HATTERAS MULTI-STRATEGY TEI FUND, L.P.

CONSOLIDATED NOTES TO FINANCIAL STATEMENTS - SEPTEMBER 30, 2005 (UNAUDITED)
- --------------------------------------------------------------------------------

1.    ORGANIZATION

      Hatteras  Multi-Strategy  TEI Fund,  L.P (the  "Fund") was  organized as a
      limited partnership under the laws of the State of Delaware on October 29,
      2004. The Fund is registered under the Investment  Company Act of 1940, as
      amended (the "1940 Act"),  as a  closed-end,  non-diversified,  management
      investment  company.  The Fund is designed  for  investment  primarily  by
      tax-exempt and tax-deferred investors.  The Fund's investment objective is
      to generate  consistent  long-term  appreciation  and  returns  across all
      market cycles.  Investors who acquire interests in the Fund  ("Interests")
      are the limited  partners  (each,  a "Limited  Partner" and together,  the
      "Limited  Partners") of the Fund. To achieve its objective,  the Fund will
      provide its limited  partners  with access to a broad range of  investment
      strategies and asset categories, trading advisors ("Advisors") and overall
      asset  allocation  services  typically  available on a collective basis to
      larger  institutions  through an  investment of  substantially  all of its
      assets in the Hatteras Multi-Strategy Offshore Fund, LDC, a Cayman Islands
      limited  duration  company with the same investment  objective as the Fund
      (the "Offshore Fund"). The Offshore Fund will in turn invest substantially
      all of its assets in the Hatteras  Master Fund,  L.P., a Delaware  limited
      partnership  (the "Master Fund"),  which is also registered under the 1940
      Act.

      The Master  Fund is  managed by  Hatteras  Investment  Partners,  LLC (the
      "Investment  Manager"), a Delaware limited liability company registered as
      an  investment  adviser  under the  Investment  Advisers  Act of 1940,  as
      amended.  The Offshore  Fund will serve solely as an  intermediate  entity
      through  which the Fund will invest in the Master Fund.  The Offshore Fund
      will make no  independent  investment  decisions  and has no investment or
      other  discretion  over the investable  assets.  The Fund and the Offshore
      Fund both commenced operations on April 1, 2005.

      The Fund owns 100% of the  beneficial  interests of the Offshore Fund, and
      the  Offshore  Fund owns 5.55% of the  beneficial  interests in the Master
      Fund.  These financials  statements are the  consolidation of the Fund and
      the Offshore Fund.  Inter company  balances have been  eliminated  through
      consolidation.

      Hatteras Investment Management, LLC, a Delaware limited liability company,
      serves as the General Partner of the Fund ("General Partner"). The General
      Partner has appointed a Board of Directors  ("Board")  and, to the fullest
      extent permitted by applicable law, has irrevocably delegated to the Board
      its rights and powers to monitor and oversee the  business  affairs of the
      Fund,  including  the  complete  and  exclusive  authority  to oversee and
      establish policies regarding the management,  conduct and operation of the
      Fund's business.

2.    SIGNIFICANT ACCOUNTING POLICIES

      These   financial   statements  have  been  prepared  in  accordance  with
      accounting  principles  generally accepted in the United States of America
      and are expressed in United States dollars.  The following is a summary of
      significant  accounting  and  reporting  policies  used in  preparing  the
      financial statements.

(CONTINUED)
- --------------------------------------------------------------------------------

2.    SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

      A.    VALUATION

      Valuation  of the  Fund's  interest  in the  Master  Fund is  based on the
      investment in underlying  securities  held by the Master Fund.  The Master
      Fund will value interests in the Underlying  Funds (as defined in attached
      Master Fund financial  statements) at fair value, which ordinarily will be
      the  value  determined  by  their  respective   investment  managers,   in
      accordance  with  procedures  established  by the  Board.  Investments  in
      Underlying  Funds  are  subject  to the  terms  of the  Underlying  Funds'
      offering  documents.  Valuations of the Underlying Funds may be subject to
      estimates  and are net of management  and  performance  incentive  fees or
      allocations  payable to the Underlying  Funds' managers as required by the
      Underlying Funds' offering documents.  Because of the inherent uncertainty
      in valuation,  the estimated  values may differ from the values that would
      have been  used had a ready  market  for the  securities  existed  and the
      differences could be material. The accounting policies of the Master Fund,
      including  the  valuation  of  securities  held by the Master  Fund,  will
      directly  affect  the Fund and are  discussed  in the  Notes to  Financial
      Statements of the Master Fund which are attached to this report.

      B.    ALLOCATION FROM MASTER FUND

      As  required by  accounting  principles  generally  accepted in the United
      States of  America,  the Fund  records  its  allocated  portion of income,
      expense,  realized gains and losses and  unrealized  gains and losses from
      the Master Fund.

      C.    FUND LEVEL INCOME AND EXPENSES

      Interest  income  on any cash or cash  equivalents  held by a Fund and not
      invested  into the Master Fund will be  recognized  on the accrual  basis.
      Expenses that are  specifically  attributed to the Fund are charged to the
      Fund. The Fund will also bear, as an investor in the Master Fund,  through
      its investment in the Offshore Fund, its allocable portion of the fees and
      expenses of the Master Fund and the Offshore Fund.  Because the Fund bears
      its  proportionate  share of the  management  fees of the Master Fund, the
      Fund does not pay any additional  compensation  directly to the Investment
      Manager.

      In  accordance  with  the  Private  Placement  Memorandum,   the  Fund  is
      amortizing   organizational   expenses  over  a  sixty-month  period.  For
      financial  statement   purposes,   in  order  to  comply  with  accounting
      principles  generally  accepted in the United States of America,  the Fund
      expensed the  unamortized  amount of  organizational  expenses  during the
      current period.

      D.    TAX BASIS REPORTING

      Because the Master Fund  invests  primarily in  investment  funds that are
      treated as partnerships for U.S.  Federal tax purposes,  the tax character
      of the Fund's  allocated  earnings is  established  dependent upon the tax
      filings of the investor partnerships.  Accordingly, the tax basis of these
      allocated  earnings and the related  balances are not  available as of the
      reporting date.

2.    SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

      E.    CASH AND CASH EQUIVALENTS

      Cash  and cash  equivalents  includes  amounts  held in  interest  bearing
      overnight  accounts.  At September 30, 2005,  the Fund held $128,178 in an
      interest bearing cash account at PNC Bank.

      F.    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 and disclosure of contingent  assets and
      liabilities  at the date of the  financial  statements,  and the  reported
      amounts of income and expenses during the reported period.  Actual results
      could differ from those estimates.

3.    ALLOCATION OF LIMITED PARTNERS' CAPITAL ACCOUNT

      Net  profits  or net  losses  of  the  Fund  for  each  Allocation  Period
      ("Allocation  Period") will be allocated  among and credited to or debited
      against the capital accounts of the Limited  Partners.  Net profits or net
      losses  will be  measured as the net change in the value of the net assets
      of the Fund,  including  any net  change  in  unrealized  appreciation  or
      depreciation  of investments  and realized  income and gains or losses and
      expenses (including private placement and organizational  expenses) during
      an allocation period,  adjusted to exclude any items to be allocated among
      the capital accounts of the Limited Partners other than in accordance with
      the Limited Partners' respective investment percentages.

      Allocation  Periods  begin on the day after the last day of the  preceding
      Allocation  Period and end at the close of business on (1) the last day of
      each month;  (2) the last day of each taxable year;  (3) the day preceding
      each day on which interests are purchased;  (4) the day on which interests
      are  repurchased;  or (5) the day on which any  amount is  credited  to or
      debited  from the  capital  account of any Limited  Partner  other than an
      amount to be  credited  to or debited  from the  capital  accounts  of all
      limited   partners  in  accordance   with  their   respective   investment
      percentages in the Master Fund.

      The Fund will maintain a separate capital account  ("Capital  Account") on
      its books for each Limited Partner. Each Limited Partner's capital account
      will  have an  opening  balance  equal to the  Limited  Partner's  initial
      contribution  to  the  capital  of  the  Fund  (i.e.,  the  amount  of the
      investment less any applicable  sales load),  and thereafter,  will be (i)
      increased by the amount of any additional  capital  contributions  by such
      Limited  Partner;  (ii)  decreased for any payments upon  repurchase or in
      redemption  of such Limited  Partner's  Interest or any  distributions  in
      respect of such Limited  Partner;  and (iii)  increased or decreased as of
      the close of each Allocation  Period by such Limited  Partner's  allocable
      share of the net profits or net losses of the Fund.

4.    RELATED PARTY TRANSACTIONS AND OTHER

      In  consideration  for  investor  services,  the Fund  will  pay  Hatteras
      Investment  Partners,  LLC (in such capacity,  the  "Servicing  Agent") an
      investor  servicing fee at the annual rate of 0.75% of the net asset value
      of the Interests beneficially owned by customers of the Servicing Agent or
      any service  provider  who has entered into a service  provider  agreement
      with the  Servicing  Agent.  The  investor  servicing  fees payable to the
      Servicing  Agent will be borne by all  Partners of the Fund pro rata.  The
      Servicing Agent may waive (to all investors on a pro-rata basis) or pay to
      third parties all or a portion of any such fees in its sole discretion.

      The Fund paid a Servicing  Fee for the period  April 1, 2005  through June
      30, 2005,  based on the net asset value of all Partners'  Capital Accounts
      as of the first  business day of each fiscal  quarter.  Effective  July 1,
      2005,  the  Servicing  Fee  computation  has been changed to the aggregate
      value of outstanding Interests held by Limited Partners of the Fund on the
      last day of the month  (before  repurchase  of  Interests  or  performance
      allocation).

      The  General  Partner  generally  receives  an  annual  performance  based
      allocation  (the  "Performance  Allocation")  with  respect to the Capital
      Account of each Limited Partner. The Performance  Allocation is calculated
      generally as of the end of each calendar year. The Performance  Allocation
      with respect to a Limited Partner's Capital Account is equal to 10% of the
      amount by which the excess,  if any, of net profit over net loss allocated
      to such  Limited  Partner  for the  calendar  year  exceeds  (a) any  Loss
      Carryforward  Amount (as defined below) for such Limited  Partner plus (b)
      the  non-cumulative  "hurdle amount" (an annualized  return on the Capital
      Account  balance  of  such  Limited  Partner  as of  the  last  day of the
      preceding  calendar  year at a rate equal to the yield to  maturity of the
      90-day United States  Treasury Bill as reported by the Wall Street Journal
      on  the  last  day  of  the  preceding  calendar  year).  The  Performance
      Allocation  with  respect to each  applicable  Limited  Partner's  Capital
      Account shall be deducted  from such Capital  Account and allocated to the
      Capital  Account of the  General  Partner.  If at the end of any  calendar
      year,  the Net Losses  allocated to a Limited  Partner's  Capital  Account
      exceed the Net Profits so allocated, then a Loss Carryforward Amount shall
      be established for that Limited Partner.  No Performance  Allocation shall
      be deducted  from the Capital  Account of any Limited  Partner  unless the
      excess of Net Profits over Net Losses  subsequently  allocated exceeds any
      Loss  Carryforward  Amount for that Limited Partner.  If a Limited Partner
      withdraws  completely  from the Fund  other  than at the end of a calendar
      year, a Performance  Allocation shall be made with respect to such Limited
      Partner's Capital Account as of the date of complete withdrawal as if such
      date were the end of a  calendar  year and the hurdle  amount  will be pro
      rated.

      PFPC Inc. serves as administrator, accounting and investor servicing agent
      to the Fund and provides certain  accounting,  recordkeeping  and investor
      related services. PFPC Trust Co. provides custodial services to the Fund.

5.    FEDERAL INCOME TAXES

      For federal income tax purposes, the Fund is treated as a partnership, and
      each  limited  partner  in  the  Fund  is  treated  as  the  owner  of its
      proportionate share of the net assets, income,  expenses, and the realized
      and unrealized gains (losses) of the Fund. Accordingly,  no federal, state
      or local income


                                       8


HATTERAS MULTI-STRATEGY TEI FUND, L.P.

CONSOLIDATED NOTES TO FINANCIAL STATEMENTS - SEPTEMBER 30, 2005 (UNAUDITED)
(CONTINUED)
- --------------------------------------------------------------------------------

5.    FEDERAL INCOME TAXES (CONTINUED)

      taxes have been  provided  on profits of the Fund since the  partners  are
      individually liable for the taxes on their share of the Fund's income.

6.    RISK FACTORS

      An  investment  in the Fund  involves  significant  risks  that  should be
      carefully  considered prior to investment and should only be considered by
      persons financially able to maintain their investment and who can afford a
      loss of a  substantial  part or all of such  investment.  The Master  Fund
      intends to invest substantially all of its available capital in securities
      of private  investment  companies.  These  investments  will  generally be
      restricted  securities that are subject to substantial  holding periods or
      are not traded in public  markets at all,  so that the Master Fund may not
      be able to resell some of its  securities  holdings for extended  periods,
      which may be several years.  No guarantee or  representation  is made that
      the investment objective will be met.

7.    REPURCHASE OF PARTNERS' INTERESTS

      The Fund intends to conduct quarterly repurchase offers for the redemption
      of the Interests at their net asset value  determined as of  approximately
      March 31, June 30,  September 30 and December 31 of each year beginning on
      March 31, 2006 (each such date, a "Valuation Date"). A Limited Partner may
      participate  in a  repurchase  offer only after 12  consecutive  months as
      Limited  Partner in the Fund.  However,  the General  Partner  retains the
      discretion to approve such redemption offers and, therefore,  there are no
      assurances that the General Partner will, in fact, decide to undertake any
      repurchase offer. The General Partner may also permit repurchases at other
      times,  in its sole  discretion.  A Limited  Partner may  participate in a
      repurchase  offer only after 12 consecutive  months as Limited  Partner in
      the Fund.  The Fund's  assets  consist  primarily  of its  interest in the
      Master  Fund  (held  through  its   investment  in  the  Offshore   Fund).
      Accordingly,  the Fund will be  required  to  liquidate  a portion  of its
      interest  in the  Master  Fund in order to fund  repurchases.  In order to
      liquidate  its  interest in the Master Fund,  the Offshore  Fund (which is
      effectively  controlled by the Fund's Board) must accept repurchase offers
      made by the Master Fund and distribute the proceeds of such repurchases to
      the Fund.

      The Fund does not intend to distribute to the Limited  Partners any of the
      Fund's income, but intends to reinvest  substantially all income and gains
      allocable  to the Limited  Partners.  A Limited  Partner may  therefore be
      allocated taxable income and gains and not receive any cash distribution.

8.    GUARANTEES

      In the normal  course of  business,  the Fund enters into  contracts  that
      provide general indemnifications.  The Fund's maximum exposure under these
      agreements  is  dependent  on future  claims that may be made  against the
      Fund, and therefore cannot be established;  however,  based on experience,
      the risk of loss from such claims is considered remote.

9.    CONSOLIDATED FINANCIAL HIGHLIGHTS

      The financial  highlights  are intended to help you  understand the Fund's
      financial  performance for the past period. The total returns in the table
      represent the rate that a Limited  Partner would have earned or lost on an
      investment in the Fund.

      The ratios and total return  amounts are  calculated  based on the Limited
      Partner group taken as a whole.  The General Partner  interest is excluded
      from the calculations.  Individual Limited Partner's ratios or returns may
      vary from the table below based on incentive  arrangements  and the timing
      of capital transactions.

      The ratios are  calculated by dividing total dollars of income or expenses
      as applicable by the average of total monthly Limited Partner capital. The
      ratios include the Fund's  proportionate share of the Master Fund's income
      and expenses.

      Total return amounts are calculated by geometrically linking returns based
      on the change in value  during each  accounting  period.  The total return
      amounts have not been annualized.



                                                                                            PERIOD FROM

NOTES TO FINANCIAL STATEMENTS - SEPTEMBER 30, 2005 (UNAUDITED)
- --------------------------------------------------------------------------------

1.   ORGANIZATION

      Hatteras  Master Fund, L.P. (the "Master Fund") was organized as a limited
      partnership  under the laws of the State of Delaware on October 29,  2004.
      The Master Fund is registered under the Investment Company Act of 1940, as
      amended  (the "1940 Act"),  as a  closed-end,  non-diversified  management
      investment  company.  The Master  Fund is managed by  Hatteras  Investment
      Partners LLC (the  "Investment  Manager"),  a Delaware  limited  liability
      company registered as an investment adviser under the Investment  Advisers
      Act of 1940,  as amended.  The objective of the Master Fund is to generate
      consistent long-term appreciation and returns across all market cycles. To
      achieve its objective,  the Master Fund will provide its limited  partners
      (each, a "Partner" and together,  the  "Partners")  with access to a broad
      range of investment  strategies  and asset  categories,  trading  advisors
      ("Advisors") and overall asset allocation  services typically available on
      a  collective  basis to larger  institutions.  Generally,  the  Investment
      Manager  intends  to  select  Advisors  that  collectively  employ  widely
      diversified  investment  strategies  and  engage  in  such  techniques  as
      Opportunistic  Equity,  Enhanced Fixed Income,  Absolute  Return,  Private
      Equity, Real Estate and Energy/Natural Resources.  However, the Investment
      Manager may also retain Advisors who utilize other strategies.  The Master
      Fund  invests  with each Advisor  either by becoming a  participant  in an
      investment  vehicle  operated by the Advisor (an "Underlying  Fund") or by
      placing asset in an account  directly  managed by the Advisor.  The Master
      Fund  commenced  operations on January 3, 2005.  Prior to January 3, 2005,
      the Master Fund  engaged in no  transactions  other than those  related to
      organizational  matters  and the sale of a $100,000  interest  to Hatteras
      Diversified Strategies Fund, LP.

      Hatteras Investment  Management LLC, a Delaware limited liability company,
      serves as the General Partner of the Master Fund ("General Partner").  The
      General  Partner has  initially  appointed a Board of Directors  ("Board")
      and, to the fullest extent  permitted by applicable  law, has  irrevocably
      delegated  to the Board its rights and powers to monitor  and  oversee the
      business affairs of the Master Fund,  including the complete and exclusive
      authority to oversee and  establish  policies  regarding  the  management,
      conduct and operation of the Master Fund's business.

      On January 1,  2005,  the Fund  received  capital  contributions  totaling
      $116,269,458, including contributions in the form of transfer-in-kind from
      Hatteras   Diversified   Strategies  Fund,  LP  and  Hatteras  Diversified
      Strategies   Offshore  Fund,  Ltd.  for   $72,386,769   and   $16,620,182,
      respectively.  In addition,  the Hatteras Diversified  Strategies Offshore
      Fund,  Ltd.  transferred  receivables  in the  amount of  $17,242,388  and
      liquidated  $10,020,119 of the Fund's  securities at December 31, 2004 and
      reinvested the proceeds in the Master Fund.

2.    SIGNIFICANT ACCOUNTING POLICIES

      These   financial   statements  have  been  prepared  in  accordance  with
      accounting  principles  generally accepted in the United States of America
      and are expressed in United States dollars.  The following is a summary of

      required by the Underlying  Funds' offering  documents.  If the Investment
      Manager  determines  that the most recent value reported by the Underlying
      Fund does not  represent  fair  value or if the  Underlying  Fund fails to
      report a value to the  Master  Fund,  a fair value  determination  is made
      under procedures  established by and under the general  supervision of the
      Board.  Because of the inherent  uncertainty  in valuation,  the estimated
      values  may differ  from the values  that would have been used had a ready
      market for the securities existed, and the differences could be material.

      B.    INVESTMENT INCOME

      Interest  income is recorded on the accrual basis.  The  Underlying  Funds
      generally do not make regular cash  distributions  of income and gains and
      so are generally considered non-income producing  securities,  however the
      Master Fund owns two  securities  that are income  producing  and disburse
      regular cash distributions.

      C.    FUND EXPENSES

      The Master Fund will bear all  expenses  incurred  in the  business of the
      Master Fund, including,  but not limited to, the following:  all costs and
      expenses  related to portfolio  transactions  and positions for the Master
      Fund's  account;  legal  fees;  accounting  and  auditing  fees;  costs of
      insurance; registration expenses; certain offering and organization costs;
      and expenses of meetings of the Board.

      In accordance with the Private  Placement  Memorandum,  the Master Fund is
      amortizing   organizational   expenses  over  a  sixty-month  period.  For
      financial  statement   purposes,   in  order  to  comply  with  accounting
      principles  generally  accepted in the United States of America,  the Fund
      expensed the  unamortized  amount of  organizational  expenses  during the
      current period.

      D.    INCOME TAXES

      The  Master  Fund is  treated  as a  partnership  for  federal  income tax
      purposes and therefore  not subject to federal  income tax. For income tax
      purposes,  the individual  partners will be taxed upon their  distributive
      share of each item of the Master Fund's income, gain, loss, deductions and
      credits.

2.    SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

      E.    CASH AND CASH EQUIVALENTS

      Cash  and cash  equivalents  includes  amounts  held in  interest  bearing
      overnight accounts. At September 30, 2005, the Master Fund held $2,084,325
      in an interest bearing cash account at PNC Bank.

      F.    USE OF ESTIMATES

      The  preparation  of financial  statements in conformity  with  accounting
      principles generally accepted in the United States of America requires the
      Master Fund 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 income  and  expense  during  the  reporting
      period. Actual results could differ from these estimates.

3.    ALLOCATION OF PARTNERS' CAPITAL ACCOUNT

      Net  profits or net losses of the Master Fund for each  Allocation  Period
      (as defined  below)  will be  allocated  among and  credited to or debited
      against the capital accounts of the Partners.  Allocation Periods begin on
      the day after the last day of the preceding  Allocation  Period and end at
      the close of business on (1) the last day of each month,  (2) the last day
      of each taxable year;  (3) the day preceding  each day on which  interests
      are purchased, (4) the day on which interests are repurchased,  or (5) the
      day on which any amount is credited to or debited from the capital account
      of any Partner  other than an amount to be credited to or debited from the
      capital  accounts of all  Partners  in  accordance  with their  respective
      investment percentages.

4.    MANAGEMENT FEE, RELATED PARTY TRANSACTIONS AND OTHER

      The Investment Manager is responsible for providing day-to-day  investment
      management   services  to  the  Master  Fund,   subject  to  the  ultimate
      supervision  of and  subject  to any  policies  established  by the Board,
      pursuant  to the  terms of an  investment  management  agreement  with the
      Master Fund (the "Investment Management Agreement").  Under the Investment
      Management   Agreement,   the  Investment   Manager  is  responsible   for
      developing, implementing and supervising the Fund's investment program.

      In  consideration  for such services,  the Master Fund pays the Investment
      Manager a  monthly  management  fee equal to 1/12th of 1.00%  (1.00% on an
      annualized  basis) of the aggregate value of its net assets  determined as
      of the last day of the month (before  repurchase of  interests).  Prior to
      July 1, 2005, the Master Fund paid a management fee based on the net asset
      value as of the first business day of each fiscal quarter.

4.    MANAGEMENT FEE, RELATED PARTY TRANSACTIONS AND OTHER (CONTINUED)

      Each member of the Board who is not an  "interested  person" of the Master
      Fund, as defined by the 1940 Act ("Independent Board"), receives an annual
      retainer of $10,000.  All Board members are  reimbursed by the Master Fund
      for all reasonable  out-of-pocket  expenses incurred by them in performing
      their duties.

      PFPC Trust  Company  serves as custodian of the Master  Fund's  assets and
      provides  custodial  services  for the Master  Fund.  PFPC Inc.  serves as
      administrator and accounting agent to the Master Fund and provides certain
      accounting,  record keeping and investor related services. The Master Fund
      pays a monthly  fee to the  administrator  based  upon  average  partners'
      capital, subject to certain minimums.

5.    INVESTMENT TRANSACTIONS

      Total purchases of Underlying Funds for the six months ended September 30,
      2005,  amounted to  $25,198,536.  Total  proceeds from sales of Underlying
      Funds for the six months ended September 30, 2005, amounted to $4,225,920.
      The cost of  investments  in  Underlying  Funds  for  Federal  income  tax
      purposes is adjusted for items of taxable  income  allocated to the Master
      Fund  from  the  Underlying  Funds.  The  Master  Fund  has  not  received
      information  from the Underlying Funds as to the amounts of taxable income
      allocated to the Master Fund as of September 30, 2005.

6.    UNDERLYING FUNDS

      The  following  is a summary of the  investment  objective  and  liquidity
      provisions of the  Underlying  Funds that exceeded 5% of the Master Fund's
      net assets at September 30, 2005.

      Contrarian  Capital Fund I, L.P.  seeks to maximize  total return  through
      investment   in  a  broad  based   distressed   securities   portfolio  of
      predominantly  U.S.  corporate  obligations and, to a lesser extent,  real
      estate and non-U.S.  restructurings.  The Uunderlying Fund may also invest
      up to 20% of its assets in securities  for which there is no ready market.
      The Underlying  Fund allows for redemptions as of the last business day of
      any fiscal  year on a 90 day  written  notice,  after one fiscal  year has
      elapsed.

7.    RISK FACTORS

      An investment in the Master Fund involves significant risks that should be
      carefully  considered  prior to investing and should only be considered by
      persons financially able to maintain their investment and who can afford a
      loss of a  substantial  part or all of such  investment.  The Master  Fund
      intends to invest substantially all of its available capital in securities
      of private  investment  companies.  These  investments  will  generally be
      restricted  securities that are subject to substantial  holding periods or
      are not traded in public  markets at all,  so that the Master Fund may not
      be able to resell some of its  securities  holdings for extended  periods,
      which may be several years.  No guarantee or  representation  is made that
      the investment objective will be met.

NOTES TO FINANCIAL STATEMENTS - SEPTEMBER 30, 2005 (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

8.    REPURCHASE OF PARTNERS' INTERESTS

      The Board  may,  from time to time and in its sole  discretion,  cause the
      Master Fund to  repurchase  interests  from  Partners  pursuant to written
      tenders by  Partners  at such times and on such  terms and  conditions  as
      established by the Board.  In  determining  whether the Master Fund should
      offer to repurchase interests,  the Board will consider the recommendation
      of the Investment  Manager.  The Investment  Manager  expects that it will
      generally  recommend to the Board that the Master Fund offer to repurchase
      interests from Partners  quarterly as of approximately  March 31, June 30,
      September 30 and December 31 of each year beginning on March 31, 2006.

      The Master Fund does not intend to  distribute  to the Partners any of the
      Master Fund's income, but intends to reinvest substantially all income and
      gains  allocable  to the  Partners.  A Partner may  therefore be allocated
      taxable income and gains and not receive any cash distribution.

9.    GUARANTEES

      In the normal  course of business,  the Master Fund enters into  contracts
      that provide general indemnifications.  The Master Fund's maximum exposure
      under these  agreements  is  dependent  on future  claims that may be made
      against the Master Fund,  and therefore  cannot be  established;  however,
      based on  experience,  the risk of loss  from such  claims  is  considered
      remote.

10.   COMMITMENTS

      As of  September  30,  2005,  the Master Fund had  outstanding  investment
      commitments to Underlying Funds totaling $11,292,891.

11.   FINANCIAL HIGHLIGHT INFORMATION

      The financial  highlights  are intended to help you  understand the Master
      Fund's financial performance for the past period. The total returns in the
      table represent the rate that limited partner would have earned or lost on
      an investment in the Master Fund.

      The ratios and total return  amounts are  calculated  based on the limited
      partner group taken as a whole.  The General Partner  interest is excluded
      from the  calculations.  An individual  limited partner's results may vary
      from those shown below due to the timing of capital transactions.

      The ratios are  calculated by dividing total dollars of income or expenses
      as applicable by the average of total monthly limited partner capital. The
      ratios do not reflect the Master Fund's  proportionate share of income and
      expenses from Underlying Funds.

      Total return amounts are calculated by geometrically linking returns based
      on the change in value  during each  accounting  period.  The total return
      amounts have not been annualized.
