July 10, 2006

Dear Shareholder:

As The  Arbitrage  Fund  operates  on a May 31 fiscal  year,  we are  pleased to
present this year's Annual Report  covering the period from June 1, 2005 through
May 31, 2006.  Looking back at the letter enclosed in last year's Annual Report,
one cannot help but observe what a difference a year makes.  In that letter,  we
noted  that signs of a healthy  merger  arbitrage  market  were at hand and that
although the  widening of spreads  might  provide a minor or  temporary  drag on
returns, the situation of negligible dealflow and low interest rates was rapidly
reversing itself to the benefit of merger  arbitrage.  In fact, it was and, as a
result,  the Fund's Class R Shares generated a return of 7.15% for the 12 months
ending May 31, 2006.

Since our last  Annual  Report to you,  the two key drivers of profits in merger
arbitrage: (1) higher interest rates and (2) normalized dealflow (in that order)
have indeed improved  substantially.  Short term rates are double what they were
in June 2004,  and more than quadruple  where they stood in January 2004.  Since
profit margins (i.e.  spreads) in merger  arbitrage  track short term rates,  we
believe the profit potential in merger arbitrage is considerably greater than it
has been at any time since 2000.

Similarly, though less critically, dealflow is at record levels. In fact, during
the past 12 months we have  witnessed  a  greater  level of merger  transactions
(both in number of  transactions  and dollar  value) than we have seen in half a
decade.  We expect  this trend to  continue  through  the  balance of this year,
driven in large part by globalization  of the world's major  economies.  We say,
however, that record dealflow,  while clearly a boon for arbitrageurs,  is "less
critical"  because  whether or not deal volume  breaks  records or  continues at
current  levels,  The Arbitrage Fund is well positioned to profit from the wider
spreads that result from higher short term interest rates as long as deal volume
remains within historical norms.

It is also worth noting in the current  volatile  market that  mergers  occur in
both  up  markets  and  down  ones  and  that  some  of  the  best   acquisition
opportunities may frequently appear in difficult or volatile markets.

For  these  reasons,  we are  pleased  to  report  to you that  our  predictions
regarding an improved merger arbitrage  environment have proven accurate and our
efforts have borne fruit in the form of improved  returns.  We strongly  believe
that the merger market  remains in the first stage of an extended  recovery both
at home and abroad and that that  recovery  will  continue for several  years to
come.  Record  dealflow  or not, we believe  higher and more  stable  short term
interest  rates  are here to stay,  and that  should  bode  well for the  Fund's
performance.

                               THE ARBITRAGE FUND
                        Notes to the Financial Statements
                                  May 31, 2006
- --------------------------------------------------------------------------------

1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

The Arbitrage  Fund (the "Trust") was organized as a Delaware  business trust on
December 22, 1999 and is registered under the Investment Company Act of 1940, as
amended (the "1940 Act"), as an open-end  management  investment company issuing
its shares in series, each series representing a distinct portfolio with its own
investment  objective and policies.  The one series presently  authorized is The
Arbitrage Fund (the "Fund"), a diversified  series,  which offers two classes of
shares.  Class R shares and Class I shares commenced operations on September 17,
2000 and October 17, 2003, respectively.

The investment objective of the Fund is to achieve capital growth by engaging in
merger arbitrage.

The Fund's two classes of shares,  Class R and Class I,  represent  interests in
the same portfolio of investments and have the same rights, but differ primarily
in the  expenses  to  which  they are  subject  and the  investment  eligibility
requirements.  Class R shares are subject to an annual distribution fee of up to
..25% of the  Fund's  average  daily net assets  attributable  to Class R shares,
whereas Class I shares are not subject to any distribution fees.

The following is a summary of the Fund's significant accounting policies:

USE OF ESTIMATES - The  preparation of financial  statements in conformity  with
accounting  principles  generally  accepted  in the  United  States  of  America
requires  management to make estimates and assumptions  that affect the reported
amounts of assets and  liabilities  at the date of the financial  statements and
the reported  amounts of increases and  decreases in net assets from  operations
during the reporting period. Actual results could differ from those estimates.

VALUATION OF INVESTMENTS - The Fund's portfolio  securities are valued as of the
close of business of the regular session of the New York Stock Exchange ("NYSE")
(normally  4:00  p.m.,  Eastern  time).  Common  stocks  and  other  securities,
including  open short  positions,  that are traded on a securities  exchange are
valued at the last quoted sales price at the close of regular trading on the day
the valuation is made.  Securities  which are quoted by NASDAQ are valued at the
NASDAQ Official Closing Price.  Price information on listed stocks is taken from
the exchange where the security is primarily traded. Securities which are listed
on an exchange but which are not traded on the valuation  date are valued at the
mean of the  most  recent  bid  and  asked  prices.  Put and  call  options  and
securities traded in the  over-the-counter  market are valued at the mean of the
most  recent  bid  and  asked  prices.  Unlisted  securities  for  which  market
quotations  are  readily  available  are valued at the latest  quoted bid price.
Other assets and securities  for which no quotations  are readily  available are
valued at fair value as  determined in good faith under the  supervision  of the
Board of  Trustees  of the  Trust.  Some of the  more  common  reasons  that may
necessitate  that a security  be valued at fair value  include:  the  security's
trading has been halted or  suspended;  the  security has been  delisted  from a
national  exchange;  the

                                                                              20



                               THE ARBITRAGE FUND
                  Notes to the Financial Statements (Continued)
                                  May 31, 2006
- --------------------------------------------------------------------------------

security's  primary  trading market is  temporarily  closed at a time when under
normal conditions it would be open; or the security's  primary pricing source is
not able or willing  to provide a price.  Such  methods  of fair  valuation  may
include,  but are not limited to: multiple of earnings,  multiple of book value,
discount from market of a similar  freely traded  security,  purchase price of a
security, subsequent private transactions in the security or related securities,
or a combination of these and other factors.  Foreign  securities are translated
from the local currency into U.S. dollars using currency exchange rates supplied
by a quotation service (see Note 6).

SHARE  VALUATION  - The net asset value per share of each class of shares of the
Fund is  calculated  daily by  dividing  the total  value of the  Fund's  assets
attributable to that class, less liabilities  attributable to that class, by the
number of shares of that class  outstanding.  The offering  price and redemption
price  per share of each  class of the Fund is equal to the net asset  value per
share,  except that,  shares of each class are subject to a redemption fee of 2%
if redeemed  within 90 days of the date of purchase.  For the year ended May 31,
2006, proceeds from redemption fees were $27,885 in Class R and $147 in Class I.

INVESTMENT  INCOME - Interest  income is accrued as earned.  Dividend income and
expense are recorded on the ex-dividend date.

DIVIDENDS  AND  DISTRIBUTIONS  TO  SHAREHOLDERS  -  Dividends  arising  from net
investment income and net capital gain  distributions,  if any, are declared and
paid at least annually to shareholders of the Fund. The amount of  distributions
from net  investment  income and net realized gains are determined in accordance
with Federal income tax regulations which may differ from accounting  principles
generally accepted in the United States of America. These "book/tax" differences
are either  temporary  or permanent  in nature and are  primarily  due to losses
deferred due to wash sales.

The tax character of distributions  declared during the years ended May 31, 2006
and May 31, 2005 was as follows:

- --------------------------------------------------------------------------------
         Year               Ordinary           Long-Term            Total
        Ended                Income          Capital Gains      Distributions
- --------------------------------------------------------------------------------
       5/31/06           $         --         $        --       $         --
       5/31/05           $ 10,778,315         $ 1,146,281       $ 11,924,596
- --------------------------------------------------------------------------------

ALLOCATION  BETWEEN CLASSES - Investment  income earned,  realized capital gains
and losses, and unrealized  appreciation and depreciation are allocated daily to
each class of shares based upon its proportionate  shares of total net assets of
the Fund.  Class specific  expenses are charged  directly to the class incurring
the expense.  Common expenses which are not attributable to a specific class are
allocated  daily to each class of shares based upon its  proportionate  share of
total net assets of the Fund.

                               THE ARBITRAGE FUND
                  Notes to the Financial Statements (Continued)
                                  May 31, 2006
- --------------------------------------------------------------------------------

SECURITY  TRANSACTIONS - Security  transactions are accounted for on trade date.
Gains and losses on securities sold are determined on a specific  identification
basis.

SHORT  POSITIONS  - The Fund may sell  securities  short  for  economic  hedging
purposes.  For financial statement  purposes,  an amount equal to the settlement
amount is included in the Statement of Assets and Liabilities as an asset and an
equivalent   liability.   The   amount   of  the   liability   is   subsequently
marked-to-market to reflect the current value of the short position.  Subsequent
fluctuations in the market prices of securities sold, but not yet purchased, may
require  purchasing  the  securities  at prices which may differ from the market
value reflected on the Statement of Assets and  Liabilities.  The Fund is liable
for any dividends  payable on securities  while those  securities are in a short
position. As collateral for its short positions,  the Fund is required under the
1940 Act to maintain  assets  consisting  of cash,  cash  equivalents  or liquid
securities.  The amount of the  collateral  is required to be adjusted  daily to
reflect changes in the value of the securities sold short.

WRITTEN OPTION  TRANSACTIONS - The Fund may write (sell) covered call options to
hedge portfolio investments. Put options may also be written by the Fund as part
of a merger arbitrage  strategy  involving a pending  corporate  reorganization.
When the Fund writes (sells) an option,  an amount equal to the premium received
by the Fund is included in the Statement of Assets and  Liabilities  as an asset
and an  equivalent  liability.  The  amount  of the  liability  is  subsequently
marked-to-market  to reflect the current value of the option written. By writing
an  option,  the Fund may  become  obligated  during  the term of the  option to
deliver or purchase the  securities  underlying the option at the exercise price
if the option is  exercised.  Option  contracts are valued at the average of the
current bid and asked price  reported  on the day of  valuation.  When an option
expires on its  stipulated  expiration  date or the Fund  enters  into a closing
purchase  transaction,  the  Fund  realizes  a gain or  loss if the  cost of the
closing purchase  transaction  differs from the premium received when the option
was  sold  without  regard  to any  unrealized  gain or  loss on the  underlying
security, and the liability related to such option is eliminated. When an option
is exercised,  the premium  originally  received decreases the cost basis of the
security (or increases the proceeds on a sale of the security).

EQUITY SWAP CONTRACTS - The Fund may invest in swaps for the purpose of managing
its exposure to interest  rate,  credit or market risk.  An equity swap contract
entitles  the  Fund to  receive  from  the  counterparty  any  appreciation  and
dividends paid on an individual  security,  while obligating the Fund to pay the
counterparty any  depreciation on the security.  Fluctuations in the value of an
open contract are recorded daily as a net unrealized gain or loss. The Fund will
realize a gain or loss upon termination or reset of the contract.  Either party,
under certain  conditions,  may terminate the contract  prior to the  contract's
expiration date. Collateral, in the form of cash or securities,  may be required
to  be  held  in   segregated   accounts  with  the  Fund's   custodian   and/or
counterparty's  broker. Risks may exceed amounts recognized on the Statements 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 swap

                                                                              22

agreements.  Details of swap agreements open at May 31, 2006 are included in the
Fund's Portfolio of Investments and Schedule of Securities Sold Short. As of May
31,  2006,  the Fund had long and short  equity swap  contracts  outstanding  of
$8,746,603 and $865,303, respectively.

FEDERAL  INCOME  TAX - It is the  Fund's  policy  to  comply  with  the  special
provisions of Subchapter M of the Internal  Revenue Code applicable to regulated
investment companies. As provided therein, in any fiscal year in which a Fund so
qualifies and distributes at least 90% of its taxable net income,  the Fund (but
not the  shareholders)  will be  relieved  of  Federal  income tax on the income
distributed. Accordingly, no provision for income taxes has been made.

In  order  to  avoid  imposition  of the  excise  tax  applicable  to  regulated
investment companies, it is also the Fund's intention to declare as dividends in
each calendar year at least 98% of its net investment  income (earned during the
calendar  year) and 98% of its net realized  capital  gains  (earned  during the
twelve months ended October 31) plus undistributed amounts from prior years.

The following information is computed on a tax basis for each item as of May 31,
2006:

- --------------------------------------------------------------------------------
Cost of portfolio investments (including securities sold

- --------------------------------------------------------------------------------

The difference between the Federal income tax cost of portfolio  investments and
the cost reported on the Statement of Assets and  Liabilities  is due to the tax
deferral of losses on wash sales.

For the  fiscal  year  ended  May 31,  2006,  the  fund  utilized  capital  loss
carryforwards of $1,501,235 to offset net realized capital gains.

For the year ended May 31, 2006, the Fund  reclassified net investment losses of
$915,862 and accumulated net realized losses of $258,357 to  paid-in-capital  on
the Statement of Assets and Liabilities.  Such  reclassification,  the result of
permanent  differences  between  financial  statement  and income tax  reporting
requirements  primarily  attributable to  reclassification  of long term capital
gain distributions on Real Estate Investment Trust securities,  gains and losses
on certain  foreign  currency  related  transactions  and net

3.  TRANSACTIONS WITH AFFILIATES

INVESTMENT ADVISORY AGREEMENT
The Fund's investments are managed by Water Island Capital,  LLC (the "Adviser")
under the  terms of an  Investment  Advisory  Agreement.  Under  the  Investment
Advisory  Agreement,  the Fund pays the  Adviser a fee,  which is  computed  and
accrued  daily  and paid  monthly,  at the  annual  rate of 1.50% of the  Fund's
average daily net assets.

Until  August  31,  2012,  the  Adviser  has  contractually  agreed to waive its
advisory fee and/or reimburse the Fund's other expenses to the extent that total
operating expenses (exclusive of interest,  taxes, dividends on short positions,
brokerage  commissions  and other costs incurred in connection with the purchase
or sale of portfolio  securities)  exceed the annual rate of 1.95% of the Fund's
average daily net assets  attributable to Class R shares and 1.70% of the Fund's
average daily net assets  attributable to Class I shares.  Accordingly,  for the
year ended May 31,  2006,  the Adviser  waived  $318,096 of its advisory fee and
reimbursed  the Fund for  $1,740  and  $1,161 of Class R and  Class I  expenses,
respectively.

The Adviser is permitted to recapture fees waived or expenses  reimbursed to the
extent  actual  fees and  expenses  for a  period  are  less  than  the  expense
limitation  of each class,  provided,  however,  that the Adviser  shall only be
entitled to  recapture  such amounts for a period of three years from the end of
the fiscal year during which such amount was waived or reimbursed. As of May 31,
2006,  the  Adviser  may in the future  recapture  from the Fund

                                                                              24

fees waived and expenses  reimbursed totaling $940,941 of which $320,997 expires
May 31, 2009, $397,695 expires May 31, 2008, and $222,249 expires May 31, 2007.

Certain  officers  of the  Trust are also  officers  of the  Adviser.  Effective
October 1, 2004, the Vice President of the Trust also serves as Chief Compliance
Officer  ("CCO") of the Trust and of the Adviser.  The Fund pays the Adviser 15%
of the CCO's salary for providing CCO services.

ADMINISTRATION AGREEMENT

Under the terms of an  Administration  Agreement,  SEI Investments  Global Funds
Services ("SIGFS") supplies  administrative and regulatory services to the Fund,
supervises the  preparation of tax returns,  and  coordinates the preparation of
reports to shareholders and filings with the Securities and Exchange  Commission
and state securities  authorities.  For the performance of these  administrative
services including fund accounting services,  SIGFS receives a monthly fee at an
annual rate of .10% of the Fund's  average  daily net assets up to $500 million;
and .08% of such assets in excess of $500  million,  subject to a minimum fee of

Prior to July 25, 2005,  Ultimus served as the Fund's transfer agent.  For these
services  Ultimus  received from the Fund a monthly fee at an annual rate of $20
per  account,  subject  to a minimum  fee of $1,500  per month for each class of
shares.  For the period June 1, 2005  through  July 24,  2005,  Ultimus was paid
$6,357 under the transfer agent agreement.

Prior  to July  25,  2005,  for  shareholder  accounts  held  through  financial
intermediaries,   Class  I  may  have,   in  some   cases,   compensated   these
intermediaries for providing account maintenance  services to their customers at
an annual  rate of not more than $20 per  account.  For the period  June 1, 2005
through  July 24,  2005,  Class I paid $2,500 to  financial  intermediaries  for
account maintenance services.

FUND ACCOUNTING AGREEMENT

Prior to July 25, 2005, under the terms of a Fund Accounting  Agreement  between
the Trust and Ultimus,  Ultimus  calculated  the daily net asset value per share
and maintained the financial  books and records of the Fund. For these services,
Ultimus received from the Fund a monthly fee of $3,500,  plus an asset based fee
equal to .01% of the  Fund's  average  daily net assets up to $500  million  and
..005% of such  assets  in  excess of $500  million.  Additionally,  on a monthly
basis,  Ultimus  received $5 per trade for  accounting  for portfolio  trades in
excess of two  hundred.  For the  period  June 1, 2005  through  July 24,  2005,
Ultimus was paid $13,975 under the fund accounting agreement.  In addition,  the
Fund reimbursed certain out-of-pocket  expenses incurred by Ultimus in obtaining
valuations of the Fund's portfolio securities.

DISTRIBUTION AGREEMENT

The Fund has  adopted a plan of  distribution  pursuant  to Rule 12b-1 under the
1940 Act (the  "Plan")  for Class R  shares,  which  permits  Class R to pay for
expenses incurred in the distribution and promotion of Class R shares. Under the
Plan,  Class  R  may  pay  compensation  to  any  broker-dealer  with  whom  the
Distributor  or the  Fund,  on  behalf of Class R  shares,  has  entered  into a
contract  to  distribute  Class R shares,  or to any other  qualified  financial
services firm, for distribution and/or shareholder-related services with respect
to shares held or purchased by their respective customers in connection with the
purchase of shares  attributable to their efforts.  The amount of payments under
the Plan in any year shall not exceed .25%  annually  of the  average  daily net
assets allocable to Class R shares. During the year ended May 31, 2006, the Fund
paid Class R distribution expenses of $273,965 pursuant to the Plan.

Under  the  terms  of  a  Distribution  Agreement  between  the  Trust  and  SEI
Investments  Distribution,  Co. (the  "Distributor"),  the Distributor serves as
principal  underwriter and national  distributor for the shares of the Fund. The
Fund's  shares  are sold on a no-load  basis  and,  therefore,  the  Distributor
receives no sales commissions or sales loads for providing services to the Fund.
The Distributor is an affiliate of SEI Investments Global Funds Services.  Prior
to July 25, 2005 Ultimus Fund  Distributors,  LLC served as the Fund's principal
underwriter and distributor.

5.  FOREIGN CURRENCY TRANSLATION

Amounts  denominated  in  or  expected  to  settle  in  foreign  currencies  are
translated to U.S. dollars based on exchange rates on the following basis:

A. The market values of investment  securities and other assets and  liabilities
are translated at the closing rate of exchange each day.

B.  Purchases  and sales of  investment  securities  and income and expenses are
translated at the rate of exchange  prevailing on the  respective  dates of such
transactions.

C. The Fund does not isolate that portion of the results of operations caused by
changes in foreign exchange rates on investments from those caused by changes in
market prices of securities  held. Such  fluctuations  are included with the net
realized and unrealized gains or losses on investments.

Reported net realized  foreign  exchange gains or losses arise from 1) purchases
and sales of foreign  currencies,  2) currency gains or losses realized  between
the trade and settlement dates on securities  transactions and 3) the difference
between  the  amounts of

- --------------------------------------------------------------------------------

dividends,  interest and foreign withholding taxes recorded on the Fund's books,
and the  U.S.  dollar  equivalent  of the  amounts  actually  received  or paid.
Reported net unrealized  foreign exchange gains and losses arise from changes in
the value of assets and liabilities, other than investment securities, resulting
from changes in exchange rates.

6.  CONTINGENCIES AND COMMITMENTS

The Fund indemnifies the Trust's  officers and trustees for certain  liabilities
that  might  arise  from  their   performance  of  their  duties  to  the  Fund.
Additionally,  in the normal  course of business the Fund enters into  contracts
that  contain a variety of  representations  and  warranties  and which  provide
general  indemnifications.  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, based on experience, the Fund expects
the risk of loss to be remote.

7.  SECURITIES LENDING

In order to generate  additional  income,  the Fund may, from time to time, lend
its portfolio securities to broker-dealers,  banks or institutional borrowers of
securities.  The Fund must receive 100%  collateral  in the form of cash or U.S.
government  securities.  This  collateral  must be valued daily and,  should the
market  value of the loaned  securities  increase,  the  borrower  must  furnish
additional  collateral to the Fund. During the time portfolio  securities are on
loan,  the  borrower  pays the  Fund  any  dividends  or  interest  paid on such
securities.  Loans are subject to termination by the Fund or the borrower at any
time.  While the Fund does not have the right to vote securities on loan, it has
the  right  to  terminate  the  loan  and  regain  the  right to vote if that is
considered  important with respect to the investment.  In the event the borrower
defaults in its  obligation to the Fund, the Fund bears the risk of delay in the
recovery  of its  portfolio  securities  and the risk of loss of  rights  in the
collateral. The Fund will only enter into loan arrangements with broker-dealers,
banks or other  institutions  which the Adviser has determined are  creditworthy
under guidelines  established by the Trustees.  There were no securities on loan
as of May 31, 2006.

During the year ended May 31, 2006, the Fund earned $1,778 in securities lending
income.

8.  FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS

The Fund enters into forward  foreign  currency  exchange  contracts as a way of
managing foreign exchange rate risk. The Fund may enter into these contracts for
the purchase or sale of a specific foreign currency at a fixed price on a future
date as a hedge or cross-hedge against either specific transactions or portfolio
positions.  The objective of the Fund's foreign currency hedging transactions is
to reduce risk that the U.S. dollar value of the Fund's  securities  denominated
in foreign  currency  will  decline in value due to changes in


                                                                              28

                                  May 31, 2006
- --------------------------------------------------------------------------------

foreign currency  exchange rates. All foreign  currency  exchange  contracts are
"marked-to  market"  daily at the  applicable  translation  rates  resulting  in
unrealized  gains or losses.  Risks may arise upon entering into these contracts
from the  potential  inability  of  counterparties  to meet  the  terms of their
contracts and from  unanticipated  movements in the value of a foreign  currency
relative to the U.S. dollar.

             Report of Independent Registered Public Accounting Firm
- --------------------------------------------------------------------------------


TO THE BOARD OF TRUSTEES AND SHAREHOLDERS
THE ARBITRAGE FUND

We have  audited the  accompanying  statement of assets and  liabilities  of The
Arbitrage  Fund (the "Fund"),  including the schedules of  investments as of May
31, 2006, and the related  statement of operations for the year then ended,  the
statement  of changes in net assets for each of the two years in the period then
ended,  and the  financial  highlights  for each of the five years in the period
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.

We conducted our audits in accordance  with the standards of the Public  Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material  misstatement.  We were
not engaged to perform an audit of the Trust's  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  Trust's  internal  control  over  financial   reporting.
Accordingly,  we express no such opinion. An audit includes examining, on a test
basis,  evidence  supporting  the  amounts  and  disclosures  in  the  financial
statements.  Our procedures included  confirmation of securities owned as of May
31,  2006 by  correspondence  with the  custodian  and  brokers.  An audit  also
includes assessing the accounting principles used and significant estimates made
by  management,   as  well  as  evaluating  the  overall   financial   statement
presentation.  We believe  that our audits  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
Arbitrage  Fund as of May 31, 2006,  the results of its  operations for the year
then  ended,  the  changes  in its net  assets  for each of the two years in the
period then ended,  and the financial  highlights  for each of the five years in
the period  then ended,  in  conformity  with  accounting  principles  generally
accepted in the United States of America.

                               THE ARBITRAGE FUND
                     About Your Fund's Expenses (Unaudited)
- --------------------------------------------------------------------------------

We believe it is  important  for you to  understand  the impact of costs on your
investment. As a shareholder of a mutual fund, you incur two types of costs: (1)
transaction costs,  including redemption fees; and (2) ongoing costs,  including
management  fees,  distribution  (12b-1)  fees,  and other  fund  expenses.  The
following  examples are intended to help you  understand  your ongoing costs (in
dollars) of  investing  in the Fund and to compare  these costs with the ongoing
costs of investing in other mutual funds.

A mutual  fund's  expenses  are  expressed  as a  percentage  of its average net
assets.  This figure is known as the expense ratio.  The following  examples are
intended to help you  understand  the ongoing costs (in dollars) of investing in
the Fund and to compare these costs with the ongoing costs of investing in other
mutual  funds.  The examples  below are based on an investment of $1,000 made at
the beginning of the period shown and held for the entire period.

The table on the next page illustrates the Fund's costs in two ways:

ACTUAL FUND RETURN - This section helps you to estimate the actual expenses that
you paid over the period.  The "Ending  Account Value" shown is derived from the
Fund's actual return,  and the third column shows the dollar amount of operating
expenses that would have been paid by an investor who started with $1,000 in the
Fund. You may use the information  here,  together with the amount you invested,
to estimate the expenses that you paid over the period.

To do so, simply  divide your account  value by $1,000 (for  example,  an $8,600
account value  divided by $1,000 = 8.6),  then multiply the result by the number
given for the Fund under the heading "Expenses Paid During Period."

HYPOTHETICAL 5% RETURN - This section is intended to help you compare the Fund's
costs with those of other mutual  funds.  It assumes that the Fund had an annual
return of 5% before expenses during the period shown, but that the expense ratio
is  unchanged.  In this case,  because the return used is not the Fund's  actual
return,  the results do not apply to your  investment.  The example is useful in
making comparisons  because the Securities and Exchange  Commission requires all
mutual  funds to  calculate  expenses  based on a 5% return.  You can assess the
Fund's  costs by  comparing  this  hypothetical  example  with the  hypothetical
examples that appear in shareholder reports of other mutual funds.

Note  that  expenses  shown in the table  are  meant to  highlight  and help you
compare  ongoing  costs only.  The Fund does not charge a front-end  sales load.
However,  a redemption fee of 2% is applied on the sale of shares held within 90
days of the date of  purchase  and does not  apply to the  redemption  of shares
acquired through reinvestment of dividends and other distributions.

The  calculations  assume no shares were bought or sold during the period.  Your
actual  costs may have been  higher or lower,  depending  on the  amount of your
investment and the timing of any purchases or redemptions.

More  information  about the Fund's  expenses,  including  annual expense ratios
since  inception,  can be found in this report.  For  additional  information on
operating  expenses  and other  shareholder  costs,  please  refer to the Fund's
prospectus.

                               THE ARBITRAGE FUND
               Trustees' Renewal Of Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

The  Board of  Trustees  (the  "Board")  of The  Arbitrage  Fund  (the  "Fund"),
including a majority of its  independent  Trustees,  approved the continuance of
the Fund's  investment  advisory  agreement with Water Island Capital,  LLC, the
Fund's investment  adviser (hereafter  referred to as the "Adviser").  The board
determined that continuance of the investment advisory agreement was in the best
interests of the Fund and its shareholders.

The Board  based  its  decision  upon its most  recent  review of the  Adviser's
investment personnel,  portfolio management process, and performance.  The Board
discussed the factors below, among others.  However, no single factor determined
whether  the  Board  approved  the  continuation  of  the  investment   advisory
agreement. Rather, it was the totality of the factors that led to the decision.

NATURE, EXTENT, AND QUALITY OF SERVICES

The Board considered the experience of the personnel  managing the Fund's assets
as well as the quality of the Fund's investment  management over both short- and
long-term  periods.  The Board  concluded  the Adviser has provided high quality
consistent service to the Fund and its shareholders.

COST

The Board  considered  the Fund's overall  expense ratio,  comparing it to other
similarly  managed  mutual funds.  In its  consideration  of the Fund's  overall
expense ratio,  the Board also  considered the Adviser's long term commitment to
cap  operating  expenses  by waiving a portion of its  advisory  fee.  The Board
during its review of costs considered the Fund's advisory fee, comparing the fee
to other funds offering similar investment strategies.

The Board  concluded even though the Fund's overall expense ratio is higher than
the average of comparably managed funds, they believe shareholders are receiving
a quality  investment  option for a reasonable  price.  The Board also concluded
that  although the advisory  fees payable to the Adviser are in the higher range
of fees  for  other  comparably  managed  funds,  they  believe  the  fees to be
reasonable  given the  quality  of  services  provided  by the  Adviser  and the
complexity of investment strategies implemented by the Adviser.

PROFITABILITY OF ADVISER

The Board considered the Adviser's  profitability with regards to its management
of the Fund,  concluding that the Adviser's  profitability was not excessive and
therefore was a secondary  factor in connection  with the evaluation of advisory
fees paid by the Fund.



                                                                              34

         Trustees' Renewal Of Advisory Agreement (Unaudited) (Continued)
- --------------------------------------------------------------------------------

INVESTMENT PERFORMANCE

The Board considered the Fund's short- and long-term performance,  including any
periods of outperformance or  underperformance  of relevant  benchmarks and peer
groups.  The Board  concluded  that the Fund has performed  consistent  with its
investment strategy.  The Fund's returns have trailed the average performance of
its peer group as well the broad U.S.  stock  market (as measured by the S&P 500
Index) over the  short-term  (1 year) while  performance  when  measured  over a
longer term (4 + years) has exceeded the average  performance  of its peer group
as well the broad U.S.  stock market.  Information  about the Fund's  historical
performance can be found on page 3 of this Annual Report.

ECONOMIES OF SCALE AND ANCILLARY BENEFITS

The Board concluded that as a result of the significant  decrease in Fund assets
over the past year, at the present time it would not be relevant to consider the
extent to which  economies  of scale would be  realized  as the Fund grows,  and
whether fee levels reflect potential future economies of scale.

The Board also considered the "ancillary benefits" to the Adviser, viewing these
as secondary factors in connection with the evaluation of the  reasonableness of
the  advisory  fees paid by the Fund.  The Board did  consider the level of soft
dollar  activity,  concluding  that as a result of the Fund being the  Adviser's
only client,  benefits  derived from these trades are going directly to the Fund
and its shareholders.
