ITEM 1.   SUMMARY TERM SHEET.

          As stated in the offering  documents of Excelsior Absolute Return Fund
of Funds  Master  Fund,  LLC (the  "Fund"),  the Fund is offering to  repurchase
limited  liability  company  interests in the Fund ("Interest" or "Interests" as
the context  requires)  from members of the Fund  ("Members") at their net asset
value (that is, the value of the Fund's assets minus its liabilities, multiplied
by the proportionate interest in the Fund a Member desires to tender). The offer
to repurchase  Interests  (the  "Offer") will remain open until 12:00  midnight,
Eastern Time, on Thursday,  November 10, 2005, unless the Offer is extended. The
net asset value of the Interests will be calculated for this purpose on December
30, 2005 or, if the Offer is extended,  on the last business day of the month in
which the Offer expires (the "Valuation  Date").  The Fund reserves the right to
adjust the  Valuation  Date to correspond  with any extension of the Offer.  The
Fund will review the net asset value calculation of Interests as of December 30,
2005,  during the Fund's audit for its fiscal year ending March 31, 2006,  which
the Fund expects will be  completed  by the end of



May 2006.  This  December 30, 2005 net asset value,  as reviewed,  will  be used
to determine  the final amount paid for tendered Interests.

          Members may tender their entire Interest,  a portion of their Interest
defined as a specific  dollar value or the portion of their  Interest  above the
required  minimum  capital  account  balance.  If a Member  tenders  its  entire
Interest (or a portion of its  Interest)  and the Fund accepts that Interest for
repurchase,   the  Fund   will   give  the   Member  a   non-interest   bearing,
non-transferable promissory note (the "Note") entitling the Member to receive an
amount  equal  to the net  asset  value  of the  Interest  tendered  (valued  in
accordance with the Fund's Limited  Liability  Company Agreement dated September
2, 2003 (the "LLC  Agreement"))  determined  as of December  30, 2005 (or if the
Offer is extended,  the net asset value  determined on the Valuation  Date). The
Note will be held in a special custody account with PFPC Trust Company ("PFPC").

          If a Member  tenders its entire  Interest,  the Note will  entitle the
Member to receive  an  initial  payment  in cash  and/or  marketable  securities
(valued  in  accordance  with the LLC  Agreement)  equal to at least  95% of the
unaudited  net  asset  value of the  Interest  tendered  by the  Member  that is
accepted for repurchase by the Fund (the "Initial  Payment") and will be paid to
the  Member's  account  with U.S.  Trust  Company,  N.A.  or an  affiliate  bank
(collectively,  "U.S.  Trust"),  or mailed to the Member if the Member  does not
have a U.S. Trust account,  within 30 calendar days after the Valuation Date or,
if the Fund has requested  withdrawals of its capital from any investment  funds
in order to finance the repurchase of Interests,  within ten business days after
the Fund has received at least 95% of the aggregate amount withdrawn by the Fund
from such investment funds.

          The Note will also entitle the Member to receive a contingent  payment
(the  "Contingent  Payment")  equal to the excess,  if any, of (a) the net asset
value of the  Interest  tendered  by the  Member  and  accepted  by the Fund for
repurchase,  determined as of the Valuation Date, as it may be adjusted based on
the next annual audit of the Fund's March 31, 2006  financial  statements,  over
(b) the  Initial  Payment.  The Fund will  deposit the  aggregate  amount of the
Contingent  Payments in a separate,  interest  bearing  account and will pay any
interest  actually  earned thereon PRO RATA to the Members whose  Interests have
been repurchased. The Contingent Payment (plus any interest earned) will be paid
within ten calendar days after the  completion  of the Fund's annual audit.  The
Contingent Payment will also be deposited into the tendering Member's account at
U.S.  Trust,  or mailed to the Member if the Member  does not have a U.S.  Trust
account.

          A Member that tenders for  repurchase  only a portion of such Member's
Interest  will  receive a Note that will entitle the Member to a payment in cash
and/or marketable securities (valued in accordance with the LLC Agreement) equal
to 100% of the net asset  value of the portion of the  Interest  tendered by the
Member that is accepted for repurchase by the Fund. Payment pursuant to the Note
will be made to the Member's  account at U.S. Trust or mail to the Member if the
Member does not have a U.S.  Trust  account,  within 30 calendar  days after the
Valuation Date or, if the Fund has requested withdrawals of its capital from any
investment  funds in order to finance the  repurchase of  Interests,  within ten
business days after the Fund has received at least 95% of the  aggregate  amount
withdrawn by the Fund from such investment funds.

          A Member that tenders for  repurchase  only a portion of such Member's
Interest  must  tender a minimum of $25,000  and will be  required to maintain a
capital account balance equal to $100,000 or more.

                                      -2-


          The  Fund  reserves  the  right to  repurchase  less  than the  amount
tendered by a Member if the repurchase  would cause the Member's capital account
in the Fund to have a value  less than the  required  minimum  balance or if the
total amount  tendered by Members is more than $30 million.  If the Fund accepts
the  tender  of the  Member's  entire  Interest  or a portion  of such  Member's
Interest for repurchase, the Fund will make payment for Interests it repurchases
from one or more of the following sources: cash on hand;  withdrawals of capital
from investment funds in which the Fund has invested;  proceeds from the sale of
securities and portfolio assets held by the Fund;  and/or  borrowings (which the
Fund does not currently intend to do).

          Following  this  summary  is a formal  notice of the  Fund's  offer to
repurchase  the  Interests.  The  Offer  remains  open to  Members  until  12:00
midnight,  Eastern Time,  Thursday,  November 10, 2005, the expected  expiration
date of the Offer. Until that time, Members have the right to change their minds
and withdraw the tenders of their Interests. Members will also have the right to
withdraw tenders of their Interests at any time after Monday, December 12, 2005,
40 business days from the commencement of the Offer, assuming their Interest has
not been accepted for repurchase by the Fund on or before that date.

          If a Member  would  like  the Fund to  repurchase  its  Interest  or a
portion  of its  Interest,  it should  complete,  sign and  either (i) mail (via
certified  mail  return  receipt  requested)  or  otherwise  deliver a Letter of
Transmittal,  attached to this  document as Exhibit C, to U.S.  Trust Hedge Fund
Management,  Inc., the investment adviser of the Fund (the "Adviser"),  225 High
Ridge Road,  Stamford,  CT 06905,  attention  Peggy Lynn, or (ii) fax it to U.S.
Trust  Hedge Fund  Management,  Inc. at (203)  352-4456,  so that it is received
before 12:00  midnight,  Eastern  Time,  on Thursday,  November 10, 2005. If the
Member  chooses to fax the Letter of  Transmittal,  it should mail the  original
Letter of  Transmittal to the Adviser  promptly after it is faxed  (although the
original does not have to be received  before 12:00  midnight,  Eastern Time, on
Thursday,  November 10,  2005).  Of course,  the value of Interests  will change
between  September  30, 2005 (the last time prior to the date of the Offer as of
which net asset value has been calculated) and December 30, 2005, the date as of
which the value of Interests will be determined for purposes of calculating  the
repurchase price for Interests. Members may obtain the estimated net asset value
of their Interests,  which the Fund calculates  monthly based on the information
the Fund receives from the managers of the investment funds in which it invests,
by  contacting  the Adviser at (203)  352-4497 or at the address  listed  above,
Monday through  Friday,  except  holidays,  during normal business hours of 9:00
a.m. to 5:00 p.m. (Eastern Time).

          Please  note,  that just as each Member has the right to withdraw  the
tender of an Interest,  the Fund has the right to cancel, amend or postpone this
Offer at any time before 12:00 midnight, Eastern Time, on Thursday, November 10,
2005.  Also  realize  that  although  the Offer  expires on November 10, 2005, a
Member that tenders all or a portion of its  Interest  will remain a Member with
respect to the Interest tendered and accepted for repurchase by the Fund through
December 30, 2005, when the net asset value of the Member's Interest tendered to
the Fund for repurchase is calculated.

ITEM 4.  TERMS OF THIS TENDER OFFER.

          (a) (1) (i) Subject to the conditions set forth in the Offer, the Fund
will  repurchase up to $30 million of Interests that are tendered by Members and
not withdrawn as described in ITEM 1. The initial  expiration  date of the Offer
is 12:00 midnight, Eastern Time, on Thursday,  November 10, 2005, (such time and
date, the "Initial Expiration Date"), subject to any extension of the Offer. The
later of the  Initial  Expiration  Date or the latest time and date to which the
Offer is extended is called the "Expiration Date."

               (ii) The repurchase  price of Interests  tendered to the Fund for
repurchase  will be their net asset value,  determined as of the Valuation  Date
or, if the Offer is extended, on the last business day of the month in which the
Offer expires.

          Members may tender their entire Interest,  a portion of their Interest
defined as a specific  dollar value or the portion of their  Interest  above the
required  minimum capital account  balance.  Each Member that tenders its entire
Interest or a portion  thereof that is accepted for  repurchase  will be given a
Note within ten calendar  days of the  acceptance  of the Member's  Interest for
repurchase.  The Note will be held for the Members in a special  custody account
with PFPC.  The Note will  entitle the Member to be paid an amount  equal to the
value,  determined as of the Valuation  Date, of the Interest or portion thereof
being  repurchased  (subject to  adjustment  upon  completion of the next annual
audit of the Fund's financial statements).  This

                                      -4-


amount will be the value of the Member's capital account (or the portion thereof
being  repurchased) determined as of the Valuation Date and will be based on the
net asset value of the Fund's assets determined as of  that date,  after  giving
effect to all allocations to be made as of that date.

          If a Member  tenders its entire  Interest,  the Note will  entitle the
Member to receive an Initial Payment. Payment of this amount will be made within
30  calendar  days  after  the  Valuation  Date or,  if the  Fund has  requested
withdrawals  of its capital  from any  investment  funds in order to finance the
repurchase of Interests, within ten business days after the Fund has received at
least 95% of the  aggregate  amount  withdrawn by the Fund from such  investment
funds. The Note will also entitle a Member to receive a Contingent Payment equal
to the excess,  if any, of (a) the net asset value of the  Interest  tendered by
the Member and accepted by the Fund for repurchase as of the Valuation  Date, as
it may be  adjusted  based on the  annual  audit of the  Fund's  March 31,  2006
financial  statements,  over (b) the Initial Payment.  The Fund will deposit the
aggregate  amount of the  Contingent  Payments in a separate,  interest  bearing
account  and will  pay any  interest  actually  earned  thereon  PRO RATA to the
Members whose Interests have been repurchased.  The Contingent Payment (plus any
interest  earned) will be payable  within ten calendar days after the completion
of the Fund's next annual audit. It is anticipated  that the annual audit of the
Fund's  financial  statements  will be completed  within 60 days after March 31,
2006, the fiscal year end of the Fund.

          A Member that tenders for  repurchase  only a portion of such Member's
Interest  will  receive a Note that will entitle the Member to a payment in cash
and/or marketable securities (valued in accordance with the LLC Agreement) equal
to 100% of the net asset  value of the portion of the  Interest  tendered by the
Member that is accepted for repurchase by the Fund. Payment pursuant to the Note
will be made within 30 calendar  days after the  Valuation  Date or, if the Fund
has requested  withdrawals of its capital from any investment  funds in order to
finance the repurchase of Interests, within ten business days after the Fund has
received at least 95% of the  aggregate  amount  withdrawn by the Fund from such
investment funds.

          Although  the Fund has  retained the option to pay all or a portion of
the repurchase price for Interests by distributing  marketable  securities,  the
repurchase price will be paid entirely in cash except in the unlikely event that
the  Board  of  Managers  determines  that the  distribution  of  securities  is
necessary to avoid or mitigate any adverse  effect of the Offer on the remaining
Members.  In such event, the Fund would make such payment on a pro rata basis so
that each Member would receive the same type of consideration.

          A Member that  tenders  only a portion of such  Member's  Interest for
repurchase  must  tender a minimum of $25,000 and will be required to maintain a
capital account balance equal to $100,000 or more.

          A  copy  of:  (a)  the  Cover  Letter  to  the  Offer  and  Letter  of
Transmittal;  (b) the Offer; (c) a form of Letter of Transmittal;  (d) a form of
Notice of  Withdrawal  of Tender;  and (e) forms of Letters to Members  from the
Fund that will be sent in  connection  with the Fund's  acceptance of tenders of
Interest  for  repurchase  are  attached  hereto as  Exhibits  A, B, C, D and E,
respectively.

               (iii)  The  scheduled  expiration  date  of the  Offer  is  12:00
midnight, Eastern Time, Thursday, November 10, 2005.

                                      -5-



               (iv) Not applicable.

               (v) The Fund  reserves  the  right,  at any time and from time to
time,  to extend  the  period of time  during  which  the  Offer is  pending  by
notifying  Members of such  extension.  If the Fund  elects to extend the tender
period,  for the  purpose  of  determining  the  repurchase  price for  tendered
Interests, the estimated net asset value of such Interests will be determined at
the close of business on the last  business  day of the month after the month in
which the Offer  actually  expires.  During any such  extension,  all  Interests
previously tendered and not withdrawn will remain subject to the Offer. The Fund
also reserves the right,  at any time and from time to time, up to and including
the Expiration Date, to: (a) cancel the Offer in the  circumstances set forth in
Section 7 of the Offer and in the event of such cancellation,  not to repurchase
or pay for any Interests tendered pursuant to the Offer; (b) amend the Offer; or
(c) postpone the acceptance of Interests for repurchase.  If the Fund determines
to amend the Offer or to postpone the acceptance of Interests tendered, it will,
to the extent  necessary,  extend the period of time  during  which the Offer is
open as provided above and will promptly notify Members.

               (vi) A tender of an Interest  may be withdrawn at any time before
12:00 midnight,  Eastern Time, Thursday,  November 10, 2005 and, if the Fund has
not accepted such Interest for  repurchase,  at any time after Monday,  December
12, 2005, 40 business days from the commencement of the Offer.

               (vii) Members wishing to tender an Interest pursuant to the Offer
should  mail or fax a  completed  and  executed  Letter  of  Transmittal  to the
Adviser,  to the  attention of Peggy Lynn, at the address set forth on page 2 of
the Offer, or fax a completed and executed Letter of Transmittal to the Adviser,
also to the  attention  of Peggy Lynn,  at the fax number set forth on page 2 of
the Offer.  The completed and executed Letter of Transmittal must be received by
the Adviser,  either by mail or by fax, no later than the  Expiration  Date. The
Fund  recommends  that all  documents  be  submitted to the Adviser by certified
mail, return receipt requested, or by facsimile transmission.  A Member choosing
to fax a Letter of  Transmittal  to the  Adviser  must also send or deliver  the
original  completed and executed  Letter of Transmittal to the Adviser  promptly
thereafter.

          Any Member  tendering  an Interest  pursuant to the Offer may withdraw
its tender as  described  above in ITEM 4(vi).  To be  effective,  any notice of
withdrawal  must be timely  received by the Adviser at the address or fax number
set forth on page 2 of the Offer.  A form to use to give notice of withdrawal of
a tender is available by calling the Adviser at the telephone  number  indicated
on page 2 of the Offer.  A tender of an Interest  properly  withdrawn  shall not
thereafter  be  deemed  to be  tendered  for  purposes  of the  Offer.  However,
subsequent  to the  withdrawal  of a  tendered  Interest,  the  Interest  may be
tendered  again  prior  to the  Expiration  Date  by  following  the  procedures
described above.

               (viii) For purposes of the Offer, the Fund will be deemed to have
accepted  (and thereby  repurchased)  Interests  that are tendered when it gives
written  notice to the  tendering  Member of its  election  to  repurchase  such
Member's Interest.

               (ix) If more than $30 million of Interests  are duly  tendered to
the Fund prior to the Expiration  Date and not  withdrawn,  the Fund will in its
sole discretion either: (a) accept additional  Interests in accordance with Rule
13e-4(f)(1)(ii)  under the  Securities  Exchange  Act of 1934,  as amended;  (b)
extend the Offer,  if necessary,  and increase the amount of Interests

                                      -6-


that the Fund is offering  to repurchase  to  an  amount it  believes sufficient
to accommodate the excess Interests tendered as well as any  Interests  tendered
during the extended  Offer;  or (c) accept  Interests  tendered on or before the
Expiration Date for payment on a PRO RATA basis based on the aggregate net asset
value of tendered Interests.  The Offer may be extended,  amended or canceled in
various other circumstances described in (v) above.

               (x) The  repurchase of Interests  pursuant to the Offer will have
the effect of increasing the proportionate  interest in the Fund of Members that
do not tender  Interests.  Members that retain their Interests may be subject to
increased  risks  that may  possibly  result  from the  reduction  in the Fund's
aggregate assets resulting from payment for the Interests tendered.  These risks
include the potential for greater  volatility due to decreased  diversification.
However,  the Fund believes that this result is unlikely given the nature of the
Fund's investment  program.  A reduction in the aggregate assets of the Fund may
result in  Members  that do not tender  Interests  bearing  higher  costs to the
extent that certain  expenses borne by the Fund are relatively fixed and may not
decrease  if assets  decline.  These  effects  may be reduced to the extent that
additional  subscriptions  for Interests are made by new and existing Members on
November 1, 2005 and thereafter from time to time.

               (xi) Not applicable.

               (xii)  The  following  discussion  is a  general  summary  of the
federal income tax  consequences of the repurchase of Interests by the Fund from
Members pursuant to the Offer. Members should consult their own tax advisors for
a complete  description of the tax consequences to them of a repurchase of their
Interests by the Fund pursuant to the Offer.

          In general, a Member from which an Interest is repurchased by the Fund
will be treated as  receiving a  distribution  from the Fund and will  generally
reduce (but not below zero) its adjusted tax basis in its Interest by the amount
of cash and the fair market value of property  distributed to such Member.  Such
Member  generally  will  not  recognize  income  or  gain  as a  result  of  the
repurchase,  except  to the  extent  (if any) that the  amount of  consideration
received by the Member  exceeds such  Member's  then  adjusted tax basis in such
Member's  Interest.  A Member's basis in such Member's Interest will be adjusted
for income, gain or loss allocated (for tax purposes) to such Member for periods
prior to the repurchase of such Interest. Cash distributed to a Member in excess
of the adjusted tax basis of such Member's Interest is taxable as a capital gain
or ordinary income, depending on the circumstances. A Member that has its entire
Interest  repurchased  by the Fund for cash may generally  recognize a loss, but
only to the extent that the amount of  consideration  received  from the Fund is
less than the Member's then adjusted tax basis in such Member's Interest.

          (a) (2) Not applicable.

          (b) Not applicable.

ITEM 5.   PAST CONTRACTS, TRANSACTIONS, NEGOTIATIONS AND AGREEMENTS WITH
          RESPECT TO THE ISSUER'S SECURITIES.

          The Fund's LLC Agreement, which was provided to each Member in advance
of subscribing for Interests,  provide that the Fund's Board of Managers has the
discretion to determine whether the Fund will repurchase  Interests from Members
from time to time pursuant to

                                      -7-


written  tenders.  The Adviser  expects  that it will  recommend to the Board of
Managers  that the Fund  repurchase  Interests  from  Members  twice  each year,
effective as of the last business day in June and December,  in accordance  with
the  offering  materials  of  such  Members.  The  Fund  previously  offered  to
repurchase Interests from Members pursuant to written tender offers effective as
of December 31, 2004 and June 30, 2005.  The Fund is not aware of any  contract,
arrangement,  understanding or relationship relating, directly or indirectly, to
this Offer (whether or not legally  enforceable)  between:  (i) the Fund and the
Adviser  or any  Manager  of the  Fund or any  person  controlling  the  Fund or
controlling  the Adviser or any Manager of the Fund;  and (ii) any person,  with
respect to Interests. However, the LLC Agreement provides that the Fund shall be
dissolved if the Interest of any Member that has submitted a written request, in
accordance  with the terms of the LLC Agreement,  to tender its entire  Interest
for repurchase by the Fund has not been repurchased within a period of two years
of the request.

ITEM 6.   PURPOSES OF THIS TENDER OFFER AND PLANS OR PROPOSALS OF THE ISSUER
          OR AFFILIATE.

          (a) The purpose of the Offer is to provide  liquidity  to Members that
hold  Interests as  contemplated  by and in accordance  with the  procedures set
forth in the LLC Agreement.

          (b)  Interests  that are tendered to the Fund in  connection  with the
Offer will be retired,  although the Fund may issue  Interests from time to time
in transactions  not involving any public offering,  conducted  pursuant to Rule
506 of  Regulation  D under the  Securities  Act of 1933,  as amended.  The Fund
currently expects that it will continue to accept subscriptions for Interests as
of the first day of each calendar quarter, but is under no obligation to do so.

          (c) Neither  the Fund nor the  Adviser nor the Board of Managers  have
any plans or proposals that relate to or would result in: (1) the acquisition by
any person of additional  Interests  (other than the Fund's  intention to accept
subscriptions  for Interests on the first day of each calendar  quarter and from
time to time in the discretion of the Fund) or the disposition of Interests; (2)
an extraordinary transaction,  such as a merger,  reorganization or liquidation,
involving the Fund; (3) any material change in the present  distribution  policy
or indebtedness or capitalization of the Fund; (4) any change in the identity of
the Adviser or the members of the Board of Managers, or in the management of the
Fund including,  but not limited to, any plans or proposals to change the number
or the term of the  members  of the  Board  of  Managers,  to fill any  existing
vacancy  on the  Board  of  Managers  or to  change  any  material  term  of the
investment advisory arrangements with the Adviser, except that, while candidates
to fill a vacancy  are being  considered,  Mr.  Bailey is  serving as an interim
Manager until the vacancy is filled; (5) a sale or transfer of a material amount
of assets of the Fund  (other than as the Board of  Managers  determines  may be
necessary or appropriate to finance all or a portion of the repurchase price for
Interests  to be  acquired  pursuant  to the  Offer  or in  connection  with the
ordinary  portfolio  transactions of the Fund); (6) any other material change in
the Fund's  structure or business,  including any plans or proposals to make any
changes in its fundamental  investment  policies,  as amended,  for which a vote
would be  required  by Section 13 of the 1940 Act; or (7) any changes in the LLC
Agreement or other actions that might impede the  acquisition  of control of the
Fund by any person.  Because  Interests  are not traded in any market,  Sections
(6), (7) and (8) of  Regulation  M-A  ss.229.1006(c)  are not  applicable to the
Fund.

ITEM 7.    SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

                                      -8-


          (a) The Fund expects that the repurchase price for Interests  acquired
pursuant to the Offer, which will not exceed $30 million (unless the Fund elects
to  repurchase  a  greater  amount),  will be  derived  from  one or more of the
following  sources:  (i) cash on hand; (ii) the proceeds from the sale of and/or
delivery of securities and portfolio assets held by the Fund; and (iii) possibly
borrowings,  as described in paragraph (b) below. The Fund will segregate,  with
its custodian,  cash or U.S.  government  securities or other liquid  securities
equal  to the  value of the  amount  estimated  to be paid  under  any  Notes as
described above.

          (b) Neither  the Fund nor the  Adviser nor the Board of Managers  have
determined  at this time to borrow  funds to  repurchase  Interests  tendered in
connection with the Offer. However,  depending on the dollar amount of Interests
tendered and prevailing general economic and market conditions, the Fund, in its
sole discretion,  may decide to seek to borrow money to finance all or a portion
of the repurchase  price for Interests,  subject to compliance  with  applicable
law. If the Fund finances any portion of the repurchase price in that manner, it
will deposit assets in a special custody account with its custodian, to serve as
collateral  for any amounts so  borrowed,  and if the Fund were to fail to repay
any such amounts, the lender would be entitled to satisfy the Fund's obligations
from the collateral  deposited in the special custody account.  The Fund expects
that the repayment of any amounts  borrowed will be made from  additional  funds
contributed  to the Fund by  existing  and/or  new  Members,  withdrawal  of its
capital from the investment funds in which it has invested,  or from proceeds of
the sale of securities and portfolio assets held by the Fund.

          (d) Not applicable.

ITEM 8.   INTEREST IN SECURITIES OF THE ISSUER.

          (a) Based on August 31, 2005  estimated  values,  there are no persons
holding  interests  that may be deemed to control the Fund, may control a person
that  controls the Fund and/or may be  controlled  by a person  controlling  the
Fund.

          (b) Other than the  acceptance  of  subscriptions  for Interests as of
October 3, 2005, there have been no transactions  involving  Interests that were
effected during the past 60 business days by the Fund, the Adviser,  any Manager
or any person controlling the Fund or the Adviser.

ITEM 9.   PERSONS/ASSETS RETAINED, EMPLOYED, COMPENSATED OR USED.

          No persons have been  employed,  retained or are to be  compensated by
the Fund to make solicitations or recommendations in connection with the Offer.

ITEM 10.  FINANCIAL STATEMENTS.

          (a) (1) Reference is made to the following financial statements of the
Fund,  which the Fund has  prepared and  furnished  to Members  pursuant to Rule
30e-1 under the 1940 Act and filed with the Securities  and Exchange  Commission
pursuant  to Rule  30b2-1  under the 1940 Act,  and  which are  incorporated  by

         Audited financial statements for fiscal year ended March 31, 2005,
         previously filed on EDGAR on Form N-CSR on June 8, 2005.

               (2) The Fund is not  required  to and  does  not  file  quarterly
unaudited  financial  statements  under the Securities  Exchange Act of 1934, as
amended.  The Fund does not have shares, and consequently does not have earnings
per share information.

               (3) Not applicable.

               (4) The Fund does not have shares, and consequently does not have
book value per share information.

          (b) The Fund's  assets  will be reduced by the amount of the  tendered
Interests that are repurchased by the Fund. Thus,  income relative to assets may
be affected by the Offer.  The Fund does not have shares and  consequently  does
not have earnings or book value per share information.

Dear Member:

          Excelsior   Absolute   Return  Fund  of  Funds  Master  Fund,  LLC,  a
closed-end,  non-diversified,  management  investment  company  organized  as  a
Delaware limited liability  company (the "Fund"),  is offering to repurchase for
cash on the terms and  conditions  set forth in this offer to repurchase and the
related Letter of Transmittal (which together  constitute the "Offer") up to $30
million of  interests  in the Fund or  portions  thereof  pursuant to tenders by
members  of the Fund  ("Members")  at a price  equal to their net  asset  value,
determined  as of December 30, 2005,  if the Offer expires on November 10, 2005.
If the Fund  elects to extend  the  tender  offer  period,  for the  purpose  of
determining the repurchase price for tendered interests,  the net asset value of
such  interests will be determined at the close of business on the last business
day of the month in which the Offer  actually  expires.  (As used in this Offer,
the term "Interest" or "Interests," as the context requires,  shall refer to the
interests in the Fund and portions thereof representing  beneficial interests in
the Fund.) This Offer,  which is being made to all Members is  conditioned  on a
minimum of $25,000 in  Interests  being  tendered by a Member  tendering  only a
portion  of an  Interest  for  repurchase,  and  is  subject  to  certain  other
conditions described below.  Interests are not traded on any established trading
market and are subject to strict restrictions on transferability pursuant to the
Fund's Limited  Liability  Company  Agreement dated as of September 2, 2003 (the
"LLC Agreement").

          Members  should  realize that the value of the  Interests  tendered in
this Offer will  likely  change  between  September  30, 2005 (the last time net
asset value was  calculated)  and December 30, 2005, when the value of Interests
tendered  to the  Fund  for  repurchase  will  be  determined  for  purposes  of
calculating the repurchase price of such Interests.  Members  tendering all or a
portion of their Interests should also note that they will remain Members,  with
respect to the  Interests  tendered  and  accepted  for  repurchase  by the Fund
through  December 30, 2005,  the valuation  date of the Offer when the net asset
value of their Interest is calculated. Any tendering Members that wish to obtain
the estimated net asset value of their Interests should contact U.S. Trust Hedge
Fund  Management,  Inc.,  at the  telephone  number or address set forth  below,
Monday through  Friday,  except  holidays,  during normal business hours of 9:00
a.m. to 5:00 p.m. (Eastern Time).

                                      B-1


          Members  desiring to tender all or any portion of their  Interests for
repurchase  in accordance  with the terms of the Offer should  complete and sign
the attached  Letter of Transmittal and mail or fax it to the Fund in the manner
set forth in Section 4 below.

                                    IMPORTANT

          Neither the Fund, nor its investment adviser nor its Board of Managers
make any  recommendation  to any Member as to whether to tender or refrain  from
tendering  Interests.  Members must make their own  decisions  whether to tender
Interests,  and,  if they  choose to do so, the  portion of their  Interests  to
tender.

          Because each Member's  investment decision is a personal one, based on
their own  financial  circumstances,  no person has been  authorized to make any
recommendation  on  behalf  of the  Fund as to  whether  Members  should  tender
Interests  pursuant  to the  Offer.  No person has been  authorized  to give any
information or to make any  representations  in connection  with the Offer other
than those contained  herein or in the Letter of Transmittal.  If given or made,
such recommendation and such information and representations  must not be relied
on as having been authorized by the Fund.

          This  transaction  has neither been  approved nor  disapproved  by the
Securities  and  Exchange  Commission.   Neither  the  Securities  and  Exchange
Commission nor any state  securities  commission  have passed on the fairness or
merits of this  transaction  or on the  accuracy or adequacy of the  information
contained in this document. Any representation to the contrary is unlawful.

                               SUMMARY TERM SHEET

o         As stated in the offering  documents of Excelsior Absolute Return Fund
          of Funds Master Fund, LLC  (hereinafter  "we" or the "Fund"),  we will
          repurchase  your  limited  liability  company  interests  in the  Fund
          ("Interest" or "Interests" as the context requires) at their net asset
          value (that is, the value of the Fund's assets minus its  liabilities,
          multiplied  by the  proportionate  interest  in the Fund you desire to
          redeem).  This offer  (the  "Offer")  will  remain  open  until  12:00
          midnight, Eastern Time, on Thursday,  November 10, 2005 (such time and
          date being hereinafter called the "Initial  Expiration Date"), or such
          later date as corresponds to any extension of the Offer.  The later of
          the Initial  Expiration  Date or the latest time and date to which the
          Offer is extended is called the "Expiration Date." The net asset value
          will be  calculated  for this  purpose on December 30, 2005 or, if the
          Offer is extended,  on the last business day of the month in which the
          Offer actually expires (the "Valuation Date").

o         The   Fund  reserves  the  right  to  adjust  the  Valuation  Date  to
          correspond  with any extension of the Offer.  The Fund will review the
          net asset value  calculation  of  Interests  as of  December  30, 2005
          during the Fund's  audit for its fiscal  year ending  March 31,  2006,
          which the Fund expects will be completed by the end of May 2006.  This
          December  30,  2005 net  asset  value,  as  reviewed,  will be used to
          determine the final amount paid for tendered Interests.

o          You may tender  your  entire  Interest,  a portion of  your  Interest
          defined as a specific  dollar  value or the  portion of your  Interest
          above the minimum required capital account balance. If you tender your
          entire  Interest  (or a portion of your  Interest)  and we accept that
          Interest  for  repurchase,  we will give you a  non-interest  bearing,
          non-transferable  promissory  note (the  "Note") that will be held for
          you in a special custody account with PFPC Trust Company  ("PFPC") and
          will  entitle  you to an amount  equal to the net  asset  value of the
          Interest  tendered  (valued in  accordance  with the Fund's  Liability
          Company  Agreement  dated  September  2, 2003 (the "LLC  Agreement")),
          determined  as of December 30, 2005 (or if the Offer is extended,  the
          net asset value determined on the Valuation Date).

o         If  you tender your entire Interest,  the  Note will entitle you to an
          initial  payment  in cash  and/or  marketable  securities  (valued  in
          accordance  with  the LLC  Agreement)  equal  to at  least  95% of the
          unaudited  net asset value of the  Interest  (the  "Initial  Payment")
          which will be paid to your account with U.S. Trust Company, N.A. or an
          affiliate bank (collectively, "U.S. Trust") or mailed to you if you do
          not have a U.S.  Trust  account,  within 30  calendar  days  after the
          Valuation  Date or, if we have  requested  withdrawals of capital from
          any investment  funds in order to finance the repurchase of Interests,


                                      B-4


          ten  business  days after we have  received  at least 95% of the total
          amount withdrawn from such investment funds.

o         The   Note  will  also  entitle  you  to  a  contingent  payment  (the
          "Contingent  Payment")  equal to the  excess,  if any,  of (a) the net
          asset value of the Interest  tendered as of the Valuation  Date (as it
          may be  adjusted  based  upon the  next  annual  audit  of the  Fund's
          financial  statements)  over (b) the  Initial  Payment.  The Fund will
          deposit the aggregate amount of the Contingent Payments in a separate,
          interest  bearing  account and will pay any interest  actually  earned
          thereon PRO RATA to the Members whose Interests have been repurchased.
          The Contingent  Payment (plus any interest earned) will be paid within
          ten  calendar  days after the  completion  of the Fund's  next  annual
          audit.  The  Contingent  Payment will also be paid to your U.S.  Trust
          account or mailed to you if you do not have a U.S. Trust account.

o         If  you tender only a  portion of your Interest, the Note will entitle
          you to a payment  in cash  and/or  marketable  securities  (valued  in
          accordance with the LLC Agreement)  equal to 100% of the unaudited net
          asset value of the Interest and will be paid to your account with U.S.
          Trust or mailed to you if you do not have a U.S. Trust account, within
          30 calendar  days after the  Valuation  Date or, if we have  requested
          withdrawals of capital from any investment  funds in order to fund the
          repurchase  of  Interests,  within  ten  business  days  after we have
          received  at  least  95% of  the  total  amount  withdrawn  from  such
          investment funds.

o         If you  tender only a  portion of your  Interest,  you are required to
          tender a minimum of $25,000  and you must  maintain a capital  account
          balance of $100,000 or more. We reserve the right to  repurchase  less
          than the amount you tender if the repurchase  would cause your capital
          account to have less than the required minimum balance or if the total
          amount  tendered by members of the Fund  ("Members")  is more than $30
          million.

o         If  we accept the tender of  your entire Interest or a portion of your
          Interest, we will pay the proceeds from: cash on hand;  withdrawals of
          capital  from the  investment  funds in  which we have  invested;  the
          proceeds from the sale of securities and portfolio  assets held by the
          Fund; and/or borrowings (which we do not currently intend to do).

o         Following this  summary is a  formal notice of our offer to repurchase
          your  Interest.  This Offer remains open to you until 12:00  midnight,
          Eastern Time, on Thursday,  November 10, 2005, the expected expiration
          date of the Offer.  Until that time, you have the right to change your
          mind and withdraw any tender of your Interest.  You will also have the
          right to  withdraw  the  tender  of your  Interest  at any time  after
          December  12,  2005,  40 business  days from the  commencement  of the
          Offer, assuming your Interest has not yet been accepted for repurchase
          by the Fund on or before that date.

                                      B-5


 o        If you would like  us  to  repurchase  your  Interest  or a portion of
          your Interest, you should (i) mail the Letter of Transmittal (enclosed
          with the Offer),  to our  investment  adviser,  U.S.  Trust Hedge Fund
          Management,  Inc. (the "Adviser"),  225 High Ridge Road, Stamford,  CT
          06905,  attention  Peggy Lynn,  or (ii) fax it to the Adviser at (203)
          352-4456, so that it is received before 12:00 midnight,  Eastern Time,
          on Thursday,  November  10,  2005.  If you choose to fax the Letter of
          Transmittal, you should mail the original Letter of Transmittal to the
          Adviser promptly after you fax it (although the original does not have
          to be received  before  12:00  midnight,  Eastern  Time,  on Thursday,
          November 10, 2005. Of course,  the value of your Interests will change
          between  September  30,  2005  (the  last  time net  asset  value  was
          calculated)  and December 30,  2005,  when the value of your  Interest
          will be determined for purposes of calculating the repurchase price to
          be paid by us for your Interest.

o         If  you would like to obtain  the  estimated  net asset  value of your
          Interest,  which we calculate  monthly,  based upon the information we
          receive from the managers of the investment  funds in which we invest,
          you may contact  the  Adviser at (203)  352-4497 or at the address set
          forth on page 2, Monday through Friday, except holidays, during normal
          business hours of 9:00 a.m. to 5:00 p.m. (Eastern Time).

o         Please  note,  that just as  you have the right to withdraw the tender
          of your Interest,  we have the right to cancel, amend or postpone this
          Offer at any time before 12:00  midnight,  Eastern  Time, on Thursday,
          November 10, 2005.  Also  realize that  although the Offer  expires on
          Thursday,  November 10, 2005, you will remain a Member with respect to
          the Interest you tendered that is accepted for  repurchase by the Fund
          through  December 30, 2005,  when the net asset value of your Interest
          is calculated.

          1. BACKGROUND AND PURPOSE OF THE OFFER. The purpose of the Offer is to
provide  liquidity to Members that hold  Interests,  as  contemplated  by and in
accordance  with the procedures  set forth in the Fund's LLC Agreement.  The LLC
Agreement,  which was  provided  to each  Member in advance of  subscribing  for
Interests, provide that the board of managers of the Fund (each a "Manager," and
collectively,  the "Board of Managers") has the discretion to determine  whether
the Fund will  repurchase  Interests  from Members from time to time pursuant to
written  tenders.  The Adviser  expects  that it will  recommend to the Board of
Managers  that the Fund offer to  repurchase  Interests  from Members twice each
year, effective as of the last business day of June and December,  in accordance
with the offering  materials of such  Members.  The Fund  previously  offered to
repurchase  Interests from Members  pursuant to written tenders  effective as of
December  31, 2004 and June 30,  2005.  Because  there is no  secondary  trading
market for Interests and  transfers of Interests  are  prohibited  without prior
approval of the Fund, the Board of Managers has determined,  after consideration
of various matters,  that the Offer is in the best interests of Members in order
to provide  liquidity for Interests as contemplated  in the LLC Agreement.  Such
matters include, but are not limited to, the following: whether any Members have
requested  the Fund to  repurchase  their  Interests  or portions  thereof;  the
liquidity  of the  Fund's  assets;  the  investment  plans and  working  capital
requirements  of the Fund;  the


                                      B-6


relative economies of scale with respect to the size of the Fund; the history of
the Fund in  repurchasing  Interests;  the economic  condition of the securities
markets;  and the  anticipated tax  consequences of any proposed  repurchases of
Interests or portions thereof.


          The Board of Managers  intends to consider the continued  desirability
of the Fund  making an offer to  repurchase  Interests  from time to time in the
future, but the Fund is not required to make any such offer.

          The repurchase of Interests pursuant to the Offer will have the effect
of  increasing  the  proportionate  interest in the Fund of Members  that do not
tender  Interests.  Members  that  retain  their  Interests  may be  subject  to
increased risks due to the reduction in the Fund's  aggregate  assets  resulting
from payment for the Interests  tendered.  These risks include the potential for
greater volatility due to decreased diversification.  However, the Fund believes
that this result is unlikely given the nature of the Fund's investment  program.
A reduction  in the  aggregate  assets of the Fund may result in Members that do
not tender  Interests  bearing higher costs to the extent that certain  expenses
borne by the Fund are relatively  fixed and may not decrease if assets  decline.
These  effects may be reduced to the extent that  additional  subscriptions  for
Interests  are  made by new  and  existing  Members  on  November  1,  2005  and
thereafter from time to time.

          Interests that are tendered to the Fund in connection  with this Offer
will be retired,  although the Fund may issue new Interests from time to time in
transactions not involving any public offering conducted pursuant to Rule 506 of
Regulation D under the  Securities  Act of 1933, as amended.  The Fund currently
expects that it will  continue to accept  subscriptions  for Interests as of the
first day of each calendar quarter, but is under no obligation to do so.

          2.  OFFER TO  REPURCHASE  AND PRICE.  The Fund will,  on the terms and
subject to the  conditions  of the Offer,  repurchase up to $30 million of those
outstanding  Interests  that are properly  tendered by Members and not withdrawn
(in  accordance  with Section 5 below) prior to the  Expiration  Date.  The Fund
reserves the right to extend, amend or cancel the Offer as described in Sections
3 and 7 below.  The  repurchase  price of an Interest  tendered  will be its net
asset value on December 30, 2005 or, if the Offer is extended,  on the Valuation
Date,  payable as set forth in Section 6. The Fund  reserves the right to adjust
the  Valuation  Date to correspond  with any  extension of the Offer.  As of the
close of  business  on August 31,  2005,  the  unaudited  net asset  value of an
Interest  corresponding  to an initial  capital  contribution of $250,000 on the
following closing dates of the Fund was as follows:

      If You Invested $250,000              Your Unaudited Net Asset Value As Of
      ON THE FOLLOWING CLOSING DATE         AUGUST 31, 2005 WOULD BE
      -----------------------------         ------------------------

      July 1, 2005                                       $255,657.97

      April 1, 2005                                      $255,452.64

      January 1, 2005                                    $256,620.16

      October 1, 2004                                    $268,520.80

                                      B-7


      If You Invested $250,000              Your Unaudited Net Asset Value As Of
      ON THE FOLLOWING CLOSING DATE         AUGUST 31, 2005 WOULD BE
      -----------------------------         ------------------------


      July 1, 2004                                       $269,839.48

      April 1, 2004                                      $267,886.54

      January 1, 2004                                    $274,952.11

      December 1, 2003                                   $279,901.25


          As  of  the  close  of  business  on  August  31,   2005,   there  was
approximately  $285,198,955 outstanding in capital of the Fund held in Interests
(based on the unaudited  net asset value of the Fund on that date).  Members may
obtain monthly estimated net asset value information,  which the Fund calculates
based on the  information it receives from the managers of the investment  funds
in which the Fund invests,  until the expiration of the Offer, by contacting the
Adviser at the telephone  number or address set forth on page 2, Monday  through
Friday, except holidays,  during normal business hours of 9:00 a.m. to 5:00 p.m.
(Eastern Time).

          3.  AMOUNT OF TENDER.  Subject  to the  limitations  set forth  below,
Members may tender their entire Interest, a portion of their Interest defined as
a specific  dollar  value or the portion of their  Interest  above the  required
minimum capital account  balance,  as described below. A Member that tenders for
repurchase  only a  portion  of such  Member's  Interest  shall be  required  to
maintain a capital  account  balance of $100,000 or more. If a Member tenders an
amount that would cause the Member's  capital  account balance to fall below the
required  minimum,  the Fund  reserves  the  right to  reduce  the  amount to be
repurchased from such Member so that the required minimum balance is maintained.
The  Offer,  which is being made to all  Members,  is  conditioned  on a minimum
amount of $25,000 in  Interests  being  tendered  by the Member if the Member is
tendering only a portion of an Interest for repurchase.

          If the amount of Interests that are properly  tendered pursuant to the
Offer and not withdrawn pursuant to Section 5 below is less than or equal to $30
million (or such greater amount as the Fund may elect to repurchase  pursuant to
the Offer),  the Fund will,  on the terms and subject to the  conditions  of the
Offer,  repurchase  all of the  Interests so tendered  unless the Fund elects to
cancel or amend the Offer,  or postpone  acceptance  of tenders made pursuant to
the Offer, as provided in Section 7 below. If more than $30 million of Interests
are duly  tendered to the Fund prior to the  Expiration  Date and not  withdrawn
pursuant  to Section 5 below,  the Fund will in its sole  discretion  either (a)
accept additional  Interests in accordance with Rule  13e-4(f)(1)(ii)  under the
Securities Exchange Act of 1934, as amended; (b) extend the Offer, if necessary,
and increase the amount of Interests  that the Fund is offering to repurchase to
an amount it believes sufficient to accommodate the excess Interests tendered as
well  as any  Interests  tendered  during  the  extended  Offer;  or (c)  accept
Interests  tendered on or before the  Expiration  Date for payment on a PRO RATA
basis based on the  aggregate net asset value of

                                      B-8



tendered  Interests.  The Offer may be extended,  amended or canceled in various
other circumstances described in Section 7 below.

          4. PROCEDURE FOR TENDERS. Members wishing to tender Interests pursuant
to the  Offer  should  either:  (a) mail a  completed  and  executed  Letter  of
Transmittal  to the Adviser,  to the attention of Peggy Lynn, at the address set
forth on page 2, or (b) fax a completed and executed  Letter of  Transmittal  to
the Adviser, also to the attention of Peggy Lynn, at the fax number set forth on
page 2. The completed and executed Letter of Transmittal must be received by the
Adviser, either by mail or by fax, no later than the Expiration Date.

          The Fund recommends that all documents be submitted to the Adviser via
certified mail, return receipt requested, or by facsimile transmission. A Member
choosing to fax a Letter of Transmittal to the Adviser must also send or deliver
the  original  completed  and  executed  Letter of  Transmittal  to the  Adviser
promptly  thereafter.  Members  wishing  to  confirm  receipt  of  a  Letter  of
Transmittal may contact the Adviser at the address or telephone number set forth
on page 2. The  method of  delivery  of any  documents  is at the  election  and
complete risk of the Member tendering an Interest including, but not limited to,
the  failure  of the  Adviser  to receive  any  Letter of  Transmittal  or other
document submitted by facsimile transmission.  All questions as to the validity,
form,  eligibility (including time of receipt) and acceptance of tenders will be
determined by the Fund, in its sole discretion,  and such determination shall be
final and binding.  The Fund  reserves  the absolute  right to reject any or all
tenders  determined by it not to be in appropriate  form or the acceptance of or
payment for which  would,  in the opinion of counsel for the Fund,  be unlawful.
The Fund also reserves the absolute  right to waive any of the conditions of the
Offer or any defect in any tender with respect to any particular Interest or any
particular Member, and the Fund's  interpretation of the terms and conditions of
the  Offer  will  be  final  and  binding.   Unless   waived,   any  defects  or
irregularities  in connection with tenders must be cured within such time as the
Fund  shall  determine.  Tenders  will not be deemed to have been made until the
defects or  irregularities  have been cured or waived.  Neither the Fund nor the
Adviser  nor the Board of  Managers  shall be  obligated  to give  notice of any
defects or irregularities in tenders,  nor shall any of them incur any liability
for failure to give such notice.

          5. WITHDRAWAL  RIGHTS.  Any Member  tendering an Interest  pursuant to
this Offer may  withdraw  its  tender at any time prior to or on the  Expiration
Date and, if such Member's  Interest has not yet been accepted for repurchase by
the Fund,  at any time  after  December  12,  2005,  40  business  days from the
commencement of the Offer. To be effective, any notice of withdrawal of a tender
must be timely received by the Adviser at the address or fax number set forth on
page 2. A form to give notice of  withdrawal of a tender is available by calling
the Adviser at the telephone number indicated on page 2. All questions as to the
form and validity  (including  time of receipt) of notices of  withdrawal of the
tender  will be  determined  by the  Fund,  in its  sole  discretion,  and  such
determination  shall be  final  and  binding.  A tender  of  Interests  properly
withdrawn  shall not  thereafter  be deemed to be tendered  for  purposes of the
Offer.  However,  withdrawn  Interests  may  be  tendered  again  prior  to  the
Expiration Date by following the procedures described in Section 4.

          6.  REPURCHASES AND PAYMENT.  For purposes of the Offer, the Fund will
be deemed to have accepted (and thereby repurchased) Interests that are tendered
as, if and when, it gives written notice to the tendering Member of its election
to repurchase such Interest.  As

                                      B-9


stated in Section 2 above, the repurchase  price of an Interest  tendered by any
Member will be the net asset value  thereof  determined as of December 30, 2005,
if the Offer expires on the Initial Expiration Date, and otherwise the net asset
value  thereof  as of the last  business  day of the  month in which  the  Offer
expires. The net asset value will be determined after all allocations to capital
accounts of the Member required to be made by the LLC Agreement have been made.

          Members may tender their entire Interest,  a portion of their Interest
defined as a specific  dollar value or the portion of their  Interest  above the
required  minimum capital account  balance.  Each Member that tenders its entire
Interest or a portion  thereof that is accepted for  repurchase  will be given a
Note within ten calendar  days of the  acceptance  of the Member's  Interest for
repurchase.  The Note will be held for the Member in a special  custody  account
with PFPC.  The Note will  entitle the Member to be paid an amount  equal to the
value,  determined as of the Valuation  Date, of the Interest or portion thereof
being  repurchased  (subject to  adjustment  upon  completion of the next annual
audit of the Fund's financial statements).  This amount will be the value of the
Member's capital account (or the portion thereof being  repurchased)  determined
as of the Valuation  Date and will be based on the net asset value of the Fund's
assets  determined as of that date, after giving effect to all allocations to be
made as of that date.

          If a Member  tenders its entire  Interest,  the Note will  entitle the
Member to receive  an  Initial  Payment  in cash  and/or  marketable  securities
(valued  in  accordance  with the LLC  Agreement)  equal to at least  95% of the
unaudited net asset value of the Interest  tendered and accepted for  repurchase
by the Fund, determined as of the Valuation Date. Payment of this amount will be
made  within  30  calendar  days  after the  Valuation  Date or, if the Fund has
requested  withdrawals  of its  capital  from any  investment  funds in order to
finance the repurchase of Interests, within ten business days after the Fund has
received at least 95% of the  aggregate  amount  withdrawn by the Fund from such
investment  funds.  The Note will also  entitle a Member to receive a Contingent
Payment equal to the excess,  if any, of (a) the net asset value of the Interest
tendered  by the  Member  and  accepted  by the  Fund for  repurchase  as of the
Valuation  Date,  as it may be adjusted  based on the next  annual  audit of the
Fund's March 31, 2006, financial  statements,  over (b) the Initial Payment. The
Fund will deposit the aggregate amount of the Contingent Payments in a separate,
interest  bearing account and will pay any interest  actually earned thereon PRO
RATA to the  Members  whose  Interests  have been  repurchased.  The  Contingent
Payment  (plus any  interest  earned) will be payable  within ten calendar  days
after the completion of the Fund's next annual audit. It is anticipated that the
annual audit of the Fund's financial statements will be completed within 60 days
after March 31, 2006, the fiscal year end of the Fund.

          A Member that tenders for  repurchase  only a portion of such Member's
Interest  will  receive a Note that will entitle the Member to a payment in cash
and/or marketable securities (valued in accordance with the LLC Agreement) equal
to 100% of the net asset  value of the  Interest  tendered by the Member that is
accepted for repurchase by the Fund.  Payment  pursuant to the Note will be made
within 30 calendar days after the  Valuation  Date or, if the Fund has requested
withdrawals  of its capital  from any  investment  funds in order to finance the
repurchase of Interests, within ten business days after the Fund has received at
least 95% of the  aggregate  amount  withdrawn by the Fund from such  investment
funds.

                                      B-10


          Although  the Fund has  retained the option to pay all or a portion of
the repurchase price for Interests by distributing  marketable  securities,  the
repurchase price will be paid entirely in cash except in the unlikely event that
the  Board  of  Managers  determines  that the  distribution  of  securities  is
necessary to avoid or mitigate any adverse  effect of the Offer on the remaining
Members.  In such event, the Fund would make such payment on a pro rata basis so
that each Member would receive the same type of consideration.

          The Note  pursuant to which  Members will receive the Initial  Payment
and Contingent  Payment  (together,  the  "Payments")  will be held in a special
custody account with PFPC for the benefit of Members tendering  Interests in the
Fund.  All payments due pursuant to the Note will also be deposited  directly to
the tendering  Member's  account at U.S. Trust if the Member has an account with
U.S.  Trust and will be subject upon  withdrawal  from such accounts to any fees
that U.S. Trust would  customarily  assess upon the withdrawal of cash from such
account.  Those  Members that do not have a U.S.  Trust account will receive any
payments due under the Note through the mail at the address listed in the Fund's
records unless the Fund is advised in writing of a change of address.

          It is expected that cash payments for Interests  acquired  pursuant to
the  Offer,  which  will not  exceed  $30  million  (unless  the Fund  elects to
repurchase  a greater  amount),  will be  derived  from:  (a) cash on hand;  (b)
withdrawal of capital from the investment  funds in which the Fund invests;  (c)
the proceeds from the sale of securities and portfolio  assets held by the Fund;
and/or (d) possibly borrowings, as described below. The Fund will segregate with
its custodian  cash or U.S.  government  securities  or other liquid  securities
equal to the  value of the  amount  estimated  to be paid  under the  Notes,  as
described above. Neither the Fund nor the Board of Managers nor the Adviser have
determined  at this time to borrow  funds to  repurchase  Interests  tendered in
connection with the Offer. However,  depending on the dollar amount of Interests
tendered and prevailing general economic and market conditions, the Fund, in its
sole  discretion,  may decide to finance  any portion of the  repurchase  price,
subject to compliance  with  applicable  law,  through  borrowings.  If the Fund
finances any portion of the  repurchase  price in that  manner,  it will deposit
assets  in a special  custody  account  with its  custodian,  PFPC,  to serve as
collateral  for any amounts so  borrowed,  and if the Fund were to fail to repay
any such amounts, the lender would be entitled to satisfy the Fund's obligations
from the collateral  deposited in the special custody account.  The Fund expects
that the repayment of any amounts  borrowed will be made from  additional  funds
contributed  to the Fund by existing  and/or new Members,  withdrawal of capital
from the  investment  funds in which it has invested or from the proceeds of the
sale of securities and portfolio assets held by the Fund.

          7. CERTAIN  CONDITIONS OF THE OFFER.  The Fund reserves the right,  at
any time and from time to time,  to extend the period of time  during  which the
Offer is pending by notifying  Members of such extension.  In the event that the
Fund so elects to extend the tender period,  for the purpose of determining  the
repurchase price for tendered  Interests,  the net asset value of such Interests
will be  determined  as of the close of business on the last business day of the
month in which the Offer  expires.  During  any such  extension,  all  Interests
previously tendered and not withdrawn will remain subject to the Offer. The Fund
also reserves the right,  at any time and from time to time, up to and including
acceptance  of tenders  pursuant  to the Offer,  to: (a) cancel the Offer in the
circumstances  set  forth in the  following  paragraph  and in the event of such
cancellation not to repurchase or pay for any Interests tendered pursuant to the
Offer;  (b)

                                      B-11


amend the Offer; and (c) postpone the acceptance of Interests for repurchase. If
the Fund  determines  to  amend  the  Offer or to  postpone  the  acceptance  of
Interests tendered, it will, to the extent necessary,  extend the period of time
during  which  the Offer is open as  provided  above  and will  promptly  notify
Members.

          The Fund may  cancel  the  Offer,  amend  the  Offer or  postpone  the
acceptance  of tenders made  pursuant to the Offer if: (a) the Fund would not be
able  to  liquidate  portfolio  securities  in a  manner  that  is  orderly  and
consistent  with  the  Fund's  investment  objective  and  policies  in order to
repurchase  Interests  tendered  pursuant  to the  Offer;  (b)  there is, in the
judgment of the Board of Managers, any (i) legal action or proceeding instituted
or threatened  challenging the Offer or otherwise materially adversely affecting
the  Fund,  (ii)  declaration  of a  banking  moratorium  by  federal  or  state
authorities  or any  suspension  of payment by banks in the United States or the
State of Connecticut that is material to the Fund,  (iii) limitation  imposed by
federal or state authorities on the extension of credit by lending institutions,
(iv) suspension of trading on any organized exchange or over-the-counter  market
where the Fund has a material  investment,  (v) commencement of war, significant
change in armed hostilities or other international or national calamity directly
or indirectly  involving the United States since the  commencement  of the Offer
that is material to the Fund,  (vi) material  decrease in the net asset value of
the Fund from the net asset value of the Fund as of  commencement  of the Offer,
or (vii) other event or condition  that would have a material  adverse effect on
the Fund or its  Members  if  Interests  tendered  pursuant  to the  Offer  were
repurchased;  or (c) the Board of Managers determines that it is not in the best
interest of the Fund to  repurchase  Interests  pursuant to the Offer.  However,
there can be no assurance that the Fund will exercise its right to extend, amend
or cancel the Offer or to postpone acceptance of tenders pursuant to the Offer.

          8. CERTAIN  INFORMATION  ABOUT THE FUND. 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. It is organized as a
Delaware limited liability company.  The principal office of the Fund is located
at 225 High Ridge Road,  Stamford,  CT 06905 and the  telephone  number is (203)
352-4497.  Interests are not traded on any  established  trading  market and are
subject to strict restrictions on transferability pursuant to the LLC Agreement.

          Neither the Fund nor the  Adviser  nor the Board of Managers  have any
plans or proposals that relate to or would result in: (a) the acquisition by any
person of  additional  Interests  (other  than the  Fund's  intention  to accept
subscriptions  for Interests on the first day of each calendar  quarter and from
time to time in the discretion of the Fund) or the disposition of Interests; (b)
an extraordinary  corporate  transaction,  such as a merger,  reorganization  or
liquidation,  involving  the  Fund;  (c)  any  material  change  in the  present
distribution  policy or  indebtedness  or  capitalization  of the Fund;  (d) any
change  in the  identity  of the  investment  adviser  of  the  Fund,  or in the
management of the Fund including,  but not limited to, any plans or proposals to
change the number or the term of the members of the Board of  Managers,  to fill
any existing  vacancy on the Board of Managers or to change any material term of
the  investment  advisory  arrangement  with the  Adviser,  except  that,  while
candidates to fill a vacancy are being  considered,  Mr. Bailey is serving as an
interim  Manager  until the  vacancy  is  filled;  (e) a sale or  transfer  of a
material  amount  of  assets of the Fund  (other  than as the Board of  Managers
determines  may be  necessary  or  appropriate  to  finance  any  portion of the
repurchase price for

                                      B-12


Interests  acquired  pursuant  to this  Offer  or in  connection  with  ordinary
portfolio transactions of the Fund); (f) any other material change in the Fund's
structure or business,  including  any plans or proposals to make any changes in
its  fundamental  investment  policies,  as  amended,  for which a vote would be
required by Section 13 of the 1940 Act; or (g) any changes in the LLC  Agreement
or other actions that may impede the  acquisition  of control of the Fund by any
person.

          Other than the acceptance of subscriptions for Interests on October 3,
2005, there have been no transactions involving the Interests that were effected
during the past 60 business days by the Fund, the Adviser,  any Manager,  or any
person controlling the Fund or the Adviser.

          Based on August 31, 2005 estimated values, there are no
persons holding interests that may be deemed to control the Fund, may control a
person that controls the Fund and/or may be controlled by a person controlling
the Fund.

          9. CERTAIN FEDERAL INCOME TAX CONSEQUENCES.  The following  discussion
is a general summary of the federal income tax consequences of the repurchase of
Interests by the Fund from Members pursuant to the Offer. Members should consult
their own tax advisors for a complete  description  of the tax  consequences  to
them of a repurchase of their Interests by the Fund pursuant to the Offer.

          In general, a Member from which an Interest is repurchased by the Fund
will be treated as  receiving a  distribution  from the Fund and will  generally
reduce (but not below zero) its adjusted tax basis in its Interest by the amount
of cash and the fair market value of property  distributed to such Member.  Such
Member  generally  will  not  recognize  income  or  gain  as a  result  of  the
repurchase,  except  to the  extent  (if any) that the  amount of  consideration
received by the Member  exceeds such  Member's  then  adjusted tax basis in such
Member's  Interest.  A Member's basis in such Member's  Interest will be reduced
(but not below zero) by the amount of consideration  received by the Member from
the Fund in connection with the repurchase of such Interest. A Member's basis in
such Member's Interest will be adjusted for income,  gain or loss allocated (for
tax  purposes)  to such  Member  for  periods  prior to the  repurchase  of such
Interest.  Cash  distributed  to a Member in excess of the adjusted tax basis of
such Member's Interest is taxable as capital gain or ordinary income,  depending
on the circumstances.  A Member that has its entire Interest  repurchased by the
Fund for cash may  generally  recognize a loss,  but only to the extent that the
amount of  consideration  received  from the Fund is less than the Member's then
adjusted tax basis in such Member's Interest.

          10. MISCELLANEOUS. The Offer is not being made to, nor will tenders be
accepted from,  Members in any jurisdiction in which the Offer or its acceptance
would not comply with the securities or Blue Sky laws of such jurisdiction.  The
Fund is not aware of any  jurisdiction  in which the Offer or  tenders  pursuant
thereto would not be in compliance with the laws of such jurisdiction.  However,
the  Fund  reserves  the  right  to  exclude  Members  from  the  Offer  in  any
jurisdiction in which it is asserted that the Offer cannot lawfully be made. The
Fund  believes  such  exclusion  is  permissible   under   applicable  laws  and
regulations,  provided  the Fund  makes a good faith  effort to comply  with any
state law deemed applicable to the Offer.

                                      B-13

EXCELSIOR ABSOLUTE RETURN FUND OF FUNDS MASTER FUND, LLC - LETTER OF TRANSMITTAL


Ladies and Gentlemen:

          The  undersigned  hereby tenders to Excelsior  Absolute Return Fund of
Funds Master Fund,  LLC, a closed-end,  non-diversified,  management  investment
company  organized  under the laws of the State of Delaware  (the  "Fund"),  the
limited  liability  company interest in the Fund  (hereinafter the "Interest" or
"Interests" as the context requires) or portion thereof held by the undersigned,
described  and specified  below,  on the terms and  conditions  set forth in the
offer to  repurchase,  dated  October  14,  2005,  receipt  of  which is  hereby
acknowledged,  and in this Letter of Transmittal (which together  constitute the
"Offer"). THE TENDER AND THIS LETTER OF TRANSMITTAL ARE SUBJECT TO ALL THE TERMS
AND  CONDITIONS  SET FORTH IN THE  OFFER,  INCLUDING,  BUT NOT  LIMITED  TO, THE
ABSOLUTE RIGHT OF THE FUND TO REJECT ANY AND ALL TENDERS  DETERMINED BY FUND, IN
ITS SOLE DISCRETION, NOT TO BE IN THE APPROPRIATE FORM.

          The  undersigned  hereby  sells to the Fund the  Interest  or  portion
thereof tendered hereby pursuant to the Offer.  The undersigned  hereby warrants
that the  undersigned has full authority to sell the Interest or portion thereof
tendered  hereby and that the Fund will  acquire  good title  thereto,  free and
clear of all liens, charges, encumbrances, conditional sales agreements or other
obligations  relating to the sale thereof, and not subject to any adverse claim,
when and to the  extent  the same  are  repurchased  by it.  Upon  request,  the
undersigned  will  execute and deliver any  additional  documents  necessary  to
complete the sale in accordance with the terms of the Offer.

          The undersigned  recognizes that under certain circumstances set forth
in the Offer, the Fund may not be required to repurchase any of the Interests in
the Fund or portions thereof tendered hereby.

          A promissory  note for the  repurchase  price will be deposited into a
special custody account with PFPC Trust Company ("PFPC"). The initial payment of
the  repurchase  price for the  Interest  or  portion  thereof  tendered  by the
undersigned will be made by transfer of the funds to the  undersigned's  account
at U.S. Trust Company,  N.A. or an affiliate bank (collectively,  "U.S. Trust"),
or mailed to the address of record for the undersigned if the  undersigned  does
not have a U.S.  Trust  account,  as  described  in Section 6 of the Offer.  The
undersigned hereby represents and warrants that the undersigned understands that
upon a withdrawal of such cash payment from a U.S. Trust account, U.S. Trust may
subject such  withdrawal to any fees that U.S.  Trust would  customarily  assess
upon the withdrawal of cash from such account.

          The  promissory  note will also  reflect the  contingent  payment (the
"Contingent  Payment")  portion of the repurchase price, if any, as described in
Section 6 of the Offer. Any Contingent  Payment of cash due pursuant to the Note
will also be deposited directly to the undersigned's account with U.S. Trust, or
will be mailed to the undersigned if the undersigned  does not have a U.S. Trust
account. Upon a withdrawal of such cash from such account, U.S. Trust may impose
such fees as it would  customarily  assess upon the withdrawal of cash from such
account. The undersigned  recognizes that the amount of the repurchase price for
Interests will be based on the unaudited net asset value of the Fund, determined
as of December  30,  2005,  subject to an extension of the Offer as described in
Section 7. The Contingent  Payment portion of the repurchase price, if any, will
be determined  upon completion of the audit of the Fund's  financial  statements
which is  anticipated  to be  completed  not later than 60 days after  March 31,
2006,  the Fund's  fiscal year end,  and will be paid within ten  calendar  days
thereafter.

          All authority herein conferred or agreed to be conferred shall survive
the death or incapacity of the undersigned and the obligation of the undersigned
hereunder shall be binding on the heirs,  personal  representatives,  successors
and assigns of the undersigned. Except as stated in Section 5 of the Offer, this
tender is irrevocable.

 [THIS LETTER IS SENT IF THE MEMBER TENDERED ITS ENTIRE INTEREST IN THE FUND.]


                                                        November 30, 2005


Dear Member:

          Excelsior  Absolute Return Fund of Funds Master Fund, LLC (the "Fund")
has received and accepted for repurchase  your tender of your limited  liability
company  interest  in  the  Fund  ("Interest"  or  "Interests"  as  the  context
requires).

          Because you have  tendered  and the Fund has  repurchased  your entire
investment,  you have been paid a note (the "Note")  entitling you to receive an
initial payment of 95% of the repurchase  price based on the unaudited net asset
value of the Fund,  determined as of December 30, 2005,  in accordance  with the
terms of the tender offer.  A cash payment in this amount will be deposited into
your account with U.S. Trust Company,  N.A. or an affiliate bank  (collectively,
"U.S.  Trust") on January 30, 2006 or a check will be mailed to you on that date
if you do not  have a U.S.  Trust  account,  unless  the  valuation  date of the
Interests has changed or the Fund has requested a withdrawal of its capital from
the  investment  funds in which it has  invested  and has not yet  received  the
proceeds of that withdrawal, in accordance with the terms of the tender offer.

          The terms of the Note provide that a contingent  payment  representing
the  balance  of the  repurchase  price,  if any,  will be paid to you after the
completion of the Fund's fiscal year-end audit and is subject to fiscal year-end
audit adjustment.  This amount,  will be paid within ten calendar days after the
conclusion of the fiscal  year-end  audit, or on such earlier date as the Fund's
Board of Managers may determine,  according to the terms of the tender offer and
will also be deposited  into your U.S. Trust account or will be mailed to you if
you do not have a U.S. Trust account. We expect the audit to be completed by the
end of May 2006.

          Should you have any questions,  please feel free to contact the Fund's
adviser, U.S. Trust Hedge Fund Management, Inc. at (203) 352-4497.

                                                  Sincerely,

has  received  and  accepted  for  repurchase  your  tender of a portion of your
limited liability company interest in the Fund ("Interest" or "Interests" as the

an initial  payment of 100% of the  repurchase  price based on the unaudited net
asset value of the Fund,  determined as of December 30, 2005, in accordance with
