*    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 July 31, 2006, the market value of
     144A securities that were not subject to mandatory issuer registration

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 (the "1940 Act") as a diversified,
closed-end management investment company. The Fund commenced operations on May
28, 2003.

The Fund's investment objective is to provide total return through a combination
of capital appreciation and current income. Under normal circumstances, the Fund
will invest at least 80% of its managed assets in a diversified portfolio of
convertible and non-convertible income securities. "Managed assets" means the
Fund's total assets (including any assets attributable to any leverage that may
be outstanding) minus total liabilities (other than debt representing financial
leverage).

PORTFOLIO VALUATION. Calamos Advisors LLC values the Fund's portfolio securities
in accordance with policies and procedures on the valuation of securities
adopted by the Board of Trustees and under the ultimate supervision of the Board
of Trustees.

Portfolio securities that are traded on U.S. securities exchanges, except option
securities, are valued at the last current reported sales price at the time as
of which the Fund determines its NAV. Securities traded in the over-the-counter
("OTC") market and quoted on The Nasdaq Stock Market are valued at the Nasdaq
Official Closing Price ("NOCP"), as determined by Nasdaq, or lacking a NOCP, the
last current reported sale price on Nasdaq at the time as of which the Fund
determines its NAV.

When a most recent last sale or closing price is not available, portfolio
securities, other than option securities, that are traded on a U.S. securities
exchange and other securities traded in the OTC market are valued at the mean
between the most recent bid and asked quotations in accordance with guidelines
adopted by the Board of Trustees. Each option security traded on a U.S.
securities exchange is valued at the mid-point of the consolidated bid/ask quote
for the option security, also in accordance with guidelines adopted by the Board
of Trustees. Each OTC option that is not traded through the Options Clearing
Corporation is valued by the counterparty to such option. If the pricing
committee determines that the valuation of a security in accordance with the
methods described above is not reflective of a fair value for such security, the
security, including any thinly-traded security, junk bond or synthetic
convertible instrument, is valued at a fair value by the pricing committee,
under the ultimate supervision of the Board of Trustees, following the
guidelines and/or procedures adopted by the Board of Trustees, which may include
utilizing a systematic fair valuation model provided by an independent pricing
service.

Securities that are principally traded in a foreign market are valued as of the
last current sale price at the time as of which the Fund determines its NAV, or
when reliable market prices or quotations are not readily available, at the mean
between the most recent bid and asked quotations as of the close of the
appropriate exchange or other designated time,


10



                        NOTES TO SCHEDULES OF INVESTMENTS
                                   (unaudited)

in accordance with guidelines adopted by the Board of Trustees. Trading in
securities on European and Far Eastern securities exchanges and OTC markets is
normally completed at various times before the close of business on each day on
which the 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 NAV is not calculated. As stated above, if the market prices are not
readily available or are not reflective of a security's fair value, the security
is valued at a fair value by the pricing committee, under the ultimate
supervision of the Board of Trustees, following the guidelines and/or procedures
adopted by the Board of Trustees.

The Fund also may use fair value pricing, pursuant to Board of Trustees
guidelines and under the ultimate supervision of the Board of Trustees if the
value of a foreign security it holds is materially affected by events occurring
before their pricing time but after the close of the primary market or exchange
on which the security is traded. Those procedures may utilize valuations
furnished by pricing services approved by the Board of Trustees, 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 of securities is employed, the prices of securities used
by the Fund to calculate its NAV may differ from market quotations or official
closing prices.

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 a rate quoted by a major bank or dealer in the particular currency market,
as reported by a recognized quotation dissemination service.

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, the difference in the foreign exchange rates between the trade
and settlement


11



                        NOTES TO SCHEDULES OF INVESTMENTS
                                   (unaudited)

dates on securities transactions, and the difference between the amounts of
dividends, interest and foreign withholding taxes recorded on the ex-date or
accrual 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 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 purchased
call options is increased by premiums paid. The proceeds from securities sold
through the exercise of purchased 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 written options. 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 written 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 written 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.

NOTE 2 - INVESTMENTS

The following information is presented on an income tax basis as of July 31,
2006. Differences between amounts for financial statements and Federal income
tax purposes are primarily due to timing differences.

The cost basis of investments for Federal income tax purposes at July 31, 2006
was as follows:

                                             --------------
Net unrealized appreciation (depreciation)   $    2,946,775

NOTE 3 - 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, among other things, 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 forward exchange rates, and an unrealized gain or loss is
recorded. The Fund realizes a gain or loss when a position is closed or upon
settlement of the contracts. There were no open forward foreign currency
contracts at July 31, 2006.

NOTE 4 - SYNTHETIC CONVERTIBLE SECURITIES

The Fund may establish a "synthetic" convertible instrument by combining
separate securities that possess the economic characteristics similar to a
convertible security, i.e., fixed-income securities ("fixed-income component",
which may be a convertible or non-convertible security) and the right to acquire
equity securities ("convertible component"). The fixed-income component is
achieved by investing in 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 establishing a synthetic instrument, the Fund may
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 convertible instruments 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 5 - 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 or twenty-eight days based on the results of an auction. Dividend rates
ranged from 3.60% to 5.30% for the nine-month period ended July 31, 2006. Under
the 1940 Act, 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 Fund's option, 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 only the holders of common stock, when the respective
classes vote alone.

NOTE 6 - 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 Fund's net asset value. 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
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 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. Net unrealized
gains are reported as an asset and net unrealized losses are reported as a
liability on the Statement of Assets and Liabilities. The change in the value of
the swaps, including periodic amounts of interest to be paid or received on
swaps is reported as unrealized gains or losses in the Statement of Operations.
A realized gain or loss is recorded upon payment or termination of swap
agreements. Details of the swap agreements outstanding as of July 31, 2006 were
as follows:

NOTE 7 - SECURITIES LENDING

During the nine-month period ended July 31, 2006, the Fund loaned 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 continues to receive the equivalent of the interest or dividends
paid by the issuer on the securities loaned and also receives 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 has 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 does 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) the expenses of
enforcing its rights. In an effort to reduce these risks, Calamos Advisors LLC
and the security lending agent will monitor the creditworthiness of the firms to
which the Fund lends securities. At July 31, 2006, the Fund had securities
valued at $151,676,027 that were on loan to broker-dealers and banks and
$155,341,197 in cash or cash equivalent collateral.
