1. Organization

Excelsior Directional Hedge Fund of Funds Master Fund, LLC, formerly known as
Excelsior Directional Hedge Fund of Funds, LLC (the "Company"), was organized as
a limited liability company under the laws of Delaware on July 6, 2000, and
commenced operations on October 1, 2000. The Company is registered under the
Investment Company Act of 1940, as amended (the "1940 Act"), as a closed-end,
non-diversified, management investment company. The Company's investment
objective is to seek capital appreciation. The Company pursues its investment
objective principally through a multi-manager, multi-strategy program of
investments in a diverse group of investment funds that primarily invest or
trade in a wide range of equity and debt securities. The investment managers
selected by the Company generally conduct their investment programs through
these investment funds (collectively, the "Investment Funds") in which the
Company invests as a limited partner or member along with other investors.

On April 23, 2007, pursuant to member approval, the Company was reorganized into
a "master/feeder" investment structure (the "Reorganization"). Effective that
date, the Company became a master fund and member interests in the Company were
transferred to a new entity, Excelsior Directional Hedge Fund of Funds (TI),
LLC, a Delaware limited liability company that is registered under the 1940 Act
as a closed-end, non-diversified, management investment company (the "Feeder
Fund"). The Feeder Fund in turn invested substantially all of its assets into
the Company. On July 1, 2007, Excelsior Directional Hedge Fund of Funds, Ltd.
(the "Offshore Fund") also became a feeder of the Company.

The Feeder Fund and the Offshore Fund (together, the "Feeder Funds") pursue
their investment objectives by investing substantially all of their interests in
the Company. The Feeder Funds have the same investment objective and
substantially the same investment policies as the Company (except that the
Feeder Funds pursue their investment objectives by investing in the Company).

U.S. Trust Hedge Fund Management, Inc. serves as the investment adviser of the
Company (the "Adviser"). The Adviser is an indirect wholly-owned subsidiary of
Bank of America Corporation ("Bank of America"). Bank of America is a bank
holding and a financial holding company which has its principal executive
offices at 101 North Tryon Street, Charlotte, North Carolina. The Adviser is
responsible for developing, implementing and supervising the investment program
and providing day-to-day management services.

The Board of Managers (the "Board") has overall responsibility to manage and
supervise the operations of the Company, including the exclusive authority to
oversee and to establish policies regarding the management, conduct and
operation of the Company's business. The Board has engaged the Adviser to
provide investment advice regarding the selection of Investment Funds and to
manage the day-to-day operations of the Company.

1. Organization (continued)

The Company was established to hold substantially all of the assets of the
Feeder Fund and the Offshore Fund, as members of the Company ("Members"). As of
September 30, 2008, the Feeder Fund's and Offshore Fund's ownership of the
Company's Members' Equity--Net Assets were 68.75% and 31.25%, respectively.

Member subscriptions for interests in the Company ("Interests") by eligible
investors may be accepted as of the first day of each calendar quarter, or at
such times as the Board may determine. The Company may, from time to time, offer
to repurchase Interests from its Members pursuant to written tenders by Members.
These repurchase offers will be made at such times and on such terms as may be
determined by the Board, in its sole discretion, subject to the liquidity of the
Company's assets and other factors considered by the Board. The Adviser expects
that, generally, it will recommend to the Board that the Company offer to
repurchase Interests from Members twice in each year, at June 30th and December
31st. Members can only transfer or assign Company Interests under certain
limited circumstances.

2. Significant Accounting Policies

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Management believes that the estimates utilized in preparing
the Company's financial statements are reasonable and prudent; however, actual
results could differ from these estimates.

a. Portfolio Valuation

The net asset value of the Company is determined by, or at the direction of, the
Adviser as of the close of business at the end of each fiscal period (as defined
in the Company's Limited Liability Company Agreement), in accordance with the
valuation principles set forth below, or as may be determined from time to time
pursuant to policies established by the Board.

Ordinarily, the Company's investments in Investment Funds are carried at fair
value as determined by the Company's pro-rata interest in the net assets of each
Investment Fund as reported by the investment manager, who determines the value
of the Investment Fund's net assets. The values of the Investment Funds' net
assets are determined in accordance with their valuation policies as described
in their respective offering memoranda or operating agreements. All valuations
utilize financial information supplied by the investment manager of each
Investment Fund and are net of management and performance incentive fees or
allocations pursuant to the Investment Funds' agreements. The investments in
Investment Funds, representing 99.83% of the Members' equity, have been fair
valued in accordance with procedures established by the Board.

                                                              September 30, 2008

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

2. Significant Accounting Policies (continued)

a. Portfolio Valuation (continued)

As a general matter, the fair value of the Company's interests in an Investment
Fund will represent the amount that the Company could reasonably expect to
receive from the Investment Fund if the Company's interests were redeemed at the
time of valuation, based on information reasonably available at the time the
valuation is made and that the Adviser believes to be reliable. The Adviser, or,
in certain cases, the Board, will consider such information, and may conclude in
certain circumstances that the information provided by an Investment Fund's
manager does not represent the fair value of the Company's interests in an
Investment Fund. Following procedures adopted by the Board, and in the absence
of specific transaction activity in interests in a particular Investment Fund,
the Company could consider whether it was appropriate, in light of all relevant
circumstances, to value such a position at the Investment Fund's net asset value
as reported at the time of valuation, or whether to adjust such value to reflect
a premium or discount to net asset value. Any such decision must be made in good
faith, and subject to the review and supervision of the Board. Because of the
inherent uncertainty of valuation, the values of the Company's investments may
differ significantly from the values that would have been used had a ready
market for the investments held by the Company been available. The Company's
investment in Durus Life Sciences Fund, LLC ("Durus") is valued at $53,623 and
represents 0.01% of the Company's Members' Equity - Net Assets as of September
30, 2008. Durus was fair valued in good faith by the Adviser, in accordance with
procedures adopted by the Board. As of September 30, 2008, Durus is in
liquidation and there are no ongoing redemption rights available to partners.

In September 2006, the Financial Accounting Standards Board ("FASB") released
Statement of Financial Accounting Standards ("SFAS") No. 157, which provides
enhanced guidance for using fair value to measure assets and liabilities. The
Company adopted SFAS No. 157 on April 1, 2008. SFAS No. 157 establishes a fair
value hierarchy and specifies that a valuation technique used to measure fair
value shall maximize the use of observable inputs and minimize the use of
unobservable inputs. The objective of a fair value measurement is to determine
the price that would be received to sell an asset or paid to transfer a
liability in an orderly transaction between market participants at the
measurement date (an exit price). Accordingly, the fair value hierarchy gives
the highest priority to quoted prices (unadjusted) in active markets for
identical assets or liabilities (Level 1) and the lowest priority to
unobservable inputs (Level 3). The three levels of the fair value hierarchy
under SFAS No. 157 are described below:

                                                              September 30, 2008

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

2. Significant Accounting Policies (continued)

a. Portfolio Valuation (continued)

Level 1 -  Unadjusted quoted prices in active markets for identical,
           unrestricted assets or liabilities that the Company has the ability
           to access at the measurement date;

Level 2 -  Quoted prices which are not active, or inputs that are observable
           (either directly or indirectly) for substantially the full term of
           the asset or liability; and

Level 3 -  Prices, inputs or exotic modeling techniques which are both
           significant to the fair value measurement and unobservable (supported
           by little or no market activity).

As required by SFAS No. 157, investments are classified within the level of the
lowest significant input considered in determining fair value. Investments
classified within Level 3 consider several inputs and may include Level 1 or
Level 2 inputs as components of the overall fair value measurement. The table
below sets forth information about the level within the fair value hierarchy at
which the Company's investments are measured at September 30, 2008:

                  Level 1   Level 2     Level 3       Total
                  ----------------------------------------------

Investment Funds  $   -     $   -   $ 361,999,418  $ 361,999,418

                  ==============================================

Distributions received from Investment Funds, whether in the form of cash or
securities, are applied first as a reduction of the investment's cost, and any
excess is treated as realized gain from investments in Investment Funds.
Realized gains or losses on investments in Investment Funds are measured by the
difference between the proceeds from the sale or liquidation and the cost basis
of the investment using the specific identification method without regard to
unrealized appreciation or depreciation reported in prior years.

b. Company Expenses

The Company bears certain expenses incurred in its business, including, but not
limited to, the following: fees paid directly or indirectly to the investment
managers of the Investment Funds; all costs and expenses directly related to
portfolio transactions and positions for the Company's account; legal fees;
accounting and auditing fees; custodial fees; fees paid to the Company's
administrator; costs of insurance; advisory fees; travel and related expenses of
the Board; all costs with respect to communications regarding the Company's
transactions among the Adviser and any custodian or other agent engaged by the
Company; and other types of expenses approved by the Board.

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

c. Income Taxes

As a limited liability company, no provision for the payment of Federal, state
or local income taxes has been provided by the Company. Each Member is
individually required to report on its own tax return its share of the Company's
taxable income or loss. The Company has a tax year end of December 31.

Net investment income or loss and net realized and unrealized gain or loss from
investments of the Company for each fiscal period are allocated among, and
credited to or debited against, the capital accounts of all Members as of the
last day of the fiscal period in accordance with each Member's respective
investment percentage for the fiscal period, as defined in the Company's Limited
Liability Company Agreement.

The cost of the Company's investments in Investment Funds for Federal income tax
purposes is based on amounts reported to the Company by the Investment Funds on
a Schedule K-1 or PFIC annual information statement for the year ended December
31, 2007. Based on Investment Funds owned at December 31, 2007, the cost of
investments for Federal income tax purposes was $303,932,199. This included
aggregate gross unrealized appreciation of $35,480,886 and aggregate gross
unrealized depreciation of $2,332,690.

Effective April 1, 2007, the Company adopted FASB Interpretation No. 48,
"Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides
guidance for how uncertain tax positions should be recognized, measured,
presented and disclosed in the financial statements. FIN 48 requires the
evaluation of tax positions taken or expected to be taken in the course of
preparing the Company's tax returns in order to determine whether the tax
positions are "more-likely-than-not" of being sustained by the applicable tax
authority. Tax positions not deemed to meet the "more-likely-than-not" threshold
would be recorded as a tax benefit or expense in the current year. The Company
has evaluated the application of FIN 48 and has determined that it does not have
a material impact on the Company's financial statements. There is no tax
liability resulting from unrecognized tax benefits relating to uncertain income
tax positions taken or expected to be taken on the tax return for the year ended
December 31, 2007. No income tax returns are currently under examination. The
statute of limitations on the Company's U.S. Federal tax returns remains open
for the years ended December 31, 2005 through December 31, 2007. The statute of
limitations on the Company's state and local tax returns may remain open for an
additional year depending upon the jurisdiction.

d. Other

Cash and cash equivalents consist of amounts maintained in a PFPC Trust Company
interest-bearing account. Interest income is recorded on the accrual basis.

3. Advisory Fee, Related Party Transactions and Other

The Adviser provides certain investment advisory services and incurs research,
travel and other expenses related to the selection and monitoring of investment
managers. Further, the Adviser provides certain management and administrative
services to the Company, including providing office space and other support
services, maintaining files and records, and preparing and filing various
regulatory materials. In consideration for such services, the Company pays the
Adviser a quarterly advisory fee at an annual rate of 1.0% based on the
Company's net assets on the first business day of each quarter after adjustment
for any subscriptions effective on that date. Each Feeder Fund also pays the
Adviser a quarterly management fee at an annual rate of 0.5% based on the Feeder
Fund's net assets on the first business day of each quarter after adjustment for
any subscriptions effective on that date. Prior to the Reorganization, the
Company paid the Adviser an advisory fee at an annual rate of 1.5% based on the
Company's net assets on the first business day of each quarter after adjustment
for any subscriptions effective on that date. The change in the fee structure
resulting from the Reorganization does not have a material impact on the total
advisory and management fees attributable to the capital accounts of the
investors of the Feeder Funds.

For the period from April 1, 2008 to September 30, 2008, the Company incurred
advisory fees totaling $1,926,610, based on the current advisory fee rate of
1.0%. Of total advisory fees, $995,186 was payable as of September 30, 2008.

As of September 26, 2008, the Board is made up of three Managers who are not
"interested persons," as defined by Section 2(a)(19) of the 1940 Act, of the
Company (the "Disinterested Managers"). David R. Bailin, a member of the Board
who was an "interested person" of the Company, as defined under the 1940 Act,
resigned from the Board effective September 26, 2008. The Disinterested Managers
receive an annual retainer of $10,000 and per-meeting fees of: $2,000 for
in-person attendance at quarterly meetings of the Board; $1,000 for telephone
participation at a quarterly Board meeting or for participation at a telephonic
special meeting of the Board; and $1,000 for each audit committee meeting
(whether held in-person or by telephone). All Disinterested Managers may be
reimbursed for expenses of attendance, if any, at each regular or special
meeting of the Board or of any committee thereof and for their expenses, if any,
in connection with any other service or activity they perform or engage in as
Managers. Any managers who are "interested persons," as defined in the 1940 Act,
of the Company, if any, do not receive any retainer or other fee from the
Company. The Company incurred $27,500 of retainer and per meeting fees for the
period from April 1, 2008 to September 30, 2008, none of which is payable as of
September 30, 2008.

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

 3. Advisory Fee, Related Party Transactions and Other (Continued)

The Company has retained J.D. Clark & Company (the "Administrator") to provide
accounting and certain administrative and investor services to the Company. As a
result of the Reorganization, the Company's contract with the Administrator was
amended to reflect the new "master/feeder" structure. Previously, the Company
paid the Administrator a quarterly fee equal to the greater of: (i) $3,000; or
(ii) .00025 of the Company's net assets as of the first day of each calendar
quarter on the first $150 million of net assets, plus .000125 of the Company's
net assets in excess of $150 million. As of April 23, 2007, the Company pays the
Administrator a quarterly fee equal to $3,000 per Feeder Fund invested in the
Company. For the period from April 1, 2008 to September 30, 2008, the Company
incurred $12,000 in expenses related to such administrative services, $6,000 of
which was payable as of September 30, 2008. The Feeder Funds incur additional
expenses directly for the services provided by the Administrator.

4. Financial Instruments with Off-Balance Sheet Risk

In the normal course of business, the Investment Funds in which the Company
invests trade various financial instruments and enter into various investment
activities with off-balance sheet risk. These may include, but are not limited
to, short selling activities, writing option contracts, contracts for
differences and equity swaps. However, as a result of the investments by the
Company as a limited partner or member, the Company's liability with respect to
its investments in the Investment Funds is limited to the net asset value of its
interest in each Investment Fund.

5. Investments in Investment Funds

As of September 30, 2008, the Company had investments in thirty-one Investment
Funds. The Company, as an investor in these Investment Funds, is charged
management fees ranging from 0.0% to 2.0% (per annum) of the net asset value of
its ownership interests in the Investment Funds, as well as incentive fees or
allocations ranging from 15% to 20% of net profits earned that are attributable
to the Company's ownership interests in such Investment Funds. The Company also
generally bears a pro rata share of the other expenses of each Investment Fund
in which it invests. Total expenses, including incentive fees or allocations,
for the fiscal year ended March 31, 2008, ranged from approximately 1.5% to
14.7% of the Company's average invested capital in each Investment Fund.
Incentive fees or allocations for the same fiscal year ranged from approximately
0.0% to 8.1% of the Company's average invested capital in each Investment Fund.
These ratios may vary over time depending on the allocation of the Company's
assets among the Investment Funds and the actual expenses and investment
performance of the Investment Funds. Although the ranges of Investment Fund
expense ratios are based on audited financial data received from the Investment
Funds, the ranges were not reviewed by the Company's auditors.

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

5. Investments in Investment Funds (continued)

In general, most of the Investment Funds in which the Fund invests provide for
periodic withdrawals of capital ranging from monthly to annually and, in some
cases, have lock up provisions under which the Fund may not withdraw capital for
a specified period after the date of its contribution, which may be up to three
years. The governing documents of Investment Funds generally provide that the
Investment Fund may suspend, limit or delay the right of its investors, such as
the Fund, to withdraw capital. In addition, some of the Investment Funds may
invest a portion of their assets in illiquid securities and may not permit the
portion of the Fund's capital invested in these Investment Funds that is
allocable to illiquid securities to be withdrawn until the securities are sold
or become liquid.

Aggregate purchases and proceeds of interests in Investment Funds for the period
from April 1, 2008 to September 30, 2008 are $96,000,000 and $26,486,386,
respectively.

6. Bank Note-Line of Credit Facility

The Company maintains a $30,000,000 revolving line of credit agreement with a
U.S. financial institution that is collateralized by the Company's cash and
investments. Based upon the election of the Company, interest accrues at either
the financial institution's prime rate less 1.25% per annum or Libor plus 1.5%
per annum. The note also includes a provision for a facility fee of 0.375% per
annum on the unused portion of the note. For the period from April 1, 2008 to
September 30, 2008, the Company incurred $57,188 in facility fees related to the
bank line of credit, $28,750 of which was payable as of September 30, 2008. As
of September 30, 2008, the Company did not have an outstanding revolving note
balance.

7. Guarantees

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

8. Subsequent Events

As of September 30, 2008, the Company received subscriptions in advance for
Interests from Members in the amount of $36,699,000, which is reflected as
Members' interests received in advance on the Statement of Assets, Liabilities
and Members' Equity - Net Assets. These subscriptions became Interests in the
Company effective October 1, 2008.
