January [___], 2009

Dear Shareholder:

The Trustees of the B.B. Micro-Cap Growth Fund (formerly, the Bjurman, Barry
Micro-Cap Growth Fund) (the "B.B. Fund"), a series of The B.B. Funds (the "B.B.
Trust"), have determined that it is in the best interests of the B.B. Fund and
its shareholders to reorganize the B.B. Fund into the GAMCO Westwood Mighty
Mites(SM) Fund (the "Mighty Mites Fund"), a series of the GAMCO Westwood Funds.
Shareholders of the B.B. Fund are being asked to approve the proposed
reorganization of the B.B. Fund into the Mighty Mites Fund (the
"Reorganization") at a special meeting of shareholders to be held on March 16,
2009, at 10:00 a.m. (Eastern Standard Time).

Enclosed you will find various materials, including a Combined Proxy
Statement/Prospectus and proxy ballot(s), for this special meeting. The
materials provide you with detailed information about the Reorganization,
including the reasons why the Board of Trustees of the B.B. Trust believes that
the Reorganization is in the best interests of the B.B. Fund and its
shareholders. The Board of Trustees of the B.B. Trust urges you to vote in favor
of this Reorganization.

If the Reorganization is approved by shareholders at the special meeting, at the
closing of the transaction you will receive full and fractional Class AAA Shares
of the Mighty Mites Fund equal in value at the time of the exchange to the value
of your shares of the B.B. Fund.

We believe that this combination will provide significant benefits to
shareholders of the B.B. Fund. The Reorganization will enable shareholders to
invest in a fund with substantially similar investment strategies. Combining the
two funds' assets will result in the creation of a single fund with a larger
asset base than the assets of the B.B. Fund alone. This greater asset size would
allow shareholders to take advantage of the possible benefits of economies of
scale and of spreading fixed costs across a larger asset base. Further, the
Reorganization would be tax-free and would not dilute your investment.

We urge you to vote as soon as possible. Your vote is important, regardless of
the number of shares you own. You can vote easily and quickly by mail, by phone
or in person. A self-addressed, postage-paid envelope has been enclosed for your
convenience.

EVERY VOTE COUNTS! Please cast yours as early as possible, so that Teton
Advisors, Inc., the investment adviser of the B.B. Fund, can avoid incurring
additional costs in re-soliciting your vote. Teton Advisors, Inc. will bear the
costs of the Special Meeting, including legal costs and the cost of the
solicitation of proxies. If you have questions, you may contact us, toll free,
at 1-800-GABELLI (422-3554). If you invest through another financial
institution, such as a brokerage firm, please contact your financial institution
should you have any questions.

Thank you for your continued investment in the B.B. Fund and for your support in
this matter.

Sincerely,

/s/ BRUCE N. ALPERT

COMBINED PROXY STATEMENT/PROSPECTUS

RELATING TO THE ACQUISITION OF ASSETS OF THE

B.B. MICRO-CAP GROWTH FUND
(formerly, the Bjurman, Barry Micro-Cap Growth Fund)

BY AND IN EXCHANGE FOR CLASS AAA SHARES OF THE

GAMCO WESTWOOD MIGHTY MITES(SM) FUND
a series of the GAMCO WESTWOOD FUNDS

One Corporate Center
Rye, New York 10580-1422
1-800-GABELLI (422-3554)

This Combined Proxy Statement/Prospectus relates to the proposed transfer
to the GAMCO Westwood Mighty Mites(SM) Fund (the "Mighty Mites Fund"), a series
of the GAMCO Westwood Funds, of all of the assets and known and disclosed
liabilities of the B.B. Micro-Cap Growth Fund (formerly, The Bjurman, Barry
Micro-Cap Growth Fund) (the "B.B. Fund"), a series of The B.B. Funds (formerly,
the Bjurman, Barry Funds) (the "B.B. Trust"), in exchange for Class AAA Shares
of the Mighty Mites Fund, to be distributed to the shareholders of the B.B. Fund
in liquidation and dissolution of the B.B. Fund, and the termination of the B.B.
Fund's registration statement under the Investment Company Act of 1940, as
amended (the "Reorganization"). As a result of the Reorganization, each
shareholder of the B.B. Fund would receive full and fractional Class AAA Shares
of the Mighty Mites Fund equal in value at the time of the exchange to the value
of such shareholder's shares of the B.B. Fund (each of the B.B. Fund and the
Mighty Mites Fund is referred to below as a "Fund," and collectively as the
"Funds").

The Boards of Trustees of the Funds both believe that the Reorganization is
in the best interests of the Funds and that the interests of the Funds'
shareholders will not be diluted as a result of the Reorganization. If the
Reorganization is approved, the effective expense ratio of your shares in the
Mighty Mites Fund immediately after the closing of the transaction is expected
to be lower than the effective current expense ratio of your shares in the B.B.
Fund, as described in more detail below.

For federal income tax purposes, the Reorganization is to be structured as
a tax-free transaction for the Funds and their shareholders. The investment
objectives of the Funds are substantially similar. The Mighty Mites Fund seeks
to provide long-term capital appreciation by investing primarily in
micro-capitalization equity securities (which it defines as securities of

COMBINED PROXY STATEMENT/PROSPECTUS

companies with market capitalization of $300 million or less at the time of the
Mighty Mites Fund's initial purchase). The B.B. Fund seeks capital appreciation
through investments in the common stocks of companies with market
capitalizations generally between $30 million and $300 million at the time of
investment.

This Combined Proxy Statement/Prospectus sets forth concisely information
about the Mighty Mites Fund that shareholders of the B.B. Fund should know
before investing and should be read and retained by investors for future
reference. Copies of the prospectus for the Mighty Mites Fund, dated January 21,
2009, and the annual report for the Mighty Mites Fund for the fiscal year ended
September 30, 2008, have been filed with the Securities and Exchange Commission
(the "SEC"), are enclosed herewith, and are incorporated by reference herein.

COMBINED PROXY STATEMENT/PROSPECTUS

I. PROPOSAL - TO APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION

A. OVERVIEW

At a meeting held on November 11, 2008, the Board of Trustees of the B.B.
Trust (the "B.B. Board"), including all of the Trustees who are not "interested
persons" of the B.B. Trust (the "Independent Trustees"), as that term is defined
in Section 2(a)(19) of the Investment Company Act of 1940, as amended (the "1940
Act"), considered and approved an Agreement and Plan of Reorganization and
Liquidation dated November 28, 2008 (the "Plan of Reorganization"), a copy of
which is attached to this proxy statement as Appendix A. Under the Plan of
Reorganization, the B.B. Fund will assign all of its assets and known and
disclosed liabilities to the Mighty Mites Fund in exchange for a number of Class
AAA Shares of the Mighty Mites Fund equivalent in value to shares of the B.B.
Fund outstanding immediately prior to the Closing Date (as defined below). This
will be followed by a distribution of those shares to B.B. Fund shareholders so
that each B.B. Fund shareholder would receive shares of the Mighty Mites Fund
equivalent to the value of B.B. Fund shares held by such shareholder on the date
of the transaction (the "Closing Date"), currently scheduled on or about March
27, 2009, the subsequent liquidation and dissolution of the B.B. Fund, and the
termination of the B.B. Trust's registration statement under the 1940 Act (this
proposed transaction is referred to as the "Reorganization"). Like the B.B.
Fund, the Mighty Mites Fund is a series of an open-end investment company
registered with the SEC.

If the Reorganization is approved and implemented, shareholders of the B.B.
Fund will become shareholders of the Mighty Mites Fund. The B.B. Fund and the
Mighty Mites Fund have the same investment adviser, Teton Advisors, Inc.
("Teton" or the "Adviser"). The Mighty Mites Fund's investment objective is
substantially similar to the B.B. Fund's investment objective and the Mighty
Mites Fund's principal investment strategies are substantially similar to those
of the B.B. Fund, as discussed in further detail below.

The B.B. Board recommends that the shareholders of the B.B. Fund vote "FOR"
the Plan of Reorganization and the resulting Reorganization.

B. COMPARISON FEE TABLE AND EXAMPLES

The following table shows the comparative fees and expenses of the Funds as
of September 30, 2008. The table also reflects the pro forma fees for the Mighty
Mites Fund after giving effect to the Reorganization, also as of September 30,
2008.

TOTAL ANNUAL FUND OPERATING EXPENSES 1.69%(5) 1.76% 1.50%

(1) In order to discourage frequent short-term trading in its shares, the B.B.
Fund imposes a 2.00% redemption fee on shares that are redeemed or
exchanged within 60 days of purchase.

(2) As of December 15, 2008, the B.B. Fund is the only series of the B.B. Trust
and therefore, the exchange fee is not applicable as the B.B. Fund's
exchange privilege extended only to other series in the B.B. Trust.

(3) In order to discourage frequent short-term trading in its shares, the
Mighty Mites Fund imposes a 2.00% redemption fee (short-term trading fee)
on Class AAA Shares that are redeemed or exchanged within seven days or
less after the date of purchase.

(4) Acquired Fund Fees and Expenses ("AFFE") represent the pro rata expenses
indirectly incurred by the Mighty Mites Fund as a result of investing in
other mutual funds that have their own expenses. AFFE are not used to
calculate the Mighty Mites Fund's net asset value and therefore the ratios
in the table above do not correlate to the Ratios to Average Net Assets and
Supplemental Data found in the "Financial Highlights" section of the Mighty
Mites Fund prospectus or to the Financial Highlights section herein.

(5) The B.B. Fund's previous investment adviser, Bjurman, Barry & Associates
("BB&A"), historically waived, on a voluntary basis, all or a portion of
its fee and reimbursed certain expenses of the B.B. Fund necessary to limit
total operating expenses to 1.80% of the B.B. Fund's average net assets.
BB&A reserved the right to terminate or modify the waiver or any
reimbursements at any time in its sole discretion. BB&A informed the B.B.
Board in May 2008 that it would no longer waive its fees in respect of, or
reimburse the B.B. Fund for, certain fees and expenses, including those
related to the Independent Trustees' independent exploration and evaluation
of strategic alternatives regarding the future of the B.B. Fund. In
addition, BB&A terminated all waivers and reimbursements on October 22,
2008. Teton, the B.B. Fund's current investment adviser (since November 28,
2008), has agreed to reduce or waive all or a portion of its investment
advisory fees, and to reimburse expenses of the B.B. Fund, in order to
limit certain operating expenses of the B.B. Fund to 1.80% of the average
annual net assets, excluding extraordinary expenses, for the duration of
the B.B. Fund's interim advisory agreement with Teton.

COMBINED PROXY STATEMENT/PROSPECTUS

EXAMPLE

The Example below is intended to help you compare the cost of investing in
the B.B. Fund with the cost of investing in the Mighty Mites Fund. The Example
assumes that you invest $10,000 in the specified Fund for the time periods
indicated and then redeem all of your shares at the end of those periods. The
Example also assumes that your investment has a 5% return each year, dividends
and distributions are reinvested, and the operating expenses remain the same.
Although your actual costs may be higher or lower, under the assumptions, your
costs would be:

investment objective by using the principal investment strategies discussed
below. The Funds' principal strategies are substantially similar, except as
noted below. The main difference in the Funds' principal investment strategies
is that the B.B. Fund has a policy of investing at least 80% of its total assets
in stocks of micro-cap companies and the Mighty Mites Fund has a policy to
invest "primarily" in micro-cap companies. Furthermore, the Mighty Mites Fund
may invest up to 25% in foreign stocks, whereas the B.B. Fund does not invest in
foreign investments as a principal investment strategy. The combined fund will

PRINCIPAL INVESTMENT RISKS

Because of their similar investment objectives and strategies, the B.B.
Fund and the Mighty Mites Fund have substantially similar risks. A discussion of
the principal risks of investing in the Funds is set forth below. This
discussion is qualified in its entirety by the more extensive discussion of risk
factors set forth in the prospectuses and statements of additional information
of the Funds. The combined fund will have the same risks as the Mighty Mites
Fund.

FUND AND MANAGEMENT RISK. If the Adviser's judgment in selecting securities
is incorrect or if the market segment in which the Funds invest falls out of
favor with investors, the Funds could underperform the stock market or their
peers. The Funds could also fail to meet their investment objective. When you
sell the Funds' shares, they may be worth less than what you paid for them.
Therefore, you may lose money by investing in the Funds.

EQUITY RISK. The principal risk of investing in the Funds is equity risk.
Equity risk is the risk that the prices of the securities held by the Funds will
fall due to general market and economic conditions, perceptions regarding the
industries in which the companies issuing the securities participate, and the
issuer company's particular circumstances.

SMALL- AND MICRO-CAP RISK. Although small-cap and micro-cap companies may
offer greater potential for capital appreciation than larger companies,
investing in securities of small-cap and micro-cap companies may involve greater
risks than investing in larger, more established issuers. Small-cap and
micro-cap companies generally have limited product lines, markets, and financial
resources. Their securities may trade less frequently and in more limited volume
than the securities of larger, more established companies. Also, small-cap and
micro-cap companies are typically subject to greater changes in earnings and
business prospects than larger companies. Consequently, small-cap and micro-cap
company stock prices tend to rise and fall in value more than other stocks. The
risks of investing in micro-cap stocks and companies are even greater than those
of investing in small-cap companies.

In addition, while both Funds may invest in foreign securities, the Mighty
Mites Fund has disclosed the following risk in its prospectus:

FOREIGN SECURITIES RISK. The Mighty Mites Fund may invest up to 25% of its
total assets in foreign equity securities and in European Depository Receipts or
American Depository Receipts. The Mighty Mites Fund may also invest in foreign
debt securities. Foreign securities pose additional risks over U.S. based
securities for a number of reasons. Foreign economic, governmental, and
political systems may be less favorable than those of the U.S. Foreign
governments may exercise greater control over their

COMBINED PROXY STATEMENT/PROSPECTUS

economies, industries, and citizens' rights. Specific risk factors related to
foreign securities include: inflation, structure and regulation of financial
markets, liquidity and volatility of investments, currency exchange rates and
regulations, and differing accounting standards. Foreign companies may also be
subject to significantly higher levels of taxation than U.S. companies,
including potentially confiscatory levels of taxation, thereby reducing their
earnings potential, and amounts realized on foreign securities may be subject to
high levels of foreign taxation.

Foreign securities may be denominated in foreign currencies. Therefore, the
value of the Mighty Mites Fund's assets and income in U.S. dollars may be
affected by changes in exchange rates and regulations, since exchange rates for
foreign currencies change daily. The combination of currency risk and market
risk tends to make securities traded in foreign markets more volatile than
securities traded exclusively in the U.S. Although the Mighty Mites Fund values
its assets daily in U.S. dollars, it will not convert its holdings of foreign
currencies to U.S. dollars daily. Therefore, the Mighty Mites Fund may be
exposed to currency risks over an extended period of time.

In addition, the B.B. Fund has disclosed the following risks in its
prospectus:

IPO RISK. The B.B. Fund may invest in initial public offerings, or IPOs.
The risks associated with IPOs include short earnings histories, competitive
conditions and reliance on a limited number of product lines and financial
resources. There is also no guarantee that the B.B. Fund will continue to have
access to the types of IPOs that have previously contributed to its performance
or that any IPO will perform as well as previous IPOs.

DIVERSIFICATION RISK. Diversifying a mutual fund's portfolio can reduce the
inherent risks of investing by limiting the portion of your investment in any
one issuer or industry. Less diversified mutual funds may be more sensitive to
changes in the market value of a single issuer or industry. The B.B. Fund may
present greater risk than is usually associated with more widely diversified
mutual funds because the B.B. Fund may invest in as few as 50 issuers.

The Mighty Mites Fund is not subject to IPO risk to the same extent as the
B.B. Fund might be since the Mighty Mites Fund does not invest in IPOs as a
principal investment strategy. The Mighty Mites Fund is also not subject to
diversification risk as the Mighty Mites Fund's portfolio is generally more
widely diversified than that of the B.B. Fund.

DISCLOSURE OF PORTFOLIO HOLDINGS

The portfolio holdings policy for the Mighty Mites Fund is identical to
that of the B.B. Fund. A description of the Funds' policies and procedures with
respect to the disclosure of the portfolio securities is available in the
Statement of Additional Information for each of the Funds.

INVESTMENT RESTRICTIONS AND LIMITATIONS

A chart comparing all of the fundamental and non-fundamental investment
restrictions of the Mighty Mites Fund with those of the B.B. Fund is attached as
Appendix B. The main difference between

COMBINED PROXY STATEMENT/PROSPECTUS

the investment restrictions of the B.B. Fund and the Mighty Mites Fund is that
the B.B. Fund has a 15% industry concentration policy, whereas the Mighty Mites
Fund has a 25% industry concentration policy. In addition, the B.B. Fund has a
stricter portfolio diversification policy than the Mighty Mites Fund. The
combined fund will follow the investment restrictions and limitations of the
Mighty Mites Fund.

LEGAL PROCEEDINGS

On April 24, 2008, Gabelli Funds, LLC ("Gabelli Funds"), an affiliate of
Teton, entered into an administrative settlement with the SEC to resolve the
SEC's inquiry regarding prior frequent trading activity in shares of the GAMCO
Global Growth Fund (the "Global Growth Fund") by one investor who was banned
from the Global Growth Fund in August 2002. In the settlement, the SEC found
that the Gabelli Funds had violated Section 206(2) of the Investment Advisers
Act, Section 17(d) of the 1940 Act and Rule 17d-1 thereunder, and had aided and
abetted and caused violations of Section 12(d)(1)(B)(i) of the 1940 Act. Under
the terms of the settlement, Gabelli Funds, while neither admitting nor denying
the SEC's findings and allegations, agreed, among other things, to pay the
previously reserved total of $16 million (including a $5 million penalty), of
which at least $11 million will be distributed to shareholders of the Global
Growth Fund in accordance with a plan to be developed by an independent
distribution consultant, and approved by the independent directors of the Global
Growth Fund and the staff of the SEC, and to cease and desist from future
violations of the above-referenced federal securities laws. The settlement will
not have a material adverse impact on Gabelli Funds or its ability to fulfill
its obligations under the investment advisory agreement. On the same day, the
SEC filed a civil action against the Executive Vice President and Chief
Operating Officer of Gabelli Funds, alleging violations of certain federal
securities laws arising from the same matter. The officer is also an officer of
the Global Growth Fund and other funds in the Gabelli/GAMCO fund complex,
including the Funds. The officer denies the allegations and is continuing in his
positions with Gabelli Funds and other funds in the Gabelli/GAMCO fund complex,
including the Funds. Teton currently expects that any resolution of the action
against the officer will not have a material adverse impact on Teton or its
ability to fulfill its obligations under the investment advisory agreements with
the Funds.

E. KEY INFORMATION ABOUT THE PROPOSAL

The following is a summary of key information concerning the proposed
Reorganization. Keep in mind that more detailed information appears in the Plan
of Reorganization, which is attached to this Proxy Statement/Prospectus in
APPENDIX A.

1. SUMMARY OF THE PROPOSED REORGANIZATION

On November 11, 2008, the Board of the B.B. Trust, on behalf of the B.B.
Fund, approved the Plan of Reorganization, which contemplates the transfer to
the Mighty Mites Fund of all of the assets and known and disclosed liabilities
of the B.B. Fund solely in exchange for Class AAA Shares of beneficial interest
of the Mighty Mites Fund. Following the transfer, Class AAA Shares of the Mighty
Mites Fund will be distributed to shareholders of the B.B. Fund in liquidation
of the B.B. Fund and the B.B. Fund will subsequently be dissolved. In connection
therewith, the B.B. Trust will terminate its registration under the 1940 Act by
filing the appropriate application with the SEC.

Both Funds are equity funds with substantially similar investment
objectives and strategies. Both Funds are managed by Teton. The Funds' Boards
and the Adviser recognize that greater economies of

COMBINED PROXY STATEMENT/PROSPECTUS

scale and efficiencies can be attained by combining the assets of the Funds and
that since the investment objectives are substantially identical, such a
combination would not materially alter the nature of the B.B. Fund's
shareholders' investment.

As a result of the Reorganization, each shareholder of the B.B. Fund will
receive full and fractional shares of Class AAA Shares of the Mighty Mites Fund
equal in value at the time of the Reorganization to the value of such
shareholder's shares of the B.B. Fund. The B.B. Trust's Board has determined
that the interests of existing shareholders will not be diluted as a result of
the transactions contemplated by the Reorganization. For the reasons set forth
below under "Reasons for the Reorganization," the B.B. Trust's Board, on behalf
of the B.B. Fund, including the Independent Trustees, concluded that the
Reorganization would be in the best interest of the shareholders of the B.B.
Fund and recommends approval of the Plan of Reorganization.

2. DESCRIPTION OF THE MIGHTY MITES FUND'S CLASS AAA SHARES

The Mighty Mites Fund's Class AAA Shares to be issued to the B.B. Fund's
shareholders pursuant to the Reorganization will be duly authorized, validly
issued, fully paid and nonassessable when issued, and will be transferable
without restriction and will have no preemptive or conversion rights. The Mighty
Mites Fund's Class AAA Shares will be sold and redeemed based upon the net asset
value ("NAV") per share of the Mighty Mites Fund Class AAA Shares next
determined after receipt of the purchase or redemption request, as described in
the Mighty Mites Fund's Prospectus.

3. REASONS FOR THE REORGANIZATION

The recommendation of the B.B. Board with respect to the Reorganization of
the B.B. Fund arose from discussions of strategic alternatives for the B.B.
Trust, of which the B.B. Fund is a separate series) over a period of several
years, as described below. As a result of those discussions, the B.B. Board and
BB&A mutually agreed that the previous investment advisory agreement between the
B.B. Trust and BB&A with respect to the B.B. Fund should not be renewed after
the expiration of the term of the agreement on November 28, 2008, and the
Independent Trustees selected Teton as the interim investment adviser to the
B.B. Fund pending shareholder approval of the Reorganization. The B.B. Board
also approved the liquidation of the other two series of the B.B. Trust, the
Bjurman, Barry Mid Cap Growth Fund (the "Mid Cap Fund") and the Bjurman, Barry
Small Cap Growth Fund (the "Small Cap Fund"), which were liquidated on December
15, 2008.

BOARD DISCUSSIONS FROM JUNE 2006 - MARCH 2008

As a result of discussions at meetings of the B.B. Board and its
Committees, in June 2006 the Independent Trustees developed and provided to BB&A
a list of strategic issues of concern related to the future operations of the
B.B. Trust. These concerns included matters such as the impact of increasing
shareholder redemptions from the B.B. Fund on its investment results (the assets
of the B.B. Fund had declined from approximately $822 million in March 2004 to
approximately $505 million in June 2006); BB&A's short-range and long-range
plans for marketing and distribution of the B.B. Fund, the Mid Cap Fund and the
Small Cap Fund; and the long-term viability of the Mid Cap Fund and the Small
Cap Fund (which had assets of only $7.6 million and $26 million respectively as
of June 2006).

The B.B. Board recognized that many of these issues would be resolved by
improved investment performance and that the market environment had not been
favorable for BB&A's growth-oriented

COMBINED PROXY STATEMENT/PROSPECTUS

investment approach. Accordingly, the B.B. Board continued to discuss these
matters at subsequent meetings of the B.B. Board and its Committees.

BB&A'S MARCH 2008 REORGANIZATION PROPOSAL

At a special meeting of the B.B. Board on March 27, 2008, BB&A informed the
Independent Trustees that, in response to the Independent Trustees' concerns,
BB&A had concluded that the B.B. Trust and BB&A would benefit if BB&A were able
to identify a suitable strategic partner that would provide the B.B. Trust
greater economic and administrative strength than that of BB&A alone, while
continuing BB&A's management of the B.B. Trust. BB&A informed the Independent
Trustees that it had undertaken efforts beginning in August 2006 to identify
such a partner, and had tentatively agreed on the terms of a transaction with an
experienced investment management firm that was currently managing assets in
excess of $4 billion, including assets of three mutual fund portfolios (the
"Proposed Manager"). The proposed transaction, which was subject to approval by
the Independent Trustees and the shareholders of the B.B. Trust, contemplated
the appointment of the Proposed Manager as the investment adviser to the B.B.
Trust in place of BB&A, and the appointment of BB&A as a sub-adviser to carry
out day-to-day portfolio management of the B.B. Trust, without change in the
aggregate advisory fees paid by the B.B. Trust.

The Independent Trustees carefully considered the proposed transaction.
They received a presentation by executives of the Proposed Manager and by BB&A;
with respect to the proposed transaction at the March Board meeting; discussed
the potential advantages of the proposed transaction with BB&A requested
additional information about the Proposed Manager and the process that had
resulted in selection of the Proposed Manager; and appointed a Special Committee
of two Independent Trustees who visited with executives of the Proposed Manager
and directors of its mutual funds at its principal offices. The Special
Committee also held informal discussions with a number of consulting firms about
other possible alternatives for the B.B. Trust and the costs of obtaining
professional consulting assistance to explore those alternatives.

After consideration of the proposed transaction, the process which had
resulted in identification of the Proposed Manager, and possible alternatives,
the Independent Trustees informed BB&A at a meeting of the B.B. Board on May 14,
2008, that they were not in a position to approve the proposed transaction with
the Proposed Manager because they believed that it did not appear to provide
significant tangible benefits to the B.B. Trust's shareholders and because the
Independent Trustees did not have a fully informed view about other possible
alternatives.

INDEPENDENT TRUSTEE REVIEW OF ALTERNATIVE TRANSACTIONS

Thereafter, the Independent Trustees met on numerous occasions, with the
assistance of counsel to the B.B. Trust and the Independent Trustees, to discuss
and evaluate strategic alternatives for the B.B. Trust:

- The members of the Special Committee met with management of BB&A in
June 2008 to discuss a variety of matters regarding operation of the
B.B. Trust, including among other things the reasons for the
Independent Trustees' conclusions about the proposed transaction and
various possible methods of improving the benefits of the transaction
to the B.B. Trust's shareholders. At the Independent Trustees'
request, representatives of BB&A discussed with the Proposed Manager
ways of providing additional benefits to the B.B. Trust's
shareholders. However, the Proposed Manager declined to propose any
such additional benefits.

COMBINED PROXY STATEMENT/PROSPECTUS

- At a special meeting of the B.B. Board on July 23, 2008, the B.B.
Board considered a written report on the costs and benefits of
alternative strategic transactions for the B.B. Trust prepared by BB&A
at the request of the Independent Trustees. These alternatives
included reorganization of the B.B. Trust with a fund group managed by
a third party adviser, reorganization pursuant to an arrangement for
continuation of BB&A's services to the B.B. Trust as a sub-adviser,
merger of the Small Cap and Mid Cap Funds, liquidation of the B.B.
Trust, and maintenance of the status quo. At that meeting, BB&A
informed the Independent Trustees that, in view of the small size of
the B.B. Trust and continuing redemptions by shareholders of the B.B.
Fund (the assets of which had declined to approximately $145 million),
BB&A did not believe that the B.B. Trust would be able to compete
effectively in the mutual fund marketplace in the future, and that
maintenance of the status quo was not a viable option. The Independent
Trustees (i) requested that BB&A contact a number of "multiple series
trusts" sponsored by mutual fund administrators to determine whether
reorganization of one or more series of the B.B. Trust into newly
organized series of such a trust, managed by BB&A, would result in
significant expense savings to the shareholders of the B.B. Trust, and
(ii) authorized retention of an experienced consulting firm identified
by the Special Committee, to contact a select list of potential mutual
fund managers that might be interested in a transaction with respect
to the B.B. Trust (whether or not BB&A would continue to manage the
B.B. Trust).

- At a meeting of the B.B. Board on August 12, 2008, the B.B. Board
considered management's report on its contacts with various "multiple
series trust" sponsors. The Independent Trustees concluded that
although reorganization of the B.B. Trust into such a trust might
provide some expense reductions, it would not resolve issues related
to distribution of the B.B. Trust.

- During August and September 2008, under the supervision of the
Independent Trustees, the Special Committee and its consultant
identified 31 potential fund companies not previously contacted by
BB&A, and made inquiries of 19 of those companies identified as having
possible interest in a transaction with respect to the B.B. Trust. The
Special Committee received letters of interest from eight of those
companies. During this period the Independent Trustees held four
meetings with their consultant and with counsel to review and evaluate
the letters of interest.

- At a special meeting of the B.B. Board on October 1, 2008, the
Independent Trustees recommended that management of BB&A contact three
of the fund managers who had expressed interest to obtain additional
information from them. At a special meeting of the B.B. Board on
October 8, 2008, management of BB&A reported that it had briefly
contacted each of the three fund managers identified by the
Independent Trustees and, although a transaction with any of the
managers offered compensation to BB&A, BB&A did not believe it was in
the best interest of the B.B. Trust or its shareholders to pursue
further discussions with any of them. BB&A also indicated that it had
concluded it did not wish to continue to manage the B.B. Trust after
the expiration of the current term of its advisory agreements on
November 28, 2008.

COMBINED PROXY STATEMENT/PROSPECTUS

- After further discussion with the Special Committee and its
consultant, the Independent Trustees selected GAMCO Investors, Inc.
("GAMCO"), the parent company of Teton, and one other substantial
investment adviser, both of which currently managed successful
micro-cap mutual funds, for final evaluation. The Special Committee
requested further information from the two finalists and on October
21, 2008, all of the Independent Trustees and counsel met with
representatives of each finalist in person to discuss their investment
philosophies, management capabilities, and other relevant matters.

- As a result of those meetings, the Independent Trustees unanimously
determined that it would be in the best interest of the B.B. Trust to
liquidate the Small Cap Fund and the Mid Cap Fund and to retain Teton,
a subsidiary of GAMCO, as investment adviser to the B.B. Fund at the
end of the current term of the B.B. Fund's agreement with BB&A. Teton
thereafter concluded that it could best manage the assets of the B.B.
Fund if the B.B. Fund were reorganized into the Mighty Mites Fund. In
evaluating this conclusion, the Independent Trustees met on October
29, 2008, to consider such a reorganization and to review responses to
information requested on their behalf by counsel with respect to the
Mighty Mites Fund, and also conducted a telephonic interview with the
lead independent director of the Mighty Mites Fund.

BOARD CONSIDERATIONS WITH RESPECT TO THE REORGANIZATION

At a meeting of the B.B. Board on October 31, 2008, the B.B. Board approved
(i) by unanimous vote, the liquidation of the Mid Cap and Small Cap Funds, and
(ii) by unanimous vote of the four members then serving as Independent Trustees,
and with the two members of the B.B. Board who were affiliated with BB&A
abstaining as they had not participated in the selection process, a letter of
intent with GAMCO for the appointment of Teton to act as interim investment
adviser to the B.B. Fund commencing on November 28, 2008, for a period of up to
150 days, as permitted by SEC rules, and for the proposed Reorganization of the
B.B. Fund into the Mighty Mites Fund by the end of that period, subject to
approval of the shareholders of the B.B. Fund. Thereafter, at a meeting of the
B.B. Board on November 12, 2008, the B.B. Board (with the two members affiliated
with BB&A abstaining) approved an interim investment advisory agreement with
Teton and the Plan of Reorganization with the Mighty Mites Fund.

The Independent Trustees considered a number of factors in determining that
the proposed Reorganization would be in the best interest of the B.B. Fund and
its shareholders, and that the interests of the B.B. Fund's existing
shareholders would not be diluted as a result of the proposed Reorganization,
including the following:

1. The Independent Trustees and BB&A mutually agreed that the previous
investment advisory agreement between the B.B. Fund and BB&A should not be
renewed after the expiration of the term of the agreement on November 28,
2008.

2. Based on their review of the alternatives available to the B.B.
Fund and information provided by GAMCO with respect to Teton and the Mighty
Mites Fund, the Independent Trustees unanimously determined that it would
be in the best interests of the B.B. Fund and its shareholders to obtain
the services of Teton as investment adviser to the B.B. Fund while it
solicits shareholder

COMBINED PROXY STATEMENT/PROSPECTUS

approval with respect to the proposed Reorganization. In making this
determination, the Independent Trustees considered a variety of factors,
including the following:

INVESTMENT OBJECTIVES AND STRATEGIES. As described above, the
Independent Trustees considered that the investment objectives and
strategies of the Mighty Mites Fund were substantially similar to
those of the B.B. Fund, including their mutual focus on seeking
capital appreciation from investing in micro cap stocks.

NATURE, EXTENT AND QUALITY OF SERVICES. The Independent Trustees
considered the depth and quality of Teton's investment management
process, including its extensive research capabilities; the experience
of Teton's senior management and other personnel; the overall
financial strength, size, stability and reputation of GAMCO; the
nature, extent and quality of administrative, compliance and
shareholder services available to the Mighty Mites Fund from Teton and
its affiliates; and the benefits to B.B. Fund shareholders from
investing in a fund that is part of a larger family of funds. The
Independent Trustees concluded that the nature, extent and quality of
the services proposed to be provided by Teton and the Mighty Mites
Fund would benefit the B.B. Fund and its shareholders.

INVESTMENT RESULTS. The Independent Trustees considered the investment
results of the Mighty Mites Fund. They noted that the performance of
the Mighty Mites Fund was substantially better than that of the B.B.
Fund for the one-, three-, and five-year periods ended June 30, 2008.
They also noted that the performance of the Mighty Mites Fund was
substantially better than the results of the Russell 2000 Index for
all these periods and since inception of the Mighty Mites Fund in May
1998, better than the results of the Russell MicroCap Index for all
such periods since the inception of that Index, and well above the
average of a peer group of funds identified by Lipper Inc. for such
periods; and that the Mighty Mites Fund had a five-star Morningstar
rating. The Independent Trustees concluded that Teton's record in
managing the Mighty Mites Fund could significantly benefit the
shareholders of the B.B. Fund.

ADVISORY FEES AND TOTAL EXPENSES. The Independent Trustees compared
the advisory fee and total expense ratios of the Mighty Mites Fund to
those of the B.B. Fund and other relevant funds. The Independent
Trustees noted that Teton's advisory fee was the same as that of BB&A.
They noted that on October 22, 2008, BB&A had terminated its voluntary
agreement to waive all or a portion of its fees, and to reimburse
expenses of the B.B. Fund, in order to limit certain operating
expenses of the B.B. Fund to 1.80% of the average annual net assets,
and that the total expenses of the Mighty Mites Fund (as of the date
of their meeting) were less than those of the B.B. Fund. The
Independent Trustees also considered the pro forma expense ratio of
the combined Mighty Mites Fund after the Reorganization, noting that
the total pro forma expense ratio of the combined fund would be less
than that of the B.B. Fund. They noted that based on their review of
data in connection with past renewals of the B.B. Fund's Agreement
with BB&A, the advisory fees and projected expenses of the Mighty
Mites Fund were at or below the medians for comparable funds. The
Independent Trustees further considered that the Mighty Mites Fund's
greater

COMBINED PROXY STATEMENT/PROSPECTUS

distribution capabilities could potentially increase overall fund
assets thereby enabling B.B. Fund shareholders to benefit from certain
economies of scale after the Reorganization.

The Independent Trustees noted that Teton's advisory fee structure did
not include fee breakpoints. However, they considered that such
breakpoints were of limited value as any potential economies of scale
in the operation of the Mighty Mites Fund were limited by the likely
need to close the Mighty Mites Fund to further investment at some
point in the future given the constraints of any adviser's ability to
manage assets in the micro-cap sector of the stock market. They also
reviewed information regarding the pre-tax operating margins of Teton
with respect to its advisory services to the Mighty Mites Fund. The
Independent Trustees concluded that the Mighty Mites Fund's cost
structure was fair and reasonable in relation to the services provided
by Teton, and that the shareholders of the B.B. Fund would receive
reasonable value in return for the advisory fees paid by the Mighty
Mites Fund.

ANCILLARY BENEFITS. The Independent Trustees considered a variety of
other benefits received by Teton and its affiliates as a result of
Teton's relationship with the Mighty Mites Fund, including
compensation paid to Gabelli & Company, Inc., a broker-dealer
affiliate of Teton which acts as distributor of the Mighty Mites
Fund's shares and executes some portfolio transactions for the Mighty
Mites Fund; the benefits of "soft dollar" research and other services
obtained, if any, by Teton from broker-dealers in return for
allocating Mighty Mites Fund brokerage transactions to such
broker-dealers; and other possible ancillary benefits to Teton and its
affiliates as a result of their relationship to the Mighty Mites Fund.
The Independent Trustees took these ancillary benefits into account in
evaluating the reasonableness of the advisory fees and other amounts
paid to Teton by the Mighty Mites Fund.

OTHER FACTORS. The Independent Trustees considered the terms and
conditions of the Reorganization, including that the Reorganization
would not be a taxable transaction to the shareholders of the B.B.
Fund. They further noted that Teton has agreed to bear the expenses of
the Special Meeting (including legal, proxy and solicitation
expenses), reimburse the B.B. Fund for legal fees incurred over
several weeks (up to a maximum of $10,000) with respect to the
preparation of the letter of intent between the B.B. Trust (on behalf
of the B.B. Fund) and Teton, and bear any expenses payable by the B.B.
Fund in connection with its current accounting, administration,
transfer agency and/or custodian agreements that may be triggered by
the termination of any such agreements in connection with the proposed
Reorganization.

On December 3, 2008, the two members of the B.B. Board affiliated with
BB&A, and one of the Independent Trustees, resigned. For the reasons described
above, the current members of the B.B. Fund Board, all of whom are Independent
Trustees, unanimously recommends a vote IN FAVOR of the proposed Plan of
Reorganization and the resulting Reorganization.

4. FEDERAL INCOME TAX CONSEQUENCES

Each Fund intends to qualify, as of the Closing Date, as a "regulated
investment company" under the Internal Revenue Code of 1986, as amended (the
"Code"). Accordingly, each of the Funds have been, and expect to continue to be,
relieved of all or substantially all federal income taxes. The exchange of the

COMBINED PROXY STATEMENT/PROSPECTUS

assets of the B.B. Fund for shares of Mighty Mites Fund and the assumption by
the Mighty Mites Fund of the liabilities of the B.B. Fund, and the liquidation
of the B.B. Fund, are intended to qualify for federal income tax purposes as a
tax-free reorganization under Section 368(a)(1)(C) of the Code. As a condition
to the closing of the proposed transaction, the Funds will each receive an
opinion of Paul, Hastings, Janofsky & Walker LLP, counsel to the Funds, to the
effect that, based on certain assumptions and on the existing provisions of the
Code, Treasury Regulations issued thereunder, current Revenue Rulings, Revenue
Procedures and court decisions, for federal income tax purposes:

(1) The transfer of all of the assets and liabilities of the B.B.
Fund to the Mighty Mites Fund in exchange for shares of the
Mighty Mites Fund and the distribution to shareholders of the
B.B. Fund of shares of the Mighty Mites Fund, as described in the
Plan, will constitute a tax-free "reorganization" within the
meaning of Section 368(a)(1)(C) of the Code, and the B.B. Fund
and the Mighty Mites Fund each will be considered "a party to a
reorganization" within the meaning of Section 368(b) of the Code;

(2) No gain or loss will be recognized by the B.B. Fund upon (a) the
transfer of its assets and liabilities to the Mighty Mites Fund
in exchange for the issuance of shares of the Mighty Mites Fund
to the B.B. Fund and the assumption by the Mighty Mites Fund of
the B.B. Fund's liabilities, if any, and (b) the distribution by
the B.B. Fund to its shareholders of shares of the Mighty Mites
Fund received as a result of the Reorganization (Sections 361(a),
354(a) and 357(a) of the Code);

(3) No gain or loss will be recognized by the Mighty Mites Fund upon
its receipt of the assets and liabilities of the B.B. Fund in
exchange for the issuance of shares of the Mighty Mites Fund to
the B.B. Fund and the assumption by the Mighty Mites Fund of the
B.B. Fund's liabilities, if any (Section 1032(a) of the Code);

(4) The tax basis of the Mighty Mites Fund shares received by a
shareholder of the B.B. Fund will be the same as the tax basis of
the shareholder's B.B. Fund shares immediately prior to the
Reorganization (Section 358(a)(i) of the Code);

(5) The tax basis of the Mighty Mites Fund in the assets and
liabilities of the B.B. Fund received pursuant to the
Reorganization will be the same as the tax basis of the assets
and liabilities in the hands of the B.B. Fund immediately before
the Reorganization (Section 362(b) of the Code);

(6) The tax holding period for the shares of the Mighty Mites Fund
issued in connection with the Reorganization will be determined
by including the period for which the shareholder held shares of
the B.B. Fund exchanged therefor, provided that the shareholder
held such shares of the B.B. Fund as capital assets;

(7) The tax holding period for the Mighty Mites Fund with respect to
the assets and liabilities of the B.B. Fund received in the
Reorganization will include the period for which such assets and
liabilities were held by the B.B. Fund (Section 1223(2) of the
Code); and

COMBINED PROXY STATEMENT/PROSPECTUS

(8) the B.B. Fund's shareholders will not recognize gain or loss upon
the exchange of their shares of the B.B. Fund for shares of the
Mighty Mites Fund as part of the Reorganization.

SHAREHOLDERS OF THE B.B. FUND SHOULD CONSULT THEIR TAX ADVISERS REGARDING THE
EFFECT, IF ANY, OF THE REORGANIZATION IN LIGHT OF THEIR INDIVIDUAL
CIRCUMSTANCES, INCLUDING STATE AND LOCAL TAX CONSEQUENCES, IF ANY, OF THE
REORGANIZATION.

The opinion of Paul, Hastings, Janofsky & Walker LLP is based on the Code,
Treasury Regulations promulgated thereunder, administrative pronouncements and
judicial interpretations thereof, in each case as in effect on the date thereof,
all of which are subject to change. An opinion of counsel merely represents
counsel's best judgment with respect to the probable outcome on the merits and
is not binding on the Internal Revenue Service or the courts. Accordingly, there
can be no assurance that the Internal Revenue Service will not take a contrary
position, that the applicable law will not change, or that any such change will
not have retroactive effect.

Teton reserves the right to sell portfolio securities and/or purchase other
securities for the B.B. Fund before the Reorganization, to the extent necessary
so that the asset composition of the B.B. Fund is consistent with the investment
strategies, policies and restrictions of the Mighty Mites Fund. To the extent
the B.B. Fund sells securities at a net gain, current shareholders may receive a
capital gain distribution. It is expected that in the regular course of its
management of the B.B. Fund's portfolio, Teton will engage in such transactions
before the consummation of the Reorganization.

The B.B. Fund has no capital loss carryovers as of September 30, 2008.

5. COMPARISON OF SHAREHOLDER RIGHTS

Set forth below is a discussion of the material differences between the
B.B. Fund and the rights of its shareholders, and the Mighty Mites Fund and the
rights of its shareholders.

GOVERNING LAW. The B.B. Fund is a separate series of the B.B. Trust, which
is organized as a Delaware statutory trust. The Mighty Mites Fund is a separate
series of the GAMCO Westwood Funds, which is organized as a Massachusetts
business trust. The B.B. Fund and Mighty Mites Fund are each authorized to issue
an unlimited number of shares of beneficial interest. Each of the B.B. Trust's
and GAMCO Westwood Fund's operations are governed by their respective trust
instruments, as amended, by-laws and applicable state laws.

SHAREHOLDER LIABILITY. Under Delaware law, shareholders of a statutory
trust are generally afforded by statute the same limited liability as corporate
shareholders and are permitted liberal indemnification rights. The risk of a
shareholder of the B.B. Fund incurring financial loss on account of shareholder
liability is limited to circumstances in which both inadequate insurance exists
and the B.B. Fund itself is unable to meet its obligations. Under Massachusetts
law, shareholders of a Massachusetts business trust, under certain
circumstances, could be held personally liable for the obligations of the
business trust. However, the GAMCO Westwood Funds' Amended and Restated Trust
Agreement provides that in the case any shareholder or former shareholder is
held personally liable solely by reason of his being or having

COMBINED PROXY STATEMENT/PROSPECTUS

been a shareholder and not because of his acts or omissions or for some other
reason, the shareholder or former shareholder (or his heirs, executors,
administrators or other legal representatives or in the case of a corporation or
other entity, its corporate or other general successor) shall be entitled out of
the assets of the GAMCO Westwood Funds to be held harmless from and indemnified
against all losses and expenses arising from such liability. The Trust Agreement
also provides that the GAMCO Westwood Funds, upon request, will cause its
counsel to assume the defense against any claim which, if successful, would
result in an obligation of the GAMCO Westwood Funds to indemnify the
shareholder. Thus, the Mighty Mites Fund considers the risk of a shareholder
incurring financial loss on account of shareholder liability to be remote
because it is limited to circumstances in which a disclaimer is inoperative or
the Mighty Mites Fund itself would be unable to meet its obligations.

BOARD OF TRUSTEES. The Reorganization will result in a change in the Board
of Trustees because the trustees of the GAMCO Westwood Funds are different than
the trustees of the B.B. Trust. The Board of the B.B. Trust currently has three
independent trustees. For more information, refer to the Statement of Additional
information dated August 1, 2008, for the B.B. Trust, as supplemented November
28, 2008, which is incorporated by reference into this Combined Proxy
Statement/Prospectus. The Board of Trustees of the GAMCO Westwood Funds has four
independent trustees. For more information, refer to the Statement of Additional
Information dated January 21, 2009, for the Mighty Mites Fund, which is
incorporated by reference into this Combined Proxy Statement/Prospectus.

6. COMPARISON OF VALUATION PROCEDURES

The B.B. Fund and the Mighty Mites Fund have adopted the same pricing
procedures:

The NAV of the Funds' shares is calculated on each day the New York Stock
Exchange ("NYSE") is open. The NYSE is open Monday through Friday, but currently
is scheduled to be closed on New Year's Day, Martin Luther King, Jr. Day,
Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day,
Thanksgiving Day, and Christmas Day and on the preceding Friday or subsequent
Monday when a holiday falls on a Saturday or Sunday, respectively.

Each Fund's NAV is determined as of the close of regular trading on the
NYSE, normally 4:00 p.m., Eastern Time. NAV is computed by dividing the value of
the applicable Fund's net assets (i.e., the value of its securities and other
assets less its liabilities, including expenses payable or accrued but excluding
capital stock and surplus) attributable to its shares by the total number of
shares outstanding at the time the determination is made (with respect to the
Mighty Mites Fund, the net assets and liabilities attributable to the Class AAA
Shares). The price of Fund shares for the purpose of purchase and redemption
orders will be based upon the calculation of NAV next made after the time as of
which the purchase or redemption order is received in proper form.

COMBINED PROXY STATEMENT/PROSPECTUS

prices or, if there were no asked prices quoted on that day, then the security
is valued at the closing bid price on that day. If no bid or asked prices are
quoted on such day, the security is valued at the most recently available price
or, if the Fund's Board of Trustees so determines, by such other method as the
Board of Trustees shall determine in good faith to reflect its fair market
value. Portfolio securities traded on more than one national securities exchange
or market are valued according to the broadest and most representative market,
as determined by the Adviser.

Portfolio securities primarily traded on a foreign market are generally
valued at the preceding closing values of such securities on the relevant
market, but may be fair valued pursuant to procedures established by the Fund's
Board of Trustees if market conditions change significantly after the close of
the foreign market but prior to the close of business on the day the securities
are being valued. Debt instruments with remaining maturities of 60 days or less
that are not credit impaired are valued at amortized cost, unless the Board of
Trustees determines such amount does not reflect the securities' fair value, in
which case these securities will be fair valued as determined by the Board of
Trustees. Debt instruments having a maturity greater than 60 days for which
market quotations are readily available are valued at the average of the latest
bid and asked prices. If there were no asked prices quoted on such day, the
security is valued using the closing bid price. Futures contracts are valued at
the closing settlement price of the exchange or board of trade on which the
applicable contract is traded.

Securities and assets for which market quotations are not readily available
are fair valued as determined by the Fund's Board of Trustees. Fair valuation
methodologies and procedures may include, but are not limited to: analysis and
review of available financial and non-financial information about the company;
comparisons to the valuation and changes in valuation of similar securities,
including a comparison of foreign securities to the equivalent U.S. dollar value
American Depositary Receipts securities at the close of the U.S. exchange; and
evaluation of any other information that could be indicative of the value of the
security.

7. CAPITALIZATION

The following table sets forth as of September 30, 2008: (1) the unaudited
capitalization of the B.B. Fund and the unaudited capitalization of the Mighty
Mites Fund, and (2) the unaudited pro forma combined capitalization of the
Mighty Mites Fund assuming the Reorganization has been approved and consummated.
If the Reorganization is consummated, the capitalizations are likely to be
different on March 27, 2009, as a result of daily share purchase and redemption
activity in the Funds and changes in NAV per share.

8. INVESTMENT ADVISER AND PORTFOLIO MANAGEMENT

Teton, with its principal offices located at One Corporate Center, Rye, New
York 10580-1422, serves as investment adviser to both Funds. Teton makes
investment decisions for the Funds and continuously reviews and administers the
Funds' investment programs and manages the Funds' operations under the general
supervision of each Fund's Board of Trustees. Teton is a Delaware corporation.
Teton is a subsidiary of GAMCO Investors, Inc. ("GBL"), a publicly held company
listed on the New York Stock Exchange.

As compensation for its services and the related expenses that Teton bears,
Teton is contractually entitled to an advisory fee, computed daily and payable
monthly, at annual rate of 1.00% of each Fund's average daily net assets. The
advisory fee (after waivers/reimbursement of expenses) paid by the Mighty Mites
Fund for the fiscal year ended September 30, 2008, was 1.00% of the Mighty Mites
Fund's average daily net assets. Until November 28, 2008, BB&A was the B.B.
Fund's investment adviser and for the fiscal year ended March 31, 2008, BB&A was
paid an advisory fee of 1.00% of the B.B. Fund's average net assets.

PORTFOLIO MANAGEMENT

Mario J. Gabelli, Walter K. Walsh, and Laura Linehan are primarily
responsible for the day-to-day management of the Funds and have been portfolio
managers of the Mighty Mites Fund since its inception. Mario J. Gabelli has been
Chairman, Chief Executive Officer, and Chief Investment Officer-Value Portfolios
of GBL and its affiliates since their organization. Walter K. Walsh was
Compliance Officer of Gabelli & Company, Inc. from 1994 through 2003, and
currently is a compliance consultant. Ms. Linehan previously worked in the
Alternative Investment Group of GBL. Prior to that, she was Director of Research
and Portfolio Manager for the Mighty Mites Fund and various other small-cap
portfolios until March 2003.

9. DISTRIBUTION

Foreside Distribution Services, L.P. (the "Distributor") is the exclusive
agent for distribution of shares of the B.B. Fund. The Distributor is obligated
to sell the shares of the B.B. Fund on a best efforts

COMBINED PROXY STATEMENT/PROSPECTUS

basis only against purchase orders for the shares. Shares of the B.B. Fund are
offered to the public on a continuous basis at NAV. The Distributor is a
registered broker-dealer and member of the Financial Industry Regulatory
Authority ("FINRA"). Under a distribution plan adopted in accordance with Rule
12b-1 under the 1940 Act, as amended, the B.B. Fund is authorized to reimburse
the Adviser, the Distributor or others for all expenses incurred by such parties
in the promotion and distribution of shares of the B.B. Fund up to 0.25% per
year of the average daily net assets of the B.B. Fund. The B.B. Fund's 12b-1
Plan is a reimbursement plan, which means that the fees paid by the B.B. Fund
under the plan are intended to reimburse the recipient for services rendered.

Gabelli & Company, Inc. ("Gabelli & Company"), a registered broker-dealer
and member of FINRA, acts as the distributor for the Mighty Mites Fund. As such,
Gabelli & Company is responsible for all purchases, sales, redemptions and other
transfers of shares of the Mighty Mites Fund. As distributor, Gabelli & Company
also provides certain administrative services for the Mighty Mites Fund. Shares
of the Mighty Mites Fund are offered for sale on a continuous basis at NAV.
Under a distribution plan adopted in accordance with Rule 12b-1 under the 1940
Act, as amended, the Mighty Mites Fund is authorized to pay 0.25% per year of
the average daily net assets to finance the distribution of the Mighty Mites
Fund shares. The Mighty Mites Fund's 12b-1 Plan is a compensation plan, which
means that the fees paid by the Mighty Mites Fund under the plan are intended to
compensate for services rendered, regardless of expenses actually incurred.

10. PURCHASE AND REDEMPTION PROCEDURES

PURCHASE, EXCHANGE, AND REDEMPTION OF SHARES

Procedures for the purchase, exchange and redemption of shares of the B.B.
Fund and the Mighty Mites Fund are substantially similar and the Mighty Mites
Fund procedures will remain in place for the combined fund. Shareholders should
refer to the Mighty Mites Fund Prospectus (a copy of which accompanies this
Combined Prospectus/Proxy Statement) and the B.B. Fund Prospectus for the
specific procedures applicable to purchases, exchanges and redemptions of shares
of each of the Funds. In addition to the policies described therein, certain
fees may be assessed in connection with the exchange and redemption of shares.
See "Comparison Fee Table and Examples" above.

The minimum initial investment for the B.B. Fund and the Mighty Mites Fund
are shown below. Both Funds have the right to waive account minimums if it is
economically feasible and determined to be in the best interests of the Funds'
shareholders. Each Fund has the right to reject any purchase order or limit or
suspend the offering of its shares. The B.B. Fund shareholders will not be
subject to the $10,000 requirement to open an account with the Mighty Mites
Fund; however, they will be subject to the other account minimums of the Mighty
Mites Fund shown below.

Automatic Investment Plan None $100 None

REDEMPTION INFORMATION

Differences in the redemption fees that apply to the Funds are as follows:

MIGHTY MITES FUND

You can redeem shares of the Mighty Mites Fund on any day the NYSE is open.
The Mighty Mites Fund may temporarily stop redeeming its shares when the NYSE is
closed or trading on the NYSE is restricted, when an emergency exists and the
Mighty Mites Fund cannot sell its shares or accurately determine the value of
its assets, or if the SEC orders the Mighty Mites Fund to suspend redemptions.

The Mighty Mites Fund redeems its shares based on the NAV next determined
after the time as of which the Mighty Mites Fund receives a redemption request
in proper form. See "Pricing of Fund Shares" in the Mighty Mites Fund prospectus
for a description of the calculation of NAV.

The Mighty Mites Fund is intended for long-term investors and not for those
who wish to trade frequently in Mighty Mites Fund shares. The Mighty Mites Fund
believes that excessive short-term trading of Mighty Mites Fund shares creates
risks for the Mighty Mites Fund and its long-term shareholders, including
interference with efficient portfolio management, increased administrative and
brokerage costs, and potential dilution in the value of Mighty Mites Fund
shares. In addition, because the Mighty Mites Fund may invest in foreign
securities traded primarily on markets that close prior to the time as of which
the Mighty Mites Fund determines its NAV, frequent trading by some shareholders
may, in certain circumstances, dilute the value of Mighty Mites Fund shares held
by other shareholders. This may occur when an event that affects the value of
the foreign security takes place after the close of the primary foreign market,
but before the time that the Mighty Mites Fund determines its NAV. Certain
investors may seek to take advantage of the fact that there will be a delay in
the adjustment of the market price for a security caused by this event until the
foreign market reopens (referred to as price arbitrage). If this occurs,
frequent traders who attempt this type of price arbitrage may dilute the value
of the Mighty Mites Fund shares to the extent they receive shares or proceeds
based upon NAVs that have been calculated using the closing market prices for
foreign securities, if those prices have not been adjusted to reflect a change
in the fair value of the foreign securities. In an effort to prevent price
arbitrage, the Mighty Mites Fund has procedures designed to adjust closing
market prices of foreign securities before it calculates its NAV when it
believes such an event has occurred that will have more than a minimal effect on
the NAV. Prices are adjusted to reflect what the Mighty Mites Fund believes are
the fair values of these foreign securities at the time the Mighty Mites Fund
determines its NAV (called fair value pricing). Fair value pricing, however,
involves judgments that are inherently subjective and inexact, since it is not
possible to always be sure when an event will affect a market price and to what
extent. As a result, there can be no assurance that fair value pricing will
always eliminate the risk of price arbitrage.

COMBINED PROXY STATEMENT/PROSPECTUS

In addition, the Mighty Mites Fund invests in small capitalization and
micro-capitalization securities. Such securities are typically less liquid and
more thinly-traded than securities of large capitalization issuers. Developments
affecting the issuer of the thinly-traded or less liquid security will not be
reflected in its market price until the security again trades in the
marketplace. Frequent traders may seek to exploit this delay by engaging in
price arbitrage, in this case by buying or selling shares of the Mighty Mites
Fund prior to the time of the adjustment of the market price of securities in
its portfolio. This may result in the dilution in the value of the Mighty Mites
Fund shares.

In order to discourage frequent short-term trading in its shares, the
Mighty Mites Fund imposes a 2.00% redemption fee (short-term trading fee) on
Class AAA Shares that are redeemed or exchanged within seven days or less after
the date of a purchase (the "Redemption Fee"). The Redemption Fee is calculated
based on the shares' aggregate NAV on the date of redemption and deducted from
the redemption proceeds. The Redemption Fee is not a sales charge; it is
retained by the Mighty Mites Fund, and does not benefit the Fund's Adviser or
any other third party. For purposes of computing the Redemption Fee, shares will
be redeemed in reverse order of purchase (the latest shares acquired will be
treated as being redeemed first). Redemptions to which the fee applies include
redemption of shares resulting from an exchange made pursuant to the Mighty
Mites Fund's exchange privilege. The Redemption Fee will not apply to
redemptions of shares where (i) the shares were purchased through automatic
reinvestment of dividends or other distributions, (ii) the redemption is
initiated by the Mighty Mites Fund, (iii) the shares were purchased through
programs that collect the redemption fees at the program level and remit them to
the Mighty Mites Fund, or (iv) the shares were purchased through programs that
the Adviser determines to have appropriate anti-short-term trading policies in
place.

While the Mighty Mites Fund has entered into information sharing agreements
with financial intermediaries which contractually require such financial
intermediaries to provide the Mighty Mites Fund with information relating to its
customers investing in the Mighty Mites Fund through non-disclosed or omnibus
accounts, the Mighty Mites Fund cannot guarantee the accuracy of the information
provided to it from financial intermediaries and may not always be able to track
short-term trading effected through these financial intermediaries. In addition,
because the Mighty Mites Fund is required to rely on information provided by the
financial intermediary as to the applicable redemption fee, the Mighty Mites
Fund cannot guarantee that the financial intermediary is always imposing such
fee on the underlying shareholder in accordance with the Mighty Mites Fund's
policies. Subject to the exclusions discussed above, the Mighty Mites Fund seeks
to apply these policies uniformly.

The Mighty Mites Fund continues to reserve all rights, including the right
to refuse any purchase request (including requests to purchase by exchange) from
any person or group who, in the Mighty Mites Fund's view, is likely to engage in
excessive trading or if such purchase is not in the best interest of the Mighty
Mites Fund and to limit, delay, or impose other conditions on exchanges or
purchases. The Mighty Mites Fund has adopted a policy of seeking to minimize
short-term trading of its shares and monitors purchase and redemption activities
to assist in minimizing short-term trading.

B.B. FUND

The B.B. Fund is intended to be a long-term investment. Excessive purchases
and redemptions, or exchanges, of shares of the B.B. Fund in an effort to take
advantage of short-term market fluctuations,

COMBINED PROXY STATEMENT/PROSPECTUS

known as "market timing," can interfere with long-term portfolio management
strategies and increase the expenses of the B.B. Fund, to the detriment of
long-term investors. For example, excessive redemption orders may require the
B.B. Fund to sell securities in its portfolio at inopportune times to fund
redemption payments. Accordingly, B.B. Board has adopted policies and procedures
that seek to restrict market timing activity. If management of the B.B. Fund
believes, in its sole discretion, that an investor is engaged in excessive
short-term trading or exchanges or is otherwise engaged in market timing
activity, the B.B. Fund may, with or without prior notice to the investor,
reject, limit, delay or impose conditions on further purchase or exchange orders
from that investor, or the B.B. Fund may close that investor's account, and the
B.B. Fund disclaims responsibility for any consequent losses that the investor
may incur. The B.B. Fund's response to any particular market timing activity
will depend on the facts and circumstances of each case, such as the extent and
duration of the market timing activity and the investor's trading history in the
B.B. Fund.

The B.B. Fund reviews trade and exchange orders for shares of the B.B. Fund
periodically to detect market-timing activity. It is difficult to distinguish
market-timing activity from trading that is not harmful, such as the technique
of dollar cost averaging or periodic rebalancing of portfolios. Consequently,
the B.B. Fund has not established a fixed number of trades or exchanges in a
given time period as a basis for identifying a market timer.

Some investors trade in shares of the B.B. Fund through omnibus accounts of
third parties (such as those of investment advisers and broker-dealers), and, if
the B.B. Fund identifies excessive trading in such an account, it may instruct
the third party to restrict the investor responsible for the excessive trading
from any further trading in the B.B. Fund. However, some omnibus accounts submit
to the B.B. Fund a daily aggregate purchase order and aggregate redemption order
reflecting the trade orders of multiple unidentified investors. Accordingly, the
B.B. Fund cannot identify individual investors engaged in market timing through
such omnibus accounts.

The B.B. Fund applies these policies and procedures to all investors it
believes to be engaged in market timing. It does not have any arrangements to
allow individual investors to trade frequently in shares of the B.B. Fund,
although it permits third party omnibus accounts submitting the aggregated
orders of multiple investors to trade on a daily basis in shares of the B.B.
Fund.

The B.B Fund assesses investors who redeem or exchange shares (other than
shares acquired through reinvestment of dividends or other distributions) held
by the investors for 60 days or less a redemption/exchange fee of 2% of the NAV
of the shares being redeemed or exchanged. The redemption/exchange fee is for
the benefit of the remaining shareholders of the B.B. Fund and is intended to
restrict market timing, encourage long-term investment, facilitate long-term
portfolio management strategies and compensate the B.B. Fund for transaction and
other expenses caused by early redemptions. In determining the holding period of
shares being redeemed or exchanged, the shares held the longest by the investor
will be deemed the first to be redeemed (the so-called first in, first out
method). The redemption/exchange fee will not be assessed on redemptions or
exchanges by (i) omnibus accounts of certain financial institutions or
intermediaries that are unable for administrative reasons to apply the
redemption/exchange fee to underlying shareholders, (ii) accounts in the event
of shareholder death and (iii) certain other accounts in the absolute discretion
of the B.B. Fund when a shareholder can demonstrate hardship. The B.B. Fund
reserves the right to modify or eliminate these waivers at any time.

+ Total return represents aggregate total return of a hypothetical $1,000
investment at the beginning of the period and sold at the end of the period
including reinvestment of distributions and does not reflect applicable
sales charges. Total return for a period of less than one year is not
annualized.

++ Effective in 2008, a change in accounting policy was adopted with regard to
the calculation of the portfolio turnover rate to include cash due to
mergers. Had this policy been adopted retroactively, the portfolio turnover
rate for the fiscal years ended September 30, 2007 and 2004 would have been
23% and 39%, respectively. The portfolio turnover rate for the fiscal years
ended 2006 and 2005 would have been as shown.

(a) Per share data is calculated using the average shares outstanding method.

(b) Due to capital share activity throughout the fiscal year, net investment
income per share and the ratio to average net assets are not necessarily
correlated among the different classes of shares.

(c) Prior to the period beginning October 1, 2005, fees and expenses were
voluntarily reduced and/or reimbursed. If such fee reductions and/or
reimbursements had not occurred, the ratio would have been as shown.

(d) Amount represents less than $0.005 per share.

(e) The fund incurred interest expense during the fiscal year ended September
30, 2006. If interest expense had not been incurred, the ratios of
operating expenses to average net assets would have been 1.57% (Class AAA),
1.82% (Class A), 2.32% (Class B and Class C), respectively. For the fiscal
years ended September 30, 2008 and 2007, the effect of interest expense was
minimal.

COMBINED PROXY STATEMENT/PROSPECTUS

THE BOARD UNANIMOUSLY RECOMMENDS
A VOTE "FOR" THE PROPOSAL.

II. VOTING INFORMATION

This Proxy Statement is being provided in connection with the solicitation
of proxies by the Board of the B.B. Trust to solicit your vote for the proposal
with respect to the Reorganization at a special meeting of shareholders of the
B.B. Fund (the "Special Meeting"). The Special Meeting will be held at the
offices of the B.B. Trust, One Corporate Center, Rye, New York 10580, on March
16, 2009, at 10:00 a.m. (Eastern Standard Time).

You may vote in one of three ways:

- complete and sign the enclosed proxy ballot and mail it to us in the
prepaid return envelope (if mailed in the United States);

- call the toll-free number printed on your proxy ballot; or

- attend the Special Meeting in person.

PLEASE NOTE THAT, TO VOTE VIA TELEPHONE, YOU WILL NEED THE "CONTROL NUMBER"
THAT APPEARS ON YOUR PROXY BALLOT.

You may revoke a proxy once it is given. If you desire to revoke a proxy,
you must submit a subsequent proxy or a written notice of revocation to the
Fund. You may also give written notice of revocation in person at the Special
Meeting. All properly executed proxies received in time for the Special Meeting
will be voted as specified in the proxy, or, if no specification is made, FOR
each proposal.

Only shareholders of record on January 16, 2009 (the "Record Date"), are
entitled to receive notice of and to vote at the Special Meeting or at any
adjournment thereof. Each whole share held as of the close of business on the
Record Date is entitled to one vote and each fractional share is entitled to a
proportionate fractional vote.

With respect to the proposal, one-third (1/3) of the shareholders of the
B.B. Fund entitled to vote must be present in person or by proxy to constitute a
quorum. When a quorum is present, the affirmative vote of the lesser of (1) 67%
or more of the shares of the B.B. Fund present or represented by proxy at the
Special Meeting, if holders of more than 50% of the B.B. Fund's outstanding
shares are present or represented by proxy, or (2) more than 50% of the B.B.
Fund's outstanding shares, is required to approve the Reorganization.

If a quorum of shareholders of the B.B. Fund is not present at the Special
Meeting, or if a quorum is present but sufficient votes to approve the proposal
described in this Combined Proxy Statement/Prospectus with respect to the B.B.
Fund are not received, the persons named as proxies may, but are under no
obligation to, propose one or more adjournments of the Special Meeting to permit
further solicitation of proxies. Any business that might have been transacted at
the Special Meeting with respect to the B.B. Fund may be transacted at any such
adjourned session(s) at which a quorum is present. The Special Meeting may be
adjourned from time to time by a majority of the votes of the B.B. Fund properly
cast upon the question of adjourning the Special Meeting to another date and

COMBINED PROXY STATEMENT/PROSPECTUS

time, whether or not a quorum is present, and the Special Meeting may be held as
adjourned without further notice. The persons named in the proxy will vote in
favor of such adjournment those shares that they are entitled to vote if such
adjournment is necessary to obtain a quorum or to obtain a favorable vote on the
proposal. The persons named in the proxy will vote against adjournment those
shares that they are entitled to vote if the shareholder proxies instruct the
persons named in the proxy to vote against the proposal.

All proxies voted, including abstentions and broker non-votes (shares held
by brokers or nominees where the underlying holder has not voted and the broker
does not have discretionary authority to vote the shares), will be counted
toward establishing a quorum. In addition, under the rules of the New York Stock
Exchange, if a broker has not received instructions from beneficial owners or
persons entitled to vote and the proposal to be voted upon may "affect
substantially" a shareholder's rights or privileges, the broker may not vote the
shares as to that proposal even if it has discretionary voting power. As a
result, these shares also will be treated as broker non-votes for purposes of
proposals that may "affect substantially" a shareholder's rights or privileges
(but will not be treated as broker non-votes for other proposals, including
adjournment of the Special Meeting).

Abstentions and broker non-votes will be treated as shares voted against a
proposal. Treating broker non-votes as votes against a proposal can have the
effect of causing shareholders who choose not to participate in the proxy vote
to prevail over shareholders who cast votes or provide voting instructions to
their brokers or nominees. In order to prevent this result, the B.B. Fund may
request that selected brokers or nominees refrain from returning proxies on
behalf of shares for which voting instructions have not been received from
beneficial owners or persons entitled to vote. The B.B. Fund also may request
that selected brokers or nominees return proxies on behalf of shares for which
voting instructions have not been received if doing so is necessary to obtain a
quorum.

Approval of a proposal will occur only if a sufficient number of votes are
cast "FOR" the proposal. If shareholders of the B.B. Fund do not vote to approve
the Reorganization, the Board of the B.B. Fund will consider other possible
courses of action in the best interests of the B.B. Fund's shareholders. If
sufficient votes in favor of the Reorganization are not received by the time
scheduled for the Special Meeting, the persons named as proxies or any officer
present entitled to preside or act as Secretary of such meeting may propose one
or more adjournments of the Special Meeting to permit further solicitation of
proxies. In determining whether to adjourn the Special Meeting, the following
factors may be considered: the percentage of votes actually cast, the percentage
of negative votes actually cast, the nature of any further solicitation and the
information to be provided to shareholders with respect to the reasons for the
solicitation. The costs of any additional solicitation and of any adjourned
session will be borne by Teton.

A shareholder of the B.B. Fund who objects to the proposed Reorganization
will not be entitled under either Delaware law or The B.B. Funds' Amended and
Restated Declaration of Trust to demand payment for, or an appraisal of, his or
her shares. Shareholders, however, should be aware that the Reorganization as
proposed is not expected to result in recognition of gain or loss to
shareholders for federal income tax purposes. If the Reorganization is
consummated, shareholders will be free to redeem the shares of the Mighty Mites
Fund that they receive in the transaction at their then current NAV. Shares of
the B.B. Fund may be redeemed at any time prior to the consummation of the
Reorganization at their NAV. Shareholders of the B.B. Fund may wish to consult
their tax advisors as to any different consequences of redeeming their shares
prior to the Reorganization or exchanging such shares in the Reorganization.

COMBINED PROXY STATEMENT/PROSPECTUS

A. METHOD AND COST OF SOLICITATION

This Combined Proxy Statement/Prospectus is being sent to you in connection
with the solicitation of proxies by the Board of the B.B. Fund for use at the
Special Meeting. The B.B. Fund expects that the solicitation of proxies will be
primarily by mail and telephone. The solicitation may also include facsimile or
oral communications by certain employees of the Adviser, who will not be paid
for these services. In addition, The Altman Group has been engaged to assist in
the solicitation of proxies, at an estimated cost of $32,000. Teton will bear
the costs of the Special Meeting, including legal costs and the cost of the
solicitation of proxies.

B. RIGHT OF REVOCATION

Any shareholder giving a proxy may revoke it before it is exercised at the
Special Meeting, either by providing written notice to the B.B Fund, by
submission of a later-dated, duly executed proxy or by voting in person at the
Special Meeting. A prior proxy can also be revoked by proxy voting again through
the toll-free number listed in the enclosed Voting Instructions. If not so
revoked, the votes will be cast at the Special Meeting and any postponements or
adjournments thereof. Attendance by a shareholder at the Special Meeting does
not, by itself, revoke a proxy.

C. VOTING SECURITIES AND PRINCIPAL HOLDERS

Shareholders of the B.B. Fund at the close of business on the Record Date
will be entitled to be present and vote at the Special Meeting. As of that date,
there were 9,778,616.255 outstanding shares of the B.B. Fund. Also as of the
Record Date, there were 6,309,979.587 outstanding shares of the Mighty Mites
Fund (there were 5,112,839.170 outstanding Class AAA shares).

As of December 31, 2008, the B.B. Fund's shareholders of record and/or
beneficial owners (to the B.B. Fund's knowledge) who owned five percent or more

D. INTEREST OF CERTAIN PERSONS IN THE TRANSACTION

A beneficial owner of 25% or more of a voting security of a Fund is
presumed to have "control" of the Fund for purposes of the 1940 Act, absent a
determination to the contrary by the SEC. A person who controls the B.B. Fund or
the Mighty Mites Fund could have effective control over the outcome of matters
submitted to a vote of shareholders of the Funds. Based on the information
provided above, as of December 31, 2008, no person owned a

COMBINED PROXY STATEMENT/PROSPECTUS

controlling interest in the B.B. Fund. Based on the information provided above,
as of December 31, 2008, no person owned a controlling interest in the Mighty
Mites Fund.

III. FURTHER INFORMATION ABOUT THE B.B. FUND AND THE MIGHTY MITES FUND

Reports, proxy statements, registration statements and other information
filed by the Funds may be inspected without charge and copied at the public
reference facilities maintained by the SEC at 100 F Street, N.E., Washington, DC

IV. MISCELLANEOUS MATTERS

A. OTHER BUSINESS

The Board of the B.B. Trust knows of no other business to be brought before
the Special Meeting. If any other matters come before the Meeting, the Board of
the B.B. Trust intends that proxies that do not contain specific restrictions to
the contrary will be voted on those matters in accordance with the judgment of
the persons named in the enclosed form of proxy.

B. NEXT MEETING OF SHAREHOLDERS

The B.B. Fund is not required and does not intend to hold annual or other
periodic meetings of shareholders except as required by the 1940 Act. By
observing this policy, the B.B. Fund seeks to avoid the expenses customarily
incurred in the preparation of proxy material and the holding of shareholder
meetings, as well as the related expenditure of staff time. If the
Reorganization is not completed, the next meeting of the shareholders of the
B.B. Fund will be held at such time as the Board of Trustees of the B.B. Trust
may determine or at such time as may be legally required. Any shareholder
proposal intended to be presented at such meeting must be received by the B.B.
Trust at its office at a reasonable time before the B.B. Trust begins to print
and mail its proxy, as determined by the Board of Trustees of the B.B. Trust, to
be included in the B.B. Fund's proxy statement and form of proxy relating to
that meeting, and must satisfy all other legal requirements.

C. LEGAL MATTERS

Certain legal matters in connection with the tax consequences of the
Reorganization will be passed upon by Paul, Hastings, Janofsky & Walker LLP.

D. INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The financial statements of the B.B. Fund for the year ended March 31,
2008, contained in the B.B. Trust's 2008 Annual Report to Shareholders, have
been audited by PricewaterhouseCoopers LLP, independent registered public
accounting firm, which are incorporated herein by reference, and have been so
incorporated in reliance upon the report of such firm given on their authority
as experts in accounting and auditing.

EXECUTION VERSION

AGREEMENT AND PLAN OF REORGANIZATION AND LIQUIDATION

AGREEMENT AND PLAN OF REORGANIZATION AND LIQUIDATION (the "Agreement")
dated this 28th day of November, 2008, by and between the B.B. Micro-Cap Growth
Fund (formerly the Bjurman, Barry Micro-Cap Growth Fund), a series of The B.B.
Funds (formerly The Bjurman, Barry Funds) (the "Acquired Fund"), a Delaware
statutory trust, and the GAMCO Westwood Mighty Mites(SM) Fund, a series of the
GAMCO Westwood Funds (the "Acquiring Fund"), a Massachusetts business trust.
Teton Advisors, Inc. ("Teton"), a Delaware corporation, is a party to this
Agreement with respect to Section 14(b) hereof only.

WITNESSETH:

WHEREAS, the parties are each open-end investment management
companies; and

WHEREAS, the parties hereto desire to provide for the acquisition by
the Acquiring Fund of all of the assets and known and disclosed liabilities of
the Acquired Fund solely in exchange for the Class AAA shares of beneficial
interest (par value $.001) ("Class AAA Shares") of the Acquiring Fund, which
Class AAA Shares of the Acquiring Fund will thereafter be distributed by the
Acquired Fund pro rata to its shareholders in complete liquidation and complete
cancellation of its shares;

NOW, THEREFORE, in consideration of the mutual promises herein
contained, the parties agree as follows:

1. The parties hereto hereby adopt this Agreement, pursuant to section
368(a) of the Internal Revenue Code of 1986, as amended (the "Code") as follows:
the reorganization will be comprised of the acquisition by the Acquiring Fund of
all of the properties, assets and known and disclosed liabilities of the
Acquired Fund, which will be retained by the Acquiring Fund for the benefit of
its shareholders, solely in exchange for Class AAA Shares of the Acquiring Fund,
followed by the distribution of such Acquiring Fund Class AAA Shares to the
shareholders of the Acquired Fund in exchange for their shares of the Acquired
Fund, and the liquidation and dissolution of the Acquired Fund all upon and
subject to the terms of the Agreement hereinafter set forth.

The share transfer books of the Acquired Fund will be permanently
closed on the Valuation Date (as hereinafter defined) and only redemption
requests made by shareholders of the Acquired Fund pursuant to Section 22(e) of
the Investment Company Act of 1940 (the "Act") received in proper form on or
prior to the close of business on the Valuation Date shall be fulfilled by the
Acquired Fund; redemption requests received by the Acquired Fund after that date
shall be treated as requests for the redemption of the Class AAA Shares of the
Acquiring Fund to be distributed to the shareholder in question as provided in
Section 5.

2. On the Closing Date (as hereinafter defined), all of the assets and
known and disclosed liabilities of the Acquired Fund on that date shall be
delivered to the Acquiring Fund; and the number of Class AAA Shares of the
Acquiring Fund having an aggregate net asset value equal to the value of the net
assets of the Acquired Fund will be transferred and delivered to the Acquired
Fund.

3. The net asset value of Class AAA Shares of the Acquiring Fund and
the value of the net assets of the Acquired Fund to be transferred shall in each
case be determined as of the

close of business of the New York Stock Exchange on the Valuation Date. The
computation of the net asset value of the Class AAA Shares of the Acquiring Fund
and the shares of the Acquired Fund shall be done in the manner used by the
Acquiring Fund and the Acquired Fund, respectively, in the computation of such
net asset value per share as set forth in their respective prospectuses. The
methods used by the Acquiring Fund in such computation shall be applied to the
valuation of the assets of the Acquired Fund to be transferred to the Acquiring
Fund.

The Acquired Fund shall declare and pay, immediately prior to the
Valuation Date, a dividend or dividends which, together with all previous such
dividends, shall have the effect of distributing to the Acquired Fund's
shareholders all of the Acquired Fund's investment company taxable income as
defined in Section 852(b) of the Code for taxable years ending on or prior to
the Closing Date (computed without regard to any deduction for dividends paid)
and all of its net capital gain, if any, realized in taxable years ending on or
prior to the Closing Date (after reduction for any capital loss carryforward)
(the "RIC dividend").

4. The closing shall be at the office of Teton at One Corporate
Center, Rye, New York 10580, at 10:00 a.m., Eastern Time on April 24, 2009, or
at such other time, date or place as the parties may designate or as provided
below (the "Closing Date"). The business day preceding the Closing Date is
herein referred to as the "Valuation Date."

In the event that on the Valuation Date either party has, pursuant to
the Act or any rule, regulation or order thereunder, suspended the redemption of
its shares or postponed payment therefor, the Closing Date shall be postponed
until the first business day after the date when both parties have ceased such
suspension or postponement; PROVIDED, HOWEVER, that if such suspension shall
continue for a period of 60 days beyond the Valuation Date, then the other party
to this Agreement shall be permitted to terminate this Agreement without
liability to either party for such termination.

5. As soon as practicable after the Closing Date, the Acquired Fund
shall distribute on a PRO RATA basis to those persons who were shareholders of
the Acquired Fund as of the close of business on the Valuation Date the Class
AAA Shares of the Acquiring Fund received by the Acquired Fund pursuant to the
Agreement in liquidation and cancellation of the outstanding shares of the
Acquired Fund. For the purpose of the distribution by the Acquired Fund of such
Class AAA Shares of the Acquiring Fund to its shareholders, the Acquiring Fund
will promptly cause its transfer agent to: (a) credit an appropriate number of
Class AAA Shares of the Acquiring Fund, on the books of the Acquiring Fund, to
each shareholder of the Acquired Fund, in accordance with a list (the
"Shareholder List") of its shareholders received from the Acquired Fund; and (b)
confirm an appropriate number of Class AAA Shares of the Acquiring Fund to each
shareholder of the Acquired Fund. No certificates for Class AAA Shares of the
Acquiring Fund will be issued in connection with the reorganization contemplated
hereby.

The Shareholder List shall indicate, as of the close of business on
the Valuation Date, the name and address of each shareholder of the Acquired
Fund, indicating his or her share balance. The Acquired Fund agrees to supply
the Shareholder List to the Acquiring Fund not later than the Closing Date.

6. As soon as practicable, and in any event within one year after the
closing, the Acquired Fund shall (a) effect its dissolution with the proper
state authorities, terminate its registration under the Act and file a final
annual report on Form N-SAR with the Securities and Exchange Commission under
that Act; and (b) either pay or make provision for payment of all of its
liabilities not transferred to the Acquiring Fund, if any, and taxes, if any.

7. Subsequent to the date of approval by shareholders of the Acquired
Fund of the transactions contemplated by this Agreement and prior to the Closing
Date, there shall be coordination between the parties as to their respective
portfolios so that, after the closing, the Acquiring Fund will be in compliance
with all of its investment policies and restrictions. At the time of delivery of
portfolio securities for examination as provided in Section 8, the Acquired Fund
shall deliver to the Acquiring Fund two copies of a list setting forth the
securities then owned by the Acquired Fund and the respective adjusted federal
income tax basis thereof, including any additional information relevant to the
characterization of such securities or distributions thereon in the hands of the
Acquiring Fund.

8. Portfolio securities or written evidence acceptable to the
Acquiring Fund of record ownership thereof by The Depository Trust Company or
through the Federal Reserve Book Entry System or any other depository approved
by the Acquired Fund pursuant to Rule 17f-4 under the Act shall be presented by
the Acquired Fund to the Acquiring Fund or, at its request, to its custodian,
for examination no later than five business days preceding the Closing Date, and
shall be delivered, or transferred by appropriate transfer or assignment
documents, by the Acquired Fund on the Closing Date to the Acquiring Fund, duly
endorsed in proper form for transfer in such condition as to constitute good
delivery thereof in accordance with the custom of brokers and shall be
accompanied by all necessary state transfer stamps, if any, or a check for the
appropriate purchase price thereof. The cash delivered, if any, shall be in the
form of certified or bank cashiers checks or by bank wire payable to the order
of the Acquiring Fund. The number of Class AAA Shares (to the nearest whole
share) of the Acquiring Fund being delivered against the securities and cash of
the Acquired Fund, registered in the name of the Acquired Fund, shall be
delivered to the Acquired Fund on the Closing Date. Such Class AAA Shares shall
thereupon be assigned by the Acquired Fund to its shareholders so that the Class
AAA Shares of the Acquiring Fund may be distributed as provided in Section 5.

If, at the Closing Date, the Acquired Fund is unable to make delivery
under this Section 8 to the Acquiring Fund of any of its portfolio securities or
cash for the reason that any of such securities purchased by the Acquired Fund,
or the cash proceeds of a sale of portfolio securities, prior to the Closing
Date have not yet been delivered to it or the Acquired Fund's custodian, then
the delivery requirements of this Section 8 with respect to said undelivered
securities or cash will be waived and the Acquired Fund will deliver to the
Acquiring Fund by or on the Closing Date and with respect to said undelivered
securities or cash executed copies of an agreement or agreements of assignment
in a form reasonably satisfactory to the Acquiring Fund, together with such
other documents, including a due bill or due bills and brokers' confirmation
slips as may reasonably be required by the Acquiring Fund.

9. The Acquired Fund will use its best efforts to discharge all known
liabilities, so far as may be possible, prior to the Closing Date. The Acquiring
Fund shall assume only those liabilities, expenses, costs, charges and reserves
reflected on a Statement of Assets and Liabilities of the Acquired Fund,
prepared on behalf of the Acquired Fund, as of the Valuation Date, in accordance
with generally accepted accounting principles consistently applied from the
prior audit period. The Acquiring Fund shall also assume any known or disclosed
liabilities incurred by or on behalf of the Acquired Fund specifically arising
from or relating to the operations and/or transactions of the Acquired Fund
prior to and including the Valuation Date which are not reflected on the
Statement of Assets and Liability of the Acquired Fund described herein.

1. BASIS OF COMBINATION

The Proforma Statement of Combined Assets and Liabilities, including the
Schedule of Investments as of September 30, 2008 and the related Statement of
Combined Operations for the twelve months ended September 30, 2008 ("Proforma
Statements") reflect the accounts of GAMCO Westwood Mighty Mites(SM) Fund
("Mighty Mites Fund"), a multiclass series of The GAMCO Westwood Funds and the
B.B. Micro-Cap Fund (the "B.B. Fund"), a series of The B.B. Funds. The Proforma
Statement of Combined Assets and Liabilities has been restated to reflect a tax
free exchange of B.B. Fund shares for Mighty Mites Fund's no-load Class AAA
Shares as of the close of business on September 30, 2008 and to give effect to
the proposed transfer of all assets and liabilities of the B.B. Fund in exchange
for Class AAA Shares of the Mighty Mites Fund. The Mighty Mites Fund is the
surviving fund.

The Mighty Mites Fund's adviser, Teton Advisors, Inc. ("Teton"), will pay all
the costs of the Special Meeting associated with the reorganization, including
legal, proxy and solicitation expenses.

The Proforma Statements should be read in conjunction with the historical
financial statements of the Mighty Mites Fund and the B.B. Fund included in
their respective Statements of Additional Information.

2. SECURITY VALUATION

Portfolio securities listed or traded on a nationally recognized securities
exchange or traded in the U.S. over-the-counter market for which market
quotations are readily available are valued at the last quoted sale price or a
market's official closing price as of the close of business on the day the
securities are being valued. If there were no sales that day, the security is
valued at the average of the closing bid and asked prices or, if there were no
asked prices quoted on that day, then the security is valued at the closing bid
price on that day. If no bid or asked prices are quoted on such day, the
security is valued at the most recently available price or, if the Board of
Trustees (the "Board") so determines, by such other method as the Board shall
determine in good faith to reflect its fair market value. Portfolio securities
traded on more than one national securities exchange or market are valued
according to the broadest and most representative market, as determined by
Teton.

Portfolio securities primarily traded on a foreign market are generally valued
at the preceding closing values of such securities on the relevant market, but
may be fair valued pursuant to procedures established by the Board if market
conditions change significantly after the close of the foreign market but prior
to the close of business on the day the securities are being valued. Debt
instruments with remaining maturities of 60 days or less that are not credit
impaired are valued at amortized cost, unless the Board determines such amount
does not reflect the securities' fair value, in which case these securities will
be fair valued as determined by the Board. Debt instruments having a maturity
greater than 60 days for which market quotations are readily available are
valued at the average of the latest bid and asked prices. If there were no asked
prices quoted on such day, the security is valued using the closing bid price.
Futures contracts are valued at the closing settlement price of the exchange or
board of trade on which the applicable contract is traded.

Securities and assets for which market quotations are not readily available are
fair valued as determined by the Board.

3. CAPITAL SHARES

The Pro Forma Combined net asset value per share assumes the issuance of
additional shares of the Mighty Mites Fund which would have been issued at
September 30, 2008, in connection with the proposed reorganization. The amount
of additional Class AAA Shares assumed to be issued was calculated based on the
September 30, 2008, net asset value per share of the Mighty Mites Fund ($13.41).

The Pro Forma number of shares outstanding are determined as follows:

Class AAA Shares of the Mighty Mites Fund 4,162,260
Additional Class AAA Shares to be issued to the B.B. Fund: 9,288,054
Pro Forma Shares Outstanding: 13,450,314

The Pro Forma Statements assume that all shares of the B.B. Fund
outstanding on September 30, 2008, were exchanged, tax free, for Class AAA
Shares of the Mighty Mites Fund.

4. PRO FORMA OPERATING EXPENSES

The Pro Forma Statement of Operations assumes expense adjustments based on the
agreements of the Mighty Mites Fund, the surviving entity. Certain accounts have
been adjusted to reflect the expense of the combined entity more closely. Pro
Forma operating expenses include the expenses of the Mighty Mites Fund and the
B.B. Fund combined, adjusted for certain items which are factually supportable.
All fees other than trustee fees and expenses have been charged to the combined
entity based upon the contracts in effect for the Mighty Mites Fund at the level
of assets of the combined fund for the stated period.

5. PROVISION FOR INCOME TAXES

The Mighty Mites Fund intends to continue to qualify as a regulated investment
company under Subchapter M of the Internal Revenue Code of 1986, as amended (the
"Code"). It is the policy of the Mighty Mites Fund to comply with the
requirements of the Code applicable to regulated investment companies and to
distribute substantially all of the Fund's net investment company taxable income
and net capital gains. Therefore, no provision for federal income taxes is
required.
