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 July 25, 2008
(the "Expiration Date") unless the Offer is extended. The net asset value of the
Interests  will be  calculated  for this purpose as of September 30, 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 July 25, 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 August 22, 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 July 25, 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 JULY 25, 2008).  Of course,  the value of the Interests  will change  between
April 30,  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 $2.2 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 July 25, 2008.
Also  realize that  although  the Offer  expires on July 25, 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 $2.2 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,  July 25, 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
September  30, 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,  July 25,  2008 and,  if  Interests  have not yet been
accepted  for purchase by the  Company,  at any time after August 22, 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 $2.2 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 July 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
and June 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 July 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 $2.2  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  April  30,   2008,   estimated   values,   OMUSH  owns
$1,120,721.19 in Interests (approximately 8.0% 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
Offer.

                          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 $2.2  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  September  30,  2008,  if the Offer
expires on July 25, 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  April 30, 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






Old Mutual Absolute Return Master Fund, L.L.C.


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.

Old Mutual Absolute Return Master Fund, L.L.C.


                               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 July 25, 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  September  30, 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.





Old Mutual Absolute Return Master Fund, L.L.C.


          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 July 25, 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 August 22, 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 July 25,
               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 JULY 25, 2008).

          o    The value of your  Interests  will change  between April 30, 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 $2.2 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





Old Mutual Absolute Return Master Fund, L.L.C.


               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 July 25, 2008.  Also  realize  that  although the Offer
               expires  on July  25,  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 and June
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





Old Mutual Absolute Return Master Fund, L.L.C.



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 July 1, 2008 and thereafter from time to
time.

          The Company  currently  expects that it will accept  subscriptions for
Interests as of July 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 $2.2 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 July
25, 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 April 30, 2008, there was approximately
$13.9 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
$2.2  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 $2.2
million of Interests are





Old Mutual Absolute Return Master Fund, L.L.C.



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 August 22, 2008,





Old Mutual Absolute Return Master Fund, L.L.C.



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





Old Mutual Absolute Return Master Fund, L.L.C.



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 $2.2 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






Old Mutual Absolute Return Master Fund, L.L.C.



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

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,

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

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 April 30, 2008  estimated  values,  Old Mutual (US) Holdings,
Inc.  ("OMUSH")  owns  $1,120,721.19  in  Interests  (approximately  8.0% 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







Old Mutual Absolute Return Master Fund, L.L.C.



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

IN THE COMPANY.

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 September  30, 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  October 31,  2008,  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.
