HATTERAS FUNDS

NOTES TO FINANCIAL STATEMENTS

September 30, 2009 (Unaudited)

1. ORGANIZATION

The Hatteras Funds, each a “Feeder Fund” and collectively the “Feeder Funds” are:

Hatteras Multi-Strategy Fund, L.P.

Hatteras Multi-Strategy TEI Fund, L.P.

Hatteras Multi-Strategy Institutional Fund, L.P.

Hatteras Multi-Strategy TEI Institutional Fund, L.P.

The Hatteras Multi-Strategy TEI Fund, L.P. and the Hatteras Multi-Strategy TEI Institutional Fund, L.P. each invest substantially all of their assets in the Hatteras Multi-Strategy Offshore Fund, LDC, and Hatteras Multi-Strategy Offshore Institutional Fund, LDC, (collectively the “Blocker Funds”), respectively. The Blocker Funds are Cayman Islands limited duration companies with the same investment objective as the Feeder Funds. The Blocker Funds serve solely as intermediate entities through which the Multi-Strategy TEI Fund, L.P. and the Hatteras Multi-Strategy TEI Institutional Fund, L.P. invest in Hatteras Master Fund, L.P. (the “Master Fund” and together with the Feeder Funds, the “Funds”). The Blocker Funds enable tax-exempt Limited Partners (as defined below) to invest without receiving certain income in a form that would otherwise be taxable to such tax-exempt Limited Partners regardless of their tax-exempt status. The Multi-Strategy TEI Fund, L.P. owns 100% of the participating beneficial interests of the Hatteras Multi-Strategy Offshore Fund, LDC and the Multi-Strategy TEI Institutional Fund, L.P. owns 100% of the participating beneficial interests of the Hatteras Multi-Strategy Offshore Institutional Fund, LDC. Where these Notes to Financial Statements discuss the Feeder Funds’ investment in the Master Fund, for Hatteras Multi-Strategy TEI Fund, L.P. and Hatteras Multi-Strategy TEI Institutional Fund, L.P., it means their investment in the Master Fund through the applicable Blocker Fund.

Each of the Feeder Funds are organized as Delaware limited partnerships, and registered under the Securities Act of 1933, as amended, and the Investment Company Act of 1940, as amended, (the “1940 Act”) as closed-end, non-diversified, management investment companies. The investment objective of the Feeder Funds is to provide capital appreciation consistent with the return characteristic of the alternative investment portfolios of larger endowments through investments in the six asset classes of Opportunistic Equity, Enhanced Fixed Income, Absolute Return, Real Estate, Private Equity and Energy and Natural Resources. The Funds’ secondary objective is to provide capital appreciation with less volatility than that of the equity markets. To achieve their objective, the Feeder Funds provide their investors with access to a broad range of investment strategies, asset categories and trading advisers (“Advisers”) and by providing overall asset allocation services typically available on a collective basis to larger institutions, through an investment of substantially all of their assets into the Master Fund, which is 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. Investors who acquire units of limited partnership interest in the Feeder Funds (“Units”) are the limited partners (each, a “Limited Partner” and together, the “Limited Partners”) of the Feeder Funds.

The percentage of the Master Fund’s beneficial limited partnership interests owned by the Feeder Funds at September 30, 2009 were:

Hatteras Multi-Strategy Fund, L.P.	17.35%
Hatteras Multi-Strategy TEI Fund, L.P.	21.26%
Hatteras Multi-Strategy Institutional Fund, L.P.	38.25%
Hatteras Multi-Strategy TEI Institutional Fund, L.P.	18.57%

NOTES TO FINANCIAL STATEMENTS

September 30, 2009 (Unaudited) (continued)

1. ORGANIZATION (CONTINUED)

Hatteras Investment Management, LLC, a Delaware limited liability company, serves as the General Partner of each of the Funds (“General Partner”). The General Partner is an affiliate of the Investment Manager. The General Partner has appointed a Board of Directors for each Fund (collectively the “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 Funds, including the complete and exclusive authority to oversee and establish policies regarding the management, conduct and operation of the Feeder Funds’ business.

2. SIGNIFICANT ACCOUNTING POLICIES

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

a. Investment Valuation

The Feeder Funds record their investment in the Master Fund at fair value. Valuation of securities held by the Master Fund is discussed in the notes to the Master Fund’s financial statements included elsewhere in this report.

The accounting policies of the Master Fund, including the valuation of the Master Fund’s investment in a wide range of investment vehicles (“Adviser Funds”) managed by Advisers or the assets placed in accounts directly managed by the Adviser, will directly affect the Feeder Funds and are discussed in the Notes to Financial Statements of the Master Fund, which are included elsewhere in this report. The Feeder Funds do not make direct investments in securities or financial instruments, and invest substantially all of their assets in the Master Fund. The additional disclosures required by authoritative accounting guidance are included in the notes to the financial statements of the Master Fund, which are included elsewhere in this report.

b. Allocations from the Master Fund

The Feeder Funds record their allocated portion of income, expense, realized gains and losses and unrealized appreciation and depreciation from the Master Fund.

c. Fund Level Income and Expenses

Interest income on any cash or cash equivalents held by the Feeder Funds will be recognized on an accrual basis. Expenses that are specifically attributed to the Feeder Funds are charged to each Feeder Fund. Because the Feeder Funds bear their proportionate share of the management fees of the Master Fund, the Feeder Funds pay no direct management fee to the Investment Manager. Income and expenses are recorded on an accrual basis.

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 each of the Feeder Fund’s allocated earnings is established dependent upon the tax filings of the Adviser Funds. 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. Income Taxes

For U.S. Federal income tax purposes, the Feeder Funds are treated as partnerships, and each Limited Partner in the Feeder Funds is treated as the owner of its proportionate share of the net assets, income, expenses, and the realized and unrealized gains (losses) of the Feeder Fund. Accordingly, no federal, state or local income taxes have been provided on profits of the Feeder Funds since the Limited Partners are individually liable for the taxes on their share of the Feeder Funds.

The Fund has reviewed any potential tax positions as of September 30, 2009 and has determined that it does not have a liability for any unrecognized tax benefits. During the period ended September 30, 2009, the Feeder Funds did not incur any material interest or penalties. For returns filed for the years ended December 31, 2005 through December 31, 2008 the Feeder Funds are open to examination by U.S. federal tax authorities and state tax authorities.

f. Cash and Cash Equivalents

Cash and cash equivalents includes amounts held in interest-bearing demand deposit accounts.

Such cash, at times, may exceed federally insured limits. The Feeder Funds have not experienced any losses in such accounts and do not believe they are exposed to any significant credit risk on such accounts.

g. Use of Estimates

The preparation of financial statements in conformity with GAAP 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 increases and decreases in Limited Partners’ capital from operations during the reporting period. Actual results could differ from those estimates.

h. Recently Issued Accounting Pronouncements

Authoritative accounting guidance requires disclosures about the reporting entity’s derivative instruments and hedging activities, by providing for qualitative disclosures about the objectives and strategies for using derivatives, quantitative data about the fair value of and gains and losses on derivative contracts, and details of credit-risk-related contingent features in their hedged positions. As of September 30, 2009, the Feeder Funds had not entered into any derivative instruments.

3. ALLOCATION OF LIMITED PARTNERS’ CAPITAL

Net profits or net losses of the Feeder Funds 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 Limited Partners’ capital of the Feeder Funds, including any net change in unrealized appreciation or depreciation of investments and realized income and gains or losses and expenses during an allocation period, adjusted to exclude any items to be allocated among the capital accounts of the Limited Partners in accordance with the Limited Partners’ respective investment percentages.

3. ALLOCATION OF LIMITED PARTNERS’ CAPITAL (CONTINUED)

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 Feeder Funds maintain a separate capital account (“Capital Account”) on their 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 Feeder Fund (i.e., the amount of the investment less any applicable sales load of up to 2 percent of the contribution amount), 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 Feeder Fund.

4. RELATED PARTY TRANSACTIONS AND OTHER

In consideration for fund services, Hatteras Multi-Strategy Fund, L.P., Hatteras Multi-Strategy TEI Fund, L.P., Hatteras Multi-Strategy Institutional Fund L.P., and Hatteras Multi-Strategy TEI Institutional Fund, L.P., will pay the Investment Manager (in such capacity, the “Servicing Agent”) a fund servicing fee at the annual rate of 0.85%, 0.85%, 0.10% and 0.10%, respectively, of the month-end net asset value of the applicable Feeder Fund. The Feeder Fund servicing fees payable to the Servicing Agent will be borne by all Limited Partners of the Feeder Fund on a pro-rata basis before giving effect to any repurchase of interests in the Master Fund effective as of that date, and will decrease the net profits or increase the net losses of the Master Fund that are credited to its interest holders, including each Feeder Fund.

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 Servicing Agent did not waive any of the servicing fees for the period ended September 30, 2009.

The Investment Manager contractually agreed to reimburse certain expenses through July 10, 2010, so that the total annual expenses (excluding taxes, interest, brokerage commissions, other transaction-related expenses, any extraordinary expenses of the Feeder Funds, any acquired fund fees and expenses, as well as any performance allocation payable by the Feeder Funds or the Master Fund) for this period will not exceed 2.35% for the Hatteras Multi-Strategy Fund, L.P. and Hatteras Multi-Strategy TEI Fund, L.P. and 1.75% for the Hatteras Multi-Strategy Institutional Fund, L.P. and

NOTES TO FINANCIAL STATEMENTS

September 30, 2009 (Unaudited) (continued)

4. RELATED PARTY TRANSACTIONS AND OTHER (CONTINUED)

Hatteras Multi-Strategy TEI Institutional L.P. (the “Expense Limitation”). The agreement automatically renews for one-year terms after the initial period until terminated by the Investment Manager or the applicable Feeder Fund. The Feeder Funds will carry forward, for a period not to exceed (3) three years from the date on which a reimbursement is made by the Investment Manager, any expenses in excess of the Expense Limitation and repay the Investment Manager such amounts, provided the Feeder Fund is able to effect such reimbursement and remain in compliance with the Expense Limitation disclosed in the then effective prospectus. There were no reimbursements from the Investment Manager, nor previous reimbursements repaid to the Investment Manager, for the period ending September 30, 2009.

The performance allocation is calculated at the Master Fund level, and allocated to the Feeder Funds based on each Feeder Fund ownership interest in the Master Fund. The General Partner is allocated a performance allocation (calculated and accrued monthly and payable annually) equal to 10% of the amount by which net new profits of the limited partner interests of the Master Fund exceed the non-cumulative “hurdle amount,” which is calculated as of the last day of the preceding calendar year of the Master Fund at a rate equal to the yield-to-maturity of the 90 day U.S. Treasury Bill as reported by the Wall Street Journal for the last business day of the preceding calendar year (the “Performance Allocation”). The Performance Allocation is made on a “peak to peak,” or “high watermark” basis, which means that the Performance Allocation is made only with respect to new net profits. If the Master Fund has a net loss in any period followed by a net profit, no Performance Allocation will be made with respect to such subsequent appreciation until such net loss has been recovered. For the period ended September 30, 2009 there was no performance based allocation.

UMB Bank, N.A. serves as custodian of the Feeder Funds’ cash balances and provides custodial services for the Feeder Funds. UMB Fund Services, Inc. serves as administrator and accounting agent to the Feeder Funds and provides certain accounting, record keeping and investor related services. The Feeder Funds pay a monthly fee to the custodian and administrator based upon average Limited Partners’ capital, subject to certain minimums.

5. RISK FACTORS

An investment in the Feeder Funds 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 Adviser Fund holdings for extended periods, which may be several years. No guarantee or representation is made that the investment objective will be met.

6. REPURCHASE OF PARTNERS’ UNITS

The Board may, from time to time and in its sole discretion, cause the Feeder Funds to repurchase Units from Limited Partners pursuant to written tenders by Limited Partners at such times and on such terms and conditions as established by the Board. In determining whether the Feeder Funds should offer to repurchase interests, the Board will consider, among other things, the recommendation of the Investment Manager. The Feeder Funds generally expect to offer to repurchase units from Limited Partners on a quarterly basis as of March 31, June 30, September 30 and December 31 of each year. The Feeder Funds do not intend to distribute to the Limited Partners any of the Feeder Funds’ income, but generally expect 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. Units repurchased prior to the Limited Partner’s one year anniversary of its initial investment is subject to a maximum 5% repurchase fee.

September 30, 2009 (Unaudited) (continued)

7. INDEMNIFICATION

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

8. FINANCIAL HIGHLIGHTS

The financial highlights are intended to help an investor understand the Feeder Funds’ financial performance. The total returns in the table represent the rate that a Limited Partner would be expected to have earned or lost on an investment in each Feeder Fund.

The ratios and total return amounts are calculated based on each Limited Partner group taken as a whole. The General Partner’s interest is excluded from the calculations. An individual Limited Partner’s ratios or returns may vary from the table below based on performance 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 Partners’ capital. The ratios include the Feeder Funds’ 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 portfolio turnover rate is calculated based on the Master Fund’s investment activity, as turnover occurs at the Master Fund level and the Feeder Funds are typically invested 100% in the Master Fund.

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 and commenced operations on January 1, 2005. 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 provide capital appreciation consistent with the return characteristic of the alternative investment portfolios of larger endowments through investments in the six asset classes of Opportunistic Equity, Enhanced Fixed Income, Absolute Return, Real Estate, Private Equity, and Energy and Natural Resources. The Master Fund’s secondary objective is to provide capital appreciation with less volatility than that of the equity markets. To achieve its objective, the Master Fund will provide its limited partners (each, a “Limited Partner” and together, the “Limited Partners”) with access to a broad range of investment strategies, asset categories, and trading Advisers (“Advisers”) and by providing overall asset allocation services typically available on a collective basis to larger institutions. The Master Fund invests with each Adviser either by becoming a participant in an investment vehicle operated by the Adviser (an “Adviser Fund”) which includes exchange traded funds (“ETFs”), hedge funds, investment funds or directly in exchange traded funds or by placing its assets in an account directly managed by the Adviser.

Hatteras Investment Management LLC, a Delaware limited liability company, serves as the General Partner of the Master Fund (the “General Partner”). The General Partner is an affiliate of the Investment Manager. The General Partner has appointed a Board of Directors (the “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.

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting and reporting policies used in preparing the financial statements.

a. Basis of Accounting

The Master Fund’s accounting and reporting policies conform with generally accepted accounting principles within the United States (“U.S. GAAP”).

b. Cash

Cash includes short-term interest-bearing deposit accounts. At times, such deposits may be in excess of federally insured limits. The Master Fund has not experienced any losses in such accounts and does not believe it is exposed to any significant credit risk on such accounts.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

c. Valuation of Investments

Investments held by the Master Fund include:

•	Investments in Adviser Funds—The Master Fund will value interests in the Adviser Funds 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 Adviser Funds are subject to the terms of the Adviser Funds’ offering documents. Valuations of the Adviser Funds may be subject to estimates and are net of management and performance incentive fees or allocations payable to the Adviser Funds’ as required by the Adviser Funds’ offering documents. If the Investment Manager determines that the most recent value reported by the Adviser Fund does not represent fair value or if the Adviser 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.
	The interests of some Adviser Funds, primarily investments in private equity funds, may be valued less frequently than the calculation of the Master Fund’s net asset value. Therefore, the reported performance of the Adviser Fund may lag the reporting period of the Master Fund. The Investment Manager has established procedures for reviewing the effect on the Master Fund’s net asset value due to this lag in reported performance of the Adviser Funds.
•	Investments in Exchange Traded Funds—Securities traded on one or more of the U.S. national securities exchanges or the OTC Bulletin Board will be valued at their last sales price. Securities traded on NASDAQ will be valued at the NASDAQ Official Closing Price (“NOCP”), at the close of trading on the exchanges or markets where such securities are traded for the business day as of which such value is being determined.

The Fund classifies its assets and liabilities into three levels based on the lowest level of input that is significant to the fair value measurement. Estimated values may differ from the values that would have been used if a ready market existed or of the investments were liquidated at the valuation date.

The three-tier hierarchy to distinguish between (1) inputs that reflect the assumptions market participants would use in pricing an asset or liability developed based on market data obtained from sources independent of the reporting entity (observable inputs) and (2) inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing an asset or liability developed based on the best information available in the circumstances (unobservable inputs) and to establish classification of fair value measurements for disclosure purposes. Various inputs are used in determining the value of the Master Fund’s investments. The inputs are summarized in the three broad levels listed below:

Valuation of Investments

• Level 1—quoted prices (unadjusted) in active markets for identical investments

• Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

• Level 3—significant unobservable inputs (including the Master Fund’s own assumptions in determining the fair value of investments)

The amount of the net change in unrealized appreciation/depreciation for the period ended September 30, 2009 relating to investments in Level 3 assets still held at September 30, 2009 is $155,566,389, which is included as a component of net change in unrealized appreciation on investments in Adviser Funds.

Authoritative accounting guidance requires disclosures about the reporting entity’s derivative instruments and hedging activities, by providing for qualitative disclosures about the objectives and strategies for using derivatives, quantitative data about the fair value of and gains and losses on derivative contracts, and details of credit-risk-related contingent features in their hedged positions. As of September 30, 2009, the Master Fund had not entered into any derivative instruments.

NOTES TO FINANCIAL STATEMENTS

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

d. Investment Income

Interest income is recorded when earned. Dividend income is recorded on the ex-dividend date, except that certain dividends from private equity investments are recorded as soon as the information is available to the Master Fund.

The Adviser Funds generally do not make regular cash distributions of income and gains and are therefore considered non-income producing securities. Disbursements received from Adviser Funds are accounted for as a reduction to cost.

e. Fund Expenses

The Master Fund will bear all expenses incurred, on an accrual basis, 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, auditing, and tax preparation fees; custodial fees; fees for data and software providers; costs of insurance; registration expenses; directors’ fees; interest expenses and commitment fees on credit facilities; and expenses of meetings of the Board.

f. Income Taxes

The Master Fund is treated as a partnership for federal income tax purposes and therefore is not subject to U.S. 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 profit and loss.

The Fund has reviewed any potential tax positions as of September 30, 2009 and has determined that it does not have a liability for any unrecognized tax benefits. The Master Fund recognizes interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the Statement of Operations. During the period, the Master Fund did not incur any material interest or penalties. For the years ended December 31, 2006 through December 31, 2008 the Master Fund is open to examination by U.S. federal tax authorities and state tax authorities.

g. Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires the Master Fund 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 increases and decreases in Partners’ Capital from operations during the reporting period. Actual results could differ from those estimates.

3. ALLOCATION OF PARTNERS’ CAPITAL

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 Limited 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 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.

NOTES TO FINANCIAL STATEMENTS

4. REPURCHASE OF PARTNERS’ INTERESTS

The Board may, from time to time and in its sole discretion, cause the Master Fund to repurchase interests from Limited Partners pursuant to written tenders by Limited 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, among other things, the recommendation of the Investment Manager. The Investment Manager generally recommends to the Board that the Master Fund offer to repurchase interests from Limited Partners, up to 5% of the net asset value of the Master Fund, on a quarterly basis as of the valuation date at the end of each calendar quarter. The Master Fund does not intend to distribute to the partners any of the Master Fund’s income, but generally expects to reinvest substantially all income and gains allocable to the partners.

5. MANAGEMENT FEES, PERFORMANCE ALLOCATION, AND RELATED PARTY TRANSACTIONS

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 Master 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 partners’ capital determined as of the last day of the month (before repurchase of interests).

The General Partner is allocated a performance allocation (calculated and accrued monthly and payable annually) equal to 10% of the amount by which net new profits of the limited partner interests of the Master Fund exceed the non-cumulative “hurdle amount,” which is calculated as off the last day of the preceding calendar year of the Master Funds at a rate equal to the yield-to-maturity of the 90-day U.S. Treasury Bill as reported by the Wall Street Journal for the last business day of the last calendar year (“the performance Allocation”). The performance Allocation is made on a “peak to peak,” or “high watermark” basis, which means that the Performance Allocation will be made with respect to such subsequent appreciation until such net loss has been recovered.

Hatteras Capital Distributors LLC, an affiliate of the Investment Manager, serves as the Master Fund’s private placement agent.

Each member of the Board who is not an “interested person” of the Master Fund (the “Independent Board”), as defined by the 1940 Act, receives an annual retainer of $30,000. All Board members are reimbursed by the Master Fund for all reasonable out-of-pocket expenses incurred by them in performing their duties.

6. ACCOUNTING, ADMINISTRATION, AND CUSTODIAL AGREEMENT

In consideration for accounting, administrative, and recordkeeping services, the Master Fund pays UMB Fund Services, Inc. (the “Administrator”) a monthly administration fee based on the month-end net asset value of the Master Fund. The Administrator also provides regulatory administrative services, transfer agency functions, and shareholder services at an additional cost. For the period ended September 30, 2009, the total administration fee was $469,962.

UMB Bank, N.A. serves as custodian of the Master Fund’s assets and provides custodial services for the Master Fund.

7. INVESTMENT TRANSACTIONS

Total purchases of Adviser Funds for the period ended September 30, 2009 amounted to $178,048,950. Total proceeds from redemptions of Adviser Funds for the period ended September 30, 2009 amounted to $64,495,711. The cost of investments in Adviser Funds for U.S. federal income tax purposes is adjusted for items of taxable income allocated to the Master Fund from the Adviser Funds. The Master Fund relies upon actual and estimated tax information provided by the Adviser Funds as to the amounts of taxable income allocated to the Master Fund as of September 30, 2009.

The Master Fund invests 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.

8. LINE OF CREDIT

The Master Fund maintains a $40,000,000 unsecured, uncommitted revolving credit facility (“Facility”), for the purpose of financing short timing differences between the redemption of investments or receipt of partnership capital and the withdrawal of partnership capital accounts, investing in Adviser Funds, or as general working capital. The Facility can be terminated on demand by the lender. A fee of 65 basis points per annum is payable quarterly in arrears on the unused portion of the Facility. The interest rate charged on borrowings is, at the Borrower’s option, (a) the London Interbank Offer Rate plus a spread of 375 basis points, or (b) a Base Rate, as determined by the Lender, plus 200 basis points. Interest and fees incurred for the period ended September 30, 2009 are disclosed in the accompanying Statement of Operations. At September 30, 2009, the Master Fund had no borrowings, fees or interest payable outstanding under the Facility. The average interest rate, the average daily balance, and the maximum balance outstanding for borrowings under the Facility for the period ended September 30, 2009 was 5.25%, $819,672, and $15,000,000, respectively.

9. INDEMNIFICATION

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, 2009, the Master Fund had outstanding investment commitments to Adviser Funds totaling approximately $348,900,124.

11. RISK FACTORS

An investment in the Master Fund involves significant risks, including leverage risk, liquidity risk, interest rate risk and economic conditions risk, 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. Investments in the Adviser Funds may be restricted from early redemptions or subject to fees for early redemptions as part of contractual obligations agreed to by the Investment Manager on behalf of the Master Fund. Adviser Funds may have initial lock-up periods, the ability to suspend redemptions, or employ the use of side pockets, all of which may affect the Master Fund’s liquidity in the Adviser Fund.

Adviser Funds generally require the Investment Manager to provide advanced notice of its intent to redeem the Master Fund’s total or partial interest and may delay or deny a redemption request depending on the Adviser Funds’ governing agreements. Interests in the Master Fund provide limited liquidity since Limited Partners will not be able to redeem interests on a daily basis because the Master Fund is a closed-end fund. Therefore investment in the Master Fund is suitable only for investors who can bear the risks associated with the limited liquidity of interests and should be viewed as a long-term investment. No guarantee or representation is made that the investment objective will be met.

12. FINANCIAL HIGHLIGHTS

The financial highlights are intended to help an investor understand the Master Fund’s financial performance for the past period. The total returns in the table represent the rate that a typical Limited Partner would be expected to 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. 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 net investment income or expenses, as applicable, by the average of total monthly Limited Partners’ capital. The ratios do not reflect the Master Fund’s proportionate share of income and expenses from Adviser Funds. The ratios are annualized for periods of less than a year.
