Letter to Shareholders

Dear Fellow Shareholders:

We are pleased to submit to you our annual report for the year ended October 31,
2006. As always, we value and look forward to the opportunity to communicate
with you.

At CALAMOS INVESTMENTS, we view our communication with you as vitally important,
so we encourage you to review this report carefully. Inside, you will find
investment team commentary, share price and NAV performance, fund sector
allocation, fund holdings and financial highlights regarding your Calamos
closed-end fund. We hope that you find this report both informative and relevant
to your investment needs, and we welcome your feedback.

For information about your fund throughout the year, we invite you to visit our
website at www.calamos.com. There, you can find the most up-to-date fund
information. To help you interpret the big picture, we also post monthly manager
commentaries, which provide our latest economic and market outlook.

It has been an exciting year for the CALAMOS INVESTMENTS closed-end funds. All
four funds delivered strong positive performance while continuing to provide a
stable monthly distribution to shareholders. Unlike many traditional
fixed-income closed-end funds, Convertible Opportunities and Income Fund (the
"Fund") can be thought of as a complement to the fixed-income portion of your
asset allocation. With its unique structure that combines convertible and
high-yield securities, the Fund is designed to be less susceptible to rising
interest rates. Our focus on risk management, our success at blending asset
classes, and our long history of research expertise in lower-rated securities
all aim to benefit the Fund and its investors over the long term. For the fiscal
year ending October 31, 2006, the portfolio returned 10.47% based on NAV while
the market price returned 12.81%.

At Calamos, one of our key tenets is to maximize risk-adjusted return. One way
to improve total return is to reduce expenses, and one way you can help us
reduce expenses is to sign up for e-delivery by visiting our website and
clicking on the "Go Paperless!" link. By doing so, you will be able to view
important shareholder communications online--including fund prospectuses,
shareholder reports and proxy statements--long before the printed publications
would have arrived by traditional mail.

We are firm believers in remaining positioned for the long term and have long
recognized the impossibility of predicting the exact timing of market shifts.
Accordingly, we continue to position our portfolios ahead of events and market
turns rather than trying to chase them. Based on our view that the economy is in
a period of mid-cycle slowdown, which we explain at greater length in the
"Economic and Market Review" that follows, we are emphasizing investments in
companies with quality characteristics--such as low debt, high return on
invested capital, capable management and well-planned business strategies.


                                    Convertible Opportunities and Income Fund
                                         Letter to Shareholders ANNUAL REPORT  1

   Convertible Opportunities and Income Fund
2  ANNUAL REPORT Letter to Shareholders



Economic and Market Review

     For the latest market and economic outlook, please visit our website at
          www.calamos.com and select the "Individual Investors" button.

Mid-cycle slowdowns are typically characterized by a number of factors, most of
which are present today:

-    An end to Fed rate hikes

-    Moderation of energy prices

-    Slowing in the housing market

-    Increasing market volatility

-    Moderation of consumer spending

-    Declining commodity prices

Historically, mid-cycle slowdowns have been accompanied by a shift in market
leadership from cyclical investments to growth-oriented investments. Across the
Calamos Funds, we are favoring companies we believe have good prospects for
sustainable growth and reduced sensitivity to the economy. Our investment
discipline and outlook have led us to a number of traditional large-cap growth
companies trading at prices we believe are very attractive relative to the broad
market and historical values.

During the 12-month period ended October 31, 2006, market participants found
themselves distracted by crosscurrents of economic data. In the United States,
declines in gross domestic product growth, sliding home prices and
rising--though modest-- inflation troubled investors. Yet, there was better news
as well. The Fed paused its rate tightening in August, improving sentiment
somewhat. And despite OPEC's decision to reduce oil supplies, gasoline prices
dropped. Furthermore, corporate earnings and balance sheets remained strong.

Broadly, stocks advanced in the U.S. market, with the S&P 500 Index(1) rising
16.34% for the 12-month period. This solid return was achieved at a pace that
was far from consistent. After a slow summer, a substantial portion of the S&P
500 Index's performance was earned during the final three months of the period.
And, not all stocks were equally rewarded, as growth-oriented stocks trailed
value and cyclical issues.

International stocks performed with even greater strength and the MSCI EAFE(R)
Index(2) gained 28.04% for the 12-month period. Meanwhile, convertible
securities and high-yield issues participated in the rise of the equity markets.
The Value Line Convertible Index(3) returned 10.43% for the 12-month period and
the CS High Yield Index(4) returned 10.29% for the 12-month period.

We believe the U.S. economy--while remaining fundamentally strong--is in the
midst of a mid-cycle slowdown. The current environment draws parallels to other
mid-cycle slowdowns, including those of the mid-1960s, mid-1980s, and mid-1990s.
In each of these periods, the Fed initiated an interest rate tightening campaign
that caused a slowdown, first in the investment markets and then in the economy
as reflected by waning gross domestic product (GDP) growth. Although no one can
predict where a change in the economy will occur, each of these past economic
slowdowns was followed by a solid upswing in the markets driven by securities in
traditional, stable-growth companies. Accordingly, we believe that the current
mid-cycle slowdown can bring considerable opportunity for long-term investors
such as ourselves.

Although we do believe the U.S. economy is in the middle of a slowdown, we do
not believe a recession is imminent. With three consecutive pauses, we believe
the Fed is near or at the end of its tightening phase, and this could serve as a
catalyst for stronger growth going forward. Even though gross domestic product
growth has declined from the levels achieved during the economic expansion, we
believe growth remains respectable and is consistent with what we expect in a
period of mid-cycle slowdown. Moreover, our constructive outlook is supported by
the current strength in corporate balance sheets and earnings. And, with
corporations having cash to spend, we believe that corporate spending will
provide the fuel for economic growth. While gasoline prices remain high, they
have dropped considerably; this decline, along with increases to wages, could
spur increased consumer spending, which we believe will remain helpful for the
economy.

As always, we are firm believers in remaining positioned for the long term and
we have long recognized the impossibility of predicting the exact timing of
market shifts. And, as always, we continue to position our portfolios ahead of
events and market turns rather than trying to chase them. Based on our view that
the economy is in a period of mid-cycle slowdown, we're emphasizing investments
in companies with higher-quality characteristics such as low debt, high return
on invested capital, capable management and well-planned business strategies.

Q. HOW DID THE FUND PERFORM OVER THE REPORTING PERIOD?

A. As you know, Calamos Convertible Opportunities and Income Fund (CHI) offers
investors an enhanced fixed-income strategy focused on delivering an attractive
income stream with the potential for capital gains. The types of bonds that the
Fund typically holds (high-yield corporate and convertible securities) have
different characteristics than traditional bonds, providing an attractive
complement to a standard fixed-income allocation. As a result of its allocation,
the NAV of the Fund typically performs well in periods marked by economic
expansion, as convertible and high-yield bonds tend to be economically sensitive
compared with high-quality bonds, which are often more sensitive to changes in
interest rates. This distinction was especially clear during the first calendar
quarter of 2006, when traditional bonds experienced negative returns while
equity-sensitive high-yield and convertible bonds enjoyed gains. It is also
worth noting that since the Fund's holdings have different sensitivities than
traditional bonds, the Fund can further diversify the income-focused portion of
an investor's asset allocation.

Based on performance results, the Fund's investment strategy proved its
effectiveness these past 12 months. The Fund finished strong for the annual
period ended October 31, 2006. Its underlying portfolio (as represented by net
asset value or NAV) returned 10.47% during the 12-month period, while the Fund's
market price returned 12.81%. This compares with a return of 10.29% for the CS
High Yield Index. In addition, the Fund has maintained a stable distribution of
at least $0.1500 per share since June 2003.

Q. WHAT MAJOR DEVELOPMENTS OCCURRED WITH THE ECONOMY AND MARKET THIS PAST YEAR,
AND HOW DID THESE FACTORS AFFECT THE FUND?

A. Rising short-term interest rates were the big story through the first half of
2006,

though they had little impact on the Fund's cost of leverage. Many closed-end
funds use leverage by borrowing funds at very short-term rates. As short-term
interest rates rise, this increases the cost of leverage and can impact the
yield and total return of the portfolio. While the Fund does employ leverage in
the form of preferred shares, a majority of the cost of leverage was locked in
for longer periods earlier in the interest rate cycle, when rates were lower.
Because the cost of leverage was locked in at longer-term fixed rates, the
portfolio was not significantly affected by the rising short-term interest rates
that marked 2005 and the first half of 2006.

Long-term interest rates also rose over the period, with the yield on the
10-year Treasury moving from 4.57% at the beginning of the fiscal period to
5.15% in June 2006 before falling off in the third calendar quarter. Rising
long-term interest rates tend to negatively affect high-quality fixed-income
securities. The Fund's portfolio combines high-yield corporate bonds and
convertible bonds that tend to be more economically sensitive and much less
interest-rate sensitive. This was demonstrated over the period as the portfolio
benefited from continued economic growth and a general rise in the equity
market.

Mixed economic data stirred up investor apprehension at the start of the third
calendar quarter of 2006. This anxiety spurred a continuation of the saw-toothed
markets of the second quarter, when stocks would rise for a few days or weeks,
only to retreat again. By the end of September, however, the landscape had
significantly changed. Markets gained a degree of traction, and major stock
indexes around the globe posted solid gains for the quarter. Convertible and
high-yield securities participated in the equity market upside during the
period, earning respectable returns as well.

Despite media reports of decreased consumer spending, a downward revision of
gross domestic product (GDP) growth and higher year-over-year inflation, there
was considerable good news in the third quarter. The Fed's decision in August to
pause its rate increases served to alleviate recession fears, and investors
became cautiously hopeful of economic expansion. Corporate earnings remained
robust. The release of strong consumer confidence data, in part a reaction to
the continuing slide of gasoline prices, encouraged investors as well. In fact,
energy prices continued to drop through October, despite

OPEC's announcement that it would cut production. These positive events
contributed to a robust market with the S&P 500 rising 3.26% in October alone.

Our analysis indicates that the economy is in the midst of a mid-cycle slowdown
much like those of 1965, 1985-86 and 1995. However, we don't believe the risk of
inflation or recession is high at this time. One significant change that
occurred in past mid-cycle slowdowns was a shift from a pro-cyclical market to a
more growth-oriented market. The portfolio's emphasis on higher-quality
sustainable growth names and reduction in the cyclical sectors positions it well
for a rotation in market leadership to stable growth.

Q. WHAT WORKED WELL FOR THE FUND OVER THE PERIOD?

A. Both of the Fund's main asset classes (high-yield corporates and convertible
bonds) posted positive returns for the fiscal year. The portfolio benefited from
our focus on more equity-sensitive convertible securities--which performed
well--reflecting the positive returns in their underlying equities. The
portfolio's convertible holdings got an added boost as valuations in the
convertible market continued to improve over the period. At the end of the
period, the Fund's allocation was 42% in convertibles and 55% in high-yield
corporate bonds.

From a sector standpoint, all of the portfolio's sector allocations delivered
positive performance, with several of the sectors providing double-digit
returns. Relative to the CS High Yield Index, security selection in financials
and utilities racked up the biggest gains. Selection among larger-cap securities
also proved advantageous.

Q. WHAT HAMPERED THE FUND'S PERFORMANCE?

A. Relative to the benchmark, an underweight position and security selection
within the materials sector, while still positive, detracted from performance,
as did security selection in the consumer discretionary sector. In addition, the
portfolio's higher credit quality relative to the index held back performance,
as low-quality issues performed well. From a long-term, risk/reward perspective,
however, we maintain that our rigorous credit research will benefit clients over
the full course of a market cycle.

Q. THE FUND USES SWAP AGREEMENTS TO LIMIT THE INTEREST-RATE RISK OF LEVERAGE.
WHAT WILL YOU DO AS THESE SWAPS ROLL OFF?

A. In order to avoid a significant impact on the portfolio, the maturities of
the swap agreements have been staggered over a two-year time period. While we
will continue to actively evaluate the opportunity to use swaps, given the
current economic environment and the low likelihood of near-term interest rate
increases, it does not appear to be advantageous to lock in rates by entering
into new swap agreements. See the section titled "Leverage" to learn how the
Fund uses leverage and swap agreements to enhance total return and manage
interest-rate risk.

Q. WHAT IS YOUR OUTLOOK IN THE COMING YEAR AND HOW ARE YOU POSITIONING THE
PORTFOLIO ACCORDINGLY?

A. We believe convertible bonds continue to offer an attractive risk/reward
balance for

investors. Although the convertible valuation gap has narrowed significantly
this past year, we believe room for valuation improvement remains, which should
continue to benefit investors. Convertible new issuance was stronger for the
third quarter than it has been for much of the year, but redemptions remained
fairly high. However, now that interest rates have moved away from historic
lows, it is possible that companies seeking access to capital could be more
inclined to consider convertible debt rather than alternatives such as straight
high-yield bonds, particularly if the equity market can maintain its upward
pace. We are focusing on equity-sensitive issues so that we can continue to
participate in any upward movement of the stock market, of these, we're favoring
higher-quality, sustainable-growth issues. At the same time, we have reduced our
weightings in cyclicals such as energy, industrials and materials; we believe
cyclical businesses that owe their growth to volatile commodity prices or to
recovery-level growth in the GDP pose higher risk today than more stable growth
issues.

The fundamentals of the high-yield market remain solid, and we believe the
market looks fairly priced: defaults are low, corporate balance sheets are sound
and companies have sufficient cash on hand to service their debts. As high-yield
issues are typically more economically sensitive than interest-rate sensitive,
these securities should benefit from continued economic growth. While remaining
attuned to top-down concerns, we emphasize an issue-by-issue approach in our
high-yield portfolios. We look for companies with good return on invested
capital and stable or improving credit position; we also favor companies that
may benefit from equity issuance or M&A activity. As in many of our other
strategies, we have a bias toward sustainable growth companies over those with
cyclical vulnerabilities. We are avoiding distressed issues, instead positioning
our portfolios with a bias toward securities in the higher quality tiers of the
high-yield universe. Given that the performance of high-yield bonds is equity
sensitive, our research seeks to determine the financial strength and prospects
of issuing companies-- as well as catalysts for upside.

Q. ANY FINAL THOUGHTS FOR INVESTORS?

A. We are firm believers in remaining positioned for the long term and have long
recognized the impossibility of predicting the exact timing of market shifts.
Accordingly, we continue to attempt to position our portfolios ahead of events
and market turns, rather than trying to chase them. Based on our economic
outlook, we continue to emphasize investments in companies with quality
hallmarks--such as strong balance sheets, capable management and well-planned
business strategies. We have found many opportunities to invest in these
companies at what we believe are very attractive prices. We thank you for your
continued support and look forward to helping you attain your financial goals.

NOTES TO SCHEDULE OF INVESTMENTS

Note: Value for Securities denominated in foreign currencies are shown in U.S.
dollars.

*    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, 2006, the market value
     of 144A securities that were not subject to mandatory issuer registration
     obligations is $72,873,655 or 9.4% of net assets.

@    Security, or portion of security, is on loan.

#    Non-income producing security.

++   Variable rate or step bond security. The interest rate shown is the rate in
     effect at October 31, 2006.

&    Securities exchangeable or convertible into securities of an entity
     different than the issuer. Such entity is identified in the parenthetical.

    Convertible Opportunities and Income Fund

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. Calamos Advisors LLC ("Calamos Advisors") 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.

Trading in securities on European and Far Eastern securities exchanges and OTC
markets is typically completed at various times before the close of business on
each day on which the NYSE is open. Each security trading on these exchanges or
OTC markets is evaluated utilizing a systematic fair valuation model provided by
an independent pricing service approved by the Board of Trustees. The valuation
of each security that meets certain criteria in relation to the valuation model
is systematically adjusted to reflect the impact of movement in the U.S. market
after the foreign markets close. Securities that do not meet the criteria, or
that are principally traded in other foreign markets, 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, in accordance with guidelines
adopted by the Board of Trustees. Trading of foreign 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.

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. 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 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 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.

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 U.S. income taxes because the
Fund's policy is to continue to qualify as a regulated investment company under
the Internal Revenue Code of 1986, as amended (the "Code") and distribute to
shareholders substantially all of its taxable income and net realized 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.

INDEMNIFICATIONS. Under the Fund's organizational documents, its officers and
trustees are indemnified against certain liabilities incurred by them by reason
of having been an officer or trustee of 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.

NEW ACCOUNTING PRONOUNCEMENTS. On July 13, 2006, the Financial Accounting
Standards Board (FASB) released FASB Interpretation No. 48 Accounting for
Uncertainty in Income Taxes (FIN 48). FIN 48 provides guidance for how uncertain
tax positions should be recognized, measured, presented and disclosed in the
financial statements. FIN 48 requires the evaluation of tax positions taken in
the course of preparing the Fund's tax returns to determine whether the tax
positions are "more-likely-than-not" of being sustained by the applicable tax
authority. Tax benefits of positions not deemed to meet the
more-likely-than-not threshold would be recorded as a tax expense in the current
year. Adoption of FIN 48 is required for fiscal years beginning after December
15, 2006 and is to be applied to all open tax years as of the effective date. At
this time, management is evaluating the implications of FIN 48 and its impact on
the financial statements has not yet been determined.

In addition, in September 2006, the Statement of Financial Accounting Standards
No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for
fiscal years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the impact the
adoption of SFAS 157 will have on the Fund's financial statements and their
disclosures and its impact has not yet been determined.

NOTE 2 - INVESTMENT ADVISOR AND TRANSACTIONS WITH AFFILIATES OR CERTAIN OTHER
PARTIES

Pursuant to an investment advisory agreement with Calamos Advisors LLC, the Fund
pays an annual fee, payable monthly, equal to 0.80% based on the average weekly
managed assets. 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).

Pursuant to a financial accounting services agreement, 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 of the average
daily net assets of Calamos Investment Trust, 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
monitoring trustee deferred compensation plan accruals and valuations. The Fund
pays its pro rata share of the financial accounting services fee payable to
Calamos Advisors based on the Fund's relative portion of combined assets.

The Fund reimburses the advisor for a portion of compensation paid to the Fund's
Chief Compliance Officer. This compensation is reported as part of "Trustees'
fees and officer compensation" expenses on the Statement of Operations.

Included in the statement of operations under the caption "Earnings credits" is
an expense offset of $10,515, arising from credits on cash balances maintained
on deposit.

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, except for
the Chief Compliance Officer as described above.

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 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. Deferred
compensation of $51,145 is included in "Other assets" on the Statement of Assets
and Liabilities at October 31, 2006. The Fund's obligation to make payments
under the Plan is a general obligation of the Fund and is included on the
Statement of Assets and Liabilities as a payable for "Deferred compensation to
Trustees" at October 31, 2006.

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 when a position is closed or upon
settlement of the contracts. There were no open forward foreign currency
contracts at October 31, 2006.

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",
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.

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 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 3.50% to 5.36% for the year ended October 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%.

                                Notes to Financial Statements  ANNUAL REPORT  23


Notes to Financial Statements

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 9 - INTEREST RATE TRANSACTIONS

The Fund may engage in swaps primarily to manage duration and yield curve risk,
or as alternatives to direct investments. Unrealized gains are reported as an
asset and unrealized losses are reported as a liability on the Statement of
Assets and Liabilities. The change in value of swaps, including accruals of
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 receipt of a periodic payment or termination of
the swap agreements. Swap agreements are stated at fair value. Notional
principal amounts are used to express the extent of involvement in these
transactions, but the amounts potentially subject to credit risk are much
smaller.

Premiums paid to or by the Fund are accrued daily and included in realized gain
(loss) when paid on swaps in the accompanying Statement of Operations. The
contracts are marked-to-market daily based on dealer-supplied valuations and
changes in value are recorded as unrealized appreciation (depreciation). Gains
or losses are realized upon early termination of the contract. Risks may exceed
amounts recognized in the Statement of Assets and Liabilities. These risks
include changes in the returns of the underlying instruments, failure of the
counterparties to perform under the contracts' terms and the possible lack of
liquidity with respect to the contracts.

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 additional to redeeming all or some of the Preferred Shares.

Details of the swap agreements outstanding as of October 31, 2006 were as
follows:



                                                                                     UNREALIZED

NOTE 10 - SECURITIES LENDING

During the year ended October 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 October 31, 2006, the Fund had securities
valued at $131,677,235 that were on loan to broker-dealers and banks and
$136,928,000 in cash or cash equivalent collateral.

     asset value of $14.325.

(b)  Interest rate swap payment reclassified 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 outstanding.

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, 2006, 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
four 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
audits. 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 audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audits 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 audits 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, 2006, by correspondence with the Fund's
custodian and brokers. We believe that our audits provide 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, 2006, 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 four years then ended, in conformity
with accounting principles generally accepted in the United States of America.

TRUSTEE APPROVAL OF MANAGEMENT AGREEMENT (UNAUDITED)

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 regarding the continuation 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 Trustees' 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 29, 2006, 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, 2007, 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
the sole factor in the Trustees' determinations. 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 Fund's investment objective and
strategy 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, overseeing the activities of
other service providers and 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 performance of the Fund 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 heard from representatives of Calamos Advisors, who
provided additional information with regard to certain aspects of the Lipper
materials and answered questions from the Trustees. The Trustees also noted that
the Fund had three years of performance data, and thus did not have a long-term
performance record. The Trustees concluded that the Fund's operating history was
too short a period to allow for a meaningful performance comparison.

Trustee Approval of Management Agreement (unaudited)

COSTS OF SERVICES AND PROFITS REALIZED BY CALAMOS ADVISORS

The Trustees examined information on the Fund's fees and expenses in comparison
to information for other comparable funds as provided by Lipper. The Trustees
noted that, although the Fund's contractual rate of management fees and actual
management fees after fee waivers for common shares were greater than the median
management fees of the Lipper peer group, the Fund's actual management fees
after fee waivers for common and preferred shares and overall expense ratio were
below those of its peer group.

The Trustees considered the methodology used by Calamos Advisors in determining
compensation payable to portfolio managers, the 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. Data was provided to the Trustees with respect to
profitability, both on a pre-and post-marketing cost basis. The Trustees also
reviewed the annual report of Calamos Advisors' parent company and discussed its
corporate structure. 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), as well as managed fees
for secondary accounts. Although in most instances its sub-advisory fees, and in
many instances its institutional separate accounts 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 administrative
services, oversight of the Fund's 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 fees 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 advisers 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 overall expense ratio was reasonable,
taking into account the quality of services provided by Calamos Advisors and the
Fund's investment performance.

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 operation and that there do
not appear to have been any 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 their agreements with the Fund 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 considered Calamos
Advisors' use of commissions 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

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 continuation of the management agreement for the
one-year period ending August 1, 2007, the Trustees, including all of the
Independent Trustees, concluded that the continuation of the management
agreement with Calamos Advisors was in the best interest of the Fund and its
shareholders.

About Closed-End Funds

WHAT IS A CLOSED-END FUND?

A closed-end fund is a publicly traded investment company that raises its
initial investment capital through the issuance of a fixed number of shares to
investors in a public offering. Shares of a closed-end fund are listed on a
stock exchange or traded in the over-the-counter market. Like all investment
companies, a closed-end fund is professionally managed and offers investors a
unique investment solution based on its investment objective approved by the
fund's Board of Directors.

ADVANTAGES OF CLOSED-END FUND INVESTING

-    DEFINED ASSET POOL ALLOWS EFFICIENT PORTFOLIO MANAGEMENT--Although
     closed-end fund shares trade actively on a securities exchange, this
     doesn't affect the closed-end fund manager because there are no new
     investors buying into or selling out of the fund's portfolio.

-    MORE FLEXIBILITY IN THE TIMING AND PRICE OF TRADES--Investors can purchase
     and sell shares of closed-end funds throughout the trading day, just like
     the shares of other publicly traded securities.

-    LOWER EXPENSE RATIOS--The expense ratios of closed-end funds are oftentimes
     less than those of mutual funds. Over time, a lower expense ratio could
     enhance investment performance.

-    CLOSED-END STRUCTURE MAKES SENSE FOR LESS-LIQUID ASSET CLASSES--A
     closed-end structure makes sense for investors considering less-liquid
     asset classes, such as high-yield bonds or micro-cap stocks.

-    ABILITY TO PUT LEVERAGE TO WORK--Closed-end funds may issue senior
     securities (such as preferred stock or debentures) or borrow money to
     "leverage" their investment positions.

-    NO MINIMUM INVESTMENT REQUIREMENTS

Leverage

USING LEVERAGE TO ENHANCE TOTAL RETURN

Closed-end funds can use leverage which utilizes borrowed money to increase the
return on invested capital. The Fund invests the borrowed assets into
securities, which we believe will provide a greater total return to investors
than the cost of the borrowing.

HIGHLIGHTS ON LEVERAGE

-    Leveraging the portfolio allows the investment team to potentially enhance
     the income and total returns of the Fund.

-    In a rising-rate environment, the cost of leverage typically increases. To
     protect against increases, the investment team has locked in the cost of
     leverage for a longer term. In leveraged closed-end funds that invest in
     interest-rate sensitive securities (high-quality traditional fixed income),
     rising rates can negatively impact a fund in two ways: increasing the cost
     of leverage and decreasing the value of securities.

-    This portfolio does not have notable sensitivity to rising interest rates.
     Much of the cost of leverage has been locked in, and the portfolio seeks to
     invest in securities that should be more economically sensitive and less
     interest rate-sensitive.

MANAGING THE INTEREST RATE RISK OF LEVERAGE

In general, leverage can expose a closed-end fund to the risk of fluctuations in
short-term interest rates. As we discussed in the Investment Team Interview,
Calamos Investments has taken steps to mitigate some of this risk to our
shareholders. Specifically, we hedged the Fund's preferred shares (used these
shares as principal) to enter into interest rate swap agreements. In its
simplest form, an interest rate swap involves two parties agreeing to exchange
or "swap" one set of cash flows for another set. In essence, the agreement
allows a party that desires to avoid a variable rate (Calamos) to pay a fixed
rate to a party that desires variability.

THE DEALER MARKET FOR INTEREST RATE SWAPS

                                  (FLOW CHART)

Under these agreements, the Fund pays a potentially higher rate for borrowing
initially, but that rate is fixed for a period of three to five years, thereby
potentially reducing the interest costs that the Fund would otherwise pay over
the period based on a floating or variable rate.

Level Rate Distribution Policy

USING A LEVEL RATE DISTRIBUTION POLICY TO PROMOTE DEPENDABLE INCOME AND TOTAL
RETURN

The goal of the level rate distribution policy is to provide investors a
predictable, though not assured, level of cash flow, which can either serve as a
stable income stream or, through reinvestment, contribute significantly to
long-term total return.

We understand the importance that investors place on the stability of dividends
and their ability to contribute to long-term total return, which is why we have
instituted a level rate distribution policy for the Fund. Under the policy,
monthly distributions paid may include net investment income, net realized
short-term capital gains and, if necessary, return of capital. In addition, a
limited number of distributions per calendar year may include net realized
long-term capital gains. There is no guarantee that the Fund will realize
capital gains in any given year. Distributions are subject to recharacterization
for tax purposes after the end of the fiscal year. All shareholders with taxable
accounts will receive written notification regarding the components and tax
treatment for distributions via Form 1099-DIV.

Distributions from the Fund are generally subject to Federal income taxes. For
purposes of maintaining the level rate distribution policy, 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 a level rate distribution
policy may increase transaction and tax costs associated with the Fund.

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 - $35,542 and $0 are the aggregate fees billed in each of 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

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,

The registrant's portfolio managers are responsible for managing the registrant
and other accounts, including separate accounts and unregistered funds.

Other than potential conflicts between investment strategies, the side-by-side
management of both the registrant and other accounts may raise potential
conflicts of interest due to the interest held by Calamos in an account and
certain trading practices used by the portfolio managers (e.g., cross trades
between the registrant and another account and allocation of aggregated
trades). Calamos has developed policies and procedures reasonably designed to
mitigate those conflicts. For example, Calamos will only place cross-trades in
securities held by the registrant in accordance with the rules promulgated under
the Investment Company Act of 1940 and has adopted policies designed to



ensure the fair allocation of securities purchased on an aggregated basis.

The portfolio managers advise certain accounts under a performance fee
arrangement. A performance fee arrangement may create an incentive for a
portfolio manager to make investments that are riskier or more speculative than
would be the case in the absence of performance fees. A performance fee
arrangement may result in increased compensation to the portfolio managers from
such accounts due to unrealized appreciation as well as realized gains in the
client's account.

(a)(3) The portfolio managers have each entered into employment agreements that
provide for compensation in the form of a minimum annual base salary, a maximum
discretionary target bonus and participation in various benefits programs. The
amounts paid to portfolio managers and the criteria utilized to determine the
amounts are benchmarked against industry specific data provided by third party
analytical agencies. The discretionary target bonus is set at a percentage of
base salary. Portfolio performance, as measured by risk-adjusted portfolio
performance over a rolling three-year period, is utilized to determine the
discretionary target bonus. The portfolio managers are also eligible to receive
annual equity awards under a long term incentive compensation program.

(a)(4) As of October 31, 2006, the end of the registrant's most recently
completed fiscal year, the dollar range of securities beneficially owned by each
portfolio manager in the registrant is shown below:
