Dear Shareholder:

You are cordially invited to attend a special shareholder meeting of the State Street Research Health Sciences Fund (the “SSR Fund”), a series of the State Street Research Financial Trust, to be held on [ ], 2004. Before the meeting, I would like to provide you with additional background and ask for your vote on an important proposal affecting your fund.

As you know, the SSR Fund is advised by State Street Research & Management Company (“SSRM”). The proposal you will be asked to consider at the meeting involves the fact that SSRM’s parent company, MetLife, Inc.^®, announced on August 26, 2004 that it agreed to sell SSRM to BlackRock, Inc. (“BlackRock”), one of the largest publicly traded investment management firms in the U.S. Based in New York, BlackRock is a majority-owned, indirect subsidiary of The PNC Financial Services Group, Inc. BlackRock currently manages assets for institutional and individual investors worldwide through a variety of equity, fixed income, liquidity and alternative investment products.

The proposal you will be asked to consider at the meeting, as described in the enclosed Combined Prospectus/Proxy Statement, is the proposed reorganization (the “Reorganization”) of the SSR Fund into the BlackRock Health Sciences Portfolio (the “BlackRock Fund”), a newly created series of BlackRock Funds that will pursue identical investment objectives and similar strategies as the SSR Fund. This proposed reorganization is part of the effort to consolidate State Street Research mutual funds with comparable BlackRock mutual funds. The State Street Research and BlackRock investment management organizations have agreed to pay all expenses of the Reorganization, including proxy solicitation costs. As a result, the shareholders of the SSR Fund will not bear any costs of the Reorganization.

The Board of Trustees of the State Street Research Financial Trust believes the transaction is in the best interests of the SSR Fund and its shareholders, and unanimously recommends that you vote “FOR” the proposed reorganization.

I encourage you to carefully review the enclosed materials, which explain this proposal in more detail. As a shareholder, your vote is important, and we hope that you will respond today to ensure that your shares will be represented at the meeting. You may vote in one of the following ways:

•

By calling us toll-free at 1-87-SSR-FUNDS (1-877-773-8637);

•

By visiting our website at www.ssrfunds.com; or

•

By returning the enclosed proxy card in the postage-paid envelope.

As always, we appreciate your support.

Sincerely,

Richard S. Davis

Chairman of the Board

QUESTIONS & ANSWERS

We recommend that you read the complete Combined Prospectus/Proxy Statement. For your convenience, we have provided a brief overview of the issue to be voted on.

Q:	WHY IS A SHAREHOLDER MEETING BEING HELD?

You are being asked to approve a reorganization (the “Reorganization”) of State Street Research Health Sciences Fund (the “SSR Fund”) into BlackRock Health Sciences Portfolio (the “BlackRock Fund”), a newly created series of BlackRock Funds, that will pursue identical investment objectives and similar strategies as the SSR Fund. If the proposed Reorganization is approved and completed, an account at the BlackRock Fund will be set up in your name, you will become a shareholder of the BlackRock Fund and the SSR Fund will be dissolved, and you will have exchange privileges among the BlackRock funds. Please refer to the Combined Prospectus/Proxy Statement for a detailed explanation of the proposed Reorganization and for a more complete description of the BlackRock Health Sciences Portfolio.

The Reorganization arises out of BlackRock’s agreement, entered into on August 25, 2004, to acquire SSRM Holdings, Inc. and its subsidiary State Street Research & Management Company (“SSRM”), the investment adviser to State Street Research Health Sciences Fund, from MetLife, Inc.® (“MetLife”). As a result, the Reorganization is part of a larger initiative to consolidate the funds to which SSRM acts as investment adviser with comparable funds to which BlackRock Advisors, Inc. (“BlackRock Advisors”) serves as investment adviser.

BlackRock is one of the largest publicly traded investment management firms in the United States with approximately $[ ] billion of assets under management at September 30, 2004. BlackRock is a majority owned indirect subsidiary of The PNC Financial Services Group, Inc., one of the largest diversified financial services companies in the United States. BlackRock manages assets on behalf of institutional and individual investors worldwide through a variety of equity, fixed income, liquidity and alternative investment products.

Q:	HOW DOES THE BOARD OF TRUSTEES SUGGEST THAT I VOTE?

After careful consideration, the Board of Trustees of the SSR Fund has determined that the proposed Reorganization will benefit the shareholders of the SSR Fund and recommends that you cast your vote “FOR” the proposed Reorganization. The Board anticipates that shareholders of the SSR Fund will benefit from (i) the combined fund having access to significantly more investment professionals and related resources, (ii) the similarities between the investment objectives and policies of the BlackRock Fund and the SSR Fund, (iii) the same level of services they currently receive, including the current call center for at least one year, in addition to a broader array of options offered by a larger fund family, and (iv) the fact that BlackRock Advisors has committed to maintain the combined fund’s net operating expense ratio at a level no greater than that of the SSR Fund until February 1, 2007.

Q:	HOW WILL THE REORGANIZATION AFFECT ME?

Assuming shareholders of the SSR Fund approve the proposed Reorganization, the assets and certain stated liabilities of the SSR Fund will be combined with those of the BlackRock Fund, an account will be set up in your name at BlackRock funds and you will receive shares of the BlackRock Fund. The value of the shares you receive in the Reorganization will equal the value of the shares you own immediately prior to the Reorganization.

Q:	WHO WILL ADVISE THE BLACKROCK FUND ONCE THE REORGANIZATION IS COMPLETED?

A:	BlackRock Advisors and its portfolio managers and affiliates that run the day-to-day operation of the BlackRock funds will manage your fund.

Q:	WILL I HAVE TO PAY ANY SALES LOAD, COMMISSION OR OTHER SIMILAR FEE IN CONNECTION WITH THE REORGANIZATION?

You will pay no sales load, commission or other similar fee in connection with the Reorganization. As more fully discussed in the Combined Prospectus/Proxy Statement, the holding period with respect to any contingent deferred sales charge applicable to shares of the BlackRock Fund acquired by you in the Reorganization will be measured from the earlier of the time (i) you purchased the shares from the SSR Fund or (ii) you purchased your shares of any other State Street Research fund and subsequently exchanged them for shares of the SSR Fund.

Q:	HOW DO OPERATING EXPENSES PAID BY THE BLACKROCK FUND COMPARE TO THOSE PAYABLE BY THE SSR FUND?

Following the Reorganization, the BlackRock Fund’s contracted combined advisory, administration and 12b-1 fees will be higher than those of your fund, however, BlackRock Advisors has committed to maintain the combined fund’s net operating expense ratio at a level that is no greater than that of the SSR Fund for the year ended August 31, 2004, until February 1, 2007.

Q:	WHAT WILL I HAVE TO DO TO OPEN AN ACCOUNT IN THE BLACKROCK FUND? WHAT HAPPENS TO MY ACCOUNT IF THE REORGANIZATION IS APPROVED?

If the Reorganization is approved, an account will be set up in your name and your shares automatically will be converted into shares of the BlackRock Fund, and we will send you written confirmation that this change has taken place. You will receive the same or similar class of shares of the BlackRock Fund, except that holders of the Class B shares will receive the BlackRock Fund Investor A shares, equal in value to your shares. No certificates for shares will be issued in connection with the Reorganization. If you currently hold certificates representing your shares of the SSR Fund, it is not necessary to surrender such certificates.

Q:	WILL I HAVE TO PAY ANY FEDERAL TAXES AS A RESULT OF THE REORGANIZATION?

The Reorganization is expected to qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended. If the Reorganization so qualifies, in general, your fund will not recognize any gain or loss as a result of the transfer of all of its assets and certain stated liabilities in exchange solely for the shares of the BlackRock Fund or as a result of its liquidation, and you will not recognize any gain or loss upon your receipt solely of the shares of the BlackRock Fund in connection with the Reorganization.

Q:	WHAT IF I REDEEM OR EXCHANGE MY SHARES BEFORE THE REORGANIZATION TAKES PLACE?

If you choose to redeem or exchange your shares before the Reorganization takes place, the redemption or exchange will be treated as a normal redemption or exchange of shares and, generally, will be a taxable transaction, and, in the case of redemption, any applicable contingent deferred sales charges will be applied.

Q:	HOW DO I VOTE MY PROXY?

You may cast your vote by mail, phone or internet. To vote by mail, please mark your vote on the enclosed proxy card and sign, date and return the card in the postage-paid envelope provided. If you choose to vote via phone or internet, please refer to the instructions found on the proxy card. To vote by phone or internet, you will need the “control number” that appears on the proxy card.

Q:	WHEN WILL THE REORGANIZATION OCCUR?

A:	If approved by shareholders, the Reorganization is expected to occur in early 2005 contemporaneously with BlackRock’s acquisition of SSRM Holdings, Inc. and its subsidiary SSRM. The Reorganization will not take place in the event that for any reason BlackRock does not acquire SSRM Holdings, Inc.

Q:	WHOM DO I CONTACT FOR FURTHER INFORMATION?

A:	You can contact your financial adviser for further information. You may also call 1-87-SSR-FUNDS (1-877-773-8637) or visit our website at WWW.SSRFUNDS.COM where you can send us an e-mail message by selecting “Contact Us.”

This Combined Prospectus/Proxy Statement is furnished to you as a shareholder of State Street Research Health Sciences Fund (the “SSR Fund”). A special meeting of shareholders of the SSR Fund (the “Special Meeting”) will be held at [ ] on [ ], 2004 at [ ] p.m., Eastern time, to consider the items that are listed below and discussed in greater detail elsewhere in this Combined Prospectus/Proxy Statement. Shareholders of record of the State Street Research Health Sciences Fund at the close of business on [ ] (the “Record Date”) are entitled to notice of, and to vote at, the Special Meeting or any adjournments thereof. This Combined Prospectus/Proxy Statement, Proxy form and accompanying Notice of Special Meeting of Shareholders were first sent or given to shareholders of the SSR Fund on or about [ ]. If shareholders are unable to attend the Special Meeting or any adjournment thereof, the Board of Trustees of the State Street Research Financial Trust (the “SSR Trust”) requests that shareholders vote their shares by completing and returning the enclosed proxy card.

The purposes of the Special Meeting are:

To transact such other business as may properly be presented at the Special Meeting or any adjournment thereof.

The Board of Trustees of each of the SSR Fund and the BlackRock Fund has approved a reorganization (the “Reorganization”) by which the SSR Fund, a separate series of the SSR Trust, an open-end investment company, would be reorganized into the BlackRock Fund, an open-end investment company with an identical investment objective and similar investment policies and practices to those of the SSR Fund. The Reorganization arises out of BlackRock, Inc.’s (“BlackRock”) recent agreement, entered into on August 25, 2004, to acquire SSRM Holdings, Inc., and its subsidiary State Street Research & Management Company (“SSRM”), the investment adviser to State Street Research Health Sciences Fund, from MetLife, Inc.^® (“MetLife”). The SSR Fund and the BlackRock Fund are sometimes referred to herein each as a “Fund” and collectively as the “Funds.”

If SSR Fund shareholders approve the Reorganization, the SSR Fund will transfer all of its assets and certain stated liabilities to the BlackRock Fund. The BlackRock Fund will simultaneously issue shares to the SSR Fund in an amount equal to the net asset value of the outstanding shares of the SSR Fund. Immediately

thereafter, the SSR Fund will distribute these shares of the BlackRock Fund to its shareholders. After distributing these shares, the SSR Fund will be dissolved. When the Reorganization is complete, SSR Fund shareholders will hold shares of the BlackRock Fund. The value of the BlackRock Fund shares received in the Reorganization will equal the value of the SSR Fund shares held immediately prior to the Reorganization. After the Reorganization, the BlackRock Fund will continue to operate as a separate series of BlackRock Funds, a registered open-end investment company, with the investment objective and investment policies and practices described in this Combined Prospectus/Proxy Statement.

This Combined Prospectus/Proxy Statement sets forth concisely the information shareholders of the SSR Fund should know before voting on the Reorganization and constitutes an offering of the Investor A, B, C and Institutional shares of the BlackRock Fund only. Please read it carefully and retain it for future reference.

NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE REGULATOR HAS APPROVED OR DISAPPROVED OF THESE SHARES OR PASSED UPON THE ADEQUACY OF THIS COMBINED PROSPECTUS/PROXY STATEMENT. A REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

The date of this Combined Prospectus/Proxy Statement is [ ], 2004.

MANNER OF VOTING PROXIES

If a proxy authorization (“Proxy”) is properly given in time for a vote at the Special Meeting (either by returning the paper Proxy form or by submitting a Proxy electronically by telephone or over the Internet), the shares of the SSR Fund represented thereby will be voted at the Special Meeting in accordance with the shareholder’s instructions. The Proxy grants discretion to the persons named therein, as proxies, to take such further action as they may determine appropriate in connection with any other matter which may properly come before the Special Meeting or any adjournments thereof. The Board of Trustees of the SSR Trust does not currently know of any matter to be considered at the Special Meeting other than the matters set forth in the Notice of Special Meeting of Shareholders.

In the event that a quorum is present at the Special Meeting but sufficient votes to approve the proposed Reorganization are not received, proxies (including abstentions and broker non-votes) not directing otherwise will be voted in favor of one or more adjournments of the Special Meeting to permit further solicitation of proxies on the proposed Reorganization, provided that the Board of Trustees of the SSR Trust (the “SSR Trust Board”) determines that such an adjournment and additional solicitation is reasonable and in the interest of shareholders of the Fund based on a consideration of all relevant factors, including the nature of the particular proposals, the percentage of votes then cast, the percentage of negative votes cast, the nature of the proposed solicitation activities and the nature of the reasons for such further solicitation. Further, the persons named as proxies may propose one or more adjournments of the Special Meeting on behalf of the SSR Fund without further notice to permit further solicitation of Proxies, provided such persons determine that an adjournment and additional solicitation are reasonable and in the interest of the shareholders of the Fund, after consideration of all relevant factors, including the nature of the relevant proposal, the percentage of votes then cast, the percentage of negative votes then cast, the nature of the proposed solicitation activities and the nature of the reasons for such solicitation. Any such adjournment will require the affirmative vote of the holders of a majority of the outstanding shares voted at the session of the Special Meeting to be adjourned. A shareholder vote may be taken by the Fund on the proposal in this Combined Prospectus/Proxy Statement prior to such adjournment if sufficient votes have been received and such vote is otherwise appropriate.

For purposes of determining the presence of a quorum for transacting business at the Special Meeting and for determining whether sufficient votes have been received for approval of any proposal to be acted upon at the Special Meeting, abstentions may, in the discretion of the SSR Fund, be treated as shares which are present at the Special Meeting and entitled to vote on the matter, but which have not been voted. For this reason, abstentions could assist the SSR Fund in obtaining a quorum but would have the same effect as a vote against a proposal. The SSR Fund reserves discretion to count broker “non-votes” as present based on specific instructions from a broker or nominee. Broker “non-votes” are proxies from brokers or nominees indicating that such persons have not received instructions from the beneficial owner or other persons entitled to vote shares on a particular matter with respect to which the brokers or nominees do not have, or choose not to exercise, discretionary power.

A shareholder may vote:

by telephone (through fully automated touch-tone voting);

over the Internet;

by mail; or

in person at the Special Meeting.

BY TELEPHONE

If telephone voting is available for your account, a toll-free telephone number will be printed on your Proxy form. Prior to calling, you should read the Combined Prospectus/Proxy Statement and have your Proxy form at hand. (Please note, however, that telephone voting is not available to shareholders whose shares are held by a broker or other intermediary on the shareholder’s behalf.)

To use the automated touch-tone voting method, call the toll-free number provided on the Proxy form. At the prompt, enter the control number provided on the Proxy form, then follow the menu.

A written confirmation of your telephone instructions will be mailed within 72 hours. You should immediately call 1-87-SSR-FUNDS (1-877-773-8637) toll-free between 9 A.M. and 6 P.M. Monday through Friday Eastern time if no confirmation is received or if your instructions have not been properly reflected.

INTERNET VOTING

To vote over the Internet, please log on to WWW.SSRFUNDS.COM and click on the proxy voting button. Prior to logging on, you should read the Combined Prospectus/Proxy Statement and have your Proxy form at hand. You should enter the control number provided on the Proxy form, and follow the instructions on the screen. If you receive more than one Proxy form, you may vote them during the same session, using the relevant control numbers. (Please note, however, that internet voting is not available to shareholders whose shares are held by a broker or other intermediary on the shareholder’s behalf.)

BY MAIL

To vote by mail, you should date and sign the Proxy form included with this Combined Prospectus/Proxy Statement, indicate your vote on the proposal, and return the form in the envelope provided.

ADDITIONAL INFORMATION

SHAREHOLDERS VOTING THEIR PROXIES BY TELEPHONE OR OVER THE INTERNET SHOULD NOT RETURN THEIR PROXY FORMS BY MAIL.

A person submitting votes by telephone or over the Internet is deemed to represent that he or she is authorized to vote on behalf of all owners of the account, including spouses or other joint owners. By using the telephone or the Internet to submit voting instructions, the shareholder is authorizing [ ], a proxy solicitation firm, and its agents, to execute a proxy to vote the shareholder’s shares at the Special Meeting as the shareholder has indicated.

Any shareholder who has given a Proxy, whether by telephone, over the Internet or in written form, has the right to revoke it at any time prior to its exercise by submitting a subsequent telephone or electronic vote, or a written notice of revocation, or a later-dated Proxy, or by attending the Special Meeting and voting his or her shares in person.

The SSR Trust believes that the procedures for authorizing the execution of a Proxy by telephone or over the Internet set forth above are reasonably designed to ensure that the identity of the shareholder casting the vote is accurately determined and that the voting instructions of the shareholder are accurately recorded. [ ] and its agents will assist with the mailing and tabulation effort and may also solicit Proxies by contacting shareholders by telephone. The costs of solicitation will be borne by the State Street Research and BlackRock investment management organizations. The cost for [the solicitation agent] services is not expected to exceed $ . Brokerage firms and others will be reimbursed for their expenses in forwarding solicitation material to the beneficial owners of shares of the Funds. Representatives of State Street Research Investment Services, Inc. and other representatives of the SSR Trust may also solicit proxies. Questions about the proposal should be directed to State Street Research Investment Services, Inc. at 1-87-SSR-FUNDS (1-877-773-8637), One Financial Center, Boston, Massachusetts 02111.

SUMMARY

The following is a summary of certain information contained elsewhere in this Combined Prospectus/Proxy Statement and is qualified in its entirety by reference to the more complete information contained herein. Shareholders should read the entire Combined Prospectus/Proxy Statement carefully.

The BlackRock Fund, a newly created series of BlackRock Funds, and the SSR Fund are both series of open-end management investment companies registered with the SEC and organized as business trusts under the laws of the Commonwealth of Massachusetts. The investment objective of the SSR Fund is to seek to provide long-term growth of capital. The BlackRock Fund’s investment objective is identical to that of the SSR Fund. The SSR Fund publicly offers its shares on a continuous basis and shares may be purchased through its Fund’s distributor, State Street Research Investment Services, Inc. Following the Reorganization, the BlackRock Fund will offer its shares in a similar manner through its distributor, BlackRock Distributors, Inc. Shareholders of each Fund have the right to exchange their shares with other funds managed by the same adviser, respectively, subject to certain limitations. Additionally, each Fund permits its shareholders to redeem their shares upon proper notice.

The Proposed Reorganization

The SSR Trust Board, including the Trustees who are not “interested persons” of the SSR Fund (as defined in the 1940 Act), has unanimously approved the Reorganization Agreement. Additionally, the Board of Trustees of BlackRock Funds has unanimously approved the Reorganization Agreement. Subject to the SSR Fund shareholder approval, the Reorganization Agreement provides for:

•

the transfer of all the assets and certain stated liabilities of the SSR Fund to the BlackRock Fund in exchange for Investor A, B, C and Institutional shares of the BlackRock Fund;

•

the distribution of such shares to SSR Fund shareholders; and

•

the dissolution of the SSR Fund.

If the proposed Reorganization is completed, SSR Fund shareholders would hold shares of the BlackRock Fund with an aggregate value equal to the aggregate value of SSR Fund shares owned immediately prior to the Reorganization. SSRM is the investment adviser to the SSR Fund. BlackRock Advisors is the investment adviser to the BlackRock Fund.

Background and Reasons for the Proposed Reorganization

On August 25, 2004, BlackRock entered into an agreement with MetLife to acquire SSRM Holdings, Inc., the parent of SSRM. Under the terms of the transaction, MetLife will receive at closing $325 million in cash and $50 million of BlackRock Investor A shares. Additional cash consideration, which could increase the purchase price by up to 25%, may be paid over five years, contingent on certain measures. Closing is expected in early 2005 pending required regulatory and shareholder approvals and satisfaction of other customary closing conditions. In connection with the transaction, BlackRock and MetLife have agreed to enter into a cooperation agreement at closing to enhance and expand the products and services provided to clients of SSRM, MetLife and BlackRock. In connection with the BlackRock/SSRM transaction, it is proposed that most of the SSRM funds, including the SSR Fund, will be combined with certain BlackRock funds, subject in each case to approval by the shareholders of the relevant SSRM fund.

In approving the Reorganization Agreement, the SSR Trust Board, including its independent trustees, determined that participation in the Reorganization is in the best interests of the SSR Fund and its shareholders and that the interests of the shareholders of the SSR Fund will not be diluted as a result of the Reorganization. Before reaching these conclusions, the Board and the independent trustees engaged in a thorough review process relating to BlackRock and the proposed transactions, including the Reorganization. As part of this process, the Board held a special meeting on August 23, 2004 to meet with senior executives of BlackRock, SSRM and

MetLife to review the proposed transactions. At that meeting, the independent trustees created a subcommittee to conduct due diligence, including an examination of the proposal and the qualifications and resources of BlackRock. The activities of the subcommittee included meeting with executives and investment professionals of BlackRock and SSRM and on-site due diligence at the offices of BlackRock in New York City. Finally, on September 21 and 22, 2004 the entire Board held an additional special meeting at which the Reorganization was approved.

The factors considered by the SSR Board of Trustees with regard to the Reorganization include, but are not limited to, the following:

•

The investment objectives and policies of the SSR Fund and the BlackRock Fund are similar. (See “Comparison of the SSR Fund and the BlackRock Fund—Investment Objectives and Principal Investment Strategies.”)

•

There will be no gain or loss for shareholders’ federal income tax purposes, as the Reorganization is expected to be a tax-free transaction.

•

BlackRock has committed to maintain, until February 1, 2007, net operating expense ratios for the combined fund that are no greater than that of the SSR Fund for the year ended August 31, 2004.

•

The combined BlackRock and SSRM organizations will have significantly more investment professionals and related resources than either organization possesses individually.

•

The Board considered the composition of the investment team that will manage the combined fund, such team’s investment style and strategies (as described below under “Comparison of the SSR Fund and the BlackRock Fund—Investment Objectives and Principal Investment Strategies”), and broad information about performance, including in particular the performance record of such team since it assumed responsibility for portfolio management, and determined that such management arrangements are in the best interest of SSR Fund shareholders. (See “Management of the Funds.”)

•

Shareholders will have substantially the same services available, including the current call center, and will have access to a larger fund family with a broader array of options.

•

The costs associated with the combination of the two fund families, including the Reorganization, will be absorbed by BlackRock and SSRM and not borne by shareholders.

•

BlackRock has a strong commitment to and record of compliance.

For these and other reasons, the SSR Trust Board unanimously concluded that, based upon the factors and determinations summarized above, consummation of the Reorganization is in the best interest of the SSR Fund and its shareholders. The approval determinations were made on the basis of each Trustee’s business judgment after consideration of all of the factors taken as a whole, though individual Trustees may have placed different weight to various factors and assigned different degrees of materiality to various conclusions.

If the Reorganization does not occur, the Board will be required to consider other alternatives, such as seeking another investment adviser and administrator. If no such suitable alternatives can be found, the Board may be required to liquidate the Fund. Any such liquidation will not be tax-free for shareholders.

THE BOARD OF TRUSTEES UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE REORGANIZATION

Federal Tax Consequences

The Reorganization is expected to qualify as a tax-free “reorganization” for U.S. federal income tax purposes. If the Reorganization so qualifies, in general, neither the SSR Fund, BlackRock Fund, nor their respective shareholders, will recognize gain or loss in the transactions contemplated by the Reorganization. As a condition to the closing of the Reorganization, each of the SSR Fund and the

BlackRock Fund will receive an opinion from Skadden, Arps, Slate, Meagher & Flom LLP to that effect. No tax ruling from the Internal Revenue Service (“IRS”) regarding the Reorganization has been or will be requested. The opinion of counsel is not binding on the IRS or any court and thus does not preclude the IRS from asserting, or a court from rendering, a contrary position.

If any of the portfolio assets of the SSR Fund are sold in connection with the Reorganization, the tax impact of such sales will depend on the difference between the price at which such portfolio assets are sold and the SSR Fund’s basis in such assets. Any gains will be distributed to the SSR Fund’s shareholders as either capital-gain dividends (to the extent of long-term capital gains) or ordinary dividends (to the extent of short-term capital gains) during or with respect to the year of sale, and such distributions will be taxable to shareholders.

At any time prior to the consummation of the Reorganization, a shareholder may redeem shares, likely resulting in recognition of gain or loss to such shareholder for U.S. federal income tax purposes. For more information about the U.S. federal income tax consequences of the Reorganization, see “Material U.S. Federal Income Tax Consequences of the Reorganization.”

COMPARISON OF THE SSR FUND

AND THE BLACKROCK FUND

Investment Objectives and Principal Investment Strategies

Investment Objectives. As its investment objective, the SSR Fund seeks to provide long-term growth of capital. The BlackRock Fund’s investment objective is identical to that of the SSR Fund. The SSR Fund’s investment objective is a fundamental policy that may not be changed without shareholder approval of a majority of such Fund’s outstanding voting securities, as defined in the 1940 Act. The BlackRock Fund’s investment objective may be changed by its Board of Trustees without shareholder approval upon 30 days notice. The combined fund will pursue an investment objective identical to the SSR Fund. As a result, the proposed Reorganization is not expected to cause significant portfolio turnover or transaction expense from the sale of securities held by the SSR Fund that are incompatible with the investment objective of the combined fund. The combined portfolio will be named the BlackRock Health Sciences Portfolio.

Principal Investment Strategies. Under normal market conditions, the SSR Fund invests at least 80% of its total assets in securities of companies in health sciences and related industries. These companies include health care providers as well as businesses involved in the development, production, and distribution or delivery, of medical and pharmaceutical products and services. Companies engaged in biotechnology and medical research and development are also included, plus companies that may design, manufacture and distribute medical, dental and optical equipment and supplies, including diagnostic equipment. The companies may also provide diagnostic services or operate health facilities and hospitals, or provide related administrative, management and financial support.

In selecting investments, each Fund looks for companies that appear to have the potential for above-average growth over the long term. The SSR Fund and the BlackRock Fund invest in health care companies comparable in size to those in the health care sector of the Russell 3000^(R) Index or in similar companies, including foreign companies. The SSR Fund and the BlackRock Fund do not limit their investments to companies of any particular size. Each Funds’ investments may include common and preferred stocks, convertible securities, warrants and depository receipts.

The SSR Fund reserves the right to invest up to 20% of its total assets in other securities. These may include stocks of companies not associated with health sciences. They may also include debt securities and smaller capitalization companies.

The combined fund’s principal investment strategies will be identical to the objectives of the SSR Fund.

For information about the fundamental restrictions applicable to the SSR Fund, see Appendix A.

Principal and Other Investment Risks

Because of the similarities in investment objectives, policies and practices, the SSR Fund and the BlackRock Fund are subject to similar investment risks. The following discussion describes the principal and certain other risks that may affect the combined fund. You will find additional descriptions of specific risks in the prospectuses for the SSR Fund and the BlackRock Fund.

Each Fund’s strategy of focusing on health sciences and related companies means that its performance will be closely tied to the performance of a particular market segment. At times, the performance of these companies may lag the performance of the broader stock market.

Investments in health sciences companies are subject to a number of risks, including the adverse impact of legislative actions and government regulations. These actions and regulations can affect the approval process for patents, medical devices and drugs, the funding of research and medical care programs, and the operation and licensing of facilities and personnel. The goods and services of health sciences companies are subject to risks of rapid technological change and obsolescence, product liability litigation, and intense price and other competitive pressures.

The Funds may invest in companies that have relatively small market capitalizations. These organizations will normally have more limited product lines, markets and financial resources and will be dependent upon a more limited management group than larger capitalized companies. In addition, it is more difficult to get information on smaller companies, which tend to be less well known, have shorter operating histories, do not have significant ownership by large investors and are followed by relatively few securities analysts. The securities of smaller capitalized companies are often traded in the over-the-counter markets and may have fewer market makers and wider price spreads. This may result in greater price movements and less ability to sell the Funds’ investment than if each Fund held the securities of larger, more established companies.

Management of the Funds

BlackRock Fund. BlackRock Advisors, with its principal offices at 40 East 52^nd Street, New York, New York 10022, serves as the adviser to the BlackRock Fund and will serve as investment adviser to the combined fund after the Reorganization. BlackRock Advisors is a wholly-owned subsidiary of BlackRock, which is a majority-owned, indirect subsidiary of The PNC Financial Services Group, Inc.

SSR Fund. SSRM, with its principal offices at One Financial Center, Boston, Massachusetts 02111, serves as adviser to the SSR Fund. The firm traces its heritage back to 1924 and the founding of one of America’s first mutual funds. SSRM is responsible for the SSR Fund’s investment and business activities, and receives the management fee as compensation. SSRM is a subsidiary of MetLife.

Ajay Mehra, Managing Director, Ph.D is the lead portfolio manager of the SSR Fund and Erin Xie, senior vice president, Ph.D is a portfolio manager of the fund. Mr. Mehra has been responsible for the day-to-day management of the SSR Fund since July 2003. During the past five years he has also served as a senior vice president, vice president and portfolio manager for the Columbia Management Group. Ms. Xie has assisted with the management of the SSR Fund since 2001 and became a portfolio manager in July 2003. Ms. Xie, a senior vice president, joined SSRM in 2001. During the past five years she has also served as a research associate with Sanford Bernstein & Company.

Combined Fund. Following the Reorganization, the combined fund management team will be led by Thomas Callan, and Erin Xie, PhD. Mr. Callan has been a Managing Director at BlackRock Advisors since 1996 and served as an equity analyst for PNC Bank from 1993 to 1996.

Investment Advisory Agreements

BlackRock Fund. BlackRock Advisors renders advisory services to nearly all of the portfolios of the BlackRock funds. Various BlackRock subsidiaries provide sub-advisory services for many of the portfolios of the BlackRock funds, not including the BlackRock Fund. The investment advisory agreement with BlackRock Advisors and the other advisory and sub-advisory agreements with the BlackRock funds are collectively referred to as the “BlackRock Advisory Agreement.”

The BlackRock Advisory Agreement was approved by the BlackRock Fund’s Board of Trustees at an in-person meeting of the Board held on September 10, 2004, including a majority of the Trustees who are not parties to the agreements or interested persons of any such party (as such term is defined in the 1940 Act). In determining to approve the BlackRock Advisory Agreement, the Trustees met with the relevant investment advisory personnel from BlackRock Advisors and considered information relating to the education, experience and number of investment professionals and other personnel who would provide services under the applicable agreement. The Trustees also took into account the time and attention to be devoted by senior management to the BlackRock Fund. The Trustees evaluated the level of skill required to manage the BlackRock Fund and concluded that the human resources to be available at BlackRock Advisors were appropriate to fulfill effectively the duties of BlackRock Advisors on behalf of the BlackRock Fund under the BlackRock Advisory Agreement. The Trustees also considered the business reputation of BlackRock Advisors, its financial resources and professional liability insurance coverage and concluded that it would be able to meet any reasonably foreseeable obligations under the BlackRock Advisory Agreement.

The Trustees received information concerning the investment philosophy and investment process to be applied by BlackRock Advisors in managing the BlackRock Fund. In this connection, the Trustees considered BlackRock Advisors’ in-house research capabilities as well as other resources available to its personnel. The Trustees concluded that BlackRock Advisors’ investment process, research capabilities and philosophy were well suited to the BlackRock Fund, given the BlackRock Fund’s investment objectives, policies and practices. The Trustees considered the scope of the services provided by BlackRock Advisors to the BlackRock Fund under the BlackRock Advisory Agreement relative to services provided by third parties to other funds. The Trustees noted that the adviser’s standard of care was comparable to that found in most investment company advisory agreements. The Trustees concluded that the scope of the adviser’s services to be provided to the BlackRock Fund was consistent with the BlackRock Fund’s operational requirements, including, in addition to its investment objectives, compliance with investment restrictions, tax and reporting requirements and related shareholder services.

The Trustees considered the quality of the services to be provided by BlackRock Advisors to the BlackRock Fund. The Trustees also evaluated the procedures of BlackRock Advisors designed to fulfill its fiduciary duty to the BlackRock Fund with respect to possible conflicts of interest, including its code of ethics (regulating the personal trading of its officers and employees), the procedures by which BlackRock Advisors allocates trades among its various investment advisory clients, the integrity of the systems in place to ensure compliance with the foregoing and the record of BlackRock Advisors in these matters. The Trustees also received information concerning standards of BlackRock Advisors with respect to the execution of portfolio transactions.

In approving the BlackRock Advisory Agreement, the Trustees also gave substantial consideration to the fees payable under the agreement. The Trustees reviewed information concerning fees paid to investment advisers of similar funds. The Trustees also considered the fees of the BlackRock Fund as a percentage of assets at different asset levels and possible economies of scale to BlackRock

Advisors. In evaluating the BlackRock Fund’s advisory fees, the Trustees also took into account the complexity of investment management for the BlackRock Fund relative to other types of funds. The Trustees concluded that the fees to be paid pursuant to the BlackRock Advisory Agreement were fair and reasonable in light of the services provided, the type of portfolio and fees paid by similar funds.

BlackRock Advisors is entitled to fees computed daily and payable monthly. The maximum annual advisory fees that can be paid to BlackRock Advisors (as a percentage of average daily net assets of the fund) are as follows:

Total Annual Advisory Fee (Before Waivers)


AVERAGE DAILY NET ASSETS	INVESTMENT ADVISORY FEE
Up to $1 billion	0.750	%
$1 billion-$2 billion	0.700	%
$2 billion-$3 billion	0.675	%
more than $3 billion	0.650	%

BlackRock Advisors has agreed contractually until February 1, 2005 to waive or reimburse fees or expenses in order to limit expenses (excluding interest, taxes, brokerage commissions, and other expenditures which are capitalized in accordance with generally accepted accounting principles and other extraordinary expenses not incurred in the ordinary course of business, if any) of shares of the BlackRock Fund at the level shown in the BlackRock Fund’s expense table. The Fund may have to repay some of these waivers and reimbursements to BlackRock Advisors in the following two years. See “Current and Pro Forma Operating Expenses.”

To maintain this limit, BlackRock Advisors and the BlackRock Fund have entered into an expense limitation agreement. The agreement sets a limit on certain of the operating expenses of each class of shares through February 1, 2007 and requires BlackRock Advisors to waive or reimburse fees or expenses if these operating expenses exceed that limit. If within two years following a waiver or reimbursement the operating expenses of a share class that previously received a waiver or reimbursement from BlackRock Advisors are less than the expense limit for that share class, the share class is required to repay BlackRock Advisors up to the amount of fees waived or expenses reimbursed under the agreement if: (1) the portfolio of which the share class is a part has more than $50 million in assets, (2) BlackRock Advisors or an affiliate serves as the BlackRock Fund’s investment adviser or administrator and (3) the Board of Trustees of the BlackRock Fund has approved in advance the payments to BlackRock Advisors at the previous quarterly meeting of the Board.

The BlackRock Fund is a newly created series of BlackRock Funds, and therefore has no historical investment advisory, distribution, administrative, or other fee information.

BlackRock and PFPC Inc. (“PFPC”) serve as the BlackRock Fund’s co-administrators pursuant to an administration agreement (the “Administration Agreement”). PFPC maintains office facilities for the BlackRock Fund; furnishes the BlackRock Fund with statistical and research data, clerical, accounting, and bookkeeping services; provides and supervises the operation of an automated data processing system to process purchase and redemption orders; prepares and files certain reports required by regulatory authorities; prepares and files federal and state tax returns; prepares and files material requested by state securities regulators; calculates various contractual expenses; computes BlackRock Fund’s net asset value, net income and net capital gain or loss; and serves as a liaison with the BlackRock Fund’s independent

public accountants. Under the Administration Agreement, BlackRock is responsible for: (i) the supervision and coordination of the performance of the BlackRock Fund’s service providers; (ii) the negotiation of service contracts and arrangements between the BlackRock Fund and its service providers; (iii) acting as liaison between the trustees of the BlackRock Fund and the BlackRock Fund’s service providers; and (iv) providing ongoing business management and support services in connection with the BlackRock Fund’s operations. The Administrators may from time to time voluntarily waive administration fees with respect to the BlackRock Fund and may voluntarily reimburse the BlackRock Fund for expenses.

Under the Administration Agreement, the BlackRock funds pay to BlackRock Advisors and PFPC a fee, computed daily and payable monthly, at an aggregate annual rate of (i) 0.085% of the first $500 million of the BlackRock Fund’s average daily net assets, 0.075% of the next $500 million of the BlackRock Fund’s average daily net assets and 0.065% of the average daily net assets of the BlackRock Fund in excess of $1 billion; and (ii) 0.145% of the first $500 million of average daily net assets allocated to each class of shares of the BlackRock Fund, 0.135% of the next $500 million of such average daily net assets allocated to each class of shares and 0.125% of the average daily net assets allocated to each class of shares of the BlackRock Fund in excess of $1 billion.

SSR Fund. Prior to the Reorganization, SSRM has overall responsibility for managing the investments of the SSR Fund, subject to the authority of the Board of Trustees of the State Street Research Financial Trust. The investment advisory agreement (the “SSR Advisory Agreement”) provides that the Investment Manager will furnish the SSR Fund with an investment program and investment administrative services as may be required from time to time. Under the SSR Advisory Agreement, the Investment Manager also provides other assistance and services in connection with a number of business matters for the SSR Fund, for example the registration of the SSR Fund’s shares, subject to reimbursement of related costs. The Investment Manager compensates all personnel and Trustees if such persons are employees of the Investment Manager or its affiliates.

The SSR Advisory Agreement provides that it will continue in effect with respect to the SSR Fund for a period of two years after its initial effectiveness and will continue from year to year thereafter as long as it is approved at least annually both (i) by a vote of a majority of the outstanding voting securities of the SSR Fund (as defined in the 1940 Act) or by the Trustees of the State Street Research Financial Trust, and (ii) in either event by a vote of a majority of the Trustees who are not parties to the SSR Advisory Agreement or “interested persons” of any party thereto, cast in person at a meeting called for the purpose of voting on such approval. The SSR Advisory Agreement may be terminated on 60 days’ written notice by either party and will terminate automatically in the event of its assignment, as defined under the 1940 Act and regulations thereunder.

The advisory fee, payable monthly by the SSR Fund to SSRM, is computed as a percentage of the average of the value of the net assets of the SSR Fund as determined at the close of regular trading on the New York Stock Exchange (“NYSE”) on each day the NYSE is open for trading. The percentage rate is 0.75% of average net assets, annually.

Comparison of the Advisory Agreements

Following the Reorganization, the combined fund will be managed by BlackRock Advisors pursuant to the investment advisory agreement currently in place for the BlackRock Fund, the major elements of which are described above. The following discussion offers a summary of key similarities and differences between the BlackRock Advisory Agreement and the SSR Advisory Agreement.

As discussed above, under the BlackRock Advisory Agreement, BlackRock Advisors receives an investment advisory fee that decreases as the average daily net assets of the fund increase. Under the SSR Advisory Agreement, SSRM receives a fixed fee computed as a percentage of the average of the value of the net assets annually. Following the Reorganization, the BlackRock Fund fee structure will apply.

Both BlackRock Advisors and SSRM perform similar investment advisory roles for the Funds under the terms of their respective agreements. However, the SSR Advisory Agreement contemplates that SSRM also perform an administrative role for the SSR Fund. BlackRock Advisors performs such administrative role together with PFPC under a separate Administration Agreement, as discussed above.

Under each of the BlackRock Advisory Agreement and the SSR Advisory Agreement, BlackRock Advisors and SSRM are not liable for any error of judgment or mistake of law or for any loss suffered in connection with their respective performance obligations, to the extent such loss does not result from willful misfeasance, bad faith or gross negligence in the performance of its duties or from reckless disregard of its duties and obligations thereunder.

Each of the BlackRock Advisory Agreement and SSR Advisory Agreement is terminable as to the BlackRock Fund or SSR Fund, respectively, by vote of the board of trustees or by the holders of a majority of the outstanding voting securities of each Fund, at any time without penalty, on 60 days’ written notice to BlackRock Advisors or SSRM, as the case may be. Furthermore, BlackRock Advisors and SSRM may also terminate its advisory relationship with respect to the BlackRock Fund or SSR Fund on 60 days’ written notice. Each advisory agreement terminates automatically in the event of its assignment.

For more details on the investment advisory arrangements, see Appendix B.

Current and Pro Forma Operating Expenses

The comparative fee tables below provide information about the fees and expenses of the SSR Fund for the period ended August 31, 2004, and, assuming the Reorganization had taken place on March 31, 2004, the estimated annualized fees and expenses on a pro forma basis of the combined fund. Historical shareholder fee and operating expenses are not presented for the BlackRock Fund in the tables below since it is a newly created series of BlackRock Funds, and therefore has no historical operating history. The following tables and examples are intended to assist investors in understanding the costs and expenses that the SSR Fund shareholders bear directly or indirectly as compared to the costs and expenses that would be borne by such investors taking into account the Reorganization, assuming approval by the shareholders of the SSR Fund, each as of March 31, 2004.

BlackRock Advisors has committed through February 1, 2007 to waive fees and/or reimburse expenses to the extent necessary to maintain the combined fund’s net operating expenses at a level that is no greater than that of the SSR’s Fund’s net operating expense ratio for the year ended August 31, 2004 (the “Undertaking”).

The BlackRock Fund has a redemption fee that is imposed on certain redemptions and exchanges as set forth below. SSR Fund shares purchased prior to the Reorganization will not be subject to this fee.

Performance Information

The performance tables below illustrate the past performance of an investment in the SSR Fund. Historical performance information is not presented for the BlackRock Fund in the table below since it is a newly created series of BlackRock Funds, and therefore has no previous performance history. The SSR Fund’s past performance does not necessarily indicate how the combined fund will perform in the future. The following tables represent the average total returns for the SSR Fund. Please note that members of the team that will be part of the team that will manage the combined fund initially took on responsibility for portfolio management of the BlackRock Fund and the SSR Fund on [ ] and [ ], respectively.

The combined fund will be renamed the BlackRock Health Sciences Portfolio following the Reorganization. Because BlackRock Health Sciences Portfolio will be substantially similar to the SSR Fund, the SSR Fund will be the accounting survivor of the Reorganization. As such, the BlackRock Health Sciences Portfolio will assume the performance history of the SSR Fund at the closing of the reorganization.

Distributor

SSR Fund. State Street Research Investment Services, Inc., a division of State Street Research Services, Inc., with its principal offices at One Financial Center, Boston, Massachusetts 02111, serves as the distributor and principal underwriter for the SSR Fund. State Street Research Investment Services, Inc. is an indirect, wholly-owned subsidiary of MetLife.

BlackRock Fund. BlackRock Distributors, Inc., with its principal offices at 760 Moore Road, King of Prussia, Pennsylvania 19406, an affiliate of The PNC Financial Services Group, Inc., serves as the distributor and principal underwriter for the BlackRock Fund.

Following the Reorganization, BlackRock Distributors, Inc. will serve as the distributor of the combined fund.

Distribution and Service Fees

BlackRock Fund. The BlackRock Fund has adopted a plan (the “BlackRock Fund Distribution Plan”) that allows the BlackRock Fund to pay distribution fees for the sale of its shares under Rule 12b-1 of the 1940 Act and shareholder servicing fees for certain services provided to its shareholders.

Under the BlackRock Fund Distribution Plan holders of Investor shares pay a fee (a distribution fee) to the distributor and/or affiliates of PNC Bank Corp. (including BlackRock Advisors) for distribution and sales support services. The distribution fees may be used to pay affiliated and unaffiliated brokers, dealers, financial institutions and industry professionals (“Service Organizations”) as compensation for sales support services and related expenses. All Investor A Shares pay a maximum distribution fee of 0.10% per year of the average daily net asset value of each fund attributable to Investor A Shares. All Investor B and C Shares pay a maximum of 0.75% per year.

Under the BlackRock Fund Distribution Plan, the BlackRock Fund also pays shareholder servicing fees to Service Organizations whereby the Service Organizations provide support services to their customers who own Investor Shares in return for these fees. The BlackRock Fund may pay a shareholder servicing fee of up to 0.25% per year of the average daily net asset value of Investor shares of a fund. All Investor shares pay this shareholder servicing fee.

In return for the shareholder servicing fee, Service Organizations (including BlackRock Advisors) may provide one or more of the following services to their customers who own Investor shares:

(1)

Responding to customer questions on the services performed by the Service Organization and investments in Investor shares;

(2)

Assisting customers in choosing and changing dividend options, account designations and addresses; and

(3)

Providing other similar shareholder liaison services.

The BlackRock Fund Distribution Plan permits BlackRock Advisors, the distributor and their affiliates to make payments relating to distribution and sales support activities out of their past profits or other sources available to them (and not as an additional charge to the BlackRock Fund). BlackRock Advisors, the distributor and their affiliates may pay affiliated and unaffiliated Service Organizations compensation for the sale and distribution of shares of the BlackRock Fund or for services to the BlackRock Fund and its shareholders. These payments (“Additional Payments”) would be in addition to the payments by the BlackRock Fund and may be a fixed dollar amount, may be based on the number of customer accounts maintained by the service organization, or may be based on a percentage of the value of shares sold to, or held by, customers of the service organization.

SSR Fund. The SSR Fund has adopted plans of distribution pursuant to Rule 12b-1 under the 1940 Act (“SSR Distribution Plan”). Under the plans, shares of Classes B(1), B and C of the SSR Fund are subject to a service and distribution fee of up to 1.00% of the net assets of the SSR Fund allocable to such classes of shares. Class A is subject to a service and distribution fee of up to 0.40% of net assets allocable to such classes of shares. Currently, the annual service and distribution fees paid by Class B shares have been voluntarily waived to 0.25%. Upon completion of the Reorganization this waiver will no longer be in effect because the Class B shares will no longer be outstanding since they will be exchanged for Investor A shares of the BlackRock Fund. The distributor uses such payments for personal services and/or the maintenance of shareholder accounts, to reimburse securities dealers for distribution and marketing services, to furnish ongoing assistance to investors and to defray a portion of its distribution and marketing expenses. For Class A, Class B and Class C shares, the payments are intended to reimburse the distributor for expenditures incurred under the plan, and any unused payments are returnable to the fund. For Class B(1), the payments compensate the distributor for services and expenditures incurred under the plan, and none of the payments are returnable to the fund.

Class S shares do not have service fees.

For more information on the SSR Distribution Plan or the BlackRock Fund Distribution Plan, including a complete list of services provided thereunder, see the Reorganization SAI.

Following the Reorganization, the combined fund will use the BlackRock Fund Distribution Plan, as described above.

Purchase, Valuation, Redemption and Exchange of Shares

Procedures for the purchase, exchange and redemption of shares of the SSR Fund and the BlackRock Fund are similar. You should refer to the BlackRock Fund’s prospectus (a of which copy accompanies this Combined Prospectus/Proxy Statement) and Reorganization SAI and the SSR Fund’s Prospectus and Reorganization SAI for the specific procedures applicable to purchases, exchanges and redemptions of shares.

Purchasing Shares

BlackRock Fund. Shareholders of the BlackRock Fund may purchase shares of the BlackRock Fund through a financial intermediary or directly from the transfer agent by means of a purchase application which may be mailed to the transfer agent with a check.

Purchase orders received by the transfer agent before the close of regular trading on the New York Stock Exchange (the “NYSE”) on each day the NYSE is open will be priced based on the NAV calculated at the close of trading on that day plus any applicable sales charge. NAV is calculated separately for each class of shares of each fund as of the pricing time each day the NYSE is open.

The minimum investment for the initial purchase of Investor shares is $500. There is a $50 minimum for all later investments. The BlackRock Fund permits a lower initial investment if you are an employee of the BlackRock Fund or one of its service providers or if you participate in the Automatic Investment Plan in which you make regular, periodic investments through a savings or checking account. Institutional Shares are available to registered investment advisors for a minimum investment of $250,000 and to institutions and individuals for a minimum investment of $2 million. Such minimum investment levels will not apply to holders of the Class S shares of the SSR Fund who will receive Institutional shares as part of the Reorganization.

SSR Fund. Shareholders of the SSR Fund may purchase shares of the SSR Fund through a financial intermediary, by wire, through electronic funds transfer, through an exchange or through the Investamatic Plan. Shares in Classes A, B(1) and C are available to individuals and Class S is available to employer sponsored retirement plans and financial professionals. Class B shares are available only to individuals through reinvestment of dividends and distributions and through exchange from existing Class B accounts.

The minimum initial investments relating the shares of SSR Fund are as follows: $1,000 for accounts that use the Investamatic program, $2,000 for Individual Retirement Accounts and $2,500 for all other accounts. Thereafter, minimum additional investments are $50 for any account.

The BlackRock Fund shares and the SSR Fund shares may be purchased in a similar manner, however, the minimum initial investment for the BlackRock Fund is lower, as discussed above. Following the Reorganization, shareholders may purchase shares of the combined fund using the same procedures currently applicable to the BlackRock Fund, as described above.

Exchanging Shares

BlackRock Fund. Shareholders may exchange Investor shares of the BlackRock Fund for shares of the same class of another BlackRock Fund. Shareholders may make an exchange by sending a written request to the BlackRock Fund or telephoning the BlackRock Fund once an account is set up unless a Shareholder previously indicated that it did not want this option.

Frequent redemption or exchanges can interfere with fund management and drive up costs for all shareholders. Accordingly, the BlackRock Fund shareholders are subject to certain fees in connection with redemptions and exchanges. The redemption/exchange fee is for the benefit of the remaining shareholders of a fund and is intended to encourage long-term investment, to compensate for transaction and other expenses caused by early redemptions and exchanges, and to facilitate portfolio management. However, the redemption/exchange fee will not be assessed on redemptions or exchanges by (i) accounts managed by PNC Advisors, (ii) certain 401(k) plans, bank or trust company accounts, asset allocation programs or wrap programs approved by the BlackRock Funds, (iii) accounts of certain financial institutions or intermediaries that are unable for administrative reasons to apply the redemption/exchange fee to underlying shareholders, (iv) accounts in the event of shareholder death or disability and (v) certain other accounts in the absolute discretion of the BlackRock Funds when a shareholder can demonstrate hardship.

SSR Fund. Shareholders have the right to exchange shares among other State Street Research funds. The SSR Fund does not impose redemption/exchange fees similar to those of the BlackRock Fund. However, the SSR Fund currently limits each account, or group of accounts under common ownership or control, to six exchanges per calendar year. The SSR Fund may change or eliminate the exchange privilege at any time, may limit or cancel any shareholder’s exchange privilege and may refuse to accept any exchange request, particularly those associated with “market timing” strategies.

Following the Reorganization, you will have the right to exchange Investor A, B, or C Shares from one BlackRock fund to Investor A, B or C Shares of another BlackRock fund to meet your changing financial needs. BlackRock Funds offers 47 different funds, enough to meet virtually any investment need.

Redeeming Shares

BlackRock Fund shareholders may place redemption orders by telephoning the BlackRock Fund or by a Systematic Withdrawal Plan. Shares are redeemed at the net asset value (“NAV”) per share next determined after receipt of the redemption order, minus any applicable redemption/exchange fee, as discussed above.

The BlackRock Fund and the SSR Fund have similar policies with respect to redemption procedures and the pricing of shares, however, the BlackRock Fund charges its shareholders a fee, subject to certain exceptions, as discussed under “Exchanging Shares” above. Following the Reorganization, shareholders may redeem their shares of the combined fund using the same procedures currently applicable to the BlackRock Fund, as described in the prospectuses.

Determining Net Asset Value

BlackRock Fund. NAV is calculated separately for each class of shares of the BlackRock Fund at the close of regular trading hours on the NYSE (currently 4:00 p.m. Eastern time) on each day the NYSE is open by dividing the value of all securities, cash and other assets owned the BlackRock Fund that are allocated to a particular class of shares, less the liabilities charged to that class, by the total number of outstanding shares of the class.

Valuation of securities is as follows: securities traded on a national securities exchange or on the NASDAQ National Market System are valued at the last reported sale price that day or the NASDAQ official closing price, if applicable; securities traded on a national securities exchange for which there were no sales on that day and securities traded on other over-the-counter markets for which market quotations are readily available are valued at the mean of the bid and asked prices; an option or futures contract is valued at the last sales price prior to 4:00 p.m. (Eastern time), as quoted on the principal exchange or board of trade on which such option or contract is traded, or in the absence of a sale, the mean between the last bid and asked prices prior to 4:00 p.m. (Eastern time); and securities for which market quotations are not readily available are valued at fair market value as determined in good faith by or under the direction of the BlackRock Trust’s Board of Trustees.

SSR Fund. The SSR Fund calculates its NAV in a manner substantially similar to the BlackRock Fund.

Following the Reorganization, NAV will determined in a manner consistent with the BlackRock Fund’s procedures, as described above.

Other Service Providers

BlackRock Fund. PFPC, with its principal office at 301 Bellevue Parkway, Wilmington, Delaware 19809, and BlackRock Advisors, with its principal offices at 40 East 52nd Street, New York, New York 10022, serves as co-administrators to the BlackRock Fund. PFPC also serves as the transfer agent and dividend disbursing agent for the BlackRock Fund. PFPC Trust Company, whose principal offices are located at 8800 Tinicum Boulevard, Philadelphia, Pennsylvania 19153, serves as the BlackRock Fund’s custodian. PFPC and BlackRock are both affiliates of The PNC Financial Services Group, Inc. Deloitte & Touche LLP, with its offices at 1700 Market Street, 24^th Floor, Philadelphia, Pennsylvania 19103-3984, is the independent registered public accounting firm for the BlackRock Fund.

SSR Fund. State Street Bank and Trust Company, located at 225 Franklin Street, Boston, Massachusetts 02110, serves as the transfer agent and custodian for the SSR Fund. Deloitte & Touche LLP, with its offices at 200 Berkeley Street, Boston, Massachusetts 02116, is the independent registered public accounting firm for the SSR Fund.

COMPARATIVE INFORMATION ON SHAREHOLDER

RIGHTS AND OBLIGATIONS

While SSR Fund and BlackRock Fund are series of different entities and, thus, governed by different organizational documents, the Reorganization will not result in material differences in shareholder rights. The shares of the BlackRock Fund to be distributed to shareholders of the corresponding SSR Fund will generally have the same legal characteristics as the shares of the SSR Fund with respect to such matters as voting rights, accessibility, and transferability.

The SSR Fund and the BlackRock Fund are each separate series of two different companies organized as Massachusetts business trusts and governed by their separate Declarations of Trust. Under their Declarations of Trust, the BlackRock Fund and the SSR Fund are each authorized to issue an unlimited number of shares of beneficial interest with a par value of $0.001 per share. The Boards of the

trusts of which the SSR Fund and BlackRock Fund are series may, without limitation, classify or reclassify any unissued shares of the SSR Fund or the BlackRock Fund into any number of additional classes of shares. The Boards of the two trusts may also, without limitation, classify or reclassify any unissued shares into one or more additional series, each with its own assets and liabilities. The BlackRock Fund offers five classes of shares (designated as Investor A, B, C, Service and Institutional Shares). The SSR Fund offers five classes of shares (designated Class A, B, B(1), C and S).

Each of the SSR Fund and the BlackRock Fund will continue indefinitely until terminated.

With respect to each series of shares of the two trusts, shares of the same class within such series have equal dividend, distribution, liquidation, and voting rights, and fractional shares have those rights proportionately. Each series and class of shares within such series of the two trusts bears its own expenses related to its distribution of shares (and other expenses such as shareholder or administrative services).

Unless (i) the Trustees have determined that a matter only affects the interests of one or more class or classes (in which case only shareholders of the affected class or classes are entitled to vote), (ii) required by applicable law, or (iii) permitted by the Board of Trustees, all shares entitled to vote on any matter submitted to a vote of any series or class of shareholders of the BlackRock Fund are voted in the aggregate and not by class. However, unless (i) voting for Trustees, (ii) otherwise required by the 1940 Act, or (iii) with respect to matters that do not affect the interests of such class, all shares of the SSR Fund and classes thereof will vote as a separate class.

There are no preemptive rights in connection with shares of either trust. When issued in accordance with the provisions of their respective prospectuses (and, in the case of shares of the BlackRock Fund issued in the provisions of the Reorganization Plan), all shares are fully paid and non-assessable.

THE FOREGOING IS ONLY A SUMMARY OF CERTAIN RIGHTS OF SHAREHOLDERS UNDER THE CHARTER DOCUMENTS GOVERNING THE SSR FUND AND THE BLACKROCK FUND AND APPLICABLE STATE LAW, AND IS NOT A COMPLETE DESCRIPTION OF PROVISIONS CONTAINED IN THOSE SOURCES. SHAREHOLDERS SHOULD REFER TO THE PROVISIONS OF THOSE DOCUMENTS AND STATE LAW DIRECTLY FOR A MORE THOROUGH DESCRIPTION.

FINANCIAL HIGHLIGHTS

The fiscal year end of the BlackRock Fund is September 30. There are no financial highlights for the BlackRock Fund as it has not yet commenced operations. The independent registered public accounting firm for the BlackRock Fund is Deloitte & Touche LLP, Berkeley Street, Boston, Massachusetts 02116.

INFORMATION ABOUT THE REORGANIZATION

General

Under the Reorganization Agreement, the SSR Fund will transfer all of its assets and certain stated liabilities to the BlackRock Fund in exchange for Investor A, B, C and Institutional shares of the BlackRock Fund. For more details about the Reorganization Agreement, see Appendix C “Form of Agreement and Plan of Reorganization.” The shares of the BlackRock Fund issued to the SSR Fund will have an aggregate value equal to the aggregate value of the SSR Fund shares immediately prior to the Reorganization. Upon receipt by the SSR Fund of the shares of the BlackRock Fund, the SSR Fund will distribute the shares to SSR Fund shareholders. Then, as soon as practicable after the Closing Date (as defined in Appendix C), the SSR Fund will be dissolved under applicable state law.

Such distribution will be accomplished by opening new accounts on the books of the BlackRock Fund in the names of the SSR Fund shareholders and transferring to those shareholder accounts the shares of the BlackRock Fund previously credited on those books to the accounts of the SSR Fund shareholders. Each newly-opened account on the books of the BlackRock Fund for the previous SSR Fund shareholders will represent the respective pro rata number of shares of the same or similar class of the BlackRock Fund, except that holders of the Class B shares will receive the BlackRock Fund Investor A shares.

Accordingly, as a result of the Reorganization, each SSR Fund shareholder will own the same or similar class of shares of the BlackRock Fund, except that holders of the Class B shares will receive the BlackRock Fund Investor A shares, having an aggregate value immediately after the Closing Date equal to the aggregate value of that shareholder’s SSR Fund shares immediately prior to the Closing Date. The Reorganization will not result in dilution of either Fund’s shares. However, as a result of the Reorganization, a shareholder of either of the SSR Fund or the BlackRock Fund will hold a reduced percentage of ownership in the larger combined fund than the shareholder did in either of the separate Funds.

No sales charge or fee of any kind will be assessed to the SSR Fund shareholders in connection with their receipt of shares of the BlackRock Fund in the Reorganization.

Terms of the Agreement

Pursuant to the Reorganization Agreement, the BlackRock Fund will acquire all of the assets and certain stated liabilities of the SSR Fund on the Closing Date in consideration for shares of the BlackRock Fund.

On the Closing Date, the SSR Fund will transfer to the BlackRock Fund all of its assets in exchange solely for Investor A, B, C and Institutional shares of the BlackRock Fund that are equal in value to the value of the net assets of the SSR Fund transferred to the BlackRock Fund as of the Closing Date, as determined in accordance with BlackRock Fund’s valuation procedures or such other valuation procedures as shall be mutually agreed upon by the parties, and the assumption by the BlackRock Fund of all of the liabilities of the SSR Fund provided for in an agreed upon schedule prior to the Closing Date. In order to minimize any potential for undesirable federal income and excise tax consequences in connection with the Reorganization, the SSR Fund will distribute on or before the Closing Date all of its undistributed net investment income (including net capital gains) as of such date.

The SSR Fund expects to distribute the shares of the BlackRock Fund to the shareholders of the SSR Fund promptly after the Closing Date and then dissolve pursuant to a plan of dissolution adopted by the Board and terminate its registration under the 1940 Act.

The trusts of which the BlackRock Fund and the SSR Fund are series have made certain standard representations and warranties to each other regarding capitalization, status and conduct of business.

Unless waived in accordance with the Agreement, the obligations of the parties to the Agreement are conditioned upon, among other things:

•

the approval of the Reorganization by the SSR Fund’s shareholders;

•

the completion of the acquisition of SSRM’s parent company by BlackRock;

•

the absence of any rule, regulation, order, injunction or proceeding preventing or seeking to prevent the consummation of the transactions contemplated by the Agreement;

•

the receipt of all necessary approvals, consents, registrations and exemptions under federal, state and local laws;

•

the truth in all material respects as of the Closing Date of the representations and warranties of the parties and performance and compliance in all material respects with the parties’ agreements, obligations and covenants required by the Agreement;

•

the effectiveness under applicable law of the registration statement of the BlackRock Fund of which this Combined Prospectus/Proxy Statement forms a part and the absence of any stop orders under the Securities Act of 1933, pertaining thereto;

•

the declaration of a dividend by SSR Fund to distribute all its undistributed net investment income and net capital gains; and

•

the receipt of opinions of counsel relating to, among other things, the tax free nature of the Reorganization.

The Agreement may be terminated or amended by the mutual consent of the parties either before or after approval thereof by the shareholders of the SSR Fund.

The SSR Trust Board recommends that you vote to approve the Reorganization, as it believes the Reorganization is in the best interests of the SSR Fund’s shareholders (as described more fully in “The Proposed Reorganization—Reasons for the Proposed Reorganization”) and that the interests of the SSR Fund’s existing shareholders will not be diluted as a result of consummation of the proposed Reorganization.

Reasons for the Reorganization

The factors considered by the SSR Board of Trustees with regard to the Reorganization include, but are not limited to, the following:

•

The investment objectives and policies of the SSR Fund and the BlackRock Fund are similar. (See “Comparison of the SSR Fund and the BlackRock Fund — Investment Objectives and Principal Investment Strategies.”)

Through the Reorganization, shareholders will be invested in a fund with substantially similar objectives and strategies. As a result, the style and risk/return profile of the surviving fund will remain comparable to that of the shareholders’ current investment. In addition, the Reorganization is not expected to cause significant portfolio turnover or transaction expenses from the sale of securities that are incompatible with the objective of the surviving fund.

•

There will be no gain or loss for shareholders’ federal income tax purposes, as the Reorganization is expected to be a tax-free transaction.

The Reorganization provides for a tax-free exchange of shares resulting in the assets and certain stated liabilities of the SSR Fund being assumed by the reorganized BlackRock Fund. Shareholders will receive BlackRock Fund shares equivalent to the value of their SSR Fund shares, and will pay no federal income tax on the transaction.

•

BlackRock has committed to maintain, until February 1, 2007, net operating expenses for the combined fund that are no greater than those paid by the SSR Fund for the year ended August 31, 2004.

In most cases, the surviving BlackRock fund has a lower expense ratio than the current SSR Fund. When this is not the case, BlackRock has agreed to subsidize expenses in order for expense ratios to remain in line with the current SSR Fund. This subsidy will continue for 2 years, after which expense ratios will be consistent with the BlackRock Fund pricing – which is set consistent with industry norms and competitive considerations.

•

The combined BlackRock and SSRM organization will have significantly more investment professionals and related resources than either organization possesses individually.

The combination of the BlackRock and SSRM organizations will enhance the combined organization’s market position and influence in the industry. The resulting organization will manage diverse products across multiple asset classes and styles, allowing shareholders access to a wider segment of the market than either organization currently possesses on its own.

•

As described above under “Comparison of the SSR Fund and the BlackRock Fund – Investment Objectives and Principal Investment Strategies” and “Management of the Funds,” the team that manages the SSR Fund, which takes an “active fundamental” investment approach, will merge with a team of BlackRock investment professionals, which also takes an “active fundamental” investment approach. In determining that this combination of investment teams is in the best interests of SSR Fund shareholders, the Board carefully considered the composition of the combined team, its retention of the “active fundamental” investment approach, and broad information about performance, including in particular the performance record of the team that manages the SSR Fund since it assumed responsibility for portfolio management of the SSR Fund. (See “Management of the Funds”).

•

Shareholders will have substantially the same services available, including, for at least one year, the current call center, and will have access to a larger fund family with a broader array of options.

Shareholders will have access to the customer service that they currently have access to through the State Street Research call center, which will be maintained for at least one year. Specific service features – such as minimum investments, exchange rules, and automated investing plans – will remain consistent or become more favorable. The combined firm will offer an expanded product offering: currently, SSRM manages 14 open-end mutual funds with over $9 billion in assets, while BlackRock Advisors manage $17 billion across 42 open-end mutual funds. This broader product offering offers shareholders greater opportunity to diversify assets by exercising the exchange privilege between funds in the family.

•

The costs associated with combination of the two fund families, including the Reorganization, will be absorbed by BlackRock and SSRM and not borne by shareholders.

Shareholders will not bear any costs associated with the Reorganization, including proxy solicitation expenses and sales charges. Proxy solicitation expenses include legal fees, printing, packaging and postage – all of which will be covered by the State Street Research and BlackRock organizations. Shareholders will not have to pay any sales charge on the BlackRock fund shares they receive in the reorganization, nor will they be charged any contingent deferred sales charge (“CDSC”) on the exchange of their SSR Fund shares. For purposes of determining the application of any CDSC, the holding period for their SSR Fund shares will carry over to the BlackRock Fund shares they receive in the Reorganization.

•

BlackRock has a strong commitment to, and record, of compliance.

Shareholders will benefit from BlackRock’s strong compliance culture, which includes: a company-wide compliance education program; dedicated legal and compliance personnel for areas throughout the organization; frequent communication to fund boards; committed outside firms to handle fund and regulatory counsel as well as counsel to independent trustees. In addition, BlackRock has advised the Board that it has no significant regulatory matters pending.

Material U.S. Federal Income Tax Consequences of the Reorganization

The following is a general summary of the material anticipated U.S. federal income tax consequences of the Reorganization. The discussion is based upon the Internal Revenue Code of 1986, as amended (the “Code”), Treasury regulations, court decisions, published positions of the IRS and other applicable authorities, all as in effect on the date hereof and all of which are subject to change or differing interpretations (possibly with retroactive effect). The discussion is limited to U.S. persons who hold shares of the SSR Fund as capital assets for U.S. federal income tax purposes. This summary does not address all of the U.S. federal income tax consequences that may be relevant to a particular shareholder or to shareholders who may be subject to special treatment under federal income tax laws. No ruling has been or will be obtained from the IRS regarding any matter relating to the Reorganization. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of the tax aspects described below. Shareholders must consult their own tax advisers as to the U.S. federal income tax consequences of the Reorganization, as well as the effects of state, local and non-U.S. tax laws.

It is a condition to closing the Reorganization that each of the SSR Fund and the BlackRock Fund receives an opinion from Skadden, Arps, Slate, Meagher & Flom LLP, special counsel to the BlackRock Fund, dated as of the Closing Date, that the Reorganization will be a “reorganization” within the meaning of Section 368(a) of the Code and that the BlackRock Fund and the SSR Fund each will be a “party to a reorganization” within the meaning of Section 368(b) of the Code. As such a reorganization, the federal income tax consequences of the Reorganization can be summarized as follows:

•

No gain or loss will be recognized by the SSR Fund or the BlackRock Fund upon the transfer all of the assets of the SSR Fund to the BlackRock Fund solely in exchange for the shares of the BlackRock Fund and the assumption by the BlackRock Fund of the liabilities of the SSR Fund, or upon the distribution of the shares of the BlackRock Fund by the SSR Fund to its shareholders in the subsequent liquidation of the SSR Fund.

•

No gain or loss will be recognized by a shareholder of the SSR Fund who exchanges all of his, her or its shares of the SSR Fund solely for the shares of the BlackRock Fund pursuant to the Reorganization.

•

The aggregate tax basis of the shares of the BlackRock Fund received by a shareholder of the SSR Fund pursuant to the Reorganization will be the same as the aggregate tax basis of the shares of the SSR Fund surrendered in exchange therefor.

•

The holding period of the shares of the BlackRock Fund received by a shareholder of the SSR Fund pursuant to the Reorganization will include the holding period of the shares of the SSR Fund surrendered in exchange therefor.

•

The BlackRock Fund’s tax basis in the SSR Fund’s assets received by the BlackRock Fund pursuant to the Reorganization will, in each instance, equal the tax basis of such assets in the hands of the SSR Fund immediately prior to the Reorganization, and the BlackRock Fund’s holding period of such assets will, in each instance, include the period during which the assets were held by the SSR Fund.

•

The holding period of the assets of the SSR Fund in the hands of the BlackRock Fund will include the period during which those assets were held by the SSR Fund.

The opinion of Skadden, Arps, Slate, Meagher & Flom LLP will be based on U.S. federal income tax law in effect on the Closing Date. In rendering its opinion, Skadden, Arps, Slate, Meagher & Flom LLP will also rely upon certain representations of the management of the BlackRock Fund and the SSR Fund and assume, among other things, that the Reorganization will be consummated in accordance with the operative documents. An opinion of counsel is not binding on the IRS or any court.

The BlackRock Fund intends to be taxed under the rules applicable to regulated investment companies as defined in Section 851 of the Code, which are the same rules currently applicable to the SSR Fund and its shareholders.

A portion of the portfolio assets of the SSR Fund may be sold in connection with the Reorganization. The tax impact of such sales will depend on the difference between the price at which such portfolio assets are sold and the SSR Fund’s basis in such assets. Any capital gains recognized in these sales on a net basis will be distributed to the SSR Fund’s shareholders as capital-gain dividends (to the extent of net realized long-term capital gains) and/or ordinary dividends (to the extent of net realized short-term capital gains) during or with respect to the year of sale, and such distributions will be taxable to shareholders.

As noted above, shareholders of the SSR Fund may redeem their shares or exchange their shares for shares of certain other funds distributed by the distributor at any time prior to the closing of the Reorganization. See “Purchase, Valuation, Redemption and Exchange of Shares” above. Redemptions and exchanges of shares generally are taxable transactions, unless your account is not subject to taxation, such as an individual retirement account or other tax-qualified retirement plan. Shareholders should consult with their own tax advisers regarding potential transactions.

Expenses of the Reorganization

BlackRock, BlackRock Advisors’ parent company, and SSRM Holdings, Inc., SSRM’s parent company, will equally share in the expenses incurred in connection with the Reorganization and preparation of this Combined Prospectus/Proxy Statement, including all direct and indirect expenses and out-of-pocket costs.

Expenses incurred in connection with the Reorganization include, but are not limited to: all costs related to the preparation and distribution of materials distributed to each Fund’s Board including legal and accounting costs; all expenses incurred in connection with the preparation of the Reorganization Agreement and a registration statement on Form N-14; SEC and state securities commission filing fees and legal and audit fees in connection with the Reorganization; the costs of printing and distributing this Combined Prospectus/Proxy Statement; auditing fees associated with each Fund’s financial statements; portfolio transfer taxes (if any); and any similar expenses incurred in connection with the Reorganization. Neither the Funds nor SSRM or BlackRock Advisors will pay any expenses of shareholders arising out of or in connection with the Reorganization.

All other expenses of each of the parties shall be paid by the applicable party.

Continuation of Shareholder Accounts and Plans; Share Certificates

If the Reorganization is approved, the BlackRock Fund will establish an account for each SSR Fund shareholder containing the appropriate number of shares of the BlackRock Fund. Shareholders of the SSR Fund who are accumulating SSR Fund shares under the dividend reinvestment plan, who are receiving payment under the systematic withdrawal plan, or who benefit from special sales programs with respect to SSR Fund shares, will retain the same rights and privileges after the Reorganization in connection with the shares of the BlackRock Fund received in the Reorganization through similar plans maintained by the BlackRock Fund.

It will not be necessary for shareholders of the SSR Fund to whom certificates have been issued to surrender their certificates. Upon dissolution of the SSR Fund, such certificates will become null and void. Generally, no certificates for the BlackRock Fund will be issued.

Legal Matters

Certain legal matters concerning the federal income tax consequences of the Reorganization and issuance of shares of the BlackRock Fund will be passed on by Skadden, Arps, Slate, Meagher & Flom LLP, which serves as special counsel to the BlackRock Fund.

Shareholder Proposals

The Funds do not hold regular annual meetings of shareholders. As a general matter, the BlackRock Fund does not intend to hold future regular annual or special meetings of its shareholders unless required by the 1940 Act. In the event the Reorganization is not completed, the SSR Fund does not intend to hold future regular annual or special meetings of its shareholders unless required by the 1940 Act. Any shareholder who wishes to submit proposals for consideration at a meeting of shareholders of the SSR Fund or the BlackRock Fund should send such proposal to the respective Fund at [ ]. To be considered for presentation at a shareholders’ meeting, rules promulgated by the SEC require that, among other things, a shareholder’s proposal must be received at the offices of the Fund a reasonable time before a solicitation is made. Timely submission of a proposal does not necessarily mean that such proposal will be included.

Solicitation of Proxies

Solicitation of proxies is being made primarily by the mailing of this Notice and Combined Prospectus/Proxy Statement with its enclosures on or about [ ], 2004. SSR Fund shareholders whose shares are held by nominees such as brokers can vote their proxies by contacting their respective nominee. In addition to the solicitation of proxies by mail, employees of [ ] and its affiliate as well as dealers or their representatives may, without additional compensation, solicit proxies in person or by mail, telephone, facsimile or oral communication. The SSR Fund has retained [ ], a professional proxy solicitation firm, to assist with any necessary solicitation of proxies. SSR Fund shareholders may receive a telephone call from a professional proxy solicitation firm asking them to vote. The proxy solicitation expenses for the proposed Reorganization are estimated to be approximately $[ ], all of which will be borne by BlackRock and SSRM.

VOTING INFORMATION AND REQUIREMENTS

Approval by the SSR Fund of the proposed Reorganization will require the affirmative vote of the holders of a majority of the outstanding shares entitled to vote, as defined under the 1940 Act. The 1940 Act defines such vote as the lesser of (i) 67% or more of the total number of shares of all classes of the Fund present or represented by proxy at the Special Meeting, voting together as a single class, if holders of more than 50% of the outstanding shares of all classes, taken as a single class, are present or represented by proxy at the Special Meeting; or (ii) more than 50% of the total number of outstanding shares of all classes of such Fund, voting together as a single class. The holders of a majority of the shares of the SSR Fund entitled to vote shall be a quorum for the Special Meeting. If the shareholders fail to approve the proposed Reorganization, the Reorganization will not occur. If the shareholders fail to approve the proposed Reorganization, the Reorganization will not occur. The SSR Trust Board has fixed the close of business on [ ], 2004 as the Record Date for the determination of shareholders entitled to notice of, and to vote at, the Special Meeting. SSR Fund shareholders on the Record Date are entitled to one vote for each share held, with no shares having cumulative voting rights.

SSR Fund shareholders may vote by appearing in person at the Special Meeting, by returning the enclosed proxy card or by casting their vote via telephone or the internet using the instructions provided on the enclosed proxy card. Any person giving a proxy may revoke it at any time prior to its exercise by executing a superseding proxy, by giving written notice of the revocation to the secretary of the SSR Fund or by voting in person at the Special Meeting.

All properly executed proxies received prior to the Special Meeting will be voted in accordance with the instructions marked thereon or otherwise as provided therein. Unless instructions to the contrary are marked, proxies will be voted “FOR” the approval of the proposed Reorganization. Abstentions and broker non-votes (i.e., where a nominee such as a broker holding shares for beneficial owners votes on certain matters pursuant to discretionary authority or instructions from beneficial owners, but with respect to one or more proposals does not receive instructions from beneficial owners or does not exercise discretionary authority) may in certain circumstances have the same effect as votes “AGAINST” the Reorganization since approval of the proposal could in some circumstances require the affirmative vote of a majority of the total shares outstanding. A majority of the outstanding shares entitled to vote on a proposal must be present in person or by proxy to have a quorum to conduct business at the Special Meeting.

Shareholders who execute proxies may revoke them at any time before they are voted by filing with the SSR Fund a written notice of revocation, by delivering a duly executed proxy bearing a later date or by attending the Special Meeting and voting in person. The giving of a proxy will not affect your right to vote in person if you attend the Special Meeting and wish to do so.

The SSR Trust Board knows of no business other than that described in the Notice which will be presented for consideration at the Special Meeting. If any other matters are properly presented, it is the intention of the persons named on the enclosed proxy card to vote their proxies in accordance with their best judgment.

If you cannot be present in person at the meeting, you are requested to fill in, sign and return the enclosed proxy card promptly. No postage is necessary if mailed in the United States.

THIS AGREEMENT AND PLAN OF REORGANIZATION (the “Agreement”) is made as of this [ ] day of [ ], 2004, by and among BlackRock Funds^SM, a registered investment company and a Massachusetts business trust (the “Acquiring Trust”), with respect to BlackRock Health Sciences Portfolio, a separate series of the Acquiring Trust (the “BlackRock Fund”), and State Street Research Financial Trust, a registered investment company and a Massachusetts business trust (the “Selling Trust”), with respect to State Street Research Health Sciences Fund, a separate series of the Selling Trust (the “SSR Fund”).

This Agreement is intended to be, and is adopted as, a plan of reorganization within the meaning of Section 368(a) of the United States Internal Revenue Code of 1986, as amended (the “Code”), and the Treasury Regulations promulgated thereunder. The reorganization will consist of: (i) the transfer of all of the assets of the SSR Fund in exchange for Investor A, B, C and Institutional shares of the BlackRock Fund (“BlackRock Fund Shares”); (ii) the assumption by the Acquiring Trust, on behalf of the BlackRock Fund, of the Stated Liabilities (as defined in paragraph 1.3) of the SSR Fund; and (iii) the distribution, after the Closing Date (as defined in paragraph 3.1), of the BlackRock Fund Shares to the shareholders of the SSR Fund and the termination, dissolution and complete liquidation of the SSR Fund, all upon the terms and conditions set forth in this Agreement (the “Reorganization”).

WHEREAS, the BlackRock Fund is a separate series of the Acquiring Trust, and the SSR Fund is a separate series of the Selling Trust; the Acquiring Trust and the Selling Trust are open-end, registered management investment companies within the meaning of the Investment Company Act of 1940 (the “1940 Act”), and the SSR Fund owns securities that generally are assets of the character in which the BlackRock Fund is permitted to invest;

WHEREAS, each of the BlackRock Fund and the SSR Fund is properly treated as a “regulated investment company” under Subchapter M of the Code;

WHEREAS, the BlackRock Fund is authorized to issue its shares of beneficial interest;

WHEREAS, the Board of Trustees of the Acquiring Trust has determined that the Reorganization is in the best interests of the BlackRock Fund and that the interests of the existing shareholders of the BlackRock Fund will not be diluted as a result of the Reorganization;

WHEREAS, the Board of Trustees of the Selling Trust has determined that the Reorganization is in the best interests of the SSR Fund and that the interests of the existing shareholders of the SSR Fund will not be diluted as a result of the Reorganization;

NOW, THEREFORE, in consideration of the premises and of the covenants and agreements hereinafter set forth, the parties hereto covenant and agree as follows:

ARTICLE I

TRANSFER OF ASSETS OF THE SSR FUND IN EXCHANGE FOR BLACKROCK

FUND SHARES AND THE ASSUMPTION OF SSR FUND STATED LIABILITIES

AND LIQUIDATION OF THE SSR FUND

1.1 THE EXCHANGE. Subject to the terms and conditions contained herein and on the basis of the representations and warranties contained herein, the SSR Fund agrees to convey, transfer and deliver the assets of the SSR Fund described in paragraph 1.2 to the BlackRock Fund free and clear of all liens, encumbrances and claims whatsoever. In exchange, the BlackRock Fund agrees: (a) to deliver to the SSR Fund the number of full and fractional shares of each corresponding class of BlackRock Fund, determined by dividing: (i) the aggregate value of the SSR Fund’s assets, net of the liabilities of the SSR Fund, attributable to each share class of the SSR Fund (as set forth below), computed in the manner and as of the time and date set forth in paragraph 2.1, by (ii) the net asset value of one BlackRock Fund Share of the corresponding class (as set forth below) computed in the manner and as of the time and date set forth in paragraph 2.2; and (b) to assume the Stated Liabilities of the SSR Fund described in paragraph 1.3. Such transactions shall take place at the closing (the “Closing”) provided for in paragraph 3.1.

The classes of shares of the BlackRock Fund correspond to the classes of shares of the SSR Fund as follows: Investor A shares of the BlackRock Fund correspond to Class A and Class B shares of the SSR Fund; Investor B shares of the BlackRock Fund correspond to Class B(1) shares of the SSR Fund; Investor C shares of the BlackRock Fund correspond to Class C shares of the SSR Fund; and Institutional Shares of the BlackRock Fund correspond to Class S shares of the SSR Fund.

1.2 ASSETS TO BE ACQUIRED. The assets of the SSR Fund to be acquired by the BlackRock Fund shall consist of all property owned by the SSR Fund, including, without limitation, all cash, securities, commodities, interests in futures and other financial instruments, claims (whether absolute or contingent, known or unknown), receivables (including dividends, interest, principal, subscriptions and other receivables), goodwill and other intangible property, all books and records belonging to the SSR Fund, any deferred or prepaid expenses shown as an asset on the books of the SSR Fund on the Closing Date, and all interests, rights, privileges and powers, other than cash in an amount necessary to pay dividends and distributions as provided in paragraph 7.3 and other than the SSR Fund’s rights under this Agreement (the “Assets”).

The SSR Fund will, within 7 days prior to the Closing Date, furnish the BlackRock Fund with (a) a list of the SSR Fund’s portfolio securities and other investments and (b) a list of the SSR Fund’s “historic business assets,” which are defined for this purpose as (i) those assets that were acquired by the SSR Fund prior to the date of the approval by the board of directors of Metropolitan Life Insurance Company’s sale of SSRM Holdings, Inc., an indirect parent of the investment adviser to the Selling Trust, to BlackRock, Inc., an indirect parent of the investment adviser to the Acquiring Trust, and (ii) those assets that were acquired subsequent to such board approval but in accordance with the SSR Fund’s investment objectives and not with a view to, or in anticipation or as part of, the Reorganization. The BlackRock Fund will, within 3 days prior to the Closing Date, furnish the SSR Fund with a list of the securities and other instruments, if any, on the SSR Fund’s list referred to above that

do not conform to the BlackRock Fund’s investment objectives, policies and restrictions. If requested by the BlackRock Fund, the SSR Fund will dispose of securities and other instruments on the BlackRock Fund’s list before the Closing Date. In addition, if it is determined that the portfolios of the SSR Fund and the BlackRock Fund, when aggregated, would contain investments exceeding certain percentage limitations imposed upon the BlackRock Fund with respect to such investments, the SSR Fund, if requested by the BlackRock Fund, will dispose of a sufficient amount of such investments as may be necessary to avoid violating such limitations as of the Closing Date. After the SSR Fund furnishes the BlackRock Fund with the list described above, the SSR Fund will not, without the prior approval of the Acquiring Trust on behalf of the BlackRock Fund, acquire any additional securities other than securities which the BlackRock Fund is permitted to purchase, pursuant to its investment objective and policies or otherwise (taking into consideration its own portfolio composition as of such date). Notwithstanding the foregoing, (a) nothing herein will require the SSR Fund to dispose of any portfolios, securities or other investments, if, in the reasonable judgment of the SSR Fund’s trustees or investment adviser, such disposition would adversely affect the tax-free nature of the Reorganization for federal income tax purposes or would otherwise not be in the best interests of the SSR Fund and (b) nothing will permit the SSR Fund to dispose of any portfolio securities or other investments if, in the reasonable judgment of the BlackRock Fund’s trustees or investment adviser, such disposition would adversely affect the tax-free nature of the Reorganization for federal income tax purposes or would otherwise not be in the best interests of the SSR Fund.

1.3 LIABILITIES TO BE ASSUMED. The SSR Fund will endeavor to identify and discharge, to the extent practicable, all of its liabilities and obligations, including all liabilities relating to operations, before the Closing Date. The BlackRock Fund shall assume only those accrued and unpaid liabilities of the SSR Fund set forth in the SSR Fund’s statement of assets and liabilities as of the Closing Date delivered by the SSR Fund to the BlackRock Fund pursuant to paragraph 5.2 (the “Stated Liabilities”).

On or as soon as practicable after the Closing Date the SSR Fund will distribute in complete liquidation of the SSR Fund, pro rata to its shareholders of record, determined as of the close of business on the Closing Date (the “SSR Fund Shareholders”), all of the BlackRock Fund Shares received by the SSR Fund. Upon completion of the distribution of all of the BlackRock Fund shares in accordance with the prior sentence, the SSR Fund will thereupon proceed to dissolve and terminate as set forth in paragraph 1.10 below. Such distribution will be accomplished by the transfer on the books of the BlackRock Fund of BlackRock Fund Shares credited to the account of the SSR Fund to open accounts on the share records of the BlackRock Fund in the name of the SSR Fund Shareholders, and representing the respective pro rata number of each class of BlackRock Fund Shares due SSR Fund Shareholders holding the corresponding class of SSR Fund shares. All issued and

outstanding shares of the SSR Fund will, simultaneously with the liquidation, be cancelled on the books of the SSR Fund and will be null and void. The BlackRock Fund shall not issue certificates representing BlackRock Fund Shares in connection with such transfer, however, the BlackRock Fund shall issue such certificates upon written request.

1.7 OWNERSHIP OF SHARES. Ownership of BlackRock Fund Shares will be shown on the books of the BlackRock Fund’s transfer agent.

1.8 TRANSFER TAXES. Any transfer taxes payable upon the issuance of BlackRock Fund Shares in a name other than the registered holder of the SSR Fund shares on the books of the SSR Fund as of that time shall, as a condition of such transfer, be paid by the person to whom such BlackRock Fund Shares are to be issued and transferred.

1.9 REPORTING RESPONSIBILITY. Any reporting responsibility of the SSR Fund, including, without limitation, the responsibility for filing of regulatory reports, tax returns or other documents with the Securities and Exchange Commission (the “Commission”), any state securities commission, and any federal, state or local tax authorities or any other relevant regulatory authority, is and shall remain the responsibility of the SSR Fund, or the Selling Trust on behalf of the SSR Fund.

1.10 TERMINATION AND DISSOLUTION. The SSR Fund shall be terminated and dissolved promptly following all distributions made pursuant to paragraph 1.6 in accordance with the laws of the Commonwealth of Massachusetts and the federal securities laws.

1.11 BOOKS AND RECORDS. Immediately after the Closing Date, the share transfer books relating to the SSR Fund shall be closed and no transfer of shares shall thereafter be made on such books.

ARTICLE VIII

FURTHER CONDITIONS PRECEDENT TO OBLIGATIONS OF EACH OF THE

BLACKROCK FUND AND SSR FUND

If any of the conditions set forth below shall not have been satisfied on or before the Closing Date or shall not remain satisfied with respect to the SSR Fund or the BlackRock Fund, the other party to this Agreement shall, at its option, not be required to consummate the transactions contemplated by this Agreement:

8.1 This Agreement and the transactions contemplated herein, with respect to the SSR Fund, shall have been approved by the requisite vote of the holders of the outstanding shares of the SSR Fund in accordance with the provisions of the Selling Trust’s agreement and declaration of trust and bylaws, applicable Massachusetts law and the 1940 Act. Evidence of such approval shall have been delivered to the BlackRock Fund, in such form as shall be reasonably acceptable to the BlackRock Fund. Notwithstanding anything herein to the contrary, neither the BlackRock Fund nor the SSR Fund may waive the conditions set forth in this paragraph 8.1.

8.2 The Commission shall not have issued an unfavorable report under Section 25(b) of the 1940 Act, or instituted any proceeding seeking to enjoin the consummation of the transactions contemplated by this Agreement under Section 25(c) of the 1940 Act.

8.3 All third party consents and all consents, orders and permits of federal, state and local regulatory authorities (including those of the Commission and of state securities authorities, including any necessary “no-action” positions and exemptive orders from such federal authorities) in each case required to permit consummation of the transactions contemplated herein shall have been obtained, except where failure to obtain any such consent, order or permit would not reasonably be expected to have a material adverse effect on the assets or properties of the BlackRock Fund or the SSR Fund, provided that either party hereto may waive any such conditions for itself.

8.4 The Registration Statement shall have become effective under the 1933 Act, and no stop orders suspending the effectiveness thereof shall have been issued. To the best knowledge of the parties to this Agreement, no investigation or proceeding for that purpose shall have been instituted or be pending, threatened or contemplated under the 1933 Act. The registration statement of the Acquiring Trust on Form N-1A under the 1940 Act covering the sale of shares of the BlackRock Fund shall be effective.

8.5 As of the Closing Date, there shall be no pending litigation brought by any person against the Selling Trust, the SSR Fund, the Acquiring Trust or the BlackRock Fund or any of the investment advisers, trustees or officers of the foregoing, arising out of, or seeking to prevent completion of the transactions contemplated by, this Agreement. Furthermore, no action, suit or other proceeding shall be pending before any court or governmental agency in which it is sought to restrain or prohibit, or obtain damages or other relief in connection with, this Agreement or the transactions contemplated herein.

8.6 The Acquiring Trust and the Selling Trust each shall have received an opinion of Skadden, Arps, Slate, Meagher & Flom LLP, special counsel to the BlackRock Fund substantially to the effect that, based on certain facts, assumptions and representations of the parties, for federal income tax purposes:

(a) the transfer of all of the Assets solely in exchange for BlackRock Fund Shares and the assumption by the BlackRock Fund of the Stated Liabilities of the SSR Fund followed by the distribution of BlackRock Fund Shares to the SSR Fund Shareholders in complete dissolution and liquidation of the SSR Fund will constitute a “reorganization” within the meaning of Section 368(a) of the Code and the BlackRock Fund and the SSR Fund will each be a “party to a reorganization” within the meaning of Section 368(b) of the Code;

(b) no gain or loss will be recognized by the BlackRock Fund upon the receipt of all of the Assets solely in exchange for BlackRock Fund Shares and the assumption by the BlackRock Fund of the Stated Liabilities of the SSR Fund;

(c) no gain or loss will be recognized by the SSR Fund upon the transfer of the Assets to the BlackRock Fund solely in exchange for BlackRock Fund Shares and the assumption by the BlackRock Fund of the Stated Liabilities of the SSR Fund or upon the distribution (whether actual or constructive) of BlackRock Fund Shares to SSR Fund Shareholders in exchange for such shareholders’ shares of the SSR Fund in liquidation of the SSR Fund;

(d) no gain or loss will be recognized by the SSR Fund Shareholders upon the exchange of their SSR Fund shares solely for BlackRock Fund Shares in the Reorganization;

(e) the aggregate tax basis of BlackRock Fund Shares received by each SSR Fund Shareholder pursuant to the Reorganization will be the same as the aggregate tax basis of the SSR Fund shares exchanged therefor by such shareholder;

(f) the holding period of BlackRock Fund Shares to be received by each SSR Fund Shareholder pursuant to the Reorganization will include the period during which the SSR Fund shares exchanged therefor were held by such shareholder, provided such SSR Fund shares are held as capital assets at the time of the Reorganization;

(g) the tax basis of the Assets acquired by the BlackRock Fund will be the same as the tax basis of such Assets to the SSR Fund immediately before the Reorganization; and

(h) the holding period of the Assets in the hands of the BlackRock Fund will include the period during which those assets were held by the SSR Fund.

Such opinion shall be based on customary assumptions and such representations as Skadden, Arps, Slate, Meagher & Flom LLP may reasonably request, and each SSR Fund and BlackRock Fund will cooperate to make and certify the accuracy of such representations. Notwithstanding anything herein to the contrary, neither the BlackRock Fund nor the SSR Fund may waive the condition set forth in this paragraph 8.7.

8.7 The transactions contemplated under the Stock Purchase Agreement (the “Stock Purchase Agreement”) by and among MetLife, Inc., Metropolitan Life Insurance Company, SSRM Holdings, Inc., BlackRock, Inc. and BlackRock Financial Management, Inc., dated August 25, 2004, shall have been consummated.

ARTICLE IX

EXPENSES

Except as otherwise expressly provided in this Agreement, SSRM Holdings, Inc. shall bear the direct and indirect expenses incurred by the SSR Fund, and BlackRock, Inc. shall bear the direct and indirect expenses incurred by the BlackRock Fund, each in connection with the purchase and sale of assets and liquidation and dissolution of the SSR Fund contemplated by the provisions of this Agreement, including all direct and indirect expenses and out-of-pocket costs.

ARTICLE XI

TERMINATION

(b) a condition herein expressed to be precedent to the obligations of the terminating party or both parties that has not been met if it reasonably appears that it will not or cannot be met; or

In the event of willful default, all remedies at law or in equity of the party adversely affected shall survive.

ARTICLE XII

AMENDMENTS

12.1 This Agreement may be amended, modified or supplemented in such manner as may be mutually agreed upon in writing by the officers of the Acquiring Trust and the Selling Trust as specifically authorized by their respective Board of Trustees; provided, however, that, following the meeting of the SSR Fund Shareholders called by the SSR Fund pursuant to paragraph 4.1(r) of this Agreement, no such amendment may have the effect of changing the provisions for determining the number of BlackRock Fund Shares to be issued to the SSR Fund Shareholders under this Agreement to the detriment of such SSR Fund Shareholders without their further approval.

STATEMENT OF ADDITIONAL INFORMATION

[ ], 2004

This Statement of Additional Information (the “SAI”) relates to the proposed reorganization (the “Reorganization”) of the State Street Research Health Sciences Fund (the “SSR Fund”), a series of State Street Research Financial Trust, a Massachusetts business trust, into the BlackRock Health Sciences Portfolio (the “BlackRock Fund”), a newly created series of BlackRock Funds, a Massachusetts business trust.

This SAI contains information which may be of interest to shareholders relating to the Reorganization, but which is not included in the Combined Prospectus/Proxy Statement dated [ ], 2004 (the “Combined Prospectus/Proxy Statement”) of the BlackRock Funds. As described in the Combined Prospectus/Proxy Statement, the Reorganization would involve the transfer of all the assets of, and the assumption of substantially all the liabilities of, the SSR Fund, in exchange for shares of the BlackRock Fund. The SSR Fund would distribute the BlackRock Fund shares it receives to its shareholders in complete liquidation of the SSR Fund.

This SAI is not a prospectus, and should be read in conjunction with the Combined Prospectus/Proxy Statement. The Combined Prospectus/Proxy Statement has been filed with the Securities and Exchange Commission, and is available upon request and without charge by writing to State Street Research Financial Trust, One Financial Center, Boston, Massachusetts 02111, or by calling 1-877-773-8637.

OTHER INFORMATION

ITEM 15.

INDEMNIFICATION

Indemnification of BlackRock Funds’ principal underwriter against certain losses is provided for in Section 9 of the Distribution Agreement incorporated by reference herein as Exhibit 7(a). Indemnification of BlackRock Funds’ Custodian, Transfer Agent and Administrators is provided for, respectively, in Section 12 of the Custodian Agreement incorporated by reference herein as Exhibit 9(a), Section 12 of the Transfer Agency Agreement incorporated by reference herein as Exhibit 13(c) and Section 9 of the Administration Agreement incorporated by reference herein as Exhibit 13(a). BlackRock Fund intends to obtain from a major insurance carrier a trustees’ and officers’ liability policy covering certain types of errors and omissions. In addition, Section 9.3 of the BlackRock Fund’s Declaration of Trust incorporated by reference herein as Exhibit 1(a) provides as follows:

Indemnification of Trustees, Officers, Representatives and Employees. The Trust shall indemnify each of its Trustees against all liabilities and expenses (including amounts paid in satisfaction of judgments, in compromise, as fines and penalties, and as counsel fees) reasonably incurred by him in connection with the defense or disposition of any action, suit or other proceeding, whether civil or criminal, in which he may be involved or with which he may be threatened, while as a Trustee or thereafter, by reason of his being or having been such a Trustee except with respect to any matter as to which he shall have been adjudicated to have acted in bad faith, willful misfeasance, gross negligence or reckless disregard of his duties, provided that as to any matter disposed of by a compromise payment by such person, pursuant to a consent decree or otherwise, no indemnification either for said payment or for any other expenses shall be provided unless the Trust shall have received a written opinion from independent legal counsel approved by the Trustees to the effect that if either the matter of willful misfeasance, gross negligence or reckless disregard of duty, or the matter of bad faith had been adjudicated, it would in the opinion of such counsel have been adjudicated in favor of such person. The rights accruing to any person under these provisions shall not exclude any other right to which he may be lawfully entitled, provided that no person may satisfy any right of indemnity or reimbursement hereunder except out of the property of the Trust. The Trustees may make advance payments in connection with the indemnification under this Section 9.3, provided that the indemnified person shall have given a written undertaking to reimburse the Trust in the event it is subsequently determined that he is not entitled to such indemnification.

The Trustee shall indemnify officers, representatives and employees of the Trust to the same extent that Trustees are entitled to indemnification pursuant to this Section 9.3.

Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to trustees, officers and controlling persons of Registrant pursuant to the foregoing provisions, or

C-1

otherwise, Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by Registrant of expenses incurred or paid by a trustee, officer or controlling person of Registrant in the successful defense of any action, suit or proceeding) is asserted by such trustee, officer or controlling person in connection with the securities being registered, Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

Section 9.6 of the BlackRock Funds’ Declaration of Trust, filed herein as Exhibit 1(a), also provides for the indemnification of shareholders of BlackRock Funds. Section 9.6 states as follows:

Indemnification of Shareholders. In case any Shareholder or former Shareholder shall be held to be personally liable solely by reason of his being or having been a Shareholder and not because of his acts or omissions or for some other reason, the Shareholder or former Shareholder (or his heirs, executors, administrators or other legal representatives or, in the case of a corporation or other entity, its corporate or other general successor) shall be entitled out of the assets belonging to the classes of Shares with the same alphabetical designation as that of the Shares owned by such Shareholder to be held harmless from and indemnified against all loss and expense arising from such liability. The Trust shall, upon request by the Shareholder, assume the defense of any claim made against any Shareholder for any act or obligations of the Trust and satisfy any judgment thereon from such assets.
