RISK/RETURN SUMMARY

Investment Goal: Needham Aggressive Growth Fund (the "Fund") seeks long- term capital appreciation by

                                    investing  primarily  in  equities of public
                                    companies    with   strong,    above-average
                                    prospective long-term growth rates.

Principal Investment Strategy:      Under  normal  market  conditions,  the Fund
                                    invests at least 65% of its total  assets in
                                    equity securities of domestic issuers listed
                                    on  a   nationally   recognized   securities
                                    exchange or traded on the Nasdaq System. The
                                    Fund will invest, in general, in markets and
                                    industries  with  strong  growth  potential,
                                    focusing  primarily on the market leaders in
                                    these areas as these  companies often garner
                                    a  disproportionate  share  of the  positive
                                    financial returns. In the intermediate term,
                                    the   Fund   will   focus   on   healthcare,
                                    technology,  business and consumer services,
                                    media, communications,  financial and energy
                                    companies.

Principal Investment Risks:         The  Fund   invests   primarily   in  equity
                                    securities,   which   fluctuate   in  value.
                                    Political  and economic  news can  influence
                                    marketwide  trends.  Other factors may cause
                                    price swings in a single  company's stock or
                                    the stocks of the  companies  within a given
                                    industry.   In  addition,   the  Fund  often
                                    invests   in  smaller   companies.   Smaller
                                    companies  may have limited  product  lines,
                                    markets or financial  resources.  Securities
                                    of  smaller  companies  may trade at a lower
                                    volume than more widely held  securities and
                                    may  fluctuate  in value more  sharply  than
                                    those of other securities. The Fund is not a
                                    "diversified" fund within the meaning of the
                                    Investment Company Act of 1940. Accordingly,
                                    the  Fund  may   invest   its  assets  in  a
                                    relatively  small  number of  issuers,  thus
                                    making an investment in the Fund potentially
                                    more   risky   than  an   investment   in  a
                                    diversified fund which is otherwise  similar
                                    to the  Fund.  Loss  of  money  is a risk of
                                    investing in the Fund.

Who Should Invest in the Fund:      The  Fund  is  not  intended  to  provide  a
                                    balanced  investment  program.  The  Fund is
                                    most suitable for an investor who is willing
                                    to  accept a higher  degree  of risk than in
                                    some other mutual funds.

INVESTMENT OBJECTIVE, PRINCIPAL STRATEGIES, POLICIES AND RISKS

The Fund seeks to create long-term capital appreciation for its shareholders by investing primarily in equities of public companies with strong, above-average prospective long-term growth rates. Typically, these above average growth rates are exhibited by companies addressing the challenges of rapid and fundamental changes in the world economy resulting from demographic, political and technological change. In this manner, the Fund seeks to build wealth for long-term investors. The Fund strives to balance tax efficiency with the inherent volatility in rapid growth markets and industries. The central premise of the Fund's investment style is growth, but more specifically to move early into emerging areas of rapid growth, to stay with the leaders in established growth markets and to aggressively exit or short areas and/or companies that the Fund believes can no longer sustain strong, above average growth profitably. The principal investment strategies of the Fund are detailed below:

The Fund generally seeks to invest in companies which exhibit the following characteristics:

o STRONG GROWTH POTENTIAL. The Fund seeks markets and industries with strong growth potential. Finding the areas with the greatest unmet needs leads one to the companies attempting to satisfy those needs, most often delivering strong growth opportunities. The Fund concentrates on market and industry niche opportunities with large, multiyear growth prospects.

o MARKET LEADERS. The Fund will focus on the leaders in these growth markets which often garner a disproportionate share of the positive financial returns. The Fund seeks to identify these leaders as they are emerging and before they are widely recognized. At times, this may require investing in private companies in various stages of development subject to the investment restrictions set forth in this Prospectus and in the Statement of Additional Information. In selecting private companies for initial or continued inclusion in the Fund, the Fund shall employ the same investment strategies and standards used when selecting a publicly-held company.

o HIGH OPERATING MARGINS. The Fund will concentrate on industries or companies with the potential to deliver strong profits, not just high revenue growth. The Fund focuses on companies with the potential for high profit margins and strong cash generation. Often, high margins are a sign that a company's products and services have a high-perceived value to its customers. High operating margins are also often indicative of companies with strong execution capabilities. It also provides companies with the financial flexibility to invest for growth.

o LONG-TERM, SUSTAINABLE GROWTH. The Fund will focus on the sustainability of strong growth, not just the absolute rate of change. The Fund considers the best growth stocks to be those that can sustain strong growth over long periods of time. Many companies can grow rapidly over short periods of time, far fewer have the resources, positioning and execution abilities to deliver superior growth records over time.

o COMPANIES ADDRESSING UNMET NEEDS. The Fund will invest in a company in any industry or geographic market where it believes that a company's new or differentiated product or service is addressing a substantially unmet need. Most high

-3-

growth companies are in high growth markets, but others arise in mature sectors of the economy where new products and services, particularly those technologically driven, present new growth opportunities. The Fund seeks to diversify among industries to moderate risk but will not do so at the expense of limiting growth opportunities. In the intermediate term, it is expected that a majority of the Fund's investments will be in healthcare, technology, business and consumer services, media, communications, financial and energy companies where the greatest growth opportunities presently reside.

o STRONG MANAGEMENT STRATEGY AND PERFORMANCE. Quality of management and balance sheets will play key roles in the Fund's investment decision process. A key part of sustainability is having the managerial and financial resources to fund strong growth. Balance sheets trends are also an important indicator to the health of the business. Beyond a management's historical performance record, the Fund focuses on the overall strategic vision and tactical decisions in assessing a company's growth potential.

The Fund utilizes the following investment strategies and techniques:

o FUNDAMENTAL COMPANY AND MARKET ANALYSIS. The Fund relies foremost on fundamental company and market analysis and secondarily on macro-economic analysis to arrive at its investment decisions. The Fund puts a premium on in-depth company and industry analysis. The Fund managers intend to visit frequently with company managements, attend trade shows and other industry conferences and develop other sources of independent insight. The Fund tracks key economic and political events as they affect the relative attractiveness and growth prospects of the portfolio companies. However, given the uneven history of economic forecasting and the fact that many of the best growth companies can continue to grow even in a challenging economic environment, the Fund will rely foremost on finding the best- positioned companies and not on market-timing.

o DISCIPLINED APPROACH TO VALUATION. The Fund seeks to enhance shareholder returns with a disciplined approach to valuations, both relative and absolute. Since the markets' valuations fluctuate due to many factors, including economic and political uncertainties, inflation perceptions and competition from other asset classes, the Fund looks to value stocks both relative to the market and relative to other growth companies seeking to pay the least for the most amount of sustainable growth. While growth stocks have generally carried high relative valuations to the market, even the best of growth companies can become overvalued. The Fund believes that there are relatively few superior growth companies and, therefore, will tolerate some short- term overvaluation. However, the Fund intends to sell any holding if the absolute level of valuation, in its opinion, outstrips the growth potential of that company.

o SHORT SELLING. The Fund intends to actively short highly valued companies in these high growth sectors with challenged cost structures and balance sheets, eroding competitive positions and rapidly decelerating end demand. High growth markets invite numerous competitors, many of which do not survive. In the early stages of new markets it is not always clear who the real winners will be. As the better

-4-

companies emerge, the Fund looks to short the weaker competitors when the Fund believes their valuations do not yet reflect their weaker status.

o HEDGING. The Fund seeks to employ hedging techniques where appropriate to reduce some of the high volatility inherent to rapidly changing markets and industries. Growth markets and industries are more volatile than established industries and hence, the related stocks are also more volatile. The Fund will use options and other hedging strategies to control high volatility to facilitate more consistent returns.

In summary, the keys to successful investing by the Fund include an understanding of macro economic and political trends, an evaluation of the high growth sectors of the economy, indentifying a sector's leaders and laggards, frequent visits with company management and an analysis of companies' business fundamentals, quality of management and competitive position. After finding an attractive growth candidate for the Fund, the specific company's valuation is evaluated relative to its prospects and competing candidates, both current holdings and other potential investments, to determine if enough appreciation potential is available to warrant inclusion in the Fund.

Also, the Fund will engage in a constant analysis of the existing Fund investments to ensure that their growth, profitability and valuation warrant their remaining in the Fund. Positions will be sold when they no longer meet the long-term investment objectives of the Fund.

The Fund has adopted certain investment restrictions which are fundamental and may not be changed without a shareholder vote. Except as specifically noted, the Fund's investment objectives and policies described in the following pages are not fundamental policies and may be changed or modified by the Board of Directors of The Needham Funds, Inc. without shareholder approval. The Fund will not, however, change its investment objective without first providing written notice to its shareholders at least 30 days in advance. A complete list of the Fund's investment restrictions, both fundamental and non-fundamental, and certain other policies not described in the Prospectus may be found in the Statement of Additional Information.

Under normal market conditions, the Fund intends to invest at least 65% of its total assets in equity securities of domestic issuers listed on a nationally recognized securities exchange or traded on the Nasdaq System. The balance of the Fund's assets may be held in cash or invested in other securities, including preferred stock, common stock equivalents (mainly securities exchangeable for common stock), options, futures and various corporate debt instruments.

EQUITY SECURITIES

The Fund emphasizes investments in common stocks which may include equity securities of smaller companies. The Fund also may buy securities such as convertible debt, preferred stock, warrants, or other securities exchangeable for shares of common stock and other equity securities, including publicly traded partnership interests. In selecting equity investments for the Fund, the Adviser seeks to identify companies in a variety of industries, including but not limited to the technology, healthcare, business and consumer services, media, communications, financial and energy industries, which it believes will achieve superior growth rates, based on its market research and company analysis. When investing in technology the Adviser focuses on product cycles and unit growth. When investing in healthcare the Adviser focuses heavily on demographic, regulatory and lifestyle trends. The Adviser will consider overall growth prospects, financial condition, competitive

-5-

position, technology, research and development, productivity, labor costs, raw materials costs and sources, competitive operating margins, return on investment, management and other factors.

BORROWING AND LEVERAGE

As a fundamental policy, the Fund may borrow from banks up to 25% of its total assets and may pledge its assets in connection with these borrowings. If the Fund makes additional investments while borrowings are outstanding, this may constitute a form of leverage. This leverage may exaggerate changes in the Fund's share value and the gains and losses on the Fund's investments.

SHORT SALES

The Fund may sell securities short and borrow the same security from a broker or other institution to complete the sale. The Fund may make a profit or loss depending upon whether the market price of the security decreases or increases between the date of the short sale and the date on which the Fund replaces the borrowed security. All short sales must be fully collateralized and the Fund will not sell short securities the underlying value of which exceeds 25% of the value of the net assets of the Fund. The Fund will also limit short sales in any one issuer's securities to 2% of the Fund's net assets and will not sell short more than 2% of any one class of the issuer's securities.

OPTIONS, FUTURES AND FORWARD CONTRACTS

The Fund may buy and sell options and futures contracts to manage its exposure to changing interest rates, security prices, currency exchange rates and precious metals prices. The Fund may enter into forward contracts as a hedge against future fluctuations in foreign exchange rates. The Fund may buy and sell stock index futures contracts or related options in anticipation of general market or market sector movements. The Fund may also invest in indexed securities or related options, the value of which is linked to currencies, interest rates, commodities, indices, or other financial indicators. Options and futures may be combined with each other or with forward contracts in order to adjust the risk and return characteristics of the overall strategy. The Fund may invest in options and futures based on any type of security, index, or currency related to their investments, including options and futures traded on foreign exchanges and options not traded on exchanges.

Except as described below, the Fund will not engage in options, futures or forward transactions, other than for hedging purposes, if, as a result, more than 5% of its total assets would be so invested. The Fund may engage in these kinds of transactions to an unlimited extent for hedging purposes.

Options, futures and forward contracts can be volatile investments and involve certain risks. The ability of the Fund to use these strategies successfully will depend on the Adviser's ability to predict pertinent market movements, which cannot be assured. If the Fund makes a transaction at an inappropriate time or judges market conditions incorrectly, options and futures strategies may significantly lower the Fund's return. The Fund will comply with applicable regulatory requirements when implementing these strategies, techniques and instruments. See Statement of Additional Information.

DEFENSIVE INVESTMENTS

The Fund may invest temporarily up to 100% of its assets in cash or cash equivalents, investment grade debt securities or repurchase agreements for defensive purposes. Consistent with the Fund's investment objectives and policies, the Adviser may make changes in the portfolio

-6-

whenever it believes that doing so is in the best interest of the Fund. To the extent the Fund takes defensive positions, it may not achieve its investment objectives.

NON-DIVERSIFICATION AND INVESTMENT IN MARKET SECTORS

The Fund is "non-diversified" for purposes of the Investment Company Act of 1940 and so has the flexibility to invest its assets in the securities of fewer issuers than if it was "diversified." To the extent the Fund invests a significant portion of its assets in a few issuers' securities, the performance of the Fund could be significantly affected by the performance of those issuers. The Fund must, however, meet certain diversification requirements under Federal tax law. See Statement of Additional Information--"Investment Restrictions."

As a fundamental policy, the Fund will not invest more than 25% of its net assets in issuers conducting their principal business in the same industry. However, the Fund at times may invest more than 25% of its total assets in securities of issuers in one or more market sectors. A market sector may be made up of companies in a number of related industries. Business and economic developments affecting that sector likely would have greater effect on the Fund than those same developments would have on a fund invested in a wider spectrum of market or industrial sectors.

RISK FACTORS

The Fund invests primarily in equity securities, which fluctuate in value. Therefore, shares of the Fund will also fluctuate in value. Political and economic news can influence marketwide trends. Other factors may be ignored by the market as a whole but may cause price swings in a single company's stock or the stocks of the companies within a given industry. The net asset value of the Fund's shares, to the extent the Fund invests in debt securities, is affected by changes in the general level of interest rates.

Investments in smaller companies may offer greater opportunities for capital appreciation than larger companies, but may also involve certain special risks. These companies may have limited product lines, markets, or financial resources and may be dependent on a limited management group. These securities may also trade less frequently and at a lower volume than more widely held securities, and may fluctuate in value more sharply than those of other securities. There may be less available information about these issuers or less market interest than is normally the case with respect to larger companies.

Subject to the Fund's investment policies and restrictions on investments in illiquid securities, the Fund may invest in privately-held companies. Investments in companies in the early stages of development, particularly those companies which have yet to offer securities to the public, may offer greater opportunities for capital appreciation than longer-established or publicly-held companies. However, investments in these companies are often riskier than investments in longer-established or publicly-held companies. Typically, there is very little public information available on these companies, their management philosophies and strategies may be untested, their product lines, markets and financial resources may be limited and the restrictions on re-sale of securities of such companies imposed by U.S. securities laws and by market forces in general may make it difficult for the Fund to liquidate any position it may have in such a company. Even if the Fund is able to liquidate its position in such a company, it may be forced to do so at prices which are not beneficial to the Fund. See Statement of Additional Information -- "Description of the Fund and Investment Objective and Policies."

Certain investment techniques described in this Prospectus, such as short sales, options and futures strategies and leverage, may entail risks and may result in significant capital loss. The Fund

-7-

may engage in various strategies as described above, to varying degrees, both to seek to increase its return and to hedge its portfolio against movements in the securities markets and exchange rates. Use of these strategies involves the risk of imperfect correlation in movements in the price of options and futures and movements in the price of the securities or currencies which are the subject of the hedge. There can be no assurance that a liquid secondary market for options and futures contracts will exist at any specific time. Options and futures contracts, and certain of the other investments described above and in the Statement of Additional Information, may be considered "derivative" investments, and entail certain risks described above and in the Statement of Additional Information.

The Fund anticipates that in the year 2001 its annual portfolio turnover rate will be relatively insubstantial as the Fund will have been in operation for only a portion of the year. However, for the year 2002, the Fund anticipates that its annual portfolio turnover rate may be between 100% - 200%. This rate of turnover will likely result in higher brokerage commissions and higher levels of realized gains than if the turnover rate was lower and may subject investors to higher levels of taxable gains.

In addition, the Fund may invest in the securities of non-U.S. issuers, which have risks that are different from the risks associated with investments in the securities of U.S. issuers. See Statement of Additional Information--"Description of the Fund and Investment Objective and Policies."

DISTRIBUTION ARRANGEMENTS

Needham & Company, Inc., an affiliate of the Adviser, acts as a distributor for the Fund. Rule 12b-1 adopted by the Securities and Exchange Commission under the Investment Company Act of 1940 permits an investment company to directly or indirectly finance any activity associated with the distribution of its shares and/or shareholder-related services in accordance with a plan adopted by the Board of Directors. Pursuant to this rule, the Directors of The Needham Funds, Inc. have approved, and The Needham Funds, Inc. has entered into, a Distribution and Services Agreement (the "Distribution Agreement") with Needham & Company, Inc. under which the Fund may pay a service fee to Needham & Company, Inc. or others at an annual rate of up to 0.25 of 1% of the aggregate average daily net assets of the Fund which are attributable to Needham & Company, Inc. or the various other service providers. These fees are paid out of the Fund's assets on an on-going basis, and thus over time these fees may increase the cost of your investment and may cost you more than paying other types of sales charges. In addition, the Adviser may pay amounts from its own resources for the provision of such services.

-9-

The Distribution Agreement provides that Needham & Company, Inc. will use the services fee received from the Fund, in part, for payments (i) to compensate broker-dealers or other persons for providing distribution assistance, (ii) to otherwise promote the sale of shares of the Fund such as by paying for the preparation, printing and distribution of prospectuses for other than current shareholders and sales literature or other promotional activities, and (iii) to compensate banks and other qualified financial institutions for providing administrative, accounting and shareholder liaison services with respect to the Fund's shareholders. Some payments under the Distribution Agreement are used to compensate broker-dealers based on assets maintained in the Fund by their customers. Distribution services fees are accrued daily, paid monthly and charged as expenses of the Fund as accrued. Distribution services fees received from the Fund will not be used to pay any interest expenses, carrying charges or other financial costs. In adopting the Distribution Agreement, the Directors of The Needham Funds, Inc. determined that there was a reasonable likelihood that the Distribution Agreement would benefit the Fund and the shareholders.

The Needham Funds, Inc. and/or Needham & Company, Inc. may enter into related servicing agreements appointing various firms, such as broker-dealers or banks, to provide all or any portion of the foregoing services for their customers or clients through the Fund. The Fund and/or Needham & Company, Inc. may enter into servicing agreements with banks and others, including the Adviser or its affiliates, to provide these kinds of services.

The administrative and accounting services provided by banks and other qualified financial institutions may include, but are not limited to, establishing and maintaining shareholder accounts, sub-accounting, processing of purchase and redemption orders, sending confirmation of transactions, forwarding financial reports and other communications to shareholders and responding to shareholder inquiries regarding the Fund.

HOW TO PURCHASE SHARES

You may purchase shares of the Fund at net asset value without any sales or other charge by sending a completed application form and check to:

Needham Aggressive Growth Fund c/o PFPC Inc.
P.O. Box 8949
Wilmington, DE 19899-8949

However, you should not send any correspondence by overnight courier to this post office box address. Correspondence sent by overnight courier should be addressed to the Fund at:

Needham Aggressive Growth Fund c/o PFPC Inc.
400 Bellevue Parkway, Suite 108 Wilmington, DE 19809

Telephone transactions may not be used for initial purchases. If you want to make subsequent telephone transactions, select this feature on your Application or call 1-800-625-7071 to request an authorization form to set up your account for this feature. PFPC Inc. is the Administrator of the Fund.

-10-

You also may purchase shares of the Fund through authorized broker-dealers or other institutions who may charge for their services. These sales agents have the responsibility of transmitting purchase orders and funds, and of crediting their customers' accounts following redemptions in a timely manner and in accordance with their customer agreements and this Prospectus.

The minimum initial investment for individuals, corporations, partnerships or trusts is $5,000. There is a $500 minimum for subsequent investments. Shares of the Fund are offered on a continuous basis. The Fund, however, reserves the right, in its sole discretion, to reject any application to purchase shares. Your application will not be accepted unless it is accompanied by a check drawn on a U.S. bank, savings and loan, or credit union in U.S. funds for the full amount of the shares to be purchased. No third party checks will be accepted.

For IRAs, the minimum initial investment is $1,500 and there is no minimum for subsequent investments.

After you open an account, you may purchase additional shares by sending a check payable to Needham Aggressive Growth Fund and using the address given above. Please include your Needham account number on the check. All shares will be purchased at the net asset value per share next determined after receipt of your application in proper order and acceptance of your application by the Fund. Subsequent investments may also be made by telephone (electronic funds transfer) from a bank checking or money market account. The transfer must specify the account name, your address and your Needham account number. You must set up this feature in advance according to the above instructions.

The Fund will charge a $25.00 fee against your account, in addition to any loss sustained by the Fund, for any payment check returned for insufficient funds.

You should contact the Fund at 1-800-625-7071 to obtain the latest wire instructions for wiring funds to PFPC Inc. for the purchase of Fund shares and to notify PFPC Inc. that a wire transfer is coming.

Additionally, the Fund charges a short-term trading fee of .75% at the time of redemption on shares held less than 30 days. This fee is paid to the Fund and is designed to protect and benefit long-term shareholders.

AUTOMATIC INVESTMENT PROGRAM

You may also be eligible to participate in the Fund's Automatic Investment Program, an investment plan that automatically debits money from your bank account and invests it in the Fund through the use of electronic funds transfers or automatic bank drafts. This feature must be set up by you in advance. You may elect to make subsequent investments by transfers of a minimum of $100 on the fifth or twentieth day of each month into your established Fund account. Contact shareholder services at 1-800-625-7071 for more information about the Fund's Automatic Investment Program.

NET ASSET VALUE

The price of the Fund's shares is based on the net asset value of the Fund. The net asset value per share of the Fund will be determined on each day when the New York Stock Exchange (the "Exchange") is open for business at the close of the Exchange and will be computed by determining

-11-

the aggregate market value of all assets of the Fund less its liabilities, and then dividing that amount by the total number of the Fund's shares outstanding. The determination of net asset value for a particular day is applicable to all applications for the purchase of shares as well as all requests for the redemption of shares received before the close of trading on the Exchange on that day. Therefore, the price at which a purchase or redemption is effected is based on the next calculation of net asset value after the order is placed.

Portfolio securities and options positions for which market quotations are readily available are stated at the last sale price reported by the principal exchange for each such security as of that exchange's close of business. Securities and options for which no sale has taken place during the day and securities which are not listed on an exchange are valued at the mean of the current closing bid and asked prices. All other securities and assets for which market quotations are not readily available are valued at their fair value as determined in good faith by the Board of Directors, although the actual calculations may be made by persons acting pursuant to the direction of the Board of Directors. The assets of the Fund may also be valued on the basis of valuations provided by a pricing service approved by or on behalf of the Board of Directors.

HOW TO REDEEM SHARES

You may redeem your shares at any time. You are entitled to redeem all or any portion of the shares credited to your accounts by submitting a written request for redemption by regular mail to:

Needham Aggressive Growth Fund c/o PFPC Inc.
P.O. Box 8949
Wilmington, DE 19899-8949

Redemption requests sent by overnight courier should be sent to:

Needham Aggressive Growth Fund c/o PFPC Inc.
400 Bellevue Parkway, Suite 108 Wilmington, DE 19809
1-800-625-7071

After the receipt of a redemption request, you will receive a check based on the net asset value next determined after the redemption request was received, which may be more or less than the amount originally invested. If the shares to be redeemed represent an investment made by check, the Fund reserves the right to withhold the proceeds until the check clears. It will normally take up to three days to clear local checks and up to seven days to clear other checks, but may take longer under some circumstances.

Your written redemption request will be considered to have been received in "proper order" if the following conditions are satisfied:

o your request is in writing, indicates the number of shares to be redeemed and identifies your account number;

o your request is signed by you exactly as the shares are registered;

-12-

o your request is accompanied by certificates, if any, issued representing the shares, which have been endorsed for transfer (or are themselves accompanied by an endorsed stock power) exactly as the shares are registered; and

o if you are requesting that the redemption proceeds be sent other than to the address of record or if the proceeds of a requested redemption exceed $50,000, the signature(s) on the request must be guaranteed by an eligible signature guarantor through a recognized medallion program. You can obtain a signature guarantee from a domestic bank or trust company, broker, dealer, clearing agency or savings association which is a participant in a medallion program recognized by the Securities Transfer Association. The three recognized medallion programs are Securities Transfer Agents Medallion Program (STAMP), Stock Exchanges Medallion Program (SEMP) and New York Stock Exchange, Inc. Medallion Signature Program (MSP). Signature guarantees which are not a part of these programs will not be accepted.

Your written redemption request will not be effective until all documents are received in "proper order" by PFPC Inc.

TELEPHONE REDEMPTIONS

The Fund permits individual shareholders or a representative of record for an account (once within a 30 day period) to redeem shares by telephone in amounts up to $10,000 by calling 1-800-625-7071. In order to use this service, you must have elected to do so in your Application or complete an authorization form supplied by the Fund. Telephone redemptions must be in amounts of $1,000 or more. Instructions must include your account number. Checks issued must be made payable to the owner of record and may only be mailed to the address of record. The request cannot be honored if an address change has been made for the account within 60 days of the telephone redemption request.

If there are multiple account owners, PFPC Inc. may rely on the instructions of only one owner. This account option is not available for retirement account shares or newly purchased (within the prior 15 days) shares. PFPC Inc. may record all calls.

The Fund will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. These procedures may include, among other things, requiring some form of personal identification prior to acting upon telephone instructions. The Fund reserves the right to refuse a telephone redemption if it believes it is advisable to do so. Assuming the Fund's security procedures are followed, neither the Fund nor PFPC Inc. will be responsible for the authenticity of redemption instructions received by telephone and believed to be genuine and any loss therefrom will be borne by the investor. During periods of substantial economic or market change, telephone redemptions may be difficult to complete. You may always redeem shares by mail if you are unable to contact the Fund by telephone.

ADDITIONAL INFORMATION ON REDEMPTIONS

As stated above, shares held less than 30 days are subject to a short-term trading fee of .75% at the time of redemption.

If you hold Fund shares in non-certificate form, you may elect to have redemption proceeds of $5,000 or more wired to your brokerage account or a commercial bank account designated by you. The current fee for this service is $7.50.

-13-

If you have an IRA or other retirement plan, you must indicate on your redemption request whether or not to withhold Federal income tax. Redemption requests failing to indicate an election not to have Federal income tax withheld will be subject to withholding.

You may also redeem Fund shares through broker-dealers holding such shares who have made arrangements with the Fund permitting redemptions by telephone or facsimile transmission. These broker-dealers may charge a fee for this service.

If your transactions in the Fund's shares at any time reduce your account value to below $1,000, the Fund may choose to notify you that, unless your account is brought up to at least such minimum amount, the Fund may, within a reasonable time, redeem all your shares in the account and close it by making payment to you of the proceeds.

SHAREHOLDER SERVICES

The Fund offers certain tax-sheltered retirement plans through which you may purchase shares, including IRAs (and "rollovers" from existing retirement plans) for you and your spouse, SEP-IRAs and Roth IRAs. Shares of the Fund may also be purchased by Qualified Retirement Plans such as profit-sharing and money purchase plans, 401(k) Plans and other Defined Contribution Plans, and by Defined Benefit Plans. These types of accounts may be established only upon receipt of a written application form. Should you have questions on the purchase of shares by retirement plans, please call 1-800-625-7071 and ask for Shareholder Services.

TAX STATUS, DIVIDENDS AND DISTRIBUTIONS

The Fund intends to make annual distributions to its shareholders of record of substantially all of its realized net capital gains (the excess of realized net long-term capital gains over realized net short-term capital losses), any realized net gains from foreign currency transactions, net investment income and the excess, if any, of realized net short-term capital gains over realized net long-term capital losses. The Fund may make additional distributions, if necessary, to avoid a 4% Federal excise tax on certain undistributed ordinary income and capital gain net income. Certain distributions made to shareholders of record as of a date in October, November or December of a given year which are paid by the Fund in January of the immediately subsequent year will be taxable to shareholders as if received on December 31 of such given year.

Dividends (whether paid in cash or reinvested in additional Fund shares) are taxable to shareholders as ordinary income. Distributions of net capital gain (the excess of net long-term capital gains over net short-term capital losses) are also taxable to shareholders. In general, a noncorporate shareholder's net capital gains will be taxed at a maximum rate of 20% for property held more than 12 months, and the maximum rate is reduced to 18% for property acquired after December 31, 2000 and held for more than five years. Distributions of net investment income and capital gain net income are taxable whether received in cash or reinvested in additional shares.

Unless a shareholder elects to do otherwise, all dividends and capital gains distributions from the Fund will be automatically reinvested in additional full and fractional Fund shares. Shareholders who do not wish to have dividends and distributions automatically reinvested in Fund shares may choose between two options:

(1) automatic reinvestment of capital gains distributions in Fund shares and payment of dividends in cash; or

-14-

(2) payment of all dividends and distributions in cash.

Shareholders may change this election at any time by notifying the Administrator or their account representative if the account is maintained at an eligible broker-dealer or bank. Dividends and distributions will be reinvested at the Fund's per share net asset value on the reinvestment date established for the dividend or distribution.

The Fund is required to withhold as "backup withholding" 31% of all dividends, capital gain distributions and redemption proceeds payable to any individuals and certain other non-corporate shareholders who do not provide the Fund with a correct taxpayer identification number and certain required certifications or who are otherwise subject to backup withholding. Upon a redemption of Fund shares, a shareholder will ordinarily recognize a taxable gain or loss, subject to certain Federal tax rules. The Fund anticipates that it will be subject to foreign withholding taxes which it may, in certain years, be able to pass through as a credit or deduction to its shareholders.

The foregoing is only a summary of some of the important Federal tax considerations generally affecting the Fund and shareholders. In addition to those considerations, there may be other Federal, state, local, or foreign tax considerations applicable to a particular investor. Prospective shareholders are therefore urged to consult their tax advisers with respect to the effects of the investment on their own tax situations.

ADMINISTRATOR, SHAREHOLDER
SERVICING AGENT AND TRANSFER AGENT

The Fund employs PFPC Inc. as Administrator under an administration contract dated January 2, 1996, as amended (the "Administration Contract") to provide administrative services to the Fund. The services provided by PFPC Inc. under the Administration Contract are subject to the supervision of the officers and Directors of The Needham Funds, Inc., and include day-to-day administration of matters related to the corporate existence of the Fund, maintenance of its records and preparation of reports. Subject to certain waivers for these services, the Fund pays a monthly fee at the annual rate of 0.10% on the first $200 million of average daily net assets of the Fund, subject to annual minimums.

PFPC Inc. also provides various shareholder services made available to each shareholder, including performance of transfer agency and registrar functions and dividend paying agent. PFPC Inc. acts as the Fund's shareholder servicing agent. The principal address of PFPC Inc. is 400 Bellevue Parkway, Wilmington, DE 19809.

CUSTODIAN

PFPC Trust Company acts as custodian for the Fund. Its address is 400 Bellevue Parkway, Wilmington, DE 19809. Rules adopted under the Investment Company Act of 1940 permit the Fund to maintain its non-U.S. securities and cash in the custody of certain eligible banks and securities depositories. Pursuant to these rules, the Fund's non-U.S. securities and cash are held by its sub-custodians who have been approved by or under the delegated authority of the Board of Directors of The Needham Funds, Inc. in accordance with the rules of the Securities & Exchange Commission. Selection of the sub-custodians and any decision to invest in non-U.S. markets has been made following a consideration of a number of factors, including, but not limited to, the practices, procedures, internal controls and financial stability of the institution, the ability of the institution to perform capable custodial services for the Fund and provide reasonable care for Fund assets, the reputation and standing of the institution in its national market, the political and economic stability of the countries in which the sub-custodians will be located, and risks of potential

-15-

nationalization or expropriation of Fund assets. In addition, the Investment Company Act of 1940 requires that non-U.S. sub-custodians, among other requirements, have no lien on the assets of the Fund and maintain adequate accessible records.

i

DESCRIPTION OF THE FUND AND INVESTMENT OBJECTIVE AND POLICIES

The Needham Funds, Inc. is an open-end management investment company organized as a corporation under the laws of the State of Maryland on October 12, 1995. This Statement of Additional Information relates to Needham Aggressive Growth Fund (the "Fund") which is a series of The Needham Funds, Inc.

The Fund is a non-diversified, open-end management investment company under the Investment Company Act of 1940 (the "Act") and is offered on a no-load basis.

The Fund seeks long-term capital appreciation by primarily investing in equities of public companies with strong, above-average prospective long-term growth rates. The Fund seeks to achieve its objectives by, under normal market conditions, investing at least 65% of its total assets in equity securities of domestic issuers listed on a nationally recognized securities exchange or traded on the Nasdaq System. The balance of the Fund's assets may be held in cash or invested in other securities, including preferred stock, common stock equivalents, options, futures and various corporate debt instruments.

DEBT SECURITIES

The Fund may buy debt securities of all types issued by both domestic and foreign issuers, including government securities, corporate bonds and debentures, commercial paper, and certificates of deposit. It is the Fund's intention to invest no more than 35% of its total assets in debt securities.

LOWER-RATED DEBT SECURITIES

The Fund may purchase lower-rated debt securities, sometimes referred to as "junk" or "high yield bonds" (those rated BB or lower by Standard & Poor's Corporation ("S&P") or Ba or lower by Moody's Investors Service, Inc. ("Moody's")). However, no more than 10% of the Fund's total assets (such 10% also being included in the 35% limitation stated above) may be invested in non- investment grade debt securities. These securities are considered to be highly speculative, may have poor prospects of attaining investment standing and may be in default. Like those of other fixed-income securities, the value of lower-rated securities fluctuate in response to changes in interest rates. In addition, the values of such securities are also affected by changes in general economic conditions and business conditions affecting the specific industries of their issuers.

The lower ratings of certain securities held by the Fund reflect the greater possibility that adverse changes in the financial condition of the issuer, or in general economic conditions, or both may impair the ability of the issuer to make payments of interest and principal. A number of factors,

1

including ability of the issuer to make timely payments, could lessen liquidity and limit the Fund's ability to sell at prices approximating the values the Fund placed on such securities. In the absence of a liquid trading market for securities held by the Fund, it may be difficult to establish the fair market value of these securities. The rating assigned to a security by Moody's or S&P does not reflect an assessment of the volatility of the security's market value or of the liquidity of an investment in the security.

Changes by recognized rating services in their ratings of any fixed-income security and in the ability of an issuer to make payments of interest and principal may also affect the value of these investments.

Issuers of lower-rated securities are often highly leveraged and, consequently, their ability to service their debt during an economic downturn or during sustained periods of rising interest rates may be impaired. In addition, such issuers may be unable to repay debt at maturity by refinancing. The risk of loss due to default is significantly greater because such securities frequently are unsecured and subordinated to senior indebtedness. Certain of the lower-rated securities in which the Fund invests are issued to raise funds in connection with the acquisition of a company. The highly leveraged capital structure of such issuers may make them especially vulnerable to adverse changes in economic conditions.

In order to enforce its rights in the event of a default under such securities, the Fund may be required to take possession of and manage assets securing the issuer's obligations on such securities, which may increase the Fund's operating expenses and adversely affect the Fund's net asset value. The Fund may also be limited in its ability to enforce its rights and may incur greater costs in enforcing its rights in the event an issuer becomes the subject of bankruptcy proceedings.

OTHER DEBT SECURITIES

Zero-coupon securities are debt securities which are usually issued at a deep discount and do not provide for payment of interest prior to maturity. Even though zero-coupon securities do not pay current interest in cash, the Fund is nonetheless required to accrue interest income on them and to distribute the amount of that interest at least annually to shareholders. Thus, the Fund could be required at times to liquidate other investments in order to satisfy its distribution requirement.

When other debt obligations are stripped of their unmatured interest coupons by the holder, the stripped coupons are sometimes sold separately. The principal or corpus is then sold at a deep discount because the buyer receives only the right to receive a future fixed payment on the security and does not receive any rights to periodic cash interest payments. Purchasers of stripped principal obligations acquire, in effect, discount obligations that are economically identical to zero-coupon bonds.

2

INVESTING IN CONVERTIBLE SECURITIES

The Fund may invest in convertible securities: that is, bonds, notes, debentures, preferred stocks and other securities which are convertible into common stocks. Investments in convertible securities may provide incidental income through interest and dividend payments and/or an opportunity for capital appreciation by virtue of their conversion or exchange features.

Convertible debt securities and convertible preferred stocks, until converted, have general characteristics similar to both debt and equity securities. Although to a lesser extent than with debt securities generally, the market value of convertible securities tends to decline as interest rates increase and, conversely, tends to increase as interest rates decline. In addition, because of the conversion or exchange feature, the market value of convertible securities typically changes as the market value of the underlying common stocks changes and, therefore, also tends to follow movements in the general market for equity securities. As the market price of the underlying common stock declines, convertible securities tend to trade increasingly on a yield basis and so may not experience market value declines to the same extent as the underlying common stock. When the market price of the underlying stock increases, the prices of the convertible securities tend to rise as a reflection of the value of the underlying common stock, although typically not as much as the underlying common stock. While no securities investments are without risk, investments in convertible securities generally entail less risk than investments in common stock of the same issuer.

As debt securities, convertible securities are investments which provide for a stream of income (or in the case of zero-coupon securities, accretion of income) with generally higher yields than common stocks. Convertible securities generally offer lower yields than non-convertible securities of similar quality because of their conversion or exchange features.

Convertible securities are generally subordinated to other similar but non-convertible securities of the same issuer, although convertible bonds, as corporate debt obligations, enjoy seniority in right of payment to all equity securities, and convertible preferred stock is senior to common stock, of the same issuer. However, because of the subordination feature, convertible bonds and convertible preferred stock typically have lower ratings than similar non-convertible securities.

INVESTING IN FOREIGN SECURITIES

Certain of the Fund's investments may be of securities in issuers located in countries having repatriation restrictions. Investment in securities subject to repatriation restrictions of more than seven days will be considered illiquid securities and will be subject to the Fund's overall 15% limitation on investment in illiquid securities.

Individual foreign economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross national product, rate of inflation, capital reinvestment, resources, self-sufficiency and balance of payments position. Further, by investing in foreign securities the

3

Fund may encounter greater difficulties or be unable to pursue legal remedies or obtain judgments in foreign courts.

Because foreign securities typically will be denominated in foreign currencies, the value of such securities to the Fund will be affected by changes in currency exchange rates and in exchange control regulations and costs will be incurred in connection with conversions between currencies. A change in the value of a foreign currency against the U.S. dollar will result in a corresponding change in the U.S. dollar value of the Fund's securities denominated in that currency. Such changes will also affect the Fund's income and distributions to shareholders. The Fund may be affected either favorably or unfavorably by fluctuations in the relative rates of exchange between the currencies of different nations and the Fund therefore may engage in certain foreign currency hedging strategies. Such hedging strategies may include the purchase and sale of foreign currencies on a spot or forward basis or the purchase and sale of options or futures contracts with respect to foreign currencies. Such strategies involve certain investment risks and transaction costs to which the Fund might not otherwise be subject. These risks include dependence on the Adviser's ability to predict movements in exchange rates, as well as the difficulty of predicting, and the imperfect movements between, exchange rates and currency hedges.

Investments may be made from time to time in companies in developing countries as well as in developed countries. Although there is no universally accepted definition, a developing country is generally considered by the Adviser to be a country which is in the initial state of industrialization. Shareholders should be aware that investing in the equity and fixed income markets of developing countries involves exposure to unstable governments, economies based on only a few industries and securities markets which trade a small number of securities. Securities markets of developing countries tend to be more volatile than the markets of developed countries; however, such markets have in the past provided the opportunity for higher rates of return to investors. There are substantial risks involved in investing in securities issued by developing country companies which are in addition to the usual risks inherent in foreign investments. Some countries in which the Fund may invest may have fixed or managed currencies. Further, certain currencies may not be traded internationally. Certain of these currencies have experienced a steady devaluation relative to the U.S. dollar. Any devaluations in the currencies in which the Fund's portfolio securities are denominated may have a detrimental impact on the Fund.

With respect to certain foreign countries, there is the possibility of expropriation of assets, confiscatory taxation, political or social instability or diplomatic developments which could affect investment in those countries. There may be less publicly available information about a foreign financial instrument than about a U.S. instrument and foreign entities may not be subject to accounting, auditing, and financial reporting standards and requirements comparable to those of the U.S. There is generally less government supervision and regulation for exchanges, financial institutions and issuers in foreign countries than there is in the U.S. Moreover, certain foreign investments may be subject to foreign withholding taxes. Foreign markets have different clearance and settlement procedures and in certain markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct such

4

transactions. Delays in settlement could result in temporary periods when assets of the Fund are uninvested and no return is earned thereon. The inability of the Fund to make intended securities purchases due to settlement problems could cause the Fund to miss attractive investment opportunities. Inability to dispose of Fund securities due to settlement problems could also result either in losses to the Fund due to subsequent declines in value of the Fund security or, if the Fund has entered into a contract to sell the security, could result in possible liability to the purchaser.

Foreign securities such as those purchased by the Fund may be subject to foreign government taxes, higher custodian fees and dividend collection fees which could reduce the yield on such securities. Trading in futures contracts traded on foreign commodity exchanges may be subject to the same or similar risks as trading in foreign securities.

FOREIGN CURRENCY TRANSACTIONS

Under normal circumstances, consideration of the prospects for currency exchange rates will be incorporated into the long-term investment decisions made for the Fund with regard to overall diversification strategies. Although the Fund values its assets daily in terms of U.S. dollars, it does not intend physically to convert its holdings of foreign currencies into U.S. dollars on a daily basis. The Fund may do so from time to time and investors should be aware of the costs of currency conversion. Although foreign exchange dealers do not charge a fee for conversion, they do realize a profit based on the difference (the "spread") between the prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency to the Fund at one rate while offering a lesser rate of exchange should the Fund desire to resell that currency to the dealer. The Fund may use forward contracts, along with futures contracts and put and call options, to "lock in" the U.S. dollar price of a security bought or sold and as part of its overall hedging strategy. The Fund will conduct its foreign currency exchange transactions, either on a spot (i.e., cash) basis at the spot rate prevailing in the foreign currency exchange market or through purchasing put and call options on, or by entering into, futures contracts or forward contracts to purchase or sell foreign currencies. See "-- Forward Foreign Currency Exchange Contracts" and "-- Futures and Options Transactions."

It is impossible to forecast the market value of a particular portfolio security at the expiration of the contract. Accordingly, it may be necessary for the Fund to purchase additional foreign currency on the spot market (and bear the expense of such purchase) if the market value of the security is less than the amount of foreign currency that the Fund is obligated to deliver and if a decision is made to sell the security and make delivery of the foreign currency.

If the Fund retains the portfolio security and engages in an offsetting transaction, the Fund will incur a gain or a loss to the extent that there has been movement in forward currency contract prices. Additionally, although such contracts tend to minimize the risk of loss due to a decline in the value of the hedged currency, at the same time they tend to limit any potential gain which might result should the value of such currency increase.

5

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS

The Fund may enter into forward contracts as a hedge against future fluctuations in foreign exchange rates. A forward foreign currency exchange contract ("forward contract") involves an obligation to purchase or sell a fixed amount of U.S. dollars or foreign currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at the price set at the time of the contract. Unlike foreign currency futures contracts, which are standardized exchange-traded contracts, forward currency contracts are usually traded in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers.

The Fund may enter into forward contracts under various circumstances. For example, the Fund may enter into a forward contract for the purchase or sale of a security denominated in a foreign currency in order to "lock-in" the price of the security in U.S. dollars or some other foreign currency which the Fund is holding. By entering into a forward contract for the purchase or sale of a fixed amount of U.S. dollars or other currency for the amount of foreign currency involved in the underlying security transactions, the Fund will be able to protect itself against any adverse movements in exchange rates between the time the security is purchased or sold and the date on which payment is made or received. The Fund may also purchase a forward contract to hedge against an anticipated rise in a currency versus the U.S. dollar or other currency, pending investment in a security denominated in that currency.

The Fund may enter into a forward contract to sell or purchase, for a fixed amount of U.S. dollars or other currency, an amount of foreign currency other than the currency in which the securities to be hedged or purchased are denominated approximating the value of some or all of the portfolio securities to be hedged or purchased. This method of hedging, called cross-hedging, will be used when it is determined that the foreign currency in which the portfolio securities are denominated has insufficient liquidity or is trading at a discount as compared with some other foreign currency with which it tends to move in tandem. The Fund is permitted to enter into forward contracts with respect to currencies in which certain of its portfolio securities are denominated and on which options have been written.

In certain of the above circumstances the Fund may have realized fewer gains than had the Fund not entered into the forward contracts. Moreover, the precise matching of the forward contract amounts and the value of the securities involved will not generally be possible since the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the date the forward contract is entered into and the date it matures.

The Fund's Custodian will place cash or liquid equity or debt securities into a segregated account of the Fund in an amount equal to the value of the Fund's total assets committed to the consummation of forward foreign currency contracts. If the value of the securities placed in the segregated account declines, additional cash or securities will be placed in the account on a daily basis so that the value of the account will equal the amount of the Fund's commitments with respect

6

to such contracts. At maturity of a forward currency contract, the Fund may either sell the portfolio security and make delivery of the foreign currency or it may retain the security and terminate its contractual obligation to deliver the foreign currency prior to maturity by purchasing an "offsetting" contract with the same currency trade obligating it to purchase, on the same maturity date, the same amount of the foreign currency. There can be no assurance, however, that the Fund will be able to effect such a closing purchase transaction.

FUTURES AND OPTIONS TRANSACTIONS

The use of financial futures contracts and options on such futures contracts may reduce the Fund's exposure to fluctuations in the prices of portfolio securities and may prevent losses if the prices of such securities decline. Similarly, such investments may protect the Fund against fluctuation in the value of securities in which the Fund is about to invest.

The use of financial futures contracts and options on such futures contracts as hedging instruments involves several risks. First, there can be no assurance that the prices of the futures contracts or options and the hedged security will move as anticipated. If prices do not move as anticipated, the Fund may incur a loss on its investment. Second, investments in options, futures contracts and options on futures contracts may reduce the gains which would otherwise be realized from the sale of the underlying securities which are being hedged. Third, the effective use of options and futures contracts also depends on the Fund's ability to terminate options and futures positions as desired. There can be no assurance that there will be a sufficiently liquid market for the Fund to effect closing transactions at any particular time or at an acceptable price. If the Fund cannot close a futures position, or if limitations imposed by an exchange or board of trade on which futures contracts are traded prevent the Fund from closing out a contract, the Fund may incur a loss or may be forced to make or take delivery of the underlying securities or currencies at a disadvantageous time.

In addition, the purchase or sale of futures contracts or sale of options on futures contracts involve the risk that the Fund could lose more than the original margin deposit required to initiate the transaction. The purchase of options on futures contracts involves less potential risk than the purchase or sale of futures contracts because the maximum amount at risk is the premium paid for the options plus transaction costs. Although the maximum amount at risk when the Fund purchases an option on a security, currency, index or futures contract is the premium paid for the option plus transaction costs, there may be circumstances when the purchase of an option would result in a loss to the Fund, whereas the purchase of the underlying security, currency or futures contract would not, such as when there is no movement in the level of the underlying security, currency or futures contract. The value of an options or futures position relating to a non-U.S. currency may vary with changes in the value of either the currency involved or the U.S. dollar or both and has no relationship to the investment merits of individual non-U.S. securities held in a hedged investment portfolio.

The Fund may write covered call options on its underlying portfolio securities, whether equity or debt, on stock or bond indexes and on currencies in which the Fund invests. Covered call

7

writing may be used for hedging purposes and for closing long call positions and for achieving incremental income. A call option will be considered covered if the Fund (i) owns the security or currency underlying the written option, (ii) holds a call option on the underlying security, currency or index with a similar exercise price or (iii) maintains sufficient cash, cash equivalents or liquid high grade securities sufficient to cover the exercise price of the option.

The Fund may also write covered put options. This technique will be used when the Fund seeks to purchase a security, or group of securities in the case of an index option, at a price equal to or less than the prevailing market price at the time of the put sale. The Fund may also sell covered puts for achieving incremental income. A put will be considered covered if a Fund (i) maintains cash, cash equivalents or liquid, high grade debt obligations sufficient to cover the exercise price of the option, (ii) holds a put option on the underlying security with an exercise price equal to or greater than the exercise price of the written put or (iii) where the exercise price of the purchased put is lower than that of the written put, the Fund maintains sufficient cash, cash equivalents or liquid high grade debt obligations equal to the difference. Puts may also be written in order to close long put positions. In calculating the 5% limitation on options, futures and forward transactions, other than for hedging purposes, the Fund shall include the premiums paid on options and options on futures (excluding in-the-money amounts on such options) and the initial margin deposits on the Fund's futures positions.

In order to fix the cost of future purchases, the Fund may purchase calls on equity and debt securities that the Adviser intends to include in the Fund's portfolio. Calls may also be used to participate in an anticipated price increase of a security without taking on the full risk associated with actually purchasing the underlying security. The Fund may purchase puts to hedge against a decline in the market value of portfolio securities.

REPURCHASE AGREEMENTS AND REVERSE REPURCHASE AGREEMENTS

The Fund will only enter into a repurchase agreement where (i) the underlying securities are of the type which the Fund's investment policies would allow it to purchase directly, (ii) the market value of the underlying security, including accrued interest, will be at all times equal to or exceed the value of the repurchase agreement, and (iii) payment for the underlying securities is made only upon physical delivery or evidence of book-entry transfer to the account of the custodian or a bank acting as agent. The Fund will not enter into a repurchase agreement with a maturity of more than seven business days if, as a result, more than 15% of the value of the Fund's net assets would then be invested in such repurchase agreements and other illiquid securities.

The Fund may enter into reverse repurchase agreements in which the Fund sells securities and agrees to repurchase them at a mutually agreed date and price. Generally, the Fund will be able to keep the interest income associated with those portfolio securities while the securities reside with the other party to the agreement. Such transactions are advantageous if the interest cost to the Fund of the reverse repurchase transaction is less than the cost of otherwise obtaining the cash raised through the transaction.

8

Reverse repurchase agreements involve the risk that the market value of the securities that the Fund is obligated to repurchase under the agreement may decline below the repurchase price. In the event the other party under a reverse repurchase agreement becomes bankrupt or insolvent, the Fund's use of the proceeds of the agreement may be restricted pending a determination by the other party, or its trustee or receiver, whether to enforce the Fund's obligation to repurchase the securities.

SECURITIES LENDING

The Fund may lend its portfolio securities, provided (i) the loan is secured continuously by collateral consisting of U.S. Government securities, cash, or cash equivalents adjusted daily to have a market value at least equal to the current market value of the securities loaned, (ii) the Fund may at any time call the loan and regain the securities loaned, (iii) the Fund will receive any interest or dividends paid on the loaned securities, and (iv) the aggregate market value of securities loaned will not at any time exceed such percentage of the total assets of the Fund as the Directors may establish, but not to exceed 20%, including repurchase agreements. In addition, it is anticipated that the Fund may share with the borrower some of the income received on the collateral for the loan or that it will be paid a premium for the loan.

Before the Fund enters into a loan, the Adviser considers the relevant facts including the creditworthiness of the borrower. The risks in lending portfolio securities consist of possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially.

INDEXED SECURITIES

The Fund may purchase securities whose prices are indexed to the prices of other securities, securities indices, currencies, commodities, or other financial indicators. Indexed securities typically, but not always, are debt securities or deposits whose value at maturity or coupon rate is determined by reference to a specific instrument or statistic. The performance of indexed securities largely depends on the performance of the security, currency, commodity or other instrument to which they are indexed, as well as general economic factors in the U.S. or abroad. At the same time, indexed securities are subject to the credit risks associated with the issuer of the security and their values may decline substantially if the issuer's creditworthiness deteriorates. Indexed securities may be more volatile than the underlying instrument itself.

ADDITIONAL RISKS ASSOCIATED WITH HEDGING INSTRUMENTS

The Fund's ability to hedge effectively all or a portion of its securities depends upon the ability of the Adviser to predict correctly the degree to which price movements of securities held in the Fund's portfolio correlate to the price movements of the relevant hedging instruments. In addition, the effectiveness of any hedging strategy using index options, index futures, interest rate

9

options or interest rate futures depends upon the correlation between the components of the underlying index and the securities held by the Fund.

DEFENSIVE POSITIONS

The Fund may invest temporarily up to 100% of its assets in cash or cash equivalents, investment grade debt securities or repurchase agreements for defensive purposes. Consistent with the Fund's investment objectives and policies, the Adviser may make changes in the portfolio whenever it believes that doing so is in the best interest of the Fund. To the extent the Fund takes defensive positions, it may not achieve its investment objectives.

OTHER PERMITTED INVESTMENTS

The Fund may invest in securities issued by other investment companies within the limits prescribed by the 1940 Act and applicable rules thereunder. As a shareholder of another investment company, the Fund would bear, along with other shareholders, its pro rata portion of the other investment company's expenses, including advisory fees. These expenses thus would be in addition to the advisory and other expenses that the Fund bears in connection with its own operations.

The Fund may also purchase or sell portfolio securities on a when-issued or delayed delivery basis in compliance with applicable 1940 Act guidelines. When-issued or delayed delivery transactions involve a commitment by the Fund to purchase or sell securities with payment and delivery to take place in the future in order to secure what is considered to be an advantageous price or yield to the Fund at the time of entering into the transaction.

The Fund may also invest up to 15% of its net assets in illiquid securities, including restricted securities, (i.e., securities that are not readily marketable without registration under the Securities Act of 1933 (the "1933 Act")) and other securities that are not readily marketable. The Fund may purchase restricted securities that can be offered and sold to "qualified institutional buyers" under Rule 144A of the 1933 Act, and the Board of Directors of The Needham Funds, Inc. may determine, when appropriate, that specific Rule 144A securities are liquid and not subject to the 15% limitation on illiquid securities.
INVESTMENT RESTRICTIONS

The following investment restrictions have been adopted by the Fund as fundamental policies and may only be changed by the affirmative vote of a majority of the Fund's outstanding shares. The term "majority of the Fund's outstanding shares" means the vote of (i) 67% or more of the Fund's shares present at a meeting, if the holders of more than 50% of the outstanding shares of the Fund are present or represented by proxy, or (ii) more than 50% of the Fund's outstanding shares, whichever is less.

10

These investment restrictions provide that the Fund may not:

1. Make investments for the purpose of exercising control or management of the issuer;

2. Purchase or sell real estate or real estate mortgage loans (provided that such restriction shall not apply to securities secured by real estate or an interest therein or issued by companies which invest in real estate or interests therein), commodities or commodity contracts (except that the Fund may deal in forward foreign exchange between currencies and the Fund may purchase and sell interest rate and currency options, futures contracts and related options and indexed notes and commercial paper), or interests or leases in oil, gas or other mineral exploration or development programs (provided that such restriction shall not apply to securities issued by companies which invest in oil, gas or other mineral exploration or development programs);

3. Except as described in the Prospectus, purchase any securities on margin, except for use of short-term credit necessary for clearance of purchases and sales of portfolio securities (the deposit or payment by the Fund of initial or variation margin in connection with futures contracts or options transactions is not considered the purchase of a security on margin);

4. Borrow amounts and pledge assets in connection therewith in excess of 25% of its total assets taken at market value (including the amount borrowed), and then only from banks as a temporary measure, including to meet redemptions or to settle securities transactions and provided further that no additional investments shall be made while borrowings exceed 5% of total assets;

5. Issue senior securities, as defined in the 1940 Act, except that this restriction shall not be deemed to prohibit the Fund from making any otherwise permissible borrowings, mortgages or pledges, short sales, or entering into permissible reverse repurchase agreements, and options and futures transactions;

6. Underwrite any issuance of securities (except to the extent that the Fund may be deemed to be an underwriter within the meaning of the 1933 Act in the disposition of restricted securities);

7. Make loans of its securities exceeding 20% of its total assets; and

8. Invest 25% or more of its net assets in one or more issuers conducting their principal business in the same industry.

As matters of non-fundamental policy, the Fund may not:

1. Purchase securities of other investment companies, except in connection with a merger, consolidation, acquisition or reorganization, or if immediately thereafter not more than (i) 3% of the total outstanding voting stock of any one such company is owned by the Fund, (ii) 5% of the Fund's total assets, taken at market value, would be invested in any one such company, or (iii)

11

10% of the Fund's total assets, taken at market value, would be invested in such companies' securities. Any purchase by the Fund of securities of other investment companies, except in connection with a merger, consolidation, acquisition or reorganization, shall be made in the open market where no commission results other than customary brokerage commissions;

2. With respect to 50% of the value of its total assets, invest more than 25% of the value of its total assets in the securities of one issuer, and with respect to the other 50% of the value of its total assets, invest more than 5% of the value of its total assets in the securities of one issuer or acquire more than 10% of the outstanding voting securities of a single issuer. This restriction shall not apply to U.S. Government securities;

3. With respect to 75% of the value of its total assets, purchase more than 10% of the outstanding voting securities of any issuer;

4. The Fund may not sell short securities the underlying value of which exceeds 25% of the value of the net assets of the Fund. Any short sale up to such limit must be fully collateralized and the Fund will also limit its short sales in any one issuer's securities to 2% of the value of the Funds net assets and will not sell short more than 2% of any one class of the issuer's securities.

5. Invest in oil, gas or mineral exploration or development programs or leases;

6. Purchase or sell real estate or make real estate mortgage loans or invest in real estate limited partnerships not traded on a national securities exchange, except that the Fund may purchase or sell securities issued by entities engaged in the real estate industry or instruments backed by real estate;

7. Invest in warrants (other than warrants acquired by the Fund as a part of a unit or attached to securities at the time of purchase) if, as a result, such investment (valued at the lower of cost or market value) would exceed 5% of the value of the Fund's net assets, provided that any warrants in which the Fund is short "against the box" will be netted for purposes of this 5% limitation; and

8. Invest no more than 35% of its total assets in debt securities and invest no more than 10% of its total assets in non-investment grade debt securities (such 10% limitation to be included in the 35% limitation).

These restrictions are not fundamental policies and may be changed by the Board of Directors without a shareholder vote, to the extent permitted by applicable law including rules of the Securities Exchange Commission. Except as otherwise may be specifically stated herein, the Fund's other investment policies stated in this Statement of Additional Information and in the Prospectus are not considered fundamental and may be changed by the Board of Directors at any time without a shareholder vote if and to the extent any such changes are consistent with the requirements of the 1940 Act.

12

If a percentage restriction is adhered to at the time of the investment, a later increase or decrease in percentage resulting from a change in values of portfolio securities or amount of net assets will not be considered a violation of any of the foregoing restrictions. The Fund shall, however, reduce its holdings of illiquid securities in an orderly fashion in order to maintain adequate liquidity.

INVESTMENT ADVISER

The investment adviser of the Fund is Needham Investment Management L.L.C. (the "Adviser"), a Delaware limited liability company, pursuant to an Investment Advisory Agreement with The Needham Funds, Inc., dated as of January 1, 1996, as supplemented (the "Advisory Agreement"). The Adviser furnishes an investment program for the Fund and determines, subject to the overall supervision and review of the Board of Directors, what investments should be purchased, sold and held. The Adviser is ninety-nine percent (99%) owned by Needham & Company, Inc. Each of Messrs. Needham and Michaelson may be deemed to be control persons of Needham & Company, Inc. based upon their positions as officers, directors and/or the stockholders of that entity. See "Management" and "The Distributor and the Distribution of the Shares" in this Statement of Additional Information.

Under the terms of the Advisory Agreement, and at the direction of the Board of Directors, the Adviser maintains records and furnishes or causes to be furnished all required reports or other information concerning the Fund to the extent such records, reports and other information are not maintained by the Administrator, Shareholder Servicing Agent, Custodian or other agents.

The Adviser provides the Fund with office space, facilities and certain business equipment and provides the services of consultants, executive and clerical personnel for administering the affairs of the Fund. The Adviser compensates all executive and clerical personnel and Directors of The Needham Funds, Inc. if such persons are employees or affiliates of the Adviser or its affiliates.

The expenses borne by the Fund include: the charges and expenses of the shareholder servicing and dividend disbursing agent; custodian fees and expenses; legal and auditors' fees and expenses; brokerage commissions for portfolio transactions; taxes, if any; the advisory fee; extraordinary expenses (as determined by the Board of Directors of The Needham Funds, Inc.); expenses of shareholder and Director meetings, and of preparing, printing and mailing proxy statements, reports and other communications to shareholders; expenses of preparing and setting in type prospectuses and periodic reports and expenses of mailing them to current shareholders; expenses of registering and qualifying shares for sale (including compensation of the Adviser's employees in relation to the time spent on such matters); expenses relating to the Amended and Restated Plan of Distribution (the "Plan"); fees of Directors who are not "interested persons" of the Adviser; membership dues of the Investment Company Institute; fidelity bond and errors and omissions insurance premiums; the cost of maintaining the books and records of the Fund; and any other charges and fees not specifically enumerated as an obligation of the Distributor (as hereinafter defined) or Adviser.

13

The Advisory Agreement provides that the fee payable to the Adviser will be reduced to the extent expenses of the Fund exceed certain limits as specified in the Prospectus and those expenses are in excess of certain expense limitations if and as required by state regulation, and further that the Adviser will make any other necessary arrangements to limit expenses in accordance with applicable expense limitations unless the Fund has obtained an appropriate waiver of such expense limitations or expense items from a particular state authority. Under the Advisory Agreement, the maximum annual expenses which the Fund may be required to bear, inclusive of the advisory fee but exclusive of interest, taxes, brokerage fees, distribution payments made in accordance with the Plan and extraordinary items, may not exceed the lowest expense limitation imposed by any state in which the Fund is registered or the specified Prospectus expense limit, whichever is lower. The amount of the advisory fee to be paid to the Adviser each month will be reduced by the amount, if any, by which the annualized expenses of the Fund for that month exceed the foregoing limitations.

The advisory fee is accrued daily and paid monthly. For the 2001 fiscal year, if the aggregate annual expenses of the Fund exceed the amount permissible under the foregoing limitations, then the Adviser has agreed after the end of the 2001 fiscal year to promptly return such advisory fees previously received during such fiscal year equal to the total amount by which expenses exceed the amount of the limitations, and, if necessary, make any other arrangements necessary to maintain the Fund's expenses within such limitations. If aggregate annual expenses are within the limitations during fiscal 2001, however, any excess amount previously withheld will be paid to the Adviser.

The Advisory Agreement was approved by the Board of Directors of The Needham Funds, Inc. on behalf of the Fund, including a majority of the Directors who are not parties to the Advisory Agreement or interested persons of any such party. The Advisory Agreement provides that it shall continue in effect from year to year with respect to the Fund as long as it is approved at least annually (i) by a vote of a majority of the outstanding voting securities of the Fund (as defined in the 1940 Act) or (ii) by a vote of a majority of the Directors of The Needham Funds, Inc. including a vote of a majority of the Directors who are not parties to the Advisory Agreement or "interested persons" of any party thereto, cast in person at a meeting called for the purpose of voting on such approval. The Advisory Agreement may be terminated on 60 days' written notice by either party and will terminate automatically if it is assigned within the meaning of the 1940 Act.

THE DISTRIBUTOR AND DISTRIBUTION OF THE SHARES

Shares of the Fund are offered on a continuous basis and are currently distributed through Needham & Company, Inc., 445 Park Avenue, New York, New York 10022 (the "Distributor"). The Board of Directors of The Needham Funds, Inc. has approved a Distribution and Services Agreement (the "Distribution Agreement") appointing the Distributor as a distributor of shares of the Fund.

The Distribution Agreement provides that the Distributor will bear the cost and expense of printing and distributing any materials not prepared by the Fund and other materials used by the Distributor in connection with its offering shares of the Fund. The Fund will pay all fees and

14

expenses in connection with registering and qualifying its shares under federal and state securities laws.

To compensate the Distributor and other services providers for the distribution and/or shareholder-related services provided by them, the Fund has adopted the Plan pursuant to Rule 12b-1 under the 1940 Act. Fees paid by the Fund under the Plan will be used for promotional, distribution and shareholder-related services incurred only during the applicable year. Pursuant to the Plan, the service providers are required to provide the Fund at least quarterly with a written report of the amounts expended under the Plan and the purpose for which such expenditures were made. The Board of Directors reviews such reports on a quarterly basis.

The Plan has been approved by the Board of Directors of The Needham Funds, Inc., including a majority of the Directors who are not "interested persons" of The Needham Funds, Inc. and who have no direct or indirect financial interest in the operation of the Plan. The Plan continues in effect as to the Fund, provided such continuance is approved annually by a vote of the Directors in accordance with the 1940 Act. Information with respect to distribution revenues and expenses will be presented to the Directors each year for their consideration in connection with their deliberations as to the continuance of the Plan. In the review of the Plan, the Directors will be asked to take into consideration expenses incurred in connection with the distribution of shares. The Plan may not be amended to increase materially the amount to be spent for the services described therein without approval of the shareholders of the Fund, and all material amendments of the Plan must also be approved by the Directors in the manner described above. The Plan may be terminated at any time, without payment of any penalty, by vote of a majority of the Directors who are not "interested persons" of The Needham Funds, Inc. and who have no direct or indirect financial interest in the operation of the Plan, or by a vote of a majority of the outstanding voting securities of the Fund (as defined in the 1940 Act) on not more than 30 days' written notice to any other party to the Plan. The Plan will automatically terminate in the event of its assignment (as defined in the 1940 Act). So long as the Plan is in effect, the election and nomination of Directors who are not "interested persons" of The Needham Funds, Inc. shall be committed to the discretion of the Directors who are not "interested persons." The Directors have determined that, in their judgment, there is a reasonable likelihood that the Plan will benefit the Fund and its shareholders. The Fund will preserve copies of the Plan and any agreement or report made pursuant to Rule 12b-1 under the 1940 Act, for a period of not less than six years from the date of the Plan or such agreement or report, the first two years in an easily accessible place.

The Fund has entered or expects to enter into service agreements with, among others, the Distributor, Charles Schwab & Company, Inc. and National Financial Services Corp. Though the terms of the Fund's agreements vary, service providers generally are required to provide various shareholder services to the Fund, including records maintenance, shareholder communications, transactional services, tax information and reports, and facilitation of purchase and redemption orders. Payments generally are made under the Plan at the annual rate of 0.25% of the value of the Fund's shares held in accounts maintained by each such service provider. In the case of certain of the Fund's agreements, the Adviser is required to pay an additional 0.10% of the value of all Fund

15

shares held in their respective accounts. The Fund is required to make these payments to its service providers regardless of any actual expenses incurred by them.

TRANSFER AGENCY, ADMINISTRATION SERVICES,
FUND ACCOUNTING AND OTHER SERVICES

PFPC Inc. has been retained to perform shareholder servicing, registrar and transfer agent functions for the Fund pursuant to an agreement with The Needham Funds, Inc. PFPC Inc. has also been retained pursuant to a separate agreement to perform certain Fund and shareholder accounting and administrative functions. Subject to certain waivers from these services, the Fund pays a monthly fee at the annual rate of 0.10% on the first $200 million of average daily net assets of the Fund.

PORTFOLIO TRANSACTIONS AND BROKERAGE

The Adviser is responsible for decisions to buy and sell securities and other investments for the Fund, the selection of brokers and dealers to effect the transactions and the negotiation of brokerage commissions, if any. In transactions on stock and commodity exchanges in the U.S., these commissions are negotiated, whereas on foreign stock and commodity exchanges these commissions are generally fixed and are generally higher than brokerage commissions in the U.S. In the case of securities traded on the over-the-counter markets, there are generally no stated commissions, but the price usually includes an undisclosed commission or markup. In underwritten offerings, the price includes a disclosed, fixed commission or discount. The Fund may invest in obligations which are normally traded on a "principal" rather than agency basis. This may be done through a dealer (e.g., securities firm or bank) who buys or sells for its own account rather than as an agent for another client, or directly with the issuer. A dealer's profit, if any, is the difference, or spread, between the dealer's purchase and sale price for the obligation.

In purchasing and selling the Fund's portfolio investments, it is the Adviser's policy to obtain quality execution at the most favorable prices through responsible broker-dealers. In selecting broker-dealers, the Adviser will consider various relevant factors, including, but not limited to: the size and type of the transaction; the nature and character of the markets for the security or asset to be purchased or sold; the execution efficiency, settlement capability, and financial condition of the broker-dealer's firm; the broker-dealer's execution services rendered on a continuing basis; and the reasonableness of any commissions.

The Adviser may cause the Fund to pay a broker-dealer who furnishes brokerage and/or research services a commission that is in excess of the commission another broker-dealer would have received for executing the transaction if it is determined that such commission is reasonable in relation to the value of the brokerage and/or research services as defined in Section 28(e) of the Securities Exchange Act of 1934 which have been provided. Such research services may include, among other things, analyses and reports concerning issuers, industries, securities, economic factors

16

and trends, and portfolio strategy. Any such research and other information provided by brokers to the Adviser is considered to be in addition to and not in lieu of services required to be performed by the Adviser under the Advisory Agreement. The research services provided by broker-dealers can be useful to the Adviser in serving its other clients or clients of the Adviser's affiliates. The Board of Directors periodically reviews the Adviser's performance of its responsibilities in connection with the placement of portfolio transactions on behalf of the Fund and reviews the commissions paid by the Fund over representative periods of time to determine if they are reasonable in relation to the benefits to the Fund.

Investment decisions for the Fund are made independently from those of the other investment accounts managed by the Adviser or affiliated companies. Occasions may arise, however, when the same investment decision is made for more than one client's account. It is the practice of the Adviser to allocate such purchases or sales insofar as feasible among its several clients or the clients of its affiliates in a manner it deems equitable. The principal factors which the Adviser considers in making such allocations are the relative investment objectives of the clients, the relative size of the portfolio holdings of the same or comparable securities and the availability in the particular account of funds for investment. Portfolio securities held by one client of the Adviser may also be held by one or more of its other clients or by clients of its affiliates. When two or more of its clients or clients of its affiliates are engaged in the simultaneous sale or purchase of securities, transactions are allocated as to amount in accordance with formulae deemed to be equitable as to each client. There may be circumstances when purchases or sales of portfolio securities for one or more clients will have an adverse effect on other clients.

Consistent with the Rules of Fair Practice of the National Association of Securities Dealers, Inc. and subject to seeking the most favorable price and execution available and such other policies as the Board of Directors may determine, the Adviser may consider sales of shares of the Fund as a factor in the selection of broker-dealers to execute portfolio transactions for the Fund. In addition, the Fund may employ Needham & Company, Inc. (which is the Fund's Distributor) as a broker consistent with the rules under the 1940 Act and the Fund's Rule 17e-1 procedures.

While it is the policy of the Fund generally not to engage in trading for short-term gains, the Fund will effect portfolio transactions without regard to the holding period (subject to compliance with certain tax requirements for qualification as a regulated investment company) if, in the judgment of the Adviser, such transactions are advisable in light of a change in circumstances of a particular company, within a particular industry or country, or in general market, economic or political conditions. The Fund anticipates that in the year 2001 its annual portfolio turnover rate will be relatively insubstantial as the Fund will have been in operation for only a portion of the year. However, for the year 2002 the Fund anticipates that its annual portfolio turnover rate may be between 100% - 200%. The portfolio turnover rate of the Fund may vary significantly from year to year. The Fund may pay a greater amount in brokerage commissions than similar size funds with a lower turnover rate. In addition, since the Fund may have a high rate of portfolio turnover, the Fund may realize capital gains or losses. Capital gains will be distributed annually to the shareholders. Capital losses cannot be distributed to shareholders but may be used to offset capital

17

gains at the Fund level and carried forward for up to eight years to the extent there are no gains to offset for a particular year. See "Taxes" in this Statement of Additional Information.

PURCHASE AND REDEMPTION OF SHARES

Information relating to the purchase and redemption of shares of the Fund is located in the Prospectus.

NET ASSET VALUE

The net asset value per share of the Fund will be determined on each day when the New York Stock Exchange (the "Exchange") is open for business at the close of the Exchange and will be computed by determining the aggregate market value of all assets of the Fund less its liabilities, and then dividing that number by the total number of shares outstanding. The determination of net asset value for a particular day is applicable to all applications for the purchase of shares as well as all requests for the redemption of shares received before the close of trading on the Exchange on that day. Shares of the Fund are sold at the public offering price which is determined once each day the Fund is open for business and is the net asset value per share.

Portfolio securities positions for which market quotations are readily available are stated at the last sale price reported by the principal exchange for each such security as of the exchange's close of business. Securities for which no sale has taken place during the day and securities which are not listed on an exchange are valued at the mean of the current closing bid and asked prices. Foreign market closing prices are translated into U.S. dollar values at the mean of the bid and asked prices for the particular foreign currency as quoted on the valuation date. The value of a financial futures contract equals the unrealized gain or loss on the contract that is determined by marking it to the current settlement price for a like contract acquired on the day on which the commodity futures contract is being valued. A settlement price may not be used if the market makes a limit move with respect to the financial futures contract. In cases where securities are traded on more than one exchange, the securities are valued on the exchange designated by or under the authority of the Board of Directors as the primary market.

20

Short-term investments denominated in U.S. dollars that will mature in 60 days or less are stated at amortized cost; short-term investments denominated in foreign currencies are stated at amortized cost as determined in the foreign currency, translated to U.S. dollars at the current day's exchange rate. All other securities and assets for which market quotations are not readily available are valued at their fair value as determined in good faith by the Board of Directors, although the actual calculations may be made by persons acting pursuant to the direction of the Board of Directors. The assets of the Fund may also be valued on the basis of valuations provided by a pricing service approved by the Board of Directors.

Generally, trading in foreign securities and futures contracts, as well as corporate bonds, United States Government securities and money market instruments, is substantially completed each day at various times prior to the close of the Exchange. The values of such securities used in determining the net asset value of the shares of the Fund may be computed as of such times. Foreign currency exchange rates are also generally determined prior to the close of the Exchange. Occasionally, events affecting the value of such securities and such exchange rates may occur between such times and the close of the Exchange which will not be reflected in the computation of the Fund's net asset value. If events materially affecting the value of such securities occur during such period, then these securities will be valued at their fair market value as determined in good faith by the Directors.

PERFORMANCE INFORMATION

In the future, the Fund may advertise its performance in terms of average annual total return for 1, 5 and 10 year periods, or for such lesser periods as the Fund has been in existence. Average annual total return which may be used in such advertising is calculated according to the following formula:

n P(1+T) = ERV

Where:    P     =    a hypothetical initial payment of $1,000
          T     =    average annual total return
          n     =    number of years
          ERV   =    ending redeemable  value of a  hypothetical  $1,000 payment
                     made at the beginning of the 1, 5 or 10 year periods at the
                     end of the year or period.

Under the foregoing formula, the time periods used in any advertising will be based on rolling calendar quarters, updated to the last day of the most recent quarter prior to submission of the advertising for publication. Average annual total return, or "T" in the above formula, is computed by finding the average annual compounded rates of return over the period that would equate the initial amount invested to the ending redeemable value. Average annual total return assumes the reinvestment of all dividends and distributions.

21

The calculation assumes an initial $1,000 payment and assumes all dividends and distributions by the Fund are reinvested at the price stated in the Prospectus on the reinvestment dates during the period, and includes all recurring fees that are charged to all shareholder accounts.

A Fund may also calculate total return on a cumulative basis which reflects the cumulative percentage change in value over the measuring period. The formula for calculating cumulative total return can be expressed as follows:

Cumulative Total Return = [ (ERV)/P - 1 ]

OTHER INFORMATION

The Fund's performance data quoted in any advertising and other promotional materials represents past performance and is not intended to predict or indicate future results. The return and principal value of an investment in the Fund will fluctuate and an investor's redemption proceeds may be more or less than the original investment amount.

COMPARISON OF FUND PERFORMANCE

The performance of the Fund may be compared to data prepared by Lipper Analytical Services, Inc., Morningstar, Inc. or other independent services which monitor the performance of investment companies and may be quoted in advertising in terms of its ranking in each applicable universe. In addition, the Fund may use performance data reported in financial and industry publications, including, but not limited to, Barron's, Business Week, Forbes, Fortune, Investor's Business Daily, IBC/Donoghue's Money Fund Report, Money Magazine, The Wall Street Journal and USA Today.

The Fund may from time to time use the following unmanaged indices for performance comparison purposes:

S&P 500 Index -- the S&P 500 Index is an index of 500 stocks designed to mirror the overall equity market's industry weighting. Most, but not all, large capitalization stocks are in this index. There are also some small capitalization names in this index. This index is maintained by Standard & Poor's Corporation. It is market capitalization weighted. There are always 500 issuers in the S&P 500 Index. Changes are made by Standard & Poor's as needed.

This index is market capitalization weighted and is maintained by the Frank Russell Company. There are always 2,000 issuers in the Russell 2000 Index. The Frank Russell Company reconstitutes this index annually.

22

NASDAQ Composite Index -- the NASDAQ Composite Index is a broad-based capitalization-weighted index of all NASDAQ National Market & Small Cap stocks.

TAX-SHELTERED RETIREMENT PLANS

The Fund offers certain tax-sheltered retirement plans through which shares may be purchased, including IRAs (and "rollovers" from existing retirement plans) for individuals and their spouses, SEP-IRAs and Roth IRAs. Shares of the Fund may also be purchased by Qualified Retirement Plans, such as profit-sharing and money purchase plans, 401(k) Plans and other Defined Contribution Plans, and by Defined Benefit Plans. Persons who wish to establish a tax-sheltered retirement plan should consult their own tax advisers or attorneys regarding their eligibility to do so and the laws applicable thereto, such as the fiduciary responsibility provisions and diversification requirements and the reporting and disclosure obligations under the Employee Retirement Income Security Act of 1974. The Fund is not responsible for compliance with such laws. Further information regarding the retirement plans, including applications and fee schedules, may be obtained upon request to the Fund.

TAXES

TAXATION OF THE FUND -- IN GENERAL

The Fund intends to qualify each year and elect to be taxed as a "regulated investment company" under Subchapter M of the United States Internal Revenue Code of 1986, as amended (the "Code"). By so qualifying, the Fund generally will not be subject to Federal income tax on that part of its investment company taxable income (consisting generally of net investment income, income from certain foreign currency transactions and any excess of net short-term capital gains over net long-term capital loss) and net capital gain that is annually distributed to its shareholders. The Fund intends to continue to so qualify and elect to be treated as a regulated investment company so long as to do so is in the best interests of its shareholders. To so qualify, the Fund, among other things, must (i) derive at least 90% of its gross income from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock, securities or foreign currencies, or certain other income (including gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies; and (ii) (a) have at least 50% of the market value of the Fund's assets represented by cash, U.S. government securities and other securities limited in respect of any one issuer to an amount not greater than 5% of the Fund's assets and 10% of the outstanding voting securities of such issuer, and (b) not have more than 25% of the value of its assets invested in the securities of any one issuer (other than U.S. government securities and the securities of other regulated investment companies).

In addition, the Fund must satisfy the distribution requirements of the Code, including the requirement that it distribute at least 90% of its "investment company taxable income" annually. By

23

qualifying (and electing to be treated) as a regulated investment company, the Fund will not be subject to federal income tax on its investment company taxable income and net capital gain that it distributes to shareholders. However, if for any taxable year the Fund does not satisfy the requirements of Subchapter M of the Code, all of its taxable income will be subject to tax at regular corporate rates without any deduction for distributions to shareholders, and such distributions will be taxable to shareholders as ordinary dividend income to the extent of Fund's current or accumulated earnings or profits.

The Fund will be liable for a non-deductible 4% excise tax on amounts not distributed on a timely basis in accordance with a calendar year distribution requirement. To avoid the tax, during each calendar year the Fund must distribute (i) at least 98% of its ordinary income realized during such calendar year, (ii) at least 98% of its capital gain net income for the twelve month period ending on October 31 (or December 31, if the Fund so elects), and (iii) any income or gain from the prior year that was neither distributed to shareholders nor taxed to the Fund for such year. The Fund intends to make sufficient distributions to avoid this 4% excise tax.

As long as the Fund qualifies as a regulated investment company for U.S. federal income tax purposes and distributes all of its investment company taxable income and net capital gain, it will not be subject to any corporate income or excise taxes in the State of Maryland.

TAXATION OF THE FUND'S INVESTMENTS

Ordinarily, gains and losses realized from portfolio transactions are treated as capital gain or loss. However, all or a portion of the gain or loss from the disposition of non-U.S. dollar denominated securities (including debt instruments, certain financial forward, futures and option contracts, and certain preferred stock) may be treated as ordinary income or loss under Section 988 of the Code. In addition, all or a portion of the gain realized from the disposition of market discount bonds is treated as ordinary income under Section 1276 of the Code. Generally, a market discount bond is defined as any bond bought by the Fund after its original issuance at a price below its principal amount. In addition, all or a portion of the gain realized from engaging in "conversion transactions" is treated as ordinary income under Section 1258 of the Code. "Conversion transactions" are defined to include certain forward, futures, option and straddle transactions, transactions marketed or sold to produce capital gains, or transactions described in applicable Treasury regulations. Also, gains or losses attributable to fluctuations in foreign currency exchange rates which occur between the time the Fund accrues income or other receivables or accrues expenses or other liabilities denominated in a foreign currency and the time the Fund actually collects such receivables or pays such liabilities generally are treated as ordinary income or ordinary loss.

Under Section 1256 of the Code, any gain or loss the Fund realizes from certain futures or forward contracts and options transactions is treated as 60% long-term capital gain or loss and 40% short-term capital gain or loss. Absent an election to the contrary, gain or loss arises upon exercise or lapse of such contracts and options as well as from closing transactions. In addition, any such

24

contracts or options remaining unexercised at the end of the Fund's taxable year are treated as sold for their then fair market value, resulting in additional gain or loss to the Fund characterized in the manner described above.

Offsetting positions held by the Fund involving certain financial forward, futures or options contracts (including certain foreign currency forward contracts or options) may constitute "straddles." "Straddles" are defined to include "offsetting positions" in actively traded personal property. The tax treatment of "straddles" is governed by Sections 1092 and 1258 of the Code, which, in certain circumstances, override or modify the provisions of Sections 1256 and 988 of the Code. If the Fund were treated as entering into "straddles" by reason of its engaging in certain forward contracts or options transactions, such "straddles" generally would be characterized as "mixed straddles" if the forward contracts or options transactions comprising a part of such "straddles" were governed by Section 1256 of the Code. However, the Fund may make one or more elections with respect to "mixed straddles." Depending on which election is made, if any, the results to the Fund may differ. If no election is made, to the extent the "straddle" rules apply to positions established by the Fund, losses realized by the Fund will be deferred to the extent of unrealized gain in the offsetting position. Moreover, as a result of the "straddle" rules, short-term capital loss on "straddle" positions may be recharacterized as long-term capital loss, and long-term capital gains may be treated as short-term capital gains or ordinary income.

If the Fund makes a "constructive sale" of an "appreciated financial position," the Fund will recognize gain but not loss as if the position were sold at fair market value on the date of such constructive sale. Constructive sales include short sales of substantially identical property, offsetting notional principal contracts with respect to substantially identical property and futures and forward contracts to deliver substantially identical property. However, transactions that otherwise would be treated as constructive sales are disregarded if closed within 30 days after the close of the taxable year and the Fund holds the position and does not hedge such position for 60 days thereafter. In addition, to the extent provided in regulations (which have not yet been promulgated), a constructive sale also occurs if a taxpayer enters into one or more other transactions (or acquires one or more positions) that have "substantially the same effect" as the transactions described above. Appreciated financial positions include positions with respect to stock, debt, instruments or partnership interests if gain would be recognized on a disposition at fair market value. If the constructive sale rules apply, adjustments are made to the basis and holding period of the affected financial position, and the Fund would recognize gain but would not have cash available to make distributions. Accordingly, the gain realized under the constructive sale provisions would impact on the amount of distributions required by the Fund so as to avoid the imposition of the 4% excise tax.

If the Fund invests in any non-U.S. corporation that either satisfies (i) the "passive income test" (e.g., receives at least 75% of its annual gross income from passive sources, such as interest, dividend, rental, royalty or capital gain income) or (ii) the "passive asset test" (e.g., at least 50% of its assets on average consist of assets which produce or are held for the production of passive income) ("passive foreign investment company" or "PFIC") and that does not distribute its income on a regular basis, the Fund could be subject to federal income tax and additional interest charges

25

on "excess distributions" received from such company or gain from the sale of stock in such company, even if all income or gain actually received by the Fund is timely distributed to its shareholders. In addition, any gain on sale of PFIC stock would be treated as ordinary income. The Fund would not be able to pass through to its shareholders any credit or deduction for such a tax. If the Fund were to invest in the stock of a passive foreign investment company and elect to treat such company as a "qualified electing fund" under the Code (and the company agreed to adhere to certain information reporting requirements), in lieu of the foregoing consequences, the Fund would be required to include in income each year a portion of the ordinary earnings and net capital gains of the qualified electing fund, even if not distributed to the Fund, and such amounts would be subject to the 90% and calendar year distribution requirements described above even if the Fund received no money to distribute. To satisfy those distribution requirements, the Fund would have to use cash from other sources, including proceeds from the disposition of its assets. As an alternative to a qualified electing fund election, the Fund generally could elect to mark-to-market shares of a publicly traded PFIC and thereby avoid the application of the excess distribution rules. However, the gain realized under such approach would impact upon the amount of distributions required by the Fund so as to avoid the imposition of the 4% excise tax (because no cash would be available from such mark-to-market transaction with which to make any such distribution). Accordingly, the Fund will limit its investments in such passive foreign investment companies and will undertake appropriate actions to limit its tax liability, if any, with respect to such investments.

TAXATION OF THE SHAREHOLDERS

Distributions of net investment income and the excess of net short-term capital gain over net long-term capital loss are taxable as ordinary income to shareholders. The Fund may also make distributions of net capital gain (the excess of net long-term capital gain over net short-term capital loss). In general, a noncorporate shareholder's net capital gains will be taxed at a maximum rate of 20% for property held more than one year, and the maximum rate is reduced to 18% for property acquired after December 31, 2000 and held for more than five years. The Fund will provide information relating to the portions of any net capital gain distribution that may be treated by noncorporate shareholders as eligible for the maximum long-term capital gains rate. Such treatment would apply regardless of the length of time the shares of the Fund have been held by such shareholders. Any loss realized upon a taxable disposition of shares within six months from the date of their purchase is treated as a long-term capital loss to the extent of any long-term capital gain distributions received by shareholders during such period.

Distributions of net investment income and capital gain net income are taxable as described above whether received in cash or reinvested in additional shares. A shareholder's tax basis in each share received from the Fund is equal to the fair market value of such share on the payment date.

Distributions by the Fund result in a reduction in the net asset value of the Fund's shares. Should a distribution reduce the net asset value below a shareholder's tax basis, such distribution nevertheless is taxable to the shareholder as ordinary income or long-term capital gain as described above, even though, from an investment standpoint, it may constitute a partial return of capital. In

26

particular, investors should be careful to consider the tax implications of buying shares just prior to a distribution. The price of shares purchased at that time includes the amount of any forthcoming distribution. Those investors purchasing shares just prior to a distribution receive a return of investment upon such distribution which is nevertheless taxable to them.

A redemption of Fund shares by a shareholder will result in the recognition of taxable gain or loss depending upon the difference between the amount realized and his tax basis in his Fund shares. Generally, such gain or loss is treated as a capital gain or loss if the shares are held as capital assets. In the case of a noncorporate shareholder, if such shares were held for more than one year at the time of disposition such gain will be long-term capital gain and if such shares were held for one year or less at the time of disposition such gain will be short-term capital gain and will be taxed at the applicable ordinary income tax rate. In addition, any loss realized upon a taxable disposition of shares within six months from the date of their purchase is treated as a long-term capital loss to the extent of long-term capital gain distributions received from the Fund during such six-month period. Finally, all or a portion of any loss realized upon a taxable disposition of Fund shares may be disallowed if other shares of the same Fund are purchased (including a purchase by automatic reinvestment) within 30 days before or after such disposition. In such a case, the tax basis of the shares acquired is adjusted to reflect the disallowed loss. Dividends from domestic corporations may comprise some portion of the Fund's gross income. To the extent that such dividends constitute a portion of the Fund's gross income, a portion of the income distributions received by corporations from the Fund may be eligible for the 70% deduction for dividends received. Taxable corporate shareholders will be informed of the portion of dividends which so qualify. Receipt of qualifying dividends may result in the reduction of a corporate shareholder's tax basis in its shares by the untaxed portion of such dividends if they are treated as "extraordinary dividends" under Section 1059 of the Code. The dividends-received deduction is reduced to the extent the shares of the Fund with respect to which the dividends are received are treated as debt-financed under federal income tax law and is eliminated if the shares are deemed to have been held for less than 46 days (91 days for preferred stock) during the 90-day period (180-day period for preferred stock) beginning on the date which is 45 days (90 days for preferred stock) before the ex-dividend date (for this purpose, holding periods are reduced for periods where the risk of loss with respect to shares is diminished). The same restrictions apply to the Fund with respect to its ownership of the dividend-paying stock. In addition, the deducted amount is included in the calculation of the federal alternative minimum tax, if any, applicable to such corporate shareholders. In contrast, distributions of net capital gains are not eligible for the dividends-received deduction for corporate shareholders.

Income received by the Fund may give rise to withholding and other taxes imposed by foreign countries. If more than 50% of the value of the Fund's assets at the close of a taxable year consists of securities of foreign corporations, the Fund may make an election that will permit shareholders in lieu of the Fund to take a credit (or, if more advantageous, a deduction) for foreign income taxes paid by the Fund, subject to limitations contained in the Code. Investors would then include in gross income both dividends paid to the shareholders and the foreign taxes paid by the Fund on its foreign investments. The Fund cannot assure investors that they will be eligible for the

27

foreign tax credit. The Fund will advise the shareholders annually of their share of any creditable foreign taxes paid by the Fund.

Taxation of a shareholder who, as to the U.S., is a nonresident alien individual, foreign trust or estate, foreign corporation or foreign partnership (a "Foreign Shareholder"), as defined in the Code, depends, in part, on whether the Foreign Shareholder's income from the Fund is "effectively connected" with a U.S. trade or business carried on by such shareholder.

If the Foreign Shareholder is a nonresident alien and the income from the Fund is not effectively connected with a U.S. trade or business carried on by the Foreign Shareholder, Fund distributions other than net capital gains distributions and distributions not out of earnings and profits are subject to a 30% (or lower treaty rate) U.S. withholding tax. Furthermore, such Foreign Shareholders are subject to an increased U.S. tax on their income if the Fund elects (as described above) to "pass through" amounts of foreign taxes paid by the Fund due to the fact that such Foreign Shareholders are not able to claim a credit or deduction with respect to the foreign taxes treated as having been paid by them. Net capital gain distributions to, and capital gains realized by, such a Foreign Shareholder upon the sale of shares or receipt of distributions which are in excess of its tax basis and not made from earnings and profits are not subject to U.S. tax unless the Foreign Shareholder is an individual and is present in the U.S. for 183 days or more during the taxable year in which the gain was realized, and certain other conditions are satisfied. A Foreign Shareholder will be required to satisfy certification requirements in order to claim treaty benefits or otherwise claim a reduction of or exemption from withholding under the foregoing rules. These requirements will require identification of the holder and must be made under penalties of perjury. A Foreign Shareholder that is eligible for a reduced rate of U.S. withholding tax pursuant to a tax treaty may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the IRS.

Federal regulations generally require the Fund to withhold ("backup withholding") and remit to the U.S. Treasury 31% of dividends, distributions from net realized securities gains and the proceeds of any redemption, regardless of the extent to which gain or loss may be realized, paid to shareholders if they fail to certify either that the Taxpayer Identification Number ("TIN") furnished in connection with the opening of an account is correct or that shareholders have not received notice from the IRS of being subject to backup withholding as a result of failure to properly report taxable dividend or interest income on a federal income tax return. Furthermore, the IRS may notify the Fund to institute backup withholding if the IRS determines a shareholder's TIN is incorrect or if a shareholder failed to properly report taxable dividend and interest income on a federal tax return.

If a shareholder is a resident alien or if dividends or distributions from the Fund are effectively connected with a U.S. trade or business carried on by the shareholder, then Fund distributions and any gains realized with respect to the shares are subject to U.S. federal income tax at the rates applicable to U.S. citizens or residents or domestic corporations, as appropriate.

28

The value of shares held by an individual Foreign Shareholder, even though he is a nonresident at his death, is includible in his gross estate for U.S. federal estate tax purposes.

The tax consequences to a Foreign Shareholder entitled to claim the benefits of an applicable tax treaty may be different from those described above. Such shareholders may be required to provide appropriate documentation to establish their entitlement to the benefits of such a treaty. Foreign Shareholders are advised to consult their own tax advisers with respect to (i) whether their income from the Fund is or is not effectively connected with a U.S. trade or business carried on by them, (ii) whether they may claim the benefits of an applicable tax treaty, and (iii) any other tax consequences to them of an investment in the Fund.

The foregoing discussion is a general summary of certain of the material U.S. federal income tax consequences of owning and disposing of shares in the Fund. This summary is based on the provisions of the Code, final, temporary and proposed U.S. Treasury Regulations promulgated thereunder, and administrative and judicial interpretations thereof, all as in effect on the date hereof, and all of which are subject to change, possibly with retroactive effect.

The foregoing discussion is a general summary of certain of the current federal income tax laws affecting the Fund and investors in the shares. The discussion does not purport to deal with all of the federal income tax consequences applicable to the Fund, or to all categories of investors, some of which may be subject to special rules. Investors should consult their own advisors regarding the tax consequences, including state and local tax consequences to them of investment in the Fund. Foreign Shareholders should also consult their tax advisers with respect to the applicability of a 30% withholding tax (which may be reduced or eliminated under certain income tax treaties) upon Fund distributions of ordinary income.

This summary does not deal with all aspects of U.S. federal income taxation that may be relevant to particular shareholders in light of their particular circumstances. Accordingly, shareholders should consult their tax advisers about the application of the provisions of tax law described in this Statement of Additional Information in light of their particular tax situations.

ITEM 24. PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH REGISTRANT

Each of George A. Needham and John C. Michaelson may be deemed to be control persons of Needham & Company, Inc. based upon their positions as officers, directors and/or stockholders of that entity.

ITEM 25. INDEMNIFICATION

Section 2-418 of the General Corporation Law of the State of Maryland, the state in which The Needham Funds, Inc. was organized, empowers a corporation, subject to certain limitations, to indemnify its directors, officers, employees and agents against expenses (including attorneys' fees, judgments, penalties, fines and settlements) actually and reasonably incurred by them in connection with any suit or proceeding to which they are a party so long as they acted in good faith or without active and deliberate dishonesty, or they received no actual improper personal benefit in money, property or services, if, with respect to any criminal proceeding, so long as they had no reasonable cause to believe their conduct to have been unlawful.

Article X of the Bylaws of The Needham Funds, Inc. provides for indemnification.

The directors and officers of The Needham Funds, Inc. are insured against losses arising from any claim against them as such for wrongful acts or omissions, subject to certain limitations.

The Needham Funds, Inc. will comply with applicable indemnification requirements as set forth in releases under the 1940 Act.


Insofar as indemnification for liabilities arising under the 1933 Act may be permitted to directors, officers and controlling persons of The Needham Funds, Inc., pursuant to the foregoing provisions, or otherwise, The Needham Funds, Inc. 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 Needham Funds, Inc. of expenses incurred or paid by a director, officer or controlling person of The Needham Funds, Inc. in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, The Needham Funds, Inc. 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.

Pursuant to the requirements of the Securities Act of 1933 and the Investment Company Act of 1940, the Registrant has duly caused this Amendment to the Registration Statement to be signed on its behalf by the undersigned, thereto duly authorized, in the City of New York, State of New York, on the 15th day of June, 2001.

THE NEEDHAM FUNDS, INC.

By: /s/ John C. Michaelson
    ----------------------------------
        John C. Michaelson

THE NEEDHAM FUNDS, INC.
DISTRIBUTION AND SERVICES AGREEMENT

AGREEMENT made as of the _____ day of August, 2001, between The Needham Funds, Inc., a Maryland corporation (the "Company"), and Needham & Company, Inc., a Delaware corporation (the "Distributor"), such Distributor to act in the manner contemplated by this Agreement.

WITNESSETH:

WHEREAS, the Company is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as a series, open-end management investment company;

WHEREAS, the Company and the Distributor wish to enter into an agreement with each other with respect to the continuous offering of shares (the "Shares") of the Company's portfolios, as are listed on Exhibit A hereto, as such exhibit may from time to time be amended as set forth herein (each a "Fund" and, collectively, the "Funds").

NOW, THEREFORE, the parties agree as follows:

Section 1. APPOINTMENT OF THE DISTRIBUTOR. The Company hereby appoints the Distributor the non-exclusive agent for each of the Funds to sell and to arrange for the sale of the Shares, including both issued and treasury shares, on the terms and for the period set forth in this Agreement, and the Distributor hereby accepts such appointment and agrees to act hereunder.


Section 2. SERVICES AND DUTIES OF THE DISTRIBUTOR.

(a) The Distributor agrees to sell, as agent for each of the Funds, from time to time during the term of this Agreement, Shares (whether unissued or treasury shares, in each Fund's sole discretion) upon the terms described in the prospectus of the applicable Fund (the "Prospectus"). As used in this Agreement, the term "Prospectus" shall mean the Prospectus and Statement of Additional Information included as part of the Company's registration statement on Form N-1A, as such Prospectus and Statement of Additional Information may be amended or supplemented from time to time, and the term "Registration Statement" shall mean the Registration Statement on Form N-1A most recently filed by the Company with the Securities and Exchange Commission and effective under the Securities Act of 1933, as amended (the "1933 Act"), and the 1940 Act, as such Registration Statement is amended by any amendments thereto at the time in effect.

(b) The Distributor will hold itself available to receive orders, satisfactory to the Distributor, for the purchase of Shares and will accept such orders as of the time of payment for those orders and will transmit such orders as are so accepted to the Company's transfer and dividend disbursing agent as promptly as practicable. Purchase orders shall be deemed effective at the time and in the manner set forth in the Prospectus.

(c) The Distributor in its discretion may sell Shares to such registered and qualified retail dealers as it may select. In making agreements with such dealers, the Distributor shall act only as principal and not as agent for the Company or any of the Funds.

(d) The offering price of the Shares shall be the net asset value (as defined in the Articles of Incorporation of the Company and determined as set forth in the Prospectus) next

-2-

determined following receipt of payment. Each Fund shall furnish the Distributor, with all possible promptness, an advice of each computation of net asset value.

(e) The Distributor shall not be obligated to sell any certain number of Shares and nothing herein contained shall prevent the Distributor from entering into like distribution arrangements with other investment companies so long as the performance of its obligations hereunder is not impaired thereby.

Section 3. COMPENSATION OF THE DISTRIBUTOR.

(a) As promptly as possible after the first business day of each month this Distribution Agreement is in effect, each Fund shall pay to the Distributor for its distribution and services expenditures and activities hereunder made or performed during the previous month at the annual rate of .25% of the average daily net assets of the Fund which are related to the Distributor's activities hereunder; provided that payment shall be made in any month only to the extent that such payment, together with any other payments made by the Fund pursuant to its Plan (as defined herein) to the Distributor or others, shall not exceed an annual rate of .25% of the average daily net assets of the Fund for that month. The payments by the Fund made pursuant to this Agreement to the Distributor are authorized pursuant to the plan adopted by the Board of Directors of the Company on behalf of each Fund under Rule 12b-1 under the 1940 Act (the "Plan").

(b) For purposes of this Agreement, "distribution expenditures and service activities" of the Distributor shall mean all expenditures and activities of the Distributor primarily intended to result in the sale of Shares, including, but not limited to, the following: (i) compensation to personnel of the Distributor and to securities dealers and other financial institutions and organizations for various distribution related services for each Fund; (ii) expenditures for support

-3-

services such as telephone facilities and expenses and shareholder services as each Fund may reasonably request; (iii) formulation and implementation of marketing and promotional activities, including, but not limited to, direct mail promotions and television, radio, newspaper, magazine and other mass media advertising; (iv) preparation, printing and distribution of sales literature;
(v) preparation, printing and distribution of the Prospectus for recipients other than existing shareholders of each Fund; (vi) provision to each Fund of such information, analyses and opinions, with respect to marketing and promotional activities as each Fund may, from time to time, reasonably request; and (vii) payment of capital or other expenses associated with the foregoing including equipment, rent, salaries, bonuses or other overhead costs.

(c) The Distributor shall prepare and deliver such reports to the Treasurer of the Company as may be required by the Plan.

Section 4. DUTIES OF THE FUNDS.

(a) Each Fund agrees to sell the Shares so long as it has shares available for sale and to deliver certificates for, or cause the Company's transfer and dividend disbursing agent to issue non-negotiable share deposit receipts evidencing, such shares registered in such names and amounts as the Distributor has requested in writing, as promptly as practicable after receipt by the Fund of the net asset value thereof and written request of the Distributor therefor.

(b) Each Fund shall keep the Distributor fully informed with regard to its affairs and shall furnish to the Distributor copies of all information, financial statements and other papers which the Distributor may reasonably request for use in connection with the distribution of Shares of each Fund, including one certified copy, upon request by the Distributor, of all financial statements prepared for each Fund by independent accountants and such reasonable number of copies

-4-

of the most current Prospectus as the Distributor may request, and each Fund shall cooperate fully in the efforts of the Distributor to sell and arrange for the sale of the Fund's Shares and in the performance of the Distributor under this Agreement.

(c) Each Fund shall take, from time to time, all necessary action to fix the number of authorized shares and such steps, including payment of the related filing fee, as may be necessary to register the same under the 1933 Act and the 1940 Act to the end that there will be available for sale such number of Shares as the Distributor may be expected to sell. The Company agrees to file from time to time such amendments, reports and other documents as may be necessary to ensure that there will be no untrue statement of a material fact in a Registration Statement or Prospectus, or that there will be no omission to state a material fact in the Registration Statement or Prospectus which omission would make the statements therein misleading.

(d) Each Fund shall use its best efforts to qualify and maintain the qualification of an appropriate number of the Shares for sale under the securities laws of such states as the Distributor and the Company may approve; provided however, that the Company shall not be required to amend its Articles of Incorporation or By-Laws to comply with the laws of any state, to maintain an office in any state, to change the terms of the offering of Shares in any state from the terms set forth in its Registration Statement and Prospectus, to qualify as a foreign corporation in any state or to consent to service of process in any state other than with respect to claims arising out of the offering of the Shares. The Distributor shall furnish such information and other material relating to its affairs and activities as may be required in connection with such qualifications.

-5-

Section 5. EXPENSES.

(a) Each Fund shall bear all costs and expenses of the continuous offering of its Shares in connection with: (i) fees and disbursements of its counsel and independent accountants, (ii) the preparation, filing and printing of the Registration Statement and/or Prospectus required under the federal securities laws, (iii) the preparation and mailing of annual and interim reports, prospectuses and proxy materials to existing shareholders and (iv) the qualifications of Shares for sale under the securities laws of such states or other jurisdictions as shall be selected by the Company and the Distributor pursuant to Section 4(d) hereof and the cost and expenses payable to each such state for continuing qualification therein.

(b) The Distributor shall bear (i) the costs and expenses of preparing, printing and distributing any materials not prepared by any Fund and other materials used by the Distributor in connection with its offering of Shares for sale to the public, (ii) the expenses of registration or qualification of the Distributor as a dealer or broker under federal or state laws and the expenses of continuing such registration or qualification and (iii) the expenses of any sales commissions for sales of the Shares (except such expenses as are specifically undertaken herein by each Fund).

Section 6. INDEMNIFICATION. Each Fund agrees to indemnify, defend and hold the Distributor, its officers and directors and any person who controls the Distributor within the meaning of Section 15 of the 1933 Act, free and harmless from and against any and all claims, demands, liabilities and expenses (including the cost of investigating or defending such claims, demands or liabilities and any counsel fees incurred in connection therewith) which the Distributor, its officers, directors or any such controlling person may incur under the 1933 Act, or under common law or otherwise, arising out of or based upon any untrue statement of a material fact contained in the

-6-

Registration Statement or Prospectus or arising out of or based upon any alleged omission to state a material fact required to be stated in either thereof or necessary to make the statements in either thereof not misleading, except insofar as such claims, demands, liabilities or expenses arise out of or are based upon any such untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information furnished in writing by the Distributor to the Company for use in the Registration Statement or Prospectus; provided, however, that this indemnity agreement shall not inure to the benefit of such officer, director or controlling person unless a court of competent jurisdiction shall determine, in a final decision on the merits, that the person to be indemnified was not liable, by reason of willful misfeasance, bad faith, or gross negligence, in the performance of its duties, or by reason of its reckless disregard of its obligations under this Agreement ("disabling conduct"), or, in the absence of such a decision, a reasonable determination, based upon a review of the facts, that the indemnified person was not liable by reason of disabling conduct, by (a) a vote of a majority of a quorum of directors of the Company who are neither "interested persons" of the Company as defined in Section 2(a)(19) of the 1940 Act nor parties to the proceeding, or
(b) an independent legal counsel in a written opinion. Each Fund's agreement to indemnify the Distributor, its officers and directors and any such controlling person as aforesaid is expressly conditioned upon each Fund being promptly notified of any action brought against the Distributor, its officers or directors, or any such controlling person, such notification to be given by letter or telegram addressed to the Fund at its principal business office. Each Fund agrees to promptly notify the Distributor of the commencement of any litigation or proceedings against it or any of its officers or directors in connection with the issue and sale of any of its Shares.

-7-

The Distributor agrees to indemnify, defend and hold each Fund and the Company, its officers and directors and any person who controls any Fund or the Company, if any, within the meaning of Section 15 of the 1933 Act, free and harmless from and against any and all claims, demands, liabilities and expenses (including the cost of investigating or defending against such claims, demands or liabilities and any counsel fees incurred in connection therewith) which any of the above may incur under the 1933 Act or under common law or otherwise, but only to the extent that such liability or expense incurred by any of the above resulting from such claims or demands shall arise out of or be based upon any alleged untrue statement of a material fact contained in information furnished in writing by the Distributor to the Company for use in the Registration Statement or Prospectus or shall arise out of or be based upon any alleged omission to state a material fact in connection with such information required to be stated in the Registration Statement or Prospectus or necessary to make such information not misleading. The Distributor's agreement to indemnify the Funds and the Company, its directors and officers, and any such controlling person as aforesaid is expressly conditioned upon the Distributor's being promptly notified of any action brought against any of the above, such notification being given to the Distributor at its principal business office.

Section 7. COMPLIANCE WITH SECURITIES LAWS. The Company represents that it is registered as an open-end management investment company under the 1940 Act, and agrees that it will comply with all of the provisions of the 1940 Act and of the rules and regulations thereunder.

-8-

all applicable state securities laws. The Distributor agrees to comply with all of the applicable terms and provisions of the Securities Exchange Act of 1934.

Section 8. EFFECTIVENESS, DURATION AND TERMINATION OF THIS AGREEMENT. This Agreement shall become effective with respect to each Fund upon approval by a majority of both (a) the Board of Directors of the Company and (b) the Directors who are not interested persons of the Company and who have no direct or indirect financial interest in the operation of this Agreement or the Plan or any agreements related to it, cast in person at a meeting called for the purpose of voting upon such approval. This Agreement shall continue in effect for a period of more than one year from the effective dates only for so long as such continuance specifically approved annually in the manner provided above.

This Agreement may be terminated at any time, with respect to any Fund, without the payment of any penalty, by the Board of Directors of the Company, by a majority of the Directors of the Company who are not interested persons of the Company and who have no direct or indirect financial interest in this Agreement or the Plan or by vote of a majority of the outstanding voting Shares of any Fund, or by the Distributor, on not more than sixty (60) days' nor less than thirty (30) days' written notice to the other party. This Agreement shall automatically terminate in the event of its assignment (as defined in the 1940 Act).

Section 9. AMENDMENTS OF THIS AGREEMENT. With respect to each Fund, this Agreement may be amended by the parties only if such amendment is specifically approved by (i) the Board of Directors of the Company or by the vote of a majority of outstanding voting Shares of the respective Fund, and (ii) a majority of those directors of the Company who are not parties to this Agreement or interested persons of any such party and who have no direct or indirect financial

-9-

interest in this Agreement, cast in person at a meeting called for the purpose of voting on such approval.

Re: REGISTRATION STATEMENT ON FORM N-1A
SECURITIES ACT FILE NO. 33-98310
INVESTMENT COMPANY ACT FILE NO. 811-9114

Gentlemen:

We are furnishing this opinion in connection with Post-Effective Amendment No. 9 to the Registration Statement on Form N-1A (the "Registration Statement") of The Needham Funds, Inc. (the "Company"), a Maryland corporation, filed with the Securities and Exchange Commission under the Securities Act of 1933 (File No. 33-98310) and the Investment Company Act of 1940 (File No. 811- 9114), for the registration of an indefinite number of shares of common stock (the "Shares") of Needham Aggressive Growth Fund (the "Fund"), a series of the Company.

As counsel to the Fund and in connection with this opinion, we have examined such documents and reviewed such questions of law as we deem appropriate. We are familiar with the action taken by the Board of Directors of the Company to authorize the issuance of the Shares and to register or qualify the sale of the Shares under any applicable state and federal laws regulating offerings and sales of securities. We have assumed that each of the Shares will be sold for the consideration described in the Registration Statement and that such consideration will be at least equal to the net asset value per share of such Shares.

On the basis of such examination, review and assumption, it is our opinion that the Shares have been duly authorized and, when issued, sold and paid for in the manner contemplated by the Registration Statement, will be legally issued, fully paid and non-assessable.

We consent to the use of this opinion as an exhibit to the Registration Statement and the reference to this firm in the Prospectus filed as part of the Registration Statement. This consent is not to be construed as an admission that we are a person whose consent is required to be filed with the Registration Statement under the provisions of the Securities Act of 1933.

Very truly yours,

/s/ Fulbright & Jaworski L.L.P.

AMENDED AND RESTATED
PLAN OF DISTRIBUTION PURSUANT TO RULE 12b-1

WHEREAS, The Needham Funds, Inc. (the "Company") is an open-end management investment company and is registered as such under the Investment Company Act of 1940, as amended (the "Act");

WHEREAS, the Company may create one or more series of shares, each of which may hold a portfolio of securities;

WHEREAS, the Company has created each of the series set forth on Exhibit A attached hereto (each a "Fund" and collectively, the "Funds"), as such Exhibit A may be amended from time to time, and the Company desires to amend and restate this Plan of Distribution (the "Plan") with respect to Needham Growth Fund and to adopt the Plan with respect to Needham Aggressive Growth Fund pursuant to Rule 12b-1 under the Act and the Directors of the Company have determined that there is a reasonable likelihood that the adoption of this Plan will benefit the Funds and their respective shareholders;

WHEREAS, the Company desires to enter into agreements with distributors and other entities (each a "Distributor" or "Service Provider") to obtain distribution services and/or shareholder services for the Funds, it being understood that the Funds may also pay for any such services outside the Plan to the extent such services may be paid for outside a Rule 12b-1 plan; and

NOW, THEREFORE, the Company, on behalf of each of the Funds, hereby adopts this Plan in accordance with Rule 12b-1 under the Act on the following terms and conditions:

1. Each Fund may pay to any Distributor or Service Provider compensation for services with respect to shares held or purchased by their respective customers or in connection with the purchase of shares attributable to the efforts of such Distributor or Service Provider, as the case may be. The amount of such compensation shall not exceed an annual rate of .25 of 1% of the aggregate average daily net assets of each Fund and shall be paid at such intervals as the Directors may determine.

2. The amount set forth in Section 1 may be paid as a service fee to any Distributor or Service Provider so long as the records of such Fund adequately detail that such amount was paid for personal service and/or the maintenance of shareholder accounts, which terms include, but are not limited to: compensation for sales; marketing activities; incentive compensation to Distributors or Service Providers to


obtain distribution services and/or shareholder services; preparation by such Fund or others of advertising or sales literature and other promotional activities; servicing shareholder accounts by processing new account applications and performing other shareholder liaison functions; preparing and transmitting records of transactions by customers to such Fund's transfer agent; serving as a source of information to such Fund's shareholders; and preparing, printing and distributing prospectuses to those persons not already shareholders of such Fund. Aggregate payments made under the Plan may exceed distribution and shareholder services expenses actually incurred.

3. With respect to each Fund, the Plan shall not take effect until the Plan, together with any related agreement, has been approved by votes of a majority of both (a) the Directors of the Company and (b) those Directors of the Company who are not "interested persons" of the Company (as defined in the Act) and have no direct or indirect interest in the operation of the Plan or any agreements related to it (the "Rule 12b-1 Directors") cast in person at a meeting (or meetings) called for the purpose of voting on the Plan and such related agreements.

4. With respect to each Fund, this Plan shall remain in effect for a period of one year after its approval and shall continue in effect thereafter so long as such continuance is specifically approved at least annually in the manner provided for approval of this Plan in Section 3.

5. All persons authorized to direct the disposition of monies paid or payable by a Fund pursuant to this Plan or any related agreement shall provide to the Company's Board of Directors, and the Directors shall review, at least quarterly, a written report of the amounts so expended and the purposes for which such expenditures were made.

6. The Plan may be terminated with respect to any Fund at any time by a vote of a majority of the Rule 12b-1 Directors or by a vote of a majority of the outstanding voting securities of that Fund.

7. With respect to each Fund, this Plan may not be amended to increase materially the amount of distribution expenses payable pursuant to Section 1 hereof unless such amendment is approved by a vote of at least a majority (as defined in the Act) of the outstanding voting securities of that Fund, and no material amendment to the Plan shall be made unless approved in the manner provided in Section 3 hereof.

8. While this Plan is in effect, the selection and nomination of Directors who are not interested persons (as defined in the Act) of the Company shall be committed to the discretion of the Directors who are not such interested persons.

9. Each Fund shall preserve copies of this Plan, any related agreements and all reports made pursuant to Section 5 hereof for a period of not less than six years

-2-

from the date of the Plan, any such agreement or any such report, the first two years in an easily accessible place.

IN WITNESS WHEREOF, the Company has executed this Amended and Restated Plan of Distribution as of the day and year written below.
