Dear Shareholder:
 
       We are proud to bring you the 2004 annual report for the CALAMOS
Convertible and High Income Fund (CHY) covering the fiscal year ended October
31, 2004.
       For those of you who are new to CHY or to CALAMOS Investments this year,
we welcome you as an investor. For those of you who have included CHY in your
portfolio for an extended period, I thank you for your continued confidence in
our investment products. In CHY, as in all of our funds, we strive to maintain
an appropriate balance between risk and reward that seeks to provide you with
outstanding long-term performance.
       Investing in a diversified portfolio of convertible securities and high
yield bonds, CHY seeks total return through a combination of capital
appreciation and current income. We have continued to focus on a selection of
names that have the potential to appreciate due to credit-quality upgrades, or
ongoing merger and acquisition activity. Believing that the economy is in the
middle part of the economic cycle, the portfolio is focused on companies that we
believe can grow steadily. We are generally avoiding the lowest quality bonds in
favor of higher-rated securities, and steering clear of interest-rate sensitive
convertibles, preferring those with more equity-like characteristics. To help
offset some of the effects of raising short-term interest rates on the Fund's
yield, the Fund has continued to maintain interest-rate swap positions in
connection with its leverage.
       Moreover, the Fund paid a consistent dividend throughout the fiscal year.
Remember that you can use these distributions to your advantage by reinvesting
them through the Fund's dividend reinvestment plan and accumulate additional
shares of the Fund. Through this plan, when the Fund's market price is at a
discount to NAV, your distributions are used to purchase shares at this lower
price, and even when the Fund is at premium to its NAV, your dividends
automatically purchase shares at NAV or 95% of the market price, whichever is
greater.
       At CALAMOS Investments, we remain committed to helping you achieve your
long-term financial goals. Thank you for choosing the CALAMOS Convertible and
High Income Fund.
 
                                                    Sincerely,
 
                                                    /s/ John P. Calamos

   PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. You can purchase or sell
   common shares daily. Like any other stock, market price will fluctuate with
   the market. Upon sale, your shares may have a market price that is above or
   below net asset value and may be worth more or less than your original
   investment. Due to ongoing market volatility, performance is subject to
   substantial short-term fluctuations.
 
   +  Total return measures net investment income and capital gain or loss from
      portfolio investments, assuming reinvestment of income and capital gains
      distributions.

NOTES TO SCHEDULE OF INVESTMENTS
 
Note: Market values for securities denominated in foreign currencies are shown
in U.S. dollars.
 
(a) 144A securities are those that are exempt from registration under Rule 144A
    of the Securities Act of 1933, as amended. These securities are generally
    issued to qualified institutional buyers ("QIBs"), such as the Fund. Any
    resale of these securities must generally be effected through a sale that is
    exempt from registration (e.g., a sale to another QIB), or the security must
    be registered for public sale. At October 31, 2004, the market value of 144A
    securities that cannot currently be exchanged to the registered form is
    $149,258,334 or 15.8% of net assets applicable to common shareholders of the
    Fund.
(b) Non-income producing security.
(c) Security, or portion of security, is on loan.
(d) Security is purchased with the cash collateral from securities loaned.

                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1 - ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
ORGANIZATION.  CALAMOS Convertible and High Income Fund (the "Fund") was
organized as a Delaware statutory trust on March 12, 2003 and is registered
under the Investment Company Act of 1940 as a diversified, closed-end management
investment company. The Fund commenced operations on May 30, 2003.
 
The Fund's investment objective is to provide total return, through a
combination of capital appreciation and current income. The Fund currently seeks
to achieve its investment objective by investing in a diversified portfolio of
convertible securities and high yield bonds.
 
PORTFOLIO VALUATION.  In computing the net asset value of the Fund, portfolio
securities, including options, that are traded on a national securities exchange
are valued at the last reported sales price. Securities quoted on the NASDAQ
National Market System are valued at the Nasdaq Official Closing Price ("NOCP"),
as determined by Nasdaq, or lacking an NOCP, the last current reported sale
price as of the time of valuation. Securities traded in the over-the counter
market and listed securities for which no sales were reported are valued at the
mean of the most recently quoted bid and asked prices. Short-term securities
with maturities of 60 days or less are valued at amortized cost, which
approximates market value.
 
When market quotations are not readily available or when the valuation methods
mentioned above are not reflective of the fair value of the security, the
security is valued at a fair value following procedures or guidelines approved
by the Board of Trustees or a committee approved by the Board of Trustees. The
Fund may also use fair value pricing, if the value of a security it holds is, in
the opinion of the valuation committee or pursuant to Board of Trustees'
guidelines, may be significantly affected by events occurring after the close of
the primary market or exchange on which the security is traded. These procedures
may utilize valuations furnished by pricing services approved by the Board of
Trustees or a committee thereof, which may be based on market transactions for
comparable securities and various relationships between securities that are
generally recognized by institutional traders, a computerized matrix system, or
appraisals derived from information concerning the securities or similar
securities received from recognized dealers in those securities. When fair value
pricing is employed, the value of the portfolio security used to calculate the
Fund's net asset value may differ from quoted or published prices.
 
Securities that are principally traded in a foreign market are valued as of the
close of the appropriate exchange or other designated time. Trading in
securities on European and Far Eastern securities exchanges and over-the-counter
markets is normally completed at various times before the close of business on
each day on which the New York Stock Exchange ("NYSE") is open. Trading of these
securities may not take place on every NYSE business day. In addition, trading
may take place in various foreign markets on Saturdays or on other days when the
NYSE is not open and on which the Fund's net asset value is not calculated. As
stated above, if the market prices are not readily available or are not
reflective of the fair value of the security, the security will be valued at a
fair value following procedures approved by the Board of Trustees or a committee
approved by the Board of Trustees.
 
INVESTMENT TRANSACTIONS AND INVESTMENT INCOME.  Short term investment
transactions are recorded on a trade date basis. Long term investment
transactions are recorded on a trade date plus one basis, except for fiscal
quarter ends, which are recorded on trade date. Net realized gains and losses
from investment transactions are reported on an identified cost basis. Interest
income is recognized using the accrual method and includes accretion of original
issue and market discount and amortization of premium. Dividend income is
recognized on the ex-dividend date, except that certain dividends from foreign
securities are recorded as soon as the information becomes available.
 
FOREIGN CURRENCY TRANSLATION.  Values of investments and other assets and
liabilities denominated in foreign currencies are translated into U.S. dollars
using the spot market rate of exchange at the date of valuation. Purchases and
sales of investments and dividend and interest income are translated into U.S.
dollars using the spot market rate of exchange prevailing on the respective
dates of such transaction.
 
                                                                              15

                         NOTES TO FINANCIAL STATEMENTS
 
The Fund does not isolate that portion of the results of operations resulting
from changes in foreign exchange rates on investments from the fluctuations
arising from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.
 
Reported net realized foreign currency gains or losses arise from disposition of
foreign currency, currency gains or losses realized between the trade and
settlement dates on securities transactions, and the difference between the
amounts of dividends, interest and foreign withholding taxes recorded on the
Fund's books on the transaction date and the U.S. dollar equivalent of the
amounts actually received or paid. Net unrealized foreign exchange gains and
losses arise from changes (due to the changes in the exchange rate) in the value
of foreign currency and other assets and liabilities denominated in foreign
currencies held at period end.
 
OPTION TRANSACTIONS.  For hedging and investment purposes, the Fund may purchase
or write (sell) put and call options. One of the risks associated with
purchasing an option among others, is that the Fund pays a premium whether or
not the option is exercised. Additionally, the Fund bears the risk of loss of
premium and change in market value should the counterparty not perform under the
contract. Put and call options purchased are accounted for in the same manner as
portfolio securities. The cost of securities acquired through the exercise of
call options is increased by premiums paid. The proceeds from securities sold
through the exercise of put options are decreased by the premiums paid.
 
When the Fund writes an option, an amount equal to the premium received by the
Fund is recorded as a liability and is subsequently adjusted to the current
value of the option written. Premiums received from writing options that expire
unexercised are treated by the Fund on the expiration date as realized gains
from investments. The difference between the premium and the amount paid on
effecting a closing purchase transaction, including brokerage commissions, is
also treated as a realized gain, or, if the premium is less than the amount paid
for the closing purchase transaction, as a realized loss. If a call option is
exercised, the premium is added to the proceeds from the sale of the underlying
security or currency in determining whether the Fund has realized a gain or
loss. If a put option is exercised, the premium reduces the cost basis of the
securities purchased by the Fund. The Fund, as writer of an option, bears the
market risk of an unfavorable change in the price of the security underlying the
written option. During the year ended October 31, 2004, the Fund did not write
any options.
 
USE OF ESTIMATES.  The preparation of financial statements in conformity with
accounting principles generally accepted in the United States requires
management to make estimates and assumptions that affect the amounts reported in

those estimates.
 
NOTE 2 - INVESTMENT ADVISER AND TRANSACTIONS WITH AFFILIATES OR CERTAIN OTHER
PARTIES
 
Pursuant to an investment advisory agreement with Calamos Advisors LLC ("Calamos
Advisors"), the Fund pays an annual fee, payable monthly, equal to 0.80% based
on the average weekly managed assets. "Managed Assets" means the total assets of
the Fund (including any assets attributable to any leverage that may be
outstanding) minus the sum of total liabilities (other than debt representing
financial leverage). Calamos Advisors has contractually agreed to waive a
portion of its management fee at the annual rate of 0.10% of the average weekly
managed assets of the Fund for the first five full years of the Fund's operation
(through May 31, 2008) and to waive a declining amount for an additional three
years (0.07% of the average weekly managed assets in 2009, 0.05% in 2010, and
0.03% in 2011).
 
Calamos Advisors receives a fee payable monthly at the annual rate of 0.0175% on
the first $1 billion of combined assets; 0.0150% on the next $1 billion of
combined assets; and 0.0110% on combined assets above $2 billion for financial
accounting services (for purposes of this calculation combined assets means the
managed assets of Calamos Investment Trust, Calamos Advisors Trust, Calamos
Convertible and High Income Fund and Calamos Strategic Total Return Fund).
Effective November 1, 2004 the managed assets of Calamos Convertible
Opportunities and Income Fund will be included in combined assets. Financial
accounting services include, but are not limited to, the following: managing
expenses and expense payment processing; monitoring the calculation of expense
accrual amounts; calculating, tracking, and reporting tax adjustments on all
 16

                         NOTES TO FINANCIAL STATEMENTS
 
assets and monitoring trustee deferred compensation plan accruals and
valuations. The Funds will pay their pro rata share of the financial accounting
service fee payable to CALAMOS Advisors based on relative assets of each Fund.
 
As of November 1, 2004, State Street Bank & Trust Company ("SSB&T") will act as
the Fund Accounting Agent/Administrator for the Fund. The Fund will pay SSB&T a
fee payable monthly at the annual rate of 0.0175% on the first $1.5 billion of
the combined assets of the Calamos Convertible Opportunities and Income Fund,
Calamos Convertible and High Income Fund and Calamos Strategic Total Return
Fund; 0.0150% of the next $1.5 billion of combined assets (combined assets in
excess of $1.5 billion to $3 billion), 0.0125% of the next $1.5 billion of
combined assets (combined assets in excess of $3 billion to $4.5 billion),
0.0100% of the next $1.5 billion of combined assets (combined assets in excess
of $4.5 billion to $6 billion), 0.0075% of the next $1.5 billion of combined
assets (combined assets in excess of $6 billion to $7.5 billion) and 0.00375% of
combined assets in excess of $7.5 billion.
 
Certain officers and trustees of the Fund are also officers and directors of CFS
and Calamos Advisors. All officers and affiliated trustees serve without direct
compensation from the Fund. The Fund has adopted a deferred compensation plan
(the "Plan"). Under the Plan, a Trustee who is not an "interested person" of
Calamos Advisors and has elected to participate in the Plan (a "participating
trustee") may defer receipt of all or a portion of his compensation from the
Fund. The deferred compensation payable to the participating trustee is credited
to the trustee's deferral account as of the business day such compensation would
have been paid to the trustee. The value of a trustee's deferred compensation
account at any time is equal to what would be the value if the amounts credited
to the account had instead been invested in shares of one or more of the funds
of the Calamos Investment Trust as designated by the trustee. Thus, the value of
the account increases with contributions to the account or with increases in the
value of the measuring shares, and the value of the account decreases with
withdrawals from the account or with declines in the value of the measuring
shares. If a participating trustee retires, the trustee may elect to receive
payments under the plan in a lump sum or in equal installments over a period of
five years. If a participating trustee dies, any amount payable under the Plan
will be paid to the trustee's beneficiaries. Deferred compensation investments
of $7,134 are included in "Other Assets" on the Statement of Assets and
Liabilities at October 31, 2004. The Fund's obligation to make payments under
the Plan is a general obligation of the Fund.

NOTE 4 - INCOME TAXES
 
No provision has been made for income taxes because the Fund's policy is to
qualify as a regulated investment company under Subchapter M of the Internal
Revenue Code and distribute to shareholders substantially all of its taxable
income and gains.
 
Dividends and distributions paid to shareholders are recorded on the ex-dividend
date. The amount of dividends and distributions from net investment income and
net realized capital gains is determined in accordance with Federal income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. To the extent
                                                                              17

                         NOTES TO FINANCIAL STATEMENTS
 
these "book/tax" differences are permanent in nature, such amounts are
reclassified within the capital accounts based on their Federal tax-basis
treatment. These differences are primarily due to differing treatments for
foreign currency transactions, contingent payment debt instruments and methods
of amortizing and accreting on fixed income securities. Financial records are
not adjusted for temporary differences.
 
For the year ended October 31, 2004, the Fund recorded the following permanent
reclassifications to reflect tax character. Results of operations and net assets
were not affected by these reclassifications.

Accumulated net realized gain (loss) on investments and
  foreign currency transactions and interest rate swaps           6,413,024

 
As of October 31, 2004, the components of net assets on a tax basis were as
follows:

For the tax year ended October 31, 2004, the Fund utilized capital losses of
$339,098. As of October 31, 2004, the Fund had capital loss carryforwards of
$5,148,747 which, if not used, will expire in 2011.
 
NOTE 5 - COMMON STOCK
 
There are unlimited common shares of beneficial interest authorized and
61,091,942 shares outstanding at October 31, 2004. Calamos Advisors LLC owned

* The Fund commenced operations on May 30, 2003.
 
NOTE 6 - FORWARD FOREIGN CURRENCY CONTRACTS
 
The Fund may engage in portfolio hedging with respect to changes in currency
exchange rates by entering into forward foreign currency contracts to purchase
or sell currencies. A forward foreign currency contract is a commitment to
purchase or sell a foreign currency at a future date at a negotiated forward
rate. Risks associated with such contracts include movement in the value of the
foreign currency relative to the U.S. dollar and the ability of the counterparty
to perform. The net unrealized gain, if any, represents the credit risk to the
Fund on a forward foreign currency contract. The contracts are valued daily at
 18

                         NOTES TO FINANCIAL STATEMENTS
 
forward exchange rates, and an unrealized gain or loss is recorded. The Fund
realizes a gain or loss upon settlement of the contracts. There were no open
forward foreign currency contracts at October 31, 2004.
 
NOTE 7 - SYNTHETIC CONVERTIBLE SECURITIES
 
The Fund may create a "synthetic" convertible security by combining separate
securities that possess the two principal characteristics of a true convertible
security, i.e., fixed-income securities ("fixed-income component") and the right
to acquire equity securities ("convertible component"). The fixed-income
component is achieved by investing in non-convertible, fixed-income securities
such as bonds, preferred stocks and money market instruments. The convertible
component is achieved by investing in warrants or options to buy common stock at
a certain exercise price, or options on a stock index. In creating a synthetic
security, the Fund may also pool a basket of fixed-income securities and a
basket of warrants or options that produce the economic characteristics similar
to a convertible security. Within each basket of fixed-income securities and
warrants or options, different companies may issue the fixed-income and
convertible components, which may be purchased separately and at different
times.
 
The Fund may purchase synthetic securities created by other parties, typically
investment banks, including convertible structured notes. Convertible structured
notes are fixed-income debentures linked to equity. Convertible structured notes
have the attributes of a convertible security; however, the investment bank that
issued the convertible note assumes the credit risk associated with the
investment, rather than the issuer of the underlying common stock into which the
note is convertible. Purchasing synthetic convertible securities may offer more
flexibility than purchasing a convertible security. Different companies may
issue the fixed-income and convertible components, which may be purchased
separately and at different times.
 
NOTE 8 - PREFERRED SHARES
 
There are unlimited shares of Auction Rate Cumulative Preferred Shares
("Preferred Shares") authorized. The Preferred Shares have rights as determined
by the Board of Trustees. The 17,200 shares of Preferred Shares outstanding
consist of six series, 3,000 shares of M, 3,000 shares of TU, 3,000 shares of W,
3,000 shares of TH, 3,000 shares of F and 2,200 shares of A. The Preferred
Shares have a liquidation value of $25,000 per share plus any accumulated but
unpaid dividends whether or not declared.
 
Dividends on the Preferred Shares are cumulative at a rate typically reset every
seven and twenty-eight days based on the results of an auction. Dividend rates
ranged from 1.25% to 2.34% for the year ended October 31, 2004. Under the
Investment Company Act of 1940, the Fund may not declare dividends or make other
distributions on shares of common stock or purchase any such shares if, at the
time of the declaration, distribution or purchase, asset coverage with respect
to the outstanding Preferred Shares would be less than 200%.
 
The Preferred Shares are redeemable at the option of the Fund, in whole or in
part, on any dividend payment date at $25,000 per share plus any accumulated but
unpaid dividends. The Preferred Shares are also subject to mandatory redemption
at $25,000 per share plus any accumulated but unpaid dividends, whether or not
declared, if certain requirements relating to the composition of the assets and
liabilities of the Fund as set forth in the Statement of Preferences are not
satisfied.
 
The holders of Preferred Shares have voting rights equal to the holders of
common stock (one vote per share) and will vote together with holders of shares
of common stock as a single class except on matters affecting only the holders
of Preferred Shares or the holders of common shares.
 
NOTE 9 - INTEREST RATE TRANSACTIONS
 
The Fund may enter into interest rate swap or cap transactions to attempt to
protect itself from increasing dividend or interest expense on its leverage
resulting from increasing short-term interest rates. A decline in interest rates
may result in a decline in the value of the swap or cap, which may result in a
decline in the net asset value of the Fund. In addition, if the counterparty to
an interest rate swap or cap defaults, the Fund would not be able to use the
anticipated receipts under the swap or cap to offset the dividend or interest
payments on the Fund's leverage. At the time an interest rate swap or cap
                                                                              19

                         NOTES TO FINANCIAL STATEMENTS
 
reaches its scheduled termination, there is a risk that the Fund would not be
able to obtain a replacement transaction or that the terms of the replacement
would not be as favorable as on the expiring transaction. In addition, if the
Fund is required to terminate any swap or cap early due to the Fund failing to
maintain a required 200% asset coverage of the liquidation value of the
outstanding Preferred Shares or the Fund loses its credit rating on its
Preferred Shares, then the Fund could be required to make a termination payment,
in addition to redeeming all or some of the Preferred Shares. Details of the
swap agreements outstanding as of October 31, 2004 were as follows:
 


                                                                                                                     UNREALIZED

NOTE 10 - SECURITIES LENDING
 
During the year ended October 31, 2004, the Fund lent certain of its securities
to broker-dealers and banks. Any such loan must be continuously secured by
collateral in cash or cash equivalents maintained on a current basis in an
amount at least equal to the market value of the securities loaned by the Fund.
The Fund would continue to receive the equivalent of the interest or dividends
paid by the issuer on the securities loaned and would also receive an additional
return that may be in the form of a fixed fee or a percentage of the collateral.
The Fund may pay reasonable fees to persons unaffiliated with the Fund for
services in arranging these loans. The Fund would have the right to call the
loan and obtain the securities loaned at any time on notice of not more than
five business days. The Fund would not have the right to vote the securities
during the existence of the loan but could call the loan in an attempt to permit
voting of the securities in certain circumstances. Upon return of the securities
loaned, the cash or cash equivalent collateral will be returned to the borrower.
In the event of bankruptcy or other default of the borrower, the Fund could
experience both delays in liquidating the loan collateral or recovering the
loaned securities and losses, including (a) possible decline in the value of the
collateral or in the value of the securities loaned during the period while the
Fund seeks to enforce its rights thereto, (b) possible subnormal levels of
income and lack of access to income during this period, and (c) expenses of
enforcing its rights. In an effort to reduce these risks, the investment manager
and security lending agent will monitor the creditworthiness of the firms to
which the Fund lends securities. At October 31, 2004, the Fund had securities
valued at $266,168,171 that were on loan to broker-dealers and banks and
$271,744,233 in cash or cash equivalent collateral. The collateral represented
cash equivalents of $1,926,600, which may be sold or pledged only upon default
of the borrower.

                             PUBLIC ACCOUNTING FIRM
 
To the Board of Trustees and Shareholders of
CALAMOS Convertible and High Income Fund
 
We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of CALAMOS Convertible and High Income Fund (the
"Fund") as of October 31, 2004, and the related statement of operations for the
year then ended, and the statements of changes in net assets and the financial
highlights for the year then ended and for the period from May 30, 2003
(commencement of operations) through October 31, 2003. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.
 
We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004, by correspondence with the Fund's
custodian and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provides a reasonable basis for our opinion.
 
In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
Fund as of October 31, 2004, and the results of its operations for the year then
ended, and the changes in its net assets and the financial highlights for the
year then ended and for the period from May 30, 2003 (commencement of
operations) through October 31, 2003, in conformity with accounting principles
generally accepted in the United States of America.

ITEM 2.  CODE OF ETHICS.

(a) The registrant has adopted a code of ethics (the "Code of Ethics") that
applies to its principal executive officer, principal financial officer,
principal accounting officer or controller, or person performing similar
functions.

(b) Not applicable.

(c) The registrant has not amended its Code of Ethics during the period covered
by the shareholder report presented in Item 1 hereto.

(d) The registrant has not granted a waiver or an implicit waiver from its Code
of Ethics during the period covered by the shareholder report presented in Item

ITEM 3.  AUDIT COMMITTEE FINANCIAL EXPERT.

The registrant's Board of Trustees has determined that, for the period covered
by the shareholder report presented in Item 1 hereto, it has two audit committee
financial experts serving on its audit committee, each of whom is an independent
Trustee for purpose of this N-CSR item: John E. Neal and William Rybak. Under
applicable securities laws, a person who is determined to be an audit committee
financial expert will not be deemed an "expert" for any purpose, including
without limitation for the purposes of Section 11 of the Securities Act of 1933,
as a result of being designated or identified as an audit committee financial
expert. The designation or identification of a person as an audit committee
financial expert does not impose on such person any duties, obligation, or
liabilities that are greater than the duties, obligations and liabilities
imposed on such person as a member of audit committee and Board of Trustees in
the absence of such designation or identification.


ITEM 4.  PRINCIPAL ACCOUNTANT FEES AND SERVICES.

connection with statutory and regulatory filings or engagements for those fiscal
years.

(b) Audit-Related Fees - $17,500 and $17,917 are the aggregate fees billed in

reported under paragraph (a) of this Item 4.

(c) Tax Fees - $13,675 and $6,079 are the aggregate fees billed in each of the

tax return preparation.

    There were no fees billed in each of the last two fiscal years for
professional services rendered by the principal accountant to the investment
adviser for tax compliance, tax advice and tax planning that were required to be
pre-approved by the audit committee as described in paragraph (e)(1) of this
Item 4.

(d) All Other Fees - $5,250 and $7,500 are the aggregate fees billed in each of
the last two fiscal years for products and services provided by the principal

(e) (1) Registrant's audit committee meets with the principal accountants and
management to review and pre-approve all audit services to be provided by the
principal accountants.

    The audit committee shall pre-approve all non-audit services to be provided
by the principal accountants to the registrant, including the fees and other
compensation to be paid to the principal accountants; provided that the
pre-approval of non-audit services is waived if (i) the services were not
recognized by management at the time of the engagement as non-audit services,
(ii) the aggregate fees for all non-audit services provided to the registrant
are less than 5% of the total fees paid by the registrant to its principal
accountants during the fiscal year in which the non-audit services are provided,
and (iii) such services are promptly brought to the attention of the audit
committee by management and the audit committee approves them prior to the
completion of the audit.


    The audit committee shall pre-approve all non-audit services to be provided
by the principal accountants to the investment adviser or any entity
controlling, controlled by or under common control with the adviser that
provides ongoing services to the registrant if the engagement relates directly
to the operations or financial reporting of the registrant, including the fees
and other compensation to be paid to the principal accountants; provided that
pre-approval of non-audit services to the adviser or an affiliate of the adviser
is not required if (i) the services were not recognized by management at the
time of the engagement as non-audit services, (ii) the aggregate fees for all
non-audit services provided to the adviser and all entities controlling,
controlled by or under common control with the adviser are less than 5% of the
total fees for non-audit services requiring pre-approval under paragraph (e)(1)
of this Item 4 paid by the registrant, the adviser or its affiliates to the
registrant's principal accountants during the fiscal year in which the non-audit
services are provided, and (iii) such services are promptly brought to the
attention of the audit committee by management and the audit committee approves
them prior to the completion of the audit.

    (2) 100% of the services provided to the registrant described in paragraphs
(b)-(d) of this Item 4 were pre-approved by the audit committee pursuant to
paragraphs (e)(1) of this Item 4. There were no services provided to the
investment adviser or any entity controlling, controlled by or under common
control with the adviser described in paragraphs (b)-(d) of this Item 4 that
were required pre-approved by the audit committee.

(f) No disclosures are required by this Item 4(f).

of the last two fiscal years for services rendered by the principal accountant
to the investment adviser or any entity controlling, controlled by or under
common control with the adviser. All of the aggregate fees billed by the
principal accountant for non-audit services to the registrant's investment
adviser relate to services that began prior to the adoption of rules requiring
audit committee pre-approval. However, the registrant's audit committee did
approve such non-audit services.

(h) No disclosures are required by this Item 4(h).
