President's Letter

[PHOTO OF JOHN P. CALAMOS]

Dear Shareholder,

Thank you for your investment in the CALAMOS CONVERTIBLE OPPORTUNITIES AND
INCOME FUND (CHI). We submit for your review this annual shareholder report for
the 12-month period ended October 31, 2005.

As a reminder, the Fund blends convertible and high-yield securities in a
portfolio designed to provide a consistent, attractive monthly distribution
while providing investors with some exposure to the upside potential of the
equity markets. Because convertible and high-yield securities tend to follow the
movements of their companies' equity counterparts more than traditional fixed
income securities, the Fund can be viewed as having a significant income
component, yet with equity sensitivity.

================================================================================
For up-to-date information on Calamos Convertible Opportunities and Income Fund,
please visit www.calamos.com. Here you will find timely portfolio details, our
outlook, and special reports.
================================================================================

During the 12-month period, the Fund produced a total return of 6.69% at net
asset value (NAV), comparing favorably with the annual total return of the
convertible market (as represented by the Merrill Lynch Yield Alternatives
Index, which declined by -0.76%), and the high-yield market (as represented by
the CSFB High Yield Index, which returned 3.53%). The Fund's market price (which
is determined by the secondary market and may be higher or lower than the Fund's
NAV) surpassed these annual returns with a total return gain of 10.40%. During
this period, the Fund delivered a total of $1.825 per share in monthly
distributions to shareholders, comprised of earned income and short-term capital
gains. In addition, the Fund paid a long-term capital gains distribution of
$1.036 in January 2005, reflecting the capacity for the Fund's holdings to not
only generate income, but to also experience capital appreciation.

One important development during the year came in June 2005, when we announced
the Fund's adoption of a level rate distribution policy. In our opinion, a level
rate policy combined with an attractive monthly distribution will benefit
long-term investors in the Fund, as we believe that closed-end fund investors
consider consistent and significant distributions to be an important component
of their long-term total-return goals. (If any distribution exceeds the Fund's
net investment company taxable income, the excess will generally be a tax-free
return of capital.)

As portfolio managers, our job is to focus on delivering to shareholders an
attractive long-term total return, which includes a consistent monthly
distribution. We believe that by combining convertible- and corporate
fixed-income securities that provide significant income as well as exposure to
the equity market's upside potential, we can offer our shareholders the
potential for long-term wealth creation in a manner consistent with our focus on
risk management. Looking ahead, we will strive to deliver to shareholders a
dependable distribution that contributes to the Fund's total return while
providing current income and limiting downside exposure.

President's Letter

A convenient means to accumulate more shares is via the Fund's dividend
reinvestment plan. The plan offers current shareholders an efficient method of
purchasing additional shares with a potential for cost savings. For example, if
the Fund's shares are trading at a premium, dividends will be automatically
reinvested through the plan at NAV or 95% of the market price, whichever is
greater; if shares are trading at a discount, dividends will be reinvested by
purchasing shares at the market price, below NAV. Please see the Fund's dividend
reinvestment plan for more information.

We appreciate your investment in the CALAMOS CONVERTIBLE OPPORTUNITIES AND
INCOME FUND, and look forward to serving your long-term investment plan in the
coming months and years ahead. For up-to-date information on the Fund, details
of its dividend reinvestment plan, and other information including our market
outlook, please visit www.calamos.com.

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.

   Convertible Opportunities and Income Fund
14 ANNUAL REPORT Statement of Changes in Net Assets



Notes to Financial Statements

NOTE 1 - ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION. CALAMOS Convertible Opportunities and Income Fund (the "Fund") was
organized as a Delaware statutory trust on April 17, 2002 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 June
26, 2002.

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. In computing the Fund's net asset value, portfolio
securities that are traded on a securities exchange in the United States, except
an option security, are valued at the last reported sale price as of the time of
valuation, or lacking any current reported sale at the time of valuation, at the
mean between the most recent bid and asked quotations. Each option security
traded on a securities exchange in the United States is valued at the last
current reported sale price as of the time of valuation if the last current
reported sale price falls within the consolidated bid/ask quote for the option
security. If the last current reported sale price as of the time of valuation
does not fall within the consolidated bid/ask quote for the option security, the
security is valued at the midpoint of the consolidated bid/ask quote for the
option security. Each security traded in the over-the-counter market and quoted
on the NASDAQ National Market System, is 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 by NASDAQ, or lacking any
current reported sale on NASDAQ at the time of valuation, at the mean between
the most recent bid and asked quotations. Each over-the-counter option that is
not traded through the Options Clearing Corporation is valued by the
counterparty, or if the counterparty's price is not readily available then by
using the Black-Scholes method. Each other security traded over-the-counter is
valued at the mean between the most recent bid and asked quotations. 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 priced at a fair value following procedures and/or guidelines
approved by the Board of Trustees, which may include utilizing a systematic fair
valuation model provided by an independent pricing system. The Funds' may also
use fair value pricing if the value of a security it holds is, pursuant to Board
of Trustees' guidelines, materially affected by events occurring before the
Funds' pricing time but 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, 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 Funds' net asset value may differ from quoted or
official closing prices.

Securities that are principally traded in a foreign market are valued at the
last current sale price at the time of valuation or lacking any current or
reported sale, at the time of valuation, at the mean between the most recent bid
and asked quotations 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 priced at a fair value following procedures approved by the
Board of Trustees. In light of the judgment involved in fair value decisions,
there can be no assurance that a fair value assigned to a particular security is
accurate.

                                  Notes to Financial Statements ANNUAL REPORT 15



Notes to Financial Statements

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. Except for securities of foreign issuers valued by
a pricing service, values of investments and other assets and liabilities
denominated in foreign currencies are translated into U.S. dollars using a rate
selected by the advisor from rates quoted by any 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, foreign 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 currency appreciation
and depreciation 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
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 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.

USE OF ESTIMATES. The preparation of financial statements in conformity with
U.S. generally accepted accounting principles requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results may differ from those
estimates.

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 U.S. generally accepted accounting
principles. To the extent 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 fixed income securities. Financial records
are not adjusted for temporary differences.

Effective June 1, 2005, the Fund adopted a level rate monthly distribution to
common shareholders, which may be modified by the Board of Trustees from time to
time. Monthly distributions may include net investment income, net realized
short-term capital gains and, if necessary, return of capital. In addition,
distributions may include net realized long-term capital gains to the extent
permitted by the 1940 Act.

In order to make these monthly distributions, the Fund might have to sell a
portion of its investment portfolio at a time when independent investment
judgment might not dictate such action. Also, for purposes of maintaining level
rate distributions the Fund may realize short-term capital gains on securities
that, if sold at a later date, would have resulted in long-term capital gains.
Maintenance of level rate distributions may increase transaction and tax costs
associated with the Fund.

INDEMNIFICATIONS. Under the Fund's organizational documents, its Officers and
Trustees are indemnified against certain liabilities arising out of the
performance of their duties to the Fund. In addition, in the normal course of
business, the Fund enters into contracts that provide general indemnifications
to other parties. The Fund's maximum exposure under these arrangements is
unknown as this would involve future claims that may be made against the Fund
that have not yet occurred. However, the Fund has not had prior claims or losses
pursuant to these contracts and expects the risk of loss to be remote.

NOTE 2 - INVESTMENT ADVISOR 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 Fund's total
assets (including any assets attributable to any leverage that may be
outstanding) minus 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 0.25% of the average weekly managed assets
of the Fund for the first five full years of the Fund's operation (through June
30, 2007) and to waive a declining amount for an additional three years (0.18%
of the average weekly managed assets in 2008, 0.11% in 2009, and 0.04% in 2010).

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 total average daily net assets of Calamos Investment Trust and Calamos
Advisors Trust and the average weekly managed assets of Calamos Convertible and
High Income Fund, Calamos Convertible Opportunities and Income Fund, Calamos
Strategic Total Return Fund and Calamos Global Total Return Fund). 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
assets and liabilities and monitoring trustee deferred compensation plan
accruals and valuations. The Fund will pay its pro rata share of the financial
accounting service fee payable to Calamos Advisors based on the Fund's relative
portion of combined assets.

Effective August 1, 2005 the Fund began reimbursing the advisor for a portion of
the compensation paid to the Chief Compliance Officer of the Trust. This
compensation is reported as part of "Other" expenses on the Statement of
Operations.

Certain officers and Trustees of the Fund are also officers and directors of
Calamos Financial Services LLC ("CFS") and Calamos Advisors. All officers and
affiliated Trustees serve without direct compensation from the Fund.

Notes to Financial Statements

The Fund has adopted a deferred compensation plan (the "Plan"). Under the Plan,
a trustee who is not an "interested person" (as defined in the 1940 Act) of CFS
or 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 participating trustee. The value of a participating
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 $37,538 are included in
"Other assets" on the Statement of Assets and Liabilities at October 31, 2005.
The Fund's obligation to make payments under the Plan is a general obligation of
the Fund and is included in "Payable for deferred compensation to Trustees" on
the Statement of Assets and Liabilities at October 31, 2005.

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, 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 upon settlement of the contracts.
There were no open forward foreign currency contracts at October 31, 2005.

NOTE 7 - 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")
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
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 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.

Notes to Financial Statements

NOTE 8 - PREFERRED SHARES

There are unlimited shares of Auction Market Preferred Shares ("Preferred
Shares") authorized. The Preferred Shares have rights as determined by the Board
of Trustees. The 15,360 shares of Preferred Shares outstanding consist of seven
series, 2,040 shares of M, 2,040 shares of TU, 2,040 shares of W7, 2,400 shares
of W28, 2,400 shares of TH7, 2,040 shares of TH28, and 2,400 shares of F. 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 1.90% to 3.90% for the year October 31, 2005. Under the 1940 Act,
the Fund may not declare dividends or make other distributions on shares of
common stock or purchases 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 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 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 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. Net unrealized
gains are reported as an asset or 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 October 31, 2005
were as follows:



                                                                                                                    UNREALIZED

NOTE 10 - SECURITIES LENDING

During the year ended October 31, 2005 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 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 and the security
lending agent will monitor the creditworthiness of the firms to which the Fund
lends securities. At October 31, 2005, the Fund had securities valued at
$134,752,944 that were on loan to broker-dealers and banks and $137,667,173 in
cash or cash equivalent collateral.

(a)   Net of sales load of $0.675 on initial shares issued and beginning net
      asset value of $14.325.

(b)   Interest rate swap payment reclassed from net investment income (loss) to
      net realized and unrealized gain (loss) on investments, foreign currency
      and interest rate swaps.

(c)   Based on average shares method.

(d)   Amount equated to less than $0.005 per common share.

(e)   Total investment return is calculated assuming a purchase of common stock
      on the opening of the first day and a sale on the closing of the last day
      of the period reported. Dividends and distributions are assumed, for
      purposes of this calculation, to be reinvested at prices obtained under
      the Fund's dividend reinvestment plan. Total return is not annualized for
      periods less than one year. Brokerage commissions are not reflected. NAV
      per share is determined by dividing the value of the Fund's portfolio
      securities, cash and other assets, less all liabilities, by the total
      number of common shares outstanding. The common share market price is the
      price the market is willing to pay for shares of the Fund at a given time.
      Common share market price is influenced by a range of factors, including
      supply and demand and market conditions.

(f)   Annualized for periods less than one year.

(g)   Does not reflect the effect of dividend payments to Preferred
      Shareholders.

(h)   Calculated by subtracting the Fund's total liabilities (not including
      Preferred Shares) from the Fund's total assets and dividing this by the
      number of Preferred Shares out- standing.

22 ANNUAL REPORT Financial Highlights



Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareholders of Calamos Convertible Opportunities
and Income Fund

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Calamos

Convertible Opportunities and Income Fund (the "Fund") as of October 31, 2005,
and the related statement of operations for the year then ended, the statements
of changes in net assets for each of the two years then ended and the financial
highlights for each of the three years then ended. 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 audit. The Fund's financial highlights for the
period ended October 31, 2002 were audited by other auditors whose report, dated
December 16, 2002, expressed an unqualified opinion on those financial
highlights.

We conducted our audit 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. The Fund
is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. Our audit included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Fund's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of October 31, 2005, by correspondence with the Fund's
custodian and brokers. We believe that our audit 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, 2005, the results of its operations for the year then
ended, the changes in its net assets for each of the two years then ended, and
the financial highlights for each of the three years then ended, in conformity
with accounting principles generally accepted in the United States of America.

Trustee Approval of Management Agreement

The Board of Trustees of the Fund oversees the Fund's management and, as
required by law, determines annually whether to continue the Fund's management
agreement with Calamos Advisors under which Calamos Advisors serves as the
investment manager for the Fund.

In connection with their most recent consideration of that agreement, the
Trustees received and reviewed information provided by Calamos Advisors in
response to detailed requests of the Independent Trustees and their independent
legal counsel and discussed with representatives of Calamos Advisors' the Fund's
operations and the nature and quality of the advisory and other services
provided by Calamos Advisors to the Fund. The Trustees also received and
reviewed a memorandum from counsel to the Independent Trustees regarding the
Trustee's responsibilities in evaluating the management agreement. In the course
of their consideration of the agreement the Independent Trustees were advised by
their counsel, and in addition to meeting with management of Calamos Advisors,
they met separately in executive session with their counsel.

At a meeting on June 30, 2005, based on their evaluation of the information
referred to above and other information, the Trustees determined that the
overall arrangements between the Fund and Calamos Advisors were fair and
reasonable in light of the nature and quality of the services provided by
Calamos Advisors and its affiliates, the fees charged for those services and
other matters that the Trustees considered relevant in the exercise of their
business judgment. At that meeting the Trustees, including all of the
Independent Trustees, unanimously approved continuation of the management
agreement through August 1, 2006, subject to earlier termination as provided in
the agreement.

In considering the continuation of the management agreement, the Trustees
reviewed and analyzed various factors that they determined were relevant,
including the factors described below, none of which by itself was considered
dispositive. However, the material factors and conclusions that formed the basis
for the Trustees' determination to approve the continuation of the management
agreement are discussed separately below.

NATURE, QUALITY AND EXTENT OF SERVICES

The Trustees reviewed the nature, extent and quality of Calamos Advisors'
services to the Fund, taking into account the investment objective and strategy
of the Fund and the knowledge of the Trustees gained from their regular meetings
with management on at least a quarterly basis. In addition, the Trustees
reviewed Calamos Advisors' resources and key personnel, especially those who
provide investment management services to the Fund. The Trustees also considered
other services provided to the Fund by Calamos Advisors, such as managing the
execution of portfolio transactions and the selection of broker-dealers for
those transactions, monitoring adherence to the Fund's investment restrictions,
producing shareholder reports, providing support services for the Board and
Board committees, communicating with shareholders and overseeing the activities
of other service providers, including monitoring compliance with various Fund
policies and procedures and with applicable securities laws and regulations.

The Trustees concluded that the nature and extent of the services provided by
Calamos Advisors to the Fund were appropriate and consistent with the terms of
the management agreement, that the quality of those services had been consistent
with or superior to quality norms in the industry and that the Fund was likely
to benefit from the continued provision of those services. They also concluded
that Calamos Advisors had sufficient personnel, with the appropriate education
and experience, to serve the Fund effectively and had demonstrated its
continuing ability to attract and retain well qualified personnel.

PERFORMANCE

The Trustees considered the Fund's performance results over various time
periods. They reviewed information comparing the Fund's performance with the
performance of comparable funds and peer groups identified by Lipper Inc., an
independent provider of investment company data, and with the Fund's benchmark.
The Trustees noted that the Fund had less than three years of performance data,
and thus did not have a long-term performance record. The Trustees concluded
that given the short performance history, performance was not the most important
factor in the Trustees' evaluation of the quality of services provided by
Calamos Advisors under the management agreement.

The Trustees examined information on fees and expenses of the Fund in comparison
to information for comparable funds as provided by Lipper. Also, the Trustees
reviewed information on fees and expenses for additional funds identified by
Calamos Advisors. The Trustees noted that the contractual rate of management
fees for the Fund was greater than the median management fees of its Lipper peer
group. They also noted, however, that the Fund's overall expense ratios were
below the median expense ratios of its peer group.

The Trustees considered the methodology used by Calamos Advisors in determining
compensation payable to portfolio managers, the very competitive environment for
investment management talent, and the competitive market for mutual funds in
different distribution channels.

The Trustees reviewed information on the profitability of Calamos Advisors in
serving as the Fund's investment manager and of Calamos Advisors and its
affiliates in all of their relationships with the Fund, as well as an
explanation of the methodology utilized in allocating various expenses among the
Fund and other business units. The Trustees recognized that profitability
comparisons among fund managers are difficult because very little comparative
information is publicly available and profitability of any manager is affected
by numerous factors, including the organizational structure of the particular
manager, the types of funds and other accounts it manages, possible other lines
of business, the methodology for allocating expenses and the manager's capital
structure and cost of capital. However, based on the information available and
taking those factors into account, the Trustees concluded that the profitability
of Calamos Advisors regarding the Fund in relation to the services rendered was
not unreasonable.

The Trustees also reviewed Calamos Advisors' management fees for its
institutional separate accounts and for its subadvised funds (for which Calamos
Advisors provides portfolio management services only). Although in most
instances its sub-advisory, and in many instances its institutional separate
account, fees for various investment strategies are lower than the management
fees charged to the Fund, the Trustees noted that Calamos Advisors performs
significant additional services for the Fund that it does not provide to those
other clients, including oversight of the Funds' other service providers,
trustee support, regulatory compliance and numerous other services.

Finally, the Trustees considered Calamos Advisors' financial condition, which
they found to be sound.

The Trustees concluded that the management fee and other compensation payable by
the Fund to Calamos Advisors and its affiliates were reasonable in relation to
the nature and quality of the services to be provided, taking into account the
fees charged by other advisors for managing comparable mutual funds with similar
strategies and the fees Calamos Advisors charges to other clients. The Trustees
also concluded that the Fund's estimated overall expense ratios, taking into
account quality of services provided by Calamos Advisors, the Fund's investment
performance and the expense limitations agreed to by Calamos Advisors, were also
reasonable.

ECONOMIES OF SCALE

In reviewing the Fund's fees and expenses, the Trustees examined the potential
benefits of economies of scale, and whether any economies of scale should be
reflected in the Fund's fee structure. They noted that the Fund has had a
relatively stable asset base since commencement of operations and that there do
not appear to have been significant economies of scale realized since that time.

OTHER BENEFITS TO CALAMOS ADVISORS

The Trustees also considered benefits that accrue to Calamos Advisors and its
affiliates from their relationship with the Fund. The Trustees concluded that,
other than the services to be provided by Calamos Advisors and its affiliates
pursuant to the management agreement and the fees payable by the Fund therefor,
the Fund and Calamos Advisors may potentially benefit from their relationship
with each other in other ways. The Trustees also considered Calamos Advisors'
use of commissions to be paid by the Fund on its portfolio brokerage
transactions to obtain proprietary research products and services benefiting the
Fund and/or other clients of Calamos Advisors. The Trustees concluded that
Calamos Advisors' use of "soft" commission dollars to obtain research products
and services was consistent with regulatory requirements and is beneficial to
the Fund. They concluded that, although Calamos Advisors derives or may derive
additional benefits through the use of soft dollars from the Fund's portfolio
transactions, the Fund also benefits from the receipt of research products and
services to be acquired through commissions paid on the portfolio transactions
of other clients of Calamos Advisors. They also concluded that the Fund's
success could attract other business to Calamos Advisors or its other funds and
that Calamos Advisors' success could enhance its ability to serve the Fund.

After full consideration of the above factors as well as other factors that were
instructive in analyzing the management arrangements, the Trustees, including
all of the Independent Trustees, concluded that the continuation of the
management agreement was in the best interest of the Fund and its shareholders.

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, Stephen B.

identification.
