Dear Shareholder:

The 2013 Joint Annual Meeting of Shareholders (the “Meeting”) of Babson Capital Corporate Investors (“MCI”) and Babson Capital Participation Investors (“MPV” and, together with MCI, each is referred to separately as the “Trust” and collectively as the “Trusts”) will be held in the Oak Room of Massachusetts Mutual Life Insurance Company, 1295 State Street, Springfield, Massachusetts 01111, at 1:00 p.m., Eastern Time, on Friday, April 19, 2013. A Notice and a Proxy Statement regarding the Meeting, proxy card(s) for your vote at the Meeting, and a postage prepaid envelope in which to return your proxy card(s) are enclosed.

By promptly returning the enclosed proxy card(s) or by voting on the internet you can help the Trusts avoid the expense of sending follow-up letters to obtain the attendance of a majority of the outstanding shares. You are earnestly requested to vote your proxy in order that the necessary quorum may be represented at the Meeting. If you later find that you can be present in person, you may, if you wish, revoke your proxy then and vote your shares in person.

At the meeting, shareholders of each Trust will be asked to vote on two proposals. The following Q&A is provided to assist you in understanding the proposals.

I look forward to your attendance at this Meeting because it will provide us with an opportunity to inform you about the progress of the Trusts.

Sincerely,

Clifford M. Noreen

Chairman

IMPORTANT INFORMATION TO HELP YOU UNDERSTAND AND PROVIDE

VOTING INSTRUCTIONS ON THE PROPOSALS

The following Q&A is provided to assist you in understanding the proposals. Each of the proposals is described in greater detail in the enclosed Proxy Statement. Please read the full text of the Proxy Statement. Your voting instructions are important.

What proposals am I being asked to vote on?

Depending on the Trust in which you have an interest, you may be asked to provide voting instructions on one or more of the following proposals for each Trust:

1. To elect three Trustees to serve on the Board of Trustees;

2. To make MCI’s and MPV’s fundamental investment objectives non-fundamental.

How do the Trustees recommend that I vote?

The Trustees recommend that shareholders vote FOR each of the proposals.

PROPOSAL 1.

TO ELECT THREE TRUSTEES TO SERVE ON THE BOARD OF TRUSTEES.

What are shareholders being asked to do?

Shareholders are being asked to consider the re-election of two of the current Trustees, Edward P. Grace, III and Robert E. Joyal. In addition, shareholders are being asked to elect Susan B. Sweeney, who has served as a Trustee of the Trusts since April 2012.

Will a majority of the Trustees be independent of Babson Capital?

Yes. Following the meeting, five of seven members of each Trust’s Board will be “Independent Trustees.” Only two Trustees will be considered “interested persons” of each Trust under the Investment Company Act of 1940, as amended (the “1940 Act”), which is the federal statute that governs the management and administration of registered investment companies, such as the Trusts.

PROPOSAL 2.

TO MAKE MCI’S AND MPV’S FUNDAMENTAL INVESTMENT

OBJECTIVES NON-FUNDAMENTAL.

What is the purpose of these proposed changes?

Generally, the purpose of these proposed changes is to increase the investment flexibility of each Trust by permitting the Boards of Trustees to react to changing market conditions or other developments by modifying each Trust’s investment objective without the delay and expense associated with a proxy solicitation. These changes are also consistent with the structure of more recently launched funds whose investment objectives are not fundamental.

How will these changes benefit me as a shareholder?

Making these changes will empower the Trustees to approve changes to each Trust’s investment objective in the future without the costs and delays of a shareholder vote.

If this proposal is approved, will Babson Capital be proposing changes to each Trust’s investment objective?

Yes. If this proposal is approved, the Trustees have approved certain changes to the investment objective of each Trust to remove the requirement that its investments in direct placement securities (for MCI) and the requirement that at least half of its investments in private placement securities (for MPV) be accompanied by equity features. Babson Capital has advised the Trustees that direct placement securities and private placement securities accompanied by equity features have, in the last few years, become increasingly less common than they were when the Trusts were launched. While Babson Capital expects to continue to seek investments with equity features and to consider the relative attractiveness of such features when evaluating competing investment opportunities, Babson Capital believes that the proposed changes will offer the Trusts increased investment flexibility. The Boards and Babson Capital believe that it would be in the best interest of each Trust and its shareholders to permit each Trust to invest (for MCI), or to invest more than half of its investments (for MPV), in direct placement securities and private placement securities, respectively, that are not accompanied by equity features.

Joint Proxy Statement

This Proxy Statement is furnished in connection with the solicitation of proxies by the Board of Trustees of Babson Capital Corporate Investors (“MCI”) and of Babson Capital Participation Investors (“MPV” and, together with MCI, each is referred to separately as the “Trust” and collectively as the “Trusts”) for use at the Annual Meeting of its Shareholders (the “Annual Meeting” or “Meeting”), to be held in the Oak Room of Massachusetts Mutual Life Insurance Company (“MassMutual”), 1295 State Street, Springfield, Massachusetts 01111, on Friday, April 19, 2013, at 1:00 p.m., Eastern Time. Unless otherwise indicated, all information in this Proxy Statement and each Proposal (“Proposal”) applies separately to each Trust.

This Proxy Statement and the accompanying letter to shareholders from the Chairman of the Board of Trustees, Notice of Annual Meeting of Shareholders, and proxy card(s) are being mailed on or about March 12, 2013, to shareholders of record on February 19, 2013, the “record date”. Each Trust’s principal business office is c/o Babson Capital Management LLC (“Babson Capital”), 1500 Main Street, P.O. Box 15189, Springfield, Massachusetts 01115-5189.

Holders of the shares of beneficial interest of each Trust (“shares”) of record at the close of business on February 19, 2013 will be entitled to one vote per share on all business of the Meeting and any adjournments thereof. There were 19,239,673 shares of MCI outstanding and 10,183,249 shares of MPV outstanding on the record date. The Trusts, to the best of their knowledge, are not aware of any beneficial owner of more than 5% of the outstanding shares of each Trust. However, MassMutual, the ultimate parent company of Babson Capital, may be deemed a beneficial owner of more than 5% of the outstanding shares of MCI by reason of it owning a $30,000,000 Senior Fixed Rate Convertible Note due November 15, 2017 (the “MCI Note”) issued by MCI. Similarly, MassMutual may be deemed a beneficial owner of more than 5% of the outstanding shares of MPV by reason of it owning a $15,000,000 Senior Fixed Rate Convertible Note due December 13, 2023 issued by MPV (the “MPV Note and, together with “MCI Note,” each a “Note” and collectively the “Notes”). MassMutual, at its option, can convert the principal amount of each Note into shares. The dollar amount of principal would be converted into an equivalent dollar amount of shares based upon the average price of the shares for ten business days prior to the notice of conversion.

The Trusts have engaged Broadridge Financial Solutions, Inc. (“Broadridge”) to provide shareholder meeting services, including vote solicitation and tracking. Should you have any questions about this Proxy Statement, please contact the proxy solicitor of Broadridge by calling (toll-free) 1-855-742-8273.

Important Notice regarding the availability of Proxy Materials for the Shareholder Meeting to be held on Friday, April 19, 2013. The Joint Proxy Statement is available on https://www.proxyvote.com or on each Trust’s website at www.babsoncapital.com/mci and www.babsoncapital.com/mpv.

The following provides an overview of the considerations that led the Board to conclude that each individual serving as a Trustee or nominee for Trustee of each Trust should so serve. The current members of the Board have joined the Board at different points in time since 2003. Generally, no one factor was decisive in the original selection of an individual to join the Board. Among the attributes common to all Trustees is their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with each Trust’s investment adviser, counsel and independent auditors, and to exercise effective business judgment in the performance of their duties as Trustees. In recommending the election or appointment of the current Board members as Trustees, the Nominating Committee generally considered (i) the educational, business and professional experience of each individual; (ii) the individual’s record of service as a director or trustee of public or private organizations; and (iii) how the individual’s skills, experience and attributes would contribute to an appropriate mix of relevant skills and experience on the Board. The Nominating Committee also considered that during their service as members of the Board of Trustees of each Trust, the Trustees have demonstrated a high level of diligence and commitment to the interests of the Trusts’ shareholders and the ability to work effectively and collegially with other members of the Board.

The following summarizes each Trustee’s or nominee for Trustee’s professional experience and additional considerations that contributed to the Board’s conclusion that each individual should serve on the Board.

Mr. Barrett – Mr. Barrett brings over 30 years of investment banking experience to each Board.

Ms. Syracuse’s previous positions include her work as an investment banker at JP Morgan Securities, Inc. and Deutsche Bank Securities (f/k/a Banker’s Trust Company).

Share Ownership of Trustees and Officers

As of January 25, 2013, the Trustees and Officers of each Trust individually beneficially owned less than one percent (1%) of each of MCI’s and MPV’s outstanding shares and as a group beneficially owned 1.95% of MCI’s outstanding shares and 1.92% of MPV’s outstanding shares. This information is based on information furnished by each Trustee and Officer. Beneficial ownership has been determined in accordance with Rule 16a-1(a)(2) under the Securities and Exchange Act of 1934, as amended (the “Exchange Act”). Also, as of January 25, 2013, Babson Capital, the investment adviser to each Trust, beneficially owned 0.86% of the outstanding shares of MCI and 1.41% of the outstanding shares of MPV.

Members of each Board of Trustees historically have invested in one or both of the Trusts, as is consistent with their individual financial goals. In October 2010, this policy was formalized through adoption of a requirement that each Independent Trustee invest one year’s worth of fees received for serving as Trustee of the Trusts (excluding committee fees) in shares of one or both of the Trusts. Investments in the name of family members or entities controlled by a Trustee constitute Trust holdings of such Trustee for purposes of this policy, and a three-year phase-in period applies to such investment requirements for Trustees and newly elected Trustees. In implementing such policy, a Board member’s Trust holdings existing on October 22, 2010, are valued as of such date with subsequent investments valued at cost.

The table below sets forth information regarding the beneficial ownership* of each Trust’s shares by each Trustee and the Officers beneficially owning shares based on the market value of such shares as of January 25, 2013.

Required Vote

If a quorum is present at the Meeting, the three nominees for election as Trustees who receive a plurality vote, meaning the greatest number of affirmative votes cast by shareholders, will be elected as Trustees.

THE BOARDS, INCLUDING THE INDEPENDENT TRUSTEES, UNANIMOUSLY RECOMMEND THAT THE SHAREHOLDERS OF EACH TRUST VOTE TO ELECT EACH OF THE NOMINEES AS TRUSTEE OF EACH TRUST.

Board Leadership Structure

The Board for each Trust currently consists of nine Trustees, seven of whom are Independent Trustees. As discussed below, three of the standing committees of the Board, to which the Board has delegated certain authority and oversight responsibilities, are comprised exclusively of Independent Trustees.

Mr. Noreen, an “interested person” of each Trust, as defined in Section 2(a)(19) of the 1940 Act, serves as Chairman of each Board of Trustees. Mr. Noreen presides at meetings of each Board and acts as a liaison with service providers, officers, and other Trustees generally between meetings, and performs such other functions as may be requested by each Board from time to time. The Independent Trustees have not designated a lead Independent Trustee, but the Chairman of the Audit Committee, Mr. Benson, generally acts as chairman of meetings or executive sessions of the Independent Trustees, and when appropriate, represents the views of the Independent Trustees to management. The Board of each Trust reviews its leadership structure periodically and believes that the leadership structure is appropriate to enable each Board to exercise its oversight of each Trust. Each Board also believes that its structure, including the active role of the Independent Trustees, facilitates an efficient flow of information concerning the management of each Trust to the Independent Trustees.

Each Board provides oversight of the services provided by Babson Capital, including risk management activities. In addition, each committee of each Board provides oversight of Babson Capital’s risk activities with respect to the particular activities within the committee’s purview. In the course of providing oversight, the Board and relevant committees for each Trust receive a wide range of reports on the Trusts’ activities, including each Trust’s investment portfolio, the compliance of the Trusts with applicable laws, and the Trusts’ financial accounting and reporting. The Board and Audit Committee for each Trust meet periodically with the Trusts’ Chief Compliance Officer regarding the compliance of the Trusts with federal securities laws and the Trusts’ internal compliance policies and procedures. In addition, both the Audit Committee and the full Board of each Trust regularly review information and materials concerning risks specific to the Trusts and Babson Capital, including presentations by various officers of the Trusts, investment personnel for the Trusts, Babson Capital, Corporate Audit, the independent auditors for the Trusts (KPMG LLP) and Counsel to the Trusts.

Information Concerning Committees and Meetings of the Board of Trustees

Each Board of Trustees has an Audit Committee, a Joint Transactions Committee, a Governance Committee and a Nominating Committee.

The Audit Committee of each Trust is comprised exclusively of Trustees who are not “interested persons” of the Trust, as defined in Section 2(a)(19) of the 1940 Act, and operates pursuant to a written Audit Committee Charter, which is available on each Trust’s website, www.babsoncapital.com/mci and www.babsoncapital.com/mpv. A print copy of the Audit Committee Charter may also be obtained by calling, toll-free, 1-866-399-1516. The present members of the Audit Committee of each Trust are Donald E. Benson (Chairman), Michael H. Brown and Maleyne M. Syracuse. Each member of the Audit Committee qualifies as an “Independent Trustee” under the current listing standards of the New York Stock Exchange (the “Listing Standards”) and the rules of the U.S. Securities and Exchange Commission (“SEC”). In accordance with the SEC’s rules implementing Section 407 of the Sarbanes-Oxley Act of 2002 and upon due consideration of the qualifications of each member of each Trust’s Audit Committee, each Board designated Mr. Benson as the Trust’s Audit Committee Financial Expert.

In accordance with the standards set forth in the Audit Committee Charter of each Trust, the Audit Committee is responsible for: oversight matters; financial statement and disclosure oversight matters; matters related to the hiring, retention, and oversight of each Trust’s independent accountants; certain accounting and audit related oversight matters; and certain other matters as set forth in the Audit Committee Charter. During the twelve months ended December 31, 2012, the Audit Committee held eight meetings.

The Joint Transactions Committee of each Trust is comprised of all Trustees who are not “interested persons” of the Trust, as defined in Section 2(a)(19) of the 1940 Act. This Committee reviews certain joint investment transactions between each Trust and MassMutual pursuant to the conditions set forth in the Trust’s SEC exemptive order under Section 17(d) of the 1940 Act and Rule 17d-1 thereunder. This Committee acts primarily by written consent (eighteen consents were executed by Committee members, approving thirty-three investments and turning down two investments during the past fiscal year). The Committee also met five times during the year in conjunction with meetings of each Trust’s Board of Trustees.

The Governance Committee of each Trust is currently comprised of Robert E. Joyal (Chairman), William J. Barrett, Michael H. Brown, Donald Glickman and Maleyne M. Syracuse. The Governance Committee considers, evaluates and makes recommendations to the Board of Trustees of each Trust with respect to the structure, membership and function of the Board of Trustees and the Committees thereof, including the compensation of the Trustees. During the twelve months ended December 31, 2012, the Governance Committee held one meeting.

The Nominating Committee of each Trust currently is comprised of all Independent Trustees and is chaired by William J. Barrett. A current copy of each Trust’s Nominating Committee Charter can be found on each Trust’s website, www.babsoncapital.com/mci and www.babsoncapital.com/mpv. This Committee met four times during fiscal year 2012.

The Nominating Committee is responsible for identifying and nominating individuals to serve as Trustees who are not “interested persons” of each Trust (“Independent Trustees”). The Nominating Committee Charter contemplates that all nominees for Independent Trustees have a college degree or, in the judgment of the Committee, equivalent business experience. In addition, the Committee may take into account a wide variety of factors in considering Trustee candidates, giving such weight to any individual factor(s) as it deems appropriate, including but not limited to: availability and commitment of a candidate to attend meetings and perform his or her responsibilities on each Board; relevant industry and related experience; educational background; depth and breadth of financial expertise; and an assessment of the candidate’s ability, judgment, expertise, reputation, and integrity. In the case of a shareholder recommended candidate, the Committee may also consider any other facts and circumstances attendant to such shareholder submission as may be deemed appropriate by the Committee. Different factors may assume greater or lesser significance at particular times, in light of the Board’s present composition and the Committee’s (or the Board’s) perceptions about future issues and needs.

When each Board has or expects to have a vacancy for an Independent Trustee, the Nominating Committee will consider candidates recommended by each Trust’s current Trustees; each Trust’s shareholders; each Trust’s officers; each Trust’s investment adviser; and any other source the Committee deems to be appropriate. Shareholder recommendations to fill vacancies on the Board for Independent Trustees must be submitted in accordance with the provisions of the Nominating Committee Charter, which requires that shareholder recommendations be timely received, and contain biographical and other necessary information regarding the candidate that would be required for the Trust to meet its disclosure obligations under the proxy rules. The Nominating Committee will evaluate nominee candidates properly submitted by shareholders in the same manner as it evaluates candidates recommended by other sources.

During the past fiscal year, each Board of Trustees held five regular meetings (one of which was held by means of a telephone conference call). During the past fiscal year, each Trustee of each Trust attended all of the meetings of the Board of Trustees and all of the Committees of the Board on which s/he served.

Transactions with and Remuneration of Officers and Trustees

Pursuant to the Investment Services Contract between MCI and Babson Capital and the Investment Advisory and Administrative Services Contract between MPV and Babson Capital (each a “Contract”), Babson Capital paid the compensation and expenses of the Trusts’ officers and of all Trustees of the Trusts who were officers or employees of Babson Capital.

Trustees who are not officers or employees of Babson Capital receive an annual retainer paid by MCI of $30,000 and by MPV of $20,000. Each Trust also pays an additional annual retainer fee to the Chairman of the Audit Committee in the amount of $3,000. Trustees of MCI also receive a fee of $3,000 and Trustees of MPV receive a fee of $2,000 for each meeting of each Board which they attend ($1,500 and $1,000, respectively, for each meeting conducted by telephone conference call). Members of the Audit

Committee, Nominating Committee and Governance Committee of each Trust receive an additional fee of $1,800 from MCI and $1,200 from MPV per meeting attended, including meetings conducted by telephone conference call. During the fiscal year ended December 31, 2012, the aggregate direct remuneration to these Trustees and reimbursement of their out-of-pocket expenses paid was approximately $457,918 for MCI and $311,218 for MPV.

The following table discloses the compensation paid to each Trust’s Trustees (not including reimbursement for out-of-pocket expenses) for the fiscal year ended December 31, 2012. The Trusts, Babson Capital Global Short Duration High Yield Fund, MassMutual Premier Funds, MML Series Investment Funds, MassMutual Select Funds, and MML Series Investment Funds II are collectively referred to in the table below as the “Fund Complex”.

PROPOSAL 2

CONVERSION OF EACH TRUST’S INVESTMENT OBJECTIVE

FROM FUNDAMENTAL TO NON-FUNDAMENTAL

Summary Description of the Proposal

Shareholders of MCI and MPV are being asked to approve the conversion of their respective investment objective from “fundamental” (i.e., cannot be changed without shareholder approval) to “non-fundamental” (i.e., can be changed by the Boards without shareholder approval). If this proposal is approved, the Boards will have the authority to modify each Trust’s investment objective in the future without shareholder approval.

Background

Each Trust is a closed-end management investment company registered under the 1940 Act. At the time that MCI and MPV were launched, in 1971 and 1988, respectively, it was not uncommon to have an investment objective that was fundamental, meaning it could not be changed without shareholder approval. For more recently launched funds, however, it has become common to have an investment objective that is non-fundamental, meaning that it can be changed by the Boards without shareholder approval. Classifying the investment objective as non-fundamental would afford the Boards more flexibility to respond to changes in the market, while avoiding the costs and delays associated with a shareholder vote.

Based on input and recommendations from Babson Capital, the Boards have determined that making each Trust’s investment objective non-fundamental is in the best interest of the Trusts and their respective shareholders, and recommend the same for approval by shareholders. The Boards considered that making this change will empower the Boards to approve changes to each Trust’s investment objective in the future in response to changing market conditions or other developments without the delay and expense of a proxy solicitation. In addition, Babson Capital and the Boards took into account that this change would bring the Trusts in line with other more recently organized funds. If this proposal is approved, the Boards will have the authority to modify each Trust’s investment objective in the future without shareholder approval.

Subject to shareholder approval of this proposal, the Boards have approved certain changes to MCI’s investment objective (as so revised, the “New MCI Objective”) and to MPV’s investment objective (as so revised, the “New MPV Objective,” and together with the New MCI Objective, the “New Objectives”). Currently, MCI’s investment objective requires that its investments in long-term debt obligations and preferred stocks (“direct placement securities”) be accompanied “in each case” by interests, rights or privileges (“equity features”). MPV’s investment objective currently requires MPV to invest in privately placed fixed-income securities (“private placement securities”) “at least half of which will include equity features.” Babson Capital has advised the Boards that direct placement securities or private placement securities accompanied by equity features have in the last few years become increasingly less common than they were when the Trusts were launched, and the Boards and Babson Capital believe that it would be in the best interests of each Trust and its shareholders to permit each Trust to invest (for MCI), or

to invest more than half of its investments (for MPV), in direct placement securities or private placement securities that are not accompanied by equity features. Babson Capital believes that it will become increasingly difficult to identify a large enough number of issuances accompanied by equity features to permit the Trusts to diversify their holdings to the extent they have been able to in the past. While Babson Capital expects to continue to seek investments with equity features and to consider the relative attractiveness of such features when evaluating competing investment opportunities, Babson Capital believes that the proposed changes will offer the Trusts increasing investment flexibility. Many of MCI’s and MPV’s competitors are able to invest in direct placement securities or private placement securities without equity features and the Board believes that such change will help Babson Capital to continue to find appropriate investments and to appropriately diversify those investments for MCI and MPV. Babson Capital believes that the Trusts and their respective shareholders will benefit from the greater investment flexibility afforded by the New Objectives.

The New MCI Objective the Board has approved, subject to shareholder approval of this Proposal 2, would be as follows (marked to show changes from MCI’s current investment objective):

“Investment Objective. Registrant’s investment objective is to maintain a portfolio of securities providing a fixed yield and at the same time offering an opportunity for capital profits. Registrant invests, by direct purchase from issuers or dealers, in long-term debt obligations and preferred stocks (“direct placement securities”). Such direct placement securities may, in some cases, be accompanied in each case by (and forming a part of the “package” purchased) interests, rights, or privileges (“equity features”) available to the holder which, if separately transferable, will themselves provide the possibility for capital profit or, if not separately transferable, will provide the means for enhancing the value of the obligations or preferred stocks for ultimate sale. Obvious examples of such rights or privileges are rights to convert the direct placement securities into shares of common stock of the issuer or an affiliate or warrants for the purchase of such shares. However, Registrant is not limited to traditional equity features, but may find the opportunity for capital appreciation available in rights to payments contingent on the earnings of a company, rights to mineral production payments, privileges with respect to the acquisition or proceeds of sale of equity interest, or other rights or privileges.

Registrant, on the basis of experience, expects that when it realizes proceeds from the sale, payment or redemption of investments or from the issuance of securities by Registrant, new direct placement securities appropriate for investment by Registrant will not always be available. In such event, Registrant will invest such proceeds, at least temporarily, in publicly traded bonds of investment quality and in other marketable debt securities (not excluding money market instruments, commercial paper and cash equivalents where greater liquidity is deemed advisable) and, to an extent

not exceeding 5% of portfolio market value, in marketable common stocks. The value of Registrant’s total investments in this general category may at times reach as high as 50% of the market value of Registrant’s portfolio, but Registrant will in any event be seeking to apply the funds so invested at the earliest opportunity to the purchase of direct placement securities as described above.

Registrant’s investment objective cannot be changed without the vote of the holders of a majority of Registrant’s outstanding voting securities.

Registrant’s investment objective may be changed without shareholder approval.”

The New MPV Objective the Board has approved, subject to shareholder approval of this Proposal 2, would be as follows (marked to show changes from MPV’s current investment objective):

“Recital of Investment Objective. The investment objective of Registrant is to maximize total return by providing a high level of current income, the potential for growth of such income, and capital appreciation, by investment primarily in a portfolio of privately placed fixed-income securities (“Private Placement Securities”) at least half of which normally will include equity features. Registrant may also invest in publicly-traded debt obligations, with an emphasis on those with equity features, and in convertible preferred stocks (“Publicly-Traded Securities”), and temporarily in high quality, readily marketable securities, which include short-term securities issued or guaranteed by the U.S. government and agencies of the U.S. government and repurchase agreements in respect thereof, bank certificates of deposit, bankers’ acceptances, and commercial paper rated A-1 or A-2 by Standard & Poor’s Corporation or P-1 or P-2 by Moody’s Investors Services, Inc. (“Readily Marketable Securities”).

Registrant’s investment objective set forth above may not be changed without the approval of the lesser of (i) the holders of 67% or more of the voting securities of Registrant represented at a meeting if the holders of more than 50% of the outstanding voting securities are present in person or by proxy or (ii) the holders of more than 50% of the outstanding voting securities (a “Majority Shareholder Vote”).

Registrant’s investment objective may be changed without shareholder approval.”

Babson Capital and the Boards considered that the purpose of the New Objectives is to increase each Trust’s investment flexibility, and noted that financial markets have experienced meaningful changes in recent years, particularly in response to regulatory changes and the global financial crisis, as well as changing investment preferences and risk tolerance within the private equity industry. Babson Capital and the Boards considered that the competitive landscape for the Trusts’ investments (primarily corporate mezzanine debt) has changed in response to these factors. Babson Capital and the Boards also noted

that many of the Trusts’ competitors are able to invest in direct placement securities and private placement securities that are not accompanied by equity features.

If this proposal is approved, the Boards will have the authority to modify each Trust’s investment objective in the future without shareholder approval. If shareholders of either Trust do not approve this proposal, such Trust’s investment objective will remain unchanged and will continue to be “fundamental.”

Required Vote

For each of MCI and MPV, approval of this Proposal 2 requires the affirmative vote of the holders of a majority the Trust’s outstanding voting securities, which for this purpose means the affirmative vote of the lesser of (i) more than 50% of the outstanding voting securities of such Trust or (ii) 67% of more of the outstanding voting securities of such Trust present at the Meeting if more than 50% of the outstanding voting securities of the Trust are present in person or represented by proxy.

THE BOARDS, INCLUDING THE INDEPENDENT TRUSTEES, UNANIMOUSLY RECOMMEND THAT THE SHAREHOLDERS OF EACH TRUST VOTE FOR THE PROPOSAL TO MAKE EACH TRUST’S FUNDAMENTAL INVESTMENT OBJECTIVE NON-FUNDAMENTAL.

AUDIT COMMITTEE REPORT OF EACH TRUST

Each Trust’s Audit Committee oversees the Trust’s financial reporting process on behalf of each Trust’s Board of Trustees and operates under a written Charter adopted by each Trust’s Board of Trustees. The Audit Committee meets with each Trust’s management (“Management”) and independent registered public accountants and reports the results of its activities to each Trust’s Board of Trustees. Management has the primary responsibility for the financial statements and the reporting process, including the system of internal controls. In connection with each Committee’s and independent registered accountant’s responsibilities, Management advised that each Trust’s financial statements were prepared in conformity with generally accepted accounting principles.

Accordingly, each Trust’s Audit Committee has:

■	Reviewed and discussed the audited financial statements for the fiscal year ended December 31, 2012 with Management and KPMG LLP, each Trust’s independent registered public accountants;

■	Discussed with KPMG LLP those matters required to be discussed by SAS 61 (Codification of Statements on Auditing Standards); and

■	Received the written disclosure and the letter from KPMG LLP required by the Public Company Accounting Oversight Board Rule 3526 (Communications with Audit Committee Concerning Independence) and has discussed with KPMG LLP its independence.

Each Trust’s Audit Committee has also reviewed the aggregate fees billed for professional services rendered by KPMG LLP for 2011 and 2012 for each Trust and for the non-audit services provided to Babson Capital and Babson Capital’s parent, MassMutual. As part of this review, the Audit Committee considered whether the provision of such non-audit services was compatible with maintaining the principal accountant’s independence.

In reliance on the reviews and discussions referred to above, each Trust’s Audit Committee presents this Report to each Trust’s Board of Trustees and recommends that each Trust’s Board of Trustees (1) include the December 31, 2012 audited financial statements in the Annual Report to Shareholders for the fiscal year ended December 31, 2012, and (2) file such Annual Report with the Securities and Exchange Commission and the New York Stock Exchange.

Each Trust’s Audit Committee appointed the firm of KPMG LLP as the Trust’s independent registered public accountant for the fiscal year ending December 31, 2013, and, in connection therewith, KPMG LLP will prepare all of each Trust’s tax returns for the fiscal year ending December 31, 2013.

February 20, 2013

Each Trust’s Board of Trustees reviewed this Report and approved the audited financial statements for publication in each Trust’s Annual Report.

THE TRUSTS’ INDEPENDENT AUDITORS

KPMG LLP (“KPMG”) audited the financial statements of each Trust, Babson Capital, and MassMutual for the fiscal year ended December 31, 2012. KPMG’s audit report for each Trust contained no qualifications or modifications. A KPMG representative is expected to be present at the upcoming Annual Meeting. This representative shall have the opportunity to make a statement if he or she desires to do so, and it is expected that such representative will be available to respond to appropriate questions from shareholders. As noted above, KPMG will audit each Trust’s 2013 financial statements and prepare each Trust’s 2013 Federal and state tax returns.

The category “Audit-Related Fees” reflects fees billed by KPMG for various non-audit and non-tax services rendered to the Trusts, Babson Capital and MassMutual, such as SAS 70 review, IFRS consulting and agreed upon procedures reports. Preparation of Federal, state and local income tax returns and tax compliance work are representative of the fees reported in the “Tax Fees” category. The category “All Other Fees” represents fees billed by KPMG for consulting rendered to Babson Capital and MassMutual. The Sarbanes-Oxley Act of 2002 and its implementing regulations allows each Trust’s Audit Committee to establish a pre-approval policy for certain services rendered by the Trust’s independent accountants. During 2012, each Trust’s Audit Committee approved all of the services rendered to the Trust by KPMG and did not rely on such a pre-approval policy for any such services.

The 2011 fees billed represent final 2011 amounts, which may differ from the preliminary figures available as of the publication date of the Trusts’ 2012 Proxy Statement and includes, among other things, fees for services that may not have been billed as of the publication date of the Trusts’ 2012 Proxy Statement, but are now properly included in the 2011 fees billed to each Trust, Babson Capital and MassMutual.

OTHER BUSINESS

The Board of Trustees of each Trust knows of no business to be brought before the Meeting other than as set forth above. If, however, any other matters properly come before the Meeting, it is the intention of the persons named in the enclosed proxy card to vote proxies on such matters in accordance with their best judgment.

INFORMATION ABOUT VOTING PROXIES AND THE MEETING

Manner of Voting Proxies

Votes cast by proxy or in person at the Meeting will be counted by persons appointed by each Trust to act as election inspectors for the Meeting. The election inspectors will count the total number of votes cast “for” approval of the Proposals for purposes of determining whether sufficient affirmative votes have been cast. All proxies received, including proxies that reflect (i) broker non-votes (i.e., shares held by brokers or nominees as to which (a) instructions have not been received from the beneficial owners or the persons entitled to vote, and (b) the broker or nominee does not have discretionary voting power on a particular matter), (ii) abstentions or (iii) the withholding of authority to vote for a nominee for election as Trustee, will be counted as shares that are present on a particular matter for purposes of determining the presence of a quorum. The presence at the Meeting, in person or by proxy, of shareholders entitled to cast a majority of the votes shall be a quorum for the transaction of business for each Proposal. With respect to Proposal 1, neither abstentions nor broker non-votes, if any, will have an effect on the outcome of Proposal 1. With respect to Proposal 2, abstentions and broker non-votes, if any, will have the effect of votes against Proposal 2.

Shareholders of each Trust are entitled to one vote, on each matter on which the shareholder is entitled to vote, for each share of the Trust that such shareholder owns at the close of business on February 19, 2013. Each fractional share is entitled to a proportionate fractional vote.

Instructions for Voting Proxies

The giving of a proxy will not affect a shareholder’s right to vote in person should the shareholder decide to attend the Meeting. To vote by mail, please mark, sign, date and return the enclosed proxy card(s) following the instructions printed on the card. Please refer to your proxy card(s) for instructions for voting by telephone or internet.

Revocation of Proxies

Any person giving a proxy has the power to revoke it by mail or in person at any time prior to its exercise by executing a superseding proxy or by submitting a notice of revocation to the Trust. All properly executed and unrevoked proxies received in time for the Meeting will be voted in accordance with the instructions contained therein.

Adjournment

If sufficient votes in favor of any of the proposals set forth in the Notice of Joint Annual Meeting of Shareholders are not received by the time scheduled for the Meeting or if the quorum required for a proposal has not been met, the persons named as proxies may propose adjournments of the Meeting with respect to such proposal(s) for periods of not more than 120 days to permit further solicitation of proxies. Any adjournment will require the affirmative vote of a majority of the votes cast on the proposal in person or by proxy at the session of the Meeting to be adjourned. The persons named as proxies will vote in favor of adjournment those proxies that they are entitled to vote in favor of the proposal. They will vote against any such adjournment those proxies required to be voted against the proposal. The Trusts will pay the costs of any additional solicitation and of any adjourned session. Any proposals for which sufficient affirmative votes have been received by the time of the Meeting may be acted upon and considered final regardless of whether the Meeting is adjourned to permit additional solicitation with respect to any other proposal.

Based solely on a review of these forms furnished to the Trusts as well as certain internal documents, each Trust believes that its Trustees and relevant officers, Babson Capital, and its relevant affiliated persons have all complied with applicable filing requirements during each Trust’s fiscal year ended December 31, 2012 with the exception of William J.

PROPOSALS BY SHAREHOLDERS AND COMMUNICATIONS WITH

THE BOARD OF TRUSTEES

Any shareholder intending to present a proposal at the Annual Meeting to be held in 2014 who wishes to have such proposal included in the Trust’s proxy material for that meeting, should forward his/her written proposal to the Trust, Attention: Secretary. Proposals must be received on or before November 12, 2013, to be considered for inclusion in the Trust’s proxy material for its 2014 Annual Meeting.

Pursuant to procedures approved by each Trust’s Board of Trustees, including a majority of the Trustees who are not “interested persons” of the Trust as defined in Section 2(a)(19) of the 1940 Act, shareholders may mail written communications to the Board of Trustees by writing the Trust’s Chief Financial Officer at the office of the Trust’s investment adviser or by emailing the respective Trust’s Chief Financial Officer at mcimailbox@massmutual.com or mpvmailbox@massmutual.com. When writing to a Trust’s Board of Trustees, shareholders should identify themselves, the fact that the communication is directed to the Board of Trustees, and any relevant information regarding their Trust holdings.

ADDITIONAL INFORMATION

Proxies will be solicited by mail and may be solicited in person or by telephone, electronically, or facsimile by officers of each Trust. The expenses connected with the solicitation of these proxies and with any further proxies which may be solicited by each Trust’s officers in person, by telephone, or by facsimile will be borne by each respective Trust. The Trusts have engaged Broadridge to provide shareholder meeting services, including vote solicitation and tracking. It is anticipated that the cost of these services will be approximately $64,000 for the Trusts and may increase in the event any vote is contested or increased solicitation efforts are required. The Trusts will reimburse banks, brokers, and other persons holding each respective Trust’s shares registered in their names or in the names of their nominees, for their expenses incurred in sending proxy material to and obtaining proxies from the beneficial owners of such shares, which reimbursement will not be submitted to a vote of each respective Trust’s shareholders.

Each Trust will arrange for at least one Trustee to attend its 2013 Annual Meeting of Shareholders; will encourage all of its Trustees to attend its Annual Meetings of Shareholders; and will endeavor to arrange Annual Meetings of Shareholders on the same date as a Board of Trustees meeting to facilitate Trustee attendance. Five of the Trusts’ Trustees attended the April 27, 2012 Annual Meeting.
