portfolio". Management currently intends to effect these changes in investment strategy and name within approximately one to three weeks after the required Shareholder approval has been obtained.

If this Proposal No. 1 is approved by Shareholders, the Portfolio would still be subject primarily to the risks of investing in foreign equity securities of companies in the real estate industry as currently discussed in the Portfolio's prospectus. However, the Portfolio would be able to invest a greater percentage of its assets in emerging markets due to their increased presence in the global markets outside of Europe. As discussed in the Portfolio's Prospectus, emerging markets are countries that major international financial institutions, such as the World Bank, generally consider to be less economically mature than developed nations, such as the United States or most nations in Western Europe. Emerging market countries may be more likely to experience political turmoil or rapid changes in economic conditions than more developed countries, and the financial condition of issuers in emerging market countries may be more precarious than in other countries. These characteristics result in greater risk of price volatility in emerging market countries, which may be heightened by currency fluctuations relative to the U.S. dollar.

2

At a meeting held on April 28, 2005, the Board unanimously approved the change in the Portfolio's investment objective, investment strategy and name and directed that this Proposal be submitted to Shareholders for their approval.

Vote Required and Board Recommendation

Approval of this Proposal requires the affirmative vote of the holders of a majority of the outstanding shares of the Portfolio entitled to vote thereon. The Board of Directors of the Company recommends that you vote "FOR" Proposal 1.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS

As of June 6, 2005, the following Shareholders were known by the Company to own of record and beneficially 5% or more of the Portfolio's outstanding shares:                 .

As of June 6, 2005, to the knowledge of the Adviser, the Directors and executive officers of the Company, individually and as a group, beneficially owned less than 1% of the outstanding shares of the Portfolio.

ADDITIONAL INFORMATION

General

The presence at any Shareholders' meeting, in person or by proxy, of the holders of one-third of the Portfolio's shares issued and outstanding and entitled to be cast shall be necessary and sufficient to constitute a quorum for the transaction of business. In the event that the necessary quorum to transact business or the vote required to approve the change of name, investment objective and a fundamental policy of the Portfolio is not obtained at the Meeting, the Proxies may propose one or more adjournments of the Meeting in accordance with applicable law to permit further solicitation of proxy votes. If a proxy is properly executed and returned accompanied by instructions to withhold authority to vote, represents a broker "non-vote" (that is, a proxy from a broker or nominee indicating that such person has not received instructions from the beneficial owner or other person entitled to vote Portfolio shares on a particular matter with respect to which the broker or nominee does not have a discretionary power) or is marked with an abstention (collectively, "abstentions"), the Portfolio shares represented thereby will be considered to be present at the Meeting for purposes of determining the existence of a quorum for the transaction of business. Accordingly, Shareholders are urged to forward their voting instructions promptly. Abstentions will not constitute a vote "for" or "against" a matter and will be disregarded in determining the "votes cast" on an issue.

Principal Underwriter and Administrator

Morgan Stanley Distribution, Inc., whose principal address is One Tower Bridge, 100 Front Street, West Conshohocken, Pennsylvania 19428, is the principal underwriter for the Company. JPMorgan Chase, whose principal address is 73 Tremont Street, Boston, Massachusetts 02108, serves as the Company administrator.

Submission of Shareholder Proposals

Shareholders wishing to submit proposals for inclusion in a proxy statement for a Shareholder meeting subsequent to the Meeting, if any, should send their written proposals to the Secretary of the Company at the address shown at the beginning of the Proxy Statement, within a reasonable time before the Company begins to print and mail its proxy materials for such meeting. The timely submission of a proposal does not guarantee its inclusion.

3

OTHER MATTERS

No matter other than as set forth herein is expected to come before the Meeting, but should any other matter requiring a vote of Shareholders arise, including any question as to an adjournment of the Meeting, the persons named in the enclosed Proxy Card will vote thereon according to their best judgment in the interests of the Company.

Shareholders who do not expect to be present at the meeting and who wish to have their shares voted are requested to either vote by Internet by following the instructions on the Proxy Card, or date and sign the enclosed Proxy Card and return it in the enclosed envelope. No postage is required if mailed in the United States.
