Dear Fellow Shareholder:

As an investor in the John Hancock Bank and Thrift Opportunity Fund, you are
cordially invited to attend the annual shareholder meeting on Thursday, March
18, 2004 at 9:00 A.M., Eastern Time, to be held at John Hancock Funds, 101
Huntington Avenue, Boston, MA 02199.

The proposals set forth in the enclosed proxy statement are routine items. A
routine item is one which occurs annually and makes no fundamental or material
changes to a fund's investment objectives, policies or restrictions, or to the
investment management contracts.

Elect your fund's Board of Trustees

Proposal number one asks you to elect three Trustees to serve until their
respective successors are elected and qualified. Your proxy statement includes
a brief description of each nominee's background.

Ratify the Trustees' selection of public accountants

Proposal number two asks you to ratify or reject the Trustees' selection of
Deloitte & Touche LLP as the fund's independent public accountants for the
fund's current fiscal year. Deloitte & Touche LLP has been the fund's
independent public accountants since the fund's inception.

Your vote is important!

Please complete the enclosed proxy ballot form, sign it and mail it to us
immediately. For your convenience, a postage-paid return envelope has been
provided. Your prompt response will help avoid the cost of additional mailings
at your fund's expense.

between 9:00 A.M. and 7:00 P.M., Eastern Time.

Thank you in advance for your prompt action on this very important matter.

                            To Be Held March 18, 2004

before the meeting, or if attending the meeting and voting in person, by
notifying the fund's secretary (without complying with any formalities) at any
time before your proxy is voted.

Record Ownership

     The Trustees have fixed the close of business on January 12, 2004 as the
record date to determine which shareholders are entitled to vote at the meeting.
Shareholders are entitled to one vote per share on all business relating to the
fund at the annual meeting or any postponements. On the record date, there were
84,400,000 shares of beneficial interest of the fund outstanding.

     The fund's management does not know of anyone who beneficially owned more
than 5% of the fund's shares outstanding on the record date except for Deutsche
Bank AK, 31 West 52nd Street, New York, NY 10019, which holds 7.662%.
(Beneficial ownership means voting power and/or investment power, which includes
the power to dispose of shares.)

                                  PROPOSAL 1

                             ELECTION OF TRUSTEES

General

     The fund's Board of Trustees consists of eleven members. The Board is
divided into three staggered term classes, two containing four Trustees each and
one containing three Trustees. The term of one class expires each year, and no
term continues for more than three years after the applicable election. Each
class of Trustees will stand for election at the conclusion of their respective
three-year terms. Classifying the Trustees in this manner may prevent
replacement of a majority of the Trustees for up to a two-year period.

     As of the date of this proxy, each nominee for election currently serves as
a Trustee of the fund. Using the enclosed proxy card, you may authorize the
proxies to vote your shares for the nominees or you may withhold


                                        1


from the proxies authority to vote your shares for one or more of the nominees.
If no contrary instructions are given, the proxies will vote FOR the nominees.
Each of the nominees has consented to his or her nomination and has agreed to
serve if elected. If, for any reason, any nominee should not be available for
election or able to serve as a Trustee, the proxies will exercise their voting
power in favor of a substitute nominee, if any, as the fund's Trustees may
designate. The fund has no reason to believe that it will be necessary to
designate a substitute nominee.

Proposal 1

     Ms. McGill Peterson and Messrs. Pruchansky and Smith are the current
nominees for election.

Vote Required For Proposal 1

     The vote of a plurality of the votes cast by the shares of the fund is
sufficient to elect the nominees.

Information Concerning Trustees

     The following table sets forth certain information regarding the nominees
for election to the Board. The table also shows his or her principal occupation
or employment and other directorships during the past five years and the number
of John Hancock funds overseen by the Trustees. The table also lists the
Trustees who are not currently standing for election: The term of Messrs.
Carlin, Cunningham, DeCiccio and Toolan will expire at the 2005 annual meeting,
and the term of Ms. Ford Goldfarb, Messrs. Dion, Ladner and Moore will expire at
the 2006 annual meeting.

Compliance Officer


(1)  Business address for independent and interested Trustees and officers is
     101 Huntington Avenue, Boston Massachusetts 02199.

     The fund's Board of Trustees currently has four standing Committees: The
Audit Committee, the Administration Committee, the Contracts/Operations
Committee and the Investment Performance Committee. Each Committee is comprised
of Independent Trustees who are not "interested persons."

     The Board of Trustees held six meetings during the fund's fiscal year ended
October 31, 2003. No Trustees, except Mr. DeCiccio, attended fewer than 75% of
the aggregate of (i) the total number of meetings of the Trustees of the fund
and (2) the total number of meetings held by all committees of the Trust on
which they serve. Mr. DeCiccio attended more than 50% of the meetings.

     The Board of Trustees has an Audit Committee consisting of Messrs. Ladner,
Moore and Toolan and Ms. McGill Peterson. All members of the Audit Committee are
Independent under the New York Stock Exchange's Revised Listing Rules, and each
member is financially literate with at least one having accounting or financial
management expertise. The Board has adopted a written charter for the Audit
Committee, which is attached as Exhibit A. The Audit Committee held four
meetings during the fund's 2003 fiscal year. The Audit Committee recommends to
the full board the appointment of outside auditors for the fund, oversees and
monitors the audit of the fund, communicates with both the independent auditors
and inside auditors on a regular basis and provides a forum for the auditors to
report and discuss any matters they deem appropriate at any time. The Audit
Committee reports that it has (1) reviewed and discussed the fund's audited
financial statements with management; (2) discussed with the independent
auditors the matters relating to the quality of the fund's financial reporting
as required by SAS 61;


                                        7


(3) received written disclosures and an independence letter from the independent
auditors required by ISB Standard No. 1, and discussed with the auditors their
independence; and (4), based on these discussions, recommended to the Board that
the fund's financial statements be included in the fund's annual report for the
last fiscal year.

     The Board of Trustees has a Contracts/Operations Committee. The
Contracts/Operations Committee members are Messrs. Carlin, Pruchansky and Smith.
The Contract/Operations Committee held six meetings during the fund's 2003
fiscal year. The Contracts/Operations Committee oversees the initiation,
operation and renewal of the various contracts between the fund and other
entities. These contracts include advisory and subadvisory agreements, custodial
and transfer arrangements and arrangements with other service providers.

     The Board of Trustees has an Investment Performance Committee. The
Investment Performance Committee members are Messrs. Cunningham and Dion. The
Investment Performance Committee held four meetings during the fund's 2003
fiscal year. The Investment Performance Committee monitors and analyzes the
performance of the fund generally, consults with the Adviser as necessary with
respect to matters considered to require special attention and reviews peer
groups and other comparative standards as necessary.

     The Board of Trustees has an Administration Committee, which among other
things, serves as a nominating committee. The Administration Committee members
are Messrs. Carlin, Cunningham, Dion, Ladner, Moore, Purchansky, Smith, Toolan
and Ms. McGill Peterson. All members of the Administration Committee are
independent under the New York Stock Exchange's Revised Listing Rules and are
not interested persons, as defined in the Investment Company Act of 1940, as
amended, of John Hancock or the Fund (the "Independent Trustees"). The Board has
adopted a written charter for the Administration Committee, which is attached as
Exhibit B to this proxy statement. The Administration Committee held six
meetings during the Fund's 2003 fiscal year. The Administration Committee
selects and nominates for appointment and election candidates to serve as
Trustees who are Independent Trustees. The Trustees who are not Independent
Trustees and the officers of the Fund are nominated and selected by the Board.

     The Administration Committee does not have at this time formal criteria for
the qualifications of candidates to serve as an Independent Trustee, although
the Administration Committee may develop them in the future. In reviewing a
potential nominee and in evaluating the renomination of current Independent
Trustees, the Administration Committee has historically applied the following
criteria: (i) the nominee's reputation for integrity, honesty and adherence to
high ethical standards, (ii) the nominee's business acumen, experience and
ability to exercise sound judgments, (iii) a commitment to understand the Fund
and the responsibilities of a trustee of an investment company, (iv) a
commitment to regularly attend and participate in meetings of the Board and its
committees, (v) the ability to understand potential conflicts of interest
involving management of the Fund and to act in the interests of all
shareholders, and (vi) the absence of a real or apparent conflict of interest
that would impair the nominee's ability to represent the interests of all the
shareholders and to fulfill the responsibilities of an Independent Trustee. The
Administration Committee does not necessarily place the same emphasis on each
criteria and each nominee may not have each of these qualities. The
Administration Committee does not discriminate on the basis of race, religion,
national origin, sex, sexual orientation, disability or any other basis
proscribed by law.

     As long as an existing Independent Trustee continues, in the opinion of the
Administration Committee, to satisfy these criteria, the Fund anticipates that
the Committee would favor the renomination of an existing Trustee rather than a
new candidate. Consequently, while the Administration Committee will consider
nominees recommended by shareholders to serve as trustees, the Administration
Committee may only act upon such recommendations if there is a vacancy on the
Board or the Administration Committee determines that the selection of a new or
additional Independent Trustee is in the best interests of the Fund. In the
event that a vacancy arises or a change in Board membership is determined to be
advisable, the Administration Committee will, in addition to


                                        8


any shareholder recommendations, consider candidates identified by other means,
including candidates proposed by members of the Administration Committee. While
it has not done so in the past, the Administration Committee may retain a
consultant to assist the Committee in a search for a qualified candidate.

     Any shareholder recommendation must be submitted in compliance with all of
the pertinent provisions of Rule 14a-8 under the Securities Exchange Act of 1934
to be considered by the Administration Committee. In evaluating a nominee
recommended by a shareholder, the Administration Committee, in addition to the
criteria discussed above, may consider the objectives of the shareholder in
submitting that nomination and whether such objectives are consistent with the
interests of all shareholders. If the Board determines to include a
shareholder's candidate among the slate of nominees, the candidate's name will
be placed on the Fund's proxy card. If the Administration Committee or the Board
determines not to include such candidate among the Board's designated nominees
and the shareholder has satisfied the requirements of Rule 14a-8, the
shareholder's candidate will be treated as a nominee of the shareholder who
originally nominated the candidate. In that case, the candidate will not be
named on the proxy card distributed with the Fund's proxy statement. Each of the
nominees for election as Trustee was recommended by the Administration
Committee.

     Shareholders may communicate with the members of the Board as a group or
individually. Any such communication should be sent to the Board or an
individual Trustee c/o the secretary of the Fund at the address on the notice of
this meeting. The Secretary may determine not to forward any letter to the
members of the Board that does not relate to the business of the Fund. Ms. Ford
Goldfarb typically attends shareholder meetings and other members of the Board
may, but generally do not, attend.

(1)  The amounts reflect the aggregate dollar range of equity securities
     beneficially owned by the Trustees in the fund and in all John Hancock
     funds overseen by each Trustee. For each Trustee, the amounts reflected
     include share equivalents of certain John Hancock funds in which the
     Trustee is deemed to be invested pursuant to the Deferred Compensation Plan
     for Independent Trustees, as more fully described under "Remuneration of
     Officers and Trustees". The information as to beneficial ownership is based
     on statements furnished to the fund by the Trustees. Each of the Trustees
     has all voting and investment powers with respect to the shares indicated.
     None of the Trustees beneficially owned individually, and the Trustees and
     executive officers of the funds as a group did not beneficially own, in
     excess of one percent of the outstanding shares of any fund.

Compliance with Section 16(a) Reporting Requirements

     Section 16(a) of the Securities Exchange Act of 1934 requires the fund's
executive officers, Trustees and persons who own more than 10% of the fund's
shares ("10% Shareholders") to file reports of ownership and changes in
ownership with the Securities and Exchange Commission ("SEC"). Executive
officers, Trustees and 10% Shareholders are required by SEC regulations to
furnish the fund with copies of all Section 16(a) forms they file. Based solely
on a review of the copies of these reports furnished to the fund and
representations that no other reports were required to be filed, the fund
believes that during the past fiscal year its executive officers, Trustees and
10% Shareholders complied with all applicable Section 16(a) filing requirements.

Remuneration of Trustees and Officers

     The following table provides information about the compensation paid by the

the fund's officers are interested persons of the Adviser, are compensated by
the Adviser and/or its affiliates and receive no compensation from the fund for

(1)  The total compensation paid by the John Hancock fund complex to the
     Independent Trustees for the calendar year ended December 31, 2003. All the
     Independent Trustees are Trustees of 30 funds in the John Hancock fund
     complex, except for Ms. McGill Peterson and Mr. Moore, who are Trustees of
     29 funds.
*    As of December 31, 2003, the value of the aggregate accrued deferred
     compensation amount from all funds in the John Hancock fund complex for Mr.
     Cunningham was $563,218, for Mr. Dion was $193,220, for Mr. Moore was
     $248,464, for Mr. Pruchansky was $150,981, for Mr. Smith was $276,224 and
     for Mr. Toolan was $633,254 under the John Hancock Deferred Compensation
     Plan for Independent Trustees (the "Plan"). Under the Plan, an Independent
     Trustee may elect to have his or her deferred fees invested by a fund in
     shares of one or more funds in the John Hancock fund complex and the amount
     paid to the Trustees under the Plan will be determined based upon the
     performance of such investments. Deferral of Trustees' fees does not
     obligate the fund to retain the services of any Trustee or obligate the
     fund to pay any particular level of compensation to the Trustee.

Material Relationships of the Independent Trustees

     As of December 31, 2003, none of the Independent Trustees, nor any
immediate family member, owns shares of John Hancock Advisers, LLC (the
"investment adviser") or a principal underwriter of the Fund, nor does any such
person own shares of a company controlling, controlled by or under common
control with, the investment adviser or a principal underwriter of the fund.

     There have been no transactions by the fund since the beginning of the
fund's last two fiscal years, nor are there any transactions currently proposed,
in which the amount exceeds $60,000, and in which any trustee of the fund or any
immediate family members has or will have a direct or indirect material
interest, nor have any of the foregoing persons been indebted to the fund in an
amount in excess of $60,000 at any time since that date.

     No Independent Trustee, nor any immediate family member has had, in the
past five years, any direct or indirect interest, the value of which exceeds
$60,000, in the investment adviser, a principal underwriter of the fund or in a
person (other than a registered investment company) directly or indirectly
controlling, controlled by


                                       11


or under common control with, the investment adviser or principal underwriter of
the fund. Moreover, no Independent Trustee or immediate family member has, or
has had in the last two fiscal years of the fund, any direct or indirect
relationships or material interest in any transaction or in any currently
proposed transaction, in which the amount involved exceeds $60,000, in which the
following persons were or are a party: the fund, an officer of the fund, any
investment company sharing the same investment adviser or principal underwriter
as the fund or any officer of such a company, any investment adviser or
principal underwriter of the fund or any officer of such a party, any person
directly or indirectly controlling, controlled by or under common control with,
the investment adviser or principal underwriter of the fund, or any officer of
such a person.

     Within the last two completed fiscal years of the fund, no officer of any
investment adviser or principal underwriter of the fund or of any person
directly or indirectly controlling, controlled by or under common control with,
the investment adviser or principal underwriter of the fund, has served as a
director on a board of a company where any of the Independent Trustees or
nominees of the fund, or immediate family members of such persons, has served as
an officer.

Legal Proceedings

     There are no material pending legal proceedings to which any trustee or
affiliated person is a party adverse to the fund or any of its affiliated
persons or has a material interest adverse to the fund or any of its affiliated
persons. In addition, there have been no legal proceedings that are material to
an evaluation of the ability or integrity of any trustee or executive officer of
the fund within the past five years.

                                   PROPOSAL 2

                          RATIFICATION OF SELECTION OF
                       THE INDEPENDENT PUBLIC ACCOUNTANTS

     The Trustees, including a majority of the Independent Trustees, have
selected Deloitte & Touche LLP ("Deloitte & Touche") to act as independent
public accountants for the fund's fiscal year ending October 31, 2004.

     The following table sets forth the aggregate fees billed by the independent
accountants for the fund's 2003 and 2002 fiscal years for professional services
rendered for: (i) the audit of the fund's annual financial statements and the
review of financial statements included in the fund's reports to stockholders;
(ii) assurance and related services that are reasonably related to the audit of
the Fund's financial statements, (iii) tax compliance, tax advice or tax
planning and (iv) all services other than (i), (ii) and (iii). The table also
discloses the aggregate fees paid during the 2002 and 2003 fiscal years to the
Funds, independent accountants by John Hancock Advisers, LLC and any entity
controlling, controlled by or under common control with John Hancock Advisers,
LLC to the extent that the engagement relates directly to the operations and
financial reporting of registered investment companies (the "Adviser and Adviser
Affiliates").



                                                               Audit-related                      All other

                                       12


     The Fund's Audit Committee has adopted procedures to pre-approve audit and
non-audit services for the Funds and the Adviser and Adviser Affiliates. These
procedures identify certain types of audit and non-audit services that are
anticipated to be provided by Deloitte & Touche during a calendar year and,
provided the services are within the scope and value standards set forth in the
procedures, pre-approve those engagements. The scope and value criteria are
reviewed annually. These procedures require both audit and non-audit sources to
be approved by the Audit Committee prior to Deloitte & Touche being engaged. In
recommending Deloitte & Touche as the Fund's independent accountants, the Audit
Committee has considered the compensation provided to Deloitte & Touche for
audit and non-audit services to the Adviser and Adviser Affiliates and has
determined that such compensation is not incompatible with maintaining Deloitte
& Touche's independence. The aggregate amount of non-audit fees paid by the
Fund, the Adviser and an Advisor Affiliate that provide services to the Fund
were $2,100 and $190,913 for the fiscal years ending October 31, 2002 and 2003.

     Deloitte & Touche has advised the fund that it has no direct or indirect
financial interest in the fund. This selection is subject to the approval by the
shareholders of the fund at the meeting. The enclosed proxy card provides space
for instructions directing the proxies named on the proxy card to vote for,
against, or abstain from, ratifying that selection. A representative of Deloitte
& Touche is expected to be present at the meeting, will have the opportunity to
make a statement if the representative desires to do so and will be available to
respond to appropriate questions relating to the examination of the fund's
financial statements.

     The Board of Trustees, including all the Independent Trustees, unanimously
recommends that shareholders ratify the selection of Deloitte & Touche as
independent public accountants of the fund for the fiscal year ending October
31, 2004.

Vote Required to Ratify the Selection of Independent Public Accountants

     The approval of a "majority" of the shares of the fund is required to
ratify the selection of Deloitte & Touche as such fund's independent public
accountants.

                                  MISCELLANEOUS

Voting; Quorum; Adjournment

     The following vote is required to approve each respective proposal:

Election of Trustees     A plurality of all votes cast, assuming a quorum exists.* A "plurality"
(Proposal 1)             means that the three nominees up for election receiving the greatest
                         number of votes will be elected as trustees, regardless of the number of
                         votes cast.

*    In order for a "quorum" to exist, a majority of the shares outstanding and
     entitled to vote must be present at the meeting, either in person or by
     proxy, determined in accordance with the table below.

     Proposals 1 and 2 in this proxy statement are considered routine matters
on which brokers holding shares in "street name" may vote without instruction
under the rules of the New York Stock Exchange.


                                       13


     The following table summarizes how the quorum and voting requirements are
determined.

                            by proxy are counted in               person by the shareholder at the meeting.
                            determining whether a quorum          Shares present by proxy will be voted by
                            exists.                               the proxyholder in accordance with
                                                                  instructions supplied in the proxy.

Broker Non-Vote             Considered "present" at meeting.      Not voted. Same effect as a vote "against"
                                                                  a proposal.

Proxy with No Voting        Considered "present" for              Will be voted "for" the proposal by the
Instruction (other than     determining whether a quorum          proxyholder.
Broker Non-Vote)            exists.

Vote to Abstain             Considered "present" for              Disregarded. Because abstentions are not

     If a quorum is not present, the persons named as proxies may vote their
proxies to adjourn the meeting to a later date. If a quorum is present, but
there are insufficient votes to approve any proposal, the persons named as
proxies may propose one or more adjournments of the meeting to permit further
solicitation. Shareholder action may be taken on one or more proposals prior to
such adjournment. Proxies instructing a vote for a proposal will be voted in
favor of an adjournment with respect to that proposal, and proxies instructing a
vote against a proposal will be voted against an adjournment with respect to
that proposal.

Expenses and Methods of Solicitation

     The costs of the meeting, including the solicitation of proxies, will be
paid by the fund. Persons holding shares as nominees will be reimbursed by the
fund, upon request, for their reasonable expenses in sending soliciting material
to the principals of the accounts. In addition to the solicitation of proxies by
mail, Trustees, officers and employees of the fund or of the fund's adviser may
solicit proxies in person or by telephone. John Hancock Advisers, LLC, 101
Huntington Avenue, Boston, Massachusetts 02199-7603, serves as the fund's
investment adviser and administrator. Mellon Investors Services LLC has been
retained to assist in the solicitation of proxies at a cost of approximately
$5,000, plus reasonable expenses.


Telephone Voting

     In addition to soliciting proxies by mail, by fax or in person, the fund
may also arrange to have votes recorded by telephone by officers and employees
of the fund or by the personnel of the adviser or the transfer agent or
solicitor. The telephone voting procedure is designed to verify a shareholder's
identity, to allow a shareholder to authorize the voting of shares in accordance
with the shareholder's instructions and to confirm that the voting instructions
have been properly recorded. If these procedures were subject to a successful
legal challenge, the telephone votes would not be counted at the meeting. The
fund has not obtained an opinion of counsel about telephone voting, but is
currently not aware of any challenge.

     o   A shareholder will be called on a recorded line at the telephone number
         in the fund's account records and will be asked to provide the
         shareholder's social security number or other identifying information.


                                       14


     o   The shareholder will then be given an opportunity to authorize proxies
         to vote his or her shares at the meeting in accordance with the
         shareholder's instructions.

     o   To ensure that the shareholder's instructions have been recorded
         correctly, the shareholder will also receive a confirmation of the
         voting instructions by mail.

     o   A toll-free number will be available in case the voting information
         contained in the confirmation is incorrect.

     o   If the shareholder decides after voting by telephone to attend the
         meeting, the shareholder can revoke the proxy at that time and vote the
         shares at the meeting.

Other Matters

     The management of the fund knows of no business to be brought before the
meeting except as mentioned above. If, however, any other matters were properly
to come before the meeting, the persons named on the enclosed proxy card intend
to vote on those matters in accordance with their best judgment. If any
shareholders desire additional information about the matters proposed for
action, the management will provide further information.

                              SHAREHOLDER PROPOSALS

     Shareholder proposals intended to be presented at a fund's annual meeting
in 2005 must be received by the fund at its offices at 101 Huntington Avenue,
Boston, Massachusetts, after September 30, 2004, but no later than October 29,
2004, for inclusion in that fund's proxy statement and form of proxy relating to
that meeting (subject to certain exceptions).

JOHN HANCOCK BANK AND THRIFT OPPORTUNITY FUND

Dated: January 30, 2004


                                       15


                                    EXHIBIT A

                               JOHN HANCOCK FUNDS
                             AUDIT COMMITTEE CHARTER

     A. Composition. The Audit Committee shall be composed exclusively of
Independent Trustees who are designated for membership from time to time by the
Administration Committee. The Audit Committee shall be composed of at least
three Independent Trustees who are free of any relationship that, in the opinion
of the Administration Committee, may interfere with such member's individual
exercise of independent judgment and are otherwise independent under any
applicable rule or listing requirement. Each Audit Committee member shall also
meet the independence and financial literacy requirements for serving on audit
committees, and at least one member shall have accounting or related financial
management expertise, all as set forth in applicable rules or listing
requirements.

     B. Overview. The Audit Committee's job is one of oversight. The Audit
Committee shall discharge its responsibilities, and shall access the information
provided by the funds' management and independent auditors, in accordance with
its business judgment. Management is responsible for the preparation of the
fund's financial statements and the independent auditors are responsible for
auditing those financial statements. The Audit Committee and the Board of
Trustees recognize that management (including the internal audit staff) and the
independent auditors have more experience, expertise, resources and time, and
more detailed knowledge and information regarding a fund's accounting, auditing,
internal control and financial reporting practices than the Audit Committee
does. Accordingly, the Audit Committee's oversight role does not provide any
expert or special assurance as to the financial statements and other financial
information provided by a fund to its shareholders and others. The independent
auditors are responsible for auditing the Company's financial statements and for
reviewing the Company's unaudited interim financial statements. The authority
and responsibilities set forth in this Charter do not reflect or create any duty
or obligation of the Audit Committee to plan or conduct any audit, to determine
or certify that any fund's financial statements are complete, accurate, fairly
presented, or in accordance with generally accepted accounting principles or
applicable law, or to guarantee any independent auditor's report.

     C. Oversight. The independent auditors shall report directly to the Audit
Committee, and the Audit Committee shall be directly responsible for oversight
of the work of the independent auditors, including resolution of disagreements
between any fund's management and the independent auditors regarding financial
reporting.

     D. Specific Responsibilities. The Audit Committee shall have the following
duties and powers, to be exercised at such times and in such manner as the
Committee shall deem necessary or appropriate:

     1.  To oversee the funds' auditing and accounting process.

     2.  To approve, and recommend to the full Board of Trustees for its
         ratification and approval in accord with applicable law, the selection
         and appointment of an independent auditor for each fund prior to the
         engagement of such independent auditor.

     3.  To pre-approve all audit and non-audit services provided to each fund
         by its independent auditor, directly or by establishing pre-approval
         policies and procedures pursuant to which such services may be
         rendered, provided however, that any such policies and procedures are
         detailed as to particular services, the Audit Committee is informed of
         each service, and any such policies and procedures do not include the
         delegation of the Audit Committee's responsibilities under the
         Securities Exchange Act of 1934 or applicable rules or listing
         requirements.


                                       16


     4.  To pre-approve all non-audit services provided by a Fund's independent
         auditor to the Fund's investment adviser and any entity controlling,
         controlled by, or under common control with the investment adviser that
         provides ongoing services to the Fund, if the engagement relates
         directly to the operations and financial reporting of the Fund.

     5.  To monitor the independent auditor of each fund throughout the
         engagement to attempt to identify: conflicts of interest between
         management and the independent auditor as a result of employment
         relationships; the provision of prohibited non-audit services to a fund
         by its independent auditor; violations of audit partner rotation
         requirements; and prohibited independent auditor compensation
         arrangements whereby individuals employed by the auditor are
         compensated based on selling non-audit services to the fund.

     6.  To meet with independent auditors, management's internal auditors, and

           the reporting attorney reasonably believes that it would be futile to

               necessary;

     and, at the conclusion of such investigation, to:

          (A)  recommend, by majority vote, that the Fund implement an
               appropriate response to evidence of a material violation; and

          (B)  inform the CLO and the CEO and the Board of Trustees of the
               results of any such investigation and the appropriate remedial
               measures.

     (iii) by majority vote, to take all other appropriate action, including
           notifying the U.S. Securities and Exchange Commission in the event
           that the Fund fails in any material respect to implement an
           appropriate response that the QLCC has recommended.
