ITEM 1.        SUMMARY TERM SHEET.

               As stated in the Limited  Liability  Company  Agreement (the "LLC
Agreement") of Old Mutual Absolute Return Master Fund,  L.L.C.  (the "Company"),
the Company is offering to purchase limited  liability  company interests in the
Company ("Interest" or "Interests," as the context requires) from members of the
Company  ("Members")  at their  net  asset  value  (that  is,  the  value of the
Company's assets minus its liabilities, multiplied by the proportionate interest
in the Company a Member desires to tender). The offer to purchase Interests (the
"Offer")  will remain open until 12:00  midnight,  Eastern  time, on October 27,
2008 (the "Expiration  Date") unless the Offer is extended.  The net asset value
of the Interests will be calculated for this purpose as of December 31, 2008 or,
if the Offer is extended,  approximately one month after the Expiration Date (in
each case, the "Valuation  Date").  The Company reserves the right to adjust the
Valuation  Date as a result of any  extension  of the Offer.  The  Company  will
review the net asset value  calculation of Interests  during the Company's audit
for its fiscal year ending  March 31,  2009,  which the Company  expects will be
completed by the end of May 2009 and the audited net asset value will be used to
determine the final amount to be paid for tendered Interests.

               Members  may tender  their  entire  Interest,  a portion of their
Interest  (defined as a specific  dollar  value) or a 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 Company  purchases  that
Interest,   the   Company   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 LLC  Agreement),  determined as of the Valuation  Date. 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 97%
of the net asset value of the  Interest  tendered by the Member that is accepted
for  purchase by the Company  (the  "Initial  Payment")  and will be paid to the
Member  within  one  month  after the  Valuation  Date or,  if the  Company  has
requested  withdrawals  of its  capital  from  any  portfolio  funds in order to
finance the purchase of  Interests,  within ten business  days after the Company
has received at least 90% of the aggregate  amount withdrawn by the Company from
such  portfolio  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 as of the Valuation Date, as it
may be adjusted  based upon the next  annual  audit of the  Company's  financial
statements,  over (b) the Initial  Payment.  The Fund will deposit the aggregate
amount of the Contingent Payments in a separate,  non-interest  bearing account.
The  Contingent  Payment will be payable  promptly  after the  completion of the
Company's  annual  audit.  Proceeds  of the Initial  Payment and the  Contingent
Payment  will be wire  transferred  directly  to an  account  designated  by the
Member.

               A Member  that  tenders  for  repurchase  only a portion  of such
Member's Interest will be required to maintain a minimum capital account balance
of $50,000  (or  $25,000,  in the case of certain  Members,  as set forth in the
offering materials provided to Members).

               The Company  reserves the right to purchase  less than the amount
tendered by a Member if the amount  tendered  would cause the  Member's  capital
account in the Company to have a value less than the required  minimum  balance.
If the Company accepts the tender of the


                                       1





Member's  entire  Interest or a portion of such Member's  Interest,  the Company
will make payment for  Interests it purchases  from one or more of the following
sources:  cash on hand, the proceeds of the sale of and/or delivery of portfolio
securities  held by the Company,  the  withdrawals of its capital from portfolio
funds in which it has  invested,  or by  borrowings  (which the Company does not
intend to do).

               The Offer remains open to Members until 12:00  midnight,  Eastern
time, on October 27, 2008, the expected expiration date of the Offer. Until this
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  November 25,  2008,  if their  Interest has not yet
been accepted for purchase by the Company.

               If a Member  would like the Company to purchase 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 UMB Fund Services, Inc.
(the "Transfer Agent"), at 803 W. Michigan St., Milwaukee,  WI 53233, Attention:
Old Mutual Funds,  or (ii) fax it to the Transfer  Agent at (816)  860-3140,  so
that it is received before 12:00 midnight, Eastern time, on October 27, 2008. IF
THE MEMBER CHOOSES TO FAX THE LETTER OF TRANSMITTAL, IT SHOULD MAIL THE ORIGINAL
LETTER OF TRANSMITTAL TO THE TRANSFER AGENT PROMPTLY AFTER IT IS FAXED (ALTHOUGH
THE ORIGINAL DOES NOT HAVE TO BE RECEIVED BEFORE 12:00  MIDNIGHT,  EASTERN TIME,
ON OCTOBER 27, 2008). Of course,  the value of the Interests will change between
July 31,  2008 (the last time  prior to the date of this  filing as of which net
asset value has been calculated) and the Valuation Date.  Members may obtain the
estimated net asset value of their  Interests,  which the Company will calculate
monthly based upon the information the Company receives from the managers of the
portfolio  funds in which it invests,  by contacting the Transfer Agent at (888)
896-8919 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
see Item 4(a)(9) for a discussion  regarding the  procedures  implemented in the
event the Offer is oversubscribed (I.E., more than $2.9 million of Interests are
duly tendered).

               Please  note that just as each  Member has the right to  withdraw
the  tender  of an  Interest,  the  Company  has the right to  cancel,  amend or
postpone this Offer at any time before 12:00 midnight,  Eastern time, on October
27, 2008.  Also realize that  although the Offer  expires on October 27, 2008, a
Member  that  tenders  its  Interest   will  remain  a  Member  in  the  Company
notwithstanding  the Company's  acceptance of the Member's Interest for purchase
through the Valuation Date.  Accordingly,  the value of a tendered Interest will
remain at risk, until the Valuation Date, because of its investment  pursuant to
the Company's investment program.

ITEM 4.        TERMS OF THIS TENDER OFFER.

               (a)(1)  Subject to the  conditions  set forth in the  Offer,  the
Company  will  purchase up to $2.9  million of  Interests  that are  tendered by
Members and not withdrawn (in accordance  with Item 1) prior to 12:00  midnight,
Eastern time, on the  Expiration  Date, or any later date as  corresponds to any
extension of the offer.

                  (2)  The purchase price of  Interests  tendered to the Company
for purchase will be their net asset value as of the Valuation Date.

                       Members  may  tender  their  entire  Interest,  a portion
of their  Interest  defined  as a  specific  dollar  value or a portion of their
Interest above the required  minimum  capital account  balance.  Each Member who
tenders its entire  Interest or a portion  thereof that is accepted for purchase
will be given a Note promptly upon acceptance of the Member's Interest. 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  purchased
(subject to adjustment upon completion of the next annual audit of the Company's
financial  statements).  This amount will be the value of the  Member's  capital
account (or the portion thereof being purchased)  determined as of the Valuation
Date,  and will be based upon the net asset value of the Company's  assets as of
that date,  after giving effect to all  allocations  to be made as of that date.
The Note will  entitle  the Member to  receive  an initial  payment in an amount
equal to at least 97% of the unaudited net asset value of the Interest  tendered
and accepted  for  purchase by the Company.  Payment of this amount will be made
within one month  after the  Valuation  Date or, if the  Company  has  requested
withdrawals  of its  capital  from  any  portfolio  funds  in  order to fund the
purchase of


                                       3





Interests,  no later than ten  business  days after the Company has  received at
least 90% of the aggregate  amount  withdrawn by the Company from such portfolio
funds.  The Note will also entitle a Member to receive the  Contingent  Payment.
The  Contingent  Payment will be payable  promptly  after the  completion of the
Company's  next annual  audit.  It is  anticipated  that the annual audit of the
Company's financial  statements will be completed within 60 days after March 31,
2009, the fiscal year end of the Company.

                  Although the Company has retained the
option to pay all or a portion of the purchase price by distributing  marketable
securities,  the  purchase  price will be paid  entirely  in cash  except in the
unlikely  event that the Board of Managers of the  Company  determines  that the
distribution  of securities is necessary to avoid or mitigate any adverse effect
of the Offer on the  remaining  Members.

                  The Note  pursuant to which a  tendering  Member will  receive
the Initial Payment and Contingent Payment  (together,  the "Cash Payment") will
be mailed directly to the tendering Member. Any Cash Payment due pursuant to the
Note  will be made by wire  transfer  directly  to the  tendering  Member  to an
account designated by the Member.

                  A  Member who tenders  for repurchase  only a  portion of such
Member's Interest will be required to maintain a minimum capital account balance
of $50,000  (or  $25,000,  in the case of certain  Members,  as set forth in the
offering materials provided to Members).

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

                  (3)  The  scheduled  expiration date of  the  Offer  is  12:00
midnight, Eastern time, October 27, 2008.

                  (4)  Not Applicable.

                  (5)  The Company 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.  The purchase price of an Interest tendered
by any Member will be the net asset value thereof as of the close of business on
December 31, 2008 if the Offer expires on the initial Expiration Date or, if the
Offer is extended, approximately one month after the Expiration Date. During any
such extension,  all Interests previously tendered and not withdrawn will remain
subject to the Offer.  The Company 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 purchase or pay for any Interests tendered pursuant to
the Offer; (b) amend the Offer; and (c) postpone the acceptance of Interests. If
the Company  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.

                  (6) A tender of Interests may be withdrawn  at any time before
12:00  midnight,  Eastern time,  October 27, 2008 and, if Interests have not yet
been accepted for purchase by the Company, at any time after November 25, 2008.

                  (7)  Members wishing to tender Interests pursuant to the Offer
should mail a completed  and  executed  Letter of  Transmittal  to the  Transfer
Agent,  to the attention of Old Mutual Funds, at the address set forth on page 2
of the Offer,  or fax a completed  and  executed  Letter of  Transmittal  to the
Transfer Agent, also to the attention of Old Mutual Funds,


                                       4





at the fax number set forth on page 2 of the Offer.  The  completed and executed
Letter of Transmittal must be received by the Transfer Agent,  either by mail or
by fax,  no later than the  Expiration  Date.  The Company  recommends  that all
documents be submitted to the Transfer Agent by certified  mail,  return receipt
requested,  or by facsimile  transmission.  A Member choosing to fax a Letter of
Transmittal  to the  Transfer  Agent  must also  send or  deliver  the  original
completed and executed  Letter of  Transmittal  to the Transfer  Agent  promptly
thereafter.

                  Any  Member  tendering an Interest  pursuant to the  Offer may
withdraw its tender as described  above in Item 4(a)(6).  To be  effective,  any
notice  of  withdrawal  must be timely  received  by the  Transfer  Agent 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 Transfer  Agent at
the  telephone  number  indicated on page 2 of the Offer.  A tender of Interests
properly  withdrawn will not thereafter be deemed to be tendered for purposes of
the  Offer.  However,  subsequent  to  the  withdrawal  of  tendered  Interests,
Interests may be tendered  again prior to the  Expiration  Date by following the
procedures described above.

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

                  (9)  If more than $2.9 million of Interests are duly  tendered
to the Company prior to the Expiration  Date and not withdrawn,  the Company may
in its sole  discretion:  (a) accept the  additional  Interests  permitted to be
accepted pursuant to Rule  13e-4(f)(1)(ii)  under the Securities Exchange Act of
1934, as amended (the "1934 Act"); or (b) amend and extend the Offer to increase
the amount of Interests  that the Company is offering to purchase.  In the event
the amount of  Interests  duly  tendered  exceeds  the amount of  Interests  the
Company has offered to purchase  pursuant to the Offer or any amendment  thereof
(including  the  amount of  Interests,  if any,  the  Company  may be willing to
purchase as permitted by Rule  13e-4(f)(1)(ii)  under the 1934 Act), the Company
will accept Interests duly 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 (5) above.

                  (10) The purchase of Interests pursuant to the Offer may  have
the effect of increasing  the  proportionate  interest in the Company of Members
who do not tender Interests.  Members that retain their Interests may be subject
to increased  risks that may possibly result from the reduction in the Company's
aggregate assets resulting from payment for the Interests tendered.  These risks
include the potential for greater  volatility due to decreased  diversification.
However,  the Company  believes that this result is unlikely given the nature of
the Company's  investment  program.  A reduction in the aggregate  assets of the
Company may result in Members that do not tender Interests  bearing higher costs
to the extent that certain  expenses borne by the Company are  relatively  fixed
and may not  decrease  if  assets  decline.  These  effects  may be  reduced  or
eliminated to the extent that additional subscriptions for Interests are made by
new and existing Members on October 1, 2008 and thereafter from time to time.

                  (11) Not Applicable.

                  (12) The  following  discussion is a  general summary  of  the
Federal income tax consequences of the purchase of Interests by the Company 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 purchase of their
Interests by the Company pursuant to the Offer.


                                       5





                  In general,  a Member from  which an Interest is  purchased by
the Company will be treated as receiving a distribution  from the Company.  Such
Member  generally will not recognize income or gain as a result of the purchase,
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  Interest  will be adjusted  for income,  gain or loss
allocated (for tax purposes) to such Member for periods prior to the purchase 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 purchased
by the Company may generally  recognize a loss,  but only to the extent that the
amount of consideration received from the Company is less than the Member's then
adjusted tax basis in such Member's Interest.

                       (i)   Not Applicable.


                       (ii)  Not Applicable.


                       (iii) Not Applicable.


                       (iv)  Not Applicable.


                       (v)   Not Applicable.


                       (vi)  Not Applicable.


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

               The Company's LLC Agreement, which was provided to each Member in
advance of  subscribing  for  Interests,  provides that the  Company's  Board of
Managers has the sole discretion to determine  whether the Company will purchase
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 Company
purchase  Interests from Members  quarterly,  effective as of March 31, June 30,
September 30 and December 31, in accordance with the offering  materials of such
Members.  The Company has previously  offered to purchase Interests from Members
pursuant to written tenders,  effective as of December 31, 2007, March 31, 2008,
June 30, 2008 and September 30, 2008.

               The   Company  is  not  aware  of  any   contract,   arrangement,
understanding or relationship relating,  directly or indirectly,  to this tender
offer  (whether or not  legally  enforceable)  between:  (i) the Company and the
Adviser or any Manager of the Company or any person  controlling  the Company or
controlling the Adviser or any Manager of the Company; and (ii) any person, with
respect to Interests. However, the LLC Agreement provides that the Company 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  purchase  by the Company  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)  The   Company   currently   expects   that  it  will  accept
subscriptions  for  Interests as of October 1, 2008 and on the first day of each
month thereafter, but is under no obligation to do so.

               (c) Neither the Company nor the Adviser nor the Board of Managers
has  any  plans  or  proposals  that  relate  to or  would  result  in:  (1) the
acquisition  by any person of  additional  Interests  (other than the  Company's
intention to accept  subscriptions  for Interests on the first day of each month
and from time to time in the discretion of the Company),  or the  disposition of
Interests; (2) an extraordinary transaction, such as a merger, reorganization or
liquidation,  involving  the  Company;  (3) any  material  change in the present
distribution  policy or indebtedness or capitalization  of the Company;  (4) any
change in the  identity of the Adviser or the members of the Board of  Managers,
or in the management of the Company including,  but not limited to, any plans or
proposals  to change the number or the term of members of the Board of Managers,
to fill any existing  vacancy on the Board of Managers or any plans or proposals
to change any material term of the  investment  advisory  arrangements  with the
Adviser;  (5) a sale or transfer  of a material  amount of assets of the Company
(other than as the Board of Managers  determines may be necessary or appropriate
to fund all or a portion of the  purchase  price for  Interests  to be  acquired
pursuant to the Offer or in connection with the ordinary portfolio  transactions
of the Company);  (6) any other  material  change in the Company'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  Company 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 Company.


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


               (a) The Company  expects  that the purchase  price for  Interests
acquired  pursuant to the Offer,  which will not exceed $2.9 million (unless the
Company elects to purchase a greater  amount),  will be derived from one or more
of the  following  sources:  (i) cash on hand;  (ii) the proceeds of the sale of
and/or  delivery of  securities  and portfolio  assets held by the Company;  and
(iii) possibly  borrowings,  as described in paragraph (b),  below.  The Company
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) None of the Company, the Adviser or the Board of Managers has
determined  at this time to  borrow  funds to  purchase  Interests  tendered  in
connection with the Offer. However,  depending on the dollar amount of Interests
tendered and prevailing general economic and market conditions,  the Company, in
its sole  discretion,  may decide to seek to borrow  money to  finance  all or a
portion of the purchase price for Interests, subject to


                                       7





compliance  with  applicable  law.  If the Company  finances  any portion of the
purchase  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 Company were to fail to repay any such  amounts,  the lender would be
entitled to satisfy the Company's  obligations from the collateral  deposited in
the special  custody  account.  The Company  expects  that the  repayment of any
amounts borrowed will be made from additional  funds  contributed to the Company
by existing  and/or new Members,  or from the proceeds of the sale of securities
and portfolio assets held by the Company.

               (c) Not Applicable.

               (d) Not Applicable.

ITEM 8.        INTEREST IN SECURITIES OF THE ISSUER.


               (a)  Based  on  July  31,  2008  estimated  values,   OMUSH  owns
$1,137,520.24 in Interests (approximately 7.09% of the outstanding Interests).

               (b) There have been no transactions involving Interests that were
effected during the past 60 days by the Company, the Adviser, any Manager or any
person controlling the Company, the Adviser or any Manager.

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

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

                  (2)  The  Company  is  not  required  to  and  does  not  file

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

                          UNLESS THE OFFER IS EXTENDED

To the Members of Old Mutual Absolute Return Master Fund, L.L.C.:


               Old Mutual  Absolute  Return Master Fund,  L.L.C.,  a closed-end,
non-diversified,  management  investment company organized as a Delaware limited
liability company (the "Company"), is offering to purchase for cash on the terms
and conditions set forth in this offer to purchase ("Offer to Purchase") and the
related  Letter  of  Transmittal  (which  together  with the  Offer to  Purchase
constitutes  the  "Offer")  up to $2.9  million of  Interests  in the Company or
portions thereof pursuant to tenders by members of the Company  ("Members") at a
price  equal to their net asset  value as of  December  31,  2008,  if the Offer
expires on October 27,  2008,  or, if the Offer is extended,  approximately  one
month  after the  expiration  date of the Offer (in each  case,  the  "Valuation
Date").  (As used in this Offer,  the term  "Interest"  or  "Interests,"  as the
context  requires,  shall refer to the  interests  in the  Company and  portions
thereof representing beneficial interests in the Company.) If the Company elects
to extend the tender period,  for the purpose of determining  the purchase price
for tendered Interests, the net asset value of such Interests will be determined
at the close of business on the Valuation  Date. This Offer is being made to all
Members  and is not  conditioned  on  any  minimum  amount  of  Interests  being
tendered,  but is subject to certain conditions  described below.  Interests are
not  traded  on any  established  trading  market  and  are  subject  to  strict
restrictions  on  transferability  pursuant to the Company's  Limited  Liability
Company Agreement (the "LLC Agreement"), if applicable.

               Members should  realize that the value of the Interests  tendered
in this Offer likely will change  between July 31, 2008 (the last time net asset
value was calculated) and the Valuation Date.  Members tendering their Interests
should also note that they will remain  Members in the Company,  with respect to
the Interest  tendered  and  accepted  for purchase by the Company,  through the
Valuation  Date.  Accordingly,  the value of a tendered  Interest will remain at
risk  until the  Valuation  Date,  because  of its  investment  pursuant  to the
Company's investment program.

Any tendering Members that wish to obtain the estimated net asset value of their
Interests should contact the Company's  transfer agent, UMB Fund Services,  Inc.
(the  "Transfer  Agent"),  at the telephone  numbers 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). Members desiring to tender all






or any  portion of their  Interests  in  accordance  with the terms of the Offer
should  complete and sign the attached  Letter of Transmittal and mail or fax it
to the Company in the manner set forth in Section 4 below.

                                    IMPORTANT

               None of the  Company,  its  investment  adviser  or its  Board of
Managers  makes 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 its financial circumstances,  no person has been authorized to make any
recommendation  on behalf of the  Company 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 Company.

               This  transaction  has not been  approved or  disapproved  by the
Securities  and  Exchange  Commission  (the  "SEC") nor has the SEC or any state
securities commission passed on the fairness or merits of such transaction or on
the  accuracy or adequacy of the  information  contained in this  document.  Any
representation to the contrary is unlawful.

               Questions and requests for assistance and requests for additional
copies of the Offer may be directed to the Transfer Agent.

                               SUMMARY TERM SHEET

                      o As stated in the  Limited  Liability  Company  Agreement
                        (the "LLC  Agreement")  of Old  Mutual  Absolute  Return
                        Master Fund, L.L.C. (hereinafter "we" or the "Company"),
                        we  will   purchase  your  limited   liability   company
                        interests  ("Interest"  or  "Interests"  as the  context
                        requires)  at their net asset  value (that is, the value
                        of  the   Company's   assets   minus  its   liabilities,
                        multiplied by the proportionate  interest in the Company
                        you desire to tender).  This offer to purchase Interests
                        (the  "Offer")  will remain  open until 12:00  midnight,
                        Eastern  time,  on October  27, 2008 unless the Offer is
                        extended (the "Expiration Date").

                      o The net asset value of the Interests  will be calculated
                        for this  purpose  as of  December  31,  2008 or, if the
                        Offer is  extended,  approximately  one month  after the
                        Expiration  Date (in each case, the  "Valuation  Date").
                        The Company  reserves the right to adjust the  Valuation
                        Date as a result  of any  extension  of the  Offer.  The
                        Company will review the net asset value  calculation  of
                        the Interests  during the Company's audit for its fiscal
                        year ending  March 31, 2009,  which the Company  expects
                        will be completed by the end of May 2009 and the audited
                        net  asset  value  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 a portion
                        of your  Interest  above the  required  minimum  capital
                        account balance.  If you tender your entire Interest (or
                        a  portion  of  your  Interest)  and  we  purchase  that
                        Interest,  we  will  give  you  a  non-interest-bearing,
                        non-transferable  promissory note (the "Note") entitling
                        you to an  amount  equal to the net  asset  value of the
                        Interest  tendered  (valued in  accordance  with the LLC
                        Agreement), determined as of the Valuation Date.

                      o The Note will be mailed to you and will  entitle  you to
                        an initial payment in cash and/or marketable  securities
                        (valued  according to the LLC Agreement) equal to 97% of
                        the  net  asset  value  of the  Interest  (the  "Initial
                        Payment") which will be paid to you within 30 days after
                        the Valuation Date or, if we have requested  withdrawals
                        of capital from any portfolio  funds in order to finance
                        the purchase of  Interests,  ten business  days after we
                        have  received  at  least  90% of the  aggregate  amount
                        withdrawn from such portfolio 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  Company's   financial
                        statements) over (b) the Initial Payment.  The Fund will
                        deposit the aggregate amount of the Contingent  Payments
                        in  a  separate,   non-interest   bearing  account.  The
                        Contingent  Payment will be payable  promptly  after the
                        completion of the Company's next annual audit.





                      o If you tender only a portion of your  Interest  you will
                        be  required  to  maintain  a  minimum  capital  account
                        balance of $50,000 (or  $25,000,  in the case of certain
                        Members, as set forth in the offering materials provided
                        to Members).  We reserve the right to purchase less than
                        the amount you tender if the  purchase  would cause your
                        capital  account to have less than the required  minimum
                        balance.

                      o If we accept the  tender of your  entire  Interest  or a
                        portion of your Interest,  we will pay you your proceeds
                        from:  cash on hand,  withdrawals  of  capital  from the
                        portfolio funds in which we have invested,  the proceeds
                        of the sale of and/or  delivery of portfolio  securities
                        held by the Company  and/or by borrowing if the Offer is
                        extended (which we do not intend to do).

                      o Following  this summary is a formal  notice of our offer
                        to repurchase your Interests.  Our Offer remains open to
                        you until 12:00  midnight,  Eastern time, on October 27,
                        2008, 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 November 25, 2008, assuming your Interest has
                        not yet been accepted for repurchase.

                      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 UMB Fund
                        Services,  Inc. at 803 W.  Michigan St.,  Milwaukee,  WI
                        53233,  Attention:  Old Mutual Funds,  or (ii) fax it to
                        the  Transfer  Agent  at (816)  860-3140,  so that it is
                        received before 12:00 midnight, Eastern time, on October
                        27,  2008.  IF YOU FAX THE  LETTER OF  TRANSMITTAL,  YOU
                        SHOULD MAIL THE ORIGINAL  LETTER OF  TRANSMITTAL  TO THE
                        TRANSFER  AGENT  PROMPTLY AFTER YOU FAX IT (ALTHOUGH THE
                        ORIGINAL  DOES  NOT  HAVE TO BE  RECEIVED  BEFORE  12:00
                        MIDNIGHT, EASTERN TIME, ON OCTOBER 27, 2008).

                      o The value of your Interests will change between July 31,
                        2008 (the last time net asset value was  calculated) and
                        the Valuation Date.

                      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 Transfer  Agent at (888)  896-8919 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).

                      o If more than $2.9 million of Interests are duly tendered
                        to the  Company  prior  to the  Expiration  Date and not
                        withdrawn  pursuant to Section 5 below, the Company will
                        in its sole discretion  either (a) accept the additional
                        Interests  permitted  to be  accepted  pursuant  to Rule
                        13e-4(f)(1)(ii)  under the  Securities  Exchange  Act of
                        1934,  as  amended  (the "1934  Act");  or (b) amend and
                        extend the Offer to  increase  the  amount of  Interests
                        that the Company is offering to






                        purchase.  In the event the  amount  of  Interests  duly
                        tendered exceeds the amount of Interests the Company has
                        offered  to  purchase  pursuant  to  the  Offer  or  any
                        amendment thereof (including the amount of Interests, if
                        any, the Company may be willing to purchase as permitted
                        by Rule 13e-4(f)(1)(ii) under the 1934 Act), the Company
                        will  accept  Interests  duly  tendered on or before the
                        Expiration Date for payment on a PRO RATA basis based on
                        the aggregate net asset value of tendered Interests.

                      o Please  note that just as you have the right to withdraw
                        the tender of an Interest,  we have the right to cancel,
                        amend or postpone  this Offer at any time  before  12:00
                        midnight,  Eastern  time,  on  October  27,  2008.  Also
                        realize that  although the Offer  expires on October 27,
                        2008,  you will  remain a Member  of the  Company,  with
                        respect  to  the  Interest  tendered  and  accepted  for
                        purchase by the  Company,  through the  Valuation  Date.
                        Accordingly,  the value of your  tendered  Interest will
                        remain at risk until the Valuation Date,  because of its
                        investment pursuant to the Company's investment program.

               1. BACKGROUND AND PURPOSE OF THE OFFER.


               The purpose of this Offer is to provide  liquidity to Members who
hold  Interests,  as  contemplated  by and in accordance with the procedures set
forth in the Company's LLC Agreement.  The LLC Agreement,  which was provided to
each Member in advance of subscribing for Interests,  provides that the Board of
Managers has the sole discretion to determine  whether the Company will purchase
Interests from Members from time to time pursuant to written tenders. Larch Lane
Advisors LLC, the  investment  adviser of the Company (the  "Adviser"),  expects
that it will  recommend  to the  Board of  Managers  that the  Company  purchase
Interests from Members  quarterly,  effective as of March 31, June 30, September
30 and December 31, in accordance  with the offering  materials of such Members.
The Company has previously  offered to purchase  Interests from Members pursuant
to written tenders,  effective as of December 31, 2007, March 31, 2008, June 30,
2008 and September 30, 2008.  Because there is no secondary  trading  market for
Interests and transfers of Interests are  prohibited  without prior  approval of
the  Company,  the Board of Managers  has  determined,  after  consideration  of
various  matters,  that the Offer is in the best interest 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 Company to repurchase  their  Interests or portions  thereof;  the
liquidity of the Company's  assets;  the  investment  plans and working  capital
requirements of the Company; the relative economies of scale with respect to the
size of the Company; the history of the Company 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  purchase  of  Interests  pursuant  to the Offer may have the
effect of increasing the  proportionate  interest in the Company of Members that
do not tender  Interests.  Members that retain their Interests may be subject to
increased risks due to the reduction in the Company's aggregate assets resulting
from payment for the Interests  tendered.  These risks include the potential for
greater  volatility  due to  decreased  diversification.  However,  the  Company
believes  that  this  result is  unlikely  given  the  nature  of the  Company's
investment program. A reduction in





the  aggregate  assets of the Company  may result in Members  that do not tender
Interests  bearing higher costs to the extent that certain expenses borne by the
Company  are  relatively  fixed and may not  decrease if assets  decline.  These
effects may be reduced or eliminated to the extent that additional subscriptions
for  Interests  are made by new and  existing  Members  on  October  1, 2008 and
thereafter from time to time.


               The Company currently  expects that it will accept  subscriptions
for  Interests  as of  October  1,  2008  and on the  first  day of  each  month
thereafter, but is under no obligation to do so.

               2. OFFER TO PURCHASE AND PRICE.

               Subject to the conditions of the Offer, the Company will purchase
up to $2.9 million of Interests  that are tendered by Members and not  withdrawn
(in accordance with Section 5 below) prior to 12:00  midnight,  Eastern time, on
October 27, 2008 or any later date as  corresponds to any extension of the Offer
(in each case, the "Expiration Date"). The Company reserves the right to extend,
amend or cancel the Offer as described  in Sections 3 and 7 below.  The purchase
price of an Interest  tendered  will be its net asset value as of the  Valuation
Date,  payable  as set forth in  Section 6. The  Company  reserves  the right to
adjust the Valuation Date as a result of any extension of the Offer.

               As of  the  close  of  business  on  July  31,  2008,  there  was
approximately  $16.0  million  outstanding  in  capital of the  Company  held in
Interests (based on the estimated  unaudited net asset value of such Interests).
Members may obtain  monthly  estimated  net asset value  information,  which the
Company  calculates  based upon the information it receives from the managers of
the portfolio  funds in which the Company  invests,  until the expiration of the
Offer,  by contacting the Transfer Agent 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 its Interest will be required to maintain a minimum  capital  account
balance of $50,000 (or $25,000,  in the case of certain Members, as set forth in
the offering materials provided to Members).  If a Member tenders an amount that
would cause the  Member's  capital  account  balance to fall below the  required
minimum,  the Company  reserves  the right to reduce the amount to be  purchased
from such Member so that the required  minimum balance is maintained.  The Offer
is being made to all Members  and is not  conditioned  on any minimum  amount of
Interests being tendered.

               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
$2.9  million  (or such  greater  amount as the  Company  may elect to  purchase
pursuant  to the  Offer),  the  Company  will,  on the terms and  subject to the
conditions of the Offer,  purchase all of the  Interests so tendered  unless the
Company 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 $2.9 million
of Interests are duly tendered to the Company prior to the  Expiration  Date and
not  withdrawn  pursuant  to  Section  5  below,  the  Company  will in its sole
discretion either (a) accept the additional  Interests  permitted to be accepted
pursuant to Rule 13e-4(f)(1)(ii) under the 1934 Act; or (b) amend and extend the
Offer to  increase  the amount of  Interests  that the  Company is  offering  to
purchase.  In the event the amount of Interests duly tendered  exceed the amount
of  Interests  the Company has offered to purchase  pursuant to the Offer or any
amendment thereof (including the amount of Interests, if any, the Company may be
willing to purchase as  permitted by Rule  13e-4(f)(1)(ii)  under the 1934 Act),
the Company will accept Interests duly 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 Section 7 below.

               4. PROCEDURE FOR TENDERS.

               Members wishing to tender Interests  pursuant to the Offer should
mail a completed and executed  Letter of Transmittal to the Transfer  Agent,  to
the attention of Old Mutual Funds,  at the address set forth on page 2, or fax a
completed and executed Letter of Transmittal to the Transfer Agent,  also to the
attention  of Old  Mutual  Funds,  at the fax  number  set  forth on page 2. The
completed and executed  Letter of  Transmittal  must be received by the Transfer
Agent,  either by mail or by fax, no later than 12:00 midnight on the Expiration
Date.

               The Company  recommends  that all  documents  be submitted to the
Transfer Agent via certified  mail,  return receipt  requested,  or by facsimile
transmission.  A Member  choosing to fax a Letter of Transmittal to the Transfer
Agent must also send or deliver the original  completed  and executed  Letter of
Transmittal  to the  Transfer  Agent  promptly  thereafter.  Members  wishing to
confirm receipt of a Letter of Transmittal may contact the Transfer Agent 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  Transfer  Agent 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 Company, in
its sole  discretion,  and such  determination  shall be final and binding.  The
Company  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 Company, be unlawful.  The Company 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  Company'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 Company  shall
determine.  Tenders  will not be deemed to have been made  until the  defects or
irregularities  have been cured or waived.  None of the Company,  the Adviser or
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 such tender at any time prior to or on the Expiration  Date and, at any
time after November 25, 2008,  assuming such Member's  Interest has not yet been
accepted for purchase by the Company. To be effective,  any notice of withdrawal
of a tender must be timely  received by the Transfer Agent at the address or the
fax number set forth on page 2. A form to use to give notice of  withdrawal of a
tender is  available  by calling  the  Transfer  Agent 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 a tender  will be  determined  by the
Company,  in its sole  discretion,  and  such  determination  will be final  and
binding.  A tender of Interests properly withdrawn will 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. PURCHASES AND PAYMENT.

               For  purposes of the Offer,  the  Company  will be deemed to have
accepted (and thereby purchased)  Interests that are tendered as, if and when it
gives written  notice to the  tendering  Member of its election to purchase such
Interest.  As  stated in  Section 2 above,  the  purchase  price of an  Interest
tendered by any Member will be the net asset value  thereof as of the  Valuation
Date.  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.

               For Members who tender their  Interest or a portion  thereof that
is  accepted  for  purchase,  payment of the  purchase  price will  consist of a
non-interest-bearing  non-transferable  promissory note (the "Note") entitling a
Member to an initial and contingent payment. The Note will entitle the Member to
receive  an  initial  payment  of 97% of the  unaudited  net asset  value of the
Interest  tendered and  accepted  for  purchase by the Company.  Payment of this
amount will be made within one month after the Valuation Date or, if the Company
has requested  withdrawals  of its capital from any portfolio  funds in order to
finance the purchase of  Interests,  no later than ten  business  days after the
Company  has  received at least 90% of the  aggregate  amount  withdrawn  by the
Company  from such  portfolio  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  Interests  tendered and accepted for purchase by the Company as of
the Valuation Date,  determined based on the audited financial statements of the
Company for its fiscal year ending March 31, 2009,  over (b) the Initial Payment
(the "Contingent  Payment").  The Note will be delivered to the tendering Member
in the manner set forth below within ten calendar  days after the  acceptance of
the  Member's  Interest.  The Fund  will  deposit  the  aggregate  amount of the
Contingent Payments in a separate,  non-interest bearing account. The Contingent
Payment  will  be  payable  (in the  manner  set  forth  below)  promptly  after
completion  of the audit of the  financial  statements  of the  Company  for its
fiscal  year.  It is  anticipated  that  the  audit of the  Company's  financial
statements will be completed no later than 60 days after March 31, 2009.

                  Although the Company has retained the option to pay all or a
portion of the purchase price by distributing marketable securities, the
purchase 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 of the Company.


                  The Note pursuant to which a tendering Member will receive the
Initial Payment and Contingent Payment (together, the "Cash Payment") will be
mailed directly to the tendering Member. Any Cash Payment due pursuant to the
Note will be made by wire transfer directly to the tendering Member to an
account designated by the Member.

               The  Company  expects  that  the  purchase  price  for  Interests
acquired pursuant to the Offer, which will not exceed $2.9 million,  (unless the
Company  elects to purchase a greater  amount) will be derived from: (a) cash on
hand;  (b) the proceeds of the sale of securities  and portfolio  assets held by
the Company;  and/or (c) possibly  borrowings,  as described  below. The Company
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 Note, as described  above.  Neither the Company,  nor the Board of Managers,
nor the  Adviser  have  determined  at this  time to  borrow  funds to  purchase
Interests  tendered in  connection  with the Offer.  However,  depending  on the
dollar amount of Interests  tendered and prevailing  general economic and market
conditions,  the  Company,  in its sole  discretion,  may decide to finance  any
portion of the  purchase  price,  subject to  compliance  with  applicable  law,
through borrowings. If the Company finances any portion of the purchase price in
that  manner,  it will  deposit  assets in a special  custody  account  with its
custodian,  SEI Private Trust Company, to serve as collateral for any amounts so
borrowed,  and if the Company were to fail to repay any such amounts, the lender
would be entitled  to satisfy  the  Company's  obligations  from the  collateral
deposited in the special custody account. The Company expects that the repayment
of any amounts  borrowed will be made from additional  funds  contributed to the
Company by  existing  and/or new  Members  or from the  proceeds  of the sale of
securities and portfolio assets held by the Company.

               7. CERTAIN CONDITIONS OF THE OFFER.

               The  Company  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.  The purchase price of an Interest tendered
by any Member  will be the net asset  value  thereof as of the  Valuation  Date.
During any such extension,  all Interests  previously tendered and not withdrawn
will remain  subject to the Offer.  The Company 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 purchase or pay
for any Interests  tendered  pursuant to the Offer; (b) amend the Offer; and (c)
postpone the  acceptance  of Interests.  If the Company  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 Company may cancel the Offer, amend the Offer or postpone
the acceptance of tenders made pursuant to the Offer if: (a) the Company would
not be able to liquidate portfolio securities in a manner that is orderly and
consistent with the Company's investment objectives and policies in order to
purchase 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
Company, (ii)





declaration  of a banking  moratorium  by  Federal or state  authorities  or any
suspension  of payment  by banks in the United  States or New York State that is
material  to  the  Company,   (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
Company has a material investment, (v) commencement of war, significant increase
in armed  hostilities or other  international or national  calamity  directly or
indirectly  involving  the United  States that is material to the Company,  (vi)
material decrease in the net asset value of the Company from the net asset value
of the  Company  as of  commencement  of the  Offer,  or  (vii)  other  event or
condition  that  would  have a  material  adverse  effect on the  Company or its
Members if Interests  tendered pursuant to the Offer were purchased;  or (c) the
Board of Managers  determines that it is not in the best interest of the Company
to purchase Interests pursuant to the Offer. However,  there can be no assurance
that the Company 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 COMPANY.

               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. It is organized as a Delaware limited liability company. The
principal  executive office of the Company is located at 800 Westchester Avenue,
S-618,  Rye Brook,  New York 10573 and the telephone  number is (888)  266-2200.
Interests are not traded on any  established  trading  market and are subject to
strict restrictions on transferability pursuant to the LLC Agreement.

               Neither the Company nor the Adviser nor the Board of Managers has
any plans or proposals that relate to or would result in: (a) the acquisition by
any person of additional Interests (other than the Company's intention to accept
subscriptions for Interests on the first day of each month and from time to time
in the  discretion  of the Company),  or the  disposition  of Interests;  (b) an
extraordinary  transaction,  such as a merger,  reorganization  or  liquidation,
involving  the  Company;  (c) any  material  change in the present  distribution
policy or indebtedness or capitalization  of the Company;  (d) any change in the
identity  of the  Adviser  or the  members of the Board of  Managers,  or in the
management of the Company including,  but not limited to, any plans or proposals
to change the number or the term of  members of the Board of  Managers,  to fill
any  existing  vacancy on the Board of  Managers  or any plans or  proposals  to
change  any  material  term of the  investment  advisory  arrangements  with the
Adviser;  (e) a sale or transfer  of a material  amount of assets of the Company
(other than as the Board of Managers  determines may be necessary or appropriate
to fund all or a portion of the  purchase  price for  Interests  to be  acquired
pursuant to the Offer or in connection with the ordinary portfolio  transactions
of the Company);  (f) any other  material  change in the Company'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 might  impede  the  acquisition  of control of the  Company by any
person.

               Based  on  July  31,  2008  estimated  values,  Old  Mutual  (US)
Holdings, Inc. ("OMUSH") owns $1,137,520.24 in Interests (approximately 7.09% of
the outstanding Interests).





               OMUSH,  the  parent  company of the  Adviser,  has  informed  the
Company that it plans on tendering its entire Interest  pursuant to the terms of
the Offer. OMUSH has also informed the Company that the proceeds from the tender
of its Interest will be invested  simultaneously into Old Mutual Absolute Return
Fund,  L.L.C., a feeder fund that invests  substantially  all of its assets into
the  Company.  As a result,  the  Company's  net asset value is not  expected to
change.  Except for the  foregoing,  to the  Company's  knowledge,  no executive
officer,  Manager, or other affiliate plans to tender, and the Company presently
has no plans to purchase the Interest of any executive officer, Manager or other
affiliate of the Company pursuant to the Offer.


               There have been no transactions involving the Interests that were
effected during the past 60 days by the Company, the Adviser, any Manager or any
person controlling the Company or the Adviser or any Manager.

               9. CERTAIN FEDERAL INCOME TAX CONSEQUENCES.

               The  following  discussion  is a general  summary of the  federal
income tax consequences of the purchase of Interests by the Company 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 purchase  of their
Interests by the Company pursuant to the Offer.

               In general,  a Member from which an Interest is  purchased by the
Company  will be treated as  receiving a  distribution  from the  Company.  Such
Member  generally will not recognize income or gain as a result of the purchase,
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 the Member's  Interest will be reduced (but not below zero)
by the  amount of  consideration  received  by the  Member  from the  Company in
connection with the purchase of such Interest.  A Member's basis in the Member's
Interest will be adjusted for income,  gain or loss allocated (for tax purposes)
to such  Member  for  periods  prior  to the  purchase  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  purchased by the Company
may  generally  recognize  a loss,  but only to the  extent  that the  amount of
consideration  received from the Company 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 Company 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
Company 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 Company
believes such exclusion is permissible  under  applicable laws and  regulations,
provided  the  Company  makes a good faith  effort to comply  with any state law
deemed applicable to the Offer.





               The  Company  has  filed an  Issuer  Tender  Offer  Statement  on
Schedule TO with the  Securities  and Exchange  Commission  (the  "SEC"),  which
includes certain  information  relating to the Offer  summarized  herein. A free
copy of such  statement  may be  obtained  from the  Company by  contacting  the
Transfer  Agent at the address and telephone  number set forth on page 2 or from
the  SEC's  internet  web  site,  http://www.sec.gov.  For a fee,  a copy may be
obtained from the public  reference  office of the SEC at Judiciary Plaza, 100 F

Dear Member:

               Old Mutual  Absolute Return Master Fund,  L.L.C.  (the "Company")
has  received  and  accepted  for  purchase  your tender of a limited  liability
company interest ("Interest") in the Company.

               Because you have  tendered  and the Company  has  purchased  your
entire investment, you have been paid a note (the "Note"). The Note entitles you
to receive 97% of the purchase price based on the estimated  unaudited net asset
value of the Company as of December  31, 2008 or, if the tender  offer period is
extended,  approximately  one month after the expiration of the tender offer, in
accordance  with the terms of the tender  offer.  A cash  payment in this amount
will be wire  transferred  to the  account  designated  by you in your Letter of
Transmittal  dated  ____________,  no later than  January 31,  2009,  unless the
valuation  date of the  Interests  has changed,  or the Company has  requested a
withdrawal of its capital from the portfolio funds in which it has invested.

               The  terms  of  the  Note  provide  that  a  contingent   payment
representing  the balance of the  purchase  price,  if any,  will be paid to you
after the completion of the Company's  fiscal year-end audit for the year ending
March 31, 2009 and is subject to fiscal year-end audit  adjustment.  This amount
will be paid within ten days after the conclusion of the fiscal  year-end audit,
or on such  earlier  date as the  Company's  Board of  Managers  may  determine,
according to the terms of the tender offer.  We expect the audit to be completed
by the end of May 2009.

               Should you have any  questions,  please  feel free to contact the
Company's Transfer Agent, UMB Fund Services at (888) 896-8919.

                                   Sincerely,

in accordance with the terms of the tender offer.

               The  terms  of  the  Note  provide  that  a  contingent   payment

your Interest in the Company that you did not tender.
