MUTUAL OF AMERICA LIFE INSURANCE COMPANY

Mutual of America Investment Corporation

Short-Term Bond Fund

320 Park Avenue, New York, New York 10022

March , 2006

Dear Variable Annuity Contract or

Variable Life Insurance Policy Owner:

Shares of the Short-Term Bond Fund (the “Short-Term Bond Fund”) of Mutual of America Investment Corporation (“MOA”) have been purchased at your direction by the Mutual of America Life Insurance Company (the “Insurance Company”) through one or more of its separate accounts to fund benefits payable under your variable annuity contract or variable life insurance policy (collectively, the “variable contracts”). The Insurance Company, as the shareholder of record and legal owner of those separate accounts, has been asked to approve an Agreement and Plan of Reorganization (the “Plan”) whereby the Short-Term Bond Fund will be merged with and into the Mid-Term Bond Fund, a series in the Investment Company, (the “Mid-Term Bond Fund” and together with the Short-Term Bond Fund, the “Funds”) in a tax-free reorganization. As an owner of a variable contract with an interest in one or more of those separate accounts, MOA is asking you for instructions as to how to vote the shares of the Short-Term Bond Fund that are attributable to your variable contract.

If the Plan is approved and consummated, the separate account(s) in which you have an interest will own shares of the Mid-Term Bond Fund instead of shares of the Short-Term Bond Fund. Each separate account will receive shares of the Mid-Term Bond Fund with an aggregate net asset value equal to the aggregate net asset value of the shares of the Short-Term Bond Fund owned by the separate account before the reorganization.

Here are some facts about the reorganization and the Mid-Term Bond Fund that will be useful to you as you vote on this reorganization:

Following the reorganization, the Mid-Term Bond Fund is expected to have an aggregate operating expense ratio that is no higher than that of the Short-Term Bond Fund currently; however, since all non-advisory fee operating expenses have been contractually waived until April 30, 2006, there will be no immediate reduction in the non-advisory fee operating expenses assessed against your contract.

Your Vote is Important!

2.	You may transfer all or a part of your interest in the Mid-Term Bond Fund as provided in your contract to another available investment option on each day the Mid-Term Bond Fund is open for business at the then current net asset value per share.

Mutual of America Capital Management Corporation (“Capital Management”) is the investment adviser for the Funds. Capital Management is a subsidiary of MOA. Management of the Investment Company has proposed this reorganization in order to (1) eliminate a Fund that is relatively small in size, and, except for its duration, very similar in its investment objective to the Mid-Term Bond Fund, (2) combine that Fund into the Mid-Term Bond Fund which is managed by essentially the same team of portfolio managers, in order to enhance investment efficiency and to attempt to take best advantage of the portfolio management team’s expertise, and (3) generate economies of scale (and thereby lower expense ratios in the future).

After carefully considering the merits of the proposal, the Investment Company’s Board of Directors (the “Board”) has determined that the reorganization is in the best interests of each Fund’s shareholders, and indirectly in the best interests of the underlying contract owners of the Funds, and that the shareholders’ interests will not be diluted as a result of the reorganization.

The Mid-Term Bond Fund, which is available to your variable contract as an investment option, offers a portfolio with investment objectives and policies that are similar to those of the Short-Term Bond Fund, although there are some important differences. The Board anticipates that combining the assets of the Funds should result in more efficient mutual fund operations due to the increased size of the surviving Fund, which, in turn, should result in economies of scale that benefit investors.

The Board recommends that you read the enclosed materials carefully and then instruct MOA to vote FOR the proposal. Please take a moment now to sign and return the voting instruction form(s) in the enclosed postage-paid envelope. For more information, please call MOA at 1-800-468-3785.

Yours truly,

Mutual of America Life Insurance Company

We urge you to sign and return the voting instruction form(s) in the enclosed postage-paid envelope.

INTRODUCTION

This Combined Prospectus/Proxy Statement is being furnished to solicit the voting instructions of variable contract owners whose variable contracts are funded by the Insurance Companies’ separate accounts that invest in the Short-Term Bond Fund, a series of the Investment Company. Such voting instructions will be followed by the Insurance Companies, as the record owner of all of the Short-Term Bond Fund’s shares, at the Meeting, to be held on April 26, 2006 at 9:00 a.m. (Eastern time) at the Investment Company’s offices at 320 Park Avenue, New York, New York 10022. It is expected that this Combined Prospectus/Proxy Statement will be mailed on or about March 17, 2006.

At the Meeting, shareholders will consider and approve or disapprove the Reorganization Plan of the Investment Company on behalf of its series the Short-Term Bond Fund. If the Reorganization Plan is approved, the Short-Term Bond Fund’s shareholders will become shareholders of the Mid-Term Bond Fund and will receive shares of the Mid-Term Bond Fund equal in value to their holdings in the Short-Term Bond Fund on the date of the Reorganization.

THE BOARD OF DIRECTORS OF THE INVESTMENT COMPANY UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE “FOR” THE REORGANIZATION PLAN.

SUMMARY

The following is a summary of certain information relating to the proposed Reorganization, the parties thereto, and the transactions contemplated thereby. This disclosure is qualified by reference to the more complete information contained elsewhere in this Combined Prospectus/Proxy Statement, the Reorganization Plan attached to this Combined Prospectus/Proxy Statement as Appendix A, the Mid-Term Bond Fund Prospectus attached as Appendix B, and the Short-Term Bond Fund Prospectus and Statement of Additional Information for the Investment Company.

Pursuant to the proposed Reorganization Plan, the Short-Term Bond Fund will transfer substantially all of its assets and all of its liabilities to the Mid-Term Bond Fund in exchange for shares of the Mid-Term Bond Fund, a series of the Investment Company.

The proposed Reorganization is expected to be effective upon the opening of business on August 1, 2006 or such later date as the parties may agree (the “effective date”). Under the proposed Reorganization, each shareholder of the Short-Term Bond Fund will receive the number of the Mid-Term Bond Fund’s shares with an aggregate net asset value equal on the effective date to the aggregate net asset value of the shareholder’s shares in the Short-Term Bond Fund. Thereafter, following the proposed Reorganization, shareholders of the Short-Term Bond Fund will be shareholders of the Mid-Term Bond Fund. No shareholder of the Short-Term Bond Fund will pay a sales or other charge or expense in connection with the Reorganization. Also, there will not be any adverse tax consequences for the variable contract owners. See “Information Relating to the Proposed Reorganization.”

Following the Reorganization, the Mid-Term Bond Fund will have identical purchase, redemption and dividend policies as the Short-Term Bond Fund.

Reasons for the Reorganization

- 4 -

The Board, including a majority of the Board’s members who are not “interested persons” within the meaning of the 1940 Act (the “disinterested Board members”), has determined that the proposed Reorganization is in the best interests of the applicable Fund’s respective shareholders and the underlying contract owners and that the interests of the shareholders and contract owners will not be diluted as a result of Reorganization. In connection with making these determinations, the Board was provided with information regarding the size of the Short-Term Bond Fund, which could make it difficult for the Fund to continue to attract contract owner assets. The Board was also provided with information on the similarities in the management of the Short-Term Bond Fund and the Mid-Term Bond Fund, including similarities in investment style and policies, management team, and fund expenses. In the view of fund management and in light of the above factors, there is no substantial need to maintain the Funds as two separate investment portfolios, and the combination of the Funds would enable the surviving Fund to operate more efficiently and achieve certain economies of scale that accompany a larger fund. Furthermore, shareholders who wish to achieve an overall investment strategy similar to that of the Short-Term Bond Fund (investment in debt securities with relatively short maturities, with current income as an investment objective) may allocate their investments between the Mid-Term Bond Fund and the Money Market Fund of the Investment Company.

Federal Income Tax Consequences

Sutherland Asbill & Brennan LLP, special tax counsel to the Investment Company, will issue an opinion (based on certain representations) as of the effective date of the Reorganization to the effect that the transaction will not give rise to the recognition of income, gain or loss for federal income tax purposes to the Short-Term Bond Fund, the Mid-Term Bond Fund or their respective shareholders. The holding period and tax basis of shares received in the transaction by the shareholders of the Short-Term Bond Fund will be the same as the holding period and tax basis of the shareholders’ shares of the Short-Term Bond Fund immediately prior to the Reorganization. In addition, the holding period and tax basis of assets that are transferred to the Mid-Term Bond Fund will be identical in the hands of the Mid-Term Bond Fund to the holding period and tax basis in the hands of the Short-Term Bond Fund immediately prior to the Reorganization. Also, the contract owners will not recognize any gain or loss as a result of the Reorganization. See “Information Relating to the Proposed Reorganization - Federal Income Tax Consequences” below.

Investment Adviser

The investment adviser for the Funds is Mutual of America Capital Management Corporation (“Capital Management” or the “Adviser”), an indirect wholly-owned subsidiary of MOA. After the Reorganization, the same portfolio management team that currently is responsible for the Mid-Term Bond Fund, each member of which is also part of management team responsible for the Short-Term Bond Fund, will continue to make the day-to-day investment decisions for the Mid-Term Bond Fund.

Investment Objectives and Approaches

The Short-Term Bond Fund and the Mid-Term Bond Fund each has an investment objective of seeking current income, with preservation of shareholders’ capital a secondary objective. However, the average maturity of the securities holdings of the Short-Term Bond Fund is one to three years while the average maturity of the securities holdings of the Mid-Term Bond Fund is three to seven years.

- 5 -

While the approaches each Fund uses to seek to achieve its objective are similar, there are certain differences in these approaches that should be considered. The following table sets forth the principal investment approach of the Short-Term Bond Fund and the Mid-Term Bond Fund.

	Investment Approach
Short-Term Bond Fund	Invests primarily in publicly-traded, investment-grade debt securities, and in corporate, U.S. Government securities and U.S. Government agency securities and money market instruments, such as bonds, notes, mortgage-backed securities and commercial paper. May have a significant portion of its assets in a particular debt security, such as U.S. Government or agency securities, which also may be mortgage-backed securities.
Mid-Term Bond Fund	Invests primarily in publicly-traded, investment-grade debt securities, and in corporate, U.S. Government securities and U.S. Government agency securities, such as bonds, notes, debentures, zero coupon securities and mortgage-backed securities. May have a significant portion of its assets in a particular debt security, such as U.S. Government agency securities, zero coupon securities or securities rated BBB or higher.

Investment Policies and Restrictions

In addition to the similarities and differences between the investment objectives and principal investment approach of the Mid-Term Bond Fund and the Short-Term Bond Fund, there are certain similarities and differences in the other investment policies and investment restrictions of the Funds, which are discussed below under “Comparison of Investment Objectives and Policies.”

RISK FACTORS

The following discussion highlights the principal risk factors associated with an investment in the Mid-Term Bond Fund and compares those risks with those of an investment in the Short-Term Bond Fund. Further information relating to these and other risks is set forth in “Comparison of Investment Objectives and Policies” below. This discussion is qualified in its entirety by the more extensive discussion of risk factors set forth in the prospectus and statement of additional information of the Mid-Term Bond Fund.

The Mid-Term Bond Fund and the Short-Term Bond Fund are both subject to market risk and credit risk. Market risk for investments in bond funds includes changes in the overall level of interest rates. Interest rate increases usually cause a decline in the value of debt securities, with the amount of the decline greater for securities with longer terms to maturity. For this reason, the Mid-Term Bond Fund has more market risk than the Short-Term Bond Fund.

Investment grade debt securities with lower ratings (such as BBB), which the Mid-Term Bond Fund may purchase, may be subject to a greater market risk than higher-rated securities. Below

- 6 -

investment-grade securities (rated below BBB), which the Mid-Term Bond Fund may hold, are subject to greater market risk than investment grade debt securities. Zero coupon securities, which the Mid-Term Bond Fund also may purchase, may be subject to a greater market risk than securities that pay interest on a regular basis. Mortgage-backed securities or certificates, which the Mid-Term Bond Fund and the Short-Term Bond Fund may purchase, and in which the Short-Term Bond Fund from time to time invests a significant portion of its assets, are subject to prepayment risk (shortening the term to maturity) when interest rates fall and to extension risk (lengthening the term to maturity) when interest rates rise. Credit risk for investments in bond funds refers to the ability of the issuer of a security to pay principal and interest as it becomes due. Securities rated BBB or lower generally have more credit risk than higher-rated securities. The overall risk level of the Short-Term Bond Fund may be less than that of the Mid-Term Bond Fund since it invests in securities with shorter maturities.

COMPARATIVE FEE AND EXPENSE TABLES

The table below shows (1) information regarding the fees and expenses paid by each of the Short-Term Bond Fund and the Mid-Term Bond Fund for the year ended December 31, 2005, and (2) estimated fees and expenses on a pro forma basis for the Mid-Term Bond Fund after giving effect to the proposed Reorganization with the Short-Term Bond Fund. The fees and charges reflected in the tables and in the example below do not include fees and charges imposed by the variable contracts issued by the Insurance Company and their separate accounts with interests in the Funds.

	Short-Term Bond Fund	Mid-Term Bond Fund	Mid-Term Bond Fund (pro forma with the Short- Term Bond Fund)
Shareholder Fees (fees paid directly from your investment)	N/A	N/A	N/A
Annual Fund Operating Expenses (expenses that are deducted from Fund assets)
Management Fees	0.50%	0.50%	0.50%
Distribution (12b-1) Fees	NONE	NONE	NONE
Other Expenses*	%	%	%
Total Annual Fund Operating Expenses	%	%	%

* Capital Management had contractually agreed beginning as of January 1, 2003 to limit each Fund’s total operating expenses (excluding taxes, brokerage commissions, extraordinary expenses and other fees related to portfolio transactions) to its investment management fees. Capital Management had voluntarily limited the Funds’ expenses since the inception of each Fund, prior to providing the contractual expense limitation commencing January 1, 2003. This contractual obligation remained in effect for the year 2005 and, as a result of the Capital Management’s written notice of termination under the terms of the Agreement as amended, it will continue until midnight on April 30, 2006 at which time it will terminate. After the termination takes effect, the Investment Company will no longer be reimbursed by Capital Management for any of its expenses.

Example: This example helps investors compare the cost of investing in the Funds with the cost of investing in other mutual funds. The example assumes:

•	you invest $10,000;
•	you sell all of your shares at the end of the period;
•	your investment has a 5% return each year; and
•	each Fund’s operating expenses remain the same as shown above.

Although actual costs may be higher or lower, based upon these assumptions your costs would be:

INFORMATION RELATING TO THE PROPOSED REORGANIZATION

General

The Reorganization Plan sets forth the terms and conditions under which the Reorganization would be consummated. Significant provisions of the Reorganization Plan are summarized below; however, this summary is qualified in its entirety by reference to the copy of the Reorganization Plan attached as Appendix A to this Combined Prospectus/Proxy Statement and is incorporated herein by reference.

Description of the Reorganization Plan

The Reorganization Plan provides that at the closing substantially all (other than cash in an amount necessary to pay dividends and distributions as provided in the Reorganization Plan) of the assets and all of the liabilities of the Short-Term Bond Fund will be transferred to and assumed by the Mid-Term Bond Fund. In exchange for the transfer of the assets and the assumption of the liabilities, the Investment Company will issue at the closing full and fractional shares of the Mid-Term Bond Fund equal in aggregate dollar value to the aggregate net asset value of full and fractional outstanding shares of the Short-Term Bond Fund as determined at the valuation time specified in the Reorganization Plan. The Reorganization Plan provides that the Short-Term Bond Fund will declare a dividend or dividends and/or other distributions on or as soon as practicable prior to the Closing Date (as defined in the Reorganization Plan) which will have the effect of distributing to shareholders all of its investment company taxable income (computed without regard to any deduction for dividends paid) and realized net capital gain, if any, for the current taxable year through the Closing Date.

Following the transfer of assets to, and the assumption of the liabilities of, the Short-Term Bond Fund by the Mid-Term Bond Fund, the Short-Term Bond Fund will distribute the Mid-Term Bond Fund shares in liquidation of the Short-Term Bond Fund. Each Short-Term Bond Fund shareholder at the Closing Date will receive an amount of shares with a total net asset value equal to the net asset value of their Short-Term Bond Fund shares plus the right to receive any dividends or distributions that were

- 8 -

declared before the Closing Date but that remained unpaid at that time with respect to the Short-Term Bond Fund shares.

After the Reorganization, all of the issued and outstanding shares of the Short-Term Bond Fund shall be canceled on the books of the Fund and the transfer books of the Short-Term Bond Fund will be permanently closed.

The Reorganization is subject to a number of conditions, including, without limitation: approval of the Reorganization Plan and the transactions contemplated thereby described in this Combined Prospectus/Proxy Statement by the Short-Term Bond Fund shareholders; the receipt of a legal opinion from special tax counsel to the Investment Company with respect to certain tax issues, as more fully described in “Federal Income Tax Consequences” below; and the parties’ performance of their respective agreements and undertakings in the Reorganization Plan. Assuming satisfaction of the conditions in the Reorganization Plan, the Closing Date will be August 1, 2006 or such other date as is agreed to by management.

MOA or Capital Management will bear the costs and expenses associated with the Reorganization, including costs of soliciting proxies.

Board Considerations

In approving the Reorganization at a meeting held on February 24, 2005, the Board considered the proposed Reorganization from the perspective of both of the Funds. In light of discussions of the Board regarding the Short-Term Bond Fund at the February, 2005 meeting, the Board, including a majority of the disinterested Directors, unanimously decided to approve the Reorganization and to recommend its approval to shareholders.

>From the perspective of the Short-Term Bond Fund, the Board considered the relatively small size of the Fund, and the conclusion of Investment Company management that the Fund’s prospects for attracting substantial additional amounts of policy owner assets were limited. The Board also considered the similarities between the Short-Term Bond Fund and the Mid-Term Bond Fund. It considered that the Funds have, except for the average maturity of the securities holdings, identical investment objectives and similar investment policies. It also considered that each member of the Mid-Term Bond Fund’s portfolio management team currently is also a member of the management team of the Short-Term Bond Fund. It considered that the management fee for the Mid-Term Bond Fund after the Reorganization would be the same as the current management fee for the Short-Term Bond Fund, and that merger of the Short-Term Bond Fund into the Mid-Term Bond Fund would enable the combined Fund to operate more efficiently and achieve certain economies of scale that accompany a larger fund, resulting in lower operating expenses as compared to the existing the Short-Term Bond Fund. The Board also considered the terms of the Reorganization Plan, and the fact that the Reorganization would constitute a tax-free reorganization.

From the perspective of the Mid-Term Bond Fund, the Board considered, among other things: the terms of the Reorganization Plan; the opportunity to combine the Funds in an effort to realize operational and administrative efficiencies; the terms of the Reorganization Plan; and the fact that the Reorganization would constitute a tax-free reorganization.

After considering the foregoing factors, together with such information as they believed to be relevant, the Board determined that the proposed Reorganization is in the best interests of each Fund, and that the interests of each Fund’s shareholders and, indirectly, the contract owners, would not be

- 9 -

diluted as a result of the Reorganization. The Board then approved the Reorganization Plan and directed that the Reorganization Plan be submitted to the Short-Term Bond Fund shareholders for approval.

Therefore, the Investment Company’s Board of Directors unanimously recommends that Shareholders vote “FOR” the Proposal.

The Board has not determined what action the Short-Term Bond Fund would take in the event shareholders fail to approve the Reorganization Plan or for any reason the Reorganization is not consummated. In any such event, the Short-Term Bond Fund will, at least for a period of time, continue operations as a separate series of the Investment Company, and the Board of Directors may consider alternatives to the Reorganization in the best interests of shareholders.

Certain Arrangements with Service Providers

Advisory Services

Capital Management is the investment adviser for both the Mid-Term Bond Fund and the Short-Term Bond Fund. Capital Management provides investment advice and, in general, supervises the management and investment program for each of the Funds. As compensation for its services, Capital Management receives a management fee from the Mid-Term Bond Fund at the annual rate of 0.50% of the average daily net assets of the Mid-Term Bond Fund. As compensation for its services, Capital Management receives a management fee from the Short-Term Bond Fund at the annual rate of 0.50% of the average daily net assets of the Short-Term Bond Fund.

After the Reorganization, the Mid-Term Bond Fund will pay management fees at a rate that is the same as the rate currently paid by the Short-Term Bond Fund. Furthermore, because of economies of scale that will result from the Reorganization, it is expected that the expenses of the Mid-Term Bond Fund, other than the management fee, and its overall expense ratio will be lower after the Reorganization than the current expenses of the Short-Term Bond Fund. Capital Management has contractually agreed to reimburse the Investment Company for certain operating expenses through April 30, 2006, at which time the Funds will no longer be reimbursed for such expenses. After the termination of expense reimbursement take effect, it is anticipated that the operating expenses of the Mid-Term Bond Fund after the reorganization will be no higher than those of the Short-Term Bond Fund.

Other Services

After the Reorganization, shares of the Mid-Term Bond Fund will continue to be offered to the separate accounts of the Insurance Companies that originally held shares in the Short-Term Bond Fund.

After the Reorganization, the service providers for the Mid-Term Bond Fund will remain the same. MOA will serve as the transfer agent. MOA will also provide certain recordkeeping, accounting services, pricing and bookkeeping services. After the Reorganization, JPMorgan Chase Bank, 1285 Avenue of the Americas, New York, New York 10019, will continue as the custodian for the Mid-Term Bond Fund.

FEDERAL INCOME TAX CONSEQUENCES

- 10 -

Consummation of the Reorganization is subject to the condition that the Investment Company receive an opinion of Sutherland Asbill & Brennan, special tax counsel to the Investment Company, to the effect that for federal income tax purposes:

1.	the transfer to the Mid-Term Bond Fund of all or substantially all of the assets of the Short-Term Bond Fund in exchange solely for shares of the Mid-Term Bond Fund and the assumption by the Mid-Term Bond Fund of all of the liabilities of the Short-Term Bond Fund, followed by the distribution of the Mid-Term Bond Fund Shares to the holders of shares of the Short-Term Bond Fund in exchange for their shares of the Short-Term Bond Fund in complete liquidation of the Short-Term Bond Fund, will constitute a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code (the “Code”), and the Mid-Term Bond Fund and the Short-Term Bond Fund will each be “a party to a reorganization” within the meaning of Section 368(b) of the Code;
2.	no gain or loss will be recognized by the Short-Term Bond Fund upon the transfer of the Short-Term Bond Fund’s assets to the Mid-Term Bond Fund solely in exchange for the Mid-Term Bond Fund Shares and the assumption by the Mid-Term Bond Fund of liabilities of the Short-Term Bond Fund or upon the distribution of the Mid-Term Bond Fund Shares to the shareholders of the Short Term Bond Fund.
3.	the Mid-Term Bond Fund’s basis in the assets and liabilities received from the Short-Term Bond Fund will be the same as the Short-Term Bond Fund’s basis in such assets and liabilities immediately prior to the transfer;
4.	the Mid-Term Bond Fund’s holding period for the transferred assets will include the period during which such assets were held by the Short-Term Bond Fund;
5.	no gain or loss will be recognized by the Mid-Term Bond Fund upon the receipt of the assets of the Short-Term Bond Fund in exchange for shares of the Mid-Term Bond Fund and the assumption by the Mid-Term Bond Fund of the liabilities of the Short-Term Bond Fund;
6.	no gain or loss will be recognized by the shareholders of the Short-Term Bond Fund on the exchange of their shares of the Short-Term Bond Fund solely for shares of the Mid-Term Bond Fund;
7.	a Short-Term Bond Fund shareholder’s basis in the Mid-Term Bond Fund shares received in the Reorganization will be the same as the adjusted basis of the shares of the Short-Term Bond Fund exchanged therefor;
8.	a Short-Term Bond Fund shareholder’s holding period in the shares of the Mid-Term Bond Fund received in the Reorganization will include the shareholder’s holding period for the shares of the Short-Term Bond Fund exchanged therefor, provided that such Short-Term Bond Fund shares were held as capital assets on the Closing Date.
9.	the Mid-Term Bond Fund will succeed to and take into account the items of the Short-Term Bond Fund described in Section 381(c) of the Code, including any earnings or profits, or deficit therein, of the Short-Term Bond Fund as of the Closing Date, subject to the conditions and limitations specified in Sections 381, 382, 383 and 384 of the Code; and

- 11 -

10.	no gain or loss will be recognized by contract owners as a result of the Reorganization.

The Investment Company has not sought a tax ruling from the Internal Revenue Service (the “IRS”), but is acting in reliance upon the opinion of counsel discussed in the previous paragraph. That opinion is not binding on the IRS and does not preclude the IRS from adopting a contrary position. Shareholders should consult their own tax advisors concerning their potential tax consequences, including state and local income taxes.

CAPITALIZATION

Because the two Funds will be combined if the Reorganization is consummated, the total capitalization of the Mid-Term Bond Fund after the Reorganization is expected to be greater than the current capitalization of each Fund separately. The following table sets forth as of December 31, 2005: (1) the capitalization of the Short-Term Bond Fund; (2) the capitalization of the Mid-Term Bond Fund; and (3) the pro forma capitalization of the Mid-Term Bond Fund as adjusted to give effect to the proposed Reorganization. The assets and outstanding shares of the Mid-Term Bond Fund and the Short-Term Bond Fund are likely to be different on the Closing Date than was the case on December 31, 2005 as a result of fluctuations in the value of portfolio securities of each Fund and daily share purchase and redemption activity in each Fund.

COMPARISON OF INVESTMENT OBJECTIVES AND POLICIES

The following discussion summarizes some of the investment policies of the Mid-Term Bond Fund, together with the primary differences, if any, from those of the Short-Term Bond Fund.

Investment Objective

The investment objective of the Mid-Term Bond Fund is to seek long-term growth of capital, with an average maturity of its securities holdings of three to seven years. The Short-Term Bond Fund has the same objective except the average maturity is one to three years.

Investment Policies and Restrictions

The investment policies and restrictions of the Mid-Term Bond Fund and the Short-Term Bond Fund are similar.

Neither Fund's investment objective is fundamental. The investment objective and investment policies of either Fund as described above may be changed by the Board without approval of shareholders or holders of variable annuity and variable life insurance contracts. A change in a Fund's investment objective or policies may result in the Fund having a different investment objective or policies from those that a policy owner selected as appropriate at the time of investment. Policy owners with assets allocated to the Mid-Term Bond Fund will be given at least 60 days prior notice of any change in the Mid-Term Bond Fund’s policy of investing at least 80% of its net assets in mid-term

- 12 -

bonds. The fundamental investment restrictions of each Fund, which are set forth in the Investment Company’s Statement of Additional Information, are identical.

MID-TERM BOND FUND FINANCIAL HIGHLIGHTS

Selected data for a share of capital stock outstanding throughout each period

The following financial highlights table is intended to help you understand the Mid-Term Bond Fund's financial performance. Financial highlights for each of the Fund’s last five fiscal years are included in the Prospectus for the Mid-Term Bond Fund enclosed with this Combined Prospectus/Proxy Statement. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in a Fund (assuming reinvestment of all dividends and distributions). The expenses reflected in the table do not reflect any expenses associated with variable contracts such as administrative fees, account charges and surrender charges. If those expenses were included, the expenses shown in the table would be higher and the total returns would be lower. The financial highlights for 2005 have been audited by KPMG LLP, whose report, along with each Fund's financial statements, are included in the annual report, which is available upon request.

SUMMARY OF INFORMATION ABOUT THE INVESTMENT COMPANY GENERALLY

Purchases and Redemptions

The Investment Company offers shares in the Funds only to the Insurance Companies, without sales charge, for allocation to their separate accounts. Acceptance by an Insurance Company of an order for allocating account balance to one of its separate account funds constitutes a purchase order for shares of the corresponding Fund of the Investment Company. In order to comply with Federal laws and regulations to prevent the funding of terrorism and money laundering activities, the Investment Company may refuse to accept funds or issue shares or effect subsequent transactions including accepting additional funds. These actions will be taken on a discretionary basis or when required or compelled to do so by a government authority or applicable law.

The Investment Company redeems all full and fractional shares of the Funds for cash. The redemption price is the net asset value per share next determined. The Investment Company does not imposed any deferred sales charge on redemptions. Redemption proceeds are normally paid within seven days of receipt of the redemption request, unless the Investment Company suspends or delays payment of redemption proceeds as permitted in accordance with SEC regulations. Acceptance by an Insurance Company of an order for withdrawal of account balance from one of the separate account funds constitutes a redemption order for shares of the corresponding Fund of the Investment Company.

Dividends, Distributions and Taxes

Each Fund intends to make distributions of income and capital gains in order to qualify each year as a regulated investment company under Subchapter M of Chapter 1 of the Internal Revenue Code. As a result of qualifying as a regulated investment company, a Fund will not be subject to federal income tax to the extent that the Fund distributes its net investment income and net capital gains. All income and capital gain distributions are automatically reinvested in additional shares of the Fund at net asset value without a sales charge.

Organizational Structure

Each Fund is a series of the Investment Company, a Maryland corporation, and is, therefore, governed by the Investment Company’s Articles of Incorporation, as amended and supplemented from time to time (“Articles of Incorporation”), Bylaws, and by Maryland law. Thus, the following discussion is applicable to each Fund. Additionally, the Investment Company and each Fund are, and will continue to be, governed by the 1940 Act.

The Investment Company has 3.5 billion authorized shares of stock, par value $.01 per share, which may be divided into series and classes. The Articles of Incorporation authorizes the issuance of shares in different series, and authorizes the Board, without further shareholder action, to establish and create additional series and to designate the rights and preferences of the shareholders of each of the respective series. Each Investment Company Fund is a separate series with a separate portfolio of securities, and the shares of each series are preferred over all other series with respect to assets allocated to that series. Each share of a series of the Investment Company represents an equal proportionate interest in that series with each other share of that series. Each series currently has only one class of shares, but may in the future issue multiple classes of shares.

In addition to the Short-Term Bond Fund and the Mid-Term Bond Fund, the Investment Company currently offers 13 other portfolios: the Equity Index, All America, Mid-Cap Equity Index,

- 14 -

Aggressive Equity, Small Cap Growth, Small Cap Value, Mid Cap Value, Composite, Bond, Money Market, Aggressive Allocation, Moderate Allocation, and Conservative Allocation Funds. The Investment Company’s prospectus and statement of additional information include detailed descriptions of each Investment Company Fund. The Investment Company may add or subtract additional Funds from time to time in the future.

The foregoing is only a summary of certain organizational and governing documents and Maryland corporate law. It is not a complete description. Shareholders should refer to the provisions of these documents and state law directly for a more thorough description. Copies of the Articles of Incorporation and Bylaws of the Investment Company are available without charge upon written request.

VOTING INFORMATION

The Insurance Companies are the record owners of all of the shares of the Short-Term Bond Fund. Each Insurance Company will vote the Short-Term Bond Fund’s shares at the Meeting in accordance with the timely instructions received from persons entitled to give voting instructions under its variable contracts. Contract owners and certain annuitants and/or beneficiaries have the right to instruct the Insurance Company that issued the variable contract as to the number of shares (and fractional shares) attributable to their variable contract’s value on the record date allocated to the separate account that holds shares of the Short-Term Bond Fund.

Each Insurance Company will vote shares attributable to its variable contracts as to which no voting instructions are received in the same proportion (for, against, or abstain) to those for which timely instructions are received. In other words, each Insurance Company is entitled to vote shares for which no instructions are received, but will do so in the same proportion as shares for which instructions have been received from contract owners for such insurance company. If a Voting Instruction Form is received that does not provide any instructions, the Insurance Company will consider its timely receipt as an instruction to vote in favor of the proposal. In certain circumstances, the Insurance Company has the right to disregard voting instructions from certain owners. The Insurance Companies do not believe that these circumstances exist with respect to matters currently before shareholders and contract owners. Contract owners may revoke previously submitted voting instructions given to an Insurance Company by notifying the Insurance Company in writing at any time before 5:00 p.m. (Eastern time) on April 25, 2006 or by attending and voting in person at the Meeting. MOA or Capital Management will bear all of the expenses of soliciting voting instructions. The solicitation will be made primarily by mail, but the Insurance Companies and their affiliates may make telephone, electronic, or oral communications to contract owners.

A majority of the outstanding shares of the Short-Term Bond Fund represented in person or by proxy must be present at the Meeting to constitute a quorum. As the record owner of all of the shares of the Short-Term Bond Fund, the Insurance Companies’ presence at the Meeting will be sufficient to constitute a quorum. If a quorum is not present at the Meeting, or if a quorum is present but, at the Meeting, sufficient votes to approve the Reorganization are not received, the persons with proxies may propose one or more adjournments of the Meeting to permit further solicitation of proxies. Any adjournment will require the affirmative vote of a majority of the shares represented at the Meeting in person or by proxy. Based on voting instructions received, proxies will vote in favor of such adjournment those instructions that are in favor of the Reorganization, will vote against any adjournments those instructions that are against the Reorganization, and will abstain from voting with

- 15 -

respect to any adjournment those instructions that are marked to abstain in connection with the Reorganization.

Approval of the Reorganization Plan by the Short-Term Bond Fund shareholders requires the affirmative vote of the holders of the lesser of (a) 67% or more of the voting securities present at the Meeting or represented by proxy if the holders of more than 50% of the outstanding voting securities are present or represented by proxy or (b) more than 50% of the outstanding voting securities of the Short-Term Bond Fund. Shareholders of record are entitled to one vote for each full share owned, with a fractional vote for each fractional share. The Reorganization does not require the approval of the shareholders of the Mid-Term Bond Fund.

The Board has fixed February 24, 2006 as the record date for determining shareholders entitled to receive notice of and to vote at the Meeting. To be counted, an Insurance Company must receive an owner’s properly executed Voting Instruction Form at the Investment Company’s office by 5:00 p.m. Eastern time on April 25, 2006.

The name, address and percentage ownership of the persons who owned beneficially more than 5% of a Fund through any separate accounts of the Insurance Companies invested in the Short-Term Bond Fund, the percentage of such ownership, and the percentage that would be owned by such persons upon consummation of the Reorganization based upon their holdings and the net asset values of the Funds as of the record date are as follows:

Name and Address	Fund	Percentage of Fund Owned on Record Date	Percentage of the Mid-Term Bond Fund Ownership Upon Consummation
None

The Directors and Officers of the Investment Company beneficially owned in the aggregate less than 1% of each Fund. As of the record date, the Insurance Companies owned of record 100% of the outstanding shares of the Mid-Term Bond Fund.

APPENDIX A

PLAN OF REORGANIZATION

THIS PLAN OF REORGANIZATION (the “Plan”) is made as of this __ day of ________, 2006 by Mutual of America Investment Corporation, a Maryland corporation with its principal place of business at 320 Park Avenue, New York, New York 10022 (the “Investment Company”), on behalf of its series, the Short-Term Bond Fund (the “Short-Term Bond Fund” or, at times, the “Merging Fund”) and the Mid-Term Bond Fund (the “Mid-Term Bond Fund” or, at times, the “Acquiring Fund,” and together with the Merging Fund, the “Funds”).

This Plan is intended to be and is adopted as a plan of reorganization and liquidation within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), with respect to each of the Merging Fund and the Acquiring Fund, with which the Merging Fund will reorganize, as provided herein. The reorganization will consist of: (1) the transfer of substantially all of the Merging Fund’s assets to the Acquiring Fund, in exchange solely for shares of beneficial interest (no par value) of the Acquiring Fund (the “Acquiring Fund Shares”); (2) the assumption by the Acquiring Fund of all of the Merging Fund’s liabilities; and (3) the distribution of the Acquiring Fund Shares to the shareholders of the Merging Fund in complete liquidation of such Merging Fund as provided herein, all upon the terms and conditions hereinafter set forth in this Plan (the “Reorganization”).

In order to consummate the Plan, the following actions shall be taken by the Investment Company on behalf of the Merging Fund and the Acquiring Fund:

1.	THE REORGANIZATION

1.1. Subject to the terms and conditions herein set forth and on the basis of the representations and warranties contained herein, the Investment Company, on behalf of the Merging Fund, agrees to transfer to the Acquiring Fund substantially all of the Merging Fund’s assets as set forth in Section 1.2, and the Acquiring Fund agrees in exchange therefor:

(i) to issue and deliver to the Merging Fund the number of full and fractional Acquiring Fund Shares determined by dividing the portion of the net value of the assets (such net value computed as set forth in Section 2.1 hereof and referred to as the “Merging Fund Value”) attributable to the Merging Fund Shares by the net asset value (“NAV”) of an Acquiring Fund Share (computed as set forth in Section 2.2); and

(ii)	to assume all of the liabilities of the Merging Fund, as set forth in Section 1.3.

Such transactions shall take place at the closing provided for in Section 3.1 (the “Closing”).

1.2. The assets of the Merging Fund to be transferred to the Acquiring Fund (collectively, “Assets”) shall consist of all property and assets of every kind and nature of the Merging Fund, including, without limitation, all cash, cash equivalents, securities, commodities, futures, claims (whether absolute or contingent, known or unknown), receivables (including dividend, interest and other receivables), good will and other intangible property, any deferred or prepaid expenses, and all interests, rights, privileges and powers, other than cash in an amount necessary to pay dividends and distributions as provided in Section 1.4 hereof and the Merging Fund’s rights under this Plan.

1.3. The Acquiring Fund shall assume all liabilities of the Merging Fund, whether accrued or contingent, existing at the Valuation Time as defined in Section 2.1. The Merging Fund will endeavor to discharge all of its known liabilities and obligations prior to the Closing Date as defined in Section 3.1, other than those liabilities and obligations which would otherwise be discharged at a later date in the ordinary course of business.

1.4. On or as soon as practicable prior to the Closing Date, the Merging Fund will declare and pay to its shareholders of record one or more dividends and/or other distributions so that it will have distributed substantially

all of its investment company taxable income (computed without regard to any deduction for dividends paid) and realized net capital gain, if any, for the current taxable year through the Closing Date.

1.5. Immediately after the transfer of its assets provided for in Section 1.1, the Merging Fund will distribute to its shareholders of record (the “Merging Fund Shareholders”), determined as of the Valuation Time as defined in Section 2.1, on a pro rata basis, the Acquiring Fund Shares received by the Merging Fund pursuant to Section 1.1 and will completely liquidate. Merging Fund Shareholders owning Merging Fund Shares shall receive Acquiring Fund Shares therefor. Such distribution and liquidation will be accomplished by the transfer of the Acquiring Fund Shares then credited to the account of the Merging Fund on the books of the Acquiring Fund to open accounts on the share records of the Acquiring Fund in the names of the Merging Fund Shareholders. The aggregate net asset value of the Acquiring Fund Shares to be so credited to Merging Fund Shareholders shall be equal to the aggregate net asset value of the Merging Fund Shares owned by such shareholders as of the Valuation Time. All issued and outstanding shares of the Merging Fund will simultaneously be cancelled on the books of the Merging Fund. The Acquiring Fund will not issue certificates representing Acquiring Fund Shares in connection with such exchange.

1.6. Ownership of Acquiring Fund Shares will be shown on the Acquiring Fund’s books. Shares of the Acquiring Fund will be issued in the manner described in the Acquiring Fund’s then-current prospectus and statement of additional information.

1.7. Any reporting responsibility of the Merging 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 Merging Fund or the Investment Company on behalf of the Merging Fund.

1.8. All books and records of the Merging Fund, including all books and records required to be maintained under the Investment Company Act of 1940, as amended (the “1940 Act”), and the rules and regulations thereunder, shall be available to the Acquiring Fund from and after the Closing Date and shall be turned over to the Acquiring Fund as soon as practicable following the Closing Date.

VALUATION

2.1. The value of the Assets and liabilities of the Merging Fund shall be computed as of the close of regular trading on the New York Stock Exchange, Inc. (“NYSE”) on the day immediately preceding the Closing Date (such time and date also being hereinafter called the “Valuation Time”), after the declaration and payment of any dividends and/or other distributions on that date, using the valuation procedures described in the Acquiring Fund’s then-current prospectus and statement of additional information. The Merging Fund Value shall be determined by dividing the value of the Assets of the Merging Fund less the value of the liabilities of the Merging Fund as determined as provided herein.

2.2. The net asset value of Acquiring Fund Shares shall be computed as of the Valuation Time using the valuation procedures set forth in the Acquiring Fund’s then-current prospectus and statement of additional information.

2.3. All computations of value hereunder shall be made in accordance with each Fund’s regular practice as set forth in its prospectus and statement of additional information and the requirements of the 1940 Act, and shall be subject to confirmation by the Investment Company’s Board of Directors and the Investment Company’s independent auditors.

3.	CLOSING AND CLOSING DATE

3.1. The Reorganization Closing contemplated by this Plan shall be August 1, 2006, or such earlier or later date as the parties may agree in writing (the “Closing Date”). All acts taking place at the Closing shall be

deemed to take place simultaneously as of 4:00 p.m., Eastern time, on the Closing Date, unless otherwise agreed to by the parties. The Closing shall be held at the offices of the Insurance Company, 320 Park Avenue, New York, New York 10022, or at such other place and time as the parties may agree.

3.2. The Investment Company shall furnish to the Acquiring Fund a statement of the Merging Fund’s net assets, together with a list of portfolio holdings with values as determined in Section 2.1, all as of the Valuation Time, certified by the Investment Company’s Treasurer.

3.3. The Investment Company, on behalf of the Merging Fund, shall have provided for delivery, as of the Closing, of the Merging Fund’s Assets to the account of the Acquiring Fund at the Acquiring Fund’s custodian, JPMorgan Chase Bank (the “Custodian”). The Merging Fund’s securities and instruments deposited with a securities depository, as defined in the applicable rules adopted under section 17(f), or a futures commission merchant, as defined in Rule 17f-6, each under the 1940 Act, shall be delivered as of the Closing Date by book entry in accordance with the customary practices of such depositories and futures commission merchants and the Merging Fund’s Custodian. The cash to be transferred by the Merging Fund shall be transferred and delivered by the Funds as of the Closing Date for the account of the Acquiring Fund.

3.4. The Investment Company shall instruct Mutual of America Life Insurance Company, the transfer agent of the Merging Fund, to deliver at the Closing its records containing the names and addresses of the Merging Fund Shareholders and the number and percentage ownership (to three decimal places) of outstanding Merging Fund Shares owned by each such shareholder immediately prior to the Closing. The Investment Company on behalf of the Acquiring Fund shall issue and deliver a confirmation evidencing the Acquiring Fund Shares to be credited on the Closing Date to the Merging Fund or provide evidence satisfactory to the Merging Fund that such Acquiring Fund Shares have been credited to the Merging Fund’s accounts on the books of the Acquiring Fund.

3.5. In the event that immediately prior to the Valuation Time: (a) the NYSE or another primary trading market for portfolio securities of the Acquiring Fund or the Merging Fund shall be closed to trading or trading thereupon shall be restricted, or (b) trading or the reporting of trading on the NYSE or elsewhere shall be disrupted so that, in the judgment of the Board of Directors of the Investment Company, accurate appraisal of the value of the net assets with respect to the Acquiring Fund Shares or the Merging Fund Shares is impracticable, the Closing Date shall be postponed until the first business day after the day when trading shall have been fully resumed and reporting shall have been restored.

3.6. At the Closing, each party shall deliver to the other such bills of sale, checks, assumption agreements, assignments, share certificates, if any, receipts or other documents as such other party or its counsel may reasonably request to effect the transactions contemplated by this Plan.

4.	REPRESENTATIONS AND WARRANTIES

4.1. The Investment Company makes the following representations and warranties about the Merging Fund:

(a) The Investment Company is a corporation duly established and validly existing under the laws of the State of Maryland with power under its Articles of Incorporation to own all of its properties and assets and to carry on its business as it is now being conducted. The Merging Fund has been duly established as a series of the Investment Company.

(b) No consent, approval, authorization, or order of any court or governmental authority is required for the consummation by the Investment Company, on behalf of the Merging Fund, of the transactions contemplated herein, except such as may be required under the Securities Act of 1933, as amended (the “1933 Act”), the Securities Exchange Act of 1934 (the “1934 Act”), the 1940 Act, and state securities laws.

(c) The Merging Fund is not, and the execution, delivery and performance of this Plan by the Investment Company on behalf of the Merging Fund will not result, in violation of Maryland law or of the Investment Company’s Articles of Incorporation or By-Laws, or of any agreement, indenture, instrument, contract, lease or other undertaking to which the Investment Company or the Merging Fund is a party or by which any of those entities is bound, nor will the execution, delivery and performance of this Plan by the Investment Company on behalf of the Merging Fund result in the acceleration of any obligation, or the imposition of any penalty, under any agreement, indenture, instrument, contract, lease, judgment or decree to which the Merging Fund is a party or by which it is bound.

(d) To the Investment Company’s knowledge, there is no material litigation or administrative proceeding or investigation of or before any court or governmental body presently pending or threatened against the Merging Fund or any properties or assets held by it. The Investment Company knows of no facts that might form the basis for the institution of such proceedings or which would materially and adversely affect its business, or the business of the Merging Fund, and is not a party to or subject to the provisions of any order, decree or judgment of any court or governmental body which materially and adversely affects its or the Merging Fund’s business or its or the Merging Fund’s ability to consummate the transactions herein contemplated.

(e) The financial statements of the Merging Fund at and for the year ended December 31, 2005, audited by KPMG LLP, independent registered public accounting firm, and at and for the six months ended June 30, 2005, are in accordance with U.S. generally accepted accounting principles (“GAAP”) consistently applied. All of such statements present fairly, in all material respects, the financial position, results of operations, changes in net assets and financial highlights of the Merging Fund as of the dates thereof in accordance with GAAP, and there are no known actual or contingent liabilities of the Merging Fund required to be reflected on a statement of assets and liabilities (including the notes thereto) in accordance with GAAP as of such dates not disclosed therein.

(f) Since December 31, 2005, there has not been any material adverse change in the Merging Fund’s financial condition, assets, liabilities or business other than changes occurring in the ordinary course of business, or any incurrence by the Merging Fund of indebtedness maturing more than one year from the date such indebtedness was incurred except as otherwise disclosed to and accepted in writing by the Acquiring Fund. For purposes of this subsection (f), a decline in net asset value per share of the Merging Fund due to declines in market values of securities in the Merging Fund’s portfolio, the discharge of Merging Fund liabilities, or the redemption of Merging Fund Shares by Merging Fund Shareholders shall not constitute a material adverse change.

(g) At the date hereof and at the Closing Date, all federal and other tax returns and reports of the Merging Fund required by law to have been filed by such dates (including any extensions) have or shall have been filed and are or will be correct in all material respects, and all federal and other taxes shown as due or required to be shown as due on said returns and reports shall have been paid or provision shall have been made for the payment thereof, and, to the best of the Investment Company’s knowledge, no such return is currently under audit and no assessment has been asserted with respect to such returns or reports.

(h) For each taxable year of its operation (including the tax year ending on the Closing Date), the Merging Fund has met the requirements of Subchapter M of the Code for qualification as a regulated investment company and has elected to be treated as such, and has been eligible to and has computed its federal income tax under Section 852 of the Code. At Closing, the Merging Fund will have distributed all of its investment company taxable income and net capital gain (as defined in the Code) that has accrued up to the Closing Date. The authorized capital of the Investment Company consists of an unlimited number of shares of beneficial interest, all without par value, and divided into 15 series.

(i) All issued and outstanding shares of the Merging Fund: (1) have been offered and sold in every state and the District of Columbia in compliance in all material respects with applicable registration requirements of the 1933 Act and state securities laws, (2) are, and on the Closing Date will be, duly and

validly issued and outstanding, fully paid and non-assessable, and (3) will be held at the time of the Closing by the persons and in the amounts set forth in the records of the Merging Fund’s transfer agent, as provided in Section 3.4. There are no outstanding options, warrants or other rights to subscribe for or purchase any Merging Fund Shares, nor is there outstanding any security convertible into any Merging Fund Share.

(j) At the Closing Date, the Investment Company, on behalf of the Merging Fund, will have good and marketable title to the Merging Fund’s Assets and full right, power and authority to sell, assign, transfer and deliver such Assets hereunder free of any liens or other encumbrances, except those liens or encumbrances as to which the Investment Company, on behalf of the Acquiring Fund, has received notice at or prior to the Closing, and upon delivery and payment for such Assets, the Acquiring Fund will acquire good and marketable title thereto, subject to no restrictions on the full transfer thereof, except those restrictions as to which the Investment Company, on behalf of the Acquiring Fund, has received notice and necessary documentation at or prior to the Closing.

(k) The current prospectus and statement of additional information of the Merging Fund conform in all material respects to the applicable requirements of the 1933 Act and the 1940 Act and the rules and regulations of the Commission thereunder, and do not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not materially misleading.

(l) The Registration Statement referred to in Section 5.5, insofar as it relates to the Merging Fund, will, on the effective date of the Registration Statement and on the Closing Date, not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which such statements are made, not materially misleading.

(m) As promptly as practicable, but in any case with sixty (60) days after the Closing Date, the Merging Fund will furnish to the Acquiring Fund, in such form as is reasonably satisfactory to the Acquiring Fund, a statement of the earnings and profits of the Merging Fund for federal income tax purposes, as well as any net operating loss carryovers and capital loss carryovers, that will be carried over by the Acquiring Fund as a result of Section 381 of The Code, and which will be certified by the Treasurer of the Merging Fund.

(d) To the Investment Company’s knowledge, there is no material litigation or administrative proceeding or investigation of or before any court or governmental body presently pending or threatened against the Acquiring Fund or any properties or assets held by it.

For purposes of this subsection (f), a decline in net asset value per share of the Acquiring Fund due to declines in market values of securities in the Acquiring Fund’s portfolio, the discharge of Acquiring Fund liabilities, or the redemption of Acquiring Fund Shares by Acquiring Fund shareholders shall not constitute a material adverse change.

(g) At the date hereof and at the Closing Date, all federal and other tax returns and reports of the Acquiring Fund required by law to have been filed by such dates (including any extensions) have or shall have been filed and are or will be correct in all material respects, and all federal and other taxes shown as due or required to be shown as due on said returns and reports shall have been paid or provision shall have been made for the payment thereof, and, to the best of the Investment Company’s knowledge, no such return is currently under audit and no assessment has been asserted with respect to such returns or reports.

(h) For each taxable year of its operation, the Acquiring Fund has met the requirements of Subchapter M of the Code for qualification as a regulated investment company and has elected to be treated as such, has been eligible to and has computed its federal income tax under Section 852 of the Code, and intends to do so for the taxable year including the Closing Date.

(i) All issued and outstanding shares of the Acquiring Fund: (1) have been offered and sold in every state and the District of Columbia in compliance in all material respects with applicable registration requirements of the 1933 Act and state securities laws, and (2) are, and on the Closing Date will be, duly and validly issued and outstanding, fully paid and non-assessable.

Part C – Other Information

Item 15. Indemnification.

Provisions for the indemnification of the Investment Company's Directors and officers are contained in Article X of the Investment Company's Articles of Incorporation and Article VII of the Bylaws.

Registrant’s directors and officers are insured against certain expenses in connection with the defense of claims, demands, actions, suits, or proceedings, and certain liabilities that might be imposed as a result of such actions, suits or proceedings.

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended (the “1933 Act”), may be permitted to directors, trustees, officers and controlling persons of the Registrant and the principal underwriter pursuant to the foregoing provisions or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the 1933 Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, trustee, officer, or controlling person of the Registrant and the principal underwriter in connection with the successful defense of any action, suit or proceeding) is asserted against the Registrant by such director, trustee, officer or controlling person or principal underwriter in connection with the shares being registered, the 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 1933 Act and will be governed by the final adjudication of such issue.
